A vascularised fibular strut graft was used for anterior spinal fusion in 16 patients with spinal kyphosis. The procedure was abandoned in three because of difficulty in establishing a vascular anastomosis and in one because the grafted fibula dislodged two days after operation. One patient died after five days. Of the 11 remaining patients, there were seven males and four females. Their ages at the time of operation averaged 30.9 years (12 to 71). The number of vertebrae fused averaged 6.7 (5 to 9) and the length of fibula grafted averaged 10.9 cm (6.5 to 18). Average follow-up was 54 months (27 to 84). Bone union occurred at both ends of the grafted fibula in all 11 patients, with an average time to union of 5.5 months (3 to 8). We did not see a fracture of the grafted fibula. Two patients had postoperative complications; the graft dislodged in one and laryngeal oedema occurred two days after operation in the other. A vascularised fibular strut graft provides a biomechanically stable and long-standing support in spinal fusion because the weak phase of creeping substitution does not take place in the graft

Aims

Patients with differentiated thyroid carcinomas (DTCs) have a favourable long-term survival. Spinal metastases (SMs) cause a decline in performance status (PS), directly affecting mortality and indirectly preventing the use of systemic therapies. Metastasectomy is indicated, if feasible, as it yields the best local tumour control. Our study aimed to examine the long-term clinical outcomes of metastasectomy for SMs of thyroid carcinomas.

Objective. To evaluate functional and oncological outcomes following resection of sacral tumours and discuss the strategies for instrumentation. Introduction. Primary malignant tumours of the sacrum are rare, arising from bony or neural elements, or bone marrow in haematological malignancies. Management of such lesions is dictated by anatomy and the behaviour of tumours. Three key issues which arise are the adequacy of tumour resection, mechanical stabilisation and the need for colostomy. Stabilisation is often extensive and can be challenging. Methods. A retrospective review of the surgical management of primary malignant sacral tumours from 2004 - 2009. Results. The study included 46 patients (34 males, 12 females) with an average age of 49 (range 7 – 82). Median duration of symptoms before presentation was 26 months. 25 patients (54%) underwent surgical resection. 8 underwent instrumented stabilisations with fibula strut graft vs. 17 uninstrumented. Mechanical failure of stabilisation was noted in 75% over the follow up period but only one required revision surgery. Colostomy was performed in 10 patients (40%). Mean follow post-operatively was 19.0 months. Wound healing problems were present in 5/25 (20%). There was no difference in infection rates between definitive surgery with and without colostomy. There was one peri-operative death. Local recurrence occurred in 12%(3/25) of operated patients although follow-up period was noted to be short. Conclusions. Mechanical stabilisation for extensive lesions in the sacrum are particularly challenging in tumour surgery. Despite radiological failure in 7/8 instrumented stabilisations, patients were relatively asymptomatic and only 1/8 required revision stabilisation surgery. Ethics approval:. None: Audit.

To evaluate functional and oncological outcomes following resection of primary malignant bone tumours. Primary malignant tumours of the sacrum are rare, arising from bony or neural elements, or bone marrow in haematological malignancies. Management of these lesions is dictated by anatomical considerations and the behaviour of tumours. The three key issues which arise are the adequacy of tumour resection, mechanical stabilisation and the need for colostomy. A retrospective review of the surgical management of primary malignant sacral tumours from 2004 - 2009. The study included 46 patients (34 males, 12 females) with an average age of 49 (range 7 – 82). Median duration of symptoms before presentation was 26 months. 10 patients had inoperable tumours at presentation. 6 patients had chemotherapy. 2 patients opted for palliative radiotherapy. 1 patient was unfit for surgery. 25 patients (54%) underwent surgical resection. 8 underwent instrumented stabilisations with fibula strut graft vs. 17 uninstrumented. Colostomy was performed in 10 patients (40%). Mean follow post-operatively was 19.0 months. Wound healing problems were present in 5/25 (20%).
