Twenty-eight patients with osteoporotic vertebral compression fractures (OVCF) were treated with single-balloon bipedicular kyphoplasty (Group A), and 40 patients were treated with double-balloon bipedicular kyphoplasty (Group B). Visual Analogue Scale (VAS) score, vertebral height, and kyphotic angle (KA) were evaluated pre-operatively, post-operatively (3(More)
BACKGROUND Numerous studies examining the relationship between CD44 expression and prognostic impact in patients with osteosarcoma have yielded inconclusive results. The aim of this meta-analysis was carried out to investigate the relationship between CD44 expression and the survival in patients with osteosarcoma. METHODS We therefore conducted a(More)
This paper presents 14 cases of primary reconstruction of radial-part hand defect by combined free-tissue transfer. The thumb was reconstructed by wraparound flap or second-toe transfer, while a lateral upper-arm flap or anterolateral thigh flap was transferred to cover the soft-tissue defect of the radial part of the hand. The arteries of the toe and flap(More)
Balloon kyphoplasty has been shown to be safe in treatment of vertebral compression fractures refractory to conservative management. However, few reports have focused on lateral wedging of cemented vertebra after kyphoplasty. A 72-year-old woman with a T12 osteoporotic compression fracture underwent kyphoplasty using polymethylmethacrylate (PMMA) via a(More)
OBJECTIVE To compare the effective of short-segment pedicle instrumentation with bone grafting and pedicle screw implanting in injured vertebra and cross segment pedicle instrumentation with bone grafting in injured vertebra for treating thoracolumbar fractures. METHODS A prospective randomized controlled study was performed in 40 patients with(More)
OBJECTIVE To summarize the progress of Masquelet technique to repair bone defect. METHODS The recent literature concerning the application of Masquelet technique to repair bone defect was extensively reviewed and summarized. RESULTS Masquelet technique involves a two-step procedure. First, bone cement is used to fill the bone defect after a thorough(More)
OBJECTIVE To evaluate the surgical technique and effectiveness of arthroscopic treatment for lateral discoid meniscus injury. METHODS Between January 2010 and May 2011, 38 patients (42 knees) with lateral discoid meniscus injuries underwent arthroscopic treatment. There were 23 males (24 knees) and 15 females (18 knees), aged 7-62 years (median, 32.8(More)
