1. Three cases of fatty infiltration of the median nerve are reported. 2. One patient had symptoms of median nerve compression. 3. The intimate association of fibro-fatty tissue within the nerve precludes enucleation of the swelling

1. Two cases are reported in which there was diffuse fibro-fatty overgrowth or tumour formation involving the adipose tissue of the median nerve. In each the diagnosis was confirmed by operation and histological examination. 2. The first case is an example of the developmental abnormality usually referred to as "macrodystrophia lipomatosa." The second case should be termed fibrolipoma. 3. The literature is reviewed; no case of fibrolipoma has been recorded

A variation of the motor branch of the median nerve is described in which this branch arose more proximally and pierced the flexor retinaculum. Its significance during a carpal tunnel decompression is pointed out

1. A lesion of the median nerve after reduction of a dislocated elbow in a boy of nine is recorded. 2. The nerve lesion was progressive, and at operation on the seventh day after injury the nerve was found to be trapped in the joint between the humerus and the ulna. 3. The nerve was freed and gradual recovery occurred

1 . The clinical results in forty cases of repair of the median nerve at the wrist have been examined. Almost half were unsatisfactory. 2. The factors that may have predisposed to failure of adequate re-innervation are discussed. 3. The results might be improved by the use of radio-opaque markers for early detection of separation at the suture line, and by the use of frozen sections to determine the adequacy of resection

Two cases of delayed median nerve division after laceration of the wrist by glass are described. In both there was no neurological damage at the time of the original injury. However, retained fragments of glass were subsequently responsible for division of the median nerve in both cases and of the surrounding tendons in one. Radiographs were an important diagnostic aid in treating the delayed injury

Two boys with entrapment of the median nerve in the elbow joint after closed reduction of a posterior dislocation with fracture of the medial epicondyle showed a characteristic radiological sign in the anteroposterior radiograph after two to three months. The sign was a depression in the cortex on the ulnar side of the distal humeral metaphysis, with interruption of the local periosteal reaction. At operation in both patients the depression was found to correspond with the place where the median nerve reached the posterior surface of the humerus. Radiographs taken after transverse section of the nerve above and below the joint capsule and end-to-end suture showed gradual disappearance of the cortical depression

1. A case, believed to be the fifth on record, of supracondylar fracture with rupture of the brachial artery is described. 2. The relative immunity of the median nerve in these injuries is discussed, with brief reference to a recent case of complete rupture. Only a single previous report of this complication could be found. 3. It is suggested that these injuries are less uncommon than the number reported would indicate. 4. The anatomy of severe displacement is discussed, with special reference to the role of the brachialis. 5. The danger of closed reduction when the relationship of the upper fragment to the neurovascular bundle is in doubt is stressed. 6. The indications for open reduction are given

Aims. The sensitivity and specificity of electrodiagnostic parameters in diagnosing carpal tunnel syndrome (CTS) have been reported differently, and this study aims to address this gap. Methods. This case-control study was conducted on 57 cases with CTS and 58 controls without complaints, such as pain or paresthesia on the median nerve. The main assessed electrodiagnostic parameters were terminal latency index (TLI), residual latency (RL), median ulnar F-wave latency difference (FdifMU), and median sensory latency-ulnar motor latency difference (MSUMLD). Results. The mean age in cases and controls were 50.7 years (SD 9.9) and 47.9 years (SD 12.1), respectively. The CTS severity was mild in 20 patients (34.4%), moderate in 19 patients (32.8%), and severe in 19 patients (32.8%). The sensitivity and specificity of the electrodiagnostic parameters in diagnosing CTS were as follows: TLI 75.4% and 87.8%; RL 85.9% and 82.5%; FdifMU 87.9% and 82.9%; and MSUMLD 94.8% and 60.0%, respectively. Conclusion. Our findings indicated that electrodiagnostic parameters are significantly associated with the clinical manifestation of CTS, and are associated with high diagnostic accuracy in CTS diagnosis. However, further studies are required to highlight the role of electrodiagnostic parameters and their combination in CTS detection. Cite this article: Bone Jt Open 2024;5(10):898–903

Abstract. Nerve transfer has become a common and often effective reconstructive strategy for proximal and complex peripheral nerve injuries of the upper limb. This case-based discussion explores the principles and potential benefits of nerve transfer surgery and offers in-depth discussion of several established and valuable techniques including: motor transfer for elbow flexion after musculocutaneous nerve injury, deltoid reanimation for axillary nerve palsy, intrinsic re-innervation following proximal ulnar nerve repair, and critical sensory recovery despite non-reconstructable median nerve lesions
