Patellofemoral joint forces and pressures were measured in a cadaver model during intramedullary nailing of the tibia. A significant increase in contact pressures was found at the lateral facet of the patellofemoral articulation using the medial paratendinous approach (P = 0.01) and at the medial facet when using the trans-patellar tendon approach (P =(More)
Seventy-one patients undergoing revision hip surgery over a 5-year period from 1988 to 1993 had aspiration arthrography of the hip as a preoperative investigation. Sixteen hips were found to be infected at operation. Preoperative aspiration yielded positive cultures in 11 of these 16 hips. There was identical correlation between the organisms isolated on(More)
Intra-articular calcaneal fractures are associated with significant long-term morbidity, and considerable controversy exists regarding the optimum method of treating them. The contact characteristics in the intact subtalar joint were determined at known loads and for different positions of the ankle and subtalar joint, using pressure-sensitive film (Super(More)
Articular cartilage defects of the knee are a common condition diagnosed at arthroscopy. The management of these osteochondral lesions is controversial. We present our experience using carbon fibre implants to repair these defects in 18 patients. Eleven patients (61 per cent) had an osteochondral defect of the medial femoral condyle. Two patients had(More)
Mechanical efficiency, patient acceptability and minimal biochemical perturbation are important factors in the choice of lavage solution for bowel preparation. This prospective randomised trial of 59 patients compared a polyethylene glycol bowel lavage solution (Klean Prep) to a sodium picosulphate solution (Picolax) considering their efficacy from both(More)
Suction catheter tip contamination is a potential source of intraoperative inoculation of wounds with bacteria. The continuous passage of large quantities of air through a blood-soaked catheter tip during the course of surgical procedures can lead to significant contamination. This in turn may contribute to late wound infection due to inoculation of the(More)
We have conducted a prospective, double blind trial of low level laser therapy (LLLT) in musculoskeletal injuries to assess its efficacy. We assigned patients with a variety of painful skeletal soft tissue conditions to one of two treatment groups, treatment from a functional machine, placebo treatment from an inactive machine. Both machines were identical(More)
The purpose of this article is to report four patients with massive pulmonary embolism treated with percutaneous catheter and guidewire fragmentation and local administration of recombinant tissue plasminogen activator (r-TPA). Four patients with massive pulmonary embolism initially underwent pulmonary angiography. Thrombus fragmentation was performed with(More)
We assessed the outcome of patients with Vancouver type B2 and B3 periprosthetic fractures treated with femoral revision using an uncemented extensively porous-coated implant. A retrospective clinical and radiographic assessment of 22 patients with a mean follow-up of 33.7 months was performed. The mean time from the index procedure to fracture was 10.8(More)
