RESUMO
PURPOSE: This single-centre study aimed to review the postoperative outcomes of distal biceps avulsion repair using a single incision with the endo-button technique. METHODS: A retrospective cohort study was performed of a single surgeon series of distal biceps repairs performed consecutively from September 2016 to September 2020. At two years, outcome measures included Oxford Elbow Score (OES), range of movement (ROM), complications and ongoing issues. RESULTS: Forty-five distal biceps tendon repairs were performed on 43 patients with a mean follow-up of 3.2 years (1.1-5.3). The average OES was 46 (11-48), and 90% of patients recovered a comparable range of movement to the contralateral side. Two patients developed re-rupture (4%) on days 0 and 9 of surgery, but there were no late re-ruptures of the repair. CONCLUSION: Short-term outcomes from distal biceps tendon repair show low complication rates, high patient satisfaction and good functional outcomes. The results would support acute surgical treatment of active, working-age, patients with distal biceps tendon ruptures.

BACKGROUND: Uncertainty remains regarding the role and long-term outcomes following uncemented reverse shoulder replacements (RSRs) in managing displaced proximal humeral fractures (PHFs). Although RSRs for trauma have traditionally undergone cemented fixation of the humeral component, there is increasing interest in uncemented RSRs. Our primary aim was to evaluate 2-year outcomes following uncemented RSR fixation for 3- and 4-part PHFs in the elderly. A secondary aim was to evaluate if timing of surgery affected outcomes. METHODS: This cohort series evaluated 2-year outcomes for 42 patients with Neer 3- and 4-part PHFs treated with uncemented RSRs between October 2016 and December 2019. Thirty-eight patients (90%) had clinical and radiologic follow-up at a minimum of 2 years. The primary outcomes compared postoperative range of movement, radiographic outcomes, and patient-reported outcome measures (PROMs). The PROMs collected included Oxford Shoulder Scores (OSSs), satisfaction scores, and the Friends and Family Test. The secondary outcome involved a subanalysis to see if outcomes were affected by treatment timing-within 2 weeks, 2-12 weeks, and >12 weeks. RESULTS: The mean age of patients was 74.1 years (range 58-89). There were 11 males and 31 females. No intraoperative fractures were sustained. There was 1 transient axillary neurapraxia, which fully resolved by 4 months. Three patients required postoperative transfusions. During the study follow-up period, no patients developed either deep infections requiring a washout or dislocation, and none underwent further surgery. At 2-year follow-up, radiologic follow-up demonstrated tuberosity union in 29 of 38 cases (76%). Eight of 38 patients (21%) demonstrated some glenoid notching (Sirveaux 1 or 2 only) on radiographic follow-up. There was no evidence of loosening. The mean OSS was 38 (range 15-48). Mean range of movement achieved at 2 years was as follows: forward flexion 122° (50°-180°), abduction 116° (46°-180°), and external rotation 25° (range 5°-60°). Eighteen patients (47%) described their result as excellent, 17 (45%) as good, and 3 (8%) as poor. When comparing the time from injury to treatment, there was no statistically significant difference in complications or radiographic outcomes between the groups. Patients had a reduced forward flexion when treated between 2 and 12 weeks compared with the other groups (P = .019). CONCLUSION: Uncemented RSR is a safe treatment option for the management of complex PHFs in the elderly. We report low complication rates, high patient satisfaction, and good outcomes at 2-year follow-up.

BACKGROUND: Given the degree of variation in clavicular morphology, 4 clavicle plating systems were examined for their congruity as superior, midshaft, anatomic clavicle (SMAC) plates in a cadaveric study. METHODS: SMAC plates from 4 manufacturers were applied to 79 dry right human clavicles. Two systems offered multiple (4) variations of plates (MP), 1 offered two variations (TP), and 1 had a single plate (SP). Two examiners applied and clamped the best-fitting plate from each system onto each of the 79 clavicles and then graded them: 1, poor fit; 2, good fit; and 3, anatomic fit. Each examiner repeated the process to assess intraobserver and interobserver reliability. The scores were averaged to produce a final score for each system for each clavicle. RESULTS: The MP systems scored the highest (32%-37% anatomic, 54%-63% good, 5%-8% poor), followed by the TP system (30% anatomic, 53% good, 17% poor), and finally the SP system (9% anatomic, 59% good, 32% poor). Of note, clavicular length significantly correlated with a higher degree of conformity in all plating systems (Spearman rank correlation P < .05 for each system). In clavicles longer than 150 mm, the MP and TP systems performed identically, with the SP system close behind. Contouring of the plate is needed in 73% of cases overall. CONCLUSION: Plating systems with multiple plate shape variations are more advantageous when dealing with smaller-sized clavicles, typically in females. However, when dealing with larger clavicles, there was no real difference.

Background Posterolateral rotatory instability of the elbow arises from damage to the lateral ulnar collateral ligament (LUCL). While various methods exist for reconstructing or repairing the LUCL's attachment to the humerus, the most effective approach remains debatable. This study aims to assess the outcomes of directly repairing the LUCL when the injury occurs at the humeral attachment. Methodology This retrospective study, conducted at the Royal Berkshire Foundation Trust NHS hospital in Reading, UK, assessed outcomes through a review of 15 patients who underwent direct repair of the lateral ulnar collateral ligament between 2017 and 2022, evaluating a range of motion, the Mayo Elbow Performance Score, and the Nestor grading system. Results This study included nine males and six females, with an average age of 38.8 years. Most LUCL injuries arose from elbow dislocation (46.7%). The average follow-up period for patients was 26 months. At the final assessment, the mean Mayo Elbow Performance Score reached 99. According to the Nestor grading system, 12 patients achieved excellent results, and three had good outcomes. On average, there was an 11.3° loss of final extension and 5° of final flexion, yet achieving a comparable pronation-supination arch to the contralateral side. Conclusion Direct repair of the LUCL for elbow posterolateral rotary instability yielded excellent outcomes, obviating ligament reconstruction. Recognized as minimally invasive, it accelerates recovery, minimizes trauma, and offers a cost-effective procedure for managing instability.
RESUMO
Introduction: The Putti-Platt procedure is a historical technique for anterior shoulder stabilization, largely abandoned because it severely restricts movement, and causes arthritis and chronic pain. Patients continue to present with these sequelae, which can be difficult to manage. Here, we present the first published subscapularis re-lengthening for the reversal of Putti-Platt. Case Report: Patient: A 47-year-old Caucasian manual worker presented 25 years post-Putti-Platt, with chronic pain and movement restriction. External rotation was 0°, abduction was 60°, and forward flexion was 80°. He was unable to swim and struggled to work. Multiple arthroscopic capsular releases had provided no benefit. Technique: The shoulder was opened through the deltopectoral approach, and a coronal Z-incision lengthening tenotomy was made in subscapularis. The tendon was lengthened by 2 cm and the repair was reinforced using a synthetic cuff augment. Results: External rotation improved to 40°, and abduction and forward flexion to 170°. Pain resolved almost completely; Oxford Shoulder Score at 2-year follow-up was 43 (22 pre-operative). The patient returned to normal activity and reported complete satisfaction. Conclusion: This is the first application of subscapularis lengthening to Putti-Platt reversal. Two-year outcomes were excellent, demonstrating potential for significant benefit. Although presentations like this one are rare, our results support the potential of subscapularis lengthening (with synthetic augmentation) in the management of stiffness resistant to conventional treatment after Putti-Platt procedure.
RESUMO
BACKGROUND: Multiple non-arthroplasty surgical techniques are described for the management of large and massive irreparable rotator cuff tears. There is currently no consensus on the best management strategy. Our aim was to compare clinical outcomes following arthroscopic debridement, arthroscopic partial cuff repair, superior capsule reconstruction, balloon spacers or graft interposition for the management of large and massive irreparable rotator cuff tears. METHODS: A comprehensive search was performed of the following databases: Medline, Embase, CINAHL and Cochrane Database of Systematic Reviews. Data were extracted from relevant studies published since January 2000 according to the pre-specified inclusion criteria. The primary outcome was the post-operative improvement in shoulder scores. Meta-analysis of the primary outcome was performed. Secondary outcomes included retear rates and complications. RESULTS: Eighty-two studies were included reporting the outcomes of 2790 shoulders. Fifty-one studies were included in the meta-analysis of the primary outcome. The definition of an irreparable tear varied. All procedures resulted in improved shoulder scores at early follow-up. Shoulder scores declined after 2 years following balloon spacers, arthroscopic debridement and partial cuff repair. High retear rates were seen with partial cuff repairs (45%), graft interposition (21%) and superior capsule reconstruction (21%). CONCLUSIONS: Large initial improvements in shoulder scores were demonstrated for all techniques despite high retear rates for reconstructive procedures. Shoulder scores may decline at mid- to long-term follow-up.

BACKGROUND: Scapula fractures are uncommon in sports and are poorly understood in this patient group. PURPOSE: To report on scapula fractures in contact and collision athletes and assess the injury patterns of different mechanisms of injury. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective case series was performed of all sports-related scapula fractures treated at a single institution between 2007 and 2015. The mechanisms of injury were divided into direct lateral impact, fall onto an outstretched arm, or abduction/external rotation. RESULTS: A total of 11 patients were identified: 9 professional rugby players, 1 professional soccer player, and 1 amateur soccer player. The mean age was 28 years (range, 18-35 years). The mean return to play was 127 days in those treated nonoperatively and 163 days in those treated operatively. A direct impact mechanism occurred in 7 patients, all of whom sustained glenoid neck and body fractures and were treated nonoperatively. Two rugby players had a concomitant suprascapular nerve injury. An outstretched arm mechanism occurred in 2 cases, leading to posterior and inferior glenoid fractures. Both patients were treated operatively. An abduction/external rotation mechanism occurred in 2 cases, resulting in an anteroinferior and an anterior glenoid rim fracture. One case was treated operatively and the other was treated nonoperatively. Of those with glenoid fractures, 75% were not visible on plain radiographs and required further imaging. CONCLUSION: Scapula fractures acquired in sports are a serious injury with a prolonged recovery period. The mechanism of injury can help predict the injury pattern and highlight the need for further imaging. There is a high association with suprascapular nerve injuries.
RESUMO
The management of glenoid bone loss is a major challenge in both complex primary and revision arthroplasty surgery. To deal with this problem, a number of techniques have been advocated, although there has been no previous systematic review of the literature. In the present review, we have attempted to identify a coherent strategy for addressing this problem, taking into account the degree of bone loss, the advantages and limits of standard implants, bone reconstruction techniques and the use of customized prostheses.
RESUMO
BACKGROUND: The accuracy of reconstruction is thought to impact on functional outcome following glenohumeral joint arthroplasty. The objective of this study was to define an area of minimal anatomic variation at the cartilage/metaphyseal interface of the proximal humerus to optimize the osteotomy of the humeral head, enabling accurate reconstruction with a prosthetic component. METHODS: Hand held digitization and 3D surface laser scanning techniques were used to digitize 24 cadaveric arms and determine the normal geometry. Each humeral head was then examined to identify the most consistent anatomical landmarks for the ideal osteotomy plane to optimize humeral component positioning. FINDINGS: The novel, posterior referencing, osteotomy resulted in a mean increase in retroversion of only 0.4° when compared to the original geometry. A traditional anterior referencing osteotomy, by comparison, produced a mean increase in retroversion of 11°. In addition, the novel osteotomy only increased axial diameter by 0.71mm and head height by 0.02mm compared to an anterior referencing osteotomy (3.0mm and 2.7mm respectively). INTERPRETATION: The traditional osteotomy, referencing the anterior border of the cartilage/metaphyseal interface potentially resulted in an increase in prosthetic head size and retroversion. The novel osteotomy, referencing from the posterior cartilage/metaphyseal interface enabled a more accurate recovery of head geometry. Importantly, the increase in retroversion created by the traditional osteotomy was not replicated with the novel technique. Referencing from the posterior cartilage/metaphyseal interface produced a more reliable osteotomy, more closely matching the original humeral geometry. LEVEL OF EVIDENCE: Basic Science, Anatomic study, Computer model.

Giant inguinal herniae pose a surgical challenge, though not uncommon in the developing world they are a rare presentation in the UK. We present a patient with cardiac disease who presented with a giant inguino-scrotal hernia complicated by a bleeding scrotal ulcer. We describe his medical management and the surgical repair of the hernia and refashioning of his scrotum.
RESUMO
Formation of the trochlear nerve within the anterior hindbrain provides a model system to study a simple axonal projection within the vertebrate central nervous system. We show that trochlear motor neurons are born within the isthmic organiser and also immediately posterior to it in anterior rhombomere 1. Axons of the most anterior cells follow a dorsal projection, which circumnavigates the isthmus, while those of more posterior trochlear neurons project anterodorsally to enter the isthmus. Once within the isthmus, axons form large fascicles that extend to a dorsal exit point. We investigated the possibility that the projection of trochlear axons towards the isthmus and their subsequent growth within that tissue might depend upon chemoattraction. We demonstrate that both isthmic tissue and Fgf8 protein are attractants for trochlear axons in vitro, while ectopic Fgf8 causes turning of these axons away from their normal routes in vivo. Both inhibition of FGF receptor activation and inhibition of Fgf8 function in vitro affect formation of the trochlear projection within explants in a manner consistent with a guidance function of Fgf8 during trochlear axon navigation.
