The effectiveness of ambulatory continuous popliteal sciatic nerve blockade on patient-reported overall benefit of analgesia in patients undergoing foot or ankle surgery (CAREFREE trial); a randomized, open label, non-inferiority trial.

STUDY OBJECTIVE: Management of pain after foot and ankle surgery remains a concern for patients and healthcare professionals. This study determined the effectiveness of ambulatory continuous popliteal sciatic nerve blockade, compared to standard of care, on overall benefit of analgesia score (OBAS) in patients undergoing foot or ankle surgery. We hypothesized that usage of ambulatory continuous popliteal sciatic nerve blockade is non-inferior to standard of care. DESIGN: Single center, randomized, non-inferiority trial. SETTING: Tertiary hospital in the Netherlands. PATIENTS: Patients were enrolled if ≥18 years and scheduled for elective inpatient foot or ankle surgery. INTERVENTION: Patients were randomized to ambulatory continuous popliteal sciatic nerve blockade or standard of care. MEASUREMENTS: The primary outcome was the difference in OBAS, which includes pain, side effects of analgesics, and patient satisfaction, measured daily from the first to the third day after surgery. A non-inferiority margin of 2 was set as the upper limit for the 90% confidence interval of the difference in OBAS score. Mixed-effects modeling was employed to analyze differences in OBAS scores over time. Secondary outcome was the difference in opioid consumption. MAIN RESULTS: Patients were randomized to standard of care (n = 22), or ambulatory continuous popliteal sciatic nerve blockade (n = 22). Analyzing the first three postoperative days, the OBAS was significantly lower over time in the ambulatory continuous popliteal sciatic nerve blockade group compared to standard of care, demonstrating non-inferiority (-1.9 points, 90% CI -3.1 to -0.7). During the first five postoperative days, patients with ambulatory continuous popliteal sciatic nerve blockade consumed significantly fewer opioids over time compared to standard of care (-8.7 oral morphine milligram equivalents; 95% CI -16.1 to -1.4). CONCLUSIONS: Ambulatory continuous popliteal sciatic nerve blockade is non-inferior to standard of care with single shot popliteal sciatic nerve blockade on patient-reported overall benefit of analgesia.

Measuring External Rotation of the Fibula and Fibular Length in Bilateral Computed Tomography Scans: How Reliable Is This Method?

OBJECTIVES: During ankle fracture surgery, goals include accurate reduction and fixation of the fibula regarding rotation and fibular length. Bilateral postoperative computed tomography (CT) can be performed to assess fibular rotation using the talar dome angle, and fibular length. The aim of this study was to compare side-to-side differences of the fibular rotation and fibular length using bilateral CT scans of uninjured ankles. DESIGN: Retrospective. SETTING: Single center, Level I Academic Trauma Center. PATIENT SELECTION CRITERIA: Patients with bilateral CT scans of uninjured ankles. OUTCOME MEASURES AND COMPARISONS: External rotation using the Nault talar dome method and fibular length using the coronal method of Prior et al. The average, difference, and ratio (injured side/healthy side) and interobserver variability were calculated. RESULTS: There were 83 patients included (166 ankles, mean age 47 years, 77.1% male). A random set of 66 ankles (33 CT scans) were used to measure interobserver variability. The mean degrees of external rotation ranged from 6.6 to 7.7, mean difference ranged from 1.4 to 3.4 degrees, mean ratio ranged from 1.1 to 1.5, and interobserver variability ranged from 0.27 to 0.65. For fibular length, the mean ranged from 24.6 to 25.8 mm, mean difference in fibular length ranged from 0.5 to 2.1 mm, mean ratio ranged from 1.0 to 1.1 mm, and interobserver variability ranged from 0.45 to 0.73. CONCLUSIONS: Using bilateral ankle CT scans, mean differences in fibular rotation using the Nault talar dome method were 1.4-3.4 degrees. The distal fibular length had a mean difference between both sides of 0.5-2.1 mm. Although the intraclass correlation's were low, the interleg differences between patients were small, making them useful for clinical practice. LEVEL OF EVIDENCE: Diagnostic Level III.

IDENTIFICATION OF POTENTIALLY MODIFIABLE FACTORS TO IMPROVE RECOGNITION AND OUTCOME OF NECROTIZING SOFT-TISSUE INFECTIONS.

ABSTRACT: Background : Necrotizing soft-tissue infections (NSTIs) present a surgical emergency of increasing incidence, which is often misdiagnosed and associated with substantial mortality and morbidity. A retrospective multicenter (11 hospitals) cohort study was initiated to identify the early predictors of misdiagnosis, mortality, and morbidity (skin defect size and amputation). Methods : Patients of all ages who presented with symptoms and were admitted for acute treatment of NSTIs between January 2013 and December 2017 were included. Generalized estimating equation analysis was used to identify early predictors (available before or during the first debridement surgery), with a significance level of P < 0.05. Results : The median age of the cohort (N = 216) was 59.5 (interquartile range = 23.6) years, of which 138 patients (63.9%) were male. Necrotizing soft-tissue infections most frequently originated in the legs (31.0%) and anogenital area (30.5%). More than half of the patients (n = 114, 54.3%) were initially misdiagnosed. Thirty-day mortality was 22.9%. Amputation of an extremity was performed in 26 patients (12.5%). Misdiagnosis was more likely in patients with a higher Charlson Comorbidity Index (ß = 0.20, P = 0.001), and less likely when symptoms started in the anogenital area (ß = -1.20, P = 0.003). Besides the established risk factors for mortality (septic shock and age), misdiagnosis was identified as an independent predictor of 30-day mortality (ß = 1.03, P = 0.01). The strongest predictors of the final skin defect size were septic shock (ß = 2.88, P < 0.001) and a skin-sparing approach to debridement (ß = -1.79, P = 0.002). Conclusion : Recognition of the disease is essential for the survival of patients affected by NSTI, as is adequate treatment of septic shock. The application of a skin-sparing approach to surgical debridement may decrease morbidity.

Adjunctive hyperbaric oxygen therapy in the management of severe lower limb soft tissue injuries: a systematic review.

PURPOSE: Traumatic crush injuries of the lower limb often accompany severe complications. The incorporation of hyperbaric oxygen therapy to standard trauma care may have the potential to diminish injury-related complications and improve outcome in such cases. This systematic review aims to evaluate the effectiveness of hyperbaric oxygen therapy in the management of severe lower limb soft tissue injuries. METHODS: The electronic databases Medline, Embase and Cochrane Library were searched to identify studies involving patients with crush-associated sever lower limb soft tissue injuries who received hyperbaric oxygen therapy in conjunction with standard trauma care. Relevant data on type of injury, hyperbaric oxygen therapy protocol and outcome related to wound healing were extracted. RESULTS: In total seven studies met the inclusion criteria, involving 229 patients. The studies included two randomized clinical trials, one retrospective cohort study, three case series and one case report. The randomized placebo-controlled clinical trial showed a significant increase in wound healing and decrease in the need for additional surgical interventions in the patient group receiving hyperbaric oxygen therapy when compared to those undergoing sham therapy. The randomized non-placebo-controlled clinical trial revealed that early hyperbaric oxygen therapy reduces tissue necrosis and the likelihood of long-term complications. The retrospective cohort study indicated that hyperbaric oxygen therapy effectively reduces infection rates and the need for additional surgical interventions. The case series and case report presented beneficial results with regard to wound healing when hyperbaric oxygen therapy was added to the treatment regimen. CONCLUSION: Hyperbaric oxygen therapy is generally considered a safe therapeutic intervention and seems to have a beneficial effect on wound healing in severe lower limb soft tissue injuries when implemented as an addition to standard trauma care.

Non-compressible truncal and junctional hemorrhage: A retrospective analysis quantifying potential indications for advanced bleeding control in Dutch trauma centers.

BACKGROUND: Truncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques. METHODS: Adult trauma patients with an Abbreviated Injury Scale ≥3 in the torso, neck, axilla, or groin region, who were presented between January 1st, 2014 and December 31st, 2018 to two Dutch level-1 trauma centers, were identified from the Dutch Trauma Registry. Potential indications for advanced bleeding control in patients with NCTJH were assessed by an expert panel of three trauma surgeons based on injury characteristics, vital signs, response to resuscitation, and received treatment. RESULTS: In total, 1719 patients were identified of whom 249 (14.5 %) suffered from NCTJH. In 153 patients (60.6 %), hemorrhagic shock could have been mitigated or prevented with advanced bleeding control techniques. This group was younger and more heavily injured: median age of 40 versus 48 years and median ISS 33 versus 22 as compared to the entire cohort. The mortality rate in these patients was 31.8 %. On average, each of the included level-1 trauma centers treated an NCTJH patient every 24 days in whom a form of advanced bleeding control could have been beneficial. CONCLUSIONS: More than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage.

Pelvic Ring Fractures in Older Adult Patients-Assessing Physician Practice Variation among (Orthopedic) Trauma Surgeons.

PURPOSE: Pelvic fractures in older adults are a major public health problem and socioeconomic burden. The standard of care has changed over the past years, and there is limited consensus on which patients benefit from surgical fixation. There is currently no nationwide treatment protocol to guide the decision-making process. Therefore, the aim of this survey was to provide more insight into if, when, and why patients with a fragility fracture of the pelvis (FFPs) would be considered for additional imaging and surgical fixation by treating physicians. METHODS: An online clinical vignette-based survey of hypothetical scenarios was sent out to all orthopedic and trauma surgeons in the Netherlands. The questionnaire comprised multiple-choice questions and radiographic images. Differences between subgroups were calculated using the X2 test or the Fisher exact test. RESULTS: 169 surgeons responded to the survey, with varying levels of experience and working in different types of hospitals. In a patient with a simple pubic ramus fracture and ASA 2 or ASA 4, 32% and 18% of the respondents would always advise a CT scan for further analysis. In the same patients, 11% and 31% of the respondents would not advise a CT scan, respectively. When presented with three cases of increasing severity of co-morbidity (ASA) and/or increasing age and/or different clinical presentation of an FFP type 3c on a CT scan, an increasing number of respondents would not consider surgical fixation. There was significant variation in practice patterns between the respondents who do not work in a hospital performing pelvic and acetabular (P&A) fracture surgery and those who do work in a P&A referral hospital. Most respondents (77%) refer patients 1-5 times a year to an expert center for surgical fixation. CONCLUSION: There is currently a wide variety of clinical practices regarding the imaging and management of FFPs, which seems to be influenced by the type of hospital the patients are presented to. A regional or national evidence-based treatment protocol should be implemented to ensure a more uniform approach.

Implant Choice and Outcomes of the Sinus Tarsi Approach for Displaced Intra-articular Calcaneal Fractures.

BACKGROUND: Operative fixation of displaced intra-articular calcaneal fractures is considered the gold standard, for which multiple fixation methods are available. This study compares the (functional) outcome of screw fixation (SF), plate fixation (PF), and anatomical plate fixation (APF) via the sinus tarsi approach (STA). METHODS: A total of 239 patients (265 fractured calcanei) who received surgical treatment of a displaced intra-articular calcaneal fracture via STA between 2011 and 2022 were included. RESULTS: Böhler angle (BA) measured immediately postoperatively (BA post-OR) and the decrease in BA at 1 year (∆BA) differed significantly in favor of PF/APF compared with SF (BA post-OR: SF vs PF P = .010 and SF vs APF P = .001; ∆BA: SF vs PF P = .032 and SF vs APF P = .042). Implant removal surgery was performed significantly less in the APF group as compared to the SF/PF groups (APF vs SF/PF; 9.9% vs 22.9%/23.7%, P = .015). Surgical site infections and secondary arthrodesis of the subtalar joint occurred equally in the 3 groups. Furthermore, the mean American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, Foot Function Index score, and EuroQOL-5D-index / visual analog scale score, did not differ notably between SF, PF, and APF. CONCLUSION: The results show that both PF and APF are favored over SF because of an improved correction of BA measured directly postoperatively, a lower secondary loss of BA and, for APF, a lower implant removal rate. There was no difference in the rate of surgical site infections, need for secondary arthrodesis, nor functional outcome scores between different implants using the STA. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

In-House Attending Trauma Surgeon Does Not Reduce Mortality in Patients Presented to a Level 1 Trauma Center.

BACKGROUND: Trauma is the leading cause of death in the Western world. Trauma systems have been paramount in opposing this problem. Commonly, Level 1 Trauma Centers are staffed by in-house (IH) attending trauma surgeons available 24/7, whereas other institutions function on an on-call (OC) basis with defined response times. There is on-going debate about the value of an IH attending trauma surgeon compared to OC trauma surgeons regarding clinical outcome. METHODS: This study was performed at a tertiary care facility complying with all requirements to be a designated Level 1 Trauma Center as defined by the American College of Surgeons Committee on Trauma (ACSCOT). Inclusion occurred from January 1, 2012 through December 31, 2013. Patients were assigned an identifier for IH trauma surgeon attendance versus OC attendance. The primary outcome variable studied was overall mortality in relation to IH or OC attending trauma surgeons. Additionally, time to operating theater, hospital length-of-stay (HLOS), and intensive care unit (ICU) admittance were investigated. RESULTS: A total of 1,287 unique trauma cases in 1,285 patients were presented to the trauma team. Of all cases, 712 (55.3%) occurred between 1700h and 0800h. These 712 cases were treated by an IH attending in 66.3% (n = 472) and an OC attending in 33.7% (n = 240). In the group of patients treated by an IH attending trauma surgeon, the overall mortality rate was 5.5% (n = 26); in the group treated by an OC attending, the overall mortality rate was 4.6% (n = 11; P = .599). Cause of death was traumatic brain injury (TBI) in 57.6%. No significant difference was found in the time between initial presentation at the trauma room and arrival in the operating theater. CONCLUSION: In terms of trauma-related mortality during non-office hours, no benefit was demonstrated through IH trauma surgeons compared to OC trauma surgeons.

Functional outcome and quality of life in surgically treated talar neck and body fractures; how is it affected by complications.

BACKGROUND: Since talus fractures are rare, study populations are frequently small. The aim of this study is to describe how surgical treatment of talar neck and body fractures and postoperative complications affect functional outcome and quality of life measured by validated questionnaires. METHODS: All patients following surgically treated talar neck and/or body fracture between January 2000 and December 2019 at a level 1 trauma center were included in this retrospective cohort study. Primary outcomes were functional outcomes measured by Lower Extremity Functional Score (LEFS), the Foot Function Index (FFI), and the Quality of Life (QOL) measured by the EuroQol 5-dimension questionnaire (EQ-5D). Linear regression was used to assess the relationship between continuous variables and the outcome, and multivariable linear regression was used to identify the predictors of the functional outcome. RESULTS: Ninety patients were included, of which 73 responded to our questionnaires. The median follow-up time was 50.5 (interquartile range (IQR), 18.3-97.3) months. Our study showed the following results: a mean LEFS of 58.4 (range, 17-80), a median FFI of 15.7 (IQR, 3.5-35.2), a median EQ-5D index score of 0.83 (IQR, 0.81-1.00), a median patient satisfaction of 9.0 (IQR, 8.0-10.0), a patient reported health status of 76.8 (range, 20-100), and a mean AOFAS score of 75.7 (range, 28-100). Implant removal and secondary arthrodesis were associated with a reduced AOFAS outcome score (p=0.001, p<0.001), and implant removal was also a predictive factor for a less favorable LEFS outcome score (p=0.001). CONCLUSION: Patients who underwent implant removal and/or secondary arthrodesis had poorer functional outcome compared to patients who did not undergo additional procedures. Careful consideration of re-intervention must be made in combination with patient expectation management. Future studies should focus on how to lower the rate of complications and the effect of secondary intervention with the use of validated questionnaires.

Long-Term Follow-up of Functional and Radiographic Outcome After Revision Surgery for Fibula Malunion.

Background. Ankle fractures are some of the most common injuries seen in the emergency department. Malunited ankle fractures are uncommon. Patients with malunion frequently present with multiple complaints. Radiographs often show abnormalities in anatomical alignment. Aim. To evaluate the anatomical alignment on radiographic imaging in patients with malunited ankle fractures. Secondary aims were to evaluate patient satisfaction after reconstruction and to investigate the relationships between radiological alignment and functional outcome. Methods. All consecutive patients (n = 25) treated for a fibula malunion between January 1, 2002, and September 1, 2017, were included. The primary outcome was anatomical alignment of the ankle mortise. The talocrural angle (TCA), talar tilt (TT), and medial clear space (MCS) were used to investigate to what extent revision surgery had improved alignment. The patient-related outcome measure consisted of the Olerud and Molander Ankle Score (OMAS). To assess quality of life (QoL) the EQ-5D-5L was used. Results. The median TCA was 78.4° before revision and 79.25° after revision; P = .297. The median TT was 2.95° before revision and 0.70° after; P < .001. The MCS before revision was 5.2 mm and 3.17 mm after; P < .000). The OMAS had a median of 67.5 points. Analysis of the QoL questionnaires yielded a score of 0.84 points. Conclusion. Anatomical alignment improves significantly after revision surgery of malunited ankles. Measurements of the TCA appeared less useful in determining the anatomical alignment. In our series, 60% of patients reported good to excellent results. The QoL scores of our patient were comparable to those in the healthy population in the Netherlands.Levels of Evidence: Level IV: Case series.

Determining the Correlation Between Lateral Radiograph Morphology and the Outcome Following Surgically Treated Intra-Articular Calcaneal Fractures.

Purpose. It is currently still common practice to obtain conventional radiographs in the follow-up of surgically treated displaced intra-articular calcaneal fractures at regular intervals. There is, however, insufficient evidence that these radiographs can be used to predict functional outcome. The aim of the current study was to evaluate the correlation between the most commonly used angles on lateral radiographs and disease-specific patient-reported outcome measures (PROMs). Methods. Two available databases, containing a total of 233 patients, were used in this study. Eleven angles on the lateral images of the preoperative and at 1-year follow-up radiographs were measured. The 6 most commonly used angles were also measured immediately postoperatively. These 6 most commonly used angles were correlated with PROMs (American Orthopaedic Foot and Ankle Society hindfoot score, Foot Function Index) by a Spearman's rho analysis. After a Bonferroni correction was applied, a P value of <.0042 was considered to be statistically significant. Results. After exclusion of bilateral fractures, primary arthrodesis, open fractures, wound infections, other wound complications, nonavailable radiographs, and nonresponders, 86 patients remained. No significant correlations were found between the measured angles on the preoperative and at 1-year follow-up radiographs and the PROMs. Conclusion. No apparent correlation between lateral radiograph morphology and outcome was detected. Therefore, long-term follow-up radiographs after confirmed healing may be restricted to patients with persistent complaints on indication.Levels of Evidence: Prognostic, Level IV: Retrospective.

Bipolar clavicular fractures and treatment options.

INTRODUCTION: Fractures of the clavicle are common injuries, accounting 2.6-4% of all fractures in adults. Of these fractures, 21-28% are lateral clavicle fractures and 2-3% are medial clavicle fractures. Bipolar clavicle fractures are defined as a lateral and medial fracture and are uncommon. There is no consensus on the treatment of these fractures. The aim of this study is to provide a treatment on bipolar clavicle fractures based on the current literature. METHODS: The electronic databases PubMed, the Cochrane library and EMBASE were searched up on September 25th, 2017. Two reviewers (KR and TG) independently screened titles and abstracts for their relevance. Studies designed to evaluate the outcomes of conservative and/or operative treatment of segmental bipolar clavicle fractures in adults (> 16 years) were included. Editorials and commentaries were excluded, as well as synthetic, cadaveric and animal studies. Primary outcomes considered were pain reduction and shoulder function. Secondary outcomes considered are complications. RESULTS: Ten studies reporting results from ten patients were included for the review. In most patients, if treated operatively, surgical treatment with the use of double plating was performed. Only in elderly patients conservative treatment was adopted. All included patients were pain free and had a full range of motion after 3-6 months. Only two case reports provided a DASH score, while in eight studies no functional outcome score was measured. CONCLUSION: A missed bipolar fracture can complicate the clinical progress. Surgical management of these fractures may be necessary; however, the treatment of choice depends on the age of the patient, daily activities and comorbidity.

Intraoperative Effect of 2D vs 3D Fluoroscopy on Quality of Reduction and Patient-Related Outcome in Calcaneal Fracture Surgery.

BACKGROUND: Three-dimensional (3D) fluoroscopy is thought to be advantageous in the open reduction and internal fixation (ORIF) of calcaneal fractures. The goal of this multicenter randomized controlled trial was to investigate the clinical effect of additional intraoperative 3D fluoroscopy on postoperative quality of reduction and fixation and patient-reported outcome as compared to conventional 2-dimensional (2D) fluoroscopy in patients with intra-articular fractures of the calcaneus. METHODS: Patients were randomized to 3D or conventional 2D fluoroscopy during operative treatment of calcaneal fractures. Primary outcome was the difference in quality of fracture reduction and implant position on postoperative computed tomography (CT). Secondary endpoints included intraoperative corrections (prior to wound closure), complications, and revision surgery (after wound closure). Function and patient-reported outcome were evaluated after surgery and included range of motion, Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) score, Short-Form 36 (SF-36) questionnaires, and Kellgren-Lawrence posttraumatic osteoarthritis classification. A total of 102 calcaneal fractures were included in the study in 100 patients. Fifty fractures were randomized to the 3D group and 52 to the 2D group. RESULTS: There was a statistically significant difference in duration of surgery between the groups (2D 125 min vs 3D 147 min; P < .001). After 3D fluoroscopy, a total of 57 intraoperative corrections were performed in 28 patients (56%). The postoperative CT scan revealed an indication for additional revision of reduction or implant position in 69% of the 3D group vs 60% in the 2D fluoroscopy group. At 2 years, there was no difference in number of revision surgery, complications, FAOS, AOFAS score, SF-36 score, or posttraumatic osteoarthritis. CONCLUSION: The use of intraoperative 3D fluoroscopy in the treatment of intra-articular calcaneal fractures prolongs the operative procedures without improving the quality of reduction and fixation. There was no benefit of intraoperative 3D fluoroscopy with regard to postoperative complications, quality of life, functional outcome, or posttraumatic osteoarthritis.Level of Evidence: Level I, prospective randomized controlled study.

Health-Related Quality of Life Is Decreased After Necrotizing Soft-Tissue Infections.

BACKGROUND: A necrotizing soft-tissue infection (NSTI) is a rare but severe infection with a high mortality rate of 12%-20%. Diagnosing is challenging and often delayed. Treatment consists of surgical debridement of all necrotic tissue and administration of antibiotics. Despite adequate treatment, survivors are often left with extensive wounds, resulting in mutilating scars and functional deficits. Both the disease and the subsequent scars can negatively influence the health-related quality of life (HRQoL). The present study was performed to contribute to the knowledge about HRQoL in patients after NSTI. METHODS: We retrospectively identified patients treated for NSTI in a tertiary center in the Netherlands. Patient and treatment characteristics were collected and patients were asked to fill in a Short Form 36 questionnaire. RESULTS: Forty-six patients with a diagnosis of NSTI were identified. Twenty-eight (61%) were male and mean age was 57 y. Thirty-nine patients (80%) survived. Thirty-one (84%) of the survivors returned the questionnaire after a median follow-up of 4.1 y (interquartile range [IQR], 2.4-5.9 y). Statistically significantly decreased scores when compared to the Dutch reference values were observed for the Short Form 36 domains, physical functioning, role-physical functioning, general health, and the combined Physical Component Score. No differences were observed for the other five domains or for the Mental Component Score. CONCLUSIONS: This study confirms that NSTI negatively affects HRQoL as reported by the patient, especially on the physical domains. To learn more about HRQoL in patients after NSTI, studies in larger groups with a more disease-specific questionnaire should be performed. LEVEL OF EVIDENCE: Level 3, prognostic and epidemiological.

Lateral Process Fracture of the Talus: A Case Series and Review of the Literature.

Fracture of the lateral process of the talus (LPFT) is a frequently overlooked injury that can lead to severe complaints if not treated adequately. The aim of this study was to evaluate treatment and long-term outcomes of LPFT through a review of the literature. Furthermore, we propose a modified classification based on severity and intra- or extra-articular location of LPFT. Patients diagnosed with LPFT and treated at a Level 1 trauma center between 2001 and 2018 were included. Fracture and treatment characteristics were recorded in combination with functional outcome and quality of life after a mean follow-up of 5.5 (range 0.8 to 17.2) years. A comprehensive literature search was performed to identify all case series regarding patients with LPFT; 36 patients were included. According to our modified classification, 1 patient had type 1A (2.8%), 6 patients had type 1B (16.7%), 10 patients had type 2 (27.8%), 11 patients had type 3 (30.6%), 6 patients had type 4A (16.7%), and 2 patients had type 4B (5.6%). Twenty-eight patients underwent operative fixation (78%). The median American Orthopaedic Foot and Ankle Society Hindfoot Score was 75 (range 12 to 100). The median Foot Function Index was 2 (range 0 to 9). The median score for the EuroQol-5D was 0.8 (range -0.5 to 1), and the median score for health status component was 75 (range 30 to 98). There is some room for conservative treatment of LPFT; however, we strongly believe that this should be considered only for nondisplaced, small-fragment, and extra-articular fractures. Surgical treatment leads to an overall good (long-term) outcome.

Functional Outcome and Quality of Life After Nonoperative Treatment of Posterior Process Fractures of the Talus.

BACKGROUND: Fractures of the posterior process of the talus are frequently overlooked, possibly leading to nonunion, arthritis, and chronic pain. Given the rare occurrence, previous case series have been small and without functional outcome scores. Therefore, we aimed to provide evidence on outcomes after nonoperative and operative management of posterior process fractures of the talus. METHODS: All patients treated at a level 1 trauma center between 2012 and 2018 were retrospectively evaluated. Patient, fracture, and treatment characteristics were collected, and functional outcome as well as quality of life were assessed. Twenty-nine patients with posterior process fractures of the talus were identified in our database. RESULTS: The most frequently seen mechanism of trauma was fall from height in 13 patients (44.8%). Twenty-two patients underwent primary arthrodesis or operative reduction and fixation of the fracture (75.9%). Eighty-two percent of the patients returned the questionnaires with a mean follow-up of 6 years. The 2 patients with primary arthrodesis were excluded from outcome analysis. The mean Foot Function Index score was 1.8 (range 0.0-10). The mean American Orthopaedic Foot & Ankle Society (AOFAS) score was 78.7 points (range 0-100). The mean quality of life EuroQol-5D (EQ-5D) index score was 0.78 (range -0.26 to 1). The mean visual analog scale (VAS) on overall patient satisfaction was 8.2 (range 1-10). CONCLUSION: Operative management of extended posterior talar fractures was found to provide good functional outcome, quality of life, and patient satisfaction. Although the patients treated nonoperatively were found to have less severe injuries, they demonstrated worse overall outcome, which is supportive of surgical management. Nonoperative treatment is therefore only justified in selected patients. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Identification of Postoperative Step-Offs and Gaps With Brodén's View Following Open Reduction and Internal Fixation of Calcaneal Fractures.

BACKGROUND: To date, there is no consensus regarding which postoperative imaging technique should be used after open reduction and internal fixation of an intra-articular calcaneal fracture. The aim of this study was to clarify whether Brodén's view is sufficient as postoperative radiologic examination to assess step-offs and gaps of the posterior facet. METHODS: Six observers estimated the size of step-offs and gaps on Brodén's view in 42 surgically treated intra-articular calcaneal fractures. These findings were compared to postoperative CT scans (gold standard). Inter- and intraobserver reliability were calculated and compared using intraclass correlation coefficients (ICCs). RESULTS: An accuracy of approximately 75% for both step-offs and gaps was found in foot and ankle experts. Less experienced observers correctly identified step-offs and gaps in approximately 62% of cases on fluoroscopy and in 48% on radiographs. Interobserver reliability for intraoperative fluoroscopy as well as postoperative radiographs was fair for step-offs, whereas interobserver reliability for gaps was excellent. Intraobserver reliability showed a low level of agreement for intraoperative fluoroscopy, in contrast to postoperative radiographs with excellent agreement for step-offs and good agreement for gaps. CONCLUSION: Our results show that especially for more experienced foot and ankle surgeons, in the majority of fractures, Brodén's view accurately showed step-offs and gaps following open reduction and internal fixation. Interobserver reliability showed a fair level of agreement for step-offs and excellent agreement for gaps. Intraobserver reliability was only enough for radiographs, not for fluoroscopy.

Routine pelvic X-rays in asymptomatic hemodynamically stable blunt trauma patients: A meta-analysis.

INTRODUCTION: There is no consensus on how pelvic X-rays should be ordered selectively in blunt trauma patients which may save time, reduce radiation exposure and costs. The aim of this systematic review and meta-analysis was to assess the need for routine pelvic X-rays in awake, respiratory and hemodynamically (HD) stable blunt trauma patients without signs of pelvic fracture. Criteria to identify patients who could safely forgo pelvic X-ray were evaluated. METHODS: A literature search was performed for prospective comparative cohort studies. Inclusion criteria were: blunt force trauma, hemodynamically and respiratory stable and awake patients, physical examination (PE) for pelvic fractures was adequately described, and the reliability of negative PE findings could be evaluated. Primary outcome was the negative predictive value (NPV) of PE for all and for clinically relevant pelvic fractures. Additionally sensitivity, specificity and positive predictive value (PPV) were calculated. RESULTS: Ten studies were included; yielding a total of 11,423 patients. The NPV of PE for all pelvic fractures ranged from 0.96 to 1.00 with a median of 0.996. Combining studies, total NPV was 0.991. For clinically relevant fractures, the NPV of PE ranged from 0.996 to 1.00 with a median of 1.00. In patients with negative findings during PE, 0.9% had fractures, and 0.1% had clinically relevant fractures, none requiring surgical management. CONCLUSIONS: In awake, hemodynamically and respiratory stable blunt trauma patients, PE could identify those patients who could safely forgo pelvic X-ray. Selective ordering of pelvic X-ray may lead to a decrease in patient work-up time, lower radiation exposure, and reduce costs. A decision making flow chart is proposed..
