Introduction: Intra-articular injection of steroid to the hip prior to joint arthroplasty has been suggested in some studies to carry a risk of infection up to 30% and subsequent revision surgery required in up to 12.5%.

Methods: We undertook a review of all intra-articular hip injections performed at the Queen Alexandra Hospital, Portsmouth and the Royal Haslar Hospital, Ports-mouth between January 2000 and April 2006. Hospital notes including operation notes, anaesthetic preoperative assessments and clinic letters were used to collect the following data. Name, age, sex, and premorbid conditions in particular diabetes, medication, date of injection, substance injected, date of arthroplasty and post operative complications.

Results: 370 intra-articular hip injections were performed of which 55 subsequently had total hip arthroplasty. 1 required washout post operatively but components remained and to date have not required revision. 1 required excision arthroplasty to eradicate deep infection and is still awaiting revision arthroplasty. This shows an infection risk of 3.6% and revision rate of 1.8%.

Discussion: Our review does not show a high rate of infection following intra-articular injection. We conclude that the therapeutic and diagnostic benefits of intra-articular injection may be considered prior to total joint arthroplasty without the increased risk of subsequent infection

25 cases of closed fractures around the distal femoral growth plate were analysed prospectively over a one-year period. There were 22 males and 3 females. Mean age was 16 years (range 7 to 22).

According to the classification of Salter and Harris there were 6 cases (24%) of type 1 fracture, 12 (48%) type 2 fractures, 3 (12%) type 3, and 4 (16%) type 4. Mechanism of injury was football in 13 (59%), simple fall in 4 (18%), crush in 2 (9%), RTA in 2 (9%), and fall from height in 1 (5%); in 3, the mechanism was not recorded. The average time from injury to hospital admission was 5 days (range 0 to 17 days).

Management was conservative in 4 and operative in 21. The medial parapatellar approach was used in 16. Post-surgically plaster cylinders were used for a mean of 3 weeks (range 0 to 6 weeks). No patient received physiotherapy.

In the operative cases, sepsis was observed in 1 case (5%). This was a crash injury with a skin ulcer that became septic postoperatively and later required knee fusion.

Of the remaining 20 operative cases, 17 cases were reviewed, 4 to one year, 9 to six months, and 4 to three months. There were no cases of deformity, nor wound complications. Those reviewed at one year had an excellent range of movement averaging 0 to 117 degrees (range 0–100 to 0–140). At six months the average range of movement was 1–98 degrees (range 5–70 to 0–140) and at three months 2–62 degrees (range 10–50 to 0–95).

In conclusion, we believe that these difficult fractures should usually be managed operatively where expertise allows. Preliminary results suggest that the medial parapatellar approach provides excellent access but may inhibit initial rehabilitation.

A prospective study was undertaken of wound healing in HIV positive patients undergoing orthopaedic implant surgery. 175 implant operations were assessed. 40 operations (23%) were in HIV positive individuals. Wounds were scored using the Asepsis scoring system.

Closed fractures in HIV positive patients had 1 (3. 5%) major infection. No correlation was seen between CD4 count and risk of wound infection.

With regards to early wound sepsis, implant surgery can be undertaken safely in HIV positive individuals with closed injuries regardless of CD4 count. The risk of wound sepsis rises dramatically in implant surgery for HIV positive patients with open fractures.
