There is still some controversy about the reduction of unilateral and bilateral facet dislocations in the cervical spine. We have reviewed the notes and radiographs of 210 such patients; reduction was attempted by manipulation under anaesthesia (MUA) in 91, and by rapid traction under sedation in 119, using weights up to 150 lb (68 kg). Our results suggest that early reduction in patients with neurological deficit gives the best chance of neurological recovery, that rapid traction is more often successful than MUA, and that traction is safer than MUA. We found that the use of heavy weights with close monitoring was safe and brought about reduction in an average time of 21 minutes. We recommend this technique for the reduction of all cervical facet dislocations.

Costoplasty can reduce the important cosmetic deformity of rib prominence in scoliosis but there are few objective reports of correction. We recorded the results of three objective methods of assessing back shape before and after short-segment costoplasty in 55 patients. We showed that significant improvement was maintained over a two-year follow-up period. Primary costoplasty at the time of scoliosis surgery (n = 35) achieved greater proportional correction than secondary costoplasty performed after fusion of the spine (n = 20). The rib segments removed at primary surgery provided enough bone for the autogenous graft; harvesting from the pelvis was unnecessary. We report a new classification of rib morphology which helps in planning the site and extent of costoplasty, and in predicting the possible correction.

The pre-operative lumbar spine radiographs of 200 consecutive patients who had undergone discectomy for prolapsed intervertebral disc were reviewed. Prolapse was recognized as bulging or sequestration of the disc with consequent root compromise. Measurement of the lumbar level of the interiliac line was shown to correlate with the level of disc prolapse and the incidence of transitional vertebrae at the lumbosacral junction was significantly higher than normal. A pathological value for the lumbosacral angle could not be identified.
