The purpose of this review is the current understanding of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) following adult spinal deformity (ASD) surgery. We carried out a systematic search of PubMed for literatures published up to September 2017 with "proximal junctional kyphosis," "proximal junctional failure," and "adult spinal deformity" as search terms. A total of ...

OBJECTIVE To evaluate the results of the surgical treatment of the spinal Kyphosis using the Ponte's technique (multiple posterior osteotomies). METHODS Ten patients (8 with Scheuermann's kyphosis and 2 with kyphosis after laminectomy) submitted to surgical correction of kyphotic deformity greater than 70° were retrospectively assessed. The age at the surgical time ranged from 12 to 20 years ...

BACKGROUND Despite its importance in affecting adult pain, and disability, there is a lack of universal criteria for the diagnosis and evaluation of thoraco-lumbar Junctional Kyphosis (JK) and a gold standard measurement and diagnostic system does not exist. This study aims to verify the sensibility and specificity of clinical, and Formetric surface topography (FST) data in identifying Junction...

STUDY DESIGN Retrospective study. OBJECTIVE To compare 2 methods of selecting the lowest instrumented vertebra (LIV) on the rates of revision surgery for distal junctional kyphosis (DJK) following treatment for Scheuermann's kyphosis (SK). METHODS A retrospective review of patients who have undergone surgical treatment for SK was performed. Forty-four patients were divided into 2 groups bas...

OBJECTIVE To analyze the efficacy of the method for selecting the distal level of fusion in treatment of thoracic hyperkyphosis in patients with Scheuermann's disease. BACKGROUND The fusion area needs to include all the kyphotic deformity in Scheuermann patients; however, precise levels of the distal fixation have not been determined yet. STUDY DESIGN Retrospective cohort review. MATERIAL...

STUDY DESIGN Cohort study. OBJECTIVE To analyze long-term clinical and radiological outcomes of surgically treated Scheuermann patients. SUMMARY OF BACKGROUND DATA Long-term clinical and radiological outcomes of surgery for Scheuermann kyphosis are unknown. A single-center cohort of 33 consecutive, surgically treated (between 1991 and 1998) Scheuermann patients was studied. METHODS Clinic...

STUDY DESIGN Multicenter, retrospective, consecutive case series. OBJECTIVE This study aims to identify demographic and radiographical characteristics that influence the decision to perform revision surgery among patients with proximal junctional failure (PJF). SUMMARY OF BACKGROUND DATA Revision rates after PJF remain relatively high, yet the decision criteria for performing revision surgi...

The authors have performed a retrospective study of 20 patients who underwent surgical treatment for kyphosis secondary to trauma (10 patients) or Scheuermann's disease (10 patients) between 1992 and 2000. The mean follow-up was 60 months (range, 32-90) and 59.5 months (range, 24-109) respectively. Radiological evaluation of Scheuermann kyphosis included assessment of thoracic kyphosis angle (T...
