We compared the postoperative wound discharge rates and 3 months clinical results of three types of wound closure and dressing – 2-octylcyanoacrylate with Opstie (G+O), 2-octylcyanoacrylate with Tegaderm (G+T), and Opsite without 2-octylcyanoacrylate (O) in patients having primary total hip arthroplasty.

We randomised 141 patients scheduled for primary total hip arthroplasty into 3 arms of this study- G+O, G+T, or O. The extent of wound discharge was recorded on a diagrammatic representation of the dressing in situ on paper and graded each day. Dressings were left in-situ provided the extent of wound discharge allowed for this. The patient was clinically reviewed at 3 months to assess their scar length, cosmesis, scar discomfort, and evidence of superficial or deep wound sepsis.

A greater number of patients dressings remained dry on day 1 postoperatively in the two groups with 2-octylcyanoacrylate compared to the no glue group p=0.001. G+T group had a significantly lower proportion of patients with increased leakage of wounds on 2^nd postoperative day p=0.044. At 3 months review, there was no statistical difference in the Hollander score or scar discomfort.

In patients who have had primary total hip arthroplasty, usage of 2-octylcyanoacrylate for wound closure along with Tegaderm dressing reduces wound discharge. The same effect is not noted in glue with Opsite group. Whilst dressing changes required in the non-glue group compared from the two glue groups did not reach statistical significance, this may have clinical relevance for patients and nursing staff. No effect on postoperative length of stay, or wound complications was noted.

Introduction: The open treatment of hip impingement is now a well-recognised technique with numerous publications about pathogenesis and surgical technique. There are very few publications of very small series discussing surgical results.

We present the results of 148 hips at a mean follow-up of 20 months (range 4 – 55).

Methods: This is a two surgeon series of sequential patients including the early learning curve. Patients were treated for impingement through a Ganz trochanteric osteotomy and open surgical hip dislocation. Patient data, operative findings and methods, complication and clinical follow up were recorded as a prospective audit and include Oxford and McCarthy Non Arthritic Hip scores.

Results: The patient demographics are as follows:

141 patients, 148 hips.

We have had the following complications: 4 trochanteric non unions requiring revision fixation, 2 deep vein thrombosis, 2 haematomas, 1 superficial infection, no deep Infections.

Life table survival curve with revision to arthroplasty defined as failure.

Discussion: The early to midterm results of this innovative procedure are encouraging even when including the decision making and surgical technique learning curves. We will present the hip scores and discuss the failures in detail to warn others embarking on this surgery which cases are more likely to lead to unsatisfactory outcomes.
