Minimally invasive dynamic hip screw for fixation of hip fractures

Michael Ho et al. Int Orthop. 2009 Apr.

Abstract

We compared a minimally invasive surgical technique to the conventional (open approach) surgical technique used in fixation of hip fractures with the dynamic hip screw (DHS) device. Using a case-control design (44 cases and 44 controls), we tested the null hypothesis that there is no difference between the two techniques in the following outcome measures: duration of surgery, time to mobilisation and weight bearing postoperatively, length of hospital stay, mean difference of pre- and postoperative haemoglobin levels, position of the lag screw of the DHS device in the femoral head, and the tip-apex distance. The minimally invasive DHS technique had significantly shorter duration of surgery and length of hospital stay. There was also less blood loss in the minimally invasive DHS technique. The minimally invasive DHS technique produces better outcome measures in the operating time, length of hospital stay, and blood loss compared to the conventional approach while maintaining equal fixation stability.

Ce travail a pour but de comparer les techniques de fixation de fractures de la hanche par voie mini-invasive ou par voie d’abord conventionnelle avec utilisation de matériel de type DHS. Nous avons pour cette étude regroupé les patients en deux groupes, 44 cas par voie mini-invasive et 44 cas contrôle. Nous avons voulu tester l’hypothèse suivante: existe-t-il une différence entre ces deux techniques, sur la durée d’intervention, de reprise de l’appui post-opératoire; de durée moyenne de séjour des pertes sanguines notamment et enfin, en ce qui concerne la position de la vis céphalique dans la tête fémorale et sa distance par rapport à l’interligne. La technique mini-invasive entraîne de façon significative un temps chirurgical diminué et une diminution de la durée moyenne de séjour. Ceci est également vrai pour les pertes sanguines. Cette technique est pour nous supérieure en ce qui concerne ces items si on la compare à l’abord de type conventionnel en sachant que les problèmes de stabilité du matériel sont identiques quelle que soit la technique utilisée.
