Acetabular revision surgery remains a technically demanding procedure with higher failure rates than primary total hip arthroplasty (THA). An acetabular component with three dimensional porous titanium and anatomic screw holes (Figure 1) was designed to allow the cup to be positioned anatomically and provide reliable fixation. A prospective multicenter study of 193 cases (190 patients) was conducted to assess the midterm clinical outcomes of the revision titanium acetabular shell. Radiographs, demographics, Harris Hip Score (HHS), and Short Form 36 (SF-36) were collected preoperatively, at 6 weeks, 3 months, and annually thereafter to 5 years. The mean duration of follow-up was 3.36 years. The Paprosky classification was assessed intraoperatively. Short Form 6D (SF-6D) utility values were obtained by transforming SF-36 scores through the Brazier method and were analyzed for effect size.Introduction
Methods
The purpose of the study was to investigate the incidence of surgical site infection following elective paediatric orthopaedic surgery. A pro forma adopted from a pilot study was filled out preoperatively for each elective operation performed during the study period. Each patient was then followed up for six weeks postoperatively to record any SSI that developed. Data collected included patient demographics, type of operation, grade of Surgeon, type of procedure, wound length, skin preparations, use of tourniquet, any antibiotic prophylaxis and length of operation. This study collated data on 334 operations with 410 procedural sites over a six month period. Infection were recorded in 19 sites equivalent to a SSI rate of 4.63%. None of the patients developed long-term complications. The mean age of the participants in the study was 11 years (range 0.5 to 17 years), 57% were males and 43% were females. The infection were detected between 1 and 38 days after surgery. The outcome was not compromised in any of the patients as none of them required long-term treatment. Statistical analysis was undertaken. The study proves that the surgical site infection after elective paediatric orthopaedic surgery is low and serve as a bases for consenting patients for surgery.
