We have reviewed seven cases of synovitis caused by date palm thorns, six involving the knee and one the ankle. Five were satisfactorily treated by thorough irrigation of the joint with normal saline, but two required arthrotomy and synovectomy. All made a full recovery.

In a five-year period, 153 feet in 101 patients were treated by a Wilson's osteotomy of the first metatarsal for hallux valgus. Postoperative support was provided by either a below-knee or a forefoot plaster, and was continued for either three weeks or six weeks. The results showed overall success in 91% with no significant difference between the four groups. We suggest that a forefoot plaster for three weeks is adequate support after a Wilson's osteotomy.

A simple procedure of using a Smillie knife to release the lateral patellar retinaculum and the capsule in the unstable patella syndrome is described. The syndrome includes recurrent dislocation, recurrent subluxation and acute dislocation of the patella. Arthroscopy, to exclude any other pathology such as chondromalacia patellae, is performed before proceeding to closed lateral release. The results of this procedure are as good as those after more major surgical procedures. In a small percentage of patients a second operation such as tibial tubercle transfer or patellectomy may be necessary, especially in patients with an underlying congenital abnormality; but in many patients this type of major surgery has proved unnecessary.
