Introduction. Direct lateral approaches to the hip require detachment and repair of the anterior part of the gluteus medius and minimus tendon attachments. Limping may occur postoperatively due to nerve injury or failure of muscle re-attachment. The aim of this study was to assess the integrity of abductor muscle repairs using a braided wire suture marker. Methods. Total hip arthroplasties were inserted using a modified Freeman approach. After repair of the abductor tendons using a 1 PDS suture with interlocking Kessler stitches, a 3–0 braided wire suture marker was stitched into the lower end of the flap. The suture was easily visible on postoperative radiographs and its movement could be measured. Patients were assessed using radiographs and Oxford hip scores collected prospectively. Results. 56 joint replacements were performed in 51 patients with no major surgical complications. Mean age was 65 yr and 80% (n=41) were female. It proved possible to reproducibly classify repairs based on radiographic measurements as: no wire movement (43%); repair stretched, moving cephalad a short distance (46%); repair detached, moving cephalad a significant distance (11%). Risk of failure of the repair had no relationship with age, preoperative Oxford hip score, or postoperative Oxford hip score. The mean Oxford hip score drop in the no movement group was 36%, the stretched group 37%, and the detached group 33%. These differences were not significant. Discussion/Conclusion. The wire marker proved to be a revealing method of auditing abductor repair following hip arthroplasty. No difference was demonstrated in outcome in relation to wire movement, therefore this study did not show any advantage from a careful repair technique. Due to the small number of failed repairs there may be a type II error. This method may also be useful in assessing the integrity of other large tendon repairs, such as quadriceps tendons splits in total knee replacements

We report the functional and socioeconomic long-term outcome of patients with pelvic ring injuries.

We identified 109 patients treated at a Level I trauma centre between 1973 and 1990 with multiple blunt orthopaedic injuries including an injury to the pelvic ring, with an Injury Severity Score (ISS) of ≥ 16. These patients were invited for clinical review at a minimum of ten years after the initial injury, at which point functional results, general health scores and socioeconomic factors were assessed.

In all 33 isolated anterior (group A), 33 isolated posterior (group P) and 43 combined anterior/posterior pelvic ring injuries (group A/P) were included. The mean age of the patients at injury was 28.8 years (5 to 55) and the mean ISS was 22.7 (16 to 44).

At review the mean Short-Form 12 physical component score for the A/P group was 38.71 (22.12 to 56.56) and the mean Hannover Score for Polytrauma Outcome subjective score was 67.27 (12.48 to 147.42), being significantly worse compared with the other two groups (p = 0.004 and p = 0.024, respectively). A total of 42 patients (39%) had a limp and 12 (11%) required crutches. Car or public transport usage was restricted in 16 patients (15%). Overall patients in groups P and A/P had a worse outcome. The long-term outcome of patients with posterior or combined anterior/posterior pelvic ring injuries is poorer than of those with an isolated anterior injury.
