BACKGROUND CONTEXT The evidence surrounding the topic of adjacent segment degeneration and disease has increased dramatically with an abundant amount of literature discussing the incidence of and techniques to avoid it. However, this evidence is often confusing to discern because of various definitions of both adjacent segment degeneration and disease. (More)
The need for posterolateral fusion (PLF) in addition to interbody fusion during minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) has yet to be established. Omitting a PLF significantly reduces overall surface area available for achieving a solid arthrodesis, however it decreases the soft tissue dissection and costs of additional bone(More)
BACKGROUND Open calcaneus fractures can be limb threatening and almost universally result in some measure of long-term disability. A major goal of initial management in patients with these injuries is setting appropriate expectations and discussing the likelihood of limb salvage, yet there are few tools that assist in predicting the outcome of this(More)
STUDY DESIGN Fresh-frozen human cadaveric biomechanical study. OBJECTIVE To evaluate the biomechanical consequence of pedicle screw reinsertion in the thoracic spine. SUMMARY OF BACKGROUND DATA During pedicle screw instrumentation, abnormal appearance on fluoroscopic imaging or low current reading with intraoperatively evoked electromyographic(More)
BACKGROUND CONTEXT There are no guidelines for when surgeons should allow patients to return to sports and athletic activities after spinal fusion for adolescent idiopathic scoliosis (AIS). Current recommendations are based on anecdotal reports and a survey performed more than a decade ago in the era of first/second-generation posterior implants. PURPOSE(More)
STUDY DESIGN  Systematic review.Clinical questions: (1) What evidence is available from studies of cervical total disc arthroplasty (C-ADR) failure and retrieval regarding durability, wear, and reasons for failure of C-ADR? (2) What evidence is available from experimental models regarding the durability of C-ADR beyond 5 years? METHODS  We searched(More)
BACKGROUND The Iraq and Afghanistan Wars have presented military reconstructive surgeons with a high volume of challenging extremity injuries. In recent years, a number of upper and lower extremity injuries requiring multiple tissue transfers for multiple limb salvages in the same casualty have been encountered. Our group will discuss the microsurgical(More)
BACKGROUND A previous biomechanical study using adult thoracic vertebrae (both normal and osteoporotic bone density) demonstrated the deleterious effect of the pedicle screw hubbing technique. Pedicle screw "hubbing" involves seating and engaging the ventral aspect of the screw head onto the dorsal lamina cortex. This technique is postulated to provide a(More)
BACKGROUND CONTEXT The use of a rod reduction device can have deleterious consequences on pedicle screw pullout strength (POS) in the thoracic spine. However, posterior-only osteotomies in the thoracic spine are often performed to improve flexibility of the spine and offset forces of deformity correction maneuvers. PURPOSE To investigate the effect on(More)
STUDY DESIGN A human cadaveric biomechanical analysis. OBJECTIVE The purpose of this study was to evaluate the bone density/trabecular width of the thoracic pedicle and correlate that with its resistance against compressive loading used during correction maneuvers in the thoracic spine (i.e., cantilever bending). SUMMARY OF BACKGROUND DATA As surgeons(More)
