BACKGROUND Chronic tears of the subscapularis tendon with or without associated tears of the supraspinatus and infraspinatus tendons may lead to pain and dysfunction of the shoulder. If conservative treatment fails and repair of the musculotendinous unit is impossible, transfer of the pectoralis major tendon can be attempted to substitute for lost(More)
PURPOSE To evaluate the effect of MR arthrography of the shoulder on diagnostic thinking and therapeutic decisions by orthopedic shoulder surgeons. MATERIAL AND METHODS Orthopedic surgeons completed a questionnaire before and after MR arthrography for 73 consecutive patients. The main indications were suspected rotator cuff abnormalities. The clinical(More)
Fractures of the ipsilateral femur after hip arthroplasty are a serious problem. In most cases, minimal trauma is responsible for the fracture. Predisposing factors, such as severe osteoporosis, loosening of the stem of the prosthesis, or cortex perforations, are often found. Such fractures occurred between 1979 and 1989 in 30 patients, i.e. 2.3% of our(More)
BACKGROUND Perioperative mortality and survival after esophagectomy have improved over the past 10 years. Although stage is the most powerful predictor of long-term survival, it remains unclear whether other factors influence prognosis. METHODS Between 1981-1991, 100 patients with esophageal carcinoma were uniformly treated by transhiatal esophagectomy(More)
In this study, a retrospective analysis of patients with trochanteric fractures fixed with a dynamic hip screw was performed (n = 238). Analysis of the complete X-rays (n = 115) revealed rotation of the head-neck fragment in 12% of the cases (n = 14). Patients with complex fracture types were more often affected by this complication (p < 0.05). The distance(More)
Owing to gradual aging of the population, the incidence of osteoporosis-related fractures of the proximal femur has increased. Trochanteric fractures are encountered in more than 50% of hip fractures. In this study, a comparative epidemiological analysis of patients with trochanteric fractures treated in the orthopedic department of the university hospital(More)
In the case-control study of 118 women with autosomal trisomy identified at prenatal diagnosis and their 442 karyotypically normal matched controls, we found that there was no overall association between risk of trisomy and the presence of vaginal bleeding during pregnancy. However, a lengthy duration of bleeding appears to predict increased risk of trisomy.
It has been suggested that the maternal use of spermicidal contraceptives increases the frequency of certain congenital anomalies, including trisomy, but this issue is in dispute. This controversy led us to examine whether the use of spermicidal contraceptives is associated with an increased risk of fetal trisomy. A questionnaire concerning contraceptive(More)
