[Osteochondritis dissecans].

Osteochondritis dissecans (OCD) is a disease of unknown etiology, characterized by separation of necrotic bone from its bony bed. While the juvenile form seen in patients with open physes has a 60-90% rate of spontaneous resolution, the adult form has virtually no chance of spontaneous healing. Plain X-rays are sufficient for the diagnosis, and magnetic resonance imaging (MRI) is essential for evaluation of disease progression and/or healing.

Glove punctures in major and minor orthopaedic surgery with double gloving.

We assessed the frequency of glove perforation during major and minor orthopaedic surgeries, in order to determine the efficacy of double gloving. A total number of 1528 gloves (622 inner and 906 outer) used in 200 procedures (100 major-100 minor), and 100 pairs of unused gloves were examined. Glove perforation rate, incidence among surgical team, location of perforation and duration of surgery were compared.

Bilateral staged total knee arthroplasty in obese patients.

Introduction: The purpose of this study was to compare the clinical and functional results and complications associated with staged bilateral total knee arthroplasty (TKA) performed 4-11 days apart during a single hospitalization in patients who were obese and patients who were not obese.

Methods: We retrospectively evaluated 48 (96 knees) patients who were obese and divided into two groups based on their body mass indices (BMI). Morbidly obese patients (group A1, BMI > or = 40 kg/m2) consisted of 21 patients (42 knees), and obese patients (group A2, BMI > or = 30 kg/m2) consisted of 27 patients (54 knees).

[Early results of kyphoplasty in osteoporotic vertebral compression fractures].

Objectives: We evaluated early results of kyphoplasty for osteoporotic vertebral compression fractures with regard to the level of pain, activity levels of patients, and radiographic restoration of the vertebra bodies.

Methods: Sixteen patients (4 males, 12 females; mean age 63 years; range 55 to 72 years) with osteoporotic vertebral compression fractures in the lumbar spine were treated with kyphoplasty. The procedure was performed at 21 levels, with a minimum of 3 ml (range 3 to 6 ml) of cement per level.

[Development of osteonecrosis after arthroscopic meniscal and chondral knee surgery: a report of five cases].

The development of osteonecrosis after arthroscopic surgery has been associated with meniscectomy, chondral surgery, and the use of thermal energy. This paper presents five cases, four of which fulfilled the temporal criteria for postarthroscopy necrosis, i.e.

Treatment of pelvic aneurysmal bone cysts in two children: selective arterial embolization as an adjunct to curettage and bone grafting.

Treatment options of aneurysmal bone cysts include complete resection, curettage, curettage with bone grafting, selective arterial embolization (as a primary treatment or preoperative adjuvant therapy), and percutaneous injection of fibrosing agent. Treatment in pelvic locations is difficult because of the relative inaccessibility of the lesions, the proximity of the lesions to neurovascular structures, and the vulnerability of the acetabulum. Herein, we present 2 pediatric cases of pelvic aneurysmal bone cysts successfully treated with curettage with bone grafting following preoperative selective arterial embolization.

[A case of pigmented villonodular synovitis of the elbow joint with bone invasion].

Pigmented villonodular synovitis is a benign proliferative disorder of the joint and of the tendon sheath synovium. It has a predilection for the lower extremities, particularly the knee and the hip. The elbow joint is rarely affected.
