OBJECTIVE To compare the relative risks of serious gastrointestinal complications reported with individual non-steroidal anti-inflammatory drugs. DESIGN Systematic review of controlled epidemiological studies that found a relation between use of the drugs and admission to hospital for haemorrhage or perforation. SETTING Hospital and community based… (More)
A "six strand" method of tendon repair has been used to treat 36 fingers with flexor tendon lacerations. Following surgery, active mobilisation in a protective splint was begun immediately. 63% of lacerations were in zone 2 and 27% in zone 1. 69% and 100% respectively achieved an excellent or good result using Buck-Gramcko's assessment method. 81% of all… (More)
The mechanical factors in tendon repair have been studied and physical principles applied to this unsolved problem. A new technique of tendon repair has been derived and tested in the laboratory. Compared to several well known techniques it has been shown to have three times the tensile strength and to allow one tenth the gap to form between the tendon ends… (More)
The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored… (More)
Contracture of the proximal interphalangeal joint after surgery to excise Dupuytren's disease, despite release of the contributory structures within the finger, can be caused by flexor digitorum superficialis (FDS) contracture. We describe five cases where FDS contracture was released by intramuscular tenotomy in the distal forearm. Standard postoperative… (More)
In a retrospective study, patients with suspected scaphoid fracture had an average of three sets of scaphoid radiographs prior to scintigraphy. Scans were performed an average of 3 months after injury and many were inconclusive because of disuse changes. A prospective analysis of early scintigraphy in 35 cases over 18 months was carried out. Scans were… (More)
We report a series of scaphoid fractures fixed with titanium alloy Herbert screws in which postoperative Magnetic Resonance Imaging (MRI) was used to assess the marrow signal in the proximal pole of the scaphoid and thus detect the presence of avascular necrosis. The artefact produced by the titanium alloy Herbert screw did not preclude this assessment.
Metal implants produce susceptibility artefacts in magnetic resonance imaging. We have explored the effects of scaphoid screw characteristics and orientation on MR susceptibility artefact. Titanium alloy, smallness and longitudinal alignment with the z-axis of the main magnetic field reduce the size of the susceptibility artefact.
A case of fracture-separation of the distal phalanx epiphysis, with complete detachment from soft tissue, is reported and discussed.
Active and passive muscle tension is discussed in relation to finger flexor and extensor tendons. Minimising active tension required to produce finger movement is seen as an important part of post-operative finger mobilisation following flexor tendon repair in which active movement is used. It is argued that "minimal active tension" in the flexors is equal… (More)
