We performed a randomised controlled study to compare heparin with the A-V Impulse System in the prevention of deep-vein thrombosis (DVT) in 132 consecutive patients undergoing total hip replacement. After the operation, all patients had compression stockings, 65 were treated with calcium heparin and 67 with the intermittent plantar pump. DVT was diagnosed by Doppler ultrasound and thermography, followed by phlebography. There were 23 cases of DVT (35.4%) in the heparin group, with 16 m& jor and seven minor thromboses. In the impulse pump group there were nine cases (13.4%) with three ma jor and six minor thromboses. The differences for all thromboses and for major thromboses were both significant at p < 0.005. In the heparin group there was one fatal pulmonary embolism and nine patients (13.8%) had excessive bleeding or wound haematomas, as against none in the impulse pump group.
We reviewed the outcome of 33 patients (45 feet) treated by scarf osteotomy for hallux valgus deformity with an intermetatarsal (IM) angle equal to or greater than 16°. The average follow-up was 26 months. The hallux valgus angle improved by an average of 21.1°from a preoperative mean value of 32.1°. The IM 1-2 angle improved an average of 9.9°from a preoperative mean value of 18.3°. American Orthopedic Foot and Ankle Society (AOFAS) score changed from a preoperative average of 35.7 points to 89.8 at follow-up. Our midterm results indicate that the scarf osteotomy provides an effective method for the treatment of severe bunion deformity.Résumé Nous avons examiné le résultat de 33 malades (45 pieds) traité par ostéotomie scarf pour hallux valgus avec un angle intermétatarsien égal ou supérieur à 16°. La suivi moyen était 26 mois. L'angle de l'hallux valgus a été amélioré avec une moyenne de 21.1°après l'opération à partir d'une valeur préopératoire de 32.1°. L'angle intermetatarsienne 1-2 avait une moyenne de 9.90 à partir d'une d'une valeur préopératoire de 18.3°. Le score AOFAS moyen a progressé de 35.7 points à 89.8 points au recul. Nos résultats intermédiaires indiquent que les ostéotomies scarf fournissent une méthode efficace pour le traitement de l'hallux valgus sévère.
We reviewed 42 patients (mean age 37.7±14.2 years) with closed fracture dislocations of Lisfranc's joint treated with percutaneous screw fixation. Mean follow-up was 58.4±17.3 months. The aim was to compare dislocations in which a perfect anatomical reduction had been reached with dislocations in which reduction was only near anatomical. The mean American Orthopaedic Foot and Ankle Society score for all patients was 81.0±13.5. There were no significant differences in outcome scores between patients with perfect anatomical reduction and patients with near anatomical reduction. However, patients with combined fracture dislocations obtained statistically better scores than patients with pure dislocations. Résumé Nous avons revu 42 malades (âge moyen 37.7±14.2 années) ayant présenté une fracture-luxation du Lisfranc traitée par vissage percutané. Le suivi moyen de était 58.4±17.3 mois. Le but était d'étudier les différences entre les luxations réduites anatomiquement et celles qui ne l'étaient pas parfaitement. Le score AOFAS moyen pour tous les malades était 81.0±13.5. Il n'y avait pas de différences notables dans les scores entre malades avec parfaite réduction anatomique et malades avec réduction anatomique approximative. Les patients avec fracture-luxation ont cependant obtenu statistiquement de meilleurs scores que les patients avec luxation pure.
