Comparative Study
Clinical implication of subgrouping in valgus femoral neck fractures: comparison of 31-B1.1 with 31-B1.2 fractures using the OTA/AO classification.
This study aimed to identify the clinical implications of valgus-impacted femoral neck fractures and compare fractures with >15-degree angle of impaction (31-B1.1) against fractures with <15-degree angle of impaction (31-B1.2). ⋯ Therapeutic level III.

Comparative Study
The effect of fracture pattern stability on implant loading in OTA type 31-A2 proximal femur fractures.
Internal fixation of OTA type 31-A2 proximal femoral fractures can be performed with either a sliding hip screw and side plate (SHS-P) or a sliding hip screw and intramedullary nail (SHS-IMN). Controversy exists as to which is the best implant for these types of fractures. The primary aim of this study was to investigate the stability of 31-A2 fractures as a function of loss of medial cortical buttress. The secondary aim was to assess the influence of fracture stability on the different internal fixation constructs. ⋯ Type 31-A2 fractures become increasingly unstable with increased medial comminution (or fragment size). SHS-P constructs were more load sharing than SHS-IMN constructs. These findings may help guide the surgeon in choice of implant for a 31-A2 intertrochanteric fracture, leaning toward SHS-IMN for the more unstable fracture patterns.

Comparative Study
Femoral neck fracture after removal of the compression hip screw from healed intertrochanteric fractures.
To evaluate the incidence of femoral neck fracture (FNF) after removal of a compression hip screw (CHS) without trauma and to determine the risk factors for this type of fracture. ⋯ Prognostic level II.

Determining the rate of specific adverse events after volar plating performed for distal radius fractures. ⋯ Therapeutic level IV.

Clinical Trial
The effect of acute distal radioulnar joint laxity on outcome after volar plate fixation of distal radius fractures.
The objective of this study was to determine whether intraoperative laxity of the distal radioulnar joint (DRUJ) is associated with adverse postoperative outcomes after volar plate fixation of a distal radius fracture (DRF) and 4 weeks of immobilization. ⋯ Prognostic level I.
