Objective. To evaluate functional and oncological outcomes following sacral resection. Methods. Retrospective review of 97 sacral tumours referred to spinal or oncology units between 2004 and 2009. Results. 61 males, 37 females (average age of 47 (range 3 – 82). Average duration of symptoms 13 months. 17 metastatic disease, excluded from further discussion. Of the remainder 36/81(44%) underwent surgery – 21 excision, 9 excision and instrumented stabilisation, and 6 curettage. 13(16%) patients were inoperable - 8 advanced disease, 3 unable to establish local control, 2 recurrence. Colostomy was performed in 11/21(52%) patients who underwent excision. Deep wound infections in 6/21(29%). No difference in infection rates between definitive surgery with or without colostomy – 3/11(27%) vs. 3/10(30%). In the instrumented group, no colostomies were performed due to concerns about deep infection and none resulted (0/9). Radiological failure of stabilisation was noted in 7/9(78%). However, functionally, 3/9(33%) were mobilising independently, 3/9(33%) crutches, 2/9(22%) able to transfer and 1/9(11%) undocumented. Mean follow-up 25 months (range 0-70). Local recurrence in 9/36(25%) of operated patients. Metastasis occurred in 4/36(11%) and mortality 8/36(22%) although follow-up period was noted to be short. Conclusions. Results are comparable with current literature. Mechanical stabilisation for extensive sacral lesions is challenging. Despite radiological failure in 7/9 instrumented stabilisations, patients were relatively asymptomatic and only 1/9 required revision stabilisation surgery. By design none had colostomies and there were no deep infections

Aims

Vertebral body tethering (VBT) is a non-fusion technique to correct scoliosis. It allows correction of scoliosis through growth modulation (GM) by tethering the convex side to allow concave unrestricted growth similar to the hemiepiphysiodesis concept. The other modality is anterior scoliosis correction (ASC) where the tether is able to perform most of the correction immediately where limited growth is expected.

Aims

It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis.
