Ankylosing Spondylitis Increases Perioperative and Postoperative Complications After Total Hip Arthroplasty.

Background: Ankylosing spondylitis (AS) is a chronic autoimmune spondyloarthropathy that primarily affects the axial spine and hips. Progressive disease leads to pronounced spinal kyphosis, positive sagittal balance, and altered biomechanics. The purpose of this study is to determine the complication profile of patients with AS undergoing total hip arthroplasty (THA).

The Impact of Lumbar Spine Disease and Deformity on Total Hip Arthroplasty Outcomes.

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was assessed.

Laminoplasty versus laminectomy with fusion for the treatment of spondylotic cervical myelopathy: short-term follow-up.

Background Context: Laminoplasty and laminectomy with fusion are two common procedures for the treatment of cervical spondylotic myelopathy. Controversy remains regarding the superior surgical treatment.

Purpose: To compare short-term follow-up of laminoplasty to laminectomy with fusion for the treatment of cervical spondylotic myelopathy.

Cervical Myelopathy Doubles the Rate of Dislocation and Fracture After Total Hip Arthroplasty.

Background: Cervical spondylotic myelopathy (CSM) is a common and underdiagnosed cause of gait dysfunction, rigidity, and falls in the elderly. Given the frequent concurrency of CSM and hip osteoarthritis, this study is designed to evaluate the relative risk of CSM on perioperative and short-term outcomes after total hip arthroplasty (THA).

Methods: The Medicare Standard Analytical Files were searched from 2005 to 2012 to identify all patients undergoing primary THA and the subset of patients with preexisting CSM.

Spondyloarthritis in a patient with unilateral buttock pain and history of Crohn disease.

Background And Purpose: Patients with inflammatory spinal conditions related to spondyloarthritis are rarely seen by primary care practitioners. However, patients with a history of inflammatory bowel disease and chronic low back or buttock pain should be examined carefully for the presence of spondyloarthritis, as proper management may include referral to a rheumatologist and appropriate medical intervention.

Case Description: A 27-year-old woman with a 6-month history of posterior buttock pain was referred for physical therapy with a diagnosis of piriformis syndrome.
