We studied prospectively 30 patients who had a Mitchell’s osteotomy secured by either a suture followed by immobilisation in a plaster boot for six weeks, or by a cortical screw with early mobilisation.

The mean time for return to social activities after fixation by a screw was 2.9 weeks and to work 4.9 weeks, which was significantly earlier than those who had stabilisation by a suture (5.7 and 8.7 weeks, respectively; p < 0.001). Use of a screw also produced a higher degree of patient satisfaction at six weeks, and an earlier return to wearing normal footwear. The improvement in forefoot scores was significantly greater after fixation by a screw at six weeks (p = 0.036) and three months (p = 0.024). At one year, two screws had been removed because of pain at the site of the screw head.

Internal fixation of Mitchell’s osteotomy by a screw allows the safe early mobilisation of patients and reduces the time required for convalescence.

Akins original description of his osteotomy did not describe the use of any metal work. Today the osteotomy is most commonly held and fixed with either a staple or screw. We describe the results obtained with a simple suture technique. Methods Data was collected prospectively on 125 patients undergoing an Akin osteotomy. Hallux valgus (HV) and intermetatarsal (IM) angles pre and postoperatively were recorded. Patients were reviewed at 6 week follow up. Cost analysis was also performed comparing different fixation types.

111 of the patients were female and 14 male. The average age at time of surgery was 49 years. 104 cases were in conjunction with hallux valgus correction while 21 cases were for hallux interphalangeus. The mean preoperative HV angle was 33.3 degrees (range 22 to 53), and the IM angle 13.3 degrees (range 9 to 25). At the 6 week follow up all patients had shown signs of radiological union. The postoperative HV angle was 12.4 degrees (range 7 to 17) and the IM angle 6.4 degrees (range 5 to 11). All patients maintained their correction. There were no complications, infections or fixation problems. All patients were satisfied with their surgery and would have it repeated again. The suture technique was the most cost effective method.

We describe a quick, easy, implant free method of fixing the Akin osteotomy. There is no need for metalwork removal and in today's world of austerity and the current climate of widespread budget constraints we describe a cost effective method which is clinically just as effective as methods requiring a staple or screw.

Introduction. Syndesmosis injuries are significant injuries and require anatomical reduction. However, stabilisation of these injuries with syndesmosis screws carries specific complications and many surgeons advocate a second operation to remove the screw. Primary Tightrope suture fixation has been shown to be an effective treatment for syndesmotic injuries and avoids the need for a second operation. Materials and Methods. A retrospective audit identified patients who were treated for syndesmosis injuries over a two year period. Theatre and clinic costs were obtained to compare the cost of syndesmosis fixation using diastasis screws with the estimated cost of primary syndesmosis fixation using a Tightrope suture. Results. 79 patients received diastasis screw fixation of syndesmosis injuries between January 2007 and January 2009. The mean number of follow up clinic appointments was 3.7 following initial surgery, and 2.2 following diastasis screw removal. Allowing for device, theatre time and clinic appointment costs, and an estimated average of 4 follow up appointments following Tightrope syndesmosis fixation, primary fixation with this device could a saving of 34 theatre slots, 68 outpatient clinic appointments, and £12,138 per year at our hospital. Discussion. Biomechanical studies have demonstrated a reduction in normal tibiotalar external rotation with the presence of a diastasis screw, and there are several published reports of complications when these screws are retained. The Tightrope suture provides reduction of the syndesmosis whilst allowing normal physiological movement at the distal tibiofibular joint and negates the need for a second operation to remove the implant. In addition there may be improvements in foot and ankle scores and a faster return to work when these devices are used compared with traditional screw fixation. Conclusion. In addition to the patient benefits, our audit suggests that there may be significant financial benefits associated with primary syndesmosis fixation with Tightrope sutures

Aims

The traditional transosseus flexor hallucis longus (FHL) tendon transfer for patients with Achilles tendinopathy requires two incisions to harvest a long tendon graft. The use of a bio-tenodesis screw enables a short graft to be used and is less invasive, but lacks supporting evidence about its biomechanical behaviour. We aimed, in this study, to compare the strength of the traditional transosseus tendon-to-tendon fixation with tendon-to-bone fixation using a tenodesis screw, in cyclical loading and ultimate load testing.
