Aims. No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Methods. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction. Results. Although four patients (12.5%) in the ELA groups and none in the STA group experienced complications, the difference was not statistically significant (p = 0.113). VAS and AOFAS score were significantly better in the STA group than in the ELA group at six months (p = 0.017 and p = 0.021), but not at 12 months (p = 0.096 and p = 0.200) after surgery. The operation time was significantly shorter in the STA group than in the ELA group (p < 0.001). The subtalar joint ROM was significantly better in the STA group (p = 0.015). Assessment of the amount of postoperative reduction compared with the uninjured limb showed significant restoration of calcaneal width in the ELA group compared with that in the STA group (p < 0.001). Conclusion. The ELA group showed higher frequency of wound complications than the STA group for Sanders type 2 calcaneal fractures even though this was not statistically significant.

Aims and objectives. The aim of this study was to statistically analyse the calcaneal fractures occurring in the community and distribution within the various age groups divided into decades. Methods and materials. Records of calcaneal fractures were retrieved from the audit department of the hospital using the various codes to identify patients reviewed in the clinics or admitted to the hospital between 1997 and 2009. The data collected included the total number of calcaneal fractures, total number in either gender, age at the time of incident, month of the year the incident occurred. Annual distribution of incidence of forearm fractures was calculated for every year and every month of the year. The age of the patients was divided into decades. Linear regression analysis and correlation coefficients were calculated between the incidence of fractures and different variables including age, gender and the time of the injury. Results. A total of 770 fractures were calculated including 511 males and 259 females (M/F=1.97). The average age of was 43.17 years (males=39.9 yrs, females=49.7 years). In both the sexes, there was a linear increase in the incidence of fractures in the first three decades of life with the rate of increase in males (R=0.999, r2=0.99) being 3 times that of females (R=0.96, r2=0.92). The incidence in females remained almost constant from 3rd decade to the 9th decade. The incidence in males reached a peak in the 3rd decade and then decreased steadily until the 10th decade. The incidence of fractures in females equalled that of males in the 8th decade; after which the incidence in males fell below females. There was a strong correlation between the increase in the incidence of fractures from February to August (R=0.9, r2=0.81) every year, after which the incidence reduced in the following months. There was a weak correlation between the increase in fractures from 1997 to 2009. Conclusion. There is a significant increase in the incidence of calcaneal fractures in the first three decades of life in both males and females. In males, the rate of increase in fractures is almost thrice than that of females. It can be said that men in their late twenties are more prone to sustain calcaneal fractures than any other age group or females. More injuries should be expected in August compared to the other months of the year. Further studies need to be done to look into the mechanism of injury. This could be helpful in prevention and reduction of the fracture incidence in the young and active age groups

Calcaneal fracture fixation over the past decade has been practised via an extensile lateral incision. This can be complicated by infection and wound breakdown. We have developed a new technique for fixation of the calcaneal fractures – MACO. We utilise a 4 cm sub fibular incision to aid joint visualisation and fracture reduction. Fixation is via percutaneous screws. We analysed our prospectively collected database. 26 fractures were fixed over an 18 month period at Glasgow Royal Infirmary by three consultant surgeons. 22 patients were male and half were smokers. Mean follow up was 5 months (range 1.5 – 18 months). The mean age of our patients is 41 (range 25–68). The mean pre operative Bohler's angle was 16.7 degrees. Gissane's angle was similarly abnormal with a mean of 129 degrees. The average duration of surgery was 73 minutes (range 45–100 minutes). Post operatively, Bohler's angle was improved. The mean was 29 degrees. There was no significant difference with Gissane's angle. The mean was 128 degrees. There were no superficial wound infections. One patient was troubled by wound breakdown with subsequent deep infection. There was no need for metalwork removal in our series of patients. Two patients developed post traumatic osteoarthritis of the sub talar joint. Only one has required sub talar joint fusion. We conclude that the novel technique which we describe is successful in restoring calcaneal anatomy with few complications. Further follow up is needed to determine the long term outcomes of such surgery

We have devised a new scoring system using visual analogue scales (VAS) to determine the functional outcome in 15 patients with 20 displaced intra-articular calcaneal fractures, confirmed by CT. The average follow-up was 19 months. A VAS was completed separately by the patient, the surgeon and an independent assessor. It showed satisfactory agreement between observers and strong correlations with a General Health Survey (SF36), a pain scale (McGill Pain Questionnaire) and a disease-specific, historical scale for calcaneal fractures (the Rowe score)

The late results of treatment of calcaneal fractures in 17 children (19 fractures) were reviewed at a mean of 16.8 years after injury. With the exception of one patient, all fractures had been treated conservatively. At follow-up there were few complaints. All but two patients had full or slightly reduced mobility of the subtalar joint and unrestricted foot function, including the ability to walk comfortably on uneven surfaces. Minor radiological abnormalities of the hindfoot were common; there were two cases of post-traumatic osteoarthritis. Clinical scoring of the ankle and hindfoot using the American Orthopaedic Foot and Ankle Society rating system averaged 96.2 points. The results suggest that up to 16.8 years after injury almost all children achieve excellent long-term functional results with conservative treatment of fractures of the os calcis. Open management may only be appropriate for adolescents with severe displacements

Aims. Complex joint fractures of the lower extremity are often accompanied by soft-tissue swelling and are associated with prolonged hospitalization and soft-tissue complications. The aim of the study was to evaluate the effect of vascular impulse technology (VIT) on soft-tissue conditioning in comparison with conventional elevation. Methods. A total of 100 patients were included in this prospective, randomized, controlled monocentre study allocated to the three subgroups of dislocated ankle fracture (n = 40), pilon fracture (n = 20), and intra-articular calcaneal fracture (n = 40). Patients were randomized to the two study groups in a 1:1 ratio. The effectiveness of VIT (intervention) compared with elevation (control) was analyzed separately for the whole study population and for the three subgroups. The primary endpoint was the time from admission until operability (in days). Results. The mean length of time until operability was 8.2 days (SD 3.0) in the intervention group and 10.2 days (SD 3.7) in the control group across all three fractures groups combined (p = 0.004). An analysis of the subgroups revealed that a significant reduction in the time to operability was achieved in two of the three: with 8.6 days (SD 2.2) versus 10.6 days (SD 3.6) in ankle fractures (p = 0.043), 9.8 days (SD 4.1) versus 12.5 days (SD 5.1) in pilon fractures (p = 0.205), and 7.0 days (SD 2.6) versus 8.4 days (SD 1.5) in calcaneal fractures (p = 0.043). A lower length of stay (p = 0.007), a reduction in pain (p. preop. = 0.05; p. discharge. < 0.001) and need for narcotics (p. preop. = 0.064; p. postop. = 0.072), an increased reduction in swelling (p < 0.001), and a lower revision rate (p = 0.044) could also be seen, and a trend towards fewer complications (p = 0.216) became apparent. Conclusion. Compared with elevation, VIT results in a significant reduction in the time to achieve operability in complex joint fractures of the lower limb.

Aims. We report the long-term outcomes of the UK Heel Fracture Trial (HeFT), a pragmatic, multicentre, two-arm, assessor-blinded, randomized controlled trial. Methods. HeFT recruited 151 patients aged over 16 years with closed displaced, intra-articular fractures of the calcaneus. Patients with significant deformity causing fibular impingement, peripheral vascular disease, or other significant limb injuries were excluded. Participants were randomly allocated to open reduction and internal fixation (ORIF) or nonoperative treatment. We report Kerr-Atkins scores, self-reported difficulty walking and fitting shoes, and additional surgical procedures at 36, 48, and 60 months. Results. Overall, 60-month outcome data were available for 118 patients (78%; 52 ORIF, 66 nonoperative). After 60 months, mean Kerr-Atkins scores were 79.2 (SD 21.5) for ORIF and 76.4 (SD 22.5) for nonoperative. Mixed effects regression analysis gave an estimated effect size of -0.14 points (95% confidence interval -8.87 to 8.59; p = 0.975) in favour of ORIF. There were no between group differences in difficulty walking (p = 0.175), or on the type of shoes worn (p = 0.432) at 60 months. Additional surgical procedures were conducted on ten participants allocated ORIF, compared to four in the nonoperative group (p = 0.043). Conclusion. ORIF of displaced intra-articular calcaneal fractures, not causing fibular impingement, showed no difference in outcomes at 60 months compared to nonoperative treatment, but with an increased risk of additional surgery.

Our study was undertaken to assess the inter- and intra-observer variability of the classification system of Sanders for calcaneal fractures. Five consultant orthopaedic surgeons with different subspecialty interests classified CT scans of 28 calcaneal fractures using this classification system. After six months, they reclassified the scans. Kappa statistics were used to analyse the two groups. The interobserver variability of the classification system was 0.32 (95% confidence interval (CI) 0.26 to 0.38). The subclasses were then combined and assessment of agreement between the general classes as a whole gave a kappa value of 0.33 (95% CI 0.25 to 0.41). The mean kappa value for intra-observer variability of the classification system was 0.42 (95% CI 0.22 to 0.62). When the subclasses were combined, it was 0.45 (95% CI 0.21 to 0.65). Our results show that, despite its popularity, the classification system of Sanders has only fair agreement among users

We have treated 14 patients (15 fractures) with nonunion of an intra-articular fracture of the body of the calcaneum. The mean follow-up was six years (2 to 8.5). A total of 14 fractures (93%) had initially been treated operatively with 12 (86%) having non-anatomical reductions. Four feet (27%) had concomitant osteomyelitis. Of the nonunions, 14 (93%) went on to eventual union after an average of two reconstructive procedures. All underwent bone grafting of the nonunion. The eventual outcome was a subtalar arthrodesis in ten (67%) cases, a triple arthrodesis in four (27%) and a nonunion in one (6%). Three patients had a wound dehiscence; all required a local rotation flap. The mean American Orthopaedic Foot and Ankle Society score at latest follow-up was 69, and the mean Visual analogue scale was 3. Of those who were initially employed, 82% (9 of 11) eventually returned to work. We present an algorithm for the treatment of calcaneal nonunion, and conclude that despite a relatively high rate of complication, this complex surgery has a high union rate and a good functional outcome

We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a superficial wound infection and five others eventually had a subtalar arthrodesis because of continuing pain. Restoration of Böhler’s angle was associated with a better outcome. The degree of arthritic change in the subtalar joint did not correlate with the outcome scores or Sanders’ classification. Prompt osteosynthesis should be considered for intra-articular fractures of the calcaneum in order to restore the shape of the hindfoot and Böhler’s angle

A minimally-invasive procedure using percutaneous reduction and external fixation can be carried out for Sanders’ type II, III and IV fractures of the os calcis. We have treated 54 consecutive closed displaced fractures of the calcaneum involving the articular surface in 52 patients with the Orthofix Calcaneal Mini-Fixator. Patients were followed up for a mean of 49 months (27 to 94) and assessed clinically with the Maryland Foot Score and radiologically with radiographs and CT scans, evaluated according to the Score Analysis of Verona. The clinical results at follow-up were excellent or good in 49 cases (90.7%), fair in two (3.7%) and poor in three (5.6%). The mean pre-operative Böhler’s angle was 6.98° (5.95° to 19.86°), whereas after surgery the mean value was 21.94° (12.58° to 31.30°) (p < 0.01). Excellent results on CT scanning were demonstrated in 24 cases (44.4%), good in 25 (46.3%), fair in three (5.6%) and poor in two (3.7%). Transient local osteoporosis was observed in ten patients (18.5%), superficial pin track infection in three (5.6%), and three patients (5.6%) showed thalamic displacement following unadvised early weight-bearing. The clinical results appear to be comparable with those obtainable with open reduction and internal fixation, with the advantages of reduced risk using a minimally-invasive technique

Aims

Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections.

We describe 24 fractures of the tuberosity of the calcaneus in 22 patients. Three were similar to the type of avulsion fracture which has been well-defined but the remainder represent a group which has been unrecognised previously. Using CT and operative findings we have defined the different patterns of fracture of the calcaneal tuberosity. Ten fractures extended into the subtalar joint, but did not fit the pattern of the common intra-articular fracture as described classically. We have defined a new pattern which consists of a fracture of the medial calcaneal process with a further fracture which separates the upper part of the tuberosity in the semicoronal plane. Non-operative treatment of displaced fractures resulted in a mis-shapen heel and a poor functional outcome. Open reduction and internal fixation with either a plate or compression screw did not give satisfactory fixation. We prefer to use an oblique lateral tension-band wire. This technique gave excellent fixation and we recommend it for the treatment of displaced fractures of the tuberosity of the calcaneus

Background:. In 1931, Gaenslen reported treatment of haematogenous calcaneal osteomyelitis through an incision on the sole of the heel, without the use of antibiotics. We have modified his approach to allow shorter healing times and early mobilisation in a modern series of cases. Method:. Sixteen patients with Cierny-Mader Stage IIIB chronic osteomyelitis were treated with split-heel incision, calcaneal osteotomy, radical excision, local antibiotics, direct skin closure and parenteral antibiotics. 4 patients had diabetic foot infection with neuropathy, 5 had infection after open injuries, 4 had haematogenous osteomyelitis and 3 had Grade 4 pressure ulceration with bone involvement. 14 had sinuses/ulcers and 12 had undergone previous surgery. Primary outcomes were eradication of infection, time to sinus/ulcer healing, mobility and need for modified shoes. Results:. Mean hospital stay was 19.2 days (7–44). 14 patients had no recurrence of infection at final follow-up (minimum 12 months; mean 53 months). Ulcers healed between 4 and 15 weeks. 2 patients with recurrent infection required amputation. Of the 14 salvaged patients, 10 mobilised unaided. 9 required modified shoes. Conclusion:. This protocol gave effective control of infection, ulcer healing and mobilisation within an acceptable time, but amputation remains a risk

Tibiotalocalcaneal (TTC) arthrodesis using a retrograde nail is a common salvage procedure for a range of indications. Previous work has suggested subtalar joint preparation is unnecessary to achieve satisfactory results. We examine the incidence of symptomatic subtalar nonunion following tibiotalocalcaneal fusion in a series of patients, all of whom had full preparation of the subtalar joint, and consider the possible contributing factors. We performed a retrospective review of all patients who underwent TTC arthrodesis from 2004–2010. All fusions were performed by the same surgeon with full preparation of both tibiotalar and subtalar joints. 61 TTC arthrodeses were performed in 55 patients (mean age = 59 years) using an intramedullary retrograde nail. Mean follow-up was 18 months (6–48 months). Fifty-six ankles (92%) achieved satisfactory union. Five patients (8%) had symptomatic non-union: 4 patients of the subtalar joint - with 3 patients undergoing revision subtalar arthrodesis and 1 patient of the tibiotalar joint. Nine patients required removal of the calcaneal screw (16%) – all had evidence of isolated subtalar nonunion prior to metalwork failure. Eight of these patients achieved asymptomatic union following screw removal. Subtalar nonunion following TTC fusion has resulted in recent changes to nail design to increase stability across the subtalar joint. Our results demonstrate a favourable overall nonunion rate with isolated subtalar nonunion making up the majority of cases. We also observed a significant rate of distal screw loosening, also associated with subtalar nonunion prior to screw removal, the significance of which merits further investigation

Background. Acquired flatfoot deformity goes ahead with a partial or complete rupture and thus insufficiency of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medial displacement calcaneal osteotomy to reconstruct the acquired deformity. Material & Methods. Twenty two patients (24 feet) with an average age of 58 (36–75) years were operated on for acquired flexible flatfoot deformity. Two patients had a bilateral procedure. Patients were seen pre-and postoperatively in order to evaluate following parameters: AOFAS hindfoot score, visual analogue scale for pain (0–10), the tarsometatarsal angle on lateral and ap standing x-rays, the cuneiform heights and talocalcaneal angle on lateral standing x-rays and subjective postoperative satisfaction score (1-worst to 5-best). Average time of follow-up was 24.7 months (12–48). Results. The AOFAS hindfoot score could be increased from 46.4 to 89.5 points, the visual analogue scale for pain decreased from 6.6 to 1.1. The average satisfaction score was 4.5 points with one patient scoring 2 and another one scoring 3. All the other patients scored either 4 or 5. All radiological parameters could be improved. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. The calcaneal screws had to be removed in 3 patients. Conclusion. Flexor digitorum longus transfer together with medial displacement calcaneal osteotomy gave satisfactory results for the treatment of acquired flatfoot deformity. All radiologic parameters were improved

Introduction. There is an ever increasing demand for Randomised Controlled Trials (RCTs) in Trauma and Orthopaedic Surgery. Patient recruitment is often challenging. Among other factors, individual surgeon's preference is often quoted as a major obstacle. Collective equipoise based on present or imminent controversy in the expert medical community has been proposed as a solution, but could not help in everyday running of a trial. We wanted to develop a new trial eligibility assessment tool using the Collective Equipoise Principle. Methods. We developed an online system that quantifies collective uncertainty among a group of surgeons for an individual clinical case in real time. This data was collected for patients in the UK Heel Fracture Trial (UK HeFT) as an independent research project. Both patients who agreed or not to take part in the trial were approached in six weeks follow up clinic to avoid interference with clinical course. For those who agreed, anonymous clinical data together with images (Xrays and CT) was published on a secure on line forum and registered surgeons were alerted via email and SMS. Surgeons submitted their opinion instantly via specially designed interactive voting scale. 80:20 ethical uncertainty distribution limit was applied using Subjective Logic to calculate an Uncertainty Index (UnIx) for every patient. This approach was evaluated as an eligibility assessment tool for RCTs. Results. 70 consecutive patients (77 calcaneal fractures) were assessed by a panel of 12 Consultant Trauma surgeons from hospitals acros the UK. All patients were eligible for the UK HeFT according to standard eligibility criteria approach. UnIx demonstrated reliable correlation with level of uncertainty and confidence about treatment choice expressed by surgeons. The panel was certain about treatment for 9 (13%) patients. The assesment results were available within 48 hours from a case submission to the panel. Discussion and Conclusion. UnIx is an effective and ethical eligibility assessment tool based on surgeon's opinion. It can be calculated for every patient in Randomised Controlled Trials. This protects patients when there is no controversy about treatment choice. UnIx can potentially increase patient recruitment by including more patients for eligibility assessment and more sceptical surgeons in clinical trials. Patient's perception that his/her condition was assessed by surgical panel may also be important

Aims

The aim of this study was to develop a psychometrically sound measure of recovery for use in patients who have suffered an open tibial fracture.

We reviewed 59 bone graft substitutes marketed by 17 companies currently available for implantation in the United Kingdom, with the aim of assessing the peer-reviewed literature to facilitate informed decision-making regarding their use in clinical practice. After critical analysis of the literature, only 22 products (37%) had any clinical data. Norian SRS (Synthes), Vitoss (Orthovita), Cortoss (Orthovita) and Alpha-BSM (Etex) had Level I evidence. We question the need for so many different products, especially with limited published clinical evidence for their efficacy, and conclude that there is a considerable need for further prospective randomised trials to facilitate informed decision-making with regard to the use of current and future bone graft substitutes in clinical practice.

The treatment of infected exposed implants which have been used for internal fixation usually involves debridement and removal of the implant. This can result in an unstable fracture or spinal column. Muscle flaps may be used to salvage these implants since they provide soft-tissue cover and fresh vascularity. However, there have been few reports concerning their use and these have concentrated on the eradication of the infection and successful soft-tissue cover as the endpoint. There is no information on the factors which may influence the successful salvage of the implant using muscle flaps.

We studied the results and factors affecting outcome in nine pedicled muscle flaps used in the treatment of exposed metal internal fixation with salvage of the implant as the primary endpoint. This was achieved in four cases. Factors predicting success were age < 30 years, the absence of comorbid conditions and a favourable microbiological profile. The growth of multiple organisms, a history of smoking and the presence of methicillin-resistant Staphylococcus aureus on wound cultures indicated a poor outcome. The use of antibiotic beads, vacuum-assisted closure and dressing, the surgical site, the type of flap performed and the time from primary surgery to flap cover were not predictive of outcome.
