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.

Radiographic follow-up of traumatic spondylolisthesis of the axis is well documented in the literature. However, there is a paucity of studies regarding the long-term functional outcome of this type of injury.

To study the population, treatment and outcome following traumatic spondylolisthesis of the axis, we reviewed 36 consecutive patients presenting to our institution, a tertiary referral spinal trauma centre, over a 6-year period. We assessed: (a) the mechanism of injury, (b) the mode of treatment, (c) the radiographic classification using the Levine and Edwards system and (d) functional outcome using the Cervical Spine Outcomes Questionnaire (CSOQ) by BenDebba.

Of the 36 patients presenting there were 24 males and 12 females with a mean age of 46 (range18-82) years. The commonest mechanism of injury was road traffic accidents. There were 14 Type-I, 11 Type-II and 1 Type-IIA fractures. Twenty-seven patients were treated with halo vest immobilisation and nine were immobilised in a Minerva jacket. Four patients were converted from halo to Minerva because of pin failure. The mean duration of hospital stay was 10 (range 3-30) days. All fractures demonstrated radiographic union at a mean of 12 (range 10-16) weeks. There were no neurological complications. Upon review, all patients, whether Type-I or Type-II demonstrated low CSOQ scores approaching their pre-morbid status. However, Type-II fractures scored higher in 3 functional outcome categories when compared to Type-I fractures.

This unique study of an uncommon fracture shows for the first time a difference in the functional outcome scores of Type-II fractures of the axis when compared to Type-I fractures at a mean follow-up of 3 years and 10 months.
