Technique and Early Outcomes for High-Energy Calcaneus Fractures Treated With Staged External Fixation to Combined Open Reduction Internal Fixation and Subtalar Arthrodesis.

OBJECTIVE: (1) To present an effective surgical technique for the treatment of open and high-energy calcaneal fractures with significant soft tissue injuries. (2) To present complications with this technique and to evaluate patient-reported outcomes of staged external fixation followed by delayed reconstruction with open reduction internal fixation (ORIF) and subtalar arthrodesis. DESIGN: Retrospective case series. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: Twelve patients with 13 calcaneus fractures associated with open traumatic wounds (10 patients) or other severe soft tissue injury (ie, fracture blisters) between April 2013 and December 2019. INTERVENTION: All patients were treated with staged ankle-spanning external fixation and delayed reconstruction with ORIF with subtalar arthrodesis. MAIN OUTCOME MEASURES: Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes are presented via the domains of physical function (PF), pain interference (PI), and depression (D) in addition to visual analog score. Complications with the injury and surgical procedure were reported as well. RESULTS: Patients underwent initial stabilization on average 1.3 days (range, 0-12 days) from injury with stage II occurring on average 31.1 days (range, 18-42 days) from external fixation. Mean time to radiographic union was 5.6 months (range, 4-10 months). One-year mean PROMIS outcomes were as follows: PF final average of 37.4 with an average improvement of 12.2 (P < 0.01), PI final average of 62.2 with average improvement of 5.6 (P = 0.01), and D final average of 52.1 with average improvement of 6 (P = 0.12). Mean final visual analog score pain score was 3.6 with an average improvement of 2.25 (P = 0.01). CONCLUSION: Staged treatment with initial external fixation followed by ORIF and subtalar arthrodesis in the setting of highly comminuted calcaneus fractures with significant soft tissue compromise effectively addresses both bony and soft tissue concerns while providing for positive outcomes postoperatively with regards to pain and function. There were minimal complications noted for this complex injury. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Physical Function and Pain Interference Levels of Hallux Rigidus Patients Before and After Synthetic Cartilage Implant vs Arthrodesis Surgery.

BACKGROUND: Hallux rigidus is a common and painful degenerative condition of the great toe limiting a patient's physical function and quality of life. The purpose of this study was to investigate pre- and postoperative physical function (PF) and pain interference (PI) levels of patients undergoing synthetic cartilage implant hemiarthroplasty (SCI) vs arthrodesis (AD) for treatment of hallux rigidus using the Patient-Reported Outcomes Measurement Information System (PROMIS). METHODS: PROMIS PF and PI t scores were analyzed for patients who underwent either SCI or AD. Postoperative final PROMIS t scores were obtained via phone survey. Linear mixed model analysis was used to assess differences in PF and PI at each follow-up point. Final follow-up scores were analyzed using independent sample t tests. RESULTS: Total 181 (59 SCI, 122 AD) operatively managed patients were included for analysis of PROMIS scores. Final phone survey was performed at a minimum of 14 (mean 33, range, 14-59) months postoperatively, with 101 patients (40 SCI, 61 AD) successfully contacted. The mean final follow-up was significantly different for SCI and AD: 27 vs 38 months, respectively (P < .01). The mean age of the SCI cohort was lower than the AD cohort (57.5 vs 61.5 years old, P = .01). Average PF t scores were higher in the SCI cohort at baseline (47.1 and 43.9, respectively, P = .01) and at final follow-up (51.4 vs 45.9, respectively, P < .01). A main effect of superior improvement in PF was noted in the SCI group (+4.3) vs the AD group (+2) across time intervals (P < .01). PI t scores were similar between the 2 procedures across time points. CONCLUSION: The SCI cohort reported slightly superior PF t scores preoperatively and at most follow-up time points compared with the arthrodesis group. No differences were found for PI or complication rates between the 2 treatment groups during this study time frame. LEVEL OF EVIDENCE: Level IV, case series.

Talar Avascular Necrosis After Calcium Phosphate Injection Treatment of Talar Bone Marrow Lesions: A Report of 2 Cases.

CASE: We report on 2 patients who developed avascular necrosis (AVN) of the talus and poor patient outcomes after undergoing calcium phosphate injection into talar dome bone marrow lesions. CONCLUSION: Subchondroplasty, defined as calcium phosphate injection for the treatment of articular bone marrow edema, is a recently described procedure for use in the ankle joint. In our opinion, the limited available research is of poor quality and describes equivocal improvement in patient symptoms after this procedure. Given the debilitating outcomes and extensive AVN we observed in 2 patients, we strongly advise caution in the use of this procedure in the talus.

Immediate Improvement in Physical Function After Symptomatic Syndesmotic Screw Removal.

OBJECTIVE: To investigate the immediate impact of removing symptomatic syndesmotic screws on PROMIS outcomes and ankle range of motion (ROM) in patients who had previously undergone ankle fracture open reduction and internal fixation (ORIF) and syndesmotic fixation and later experienced functional limitations. DESIGN: Prospective cohort study. SETTING: Level 1-trauma center. PATIENTS/PARTICIPANTS: Fifty-eight patients with ankle fractures with syndesmotic instability that required ORIF with syndesmotic fixation who underwent syndesmotic screw removal (SSR) and 71 patients who underwent ankle ORIF with syndesmotic fixation, but without screw removal during the same study period. INTERVENTION: Symptomatic SSR for patients with functional limitations and decreased ankle ROM. MAIN OUTCOME MEASUREMENTS: PROMIS physical function (PF) and pain interference T-scores and ankle ROM before and after screw removal. RESULTS: Patients who underwent SSR had a statistically significant improvement in the PF T-score to 44.5 (P < 0.01) in the early postoperative period (mean 48 days) after screw removal. The screw removal occurred an average of 184 days after initial ORIF. This PF T-score change also met the minimally clinically important difference. There was a trend toward a significant improvement in PF T-scores for the SSR group as compared to the cohort group (44.5 vs. 41.6; P = 0.06) after screw removal. Removal of symptomatic implants resulted in an early mean improvement of total arc ankle ROM by 17 degrees (P < 0.01). CONCLUSIONS: Patients experienced an immediate and significant improvement in PF outcomes and ankle ROM after symptomatic SSR for ankle fracture ORIF with syndesmotic fixation. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Pattern of recovery and outcomes of patient reported physical function and pain interference after ankle fusion: a retrospective cohort study.

BACKGROUND: Research on outcomes after ankle fusion focuses on basic activities of daily living, fusion rates, and gait parameters. Little has been reported on the patient's perspective after surgery. The purpose of this study was to determine the change in patient reported physical function and pain interference after ankle fusion surgery to guide patient expectations and improve provider communication. METHODS: This was a retrospective review of prospectively collected patient reported outcome measurement information system (PROMIS) data in 88 ankle arthrodesis procedures performed from May 2015 to March 2018. The PROMIS Physical function (PF) and pain interference (PI) measures were collected as routine care. Linear mixed models were used to assess differences at each follow-up point for PF and PI. Preoperative to last follow-up in the 120-365 day interval was assessed using analysis of variance. Outcomes included T-scores, z-scores, and PROMIS-Preference (PROPr) utility scores for PF and PI and the percentage of patients improving by at least 4 T-score points. RESULTS: The linear mixed model analysis for PF after the 120-149 days, and for PI, after 90-119 days, indicated recovery plateaued at 39-40 for PF and 57-59 for PI T-scores. The change in the PI T-score was the greatest with a mean T-score improvement of - 5.4 (95% CI - 7.7 to - 3.1). The proportion of patients improving more than 4 points was 66.2% for either PF or PI or both. The change in utility T-scores for both PF (0.06, 95% CI 0.02 to 0.11) and PI (0.15, 95% CI 0.09 to 0.20) was significantly improved, however, only PI approached clinical significance. CONCLUSION: Average patients undergoing ankle fusion experience clinically meaningful improvement in pain more so than physical function. Average patient recovery showed progressive improvement in pain and function until the four-month postoperative time point. Traditional dogma states that recovery after an ankle fusion maximizes at a year, however based on the findings in this study, 4 months is a more accurate marker of recovery. A decline in function or an increase in pain after 4 months from surgery may help to predict nonunion and other complications after ankle arthrodesis. LEVEL OF EVIDENCE: Level II, prospective single cohort study.

Resident Independence Performing Common Orthopaedic Procedures at the End of Training: Perspective of the Graduated Resident.

BACKGROUND: The Accreditation Council for Graduate Medical Education (ACGME) has established minimum exposure rates for specific orthopaedic procedures during residency but has not established the achievement of competence at the end of training. The determination of independence performing surgical procedures remains undefined and may depend on the perspective of the observer. The purpose of this study was to understand the perceptions of recently graduated orthopaedic residents on the number of cases needed to achieve independence and on the ability to perform common orthopaedic procedures at the end of training. METHODS: We conducted a web survey of all 727 recently graduated U.S. orthopaedic residents sitting for the 2018 American Board of Orthopaedic Surgery Part I Examination in July 2018. The surveyed participants were asked to assess the ability to independently perform 26 common adult and pediatric orthopaedic procedures as well as to recommend the number of cases to achieve independence at the end of training. We compared these data to the ACGME Minimum Numbers and the average ACGME resident experience data for residents who graduated from 2010 to 2012. RESULTS: For 14 (78%) of the 18 adult procedures, >80% of respondents reported the ability to perform independently, and for 7 (88%) of the 8 pediatric procedures, >90% reported the ability to perform independently. The resident-recommended number of cases for independence was greater than the ACGME Minimum Numbers for all but 1 adult procedure. For 18 of the 26 adult and pediatric procedures, the mean 2010 to 2012 graduated resident exposure was significantly less than the mean number recommended for independence by 2018 graduates (p < 0.05). CONCLUSIONS: Overall, recently graduated residents reported high self-perceived independence in performing the majority of the common adult and pediatric orthopaedic surgical procedures included in this study. In general, recently graduated residents recommended a greater number of case exposures to achieve independence than the ACGME Minimum Numbers.

Perceptions of the Recommended Resident Experience with Common Orthopaedic Procedures: A Survey of Program Directors and Early Practice Surgeons.

BACKGROUND: U.S. orthopaedic residency training is anchored by the Accreditation Council for Graduate Medical Education (ACGME) requirements, which include minimum numbers for 15 categories of procedures. The face validity of these recommendations and expectations for exposure to other common procedures has not been rigorously investigated. The main goals of this investigation were to understand the perceptions of program directors and early practice surgeons regarding the number of cases needed in residency training and to report which of the most commonly performed procedures residents should be able to perform independently upon graduation. METHODS: We sent surveys to 157 current program directors of ACMGE-approved orthopaedic surgery residency programs and to all examinees sitting for the American Board of Orthopaedic Surgery (ABOS) Part II Oral Examination in 2017, requesting that they estimate the minimum number of exposures for the 22 adult and 24 pediatric procedures that are most commonly performed during residency and the first 2 years in practice. Where applicable, we compared these with the ACGME "Minimum Numbers" and the average ACGME resident experience data from 2010 to 2012 for resident graduates. For each of the 46 procedures, participants were asked if every orthopaedic resident should be able to independently perform the procedure upon graduation. We compared the percent for independence between the early practice surgeons and the program directors. RESULTS: For the majority of adult and pediatric procedures, the early practitioners reported significantly higher numbers of cases needing to be performed during residency than the program directors. ACGME Minimum Numbers were always lower than the case numbers that were recommended by the early practice surgeons and the program directors. Overall we found good-to-excellent agreement for independence at graduation between program directors and early practitioners for adult cases (intraclass correlation coefficient [ICC], 0.98; 95% confidence interval [CI], 0.82 to 0.99) and moderate-to-good agreement for pediatric cases (ICC, 0.96; 95% CI, 0.74, 0.99). CONCLUSIONS: The program directors frequently perceived the need for resident operative case exposure to common orthopaedic procedures to be lower than that estimated by the early practice surgeons. Both program directors and early practice surgeons generally agreed on which common cases residents should be able to perform independently by graduation.

Operative Experience During Orthopaedic Residency Compared with Early Practice in the U.S.

BACKGROUND: The goal of surgical education is to prepare the trainee for independent practice; however, the relevance of the current residency experience to practice remains uncertain. The purpose of this study was to identify the surgical procedures most frequently performed in orthopaedic residency and in early surgical practice and to identify surgical procedures performed more often or less often in orthopaedic residency compared with early surgical practice. METHODS: This retrospective cohort study included American Medical Association (AMA) Current Procedural Terminology (CPT) codes (n = 4,329,561 procedures) reported by all U.S. orthopaedic surgery residents completing residency between 2010 and 2012 (n = 1,978) and AMA CPT codes for all procedures (n = 413,370) reported by U.S. orthopaedic surgeons who took the American Board of Orthopaedic Surgery Part II certifying examination between 2013 and 2015 (n = 2,205). Relative rates were determined for AMA CPT codes and AMA CPT code categories for adult and pediatric surgeries that had frequencies of ≥0.1% for both practitioners and residents. RESULTS: The top 25 adult AMA CPT code categories contributed 82.1% of the total case volume for residents and 82.4% for practitioners. Knee and shoulder arthroscopy were the most frequently performed procedures in adults in both residency and early practice. Humerus/elbow fracture and/or dislocation procedures and "other musculoskeletal-introduction or removal" procedures were the most frequently performed procedures in pediatric cases in both residency and early practice. Of the total 78 adult and 82 pediatric code categories included in our analysis that had a frequency of >1% in residency or early practice, there were 4 adult and 6 pediatric code categories demonstrating 44% to 1,164% greater frequency in residency than in early practice, and there were 8 adult and 7 pediatric code categories demonstrating 26% to 73% less frequency in residency than in early practice. CONCLUSIONS: Similarity between residency and early practice experience is generally strong. However, we identified several AMA CPT code categories and individual CPT codes for which the level of exposure during residency varied substantially from early practice experience. These findings can help residencies ensure adequate trainee exposure to procedures performed commonly in early practice.

Press Ganey Outpatient Medical Practice Survey Scores Do Not Correlate With Patient-Reported Outcomes After Primary Joint Arthroplasty.

BACKGROUND: Patient delivery of care satisfaction surveys have emerged as instruments to assess the quality of health care at both the hospital and provider levels. We evaluated the correlation between these care satisfaction surveys and patient-reported outcomes (PROs). METHODS: We reviewed secondary data on 540 patients with 540 random visits who underwent primary total joint arthroplasty between January 2014 and February 2017. The Press Ganey Outpatient Medical Practice Survey was collected from outpatient clinical encounters to measure patient satisfaction with their experience and matched to PRO measures from the same encounter. The PROs evaluated included the Patient-Reported Outcomes Measurement Information System physical function computerized adaptive test, v1.2, and the Patient-Reported Outcomes Measurement Information System Global 10 health survey. In addition to the random selection, we reviewed separate cross-sections of the data including preoperative visits within 90 days of the index procedure, all postoperative visits at least 1 year from the index procedure, and the magnitude of change in PRO scores from preoperative to a minimum 1-year postoperative visit. Data were evaluated using the Spearman correlation coefficient (rs). RESULTS: There was little if any correlation between the Press Ganey scores and PROs at all time points evaluated (all, rs: -0.13 to 0.14). When evaluating knee and hip arthroplasty cases separately, the data demonstrated similar results (all, rs: -0.33 to 0.18). CONCLUSION: We found little, if any, correlation between a patient's satisfaction with their care experience and their own perception of physical function and global health measures at all time points evaluated. These data question the utility of these scores as surrogate measures of health care quality, especially when reimbursements become tied to these metrics.

Treated Versus Untreated Depression in Total Joint Arthroplasty Impacts Outcomes.

BACKGROUND: To determine if there was a difference in the change in patient-reported physical function (PF) between nondepressed and medically treated depressed or untreated depressed total joint arthroplasty (TJA) patients. METHODS: This is an Institutional Review Board exempt retrospective review of 280 TJA cases from March 2014 to May 2016. Patient-reported PF was measured as part of the routine care via the Patient Reported Outcomes Measurement Information System PF computerized adaptive test. Linear generalized estimating equation regression analyses were used. RESULTS: Untreated depressed cases demonstrated much smaller gains in PF scores compared to nondepressed patients (P = .020). Additionally, although treated and untreated depressed patients had statistically similar preoperative and postoperative PF scores (P > .05), untreated depressed cases experienced a lower magnitude of change (P = .015). CONCLUSION: Medically treated depressed patients may have similar PF gains as nondepressed patients. Larger prospective studies may help identify whether screening for untreated depression and subsequent treatment leads to improved outcomes.

Multimodal Analgesia in Foot and Ankle Surgery.

Progress in surgical acute pain management has allowed most foot and ankle surgery to be performed in ambulatory outpatient surgical centers. Multimodal analgesia focuses on improving postoperative pain by combining pharmacologic and other modalities, addressing multiple pain mechanisms and receptor pathways while reducing adverse effects through lower doses of oral medications. Local anesthesia techniques provide excellent pain relief with few adverse events. Multimodal analgesia in foot and ankle surgery provides superior pain relief, and reduced opioid dependence and opioid-related side effects, improving patient satisfaction, safety, and timely return to function.

A Scaphoid Stress Fracture in a Female Collegiate-Level Shot-Putter and Review of the Literature.

Scaphoid stress fractures are rare injuries that have been described in young, high-level athletes who exhibit repetitive loading with the wrist in extension. We present a case of an occult scaphoid stress fracture in a 22-year-old female Division I collegiate shot-putter. She was successfully treated with immobilization in a thumb spica splint for 6 weeks. Loaded wrist extension activities can predispose certain high-level athletes to sustain scaphoid stress fractures, and a high index of suspicion in this patient population may aid prompt diagnosis and management of this rare injury.

Predicting excessive hemorrhage in adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion.

BACKGROUND CONTEXT: Blood loss in patients with adolescent idiopathic scoliosis (AIS) who are undergoing posterior spinal instrumentation and fusion (PSIF) varies greatly. The reason for this wide range is not clear. There are reports of unexpected massive hemorrhage during these surgeries. Many studies reflect authors' preferences for describing blood loss in terms of levels fused, weight, or percent blood volume. PURPOSE: We sought to define excessive blood loss clinically, determine its incidence in our study population, and identify associated variables. Results are intended to inform perioperative preparation for these cases. Results may be used to inform prospective study designs. STUDY DESIGN: This was a retrospective uncontrolled case series. PATIENT SAMPLE: A total of 311 consecutive AIS PSIF cases during the years 2005-2010 performed at Children's Hospital Colorado were studied. OUTCOME MEASURES: We measured estimated blood loss (EBL) and its association with multiple patient, surgical, and anesthetic variables. METHODS: Thirty-one variables potentially related to blood loss were collected retrospectively from electronic medical records for analysis. When no cases of clearly excessive blood loss were identified on the basis of visual examination of EBL distribution, we chose to use the top 10% of blood loss cases as an arbitrary determinant of excessive blood loss. Three cut-off strategies captured the top 10% of EBL cases with little variation in who was selected: 1) >1,700 mL of EBL, 2) >50% EBL/estimated blood volume, and 3) >150 mL/level fused EBL. Variables were compared with the χ(2) test, Fisher exact, or t-tests, when appropriate. A generalized linear mixed logistic model was used to determine the probability of excessive blood loss based on the number of levels fused. RESULTS: The average EBL was 89.17 mL/level fused (range, 45-133 mL). EBL fit a progressively wider distribution as surgical complexity (number of levels fused) increased. Number of levels fused (p<.0001), operative time (p=.0139), number of screws (p<.0001), and maximal preoperative Cobb angle (p=.0491) were significantly associated with excessive blood loss. The variable that was most strongly associated with excessive blood loss was the number of levels fused, with ≥12 levels having a probability of >10% of excessive hemorrhage. CONCLUSION: Excessive blood loss may be an arbitrary number until future research suggests otherwise. We show that the probability of exceeding one of our arbitrary definitions is approximately 10% when 12 or more levels are fused. If a 10% incidence of excessive blood loss is determined to be clinically relevant, teams might wish to pursue hematologic consultation and maximal blood conservation strategy when 12 or more levels are planned for fusion.
