Only a few cases of palmar carpal subluxation associated with an ulnovolar fragment from the distal radius have been reported previously. We report a case which was treated operatively six months after the
A case of total dislocation of the ilium after disruption through the tri-radiate cartilage in a girl of thirteen years is described. No previous description of this

Two protocols for the operative technique and care of the pin-site with external fixation were compared prospectively. There was a total of 120 patients with 46 in group A and 74 in group B. Infection was defined as an episode of pain or inflammation at a pin site, accompanied by a discharge which was either positive on bacterial culture or responded to a course of antibiotics. Patients in group B had a lower proportion of infected pin sites (p = 0.003) and the time to the first episode of infection was longer (p <
0.001). The risk of pin-site infection is lower if attention is paid to avoiding thermal
An 18-year-old man who presented with weakness in his lower limbs, had an upper motor neurone lesion at the D12-L1 level. At laminectomy two stone-like objects were found which proved to be bundles of tiny pieces of wood. They are thought to have entered the cord through an abdominal penetrating
We present a case of L2/3 interspinous bursitis treated with extraspinal injections. No previous investigations have used fluoroscopically guided spinal injections to confirm the clinical relevance of the MRI features of this type of bursae. Autopsy studies have revealed an increased incidence of interspinous lumbar bursal cavities with advancing age. Afflicted patients present with localised, midline lower lumbar pain exacerbated by extension. In young athletes these symptoms can mimic spondylolysis. MRI is useful in detecting soft-tissue
1. The clinical aspects of fifty-six patients with rupture of the tendo calcaneus are discussed, and the mechanism of
The case is reported of a fracture-dislocation of the shoulder, treated by an operation based upon a principle advanced by Moore in 1948. An excellent radiological and functional result was observed five and a half years after the
1. Three cases of traumatic thrombosis of the iliac arteries and one case of a false aneurysm of the internal iliac artery following closed

Recently, high failure rates of metal-on-metal (MOM) hip implants have raised concerns of cobalt toxicity. Adverse reactions occur to cobalt nanoparticles (CoNPs) and cobalt ions (Co2+) during wear of MOM hip implants, but the toxic mechanism is not clear. To evaluate the protective effect of zinc ions (Zn2+), Balb/3T3 mouse fibroblast cells were pretreated with 50 μM Zn2+ for four hours. The cells were then exposed to different concentrations of CoNPs and Co2+ for four hours, 24 hours and 48 hours. The cell viabilities, reactive oxygen species (ROS) levels, and inflammatory cytokines were measured.Objectives

and total knee arthroplasty (TKA) patients prior to (1263) and following
(1422) the introduction of an infection detection protocol. The
protocol used conservative thresholds for C-reactive protein to
direct the medical attendant to aspirate the joint. The protocol
incorporated a clear set of laboratory and clinical criteria that
allowed a patient to be discharged home if all were met. Patients were
included if they presented to our emergency department within 120
days post-operatively with concerns for swelling, pain or infection
and were excluded if they had an unambiguous infection or if their
chief complaint was non-orthopaedic in nature.Aims
Patients and Methods
The anatomy of the first metatarso-phalangealjoint and of dorsal dislocation of the phalanx are described. As with similar lesions in the hand, closed reduction is impossible because of interposition of the volar plate. Open reduction is essential and should be performed as soon as possible after the
The operation has the advantage of simplicity, and it avoids the slight danger of secondary cicatricial contracture of the nerve when it is transplanted anteriorly and implanted in muscle. There is a slight hazard from external
A classification of Smith's fractures into three types is proposed. It is suggested that the majority of these fractures are caused by a pronation
