Objective: To compare clinical efficacy between anatomical locking plate (ALP) and ordinary steel plate (OSP) in treating closed calcaneal fractures with SandersⅡ and Ⅲ., Methods: From May 2016 to May 2018, 68 patients with closed Sanders typeⅡ and Ⅲ calcaneal fractures were retrospectively analyzed, and were divided into anatomical locking plate group (ALP group) and ordinary steel plate group (OSP group) according to two kinds of plate fixation, and 34 patients in each group. In ALP group, there were 21 males and 13 females aged from 20 to 63 years old with average of (35.16±8.45) years old; 14 patients were typeⅡand 20 patients were type Ⅲaccording to Sanders classification;treated with ALP. In OSP group, there were 20 males and 14 females aged from 19 to 63 years old with average of (35.05±8.39) years old;19 patients were typeⅡand 15 patients were type Ⅲ according to Sanders classification;treated with OSP. Operative time, intraoperative blood loss and complications between two groups were observed and compared;preoperative and postoperative Böhler angle and gissane angle were also compared;American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hind foot scores, foot and ankle disability index (FADI) scores were applied to evaluate clinical effect., Results: All patients were followed up from 11 to 14 months with an average of (12.06±0.81) months. There were no statistical differences in opertive time, intraoperative blood loss, incision infection and refracture rate in complications between two groups ( P >0.05);while there was significant difference in the number of screw loosening ( P <0.05). Böhler angle and Gissane angle in ALP group at 6 and 12 months after opertaion were higher than that of OSP group ( P <0.05), and the degree of improvement of Böhler angle and Gissane angle in ALP group were also higher than that of OSP group ( P <0.05). Postopertaive AOFAS score and FADI score at 6 and 12 months in ALP group were higher than that of OSP group ( P <0.05), while no statistical difference in AOFAS grading between two groups( P >0.05)., Conclusion: Compared with OSP, ALP in treating SandersⅡ and Ⅲ calcaneal fractures could achieve better therapeutic effect, avoid screw loosening, reduce complications, and improve limb function in further.

Objective: To analysis and compare the clinical characteristics of Colles fractures between patients with osteoporotic and without osteoporotic., Methods: From June 2007 to June 2009, 260 patients with Colles fracture were reviewed, including 60 males and 200 females, with a mean age of 66.5 years old. According to Cooney classification: 44 patients were type I, 83 patients were type II, 92 patients were type III and 41 patients were type IV. Among the patients, 96 patients were osteoporotic Colles fractures, and 164 patients without osteoporotic. The general information, invalidiation rate and short-term clinical results were compared between two groups., Results: There were no statistically difference of age, gender and fracture position between the two groups. There were more patients with type III and type IV, and higher invalidiation rate in osteoporotic Colles fracture group compared to those of no osteoporotic Colles fracture group (P<0.01). At the 6 months after treatment, the clinical effects of no osteoporotic Colles fracture group was better than that of osteoporotic Colles fracture group (P<0.01)., Conclusion: The senile-osteoporotic Colles fracture has different clinical characteristics, which should be given special treatment, frequent review and communication between doctors and patients during the period of treatment.

Objective: To investigate the clinical effects and safety of vertebroplasty and kyphoplasty for the senile osteoporotic vertebral compression fractures., Methods: From December 2004 to June 2008, 28 patients (40 vertebrae) with osteoporotic vertebral compression fractures were treated with percutaneous vertebroplasty (PVP group), there were 11 males (14 vertebrae) and 17 females (26 vertebrae), with an average age of 72 years (ranged, 70 to 91 years). The fracture site of vertebral body was from T5 to L5. Other 31 patients (43 vertebrae) were treated with percutaneous kyphoplasty (PKP group), there were 13 males (18 vertebrae) and 18 females (25 vertebrae), with an average age of 74 years (ranged, 70 to 92 years). The fracture site of vertebral body was from T4 to L5. Theapeutic effects of all the patients were observed after operation, the item included visual analog scale (VAS), Oswestry score, Cobb angle, the height of anterior and middle column vertebra, and the incidence of cement leakage., Results: There was significant decrease in VAS score and Oswestry score after operation in both groups, there was significant difference between preoperative and postoperative (P < 0.01). There was no significant difference in VAS score and Oswestry score between two groups (P > 0.05). There was no significant difference in Cobb angles and the height of anterior and middle column vertebra between two groups before and after operation (P > 0.05). Among them, there were 3 vertebrae cement leakage in PVP group (7.5%) and 2 in PKP group (4.7%), but no clinical sympton occurred. There was no significant difference in the incidence of cement leakage between two groups (P > 0.05)., Conclusion: Vertebroplasty and kyphoplasty are safe and effective methods in treating senile osteoporotic vertebral compression fractures, which can restore the height of fractured vertebra, relieve pain and improve function as well as minimize the incidence of cement leakage.
