Pelvic Ring Fracture Management and Subsequent Pregnancy: A Summary of Current Literature.

INTRODUCTION: The incidence of pelvic ring injuries is 34.3% per 100,000 capita. No studies have determined the ability of a female patient to have a vaginal delivery after undergoing pelvic fracture fixation. However, many obstetricians are generally unwilling to have their patients attempt a vaginal delivery in the setting of symphyseal or sacroiliac fixation. METHODS: An exhaustive search of the National Library of Medicine database was performed, and it is hypothesized that cesarean section rates would be higher for women who have a child after one of these pelvic ring injuries. RESULTS: There is a 15% increase in cesarean rates using data from the National Center for Health Statistics. In addition, there is an observable increase in new cesarean rates. DISCUSSION: Currently, there is no clear evidence to support an elective cesarean section as the sole indication after a prior pelvic fracture. To date, no studies have determined the ability of a female patient to have a vaginal delivery after undergoing pelvic fracture fixation. CONCLUSION: Thus, until the increased cesarean section rate has been explained, it could be problematic to counsel the patient to avoid a vaginal delivery after sustaining a pelvic ring fracture. Hence, conducting additional studies on this topic would deem to be necessary.

Financial Analysis of Preoperative Nasal Decolonization With Povidone-Iodine in Closed Pilon Fracture Definitive Fixation.

The purpose of this study is to determine the financial practicality for the use of nasal povidone-iodine (NP-I) in the preoperative holding area in attempt to decrease the rate of infection that is associated with operative fixation of closed pilon fractures. Institutional costs for treating postoperative infection following a closed pilon fracture, along with costs associated with preoperative NP-I use, were obtained. A break-even equation was used to analyze these costs to determine if the use of NP-I would decrease the current infection rate (17%) enough to be financially beneficial for routine use preoperatively. The total cost of treating a postoperative infection was found to be $18,912, with the cost of NP-I being $30 per patient dose. Considering a 17% infection rate and utilizing the break-even equation, NP-I was found to be economically viable if it decreased the current infection rate by 0.0016% (Number Needed to Treat = 63,051.7). This break-even model suggests that the use of NP-I in the preoperative holding area is financially beneficial for decreasing the rate of infection associated with the treatment of closed pilon fractures.

Simplified soft tissue coverage of the distal lower extremity: The reverse sural flap.

Soft tissue defects involving the distal lower extremity present challenging problems for orthopaedic surgeons to manage. Historically, wounds not amenable to primary closure have necessitated assistance from multidisciplinary teams using plastic surgeons to obtain adequate soft tissue coverage through rotational flap or free tissue transfer procedures. Techniques related to soft tissue rearrangement and local rotational flap coverage have advanced over the years with a growing knowledge of local anatomy and vasculature. The reverse sural flap may be performed to cover soft tissue defects within 10 cm of the foot or ankle region, negating the need for microvascular intervention. The simplistic nature of the reverse sural flap is appealing to orthopaedic surgeons as a means to provide timely patient care without additional support because it does not require microvasculature work or the need for intraoperative microscopes and has been popularized among orthopaedic trauma surgeons as a necessary tool to possess. Here, we discuss the reverse sural flap to include history, relevant anatomy, clinical indications, and a description of the technique for application.

Injuries Sustained With Falls From Height in Crossing the United States-Mexico Border at a Level I Trauma Center: A Prospective Cohort Study.

INTRODUCTION: The US Department of Homeland Security has reported increases in encounters and apprehensions at the US Southwest border for the past several years. The purposes of this study were to assess the demographics, patterns of injuries, and surgical interventions, associated with falls from height along the US-Mexico border. METHODS: A prospective cohort study was conducted at a Level I trauma center from January 2016 through December 2021 of all patients who fell from height crossing the US-Mexico border and presented with injuries requiring admission. RESULTS: A total of 448 patients were admitted with a median age of 30 years (interquartile range [IQR] 16, range 6 to 65). Monthly frequency of admissions increased markedly with a median of 18.5 (IQR 5.3) in 2021. Patients presented with limited health data, and comorbidities were identified in 111 patients (24.7%). Median height fallen was 5.5 m (18 ft). Patients sustaining a fall from ≥ 5.5 m were markedly more likely to have an Injury Severity Score (ISS) of > 15. Median length of stay was 9 days (IQR 11). There were a total of 1,066 injuries with 723 extremity and pelvic; 236 spine; and 107 head or neck, face, thorax, or abdominal injuries. Median ISS was 9.0 (IQR 7, range 1 to 75, 33% > 15). Tibial plafond fracture and spine injury were markedly associated with longer lengths of stay and ISS > 15. All injuries resulted in 635 separate surgical events and 930 procedures. Clinical follow-up occurred in 55 patients (12.2%), with median duration of 28 days (range 6 days to 8 months). DISCUSSION: Injuries associated with border crossings and falls from height were serious and increased in frequency. As the US policy on border security evolves, surgeons in these regions should be prepared to handle the associated injuries and sequelae. Prevention of these serious and debilitating injuries should be undertaken to decrease the burden of disease.

Assessment of quality, absorbability, and educational value of YouTube videos regarding ankle fractures.

Aims & objectives: YouTube is a non-peer-reviewed platform with a large library of healthcare-related videos which attempt to provide educational content. The goal of this study is to analyze the quality, absorbability, and educational content of videos available to patients on YouTube regarding ankle fractures. Materials & methods: On May 31, 2022, over 550 videos populated the initial search of "ankle fracture" within YouTube's platform. The first 100 videos were reviewed, and 62 videos were included in the final analysis. Video characteristics were recorded and evaluated. Videos were assessed using three objective scoring systems: (1) the Journal of American Medical Association (JAMA) benchmark criteria, (2) the Patient Education Materials Assessment Tool for audio and visual materials (PEMAT), and (3) the novel Ankle Fracture Content Score (AFCS). Results: Each scoring system had high internal consistency and interrater reliability. The mean JAMA, PEMAT understandability, PEMAT actionability, and AFCS were 2.92, 61.85%, 16.38%, and 4.67, respectively. No association was seen between video popularity metrics and quality of information. The understandability of the patient-targeted videos was greater than those targeted at healthcare professionals (P = 0.049). Conclusion: The information regarding ankle fractures available on YouTube for patient education is poor with no correlation between quality and popularity. This study illustrates the need for future collaboration between YouTube and trusted medical societies to provide patients with the highest quality information.

Tibial Bone Transport With a Single Implant All-Internal Bone Transport Nail.

SUMMARY: A single implant all-internal magnet-driven bone transport nail (BTN-NuVasive Specialized Orthopaedics Inc) has recently been introduced as a treatment method for segmental tibial bone defects. This innovation provides promise in the management of segmental bone defects because it negates numerous complications associated with circular external fixation and the need for multiple implants when considering hybrid plate-assisted bone segment transport constructs. Given the novelty of the BTN, description of the surgical application and patient outcome measures are scarce in the current literature. To date, we have treated 4 patients with an average age of 27 years (range 19-44 years) using the BTN for segmental tibial defects ranging from 50 to 128 mm. We have accumulated data over an average follow-up of 18.07 months (range 12.96-25.13 months), demonstrating good patient tolerance of the device. Three patients successfully completed their treatment course with a calculated average bone healing index of 41.4 days/cm (range 31.41-54.82 days/cm). One patient was noted to experience an asymptomatic docking site nonunion requiring subsequent surgery for nonunion repair. Implant-associated complications included symptomatic implant, axial malalignment, docking site nonunion, and external remote control technical malfunction. Injury-related complications were encountered and noted to include: superficial infection, wound dehiscence, peroneal tendonitis, and joint rigidity. In this study, the authors present a case series using this implant to date and discuss our experiences with the BTN with reference to clinical indications, tibial bone preparation, BTN implantation, transport protocol, docking site procedure, and clinical/radiographic outcomes.

Treatment patterns of ABOS part II candidates: A decline of operative management among geriatric proximal humerus fractures over the decade (2010-2020).

BACKGROUND: The purpose of this study was to assess trends in ABOS part II candidate's operative management of geriatric (≥65 years) proximal humerus fractures over the 2010-2020 decade. METHODS: This retrospective database cohort study utilized the American Board of Orthopaedic Surgery (ABOS) database for candidates taking Part II of their boards. Surgical coding was reviewed and the ICD10 data was correlated to the CPT code for shoulder arthroplasty or open reduction internal fixation. We investigated the number of proximal humerus fracture operative cases per year, the percent arthroplasty used per year, the stratification of percent arthroplasty per orthopaedic fellowship subspecialty and geographic region. RESULTS: A total of 2,409 operative cases for proximal humerus fractures in patients 65 years of age and older were submitted by 1,420 ABOS candidates. There was a 37% reduction in operatively managed proximal humerus fractures among ABOS part II candidates between the first half of the decade (2010-2015, 263.2 +/- 13.4) and the second half of the decade (2016-2020, 166 +/- 31.2; p<.05). There also was a downward trend with a 53% reduction in percent treated with arthroplasty as compared to ORIF during those same windows (2010-2015, 34.4 +/-11.7) and (2016-2020, 16.2 +/- 6.4; p<.5). Partitioned by single fellowship training, Shoulder and Elbow (S&E) surgeons performed the highest percent arthroplasty at 25.2%, followed by Sports at 23.1% and the lowest percent arthroplasty was Trauma at 11.7%. The Southeast United States had the lowest percentage arthroplasty at 15.8% as compared to the Midwest (23.8%) and Northeast (25.8%). CONCLUSION: Despite the rapid growth of both the elderly population and related geriatric proximal humerus fractures, ABOS candidates are treating less with surgery. There has been approximately a 37% decrease in the total number of operatively treated proximal humerus fractures between the first and second half 2010-2020 decade. When operative treatment is performed, there is a trend towards ORIF over an arthroplasty. Trauma fellowship trained surgeons are less likely to perform an arthroplasty as compared to other subspecialties. The Southeast region is least likely to perform an arthroplasty as compared to the Midwest or Northeast.

Antibiotic cement-coated intramedullary nail is cost-effective for the initial treatment of GAâ ¢ open tibia fractures.

OBJECTIVE: To evaluate the cost-effectiveness of antibiotic cement-coated intramedullary nails (IMN) in the initial management of Gustilo-Anderson type Ⅲ (GAIII) open tibia fractures. METHODS: A break-even equation was used to analyze the costs associated with antibiotic cement-coated IMN and postoperative infection following GAⅢ open tibia fractures. This equation produced a new infection rate, which defines what percentage the antibiotic coated IMN needs to decrease the initial infection rate for its prophylactic use to be cost-effective. The postoperative infection rate used for calculations was 30%, a value established in current literature for these fracture types (6-33%). The institutional costs associated with a single operative debridement and resultant inpatient stay and treatment were determined. A sensitivity analysis was conducted to demonstrate how various total costs of infection and different infection rates affected the break-even rate, the absolute risk reduction (ARR), and the number needed to treat (NNT). RESULTS: Financial review yielded an average institutional cost of treating a postoperative infection to be $13,282.85. This number was inclusive of all procedures during an inpatient stay. The added cost of the antibiotic coated implant to the hospital is $743.42. Utilizing the break-even formula with these costs and a 30% initial infection rate, antibiotic coated IMN was economically viable if it decreased infection rate by 0.056% (NNT = 1,785.714). CONCLUSION: This break-even analysis model suggests the initial use of an antibiotic coated IMN in the setting of GAⅢ open tibia fractures is cost-effective.

Posttraumatic Soft Tissue Coverage of the Lower Leg for the Orthopedic Surgeon.

Soft tissue reconstructive techniques are powerful tools for the orthopedic surgeon caring for lower extremity trauma. This article seeks to inform orthopedic surgeons about useful techniques for skin closure, secondary wound closure techniques, and rotational flaps of the lower leg. Split thickness skin grafting, piecrusting, and the use of negative pressure wound therapy for skin closure, as well as rotational gastrocnemius, soleus, and reverse sural artery flaps are discussed with emphasis on techniques for the nonvascular and nonmicrovascular orthopedic surgeon.

Radiation Exposure Among Orthopaedic Trauma Surgeons: Deconstructing Commonly Held Myths and Misperceptions.

OBJECTIVES: To review and evaluate the validity of common perceptions and practices regarding radiation safety in orthopaedic trauma. DESIGN: Retrospective study. SETTING: Level 1 trauma center. SUBJECTS: N/A. INTERVENTION: The intervention involved personal protective equipment. MAIN OUTCOME MEASUREMENTS: The main outcome measurements included radiation dose estimates. RESULTS: Surgeon radiation exposure estimates performed at the level of the thyroid, chest, and pelvis demonstrate an estimated total annual exposure of 1521 mR, 2452 mR, and 1129 mR, respectively. In all cases, wearing lead provides a significant reduction (90% or better) in the amount of radiation exposure (in both radiation risk and levels of radiation reaching the body) received by the surgeon. Surgeons are inadequately protected from radiation exposure with noncircumferential lead. The commonly accepted notion that there is negligible exposure when standing greater than 6 feet from the radiation source is misleading, particularly when cumulative exposure is considered. Finally, we demonstrated that trauma surgeons specializing in pelvis and acetabular fracture care are at an increased risk of exposure to potentially dangerous levels of radiation, given the amount of radiation required for their caseload. CONCLUSION: Common myths and misperceptions regarding radiation in orthopaedic trauma are unfounded. Proper use of circumferential personal protective equipment is critical in preventing excess radiation exposure.

Occupational Outcomes and Return to Running After Operative Management of Lisfranc Injuries in a High-Demand Population.

Background: Literature evaluating outcomes following operative fixation of Lisfranc injuries has demonstrated high rates of chronic disability, particularly in those returning to prior levels of physical function. The purpose of this study is to evaluate the occupational outcomes and return to running after open reduction and internal fixation (ORIF) or arthrodesis for Lisfranc fracture-dislocations in a moderate- to high-demand military cohort. Methods: All active-duty servicemembers undergoing ORIF or primary arthrodesis (Current Procedural Terminology 28615 and 28730, respectively) for confirmed Lisfranc fracture-dislocations (International Classification of Diseases, Ninth Revision codes 838.03 or 838.13) with minimum 2-year follow-up were isolated from the Military Health System. Demographic and surgical variables were recorded. Return to military function, return to running, perioperative morbidity, and rates of reoperation for complication were the outcomes of interest. Univariate analysis followed by multivariate logistic regression determined the association between patient demographics, type of fracture fixation (ie, ORIF vs arthrodesis) and functional outcomes, including medical separation. Results: Among Lisfranc injuries, 64 patients underwent ORIF while 6 underwent primary arthrodeses with a mean age of 28.1 years. At mean follow-up of 3.5 years (range, 2.0-6.3 years), 20% of servicemembers underwent medical separation due to limitations related to their injuries. body mass index (BMI) ≥30 kg/m2 (OR 17.67; 95% CI, 3.69-84.53) and Army or Marines service branch (OR 3.86; 95% CI, 1.08-13.86) were significant independent predictors for medical separation. Among servicemembers undergoing ORIF or primary arthrodeses, 69% returned to occupationally required daily running during the follow-up period. Servicemembers with a BMI <30 kg/m2 were more likely to return to running (OR 13.14, 95% CI, 2.50-69.19). Radiographic evidence of posttraumatic Lisfranc osteoarthritis occurred in 10 (16%) servicemembers who underwent internal fixation, and 82% of ORIF patients underwent implant removal. Conclusions: At mean 3.5-year follow-up, 80% of servicemembers undergoing ORIF or primary arthrodeses for Lisfranc injuries remained on active duty or successfully completed their military service, and 69% were able to resume occupationally required daily running. Surgeons should preoperatively counsel patients with these injuries on the possibility of persistent long-term disability.Levels of Evidence: Level IV: Retrospective series.

There Is No Role for Damage Control Orthopedics Within the Golden Hour.

INTRODUCTION: Trauma systems within the United States have adapted the "golden hour" principle to guide prehospital planning with the goal to deliver the injured to the trauma facility in under 60 minutes. In an effort to reduce preventable prehospital death, in 2009, Secretary of Defense Robert M. Gates mandated that prehospital transport of injured combat casualties must be less than 60 minutes. The U.S. Military has implemented a 60-minute timeline for the transport of battlefield causalities to medical teams to include Forward Surgical Teams and Forward Resuscitative Surgical Teams. The inclusion of orthopedic surgeons on Forward Surgical Teams has been extrapolated from the concept of damage control orthopedics (DCO). However, it is not clear if orthopedic surgeons have yielded a demonstrable benefit in morbidity or mortality reduction. The purpose of this article is to investigate the function of orthopedic surgeons during the military "golden hour." MATERIALS AND METHODS: The English literature was reviewed for evidence supporting the use of orthopedic surgeons within the golden hour. Literature was reviewed in light of the 2009 golden hour mandate by Secretary Gates as well as those papers which highlighted the utility of DCO within the golden hour. RESULTS: Evidence for orthopedic surgery within the "golden hour" or in the current conflicts when the United States enjoys air superiority was not identified. CONCLUSIONS: Within the military context, DCO, specifically pertaining to fracture fixation, should not be considered an element of golden hour planning and thus orthopedic surgeons are best utilized at more centralized Role 3 facility locations. The focus within the first hour after injury on the battlefield should be maintained on rapid and effective prehospital care combined with timely evacuation, as these are the most critical factors to reducing mortality.

A future with no MVC patients? Impact of autonomous vehicles on orthopaedic trauma may be slow and steady.

INTRODUCTION: Orthopaedic trauma results in significant patient morbidity. Autonomous vehicle (AV) companies have invested over $100 billion in product development. Successful AVs are projected to reduce motor vehicle collision (MVC)-related injuries by 94%. The purpose of this study was to estimate the timing and magnitude of AV impact on orthopaedic trauma volume. METHODS: ICD 9 codes consistent with acetabulum (OTA 62), pelvis (OTA 61), hip (OTA 31), femur (OTA 32-33), tibia (OTA 41-43), ankle (OTA 44), and calcaneus (OTA 82) fractures and the proportion of cases caused by MVC were taken from the National Trauma Databank (NTDB) 2009-2016. Regression was performed on estimates of market penetration for autonomous vehicles taken from the literature. RESULTS: For NTDB years 2009 to 2016, 300,233 of 987,610 fractures of interest were the result of MVC (30.4%). However, the percentage of MVC mechanism of injury ranged from 9% to 53% depending on fracture type. Regression of estimates of AV market penetration predicted an increase of 2.2% market share per year. In the next 15 years we project 22% market penetration resulting in a 6% reduction in orthopaedic lower extremity trauma volume. CONCLUSION: Adoption of AVs will result in a projected 8% reduction in MVC-related orthopaedic trauma-related injuries over a 15-year period. Although this represents a significant reduction in morbidity, the advent of AVs will not eliminate the need for robust orthopaedic trauma programs. The gradual rate of injury reduction will allow hospitals to adapt and reallocate resources accordingly.

Early Stabilization of Femur Fractures in the Setting of Polytrauma Is Associated With Decreased Risk of Pulmonary Complications and Mortality.

Timing of definitive fixation of femoral shaft fractures is a subject of continued controversy. The purpose of this study was to determine if early definitive fixation of femoral shaft fractures in the setting of polytrauma decreased the risk of pulmonary complications and mortality. The 2009-2012 National Sample Program of the National Trauma Data Bank was queried for all patients 18 to 65 years with Injury Severity Scores (ISS) >15 who underwent definitive fixation of femoral shaft fractures. Mortality, perioperative complications, and length of intensive care unit (ICU) and hospital stay were the primary outcome measures of interest. Following multivariate analyses, increased time to surgery was found to portend a statistically significant increased risk of acute respiratory distress syndrome(ARDS), mean ventilator time, length of ICU and hospital stay, and mortality. Earlier definitive fixation of femoral shaft fractures in the setting of polytrauma is associated with significantly decreased risk of ARDS, mean ventilator time, length of ICU and hospital stay, and mortality. (Journal of Surgical Orthopaedic Advances 28(2):137-143, 2019).

Mortality effects of timing alternatives for hip fracture surgery.

BACKGROUND: The appropriate timing of hip fracture surgery remains a matter of debate. We sought to estimate the effect of changes in timing policy and the proportion of deaths attributable to surgical delay. METHODS: We obtained discharge abstracts from the Canadian Institute for Health Information for hip fracture surgery in Canada (excluding Quebec) between 2004 and 2012. We estimated the expected population-average risks of inpatient death within 30 days if patients were surgically treated on day of admission, inpatient day 2, day 3 or after day 3. We weighted observations with the inverse propensity score of surgical timing according to confounders selected from a causal diagram. RESULTS: Of 139 119 medically stable patients with hip fracture who were aged 65 years or older, 32 120 (23.1%) underwent surgery on admission day, 60 505 (43.5%) on inpatient day 2, 29 236 (21.0%) on day 3 and 17 258 (12.4%) after day 3. Cumulative 30-day in-hospital mortality was 4.9% among patients who were surgically treated on admission day, increasing to 6.9% for surgery done after day 3. We projected an additional 10.9 (95% confidence interval [CI] 6.8 to 15.1) deaths per 1000 surgeries if all surgeries were done after inpatient day 3 instead of admission day. The attributable proportion of deaths for delays beyond inpatient day 2 was 16.5% (95% CI 12.0% to 21.0%). INTERPRETATION: Surgery on admission day or the following day was estimated to reduce postoperative mortality among medically stable patients with hip fracture. Hospitals should expedite operating room access for patients whose surgery has already been delayed for nonmedical reasons.

Predictors of Acute Complications Following Traumatic Upper Extremity Amputation.

Current literature is deficient in its description of acute complications following major traumatic upper extremity amputations (UEAs). This study sought to identify acute complications following major UEAs by the 2009-2012 National Trauma Databank to extract demographics, comorbidities, concomitant injuries, and surgical characteristics for major traumatic UEA patients. Multivariate analyses identified significant predictors of mortality and major systemic complications. Major traumatic upper extremity amputations were identified in 1190 patients. Major systemic complications occurred in 13% of patients and most often involved pulmonary (7.4%) or renal (4.7%) systems. Overall in-hospital mortality rate was 11%. Male sex, prehospital systolic blood pressure less than 90, Injury Severity Score > 16, and initial Glasgow Coma Scale > 8 were risk factors for complications or in-hospital mortality. Acute replantation was performed in 0.12%. Systemic complications following major traumatic UEA typically affect the pulmonary system. Injury or patient-dependent factors did not influence acute treatment with revision amputation versus replantation. (Journal of Surgical Orthopaedic Advances 27(2):113-118, 2018).

Open reduction and internal fixation (ORIF) versus ORIF and primary subtalar arthrodesis for complex displaced intraarticular calcaneus fractures: An expected value decision analysis.

OBJECTIVES: To determine the optimal patient-oriented treatment between open reduction and internal fixation (ORIF) with or without primary subtalar arthrodesis (PSTA) for patients with displaced intraarticular calcaneus fractures (DIACFs, OTA 82-C3 and C4). DESIGN: Expected value decision analysis. SETTING: Academic military treatment facility. PARTICIPANTS: One hundred randomly selected volunteers. INTERVENTION: Hypothetical clinical scenario involving ORIF versus ORIF with PSTA. MAIN OUTCOME MEASUREMENTS: Decision analysis was used to elucidate the superior treatment option based on expected patient values, composed of: the product of the average outcome probabilities established by previously published studies and the average ascribed patient utility values for each outcome probability. One-way sensitivity analysis was performed to quantify the amount of change required for the inferior treatment to equal or surpass the superior option. RESULTS: Expected values for ORIF and ORIF with PSTA were 8.96 and 18.06, respectively, favoring ORIF with PSTA. One-way sensitivity analysis was performed by artificially decreasing the rate of secondary fusion following isolated ORIF thus increasing its overall expected value. Adjusting the rate of secondary fusion to 0%, the expected value of ORIF with PSTA nearly doubled that of ORIF (18.06 vs 9.45). Similarly, when adjusting the moderate and severe complication rates following ORIF with PSTA to 100%, the expected value of ORIF with PSTA still exceeded that of ORIF (15.45 vs 8.96, and 13.52 vs 8.96, respectively). CONCLUSION: Expected value decision analysis favors ORIF with PSTA as the optimal treatment for complex DIACF.

Comparison of Calcaneal Exposure Through the Extensile Lateral and Sinus Tarsi Approaches.

The purpose of this study was to compare the exposure of the posterior facet with the extensile lateral (EL) approach compared with the sinus tarsi (ST) approach. We hypothesized that the ST approach will provide a similar exposure of the posterior calcaneal facet. A total of 8 sequential ST then EL approaches were performed on cadavers. Calcaneal landmarks were identified by visualization or palpation. Calibrated digital photographs of the posterior facet and lateral calcaneal body were obtained from standardized positions and used to calculate the exposed surface area. No significant difference was found in the average square area of the posterior facet exposed with the 2 approaches. Significantly more of the lateral calcaneal body was seen with the EL approach. Excluding the posterior facet superomedial quadrant, all the landmarks were visualized in 100% of approaches. The superomedial corner was visualized in significantly more of the cadavers with the EL approach and was palpable in 12.5% of the remaining cadavers in both approaches. Whereas the ST approach exposes less of the lateral wall of the calcaneus, it exposes similar amounts of the posterior facet when compared with the EL approach. LEVELS OF EVIDENCE: Therapeutic, Level V.
