Comparative Study
Biomechanical comparison of posterior pelvic ring fixation.
To determine relative stiffness of various methods of posterior pelvic ring internal fixation. ⋯ Under conditions of maximal instability with similar material properties between specimens, differences in stiffness of posterior pelvic ring fixation can be demonstrated. The choice of which method to use is multifactorial.

To compare the scoring efficacy of the injury severity score (ISS) and the new injury severity score (NISS) in predicting extended hospital length of stay (LOS) and intensive care unit (ICU) admission and to determine the effect of multiple orthopaedic injuries (MOI) on the discrepancies between the ISS and NISS and their impact on extended LOS and ICU admission. ⋯ MOI have a significant effect on trauma outcomes such as LOS and ICU admission. The recognition of this high-risk group is not possible using the traditional ISS alone from retrospective or prospective databases. Considering its easier calculation and better predictive power, it is suggested that the NISS should replace the traditional ISS in trauma outcome research.

The purpose of this study was to evaluate the mechanical stability of oblique interlocking screws in supplementing intramedullary nail fixation of high proximal tibial fractures. ⋯ The addition of oblique interlocking screws significantly improves the stability of a nailed proximal tibia fracture and provides comparable stability to a plate osteosynthesis.

To determine the incidence of pin tract infection.DESIGN Retrospective chart review. ⋯ Patients with hybrid external fixators had a similar risk of pin tract infection as patients who had unilateral fixators. The infection rate in the ring fixator group was significantly lower than the hybrid external and unilateral fixator groups.

The pelvic C-clamp was designed to provide posterior stability temporarily to pelvic ring injuries associated with massive venous hemorrhage in adult patients. Pediatric pelvic ring injuries are uncommon, but when unstable injuries occur they may be coupled with visceral injuries and lethal hemorrhage. 1, 2 Anterior external frame fixators have been described in the treatment of these injuries in pediatric patients with few adverse outcomes and good long-term results. ⋯ The pelvic C-clamp eliminated these problems, while providing fixation points that do not violate areas of cartilage or physeal growth. We present a case demonstrating that the pelvic C-clamp is a safe form of temporary fixation in a skeletally immature patient with a posterior pelvic ring injury associated with massive hemorrhage.
