Clinical efficacy of one-hole split endoscopy vs. unilateral biportal endoscopy for the treatment of single-segment lumbar spinal stenosis: a retrospective study with 2-year follow-up.

Background: One-hole split endoscopy (OSE) is a novel endoscopic technique proposed by Chinese scholars in recent years. Currently, data is lacking regarding the long-term efficacy of OSE for treating lumbar spinal stenosis (LSS). This study aimed to compare the long-term efficacy of OSE and unilateral biportal endoscopy (UBE) in LSS treatment.

Contact between leaked cement and adjacent vertebral endplate induces a greater risk of adjacent vertebral fracture with vertebral bone cement augmentation biomechanically.

Background Context: Adjacent vertebral fracture (AVF) is a frequently observed complication after percutaneous vertebroplasty in patients with osteoporotic vertebral compressive fracture (OVCF). Studies have demonstrated that intervertebral cement leakage (ICL) can increase the incidence of AVF, but others have reached opposite conclusions. The stress concentration initially increases the risk of AVF, and dispersive concentrated stress is the main biomechanical function of the intervertebral disc (IVD).

Angiogenesis unveiled: Insights into its role and mechanisms in cartilage injury.

Osteoarthritis (OA) commonly results in compromised mobility and disability, thereby imposing a significant burden on healthcare systems. Cartilage injury is a prevalent pathological manifestation in OA and constitutes a central focus for the development of treatment strategies. Despite the considerable number of studies aimed at delaying this degenerative process, their outcomes remain unvalidated in preclinical settings.

Clinical efficacy of posterior endoscopic cervical modified trench technique in the treatment of cervical spondylotic myelopathy: A retrospective study.

To investigate the clinical efficacy of the posterior endoscopic cervical modified trench technique in the treatment of cervical spondylotic myelopathy (CSM). This retrospective study included 9 patients with single-segment CSM, who were treated with posterior endoscopic cervical modified trench technique. Related clinical data, the visual analog scale, Japanese Orthopedic Association (JOA) ratings, JOA improvement rate, the minimum sagittal diameter of the spinal canal, and surgical complications were recorded.

Efficacy of three-dimensional guide plate technique guided sacral 2 alar iliac screws fixation in patients with degenerative kyphoscoliosis.

Objective: To investigate the efficacy of three-dimensional (3D) guide plate technique guided sacral 2 alar iliac (S2AI) screws fixation in patients with degenerative kyphoscoliosis.

Methods: Eighty-four patients with degenerative kyphoscoliosis who were admitted to our hospital were selected as the subjects. They were divided into control group and observation group by the random number table method, with 42 patients in each group.

[Evaluation and treatment of osteochondral injury of knee joint].

Objective: To investigate evaluation and treatment of osteochondral injury of knee joint and its effectiveness.

Methods: Between January 2010 and January 2016, 17 patients with osteochondral injury of knee joint were admitted. There were 2 males and 15 females, with an average age of 19.
