Long-term radiographic assessment of cemented polyethylene acetabular cups.

Unlabelled: In vitro studies demonstrating excessive wear in polyethylene cups sterilized using gamma irradiation and stored in air led to the abandonment of this sterilization technique. We evaluated the clinical wear performance of a metal femoral component on a polyethylene cup in a hip prosthesis from a selected subset of implants in a group of patients followed for at least 20 years and assessed the time dependency of variation in penetration rates. We measured penetration in 33 polyethylene cups in 25 patients who had a Charnley low-friction arthroplasty between 1982 and 1984.

Anatomy: a must for teaching the next generation.

Teaching anatomy to both undergraduate medical students and medical graduates is in the midst of a downward spiral. The traditional anatomy education based on topographical structural anatomy taught by didactic lectures and complete dissection of the body with personal tuition, has been replaced by a multiple range of special study modules, problem-based workshops, computers, plastic models and many other teaching tools. In some centres, dissected cadaver-based anatomy is no longer taught.

Cutaneous benign mixed tumor (chondroid syringoma) of the eyelid: clinical presentation and management.

Purpose: To describe the clinical presentation of cutaneous benign mixed tumor of the eyelid and its management options.

Methods: Periocular cases of cutaneous benign mixed tumor were gathered from members of an oculoplastics specialty Internet discussion group. A total of 9 patients are described in this retrospective, interventional case series.

Charnley low-friction arthroplasty: a worldwide retrospective review at 15 to 20 years.

This is a retrospective survivorship analysis review of 5089 Charnley low-friction arthroplasties performed as a primary procedure at 8 hospitals around the world before December 31, 1980. Data collected were simple with a well-defined endpoint: death or revision. There was no clinical or radiographic evaluation.

Review: the value of radiosurgery in oculoplastics.

Purpose: To present the value of radiosurgery in oculoplastic procedures.

Methods: My experience of 3 years and approximately 1000 oculoplastic procedures using radiosurgery was synthesized. The radiosurgical techniques that I have found useful are presented.
