Article Abstract
Purpose: To compare the functional outcomes of nerve grafts and nerve transfers in the management of isolated musculocutaneous nerve (MCN) injuries.
Methods: We performed a retrospective case-control study of isolated MCN injury managed at a tertiary care center. The study group was composed of 12 patients managed with double nerve transfer whereas the 8 patients in the grafted group constituted the control group.
Results: In the study group, stab and missile injuries constituted most cases with a denervation period ranging between 3 and 9 months. Eleven patients in this group experienced a full range of active elbow flexion whereas one had antigravity flexion of 120°. Electromyography revealed the first sign of reinnervation of biceps at 10 ± 2 weeks, compared with 20 ± 2 weeks in the grafted group. The overall trend was for patients in the study group to have earlier return of active elbow flexion and better restoration of elbow flexion strength and range of (presumably active) elbow motion than those treated with grafting, although none of these measures reached statistical significance.
Conclusions: We found that distal nerve transfer was a superior method of managing isolated MCN injury compared with conventional nerve grafting.

The choice of a donor nerve to innervate a free gracilis muscle transfer (FMGT) is more complicated in patients with a history of previous facial paralysis surgeries. This case report describes the use of the deep temporal nerve to successfully power a FMGT in a nerve-depleted patient.

Background: Poor recovery of active glenohumeral external rotation (aGHER) after brachial plexus birth injury (BPBI) is common. Late spinal accessory nerve to infraspinatus motor branch (SAN-IS) transfer has been reported as effective. We investigated its efficacy in children over 4 years with BPBI.

Background: Loss of breast sensation following mastectomy and reconstruction significantly impacts quality of life, influencing body image, intimacy, and overall emotional well-being. Despite advances in reconstructive techniques, sensory outcomes remain inconsistent, limiting broader clinical adoption of reinnervation strategies. This educational review synthesizes the current scope of sensory restoration in breast reconstruction, examining approaches to reinnervation, sensory outcome measures, and management of patient expectations.

Persistent overactivation of the renal sympathetic nervous system drives kidney inflammation and fibrosis. Macrophages contribute to fibrogenesis by secreting various pro-fibrogenic mediators. However, whether the sympathetic nervous system regulates renal fibrosis by modulating macrophage-fibroblast interaction remains unclear.

Stroke and traumatic brain injury lead to upper motor neuron syndrome, which is characterized by muscle spasticity or paresis of varying severity depending on the lesion's location and extent. Current treatments are mostly symptomatic with limited efficacy and significant side effects. Nerve transfer techniques, such as the contralateral L4 ventral root transfer in animal models and C7 root transfer in both animal and clinical studies, have been shown to reduce spasticity and improve function in upper motor neuron syndrome; however, they lack selectivity.
