Abstract

Background: Computer assisted planning without patient specific instrumentation may be utilized to guide reverse total shoulder arthroplasty baseplate placement. The purpose of this study was to determine the difference between planned and achieved inclination and retroversion correction with three-dimensional preoperative computer assisted planning in reverse total shoulder arthroplasty without patient specific instrumentation with bone grafting for severe glenoid erosion. Methods: Preoperative three-dimensional computer assisted planning without patient specific instrumentation was performed on 15 patients undergoing primary reverse total shoulder arthroplasty with glenoid bone grafting for severe glenoid erosion. On preoperative and immediate postoperative computed tomography slices, two-dimensional retroversion and inclination were measured. Preoperative three-dimensional baseline retroversion and inclination and planned postoperative three-dimensional retroversion and inclination were measured. Planned and achieved version and inclination changes were compared. Results: The planned and achieved retroversion corrections were 18° and 12°, respectively (p < 0.001). The planned and achieved inclination corrections were 11° and 11°, respectively (p = 0.803). Conclusions: Three-dimensional computer assisted planning without patient specific instrumentation in the setting of reverse total shoulder arthroplasty with severe glenoid erosion requiring bone grafting can accurately guide baseplate placement. All cases in which failure to correct retroversion or inclination within 10° of planning occurred in patients with severe erosion (B3 or E3 glenoids), therefore patient specific guides may be warranted in these cases to improve accuracy of implantation. Level of evidence: Level IV, retrospective case series. [ABSTRACT FROM AUTHOR]

Abstract

INTRODUCTION: The purpose of this study was to evaluate the psychometric properties of the Patient-Reported Outcomes Measurement Information System’s (PROMIS) Physical Function (PF) instrument administered through computerized adaptive testing (CAT) compared to the traditional full-length Disabilities of the Arm, Should and Hand (DASH). METHODS: The PROMIS PF CAT and the DASH were administered to 1,759 patients seeking care for elbow conditions. This study used RASCH Partial Credit Modeling to analyze the instruments with item fit, internal reliability, response category thresholds, dimensionality, local independence, gender differential item functioning, and floor and ceiling effects. RESULTS: The PROMIS PF CAT and DASH had satisfactory item fit for all but one item on both measures. Internal reliabilities were high for both measures. Two items on the DASH and four items on the PF CAT show non-ordered category thresholds. Unidimensionality was adequate and local independence was supported for both instruments. Four items on the PF CAT showed gender bias while 12 items on the DASH were gender biased. Both measures had adequate instrument targeting and satisfactory floor and ceiling effects. CONCLUSION: Both the PROMIS PF CAT and the DASH showed sufficient unidimensionality, good item fit, and good local independence with the exception of high levels of gender item bias, particularly for the DASH. Further scale evaluation should address item bias and item response categories for these instruments. Overall the PROMIS PF CAT is an effective outcome instrument to measure function in patients with elbow disorders requiring significantly fewer questions than the DASH. LEVEL OF EVIDENCE: Basic Science Study, Validation of Outcome Instruments
