The superficial branch of the radial nerve (SBRN) is highly vulnerable to trauma and iatrogenic injury. This study aimed to map the course of the SBRN in the context of surgical approaches and identify a safe area of incision for de Quervain's tenosynovitis. Twenty-five forearms were dissected. The SBRN emerged from under brachioradialis by a mean of 8.31 cm proximal to the radial styloid (RS),...

ntrapment of the radial nerve, specifically the deep branch of the radial nerve (DBRN) in the arcade of Frohse, was first described in 1963.1 Prolonged entrapment may lead to a constellation of symptoms described in posterior interosseous nerve (PIN) paralysis.2 Reported attempts at diagnosis using imaging have mostly involved magnetic resonance imaging (MRI), with a limited number of studies c...

The ulnar dorsal aspect of the hand is predominantly innervated by the dorsal ulnar cutaneous nerve with variable input from the superficial radial cutaneous nerve. This cross innervation can cause difficulty in interpreting low amplitude sensory nerve action potential for the dorsal ulnar cutaneous nerve particularly when facing suspected ulnar neuropathyat the elbow. In three subjects with lo...

BACKGROUND A 55 year old gentleman presented with tardy posterior interosseous nerve palsy associated with radial head fracture. CASE PRESENTATION The patient developed symptoms of wrist drop 24 hours after the injury whilst awaiting surgery for his Mason III radial head fracture. EMG studies confirmed the presence of a posterior interosseous nerve lesion. Open exploration revealed oedematous...

A patient with a radial nerve palsy which persisted nine months after a diaphyseal fracture of the humerus was referred to our department. Radiographs and ultrasound examination showed that the radial nerve was transected and partially entrapped in the fracture callus. This double injury was confirmed and was repaired during subsequent surgical treatment. We report this rare case of combined pr...

Background. Due to anatomical proximity to bone, the radial nerve is the most frequently injured major nerve of the upper extremity, frequently secondary to fractures (Li et al. (2013)). We describe an incidence when a branch of the radial nerve is injured as a result of a thermal injury. Observation. Radial nerve injury can occur anywhere along the anatomical course with varied etiologies, but...

BACKGROUND Due to the anatomical nature of the radial nerve, dissection and attainment of an adequate operative field in mid to distal humerus fracture is dangerous and limited. We devised a combined anterolateral and lateral approach that ensures protection of the radial nerve. This is achieved by performing bimodal dissection of the proximal humerus anteriorly and the distal humerus laterally...
