Introduction. Cheilectomy is a recommended procedure for the earlier stages of osteoarthritis of the 1. st. metatarsophalangeal joint. Although good improvement in symptoms have been reported in many studies, the long term performance of this procedure is not well understood. It is thought that a significant number of patients go onto have arthrodesis or joint replacement. We report on a large cohort of patients who received this procedure and report on the complications and mid-term outcome. Methods. This is a retrospective study looking at all patients who underwent cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to access patient details and outcome measures recorded include: postoperative wound infection, patient reported improvement in pain and the incidence of further surgical interventions like revision cheilectomy and conversion to arthrodesis and arthroplasty. X-rays were studied using PACS to stage the osteoarthritis (Hattrup and Johnson classification). Results. A total of 240 feet in 220 patients (20 bilateral surgeries) were included in the study, there were 164 Females (75%) and 56 Males (25%), the median age was 55 years (range 22–90 years). Radiological assessment showed 89 Stage 1 arthritis(42%), 105 Stage 2 (50%), 17 Stage 3 (8%) and 9 patients were excluded due to unavailable X-rays. 5 patients (2%) had superficial wound infection. There were 16 further surgeries (7%) performed in this cohort, 12 arthrodesis (5%), 3 revision cheilectomy and 1conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to unavailable data. Conclusion. Cheilectomy appears to produce good improvement in pain with a low complication rate. The rate of conversion to arthrodesis/arthroplasty is lower than in many reported studies

Tendoscopy in the treatment of peroneal tendon disorders is becoming an increasingly safe, reliable, and reproducible technique. Peroneal tendoscopy can be used as both an isolated procedure and as an adjacent procedure with other surgical techniques. The aim of our study was to review all peroneal tendoscopy that was undertaken at the AOC, by the senior authors (IGW, SH), and to determine the safety and efficacy of this surgical technique. Methods. From 2000 to 2017 a manual and electronic database search was undertaken of all procedures by the senior authors. Peroneal tendoscopy cases were identified and then prospectively analysed. Results. 51 patients (23 male, 28 female) were identified from 2004–2017 using a manual and electronic database search. The mean age at time of surgery was 41.5 years (range 16–83) with a mean follow-up time post operatively of 11.8 months (range 9–64 months). The main indications for surgery were lateral and/or postero-lateral ankle pain and lateral ankle swelling. The majority of cases showed unstable peroneal tendon tears that were debrided safely using tendoscopy. Of the 51 patients, 23 required an adjacent foot and ankle operation at the same time, 5 open and 17 arthroscopic (12 ankle, 5 subtalar). Open procedures included 2 first ray osteotomies, 2 open debridements of accessory tissue, one PL to PB transfer. One patient also had an endoscopic FHL transfer. Complication rates to date have been low: 2 superficial wound infections (4%) and one repeat tendoscopy for ongoing pain. A small proportion of patients with ongoing pain were treated with USS guided steroid injections with good results. Conclusion. Our series of peroneal tendoscopy has a low complication rate with high patient satisfaction at discharge. Results of tendoscopic treatment are similar to open techniques, however its advantages make tendoscopic procedures an excellent method to treat peroneal tendon disorders

Aims. Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm. 2. However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus. Methods. Patients were randomly enrolled into two groups. At three weeks postoperatively, the rESWT group was given shockwave treatment, once every other day, for five treatments. In the control group the head of the device which delivered the treatment had no energy output. The two groups were evaluated before surgery and at six weeks and three, six and 12 months postoperatively. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Secondary outcome measures included a visual analogue scale (VAS) score for pain and the area of bone marrow oedema of the talus as identified on sagittal fat suppression sequence MRI scans. Results. A total of 40 patients were enrolled and randomly divided into the two groups, with 20 in each. There was no statistically significant difference in the baseline characteristics of the groups. No complications, such as wound infection or neurovascular injury, were found during follow-up of 12 months. The mean AOFAS scores in the rESWT group were significantly higher than those in the control group at three, six, and 12 months postoperatively (p < 0.05). The mean VAS pain scores in the rESWT group were also significantly lower than those in the control group at these times (p < 0.05). The mean area of bone marrow oedema in the rESWT group was significantly smaller at six and 12 months than in the control group at these times (p < 0.05). Conclusion. Local shockwave therapy was safe and effective in patients with osteochondiritis of the talus who were treated with a combination of arthroscopic surgery and rESWT. Preliminary results showed that, compared with arthroscopic microfracture alone, those treated with arthroscopic microfracture combined with rESWT had better relief of pain at three months postoperatively and improved weightbearing and motor function of the ankle.

Introduction:. We report our 10-year experience of post-operative complications of calcaneal fractures treated by internal fixation and attempt to correlate these with previously cited patient risk factors. Methods:. All calcaneal fractures treated by internal fixation in our Major Trauma Centre between September 2002 and September 2012 were identified. Patient indices (age, gender, smoking status and pre-existing co-morbidities), time to surgery and method of surgery (open reduction and internal fixation (ORIF) versus closed reduction and percutaneous fixation) were recorded. Primary outcome was the incidence of wound infection requiring intravenous antibiotics and/or re-operation. Statistical analysis through Mann-Whitney-Wilcoxon testing and relative risk ratio calculations with 95% Confidence Intervals (CI) was performed. Results:. 98 calcaneal fractures in 92 patients were identified. 79 (80.6%) fractures occurred in males, 19 (19.4%) in females. 54 (55.1%) were smokers and 44 (44.9%) non-smokers. 18 (18.4%) were treated by closed reduction and percutaenous fixation and 80 (81.6%) by ORIF. 3 (3.1%) patients (all male) developed post-operative wound infection (RR 0.96, 95% CI 0.92–1.00), of which 1 was a smoker (RR 1.03 95% CI 0.95–1.11). All infections occurred in patients treated percutaneously (RR 6.33, 95% CI 3.99–10.08). There was no significant difference in mean time to surgery (p=0.069) and mean age (p=0.31) for those patients experiencing wound complications and those who did not. Conclusions:. This study reports an overall wound infection rate in keeping with current literature. There was no statistically significant increased risk of wound infection in smokers or male patients. All infections occurred in patients who had percutaneous treatment. These findings support the continued treatment of displaced calcaneal fractures by open reduction and internal fixation through a conventional extended lateral approach. There is no justification in denying surgery to males or smokers although these two factors have been cited as poor prognostic indicators in earlier studies

Aims. Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise. Patients and Methods. We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as amputation, mortality and functional outcomes was determined. Results. Two patients developed lateral side wound infection, one of whom underwent wound debridement. Three other patients required re-operation for removal of symptomatic hardware. No patient required a below-knee amputation. Six patients died during the study period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short Form-36 Mental Component Score and Physical Component Score were 53.2 (95% confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale total score was 32.9 (95% CI 16.0 to 49.7). Conclusion. Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.

Introduction. Ankle replacement is a major surgery with significant soft tissue dissection and bleeding. The skin quality is often poor in these patients due to age, edema, venous congestion, arteriopathy or previous procedures and soft tissue injury. The chances of wound infection increase with delayed wound healing. Absorbent non-adherent dressing (ABD) and VAC dressing applied in theatre after ankle replacement were assessed in a cohort of 147 patients with wound complications, pain, satisfaction and length of stay as outcome measures. Patients and methods. 71 consecutive patients were treated with ABD post-operatively after ankle replacement. The practice was then changed to VAC dressings for 76 consecutive patients. 44 patients had additional procedures performed with ankle replacement (11 from ABD group and 33 from VAC group). Retrospective analysis of prospectively collected data was performed. All patients had daily pain score, wound status, hospital stay, satisfaction and range of movement recorded. Results. Patients with VAC had mean pain score of 3/10 post operatively compared with 6/10 with ABD. There was a significant difference between the length of stay between the groups (p=0.02). The average stay of stay was 9 days with ABD and 7 days with VAC dressing. One of the patients with VAC dressing had blisters and 1 patient developed a superficial wound infection. Of the ABD group, 3 patients developed blisters and 7 patients had wound complications after ABD. Range of movement was similar in both groups of patients. Patient's satisfaction with VAC dressing was 8/10. Conclusion. VAC is better than ABD as primary dressing after ankle replacement

Aims

The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture.

Aims

The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques.

Aims

Venous thromboembolism (VTE) is a potential complication of foot and ankle surgery. There is a lack of agreement on contributing risk factors and chemical prophylaxis requirements. The primary outcome of this study was to analyze the 90-day incidence of symptomatic VTE and VTE-related mortality in patients undergoing foot and ankle surgery and Achilles tendon (TA) rupture. Secondary aims were to assess the variation in the provision of chemical prophylaxis and risk factors for VTE.

Introduction. Flexor Hallucis Longus (FHL) tendon transfer is a well-recognised salvage operation for irreparable tendon Achilles (TA) ruptures and intractable Achilles tenonopathy. Several case series describes the technique and results of arthroscopic FHL tendon transfers. We present a comparative case series of open and arthroscopic FHL tendon transfers from Southmead Hospital, Bristol, UK. Methods. For the arthroscopic FHL transfers in most cases the patients were positioned semi prone with a tourniquet. A 2 or 3 posterior portal technique was used and the tendon was secured using an RCI screw. The rehabilitation was similar in both groups with 2 weeks in an equinus backslab followed by gradual dorsiflexion in a boot over the following 6 weeks. Anticoagulation with oral aspirin for 6 weeks was used. A retrospective case note review was performed. Results. There were 12 arthroscopic (8 males, 4 female) and 16 open procedures (9 male, 7 female). Both had a mean age of 56. 1 arthroscopic FHL was lost to follow up. There were no concomitant procedures in the arthroscopic group. In the open group the TA was repaired in 7 cases (3 of these involved z-shortening). There was 1 plantaris interposition, 1 V-Y advancement and 1 gastrocnemius advancement. Degenerate tendon was excised in 1 severe re-rupture of a calcified tendinopathic achilles. There was no difference in tourniquet time between the groups (arthroscopic 69mins vs open 64 mins, p=0.64). There were no complications in the arthroscopic group. In the open group there was 1 superficial wound infection, 1 nerve injury & 1 delayed DVT at 3 months. Conclusion. Arthroscopic FHL transfer is a safe and effective surgical option when no other achilles procedures are required. The soft tissue insult is minimal, making it a good option for patients with poor soft tissues or neurovascular compromise

Aims

Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR.

Aims. Involvement of the posterior malleolus in fractures of the ankle probably adversely affects the functional outcome and may be associated with the development of post-traumatic osteoarthritis. Anatomical reduction is a predictor of a successful outcome. The purpose of this study was to describe the technique and short-term outcome of patients with trimalleolar fractures, who were treated surgically using a posterolateral approach in our hospital between 2010 and 2014. Patients and Methods. The study involved 52 patients. Their mean age was 49 years (22 to 79). There were 41 (79%) AO 44B-type and 11 (21%) 44C-type fractures. The mean size of the posterior fragment was 27% (10% to 52%) of the tibiotalar joint surface. Results. Reduction was anatomical in all patients with a residual step in the articular surface of ≤ 1 mm. In nine of the C-type fractures (82%), the syndesmosis was stable after fixation of the posterior fragment and a syndesmosis screw was not required. Apart from one superficial wound infection, there were no wound healing problems. At a mean radiological follow-up of 34 weeks (seven to 131), one patient with a 44C-type fracture had widening of the syndesmosis which required further surgery. Conclusion. We conclude that the posterolateral surgical approach to the ankle gives adequate access to the posterior malleolus, allowing its anatomical reduction and stable fixation: it has few complications. Take home message: Fixation of the posterior malleolus in trimalleolar fractures can be easily done via the posterolateral approach whereby anatomical reduction and stable fixation can be reached due to adequate visualisation of the fracture.

Traditional open approaches for subtalar arthrodesis have reported nonunion rates of 5–16% and significant incidence of infection and nerve injury. The rationale for arthroscopic arthrodesis is to limit dissection of the soft tissues in order to preserve blood supply for successful fusion, whilst minimising the risk of soft tissue complications. The aim of this study was to determine the outcomes of sinus tarsi portal subtalar arthrodesis. Case records of all patients undergoing isolated arthroscopic subtalar arthrodesis by two senior surgeons between 2004 and 2014 were examined. All patients were followed up until successful union or revision surgery. The primary outcome measure was successful clinical and radiographic union. Secondary outcome measures included occurrence of infection and nerve injury. Seventy-seven procedures were performed in 74 patients, with successful fusion in 75 (97.4%). One (1.3%) superficial wound infection and one (1.3%) transient sural nerve paraesthesia occurred. Fixation with a single screw provided sufficient stability for successful arthrodesis. To our knowledge this is the largest reported series of isolated arthroscopic subtalar arthrodeses to date, and the first series reporting results of the two portal sinus tarsi approach. This approach allows access for decortication of all three articular facets, and obviates the need for a posterolateral portal, features which may explain the high union rate and low incidence of sural nerve injury in our series

Lisfranc fracture dislocations of the midfoot are uncommon but serious injuries, associated with posttraumatic arthrosis, progressive deformity, and persistent pain. Management of the acute injury aims to restore anatomic tarsometatarsal alignment in order to minimise these complications. Reduction and stabilisation can be performed using image-guided percutaneous reduction and screw stabilisation (aiming to minimise the risk of wound infection) or through open plating techniques (in order to visualise anatomic reduction, and to avoid chondral damage from transarticular screws). This retrospective study compares percutaneous and open treatment in terms of radiographic reduction and incidence of early complications. Case records and postoperative radiographs of all patients undergoing reduction and stabilisation of unstable tarsometatarsal joint injuries between 2011 and 2014 in our institution were reviewed. Dorsoplantar, oblique and lateral radiographs were assessed for accuracy of reduction, with malreduction being defined as greater than 2mm tarsometatarsal malalignment in any view. The primary outcome measure was postoperative radiographic alignment. Secondary outcome measures included the incidence of infection and other intra- or early postoperative complications. During the study period, 32 unstable midfoot injuries were treated, of which 19 underwent percutaneous reduction and screw stabilisation and 13 underwent open reduction and internal fixation. Of the percutaneous group, no wound infections were reported, and there were four (21.1%) malreduced injuries. Of the open group, two infections (15.4%) were observed, and no cases of malreduction. In conclusion, our study shows a strong trend towards increased risk of malreduction when percutaneous techniques are used to treat midfoot injuries, and an increased risk of infection when open surgery is used. Whilst conclusions are limited by the retrospective data collection, this study demonstrates the relative risks to consider when selecting a surgical approach

Background:. Calcaneal osteotomy is an established technique in correcting hind foot deformity. Patients have traditionally received an open osteotomy through Atkins lateral approach. In order to reduce the rate of wound complications associated with the Atkins approach, a minimally invasive surgical (MIS) technique has been adopted since 2011. This uses a low-speed, high-torque burr to perform the same osteotomy under radiographic guidance. The results of the new MIS technique, including post-operative complication rates, are compared to the standard open approach. Methods:. The safety of the new MIS technique was investigated by conducting a case controlled study on all patients who underwent displacement calcaneal osteotomy at the Nuffield Orthopaedic Centre, Oxford from 2008 to 2014. The primary outcome measure was 30 day post-operative complication rate. Secondary outcome measures included operating time, duration of stay, fusion rates and amount of displacement achieved. Results:. 82 patients underwent calcaneal osteotomy as part of their corrective surgery; 50 patients in the Open approach group and 32 patients in MIS group. The average age at the time of surgery was 47.7 years (range 16–77) for the Open group and 48.5 (range 21–77) in the MIS group. A mean calcaneal displacement of 8.0mm (s.d. 1.32, 7 to 11 mm) and 8.33mm (s.d.1.53, 6 to 10 mm) was achieved through the MIS and open approaches respectively. There were significantly fewer wound complications in the MIS group (6.25%) compared to the Open group (28%, P=0.021) and the MIS group was associated with significantly lower rates of wound infection (3% versus 20%, P = 0.043). Three patients in the Open group experienced sural peripheral neuropathy. Conclusions:. MIS calcaneal osteotomy was found to be a safe technique. It was as effective as calcaneal osteotomy performed through an open lateral approach but was associated with significantly fewer wound complications and fewer nerve complications

Introduction:. Historically the incidence of Achilles re-ruptures has been described as around 5% after surgical repair and up to 21% after conservative management. In 2008 we commenced a dedicated Achilles tendon rupture clinic for both conservative and surgically managed patients using new standardised operating procedures (SOP). We have evaluated the impact of this new service, particularly with regard to re-rupture rate. Materials and methods:. The SOP was stage dependent and included an initial ultrasound examination, functional orthotics with early weight bearing, accelerated exercise and guidelines for the return to work and sport. Evaluation included re-rupture rate, complication rate, and outcome measured by the Achilles Tendon Total Rupture Score (ATRS) and Achilles Tendon Repair Score (AS). A basic cost evaluation was performed to assess any potential savings. Results:. A total of 213 patients (151 treated conservatively and 62 surgically) were included. Re-rupture occurred in two patients (1 conservative and 1 surgically managed). There were 16 major complications e.g. DVT, wound infection. The mean ATRS was 54.79, 67.66 and 71.05 at 4, 6 and 9 months respectively and the mean AS was 64.67, 73.96 and 71.05 at 4, 6 and 9 months respectively. The reduction in re-rupture compared to the literature was 4.1% and 19.1% for surgical and conservatively treated patients respectively. Cost savings achieved were £50,000 each annum. This was due to both a decrease in the number of re-ruptures as well as a decrease in the number of patients being managed operatively. Conclusion:. A dedicated follow up Achilles clinic treating acute Achilles tendon ruptures using monitored SOP's, provides an exceptionally low re-rupture rate (0.9%), excellent patient outcome and potential cost savings compared to a traditional fracture clinic approach. The reduction in re-rupture rate, and therefore cost savings, is greater in conservatively managed patients

Introduction:. The aim of this study was to identify the rate of complications of total ankle replacement in a single Centre to help with informed patient consent. Methods:. Between 2008 and 2012, 202 total ankle replacements (TARs) were performed by 4 surgeons at our Institute. Data was collected on all patients; demographics, arthritic disease, pre-operative deformity, prosthesis and all early and late complications. Results:. 4 surgeons (A, B, C, D) performed 63, 55, 48 and 36 TARs (178 De Puy Mobility and 24 Corin Zenith). 130 patients had primary osteoarthrosis, 35 had rheumatoid and 36 had post traumatic osteoarthrosis. There were no differences in patient demographics for each surgeon. There were 3 deep infections (A, B, C, D: 1,0,2,0). There were 18 medial malleolar fractures (8 intra-operative [4,1,1,2], 3 early (< 3 months) [1,1,0,1] and 7 late (> 3 months) [2,2,2,1]). There were 2 lateral malleolar fractures, both intra-operative (0,0,1,1). There were 15 patients who developed superficial wound infections, which resolved fully with oral antibiotics (4,3,4,4). A further 7 patients had a delay to wound healing (wound not fully healed at 3 months) (4,0,2,1); 2 of these developed deep infection and failed. 22 patients had persistent medial gutter pain (9,4,5,4); all had undergone Mobility TAR. 4 patients developed recurrent edge loading and have had to be revised (4 converted to TTC fusion) (2,0,2,0). We report complications in 32% of patients. Overall 9 TARs failed and underwent revision to fusion (2,2,5,0). Conclusion:. We report an overall complication rate of 32% following TARs, however most are minor and don't affect clinical outcome. We had a 1.5% deep infection rate. Complication rates were comparable between 4 surgeons. There was a difference in medial gutter pain rate between implants (13% v 0% Mobility to Zenith). This data provides detailed complication rates for informed consent

Aim. A prospective cohort of patients undergoing total ankle arthroplasrty for arthritis following pilon fractures was included in the present study. This group of patients generally have poor soft tissue envelope and have had previous surgical interventions prior to the ankle arthroplasty, making the arthroplasty more difficult as well as prone to complications. Methods. The data collected included patient demographics, American Orthopaedic Foot and Ankle Score (AOFAS) and patient reported outcomes (FAOS, SF-36, patient satisfaction) The data was collected preoperatively and at 1 & 2 years postoperatively. The minimum follow-up period was 2 years post-operatively. Results. A total of 167 total ankle arthroplasties were performed by the senior author between Jan 2006 and June 2010. Of this cohort, the indication for 12 arthroplasties was arthritis following pilon fractures of the distal tibia. The average of the patients at the time of the surgery was 64.2yrs. The average number of previous surgeries prior to the ankle arthroplasty was 1.5. There were significant improvements in the AOFAS scores from an average of 18 to 75 at final review. The WOMAC scores improved from 31 to 71 for pain, stiffness improved from 31 to 60 and function improved from 33 to 63. The improvement of the SF36 and patient satisfaction score is similar to the ones for primary ankle osteoarthritis. The complications were: 1 case of superficial wound infection which settled with antibiotics, one fracture of medial malleolus and one case of undisplaced distal tibial fracture treated conservatively to union. Conclusion. The Indications for TAR can be safely broadened to include younger patients with arthritis following pilon fractures of the tibia. The Outcomes after TAR for patients with arthritis following pilon fractures are comparable to those for primary osteo arthritis of the ankle

Total ankle replacement (TAR) is increasingly offered as an alternative to ankle fusion for the management of severe ankle arthritis. As with all other types of joint arthroplasty, there are risks involved and complications that occur; these increase with case complexity. We present the complications and management from a single-centre series. Since 2006, we have performed 150 Mobility TARs with up to 4 years' follow-up. We have excluded 16 that are part of a separate RCT and 10 with less than 3 months' follow-up. 124 TARs were included in our study (117 patients). Three ankles (2.4%) had superficial wound infections treated successfully with antibiotics. One ankle (0.8%) required an arthroscopic washout and debridement but the implant was retained. 11 ankles (8.9%) had a periprosthetic fracture: One was intraoperative; 10 were postoperative (2 fixed). Four patients (3.2%) developed CRPS. One ankle required fusion surgery (following subsidence of the talar component) with another one pending revision (ligament instability causing implant displacement). No patient had a symptomatic deep vein thrombosis or thromboembolic event. Our figures are comparable with other series. Our complication rate has not changed significantly over time. Our results, at present, suggest that most complications (98%) with the Mobility TAR can be satisfactorily managed without having a detrimental effect on the implant. There have been proven and promising results with total ankle replacement. However, there is a significant complication rate that must be made clear to the patient via informed consent; the rate still remains higher than for hip and knee arthroplasty

Introduction. We present a consecutive series of 19 patients with 22 intra-articular calcaneal fractures treated by percutaneous arthroscopic fixation (percutaneous arthroscopic calcaneal osteosynthesis “PACO”). Traditional open reduction and fixation regularly has significant wound complications. PACO has the advantage of direct visualization of the joint surface reduction with the benefit of minimal soft tissue trauma and wound complications. Methods. Between July 2010 & April 2012, 39 isolated closed intra-articular calcaneal fractures were admitted to St Mary's Hospital. All Sanders type 2 and type 3 fractures were included. Undisplaced fractures (13) were treated non-operatively and comminuted type 4 fractures (4) were treated with primary arthroscopic fusion. Surgery was performed on the next list with no delay for swelling. All patients had pre and post op CT scans. Patients were discharged in a temporary cast with routine follow up at 2, 6 and 12 weeks. Technique. Arthroscopy was performed in the lateral position with a 4.0mm arthroscope, using two sinus tarsi portals and a posterolateral portal. The fracture fragments were reduced percutaneously, held with wires before definitive fixation. Results. There were 10 three-part fractures (Sanders 3AB) and 12 two part (Sanders 2A/2B). Bohler's angle improved from 9.9 (7–18) to 27.7 (23–32) P <0.001. The mean time to surgery was 4 days (1–7), mean post-op stay was 1.9 days. Mean articular step of 0.9mm (0.4–1.9mm) on post-op CT. There were no deep wound infections. Conclusions. PACO is an accurate and reliable technique for fixation of calcaneal fractures, with a low complication rate, and minimal pre and post-operative delay
