Several recent reports have described the minimally invasive plate osteosynthesis (MIPO) technique in the treatment of humeral shaft fractures by the anterior approach. The purpose of this study is to identify the danger zone for locking screw placement to avoid musculocutaneous nerve injury in the anterior compartment and radial nerve injury in the posterior compartment of the humerus relative...

OBJECTIVE To demonstrate the new sensory restoration technique in radial nerve injury using the first branch of dorsal ulnar cutaneous nerve as the donor sensory nerve. MATERIAL AND METHOD Forty formalin-preserved cadavers (18 males and 22 females) were used as the subjects of the present study. The localization of the origin of first branch of dorsal ulnar cutaneous nerve was performed. The ...

introduction: nerve repair is performed in different ways, but which way leads to better results is not known for ceratin. one way is epiperineurial procedure. in this method the fasicules of the nerve are sawn together by thin thread separately. this study aimed to investigate the results of epiperineurial method. materials and methods: in this study 21 subjects who were admitted in taleghani ...

Electromyography and conduction studies in motor and sensory fibres were performed in 58 patients with different types of radial nerve injury. The site of nerve injury was predicted by clinical and electromyographic findings and correlated with changes in conduction, thereby permitting a more exact classification of the type of nerve injury. In patients with Saturday-night palsy, there was cons...

The radial nerve is at risk of injury during surgical approaches to the humeral shaft. Previous authors have described an anterolateral approach to the humerus limited by the radial nerve, requiring that distal dissection be carried anterior into a neurovascularly crowded interval. A novel extensile approach is described using a neuromuscular bridge to protect the radial nerve, thus enabling sa...

Minimally Invasive Plate Osteosynthesis (MIPO) has gained popularity with satisfactory clinical outcomes in the treatment of long bone fractures. MIPO for humeral shaft fractures, however, could be a surgically dangerous procedure because of the risk of radial nerve injury. An anatomical study was performed to evaluate the feasibility of MIPO for the humeral shaft fractures, and to study the re...

Fractures of the radial head and radial neck correspond to 1.7-5.4% of all fractures and approximately 30% may present associated injuries. In the literature, there are few reports of radial head fracture with posterior interosseous nerve injury. This study aimed to report a case of radial head fracture associated with posterior interosseous nerve injury. CASE REPORT A male patient, aged 42 y...

Although usually omitted in the description of nerve injuries in the newborn, radial nerve palsies are not infrequent. The cause of the paralysis is not clear but the occasional coincidental finding of a patch of subcutaneous fat necrosis over the course of the radial nerve (Lightwood, 1951) suggests the possibility of direct trauma to the nerve. That the injury is not uncommon is supported by ...

Iatrogenic injury during the posterior approach to the humerus during operative fixation is not an uncommon occurrence. A comprehensive understanding of the normal anatomy and its variants is of paramount importance in order to avoid such injury. Typically, the inferior lateral cutaneous branch of the radial nerve originates towards the distal end of the humerus at the inferior portion of the s...

Radial nerve injuries in displaced extension-type supracondylar humeral fractures in children are well known. Entrapment in fracture of radial nerve is uncommon and rarely evocated in literature. We report two similar cases in the mechanism of injury, the clinical findings and the treatment and propose therapeutic guidelines.
