OBJECTIVE: To describe our experience using the anterior internal pelvic fixator (INIFX) for treating pelvic ring injuries. DESIGN: Case Series SETTING:: Level 1 Trauma Center PATIENTS:: Eighty-three patients with pelvic ring injuries treated with INFIX. Follow up avg. 35 months (range 12-80.33) INTERVENTION:: Surgical treatment of pelvic ring injuries included reduction, appropriate posterior fixation, and INFIX placement. OUTCOME MEASUREMENTS: Reduction using the pelvic deformity index (PDI) and pubic symphysis(PS) widening, Majeed functional scores, complications; infection, implant failure, heterotopic ossification (HO), nerve injury, and pain...

OBJECTIVES: Biomechanical studies of osteoporotic bone have used synthetic models rather than cadaveric samples because of decreased variability, increased availability, and overall ease of use of synthetic models. We compared the torsional mechanical properties of cadaveric osteoporotic bone with those of currently available synthetic osteoporotic bone analogues. METHODS: We tested 12 osteoporotic cadaveric humeri and 6 specimens each of 6 types of synthetic analogues...

OBJECTIVES: This study sought to examine fatigue characteristics of two polyaxial locking screw designs: locking cap (LC) and cross-threaded (CT). The goal was to compare LC and CT implants at 0, 10, and 15 degrees of angulation to determine the effect of locking mechanism on screw-plate interface failure. The hypothesis was LC implants would have superior fatigue properties in comparison to CT designs and that increased angulation of the screw would have a negative impact on the fatigue life of CT implants, but would not have any effect on LC implants...

: Marginal impaction of the acetabulum is typically accessible through fracture planes specific to the nature of the injury. Infrequently, however, incarcerated marginal impaction or free osteochondral fragments are not accessible through these existing fracture planes. As such, alternative methods to access these articular pieces must be considered to ensure adequate reduction. We describe an osteotomy of the posterior wall to access incarcerated fragments and marginal impaction of the acetabulum, enabling concentric articular reduction...

OBJECTIVES: The optimal treatment protocol for bicondylar plateau fractures remains controversial. Contrary to popular practice which favors a staged protocol in many high-energy fracture patterns, we have used early single-stage open reduction and internal fixation (ORIF) to treat these injuries whenever possible. The purpose of this study was to determine the complication rate as well as the functional and radiographic outcomes of this strategy. DESIGN: Retrospective Cohort study and prospective data collection...

OBJECTIVE: To determine 1) the reliability of the standard and modified RUST score in a sheep osteotomy model, and 2) the standard and modified RUST score that represents biomechanical union. DESIGN: The tibia cortices in a sheep osteotomy model treated by intramedullary nails were radiographically evaluated using standard and modified RUST scores. Scores that correlated with biomechanical union, based on the torsional stiffness of the contralateral tibia, were determined...

OBJECTIVES: It is recommended that the intraarticular component of a supracondylar distal femoral fracture be stabilized by a lag screw to create interfragmental compression. Generally, it is thought that lag screw fixation should precede any positional screw or locking screw application. This study compared three methods of maintaining inter-fragmentary compression after fracture reduction with a reduction clamp. METHODS: Intra-articular vertical split fractures were created in synthetic femora...

OBJECTIVE: The treatment of mid-shaft clavicle fractures has, in the last two decades, shifted markedly towards operative management. Prospective trials have defined accepted clinical and radiographic indications for the surgical management of clavicle fractures. This report documents three cases of clinically united angular malunion of the mid-shaft clavicle in young athletes that subsequently refractured to highlight angular deformity in the absence of displacement as a potential indication for surgical fixation...
