This review article on the current management for calcaneal fractures discusses the advantages and disadvantages of different treatment options including the problems encountered. Controversies are described and the evidence reviewed. The management of some types of displaced intra-articular calcaneal fractures remains contentious; is there a preferred stabilisation method for each type of calcaneal fracture? How constant is the "constant fragment" in an intra-articular calcaneal fracture and wh ...[more]

Project description:BackgroundOperative treatment of calcaneal fractures using the extensile lateral approach is associated with high rates of soft tissue complications. In the past years, there has been a trend toward less invasive surgical approaches. Percutaneous and arthroscopically assisted calcaneal osteosynthesis (PACO) combines the advantages of visualization of the posterior facet of the subtalar joint with a minimally invasive approach.MethodsWe conducted a follow-up of 25 patients with 26 calcaneal fractures (Sanders II and III), treated with PACO with a minimum follow-up of 12 months. The median age was 44 years (range, 21-72) and the follow-up period 15 months (12-33). Our clinical outcomes were the Manchester-Oxford Foot Questionnaire (MOxFQ), the Calcaneus Fracture Scoring System (CFSS), the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score, the Short-Form-36 (SF-36), the visual analog scale (VAS) for pain, and the number of complications. Radiographs on follow-up were obtained to evaluate the reduction of the fractures as well as osteoarthritis of the subtalar joint.ResultsThe median MOxFQ score was 26.6 (0-76.6), the CFSS score 85 (26-100), and the AOFAS score 85 (50-100). The VAS pain score was 0 (0-5.7) at rest and 4.1 (0-8.2) during activity. The Böhler angle improved from a mean (SD) of 3.5 (12.3) degrees preoperatively to 27.7 (10.5) degrees postoperatively. The follow-up radiographs showed subsidence of the fractures and a Böhler angle of 20.3 (12.9) degrees. There were no wound-healing complications. Two patients had additional surgery with screw removal due to prominent hardware.ConclusionOur results suggest that PACO gives good clinical outcomes and a low risk of complications in selected calcaneal fractures. Prospective long-term studies will be necessary to better document the potential advantages and limitations of this operating technique.Level of evidenceLevel IV, retrospective case series.

Project description:BackgroundCalcaneal fractures are the most common tarsal bone fracture, and are often accompanied by heel pain, local swelling, tenderness, and inability to walk or stand. Surgical intervention results in better reconstruction of the calcaneal anatomy and reduces future complications; however, the optimal incision approach is still controversial. The incision is exposed better with extensile lateral approach (ELA), while the sinus tarsi approach (STA) causes fewer complications. The purpose of this meta-analysis is to compare the outcomes of STA and ELA.Materials and methodsPublished trials comparing ELA and STA in calcaneal fractures were included in our analysis. The quality of each study was assessed using the revised Jadad scale and the Newcastle-Ottawa scale. Two researchers (CP and BY) independently extracted data from all selected studies. Fixed- or random-effects models with mean differences and odds ratios were used to pool the continuous and dichotomous variables to determine the heterogeneity of the included studies.ResultsCalcaneal height and calcaneal width had high heterogeneity. Results showed that the incidence of incision complications in STA was lower than that in ELA (P < .001). There was high heterogeneity in operative time (I2 = 97%), length of hospital stay (I2 = 98%), Böhler angle (I2 = 80%), Gissane angle (I2 = 98%), and American Orthopaedic Foot & Ankle Society scores (I2 = 73%). No source of heterogeneity was found by sensitivity analysis, subgroup analysis, or regression analysis, and the random-effects model was used. STA operative time was significantly shorter than ELA (P < .001). Length of hospital stay after STA was significantly shorter than after ELA (P = .002). There was no statistical difference in the Böhler and Gissane angles between STA and ELA. Postoperative American Orthopaedic Foot & Ankle Society scores after STA were higher than after ELA (P = .01).ConclusionsResults show that, compared with ELA, STA is superior for treating calcaneal fractures due to anatomical reduction of the calcaneus, reduction of incision complications incidence, and shortened operative time and postoperative stay.

Project description:The calcaneal beak fracture is a rare avulsion fracture of the tuber calcanei characterized by a solid bony fragment at the Achilles tendon insertion. Treatment usually requires osteosynthesis. However, lack of biomechanical understanding of the ideal fixation technique persists. A beak fracture was simulated in synthetic bones and assigned to five different groups of fixation: A) 6.5-mm partial threaded cannulated screws, B) 4.0-mm partial threaded cannulated screws, C) 5.0-mm headless cannulated compression screws, D) 2.3-mm locking plate, and E) 2.8-mm locking plate. Different traction force levels were applied through an Achilles tendon surrogate in a material-testing machine on all stabilized synthetic bones. Outcome measures were peak-to-peak displacement, total displacement, plastic deformation, stiffness, visual-fracture-line displacement, and mode of implant failure. The 2.3- and 2.8-mm plating groups showed a high drop-out rate at 100 N tension force and failed under higher tension levels of 200 N. The fracture fixation using 4.0-mm partial threaded screws showed a significantly higher repair strength and was able to withhold cyclic loading up to 300 N. The lowest peak-to-peak displacement and the highest load-to-failure and stiffness were provided by fracture fixation using 6.5-mm partial threaded cannulated screws or 5.0-mm headless cannulated compression screws. As anticipated, large 6.5-mm screw diameters provide the best biomechanical fixation. Surprisingly, the 5.0-mm headless cannulated compression screws yield reliable stability despite the absent screw head and washer. When such large screws cannot be applied, 4.0-mm screws also allow reasonable fixation strength. Plate fixation should be implemented with precaution and in combination with a restrictive postoperative motion protocol. Finally, clinical cases about the surgical application and recovery are included.

Project description:IntroductionA retrospective cohort study demonstrated that, in comparison with open reduction and internal fixation through an extensile lateral approach, our percutaneous technique for reduction and internal fixation of displaced intra-articular calcaneal fractures decreases the rate of complications and achieves and maintains extra-articular fracture reductions just as well.Step 1 patient positioning and imagingPosition the patient correctly to obtain excellent fluoroscopic views, which are key to the procedure.Step 2 fracture reductionThe techniques for reducing and fixing joint depression and tongue-type calcaneal fractures differ and will be described separately.Step 3 screw fixationIdentify screw entry points and paths using fluoroscopic images, and confirm the final positions with c-arm imaging.Step 4 postoperative managementApply a splint; then obtain postoperative images to confirm fracture reduction and screw placement.Results & preop/postop imagesThe results of percutaneous reduction of displaced intra-articular calcaneal fractures in seventy-nine patients with a total of eighty-three fractures were compared with those obtained by another surgeon using the extensile lateral approach.What to watch forIndicationsContraindicationsPitfalls & Challenges.

Project description:BackgroundIntra-articular calcaneal fractures are complex injuries, and CT imaging has become the standard imaging in the preoperative assessment. Most classifications of these fractures are CT-based but have been associated with limited interobserver agreement. Three-dimensional imaging has become widely available and may give a better perspective but often with 1 image only. There is not much evidence of the added value of this imaging, compared with the CT imaging.MethodsEight experienced trauma surgeons assessed 28 different intra-articular calcaneal fractures, on conventional radiology (CR), CT, and 3-D imaging. All had extensive experience in the diagnosis and treatment of this difficult injury. The main questions concerned Sanders classification, the severity of the injury and the difficulty of the operative procedure, choice of approach, and choice of procedure.ResultsThe classical 2-D CT imaging of the fractures were associated with a higher Sanders classification ranking, compared with the 3-D imaging scores. However, the interobserver agreement, as measured by the Fleiss kappa, was low for all 3 imaging modalities. We found more frequent Sanders III and IV classifications with CT scan imaging compared with 3-D imaging or CR. The scores obtained after assessing 3-D imaging were also not statistically significantly different from the scores of a consensus achieved by 2 authors and based on the 3 imaging modalities and the perioperative diagnosis.ConclusionThe 3-D imaging may result in a more realistic view, reducing the frequency of classifying Sanders III fractures than with the 2-D CT imaging series. 3-D imaging may be more reliable than CT in the planning of operative treatment of displaced intra-articular calcaneal fractures.Level of evidenceLevel III.

Project description:ObjectiveThe aim of this study was to introduce a novel method of simultaneous in situ decompression of lateral calcaneal bulge and subtalar arthrodesis via a single incision for malunion after calcaneal fractures and evaluate the feasibility of this method.MethodsFrom September 2010 to October 2011, six patients (five males and one female) with malunion and delayed heel pain after conservative treatment of displaced intra-articular calcaneal fractures were included in our study. The mean age of the six patients was 32.9 years (range, 25-71 years). Patients were treated with this novel technique at our department and the functional outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scores during follow-up. Information of the six patients including surgical data and pre/postoperative function scores were retrospectively analyzed using SPSS 19.0 statistical software.ResultsThe average operation time between wire insertion and incision suture was 42.2 ± 11.5 min (range, 25-56 min). The blood loss in all patients was all less than 50 ml each. The average fluoroscopy time was 25.7 ± 11.6 s (range, 11-43 s). No wound-related and other short-term complications were recorded. Six patients who were included in our study were followed for an average period of 66.2 ± 4.7 months (range, 60-73 months). There was no patient lost to follow up. Heel pain was observed to be greatly improved preoperatively in all of the six patients. All patients restored to normal activity of life after surgery. Radiological evidence of fusion was observed in five patients. The average fusion time of these five patients was 3.5 months (range, 2-4 months). The remaining one failed to achieve fusion and the hardware removal was performed due to screw tail irritation. This patient was satisfied with the final outcomes subjectively after removal of hardware. The mean AOFAS scores at 24 months postoperative were 82.0 ± 7.0, which was greatly improved compared to preoperative (44.8 ± 10.7) (P < 0.05). The preoperative VAS pain scores were decreased from 5.8 ± 1.5 to 2.6 ± 1.4 at 24 months postoperative (P < 0.05) and slightly decreased to 2.0 ± 1.7 at 48 months postoperative (P < 0.05). No surgery-related complications were observed in any of the patients.ConclusionsThe novel technique can effectively relieve the heel pain, prompt functional recovery, decrease the incidence of complications, simplify the surgical procedure, and shorten the learning curve. Therefore, the technique is a feasible and worthwhile alternative in treating malunion after calcaneal fractures.

Project description:BackgroundThis study aimed to evaluate tongue-type calcaneal fractures using three-dimensional (3D) computed tomography (CT) mapping method.MethodsA consecutive series of 136 tongue-type calcaneal fractures was used. CT data were used to reconstruct and reposition the 3D calcaneus body. E-3D Medical 18.01 software was used to superimpose the fractured calcaneal entity on the template, and the fracture line was drawn on the template. Finally, the heatmap was obtained using the fracture statistical analysis function. At the same time, the distribution of fracture lines in the anterior part of the calcaneus (APC) was recorded. Cases were divided into the following 3 subtypes according to the distribution of the tongue-type fracture lines of the calcaneal body: medial-lateral (Group A), upper-lateral (Group B), and upper-lateral-medial (Group C).ResultsThere were 68 cases in Group A, 48 cases in Group B, and 20 cases in Group C. Based on subtype, the characteristic fracture map of Groups A, B and C was constructed. The APC was evenly divided into zones A, B, and C from lateral to medial. In Group A, the most common types involve APC were Type AC (24, 35.3%) and Type A (11, 16.2%). In Group B, the most common types were Type AC (20, 41.7%), Type AB (8, 16.7%) and Type C (8, 16.7%). In Group C, the most common types were Type AC (8, 40.0%) and Type A (5, 25.0%).ConclusionsThis study investigates the distribution characteristics of fracture lines in subgroups of tongue-type calcaneal fractures for the first time. The results can help doctors improve their understanding of tongue-type calcaneal fractures, optimize internal fixation design, and provide a standard model for biomechanical experiments.

Project description:PurposeSurgically treated calcaneal fractures have a high risk of postoperative wound healing complications and a prolonged length of hospital stay (LOS). The aim of this study was to identify predictor variables of impaired wound healing (IWH) and LOS in surgically treated patients with isolated calcaneal fractures.MethodsThis retrospective cohort study analyzed data on patients aged 18 years or older who were admitted to a level I trauma center with isolated calcaneal fractures between 2008 and 2018. Multivariable regression models were used to identify predictor variables.ResultsIn total, 89 patients (age: 45.4 years; SD: 15.1) were included. In 68 of these patients, low-profile locking plate osteosynthesis was performed, and a minimally invasive approach (MIA) (percutaneous single screws/K-wire or low-profile locking plating via a sinus tarsi approach) was applied in 21 patients. Multivariable regression analysis revealed that a higher preoperative Böhler's angle (β = - 0.16 days/degree, 95% CI [- 0.25, - 0.08], p = 0.004) and MIA (β = - 5.04 days, 95% CI [- 8.52, - 1.56], p = 0.002) reduced the LOS. A longer time-to-surgery (β = 1.04 days/days, 95% CI [0.66, 1.42] p = 0.001) and IWH increased the LOS (β = 7.80 days, 95% CI [4.48, 11.12], p = 0.008). In a subsequent multivariable regression analysis, two variables, open fractures (OR: 14.6, 95% CI [1.19, 180.2], p = 0.030) and overweight (BMI > 24) (OR: 3.65, 95% CI [1.11, 12.00], p = 0.019), increased the risk of IWH.ConclusionAdvanced treatment algorithms for open fractures are needed to reduce the risk of IWH.

Project description:Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet. However, this technique has the risk of complications such as wound necrosis and sural nerve injury. Various minimally invasive approaches, such as sinus tarsi approach, limited posterior approach, and percutaneous approach, have been introduced to reduce possible complications. This study was prospectively performed to evaluate the results of the sinus tarsi approach for Sanders Type 2 calcaneal fractures using postoperative computed tomography (CT).Between October 2012 and December 2013, 20 Sanders Type 2 calcaneal fractures were consecutively treated using a sinus tarsi approach and checked using CT preoperatively, immediately postoperatively, and at 12 months after surgery. Clinical evaluations were performed using the visual analog scale (VAS) and the ankle-hindfoot score developed by the American Orthopaedic Foot and Ankle Society (AOFAS). Radiographic evaluations were performed using calcaneus lateral and axial radiographs, hindfoot alignment radiograph, and CT. Changes in Böhler's angles and calcaneal widths were evaluated both preoperatively and at last followup. Reduction of the posterior facet was graded according to articular step, defect, and angulation of the posterior facet in CT.VAS and AOFAS scores were significantly improved at 1 year after surgery but did not improve further. Böhler's angles and calcaneal widths were significantly improved after surgery. Böhler's angle was significantly smaller at the last followup than immediately after surgery, whereas calcaneal width was maintained. Reduction of the posterior facet was graded excellent in five feet (25%), good in ten (50%), and fair in five (25%) on immediately postoperative CT. Two feet (10%) had transient sural nerve injury which resolved within 3 months. Five feet (20%) had subfibular pain due to a prominent screw heads.Surgical management using a sinus tarsi approach produced good clinical and radiographic results and low wound complications for Sanders type 2 calcaneal fractures. It is important to have stable fixation and to achieve sufficient reduction of calcaneal width for the prevention of loss of reduction and lateral subfibular impingement.
