Free gracilis muscle transfer with ulnar nerve neurotization for elbow flexion restoration.

PURPOSE: In upper and chronic brachial plexus injuries for which neurological surgery is not a good treatment option, one possibility for gaining elbow flexion is free functional muscle transfer. The primary aim of our study was to evaluate the elbow flexion gain achieved by free gracilis muscle transfer with partial ulnar nerve neurotization. METHODS: This surgery was performed in 21 patients with upper and chronic (> 12 months) brachial plexus injuries. The level of injury, patient age, the time between trauma and surgery, the affected side, and the aetiology of the lesion were recorded. The primary outcome evaluated was elbow flexion muscle strength, which was measured using the British Medical Research Council (BMRC) scale, in patients with a minimum follow-up period of 12 months. The criterion used to classify elbow flexion as good was a grade of M4 or higher. RESULTS: An M4 elbow flexion strength gain was observed in 61.9% of the patients. A gain of M2 or higher was observed in 95.2% of the patients. The mean range of active motion was 77° (range 10 minimum-110 maximum). CONCLUSION: In patients with upper and chronic brachial plexus injuries, free gracilis muscle transfer with ulnar nerve neurotization yields a satisfactory gain in elbow flexion strength and is therefore a good treatment option.

Undescended testes: What general practitioners need to know

BACKGROUND: Undescended testis (UDT) is a common condition, and parents often primarily present to general practitioners. Management in a timely fashion may reduce the risk of malignancy and infertility OBJECTIVES: The aim of this article is to summarise the key points of assessment and management of UDT in the primary care setting. By reviewing key definitions, such as undescended, retractile, ectopic and ascending testes, we aim to provide updated information for the ongoing management of these conditions. DISCUSSION: The exact pathophysiology of UDT is still an area of ongoing research, and there remains much controversy regarding the exact mechanisms leading to congenital and acquired UDT. Current evidence does not support the use of ultrasonography prior to referral. Hormone therapy has shown no significant benefit, and surgery remains the treatment of choice.

Lower Trapezius Transfer for Patients With Brachial Plexus Injury.

BACKGROUND: Brachial plexus injury is a complex entity that often results in partial recovery. Most studies to date have focused on improving shoulder abduction. However, a recent technique has been outlined-one that transfers the lower trapezius to improve the external rotation of the shoulder. The primary objective of this study was to evaluate the gains in external rotation of the shoulder in patients who have undergone transfer of the lower trapezius; secondarily, we assessed the range of motion in the elbow and shoulder joints, as well as the muscle strength and quality of life. METHODS: This article presents a prospective cohort study of 10 patients who underwent transfer of the lower trapezius. During the preoperative period and at 6 months after the operation, both active and passive goniometric measurements were assessed, as were muscle strength, Mallet's classification, and patients' responses to the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: External rotation exhibited an improvement of 17° in the active range of motion and 14° the passive range, which was not statistically significant. Flexion and active abduction of the shoulder, as well as the responses to the DASH, showed positive results. The Mallet's classification and muscle strength measurement results were not significant. CONCLUSIONS: The procedure might be an alternative for restoration of shoulder function and glenohumeral stabilization and mainly to improve quality of life. However, additional studies are required to define and refine this surgical technique.
