The purpose of this study is to present a series of soft tissue sarcomas requiring complex vascular reconstructions, and to describe their management and outcomes.

Soft tissue sarcomas are rare mesodermal malignancies accounting for approximately 1% of all cancers diagnosed annually. Sarcomas involving the pelvis and extremities are of particular interest to the orthopaedic surgeon. Tumours that encase and invade large calibre vascular structures present a major surgical challenge in terms of safety of excision with acceptability of surgical margins. Technical advances in the fields of both orthopaedic and vascular surgery have resulted in a trend towards limb salvage with vascular reconstruction in preference to amputation. Limb-salvage surgery is now feasible due to the variety of reconstructive options available to the surgeon. Nevertheless, surgery with concomitant vascular reconstruction is associated with higher rates of complications including infection and amputation. We present a case series of soft tissue sarcomas with vascular compromise, requiring resection and vascular reconstruction. We treated four patients (n = 4, three females, and one male) with soft tissue masses, which were found to involve local vascular structures. Histology revealed leiomyosarcoma (n = 2) and alveolar soft part sarcomas (n = 2). Both synthetic graft and autogenous graft (long saphenous vein) techniques were utilised. Arterial reconstruction was undertaken in all cases. Venous reconstruction was performed in one case. One patient required graft thrombectomy at one month post-operatively for thrombosis.

We present a series of complex tumour cases with concomitant vascular reconstructions drawn from our institution's experience as a national tertiary referral sarcoma service.

The aim of operative treatment for ankle fractures is to allow early movement after internal fixation. The hypothesis of this study was that early mobilisation facilitated by a removable cast after internal fixation of ankle fractures would improve functional recovery of patients compared with that after conventional immobilisation in a cast.

Sixty-two patients between the age of seventeen and sixty-five with ankle fractures that required operative treatment were randomly allocated to two groups: immobilisation in a non weight bearing below knee cast for six weeks or early movement in a removable cast (at two weeks after removal of sutures) for the following four weeks. The follow-up examinations which consisted of subjective (clinical, Olerud-Molander score, AOFAS score, SF 36) and objective (swelling measurement, x-ray) evaluations were performed at two, six, nine, twelve and twenty four weeks post-operatively. Time of return to work was recorded.

There were two post-operative complications in the group treated with immobilisation in cast; two patients had deep vein thrombosis (DVT). There was one superficial wound infection treated with oral antibiotics and two deep wound infections requiring removal of metal in the group treated with early movement in a removable cast. Patients in group two (early movement) had higher functional scores at nine and twelve weeks follow-up. They also returned to work earlier (63.7 days) compared with the ones treated in cast (94.9 days). There was no statistical difference in Quality of Life (SF-36 Questionnaire) at six months between the two groups.

Early movement with the use of removable cast after removal of sutures in operated ankle fractures decreases swelling, prevents calf muscle wasting, improves functional outcome and facilitates early return to work of patients. Our findings support the use of a removable cast and early exercises in selected, compliant patients after surgery of the ankle.
