1. Maximum motor nerve conduction velocities were determined under standard conditions for the median and ulnar nerves in the right forearm in males: (a) from the general population, (b) from a subnormality hospital, and (c) in males with the XYY sex chromosome abnormality. Distal latencies for these nerves were also measured. 2. No significant differences in maximum peripheral motor nerve cond...

Martin-Gruber anastomosis (MGA) is a well described anostomosis between the median and ulnar nerves in various levels. MGA involves axons leaving either the main trunk of median nerve or the anterior interosseous nerve, crossing through the forearm to join the ulnar nerve and it’s insidence was reported as %10-40. The incidence of this anastomosis is important so that it can cause confusion in ...

There have been reports of ulnar nerve compression due to anatomic variations at Guyon’s canal. Knowledge certain canal may help hand surgeons identify possible unconventional sites the nerve. We present a case report patient with an aberrant palmaris brevis muscle belly that was found cross over proximal aspect tunnel neurovascular bundle potentially causing symptoms. Surgical interventions re...

OBJECTIVE To determine the diagnostic cutoff values of ultrasonographic measurements in ulnar neuropathy at the elbow (UNE). METHODS Twenty-five elbows of 23 patients (9 females, 16 males) diagnosed with UNE and 30 elbows of 30 healthy controls (15 females, 15 males) were included in our study. The ulnar nerve cross-sectional area (CSA) was measured at the Guyon canal, midforearm, and maximal...

Elbow fractures are not uncommon in children, and some are associated with neurovascular injuries. Having a nerve injury in an elbow fracture without dislocation is rare and was not described in the literature. Here, we have reported probably the first case of an ulnar nerve injury in an elbow fracture without dislocation. A 9-year-old female presented to the emergency department after falling ...

BACKGROUND The limited nerve sources available for the reconstruction and restoration of upper extremity function is the biggest obstacle in the treatment of brachial plexus injury (BPI). We used part of a transplanted vascularized ulnar nerve as a motor source of a free muscle graft. CASE PRESENTATION A 21-year-old man with a left total brachial plexus injury had received surgical intercosta...

The peripheral distribution of the fibre content of individual ulnar nerve fascicles supplying skin and muscles of the hand in human volunteers was indirectly mapped by tracing the fields of projected sensation evoked by intraneural electrical microstimulation (INMS) and by tracing receptive fields delineated through intraneural recording of afferent impulse activity elicited by natural stimula...
