In a retrospective study we compare the functional and radiographical results of 2 groups of patients with unstable distal radial fractures treated with external fixation. In Group 1, 20 patients with 21 fractures were treated with external fixation for 3 weeks followed by a cast for 2 weeks. In Group 2, 16 patients were treated with external fixation for 5 weeks. The functional outcome was good in both treatment groups with no significant difference between the results in the two groups. Radiologically, Group I had less radial shortening than Group II, but there was no difference in the dergee of dorsal angulation.Résumé Dans une étude rétrospective nous avons comparé les résultats fonctionnels et radiographiques de deux groupes de traitements de fractures distales du radius. Dans le premier groupe, 20 patients avec 21 fractures ont été traités avec fixation externe pendant 3 semaines suivies d'immobilisation platrée pendant 2 semaines. Dans le deuxième groupe, 16 patients ont été traités avec fixation externe pendant 5 semaines seulement. Le résultat fonctionnel a été bon dans tous les cas, sans différence significative entre les deux groupes. Du point de vue radiologique on a constaté dans le premier groupe une longueur radiale plus grande que dans le groupe traité pendant 5 semaines, mais pas de diffèrence dans l'angulation dorsale.
To evaluate the midterm performance of Boneloc cemented primary Exeter hip arthroplasty we examined the first 100 hips in 93 patients, who were alive at a median 56.6 (50–62) months after the operation. During the follow-up period 2 femoral stems and 2 acetabular cups were revised because of aseptic loosening from 3–5 years after the operation. A third acetabular cup was revised at the same time as a loose femoral stem, but was not found loose. The 5-year survival of both the stem and the cup was 98 per cent and for the surviving 98 hips the average Harris Hip Score was 87.6 (43–100) and the average pain score was 42.2 (10–44). Eighty nine per cent of patients were very satisfied or satisfied with their hip prosthesis and the patients’ own evaluations correlated well with the Harris Hip Scores. Follow-up radiographs revealed definite loosening of 3 stems and 2 cups, probably loosening of one stem and 2 cups, and possibly loosening of 2 stems and one cup. The Exeter stem subsided significantly within the cement mantle by median 3.3 (0–19) mm. In a subgroup of patients subsidence diminished significantly from the first 28 months compared to the last 31 months. Subsidence at the cement bone interface was only seen in 4 hips, where cement fractures had developed. Poor quality cementation, and valgus position of the femoral stem, significantly increased the risk of aseptic loosening, as did osteolysis and cement fracture. Poor cementing technique and continuous radiolucent lines at follow-up radiographs were positively correlated with acetabular cup loosening. The rather good midterm results with the Exeter femoral stem can probably be ascribed to the collarless, polished, double tapered stem design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
