Mild thermal stimulation plays an active role in bone tissue repair and regeneration. In this work, a bioactive polydopamine/TiC/poly(vinylidene fluoride trifluoroethylene) (PDA/TiC/P(VDF-TrFE)) nanocomposite coating with excellent near-infrared light (NIR)-triggered photothermal effect was designed to improve the osteogenic ability of implants. By incorporating dopamine (DA)-modified TiC nanosheets into the P(VDF-TrFE) matrix and combining them with alkali initiated in situ polymerization, the resulting PDA/TiC/P(VDF-TrFE) nanocomposite coating gained high adhesion strength on Ti substrate, excellent tribological and corrosion resistance properties, which was quite important for clinical application of implant coatings.

However, the indications and clinical outcomes of SRS-Schwab Grade 6 osteotomy in patients with SCAK have not been investigated in depth.
Objective: To investigate the middle-term radiographic and clinical outcomes, and to evaluate the safety of this high technique-demanding procedure.
BACKGROUND This retrospective clinical study aimed to compare the efficacy of preoperative halo-gravity traction with postoperative halo-femoral traction after posterior spinal release in corrective surgery for patients with severe kyphoscoliosis. MATERIAL AND METHODS A retrospective clinical study included patients who underwent elective corrective surgery for severe kyphoscoliosis (N=60) between 2013 and 2015. Two patient groups were compared, the postoperative halo-femoral traction after posterior spinal release (R-HF) group (N=30) and the preoperative halo-gravity traction (HGT) group (N=30).

Patients And Methods: This study included neurologically asymptomatic CMS patients undergoing posterior correction surgery between January 2010 and January 2016. IS patients were involved as control group and a subgroup of age- and height-matched IS patients were selected.
Introduction: To compare radiological and clinical outcomes between partial and radical hemivertebra (HV) resection in congenital scoliosis (CS) patients with single nonincarcerated HV.
Methods: CS patients with single HV undergoing partial HV resection from February 2011 to May 2016 were retrospectively reviewed and included in the P group; those undergoing radical HV resection were included in the R group. Patients in R group were age-, sex-, curve magnitude-, and apex location-matched with those in P group.
