A comparison of conventional guidewire alignment jigs with imageless computer navigation in hip resurfacing arthroplasty.

Background: Correct positioning of the initial femoral guidewire is vital in order to prepare the femoral head properly for hip resurfacing. The purpose of the present investigation was to determine the accuracy and precision of the placement of the initial femoral guidewire with use of conventional alignment jigs and to compare the results with those of imageless computer navigation.

Methods: Five commercially available jigs (two lateral pin jigs, two neck centering jigs, and one head planing jig) were obtained.

The accuracy of digital templating in uncemented total hip arthroplasty.

We analyzed the reproducibility and reliability of computer templating in primary uncemented total hip arthroplasties as compared to standard onlay templating techniques with hardcopy radiographs from a digital source. Digital templating showed good intraobserver and interoberserver reliability with intraclass correlation coefficient values greater than 0.7.

Assessment of accuracy and reliability in preoperative templating for hip resurfacing arthroplasty.

The current study investigated the accuracy and reliability of hip resurfacing component selection based on digital preoperative templating. Four surgeons made a template of preoperative radiographs on 2 occasions for acetabular and femoral components in 50 randomly selected hip resurfacing patients. Component selection reliability was variable among surgeons (kappa = 0.

Short-term outcomes of total hip arthroplasty after complications of open reduction internal fixation for hip fracture.

Failed open reduction internal fixation (ORIF) of the proximal femur can render patients severely disabled. This study analyzed the short-term functional results and complications of total hip arthroplasty (THA) for complications of ORIF after hip fracture. A retrospective arthroplasty database review identified 36 patients treated with a THA for complications of ORIF of the hip.
