Differences in Risk Factors for Rotator Cuff Tears in Young Versus Old Individuals.

Background The etiology of rotator cuff tears is thought to be multifactorial with current literature that varies with regard to identifiable risk factors. The purpose of this retrospective review was to identify risk factors for full-thickness rotator cuff tears and determine whether they differ in young versus older individuals. Methods To determine the presence or absence of a rotator cuff tear, 1,561 patients with a shoulder MRI were reviewed. If a tear was present, it was further classified into a partial or full-thickness tear. Demographic variables and clinical data were collected and analyzed with a two-sided Student's t-test or Wilcoxon rank sum test for continuous variables and a Chi-square test or Fisher's exact test for categorical variables. Age and BMI were dichotomized using receiver operator curves. Results Charlson Comorbidity Index, age, BMI, sex, race, and work status were all factors that variably affected a patient's risk of experiencing a rotator cuff tear, with different factors carrying more influence on outcomes within those who are older versus those who are younger. Gender and race were found to differ as risk factors between young and older individuals. Conclusion We were able to identify risk factors overall associated with increased odds of sustaining a full-thickness rotator cuff tear. Our analyses also showed differences in the effect of gender and race as risk factors between young and older patients with rotator cuff tears. This finding may aid clinicians in counseling patients on more specific risks for their given age.

Accuracy of Clinical Suspicion for Rotator Cuff Tears by Orthopedic Surgeons When MRI Was Ordered on Initial Visits: Should Physical Therapy Be Mandated by Insurance Before MRI?

INTRODUCTION: Insurance companies often mandate six weeks of physical therapy (PT) prior to approving MRIs for patients with atraumatic rotator cuff (RTC) tears. While this is designed to limit unnecessary imaging orders, it can increase healthcare costs and delay diagnosis and surgery. This study investigated the incidence of full- and partial-thickness tears when an MRI was ordered at the time of initial consultation for shoulder pain by an orthopedic provider. METHODS: A retrospective review of patients who had an MRI ordered upon initial orthopedic consultation for chronic shoulder pain was conducted. The primary outcome measured was the presence of RTC tears as determined by the MRI report. The cost of six weeks of PT versus the cost of immediate MRI in these patients was collected from our institution's financial database. ANOVA, independent T-test, and chi-square test were used to analyze the differences between groups. RESULTS: A total of 365 patients were included. There were no significant differences in demographics between patients with full, partial, or no tears, with the exception that patients with full-thickness tears were older. Specifically, 43.0% had a full-thickness tear, 24.7% had a partial-thickness tear, and 32.2% had no tear on MRI. A total of 56.1% of the full-thickness tears proceeded to surgery. The cost of an upper extremity MRI without contrast averages $2,268, while two sessions of PT per week for six weeks totals $2,328. DISCUSSION: Over 67% of MRI orders yielded a positive finding of an RTC tear and remained at 67.2% in the absence of a history of conservative treatment, validating a specialist's clinical suspicion for an RTC tear and indication for MRI. Pre-MRI PT to satisfy insurance requirements may therefore delay intervention and increase healthcare costs when an orthopedic provider believes an MRI is warranted for clinical decision-making.

Educational and Clinical Outcome Measures in an Integrated Hand Service.

Background: We recently sought to integrate our orthopaedic and plastic hand surgeons with the goal of improving education, patient care, and providing seamless, continuous coverage for our trauma center. Our hypothesis was that integration could serve both the orthopaedic and plastic surgery training programs well and provide more consistent care for the trauma patients. Materials and Methods: Program director approval was granted for blinded analysis of case logs from plastic and orthopaedic surgery programs from 2012 through 2019. Data on mean and total number of hand cases were analyzed and compared for both specialties. Institutional Review Board approval was granted for a retrospective review of patient outcomes. Results: For both orthopaedic and plastics resident trainees, the mean number of hand cases increased during this study period suggesting that the integration had a favorable impact on both programs. The mean number of hand cases for orthopaedic residents rose from 163 to 246. The mean number of hand cases for plastic surgery residents rose from 218 to 295. Patient outcomes as reflected in length of stay and time to consultation also improved. Conclusion: To improve hand surgical training and patient care, an integrated orthoplastics approach to hand surgery was implemented at our institution. Plastic surgery trainees are completing more hand surgery cases in an integrated model (p < 0.001), including fracture care (p < 0.047). Orthopaedic surgery trainees have doubled the percentage of integumentary and microsurgery cases in the integrated model (p < 0.001). The educational and clinical changes affected in an integrated model have changed the paradigm for educating future hand surgeons at our institution.
