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.

Arnold-Chiari Malformation Type I Presenting With Bilateral Scapular Winging.

Department of Neurology, Jose R. Reyes Memorial Medical Center, Manila, PHL.
Bilateral scapular winging is a rare and atypical manifestation of Arnold-Chiari malformation type 1 (ACM1). We report a case of ACM with extensive syrinx formation, presenting with progressive bilateral proximal upper extremity weakness, bilateral scapular winging, and segmental hypesthesia and reduced thermesthesia over the bilateral C2-C8 dermatomal levels. The patient was successfully treated with surgical decompression and syringosubarachnoid shunting.

The long thoracic nerve's (LTN) superficial location on the chest wall renders it vulnerable to iatrogenic injury. Plastic surgeons' gender-affirming mastectomy volumes are rapidly increasing. This operation involves lateral chest contouring placing the distal LTN at risk of injury along the chest wall.

Columbia University, Department of Biomedical Engineering, New York, NY, USA.
Objectives: Moire Topography (MT) is a non-invasive technique that uses patterned light projection and has been used to qualitatively characterize scapular winging. The purpose of the present study was to quantitatively characterize scapular winging using a novel method of MT.

Article Synopsis
- The study investigates the effectiveness of partial pectoralis major transfer and modified Eden-Lange/Triple Tendon Transfer in improving pain and shoulder function for individuals with specific muscle deficiencies.
- A review of 11 military patients showed significant improvements in shoulder-related outcome scores after surgery, with many able to return to active duty.
- The findings suggest these surgical procedures are beneficial for patients with high physical demands, particularly in military settings.
Background: Injuries to the long thoracic nerve (LTN) and upper trunk of the brachial plexus (UTBP) can occur simultaneously and cause scapular winging and shoulder instability. The literature has not documented the concurrent occurrence of UTBP and LTN injuries in these patients. We show an upper trunk injury in patients whose preoperative electromyography (EMG) did not show injury to the UTBP.
