Sacroiliac Pain: Structural Causes of Pain Referring to the SI Joint Region.

Background: The currently reported incidence of primary sacroiliac joint (SIj) pathology ranges from 15% to 30%. The differential diagnosis of SIj region pain includes pain generated from the lumbar spine, the SIj, and the hip joint. The origins of SIj dysfunctions are controversial and pain generation from this joint has been questioned.

Navigation accuracy comparing non-covered frame and use of plastic sterile drapes to cover the reference frame in 3D acquisition.

Background: Advancements in surgical navigation technology coupled with 3-dimensional (3D) radiographic data have significantly enhanced the accuracy and efficiency of spinal fusion implant placement. Increased usage of such technology has led to rising concerns regarding maintenance of the sterile field, as makeshift drape systems are fraught with breaches thus presenting increased risk of surgical site infections (SSIs). A clinical need exists for a sterile draping solution with these techniques.

Failed less invasive lumbar spine surgery as a predictor of subsequent fusion outcomes.

Purpose: It is not uncommon for patients to undergo less invasive spine surgery (LISS) prior to succumbing to lumbar fusion; however, the effect of failed LISS on subsequent fusion outcomes is relatively unknown. The aim of this study was to test the hypothesis that patients who suffered failed LISS would afford inferior subsequent fusion outcomes when compared to patients who did not have prior LISS.

Methods: After IRB approval, registry from a spine surgeon was queried for consecutive patients who underwent fusion for intractable low back pain.

Intraoperative monitoring may prevent neurologic injury in non-myelopathic patients undergoing ACDF.

The efficacy of spinal cord monitoring for patients undergoing anterior cervical discectomy and fusion (ACDF) as indicated for radiculopathy without myelopathy is debated in the literature. The reported rate of complications is low for this procedure. Previous studies have shown both improvements in outcome as well as no change in monitored vs.

Recombinant human bone morphogenetic protein-2-augmented transforaminal lumbar interbody fusion for the treatment of chronic low back pain secondary to the homogeneous diagnosis of discogenic pain syndrome: two-year outcomes.

Study Design: A retrospective observational study.

Objective: To assess clinical outcomes, perioperative complications, revision surgery rates, and recombinant human bone morphogenetic protein-2 (BMP-2)-related osteolysis, heterotopic bone, and unexplained postoperative radiculitis (BMPP) in a group of patients treated with BMP-2-augmented transforaminal lumbar interbody fusion (bTLIF) for the homogeneous diagnosis of discogenic pain syndrome (DPS) and to put forth the algorithm used to make the diagnosis.

Summary Of Background Data: There is a paucity of literature describing outcomes of TLIF for the homogeneous diagnosis of DPS, an old but controversial member of the lumbar degenerative disease family.
