[Prostheses for fingernails].

For most hand surgeons, flexor tendon repairs in zone 2 of the hand still present a clinical problem. The surgeon is placed in a dilemma: on the one hand, if repair is achieved and the finger is kept immobile during the healing phase, dense adhesions may bind the tendons within the sheath and limit motion. On the other hand, uncontrolled early flexion may disrupt the tendon repair. Early 'controlled motion' increases tensile strength, reduces the formation of adhesions and improves clinical results. To investigate the relationship between the patient's compliance concerning the post-operative motion regimen and the final range of motion, a device has been developed which records when and how often the patient exercises. The device is attached to a modified Kleinert splint. This configuration enables comparison of the outcome of the rehabilitation of patients who exercise according to the rehabilitation programme with patients who exercise less often. The device measures for up to one week. It is possible to download the available measurement samples (exercise count per quarter of an hour) for inspecting the training course or for further analysis/statistics.

[Does osseous extensor tendon avulsion or rupture really exist? Histologic plastination studies of insertion of the extensor aponeurosis and significance for operative therapy].

With the help of thick, transparent finger cross sections, it was shown that fibers of the extensor aponeurosis insert distal to the avulsed fragment of the distal phalanx. The consequence for hand surgery is not to expose the fragment through a dorsal incision, but through a mid-lateral one. In this way, the distant parts of the aponeurosis distal to the fracture remain intact, and there is no break in the continuation of the dorsal extension plate.
