[Jamming a child's finger: an experimental study to determine elastic resistance and the point of onset of bone/joint deformation].
Knowledge of the elastic properties of children's fingers is very important to understand the potential hazard for jamming injuries that exists in modern motor vehicles with automatic power-operated windows. This study determined the elastic resistance and the point of onset of bone/joint deformation at each of 5 different jam positions of a child's finger under continuous dorsal-palmar compression. An unembalmed finger that recently had been surgically removed from a polydactylic 8 month-old girl was jammed in a custom hydraulic test apparatus. ⋯ The mean force at the point of onset of bone/joint deformation was 78.4 N. The current statutory limit of 100 N for the maximum closing force of an automatic power-operated motor vehicle window is thus well beyond the point at which finger injuries can occur in children. Assuming finger injuries in children can occur at a jamming force below approximately 80 N, a reduction of the statutory limit to us higher than 50 N is reasonable.

Review[Transfer of the posterior tibialis tendon to restore an active dorsiflexion of the foot].
After lesions of the peroneal nerve or damage of the tibialis anterior muscle a lack of active dorsiflexion leads to a drop foot deformity. Ober (1933) described a transfer of the posterior tibialis tendon to the dorsum of the foot to restore active extension of the foot. The aim of this retrospective study was to evaluate the results of this method and to compare our results with those in the literature. ⋯ The Stanmore score revealed an average of 62 points with an excellent result in 2, a good result in 5, a fair result in 2 and a poor result in 5 patients. Transfer of the posterior tibial muscle to restore active dorsiflexion of the foot is a therapeutic option. As it is known from the literature objective results were mostly fair, but there was a high degree of satisfaction among the patients.

[Clinical and radiological results after operative treatment of mallet fracture using Kirschner wire technique].
In our clinic dorsal distal phalanx fractures involving more than 30% of the articulare line in the lateral view are treated operatively using the Kirschner wire technique. Recently conservative treatment of these fractures is more and more recommended. Therefore we investigated in a retrospective study our patients with special regards to complications. ⋯ Because of unsatisfactory results in 63% (n=20), conservative treatment will be our treatment of choice in the future. Operative treatment will only be done in patients with subluxation of the distal phalanx.

[Results after osteosynthesis of extraarticular proximal phalangeal fractures].
The aim of the study was to retrospectively present and analyse the functional results of surgically treated extraarticular fractures of the proximal phalanx. From 1/2005-4/2008 we operated on 49 patients with 52 closed, extraarticular fractures of the proximal phalanx of the long fingers with either pins, screws or plates. 30 patients were male, 19 were female, the mean age was 35 years. Open fractures, fractures of the thumb and those with injuries to neurovascular structures or tendons were excluded. ⋯ The remaining 11 patients showed a good outcome with a TAM between 220° and 239°. These favourable results remained subjectively stable at the end of the observation period, when all patients could be contacted by phone. Osteosynthesis by kirschner wires, screws and plates for closed extraarticular fractures of the proximal phalanx of the long fingers gives good to excellent results with few complications.

Case Reports[Osteotendocutaneous radial forearm flap for hand reconstruction following circular saw injury].
Circular saw injuries may cause severe damage to the soft tissue of the hand, including destruction of skin, tendons and bone. We report the use of an osteotendocutaneous radial forearm flap for hand reconstruction following circular saw injury. This flap allowed simultaneous reconstruction of skin, tendon and osseous defect of the metacarpal bone.
