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

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.

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

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

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.

Objectives

The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function.

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

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.

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
