[Complex regional pain syndrome versus chronic regional pain syndrome (Hand-Finger Syndrome)].

Dystrophy is a main factor of CRPS. A large number of patients do not develop dystrophy but, instead, they suffer from pain with limitation in movement, possible paraesthesia and/or swelling. This is then a chronic regional pain syndrome or (shoulder-arm-) hand-finger syndrome.

[The Mantero technique for flexor tendon repair - an alternative?].

Purpose: Regaining free tendon gliding after reconstruction of flexor tendons is essential to restore full function to the affected finger. Mantero et al. described a pull-out suture technique for the repair of flexor digitorum profundus (FDP) lesions in zone 1, allowing early postoperative active mobilisation and thus minimizing the risk of tendon adhesions.

[Repeat interventions after decompression of the carpal tunnel].

If after carpal tunnel release, symptoms continue or progress, or if new ones appear, they must be examined thoroughly and differentiated. Such symptoms may hint at incomplete splitting of the retinaculum flexorum, a more proximally located nerve compression (faulty diagnosis or double-crush syndrome), a general or a new disease, a previously unrecognized or a new hypertrophic synovialitis, a hypertrophically contracted scar, or a neuroma. Iatrogenic lesions have frequently been reported.

The synovial flap as treatment of the recurrent carpal tunnel syndrome.

After an exact definition of the recurrent carpal tunnel syndrome, its treatment, as described in the literature, is presented. To cover the median nerve isolated from the extended scar tissue with a thin and well-circulated tissue, the author proposes and demonstrates the synovial flap. The follow-up of 27 cases operated since 1979 with a follow-up time between 1 month to 14 years shows 6 excellent, 16 good, 3 satisfactory and 2 bad results.
