The aim of this study was to better quantify the role of delayed MRI scans in acute wrist injuries, and to assess the prevalence and distribution of multiple occult injuries of the wrist. A retrospective study was made of all patients who had been referred to the orthopaedic trauma clinic for a possible scaphoid fracture and with normal radiographs over a two year period. There were 110 patients. ⋯ The MRI scan is a useful tool in obtaining a definite diagnosis in acute wrist injuries. Among other findings, an occult scaphoid fracture was diagnosed on MRI in 2.7% of cases in this study. To conclude, in the majority of patients with persisting symptoms after two weeks following a wrist trauma, the cause of symptoms was pathology in other tissues in the wrist including soft tissues, other carpal bones and distal forearm.

The Thrust Plate Prosthesis is a femoral implant designed for total hip arthroplasty, based on the principles of physiologic loading of the metaphysis of the proximal femur, and preserving the bone stock. This study presents the long-term clinical and radiological results of 34 patients with 36 Thrust Plate Prostheses. In a retrospective analysis, we investigated the reoperation-free survival as well as the clinical and radiological results. ⋯ The major complaint was pain at the lateral side of the hip (44%). Radiolucencies did not exceed 1 mm, but 35% of the hips showed resorption of the cortex directly under the thrust plate, together with cancellous bone hypertrophy at the calcar, noted in 97%. Because of the relatively high reoperation-free survival and favourable radiological results, the Thrust Plate Prosthesis appears as a possible alternative to stemmed total hip arthroplasty, especially in relatively young patients.
