Endoprosthetic replacement of the pelvis is one of the most challenging types of limb-salvage surgery, with a high rate of complications. In an attempt to reduce this and build greater versatility into the
Resection of a primary sarcoma of the diaphysis
of a long bone creates a large defect. The biological options for reconstruction
include the use of a vascularised and non-vascularised fibular autograft. The purpose of the present study was to compare these methods

1. Absence of a thumb, whether congenital or due to injury, is a severe disability. Reconstructive surgery has much to offer. 2. Pollicisation is the most satisfactory method, being the only means of providing a thumb with normal tactile sensibility. The importance of this has often been overlooked and has been emphasised by Moberg (1958). Pollicisation offers also the best functional and aesthetic results. When applicable, the neurovascular pedicle technique of Littler is the one of choice. It is indicated in group 2 cases associated with a partly amputated finger, when this is swung on to the thumb stump, and for patients in groups 3 and 4 when the normal index finger is used. If this method is not feasible a staged pollicisation may be used instead. 3. The Gillies method of thumb lengthening has a more limited application, but it is valuable in selected cases. 4.
The use of a navigation system in musculoskeletal tumour surgery enables the integration of pre-operative CT and MRI images to generate a precise three-dimensional anatomical model of the site and the extent of the tumour. We carried out six consecutive resections of musculoskeletal tumour in five patients using an existing commercial computer navigation system. There were three women and two men with a mean age of 41 years (24 to 47).
We describe a consecutive series of five patients with bone or soft-tissue sarcomas of the elbow and intra-articular extension treated by complex soft tissue, allograft bone and prosthetic joint replacement after wide extra-articular en bloc excision. All had a pedicled myocutaneous latissimus dorsi rotation flap for soft-tissue cover and

The results of proximal humeral replacement following trauma are substantially worse than for osteoarthritis or rheumatoid arthritis. The stable reattachment of the lesser and greater tuberosity fragments to the rotator cuff and the restoration of shoulder biomechanics are difficult. In 1992 we developed a prosthesis designed to improve fixation of the tuberosity fragments in comminuted fractures of the proximal humerus. The implant enables fixation of the fragments to the shaft of the prosthesis and the diaphyseal fragment using screws, washers and a special toothed plate. Between 1992 and 2003 we used this technique in 50 of 76 patients referred to our institution for shoulder
Our objectives were to establish the envelope of passive movement and to demonstrate the kinematic behaviour of the knee during standard clinical tests before and after
We randomised 31 patients with acute tears of the anterior cruciate ligament (ACL) to receive either early (within 2 weeks) or delayed (8 to 12 weeks)
We report our early experience with the use of
a new prosthesis, the Modular Hemipelvic Prosthesis II, for reconstruction
of the hemipelvis after resection of a primary malignant peri-acetabular
tumour involving the sacroiliac joint. . We retrospectively reviewed the outcome of 17 patients who had
undergone resection of a pelvic tumour and
The aim of this study was to evaluate the functional
and oncological outcome of extracorporeally irradiated autografts
used to reconstruct the pelvis after a P1/2 internal hemipelvectomy. The study included 18 patients with a primary malignant bone
tumour of the pelvis. There were 13 males and five females with
a mean age of 24.8 years (8 to 62). Of these, seven had an osteogenic
sarcoma, six a Ewing’s sarcoma, and five a chondrosarcoma. At a
mean follow-up of 51.6 months (4 to 185), nine patients had died
with metastatic disease while nine were free from disease. Local
recurrence occurred in three patients all of whom eventually died of
their disease. Deep infection occurred in three patients and required
removal of their graft in two while the third underwent a hindquarter
amputation for extensive flap necrosis. The mean Musculoskeletal Tumor Society functional score of the
16 patients who could be followed-up for at least 12 months was
77% (50 to 90). Those 15 patients who completed the Toronto Extremity
Salvage Score questionnaire had a mean score of 71% (53 to 85). . Extracorporeal irradiation and re-implantation of bone is a valid

problem faced by the orthopaedic surgeon. In the hand and wrist,
there are articular defects that are amenable to autograft reconstruction
when primary fixation is not possible. In this article, the surgical
