Use of Nanocrystalline Hydroxyapatite With Autologous BMA and Local Bone in the Lumbar Spine: A Retrospective CT Analysis of Posterolateral Fusion Results.
A retrospective, multicenter, medical record review and independent analysis of computed tomographic scans was performed in 46 patients to determine radiographic arthrodesis rates after 1-segment, 2-segment, or 3-segment instrumented posterolateral fusions (PLF) using autograft, bone marrow aspirate (BMA), and a nanocrystalline hydroxyapatite bone void filler (nHA). ⋯ The arthrodesis rates after instrumented lumbar fusion using local autograft mixed with BMA and the nHA is equivalent to the rates reported for iliac crest autograft in these indications, including stringent indications, such as 3-segment procedures. By approximately 12 months postoperatively, there was no significant difference in the rates of bridging bone between the 1-segment, 2-segment, and 3-segment procedures.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivitives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

Comparative StudyRadiation exposure for fluoroscopy-guided lumbosacral epidural steroid injections: comparison of the transforaminal and caudal approaches.
A retrospective investigation. ⋯ The longer the fluoroscopy time, the greater the KAP in both transforaminal and caudal ESIs. The fluoroscopy time for transforaminal ESI was longer than that for caudal ESI. However, KAP of transforaminal ESI was less than that of the caudal ESI, after being corrected for the length of fluoroscopy time.

Anterior column realignment (ACR) for focal kyphotic spinal deformity using a lateral transpsoas approach and ALL release.
Retrospective case series. ⋯ Compared with posterior-based techniques, our preliminary results of ACR showed similar correction capacity and similar rate of morbidities for the treatment of focal kyphotic spinal deformity. Careful case selection, attention to the details of the technique, and enough experience are prudent elements for a desirable outcome.

Clinical TrialInfluence of the posterior lumbar interbody fusion on the sagittal spino-pelvic parameters in isthmic L5-S1 spondylolisthesis.
Prospective study of the sagittal spino-pelvic parameters and deformity parameters in low-grade isthmic spondylolisthesis preoperation and postoperation. ⋯ The improvement of PT may play an important role in the reconstruction of the sagittal alignment and therapeutic outcome. The restoration of the slip degree and height of the intervertebral disk would increase the LL with a wedged cage. To get a better LL, the size and geometry of the cage was recommended to be evaluated before surgical treatment.

Comparative StudyA comparison of the somatometric measurements of adolescent males with and without idiopathic scoliosis.
Prospective study comparing the somatometric measurements of young males with normal spinal curves and with adolescent idiopathic scoliosis (AIS) with respect to the severity of AIS. ⋯ In Korean male AIS patients, significantly different somatometric results were observed: namely, a greater corrected height and a lower body weight and BMIs corrected or uncorrected for height. Furthermore, body weight was significantly lower in the severe group than in the moderate group. This study shows that abnormal growth is observed in male AIS patients and that body weight is closely correlated with AIS severity.
