We report here three fully documented cases of periosteal chondroma diagnosed and treated in our hospital. There have been few references since Lichtenstein first described this condition as a separate tumour, and none of them concerned children under 10 years old. deSantos accurately describes the radiological features of the tumour. ⋯ The study included a previous histological examination in two cases and a follow-up in all of them. From this study we learned that invasive diagnosis procedures are unnecessary as we could follow the behaviour and evolution of this cartilaginous benign tumour for a long period of time.

Case ReportsCarpal tunnel syndrome caused by an idiopathic calcified mass.
This is a case report of carpal tunnel syndrome caused by an idiopathic calcareous lesion within the carpal canal. The median nerve was trapped between the transverse carpal ligament and the calcified mass. The mass was predominantly composed of calcium phosphate. Surgical release of the transverse carpal ligament and removal of the calcareous mass relieved the symptoms.

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.

Case ReportsHypoplasia of bilateral humeral trochlea associated with bilateral ulnar nerve palsy.
We document a case of bilateral ulnar nerve palsy that developed in an 27-year-old Japanese man who had bilateral hypoplasia of the humeral trochlea. Surgical management produced good results regarding the ulnar nerve palsy. ⋯ There have been no reports outside Japan. Whether this deformity occurs only in persons of Japanese extraction or is simply overlooked by foreign surgeons is an interesting question.

Case ReportsIsolated palmar dislocation of the distal radioulnar joint in a football player.
Palmar dislocation of the distal radioulnar joint without concomitant fracture of the radius or ulna is an uncommon injury. We report one case in a college football player. This case was unusual in that open reduction was required 2 days after the injury because of an unsuccessful closed reduction.
