We report a case of anterior compartment syndrome in the ipsilateral leg after a revision total hip arthroplasty. Possible causes include post-ischaemic swelling after occlusion of the vessels during prolonged surgery and vigorous repetitive stretching of the muscles of the anterior compartment from the intraoperative use of electrical calf stimulators.(More)
This retrospective study compares three of surgical treatments for osteoarthritis of the trapeziometacarpal joint of the thumb. We assessed the outcomes of a total of 83 operations at a follow-up of between 1 and 5 years. The types of treatment were, fusion of the carpometacarpal joint (36 operations), excision of the trapezium with or without a sling(More)
Thirty-six patients were reviewed by questionnaire after operative treatment for trigger finger or thumb. Multiple digital involvement occurred in just under one third of the patients in this series and the index and little fingers were relatively rarely involved. Five patients had close relatives affected by the same condition. 17% of patients in this(More)
We report the clinical and radiologic outcome of 109 Chamley low-friction arthroplasties implanted with Boneloc bone-cement (Biomet, Bridgend, South Wales, UK) into 104 patients. The mean follow-up was 30 months (range, 2-48 months). There were 72 women (mean age, 71 years) and 32 men (mean age, 72). Cartridge-packed cement was used in 37 cases and(More)
Vectorization algorithms described in the literature assume that the drawings being vectorized are either binary images or have a clear white background. Sketches of artistic objects however also contain shadows which help the artist to portray intent, particularly in potentially ambiguous sketches. Such sketches are difficult to binarise since the shading(More)
In this paper we introduce a path extraction algorithm for multi-stroke scribbled paths by making use of path-centred concentric sampling circles. Circle and line geometry is then exploited to efficiently obtain piece-wise linear models of the multi-stroke segments in the drawing. Parzen window estimation is used to obtain the probability distribution of(More)
The cytogenetics of cell cultures derived from Dupuytren's tissue, adjacent palmar fascia and palmar skin from patients undergoing fasciectomy have been examined and the results compared to cell cultures established from palmar fascia, flexor retinaculum and palmar skin of patients undergoing carpal tunnel decompression. Chromosomal abnormalities were(More)
The results of posterolateral screw fixation using the Buck technique performed on 24 patients with painful isthmic spondylolysis and up to grade I spondylolisthesis in the lumbar spine are reported. The average age at operation was 29 years and average follow-up was 5 years with a range of 13 months to 12 years. Operations were performed for persistent(More)
Artistic cues help designers to communicate design intent in sketches. In this paper, we show how these artistic cues may be used to obtain a line labelling interpretation of freehand sketches, using a cue-based genetic algorithm to obtain a labelling solution that matches design intent. In the paper, we show how this can be achieved from off-line or paper(More)
