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

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

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

Aims. This study aimed to establish the optimal fixation methods for calcaneal tuberosity avulsion fractures with different fragment thicknesses in a porcine model. Methods. A total of 36 porcine calcanea were sawed to create simple avulsion fractures with three different fragment thicknesses (5, 10, and 15 mm). They were randomly fixed with either two suture anchors or one headless screw. Load-to-failure and cyclic loading tension tests were performed for the biomechanical analysis. Results. This biomechanical study predicts that headless screw fixation is a better option if fragment thickness is over 15 mm in terms of the comparable peak failure load to suture anchor fixation (headless screw: 432.55 N (SD 62.25); suture anchor: 446.58 N (SD 84.97)), and less fracture fragment displacement after cyclic loading (headless screw: 3.94 N (SD 1.76); suture anchor: 8.68 N (SD 1.84)). Given that the fragment thickness is less than 10 mm, suture anchor fixation is a safer option. Conclusion. Fracture fragment thickness helps in making the decision of either using headless screw or suture anchor fixation in treating calcaneal tuberosity avulsion fracture, based on the regression models of our study.

Background. The treatment of chronic calcaneal osteomyelitis is a challenging and increasing problem because of the high prevalence of diabetes mellitus and operative fixation of heel fractures. In 1931, Gaenslen reported treatment of hematogenous calcaneal osteomyelitis by surgical excision through a midline, sagittal plantar incision. We have refined this approach to allow successful healing and early mobilization in a modern series of complex patients with hematogenous, diabetic, and postsurgical osteomyelitis. Methods. Twenty-eight patients (mean age 54.6 years, range 20–94) with Cierny-Mader stage IIIB chronic osteomyelitis were treated with sagittal incision and calcaneal osteotomy, excision of infected bone, and wound closure. All patients received antibiotics for at least 6 weeks, and bone defects were filled with an antibiotic carrier in 20 patients. Patients were followed for a mean of 31 months (SD 25.4). Primary outcome measures were recurrence of calcaneal osteomyelitis and below-knee amputation. Secondary outcome measures included 30-day postoperative mortality and complications, duration of postoperative inpatient stay, footwear adaptions, mobility, and use of walking aids. Results. All 28 patients had failed previous medical and surgical treatment. Eighteen patients (64%) had significant comorbidities. The commonest causes of infection were diabetes ± ulceration (11 patients), fracture-related infection (4 patients), pressure ulceration, hematogenous spread, and penetrating soft tissue trauma. The overall recurrence rate of calcaneal osteomyelitis was 18% (5 patients) over the follow-up period, of which 2 patients (7%) required a below-knee amputation. Eighteen patients (64%) had a foot that comfortably fitted into a normal shoe with a custom insole. A further 6 patients (21%) required a custom-made shoe, and only 3 patients required a custom-made boot. Conclusion. Our results show that a repurposed Gaenslen calcanectomy is simple, safe, and effective in treating this difficult condition in a patient group with significant local and systemic comorbidities

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

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

Background. Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below knee amputation; particularly in cases of severe soft tissue destruction. Aim. Assess the outcomes of combined ortho-plastics treatment of complex calcaneal osteomyelitis. Method. A retrospective review was performed of all patients who underwent combined single stage ortho-plastics treatment of calcaneal osteomyelitis (2008–2022). Primary outcome measures were osteomyelitis recurrence and BKA. Secondary outcome measures included flap failure, operative time, complications, length of stay. Results. 33 patients (16 female, 17 male, mean age = 54.4 years) underwent combined ortho-plastics surgical treatment for BACH “complex” calcaneal osteomyelitis with a median follow-up of 31 months (s.d. 24.3). 20 received a local flap, 13 received a free flap. Fracture-related infection (39%) and diabetic ulceration (33%) were the commonest causes. 54% of patients had already undergone at least one operation elsewhere. There were seven cases of recurrent osteomyelitis (21%); all in the local flap group. One patient required a BKA (3%). Recurrence was associated with increased mortality risk (OR 18.8 (95% CI 1.5–227.8), p=0.004) and reduced likelihood of walking independently (OR 0.14 (95% CI 0.02–0.86), p=0.042). Local flap reconstruction (OR 15 (95% CI 0.8–289.6), p=0.027) and peripheral vascular disease (OR 39.7 (95% CI 1.7–905.6), p=0.006) were associated with increased recurrence risk. Free flap reconstruction took significantly longer intra-operatively than local flaps (443 vs 174 minutes, p<0.001), but without significant differences in length of stay or frequency of out-patient appointments. Conclusions. Single stage ortho-plastic management was associated with 79% eradication of infection and 3% amputation in this complex and co-morbid patient group. Risk factors for failure were peripheral vascular disease and local flap reconstruction. Whilst good outcomes can be achieved, this treatment requires high levels of in-patient and out-patient care

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

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. 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

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

Aim. Calcaneal osteomyelitis is an uncommon and challenging condition. In this systemic review we aim to analyse the concomitant use of bone debridement and soft tissue management for patients diagnosed with calcaneal osteomyelitis. Method. A complete computerised and comprehensive literature search of Pubmed and Cochrane database was undertaken from January 2000 to October 2018. During the review, studies were screened for information about the surgical and antimicrobial treatment, the complications, the reinfection rate and the functional outcome of patients with calcaneal osteomyelitis. Results. Of the 20 studies included, seven (35%) described bone treatment only, six (30%) soft tissue treatment only, five (25%) soft tissue and bone treatment, and two (10%) focused on prognostic factors and differences in outcomes between diabetic and non-diabetic patients. In the studies with bone treatment only, infection recurrence ranged from 0 to 35% and the amputation rate from 0 to 29%. If soft tissue coverage was also needed, both the reinfection rate and amputation rate ranged from 0 to 24%. Studies presenting the functional status showed preservation or even improvement of the preoperative ambulatory status. Conclusions. Calcaneal osteomyelitis is difficult to treat. A multidisciplinary approach involving orthopaedic surgeons, plastic surgeons and infectious disease physicians is necessary for treatment success. Based on the localisation and size of the bone and soft tissue defect, decision for surgical treatment should be made

Introduction:. Open reduction and internal fixation of displaced intra-articular calcaneal fractures is susceptible to a high incidence of wound complications. Displaced fractures create abnormal contact characteristics at the subtalar joint, resulting in poor functional outcome and arthritis. We present the functional outcomes of 32 fractures (Sanders 2 and 3) at an average follow up of two years. Methods:. Over a 57 month period, 32 fractures (29 patients) underwent this technique in a London level 1 trauma centre. Open fractures were excluded. The previously described technique with sinus tarsi portals was used. Pre and post-operative radiographs and functional outcomes were assessed. Results:. Our patient cohort consisted of 20 male (23 fractures) and 9 female patients. Classification via the Sanders system revealed 37% 2A, 9% 2B, 41% 3AB, 9% 3AC and 3% 3BC. Mean follow up period was 24,2 months (range 5–57). All patients were operated on within 7 days of injury. Average inpatient stay was 1.9 days. 1 patient sustained a port site infection which was managed conservatively, while screws were removed from 2 patients. We had no cases of deep infections. The Bohler's angle increased from 10 to 29 degrees post operatively. Mean modified AOFAS scores (maximum score 60) was 40.3 (11–60), average VAS was 29.8 mm and CFS was 78.1. Importantly the majority of patients returned to their pre injury employment. Conclusion:. PACO is a demanding technique with an associated learning curve. However, our series shows that it is a safe and reproducible technique for significantly displaced intra-articular fractures. Post operative results are very encouraging with high levels of patient satisfaction and return to pre injury employment and activities. In addition it is a more cost effective treatment option as it is associated with minimal wound complications and a reduced hospital stay

Chronic calcaneal osteomyelitis is a rare and not usually part of the initial differential diagnosis of pseudotumoral calcaneal lesions. Presentation of surgical and functional outcomes of a case of a total calcanectomy. This can be seen as a foot rescue alternative in patients with chronic calcaneal osteomyelitis. We present the case of a 60 year- old patient with complaints of diffuse and intermittent pain in the left heel with 3 years of evolution. Radiographically, lytic lesion image sclerotic edges that covers the entire calcaneus, with preservation of cortical. MRI shows holo-calcaneal lesions compatible with tumor, infectious or inflammatory lesion. A biopsy is inconclusive. Negative microbiology results. Regular analytical study. It was decided to conduct a total calcanectomy. Procedure took place without complications. Patient still skin healing phase, without any pain complaint. It presents iconographic material made if and procedure. The total calcanectomy is an alternative procedure to transtibial amputation in patients with chronic calcaneal osteomyelitis

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.

Objectives. The aim of the current study was to assess whether calcaneal broadband ultrasound attenuation (BUA) can predict whole body and regional dual-energy x-ray absorptiometry (DXA)-derived bone mass in healthy, Australian children and adolescents at different stages of maturity. Methods. A total of 389 boys and girls across a wide age range (four to 18 years) volunteered to participate. The estimated age of peak height velocity (APHV) was used to classify children into pre-, peri-, and post-APHV groups. BUA was measured at the non-dominant heel with quantitative ultrasonometry (QUS) (Lunar Achilles Insight, GE), while bone mineral density (BMD) and bone mineral content (BMC) were examined at the femoral neck, lumbar spine and whole body (DXA, XR-800, Norland). Associations between BUA and DXA-derived measures were examined with Pearson correlations and linear regression. Participants were additionally ranked in quartiles for QUS and DXA measures in order to determine agreement in rankings. Results. For the whole sample, BUA predicted 29% of the study population variance in whole body BMC and BMD, 23% to 24% of the study population variance in lumbar spine BMC and BMD, and 21% to 24% of the variance in femoral neck BMC and BMD (p < 0.001). BUA predictions were strongest for the most mature participants (pre-APHV R. 2. = 0.03 to 0.19; peri-APHV R. 2. = 0.05 to 0.17; post-APHV R. 2. = 0.18 to 0.28) and marginally stronger for girls (R. 2. = 0.25-0.32, p < 0.001) than for boys (R. 2. = 0.21-0.27, p < 0.001). Agreement in quartile rankings between QUS and DXA measures of bone mass was generally poor (27.3% to 38.2%). Conclusion. Calcaneal BUA has a weak to moderate relationship with DXA measurements of bone mass in children, and has a tendency to misclassify children on the basis of quartile rankings. Cite this article: B.

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
