Laminar airflow systems are universal in current orthopaedic operating theatres and are assumed to be associated with a lower risk of contamination of the surgical wound and subsequent early infection. Evidence to support their use is limited and sometimes conflicting. We investigated whether there were any differences in infection rates (deep and superficial) between knee and hip arthroplasty cases performed in non-laminar and laminar flow theatres at 10 year follow-up.

Between 2002 and 2006, 318 patients underwent knee and hip arthroplasty in a non-laminar flow theatre. Prospectively collected local arthroplasty audit data was collected including superficial and deep infection, revision for infection and functional outcomes. A cohort of patients from the same time period, who underwent knee and hip arthroplasty in a laminar flow theatre, were matched for age, sex, body mass index (BMI), operative approach, implant and experience of surgeon.

Superficial infection rates were lower overall in the non-laminar flow theatre (2.2percnt; versus 4.7percnt;), with a significantly lower superficial infection rate for knee arthroplasty performed in the non-laminar flow theatre (2percnt; versus 6.9percnt;). The deep infection rates were similar (1.3percnt; vs 1.9percnt;) for both laminar and non-laminar flow theatre respectively. Revision rates for infection were similar between both groups (0.9percnt; in non-laminar flow theatre vs 0.3percnt; in laminar flow)

Whilst the causes of post-operative surgical site infection are multifactorial, our results demonstrate that at long –term follow-up, there was no increased risk of infection without laminar flow use in our theatre.

Purpose

Clavicular anatomy is variable and this has implications when osteosynthesis is undertaken especially while using the newer generation pre-contoured anatomical plates. This study aimed to examine the anatomy of the clavicle and its variations.

Methods

One hundred and forty three clavicles of unknown origin were analysed. Photographs were taken of each clavicle. A scale and electronic callipers were used to determine specific dimensions from six predefined areas of the bone. The length, diameters of the acromial and sternal heads, the diameter of the mid-clavicular segment and depths of both the medial and lateral curvatures were obtained.

Failure of conservative treatment for tennis elbow is an indication for surgical decompression. The Topaz® technique utilises radiofrequency to decompress(detension) the tendon and in addition, it is thought to stimulate angiogenesis thereby facilitating healing. Initially we reviewed the three month follow up of 25 tennis elbow decompressions performed using the Topaz® technique. The case notes were reviewed and findings recorded on a structured proforma. After a minimum of 1 year we re-reviewed the case notes to identify recurrences or patients requiring revision surgery. The majority of patients were aged between 35–50 years. 87% of patients had symptoms for more than 12 months and symptoms experienced were mainly pain (100%). All patients had a full trial of physiotherapy and had minimum of two steroid injections. At three month follow up symptoms were completely relieved or improved in 88%. All patients were given an open appointment to review if symptoms recurred. On review of the notes after a minimum of one year, 84% had no further clinic attendances. Four elbows re-attended with symptom recurrence, two underwent traditional open release and two declined revision surgery. In the two patients who declined further surgery, symptoms had resolved at one year. The results of the Topaz® technique are comparable to that of the results of the traditional release from the literature both in terms of success and problems. It would be important to compare it to the traditional release to gauge its benefits against the standard practice.
