In 1999, we developed a technique for biological
reconstruction after excision of a bone tumour, which involved using
autografts of the bone containing the tumour treated with liquid
nitrogen. We have previously reported the use of this technique
in 28 patients at a mean follow up of 27 months (10 to 54). In this study, we included 72 patients who underwent reconstruction
using this technique. A total of 33 patients died and three were
lost to follow-up, at a mean of 23 months (2 to 56) post-operatively,
leaving 36 patients available for a assessment at a mean of 101
months 16 to 163) post-operatively. The methods of reconstruction included
an osteo-articular graft in 16, an intercalary in 13 and, a composite
graft with prosthesis in seven. Post-operative function was excellent in 26 patients (72.2%),
good in seven (19.4%), and fair in three (8.3%) according to the
functional evaluation system of Enneking. No recurrent tumour occurred
within the grafts. The autografts survived in 29 patients (80.6%),
and the rates of survival at five and ten years were 86.1% and 80.6
%, respectively. Seven of 16 osteo-articular grafts (44%) failed
because of fracture or infection, but all the composite and intercalary
grafts survived. The long-term outcomes of frozen autografting, particularly using
composite and intercalary grafts, are satisfactory and thus represent
a good method of treatment for patients with a sarcoma of bone or
soft tissue. Cite this article:
We studied the safety of external fixation during post-operative chemotherapy in 28 patients who had undergone distraction osteogenesis (17, group A) or vascularised fibular grafting (11, group B) after resection of a tumour. Four cycles of multi-agent post-operative chemotherapy were administered over a mean period of 14 weeks (6 to 27). The mean duration of external fixation for all patients was 350 days (91 to 828). In total 204 wires and 240 half pins were used. During the period of post-operative chemotherapy, 14 patients (11 in group A, 3 in group B) developed wire- and pin-track infection. A total of ten wires (4.9%) and 11 half pins (4.6%) became infected. Seven of the ten infected wires were in periarticular locations. External fixation during post-operative chemotherapy was used safely and successfully for fixation of a vascularised fibular graft and distraction osteogenesis in 27 of 28 patients. Post-operative chemotherapy for malignant bone tumours did not adversely affect the ability to achieve union or cause hypertrophy of the vascularised fibular graft and had a minimal effect on distraction osteogenesis. Only one patient developed osteomyelitis which required further surgery.
