RESUMO
PURPOSE: For preserving the humeral bone stock, some surgeons proposed a stemless humeral prosthetic component. This study reports the functional and radiologic results of the stemless anatomic prosthesis Simpliciti*(Tornier, Wright, Stryker), with the hypothesis that it can achieve a good metaphyseal fixation. METHODS: 28 patients underwent 30 shoulder replacements with the Simpliciti* humeral prosthesis followed for an average of three years (2 months to 8 years). The clinical outcome used the Constant-Murley score and the Bankes resistance and force evaluation. The radiologic assessment looked after radiolucent lines, signs of implant migration, osteolysis or loosening. RESULTS: The Constant score improved from 19.03 preoperatively to 54.03 points post operatively. Radiographic analysis showed one early component loosening, and at the longer follow-up, one radiolucent line. All the other implants appeared well fixed. CONCLUSION: This study verified the quality of the metaphyseal fixation of this stemless implant, with achieving a significant functional improvement. LEVEL OF EVIDENCE: Level IV, Case Series, Treatment Study.
RESUMO
OBJECTIVES: In France, hardware infections occur in 1% of patients following orthopedic surgery. The study aimed to evaluate the quality of life (QoL) and adherence to antibiotic therapy of patients with an orthopedic hardware infection in the postoperative period. PATIENTS AND METHODS: A prospective observational study was conducted at Rouen University Hospital from May 2022 to May 2023. QoL was evaluated using the Short Form Health Survey (SF-36) and therapeutic adherence using the Girerd questionnaire. These forms were filled out by patients during routine follow-up visits at 6- and 12-week follow-up. A cohort of patients with a non-hardware infection was constituted to compare cases and controls. They were paired according to age, sex, and site of index surgery. RESULTS: Seventy-nine patients were enrolled as cases and 158 patients as controls. At six weeks and at 12 weeks, significant decreases were observed in 8/8 and 4/8 sub scores of SF-36, respectively (p < 0.05). Among patients discharged to their homes, at 12 weeks, 30.4 % of patients reported high therapeutic adherence compared to 66.7 % of patients discharged to postoperative care. CONCLUSION: Patients treated for postoperative hardware infections following orthopedic surgery reported a significant decrease in QoL and lower therapeutic adherence, particularly when discharged to their homes.
