Surgical treatment and outcomes of trans-ulnar basal coronoid fracture-dislocations.

BACKGROUND: Trans-ulnar fracture-dislocations of the elbow are complex injuries that can be difficult to classify and treat. Trans-ulnar basal coronoid injuries, in which the coronoid is not attached to either the olecranon or the metaphysis, present substantial challenges to achieve anatomic reduction and stable internal fixation. The purpose of this study was to analyze the outcome of surgical treatment of trans-ulnar basal coronoid fracture-dislocations. MATERIALS AND METHODS: Between 2002 and 2019, 32 consecutive trans-ulnar basal coronoid fracture-dislocations underwent open reduction and internal fixation at our institution. Four elbows were lost to follow-up within the first 6 months after surgery and were excluded. Among the 28 elbows remaining, there were 13 females and 15 males with a mean age of 56 (range 28-78) years at the time of injury. The mean clinical and radiographic follow-up times were 37 months and 29 months, respectively. Radiographs were reviewed to determine rates of union, Hastings and Graham heterotopic ossification (HO) grade, and Broberg and Morrey arthritis grade. RESULTS: Union occurred in 25 elbows. Union could not be determined for 1 elbow at most recent follow-up and the remaining 2 elbows developed nonunion of the coronoid. Complications occurred in 10 elbows (36%): deep infection (4), ulnar neuropathy (2), elbow contracture (2), and nonunion (2). There were reoperations in 11 elbows (39%): irrigation and débridement with hardware removal (4), hardware removal (2), ulnar nerve transposition (2), contracture release with HO removal (2), and revision with iliac crest autograft (1). At most recent follow-up, the mean flexion-extension arc was 106° (range 10°-150°), and the mean pronation-supination arc was 137° (range 0°-170°). The mean Quick Disabilities of Arm, Shoulder, and Hand score was 11 (range 0-39) points with a mean Single Assessment Numeric Evaluation-Elbow score of 81 (range 55-100) points. At final radiographic follow-up, 16 elbows (57%) had HO (8 class I and 8 class II), and 20 elbows (71%) had arthritis (8 grade 1, 6 grade 2, and 6 grade 3). DISCUSSION: Trans-ulnar basal coronoid fracture-dislocations are severe injuries associated with high rates of reoperation, HO, and post-traumatic arthritis. However, the majority of elbows achieve union, a functional range of motion, and reasonable patient reported outcome measures. Over the study period, surgeons were more likely to utilize multiple deep approaches and separate fixation of the coronoid (either with lag screws or anteromedial plates) to ensure anatomic reduction.

Cannulated Screws or Hemiarthroplasty for Femoral Neck Fractures: Is There a Mortality Difference?

OBJECTIVES: To determine the difference in mortality and reoperation rate between femoral neck fractures (FNFx) treated with cannulated screw fixation (CS) or hemiarthroplasty (HA). METHODS: Design: Retrospective study. SETTING: Institutional registry data from a single Level I trauma center. PATIENT SELECTION CRITERIA: Inclusion criteria were patients ≥60 years old with a FNFx (AO/OTA 31-B) who underwent primary operative treatment with a HA or CS. OUTCOME MEASURES AND COMPARISONS: Mortality and reoperation rates following primary operative treatment between patients treated with either hemiarthroplasty or cannulated screws. Kaplan-Meier survival curves were generated. Comparisons in the primary outcomes were made between the hemiarthroplasty or cannulated screw cohorts using univariate and multivariate analysis where appropriate. RESULTS: A total of 2,211 patients were included in the study (1,721 HA and 490 CS) and followed for an average of 34.5 months. The average age was 82.3 years (60-106 years) and predominantly female (66.3%). 1-year mortality was higher for the HA group compared to CS with a HR of 1.37 (p=0.03), however over the lifetime of patient or to final follow up, survival was not statistically significant with a RR of 0.95 95% CI, 0.83-1.1, p=0.97) The rate of reoperation at one year was lower for HA (5.0%) than for CS (10.1%), (HR 3.0, 95% CI, 2.1-4.34, p<0.0001). CONCLUSIONS: Patients with FNFx treated with hemiarthroplasty had the same risk of mortality as those patients treated with cannulated screws across lifetime of patients or until final follow up. There is no difference in mortality at the 30- and 90-day timepoint, but a significant difference in mortality at 1 year. Hemiarthroplasty treatment was associated with a significantly lower reoperation risk when compared to cannulated screws across the lifetime of the patient or until final follow up.

Assessing the Accuracy and Reliability of the Fluoroscopic Ruler for Comminuted Femur Fractures: A Cadaveric Study.

BACKGROUND: Fixation of comminuted femur fractures may result in limb length discrepancy. Intraoperative fluoroscopic measurement of the contra-lateral femur with a ruler is commonly performed to establish a reference for femoral length. No evidence regarding the reliability and accuracy of this technique exists. This study aimed to assess the accuracy and interrater reliability of a fluoroscopic ruler in obtaining correct femoral length in a comminuted femoral shaft fracture model. MATERIALS AND METHODS: Approximately 5 cm of bone was removed from the left femoral diaphyses of 8 cadavers. Seven orthopedic surgery residents and 2 attendings measured the length of the intact contralateral femur using a ruler under fluoroscopy. The ruler was then applied to the "fractured" femur with manual traction applied until femoral length matched the measured length of the contralateral femur. The resulting gap in the "fractured" femur was compared with the length of bone that had been resected. Data were analyzed using means, SDs, and intraclass correlation coefficients (ICCs). RESULTS: Fifty-seven measurements were collected. The mean difference between the measured fracture gap and the length of bone removed was 8.0±5.8 mm (range, 0-22 mm). Femoral length was accurate to 5 mm in 40% of cases, 10 mm in 70%, 15 mm in 81%, 20 mm in 98%, and 25 mm in 100%. The overall interrater reliability was poor (ICC, 0.11; 95% CI, 0.001-0.44). CONCLUSION: Despite poor interrater reliability, the fluoroscopic ruler resulted in a mean leg length discrepancy of 8.0±5.8 mm in this cadaveric study. [Orthopedics. 202x;4x(x):xx-xx.].

Predicting Immediate Lordosis Restoration After Anterior Lumbar Interbody Fusion and the Effect of Posterior Column Osteotomies.

OBJECTIVE: Anterior lumbar interbody fusion (ALIF) can be combined with posterior column osteotomies (PCOs) to maximize lordotic correction. This study compares radiographic changes in regional and segmental lordosis in patients undergoing ALIF with and without PCOs. METHODS: Patients >18 years old who underwent ALIF at 1 or 2 segments at a single institution (January 2014-July 2020) were included. Preoperative and postoperative radiographic parameters were determined, and a propensity-matched analysis was performed. RESULTS: Ninety-nine patients (53 [54%] men) underwent ALIF at 129 levels (mean [SD], 1.3 [0.46] levels; median [range] age, 61 [32-83] years). PCOs were performed in 13 (13%) patients at 19 (15%) segments. PCOs included 13 Schwab grade 1 and 6 grade 2 osteotomies. All measures, including lumbar lordosis, segmental lordosis, disc angle, and neural foramen height, increased significantly after surgery (P ≤ 0.003). In the propensity-matched analysis, PCO was associated with greater increases in lumbar lordosis (14.9° vs. 8.2°, P = 0.02), segmental lordosis (14.0° vs. 9.6°, P = 0.03), and disc angle (15.0° vs. 10.2°, P = 0.046). The change in disc angle more closely approximated the inherent lordosis of the cage when PCO was performed (94% vs. 62%, P = 0.004). CONCLUSIONS: Performing PCOs and ALIFs significantly increased the radiographic correction of overall and segmental lordosis in the selected patient cohort. The disc angle achieved with ALIF without PCOs was approximately 60% of the cage lordosis. The addition of PCO allowed for greater segmental compression, enabling the disc angle to reach nearly 100% of the inherent interbody cage lordosis.

Tranexamic Acid Administered at Time of Hospital Admission Does Not Decrease Transfusion Rates or Blood Loss for Extracapsular Hip Fractures: A Double-Blinded Randomized Clinical Trial.

OBJECTIVES: To evaluate tranexamic acid (TXA) when administered immediately on hospital presentation in patients with extracapsular peritrochanteric hip fractures to determine its effect on (1) transfusion rates, (2) estimated blood loss, and (3) complications. DESIGN: Prospective, double-blinded, randomized clinical trial. SETTING: Single-center, Level 1 trauma center. PATIENT SELECTION CRITERIA: All patients with isolated OTA/AO 31-A fracture patterns from 2018 to 2022 were eligible for inclusion. Study drug was administered in the emergency department at the time of presentation-1-g bolus over 10 minutes followed by a 1-g infusion over 8 hours. OUTCOME MEASURES AND COMPARISONS: The primary outcome was the rate of red blood cell transfusion hospital days 1-4. Secondary outcomes included estimated blood loss and complications including venous thromboembolic events, stroke, myocardial infarction, all-cause 90-day readmissions, and all-cause mortality. RESULTS: One hundred twenty-eight patients were included-64 patients were randomized to intravenous TXA and 64 patients to intravenous normal saline (ie, placebo). There was no difference in the rate of red blood cell transfusion between treatment arms between hospital days 1-4 (27% in the TXA arm vs. 31% in the placebo arm, P = 0.65). Patients randomized to placebo who required transfusion received a mean of 2.30 units compared with 1.94 units in the TXA cohort (P = 0.55). There was no difference in the estimated blood loss between hospital days 1-4. There was no difference in the incidence of postoperative complications including venous thromboembolic events, stroke, myocardial infarction, 90-day readmission, or death. CONCLUSIONS: The results of this study do not support the use of preoperative TXA for reducing blood loss for geriatric patients with extracapsular hip fractures. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Fracture Dislocations of the Glenohumeral Joint.

PURPOSE OF REVIEW: Proximal humerus fracture dislocations typically result from high-energy mechanisms and carry specific risks, technical challenges, and management considerations. It is vital for treating surgeons to understand the various indications, procedures, and complications involved with their treatment. RECENT FINDINGS: While these injuries are relatively rare in comparison with other categories of proximal humerus fractures, fracture dislocations of the proximal humerus require treating surgeons to consider patient age, activity level, injury pattern, and occasionally intra-operative findings to select the ideal treatment strategy for each injury. Proximal humerus fracture dislocations are complex injuries that require special considerations. This review summarizes recent literature regarding the evaluation and management of these injuries as well as the indications and surgical techniques for each treatment strategy. Thorough pre-operative patient evaluation and shared decision-making should be employed in all cases. While nonoperative management is uncommonly considered, open reduction and internal fixation (ORIF), hemiarthroplasty, and reverse total shoulder replacement are at the surgeon's disposal, each with their own indications and complication profile.

What Makes a 5-Star Orthopaedic Sports Medicine Surgeon? An Analysis of Positive Online Patient Reviews.

Background: The increased focus on patient satisfaction has led to growth in the use of physician rating websites. Purpose: To analyze the factors associated with online 5-star patient reviews for orthopaedic sports medicine surgeons. Study Design: Cross-sectional study. Methods: A total of 70 orthopaedic sports medicine surgeons were randomly selected from the AOSSM website. A search was performed for these surgeons on Yelp.com. All reviews other than 5 stars (of a possible 5 stars) were excluded from the study. Each review was categorized as referring to a surgical or nonsurgical aspect of care, and each comment within the review was categorized as being clinically or nonclinically related. Comments were further subcategorized by specific features such as bedside manner, clinical outcomes, and patient education. Categorical variables were analyzed using the chi-square test. Results: Overall, 400 five-star reviews were included in the study, comprising 1225 total positive comments. Of the 400 five-star reviews, 200 (50%) were from surgically treated patients, and 200 (50%) were from nonsurgically treated patients. Of the 1225 positive comments, 505 (41%) were clinically related, and 720 (59%) were nonclinical. The most common positive clinical comments were for clear treatment plans (191 reviews [48%]), good outcomes (173 reviews [43%]), and providing alternative treatment plans (55 reviews [14%]). The most common positive nonclinical comments were for good physician bedside manner (287 reviews [72%]), friendly/professional staff (194 reviews [49%]), and ease of scheduling (68 reviews [17%]). Conclusion: The majority of 5-star patient reviews left positive comments regarding nonclinical aspects of care such as physician bedside manner and friendly staff. The most common positive comments regarding clinical aspects concerned good outcomes and clear treatment plans. The overall most common positive comment, in both surgically and nonsurgically treated patients, referred to good bedside manner.

Characterizing Single-star Negative Online Reviews of Orthopaedic Trauma Association Members.

INTRODUCTION: The purpose of this study was to characterize factors that contribute to 1-star negative reviews regarding orthopaedic trauma surgeons. METHODS: A search was done for Orthopaedic Trauma Association members on Yelp.com , Healthgrade.com , and Vitals.com in New York, Boston, San Francisco, Los Angeles, Dallas, Phoenix, Seattle, Baltimore, Denver, Houston, Philadelphia, and Washington, DC. All single-star reviews (out of a possible 5 stars) were included in this study. Reviews were categorized as either clinical or nonclinical and then further subcategorized. Categorical variables were analyzed using a chi-square test. The rate ratio (the ratio of the rate for nonsurgical divided by surgical reviews) was determined for each category. RESULTS: Two hundred eighty-eight single-star reviews were included in the study, comprising 655 total complaints. Of all complaints, 274 (41.8%) were clinically related and 381 (58.2%) were nonclinical. Of the 288 single-star reviews, 96 (33.3%) were from surgically treated patients and 192 (66.7%) were from nonsurgical patients. Most complaints were in reference to nonclinical aspects of care such as physician bedside manner (173 reviews, 60%), not enough time spent with provider (58 reviews, 20%), and wait time (42 complaints, 15%). The most common clinical complaints were for complication (61 reviews, 21%), disagree with decision/plan (49 reviews, 17%), and uncontrolled pain (45 reviews, 16%). Surgical patients had a significantly higher rate of clinical complaints than nonsurgical patients (1.57 vs. 0.64 clinical complaints per review, P < 0.001). Nonsurgical patients had a significantly higher rate of nonclinical complaints than surgical patients (1.43 vs. 1.10 nonclinical complaints per review, P < 0.001). DISCUSSION: Most 1-star reviews referenced a nonclinical aspect of care with a physician's bedside manner being the most common complaint. Surgical patients were markedly more likely to reference a clinical aspect of care, such as complications or misdiagnosis compared with nonsurgical patients, who more commonly referenced nonclinical aspects of care.

The Use of the Piriformis Fossa Radiographic Landmark to Predict "In-Out-In" Placement of the Posterosuperior Femoral Neck Screw.

OBJECTIVES: To investigate the correlation between a screw's radiographic relationship to the piriformis fossa with position on CT in the clinical setting. METHODS: Intraoperative fluoroscopic images of patients treated with cannulated screw fixation of a femoral neck fracture, who also had a postoperative CT scan, were retrospectively evaluated by 4 fellowship-trained orthopaedic trauma surgeons. The posterosuperior screw on the AP fluoroscopic view was determined to be above the piriformis fossa (APF) or below the piriformis fossa (BPF). Using CT scan to determine IOI placement, the ability to predict IOI position based on fluoroscopic imaging was evaluated by calculating accuracy, sensitivity, specificity, and interobserver reliability. RESULTS: 73 patients met inclusion criteria. The incidence of IOI screw placement was 59% on CT evaluation. The use of the PF landmark accurately predicted CT findings in 89% of patients. A screw placed APF was 90% sensitive and 88% specific in predicting cortical breach, with near-perfect interobserver agreement (κ = 0.81). CONCLUSION: The use of the PF radiographic landmark is highly sensitive and specific in predicting the placement of an IOI posterosuperior femoral neck screw. LEVEL OF EVIDENCE: Diagnostic Level II.

Patella Fracture Fixation With Novel Wagon Wheel Construct Versus Tension-Band Construct: A Technical Trick.

SUMMARY: Internal fixation of patella fractures remains technically challenging. Cannulated screws with an anterior tension band have been associated with high rates of implant prominence, and fracture comminution can make appropriate application of a tension band impractical. We present the results of a novel technique using a transtendinous/transligamentous mini-fragment plate positioned peripherally around the patella with radially directed screws: termed the wagon-wheel (WW) construct. Compared with a cohort of fractures treated with cannulated screws with an anterior tension band, there was no difference in final range of motion and rate of nonunion. The WW construct had a significantly decreased incidence of symptomatic implants (5% vs. 32%, P = 0.02), rate of reoperation (9% vs. 38%, P = 0.018), dependency on gait aids (10% vs. 38%, P = 0.031), and a faster time to union (HR: 2.2; 95% CI, 1.28-3.95, P = 0.005). In summary, the WW was designed with the goal of obtaining peripheral plate fixation to maximize fragment-specific fixation while minimizing implant prominence. Patients treated with the WW demonstrated reduced rates of implant prominence and reoperation.

In National Collegiate Athletic Association Men's and Women's Soccer Athletes There Is a Low Rate of Lumbar Spine Injury, Women Suffer More Recurrent Injuries than Men, and Most Injuries Occur in the Preseason.

Purpose: To use the National Collegiate Athletic Association Injury Surveillance Program (NCAA-ISP) from the 2009-2010 through the 2014-2015 seasons to report lumbar spine injury rates, characteristics, and time lost from sport in soccer players. Methods: Characteristics of lumbar spine injuries by season, competition/practice, and time lost from sport were determined using the NCAA-ISP database. Rates of injury were calculated as the number of injuries divided by the number of athlete exposures (AEs). AEs are any athlete participation in a competition or practice. Incidence rate ratios (IRRs) were calculated to compare rates between event types and time of season. Injury proportion ratios (IPRs) were used to evaluate differences in injury rates between men and women. Results: The NCAA-ISP estimated 4,464 LSIs over 5 years. The rate of LSI in men was 2.1/10,000 AEs and 3.0/10,000 AEs in women. Women were 1.43 times more likely to suffer an LSI compared to men. Women were 2.15 times as likely to suffer an LSI in competition compared to in practice while men were 1.10 times as likely. Women were 2.15 times as likely to be injured in the preseason compared to the regular season, while men were 3.76 times as likely. Non-contact injuries were the most common cause of lumbar spine injuries (LSIs) in men (35%); however, contact injuries were more common in women (33%). Most athletes both male (57%) and female (59%) returned to play within 24 hours. Conclusion: This study provides information on the characteristics of LSIs in NCAA soccer. The overall injury rate to the lumbar spine is relatively low. Injury rates are highest in the preseason and in competition. Women suffer from more recurrent LSI's than men, and men acquired more injuries through non-contact mechanisms. More than one-half of athletes returned to sport within 24 hours.

Medicare Payment for Orthopaedic Oncology Procedures Over the Past 20 Years.

BACKGROUND: Medicare payment has been examined in a variety of medical and surgical specialties. This study examines Medicare payment in the subspecialty of orthopaedic oncology. METHODS: The Physician Fee Schedule Look-up Tool was used to obtain payment information from 2000 to 2020 for procedures related to orthopaedic oncology billed to Medicare. RESULTS: For the 38 included orthopaedic oncology procedures, inflation-adjusted Medicare payment decreased an average of 13.6% overall from 2000 to 2020. After adjusting for inflation, the payment for procedures related to spine and pelvis increased by 7.6%, procedures relating to limb salvage increased by 14.6%, procedures associated with the surgical management of complications decreased by 26.9%, and procedures relating to metastatic disease management decreased by 34.8%. CONCLUSION: Medicare payment has declined by 13.6% from 2000 to 2020. This variation in Medicare payment represents a difference in valuation of these procedures by the Centers for Medicare and Medicaid Services and could be used to direct healthcare policy.

Lower Back Injuries in NCAA Female Volleyball Athletes: A 5-Year Epidemiologic Characterization.

BACKGROUND: Although lower back injuries (LBIs) are common among National Collegiate Athletic Association (NCAA) female volleyball athletes, their incidence and etiology has not been well-defined. PURPOSE: To describe the epidemiology of LBIs in collegiate female volleyball athletes over a 5-year period from the academic years 2009 to 2010 and 2013 to 2014. STUDY DESIGN: Descriptive epidemiology study. METHODS: The incidence and characteristics of spine injuries were identified utilizing the NCAA Injury Surveillance Program database. Rates of injury were calculated as the number of injuries by the total number of athlete-exposures (AEs). AEs were defined as any student participation in any single NCAA-sanctioned practice or competition. The injury rate was computed as the number of injuries per the total number of AEs and reported as a ration of injuries per 10,000 exposures. The ratio was then reported as overall number as well as stratified for event, time of season, and athletic NCAA division. Incidence rate ratios were then calculated to compare rates between event type. Results with 95% CIs that did not include 1.0 were considered statistically significant. RESULTS: An estimated 3384 LBIs occurred in NCAA female volleyball players during this 5-year time frame. These LBIs occurred at a rate of 4.89 injuries per 10,000 AEs. LBIs were 2.76 times more likely in preseason when compared with regular season. More injuries occurred in practice (85%) when compared with competition (15%). The outside hitter and middle blocker were the most commonly position to sustain an LBI. Almost 70% of injuries were new injuries, and another 29% were recurrent injuries. The most common mechanism of injury was equally split between contact (50.4%) and overuse (45.5%) injuries, whereas the remaining mechanisms of injury were secondary for unknown reasons (4.14%). Most players returned to play within 24 hours (72.3%) followed by 1 to 6 days (16.4%), and finally 7 to 12 days (11.3%). No patient required surgical intervention. CONCLUSION: The rate of LBIs was high (4.89/10,000 AEs) and injuries commonly recurred (29.2%). Most injuries were new, with most athletes returning to play with 24 hours.
