1/81. The effect of hallux valgus correction on chronic plantar ulceration. A case report. Plantar pressure-measurement technology may provide the clinician with valuable objective information for monitoring the effects of therapeutic intervention on the foot. The use of this technology is described in the preoperative and postoperative assessment of a patient undergoing hallux valgus surgery for the treatment of a chronic neuropathic skin ulcer over the medioplantar aspect of her first metatarsophalangeal joint.

2/81. Proximal articular set angle. Radiographic versus intraoperative measurement. The authors conducted a study to investigate the variability of measurement of the proximal articular set angle. The proximal articular set angle as measured radiographically was compared with the proximal articular set angle as measured intraoperatively. Three groups of evaluators--attending physicians, residents, and third-year podiatric medical students--measured the proximal articular set angle radiographically. The mean measurement, standard deviation, and difference between the mean radiographic measurement and the intraoperative measurement were determined for each group. The authors concluded that the only accurate proximal articular set angle measurement is the intraoperative measurement. ( info) |
3/81. The musculoskeletal manifestations of Werner's syndrome. Werner's syndrome is a rare condition usually presenting as premature ageing in adults. Over a period of 30 years we have followed two siblings with extensive musculoskeletal manifestations including a soft-tissue tumour, insufficiency fractures, nonunion and tendonitis, with associated problems of management. The literature is reviewed. ( info) |
4/81. A phylogenetic analysis elucidating a case of patient-to-patient transmission of hepatitis c virus during surgery. A phylogenetic hepatitis c virus (HCV) assay based on the core-Envelope 1 (C-E1) region was developed and used to elucidate a case of a patient-to-patient transmission. The index patient showed clinical symptoms of hepatitis seven weeks after surgery for hallux valgus under general anaesthesia. She progressed to a chronic persistent infection as indicated by positive HCV PCR results two years after surgery. Before her operation, a patient with HCV antibodies and positive HCV PCR had undergone surgery in the same room. There were two possibilities whereby the index patient could have been infected with hepatitis c, either through her work as a nurse or by transmission during surgery. By sequencing the 5' non-coding region PCR product, we found that both patients were infected with genotype 1a. Phylogenetic analysis with the variable C-E1 region suggested that the two patients clustered together with a bootstrap 100% in a tree with 75 sequence references. We further performed a phylogenetic analysis in this region with the genotype 1a reference sequences and an additional 25 genotype 1a sequences consecutively collected from Danish patients with HCV. The two patients still clustered together, supported by a high bootstrap 1000 value of 999. Homology analyses combined with the epidemiological findings indicate that the patient operated on in the same room before the index case was the most likely source of transmission. The mode of transmission could not be conclusively established, but a reusable part of the anaesthetic respiratory circuit is a possibility and a well known risk. ( info) |
5/81. An unusual exostosis presenting as a bunion deformity. A large exostosis was the source of a bunion deformity in a 60-year-old woman. Its unusual clinical and radiographic features were suggestive of a bizarre parosteal osteochondromatous proliferation. However, histologic features were most consistent with a benign osteocartilaginous exostosis. ( info) |
6/81. Microscopic metallic wear and tissue response in failed titanium hallux metatarsophalangeal implants: two cases. The membranes present at the implant-bone interface were retrieved from two patients with titanium single stem hallux implants that had failed. Both patients had pain and valgus deformity of the hallux, and radiographs showed a radiolucent shadow around the implant stem, with thinning of the dorsal cortex of the proximal phalanx in one patient. After removal of the implants, arthrodesis of the first metatarsophalangeal (MP) joint was performed. Histologic analysis of the membrane tissue at the implant-bone interface showed a synovial-like appearance. There was a fibrous tissue stroma adjacent to the bone surface, with multiple regions of scalloping covered by mononuclear cells. Fine metallic debris was seen throughout the fibrous tissue. Multinucleated foreign body giant cells were sparsely observed associated with fine particulate metallic wear debris similar to observations from failed total hip arthroplasties. The histologic appearance is evidence that foreign-body granulomatous infiltration associated with metallic wear debris may be a causative factor of peri-implant osteolysis leading to aseptic loosening and failure of titanium single stem hallux implants.

| It is difficult to surgically treat a hallux valgus deformity with significant metatarsus adductus, because the space between the first and second metatarsals is too narrow to correct the metatarsus primus varus with a first metatarsal osteotomy. A 55-year-old woman had severe hallux valgus with significant adduction of the second and third metatarsals. A distal soft tissue procedure and a proximal crescent-shaped osteotomy of the first metatarsal combined with corrective osteotomies of the second and third metatarsals were done. The patient's symptoms disappeared, and hallux valgus and adduction of the second and third metatarsals were corrected. To the authors' knowledge, there is no previous description of surgical treatment including correction of metatarsus adductus and hallux valgus for adult hallux valgus with metatarsus adductus.

| Metatarsophalangealjoint injuries of the great toe are receiving increasing attention in athletes. Significant disability and long-term morbidity can result from these focal injuries. The entity known as turf-toe is widely recognized. rupture of the medial collateral ligament of the first metatarsophalangeal joint is less common. A case of traumatic rupture of the medial collateral ligament in the great toe of a soccer player, which progressed to hallux valgus deformity, is presented. ( info) |
9/81. An unusual case of a postoperative bone cyst. We describe an unusual case of a postoperative bone cyst resulting from a retained fragment of surgical glove. We highlight some of the problems associated with gloves and suggest ways of safeguarding against similar complications. ( info) |
10/81. Extensor hallucis longus tendon rupture repair using a fascia lata allograft. The authors present a case of a traumatic extensor hallucis longus tendon rupture sustained 2 days after hallux valgus and hammer toe correction. The ruptured tendon, separated by a 6-cm defect, was repaired using a fascia lata allograft. This case demonstrates a serious complication of a commonly performed procedure and a salvage technique useful for dealing with large tendon defects. ( info) |
