OBJECTIVE Bilateral symptoms have been reported in 8%-35% of patients with sacroiliac (SI) joint dysfunction. Stabilization of a single SI joint may significantly alter the stresses on the contralateral SI joint. If the contralateral SI joint stresses are significantly increased, degeneration may occur; alternatively, if the stresses are significantly reduced, bilateral stabilization may be unnecessary for patients with bilateral symptoms. The biomechanical effects of 1) unilateral stabilization on the contralateral SI joint and 2) bilateral stabilization on both SI joints are currently unknown...

INTRODUCTION: The use of distal sacral anchorage solely, in long spinal fusions, may lead to substantial complications. Extending the fixation down to the ilium and the addition of anterior column support are both used to facilitate construct stability and improve fusion rates. In the current study, we aimed to determine whether supplementation of long thoracolumbar fixation constructs with stand-alone anterior interbody fusion (ALIF) cage with embedded screws can eliminate the biomechanical need for iliac screws fixation biomechanically...

BACKGROUND: Atraumatic lower limb amputation is a life-changing event for approximately 185,000 persons in the United States each year. A unilateral amputation is associated with rapid changes to the musculoskeletal system including leg and back muscle atrophy, strength loss, gait asymmetries, differential mechanical joint loading and leg length discrepancies. Even with high-quality medical care and prostheses, amputees still develop secondary musculoskeletal conditions such as chronic low back pain (LBP)...

Low back pain (LBP) can be detrimental to the career of a circus arts performer, yet there is minimal population-specific literature to guide care. Moreover, reluctance to discontinue training and the need to resume end-range lumbar motion can impede the success of conservative care. The purpose of this case report is to describe the use of a patient-specific outcome measure and a movement classification system to structure a home exercise program (HEP) for an adolescent training to be a circus performer. The patient was a 16-year-old female with a 10-month history of LBP...

INTRODUCTION: Spondylopelvic dissociation is an uncommon and complex injury that results from high-energy trauma with axial overloading through the sacrum. Due to the life-threatening nature of these injuries, standard Advanced Trauma Life Support® (ATLS) protocol must be used in the trauma setting as part of the initial management of these patients. The key to diagnosis is a good physical exam coupled with high level of suspicion. Radicular neurological deficits commonly are present in spondylopelvic dissociation (L5's roots) and should be documented for future evaluations...

Background/Purpose: Athletes experiencing hip, groin, and low back pain often exhibit similar clinical characteristics. Individuals with hip, groin and low back pain may have the presence of multiple concurrent pathoanatomical diagnoses. Regardless, similar regional characteristics and dysfunction may contribute to the patient's chief complaint, potentially creating a sub-group of individuals that may be defined by lumbopelvic and hip mobility limitations, motor control impairments, and other shared clinical findings...

Background/Purpose: The Selective Functional Movement Assessment (SFMA) is a clinical model used to assist diagnosis and treatment of musculoskeletal disorders by identifying dysfunctions in movement patterns. Based on the premise that addressing movement dysfunction is associated with an improvement in patient outcomes, the validity of the SFMA would be strengthened by observed improvement in self-reported function being associated with change in movement patterns. The purpose of this study was to explore the validity of the SFMA by determining if a correlation exists between a change in self-reported outcome measures and attributes of the assessment...

This case presentation describes a 50-year-old healthy woman who developed left sided hip pain while training for the Boston Marathon. Magnetic Resonance Imaging (MRI) demonstrates a stress fracture of the left iliac body. This injury is unique in that it did not occur in the setting of low bone mineral density and it does not fall into the current published radiographic categorization based on location of injury. This case illustrates an uncommon and atypical bone stress injury in an endurance athlete. It should be considered in the differential diagnosis of runners presenting with hip or lumbopelvic pain...

PURPOSE: U-shaped sacral fractures are extremely rare injuries that usually occur as a result of falls from considerable heights. Almost all treatment methods described to date aim solely at stabilizing the fracture but do not contribute to supporting the reduction of such fractures. Using existing implants the purpose of this study is to present a surgical technique that facilitates both the reduction and the stabilization of these injuries. The presented technique was evaluated in a series of three cases...

INTRODUCTION: Previous investigations have identified compensatory movement strategies (CMS) within the lower extremity or lumbopelvic complex during closed chain exercises may be associated with a loss of ankle dorsiflexion range of motion (ROM). The aim of this study was to investigate the acute effects of ankle mobilisations on proximal joint kinematics during a movement task that demands a high amount of ankle dorsiflexion ROM. METHODS: Eight healthy males (mean (SD) age 25 (4) years) demonstrating side-to-side asymmetry during the weight-bearing lunge test (WBLT) and CMS during the single-leg step-down exercise were accepted for this study...
