In this study, we established OLIF finite element models with various fixation options in normal and osteoporosis spines, and found that OLIF with BPSR fixation had the best biomechanical properties.

This study is to understand overall development trend of UBE. The number of publications showed an upward trend with a stable rise in recent years. Spondylolisthesis and endoscopic decompression are the research hotspots.

Circ-IQGAP1 promotes IL-1β-induced chondrocyte apoptosis, inflammation, and extracellular matrix degradation by miR-671-5p/TCF4 axis in osteoarthritis.

Osteotomy around the knee (OAK), one of the clinical treatments for knee osteoarthritis (OA), is based on the notion of “knee preservation” and primarily applies to relatively young and high-demand patients. The principle of OAK is to correct the mechanical axis in the lower limbs. According to the types of deformity, the techniques can be divided into anti-varus deformity and anti-valgus deformity osteotomy. By choosing the surgical section of the lower limbs, anti-varus deformity and anti-valgus deformity osteotomy can be further divided into high tibial osteotomy (HTO), proximal fibular osteotomy (PFO), and distal femur osteotomy (DFO). Osteotomy is easy to conduct, low-risk, almost all cases have rapid recovery after surgery, and it has been chosen as an alternative surgical treatment.

To compare early clinical effects of the femoral neck system (FNS) and three cannulated screws for the treatment of patients with unstable femoral neck fractures. We designed a retrospective analysis with pair matching. This study found that compared with cannulated screws, FNS is a suitable option for the treatment of Pauwels type-3 femoral neck fractures. This approach is characterized by its accurate efficacy, simple procedure, reduced trauma, faster recovery, and fewer complications, though it is more expensive. FNS's excellent biomechanical performance and clinical efficacy make it a new choice for the treatment of unstable femoral neck fractures.

Neither PETD nor PEID is a good option for two-level LDH. These approaches are associated with longer surgical time, massive radiation exposure, or unexpected complications. This retrospective study showed that PELD via the transforaminal approach combined with the interlaminar approach under epidural anesthesia can treat L4/5 and L5/S1 two-level disc herniation safely and effectively.

We described an advanced percutaneous endoscopic lumbar foraminotomy by using a specially designed endoscopic trephine. The hard bony decompression was performed directly under endoscopic observation. It combined the efficiency of trephine and the safety of the instruments guided by the endoscope. A safe and effective full-range decompression of the exiting nerve root was achieved by this technique.

TiRobot-assisted percutaneous cannulated screw fixation of femoral neck fractures is accurate and minimally invasive, and helps in reducing late complications, particularly necrosis of the femoral head and nonunion of fracture.

The clinical treatment of IDD includes conservative therapy and surgical therapy. Currently, treatments based on MSCs and ncRNAs are regarded as potential targets. Some ncRNAs verified by clinical trials can be used in gene therapy, and drugs targeting those ncRNAs can also be designed to treat IDD.

The six steps of percutaneous S2 IS screws with TiRobot system. (A) Install patient's tracker; (B) Digital image acquisition and registration; (C) Planning the screw position on the workstation; (D) The mechanical arm moves to the inserted position automatically; (E) Insert the guide wire; (F) Confirm the position of screw.

The study aimed to compare the clinical outcomes of anterior controllable antedisplacement fusion (ACAF), a new surgical technique, with laminoplasty for the treatment of multilevel severe cervical OPLL based on a 2-year follow-up. By achieving anterior direct decompression and better curvature of the spinal cord, satisfactory neurologic outcomes, and low complication rate. ACAF is considered superior to laminoplasty for the treatment of multilevel severe OPLL.

Heterogeneity in assessing the paraspinal muscle fat infiltration exists in imaging modalities, measurement protocols (including measured level and slices, region of interest definition, and fat detection methods), and imaging parameters (semiquantitative and quantitative parameters).

Compared to the open surgery group, the robot-assisted MIS-TLIF group had achieved a better clinical result of significantly more precise pedicle screw placement, less intraoperative blood loss, less postoperative drainage, shorter hospitalization, shorter time to independent ambulation, lower VAS at 3 days post-operation, and less paraspinal muscle atrophy.

Endo-ULBD for LSS has the advantages of less trauma, a shortened operation time and rapid recovery and is an effective alternative for the treatment of lumbar spinal stenosis. Strict surgical indications, reasonable surgical plans and experienced surgeons are important factors to ensure safety and satisfactory efficacy.
