Background: Severely comminuted distal radius fractures can be treated by different methods. Our routine procedure in dorsal dislocated fractures is the dorsal stabilization with two 1/4 tube plates. The new pi-plate is an other device that matches optimally the anatomy of the distal radius and allows a near half-circumferential dorsal buttress of comminuted intraarticular and extra-articular radial fractures.

Two different types of cell-line and fresh human osteoblasts, cultured from cancellous bone grafts from the iliac crest, were used for the study. Three different biomaterials were compared regarding biocompatibility: titanium, steel and hydroxyapatite. The cells were fibroblast cell line (3T3), "osteoblast-like" cell line (MC3T3-E1), and fresh human osteoblasts (HOB) which we cultured in our laboratory.

The purpose of this study was to evaluate and compare the diagnostic performance of stereolithography vs workstation-based three-dimensional (3D) reformations in intra-articular calcaneal fractures. A total of 30 intra-articular calcaneal fractures were examined using standard radiographs, coronal CT scans, and 2D and 3D reformations. The CT data were transferred to an outside institution, and stereolithograms were produced from photopolymer resin employing a laser beam system.

Jumping from bridges or cranes while secured by an elastic rope is called bungee jumping, and it is an increasingly popular sport. We report on two bungee jumpers who suffered from symptoms of acute venous stasis in the head. These included skin edema, purpura-like bleeding in the face and the conjunctiva, dizziness, confusion and, in one case, transient visual problems.

Severe crush injuries of lower limbs with loss of bone and soft-tissue need a clear concept of treatment. After resuscitation the examination and restitution of the injured limbs blood supply has absolute priority. Function of the tibialis posterior nerve plays an important role in the decision-making between amputation or reconstructive procedure.
