[Diagnosis and therapy of carpal tunnel syndrome--guideline of the German Societies of Handsurgery, Neurosurgery, Neurology, Orthopaedics, Clinical Neurophysiology and Functional Imaging, Plastic, Reconstructive and Aesthetic Surgery, and Surgery for Traumatology].

Evidence-based supradisciplinary guideline that deals with the epidemiology, pathogenesis, symptoms, clinical and electrophysiological diagnosis, supplementary imaging investigations, differential diagnosis, conservative and surgical treatments, prognosis and course along with complications and revision surgery. The recommendations on investigation and treatment are based on a comprehensive literature search with critical evaluation and two consensus methods (expert group and Delphi technique) within the participating specialist societies. Besides this long version, a short version and a patient version can be viewed through the AWMF platform.

[Lipoma as a rare cause of nerve compression syndrome in the hand and forearm].

We report on three patients who were operated on peripheral nerve compression syndromes in the hand and forearm caused by a lipoma. After surgical removal of the lipoma, distinct improvement or even recovery of symptoms was observed.

[Acute perilunar dislocations: algorithm for treatment].

In most cases, perilunar dislocations of the wrist are caused by high speed accidents. Usually these injuries occur by a fall on the dorsiflexed superextension of the hand. The instability caused by injuries of various erticular structures (ligament, bone) show various developmental stages.

Results of flexor tendon repair of the hand by the motion-stable wire suture by Towfigh.

We compared the motion-stable wire suture by Towfigh (MSWST) with a modified Kessler suture (MKS) by following up flexor tendon repairs (MSWST, n = 21/39 digits; MKS, n = 20/31 digits). For MSWST we found 31 (79.5%) "excellent", 3 (7.
