Should full threaded compression screws be used in adult XXXX ?

@entity1 @entity2249 @entity174 @entity130
INTRODUCTION: Operative treatment consisting of @entity174 reduction and fixation, or arthroplasty to permit early @entity1 mobilization, continues to be the treatment of choice for most @entity2249 . Options for internal fixation have included a variety of implants; however most recent reports and textbooks cite parallel multiple cancellous screws as the surgical technique of choice. METHODS: The study was prospective, randomized and IRB approved. Inclusion criteria included skeletal maturity, closed @entity2249 without concomitant @entity174 or @entity130 with complete charts and adequate radiographs obtained from the initial injury till the last follow-up. Forty-four @entity1 were enrolled in this study during one-year period at two university centers. 22 were randomized to be treated with full threaded, cannulated compression screws (Acutrak 6/7, ACUMED) (Group 1) and the other 22 with 16mm partial threaded, 6.5mm or 7.3mm cannulated screws (SYNTHES) (Group 2). Three or four screws were used in both groups according to @entity174 type and surgeon's preference. Data evaluated included surgical time, fluoroscopy time, @entity174 type, radiological outcome, complications and functional status using the Harris Hip Score. RESULTS: Both groups were comparable in terms of age and gender. There was not a significant difference in terms of surgical time, follow-up period, @entity174 type, or fluoroscopy time. There were eight complications in Group 1 and two in Group 2 (P=0.049) Time to union was significantly longer in Group 1 (P=0.001). However, Hip Scores were not significantly different in both groups (P=0.20). CONCLUSION: When compared with full threaded compression screws, partial-threaded cannulated screws provides a shorter union time and less complication rate while providing equivalent functional results in adult @entity2249 .
