Purpose In this article, we summarize our work on understanding the influence of cervical
sagittal malalignment on the mechanics of the cervical spine. Methods Biomechanical studies …

Study Design. A biomechanical study using human spine specimens. Objective. To study
postural compensations in lordosis angles that are necessary to maintain horizontal gaze in …

Background. Forward head posture (FHP) may be associated with neck pain and poor
health-related quality of life. Literature describes only qualitative muscle length changes …

Study Design. A biomechanical study using human spine specimens. Objective. The aim of
this study was to assess whether the presence of cervical sagittal imbalance is an …

Study Design. Cadaveric study to accurately measure lumbar neuroforaminal area and
height throughout the flexion-extension range of motion (ROM). Objective. Create a new …

Introduction Anterior cervical discectomy and fusion has been associated with the development
of adjacent segment degeneration (ASD), with clinical incidence of approximately 3% …

Purpose Patients with cervical spondylosis commonly present with neck pain, radiculopathy
or myelopathy. As degenerative changes progress, multiple factors including disc height loss…

Introduction: Suboptimal acetabular component position can result in impingement,
dislocation, and accelerated wear. Intraoperative pelvic motion has led to surgeon error and …

Background The need for posterior longitudinal ligament (PLL) resection during cervical
total disc arthroplasty (TDA) has been debated. The purpose of this laboratory study was to …

Chronic Forward Head Posture is associated with headaches, neck pain, and disability, though
few studies have investigated the effects it has on the suboccipital triangle. The objective …
