Clinical Trial
Correlation between inter-vertebral disc morphology and the results in patients undergoing Graf ligament stabilisation.
Previous studies have shown Graf ligament stabilisation procedure to give mixed results in the short to medium term. The aim of this study was to correlate the pre-operative state of the disc, multifidus muscles, age of the patient, levels operated and the clinical outcome after a mean follow-up of 47 months. ⋯ The indications of Graf ligament stabilisation procedure are not clear. Further work is necessary to clearly identify the indication for the procedure.

Morsellized bone-graft handling during spine surgery to get vertebral fusion can be a slow, laborious and time-consuming procedure. It is not absolutely exempt from complication risk. An easy, quick and inexpensive alternative technique is described.

Comparative Study
Fracture dislocations of the cervical spine: a review of 106 conservatively and operatively treated patients.
We compared clinical outcomes following conservative treatment of subaxial fracture dislocations of the cervical spine and posterior fusion using bone grafts and interspinous Roger's wiring (Bohlman modification). We reviewed 106 patients: 51 were treated primarily surgically, and 55 treated conservatively served as historical controls. Those patients who neurologically recovered at least one Frankel grade had on average less displacement on discharge (1.3 mm vs 3.1 mm, p=0.04). ⋯ Late neck pain correlated with residual displacement ( p=0.04) and was more common in the conservatively treated patients ( p=0.01). Time in hospital was shorter in the group with posterior fusions, and complication rates were similar to those found after conservative treatment. A significant number of the conservatively treated patients developed kyphotic deformity, and 29% needed later surgery because of chronic instability or unacceptable anatomical results.

A retrospective follow-up study of patients who, having undergone instrumented posterior spinal fusion for scoliosis, experienced late infection and then underwent either implant removal alone or implant removal and instrumented refusion. We conducted this study to determine whether it is possible to avoid loss of correction by a single-stage implant removal and reinstrumentation procedure. There have been a few reports of late-appearing infections after spinal instrumentation. ⋯ Thus, the thoracic Cobb angle was 28+/-16 degrees (range 0-55 degrees ) in the RI&F group versus 42+/-15 degrees (21-80 degrees ) in the HR group, and the lumbar Cobb angle was 22+/-11 degrees (10-36 degrees ) in the RI&F group versus 29+/-12 degrees (13-54 degrees ) in the HR group. The results of our study demonstrate that wound healing is usually uneventful after instrumentation removal for late infection, also when patients undergo instrumented refusion in a one-stage procedure. Reinstrumentation appears to achieve permanent correction of scoliosis.

A retrospective analysis of long-term follow-up results more than 10 years after a standard nucleotomy for lumbar disc herniation with the Love method was done to determine the effectiveness of this procedure. Nucleotomy according to Love was the standard treatment for lumbar disc herniation before the various minimally invasive alternatives were recently introduced. Without long-term follow-up analysis of Love operations, evidence-based evaluation of those new methods is impossible. ⋯ Patient overall satisfaction with the results of the standard nucleotomy was high. The disc height of the operation site significantly decreased after surgery; nevertheless, this did not affect the clinical outcome. A standard lumbar nucleotomy according to Love is a safe and reliable method of treating selected patients with lumbar disc herniations.
