The aim of this study was to establish what happens to patients
in the long term after endoprosthetic replacement for a primary
malignant tumour of bone. We conducted a retrospective analysis of a prospectively maintained
database to identify all patients who had undergone an endoprosthetic
replacement more than 25 years ago and who were still alive. Their
outcomes were investigated with reference to their complications and
need for further surgery. A total of 230 patients were identified.
Their mean age at diagnosis was 20.7 years (five to 62). The most
common diagnosis was osteosarcoma (132). The most common site was
the distal femur (102). Aims

The scaphoid fracture is commonest in young men in the age group 15 to 29 years, who have the highest incidence of non-union, take the longest time to unite, lose more time from work, and spend the longest time as outpatients. A union rate of 95 per cent can be achieved using standard simple treatment. All but a few fractures are visible on the first radiograph, and failure of visualisation at this stage is not associated with a bad
Bisphosphonates reduce peri-prosthetic bone loss in the short term after total hip replacement but the mid- and longer term effects are not known. The aims of this randomised trial were to examine the effect of a single dose of 90 mg of pamidronate on the clinical and radiological

We performed ulnar nerve neurolysis and transposition during reconstructive operations on 20 consecutive patients (21 elbows) with neuropathy after the failure of primary treatment of elbow fractures. There were 11 men and nine women with a mean age of 48.3 years. Preoperatively, four elbows were in McGowan stage I, seven in stage II and ten in stage III and the mean Gabel and Amadio ulnar nerve score was 3.2. At a mean follow-up of 32.1 months (24 to 67) we performed comprehensive neurological, functional, electrophysiological and

Bariatric surgery has been advocated as a means
of reducing body mass index (BMI) and the risks associated with total
knee arthroplasty (TKA). However, this has not been proved clinically.
In order to determine the impact of bariatric surgery on the outcome
of TKA, we identified a cohort of 91 TKAs that were performed in
patients who had undergone bariatric surgery (bariatric cohort).
These were matched with two separate cohorts of patients who had not
undergone bariatric surgery. One was matched 1:1 with those with
a higher pre-bariatric BMI (high BMI group), and the other was matched
1:2 based on those with a lower pre-TKA BMI (low BMI group). In the bariatric group, the mean BMI before bariatric surgery
was 51.1 kg/m2 (37 to 72), which improved to 37.3 kg/m2 (24
to 59) at the time of TKA. Patients in the bariatric group had a
higher risk of, and worse survival free of, re-operation (hazard
ratio (HR) 2.6; 95% confidence interval (CI) 1.2 to 6.2; p = 0.02)
compared with the high BMI group. Furthermore, the bariatric group
had a higher risk of, and worse survival free of re-operation (HR
2.4; 95% CI 1.2 to 3.3; p = 0.2) and revision (HR 2.2; 95% CI 1.1
to 6.5; p = 0.04) compared with the low BMI group. While bariatric surgery reduced the BMI in our patients, more
analysis is needed before recommending bariatric surgery before
TKA in obese patients. Cite this article:
Until now, there has been no consensus as to whether stemmed
acetabular components are appropriate for use in patients undergoing
revision total hip arthroplasty (THA) who have major acetabular
defects or pelvic discontinuity. We wished to address this deficiency
in the literature. We carried out a retrospective study of 35 patients (six men
and 29 women) with a mean age of 68 years (37 to 87), with major
acetabular defects who underwent revision THA between 2000 and 2012.Aim
Patients and Methods
Mobile-bearing unicompartmental knee replacements
(UKRs) with a flat tibial plateau have not performed well in the
lateral compartment, owing to a high dislocation rate. This led
to the development of the Domed Lateral Oxford UKR (Domed OUKR)
with a biconcave bearing. The aim of this study was to assess the
survival and clinical outcomes of the Domed OUKR in a large patient
cohort in the medium term. We prospectively evaluated 265 consecutive knees with isolated
disease of the lateral compartment and a mean age at surgery of
64 years (32 to 90). At a mean follow-up of four years ( The Domed Lateral OUKR gives good clinical outcomes, low re-operation
and revision rates and a low dislocation rate in patients with isolated
lateral compartmental disease, in the hands of the designer surgeons. Cite this article:
This systematic review and meta-analysis was conducted to determine
the mid- to long-term clinical outcomes for a medial-pivot total
knee replacement (TKR) system. The objectives were to synthesise
available survivorship, Knee Society Scores (KSS), and reasons for
revision for this system. A systematic search was conducted of two online databases to
identify sources of survivorship, KSS, and reasons for revision.
Survivorship results were compared with values in the National Joint
Registry of England, Wales, and Northern Ireland (NJR).Objectives

We conducted a retrospective analysis of 94 children with fractures of the distal third of the radius, with or without ulnar fractures, treated by primary closed reduction and plaster. The overall failure rate of 29% was due mainly to irreducibility, inability to maintain reduction and eventual limitation of forearm rotation. Age, sex and severity of angulation were not significant, but the direction of angulation and the degree of translation at either the radial or the ulnar fracture sites were significant risk factors. Translation of the radius was the single most reliable predictor of
We evaluated the oncological and functional outcome
of 18 patients, whose malignant bone tumours were excised with the
assistance of navigation, and who were followed up for more than
three years. There were 11 men and seven women, with a mean age
of 31.8 years (10 to 57). There were ten operations on the pelvic
ring and eight joint-preserving limb salvage procedures. The resection
margins were free of tumour in all specimens. The tumours, which
were stage IIB in all patients, included osteosarcoma, high-grade
chondrosarcoma, Ewing’s sarcoma, malignant fibrous histiocytoma
of bone, and adamantinoma. The overall three-year survival rate
of the 18 patients was 88.9% (95% confidence interval (CI) 75.4
to 100). The three-year survival rate of the patients with pelvic malignancy
was 80.0% (95% CI 55.3 to 100), and of the patients with metaphyseal
malignancy was 100%. The event-free survival was 66.7% (95% CI 44.9
to 88.5). Local recurrence occurred in two patients, both of whom
had a pelvic malignancy. The mean Musculoskeletal Tumor Society
functional score was 26.9 points at a mean follow-up of 48.2 months
(22 to 79). We suggest that navigation can be helpful during surgery for
musculoskeletal tumours; it can maximise the accuracy of resection
and minimise the unnecessary sacrifice of normal tissue by providing
precise intra-operative three-dimensional radiological information.
A giant cell tumour is a primary lesion of bone of intermediate severity. Its histogenesis is unclear. In a few cases pulmonary metastases have been described. Multiple skeletal metastases in the absence of sarcomatous change have been observed. We present a case report of a 25-year-old woman with a recurrent giant cell tumour of the distal fibula. After a second recurrence and six years after the initial diagnosis, she rapidly developed multiple bony metastases. The
