1/33. 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.

2/33. The double-crush phenomenon--an unusual presentation and literature review.

    The double-crush syndrome was initially described by Upton and McComas in 1973. They postulated that nonsymptomatic impairment of axoplasmic flow at more than one site along a nerve might summate to cause a symptomatic neuropathy. This was suggested by their clinical observation that the majority of their patients had a median or ulnar neuropathy associated with evidence of cervicothoracic root lesions. They also hypothesized that one of the constraints on axoplasmic flow could be a metabolic neuropathy, and this is supported by the high association of diabetes and carpal tunnel syndrome. Other researchers have since reported series of patients supporting the frequent association of a proximal and distal nerve compression syndrome, including carpal tunnel syndrome associated with cervical radiculopathy, brachial plexus compression, and diabetic neuropathy. Subsequently, MacKinnon and Dellon have expanded the description of this syndrome to include a) multiple anatomic regions along a peripheral nerve, b) multiple anatomic structures across a peripheral nerve within an anatomic region, c) superimposed on a neuropathy, and d) combinations of the above. We present an unusual case of symptomatic nerve compression caused by two nonanatomic structures within an anatomic region.

3/33. Tardy ulnar tunnel syndrome caused by Galeazzi fracture-dislocation: a neuropathy with a new pathomechanism.

    We present a case of late-onset ulnar tunnel syndrome following a Colles fracture. The nerve palsy was caused by a vascular branch that stretched over the ulnar head, compressing the nerve and generating friction against the ulnar head when the forearm was rotated. This is the first report of such a pathomechanism.

4/33. ulnar nerve compression at the wrist by a synovial cyst successfully treated with percutaneous puncture and corticosteroid injection.

    A case of ulnar nerve palsy due to a conduction block in the deep motor branch at the wrist is reported. The cause was a rapidly growing synovial cyst. ultrasonography and computed tomography were performed to determine the exact location of the cyst, which was punctured and injected with corticosteroid. Function promptly returned to normal after this procedure.

5/33. 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.

6/33. Ulnar neuropathy caused by a lipoma in Guyon's canal--case report.

    A 74-year-old female presented with a 3-month history of compression neuropathy of the right ulnar nerve in Guyon's canal. magnetic resonance imaging and ultrasonography revealed the location of the mass lesion. Surgical exploration discovered a lipoma pressing against both the ulnar nerve and the ulnar artery. The mass was extirpated. The postoperative course was uneventful with good function recovery.

7/33. Atypical compression of the deep branch of the ulnar nerve in Guyon's canal by a ganglion. Case report.

    A 61-year-old woman with an ulnar claw-finger deformity but no sensory loss had a cystic lesion excised from Guyon's canal. The ganglion was in zone 1 of the canal, which is associated with both motor and sensory deficit, but on this occasion it caused motor dysfunction alone.

8/33. ulnar nerve injuries of the hand producing intrinsic muscle denervation on magnetic resonance imaging.

    Muscle and nerve injuries in the hand may be difficult to detect and diagnose clinically. Two cases are reported in which magnetic resonance imaging showed ulnar nerve injury and intrinsic hand muscle denervation. The clinical, anatomical and radiological features of injury to the deep motor branch of the ulnar nerve and associated muscle denervation are discussed and illustrated.

9/33. electrodiagnosis in entrapment neuropathy by the arcade of Struthers.

    Two cases of high ulnar nerve neuropathy are reported. Lesions were localized at the midarm level by electrophysiologic studies. In the first case, the lesion was found mainly to be a prolonged neurapraxia, and neurolysis was effective. The ulnar nerve was swollen 1 cm in length under the arcade of Struthers. After neurolysis, the palsy recovered rapidly. In the other case, the lesion seemed to be a mild injury to the myelin sheath. Delayed segmental conduction velocity and partial conduction block were found at the midarm level. The paresis improved slightly during the 11-month followup without any treatment, but the electrophysiologic studies were unchanged. In both cases, physical examination did not distinguish the lesions from cubital tunnel syndrome. Electrophysiologic examination proved to be effective as a diagnostic procedure. In the presence of ulnar neuropathy, the upper arm segment should be included in a routine nerve conduction study to screen for the rare but important entrapment neuropathy caused by the arcade of Struthers.

10/33. thumb digital neuropathy caused by splinting.

    Healthcare professionals are currently faced with a great variety of splints and splinting materials. Choices range from prefabricated products to custom splints made on-site from plaster, orthoplast, or fiberglass. In addition to providing immobilization to maintain a particular posture, a splint must protect important soft tissues. patients with hand or wrist injuries often receive a prefabricated metal cock-up wrist splint in emergency departments. Complications from splints are not uncommon but are infrequently reported. We report a case in which a metal wrist cock-up splint caused compression of the thumb ulnar digital nerve. Preventive measures for such complication are included.
