Lateral meniscal cyst causing irreversible peroneal nerve palsy.

We report an unusual case of irreversible foot drop occurring secondary to a large lateral meniscal cyst. We discuss the presentation and management of this rare case and highlight some of the less common causes of foot drop.

Ossification of the femoral head at closed reduction for developmental dysplasia of the hip and its influence on the long-term outcome.

The management of developmental dysplasia of the hip, particularly the timing of closed reduction with regard to the presence of the femoral head ossific nucleus, is controversial. The clinical and radiological outcome was assessed in a strictly defined group of 48 hips in 42 patients with an average of 11.1 years follow-up. One hundred percent of patients had an excellent or good result at final follow-up; 8.3% showed evidence of avascular necrosis and six hips underwent further surgery after closed reduction. There was no relationship between the presence or absence of an ossific nucleus at the time of closed reduction and the final outcome. In this well-defined group, closed reduction is safe and provides excellent results in the long term.

Accelerated para-articular osteochondroma formation within the knee: a case report.

INTRODUCTION: Intra-articular osteochondroma and acoustic neuroma are rare entities. CASE PRESENTATION: We report the rare occurrence of a para-articular osteochondroma of the knee developing over short duration, 5 months, following minor injury. CONCLUSION: Predisposition to heterotrophic ossification after previous neurosurgery and a second acoustic neuroma may have accelerated the growth of this benign tumour. The development of these two rare entities suggests they may be associated.
