Background: Vascular compression is an extremely rare cause of mononeuropathy and compression of selective tibial nerve branches is an additionally a rare finding and makes diagnosis difficult. Case Description: Here within, we describe the case of a 41-year-old male who presented with isolated mononeuropathy of the medial gastrocnemius (MG) branch of the tibial nerve presented as persistent fasciculations and atrophy. After electromyography and clinical evaluation, surgical exploration was recommended. A vascular bundle was found to be compressing the MG branch of the tibial nerve and thus was ligated to decompress the nerve. Postoperatively, all fasciculations improved and muscle atrophied improved. Conclusion: Vascular compression resulting in mononeuropathy of the peripheral nerves is a rare clinical entity. Clinicians should include these etiologies on their differential when considering surgical exploration of mononeuropathies.

Penile Fournier’s gangrene (FG) is very rare clinical entity, which is also known as penile necrotizing fasciitis or wet gangrene of the penis. It is associated with increased morbidity and mortality and in the majority of the described cases it affects not only penis but also the adjacent organs and tissues (e.g., bladder, muscles, rectum, testis, and scrotum). We report a rare case of a previously healthy 68-year-old male, who presented with acute isolated penile Fournier’s gangrene. Pus culture was identified with pathogens Enterococcus faecalis, Streptococcus gordonii, and Prevotella melaninogenica. Prompt surgical exploration, fluid resuscitation, antibiotic treatment, and diligent postoperative care are the cornerstone in the successful treatment of this emergency with high mortality.

Medial Gastrocnemius Muscle

The aim of the study was to determine whether increased motoneuron activity induced by treadmill walking would alter the extent of motoneuron sprouting in the partially denervated rat medial gastrocnemius muscle. An extensive partial denervation was effected by unilateral section of the L5 ventral root, and it is very likely that all units remaining in the medial gastrocnemius were used in treadmill walking. Rats were trained for 1.5 h/day and after 14 days were walking at least 1 km/day. Motor unit characteristics were determined 24 days after the partial denervation and were compared with units from partially denervated control (PDC) animals and with units from normal (control) animals. In PDC rats, force developed by slow, fast fatigue-resistant, and fast intermediate-fatigable motor units increased substantially compared with control animals; that of fast-fatigable units did not increase. In partially denervated exercised animals, force developed by slow and fast-fatigue-resistant units showed no further increase, but fast-intermediate- and fast-fatigable units showed significant increases compared with those in PDC animals. The changes in force were closely paralleled by changes in innervation ratios. We concluded that neuronal activity is an important factor in determining the rate of motoneuron sprouting.

Abstract BACKGROUND: Lower-limb function is severely impaired after sacral plexus nerve injury. Nerve transfer is a useful reconstructive technique for proximal nerve injuries. OBJECTIVE: To investigate the clinical effectiveness and safety of transferring the ipsilateral obturator nerve to the branch of the tibial nerve innervating the medial head of the gastrocnemius muscle to recover knee and ankle flexion. METHODS: From 2007 to 2011, 5 patients with sacral plexus nerve injury underwent ipsilateral obturator nerve transfer as part of a strategy for surgical reconstruction of their plexuses. The mean patient age was 31.4 years (range, 19-45 years), and the mean interval from injury to surgery was 5.8 months (range, 3-8 months). The anterior branch of the obturator nerve was coapted to the branch of the tibial nerve innervating the medial head of the gastrocnemius muscle by autogenous nerve grafting. RESULTS: Patient follow-up ranged from 24 to 38 months. There were no complications related to the surgery. Three patients recovered to Medical Research Council grade 3 or better in the medial head of the gastrocnemius muscle. Thigh adduction function was not affected in any patient. CONCLUSION: Knee and ankle flexion can be achieved by transferring the anterior branch of the obturator nerve to the branch of the tibial nerve innervating the medial head of the gastrocnemius muscle, which is useful for balance. This procedure can be used as a new method for treating sacral plexus nerve injury.
