Isolated capitellar fractures are rare, accounting for only 1 per cent of all elbow fractures (Bryan and Morrey, The Elbow and its Disorders, 1985). Many different fixation methods have been described but no series has compared these treatment modalities because of the rarity of these fractures. This paper compares the outcome of two types of fixation of(More)
BACKGROUND Jones fractures of the fifth metatarsal can be stabilized using intramedullary screw fixation techniques. A range of screw diameters from 4.5 mm to 6.5 mm can be used, but the optimal screw for this procedure has yet to be defined. In clinical practice, we have observed that failure is more likely when smaller diameter screws are used. METHODS(More)
The management of the patella in total knee arthroplasty still causes controversy. Whether or not to resurface the patella in primary total knee arthroplasty remains unclear. In this study we examined 220 consecutive total knee replacements, by a single surgeon, where the patella was routinely resurfaced using the inset technique. All patellae were suitable(More)
Children who toe-walk can pose a diagnostic problem. The differential diagnosis includes mild spastic diplegia and idiopathic toe-walking. Clinical differentiation between these two patient groups can be particularly difficult, and there are no objective diagnostic tests to assist the clinician. We assessed 50 children who toe-walk to define the kinematic(More)
Human bites of the hand cause small wounds that are often incorrectly treated as "minor' injuries. We reviewed the management and outcome of patients with human bite or "punch' injuries of the hand. Significant morbidity resulted from late presentation and inadequate initial management. We propose a treatment protocol, in which all patients are immediately(More)
Fractures of the proximal humerus account for 4–5% of all fractures with 80% requiring no surgical treatment. However, the management of the other 20% remains controversial. This study followed a series of 27 patients who had proximal humeral internal locking system (PHILOS) plate fixation of their proximal humeral fractures. All patients were followed up(More)
With a few exceptions, today’s mobile robots, however complex, are not truly autonomous. At some time, they all require humans to supply them with energy and/or information; most also require other forms of assistance. In complete contrast, even the simplest animals are totally self-sufficient. We describe a current project1 which aims to construct(More)
One of the key aspects of most living organisms is their ability to detect and exploit natural sources of energy within their environment. We are currently developing a robotic predator system that will attempt to sustain itself by hunting and catching slugs on agricultural land. A microbial fuel cell will be used to convert the slug bio-mass to electricity(More)
