Worker's Compensation Terminology.

Injuries to the spine comprise a high percentage of workplace injuries. Spine surgeons' evaluation of injured workers requires attention to facts specific to worker's compensation claims including whether the injury occurred in the scope of employment, whether a work incident was causally related to the injury, and whether the injury contributed to a significant degree to the patient's overall medical condition. An injured worker's compensation is subject to state-specific guidelines and is largely dependent on the degree of disability and whether the disability is temporary or permanent.

Anterior lumbar instrumentation improves correction of severe lumbar Lenke C curves in double major idiopathic scoliosis.

Fifteen skeletally immature patients with double major adolescent idiopathic scoliosis with large lumbar curves and notable L4 and L5 coronal plane obliquity were retrospectively studied. Seven patients who underwent anterior release and fusion of the lumbar curve with segmental anterior instrumentation and subsequent posterior instrumentation ending at L3 were compared with eight patients treated with anterior release and fusion without anterior instrumentation followed by posterior instrumentation to L3 or L4. At 4.

Primary total hip arthroplasty with a proximally porous-coated femoral stem.

Background: The use of cementless, proximally porous-coated femoral stems for total hip arthroplasty has increased in popularity. The purpose of the present report was to examine the five to ten-year results associated with the use of a so-called second-generation circumferentially proximally porous-coated titanium-alloy stem.

Methods: Between 1991 and 1994, 123 Harris-Galante Multilock femoral stems were implanted in 101 patients.

Paradoxic cerebral embolism after cemented knee arthroplasty: a report of 2 cases and prophylactic option for subsequent arthroplasty.

Major orthopaedic procedures that involve instrumentation of the medullary canal are well known to produce showers of embolic debris including fat, bone fragments, marrow constituents, and cement. A growing literature has identified paradoxic cerebral embolism as a rare but serious consequence of the passage of these emboli through an intracardiac right-to-left shunt to the cerebral arterial circulation. We report 2 cases of paradoxic cerebral embolism after cemented total knee arthroplasty and propose a novel treatment plan to prevent recurrent stroke during subsequent surgery.
