Lumbar discography, a useful modality for evaluating patients with lower back pain, is performed under fluoroscopy with posteroanterior and lateral fluoroscopic imaging. Despite use of fluoroscopy, needle placement into the L5-S1 disc may be difficult, especially in the presence of degenerative changes. We describe use of angled posteroanterior fluoroscopy with the fluoroscopy beam directed 30 degrees to 40 degrees caudally in a prone patient for clear visualization of the L5-S1 disc space. Use of this radiographic view aids in accurate needle placement and might decrease both procedure duration and fluoroscopic exposition.

Blood loss, operative time, and rate of complications were compared in 606 patients undergoing primary unilateral total hip arthroplasty with either spinal anesthesia (SA) or general anesthesia (GA). Patients were followed for 2 years after surgery. ⋯ Compared with patients receiving GA, patients receiving SA had higher hemoglobin levels on postoperative days 1 and 2 and a 20% lower total transfusion requirement. SA appears superior to GA for this procedure.

Heparin-induced thrombocytopenia (HIT) and heparin induced thrombocytopenia with thrombosis (HITT) ar rare complications associated with use of unfractionate heparin (UFH) or low-molecular-weight heparin (LMWH) HIT is a benign clinical condition characterized by a mil drop in platelet count with no clinical significance. HIT is an immune-mediated reaction associated with a wide spread "hypercoagulable" state resulting in arterial an venous thrombosis. ⋯ Orthopedic surger patients are at higher risk for developing HITT than are patients who receive prophylactic heparin for cardiovascular surgery or medical reasons. Therapy for patients suspected of having HITT should begin with immedi ate discontinuation of heparin in any form followed by pharmacologic inhibition with thrombin (e.g., recombinant hirudin [lepirudin], argatroban, danaparoid sodium).
