The purpose of this study is to provide a systematic review of the literature and assess outcome of our experience of Ilizarov Bone Transport in reconstruction for primary malignant tumours of bone (PMTB).

A systematic review of the literature for reported cases of primary reconstruction of PMTB using distraction osteogenesis was performed. All cases of distraction osteogenesis for primary reconstruction of PMTB in our institution were reviewed. Outcome was determined from retrospective review of case notes and radiology. Patients were contacted to define final status.

There are few cases of primary reconstruction of PMTB using Ilizarov method in the literature. Most reports relate to benign tumours or reconstruction of secondary deformities or non-union after tumour resection. At our institution we have treated 7 patients with bone defects resulting from excision of a PMTB. Mean age was 42.1 years (23–48). Tumours occurred in the tibia in 4 cases and the femur in 3 cases. Histologic diagnosis was chondrosarcoma in 3, malignant fibrous histiocytoma in 2, adamantinoma in 1 and malignant intraosseous nerve sheath tumour in 1.

All patients were assessed through the hospital sarcoma board and shown to have isolated bone lesions without metastases. Mean bone defect after resection was 13.1 cm (10–17). Mean frame time was 13.6 months (5–23). Mean follow-up was 46 months (15–137). Complications included pin infection, docking site non-union, premature fusion of corticotomy, soft tissue infection and minor varus deformity. There was one local recurrence of tumour at five months after resection, resulting in a through hip disarticulation. The other cases remain tumour-free with united, well-aligned bones and acceptable long-term function.

PMTB is rare and poses a major reconstructive dilemma. Distraction osteogenesis provides an effective method of biologic reconstruction in selected cases, and good outcomes can be achieved.

A systematic literature review of distraction osteogenesis (DO) for the primary reconstruction of bone defects following resection of primary malignant tumours of long bones (PMTLB) is presented. Fewer than 50 cases were identified. Most reports relate to benign tumours or secondary reconstructive procedures. The outcomes of our own series of 7 patients is also presented (4 tibiae, 3 femora). All patients had isolated bone lesions without metastases and were assessed through the hospital sarcoma board. Mean follow-up was 59 months (17–144). Mean age was 42 years. Final histologic diagnoses were 3 chondrosarcoma, 2 malignant fibrous histiocytoma, 1 adamantinoma and 1 malignant intraosseous nerve sheath tumour. Mean bone defect after resection was 13.1cm (10–17) and bone transport was the reconstruction method in all. There was one local recurrence of tumour six months post-resection, necessitating amputation. Mean frame index for remaining cases was 30.9 days/cm (15.7–41.6). Complications included pin infection, docking site non-union, premature corticotomy union, soft-tissue infection and minor varus deformity. Six cases remain tumour-free with united, well-aligned bones and good long-term function. We conclude DO provides an effective biologic reconstruction option in select cases of PMTLB.

Purpose

According to the National Institute for Clinical Excellence (NICE) a risk assessment for venous thromboembolism (VTE) should be conducted on all patients undergoing elective orthopaedic surgery. We looked at the patient outcome undergoing elective Ilizarov surgery in terms of symptomatic VTE occurring during or after frame management.
