The purpose of the study was to identify factors that affect the incidence of deep wound infection after hip fracture surgery.

Data from a hip fracture database of 7057 consecutively treated patients at a single centre was used to determine the relationship between deep wound sepsis and a number of factors. Fisher's exact test and the unpaired T test were used. All patients were initially followed up in a specialist clinic. In addition a phone call assessment was made at one year from injury to check that no later wound healing complications had occurred.

There were 50 cases of deep infection (rate of 0.7%). There was no significant difference in the rate of deep sepsis with regards to the age, sex, pre-operative residential status, mobility or mental test score of the patient. Specialist hip surgeons and Consultants have a lower infection rate compared with surgeons below Consultant grade, p=0.01. The mean length of anaesthesia was longer in the sepsis group (76minutes) compared to the no sepsis group (65minutes), this was significant, p=0.01. The patient's ASA grade and fracture type were not significant factors. The rate of infection in intracapsular fractures treated by hemiarthroplasty was significantly greater than those that had internal fixation, p=0.001. The rate of infection in extracapsular fractures fixed with an extra-medullary device was significantly greater than those fixed with an intra-medullary device, p=0.021. The presence of an infected ulcer on the same leg as the fracture was not associated with a higher rate of deep infection. In conclusion we have found that the experience (seniority) of the surgeon, the length of anaesthesia and the type of fixation used are all significant factors in the development of deep sepsis. These are all potentially modifiable risk factors and should be considered in the treatment of hip fracture patients.

The indication for rotator cuff repair in elderly patients is controversial.

Prospective data on 6905 consecutive hip fracture patients at a district general hospital were analysed to identify the risk factors for the development of deep infection post-operatively. The main outcome measure was infection beneath the fascia lata.

A total of 50 patients (0.7%) had deep infection. Operations by consultants or a specialist hip fracture surgeon had half the rate of deep infection compared with junior grades (p = 0.01). Increased duration of anaesthesia was significantly associated with deep infection (p = 0.01). The method of fracture fixation was also significant. Intracapsular fractures treated with a hemiarthroplasty had seven times the rate of deep infection compared with those treated by internal fixation (p = 0.001). Extracapsular fractures treated with an extramedullary device had a deep infection rate of 0.78% compared with 0% for those treated with intramedullary devices (p = 0.02).

The management of hip fracture patients by a specialist hip fracture surgeon using appropriate fixation could significantly reduce the rate of deep infection and associated morbidity, along with extended hospitalisation and associated costs.

Introduction: Nonunion is a relatively common complication seen in orthopaedic practice. The treatment of nonunion has traditionally been revision fixation with autogenic bone grafting. Here we present our results of nonunion treatment using Osteogenic Protein -1 (OP1) and allograft paste.

Material and Methods: Forty Eight Patients with resistant nonunion including atropic, hypertrophic and infected nonunion were treated with a composite of osteogenic protein-1 and allograft paste. The series consisted of 28 males and twenty females. Average age was 54 years. The average duration of preoperative symptoms was 26 months (range 4 to 52). 28 of 48 patients had an average of three prior failed surgical attempts at union (range 1 to 6). There were thirty seven atrophic, four hypertrophic and seven infected nonunions (bone transport docking site nonunion).18 patients in the series had previous autogenic cancellous bone grafting to the fracture site for attempted union. 39 patients had revision internal fixation with application of OP-1 and allograft paste to the nonunion site. Average healing time was 6.5 months (Range 3.5–19). Three patients in this series had OP-1 insertion twice, one patient simultaneously had autogenic cancellous bone grafting with OP-1.

Results: Average follow-up was 16 months (range 4 to 38). Functional and radiological outcome was excellent in 33 patients, good in five patients and fair in three. 3 cases were ongoing. Three patients went on to non-union requiring revision surgery and are under review. One patient died during follow-up.

Conclusion: Results in our series indicate OP-1 (BMP-7) implanted with Opteform allograft paste are as effective as autogenic cancellous bone grafting in treating resistant bone nonunions.

Background: Procedures performed at the incorrect anatomical site are perceived as rare events. However, they can be devastating for patients and doctors. In 2007, the Chief Medical Officer for England highlighted surgical site errors as an area of concern. Evidence from the UK and North America suggests that these events are more common than we think. We present our findings on the rates of surgical errors in England and Wales.

Methods: We obtained information from the National Patient Safety Agency (NPSA) and the NHS Litigation Authority (NHSLA) detailing reported cases of surgical error in England and Wales in the time period 1995–2007. This information was evaluated in conjunction with data detailing the total number of operations performed in England and Wales for the same time periods.

Results: Since 1995 there have been 292 cases of errors recorded on the NHSLA database. Orthopaedic surgery was the worst offending speciality with 87 cases (29.8%). There were 49 cases (16.8%) in dental surgery and 40 cases (13.7%) in general surgery. The most commonly affected sub-specialty area of orthopaedic surgery was the hand (21 cases), followed by foot and ankle (18 cases) and spine (16 cases). The total cost of the cases which have been settled was £2,252,752.58. For the year 2006–2007 the risk of an event in orthopaedic surgery was calculated to be 1 in 105,712 cases. The risk in general surgery and obstetrics and gynaecology during this period was 1 in 353,511 and 1 in 133,371 respectively.

Discussion: Orthopaedic procedures featured more commonly on the NHSLA database than any other specialty. Rates were also higher after adjustment for case load. We would like to draw attention to policies such as the WHO surgical safety checklist which aim to reduce the occurrence of such adverse incidents.

Introduction: The Taylor spatial frame (TSF) (Smith & Nephew) is a hexapod ring fixator that utilises the Ilizarov principles. The TSFs design is based on the Stewart-Gough platform, the use of which was originally described in mechanical engineering. Due to its unique design the TSF is extremely versatile in limb reconstruction surgery, allowing six degrees of freedom bone fragment manipulation with a high degree of precision that is aided by correction planning software.

Methods: Between October 2003 and December 2008 66 consecutive patients were treated using the TSF by a single consultant surgeon. Median patient age was 45 (range 20–69). The original pathology included 18 mal-unions, 13 acute fractures, 10 medial compartment osteoarthritis (OA) of the knee with varus deformity, 8 infected nonunions, 7 limb length discrepancies, 5 nonunions, 3 ankle OA, 3 post traumatic posterolateral corner of the knee instability, 1 multiple epiphyseal dysplasia, 1 lateral compartment OA of the knee with valgus deformity, 1 deformity secondary to Polio. There were 10 ankles, 19 knees (1 femur, 18 tibiae) and 37 tibiae.

Results: The procedures performed were 16 high tibial osteotomies, 2 frame assisted platings, 8 bone transports, 32 deformity corrections, 14 Ankle arthrodesis (9 primary, 5 revision after nonunion), 9 limb lengthening and 1 derotation. The median bone transport distance and lengthening achieved is reported.

The median time spent in the frame was 21 weeks (range 9–81), including 8 patients who required 2 frames to complete their treatment.

54 cases had a satisfactory outcome in terms of union and deformity correction using only the TSF, 5 cases were ongoing. Complications included 1 below knee amputation, 2 docking site nonunions requiring ORIF, 2 nonunions after ankle arthrodesis requiring T2 nails. 2 frames were removed due to compliance issues. 2 patients developed deformity requiring Tendo-achilles lengthening. There were 2 DVTs and 2 non-fatal PEs. 1 patient suffered a fracture at a femoral pin-site after TSF removal which was treated with external fixation. The median Otterburn grade of pin-site infection was 2 (range 0–4).

Conclusion: The Taylor spatial frame was used successfully in several different pathologies ranging from acute trauma to chronic deformity. The TSF provides the surgeon with a reliable treatment strategy that is both versatile and accurate.

In oncological resections there is a higher risk of infection around the foot and ankle. An infection here can be difficult to treat and easily lead to an amputation due to the limited amount of soft tissue coverage of the region. In three patients an infection developed after resection of a bone tumour in the foot and ankle.

In the first case, female 34 years, an epitheloid hemangioepithelioma was excised from the anterior part of the calcaneus, cuboid and lateral os cuneiform. An iliac crest graft was initially used to fill the defect, but got infected. The antibiotic loaded bone cement spacer cured the infection and filled the dead space but was painful. A free vascularised fibula with skin-flap was used successfully to fill the defect and take away the pain. At three-year follow-up there is no pain and full weight bearing, with a nice hypertrophy of the graft. In the second case, a 14-year old girl, there was an Aneu-rismal Bone Cyst (ABC) of the distal tibia with a deep infection after ethibloc injection. The vacuum assisted closure cleaned the wound but a defect resulted. It was successfully filled with an ipsilateral free vascularised fibula with skin-flap. Follow-up shows full function and nice hypertrophy at 24 months. In the third case, male 65 years, a chondrosarcoma grade one (after biopsy) in the cuboid was curetted out. It proved grade two in the definitive histology and furthermore it got infected. The cuboid was excised and a cement spacer was placed. The soft tissues were insufficient to close it properly. A free vascularised fibula with skin-flap was used. The vascularity of the graft was insufficient and the skin-flap did not survive. A vacuum assisted closure was done. He can bear weight and has no pain. The fibula graft is shows some hypertrophy and a fistula persists for 18 months now.

We conclude that vascularised free fibula with skinflap can successfully prevent amputation in case of infection in oncological resection of foot and ankle. The fibula reconstructs the bone defect and the skin-flap the soft tissue defect.

Introduction: The treatment of isolated medial compartment osteoarthritis (OA) in the young or physically active patient is a challenging problem for the orthopaedic surgeon.

The rationale for high tibial osteotomy (HTO) in medial compartment OA with varus deformity is to correct varus malalignment and to redistribute load to the non-diseased lateral compartment of the knee. Here we present our early to mid-term clinical and radiological findings.

Methods: Between October 2005 and April 2007 9 patients underwent HTO and TSF application. Pre-operative OA grade was recorded using the Ahlbäck classification. Radiographs were used to calculate the pre and post operative measurements for the tibiofemoral angle, the mechanical axis deviation and the tibial slope. Correction planning was carried out using the Spatialframe software package. All operations were performed by a single experienced consultant orthopaedic surgeon specialising in Ilizarov and limb reconstruction surgery. Pre and post-operative Oxford knee scores were collected for each patient.

Results: Median follow-up was 19 months (range 15–35). Median age at operation was 49 years (range 37–59). On preoperative radiographic examination eight knees were Ahlbäck grade 1 and one knee was Ahlbäck grade 2. The median time spent in the frame was 18 weeks (range 12–37). The median total angle of correction according to correction program given was 14 degrees (range 10–22) and the median duration of correction was 18 days (range 14–36) with 6 patients requiring an additional correction program.

2 patients subsequently underwent matrix induced autologous chondrocyte implant (MACI) for osteochondral defects.

In the primary OA group we found an improvement in mean Oxford knee score after HTO from 28.3 to 37.8/48 post-operatively. 1 patient was non-compliant with the correction and required a total knee replacement (TKR) for continued pain at 36 weeks post frame removal. 1 patient required fibular osteotomy during their correction.

6 (67%) of the 9 patients had a documented pin site infection. The median Otterburn grade was 3 (range 0–4). There were no cases of chronic bone infection.

Conclusions: High tibial osteotomy performed with the Taylor spatial frame presents a viable treatment option in active patients with early medial compartment OA. With TKR as an end point the survival rate of HTO for treatment of OA was 88.9% at a median of 19 months follow-up. Our results also indicate successful use of the technique in combination with MACI.
