PURPOSE To retrospectively evaluate the effectiveness of interstitial laser ablation (ILA) as a curative treatment of osteoid osteoma. MATERIALS AND METHODS Ethical review board approval was obtained for the retrospective study. Informed consent was waived. From June 1994 to June 2004, 114 patients (mean age, 22.3 years) suspected of having osteoid(More)
The development of rapid prototyping has evolved from the crude milled models to the laser polymerised stereolithographic models of excellent accuracy. The technology was advanced further with the recent introduction of fused deposition modelling and the 3-dimensional ink-jet printing technique in stereo-model fabrication. The concept of using a(More)
INTRODUCTION Fatigue and cognitive deficits are common symptoms affecting patients with multiple sclerosis. METHODS The effects of interferon beta on fatigue and cognitive deficits were assessed in 50 patients with relapsing multiple sclerosis (recruited at a single center). The pre-treatment assessments were performed on visits 1 and 2 (Months 0 and 3).(More)
This study investigated the errors of obtaining visually selected anatomic landmarks for use in the registration process in a passive optical non-image-based computer-assisted total knee arthroplasty system in 5 fresh frozen cadavers. The projected maximum errors in the femoral mechanical axis (due to registration errors of the center of the distal femur)(More)
We describe the treatment of an uncommonly late presentation of a recurrent parosteal osteosarcoma of the distal femur. The osteosarcoma had originally been detected 20 years earlier, and had been treated with wide excision and mega-prosthesis to reconstruct the femur. The tumour recurred in close proximity to the femur prosthesis and encased half the(More)
We have investigated the errors in the identification of the transepicondylar axis and the anteroposterior axis between a minimally-invasive and a conventional approach in four fresh-frozen cadaver knees. The errors in aligning the femoral prosthesis were compared with the reference transepicondylar axis as established by CT. The error in the identification(More)
We have reviewed all the cases of flap reconstruction following resection of a gynaecological malignancy at the Royal Marsden Hospital over 12 years from 1993 until 2005. Forty-six patients were identified who required 53 flaps. The predominant site of the primary tumour was vulva, accounting for 83% of the cases, with cervix, ovary, vagina and endometrium(More)
