Aims

Complete ruptures of the ulnar collateral ligament (UCL) of the thumb are a common injury, yet little is known about their current management in the UK. The objective of this study was to assess the way complete UCL ruptures are managed in the UK.

1. A forty-nine-year-old man had a chondrosarcoma arising from the body of the seventh thoracic vertebra. The tumour protruded into the mediastinum and also into the spinal canal where it displaced the spinal cord.

2. At operation all the seventh thoracic vertebra and parts of the sixth and eighth were removed together with the tumour. The thoracic spine was reconstructed by inserting two iliac bone-blocks between the cut bodies of the sixth and eighth vertebrae and by wiring two strong "A. O." plates to the transverse processes of the third to the sixth and the eighth to the tenth vertebrae.

3. The patient was nursed in a plaster-of-Paris bed for three and a half months.

4. One year and three months after operation, the patient was walking and well, with no signs of recurrence or metastasis. Radiographs showed that a block-vertebra had been created from the iliac grafts and the two cut vertebrae.

1. The pathological anatomy of total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb has been studied at operation in thirty-nine patients.

2. It has been found that the ligament, when ruptured distally (the most usual type) is often displaced so that the ulnar expansion of the dorsal aponeurosis–here referred to as the adductor aponeurosis–becomes interposed between the ruptured end of the ligament and the site of its attachment on the phalanx; the ligament gets folded over to a greater or lesser extent and the ruptured end sticks out beyond the proximal edge of the adductor aponeurosis. Such displacement of the ligament with interposition of the adductor aponeurosis was found in twenty-five of the thirty-nine cases. The ligament may also be displaced without the adductor aponeurosis being interposed (with a gap between the ruptured end and the site of itsattachment on the phalanx).

3. Variations in the pathological anatomy are illustrated by more detailed descriptions of nine cases. In one of these the adductor aponeurosis had got caught between the two surfaces of the joint, and in another the adductor aponeurosis was found ruptured as well as the ulnar collateral ligament.

4. On the basis of dissection studies on forty-two fresh post-mortem specimens, a rational explanation is given of the pathological anatomy.

5. The results of the present investigation on clinical and anatomical material provide a strong argument in favour of operative treatment for total rupture of the ulnar collateral ligament of the metacarpo-phalangeal joint of the thumb.

6. Aspects of diagnosis and operative technique are discussed.

A case of complete rupture of the axillary artery in a man aged eighty-seven is described. The injury occurred in connection with an antero-inferior dislocation of the shoulder. It is not known whether the rupture was caused by the dislocation itself or by the reduction. A successful suture of the artery was performed. A review of the literature is given, and earlier attempts to suture the artery in cases of this type are noted. The indications for this operation are discussed.

1. Five cases of pseudomalignant osseous tumour of soft tissue are reported.

2. Clinical and histological observations suggest that this lesion is a reactive condition initiated by an infection.

3. Tomography is helpful in demonstrating the characteristic peripheral ossification around non-ossified central regions of the lesion.

1. A twenty-six-year-old woman was paraplegic because of a benign giant-cell tumour which had destroyed the body of the twelfth thoracic vertebra completely and the bodies of the eleventh thoracic and first lumbar vertebrae partially. The tumour had expanded into both pleural cavities and displaced the aorta forward and to the left. The extent and topography of the tumour were evaluated before operation by angiography. The function of the spinal cord had not been improved significantly by laminectomy. It was therefore decided to attempt extirpation of the tumour by removing all remaining parts of the three vertebrae involved.

2. After the removal of the tumour, only the spinal cord with the thecal sac bridged the gap between the tenth thoracic and second lumbar vertebrae. The gap was bridged with struts of cortical bone from both tibiae and with two strong plates, all secured with steel wire. The metal was removed five months later because it had become loose. Gradual shortening and angulation of the spine then occurred, together with progressive resorption of the cortical grafts. Nevertheless, the operation restored the function of the spinal cord; the patient regained ability to walk and full control of the bladder.

Aims

To evaluate the perioperative complications associated with total en bloc spondylectomy (TES) in patients with spinal tumours, based on the extent and level of tumour resection.

Aims

There is an increased risk of dislocation of the hip after the resection of a periacetabular tumour and endoprosthetic reconstruction of the defect in the hemipelvis. The aim of this study was to determine the rate and timing of dislocation and to identify its risk factors.

The current indications for functional restoration of extension of the knee following quadriceps resection or loss require reappraisal. The contribution of pedicled and free functional muscle transfer is likely to be over-emphasised in many studies, with good functional outcomes predominantly reported only in the context of cases with residual quadriceps function. In cases with total quadriceps resection or loss, all forms of reconstruction perform poorly. Furthermore, in smaller resections with loss of two or fewer components of the quadriceps, minimal impairment of function occurs in the absence of functional reconstruction, suggesting that functional restoration may not be warranted. Thus there is a paradox in the current approach to quadriceps reconstruction, in that small resections are likely to be over-treated and large resections remain under-treated.

This review suggests a shift is required in the approach and rationale for reconstructing functional extension of the knee after quadriceps resection or loss. A classification based on current evidence is suggested that emphasises more clearly the indications and rationale for functional transfers.

Aims

Instability of the hip is the most common mode of failure after reconstruction with a proximal femoral arthroplasty (PFA) using an endoprosthesis after excision of a tumour. Small studies report improved stability with capsular repair of the hip and other techniques, but these have not been investigated in a large series of patients. The aim of this study was to evaluate variables associated with the patient and the operation that affect post-operative stability. We hypothesised an association between capsular repair and stability.

Objectives

Our objective was to predict the knee extension strength and post-operative function in quadriceps resection for soft-tissue sarcoma of the thigh.

Total en bloc spondylectomy (TES) is the total resection of a vertebra containing a tumour. Many authors have investigated patient-reported outcomes after routine spinal surgery and surgery for tumours in general. However, this is the first report of patient-reported outcomes, including health-related quality of life (HRQoL) and satisfaction, after en bloc vertebral resection for a spinal tumour.

Of the 54 patients who underwent TES for a primary tumour between 1993 and 2010, 19 died and four were lost to follow-up. In January 2012, a questionnaire was sent to the 31 surviving patients. This included the short form-36 to assess HRQoL and questions about the current condition of their disease, activities of daily living (ADL) and surgery. The response rate was high at 83.9% (26/31 patients). We found that most patients were satisfied and maintained good performance of their ADLs.

The mental health status and social roles of the HRQoL scores were nearly equivalent to those of healthy individuals, regardless of the time since surgery. There was significant impairment of physical health in the early post-operative years, but this usually returned to normal approximately three years after surgery.

There are few reports describing dislocation of the metacarpophalangeal joint of the thumb in children. This study describes the clinical features and outcome of 37 such dislocations and correlates the radiological pattern with the type of dislocation.

The mean age at injury was 7.3 years (3 to 13). A total of 33 children underwent closed reduction (11 under general anaesthesia). Four needed open reduction in two of which there was soft-tissue interposition. All cases obtained a good result. There was no infection, recurrent dislocation or significant stiffness.

So-called ‘simple complete’ dislocations that present with the classic radiological finding of the joint at 90° dorsal angulation may be ‘complex complete’ injuries and require open reduction.
