An extremely rare "transverse fracture" of the pelvis is presented. This fracture is not yet classified in currently used classifications of pelvic fractures. A fully detailed description of the fracture is given, along with a possible explanation of the mechanism of the injury.
Soft tissue ossification is a well-known phenomenon in various pathologic conditions. Myositis ossificans circumscripta refers to posttraumatic calcification of soft tissue, including various ligaments. However, posttraumatic calcification of ligaments in the pelvis is a rare complication described only anecdotally in the past. We present a rare case of posttraumatic calcification of the sacrotuberous ligament in a patient, several months after suffering a pelvic trauma. This is one of the differential diagnoses of soft tissue pain and tenderness after trauma.
This article presents our experience with 24 patients who had distal tibial fractures and were treated by percutaneous plate fixation. Distribution of the fractures according to the AO/OTA classification was as follows: five patients suffered from a 43 A type fracture, six from a 43 B type fracture, and 13 from a 43 C type fractures. Four of the fractures were open. Exclusion criteria included 43 C3 fractures and Gustilo III open fractures. All fractures showed radiographic signs of union enough to enable full weightbearing within an average time of 12.3 weeks. All patients showed a good range of motion (average dorsiflexion 12 degrees and average plantiflexion 18 degrees). Two fractures united with mal-union: one with an 8 degrees valgus deformity and another with a 7 degrees varus deformity. Both cases, which had a metaphyseal component, were treated by means of a "soft" (flexible and manually adjustable) AO 3.5 mm reconstruction plate. Except for one case of superficial infection, no infections were detected in any of the patients. The biological percutaneous plate fixation of distal tibial fractures with no extensive intra-articular involvement is a good soft tissue preserving technique. It provides a rigid and anatomical fixation in most cases. We conclude that type B fractures with one intact column can be fixed with either "soft" or "rigid" plates, and type A and C fractures with a metaphyseal component should be fixed with "rigid" plates (AO 4.5 mm Dynamic Compression Plate). In these fractures the reduction should be performed cautiously due to the tendency of sagittal plane mal-reduction.

BACKGROUND: As air travel increases and the number of commercial and non-commercial flights rises, so does the number of aircraft accidents. The improved safety standards of the aviation industry result in a growing number of survivors of aircraft crashes, but there are no management guidelines for the treatment of these survivors. OBJECTIVES: To present our experience in treating five survivors of a light aircraft crash that occurred in August 1995 near Jerusalem. RESULTS: All five survivors sustained vertebral column injuries, which was the only injury in most of the survivors. We discuss the mechanism of injury. CONCLUSIONS: Investigation of injuries' pattern in survivors of aircraft crash is important for establishing management protocols in trauma centers.
BACKGROUND: Femoral hip fractures are a common occurrence in the elderly. Of the various fracture patterns, intertrochanteric injuries have the lowest rate of complications. Case reports of ensuing subcapital fracture have all been linked to incorrect placement of fixation devices or to osteomyelitis, white cases of avascular necrosis have only been reported rarely in the literature and are considered to occur at the rare rate of 0.8%. OBJECTIVES: To check the incidence and outcome of AVN in intertrochanteric hip fractures. METHODS AND RESULTS: In a retrospective analysis of patients who had surgical treatment for intertrochanteric fractures. 10 patients (0.5%) underwent dynamic hip screw fixation for intertrochanteric fractures and subsequently developed painful AVN as their primary presentation. Three of these patients were also found to have subcapital fractures. On revision of the primary fixation no fault was found with nail placement. CONCLUSIONS: The reported rate of AVN may be understated since many patients have limiting factors that prevent them from consulting a physician when in pain, and one-third of these patients die within 2 years. Therefore, we suggest that hip pain following fixation of an intertrochanteric fracture should prompt the clinician to consider the rare possibility of AVN or subcapital fracture.
