To explore the method and curative effect of double bundle reconstruction of posterior cruciate ligament with total internal short tendon technique. ⋯ Arthroscopic double bundle reconstruction of posterior cruciate ligament with short internal tendon is safe and reliable, with less tendon transplantation, more stable fixation, and more bone reserve, which is beneficial for healing and renovation. The short term effect is positive.
-
To introduce the technical key points of lumbar annulus fibrosus suture under full-endoscope and analyze the clinical efficacy of full-endoscopic lumbar discectomy and annulus fibrosus suture. ⋯ Full-endoscopic lumbar discectomy and annulus fibrosus suture are safe and effective techniques for minimally invasive spinal surgery, which can reduce the recurrence rate of lumbar disc herniation after full endoscopic lumbar discectomy.
-
To explore clinical effects of platelet rich plasma (PRP) injection in treating atrophic fracture nonunion. ⋯ The stability of fracture ends of atrophic fracture nonunion after internal fixation is an indication for local PRP injection. PRP treatment for atrophic fractures could completed under local anesthesia, and it has advantages of safe operation and reliable efficacy.
-
To investigate the clinical effect of double-door laminoplasty combined with C2 dome decompression in treatment of cervical spinal stenosis. ⋯ Double-door laminoplasty combined with C2 dome decompression can directly expand the volume of C2-C3 spinal canal, relieve the compression of spinal cord and nerve root, reduce the damage to the posterior cervical ligament complex as much as possible, maintain the stability of cervical spine sequence, reduce the occurrence of axial symptoms, and the operation is relatively simple, without the need of metal internal fixation.
-
To explore the application value of 3D printing technology in preoperative surgery plan and intraoperative auxiliary operation for adult kyphoscoliosis deformity. ⋯ The 3D print model can visually and clearly show the vertebral morphology and structure of adult kyphoscolisis and its spatial relationship with the adjacent vertebrae, blood vessels, and nerves, which provides a good and intuitive stereoscopic anatomical structure observation for the individualization of the surgical plan. Pre-simulation of operations to determine the internal fixation, fusion segment and osteotomy orthopedic way, may to provide a reference for actual clinical surgery, and can improve the accuracy and safety of surgery.
