Neurolysis of the Long Thoracic Nerve for Scapular Winging due to Isolated Serratus Anterior Palsy: Early and Midterm Results in 29 Patients.

Objective: This study aimed to report our surgical outcomes of thoracic long thoracic nerve (LTN) decompression in patients with isolated LTN palsy, using a clinical scoring system designed to facilitate the grading of scapular winging severity. Methods: This was a retrospective review of patients who had undergone decompression and neurolysis of the LTN for scapular winging. Each patient underwent needle electromyography of the serratus anterior for confirmation of diagnosis and were refractory to a minimum of 6 months of nonoperative management. Preoperatively and at final follow-up, shoulder range of motion and the Wrightington Winging Score (WWS) was used to objectively grade the dynamic and static components of winging. Results: Between 2014 and 2020, 29 patients who underwent thoracic neurolysis for scapular winging were analyzed. These were 16 males and 13 females with a mean age of 37 years. The injury mechanism was due to trauma in 19 cases and neuralgic amyotrophy in 10. The median duration between winging onset and surgery was 30 months. There were significant improvements in mean active shoulder abduction and forward flexion. Winging was noticeably improved in 22 patients. At presentation, the median WWS was 3, which improved to 1 at final follow-up. Conclusion: In patients with isolated LTN palsy causing persistent scapular winging which is not responsive to conservative treatment, neurolysis of the thoracic portion of the LTN can be considered. Level of Evidence: IV.

Prognosis After Arthroscopic Superior Medial Scapuloplasty for Snapping Scapula Syndrome Improves After a Transient Beneficial Response With an Ultrasound-Guided Subscapular Cortisone Injection.

PURPOSE: To evaluate the prognostic value of an ultrasound-guided subscapular local anesthetic and cortisone injection in a consecutive series of patients who underwent an arthroscopic superior medial scapuloplasty for snapping scapula syndrome (SSS) and had been refractory to conservative treatment. METHODS: We undertook an arthroscopic superior medial scapuloplasty on patients with a clinical diagnosis of SSS who had failed a structured physiotherapy program and had either gained a good response or no to minimal response to preoperative ultrasound-guided subscapular local anesthetic and cortisone injection. The patients were assessed preoperatively and at final follow-up with the QuickDASH and Constant scores, and their pain was assessed with a visual analog scale (VAS). RESULTS: Between January 2009 and December 2016, 47 patients were included in the study, with a minimal follow-up of 2 years. There were 29 female and 18 male patients, and the mean age at the time of surgery was 27.4 years (range 15 to 61). Forty-two patients were available at final follow-up. There were 31 patients in the good response group and 11 patients in the no to minimal response group. For all patients, the mean time to follow-up was 41.8 months (range 24 to 108). There was a significant improvement after surgery in the mean QuickDASH score (from 39 to 20, P < .001) (minimal clinically important difference [MCID] 15.91) , Constant score (from 57 to 87, P < .001) (MCID 10.4), and VAS (from 6 to 2, P < .001) (MCID 3). For the good response group, there was a significant improvement after surgery in the mean QuickDASH score (from 38 to 18, P < .001) (MCID 15.91), the Constant score (from 57 to 89) (MCID 10.4), and the VAS (from 6 to 2, P < .001) (MCID 3). For the no to minimal response group, there was a significant improvement after surgery in the mean QuickDASH score (from 42 to 24, P < .01) (MCID 15.91), the Constant score (from 58 to 80, P < .002) (MCID 10.4), and the VAS (from 6 to 2, P < .01) (MCID 3). The difference in postoperative improvement of the QuickDASH and Constant scores between the good response and the no to minimal response groups was statistically significant (P < .05). CONCLUSION: The results of this study suggest that arthroscopic scapuloplasty can lead to a significant improvement in pain and function in all patients with a clinical diagnosis of snapping scapula syndrome refractory to conservative treatment. Patients who gained a good transient response to a preoperative ultrasound-guided subscapular cortisone injection obtained a significantly better recovery than those who did not. A preoperative ultrasound-guided subscapular cortisone injection appeared to be of prognostic value.

Outcomes following surgical management of complex terrible triad injuries of the elbow: a single surgeon case series.

BACKGROUND: Terrible triad injuries of the elbow are complex injuries to treat and we report our outcomes following surgical management. METHODS: Twenty-two consecutive patients who underwent fixation of terrible triad injuries between 2007 and 2012 were identified. Clinical outcomes were assessed by examination, visual analogue scores (VAS), Oxford Elbow Score (OES), Mayo Elbow Performance Index (MEPI) and QuickDash score (QD). RESULTS: The mean age of patients was 47 years, with a mean follow-up of 32 months. All patients underwent lateral ligament repair, with additional medial ligament repair in four cases. Thirteen patients required repair of the coronoid and 18 patients required surgery to the radial head. The mean flexion-extension arc was 113°, with mean prono-supination of 136°. The functional elbow scores revealed good outcomes in the majority (mean OES of 37, MEPI of 79 and QD of 21). The overall complication rate was 41%. In total, 23% required reoperation, with one patient requiring fasciotomy for acute compartment syndrome and four requiring subsequent removal of metalwork as a result of stiffness. CONCLUSIONS: Recognition of this complex injury pattern and appropriate restoration of the joint stability are the prerequisites. Systematic surgical approach is effective and can provide both stability and good function, in most cases.

Simple elbow dislocation.

The elbow is the second most commonly dislocated major joint in adults. Good long-term outcomes have been reported after non-operative management; however, a small proportion (<10%) of patients have a poor outcome and some do require surgical intervention. A review of the anatomy, pathoanatomy, management and outcomes of simple elbow dislocations is presented. Emphasis is placed on emerging concepts regarding the soft tissue injury, the stabilising structures that are injured, the sequence and mechanism of injury and the relationship to elbow stability. The benefits of nonsurgical and surgical management are discussed and a treatment algorithm based on the pathoanatomy is proposed.

Hip arthroscopy: evolution, current practice and future developments.

Arthroscopic examination and treatment is an ever-increasing part of modern orthopaedic practice in this age of minimally invasive surgery. Arthroscopic procedures have been widespread in surgery of the knee and the shoulder for many years; however, the hip until relatively recently, has been largely neglected. Even now hip arthroscopy is not widely available; this may be due to the complexity of the procedure, the requirement of specialist equipment and a reportedly long learning curve. On the other hand, it has gone through a period of rapid growth over the last decade and is being performed in large numbers routinely in some centres around the world. Hip arthroscopy now provides excellent visualisation of not only the articular surfaces of the hip joint but also of the peritrochanteric or extra-articular space around the hip. Pathology of both the femoral head and the acetabulum along with the soft tissues of the hip, namely the ligamentum teres, the acetabular labrum, the synovial folds and synovium, is readily diagnosed. Modern techniques provide therapeutic options for a myriad of conditions and allow modulation of pathological processes early. Additionally hip arthroscopy is a relatively safe procedure with few complications and contraindications. However, the key to good outcomes is in the careful selection of patients and meticulous surgical technique. The aim of this review is to bring the reader up to date with an overview of the evolution of arthroscopy of the hip, review the current practice and explore possible future developments.

Delayed presentation of Subclavian venous thrombosis following undisplaced clavicle fracture.

Medial clavicle fractures are uncommon, accounting for approximately 5 percent of all clavicle fractures. Vascular injuries are uncommon but are recognised as either an immediate complication due to transection of the vessel by the displaced fracture, or as a late complication, secondary to compression from abundant callus formation. We present an unusual case of positional venous insufficiency in the upper limb as an immediate complication of a closed, minimally displaced clavicle fracture, with secondary subclavian venous thrombosis formation eleven days following the injury.

Skewing of pretransplant anti-HLA class I antibodies of immunoglobulin G isotype solely toward immunoglobulin G1 subclass is associated with poorer renal allograft survival.

Sensitized patients with lymphocytotoxic immunoglobulin (Ig)G anti-human leukocyte antigen (HLA) antibodies have an increased risk of rejection and poorer graft survival. Little is known, however, about the correlation between IgG antibody subclass and clinical outcomes. We identified 20 sensitized renal transplant recipients (panel reactive antibody >15%), all of whom had anti-HLA class I antibodies of an IgG isotype with known specificity before transplantation but who received a crossmatch negative graft. We analyzed the degree of skewing solely toward IgG1 (n=11) or to other IgG subclasses with or without IgG1 (n=9) and correlated these findings with graft survival. At last follow-up (median follow-up 28 months), 6 of 11 patients (55%) with anti-HLA antibodies skewed toward IgG1 had lost their grafts compared with 0 of 9 patients (0%) with anti-HLA antibodies not skewed toward IgG1 (P =0.01 log-rank test). Anti-HLA antibodies of an IgG1 subclass may be a novel marker predicting poor graft outcome.
