RESUMO
Twenty selected patients with spondylolysis have been studied following apophyseal joint arthrography. In each instance a communication with the defect of the pars interarticularis was demonstrated by the extension of contrast medium from injection into the adjacent facet joint. The clinical and radiological features are described. The anatomical basis of the abnormality is presented using macroscopic and radiographic correlation from a dissected cadaveric specimen of spondylolysis. Sixty-five per cent of the patients experienced significant relief of pain symptoms when long-acting local anaesthetic was introduced into the facet joint.

Forty-five knees with tibial osteotomy for osteoarthrosis were studied at 5 to 10 years following surgery. Twenty-seven were graded excellent, eight good and ten poor. The best results were found in knees which maintained a Femoro-Tibial angle of 163 degrees--180 degrees whereas the poor results were associated with either under-correction at operation or late recurrence of deformity. The latter was closely related to pain. Provided that the initial deformity is adequately corrected and maintained, tibial osteotomy for osteoarthrosis of the knee gives good results which can last up to 10 years.
