Related Articles A New Technique for Radiographic Measurement of Acetabular Cup Orientation. J Arthroplasty. 2013 Jul 26; Authors: Derbyshire B, Diggle PJ, Ingham CJ, Macnair R, Wimhurst J, Jones HW Abstract Accurate radiographic measurement of acetabular cup orientation is required in order to assess susceptibility to impingement, dislocation, and edge loading wear. In this study, the accuracy and precision of a new radiographic cup orientation measurement system were assessed and compared to those of two commercially available systems. Two types of resurfacing hip prostheses and an uncemented prosthesis were assessed. Radiographic images of each prosthesis were created with the cup set at different, known angles of version and inclination in a measurement jig. The new system was the most accurate and precise and could repeatedly measure version and inclination to within a fraction of a degree. In addition it has a facility to distinguish cup retroversion from anteversion on anteroposterior radiographs.

Related Articles Age-Dependent Fracture Risk in Hip Revisions With Radial Impaction Grafting Technique: A 5-10 Year Medium-Term Follow-Up Study. J Arthroplasty. 2013 Jul 25; Authors: Chomrikh L, Gebuhr P, Bierling R, Lind U, Zwart HJ Abstract Radial impaction grafting (RIG) potentially improves the durability and reliability of cementing the femoral components in revision total hip arthroplasty (THA). In this multicenter, prospective study, 88 revision THAs (87 patients) with RIG technique were performed. The average follow-up time was 7.0years (range, 5.0-10.2). There were 14 femur fractures: 2 intraoperative, 5 within 3months after surgery, and 7 later in the postoperative stage (range, 5-84months). Sixteen patients were lost to follow-up and 20 died without stem re-revision. None of the patients have been re-revised for any reason during follow-up. Age was observed to be a significant factor for determining fracture risk. In conclusion, RIG can be considered a reliable surgical technique, especially for younger patients.

Related Articles Increased Complication Rate Following Conversion Total Hip Arthroplasty After Cephalomedullary Fixation For Intertrochanteric Hip Fractures: A Multi-center Study. J Arthroplasty. 2013 Jul 25; Authors: Pui CM, Bostrom MP, Westrich GH, Valle CJ, Macaulay W, Mont MA, Padgett DE Abstract Cephalomedullary devices (CMN) have become an increasingly popular for treatment of intertrochanteric hip fractures compared to sliding hip screw and side plate (SHS) devices. Failed fixation is often treated with conversion total hip arthroplasty (THA). We performed a multi-institutional study in which 60 patients with SHS devices and 31 patients with CMN devices were converted to THA. Harris Hip Score improved from 41.6 preoperatively to 83.6 at final follow-up in the SHS group and from 41.6 to 78.6 in the CMN group, with no significant difference between the groups (P=0.23). However, the complication rate in converted CMN patients was significantly higher at 41.9% compared with 11.7% (P=0.001) in converted SHS patients. Prior fixation with CMN may be associated with significantly higher complication rates during conversion.

Related Articles Do Larger Femoral Heads Improve the Functional Outcome in Total Hip Arthroplasty? J Arthroplasty. 2013 Jul 25; Authors: Allen CL, Hooper GJ, Frampton CM Abstract Use of larger diameter femoral heads has been popularised in total hip arthroplasty (THA). Recent studies have implicated larger femoral heads in early failure. We evaluated what effect the size of the femoral head had on the early functional outcome in order to determine the optimal head size for the maximal functional outcome. There were 726 patients who underwent elective THA and were divided into 3 groups according to head size then compared with respect to functional outcome scores and dislocation rates. This study failed to show that increasing the size of the femoral head significantly improved the functional outcome at 1year after total hip arthroplasty but that the use of a 36mm or greater femoral head did reduce the dislocation rate.

Related Articles Incidence of and Risk Factors for 30-Day Readmission Following Elective Primary Total Joint Arthroplasty: Analysis From the ACS-NSQIP. J Arthroplasty. 2013 Jul 25; Authors: Pugely AJ, Callaghan JJ, Martin CT, Cram P, Gao Y Abstract Recently, the government has moved towards public reporting of 30-day readmission rates after elective primary total knee (TKA) and total hip arthroplasty (THA). We identified 11,814 and 8105 patients who underwent primary TKA and THA from the 2011 ACS NSQIP. Overall readmission rates within 30-days of surgery were 4.6% for TKA and 4.2% for THA. Complications associated with readmission were predominantly wound infections, sepsis, thromboembolic, cardiac, and respiratory related. In TKA, multivariate analysis identified age (P=0.002), male gender (P=0.03), cancer history (P=0.008), elevated BUN (P=0.002), a bleeding disorder (P<0.001) and high ASA class (P<0.001) as predictors of readmission. In THA, obesity (P=0.008), steroid use (P=0.037), a bleeding disorder (P=0.002), dependent functional status (P=0.022), and high ASA class (P<0.001) predicted readmission. Understanding characteristics associated with readmission will be essential for equitable patient risk stratification.
