We carried out a prospective study over a period of 12 months to measure the exposure to radiation of the hands of a dedicated foot and ankle surgeon. A thermoluminescent dosimeter ring (TLD) was used to measure the cumulative dose of radiation. Fluoroscopy was used in operations on the foot and ankle. The total screening time was 3028 s, with a mean time per procedure of 37.4 s (0.6 to 197). This correlated positively with the number of procedures performed (r = 0.92, p < 0.001), and with the dose of radiation in both the left (r = 0.85, p = 0.0005) and right TLDs (r = 0.59, p = 0.419). There was no significant difference in the dose of radiation between the two hands (t-test, p = 0.62). The total dose to the right TLD over the 12 months was 2.4 millisieverts. This is a simple and convenient method for evaluating the exposure of a single surgeon to radiation. The radiation detected was well below the annual dose limit set by the International Commission on Radiological Protection

Introduction:. Unstable ankle fractures are commonly treated with operative fixation. Isolated lateral malleolus fractures (Weber B) are often operated by orthopaedic trainees. Operative fixation of these fractures is included in the index procedures of procedure based assessment (PBA) of intercollegiate Surgical Curriculum Programme (ISCP). Orthopaedic trainees are expected to be competent in this procedure by the end of their training. Fluoroscopic guidance is essential for adequate reduction and safe fixation of these fractures. Aims:. It is currently unknown if patients are exposed to excess radiation when they are operated by trainees compared to consultant surgeons. It is a common perception that trainees take more time to fix these fractures compared to trained consultants thereby exposing patients to untoward effects of prolonged tourniquet time. Method:. A retrospective review of fifty patients undergoing operative fixation of Weber B lateral malleolus fractures were undertaken. Twenty five patients were operated by orthopaedic consultants and the remaining (n=25) by orthopaedic trainees. The tourniquet time and the intra-operative radiation dose using the fluoroscope were recorded. Results:. Patients operated by trainees were exposed to significantly higher dose of intra-operative radiation (median, 6.5 Gy vs 46.2 Gy; interquartile range, 0.87–15.8 vs 8.37–140.3; P=0.003). However, there was no statistical difference in the duration of application of the tourniquet in between the two groups (median, 59 minutes vs 79 minutes; interquartile range, 45–95 vs 69–102; P=0.12). Discussion:. This is the first study to indicate that patients are at risk of higher radiation exposure when operated by orthopaedic trainees whilst the times taken to fix Weber B ankle fractures are almost similar to those undergoing surgery by a consultant grade surgeon

Introduction:. Cone Based CT (CBCT) scanning uses a point source and a planar detector with parallel data acquisition and volumetric coverage of the area of interest. The pedCAT (Curvebeam USA) scanner is marketed as a low radiation dose, compact, faster and inexpensive CT scanner that can be used to obtain both non- weightbearing and true 3 dimensional weightbearing views. Method:. A review of the first 100 CBCT scanning in our unit has been performed to assess ease of scanning, imaging time, radiation dose and value of imaging as opposed to conventional imaging. Results:. A pedcat CT scan was available within minutes of the request, similar to plain radiographs but much earlier than a 6 week delay for a patient to attend a new appointment for a conventional CT. All patients returned to see the clinician for a clinical decision in the same NHS clinic and did not require a new clinic visit; illustrative cases include fracture/subluxation detection, surgical planning, extent of arthritis and 3D assessment of union of arthrodeses. All patients were able to transfer to the scanner with ease and the imaging time was 10 times than a conventional CT. The radiation dose to the patients was 9% that of a full gantry system. Weightbearing CT scanning enabled a 3D evaluation of reduction of joint space and ankle/hindfoot alignment. Anterior ankle and sesamoid impingement have been diagnosed in patients with previously obscure pain. Conclusion:. 3D Cone Beam imaging has been found to be easily accessible, rapidly performed and safer to the patient in providing a lower radiation dose. Weightbearing 3D imaging provides additional diagnostic information

Aims

Arthroplasty has become increasingly popular to treat end-stage ankle arthritis. Iatrogenic posterior neurovascular and tendinous injury have been described from saw cuts. However, it is hypothesized that posterior ankle structures could be damaged by inserting tibial guide pins too deeply and be a potential cause of residual hindfoot pain.

Introduction:. Instability and synovitis of the lesser metatarsalphalangeal (MTP) joints is a significant cause of forefoot pain. Plantar plate imaging traditionally has been through MRI and fluoroscopic arthrography. We have described ultrasound arthrography as a less resource-intensive technique without radiation exposure. We report the correlation between ultrasound arthographic and surgical findings. Methods:. Patients with lesser MTP joint instability and pain underwent ultrasound arthrography by a consultant musculoskeletal radiologist. The main finding was the presence of a full or partial tear of the plantar plate. In some patients the location of the tear along with its size in the long and short axis was also reported. Authors who were not involved in the imaging or surgery reviewed the operation notes of patients who underwent surgery to identify. Whether a partial or full thickness tear was identified. Size and location of the tear. The accuracy of ultrasound arthrography was calculated using surgical findings as the standard. Results:. 53 patients with 55 joints underwent ultrasound arthrography, and of these 34 went on to have surgery. 23 patients had adequate documentation of surgical and ultrasound findings. Surgery confirmed plantar plate tears in 21 patients (91.3%) with 9 full thickness tears and 7 partial thickness tears confirmed both operatively and with ultrasound (in 5 patients the operation note did not specify completeness of tear). In 2 patients, in whom ultrasound demonstrated a partial thickness tear, no tear was found at surgery. The sensitivity of ultrasound arthrography for plantar plate tears is 100%, specificity is 0% (although based on few patients), and positive predictive value of 91.3%. Conclusion:. Ultrasound arthrography has a high sensitivity, but low specificity for plantar plate tears, comparable with ultrasound in previous studies. It allows differentiation of partial and full thickness tears which may be important for treatment

Introduction. Patients who present with atypical foot pain in a non specific sensory distribution may benefit from having nerve conduction studies (NCS). The aim of this study was to confirm whether NCS is a useful tool. Methods. Between July 2005 and March 2011, 78 patients had NCS to investigate foot pain. The management following NCS was compared with the initial management plan. Results. Complete data was available for 60 patients, of whom 31 were male. The mean age at presentation was 54.4 years (range 18–89.7). Eighteen patients had bilateral symptoms. The predominant symptom was pain in 47 patients. Aching, burning, throbbing, shooting, pins and needles, proximal/distal radiation, numbness, and paraesthesia were also described in 23 patients. Twenty patients had a history of trauma and five developed symptoms following elective lower limb surgery. Eight patients had a cavovarus foot. There were 22 normal results. The NCS diagnosed peripheral nerve (13)/nerve root (8) pathology, Charcot-Marie-Tooth (1), amyotrophic lateral sclerosis (1), tarsal tunnel syndrome (3), and nonspecific neuropathy (12). Surgery was initially considered for 9 patients. Following a normal result, 4 out of 7 had surgery. One patient with an abnormal result proceeded to surgery. The NCS was abnormal in 70.1% (36/51) of patients who were for nonoperative management, 4 of whom proceeded to have surgery. None of the patients who had a normal NCS had an operation. Conclusion. NCS provided a diagnosis for 63.3% of the patients. Following NCS, the management plan changed in 44% of patients who were initially considered for surgery (4/9) and in 7.8% of patients who were initially considered for nonoperative management (4/51). This investigation is a useful adjunct in guiding the management of patients who present with atypical non specific foot pain

Injury to the syndesmosis occurs in approximately 10% of all patients with ankle fractures. Anatomic restoration of the syndesmosis is the only significant predictor of functional outcome. Several techniques of syndesmosis fixation are currently used such as cortical screws, bioabsorbable screws and more recently introduced suture-button fixation. No single technique has been shown to be superior to the others. The objective of this research project is to investigate whether treatment with a tightrope (suture-button fixation) gives superior results than the use of a cortical screw in the treatment of acute syndesmotic ankle injuries with regards to function, pain, satisfaction and return to normal activities. Research Ethics Committee approval was obtained. 40 patients with syndesmotic ankle injuries associated with diastasis were prospectively recruited, 20 in each group. Patients were randomized to one of the 2 groups. At 12 weeks, American Orthopaedic Foot and Ankle Society (AOFAS) scores and a computerized tomography (CT) scan of both the ankles was obtained. At 1 year, AOFAS scores and satisfaction was assessed. 32 patients have been recruited so far, 20 in the tightrope group and 12 in the cortical screw group. Mean AOFAS scores at 3 months post-op were 90.67 in the Tightrope group and 84 in the screw group. The difference was not significant (p= 0.096). CT scans revealed that the quality of syndesmosis reduction was equally good with both the techniques. Metalwork prominence was common with both the devices. Discussion and Conclusion. Both the devices achieved good reduction of the syndesmosis. Our CT scan protocol has insignificant radiation risk and allows more accurate assessment of the syndesmosis. Early clinical results do not show a significant difference in the functional outcome with the use of either device. Long-term (1 year) follow-up has been planned

Introduction. Ottawa ankle rules originally described in 1992 have been shown to improve the pick-up rates of ankle fractures and avoid the need for unnecessary X-rays, thus minimising cost and radiation to the patient. We decided to carry out an audit at our hospital to look at the pick-up rates of ankle fractures and ways to minimise x-rays for the patient both in A&E and in the orthopaedic department. Methods. Ankle x-rays of 1088 trauma patients over a 7 month period from Dec 2009 to June 2010 (inclusive) were reviewed. Patients with ankle fractures were classified according to Weber type, and whether they were treated surgically or non-operatively. Non-operatively treated ankle fractures then formed the main sub-group of our study, looking at the number of follow-up X-rays and the amount of subsequent displacement. The amount of displacement was classified into non-displaced (0 mm), minimally displaced (<2mm) and displaced (>2 mm). Results. 171 patients (out of 1088) were found to have fractured their ankle giving a pick up rate of 16%. (cf a pickup rate of 26% described in literature with implementation of Ottawa rules). The pick up rate fluctuated each month from 31% in December to a meagre 6% fractures in June and this could be due to summertime sports injuries causing less fractures and more sprains. We noted a third more x-rays were ordered in Spring than Winter. There were no changes in junior staff in either the A&E or the orthopaedic department to account for the monthly variations. Conservatively managed fractures were followed up in the fracture clinic (n = 95, 56%) 16% (n = 11) of the conservatively managed patients were classified as Weber A fractures 84% (n=58) as Weber B fractures. No Weber C fractures were conservatively managed. Of the eleven Weber A fractures only one was minimally displaced. Conservatively managed Weber A fractures received an average of 1.36 x-rays on follow up in the Orthopaedic department. Of the Weber B fractures 42 were non-displaced whilst 16 were minimally displaced, and these received an average of 3.23 x-rays on follow up. None of these progressed to displacement > 2mm. Conclusion. Based on our audit, we have introduced a policy to limit the number of follow-up of X-rays for minimally displaced and undisplaced Weber A & B fractures to one. We have also re-emphasized the importance of Ottawa rule implementation in our A&E department

The last decade has seen a considerable increase in the use of in total ankle arthroplasty (TAA) to treat patients with end-stage arthritis of the ankle. However, the longevity of the implants is still far from that of total knee and hip arthroplasties.

The aim of this review is to outline a diagnostic and treatment algorithm for the painful TAA to be used when considering revision surgery.

We conducted a randomised controlled trial to determine whether active intense pulsed light (IPL) is an effective treatment for patients with chronic mid-body Achilles tendinopathy. A total of 47 patients were randomly assigned to three weekly therapeutic or placebo IPL treatments. The primary outcome measure was the Victorian Institute of Sport Assessment – Achilles (VISA-A) score. Secondary outcomes were a visual analogue scale for pain (VAS) and the Lower Extremity Functional Scale (LEFS). Outcomes were recorded at baseline, six weeks and 12 weeks following treatment. Ultrasound assessment of the thickness of the tendon and neovascularisation were also recorded before and after treatment.

There was no significant difference between the groups for any of the outcome scores or ultrasound measurements by 12 weeks, showing no measurable benefit from treatment with IPL in patients with Achilles tendinopathy.

Supination-external rotation (SER) fractures of the ankle may present with a medial ligamentous injury that is not apparent on the initial radiographs. A cadaver gravity-stress view has been described, but the manual-stress view is considered to be the examination of choice for the diagnosis of medial injuries. We prospectively compared the efficacy of these two examinations.

We undertook both examinations in 29 patients with SER fractures. Of these, 16 (55%) were stress-positive, i.e. and had widening of the medial clear space of > 4 mm with a mean medial clear space of 6.09 mm (4.4 to 8.1) on gravity-stress and 5.81 mm (4.0 to 8.2) on manual-stress examination, and 13 patients (45%) were stress-negative with a mean medial clear space of 3.91 mm (3.3 to 5.1) and 3.61 mm (2.6 to 4.5) on examination of gravity- and manual-stress respectively. The mean absolute visual analgoue scale score for discomfort in the examination of gravity stress was 3.45 (1 to 6) and in the manual-stress procedure 6.14 (3 to 10).

We have shown that examination of gravity-stress is as reliable and perceived as more comfortable than that of manual stress. We recommend using it as the initial diagnostic screening examination for the detection of occult medial ligamentous injuries in SER fractures of the ankle.
