Case ReportsDevelopment of a solitary bone cyst--a report of a case suggesting its pathogenesis.
The origin and natural course of solitary bone cysts (SBC) still remain controversial. Knowledge of the process of cyst formation and enlargement would be helpful for investigating its pathogenesis. Only two papers have described a radiodense nidus of the diaphysis as a precursor. ⋯ This study reports a case in a patient with a tiny erosive lesion in the endosteal surface of the humeral metaphysis, which developed expansively into a typical large cyst over 6 years. Serial roentgenograms taken every year demonstrated the process of cyst enlargement. This is the first longitudinal study of a case with SBC documented from its onset.

Case ReportsTotal knee arthroplasty in patients with inherited dwarfism--a report of five knee replacements in two patients with Morquio's disease type A and one with spondylo-epiphyseal dysplasia.
In Morquio's disease and in hereditary spondylo-epiphyseal dysplasia of longer duration, malalignment, instability and unfavourable anatomy are generally the main surgical problems, but as these patients nowadays do not have a reduced life expectancy, it is worthwhile giving them a functional replacement for their severely deformed and painful knees. We report three patients with inherited dwarfism, in whom a replacement of the knee was performed.

Postoperative ambulatory level after hip fracture in the elderly predicts survival rate.
The purpose of this study was to evaluate whether the ambulatory level premorbid or at discharge reflected the survival rate better. Ambulatory level was retrospectively evaluated as a postoperative indicator of survival rate following operative treatment in 301 consecutive patients over 65 years old. ⋯ The postoperative ambulatory level at discharge reliably reflected the survival rate in the elderly after hip fracture, better than the premorbid ambulatory level. It is confirmed that the planning of the operation and rehabilitation to maintain the premorbid ambulatory level after hip fracture might be critical.

Case ReportsSynovial sarcoma with a large hematoma in the inguinal region.
We report the case of a patient with synovial sarcoma and a large hematoma of the inguinal region. The patient underwent tumor resection of the lower 2/3 of the acetabulum after preoperative chemotherapy. Twenty-four months after surgery, she is alive without any relapse and can walk without support.

Case ReportsStress fracture of the cuboid in an 8-year-old boy: a characteristic magnetic resonance imaging diagnosis.
A stress fracture of an 8-year-old boy diagnosed on magnetic resonance (MR) images is presented. Stress fractures of the cuboid are probably more common than previously reported. The diagnosis should be considered even when a history of trauma or chronic overload is absent. The MR appearance of the stress fracture was characteristic.
