BACKGROUND Posterior decompression, instrumentation, and posterolateral fusion are surgical procedures for the treatment of degenerative lumbar diseases. Solid fusion usually causes adjacent problems. This study investigated the clinical outcome and radiographic fate of the L5-S1 segment in patients who underwent posterior instrumented surgery for degenerative lumbar diseases. METHODS From Ja...

This study is a retrospective review of 122 patients who underwent single-level lumbar spine fusion. The objectives were to directly compare perioperative morbidity and early results of single-level anterior interbody posterolateral intertransverse process lumbar spine fusion and to provide objective findings that may be useful in selecting surgical method. Lumbar spinal fusion is a well-recogn...

Study Design Retrospective comparative cohort. Objective Pseudarthrosis following fusion for degenerative lumbar spine pathologies remains a substantial problem. Current data shows that patients who develop a pseudarthrosis have suboptimal outcomes. This study evaluates if treatment of pseudarthrosis can be affected by surgical approach. Methods Medical records of 63 female and 65 male patients...

Lumbar degenerative disease (LDD) refers to the normal strain of body involving lumbar bone, ligament, intervertebral disc, thereby protruding slippage, spinal stenosis and other lesions. fusion surgery has been proved be an effective strategy for treatment LDD. At present, a variety methods such as anterior posterior have reported. This article aims review discuss reported strategies LDD relat...

BACKGROUND The vast majority of studies emphasize the greater morbidity/mortality for elective spine surgery in morbidly obese patients. METHODS This review focuses on the increased morbidity/mortality of performing elective spinal operations in morbidly obese patients. There are two definitions of morbid obesity; a body mass index (BMI) of equal to or greater than 35 plus two major comorbid ...

BACKGROUND The current study presents a technique (navigated posterior lumbar fusion) which takes a 5-cm incision to accomplish a 2-level posterior lumbar fusion (PLF) and compared its efficacy and efficiency with those of conventional PLF. METHODS Forty patients who were indicated for 2-level lumbar fusion were included and randomized to either navigated PLF group or conventional PLF group. ...

STUDY DESIGN Review article, review of literature. OBJECTIVE To review the bone graft options that exist for posterolateral and posterior interbody lumbar fusion. SUMMARY OF BACKGROUND DATA As the number of lumbar fusion surgeries has increased over the last decade, alternative methods of grafting have been developed. Iliac crest autograft bone has traditionally been used for lumbar fusion....

BACKGROUND Lumbar spine fusion rates can vary according to the surgical technique. Although many studies on spinal fusion have been conducted and reported, the heterogeneity of the study designs and data handling make it difficult to identify which approach yields the highest fusion rate. This paper reviews studies that compared the lumbosacral fusion rates achieved with different surgical tech...
