BACKGROUND: Most patients suffering from the recurrence of microendoscopic discectomy (MED) need to receive revision surgery. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and percutaneous endoscopic lumbar discectomy (PELD) are common operative methods for MED recurrence, whereas no study has been made to compare the clinical outcomes of these two surgical methods as revision surgery for MED recurrence. METHODS: 105 patients who underwent either MIS-TLIF (58 cases) or PELD (47 cases) for revision of MED recurrence were included in this study...

«Minimally invasive» techniques have been recently been developed in order to achieve good clinical results with a low incidence of complications. The extralateral interbody fusion or direct transpsoas is a minimally invasive anterior arthrodesis. A total of 97 patients with 138 segments received surgery between May 2012 and May 2015. The follow-up was from 12-44 months. The mean age was 68 years (41-86). The most common cause of intervention was the adjacent segment (30%), deformity (22%), and lumbar disc disease (21%)...

BACKGROUND: About one third of lumbar synovial cysts are associated with degenerative spondylolisthesis. Segmental instability is thought to contribute to the pathogenesis and recurrence of synovial cysts and lumbar fusion has been advocated as a treatment of choice in the presence of spondylolisthesis. In patients with spondylolisthesis, minimally invasive resection of lumbar synovial cysts, without fusion, could minimize surgically induced segmental instability while providing good pain relief...

BACKGROUND: Multiple studies have demonstrated that a significant amount of variability exists in various demineralized bone matrix (DBM) formulations, which casts doubts on its reliability in consistently promoting fusion. Bone marrow aspirate (BMA) is a cellular based graft that contains mesenchymal stem cells (MSCs) and growth factors can confer osteogenic and osteoinductive potential to DBM. The goal of this study was to describe the outcome of DBM enriched with concentrated BMA in patients undergoing combined lumbar interbody and posterolateral fusion...

OBJECTIVE: Lumbar fusion is a procedure broadly performed for degenerative diseases of spines, but it is not without significant morbidities. Surgical Apgar Score (SAS), based on intraoperative blood loss, blood pressure, and heart rate, was developed for prognostic prediction in general and vascular operations. We aimed to examine whether the application of SAS in patients undergoing fusion procedures for degeneration of lumbar spines predicts in-hospital major complications. METHODS: One hundred and ninety-nine patients that underwent lumbar fusion operation for spine degeneration were enrolled in this retrospective study...

OBJECTIVE: To assess the association between Hounsfield units (HU) measurement and cage subsidence after lumbar interbody fusion. BACKGROUND: Transforaminal lumbar interbody fusion (TLIF) with unilateral fixation becomes a popular treatment modality for lumbar degenerative disease. Cage subsidence is a potentially devastating complication after lumbar interbody fusion with unilateral fixation. Recently, a new technique for assessing bone mineral density using HU values from computed tomography has been proposed...

BACKGROUND: Bone morphogenetic protein-2 (BMP-2) is a pleiotropic, secreted molecule with diverse effects. The potent ability of BMP-2 to stimulate bone growth prompted its widespread clinical use for arthrodesis (spine fusion). However, elevated post-operative pain in patients treated with BMP-2 has been increasingly reported. Determining whether BMP-2 induces pain directly or whether it induces neuroinflammation, which could lower the threshold for pain, is important for developing therapeutic interventions...

STUDY DESIGN: Prospective, multi-center OBJECTIVE.: To determine if stiffness significantly affects function or satisfaction after pan-lumbar arthrodesis. SUMMARY OF BACKGROUND DATA: The Lumbar Stiffness Disability Index (LSDI) is a validated measure of the effect of lumbar stiffness on functional activities. Data suggests that patients undergoing fusion of the entire lumbar spine are at greatest risk of functional limitations from stiffness. METHODS: The LSDI, Short Form 36 (SF-36), Scoliosis Research Society-22 (SRS-22), and Oswestry Disability Index (ODI) were administered pre-operatively and at 2-year minimum follow-up to 103 spinal deformity patients from 11 centers...

Direct Lumbar Interbody Fusion (DLIF) and eXtreme Lateral Interbody Fusion (XLIF) are the most common surgical platforms available for performing transpsoas spinal fusion but no study has been carried out to compare them. We evaluated 21 DLIF and 22 XLIF cage positions by measuring the distance between the posterior vertebral border and the centre of the cage normalised to the midsagittal length of the inferior end plate. We found that DLIF cages were significantly more anteriorly located than XLIF (0.65 vs 0...

Intervertebral instability risks following L5-S1 transforaminal lumbar interbody fusion (TLIF) and causes of bony bridge formation on computed tomography (CT) remain largely unknown. We evaluated the temporal changes on plain radiographs and reconstructed CT images from 178 patients who had undergone single-level L5-S1 TLIF between February 2011 and February 2015. We statistically analyzed temporal changes the L5-S1 angle on radiographs and intervertebral stability (IVS) at the last observation. Bony bridge formation between the L5-S1 vertebral bodies and the titanium cage subsidence were analyzed by using reconstructed CT...

BACKGROUND: National databases are increasingly being used for research in spine surgery; however, one limitation of such databases that has received sparse mention is the frequency of missing data. Studies using these databases often do not emphasize the percentage of missing data for each variable used and do not specify how patients with missing data are incorporated into analyses. This study uses the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to examine whether different treatments of missing data can influence the results of spine studies...

RATIONALE: Lumbar osteoid osteoma has a low incidence, which could easily lead to scoliosis. PATIENT CONCERNS: Scoliosis secondary to lumbar osteoid osteoma could be easily misdiagnosed when patients do not complain of obvious symptoms. DIAGNOSES: We reported a case of a 9-year-old boy with back deformity that was firstly diagnosed with scoliosis at the local hospital. After prescribed with orthosis, the patient experienced aggravating pain that could not be relieved with painkillers...
