The anterior supine approach for total hip arthroplasty (THA) offers the advantage of operating through a true intravascular and intranervous plane, but it places the lateral femoral cutaneous nerve at risk. The purpose of this study was to identify the incidence of and impairment relating to injury of the lateral femoral cutaneous nerve. We performed a retrospective chart review of 81 hips undergoing anterior supine THA from November 2005 through May 2007 to determine operative time, estimated blood loss, fluoroscopic time, type of anesthesia used, intraoperative complications, and postoperative systemic and wound complications. Postoperative radiographs were evaluated for leg-length discrepancy, acetabular inclination and anteversion, and femoral stem position. Patients were reassessed at 6 weeks, 3 months, 6 months, 1 year, and 2 years. At each visit, patients were questioned about numbness or paresthesias in the distribution of the lateral femoral cutaneous nerve; if present, the patient outlined the area with a marking pen. This area was photographed, and data were collected. No hip had frank numbness; 12 hips (14.8%) had paresthesias. For those 12, symptoms resolved in 4 by 6 months, in 6 by 1 year, and in 10 (83.3%) by 2 years; 2 remained unresolved. No significant difference was found between patients with and without paresthesias or between patients with resolved or unresolved paresthesias. Impaired sensation did not appear to affect functional outcome or Harris Hip Score. Incision position, dissection plane, retractor placement, tension and soft tissue handling, and surgeon experience may affect incidence of injury to the lateral femoral cutaneous nerve.

The objective of this study was to determine if hospitalist consultation during admission for hip fracture results in improved treatment for osteoporosis. This was a retrospective chart review, carried out in a university-based academic hospital. Administrative discharge data was used to identify patients discharged between 1 September 1999 and 1 September 2001, discharged with the diagnosis of hip fracture. Eighty-two patient charts were reviewed after exclusion for traumatic and pathologic fractures. Treatment for osteoporosis consisted of medications recommended by the National Osteoporosis Foundation (NOF), including calcium (+/-vitamin D), estrogen, raloxifene, calcitonin, alendronate and risedronate. Osteoporosis treatment improvement was defined as the addition of a medication for osteoporosis that strengthened treatment. Twenty-nine percent of patients in our study received treatment for osteoporosis at the time of discharge from the hospitalization for hip fracture. While 20% received calcium, only 7% received a bisphosphonate. Twelve percent received improvement in osteoporosis treatment from admission to discharge. Those that received hospitalist consultation did not have a significant improvement in osteoporosis treatment (P=0.314), but had significantly more co-morbid illnesses and were significantly older than those receiving no consultation (P<0.05). Identification of osteoporosis as a medical problem was significantly associated with osteoporosis treatment (P<0.05). Potential barriers to hospitalist consultation's effect on osteoporosis treatment included patient age and co-morbidities. Further research is needed to identify and overcome barriers to effective osteoporosis treatment in patients with fractures.

The early results associated with a new generation of hip resurfacing devices are promising. The anterolateral approach affords the surgeon excellent exposure with the advantage of increased hip stability and potentially improved vascular supply of the femoral head as compared with the posterior approach.
