Proprioception is one's overall sense of the relative positions and movements of the various parts of one's body. The primary somatosensory cortex (SI) is involved in generating the proprioception by receiving peripheral sensory inputs from both cutaneous and muscle afferents. In particular, area 3a receives input from muscle afferents and areas 3b and 1 from cutaneous afferents. However, segre...

BACKGROUND Today, humerus nails have become the surgical method of choice in the treatment of humerus shaft fractures. Whether or not the radial nerve should be intraoperatively examined by default in case of primary paresis is currently under discussion. PATIENTS AND METHODS Clinical findings from 38 patients with humeral shaft fractures surgically treated with unreamed humerus nail (UHN) at...

Involvement of Radial Nerve in leprosy is not very common. Only 0.2% of Radial Nerve deformities is observed. There are various procedure to correct the wrist function. We have analyzed various motor units to correct the wrist function as per the patient requirement.

Posterior interosseous nerve palsy caused by a ganglion is not common and most previous patients were treated with excisional surgery. We treated a case conservatively with needle aspiration using ultrasonography, after a nerve conduction study. A 77-year-old man presented with impaired active finger extension of the left metacarpophalangeal joints. The nerve conduction study revealed conductio...

Peripheral artery cannulation is a common procedure but can sometimes be difficult. Our goal was to determine if a median nerve block would increase the diameter and flow of the radial artery. Radial artery diameter and peak velocity was measured using a SonoSite Ultrasound System. Using ultrasound guidance, a median nerve block was performed with lidocaine. Subsequent measurements of the radia...

Background:  The purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   Methods:  This is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. The average time between implantation and removal was 23 month...

Distal humerus fractures are uncommon, comprising 2% of all fractures and a third of all humerus fractures. Open fractures, comminuted fractures and fracture dislocation of the elbow are often accompanied by severe soft tissue damage. External fixation of the humerus is indicated when severe soft tissue damage or the presence of infection warrants initial alternative immobilisation of the fract...

BACKGROUND The combination of an elbow dislocation, a radial head fracture, and a coronoid process fracture is known as "terrible triad" injury of the elbow. This injury is one of the most challenging injuries of the musculoskeletal system and almost always causes instability of the elbow. The use of an adjuvant hinged external fixator in such injuries is still debated. CASE PRESENTATION In t...

BACKGROUND The posterior interosseous nerve (PIN) can be difficult to locate within the radial tunnel. The deep branch of the radial nerve (DBRN) enters the supinator muscle after passing under the arcade of Fröhse. It courses through the superficial portion of the supinator muscle to exit distally as the PIN. Anatomic landmarks could facilitate diagnosis and treatment of radial tunnel syndrome...

A technique for recording evoked sensory potentials from the radial nerve has already been reported by us (Downie and Scott, 1964). This technique, although reliable, is time consuming and occasionally difficult and the amplitude of potentials may be as low as 1 to 2 microvolts. The purpose of this communication is to describe a simpler technique by which potentials of greater amplitude can be ...
