ABSTRACT
Femoral neck fractures have been reported as a cause for failure in patients with a hip resurfacing arthroplasty. However, the incidence and management of fractures of the femoral shaft with an ipsilateral hip resurfacing arthroplasty is relatively absent in current literature. Although, the gold standard for the fixation of a closed femoral shaft fracture is with the use of an intramedullary nail, this can be a challenge in the presence of a hip resurfacing arthroplasty. We describe the case of anterograde intramedullary nail fixation for a femoral shaft fracture in a patient with an ipsilateral hip resurfacing arthroplasty in situ.

ABSTRACT
The role of chemonucleolysis as an alternative to disc surgery is still disputed. The authors conducted a prospective randomized controlled trial of chemonucleolysis and conventional disc surgery involving 92 patients with L4-5 or L5-S1 disc herniation who failed to respond to conservative treatment. There were 46 patients in each group, matched for demographic, clinical characteristics, and co-interventions. Independent examiners assessed patients before treatment, at 6 weeks after, 3 months after, and 1 year after treatment. A comprehensive method of outcome assessment involving physiological outcome, functional outcome, cost outcome, and psychological outcome was employed. Nine chemonucleolysis patients and one disc surgery patient required additional surgery for failure of initial treatment (P less than 0.02). The outcomes at 6 weeks and at 3 months were better in the surgical group, but at 1 year the differences were not significant. The authors conclude that chemonucleolysis as a minimally invasive technique produces inferior short-term results and offers no advantage over conventional discectomy.

In chemonucleolysis, accuracy of injection can be in doubt if the patient fails to respond. Discography preceding chemonucleolysis is associated with increased neurologic complications. Biplane fluoroscopy may fail to provide a clear picture on many occasions. The serum keratan sulphate levels were estimated in patients undergoing chemonucleolysis to ascertain if this could be used as a biochemical indicator to confirm accurate needle placement and to predict outcome. Serum keratan sulphate levels rose significantly following chemonucleolysis during the first 3 days (P less than 0.01). The rise was not significantly different, however, in patients who had improvement in their leg pain from those who did not improve (P = 0.35). Serum keratan sulphate level estimation before chemonucleolysis and at 24 or 48 hours following the procedure can be used to confirm accuracy of needle placement, but the rise in keratan sulphate is not predictive of the clinical outcome of the procedure.
