RESUMO
BACKGROUND:Discectomy is an important therapy for lumbar disc herniation, but a smal number of patients undergoing discectomy wil relapse. OBJECTIVE:To investigate the spinal stability fol owing posterior pedicle screw fixation combined with interbody fusion cage for treatment of recurrent lumbar disc herniation. METHODS:Twenty-six patients with recurrent lumbar disc herniation from January 2007 to December 2011 were enrol ed and subjected to posterior pedicle screw fixation combined with interbody fusion cage. Pain relief and lumbar stability were observed postoperatively. We analyzed the spinal stability in recurrent lumbar disc herniation patients after posterior pedicle screw fixation combined with interbody fusion cage depending on literature search. RESULTS AND CONCLUSION:Al the 26 patients were fol owed up for 12-36 months. After treatment, al patients effectively al eviated the symptoms of low back pain, and lumbar interbody fusion was good, with a good rate of 96.2%. There was no pedicle screw loosening, broken, non-fusion phenomenon. Posterior decompression and interbody fusion cage combined with posterior pedicle screw fixation for recurrent lumbar disc herniation, characterized as fast symptom relief, strong fixation, exact interbody fusion exact, is an ideal treatment for recurrent lumbar disc herniation.
RESUMO
BACKGROUND: Expectant treatment for intertrochanteric fractures in elderly patients with osteoporosis and other chronic diseases can easily lead to complications of lying in bed.OBJECTIVE: To evaluate the results of percutaneous compression plating system (PCCP) for intertrochanteric fractures in elderly patients. METHODS: Thirty-two cases of elderly intertrochanteric fractures treated with PCCP admitted from June 2007 to June 2009 and 40 cases of elderly intertrochanteric fractures treated with dynamic hip screw system (DHS) were reviewed. The operative bleeding, operative time and curative effect were compared.RESULTS AND CONCLUSION: The operative bleeding and operative time in the patients receiving PCCP were significantly lower than those in the patients receiving DHS. There was not statistical significance between the curative effects about the two methods. PCCP applied in elderly patients with intertrochanteric fracture can get satisfactory effects, and the system is operated simply with minimally invasive surgery, which is beneficial to reduce surgical complications.
RESUMO
Objective To evaluate the curative effect of percutaneous compression plating system in treatment of intertrochanteric fractures of the elderly patients.Methods The clinical data of 18 elderly patients(aged 68-89 years)with intertrochanteric fractures were retrospectively analyzed.According to Evans classification,there were seven patients with type Ⅰ fractures,nine with type Ⅱ fractures and two with type Ⅲa fractures.Percutaneous compression plating system was applied to all patients from June 2007 to June 2009,and the therapeutic effect was evaluated by Harris hip function evaluation criteria.Results All the fractures were healed,with excellent results in 15 patients and good results in the rest three patients.Conclusions The percutaneous compression plating system is easy to manipulate with minimal invasion,has minor side effect and is beneficial to reducing surgical complications in the elderly patients with intertrochanteric fractures.
