1/36. Entrapment of the median nerve in a greenstick forearm fracture. A case report and review of the literature.We report a case of low median nerve palsy occurring as a complication of a closed both-bone forearm fracture in a child. Following delayed diagnosis, surgical exploration was performed and it was observed that the median nerve was entrapped in the callus of the radius fracture.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/36. median nerve compression associated with displaced Salter-Harris type II distal radial epiphyseal fracture.Three children with grossly displaced Salter-Harris Type II fractures of the distal radial epiphysis underwent immediate manipulation under anaesthetic (MUA) because of rapidly developing median nerve compression. In each case nerve function was quickly restored with no late neurological sequelae. We believe that in children who sustain this injury with signs of median nerve compression, immediate MUA without carpal tunnel release is acceptable initial management. Late exploration of the median nerve can be considered should a neurological deficit persist.- - - - - - - - - - ranking = 1.3335894027207keywords = nerve, injury (Clic here for more details about this article) |
3/36. Bilateral median nerve compression at the level of Struthers' ligament. Case report.Struthers' ligament syndrome is a rare cause of median nerve entrapment. Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve's dermatomal area. The authors present the case of a 21-year-old woman with bilateral median nerve compression caused by Struthers' ligament. She underwent surgical decompression of the nerve on both sides. To the authors' knowledge, this case is the first reported bilateral compression of the median nerve caused by Struthers' ligament. The presentation and symptomatology of Struthers' ligament syndrome must be differentiated from median nerve compression arising from other causes.- - - - - - - - - - ranking = 1.8333333333333keywords = nerve (Clic here for more details about this article) |
4/36. Intraneural perineurioma involving the median nerve.Intraneural perineurioma is a rare clinical entity, which tends to affect major nerve trunks in the upper extremities. On light microscopy, numerous pseudo-onion-bulb structures having a central clear area are surrounded by concentric layers of eosinophilic elongate cells having spindled nuclei. immunohistochemistry of concentric cells stains positive for epithelial membrane antigen but negative for S100 protein. Because of the small number of cases, no consensus has been made on proper treatment of this entity. Although none of the patients who have had excision of tumor with nerve grafting have had sensory nerve recovery, we believe each patient should be individualized until more data are available regarding this tumor.- - - - - - - - - - ranking = 1.1666666666667keywords = nerve (Clic here for more details about this article) |
5/36. Contribution of magnetic resonance imaging for the diagnosis of median nerve lesion after endoscopic carpal tunnel release.Deterioration of pre-existing signs or appearance of a nerve deficit raise difficult problems during the complicated course following endoscopic carpal tunnel release. One possible explanation is transient aggravation of nerve compression by passage of the endoscopy material, but these signs may also be due to incomplete section of the flexor retinaculum or an iatrogenic nerve lesion. Each case raises the problem of surgical revision. The authors report three cases of open revision in which MRI allowed a very precise preoperative diagnosis of the lesions and all of the MR findings were confirmed during surgical revision. In the first case, MRI showed section of the most radial branches of the median nerve (collateral nerves of the thumb, index finger and radial collateral nerve of the middle finger). The proximal origin of the nerve of the 3rd web space, above the retinaculum, an anatomical variant, was also identified. Section of 2/3 of the nerve of the 3rd web space, proximal to the superficial palmar arch, was observed in the second case. Simple thickening of the nerve of the 3rd web space, without disruption after opening of the perineurium, was observed in the third case. MRI therefore appears to be an examination allowing early and precise definition of indications for surgical revision in this new iatrogenic disease.- - - - - - - - - - ranking = 2.1666666666667keywords = nerve (Clic here for more details about this article) |
6/36. Synovial osteochondromatosis at the elbow producing ulnar and median nerve palsy. Case report and review of the literature.The authors present the case of a 53-year-old woman suffering from synovial osteochondromatosis of her right elbow responsible for ulnar and median nerve entrapment neuropathy. This condition is characterised by the formation of multiple cartilaginous nodules in the metaplastic synovium of otherwise normal joints, bursae or tendon sheaths. Treatment consisted of partial synovectomy, removal of loose bodies and microscopic nerve release. Synovial osteochondromatosis complicated by nerve compression syndromes has been rarely reported, usually with ulnar tunnel syndrome at the elbow. The literature on this subject is reviewed.- - - - - - - - - - ranking = 1.2597842872401keywords = nerve, neuropathy (Clic here for more details about this article) |
7/36. Hyperostotic macrodactyly and lipofibromatous hamartoma of the median nerve associated with carpal tunnel syndrome.A new case with 14-year follow-up of an extremely rare variety of congenital hand macrodactyly is presented. The disease characteristically presents a diffuse proliferation of fibrofatty tissue, but in this special type, osteocartilaginous deposits around the joints can also be found. The case presented included the troublesome feature of a lipofibromatous hamartoma in the median nerve at the wrist and its branches producing carpal tunnel syndrome. The patient obtained benefit from carpal tunnel release and epineurolysis. The hyperostotic development was managed with conservative resection of the periarticular osteochondromas. The literature reviewed suggests that the hyperostotic cases of macrodactyly do not differ from general cases of this congenital condition, except for the osteochondral deposits. These tumours develop during adulthood or after previous trauma, before epiphyseal closure.- - - - - - - - - - ranking = 0.83339419378587keywords = nerve, trauma (Clic here for more details about this article) |
8/36. median nerve compression by a radially inserted palmaris longus tendon after release of the antebrachial fascia: A complication of carpal tunnel release.We describe a case that had recurrent median nerve compression after release of the antebrachial fascia in carpal tunnel release. The nerve was compressed by a palmaris longus tendon that was inserted radially into the thenar fascia. After decompression (detachment of the tendon) the patient had symptom relief. Release of the antebrachial fascia in the presence of this tendon variant carries a risk of median nerve compression by the tendon.- - - - - - - - - - ranking = 1.1666666666667keywords = nerve (Clic here for more details about this article) |
9/36. An unusual schwannoma of the median nerve: effects on the motor branch.An unusual case of a schwannoma of the median nerve is presented where pressure due to the tumour on the motor branch to the thenar muscles caused weakness and wasting of the abductor pollicis brevis muscle, a previously unreported phenomenon. The patient achieved a full functional recovery after enucleation, which is also unusual considering the patient's age. Aspects of schwannoma biology, differential diagnosis, investigation and treatment are discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = nerve (Clic here for more details about this article) |
10/36. Severe, traumatic soft-tissue loss in the antecubital fossa and proximal forearm associated with radial and/or median nerve palsy: nerve recovery after coverage with a pedicled latissimus dorsi muscle flap.A total of 6 patients with complex, traumatic wounds of the antecubital fossa and proximal forearm were included in this study. All patients presented with radial and/or median nerve palsies in addition to their soft-tissue defect. Except for 1 patient with a 15-cm defect of the radial nerve, all other traumatized nerves appeared in-continuity at the time of surgery. However, the nerve injury was severe enough to induce wallerian degeneration (i.e., axonotmesis in traumatized nerves in-continuity). Three patients required brachial artery reconstruction with a reverse saphenous vein graft. Wound coverage was accomplished using a pedicled latissimus dorsi muscle flap, which was covered with a split-thickness skin graft. Successful reconstruction was obtained in all patients. Follow-up ranged from 2 to 6 years. The range of motion at the elbow and forearm was considered excellent in 5 patients and good in the remaining patient who had an intra-articular fracture. Motor recovery of traumatized nerves in-continuity was observed in all but 1 patient who had persistent partial anterior interosseous nerve palsy. The grip strength of the injured hand measured 70% to 85% of the contralateral uninjured hand. median nerve sensory recovery was excellent in all patients. The versatility of the pedicled latissimus dorsi muscle flap for coverage of these complex wounds with traumatized neurovascular bundles around the elbow is discussed.- - - - - - - - - - ranking = 2.708277673485keywords = nerve, nerve injury, injury, trauma (Clic here for more details about this article) |
