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.

To compare open reduction and internal fixation (ORIF) with total elbow arthroplasty (TEA) for intraarticular distal humerus fractures in women older than 65 years of age. ⋯ Using the Mayo Elbow Performance score, the outcomes of the 12 patients treated with ORIF were as follows: 4 excellent, 4 good, 1 fair, and 3 poor (cases that required conversion to TEA). Outcomes of the 12 patients treated with TEA were as follows: 11 excellent and 1 good. There were no fair or poor outcomes in the TEA group. No patients treated with TEA required revision surgery. We believe TEA to be a viable treatment option for distal intraarticular humerus fractures in women older than age 65. This is particularly true for women with associated comorbidities, such as rheumatoid arthritis, osteoporosis, and conditions requiring the use of systemic steroids.

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.

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.
