Radial nerve palsy following traumatic humeral diaphyseal fractures occurs uncommonly. Most recover with good outcome. However the cases with poor outcome or recovery will have tendon transfers to regain the lost functions. Various tendon transfer methods and choices are available in literatures citing acceptable to good results. We report a case of radial nerve transection secondary to a closed traumatic diaphyseal fracture of the humerus which did not improve despite the repair. As many conventional technique produce asynergistic muscle action with secondary post-transfer deformity, thus we had resorted to tendon transfer procedure using an unconventional donor and recipient tendons yielding good results. This new combination of tendon transfers was invented involves better dynamic correlation of synergistic muscles action and produces good outcome and hand function.

The supracondylar humerus fracture (SCHF) in children is common and can be complicated with nerve injury either primarily immediate post-trauma or secondarily posttreatment. The concept of neurapraxic nerve injury makes most surgeons choose to ‘watch and see’ the nerve recovery before deciding second surgery if the nerve does not recover. We report three cases of nerve injury in SCHF, all of which underwent nerve exploration for different reasons. Early reduction in the Casualty is important to release the nerve tension before transferring the patient to the operation room. If close reduction fails, we proceed to explore the nerve together with open reduction of the fracture. In iatrogenic nerve injury, we recommend nerve exploration to determine the surgical procedure that is causing the injury. Primary nerve exploration will allow early assessment of the injured nerve and minimize subsequent surgery.

Neurostenalgia is a neuropathic pain that results from continuing irritation of an anatomically intact nerve by a noxious agent. The pain resolves promptly after surgical release of the nerve. The authors report a case of neurostenalgia of the radial nerve in which the posterior interosseous branch was compressed at the arcade of Frohse, presenting with severe arm and elbow pain. The pain was immediately relieved after surgical release of the nerve.

Sometimes serious tension occurs in the radial nerve when doing internal fixation for distal humerus shaft fracture or neurorrhaphy for radial nerve injury. Medial transposition of radial nerve on fracture site can avoid direct radial nerve injury by fracture fragment, radial nerve tension by plating for distal humerus shaft fracture, and also safe from neural tension during neurorrhaphy of damaged radial nerve. We reported here total 6 cases of backward transposition of radial nerve including 2 cases of radial nerve injury associated with humerus fracture and 4 cases of comminuted fracture of humerus shaft.

OBJECTIVE: To investigate the possibility of volume conduction in the superficial radial sensory nerve conduction study in patients with a complete radial nerve injury. METHOD: In patients with a complete radial neuropathy, a superficial radial sensory nerve conduction study was carried out by an antidromic and orthodromic methods. Antidromic technique was carried out by increasing stimulus intensity gradually. Median palmar cutaneous nerve conduction study was also carried out by an antidromic method. RESULTS: When the stimulus intensity was significantly higher than the optimal technique, a median palmar cutaneous nerve action potential was evoked instead of the superficial radial nerve action potential. This is a volume conducting potential which occurrs following a high intensity stimulus. CONCLUSION: Superficial radial sensory conduction study must be carried out by an optimal stimulus intensity and an orthodromic method to eliminate the effect of volume conduction.

The authors reported the one case of posterior interosseous nerve syndrome, which had been operated and shown the good result. The posterior interosseous nerve syndrome is a neuropathy of deep musclar branch of the radial nerve. This nerve can be compressed by tumors, ganglia, elbow synovitis, or by a spontaneous compression that may occur at the point of passage through the 'arcade of Frohse'. This case had shown the vascular leash constricting the posterior interosseous nerve justproximal to the arcadet of Frohse, and the nerve below the constriction was atrophied. We reviewed other cases from the iterature in view of clinical features and management.

Most textbooks describe the brachialis muscle is innervated by the musculocutaneous and radial nerves. This study was performed to clarify the incidence and morphology of the branch of the radial nerve to the brachialis muscle. Eighty sides of 40 adult Korean cadavers were used in this study. The incidence of the radial nerve to the brachialis muscle was 75% of 80 sides and the radial nerve was innervated bilaterally in 65% (26 sides). The number of the branch arising from the radial nerve was one (65%), two (31.7%) or three (3.3%). The average distance from the lateral epicondyle to the branch arising from the radial nerve was 68.5 mm (range: 4 ~126 mm). The brachialis muscle received a branch from radial nerve, through a descending branch (58.5%), a transverse branch (26.8%) or an ascending branch (14.6%). A branch of the radial nerve was usually divided into one or two branches (79.3%) before piecing the brachialis muscle. The average distance from the lateral epicondyle to the perforating point of the branch was 52.4 mm (range: 3 ~123 mm). The branch of the radial nerve penetrated inferior and middle third of the brachialis muscle in 44.2% and 53.2% respectively.

The cases of 82 humeral shaft fractures were evaluated at the Department of Orthopedic Surgery, Chosun University Hospital, during the ten years period from January 1978 to December 1987 and the following results were obtained. 1. The most common type was transverse fracture (59.8%) and the most common site was middle one third (61.0%). 2. The average time of bone union were about 9.6 weeks in non-operative cases and 9 weeks in operative cases. 3. The radial nerve palsy was more common in transverse fracture of humerus at the middle one third level. 4. Among the 28 radial nerve palsy associated with humerus fracture, 19 cases were treated by conservatively, and 9 cases were treated by surigical exploration. 73.7% of conservatively treated cases and 77.0% of operatively treated cases regained most of the functional lost of the radial nerve.
