Aims. This paper documents the epidemiology of adults (aged more than 18 years) with a calcaneal fracture who have been admitted to hospital in England since 2000. Secondary aims were to document whether publication of the United Kingdom Heel Fracture Trial (UK HeFT) influenced the proportion of patients admitted to hospital with a calcaneal fracture who underwent surgical treatment, and to determine whether there has been any recent change in the surgical technique used for these injuries. Patients and Methods. In England, the Hospital Episode Statistics (HES) data are recorded annually. Between 2000/01 and 2016/17, the number of adults admitted to an English NHS hospital with a calcaneal fracture and whether they underwent surgical treatment was determined. Results. During this 17-year period, 62 858 patients were admitted to hospital with a calcaneal fracture. The male-to-female ratio was 2.66:1. The mean annual incidence was 10.5/100 000 for men and 3.8/100 000 for women. The results of the UK HeFT were published in July 2014. The percentage of patients admitted with a calcaneal fracture undergoing internal fixation was 7.31% (3792/51 859) before and 7.38% (534/7229) after its publication. This difference was not statistically significant (p = 0.94). Since 2015, there has been a significant increase in the percentage of calcaneal fractures treated by closed reduction and internal fixation, as opposed to open reduction and internal fixation, from 7.7% (292/3792) to 13.29% (71/534) (p < 0.001). Conclusion. This study documents the epidemiology and trends in surgical treatment of calcaneal fractures in England. We established that surgeons did not change their practice in terms of offering surgery to these patients in response to the results of the UK HeFT. There has been a significant (p < 0.001) increase in the number of calcaneal fractures being treated surgically using less invasive procedures

Objectives. The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Methods. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared. Results. The relative displacement of the EFLIF was less than that of the plate (0.1363 mm to 0.1808 mm). The highest von Mises stress value on the plate was 33% higher than that on the EFLIF. A normal restoration of the Böhler angle was achieved in both groups. No significant difference was found in the clinical outcome on the American Orthopedic Foot and Ankle Society Ankle Hindfoot Scale, or on the Visual Analogue Scale between the two groups (p > 0.05). Wound complications were more common in those who were treated with ORIF (p = 0.028). Conclusions. Both EFLIF and ORIF systems were tested to 160 N without failure, showing the new construct to be mechanically safe to use. Both EFLIF and ORIF could be effective in treating Sanders type 2 calcaneal fractures. The EFLIF may be superior to ORIF in achieving biomechanical stability and less blood loss, shorter surgical time and hospital stay, and fewer wound complications. Cite this article: M. Pan, L.

In this paper, we critically appraise the recent publication of the United Kingdom Heel Fracture Trial, which concluded that when patients with an absolute indication for surgery were excluded, there was no advantage of surgical over non-surgical treatment in the management of calcaneal fractures. We believe that selection bias in that study did not permit the authors to reach a firm conclusion that surgery was not justified for most intra-articular calcaneal fractures.

Aims. Management of intra-articular calcaneal fractures remains a debated topic in orthopaedics, with operative fixation often held in reserve due to concerns regarding perioperative morbidity and potential complications. The purpose of this study was to identify the characteristics of patients who developed surgical complications to inform the future stratification of patients best suited to operative treatment for intra-articular calcaneal fractures and those in whom surgery was highly likely to produce an equivocal functional outcome with potential post-operative complications. Methods. All patients who underwent open reduction and internal fixation of calcaneal fractures utilizing the Sinus Tarsi approach between March 2014 and July 2018 were identified using theatre records. Patient imaging was used to assess pre- and post-operative fracture geometry with Computed Tomography (CT) used for pre-operative planning. Each patient's clinical presentation was established through retrospective analysis of medical records. Patients provided verbal consent to participation and patient reported outcome measures were recorded using the Maryland Foot Score. Results. Fifty-eight intra-articular calcaneal fractures (fifty-three patients including five bilateral, mean age = 46.91 years) were included. Forty-nine patients were injured as a result of a fall from a height (92.4%). Mean time from presentation to surgery was 3.23 days (range 0–21). Mean Maryland Foot score was found to be 77.6 (+/− 16.22) in forty-five patients. Five patients (9.4%) had wound complications; two superficial (3.7%) and three deep (5.6%). Conclusion. Intra-articular fractures of the calcaneus should be considered for surgical intervention in order to improve long-term functional outcomes. The Sinus Tarsi approach provides the potential to decrease the operative complication rate whilst maintaining adequate fixation, however, the decision to surgically manage these fractures should be carefully balanced against the risk of post-operative complications. This increased risk of complication associated with smoking may tip the balance against benefit from surgical management

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.

Three dimensional printing is an emerging new technology in medicine and the current educational value of 3D printed fracture models is unknown. The delayed surgery and need for CT imaging make calcaneal fractures an ideal scenario for preoperative 3D printed (3Dp) fracture models. The goal of this study is to assess if improvements in fracture understanding and surgical planning can be realized by trainees when they are given standard CT imaging and a 3Dp model compared to standard CT imaging and a virtual 3D rendering (3D CT). Ethics approval was granted for a selection of calcaneal fracture imaging studies to be collected through a practice audit of a senior orthopaedic trauma surgeon. 3Dp models were created in house. Digital Imaging and Communications in Medicine (DICOM) files of patient CT scans were obtained from local servers in an anonymized fashion. DICOM files were then converted to .STL models using the Mimics inPrint 2.0 (Materialise NV, Leuven, Belgium) software. Models were converted into a .gcode file through a slicer program (Simplify3D, Blue Ash, OH USA). The .gcode files were printed on a TEVO Little Monster Delta FDM printer (TEVO USA, CO USA) using 1.75mm polylactic acid (PLA) filament. Study participants rotated through 10 workstations viewing CT images and either a digital 3D volume rendering or 3Dp model of the fractured calcaneus. A questionnaire at each workstation assessed fracture classification, proposed method of treatment, confidence with fracture understanding and satisfaction with the accuracy of the 3Dp model or 3D volume rendering. Participants included current orthopaedic surgery trainees and staff surgeons. A total of 16 residents and five staff completed the study. Ten fracture cases were included in the analysis for time, confidence of fracture understanding, perceived model accuracy and treatment method. Eight fracture cases were included for assessment of diagnosis. There were no cases that obtained universal agreement on either Sanders classification or treatment method from staff participants. Residents in their final year of studies had the quickest mean time of assessment (60 +/− 24 sec.) and highest percentage of correct diagnoses (83%) although these did not reach significance compared to the other residency years. There was a significant increase in confidence of fracture understanding with increasing residency year. Also, confidence was improved in cases where a 3Dp model was available compared to conventional CT alone although this improvement diminished with increasing residency year. Perceived accuracy of the cases with 3Dp models was significantly higher than cases without models (7 vs 5.5 p < 0.0001). This is the first study to our knowledge to assess trainee confidence as a primary outcome in the assessment of the educational value of 3Dp models. This study was able to show that a 3Dp model aides in the perceived accuracy of fracture assessment and showed an improvement in trainee confidence, although the effect on confidence seems to diminish with increasing residency year. We propose that 3D printed calcaneal fracture models are a beneficial educational tool for junior level trainees and the role of 3Dp models for other complex orthopaedic presentations should be explored

Introduction:. Although dislocation of the peroneal tendons (PT's) in association with calcaneal fractures has been described over 25 years ago, it frequently passes unrecognised by radiologists and orthopaedic surgeons. This retrospective study aims to determine the prevalence of PT dislocation in association with calcaneal fractures at a single institution and describe systematic steps to avoid missed diagnosis at each stage of management. Methods:. CT scans of all patients with calcaneal fractures from the Picture Archiving and Communications System (PACS) from 2010 were systematically reviewed. The senior author and a Musculoskeletal Radiologist analysed the images for concomitant dislocation or subluxation of the PT's, utilizing criteria as defined by Ho et al. Further to this we included patients who sustained calcaneal fractures with associated PT dislocation prior to June 2010 and were referred either for primary open reduction or later with post-traumatic osteoarthrosis of the subtalar joint. Results:. Over three years and nine months beginning in June 2010, 71 calcaneal fractures were identified on PACS. 15 of those had associated subluxation or dislocation of the peroneal tendons either on CT scan or at surgery (21%). 10 of our 71 patients exhibited a fleck sign on plain anteroposterior ankle x-ray (14.1%) suggesting potential avulsion of the superior peroneal retinaculum. The combined cohort comprised 28 patients, 23 men and 5 women, aged 21 to 82 years (average, 46.3 years). 22 (79%) of PT dislocations were not recognised at the original injury. In six patients undergoing operative fixation, five (83.3%) had dislocated PT's noted on CT scan. In one case (16.7%) the peroneal tendons were clinically dislocated. Conclusion:. The PT dislocation rate in this paper is comparable with the literature. Patients should undergo careful clinical examination, radiological assessment with x-ray and CT followed by probing at surgery to ensure the diagnosis is not missed

Purpose of the study: is to evaluate the wound healing problems following. Open reduction and internal fixation (ORIF) of calcaneal fractures. Introduction: Calcaneal fracture is challenging to all orthopaedic surgeons. It can be disabling injury with economical consequences, particularly it usually happen in men workers. ORIF is often needed to improve the final outcome of these difficult injuries. However, without careful selection of patients, time of surgery and using meticulous surgical technique, wound breakdown (the most frequent complication) can be disastrous. Material and Method: We reviewed 45 consecutive series calcaneal fractures treated by O.R.I.F. between 1996 and 2001. The mean age was 36 years (range 18 to 57) All but one fracture resulted from a fall from height. Cases were analyzed to ascertain the mechanism of injury, associated injuries, presence of medical problems e.g. Diabetes or peripheral vascular disease, smoking. Number of days elapsed before surgery, method of wound closure, and the use of drain and Saunders grade. Results: All patients were Saunders grade two& three in our study. Fourteen were smokers. No one with peripheral vascular compromise, Body mass Index was within normal limit in all of them. Average time elapsed before surgery was 8 days. All operations were done by one surgeon, who closed all wounds in layers and regularly used a drain. We had four (11%) delayed healing (more than 2 weeks). No serious wound problems needing free flaps or amputation. Conclusion: ORIF for certain calcaneal fractures greatly improve the outcome of these unpleasant injuries. Appropriate patient selection and adherence to meticulous surgical technique significantly reduces wound healing problems

Persistent pain is a common cause of disability in patients after fractures of the calcaneum. Amongst the possible causes for post traumatic pain is the development of degenerative osteoarthritis of the posterior facet of the subtalar joint. However there are many other causes of post-traumatic hindfoot pain which require consideration prior to treatment. Knowledge of the patho-anatomy of calcaneal fractures is required to reach an accurate diagnosis. Significant symptoms and disability may be treated by arthrodesis of the subtalar joint. Post-traumatic arthritis in the non-operatively treated calcaneal fracture is however usually associated with deformity of the hindfoot, disordered hindfoot biomechanics, lateral wall fibular impingement and fibular tendon dysfunction. Fractures treated by primary open reduction and fixation should be well aligned but despite anatomic reduction may also develop posterior facet arthritis. Symptoms may also be caused by prominence or impingement of the implant, particularly of locked perimeter plates on the lateral wall. Patients therefore require careful assessment prior to surgery and any operative measures have to address these key features in order to produce a satisfactory clinical result. This lecture will address the potential problems of this type of surgery and key features in the clinical assessment and imaging of these patients. Subtalar arthrodesis in the presence of deformity is technically complex and requires careful planning in order to correct the deformity and to produce a well aligned hindfoot to allow corrected biomechanics without impingement and the fitment of suitable footwear. The surgical techniques and different types of surgery required to adequately manage the posterior facet and deformity will be covered and will include arthroscopically assisted in-situ fusion, the safe approaches for open surgery and techniques to reconstruct the lateral wall, fibular tendon function and osteotomies required to restore calcaneal height and alignment

This is a case series report on the outcomes of patients that have received ORIF of their calcaneal fractures at Craigavon Hospital, Northern Ireland, for the first 2 years since it opened. It is a one surgeon series. Methods. Patients were identified from the theatre logbook. The patient recalled to clinic for interview and examination. Outcome was assessed using The Ankle-Hindfoot Scale devised by the American Orthopaedic Foot and Ankle Society. This was recorded with data for the patient's notes and CT scans. These data included age, date of surgery, mechanism of injury, associated injuries and previous function. The calcaneal fractures were classified according to the Sanders Classification. Results. Sixteen patients identified from the theatre register. Of these patients, 10 patients were contactable and attended for evaluation. The data from these 10 patients was then analysed. There 9 male patients and one female. Time from operation from 9.5 months to 33 months. All patients had fractures classified as Sanders Type IV. All implants were Variax calcaneal plates. One patient had metalwork removed at 15 months. All patients had commenced weightbearing at 3 months. Outcome scores ranged from 52–97 (mean 78.3, median 79). Six of the ten had returned to work at this review. Subtalar motion was universally affected. Discussion. This one surgeon case series reflects the current literature on calcaneal fractures, in that there is a variation in outcome which is multifactorial. There is also a difficulty in defining a classification system which can reflect outcome. The results of this series suggest that there is a trend of improving outcome scores as time from injury progresses, and that outcome score tends to decrease as age at injury increases

Between 2000 and 2004 we used subtalar arthrodesis to treat 44 patients for continued pain after intra-articular calcaneal fracture. All the fractures were due to laboral accidents. Average time to union was 3 month(2 to 4 months). Complications were minor in 12 patients and major in 10 patients. Lenght of follow-up was 23 months. Hindfoot scores (clinical rating system of the American Orthopaedic Foot and Ankle Society)improved from 35,11 to 67,22. The results were excelent in 7 patients, good in 24, fair in 7 and bad in 6 patients. Return to previous activities was possible in 26 pacients. We concludes that subtalar arthrodesis represents a rather effective treatment of the subtalar arthritis due to inta-articular calcaneal fractures. The majority of patients can have improvement with surgical reconstruction but pain relief is usually not complete

Background: Closed reduction of intra-articular calcaneal fractures sometimes lack the accuracy desired for restoring the normal anatomy of the articular surface of the calcaneus. In this study, we evaluate the preliminary results of closed reduction of the intra-articular calcaneal fractures with an Ilizarov frame. Patients and Method: Forty patients (25 males and 15 females) with 50 intra-articular fracture calcaneal fractures were treated with closed reduction and an Ilizarov frame. The mean age was 25.4 years (range from 19 to 65). Union was achieved after two months. The results were evaluated on the basis of combined clinical and radiological examination at the latest follow-up. Results were classified according to the protocol and scoring system used by Paley and Hall 1993. Results: The mean follow up period was 1.9 years (range 6 months to 4 years). At final follow up there were 15 excellent feet, 26 were good, 6 fair and 3 poor. The mean Bohler angle postoperatively was 260 (range 17 to 35). Superficial infection occurred in seven feet and was controlled. Skin pressure necrosis of the posterior aspect of the heel occurred in three feet. One needed a skin graft. Conclusion: This method is a minimally invasive technique. The technique has the ability to restore the normal anatomy, shape and length of the calcaneal body, especially in Sander’s type III and type IV fractures. It is particularly useful for osteoprotic bone as it provides rigid fixation

Aim. The optimal treatment of displaced intra-articular calcaneal fractures (DIACF) remains controversial. The operative treatment group has better anatomical recovery, functional outcome scores and less pain than non operative treatment patients, but it may lead to a higher incidence of complications, such as delayed wound healing and surgical site infections. The aim of this study was to analyze the prophylactic effect using a biphasic bone substitute (BS) eluting antibiotic on calcaneal implant-related infections. Methods. We conducted a retrospective non-randomized review of all patients with DIACF (type Sanders 2, 3, 4) from 2009 to 2017; 103 calcaneal fractures of 90 patients (13 bilaterally) were treated with plates. All cases received the same systemic antibiotic prophylaxis; BS was used on more complex cases with large bone defect and BS was added with antibiotic on higher risk patients. We collected data including complications: major (deep infections, osteomyelitis) and minor complications (wound dehiscence, superficial infection). We considered the absence of deep infections after 6 months. We compared statistically the outcomes of 3 operative groups: the first was treated with plates only (A), the second with plates and BS (B) and the third with plates added with BS eluting antibiotic (vancomicine or gentamicine) (C). Results. We examined 99 cases (group A: n33, B: n52, C: n14), 4 patients were lost; the mean age was 47,8 years (range 18–83 years). Minimal follow up was 6 months (range: 6 – 42 months). We have observed 8 (8,1%) implant-related infection (A:4, 12,1%; B:4, 7,7%), 2 (2%) superficial infection (B:2, 3,8%), 20 (20,2%) wound healing defects (A:11, 33,3%; B:7, 13,5%; C:2, 14,2%). We found a relevant reduction of the rates in the group C regarding the major complications without a statistic evidence. Conclusion. The three groups are uneven; particularly the group C has a high concentration of more severe risk patients. The low number of cases in the group C, which limited the statistic evidence, represents a second limit. The absence of major infection on group C found in this study, needs larger data to confirm this result. The open surgery has an intrinsic rate of skin complications but the use of BS eluting local antibiotic is an additional tool to manage difficult complex fractures and to prevent implanted-related infection, inhibiting bacterial colonization and biofilm protection, particularly in those patients that have suffered from a minor complication, which could lead to a deep infection

We present a novel approach to the management of patients with longstanding heel ulcers complicated by open calcaneal fractures. The principles of management of diabetic foot ulcers were combined with applied physiology of fracture healing. Case notes of 6 consecutive patients who presented to our diabetic foot clinic between January 2009 and December 2009 were reviewed. Type of diabetes, duration of heel ulcer, type of fracture and treatment given were recorded. Initial treatment consisted of regular local debridement and application of dressing. Vacuum Assisted Continuous (VAC) pump application was deferred until 6 weeks to preserve fracture hematoma and thereby initiate fracture healing. In all patients, VAC pump was started at 6 weeks and continued till healing of ulcer to adequate depth. Infection was treated aggressively with appropriate antibiotics according to the microbiology results. The average age was 53 (40-60) and the mean duration of follow up was 6 months. All wound healed completely, fractures united and patients returned to previous function. An open calcaneal fracture presents a severe injury likely to be complicated by infection and consequent osteomyelitis leading to amputations. In our group of patients, a novel treatment approach consisting of multidisciplinary model resulted in successful limb preservation and return to function

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

Different calcaneal plates with locked screws were compared in an experimental model of a calcaneal fracture. Four plate models were tested, three with uniaxially-locked screws (Synthes, Newdeal, Darco), and one with polyaxially-locked screws (90° ± 15°) (Rimbus). Synthetic calcanei were osteotomised to create a fracture model and then fixed with the plates and screws. Seven specimens for each plate model were subjected to cyclic loading (preload 20 N, 1000 cycles at 800 N, 0.75 mm/s), and load to failure (0.75 mm/s). During cyclic loading, the plate with polyaxially-locked screws (Rimbus) showed significantly lower displacement in the primary loading direction than the plates with uniaxially-locked screws (mean values of maximum displacement during cyclic loading: Rimbus, 3.13 mm (. sd. 0.68); Synthes, 3.46 mm (. sd. 1.25); Darco, 4.48 mm (. sd. 3.17); Newdeal, 5.02 mm (. sd. 3.79); one-way analysis of variance, p < 0.001). The increased stability of a plate with polyaxially-locked screws demonstrated during cyclic loading compared with plates with uniaxially-locked screws may be beneficial for clinical use

Materials & Methods: A retrospective study. 25 cases of fracture Calcaneum during April 2001–2004 were reviewed for their clinical outcome. Aim of the study: To assess the clinical and functional outcome of the Management of Intra and Extra articular Calcaneal fractures in district general hospital. Results: 22 male and 3 female. Intraarticular fractures 15 (60%)of which 10 were displaced and 5 undisplaced. Extraarticular were 10 (40%) of which displaced and undisplaced were 5 each. Fall from height was seen in 20 (80%)patients. Associated injuries was seen in 10(40%) patients of which 8(32%) of them had fracture spine. All the cases of intaarticular fractures had C.T. scan. 5 cases had MUA and pinning for the extraarticular fracture. 8(32%) displaced intraarticular fractures underwent ORIF. 2((8%) intraarticular displaced fractures were treated conservatively. The average follow-up one-year. The final outcome assessed clinical and radiologically. 2 cases of infection, 4 cases of stiffness, 2 cases of deformity seen.1 case had parasthesia. The final outcome all the fractures treated conservatively were good. Fractures underwent ORIF had better outcome and more complication rate as compared to conservative treatment. Conclusion: Commonest mode of injury is fall from height and associated injury incidence is usually high. Even the undisplaced intraarticular fractures of calcaneum do develop residual stiffness and difficulty in walking on uneven ground. Displaced fractures needs fixation for better results and facilitation for secondary operations. Wound infection, stiffness and deformity are known complications. In this small audit all three group did develop stiffness and we recommend a bigger, independent audit

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.

Thirty-six patients with 39 fresh fractures of the calcaneus were investigated by standard radiography and by computerised tomography. It was found that the size and disposition of the fracture fragments and the degree of involvement of the posterior facet of the subtalar joint were more clearly shown by CT scanning. We recommend this technique for assessment and particularly for pre-operative planning.

Open reduction and internal fixation for displaced intra-articular fractures of the calcaneum has become an established method of treatment. A recent randomised, controlled trial has questioned the benefits of surgery, in particular, pain relief. We reviewed the cases undertaken in our department, complications, which have arisen, and their treatment. We have devised a management plan in conjunction with the department of plastic surgery to minimise the effect of these complications. There were 124 procedures carried out over a 12 years period, 116 unilateral and 4 bilateral in 120 patients (106 males and 14 females, age range [18 to 66]). Two further patients were included who had had surgery in another hospital and had been referred to our plastic surgery unit with significant wound complications. The patients were retrospectively assessed with a case note review and an updated clinical evaluation. The assessment focussed particularly on wound complications including breakdown classified as either major or minor, and association with infection, haematoma and drainage. Neurological symptoms were also noted. There were five major wound complications, three from our unit and two from another hospital. Infection was present in three cases. Four healed uneventfully but one of the infected group subsequently had a below knee amputation for refractory infection. Minor wound breakdown was more common. There was no association with haematoma or drainage but wound breakdown occurred more frequently in patients who smoked. Neurological complications were infrequent and temporary. In conclusion this study confirmed that there is a significant morbidity associated with the surgical management of these fractures, although, the vast majority of patients’ wounds healed uneventfully. With a sensible management plan, which involves working in conjunction with plastic surgeons, even major soft tissue complications may be addressed.

Background Open reduction and internal fixation for displaced intra-articular fractures of the calcaneum has become an established method of treatment. A recent randomised, controlled trial has questioned the benefits of surgery, in particular, pain relief.

Method We reviewed the cases undertaken in our department, complications which have arisen, and their treatment. We have devised a management plan in conjunction with the department of plastic surgery to minimise the effect of these complications. There were 124 procedures carried out over a 12-year period, 116 unilateral and 4 bilateral in 120 patients (106 males and 14 females, age range 18–66). Two further patients were included who had had surgery in another hospital and had been referred to our plastic surgery unit with significant wound complications.

The patients were retrospectively assessed with a case note review and an updated clinical evaluation. The assessment focussed particularly on wound complications including breakdown classified as either major or minor, and association with infection, haematoma and drainage. Neurological symptoms were also noted.

Results There were five major wound complications, three from our unit and two from another hospital. Infection was present in three cases. Four healed uneventfully but one of the infected group subsequently had a below knee amputation for refractory infection. Minor wound breakdown was more common. There was no association with haematoma or drainage but wound breakdown occurred more frequently in patients who smoked. Neurological complications were infrequent and temporary.

Conclusion This study confirmed that there is a significant morbidity associated with the surgical management of these fractures, although the vast majority of patients’ wounds healed uneventfully. With a sensible management plan, which involves working in conjunction with plastic surgeons, even major soft tissue complications may be addressed.

Background. Traditionally, the extended lateral approach (ELA) was the favoured approch for calcaneal fractures, but has been reported to have high incidence of wound complications. There has been a move amongst surgeons in the United Kingdom towards the sinus tarsi approach (STA) due to its minimally invasive nature, attempting to reduce such complications. Aims. To evaluate outcomes of ELA and STA for all consecutive calcaneal fracture fixation in our institution over a 10yr period. Method. Retrospective cohort study of all calcaneal fractures surgically treated with either approach between January 2008 and January 2018. Anatomic restoration was assessed radiologically by the change in Gissane's and Bohler's angles and calcaneal width. Post-operative complications including metalwork removal were recorded. Results. 35 calcaneal fractures were managed surgically via either approach during this period (21 STA and 14 ELA). There was a statistically significant improvement in the radiological makers when the post-operative films were compared to pre-operative ones. When the post-operative films from the 2 groups were compared against each other, there was no significant difference (p< 0.05) in any of the radiological markers. In the ELA group, 2 patients (14.3%) developed deep infections requiring metalwork removal and 1 had delayed wound healing (7.1%). No deep infections occurred with the STA; 1 patient (4.8%) had a superficial infection, treated with antibiotics. Of patients who had metalwork in situ for more than 1 year, 37.5% of the STA group required removal due to pain compared to only 16.7% with ELA. Conclusions. We have moved from ELA to STA. Our results have shown no difference in restoration of calcaneal anatomy but with a decrease in post-operative wound complications including infection. However, we have shown an increase in metalware removal in the STA group and it is important to ascertain the cause and significance of this

To identify the demographics, mechanisms of injury and treatment modalities of patients presenting at CHBAH with calcaneal fractures. A retrospective study of all admitted patients with calcaneal fractures from 01 January 2018 to 31 December 2022. The data collected includes age, gender, side of injury, mechanism of injury, isolated injury versus polytrauma, open and close fractures, different treatment modalities and time to surgery. The descriptive data will be analysed, with results presented as frequency charts, histograms, and percentages. A total of 98 patients showed a male predominance of 90.8% compared to 9.2% of females. The median age was 38 years, the commonest mechanism was from falls from height, accounting for 67.3% with gunshot injuries accounting for 5%. Bilateral fractures were observed in 5 patients, with similar total numbers between those isolated to the left (47) as compared to the injuries isolated to the right side (46). Calcaneus fractures associated with other injuries in polytrauma cases were observed in 17.4%, and open fractures were observed in 7 patients with 5 having occurred post gunshot injury. A total of 48 patient required surgical treatment with the average time to surgery found to be 15 days. The surgical management varied, with open reduction and internal fixation with plate and screws in 68.7%, followed by 16.7% of patients who were treated with open reduction and internal screw fixation. Calcaneal fractures occurred frequently amongst male patients secondary to fall from height. Half of the total patient number admitted had require a surgical intervention to treat the fracture, with open reduction and internal fixation with plate and screws being the frequent mode of fixation in this population group

Background. Optimal management of displaced intra-articular calcaneal fractures remains controversial. The aim of this prospective cohort study was to compare the clinical and radiological outcomes of minimally invasive surgery (MIS) versus non-operative treatment in displaced intra-articular calcaneal fracture up to 2-years. Methods. All displaced intra-articular calcaneal fractures between August 2014 and January 2019 that presented to a level 1 trauma centre were considered for inclusion. The decision to treat was made by a multidisciplinary meeting. Operative treatment protocol involved sinus tarsi approach or percutaneous reduction & internal fixation. Non-operative protocol involved symptomatic management with no attempt at closed reduction. All fractures were classified, and the MOXFQ/EQ-5D-5L scores were used to assess foot and ankle and general health-related quality of life outcomes respectively. Results. 101 patients were recruited at a level 1 major trauma centre, between August 2014 and January 2019. Our propensity score matched 44 patients in the surgical cohort to 44 patients in the non-surgical cohort. At 24 months, there was no significant difference in the MOXFQ Index score (p<0.05) however the patients in the surgical cohort had a significantly higher EQ-5D-5L Index score (p<0.05). There was also a higher return to work (91% vs 72%, p<0.05) and physical activity rate (46 vs. 35%, p<0.05) in the surgical cohort despite a higher proportion of more complex fractures in the surgical cohort. The wound complication rate following surgery was 16%. 14% of patients in the non-operative cohort subsequently underwent arthrodesis compared to none of the patients in the surgical cohort. Conclusion. In this study, we found operative treatments were associated with low rates of surgical complication at 2-years and long term pain improvement, facilitating earlier and better functional outcomes for complex injury patterns compared to nonoperative treatment

The February 2023 Foot & Ankle Roundup. 360. looks at: Joint inflammatory response in ankle and pilon fractures; Tibiotalocalcaneal fusion with a custom cage; Topical application of tranexamic acid can reduce blood loss in calcaneal fractures; Risk factors for failure of total ankle arthroplasty; Pain catastrophizing: the same as pain forecasting?

This edition of the Cochrane Corner looks at the three reviews that were published in the second half of 2023: surgical versus non-surgical interventions for displaced intra-articular calcaneal fractures; cryotherapy following total knee arthroplasty; and physical activity and education about physical activity for chronic musculoskeletal pain in children and adolescents

Treatment of comminuted intraarticular calcaneal fractures remains controversial and challenging. Anatomic reduction with stable fixation has demonstrated better outcomes than nonoperative treatment of displaced intraarticular fractures involving the posterior facet and anterior calcaneocuboid joint (CCJ) articulating surface of the calcaneus. The aim of this study was to investigate the biomechanical performance of three different methods for fixation of comminuted intraarticular calcaneal fractures. Comminuted calcaneal fractures, including Sanders III-AB fracture of the posterior facet and Kinner II-B fracture of the CCJ articulating calcaneal surface, were simulated in 18 fresh-frozen human cadaveric lower legs by means of osteotomies. The ankle joint, medial soft tissues and midtarsal bones along with the ligaments were preserved. The specimens were randomized according to their bone mineral density to 3 groups for fixation with either (1) 2.7 mm variable-angle locking anterolateral calcaneal plate in combination with one 4.5 mm and one 6.5 mm cannulated screw (Group 1), (2) 2.7 mm variable-angle locking lateral calcaneal plate (Group 2), or (3) interlocking calcaneal nail with 3.5 mm screws in combination with 3 separate 4.0 mm cannulated screws (Group 3). All specimens were biomechanically tested until failure under axial loading with the foot in simulated midstance position. Each test commenced with an initial quasi-static compression ramp from 50 N to 200 N, followed by progressively increasing cyclic loading at 2Hz. Starting from 200 N, the peak load of each cycle increased at a rate of 0.2 N/cycle. Interfragmentary movements were captured by means of optical motion tracking. In addition, mediolateral X-rays were taken every 250 cycles with a triggered C-arm. Varus deformation between the tuber calcanei and lateral calcaneal fragments, plantar gapping between the anterior process and tuber fragments, displacement at the plantar aspect of the CCJ articular calcaneal surface, and Böhler angle were evaluated. Varus deformation of 10° was reached at significantly lower number of cycles in Group 2 compared to Group 1 and Group 3 (P ≤ 0.017). Both cycles to 10° plantar gapping and 2 mm displacement at the CCJ articular calcaneal surface revealed no significant differences between the groups (P ≥ 0.773). Böhler angle after 5000 cycles (1200 N peak load) had significantly bigger decrease in Group 2 compared to both other groups (P ≤ 0.020). From biomechanical perspective, treatment of comminuted intraarticular calcaneal fractures using variable-angle locked plate with additional longitudinal screws or interlocked nail in combination with separate transversal screws seems to provide superior stability as opposed to variable-angle locked plating only

Introduction. Intraarticular calcaneal fractures often need open reduction and internal fixation (ORIF) with plate osteosynthesis. The wound complication is one of the common problems encountered following this and affects the outcome adversely. Our study was done to assess how far postoperative slab/cast can avert wound complications. Methods. Out of 42 patients with unilateral intraarticular calcaneal fractures, 20 were offered postoperative slab/cast and this was continued for six weeks. The remaining 22 patients were not offered any plaster. All patients were followed-up for two years. Results. The incidence of wound dehiscence was 2 in the plaster group as well as 8 in the non-plaster group and this was statistically significant (p = 0.02). Also, significantly lower heel widening was reported in the plaster group (p = 0.03). Although, there was no significant difference in the patient-reported outcome (Maryland Foot Score) and the incidence of pain between the two groups, the occurrence of neurological deficit following surgery and the postoperative range of movements were comparable in these two groups. Conclusion. Thus, it may be concluded that postoperative plaster application for the initial six weeks could be a low-cost yet effective way to reduce wound complications following plate osteosynthesis in intraarticular calcaneal fractures

Displaced intraarticular calcaneal fractures are debilitating injuries with significant socioeconomic and psychological effects primarily affecting patients in active age between 30 and 50 years. Recently, minimally and less invasive screw fixation techniques have become popular as alternative to locked plating. The aim of this study was to analyze biomechanically in direct comparison the primary stability of 3 different cannulated screw configurations for fixation of Sanders type II-B intraarticular calcaneal fractures. Fifteen fresh-frozen human cadaveric lower limbs were amputated mid-calf and through the Chopart joint. Following, soft tissues at the lateral foot side were removed, whereas the medial side and Achilles tendon were preserved. Reproducible Sanders type II-B intraarticular fracture patterns were created by means of osteotomies. The proximal tibia end and the anterior-inferior aspect of the calcaneus were then embedded in polymethylmethacrylate. Based on bone mineral density measurements, the specimens were randomized to 3 groups for fixation with 3 different screw configurations using two 6.5 mm and two 4.5 mm cannulated screws. In Group 1, two parallel longitudinal screws entered the tuber calcanei above the Achilles tendon insertion and proceeded to the anterior process, and two transverse screws fixed the posterior facet perpendicular to the fracture line. In Group 2, two parallel screws entered the tuber calcanei below the Achilles tendon insertion, aiming at the anterior process, and two transverse screws fixed the posterior facet. In Group 3, two screws were inserted along the bone axis, entering the tuber calcanei above the Achilles tendon insertion and proceeding to the central-inferior part of the anterior process. In addition, one transverse screw was inserted from lateral to medial for fixation of the posterior facet and one oblique screw – inserted from the posterior-plantar part of the tuber calcanei – supported the posterolateral part of the posterior facet. All specimens were tested in simulated midstance position under progressively increasing cyclic loading at 2 Hz. Starting from 200N, the peak load of each cycle increased at a rate of 0.1 N/cycle. Interfragmentary movements were captured by means of optical motion tracking and triggered mediolateral x-rays. Plantar movement, defined as displacement between the anterior process and the tuber calcanei at the most inferior side was biggest in Group 2 and increased significantly over test cycles in all groups (P = 0.001). Cycles to 2 mm plantar movement were significantly higher in both Group 1 (15847 ± 5250) and Group 3 (13323 ± 4363) compared to Group 2 (4875 ± 3480), P = 0.048. Medial gapping after 2500 cycles was significantly bigger in Group 2 versus Group 3, P = 0.024. No intraarticular displacement was observed in any group during testing. From biomechanical perspective, screw configuration implementing one oblique screw seems to provide sufficient hindfoot stability in Sanders Type II-B intraarticular calcaneal fractures under dynamic loading. Posterior facet support by means of buttress or superiorly inserted longitudinal screws results in less plantar movement between the tuber calcanei and anterior fragments. On the other hand, inferiorly inserted longitudinal screws seem to be associated with bigger interfragmentary movements

Introduction:. Calcaneal fractures are rare but debilitating injuries assumed to affect particular demographic sub groups. This study aimed to relate epidemiological factors (age, gender, smoking status and social deprivation scores) to the incidence of calcaneal fractures requiring operative fixation over a 10-year period. Methods:. Data (age, gender and smoking status) was extracted from a prospective trauma database regarding calcaneal fractures between September 2002 and September 2012. The Rank of Index of Multiple Deprivation (IMD) scores was collated for each patient and data sub-stratified in 20% centiles. 2010 National Census Data was used to formulate patient subgroups and incidences. Resulting data was subjected to statistical analysis through calculation of relative risk (RR) scores with 95% confidence intervals (95% CI). Results:. 101 calcaneal fractures in 95 patients that underwent operative fixation were identified. 3 open fractures in 3 patients were excluded. In males, the annual incidence of calcaneal fractures requiring operative fixation was 5.10 per 100,000 compared to 1.25 per 100,000 in females (RR 1.60, 95% CI 1.45–1.77). The mean age in males was 36.8 years with a peak incidence between 20–29 years old. The mean age of females was 42.5 years with a peak incidence between 30–39 years old. In females, there was a more even spread throughout all ages with a gradual increase in incidence towards post-menopausal ages. 54 (55.1%) fractures requiring operative fixation occurred in smokers compared to 44 (44.9%) in non-smokers, (RR 2.00, 95% CI 1.39–2.88). Rank of IMD scores revealed 34.0 % of all fractures occurred in the top 20% (RR 1.7, 95% CI 1.28–2.26) most deprived areas and 58.5% of fractures in the top 40% most deprived areas. Conclusions:. This study indicates that male gender, smoking status and high rank of multiple deprivation scores are independent characteristics associated with calcaneal fractures requiring operative fixation

Böhler’s historical tuber-joint angle of the calcaneus has been used since 1931. Surprisingly, there is a paucity of literature on the topic. The aims of this study were to confirm the normal range for Böhler’s angle and determine the angle with the highest accuracy in the diagnosis of calcaneal fractures. A retrospective cohort study was performed. Data were obtained from The St George Hospital digital Picture Archival and Communication System (PACS) and through a review of medical records. The study cohort comprised 212 consecutive patients diagnosed with calcaneal fractures on CT scan, spanning a five-year period from April 2003 to March 2008. An additional 212 patients with normal lateral foot radiographs were used to determine the normal range. Böhler’s angle was measured by two independent observers on lateral xray using the digital angle tool from PACS. Data were analysed using Stata 8 statistical software package. This is the largest study to our knowledge that examines the diagnostic accuracy of Böhler’s angle in fractures of the calcaneus. Contrary to many texts but true to Böhler’s assertions, the mean Böhler’s angle in patients without calcaneal fracture was 29.4 degrees (95% CI, 28.9–30.0 degrees). In this group there was no difference in Böhler’s angle between male and female patients (p> .05), left and right feet (p> .05) or across age (ANOVA, p> .05). In those patients with calcaneal fractures, a Böhler’s angle below 25 degrees was moderately predictive of calcaneal fracture (sensitivity = 100%, specificity = 82%, PPV = 85%, NPV = 100%, LR+ = 5), an angle below 23 degrees was highly predictive of calcaneal fracture (sensitivity = 100%, specificity = 89%, PPV = 90%, NPV = 100%, LR+ = 9) and an angle below 21 degrees was strongly suggestive of calcaneal fracture (sensitivity = 99%, specificity = 99%, PPV = 99%, NPV = 99%, LR+ = 110). A Böhler’s angle of less than or equal to 20 degrees had the highest diagnostic accuracy as there were only two false negatives and one false positive from a total of 424 patients. A Böhler’s angle of 20 degrees or less is highly accurate in determining the presence or absence of calcaneal fracture. These findings are of particular importance when fracture is uncertain as it gives the surgeon a definitive reference point when using Böhler’s angle for assessment of fracture of the calcaneus

Treatment of posterior malleolar (PM) ankle fractures remain controversial. Despite increasing recommendation for small PM fragment fixation, high quality evidence demonstrating improved clinical outcomes over the unfixated PM is limited. We describe the medium-to-long term clinical and radiographical outcomes in younger adult patients with PM ankle fractures managed without PM fragment fixation. A retrospective cohort study of patients aged 18–55 years old admitted under our orthopaedic unit between 1st of April 2009 and 31st of October 2013 with PM ankle fractures was performed. Inclusion criteria were that all patients must mobilise independently pre-trauma, have no pre-existing ankle pathologies, and had satisfactory bimalleolar and syndesmotic stabilisation. Open fractures, talar fractures, calcaneal fractures, pilon fractures, subsequent re-injury and major complications were excluded. All PM fragments were unfixated. Clinical outcomes were evaluated using Foot and Ankle Ability Measure (FAAM) with activities of daily living (ADL) and sports subscale, visual analogue scale (VAS) and patient satisfaction ratings. Osteoarthrosis was assessed using modified Kellgren-Lawrence scale on updated weightbearing ankle radiographs. 61 participants were included. Mean follow-up was 10.26 years. Average PM size was 16.19±7.39%. All participants were evaluated for clinical outcomes, demonstrating good functional outcomes (FAAM-ADL 95.48±7.13; FAAM-Sports 86.39±15.52) and patient satisfaction (86.16±14.42%), with minimal pain (VAS 1.13±1.65). Radiographical outcomes were evaluated in 52 participants, showing no-to-minimal osteoarthrosis in 36/52 (69.23%), mild osteoarthrosis in 14/52 (26.92%) and moderate osteoarthrosis in 2/52 (3.85%). Clinical outcomes were not associated with PM fragment size, post-reduction step-off, dislocation, malleoli fractured or syndesmotic injury. PM step-off and dislocation were associated with worse radiographical osteoarthrosis. Other published medium-to-long term studies reported overall good outcomes, with no differences after small fragment fixation. The unfixated smaller posterior malleolus fragment demonstrated overall satisfactory clinical and radiographical outcomes at 10-year follow-up and may be considered a valid treatment strategy

Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS, Visual Analog Scale for pain - VAS) and were compared between anatomic and nonanatomic DIAFCs using Student's t-test. Demographic data and information about injury severity were collected for each patient. Among the 84 enrolled patients, 6 were excluded while 11 were lost to follow-up. Thirty-nine patients had a nonanatomic reduction while 35 patients had an anatomic reduction (47%). Baseline characteristics were similar in both groups. When we compared the injury severity as defined by the Sanders’ Classification, we did not find a significant difference. In other words, the nonanatomic group did not have a greater proportion of complex fractures. Anatomically reduced DIACFs showed significantly superior results at 12 months for all but one scoring system (mean difference at 12 months: AOFAS 3.97, p = 0.12; LEFS 7.46, p = 0.003; OMAS 13.6, p = 0.002, CFSS 7.5, p = 0.037; VAS −1.53, p = 0.005). Univariate analyses did not show that smoking status, worker's compensation or body mass index were associated with functional outcomes. Moreover, fracture severity could not predict functional outcomes at 12 months. This study showed superior functional outcomes in patients with a DIACF when an anatomic reduction is achieved regardless of the injury severity

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

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

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

Introduction and purpose: Calcaneal fractures account for approximately 2% of all fractures. The calcaneus is the ankle bone that is most frequently fractured. Historically, calcaneal fractures have had a poor prognosis, with sequelae of more or less tolerable pain, flat foot, and different degrees of disability, and can end up with a subsequent subtalar fusion. Most of these fractures occur in the workplace, in men between 40–50 years of age. They are caused by falls from significant heights, and are therefore associated with other fractures such as spinal fractures. A therapeutic guide is applied for the indication of surgery in intrathalamic calcaneal fractures. Materials and methods: Using Sanders’ classification based on diagnosis by CT that differentiates articular fractures from intrathalamic or extraarticular fractures, 47 patients underwent surgery with open reduction and internal fixation with an SPS plate, most of them by a lateral approach, between 1999 and 2006. The patients were all men with a mean age of 34.8 years with intraarticular calcaneal fracture types II and III according to the Sanders’ classification. Results: Intraarticular fractures with displacement accounted for 70.75% of all calcaneal fractures. Our working-age patients, treated surgically, were assessed according to management criteria, medical criteria, scientific criteria and patient-related criteria; total disability due to sequelae has decreased by 75%. Return to former working activities was achieved in 60% of cases. Results were good in 54%, fair in 22%, poor in 23% of cases; surgeon satisfaction was high in 70% of cases and patient satisfaction was excellent to good in 70% of cases. The complications seen were: suture dehiscence, superficial and deep infections and sural nerve dysesthesia. Conclusions: We used CT to diagnose intraarticular fractures and Sanders’ Classification to establish the indication for surgery. Since the establishment of a therapeutic guide for the indication of surgery using an open reduction and internal fixation technique, we have achieved 55% of good results, total disability has decreased by 75%, and we have achieved return to previous work in 60% of the patients. Morbidity due to sequelae has decreased; these sequelae were previously accepted as something to be expected from the moment of fracture with orthopedic treatment

Introduction:. Percutaneous fixation of intraarticular calcaneal fractures adequately restore the subtalar joint with lower soft tissue complications and equivalent short-term results compared to open fixation. However, studies have largely focused on less severe fracture types (Sanders types 2/3). We report our initial experience of this relatively new Mini-open Arthroscopic-assisted Calcaneal Osteosynthesis (MACO) technique for more comminuted calcaneal fractures (Sanders types 3/4). Methods:. We prospectively studied consecutive patients with intraarticular calcaneal fractures requiring surgical fixation between April 2012 and June 2013. MACO involves initial subtalar arthroscopic debridement, with subsequent fluoroscopic-assisted, mini-open reduction and fixation of depressed fragments using cannulated screws. Outcome scores (Manchester-Oxford Foot(MOXFQ), AOFAS Hindfoot and SF-36 questionnaires) and radiological parameters were recorded with a mean follow-up of 12 months (7–13). Results:. There were 9 patients (7 M:2 F) with a mean age of 45.4 years (24–70). All had intra-articular joint depression-type fractures: 5 Sanders type 3 and 4 Sanders type 4. Mean time to surgery was 6.6 days (1–13), operating time was 89.4 minutes (66–130) and inpatient stay was 1.7 days (1–4). All wounds healed without complication and one patient required change of a long screw 11 days post-operatively. There were significant post-operative improvements in the mean Bohler's angle (−2°[−27.2–14.8] to 30°[10.2–41.3], p<0.0002) and angle of Gissane (95°[66.2–111.7] to 111°[101.6–120], p=0.004). Mean outcome scores were 60.8(41–86) for MOXFQ and 75.3(55–92) for AOFAS Hindfoot, with 55.9% developing moderate/severe subtalar joint stiffness. Mean physical and mental SF-36 summary scores were 35.5(24.5–41.5) and 51.7(40.8–61.7) respectively. Conclusion:. We describe the MACO technique for Sanders types 3/4 calcaneal fractures. There were no soft tissue complications with good short-term outcomes, despite a reduction in hindfoot mobility. Restoration of the joint and bone stock without infection is desirable in the event of subsequent arthrodesis. We propose MACO is a valuable alternative technique to open fixation

It is unclear whether combat casualties with complex hindfeet fractures would have an improved outcome with reconstruction or amputation. This study aimed to determine the outcomes of British military casualties sustaining calcaneal fractures. In the 12 years of conflict in Iraq and Afghanistan there were 116 calcaneal fractures in 98 patients. Seventy-four patients (74/98 76%) were contactable, providing follow up data for 85 fractures (85/116 73%). Median follow up was 5-years (64 months, IQR 52–79). Thirty limbs (30/85 35%) had undergone trans-tibial amputation at time of follow-up: there was no association between open fractures and requirement for amputation (p=0.06). Definitive treatment choice had a significant association with later requirement for amputation (p=0.0479). Fifty-two patients (52/74 70%) had been discharged from the military due to their injuries: there was a significant association between amputation and military discharge (p=0.001). Only 17 patients (17/74 23%) had been able to complete a military fitness test since their injury. The median physical component score of the SF-12 quality of life outcome tool for those undergoing amputation was 51.9 (IQR 48.1–54.3). The median for those retaining their limb was 44.1 (IQR 38.6–53.8). The difference between the two cohorts was not statistically significant (p=0.989)

Background: We present the results of the surgical treatment of calcaneal fracture using the technique of closed reduction and stabilization with two pins. Method: 18 calcaneal fractures have been examined in 18 patients, 14 male and 4 female. Some fractures were tongue type and the rest were joint depression type (C,D,E according to Essex- Lopresti classification). Mean follow up time was 2 years. With general or epidural anesthesia and image intensifier we operated using the first pin to reduce closely and stabilize the bone and afterwards we put a second one to secure the result. Result: 10 patients have pain after a lot of work(good), 7 patients have pain after a walk (moderate), 1 patient have pain during the bed resting (bad). Conclusions: The treatment of the calcaneal fracture is a very difficult job. The above mentioned method of surgical technique is looking to have good results in treatment of calcaneal fracture with the specific characteristics

Although modern operative intervention for calcaneal fractures has improved the outcome in many patients, there still is no real consensus on treatment, operative technique, or postoperative management. Vira® is a system for reconstruction-arthrodesis of severe calcaneal fractures, consisting in minimally invasive surgery using cannulation technique. The aim of our study was to elaborate a CPG to assist physiotherapists in decision making and to improve the efficacy and uniformity of care for patients with severe calcaneal fractures. The CPG was developed according to international methods of guideline development. To identify “best evidence” a structured search was performed. When no evidence was available, consensus between experts (physiotherapist and orthopaedic surgeons) was achieved to develop the guideline. To identify “best clinical experience” and “physiopathology reasoning” focus group of practicing physiotherapists was used. They reviewed the clinical applicability and feasibility of the guideline, and their comments were used to improve it. CPG include three phases determined from the physiopathology and biomechanical reasoning of surgical system (weeks after the surgery: 2. a. –5. a. , 5. a. –14. a. , 14. a. –+/−24. a. ). Unfortunately, evidence related to the treatment of severe calcaneal fracture was sparse and often of poor methodologic quality. The recommendations that were included: early onset (2. a. week after the surgery) with early mobility and loading, program of home exercises, manual therapy (articular and miofascial techniques), walking in swimming pool, continuous electromagnetic fields of 99Hz with an intensity of 99 Gaussian during 30 min/day; electrotherapy of the intrinsic muscles of the feet (80Hz; 8:12, 20 mi), a program of active exercises of the feet (dorsiflexion and plantarflexion, not supination and pronation) and resistive exercises of triceps surae muscle (7. a. week), criotherapy and anti-inflammatory positions

As the population ages, we can expect to see more elderly patients with calcaneal fractures. Age alone does not reflect a person’s health or functional status, and should not, therefore, be used as a contraindication to surgical fixation. We report on the management of all patients over 65 years with calcaneal fractures receiving treatment at our institution over a 14-year period. Seventy-three patients > 65 years old with 76 calcaneal fractures treated from 1990 to 2004 were identified from a trauma database. A review of clinical notes was performed; demographics, co-morbidities, mechanism of injury, associated injuries, and management data were collected. For patients receiving operative treatment the fracture classification, operative indications, treatment and outcomes were reviewed. Twenty-seven patients with 29 fractures were treated without fixation, and 46 patients with 47 fractures were treated with fracture fixation. When compared with non-operatively treated patients, those treated operatively had lower mean injury severity scores (8.9 vs. 17.2) and fewer mean co-morbidities (1.0 vs. 2.2). Fractures were treated operatively either with an extensile lateral approach, small incision fixation, or a push screw. Follow-up (two weeks to 50 months) was available on all patients treated operatively, and radiographic follow-up was available on 32 patients. Wound infection and persistent drainage was seen in three and two patients, respectively. There was one non-union. One subtalar fusion was required. Eleven patients subsequently required plate removal. This retrospective review demonstrates that operative treatment of calcaneal fractures in carefully selected, elderly patients can result in good outcomes with acceptable complication rates. The complication profile for patients over 65 with calcaneus fractures appears to be similar to younger patients

Opinions is divided among surgeons whether to operatively fix displaced calcaneal fractures in elderly patients and heavy smokers. In a long term follow-up of operatively treated calcaneal fractures, we considered several factors that could affect outcomes and complication rates. Method: 59 calcaneal fractures in 54 patients that underwent operative fixation for displaced intra-articular fractures from April 1995 to January 2006 were reviewed. There were 18 Tongue type and 41 Joint depression fractures on X-rays. Of 38 available CT scans, 25 were Sanders Type II and 13 were Types III and IV fractures. Average interval to surgery was 6 days. Postoperative mobilisation regime was passive range of motion immediately following surgery with non weight bearing for 6 weeks. Weight bearing was started at 6–8 weeks. On follow-up, patients were assessed with clinical and radiological exam, completed Short Form-36 (SF-36), the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot scale and Visual Analogue Scale (VAS) scores. Results: The duration of follow-up was between 6 months to 11.2 years (6.4 years). The pre and post operative Bohler angles were 8° ± 11° and 29° ± 6° respectively. There was significant limitation of subtalar movement on the operated side irrespective of the presence of arthritis. The average AOFAS, SF-36 and VAS scores were 79, 58 and 3 respectively. Good results were associated with age < 50 years, ASA grade I, pre-op Bohler angle of < 5° and Sanders < IIC. 89% of patients returned to their previous level of activity after an average of 6.5 months. Smoking was not associated with early or late complication rates and did not affect outcome. Conclusions: We think that advanced age and smoking are not contraindications for operative fixation of displaced calcaneal fractures

We have assessed the long-term results after operative and non-operative treatment of undisplaced and displaced calcaneal fractures. At a mean of 6.5 years, we reviewed 70 patients with a calcaneal fracture who were divided into four groups: group 1, 18 patients with undisplaced fractures and a normal Böhler’s angle (BA) who had been treated non-operatively; group 2, 23 with intra-articular fractures and a BA < 10° who had been treated non-operatively; group 3, 13 with intra-articular fractures and a BA > 10° who had been treated surgically; and group 4, 16 with intra-articular fractures and a BA < 10° who had been treated surgically. The results were assessed by a clinical score considering pain, return to work, return to physical activity, change in shoe-wear and the requirement for subtalar arthrodesis. Patients with undisplaced calcaneal fractures had a good outcome. Those with displaced fractures treated surgically who presented at follow-up with a BA > 10° had a satisfactory functional outcome and those with displaced fractures who had non-operative treatment had a poor outcome. The poorest outcome was consistently seen in patients who were treated operatively without restoration of BA. Open reduction and internal fixation of intra-articular calcaneal fractures can only be expected to benefit those patients in whom nearly anatomical reconstruction is obtained

Opinions differ among surgeons whether to operatively fix displaced calcaneal fractures in smokers. In a long term follow-up of operatively treated calcaneal fractures, we considered several factors that could affecting outcomes and complications. Method: 59 calcaneal fractures in 54 patients that underwent operative fixation for displaced intra-articular fractures from April 1995 to January 2006 were reviewed. There were 18 Tongue type and 41 Joint depression fractures on X-rays. Of 38 available CT scans, 25 were Sanders Type II and 13 were Types III and IV fractures. Average interval to surgery was 6 days. Postoperative mobilisation regime was passive range of motion immediately following surgery with non weight bearing for 6 weeks. Weight bearing was started at 6–8 weeks. On follow-up, patients were assessed with clinical and radiological exam, completed Short Form-36 (SF-36), the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot scale and Visual Analogue Scale (VAS) scores. Results: The duration of follow-up was between 6 months to 11.2 years (6.4 years). The pre and post operative Bohler angles were 8° ± 11° and 29° ± 6° respectively. There was significant limitation of subtalar movement on the operated side irrespective of the presence of arthritis. The average AOFAS, SF-36 and VAS scores were 79, 58 and 3 respectively. Good results were associated with age < 50 years, ASA grade I, pre-op Bohler angle of < 5° and Sanders < IIC. 89% of patients returned to their previous level of activity after an average of 6.5 months. Smoking was not associated with early or late complication rates and did not affect outcome. Conclusions: We think that smoking is not a contraindication for operative fixation of displaced calcaneal fractures

Aim: The purpose of this study was to report the long-term follow-up (mean of 15 years) of patients with displaced intra-articular calcaneal fractures from a randomised controlled trial published in 1993. Patients and Methods: 46 patients (82% of patients in the initial study group) were alive at a mean of 15 years post injury. The patients had been randomly allocated to either conservative or operative (Soeur and Remy technique) treatment in the original study. Clinical (AOFAS, FFI and calcaneal fracture score) and radiological (Böhler’s angle and calcaneum height) outcome measures were used. The grade of osteoarthritis was also assessed at long-term follow-up. Results: 26 patients (57%) were reviewed and these patients served as the focus of the study (11 conservative and 15 operative). The clinical outcomes after conservative treatment were not found to be different from those after operative treatment, scores of the AOFAS were 78.5 and 70 respectively (p = 0.11); scores of the FFI were 24.4 and 26.9 respectively (p = 0.66) and calcaneal fracture scores were 70.1 and 63.5 respectively (p = 0.41). The radiological outcomes after conservative treatment were not found to be different from those after operative treatment, Böhler’s angles were 10° and 16° respectively (p = 0.07) and the height of the calcaneum were 37mm and 36mm respectively (p = 0.57). There was no difference in the grade of osteoarthritis between the groups. Conclusion: The functional and radiological long-term outcomes after conservative treatment of displaced intra-articular calcaneal fractures were equivalent to those after operative treatment. The operative technique showed no benefit compared to conservative treatment at long-term follow-up. There was a trend for higher scores on clinical outcomes with conservative treatment

Introduction and Objective. Management of bone loss associated with bone contamination or infection represents a double biological and clinical challenge frequent in traumatology. The advent of new biomaterials can allow a different approach in the treatment of bone gap. The purpose of this study was to evaluate the prophylactic and therapeutic effectiveness of addition of a new absorbable bone substitute (BS) eluting different antibiotics in reconstruction of bone defects after infections and fractures with soft tissue damage. Materials and Methods. We conducted a review of patients with contaminated or infected bone defects treated using a new biomaterial, a porous composite of collagen matrices and Beta tricalcium phosphate (β TCP), able to provide a long-term release of different antibiotics. We have included treatment of osteomyelitis and osteosynthesis of exposed fracture (Gustilo Anderson 1–3b) or fractures with soft tissue damage and high risk of contamination. Surgical technique included debridement filling bone defect with BS eluting antibiotics, osteosynthesis (plate, nail, external fixator, kirschner wire), soft tissue coverage, and systemic antibiotic therapy. Radiographic and clinical data including complications (wound dehiscence, superficial or deep infection, osteomyelitis) were collected. Results. We treated 25 patients (21 male, 4 female) with mean age 47 yrs. (range 21–83). The locations treated (for incidence) was: 9 femurs (7 plates, 2 nail), 7 calcanei (one bilateral), 3 tibias, 2 forearms, 2 metatarsi, 2 hands, 1 elbow. 6 patients had large bone loss. 7 patients had bone infections (4 were Cierny Madern 4); 8 patients had osteosynthesis of exposed fractures Gustilo Anderson 1–3b (9 plate, one bilateral calcaneus). 8 patients had treatment for pseudoarthrosis of exposed fractures (6 femurs, 1 forearm, 1 metatarsus) and 3 patients a prophylactic treatment for calcaneal fractures with soft tissue damage. 4 deep infection were treated with multiple surgical debridement and new filling bone defect with BS eluting antibiotic with infection eradication. We have used a combination of vancomycin and gentamicin on 15 cases, vancomycin alone on 4 cases, combination of vancomycin and amikacin on 1 case and amikacin and Linezolid in a targeted multi drug resistance. At final follow-up functional outcome was good in all cases with bone healing. Conclusions. Extensive debridement is a fundamental requisite for eradication of bone infections and contamination. Filling of the bone void with loaded bio-composite eluting diversifiable local antibiotics with synergistic anti-biofilm activity is desirable. Treatment of this bone defects are advantaged when combining his reconstruction with BS and the possibility of release high antibiotic concentration at least for 10 days. This is an important complementing prophylactic and therapeutic antimicrobial option with adjuvant role to systemic therapy that enlarges the success rate

The June 2014 Foot & Ankle Roundup. 360 . looks at: peroneal tendon tears associated with calcaneal fractures; syndesmosis procedure for first ray deformities; thromboprophylaxis not necessary in elective Ilizarov surgery; ankle replacement gaining traction in academic centres; some evidence for PRP and; fusion nailing and osteotomy an effective treatment for symptomatic tibial malunion

We reviewed in retrospect the preliminary results of ilizarov type fixator for the treatment of severely comminuted calcaneal fractures. Between February 2006 and December 2008 we dealt with six severely comminuted calcaneal fractures in six patients. Two of which were open type Gustillo IIIa. Mean age was 43 years old(28–56 years old) two of which were female and four male. Preoperatively all fractures were checked by x-ray and computed tomography and were all rated as Sanders type IV. The open fractures were treated within 6 hours and the closed ones the following day. After the positioning of the ilizarov tibial and foot frame, an indirect reduction was achieved using the Ilizarov olive wires. Mean follow up was 20 months (9 to 36 months). Results were rated as very good in two patients (33%), good in three patients (50%) and fair in one (17%). So far no re-operation has been required and four of the patients are back to work. We conclude that the ilizarov system, even with indirect reduction can give very promising results in severely comminuted and complex calcaneal fractures whereas internal fixation has questionable success and many complications

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

Introduction: There is a controversy regarding conservative or surgical treatment of calcaneal fracture. We report our experience in surgical treatment of calcaneal fractures. Materials and Methods: Between March 1998 and May 2004, 30 patients with 32 calcaneal fractures were treated surgically in our departments. Twenty four fractures were caused after a fall from height, 4 fractures were consequence of a road accident, 2 fractures after a blast injury and one after a football injury. There were 4 females and 26 males. Two cases were bi-lateral fractures. Age range 20–66 (mean 33). Follow-up time 7 to 72 months (mean 24 months). The fractures were classified according to Sanders classification: there were 22 patients with Sanders III, 8 patients with Sanders IV and one patient with Sanders II. All patients were operated with the same procedure and the same surgeon. The surgical procedure was delayed from 10 to 14 days post trauma, until swelling subsided. Open Reduction Internal Fixation was performed using lateral approach, “L” shape with subperiosteal dissection of lateral wall, and using a calcaneal reconstruction plate. Results: The functional outcome was evaluated according to Rowe Score. The clinical results were excellent in 3 patients (10%), good in 22 patients (70%), fair in 4 patients (14%) and poor in 2 patients (6%). The Boehler angle was reconstructed in 29 of 32 calcaneus. 3 patients returned to their previous level of activity, 9 patients returned to work, 14 patients mentioned some pain in the site of the operation. Two patients were treated successfully with oral antibiotics for superficial wound infection. Six patients suffered from peripheral nerve damage. One patient experienced subtalar pain, and underwent a subtalar arthrodesis, furthermore the patient developed Complex Regional Pain Syndrome (CRPS), finally he underwent below knee amputation (BKA). One patient had a flap necrosis and underwent sural flap coverage with excellent results. All the patients were recognized in a process to be recognized as disabled by the social security. Conclusion: Our results were good in majority of patients according to the known classification systems. However, the recovery period from calcaneal fractures is long and the majority of patients do not achieve their previous functional level. The secondary gain might bias the results

Objectives. This study aimed to investigate the functional effects of microRNA (miR)-214-5p on osteoblastic cells, which might provide a potential role of miR-214-5p in bone fracture healing. Methods. Blood samples were obtained from patients with hand fracture or intra-articular calcaneal fracture and from healthy controls (HCs). Expression of miR-214-5p was monitored by qRT-PCR at day 7, 14 and 21 post-surgery. Mouse osteoblastic MC3T3-E1 cells were transfected with antisense oligonucleotides (ASO)-miR-214-5p, collagen type IV alpha 1 (COL4A1) vector or their controls; thereafter, cell viability, apoptotic rate, and the expression of collagen type I alpha 1 (COL1A1), type II collagen (COL-II), and type X collagen (COL-X) were determined. Luciferase reporter assay, qRT-PCR, and Western blot were performed to ascertain whether COL4A1 was a target of miR-214-5p. Results. Plasma miR-214-5p was highly expressed in patients with bone fracture compared with HCs after fracture (p < 0.05 or p < 0.01). Inhibition of miR-214-5p increased the viability of MC3T3-E1 cells and the expressions of COL1A1 and COL-X, but decreased the apoptotic rate and COL-II expression (p < 0.05 or p < 0.01). COL4A1 was a target of miR-214-5p, and was negatively regulated by miR-214-5p (p < 0.05 or p < 0.01). Overexpression of COL4A1 showed a similar impact on cell viability, apoptotic rate, and COL1A1, COL-II, and COL-X expressions inhibiting miR-214-5p (p < 0.01). Conclusion. Inhibition of miR-214-5p promotes cell survival and extracellular matrix (ECM) formation of osteoblastic MC3T3-E1 cells by targeting COL4A1. Cite this article: Q. S. Li, F. Y. Meng, Y. H. Zhao, C. L.

Aims: A study was undertaken using foot pressure analysis, to assess the biomechanical outcomes following calcaneal fractures using the HR Mat and to assess their correlation with function. Methods: Twenty four individuals who had been treated for unilateral, intra-articular comminuted calcaneal fractures performed 4 walking trials. 14 patients had operative treatment and 10 were treated conservatively. Results: There was significant restriction in subtalar and ankle movements on the affected side in both groups. Peak pressures in the midfoot and fifth metatarsal head were significantly higher in the injured foot compared to the normal side. Peak values of forces transmitted by the fractured foot were significantly lower (ANOVA < 0.001). Hindfoot movements, foot pressure and force measurements did not correlate with the AOFAS and Bristol scores. Conclusions: Calcaneal fractures cause significant alteration of loading in the foot. Altered loading patterns do not appear to have an influence on the functional outcome

We report the 15 year follow-up of displaced intra-articular calcaneal fractures from a randomised controlled trial of conservative versus operative treatment. Of the initial study, 46 patients (82%) were still alive and 26 patients (57%) agreed to review. The clinical outcomes were not different between operative versus conservative treatment. American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale: p = 0.11; Foot Function Index (FFI): p = 0.66; and calcaneal fracture score: p = 0.41. The radiological outcomes also were not different between both groups. Böhler’s angle: p = 0.07; height of calcaneum: p = 0.57; and grade of osteoarthritis of the subtalar joint: p = 0.54. There was no correlation between Böhler’s angle and the outcome measures in either group. The results of this 15 year follow-up of displaced intra-articular calcaneal fracture randomised controlled trial demonstrate similar findings to those at one year follow-up

The October 2014 Foot & Ankle Roundup360 looks at: multilayer compression bandaging superior for post-traumatic ankle oedema; compression stockings for ankle fractures; weight bearing ok in Achilles tendon ruptures; MRI findings can predict ankle sprain symptoms; salvage for malreduced ankle fractures; locking fibular plates are more expensive; is fixation better early or late in pilon fractures?; and calcaneal fracture fixation not for subtalar arthropathy

The February 2015 Trauma Roundup. 360 . looks at: Evaluating the syndesmosis in ankle fractures; Calcaneal fracture management an ongoing problem; Angular stable locking in low tibial fractures did not improve results; Open fractures: do the seconds really count?; Long-term outcomes of tibial fractures; Targeted performance improvements in pelvic fractures

The October 2013 Foot & Ankle Roundup. 360 . looks at: Operative treatment of calcaneal fractures advantageous in the long term?; Varus ankles and arthroplasty; Reducing autograft complications in foot and ankle surgery; The biomechanics of ECP in plantar fasciitis; Minimally invasive first ray surgery; Alcohol: better drunk than injected?; Is it different in the foot?; It’s all about the temperature

Aim: The aim of the study is to evaluate the usefulness of the MDCT scan in the diagnosis of calcaneal fractures and its use in the surgical treatment. Material. 112 calcaneal fractures were examined with a MDCT scan (slices one to two mm, pitch 1.5) with multilevel reconstruction as well as three dimensional reconstruction. The fractures were classified according to Munich classification system. Findings that were evaluated were the involvement of the subtalar joint, the number of fragments of the posterior facet and the extent of displacement. Results: There were 85 intraartiular fractures and 27 extraarticular. 32 fractures were of type I according to Munich classification system (extraarticular without displacement). 15 fractures were of type II (extraarticular with some displacement). 2 fractures were of type III (intraarticular without displacement). 27 were of type IV (two fragments). 19 were of type V (with free fragments in the joint and 17 were type VI (more than four fragments). Conclusion: The above mentioned radiological method of evaluating calcaneal fractures offers a quick diagnosis since it can depict the fragments and its displacement very accurately. Furthermore this method permits a very precise preoperative planning for the surgical treatment of these injuries

Introduction: The aim of our study was to assess any difference in outcome between non-surgical and surgical treatment of displaced calcaneal fractures. Materials and Methods: We studied 40 patients between 2000 to 2005 with displaced calcaneal fractures. Patients with significant co-morbidities were excluded. Two groups of 14 patients, surgery vs. no surgery were compared for age, sex, length of follow-up, fracture type by Essex-Lopresti classification and SF-36 outcome score. The non-surgical group underwent treatment with rest, ice, compression, elevation and the surgical group underwent fixation with an AO calcaneal plate through an extended lateral approach. Results: There was no statistically significant difference between the surgical and conservatively treated groups for age, sex, time since injury and fracture type according to Essex-Lopresti but a highly statistically significant difference in SF-36 outcomes between the two groups favouring surgically treated calcaneal fractures. Summary: Displaced fractures of the calcaneum are a significant injury affecting patients general health. In the literature controversy exists as to whether operative or non-operative treatment is better for this type of fracture. Conclusion: Although the numbers are small, our study favours operative intervention, if possible, for this controversial fracture

Background: The reported incidence of calcaneocuboid joint (CCJ) involvement in calcaneal fractures varies considerably. It is largely unknown to what extend CCJ involvement accounts for outcome in these fractures. Therefore, the goal of this study was to analyse the incidence and effects of CCJ involvement in calcaneal fractures. Patients and Methods: The clinical records of 106 patients, treated between 2001–2007, were reviewed for fracture classification, injury mechanism, surgical treatment and complications. In a prospective cross-sectional study 44 patients were assessed clinically (SF-36 score, AOFAS) and radiographically. Gait analysis was performed using dynamic pedography. Results: 68 % of all fractures had involvement of the CCJ. Fractures with CCJ involvement were caused by a more severe injury than fractures without CCJ involvement (Mann-Whitney-Test, p=0.03), this is reflected by a strong association between CCJ involvement and fracture classification (Spearman, p< 0.006). Patients with involvement of the CCJ – especially those with a postoperative step in the CCJ – achieved a lower SF-36 score as well as a lower AOFAS score than patients without CCJ involvement. CCJ involvement was associated with more difficulties in walking on rough surface (Spearman, p = 0,020). Limitations during gait were confirmed by dynamic pedography. Grading of posttraumatic OA was associated with fracture classification. (χ. 2. -test p< 0.02) and quality of reduction (χ. 2. -test p< 0.01). Conclusions: These results indicate that calcaneal fractures with involvement of the calcaneocuboid joint are associated with more severe trauma and worse outcome. Thus the CCJ should be given more credit during surgery and in our research efforts

Anti-vehicle mines (AV) and Improvised Explosive Devices (IEDs) remain the most prevalent threat to Coalition troops operating in Iraq and Afghanistan. Detonation of these devices results in rapid deflection of the vehicle floor resulting in severe injuries to calcaneus. Anecdotally referred to as a ‘deck-slap’ injury, there have been no studies evaluating the pattern of injury or the effect of these potentially devastating injuries since World War II. Therefore the aim of this study is to determine the pattern of injury, medical management and functional outcome of UK Service Personnel sustaining calcaneal injuries from under-vehicle explosions. From Jan 2006 – Dec 2008, utilising a prospectively collected trauma registry (Joint Theatre Trauma Registry, JTTR), the records of all UK Service Personnel sustaining a fractured calcaneus from a vehicle explosion were identified for in depth review. For each patient, demographic data, New Injury Severity Score (NISS), and associated injuries were recorded. In addition, the pattern of calcaneal fracture, the method of stabilisation, local complications and need for amputation was noted. Functional recovery was related to the ability of the casualty to return to military duties. Forty calcaneal fractures (30 patients) were identified in this study. Mean follow-up was 33.2 months. The median NISS was 17, with the lower extremity the most severely injured body region in 90% of cases. Nine (30%) had an associated spinal injury. The overall amputation rate was 45% (18/40); 11 limbs (28%) were amputated primarily, with a further 3 amputated on return to the UK. Four (10%) casualties required a delayed amputation for chronic pain (mean 19.5 months). Of the 29 calcaneal fractures salvaged at the field hospital, wound infection developed in 11 (38%). At final follow-up, only 2 (6%) were able to return to full military duty with 23 (76%) only fit for sedentary work or unfit any military duty. Calcaneal injuries following under-vehicle explosions are commonly associated with significant polytrauma, of which the lower limb injury is the most severe. Spinal injuries were frequently associated with this injury pattern and it is recommended that radiological evaluation of the spine be performed on all patients presenting with calcaneal injuries from this injury mechanism. The severity of the hindfoot injury witnessed is reflected by the high infection rate and amputation rate seen in this cohort of patients. Given the high physical demands of a young, active military population, only a small proportion of casualties were able to return to pre-injury duties. We believe that the key to the reduction in the injury burden to the soldier lies in the primary prevention of this injury. Work is currently on going to develop experimental and numerical models of this injury in order to drive future mitigation strategies

These results support the use of an injectable, in situ hardening calcium phosphate paste to prevent the early loss of calcaneal height and maintain a more anatomic calcaneal reduction. The purpose of this prospective randomized controlled trial was to determine whether ORIF plus an injectable bioresorbable calcium phosphate paste (_-BSM) is superior or inferior to ORIF alone in the treatment of calcaneal bone voids encountered after operative treatment of displaced intraarticular fractures of the calcaneus. Forty-four patients (forty-eight displaced intraarticular calcaneal fractures necessitating operative fixation) presenting to a Level One trauma center were enrolled into the study and randomized 1:1 to receive ORIF and injection of _-BSM or ORIF alone. All patients had a standardized ORIF thru a lateral approach by a single surgeon (R.B.). The primary outcome measure was the maintenance of post- operative Bohler’s angle at six weeks, three months, and six months. Other outcome measures included the SF-36 and LEM (Lower Extremity Measure) Score at six months. Five patients with seven calcaneal fractures were lost to follow up leaving thirty-nine patients with forty-one calcaneal fractures (85%) for analysis. Twenty-one were randomized into the ORIF and _-BSM group and twenty into the ORIF alone group. There was no statistical difference between the two groups with regard to age, sex, mechanism of injury, initial Bohler’s angle, or type of fracture. There was no difference between the groups in the degree of collapse of Bohler’s angle at six weeks and three months when compared to initial post-operative values. However, at six months the mean collapse of the _-BSM and ORIF group was 5.6° and ORIF alone was 10.6°. This was statistically significant (p< 0.01).

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

Introduction The results of open reduction and internal fixation of displaced intra-articular calcaneal fractures has been shown to be superior to closed management. We report our early experience with the AO locking calcaneal plate for these injuries in particular looking for wound complications. Methods Between December 2001 and March 2003 a total of 28 patients with 29 displaced intra-articular calcaneal fractures were treated by two surgeons. The average delay from injury to time of surgery was 11 days. A standard “L” shape lateral approach was used with the patient in a lateral decubitus position. Reduction was temporarily held with K wires before the locking plate was applied, with the bending tools used for in-situ plate moulding. Wounds were closed over a drain using Allgower-Donati sutures after haemostasis. Stitches were removed at two weeks when the wounds had healed. Results Of the 29 fractures treated there was only two minor wound problems. In one patient this occurred after using the larger plate and consisted of slight necrosis at the inferior corner of the wound, which healed non-operatively. There have been two patients requiring removal of their plates between 10 and 15 months after surgery. They both complained of lateral pain, which may have been due to the plate being bulkier than other currently used plates. After removal both patients had immediate relief from their symptoms. The AO locking plate offers advantages over the standard plate. These include the option for locking screws as well as 2.7 mm and 3.5 mm screws, increased strength, and the ability to mould the plate in-situ using the bending irons in the screw holes. This in-situ moulding allows better contouring of the plate. On one occasion even this plate was too large and required trimming to fit the bone. We have not experienced an increase in wound problems due to bulkier plate. Conclusions Our early experience with the AO Locking plate has been positive, with minimal complications. We would recommend the use of this plate for fixation of displaced intra-articular calcaneal fractures, and suggest the need for a smaller plate to be designed

We describe the surgical technique and results of arthroscopic subtalar release in 17 patients (17 feet) with painful subtalar stiffness following an intra-articular calcaneal fracture of Sanders’ type II or III. The mean duration from injury to arthroscopic release was 11.3 months (6.4 to 36) and the mean follow-up after release was 16.8 months (12 to 25). The patient was positioned laterally and three arthroscopic portals were placed anterolaterally, centrally and posterolaterally. The sinus tarsi and lateral gutter were debrided of fibrous tissue and the posterior talocalcaneal facet was released. In all, six patients were very satisfied, eight were satisfied and three were dissatisfied with their results. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from a mean of 49.4 points (35 to 66) pre-operatively to a mean of 79.6 points (51 to 95). All patients reported improvement in movement of the subtalar joint. No complications occurred following operation, but two patients subsequently required subtalar arthrodesis for continuing pain. In the majority of patients a functional improvement in hindfoot function was obtained following arthroscopic release of the subtalar joint for stiffness and pain secondary to Sanders type II and III fractures of the calcaneum

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)

A consensus regarding management of calcaneal fractures eludes orthopaedic surgeons. While operative treatment has gained more acceptance, surgical morbidity remains high. We undertook a retrospective review of early complications and radiological outcomes following internal fixation of calcaneal fractures in our unit over 15 months. A consecutive series of 33 patients who underwent fixation of the Calcaneus was selected. Patient records, X-rays and scans were reviewed. 37 fractures in 33 patients underwent fixation. 81 % were male. Mean age at surgery was 37yrs (19 -59yrs). 35 % were operated within 1 wk of injury and 13% after 2 wks of injury. 43% were Sanders' type III, 18% type II and 13% tuberosity avulsion fractures. 63% had a reversed/zero Bohler's angle. Mean post-op Bohler's angle was 32 degrees. Overall complication rate was 32%, with a combined deep infection rate of 8%. All patients with infection were male, and 70% were smokers. 86% were above 40yrs of age (mean 47yrs). The deep infection rate for intra-articular fractures was 3% and for tuberosity avulsion fractures 40%. Majority of patients with wound complications had been operated within 7 days of injury. Males over 40yrs and smokers seem to be at most risk of wound complications. Time to surgery/delay in surgery up to 2 wks did not seem to have any adverse consequences. Complications increase with fracture complexity and avulsion fractures have highest risk of wound breakdown. Near anatomical restoration of the articular surface is possible in most

Aims: Internal Fixation of complex calcaneal articular fractures is debated: a perfect and upheld reduction is challenging. Could locked screws calcaneal plates drive back the limits of Internal Fixation instead of initial arthrodesis, involve a faster rehabilitation and improve the results?. Methods: Between 2004 and 2008, 32 patients (26 men, 6 women), sustained 35 complex calcaneal articular fractures. Age: 41.46 [17–71] ±15.99 years. Pre operative TDM: ≥3 displaced articular fragments (Sanders III: 22 and IV: 13). ORIF by the same surgeon, between D4 and D7, through a lateral approach and using an AO LCP. ®. locked screws calcaneal plate. Intra operative X-ray controls, postoperative TDM. Articular re-education at D30. Complete weight bearing at D90. Follow-up until 60 months (X-ray and Kitaoka score). Results: Obtained and upheld anatomical articular reduction -Boehler’s angle, talo and cubo-calcaneal congruence-: (35/35). Bone healing: 8 weeks (21/35) and 12 weeks (14/35). Delayed wound healing -smokers-: (6/35). Anatomical articular upholding after 12 months: (35/35). Plate ruptures at D90 without displacement: (2/35). Walking without crutch after D90: (35/35). Mean follow up: 40 months. Conclusion: Locked screws calcaneal plate used for the fixation of complex articular calcaneal fractures showed no displacement in the primary and secondary healing time. These facts limit the place of initial arthrodesis and streamline the initial recovery process. This may be beneficial for clinical use and the long term follow-up

Purpose: We wanted to ascertain whether the advantages of functional treatment on trophicity could be combined with the advantages of surgical treatment on anatomic results in patients with displaced calcaneal join fractures. Material and methods: Using the AO 3.5 reconstruction plates with specific stereotypic modelling we were able to obtain solid fixation in almost all cases of calcaneal joint fractures using a rigorous technique and following precise principles, notably the direction of the screw into the sustentaculum tali.As the osteosynthesis is very stable, we postulate that partial and progressive early weight bearing would be acceptable as long as pain was under a threshold level used as sign of micromobility. The first cases were very favourable so we extended this method, using it as a routine procedure for all cases (excepting those with an associated injury excluding weight bearing). Among 122 fractures operated with this method, 118 were reviewed. Results: According to the Duparc classification, we treated one type 2, 34 type 3, 76 type 4 and seven type 5 fractures. Weight bearing was initiated on the average at 14 days, with a median of seven days. The Boehler angle improved from 0° preoperatively to 22° postoperatively. We did not have any cases of secondary displacement greater than 2°. The functional outcome was, according to the SOFCOT criteria: very good 34.5%, good 41.4%, fair 9.5% and poor 0%. Physical results (SOFCOT criteria) were: very good 17.2%, good 54.3%, fair 26.7%, poor 1.7%. Anatomic results according to AFC criteria were: very good and good 69%, fair 25.9%, poor 5.1%. Discussion: These result demonstrate that a rigorous therapeutic management scheme can combine the advantages of functional and surgical treatment of displaced calcaneal joint fractures. Early weight-bearing below the pain threshold was effective since all our bilateral cases could be discharged after walking a few steps. Recovery was more rapid when weight bearing was late. Crutches could be abandoned at two months on the average. Conclusion: We believe that solid osteosynthesis is possible in almost all cases of displaced calcaneal fractures with joint involvement if a rigorous technique is used. Progressive early weight bearing below the pain threshold is a significant adjuvant factor favouring rapid and quality outcome

Tarsal fractures are rare in children. Clinical and radiographic evaluation of these injuries can be difficult. We present a retrospective study documenting all tarsal fractures presenting to an inner-city children’s hospital in the UK over a fifteen year period. Of 70 case notes retrieved from the hospital database, 7 patients were excluded due to inadequate data. This resulted in 69 tarsal injuries in 63 patients being included. Mean age at presentation was 9.3 years (2.5 – 13.9). 80% were male. 72% were calcaneal fractures, 12% cuboid, 9% navicular, 4% talus and 2% medial cuneiform. The main method of diagnosis was plain x-rays. Cause of injury was predominantly fall from height, crush or road traffic accident. 25% had another associated lower extremity injury. Three patients had bilateral tarsal injuries. Only 3% had upper limb injuries and there were no injuries with spinal involvement. Calcaneal fractures were treated with a short leg cast for a mean time of 4.1 weeks (2–6). Mean time to recovery was 5.7 weeks (2–20). Mean time to discharge from clinic was 7 weeks (2–40). There were two patients with open fractures requiring surgical debridement. One patient with a talar fracture had percutaneous fixation. Only one patient re-presented with pain following discharge. X-rays showed healing avascular necrosis of the proximal talus. Tarsal fractures are rare, usually benign and most require simple immobilisation for only a short period of time. Surgical intervention is only occasionally required in complex injuries. Complications and long term problems are rare, even following open injuries

Our purpose was to evaluate the use of indirect and closed reduction with Ilizarov external fixator in intraarticular calcaneal fractures. In a period of 3 years, 16 patients with 18 intraarticular fractures of calcaneus (eleven type III and seven type IV according to Sanders classification) were treated with the Ilizarov fixator. Twelve patients were male and four female. The average age was 42 years (range 25 – 63 years). Three fractures were open. Fractures were evaluated by preoperative radiographs and CT scans. Restoration of the calcaneal bone anatomy was obtained by closed means using minimally invasive reduction technique by Ilizarov fixator. Arthrodiatasis and ligamento-taxis, and closed reduction of the subtalar joint were performed in 14 cases. In 4 cases the depressed posterior calcaneal facet was elevated by small lateral incision and stabilized in frame by wires. Postoperatively, partial, early weight bearing was encouraged in all patients. The mean follow-up period was 1,5 years (range 1 – 3 years). The AOFAS Ankle – Hindfoot Score, and physical examination were used in functional evaluation. The average score was 79,8 (range 72 – 90). Six patients had limited degenerative radiological findings of osteoarthrosis about the subtalar joint and three of them had painful subtalar movement. One of the patients complained of heel pad pain. Nine (6.25%) grade II pin tract infections were detected from a total of 144 wires. No secondary reconstructive procedures, including osteotomies, subtalar fusions, or amputations, have been done. Indirect closed reduction of calcaneal bone anatomy and arthrodiatasis of subtalar joint with Ilizarov external fixator is a viable surgical alternative for intraarticular calcaneal fractures

Aim: Our purpose was to evaluate the use of indirect and closed reduction with Ilizarov external fixator in intra-articular calcaneal fractures. Materials and Methods: In a period of 5 years (2004–2008), 26 patients with 29 intra-articular fractures of calcaneus (eighteen type III and eleven type IV according to Sanders classification) were treated with the Ilizarov fixator. Twenty-one patients were male and five female. The average age was 45 years (range 22 – 67 years). Five fractures were open. Fractures were evaluated by preoperative radiographs and CT scans. Restoration of the calcaneal bone anatomy was obtained by closed means using minimally invasive reduction technique by Ilizarov fixator. Arthrodiatasis and ligamentotaxis, and closed reduction of the subtalar joint were performed in 24 cases. In 5 cases the depressed posterior calcaneal facet was elevated by small lateral incision and stabilized in frame by wires. Postoperatively, partial, early weight bearing was encouraged in all patients. Results: The mean follow-up period was 2,1 years (range 1 – 4 years). The AOFAS Ankle – Hindfoot Score, and physical examination were used in functional evaluation. The average score was 77,4 (range 70–90). Seven patients had limited degenerative radiological findings of osteoarthrosis about the subtalar joint and three of them had painful subtalar movement. Two of the patients complained of heel pad pain. Nine patients had grade II pin tract infections and were detected from a total of 258 wires. No secondary reconstructive procedures, including osteotomies, subtalar fusions, or amputations, have been done. Conclusion: Indirect closed reduction of calcaneal bone anatomy and arthrodiatasis of subtalar joint with Ilizarov external fixator is a viable surgical alternative for intra-articular calcaneal fractures

Introduction and purpose: Calcaneal fractures are relatively common. The severity of this condition is due to the residual functional limitation. There are several therapeutic alternatives. Materials and methods: We carried out a retrospective study of 70 patients with calcaneal fractures, divided into two groups. The first group of 35 patients was treated with bone synthesis using pins and the second group of 35 with bone synthesis with a low-profile plate and screws. We analysed epidemiological data, injury mechanism, type of fracture and complications. We calculated the reduction of Böhler’s angle and return to work. The clinical and functional results were analysed using the AOFAS scale. Results: The mean age and injury mechanism were very similar in both groups. In the pin group, the fracture type was mainly grade 2 according to the Sanders classification, while in the plate group it was grade 3. The reduction of Böhler’s angle was greater in the plate group. There were no statistically significant differences between the two groups with regard to return to work. However the final AOFAS score was 82.7 in the plate and 69.8 in the pin group. Conclusions: A fracture of the calcaneus is a complex pathology, especially because of the functional limitation it leaves behind. There were fewer complications in the plate group, except for skin problems

CT- scan as an management tool is being used extensively in managing calcaneal fractures. We set out to see if a CT-scan makes any difference to the management plan as obtained by looking at the plain radiograph. We also looked at the correlation with the actual management. Methodology: This was a retrospective study involving 24 patients with fracture of the calcaneum. These patients had both a plain radiograph and a CT- scan to help decide on management. The actual management that each of these patients had was documented. Three consultants who were blinded to the actual management and names of the subjects were independently asked to grade the radiographs, as operative or non-operative. They were then similarly, asked to decide on operation or no-operation based on blinded CT- scans. The data obtained from the three observers were compared to the actual management and were subjected to statistical analysis. Results: As the data was categorical and matched, the Mcnemars test was used to test the association between the management plan obtained from the radiographs and the management plan obtained from the CT scans, for each consultant. They were also compared with the actual management. The statistical analysis showed that there was no statistically significant association between the management decision obtained from the radiographs and the CT san, for all three observers. Radiograph and CT scan based management decisions also did not correlate with the actual management. Conclusion: The CT scan should only be done when a definite decision is made to operate on a patient, based on plain radiographs. Calcaneal fractures which are decided not to operate, based on X rays, should not have a CT scan as a routine as it provides no valuable additional information

Between June 1996 and April 2002, 56 patients underwent closed reduction and percutaneous fixation of calcaneal fractures. Of the 39 men and 17 woman, five were lost to follow-up. The patients’ mean age was 38 years (17 to 64). Four had bilateral procedures. Using the AOFAS Ankle and Hindfoot Scale (AHS) and Visual Analogue Pain Scale (VAPS), we assessed patients preoperatively and at 6 and 12-monthly intervals. Clinical examination was undertaken preoperatively and postoperatively at 2-week, 6-week, 3-month, 6-month and 12-monthly intervals. Except at two weeks, radiographs included weight-bearing axial and lateral views at all intervals. Follow-up was for a mean period of 42 months (12 to 72). The mean time to union was 10.2 weeks (8 to 14). The AHS improved from 34 preoperatively to 85 at the most recent follow-up. The VAPS improved from 9.1 preoperatively to 2.2 at three years. The satisfaction rate was 86%. Functional results depended on the quality of the reduction of the posterior facet and the severity of the initial injury. Complications included a 5% sural nerve injury and a 3% peroneal tendinopathy. No wound complications were encountered. In selected cases, closed reduction and internal fixation of calcaneal fractures may produce results similar to those of conventional open reduction and internal fixation, with fewer complications. This technique is best performed within 24 to 72 hours of injury

Background: The Calcaneus is the largest of the tarsal bones. 2% of all adult and 60 % of all tarsal fractures involve the Calcaneus. A true consensus regarding the management of these fractures still eludes orthopaedic surgeons. While operative treatment for displaced fractures has gained more acceptance in the last decade, surgical morbidity still remains high. Aim: A retrospective review of the early complications and radiological outcomes following open reduction and internal fixation of displaced calcaneal fractures in our unit over the last 15 months. Methods: A consecutive series of 33 patients who underwent surgical fixation of the Calcaneus was selected. Patient records, X rays and scans were reviewed. Mode and nature of injury, life style factors, surgical complications and Bohler’s angles were analysed. Results: 37 fractures in 33 patients underwent operative fixation. 81 % were male. Mean age at surgery was 37yrs (range19–59). 35 % were operated within 1 week of the injury and 13% after 2 weeks of injury. 43% were Sanders’ type III, 18% type II and 13% tuberosity avulsion fractures. 63% of patients had a reversed or zero Bohler’s angle. Mean post-op Bohler’s angle was 32 degrees. Overall complication rate was 32%, with a combined deep infection rate of 8%. All patients with infection were male, and 70% were smokers. 86% were above 40yrs of age (mean 47yrs). The deep infection rate for intra-articular fractures was 3% and for tuberosity avulsion fractures 40%. Majority of patients with wound complications had been operated within 7 days of injury. 4 patients had persisting pain requiring removal of metal work. Discussion: Our study highlights that there are significant risks associated with operative management of calcaneal fractures. Male patients over the age of 40yrs who are smokers seem to be at most risk of wound complications. Time to surgery or delay in surgery up to 2 weeks did not seem to have any adverse consequences. Complications increase with fracture complexity, and avulsion fractures have a high risk of wound breakdown. Near anatomical restoration of the articular surface is possible in most cases

The purpose of this study was to present the long team functional results after conservative treatment of intraarticular calcaneal fractures. Nine patients with 11 fractures (mean age at accident 52 years old) were reevaluated. Mean follow-up was 8 years (6–15). 5 fractures were tongue type, 5 were compression fractures and 1 with comminution according to Essex Lopresti classification. These patients were clinically and functionally evaluated with the Ankle-Hind foot scale (Kitaoka, 1994). They were submitted to radiographic testing (foot AP, ankle lateral, axial and medial axial views). Osteoarthritic (OA) changes, calcaneal dimensions (height, width) and Bohler’s – Gissane’s angles were recorded. According to Ankle Hind foot score (highest 100) our patients scored a mean 77 points (48–90). OA changes were recorded in 7 cases in the ankle joint and in all cases in taloscaphoid, calcanocuboid (severe in 8) and subtalar joints (severe in 5). We found width reduction in 6 patients and height reduction in 2, compared to the healthy side. Bohler’s angle was abnormal in 6 cases (−21°to 52°) while Gissane’s angle was abnormal in 9 (84° to 115°). Treatment of intraarticular calcaneal fractures is still controversial. Recent studies show a tendency for surgical treatment. In the present study a distinction between clinical and radiographic findings was made. Patients had satisfactory functional results although severe osteoarthritic changes were recorded

Introduction: The optimal treatment of intra-articular calcaneal fractures remains controversial. Material and Methods: Electronic databases were searched for randomised trials comparing interventions for treating patients with calcaneal fractures. Two reviewers independently assessed trial quality, using a 12-item scale, and extracted data. Where appropriate results were pooled. Results: Six trials met the inclusion criteria. Two reports reported on the same group of patients at differing follow-up intervals. All six included trials had methodological flaws. Another two trials are ongoing. Four trials (134 patients) compared open reduction and internal fixation (ORIF) with non-operative management. Pooled results showed no difference in residual pain (24/40 versus 24/42; OR 0.90, 95% CI 0.34 to 2.36), but a lower proportion of the operative group was unable to return to the same work (11/45 vs 23/45; OR 0.30, 95% CI 0.13 to 0.71), and was unable to wear the same shoes as before (12/52 vs 24/54; OR 0.37, 95% CI 0.17 to 0.84). One large-scale study showed that the outcomes (SF-36, visual analogue scale (VAS), Bohler’s angle) after non-operative treatment were not different to those after ORIF. ORIF gave superior results for return to work, return to normal activities and ability to wear the same shoes. The subtalar fusion rate was reduced after ORIF. Excluding patients receiving Workers’ Compensation, the outcomes were significantly better in some groups of surgically treated patients. One trial (23 patients), evaluated impulse compression therapy. At one year there was a mean difference of 1.40 pain VAS units (95% CI 0.02 to 2.82) in favour of the treated group. The impulse compression group had greater subtalar movement at three months, and patients returned to work three months earlier. Conclusions: The relatively poor quality of existing trials means that current evidence is only tentative. It remains unclear whether the possible advantages of surgery are worth its risks

Introduction. Considerable controversy exists with regard to the surgical management of displaced intra-articular calcaneal fractures. Protagonists for internal fixation would suggest there is sufficient evidence to expect better functional outcomes with surgery. However, this is not conclusive. Aim. To identify factors which improved outcome following surgery. Method. Between 1994–2000, 28 patients with 30 displaced intra-articular fractures of the calcaneum were treated with open reduction and internal fixation at our hospital (mean age 45 years). We reviewed 20 patients within the Shropshire region using four recognised hindfoot scoring systems. Patients were classified according to Sanders’ classification with pre-operative CT scans. The mechanism of injury and post-operative management were recorded. Clinical and radiographic assessments were also made. Results. Average follow-up was 3.6 years. The overall surgical results were comparable with similar studies based upon the Maryland Foot Score (30% excellent, 35% good, 30% fair, 5% poor). Seventy-five percent of our patients returned to work within six months at an average of five months. Three patients developed a superficial wound infection. Age, energy of injury, time to surgery, time spent in plaster and time to commencing physiotherapy had no significant bearing on functional outcome. However, early weightbearing at six weeks positively influenced outcome with all four scoring systems (p=0.01, 0.01, 0.02, 0.05) with a deterioration of outcome with delayed weightbearing. This was shown to be due to loss of subtalar joint mobility (r=−0.74, p=0.001). Conclusions. We propose that good results can be obtained from internal fixation of intra-articular calcaneal fractures with a high probability of early return to work. We recommend that patients be encouraged to weightbear at 6 weeks to optimise mobility at the subtalar joint

The purpose of the study was to perform an independent assessment of the results of open reduction and internal fixation (ORIF) on a selected group of displaced intra-articular calcaneal fractures from two centres. It still remains controversial whether to manage intraarticular calcaneal fractures conservatively or operatively with few long-term results. The identification of patients who may benefit from the procedure is still undecided. Fifty fractures in 46 patients with a defined significant displacement of an intra-articular fracture of the calcaneum underwent ORIF by one of the two senior authors. Mean age at operation was 46 years and mean follow-up was 44 months. 88% of the injuries were due to a fall from a height. 30% of the patients had contralateral foot/ankle injuries, and 20% of the patients developed a superficial wound infection. The infection rate was significantly higher in patients whose surgery was delayed more than 14 days. All patients were independently reviewed after a minimum two-year follow-up. A clinical, radiographic and subjective assessment of the outcome was made. The results were correlated to the original fracture type. The mean Atkins score was 88 (out of 100). Bilateral injuries fared worse. Heel pain at follow-up correlated with a poor score. Atkins scores over 90 occurred in 77% of Saunders Type II, 50% in Type III, and 43% in Type IV fractures. 94% returned to work at a mean of 10 months post-injury. Three patients have undergone a subtalar arthrodesis – two for persistent pain and one for a significant malunion. One patient required a flap but there have been no cases of chronic osteomyelitis. In patients with significantly displaced fractures, ORIF is a worthwhile procedure with 90% of patients satisfied and 94% returning to work. Gross articular comminution does not preclude a good/excellent result if hindfoot alignment is restored. ORIF after fourteen days should be avoided due to the high risk of infection

To evaluate the cost-effectiveness of operative versus non-operative management of displaced intra-articular calcaneal fractures (DIACFS), a model was constructed based on a randomized clinical trial. Model outputs were costs and quality-adjusted life years (QALYs). When a societal perspective was taken (i.e. productivity losses were included), operative management was less costly and more effective than non-operative care. Sensitivity analysis revealed that cost-effectiveness was highly dependent on the estimates of productivity losses. When productivity losses were excluded, the increase in cost of operative treatment was $2,700 for an incremental gain of .06 QALYs, giving an incremental cost-utility (CU) ratio of $44,000 per QALY gained. To evaluate the cost-effectiveness of operative versus non-operative management of displaced intra-articular calcaneal fractures (DIACFs). A decision tree was constructed to model the effect on costs and quality-adjusted life years (QALYs) of operative versus non-operative management for DIACFs. Complication rate, fusion rate, patient survival and utilities, and productivity losses were estimated from a recent prospective randomized control trial. Four-year costs were estimated from the center treating 73% of the patients in the trial. A societal perspective was used. Future costs and benefits were discounted at 5% and reported in 2002 Canadian Dollars. One-way and multi-way sensitivity analysis was performed on all variables using plausible ranges. When productivity losses were included, operative management was less costly ($13,000 saving) and had a gain of .06 QALYs (based on improvements in health related quality of life), making it the dominant strategy compared to non-operative treatment. The cost-effectiveness was most sensitive to the return to work estimates. When productivity losses were excluded, the increase in cost of operative treatment was $2,700 for a .06 QALY gain, giving an incremental cost-utility (CU) ratio of $44,000 per QALY gained. The treatment of the DIACF has long a source of uncertainty in orthopedic surgery. A recent prospective, randomized, trial concluded that operative management provided no improvement over non-operative care. The cost-effectiveness of operative management indicates that it is a moderately economically attractive treatment (a CU ratio of < $50,000). Further exploration of the impact of productivity losses is required. Funding: Dr. Brauer is supported by a grant from Alberta Heritage Foundation

Aims

This study aimed to establish the optimal fixation methods for calcaneal tuberosity avulsion fractures with different fragment thicknesses in a porcine model.

Displaced intra-articular fractures of the calcaneus need anatomic reduction of the joint surfaces and overall shape to restore function and minimize the risk of posttraumatic subtalar arthritis. The morbidity associated with extended approaches is a major concern. In the present study we compared the medium-term results after percutaneous reduction and screw fixation (PRSF) with that of open reduction and internal fixation (ORIF) for displaced fractures with less severe fracture patterns (Sanders type II). Material and Methods: In a matched cohort study from March 1998 to October 2004 the results of 36 patients treated either with PRSF or ORIF for displaced Sanders type II calcaneal fractures and Tscherne grade 1–2 closed soft tissue injury were reviewed. Each group contained 3 female and 15 male patients. Mean patient age was 40.1 years in the PRSF and 42.6 years in the ORIF group. PRSF was carried out percutaneously with small fragment (3.5 mm) screws under arthroscopic and fluoroscopic control. ORIF was performed with a lateral plate via an extended lateral approach. Early ROM exercises of the ankle and subtalar joints were initiated for all patients at the first postoperative day. Patients were mobilized with partial weight-bearing for 6–8 weeks postoperatively in their own shoes. Detailed follow-up with clinical and radiographic evaluation was obtained for all patients at a mean of 23 months postoperatively. Results: One patient (5.6%) from the ORIF group developed postoperative wound edge necrosis that responded well to conservative management with antiseptic dressings. In the PRSF group no complications were seen. Patients fully returned to work after 10.8 weeks in the PRSF group and 16.2 weeks in the ORIF group. Subjectively 17 of 18 patients (94%) in the PRSF group and 15 of 18 patients (83%) in the ORIF group rated their result as good to excellent at follow-up. The AOFAS Ankle Hindfoot Score averaged 93.8 for the PRSF group and 88.2 for the ORIF group (N. S.). The average Böhler angle improved from 13 to 25° in the PRSF group and from 10 to 26° in the ORIF group. Subtalar range of motion was significantly reduced in the ORIF group at the time of follow-up. Hindfoot eversion/inversion averaged 42.7° in the PRSF group and 33.6° in the ORIF group (p< 0.05). Conclusions: Regardless of the treatment option, patients with less severe displaced intrta-articular calcaneal fractures can expect good to excellent results after anatomic reduction of the subtalar joint. Percutaneous screw fixation leads to earlier rehabilitation and better subtalar motion than open reduction and internal fixation via an extended lateral approach. Percutaneous fixation of these fractures should be contemplated for these fractures provided adequate control over the joint reduction either with subtalar arthroscopy or high -resolution (3D) fluoroscopy

Arthrodesis of both the ankle and the hindfoot has been discussed in the literature since the early part of the last century. Techniques have been modified substantially since these early discussions, though complications remain a frustrating element in patient management. Early procedures relied on molded plaster casts to hold fixation in corrected positions. Successful outcomes were hampered by loss of reduction in these casts and subsequent malunions. In addition, motion within these casts lead to a high rate of nonunion between the opposed bony surfaces. The era of internal fixation allowed compression across arthrodesis sites, enhancing union but creating a host of technical errors leading to unsatisfying results. Malunion is also seen in post-traumatic situations. In particular, non-operative management of calcaneus fracture (or other hindfoot fractures) leads to not only arthritis of the involved joint surfaces, but malunion complicating successful fusion. Fusion in-situ leads to a high level of patient dissatisfaction, leading surgeons to challenging deformity correction while trying to achieve successful arthrodesis in compromised joints. This lecture will focus on two types of malunion, one iatrogenic, one acquired. Revision triple arthrodesis (iatrogenic) can range from simple to challenging. A variety of studies document patient dissatisfaction following correction via this technique, ranging from Graves and Mann (1993) where the highest dissatisfaction rate was in highest in valgus malunion, to Sangeorzan and Hansen (1993), who found a 9% failure rate, most with varus malunion. The precarious balance required to create a plantigrade foot via triple arthrodesis with pre-existing deformity leaves even the most skilled surgeon challenged. As such, this component of the lecture will focus on recognition and correction of malunion based on a structured algorithmic approach we first presented in 1997. This algorithm is based on recognition of the apex of the deformity, and creating osteotomies to achieve balance. We reviewed 28 patients who returned for follow-up examination who received treatment through this algorithm and found a statistically significant improvement in pre- and postoperative AOFAS ankle/hindfoot score, from an average of 31 points preoperatively to 59 postoperatively (p<0.01). All patients united, and all stated they would undergo the revision procedure again. Comparisons of pre- and postoperative shoe wear modification demonstrated a statistically significant improvement (p=0.01). Preoperatively, 20 patients required restrictive devices such as ankle foot orthoses and orthopaedic shoes. Postoperatively, only 1 patient required such a restrictive device. In fact, 17 patients required no modifications to their shoe wear at all. The second component to this lecture will assess acquired hindfoot deformity, from malunion created by calcaneus fractures. A 2005 JBJS study by Brauer, et.al. found operative management resulted in a lower rate of subtalar arthrodesis with a shorter time off work compared to non-operative management. Removing the expense of time off work still netted a $2800 savings for operative management over non-operative management. Sanders echoed these thoughts in a JBJS 2006 paper, suggesting patients with displaced intra-articular calcaneal fractures may benefit from acute operative treatment given the difficulty encountered in restoring the calcaneal height and the talo-calcaneal relationship in symptomatic calcaneal fracture malunion. Thus, with these challenges in mind, the goal of this component of the lecture is to introduce methods to achieve balance and union with calcaneus fracture malunion. Vertically oriented multiplanar calcaneal osteotomy may assist the surgeon in avoiding the higher non-union rate associated with bone-block arthrodesis procedures. In this vein, the challenges associated with bone block subtalar arthrodesis will be explored

Background. This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs. Methods. Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans. Results. In 11 patients, a small bony fleck lies within the superior peroneal retinaculum and contiguous periosteum, which are stripped off the lateral fibula (Class II lesions). Tendons dislocate into the subperiosteal pouch thus formed, resembling Class I lesions without associated bony avulsion. Treatment for Class II is same as for Class I injuries. In 8 patients with big bony fleck, tendons dislocate into the fracture site and SPR is intact (Class III lesions). Surgical approach for tendon relocation and bone fixation differs. In particular, the intact attachment of the SPR on the bony fleck must not be incised. The healing process of neglected Class III lesions resembles a groove deepening procedure, representing an attempt to form a stable platform for the dislocated tendons. A neglected Class II lesion resembles a neglected Class I lesion. In Class IV lesions, observed in 5 patients with 2-part calcaneal fracture/dislocation, SPR remains intact and peroneal tendons are not dislocated. The invariably large fleck results from the displacing lateral calcaneal fragment abutting against the fibula, whereas the dislocating tendons cause the bony avulsions in Classes II and III. Conclusions. Due to pathoanatomical differences, surgical approach and natural history of neglected lesions differ depending on size of the bony fleck. The SPR must not be incised in case of big Class III flecks. Beware of false negatives when probing the peroneal tendons intra-operatively in Class III and IV lesions

Since 2008 the improvised explosive device has been responsible for a significant proportion of injuries sustained whilst on operational duty in Afghanistan. Vehicles have been developed and adapted to offer maximal protection to service personnel. As a result of the decrease in mortality, there has been an increase in the severity of injuries to the lower limb. Hind-foot injuries are a difficult cohort of injuries to treat successfully. Those that are amenable to reconstruction carry a significant morbidity, which may result in either early or delayed amputation. There has been a new injury pattern to the lower limb, not previously described in the medical literature. This pattern consists of a displaced intra-articular calcaneal fracture, distal third tibial fracture and midfoot injury within the same limb. We believe the combination of the three injuries form the “unhappy triad of the ankle”. Each of the injuries is individually reconstructable, but the combination of all three primary amputation should be considered as part of the surgical options
