Case ReportsA primarily overlooked and incorrectly treated Essex-Lopresti injury: what can this lead to?
What result can one expect in treating an Essex-Lopresti lesion--a rare complex combination injury of the forearm consisting of a radial head fracture and a rupture of the interosseous membrane--which failed to be identified at first? ⋯ Years of illness and multiple corrective operations which only serve to limit the collateral damage caused by the wrong therapy strategy and ultimately only lead to restoration of moderate function. The crucial factor is an early diagnosis. Then a radial head prosthesis should first be implanted in an operation in order to prevent an additional proximal migration of the radius and to move the distal radioulnar joint into the proper anatomical position.

Case ReportsAnkle stiffness after Bosworth fracture dislocation of the ankle.
The purpose of this study is to review the result of patients with Bosworth fracture dislocation of ankle. ⋯ Early recognition and prompt reduction of the dislocated ankle is important in case of Bosworth fracture dislocation in order to prevent late complication. Closed reduction of dislocated ankle is usually not helpful and repeated attempts may be harmful. Emergency operation of open reduction and internal fixation is usually required to reduce the ankle joint without delay.

Total elbow arthroplasty in patients who have elbow fractures caused by gunshot injuries: 8- to 12-year follow-up study.
In this retrospective study, we aimed to present 8-12-year clinical and radiographic evaluation of total elbow arthroplasty in young patients who had open fractures due to gunshot injuries. ⋯ As a result, the patients in whom we implemented total elbow prosthesis in comminuted elbow fractures due to gunshot wounds seemed to get back into active life in the early period without any problem and it seemed that their pain disappeared and their functional capacity increased. In the long period, however, these values showed a distinct decrease with the same patients.

Drilling K-wires, what about the osteocytes? An experimental study in rabbits.
The function of osteocytes regarding osteonecrosis has been underestimated for a long time. Recently it has been suggested that apoptosis of osteocytes results in strong osteoclastic bone resorption. Death of osteocytes due to drilling may therefore increase the risk of K-wire loosening. The purposes of our in vivo study were to assess the minimal drill time needed to notice disappearance of osteocytes and to measure the distance of the empty osteocyte lacunae surrounding the drill tract in relation with the insertion time, directly and 4 weeks after drilling Kirschner (K-) wires into the femur and tibia of rabbits. ⋯ Although only drilling without cooling was studied, short drilling times may prevent the disappearance of osteocytes in case cooling is not used in clinical practice as is the case in percutaneous K-wire insertion.
