Total hip arthroplasty using an uncemented femoral component with taper design: outcome at 10-year follow-up.
The aim of this study was to assess the clinical and radiological outcome of the cementless-system (CLS) femoral component designed by Spotorno with a taper design. Ninety-four patients (107 hips) were operated on from January 1987 to December 1988. The female/male ratio was 2/1, the mean age was 51 years (range 20-77 years). ⋯ In all of these hips, the Mecron cup had been used. At a mean follow-up of 10 years, the results of the CLS femoral component are comparable with those of modern techniques of cementing in primary total hip arthroplasty and with the long-term outcomes of other uncemented stems with tapered design. The long-term fixation of the cup remains an unsolved problem.

We report a case of a nerve sheath ganglion of the ulnar nerve at the canal of Guyon. This case involved a ganglion which was confined to the epineurium of the ulnar nerve. and it was completely excised without any damage to the nerve fiber. A nerve-sheath ganglion is rare, but it should be considered in the differential diagnosis of any tumor which is causing neural disturbance.

We present the outcome of a mould arthroplasty implanted for a congenital hip dysplasia in 1955 to revise a previous cup arthroplasty. This type of prosthesis, which has been developed on the basis of the concept of Smith-Peterson, by Prof. Marino-Zuco in Rome in the early 1940s, showed excellent results and was widely used until the advent of Charnley low-friction arthroplasty.

Case ReportsA rare case of osteoporotic spine fracture associated with epidural lipomatosis causing paraplegia following long-term cortisone therapy.
Cushing's syndrome is frequently associated with osteoporosis. Therefore, the incidence of osteoporotic spine fractures is significant. They are a rare cause of paraplegic syndromes. ⋯ Our experience suggests that care should be taken before operative treatment of patients with pathological fractures in combination with Cushing's syndrome. In addition to vertebral fractures, epidural lipomatosis has to be taken into consideration. Those patients with neurological deficits have to be treated by an extensive laminectomy.

A patient suffering from severe hemophilia combined with a large pseudotumor of his left thigh is presented, and the case history discussed. The occurrence of this tumor in hemophilia is considered with respect to the clinical, radiological, and laboratory findings.
