An unusual case of aneurysmal bone cyst in the metacarpal of a five-year-old girl is described. The lesion was initially diagnosed and treated as a simple bone cyst. Subsequently the affected metacarpal was excised and replaced by an autogenous fibular graft, with good results. A discussion of the pathogenesis of the lesion is given, with a review of the literature.
The circulating levels of sialic acid (N-acetylneuraminic acid) and glycosaminoglycans (GAGs) were measured in 69 patients with spinal disorders of orthopaedic interest (ankylosing spondylitis 17, osteofluorosis 6, idiopathic backache 10, osteoarthrosis 16, osteoporosis 20). The serum GAG levels showed no statistically significant change from control values in the five disorders investigated in the present study. Although osteoporosis and osteoarthrosis showed a decrease in serum sialic acid (SA) levels, the mean ratio (SA/GAG) demonstrated no change from control values. Idiopathic backache showed no difference in any of the parameters studied when compared with control values. Ankylosing spondylitis and osteofluorosis had a remarkable similarity in their clinical and radiological features, but a divergent mean value of ratio was noted. The mean ratio of both the conditions also showed a statistically significant difference from the control value. This suggests that the SA/GAG ratio can be used as a diagnostic test in ankylosing spondylitis.

Modified Phemister bone grafting consisting of the raising of an osteoperiosteal flap, bone petalling and a cancellous onlay graft for non-union of tibial shaft fractures was tried in 43 cases. Thirty-eight out of 43 fractures united after one bone grafting procedure, giving a success rate of 88%. The procedure can even be used in the presence of low-grade, active infection. This method of bone grafting is simple and has no significant complications. Knee motion recovers well but ankle and toe stiffness do not improve appreciably from the preoperative status. We recommend that Phemister grafting be performed early.
