The early management of bilateral congenital popliteal webbing in a brother and sister is described. There was no familial history of webbing, but the maternal grandfather had a hare-lip. Although the sciatic nerve is so unfavourably placed in the web, correction of the flexion deformity can apparently be carried out safely after plastic repair of the skin by Z-plasty and excision of the fibrous web cord alone, without causing a traction paralysis. These cases appear to be unique in that the patients are siblings of different sex with identical congenital abnormalities of bilateral webbing, cleft palate and fistulae of the mucous membrane of the lower lip.
1. Sixty-five cases of medial fracture of the femoral neck treated by substitution of the head by an acrylic prosthesis have been studied. 2. In general, the long-term clinical results of prosthetic arthroplasty after fresh fractures have been disappointing. The method has given slightly better results in the treatment of old fractures. 3. In view of the almost perfect results obtained after successful Smith-Petersen nailing in the presence of an adequate blood supply to the femoral head, it seems unjustifiable to abandon this principle for immediate substitution with an acrylic femoral head. Nevertheless it is believed that an arthroplasty of this type is justified in fractures seen late, and in fresh subcapital fractures when the fracture is irreducible. If a prosthesis is to be used, more protection for the stump of the neck against the strain of weight bearing is essential; a simple head prosthesis is inadequate, and a head with either a neck extension or an intramedullary prolongation may give better results.
1. Three cases of a degenerative type of rheumatoid arthritis, with large cystic cavities filled with pus-like material, are described. They may arise from bursae or breaking-down nodules. 2. Four cases in which necrosis and subluxation complicated rheumatoid disease of the cervical column are recorded. 3. The pathogenesis of necrotic and cystic areas in rheumatoid arthritis is discussed.
