[Clinical efficacy and technical characteristics of percutaneous endoscopic lumbar discectomy in the treatment of upper lumbar disc herniation].

Objective: To analyze the clinical efficacy and technical characteristics of percutaneous endoscopic lumbar discecomy in the treatment of upper lumbar disc herniation.

Methods: The clinical data of 9 patients with upper lumbar disc herniation underwent percutaneous endoscopic lumbar discecomy from January 2012 to October 2019 were retrospectively analyzed. There were 6 males and 3 females, aged 26 to 79 years, including 2 patients with L disc herniation and 7 patients with L2, 3 disc herniation.

Posterior Lumbar Interbody Fusion with Interspinous Fastener Provides Comparable Clinical Outcome and Fusion Rate to Pedicle Screws.

Objective: To investigate the clinical feasibility and validity of interspinous fastener (ISF) for lumbar degenerative diseases.

Methods: From October 2013 to March 2014, a total of 46 patients suffering from lumbar degenerative diseases underwent posterior lumbar interbody fusion (PLIF) randomly augmented by ISF or pedicle screws. The clinical outcome was primarily measured by Oswestry Disability Index (ODI) score.

Impacts of Tumor Location, Nature and Bone Destruction of Extremity Osteosarcoma on Selection of Limb Salvage Operative Procedure.

Objective: To study the impacts of tumor location, nature and extent of bone destruction on selection of operative protocol for extremity osteosarcoma (OS).

Methods: The medical records of 201 patients with extremity OS treated in our institute from December 1999 to June 2014 were retrospectively reviewed. Ninety eligible patients (56 males and 34 females) of average age 20 ± 11 years (range, 4-40 years) were enrolled.

Triptolide (TPL) improves locomotor function recovery in rats and reduces inflammation after spinal cord injury.

In this study, we studied the effect of triptolide (TPL) on locomotor function in rats with spinal cord injury. A total of 40 rats were studied after dividing them in two major groups, one was experimental group denoted as TPL group while other was control group denoted as PBS group. Each group was subdivided in four subgroups having five rats each (n = 5).

[Clinical efficacies of skipping two-level transpedicular wedge osteotomy for correction of severe kyphosis in ankylosing spondylitis].

Objective: To explore the clinical efficacies of skipping two-level transpedicular wedge osteotomy in the correction of severe kyphotic deformity in ankylosing spondylitis (AS).

Methods: From January 2003 to December 2009, a total of 38 consecutive patients with AS and severe kyphosis (chin-brow vertical angle (CBVA) or global thoraco-lumbar kyphosis angle (TLKA) over 70°) undergoing skipping two-level transpedicular wedge osteotomy at the Department of Orthopedics of Chinese PLA General Hospital were reviewed retrospectively. There were 32 males and 6 females with an average age of 38.

[One-stage total en bloc spondylectomy and reconstruction via a single posterior approach for thoracic vertebral symptomatic hemangioma associated with spinal cord dysfunction].

Objectives: To investigate the surgical results of one-stage total en bloc spondylectomy (TES) and reconstruction via a single posterior approach for thoracic symptomatic vertebral hemangioma associated with spinal cord dysfunction and evaluate its curative effect.

Methods: A total of 9 patients treated with one-stage TES (7 cases) and total vertebrectomy (2 cases) by posterior approach from March 2006 to January 2010 were retrospectively reviewed. The cases included 2 males and 7 females with a median age of 33.

Long-term outcomes of epiphyseal preservation and reconstruction with inactivated bone for distal femoral osteosarcoma of children.

Objectives: To study the long-term outcomes of inactivated bone reimplantation with preservation of the epiphysis in children with distal femoral osteosarcomas.

Methods: Over 10 years, five children (mean age 9.2 years, one boy and four girls) with distal femoral osteosarcomas underwent inactivated bone reimplantation with preservation of the epiphysis following chemotherapy in our hospital.

Long-term outcome of giant cell tumors of bone around the knee treated by en bloc resection of tumor and reconstruction with prosthesis.

Objective: To study the long-term outcomes and complications of giant cell tumors around the knee treated with en bloc resection and reconstruction with prosthesis.

Methods: From January 1991 to March 2005, 19 patients (11 men, 8 women, average age 35.4 years) were treated in our hospital with en bloc resection and reconstruction with domestic prosthesis (15 hinge knee and 4 rotating-hinge knee).
