ABSTRACT
We describe the case of a 58-year-old woman with AVN of the left trapezium which was treated surgically. This paper aims to review the etiologies leading to the pathology and the different therapeutic options. Avascular necrosis (AVN) of the carpal bones most commonly involves the lunate and the scaphoid . AVN of the trapezium is extremely rare. To our knowledge only 3 cases have been published in the literature so far and they were all treated differently.

The management of complicated distal femur fractures (DFF) of the elderly continues to pose a challenge. Knee mega-prosthesis are mostly used for Total knee arthroplasty revision and tumor resection surgery but they can be used for the treatment of complex knee fractures. The purpose of the present study is to examine the short- to mid- term outcomes of their use for complex DFF of the elderly. We retrospectively identified 4 patients with DFF AO33C3 on osteoporotic bone treated by total knee arthroplasty from September 2015 to October 2019. The average age at the time of the surgery was 79,5 years (range, 69 to 95 years). All patients were females and underwent a total knee replacement by one senior surgeon, with the OSS TM Orthopaedic Salvage System (Zimmer Biomet, Warsaw, Indiana, USA). Outcome measures included clinical outcome scores, radiological analyses, reoperation rate and complications. At an average follow-up of 2,3 years (range, 0,6 to 4,2 years), the average Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) was 17,25 (range, 7 to 37), the average Oxford knee score was 35,25 (range, 25 to 41) and the average pain Numerical Rating Scale (NRS) was 0,5 (range, 0 to 1). 3 Patients had postoperative anemia but no implant related complications has been reported. Complex DFF of the elderly treated with mega knee arthroplasty exhibit good clinical outcomes scores. The patients should be selected carefully as the complication rate found in the literature remains high.

Between June 1987 and December 2002, 237 cases of malleolar fractures were treated at Erasme Hospital using pneumatic stapling, alone or combined with another type of fixation. This retrospective study addresses 176 well-documented cases. The mean follow-up period was 36 months. The results indicate that pneumatic stapling is an effective technique with a very low rate of failure. Comminuted fractures are not a contraindication.
