Scapular winging: anatomical review, diagnosis, and treatments

Scapular winging is a rare debilitating condition that leads to limited functional activity of the upper extremity. It is the result of numerous causes, including traumatic, iatrogenic, and idiopathic processes that most often result in nerve injury and paralysis of either the serratus anterior, trapezius, or rhomboid muscles. Diagnosis is easily made upon visible inspection of the scapula, with serratus anterior paralysis resulting in medial winging of the scapula. This is in contrast to the lateral winging generated by trapezius and rhomboid paralysis. Most cases of serratus anterior paralysis spontaneously resolve within 24 months, while conservative treatment of trapezius paralysis is less effective. A conservative course of treatment is usually followed for rhomboid paralysis. To allow time for spontaneous recovery, a 6–24 month course of conservative treatment is often recommended, after which if there is no recovery, patients become candidates for corrective surgery

Medieval injuries: Skeletal trauma as an indicator of past living conditions and hazard risk in Cambridge, England

Abstract: Objective: To explore how medieval living conditions, occupation, and an individual's role within society impacted their risk of skeletal trauma. Materials: The skeletal remains of 314 individuals from medieval Cambridge that were buried in the parish cemetery of All Saints by the Castle (n = 84), the Augustinian friary (n = 75), and the cemetery of the Hospital of St John the Evangelist (n = 155) were analyzed. Methods: Macroscopic examination and plain radiographs were used to classify fracture type. The causative mechanisms and forces applied to a bone were inferred based on fracture morphology. Results: The skeletal trauma observed represents accidental injuries, likely sustained through occupational or everyday activities, and violence. The highest prevalence rate was observed on the individuals buried at All Saints by the Castle (44%, n = 37/84), and the lowest was seen at the Hospital of St John (27%, n = 42/155). Fractures were more prevalent in males (40%, n = 57/143) than females (26%, n = 25/95). Conclusions: Skeletal trauma was highest in All Saints parish burial ground, indicating that the poor, whether working urban or rurally, had the highest risk of injury. The pattern and types of fractures observed suggests that males experienced more severe traumatic events than females. However, females that were routinely involved in manual labor were also at increased risk of injury. Significance: This article enhances our understanding of how traumatic injuries differed by age, sex, and burial locations in the medieval period. Further research: Additional comparative studies in different geographical regions are needed to determine how representative these findings are

Microneurolysis and decompression of long thoracic nerve injury are effective in reversing scapular winging: Long-term results in 50 cases

<p>Abstract</p> <p>Background</p> <p>Long thoracic nerve injury leading to scapular winging is common, often caused by closed trauma through compression, stretching, traction, direct extrinsic force, penetrating injury, or neuritides such as Parsonage-Turner syndrome. We undertook the largest series of long thoracic nerve decompression and neurolysis yet reported to demonstrate the usefulness of long thoracic nerve decompression.</p> <p>Methods</p> <p>Winging was bilateral in 3 of the 47 patients (26 male, 21 female), yielding a total of 50 procedures. The mean age of the patients was 33.4 years, ranging from 24–57. Causation included heavy weight-lifting (31 patients), repetitive throwing (5 patients), deep massage (2 patients), repetitive overhead movement (1 patient), direct trauma (1 patient), motor bike accident (1 patient), and idiopathic causes (9 patients). Decompression and microneurolysis of the long thoracic nerve were performed in the supraclavicular space. Follow-up (average of 25.7 months) consisted of physical examination and phone conversations. The degree of winging was measured by the operating surgeon (RKN). Patients also answered questions covering 11 quality-of-life facets spanning four domains of the World Health Organization Quality of Life questionnaire.</p> <p>Results</p> <p>Thoracic nerve decompression and neurolysis improved scapular winging in 49 (98%) of the 50 cases, producing "good" or "excellent" results in 46 cases (92%). At least some improvement occurred in 98% of cases that were less than 10 years old. Pain reduction through surgery was good or excellent in 43 (86%) cases. Shoulder instability affected 21 patients preoperatively and persisted in 5 of these patients after surgery, even in the 5 patients with persistent instability who experienced some relief from the winging itself.</p> <p>Conclusion</p> <p>Surgical decompression and neurolysis of the long thoracic nerve significantly improve scapular winging in appropriate patients, for whom these techniques should be considered a primary modality of functional restoration.</p
