We report the clinical and imaging features of a huge deep leiomyoma of the rectus abdominis treated surgically in an 84-year-old man. Hypotheses are put forward to elucidate the etiology of this enigmatic localization, apparently the first described in the literature.
The peroneus quartus is a supernumerary muscle of the lateral compartment of the lower leg. There are several variations of this accessory muscle, and its terminology is very confusing. The peroneus quartus is found with a frequency varying from 10 to 21.7% of observed individuals. It is rarely involved in pathologic processes of the foot and ankle. Only a few reports exist in the literature involving peroneus quartus in a "retromalleolar conflict" (lateral ankle stenosis), sometimes in association with longitudinal attrition and tears of the peroneus brevis. We present a novel case, together with a review of the clinical, anatomic, and radiologic references about this muscle, and we try to make order in classification and terminology of its different forms.
The authors comment on the experience acquired in the treatment of chronic osteomyelitis of the long bones with intramedullary reaming. The procedure is reserved for the femur and tibia with stage I chronic osteomedullary infection according to the Cierny-Mader classification. 2 A total of 36 patients were treated. Surgical treatment consists in reaming of the medullary canal and in its contra-opening with antiseptic solutions. Mean time for lavage is 6 days. Criteria for healing involves the absence of clinical, humoral, and radiologic signs of active medullary sites of infection. The percentage of healing was 83.2%, mean long-term follow-up was 2.9 years.
The Marchetti-Vicenzi elastic nail was used in the osteosynthesis of 15 diaphyseal or metadiaphyseal fractures of the humerus, 14 cases achieved consolidation, 1 resulted in nonunion. Surgical approach was always distal, transtricipital and the nail was always locked distally. In the cases that healed, the mean radiographic consolidation time was 90 days. There were no immediate postoperative complications.
Over the last few years an increased percentage of work-related and car accidents has led to a higher percentage of acetabular fractures. These injuries are among the most difficult to treat in orthopaedic surgery because of their anatomy and because of the consequent difficulty in surgical exposure. It was the purpose of this study to reveal the diagnostic and the therapeutic paths related to the treatment of these kinds of fractures, based on our experience. A total of 517 acetabular fractures were treated over 16 years; at present, better results are obtained with surgical treatment than with non-surgical treatment.
