Abstract
Proximal junctional kyphosis (PJK) is a common post-operative phenomenon among patients with adult spinal deformity. In a subset of cases, PJK can progress to proximal junctional failure (PJF) which is PJK with structural failure and usually requires revision surgery. Many patient and surgical risk factors for PJK have been identified in an attempt to predict and prevent the development of PJF. In this paper, we summarize the existing literature regarding the risk factors for and treatment of PJK and PJF. We further provide evidence guided treatment recommendations for surgeons managing spinal deformity patients.
期刊介绍：
Seminars in Spine Surgery is a continuing source of current, clinical information for practicing surgeons. Under the direction of a specially selected guest editor, each issue addresses a single topic in the management and care of patients. Topics covered in each issue include basic anatomy, pathophysiology, clinical presentation, management options and follow-up of the condition under consideration. The journal also features "Spinescope," a special section providing summaries of articles from other journals that are of relevance to the understanding of ongoing research related to the treatment of spinal disorders.
