Clinical observation of C3-type patellar fractures treated by operation methods with or without a turned-over patella.

Objective: To evaluate the clinical efficacy of operation methods with or without a turned-over patella for treatment of C3-type patellar fractures.

Methods: A total of 68 patients with C3-type patellar fractures undergoing open reduction and internal fixation were retrospectively selected and treated with a turned-over patella surgery (turned-over patella group, n = 30) or conventional therapy without turning over the patella (conventional group, n = 38). The intraoperative and postoperative indicators of the two groups were assessed and comparatively analyzed.

Effect of c-erbB2 overexpression on prognosis in osteosarcoma: evidence from eight studies.

C-erbB2 (HER-2/neu) plays an important role in the progression of several types of cancer by increasing tumor growth, migration, invasion, and metastasis and is associated with poor disease prognosis. Numerous studies examining the relationship between c-erbB2 expression and prognostic impact in patients with osteosarcoma have yielded inconclusive results. We therefore conducted a meta-analysis to provide a comprehensive evaluation of the prognostic role of c-erbB2 expression on 5-year survival, which compared the positive and negative expression of c-erbB2 in patients of the available studies.

Pedicle screw fixation with translaminar facet joint screws for the treatment of thoracolumbar fracture.

Objective: To evaluate the efficacy of Cotrel-Dubeusset (CD) instrumentation combined with translaminar facet joint screw (TLS) in the treatment of thoracolumbar fracture.

Methods: A total of six L(2)-L(4) spines were used to establish unstable fracture model with three-dimensional range of motion (ROM) of the spines measured. Fixation with CD and fixation with CD combined with translaminar facet joint screw were achieved to compare their stability.
