ABSTRACT
Objective To investigate the effect of self-designed closed negative pressure drainage combined with sponge dressings on refractory wounds.Methods Sixty patients with phase III-IV pressure ulcers were randomly divided into experiment group and control group in equal number.The self-designed closed negative pressure drainage combined with sponge dressing was applied in the experiment group and in the control group the conventional dressings were used.The two groups were compared in terms of hyperplasia of fresh granulation tissue,time for filling the defect and the healing time and the medical expense.Results Compared to the control group,the time for hyperplasia of fresh granulation tissue,the time for filling the defect and the healing time in the experiment group were all significantly shorter,and the medical expense of the experiment group was significantly less(all P<0.01). Conclusion The self-designed closed negative pressure drainage combined with sponge dressings in the treatment of phase III-IV refractory pressure ulcers may effectively shorten the healing time,improve the curative effects and reduce the economic burden of patients.
ABSTRACT
Objective To summarize the therapeutic effect of minimally invasive percutaneous plate esteosynthesis (M1PPO) with less invasive stabilization system (LISS) in distal femoral fractures. Method Twenty-eight patients with LISS in distal femoral fractures between June 2004 and May 2005 were analyzed retrospectively. Results The average following up period was ( 17.6 ± 0.1 )months (6-30 months) all 28 cases,only one case of delayed union,the others were no complications. According to Johner-Wruh score standard,28 cases were excellent 16,good 9,fair 2 and poor 1,the rate of excellent and good was 89.3%. Conclusion The therapeutic effect of MIPPO with LISS in distal femoral fractures is satisfactory.
ABSTRACT
Objective To compare the effect of hip artificial replacement and DHS internal fixation for the treatment of intertrochanteric fracture, and investigate the difference of the two method. Methods Eighty-six pa- tients with intertrochanterie fracture patients were treated with hip arthroplasty, and dynamic hip screw. The pa- tients were followed up for 6 months, and compared the operation rime, blood loss, postoperative complications, sur- vival rate, postoperative hip function score and lose situation. Results There was no significant difference in opera- tion time,blood loss,postoperative complications,in local symptoms hip varus deformation occured in the DHS inter- hal fixation because lag screw cut-our and the collapse of the medial cortex, hip and thigh pain oecured in artificial re- placement,hip function score dropped 9.5 % in DHS and 9.2% in artificial replacement. Conclusion For elderly patients, eomminuted fracture and osteoporosis, and other types of unstable intertrochanteric fracture patients, the primary purpose of surgery is to provide to patients more activities of the early conditions,so hip arthroplasty can be used to the treatment of intertrochanteric fracture,as a reasonable replacement surgery.
ABSTRACT
Objective To analyze the effect of clavicular hook plate(CHP) in treating distal clavicular fracture and acromioclavicular joint dislocation. Methods Eighteen patients with distal clavicular fracture(NeerⅡ) and acromioclavicular joint disclocation(Tossy Ⅲ) were treated by CHP. Results Sixteen patients were observed after operation,according to Lazzcano curative effect standard, fifteen cases were excellent, take 93.75 percent,1 case was good, with 6.25 percent, the excellent and good rates were 100.00 percent. The phenomenon such as the steel plate fracture,loose,escape hook and acromioclavicular joint re-dislocation were not happened. Conclusion CHP is an effective,scientific and convenience way for distal clavicular fracture and acromioclavicular joint dislocation,it worth being promoted.
ABSTRACT
Objective To investigate the relation between plasma matrix metalloproteinase 9 (MMP 9) levels and transcranial Doppler (TCD) detected microemboli in patients with cerebral infarction and evaluate the clinical significance. Methods The plasma MMP 9 levels were quantified by ELISA and the microemboli were detected with TCD in 50 stroke patients and 20 controls. Results The level of plasma MMP 9 was significantly higher in microembolic signal positive patients than that in negative ones [median (392.87?210.90) ng/ml for those with emboli versus (202.27?153.40) ng/ml for those without, P
