ABSTRACT

Cellular debris resulting from large trauma might overwhelm the scavenger mechanisms and lead to autoimmune reactions. We analysed whether a major well-defined trauma in humans induces laboratory signs of transient autoimmunity in the months after the insult. We included 50 patients with pertrochanteric femur fracture undergoing intramedullary nail osteosynthesis in a prospective cohort study and followed them at 3-4 days, 6 weeks, 12 weeks and 12 months postoperatively. By standard techniques, we assessed levels of total immunoglobulins, anti-nuclear antibodies (ANA), anti-cardiolipin antibodies, anti-dsDNA antibodies and anti-C1q antibodies, as well as antibodies against cytomegalovirus (CMV) as a control. Blood leukocyte differential and lymphocyte subpopulations were determined at baseline and in the first two postoperative samples. The mean age of the patients reached 80.1 years, and 23 (46%) completed all visits. Serum concentrations of total IgG, IgM and IgA increased at all follow-up time points. The ANA fluorescence light intensity units increased at 12 weeks and 12 months postoperatively (p < 0.0001), but the proportion of ANA-positive patients did not change (35%). The values of anti-C1q mildly increased at all follow-up visits, but not the ratio to total IgG. Anti-dsDNA remained negative in all patients, and anti-cardiolipin IgG/IgM antibodies did not change. Anti-CMV IgG antibodies increased significantly at all follow-up visits, without change in the ratio to total IgG. Flow cytometry showed an increased proportion of B-cells 3-4 days postoperatively. In conclusion, major musculoskeletal trauma in elderly patients induces a generalized non-specific increase in immunoglobulin production without laboratory signs for enhanced systemic autoimmunity.

ABSTRACT

A judicious, well-planned bone and soft tissue debridement remains one of the cornerstones of state-of-the-art treatment of fracture-related infection (FRI). Meticulous surgical excision of all non-viable tissue can, however, lead to the creation of large soft tissue defects. The management of these defects is complex and numerous factors need to be considered when selecting the most appropriate approach. This narrative review summarizes the current evidence with respect to soft tissue management in patients diagnosed with FRI. Specifically we discuss the optimal timing for tissue closure following debridement in cases of FRI, the need for negative microbiological culture results from the surgical site as a prerequisite for definitive wound closure, the optimal type of flap in case of large soft tissue defects caused by FRI and the role of negative pressure wound therapy (NPWT) in FRI. Finally, recommendations are made with regard to soft tissue management in FRI that should be useful for clinicians in daily clinical practice.Level of evidence Level V.

ABSTRACT

BACKGROUND: Pelvic fractures in older patients are associated with relevant morbidity and mortality. Both might be determined by fracture morphology and/or patient characteristics. The aim of this project is to investigate the prognostic value of specific fracture characteristics with respect to overall survival and to compare it with an established classification system. METHODS: Retrospective analysis of patients ≥ 60 years, treated conservatively for a CT-scan verified, low-energy pelvic ring fracture between August 2006 and December 2018. Survival data was available from patients' charts and cantonal or national registries. The prognostic value of fracture characteristic describing the anterior and posterior involvement of the pelvic ring was investigated. This analysis was repeated after patients were stratified into a high-risk vs a low-risk group according to patient characteristic (age, gender, comorbidities, mobility, living situation). This allowed to assess the impact of the different fracture morphologies on mortality in fit vs. frail senior patients separately. RESULTS: Overall, 428 patients (83.4% female) with a mean age of 83.7 years were included. Two thirds of patients were still living in their home and mobile without walking aid at baseline. In-hospital mortality was 0.7%, overall, one-year mortality 16.9%. An independent and significant association of age, gender and comorbidities to overall survival was found. Further, the occurrence of a horizontal sacral fracture as well as a ventral comminution or dislocation was associated with an increased mortality. The effect of a horizontal sacral fracture was more accentuated in low-risk patients while the ventral fracture components showed a larger effect on survival in high-risk patients. CONCLUSION: Specific fracture characteristics may indicate a higher risk of mortality in conservatively treated patients with a low-energy pelvic ring fracture. Hence, they should be taken into account in future treatment algorithms and decisions on patient management.

ABSTRACT

INTRODUCTION: Pelvic ring fractures in the elderly are often caused by minor trauma. Treatment of these patients is currently based on fracture classification, clinical course, and ability to mobilize. Our aim was to identify morphological fracture characteristics with potential prognostic relevance and evaluate their association with clinical decision making and outcome, as well as their interobserver reliability. METHODS: Five fracture characteristics were investigated as potential variables: 1. Extent of the dorsal pelvic ring fracture (absent, unilateral, bilateral); 2. Extent of the ventral pelvic ring fracture (absent, unilateral, bilateral); 3. Presence of a horizontal sacral fracture; 4. Ventral dislocation; 5. Ventral comminution. These characteristics were assessed retrospectively in a series of 548 patients. The association of their presence with the decision to perform surgery, failure of conservative treatment and the length of hospital stay (LOS) was determined. Further, the inter-observer reliability for the specific characteristics was calculated and the relation with survival assessed. RESULTS: Four of the five evaluated characteristics showed an association with clinical decision making and patient management. In particular the extent of the dorsal fractures (absent vs. unilateral vs. bilateral) (OR = 7.0; p < 00.1) and the presence of ventral comminution/dislocation (OR = 2.4; p = 0.004) were independent factors for the decision to perform surgery. Both the extent of the dorsal fracture (OR = 1.8; p < 0.001) and the presence of ventral dislocation (OR = 1.7; p = 0.003) were independently associated with a prolonged overall LOS. The inter-observer agreement for the fracture characteristics ranged from moderate to substantial. A relevant association with increased mortality was shown for horizontal sacral and comminuted ventral fractures with hazard ratios (HR) of 1.7 (95% CI: 1.1, 2.5; p = 0.008) and HR = 1.5 (95% CI: 1.0, 2.2; p = 0.048). CONCLUSION: In the elderly, the extent of the dorsal fractures and the presence of ventral comminution/dislocation were associated to the decision to undergo surgery, failure of conservative treatment and length of stay. Survival was related to horizontal sacral fractures and ventrally comminuted fractures. These characteristics thus represent a simplified but highly informative approach for the evaluation of pelvic ring fractures in the elderly. This approach can support clinical decision making, promote patient-centred treatment algorithms and thus improve the outcome of individualized care.

ABSTRACT

Background and Objectives: Femoral neck fractures are common and constitute one of the largest healthcare burdens of the modern age. Fractures within the joint capsule (intracapsular) provide a specific surgical challenge due to the difficulty in predicting rates of bony union and whether the blood supply to the femoral head has been disrupted in a way that would lead to avascular necrosis. Most femoral neck fractures are treated surgically, aiming to maintain mobility, whilst reducing pain and complications associated with prolonged bedrest. Materials and Methods: We performed a narrative review of intracapsular hip fracture management, highlighting the latest advancements in fixation techniques, generating an evidence-based algorithm for their management. Results: Multiple different fracture configurations are encountered within the category of intracapsular hip fractures, with each pattern having different optimal surgical strategies. Additionally, these injuries typically occur in patients where further procedures due to operative complications are associated with a considerable increase in mortality, highlighting the need for choosing the correct index operation. Conclusions: Factors such as pathological causes for the fracture, pre-existing symptomatic osteoarthritis, patient's physiological age and fracture displacement all need to be considered when choosing optimal management.

ABSTRACT

SUMMARY: After intramedullary nailing of tibia shaft fractures, torsional malalignment greater than 10 degrees occur in up to 41% of operated legs. The reason is the difficult clinical assessment of rotation intraoperatively, the large variation in absolute torsion of the tibia, and the absence of established reliable methods to fluoroscopically evaluate tibial rotation and compare with the contralateral side. We present here a fast and low-tech intraoperative method on how to achieve identical tibial torsion of the operated and noninjured side. The method can be used for tibia shaft and metaphyseal fractures and only requires a normal C-arm fluoroscope with 2 monitors. First, a true lateral image of the knee on the noninjured side with the femoral condyles aligned is obtained. Second, with the leg and the C-arm rotation and tilt fixed, the fluoroscope is moved parallel to the patient axis and a lateral ankle image is obtained and saved. The fibula position relative to the tibia at the level of the Volkmann tubercle on the lateral view defines the torsion of the tibia. The sequence described above is repeated on the operated side after implantation of the nail before proximal locking. On the operated side, the fibula position relative to the tibia should be identical to the noninjured side before proximal locking takes place. Otherwise, a rotational malalignment is present and must be corrected. The comparison between operated and noninjured side is easy on a fluoroscope with 2 monitors. The complete examination takes a few minutes and has minor additional radiation exposure. We performed the intraoperative torsion control in 10 patients and performed a postoperative low-dose Computer Tomography-control of the torsion of both legs and found the rotational deformity to be less than 10 degrees in all patients.

ABSTRACT

Tibialis posterior tendon dislocation, a rare complication in ankle fracture-dislocations, can impede anatomical reduction of the ankle mortise. We report on a 59-year-old healthy male with an open fracture-dislocation of the right ankle. Despite multiple attempts under direct vision of the anterior syndesmosis, anatomical reduction of the ankle mortise was not possible. Soft tissue windows in a computed tomography (CT) scan revealed the dislocated tibialis posterior tendon to be the impeding structure. At the level of the fibula fracture the tendon passed through the interosseous membrane anterior to the distal tibia and was then incarcerated in the medial talocrural joint before returning to the flexor retinaculum and its insertion on the navicular bone. Understanding the trauma mechanism and the course of the dislocated tendon as well as correct interpretation of CT and magnetic resonance images of the ankle enable surgeons to early diagnose and correctly treat this condition.

ABSTRACT

BACKGROUND/AIM: Free flap reconstruction with damaged or diseased vessels is a challenging problem. We describe our case series using an arteriovenous loop or bypass surgery with free flaps for complex defect reconstructions at the lower extremity and the pelvic region. PATIENTS AND METHODS: In this single-center retrospective cohort study 11 consecutive patients (mean age=73 years, range=53-88 years) were operated on, between June 2016 and August 2018. Patients were reconstructed with free gracilis flaps (n=8), free latissimus dorsi flap (n=1) and chimeric scapular flap (n=1), respectively. RESULTS: The mean loop length was 30 cm (range=12-40 cm). The loop/bypass revision rate was 27% (3/11), and the overall flap loss rate was 20% (2/10). After a mean follow-up time of 17 months (range=12-24 months), the limb salvage rate was 75% (6/8). CONCLUSION: We successfully reconstructed complex defects with poor recipient vessels using arteriovenous loops or bypass surgery and free flaps.

ABSTRACT

The majority of periprosthetic femoral fractures are treated surgically.Surgical treatment may be revision only, revision in combination with open reduction and internal fixation (ORIF), or ORIF only.The treatment decision is dependent on whether the stem is loose or not, but loose stems are not always identified, resulting in unsatisfactory treatments.This article presents an algorithmic approach to identifying loose stems around proximal femoral periprosthetic fractures, taking patient history, stem design, and plain radiographs into consideration. This approach may help identifying loose stems and increase the probability of effective treatments. Cite this article: EFORT Open Rev 2020;5:449-456. DOI: 10.1302/2058-5241.5.190086.

ABSTRACT

INTRODUCTION: Subtalar dislocations are rare injuries and treatment recommendations missing. Gross contamination and devascularisation are aspects supporting talectomy as potential treatment choice. Reconstruction in these cases can be challenging. The Masquelet technique presents one viable option. PRESENTATION OF CASE: A carpenter sustained a high energy chrush injury with traumatic open lateral talar dislocation qualifying as Gustillo Anderson type IIIc injury, a mangeled extremity index of 7 and gross contamination. The severity of soft tissue damage and contamination prompted the decision for talectomy before plastic coverage with a gracilis flap. Additionally a Masquelet procedure with cement spacer was initiated. After consolidation of the soft tissues a hindfoot arthrodesis with approximate preservation of leg length could be performed. In the course of treatment, the patient suffered no infection and could resume full weight bearing after nine months. The patient resumed his previous occupation with adapted workload and is satisfied with the treatment result. DISCUSSION: In the present case the principle options were talus preservation or talectomy with reconstruction. Talus preservation in the presence of gross contamination can be associated with the risk of infection, in addition there is a risk to develop secondary arthritis. For this individual patient the a fast and definite solution was important at this point in life. Surgeons therefore opted for talectomy. To optimally reconstruct leg length and optimize for arthrodesis the Masquelet technique was employed. CONCLUSION: The Masquelet technique is a viable option also in the emergency situation to preserve extremity length and optimize tissue viability.

ABSTRACT

Long bone defects are often treated by bone segment transport with the Ilizarov method requiring months spent with fixator mounted until bony consolidation of the newly formed bone. Shortening of consolidation would allow earlier fixator removal and earlier return to work. In pre-clinical studies parathyroid hormone, increased bone mineral density and mechanical properties of regenerate bone formed during distraction osteogenesis. Clinical studies showed that Teriparatide accelerated fracture healing in patients with osteoporotic fracture of the pelvis, hip, wrist and shoulder. We hypothesized that rhPTH(1-34) (Teriparatide) administered to patients who had undergone distraction osteogenesis, would increase mineralization of the regenerate formed during the consolidation phase. Sixteen patients with tibial defects after infection, underwent bone segment transport and at the time of docking the transport segment, were randomized to 8 weeks treatment with daily subcutaneous 0.20-µg Teriparatide injection followed by 8 weeks with no treatment, or to 8 weeks with no treatment followed by 8 weeks with daily subcutaneous 0.20 µg Teriparatide injection. Bone mineral density (BMD) of the regenerate was measured at the time of docking, 8 weeks after docking and 16 weeks after docking with DEXA. Functional evaluation was performed after one year. The design was a cross-over study. Overall BMD increased 0.14 g/cm2 in 8 weeks without treatment and 0.33 g/cm2 under Teriparatide treatment. After adjustment for a potential phase difference, 8 weeks of Teriparatide treatment led to an additional 0.19 g/cm2 BMD increase (95%-CI:[0.11,0.28], p < 0.001). The ratio of the BMD increase between the two treatments was 0.33/0.14 = 2.43 (CI: [1.21,3.65]). Teriparatide treatment during the consolidation phase of distraction osteogenesis doubled the mineralization rate of the regenerate when compared to no treatment.

ABSTRACT

Fracture-related infection (FRI) is one of the most challenging complications in orthopaedic trauma surgery. It has severe consequences for patients and an important socio-economic impact. FRI has distinct properties and needs to be addressed interdisciplinary. Since criteria for the diagnosis of FRI are not standardized, an expert panel recently proposed a definition for FRI. In this review the current diagnostic modalities and an interdisciplinary diagnostic algorithm based on this recently published definition, are presented and future diagnostic techniques discussed. Since to date, there is no single universal diagnostic test available that gives the clinician the definitive diagnosis of FRI, it is mandatory to follow a standardized diagnostic algorithm to correctly diagnose FRI.

ABSTRACT

BACKGROUND: Low energy pelvic ring fractures in the elderly have traditionally been treated conservatively, a treatment with potential long-term complications and loss of self-independence. Percutaneous screw stabilisation of the posterior pelvic ring is a new treatment modality that enables immediate mobilisation. The aim of this study was to assess the functional outcome after sacroiliac stabilisation in the elderly. METHODS: All elderly patients with a surgically stabilised low energy pelvic fracture between 2010 and 2015 were included. In 2016 a radiographic follow up and functional test was performed at least one year postoperative. RESULTS: The 50 operated patients had a mean age of 79 years and a one-year mortality of 10% (5/50). Only six patients lost independency after the pelvic fracture and moved to nursing home. The mean Timed Up and Go test was 16s at follow-up. The operation of the posterior pelvic ring averaged 63min with a radiation equal to a diagnostic pelvic CT. One intra-foraminally placed screw was immediately removed and 9 patients were later re-operated on due to symptomatic loosening of one or more screws. No loosening of screws was seen in 11 patients where both S1 and S2 were stabilised and out of 23 trans-sacral screws (crossing both sacroiliac joints) only two loosened. DISCUSSION: CT guided stabilisation of the posterior pelvis is safe and most patients resumed good function and independent living. The risk of a revision operation was 20%, but trans-sacral screw stabilisation in both S1 and S2 could reduce the risk of implant loosening.

ABSTRACT

PURPOSE: Open tibial fractures needing soft tissue cover are challenging injuries. Infection risk is high, making treatment difficult and expensive. Delayed skin closure has been shown to increase the infection rate in several studies. We aimed at calculating the direct and indirect cost of treatment, and to determine the effect of delayed skin closure on this cost. METHODS: We reviewed all records of patients treated with a free flap in our institution for an open tibial fracture from 2002 to 2013. We calculated direct costs based on length of stay (LOS) and orthopaedic and plastic surgical procedures performed, including medications and intensive care. We analysed indirect cost in terms of absenteeism and unemployment benefits. The primary goal was to establish the extra cost incurred by an infection. RESULTS: We analysed 46 injuries in 45 patients. Infection increased the LOS from 41 to 74 days and increased the cost of treatment from € 49,817 in uninfected fractures to € 81,155 for infected fractures. Employed patients spent 430 days more on unemployment benefits, than a matched cohort in the background population. Achieving skin cover within seven days of injury decreased the infection rate from 60 to 27 %. CONCLUSIONS: Severe open tibial fractures covered with free flaps, cause over a year of absenteeism. Infection increases direct cost of treatment over 60 % and roughly doubles LOS. Early soft-tissue cover and correct antibiotics have been shown to improve outcomes-underscoring the need for rapid referral to centres with an ortho-plastic set-up to handle such injuries.

ABSTRACT

OBJECTIVE: Exsanguination due to coagulopathy and vascular injury is a common cause of death among trauma patients. Arterial injury can be treated either by angiography and embolization or by explorative laparotomy and surgical packing. The purpose of this study was to compare 30-day mortality and blood product consumption in trauma patients with active arterial haemorrhage in the abdominal and/or pelvic region treated with either angiography and embolization or explorative laparotomy and surgical packing. MATERIAL AND METHODS: From January 1(st) 2006 to December 31(st) 2011 2,173 patients with an ISS of >9 were admitted to the Trauma Centre of Copenhagen University Hospital, Rigshospitalet, Denmark. Of these, 66 patients met the inclusion criteria: age above 15 years and active arterial haemorrhage from the abdominal and/or pelvic region verified by a CT scan at admission. Gender, age, initial oxygen saturation, pulse rate and respiratory rate, mechanism of injury, ISS, Probability of Survival, treatment modality, 30-day mortality and number and type of blood products applied were retrieved from the TARN database, patient records and the Danish Civil Registration System. RESULTS: Thirty-one patients received angiography and embolization, and 35 patients underwent exploratory laparotomy and surgical packing. Gender, age, initial oxygen saturation, pulse rate and respiratory rate, ISS and Probability of Survival were comparable in the two groups. CONCLUSION: A significant increased risk of 30-day mortality (P = 0.04) was found in patients with active bleeding treated with explorative laparotomy and surgical packing compared to angiography and embolization when data was adjusted for age and ISS. No statistical significant difference (P > 0.05) was found in number of transfused blood products applied in the two groups of patients.

ABSTRACT

BACKGROUND AND PURPOSE: During acetabular fracture surgery, the acetabular roof is difficult to visualize with 2-dimensional fluoroscopic views. We assessed whether intraoperative 3-dimensional (3D) imaging can aid the surgeon to achieve better articular reduction and improve implant fixation. PATIENTS AND METHODS: We operated on 72 acetabular fractures using intraoperative 3D imaging and compared the operative results, duration of surgery, and complications with those for 42 consecutive acetabular fracture operations conducted using conventional fluoroscopic imaging. Postoperative reduction was evaluated on reconstructed coronal and sagittal images of the acetabulum. RESULTS: The fracture severity and patient characteristics were similar in the 2 groups. In the 3D group, 46 of 72 patients (0.6) had a perfect result after open reduction and internal fixation, and in the control group, 17 of 42 (0.4) had a perfect result. The mean difference in postoperative articular incongruity was 0.5 mm (95% CI: 0.4-0.7). In 29 of 72 operations, the intraoperative 3D scans led to intraoperative correction of the reduction and an improved result. The duration of surgery and infection rate were similar in the 2 groups. INTERPRETATION: Intraoperative 3D imaging, which is not time-consuming, allowed the surgeon to correct malreductions and screw placement in 29 of 72 operations, leading to better articular reduction and more precise screw placement than in operations where conventional fluoroscopic imaging was used to control the reduction.

ABSTRACT

BACKGROUND: Our aims were to determine the incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) that required inpatient or outpatient treatment, and to identify specific risk factors associated with DVT/PE in patients who had undergone surgery for a fracture distal to the knee. METHODS: Using individual linkage of nationwide registries, we included all Danish patients who had undergone surgery for a fracture distal to the knee between 1999 and 2011. Patients were followed for 180 days from discharge. Event rates of DVT/PE were calculated, and significant risk factors were identified with use of multivariable Cox regression analyses. Routine postdischarge antithrombotic chemoprophylaxis was not given to these patients. RESULTS: The study included 57,619 patients, 594 of whom had a venous thromboembolic event during the follow-up period. Thirty-nine (6.6%) of the 594 events were death due to PE. The overall event rate during the 180-day study period was 1.0%. The incidence rate was 7.28 events per 100 person-years before discharge, decreasing to a stable level below one event per 100 person-years in week 13 to 14 after discharge. Use of oral contraception by patients eighteen to fifty years of age (hazard ratio [HR] = 5.23, 95% confidence level [CI] = 3.35 to 8.18), previous DVT (HR = 6.27, 95% CI = 4.18 to 9.40), previous PE (HR = 5.45, 95% CI = 3.05 to 9.74), coagulopathy (HR = 2.47, 95% CI = 1.07 to 5.72), and peripheral artery disease (HR = 2.34, 95% CI = 1.20 to 4.56) were the factors associated with the highest risk of postoperative DVT/PE. Also, increasing age, increasing body mass index, cancer, and treatment with nonsteroidal anti-inflammatory drugs were associated with a significantly increased risk of DVT/PE. CONCLUSIONS: The incidence of DVT/PE was low following surgery for fractures distal to the knee; however, the risk was increased in the presence of a number of risk factors. This study suggests that specific groups of patients undergoing surgery for a fracture distal to the knee might benefit from postdischarge antithrombotic treatment.

ABSTRACT

PURPOSE: Treatment of open fractures is complex and controversial. The purpose of the present study is to add evidence to the management of open tibial fractures, where tissue loss necessitates cover with a free flap. We identified factors that increase the risk of complications. We questioned whether early flap coverage improved the clinical outcome and whether we could improve our antibiotic treatment of open fractures. METHODS: From 2002 to 2013 we treated 56 patients with an open tibial fracture covered with a free flap. We reviewed patient records and databases for type of trauma, smoking, time to tissue cover, infection, amputations, flap loss and union of fracture. We identified factors that increase the risk of complications. We analysed the organisms cultured from open fractures to propose the optimal antibiotic prophylaxis. Follow-up was a minimum of one year. Primary outcome was infection, bacterial sensitivity pattern, amputation, flap failure and union of the fracture. RESULTS: When soft tissue cover was delayed beyond seven days, infection rate increased from 27 to 60 % (p < 0.04). High-energy trauma patients had a higher risk of amputation, infection, flap failure and non-union. Smokers had a higher risk of non-union and flap failure. The bacteria found were often resistant to Cefuroxime, aminoglycosides or amoxicillin, but sensitive to vancomycin or meropenem. CONCLUSION: Flap cover within one week is essential to avoid infection. High-energy trauma and smoking are important predictors of complications. We suggest antibiotic prophylaxis with vancomycin and meropenem until the wound is covered in these complex injuries.

ABSTRACT

BACKGROUND: Operative treatment of displaced calcaneal fractures should restore joint congruence, but conventional fluoroscopy is unable to fully visualize the subtalar joint. We questioned whether intraoperative 3-dimensional (3D) imaging would aid in the reduction of calcaneal fractures, resulting in improved articular congruence and implant positioning. METHOD: Sixty-two displaced calcaneal fractures were operated on using standard fluoroscopic views. When the surgeon had achieved a satisfactory reduction, an intraoperative 3D scan was conducted, malreductions or implant imperfections were revised, the calcaneus was rescanned, and this sequence was repeated until the optimal operative result was achieved. RESULTS: Five fractures underwent 1 intraoperative scan, 39 fractures underwent 2 scans, 13 fractures underwent 3 scans, and 5 fractures underwent 4 scans. The average number of scans was 2.3. Intraoperative scanning led to re-reduction and improvement of reduction in 13 fractures, change of plate position in 1 patient, optimizing of the screw directions in 5 fractures, and shortening of screws that were intra-articular or protruding medially in 6 fractures. The postoperative articular displacement was 0 mm in 69% of the Sanders type 2 fractures and 57% of the Sanders type 3 fractures. Operation duration averaged 118 minutes, and there were no reoperations due to misplaced screws or plates. The average absorbed radiation dose per patient was 288 mGy·cm. CONCLUSION: Intraoperative 3D imaging improved the articular reduction of the posterior facet and secured optimal implant position in displaced calcaneal fractures. Radiation dose to the patient was less than that of a normal foot computed tomography scan. LEVEL OF EVIDENCE: Level IV, case series.
