Related Articles Vitamin D Insufficiency in Patients With THA: Prevalence and Effects on Outcome. Clin Orthop Relat Res. 2013 Jul 19; Authors: Lavernia CJ, Villa JM, Iacobelli DA, Rossi MD Abstract BACKGROUND: The consequences of vitamin D insufficiency in the elderly remain controversial. The prevalence and potential effects of its chronic insufficiency on quality of life and physical function in patients undergoing THA have received little attention. QUESTION/PURPOSES: We determined (1) prevalence of preoperative vitamin D insufficiency in patients undergoing THA and (2) relationships of insufficiency to patient-perceived outcomes (PPOs) and hip scores.

Related Articles Mid-Term Outcomes in HIV-Positive Patients After Primary Total Hip or Knee Arthroplasty. J Arthroplasty. 2013 Jul 15; Authors: Lin CA, Takemoto S, Kandemir U, Kuo AC Abstract We hypothesized that infection rates following total joint arthroplasty (TJA) in those with the human immunodeficiency virus (HIV) without hemophilia or drug use would be similar to rates in HIV-negative patients. Records at an urban HIV referral hospital were searched for patients who underwent primary total hip and knee arthroplasty from 2003 to 2010. The primary outcome was revision for infection. 372 HIV-negative and 22 HIV-positive TJA patients met inclusion criteria. The HIV-positive group had more deep infections than the HIV-negative group (9.1% v 2.2%, P=0.102). There were no infections in those with AIDS-defining CD4 counts. Those with HIV may have a higher risk of developing a deep infection. A low CD4 count is not an absolute contraindication to TJA in HIV positive patients.

Related Articles Leaded Eyeglasses Substantially Reduce Radiation Exposure of the Surgeon's Eyes During Acquisition of Typical Fluoroscopic Views of the Hip and Pelvis. J Bone Joint Surg Am. 2013 Jul 17;95(14):1307-11 Authors: Burns S, Thornton R, Dauer LT, Quinn B, Miodownik D, Hak DJ Abstract BACKGROUND: Despite recommendations to do so, few orthopaedists wear leaded glasses when performing operative fluoroscopy. Radiation exposure to the ocular lens causes cataracts, and regulatory limits for maximum annual occupational exposure to the eye continue to be revised downward. METHODS: Using anthropomorphic patient and surgeon phantoms, radiation dose at the surgeon phantom's lens was measured with and without leaded glasses during fluoroscopic acquisition of sixteen common pelvic and hip views. The magnitude of lens dose reduction from leaded glasses was calculated by dividing the unprotected dose by the dose measured behind leaded glasses. RESULTS: On average, the use of leaded glasses reduced radiation to the surgeon phantom's eye by tenfold, a 90% reduction in dose. However, there was widespread variation in the amount of radiation that reached the phantom surgeon's eye among the various radiographic projections we studied. Without leaded glasses, the dose measured at the surgeon's lens varied more than 250-fold among these sixteen different views.

Related Articles Cost-effectiveness of low-molecular-weight heparin compared with aspirin for prophylaxis against venous thromboembolism after total joint arthroplasty. J Bone Joint Surg Am. 2013 Jul 17;95(14):1256-64 Authors: Schousboe JT, Brown GA Abstract BACKGROUND: There is controversy regarding the most appropriate strategy to prevent venous thromboembolism following total joint arthroplasty. Our objective was to estimate the lifetime costs, quality-adjusted life-years (QALYs), and costs per QALY gained using low-molecular-weight heparin compared with low-dose aspirin for two weeks after total knee or total hip arthroplasty in patients with no history of venous thromboembolism. METHODS: We used a Markov cohort model with health states of healthy after surgery, no postphlebitic syndrome after venous thromboembolism, postphlebitic syndrome after venous thromboembolism, and survival after intracranial hemorrhage to compare treatment with low-molecular-weight heparin or aspirin (160 mg) for fourteen days after total knee arthroplasty or total hip arthroplasty in patients with an age of fifty-five, sixty, sixty-five, seventy, seventy-five, eighty, or eighty-five years. We estimated lifetime costs, QALYs gained, and costs per QALY gained for both strategies, and applied a cost-effectiveness threshold of $100,000 (2010 U.S. dollars) per QALY gained.
