Tubular microdiskectomy (tMD) is one of the most commonly used for treating lumbar disk herniation. However, there still patients still complain of persistent postoperative residual low back pain (rLBP) postoperatively. This study attempts to develop a nomogram to predict the risk of rLBP after tMD. ⋯ This nomogram including preoperative LBP VAS score, FO, FJD and MFA can serve a promising prediction model, which will provide a reference for clinicians to predict the rLBP after tMD.

To assess direct costs and risks associated with revision operations for distal junctional kyphosis/failure (DJK) following thoracic posterior spinal instrumented fusions (TPSF) for adolescent idiopathic scoliosis (AIS). ⋯ In this single-center experience, risk factors for development of DJK were greater BMI, lower post-operative thoracic kyphosis, and LIV cranial to SSV. As revision operations for DJK were significantly more costly than index operations, all efforts should be aimed at strategies to prevent DJK in the AIS population.

This study aimed to use MRI histogram analysis to routine MRI sequences to evaluate lumbar disc degeneration (LDD), illustrate the correlation between this novel method and the traditional Pfirrmann classification method, and more importantly, perform comprehensive agreement analysis of MRI histogram analysis in various situations to evaluate its objectivity and stability. ⋯ MRI histogram analysis, used in routine MRI sequences, demonstrated a strong correlation with Pfirrmann classification and good agreements in various scenarios, expanding the range of application and providing an effective, objective and quantitative tool to evaluate LDD.

Prader-Willi syndrome (PWS) represents a difficult challenge for spine surgeons, due to the association of a structural scoliosis, with a prevalence between 15 and 86%. Conservative therapy is a viable option, but surgery is increasingly becoming the treatment of choice. ⋯ Spine surgery represents a convincing option in patients affected by PWS, but the risks of complications are high. Correct patient selection must be the main objective, and multilevel pedicle screw fixation should be the procedure of choice. Traditional growing rod should be prudently evaluated in every single case.

Scoliometry is not always included in the examination protocol of IS patients. The aim of this report is to examine the degree of correlation of Segmental Rib Index (SRI) to scoliometry, in order for SRI to be used as a surrogate of scoliometric angle of trunk rotation (ATR). ⋯ It was suggested that as long as the patients doesn't have scoliometer measurements, the SRI, could be used as a surrogate for scoliometry. It was also found that in thoracic, thoracolumbar and lumbar level, in both genders, changing from the flexed position to the standing position, the mean trunk asymmetry (TA) decreases. Therefore, if these patients had their TA measured using a scoliometer during the Adams test, their body asymmetry would have been greater than that measured using the SRI method on standing LSR. Consequently, it is evident that the significantly correlated SRI used as a surrogate for the scoliometric assessment of TA is reasonably a strong surrogate.
