Postoperative discal pseudocyst and its similarities to discal cyst: A case report.

Background: Postoperative discal pseudocyst (PDP) is a rare condition that presents after surgery for lumbar disc herniation. Due to the lack of information, the diagnosis and treatment of PDP remain controversial. Herein, we report a PDP case that occurred following percutaneous endoscopic lumbar discectomy and received conservative treatment.

Long-term outcomes following en bloc resection for sacral tumor: a retrospective analysis of 93 cases.

Sacral tumors are rare. Appropriate surgical resection is crucial to treat the disease while minimizing disease recurrence. We present the results of 93 patients with sacral tumors to analyze the long-term functional and oncological results of patients undergoing en bloc resection.

Green fluorescent protein as marker in chondrocytes overexpressing human insulin-like growth factor-1 for repair of articular cartilage defects in rabbits.

Objective: To label the primary articular chondrocytes overexpressing human insulin-like growth factor (hIGF 1) with green fluorescent protein (GFP) for repair of articular cartilage defects in rabbits.

Methods: GFP cDNA was inserted into pcDNA3.1 hIGF 1 to label the expression vector.

Biomechanical study on pullout strength of thoracic extrapedicular screw fixation.

Objective: To identify the biomechanical feasibility of the thoracic extrapedicular approach to the placement of screws.

Methods: Five fresh adult cadaveric thoracic spine from T1 to T8 were harvested. The screw was inserted either by pedicular approach or extrapedicular approach.
