Objective: To analyze the long‐term effect of double‐strut bone graft for osteonecrosis femoral head (ONFH). Methods: A total 366 adult patients with ONFH in 466 hips underwent from March 1988 to January 1999. Of them, 186 206 and an average age 32.2 years (range, 20–60 years) were followed up more than five years, 2006. Based on Association Research Circulation Osseous (ARCO) classification, there 36 stage IIB, 30, 40, 32 28 IIC, IIIA, IIIB, IIIC IV, respectively. The functional results...
To explore the clinical applications of adjustable skin traction technique in treatment large area defects.A prospective study.The is largest organ human body and tissue exposed to external environment which makes it vulnerable damage. There are many reasons for defects such as trauma, infection, burns, scars, tumors resection, inflammation, pigmented nevus, etc. Skin application pulling force trunk or extremities immobilization, fracture reduction deformity correction. This accurately...
Abstract The study aimed to investigate the effect of ginsenoside Rg1 on intervertebral disc degeneration (IVDD) in rats and IL-1β-induced nucleus pulposus (NP) cells, explore its underlying mechanism. Forty IVDD rat models were divided into group, low-dose (L-Rg1) group (intraperitoneal injection 20 mg/kg/d Rg1), medium-dose (M-Rg1) 40 high-dose (H-Rg1) 80 Rg1). pathological change was observed by HE safranin O-fast green staining. expression IL-1β, IL-6, TNF-α, MMP3, aggrecan, collagen II...
Objective To study the effect of TTL dynamic stabilization(DS)system on zygapophysial joint stress(ZJS)of lumbar motive segment. Methods Six fresh adult samples were tested. The L3- L4 segment,being studied in normal and disectomy state, was stabilized by system. Insert pressure sensitive film(PSF)into space, position flexion 10°,extension 10°, left bending rotation MTS provided 400 N axial load, then unloaded after maintaining utmost load for about 1 min, pick out PSF. Repeated...
Objective To observe the effects of EPO on cell cycle and secretion NGF CNTF SCs in vitro explore how improve peripheral nerve regeneration. Methods The sciatic nerves adult New Zealand rabbits were ligated pre - degenerated. Mter a week, degenerated fetched their ectoblastics removed. We adopted method trasplant piece speed difference adhestion to cultivte purify SCs. Different concentrations added into cutures puri-fied respectively. distribution SCs.was observed by flow cytometry, level...
Objective To investigate the therapeutic efficacy of cross-fixation with three kirschner-wires on patients complex displaced supracondylar fracture humerus.Methods All fractures were reduced and fixed by inserting two kirschner wires in lateral side,followed one crossed medial wire.It was important that functional exercise after weeks plaster external fixation protection ulnar nerve operation.Results The followed up for twelve to eighteen months,all healed,three cases injury healed...
Objective To investigate the therapeutic effect of autologous bone grafting on atrophic nonunion caused by open tibia fractures with external fixation. Methods Thirty-eight patients were enrolled in this study from June 2011 to 2014 for tibial nonunion. All treated auto graft via posterior middle-crus approach after pre-operative examinations finished. Results The average operating time was 53 minutes(range, 41-67 minutes), blood loss 27 ml (range, 13-35 ml). Postoperative...
