[Carpal tunnel syndrome in haemodialysis patients: analysis of clinical and electrophysiological findings in 268 patients (395 hands)].
Along with arthropathies, carpal tunnel syndrome (CTS) may occur in patients on chronic haemodialysis, its incidence is correlating with the duration of the haemodialysis treatment. To evaluate clinical and electrophysiological findings, relation of the disease to the side of the arteriovenous shunt, gender ratio, and a concurrent tendovaginosis stenosans (TVS), 268 haemodialysis-patients with CTS or recurrent CTS were retrospectively analyzed. METHODS AND (CLINICAL) MATERIAL: Over a period of ten years (1994 - 2003), 268 haemodialysis patients presented to our peripheral neurosurgery practice with CTS or recurrent CTS. Diagnosis was confirmed with clinical and electrophysiological findings. The patients were divided into three groups based on their severity of disease as follows: Patients with only intermittent paraesthesias (CTS I degrees ), with persistent numbness in the area supplied by the median nerve (CTS II degrees ), and with paresis of the thenar muscles (CTS III degrees ). The average distal motor latency (DML), loss of sensory nerve action potentials (SNAP), and/or motor action potentials (MAP) were used as electrophysiological parameters. ⋯ CTS is a typical complication of chronic haemodialysis, and differs from idiopathic CTS by a gender ratio of 1 : 1, a high frequency of concurrent TVS, as well as a tendency to recur. Since compression of the median nerve was found preferentially on the shunt-side, haemodynamic factors may play a role in the pathogenesis of the disease in addition to amyloidosis. Haemodialysis patients complaining of paraesthesia in their hands should undergo electrophysiological examination, even if a successful CTS-operation was performed in the past.

[Recurrences of carpal tunnel syndrome in long-term haemodialysis patients].
Multiple recurrences of carpal tunnel syndrome and increased malfunction of the hand caused by tendopathies and arthropathies occur in long-term (20 - 30 years) haemodialysis and are mainly influenced by beta2-microglobulin amyloidosis. ⋯ In long-term (more than 20 - 30 years) haemodialysis patients suffering from arthropathies, tendopathies and recurrent carpal tunnel syndrome, removal of the flexor digitorum superficial tendons should be considered for the second recurrence to improve pain and finger mobility.
