| Popis: | STUDY DESIGN A retrospective cohort study. OBJECTIVES The aim of this study was to evaluate radiographic and patient-reported outcomes at minimum 2 years after revision surgery for proximal junctional kyphosis (PJK), correlating these results with PJK etiology. SUMMARY OF BACKGROUND DATA There are no studies detailing the results of revision surgery for PJK following posterior segmental instrumentation. METHODS Thirty-two consecutive patients treated with revision surgery after PJK above posterior fusions (25 women/7 men, average age at surgery 60.6 yrs) were reviewed for radiographic and patient-reported outcomes (mean follow-up, 4.5 yrs; range, 2-10 yrs). Patients were subdivided into fracture (F) and nonfracture (NF) groups on the basis of PJK etiology. RESULTS Radiographic severity of PJK improved significantly with revision surgery and was maintained at ultimate follow-up (P |
