1/55. carpal tunnel syndrome caused by the palmaris profundus muscle. Case report.The palmaris profundus muscle is a rare structure that originates from the radial portions of the forearm. Its discrete tendon passes through the carpal tunnel, attaching distally to the palmar aponeurosis. If it interferes with the median nerve it may cause carpal tunnel syndrome. The finding can be compared with similar observations in comparative anatomy.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
2/55. Ulnar conduction block at the wrist.Two cases of ulnar nerve lesions at the wrist are reported. The lesions had an acute onset and exclusively impaired the ulnar motor deep branch. The coexistence of carpal tunnel syndrome in each case allowed an early diagnosis but was somewhat misleading. In both cases, the use of classic motor and sensory conduction studies did not provide clear abnormalities that would have precisely determined the site of the nerve lesion. In both cases, only palmar stimulation of the ulnar motor deep branch showed an important conduction block. This electrodiagnostic finding showed definitively the site of the ulnar nerve lesion at the wrist and excluded proximal ulnar nerve lesions or C8-T1 radiculopathy. In both cases recovery occurred without surgery.- - - - - - - - - - ranking = 0.16666666666667keywords = palm (Clic here for more details about this article) |
3/55. Split median nerve.carpal tunnel syndrome is encountered frequently in the every day practice for many orthopaedic surgeons and neurosurgeons. However, the rate of recurrence or incomplete relief is high and difficult to treat. This may be related to the high percent of anomalies of the median nerve and its surrounding tissues. A case of a split median nerve entrapped by an abnormally inserted palmaris longus muscle is presented. The case is discussed and a conclusion of safer standard surgical release is recommended, especially in doubtful cases.- - - - - - - - - - ranking = 0.16666666666667keywords = palm (Clic here for more details about this article) |
4/55. 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 = 0.16666666666667keywords = palm (Clic here for more details about this article) |
5/55. ulnar nerve compression by an anomalous muscle following carpal tunnel release: a case report.We describe the acute development of ulnar nerve compression following carpal tunnel release in a patient with an accessory palmaris longus muscle. Although anomalous muscles in the wrist are relatively common and may produce ulnar nerve compression, this particular occurrence following carpal tunnel release has not been previously described in the literature. We theorize that the compression of the ulnar nerve proximal to Guyon's canal was caused by increased tension along the long axis of the anomalous accessory palmaris longus muscle as a consequence of transverse carpal ligament division.- - - - - - - - - - ranking = 0.33333333333333keywords = palm (Clic here for more details about this article) |
6/55. 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 = 0.83333333333333keywords = palm (Clic here for more details about this article) |
7/55. Fibrolipoma of the median nerve: a case report and review of the literature.A 38 year-old patient presented with right median nerve distribution paresthesias. Electrodiagnostic studies confirmed severe carpal tunnel syndrome. A palmar mass prompted a magnetic resonance imaging scan, which suggested a fibrolipoma of the median nerve. Carpal tunnel release resulted in resolution of preoperative pain and paresthesias. We review the literature dealing with this primary nerve tumor.- - - - - - - - - - ranking = 0.16666666666667keywords = palm (Clic here for more details about this article) |
8/55. Aggressive keloid scarring of the Caucasian wrist and palm.keloid scarring of the distal upper extremity is very rare. We report a Caucasian woman who presented with aggressive keloids of the hand and wrist causing De Quervain's syndrome, superficial radial-nerve entrapment and ulnar-nerve compression at the wrist. Multiple operations were required to alleviate her symptoms. A number of management conundrums arose, requiring defensive planning to pre-empt the possible complications of recurrent keloid scarring as a result of the surgical procedures.- - - - - - - - - - ranking = 0.66666666666667keywords = palm (Clic here for more details about this article) |
9/55. myoclonus of peripheral origin: case secondary to a digital nerve lesion.We present a patient with myoclonus of the left hand appearing 1 month after surgical correction of a stenosing tenosynovitis of the thumb. An extensive fibrosis of the external palmar digital nerve was shown, and the successful liberation of this median nerve terminal branch completely and rapidly eliminated the movement disorder.- - - - - - - - - - ranking = 0.16666666666667keywords = palm (Clic here for more details about this article) |
10/55. Entrapment neuropathy of the palmar cutaneous branch of the median nerve concomitant with carpal tunnel syndrome: a case report.A case of the entrapment neuropathy of the palmar cutaneous branch of the median nerve, concomitant with carpal tunnel syndrome is presented. This report demonstrates that the Semmes-Weinstein monofilament test and nerve conduction studies can identify entrapment of the palmar cutaneous branch of the median nerve concomitant with carpal tunnel syndrome.- - - - - - - - - - ranking = 1keywords = palm (Clic here for more details about this article) |
