Reconstruction & Repair

Elbow reconstruction & repair: UCL/LUCL, tendon repair, paralytic elbow, and vascularized fibular transfer for massive bone loss.

Overview

Chronic tendon and ligament ruptures, such as those of the distal biceps or elbow medial ulnar collateral ligament (UCL), require careful selection between direct repair and reconstruction. Direct repair is preferred for chronic distal biceps tendon ruptures when possible [9]. When direct repair is not feasible, reconstruction with an autologous tendon graft results in predictably good outcomes [9]. Direct repair, autograft reconstruction, and allograft reconstruction are all viable treatment options for chronic distal biceps tendon ruptures with similar outcomes [1]. For chronic locked anterior shoulder dislocation where reduction is not possible, other surgical reconstruction should be considered [7]. In elbow UCL reconstruction, the modified docking procedure is a safe and predictable technique [59]. A good outcome in elbow medial UCL reconstruction depends on successful surgical reconstruction followed by a thorough rehabilitation program [8]. Revision reattachment of the distal biceps tendon results in acceptable functional outcomes [4].

Complex reconstructions involving bone or nerve deficits demand specialized expertise and timing. Complex procedures such as vascularized fibula autograft reconstruction should be performed by an experienced team [2]. Vascularized fibula autografts provide a long-term, durable outcome with excellent functional results after intercalary resection of the humerus for primary bone tumors, though complications may occur frequently in the first years [2]. Advances in preoperative evaluation and surgical reconstruction have improved functional outcomes in the management of humeral nonunion [3]. For pediatric populations, biologic reconstructions with viable bone autograft can provide more durable long-term reconstructions and growing reconstructions [20]. However, biologic reconstructions with viable bone autograft are associated with high short-term complication rates and donor-site morbidity [20]. Surgery for complex shoulder reconstruction in obstetric brachial plexus injury should be performed at 1 year old or younger to achieve the best results [12]. Neurotization to innervate the deltoid and biceps should be considered a viable adjunct treatment and part of a comprehensive reconstructive plan [18]. Regarding nerve grafting, the results of a series on C5 root grafting to the musculocutaneous nerve using pedicled, vascularized ulnar nerve grafts do not support strong recommendations to use vascularized nerve grafts in the reconstruction of large nerve defects [21].

Anatomy & Pathophysiology

Ligamentous & Soft Tissue Reconstruction

Reconstruction of chronically dislocated elbows, leveraging a thorough understanding of anatomy and biomechanics, can achieve functional and painless joints [36]. For ulnar collateral ligament (UCL) reconstruction, suspension button fixation reliably restores elbow kinematics to the intact state [44]. However, dynamic analyses using a 3-dimensional elbow model indicate that none of the configurations for double-strand lateral UCL reconstruction are isometric [39]. Current evidence regarding the optimal elbow flexion angle for graft fixation in UCL reconstruction possesses a high degree of fragility, requiring further studies with objective measurements [49]. Following UCL repairs and reconstructions, elbow range of motion is reliably preserved or improved with a predictable trajectory of rapid improvement within the first 2 to 4 months [58]. Reattachment of the flexor and extensor tendons at the epicondyle in elbow instability requires improved repair techniques for stabilizers of the elbow [68].

Kinematics & Biomechanics

Posterolateral rotatory instability (PLRI) of the elbow remains to be fully understood [64]. Tenotomy of the long head of the biceps tendon results in increased fatigue of the biceps and an improvement in isometric contraction in elbow flexion that does not reach the power of the contralateral healthy arm [48]. Both the Latarjet procedure with and without a coracoid bone block alter normal joint kinematics by shifting the humeral head apex posteriorly in external rotation [53]. Capsular repair in the modified Bristow procedure significantly alters normal glenohumeral kinematics [66].

Osseous Reconstruction & Arthroplasty

Endoprosthetic reconstruction of the proximal humerus provides a stable platform for elbow and hand function, but actual shoulder function is limited [40]. Hemiarthroplasty for distal humeral fractures maintains elbow range of motion and functional use compared with short-term studies [63]. Reconstruction after proximal ulnar resection using native bone provides good elbow function and is likely to provide long-term stability and durability [67].

Heterotopic Ossification & Contracture

Heterotopic ossification should be considered in patients with a mechanical block to function after elbow injury or surgery [51]. Surgical excision and perioperative prophylaxis using radiation therapy for heterotopic ossification of the elbow following burn injury results in significant gains in elbow motion and upper extremity function with few complications [55]. Operative treatment of elbow contracture in patients twenty-one years of age or younger can result in improved, but not normal, elbow motion in many but not all cases [60].

Surgical Approaches & Neuromuscular Management

The posterior (Boyd) approach to terrible triad injuries allows better visualization of the lateral structures for repair and confers excellent stability to the elbow joint [57]. Management of spastic elbow deformity in adult patients with upper motor neuron syndrome often combines several techniques in a single stage to provide an improved elbow position in patients with and without volitional control [65]. Lower trapezius muscle transfer for elbow extension in children with brachial plexus birth injury demonstrates significant improvements in elbow function and muscle strength without postoperative weakness in elbow flexion [61].

Classification

Contemporary Pectoralis Major Tear Classification: A system for pectoralis major tears incorporates injury timing, injury location, and standardized terminology addressing tear extent to reflect musculotendinous morphology [14].

Intraoperative Ulnar Nerve Instability Classification: A 4-category classification of intraoperative ulnar nerve instability is reproducible within and between reviewers [56].

Clinical Presentation

Chronic Distal Biceps Rupture: Direct repair, autograft reconstruction, or allograft reconstruction are all viable treatment options with similar outcomes [1]. When direct repair is not possible, reconstruction with an autologous tendon graft results in predictably good outcomes [9]. In delayed cases, a positive hook test may predict the need for graft reconstruction [25]. Revision reattachment of the distal biceps tendon results in acceptable functional outcomes [4]. Posterior interosseous nerve palsy after distal biceps repair typically resolves within 3 months, and at the latest, 5 months after surgery [29].

Distal Biceps Short Head Tears: These tears present acutely and have a poor natural history akin to complete tears [6]. Surgical repair of an isolated rupture of the separate insertion of the short head of biceps on the radial tuberosity can offer a good prognosis for functional recovery, including full strength and return to sporting activities [11]. Distal biceps short head tears have good outcomes with acute and delayed reconstruction [6].

Elbow Medial Ulnar Collateral Ligament (MUCL): A good outcome for elbow medial ulnar collateral ligament reconstruction depends on successful surgical reconstruction followed by a thorough rehabilitation program [8].

Cubital Tunnel Syndrome: Revision surgery for cubital tunnel syndrome can be offered in the setting of persistent or recurrent symptoms that are unexplained by an alternative diagnosis [15]. Patients undergoing revision surgery for cubital tunnel syndrome should be counseled that complete resolution of symptoms is unlikely [15].

Shoulder Reconstruction: Interposition graft repairs for irreparable rotator cuff tears have shown some promising 2-year outcomes in patient and physician-reported functional outcomes, regardless of graft type [30]. Surgery for complex shoulder reconstruction in obstetric brachial plexus injury should be performed at 1 year old or younger to achieve the best results [12].

Pectoralis Major Tears: A contemporary injury classification system for pectoralis major tears includes injury timing, injury location, and standardized terminology addressing tear extent to reflect musculotendinous morphology [14].

Quadriceps Tendon: Incomplete quadriceps tendon tears may be managed nonsurgically [13]. Complete quadriceps tendon ruptures are best treated with early surgical repair [13].

Distal Triceps Tendon: Primary repair of distal triceps tendon ruptures yields good, durable patient outcomes with minimal rerupture regardless of repair construct [17].

Achilles Tendon: Reconstructive options are detailed for chronic Achilles ruptures to serve as a framework for treating surgeons in these complex cases [16].

Tibialis Anterior Tendon: A two-stage silicone tube and interposition hamstring tendons graft protocol provides a very good functional outcome for traumatic tibialis anterior tendon rupture in young adults, even in delayed repairs complicated by infection [34].

Iliac Crest Graft Harvesting: If anatomical and technical considerations are respected, such as preserving the outer table and reconstructing the defect, patients can be spared iliac wing fracture following graft harvesting from the anterior iliac crest [35].

Vascularized Fibula Autograft: Vascularized fibula autografts provide a long-term, durable outcome with excellent functional results after intercalary resection of the humerus for primary bone tumors, though complications may occur frequently in the first years [2].

Humeral Nonunion: Advances in preoperative evaluation and surgical reconstruction have improved functional outcomes for humeral nonunion [3].

Investigations

MRI: MRI grading of UCL injuries can help predict return to play and the need for surgery [93].

Treatment

Distal Biceps and Triceps

Indications: Direct repair, autograft reconstruction, and allograft reconstruction are all viable treatment options for chronic distal biceps tendon ruptures with similar outcomes [1]. Distal biceps short head tears have a poor natural history akin to complete tears and have good outcomes with acute and delayed reconstruction [6]. Surgery remains an effective option for treatment failures of partial distal biceps tendon ruptures with no detrimental effects from prior conservative management [84]. Due to heterogeneity in rupture patterns, surgical procedures, and outcome measures, it is difficult to ascertain the superiority of one surgical technique over another for distal triceps tendon ruptures [31].

Surgical Approach / Technique: Anatomic direct repair of chronic distal biceps brachii tendon rupture without interposition graft optimizes the approach using the most secure fixation method and allows anatomic repair without loss of range of movement or function [24].

Pectoralis Major

Indications: Nonoperative management is feasible for elderly, low-demand patients with chronic pectoralis major tears, while repair should be reserved for younger, healthier patients with high functional demands [81].

Surgical Approach / Technique: Reconstruction using a human extracellular matrix scaffold (dermal allograft) for chronic pectoralis major tear can be expected to yield a strong repair and successful outcomes [5]. Transfer of the pectoralis major muscle for irreparable rupture of the subscapularis tendon produces high levels of subjective satisfaction with regard to pain relief, function, and stability [75]. Transfer of segmentally split pectoralis major for irreparable rupture of the subscapularis tendon requires further clinical research to determine whether it results in superior results for patient function or pain relief [90]. Treatment of long thoracic nerve palsy with pectoralis major transfer can significantly improve patient-oriented outcomes, but final clinical outcomes remain guarded and many patients have persistent pain regardless of the transfer technique selected [92].

Rotator Cuff and Subscapularis

Surgical Approach / Technique: Subscapularis transfer is a useful adjunct in the operative treatment of massive rotator cuff tears, facilitating closure of larger defects not amenable to simpler reconstructive techniques [33].

Elbow Ligaments and Instability

Surgical Approach / Technique: Treatment of ulnar collateral ligament (UCL) injuries depends on tear type, with nonoperative management for low-grade partial tears and UCL reconstruction as the gold standard for complete tears [10]. The docking technique for lateral ulnar collateral ligament (LUCL) reconstruction facilitates simple graft tensioning and excellent graft fixation [98].

Shoulder Instability and AC Joint

Indications: If reduction of chronic locked anterior shoulder dislocation is not possible, other surgical reconstruction should be considered [7]. Graft fixation techniques for coracoclavicular ligament reconstruction should be chosen with respect to the preoperative type of instability [100].

Surgical Approach / Technique: Suture button fixation in Latarjet has similar load to failure and clinical outcomes but lower bone resorption compared with screw fixation [85]. Clinically, suture button fixation demonstrated similar functional outcome and range of motion when compared with screw fixation, with the potential benefit of lower rates of graft resorption and hardware-related complications [85]. Non-rigid fixation of the glenoid bone block for recurrent anterior instability and major glenoid bone loss resulted in adequate bone graft healing and osseous incorporation [99]. Combined reconstruction with looped allograft and hardware C-C fixation carried the lowest failure rate for short-term failure rates after acromioclavicular joint reconstruction when controlling for multiple other factors [22]. Acromioclavicular joint reconstruction using peroneus brevis tendon allograft provides excellent initial fixation without metal fixators and enables aggressive therapeutic exercise and early return to sports [87]. Chronic acromioclavicular dislocations can be treated with multidirectional stabilization without grafting; the technique is simple, does not present major complications, and material extraction is unnecessary [28]. Conversion to anatomic coracoclavicular ligament reconstruction (ACCR) shows similar clinical outcomes compared to successful non-operative treatment in chronic primary type III to V acromioclavicular joint injuries at a minimum 5-year follow-up [96].

Humeral and Proximal Humerus Reconstruction

Surgical Approach / Technique: Vascularized fibula autografts are complex procedures that should be performed by an experienced team due to frequent complications in the first years, but successful reconstruction provides a long-term, durable outcome with excellent functional results [2]. Advances in preoperative evaluation and surgical reconstruction have improved functional outcomes for humeral nonunion [3]. Biologic reconstructions with viable bone autograft can provide more durable long-term reconstructions and growing reconstructions in the pediatric population at the expense of high short-term complication rates and donor-site morbidity [20]. Structural autografts used in shoulder joint reconstruction have varying outcomes, with some studies showing good stability and pain relief, while others note unpredictable results or donor site morbidity [79]. Reconstruction of the proximal humerus with allograft-prosthetic composite is associated with graft host nonunion as a common mode of failure [97]. Megaprosthetic replacement in complex distal humerus fractures in elderly patients is a salvage procedure that must be selected and narrowed down, as failure would cause even more complex situations [50]. Treatment of proximal humeral dysplasia epiphysealis hemimelica with custom hemiarthroplasty is a reasonable method to salvage the problem when nonsurgical management has failed [94].

Clavicle and Scapula

Surgical Approach / Technique: Surgical repair with plate fixation and bone grafting achieves high union rates with few complications for adolescent clavicle nonunions [104].

Nerve and Muscle Transfers

Surgical Approach / Technique: Neurotization to innervate the deltoid and biceps should be considered a viable adjunct treatment and part of a comprehensive reconstructive plan [18]. Lower trapezius transfer for brachial plexus injury requires additional studies to define and refine the surgical technique [32]. All reported surgical procedures for trapezius palsy demonstrate reduction in pain, with the best results from the Eden-Lange muscle transfer [77].

Soft Tissue and Flaps

Surgical Approach / Technique: With recent advancements in microsurgical techniques, harvesting flaps in a free-style manner has become a practical reality [26].

Elbow Stiffness and Arthroplasty

Indications: When prevention of elbow stiffness fails, nonoperative followed by operative treatment modalities can be pursued [52].

Surgical Approach / Technique: Treatment of elbow instability includes reconstruction of the soft-tissue envelope, revision of prosthetic components, and possibly the use of allografts [103].

Oncology and Limb Salvage

Other Considerations: The use of a reconstruction method appropriate for the needs of the patient and preoperative counseling regarding expected functional level and activity restrictions are critical for high postoperative satisfaction in limb salvage for neoplasms of the shoulder girdle [71].

Specific Patient Populations and Adjuncts

Other Considerations: Careful postoperative management can help achieve positive functional outcomes for rotator cuff tear reconstruction in wheelchair-bound paraplegic patients [83]. Selective ulnar nerve decompression, capsular branch denervation, and arthroscopic debridement should be considered for young patients with avascular necrosis of the distal humerus and radius due to improved pain relief and low morbidity [70]. Particular attention should be paid to prevention of complications, excellent perioperative pain control, and restoration of abduction during rehabilitation after reconstructive shoulder surgery to ensure patient satisfaction [95]. All-suture anchors offer benefits such as smaller size and bone preservation but require careful deployment to prevent gap formation and may be weakened by decortication [101].

Complications

Infection (PJI): Infection frequency after reconstructive shoulder surgery for proximal humerus tumors is similar to previously reported series, with no differences between reconstruction techniques [19]. Infection developed in 11.7% of patients with massive allografts, with no significant differences in age, graft type, or site between infected and non-infected groups [125]. Two-stage reimplantation for deep periprosthetic joint infection (PJI) following total elbow arthroplasty resulted in infection eradication in 69% of cases, with 31% considered treatment failures secondary to recurrent infection [117, 133]. One-stage revision arthroplasty with complete removal and reimplantation for periprosthetic shoulder infection results in lower reoperation rates for infection and similar clinical outcomes compared to one-stage component exchange and two-stage revision [138]. The brachioradialis muscle flap is a 1-stage procedure with no morbidity to the harvest site that provides stable and adequate coverage even in cases with postoperative infection [139].

Aseptic Loosening / Failure: Both acellular dermal allograft and tensor fascia lata autograft demonstrate high rates of complications and failures at a minimum 2-year follow-up [137]. The revision rate for UCLR with allograft appears greater compared to UCLR with autograft, although this may be secondary to limited allograft literature [135]. Limb salvage with a custom prosthetic knee replacement after resection of a malignant tumor of the distal part of the femur yielded satisfactory overall results and relatively good functional outcomes, although revision was necessary in 43% of patients [141].

Instability: Reconstruction with an osteoarticular allograft after intra-articular resection of the proximal aspect of the humerus has an extremely high rate of complications, including joint instability, fracture of the allograft, and infection [132]. Combined reconstruction with looped allograft and hardware C-C fixation for acromioclavicular joint instability carries the lowest failure rate when controlling for multiple other factors [22]. Severe complications after graft reconstruction for anterior sternoclavicular joint instability are rare, with revision rates as low as 5% [129].

Periprosthetic Fracture / Structural Failure: Substantially higher complication rates were observed in autograft and weave cohorts for distal biceps tendon reconstruction, with more than half of autograft-related complications associated with donor site morbidity [136]. Vascularized fibula autograft reconstruction after intercalary resection of the humerus for primary bone tumors is complex, with frequent complications in the first years, but provides long-term durable outcomes [2].

Nerve Palsy: Long-term outcomes of spinal accessory nerve transfer to the musculocutaneous nerve in birth brachial palsy have yet to be fully demonstrated [134].

Other Considerations: Direct repair, autograft reconstruction, or allograft reconstruction for chronic distal biceps tendon ruptures are viable treatment options with similar outcomes [1]. Revision reattachment of the distal biceps tendon results in acceptable functional outcomes [4]. The complication rate for primary repair of chronic distal biceps tendon tears may be higher than that for early repair [23]. Ulnar collateral ligament reconstruction (UCLR) provides excellent patient-reported and clinical outcomes at medium-term follow-up with low complication and revision rates [123]. The incidence of primary UCL reconstructions among professional pitchers is increasing, while the rate of primary reconstructions requiring revision is decreasing [124]. UCL repair is associated with a significantly higher risk of revision UCL surgery than UCL reconstruction in a national sample [128]. Allografts may be comparable to autografts for crucial effectiveness outcomes in posterior cruciate ligament reconstruction, but insufficient evidence exists to judge crucial safety outcomes due to poor reporting [126]. Complications after osteochondral graft reconstruction for capitellar osteochondritis dissecans lesions are relatively uncommon, and donor-site morbidity is low [120]. The overall complication rate for scapulothoracic fusion in facioscapulohumeral muscular dystrophy is high (41%), requiring cautious patient selection after consideration of nonsurgical treatment [121]. Autologous bone graft is effective for the treatment of post-traumatic bone defects [122]. When patients sustaining terrible triad injuries require secondary surgeries for complications, their ultimate functional outcome scores worsen [127]. Complications are very common in terrible triad injuries of the elbow, with over 25% of patients requiring revision surgery [131]. Patients treated with an external fixator (ExF) or internal joint stabilizer (IJS) for unstable elbow injuries had similar clinical outcomes, but complications and second surgeries were more likely in ExF patients [130]. The complication rate for Coonrad-Morrey total elbow replacement can be high, and recognition of technical problems might lead to reduction of the complication and revision rate [140]. Revision surgery for cubital tunnel syndrome should be offered for persistent or recurrent symptoms unexplained by alternative diagnosis, but complete resolution of symptoms is unlikely [15].

Recovery

Light activity (weeks): Return to desk work and light activities of daily living occurs rapidly for many upper extremity procedures. Approximately 93% of patients who underwent distal triceps repair returned to work by 2.2 ± 3.2 months postoperatively [76]. For distal biceps repairs, modified two-incision techniques and Endobutton repairs allow for safe immediate active range of motion protocols with early return of nearly full range of motion and strength [47, 54].

Full activity (months): Return to sport and manual labor timelines vary significantly by procedure and patient population. Rehabilitation protocols for ulnar collateral ligament (UCL) repair with suture tape augmentation are structured around a 5-phase program with return to sport approaching 20 weeks [37]. In professional baseball pitchers, return to play after revision Tommy John surgery is much lower than after primary reconstruction [89]. Control pitchers who do not require revision UCL reconstruction pitch significantly less, below their pre–primary UCL reconstruction workload [74]. Conversely, Major League Baseball pitchers who require revision UCL reconstruction after returning to play following primary UCL reconstruction pitch at or above their pre–primary UCL reconstruction workload [74].

Complete recovery / outcome plateau (months): Functional outcomes stabilize over extended periods. Clinical and functional outcomes at more than 1 year after distal biceps tendon repair were excellent in both bioabsorbable and nonabsorbable screw groups [116]. Revascularization of the fascia lata following shoulder superior capsule reconstruction plateaus at 12 months postoperation [114]. Females demonstrated favorable clinical outcomes at a mean follow-up of 6 years after operative management of posterolateral rotatory instability, with the majority of elbows returning to a preinjury level of function and sport, regardless of whether they underwent primary or revision surgery [112].

Rehabilitation protocol: Rehabilitation strategies must be tailored to the specific reconstruction. Successful surgical reconstruction of the elbow medial ulnar collateral ligament requires a thorough rehabilitation program for a good outcome [8]. Primary repair of distal triceps tendon ruptures yields good, durable patient outcomes with minimal rerupture regardless of whether transosseous bone tunnels or suture anchor constructs are used [17]. Primary repair of the distal triceps tendon is possible when performed within 12 weeks after injury [38].

Functional milestones: Outcomes are generally favorable for acute repairs and specific chronic reconstructions. Direct repair, autograft reconstruction, and allograft reconstruction for chronic distal biceps tendon ruptures yield similar outcomes [1]. Direct repair is the preferred treatment for chronic distal biceps tendon ruptures when possible [9]. Autologous tendon graft reconstruction results in predictably good outcomes for chronic distal biceps tendon ruptures when direct repair is not possible [9]. Revision distal biceps tendon reattachment results in acceptable functional outcomes [4]. Surgical repair of an isolated rupture of the separate insertion of the short head of the biceps on the radial tuberosity offers a good prognosis for functional recovery, including full strength and return to sporting activities [11]. Treatment of adult brachial plexus injuries within 6 months yields favorable outcomes for the restoration of essential shoulder and elbow function [41]. Free functional muscle transfer is a powerful tool for addressing deficits in both primary and delayed settings of adult brachial plexus injuries [41].

Other Considerations: Several factors influence long-term durability and return-to-play metrics. The complication rate for primary repair of chronic distal biceps tendon tears may be higher than that for early repair [23]. Dropout rates are high among European athletes even after successful ulnar collateral ligament reconstruction using the interference screw technique and triceps fascia autograft [113]. The overall rate of return to pre-injury pitch workload following revision UCL reconstruction is low among professional pitchers [80]. Overall durability decreases significantly after revision Tommy John surgery compared with controls [89]. UCL repair can be considered as an option in the right type of injury for professional baseball players hoping to maximize performance after surgery with minimal recovery time [115]. Despite the restoration of a normal patellar height following reconstruction of chronic patellar tendon rupture with contralateral bone-tendon-bone autograft, function did not return to preinjury level [119].
