ABSTRACT
Objective@#To evaluate the method and curative effect of plate fixation or percutaneous screws for the treatment of calcaneal fractures of Sanders type Ⅱ and Ⅲ via a minimally invasive sinus tarsi incision combined with a variety of manipulative reduction methods.@*Methods@#Twenty-one patients with closed calcaneal fractures treated in the Department of Orthopedics, the First Affiliated Hospital of Nanchang University from January 2014 to January 2016 were collected. There were 15 men and 6 women, with an average age of 39.3 years(from 25 to 63 years). According to the Sanders classification, 16 cases were type Ⅱ and 5 were type Ⅲ.All cases were treated with internal fixation with plate and percutaneous screws via the mini-open sinus tarsi approach following reduction of the posterior articular surface of the subtalar joint and calcaneal length, width and height.Statistical analysis was performed on calcaneal width and Böhler angle, Gissane angle preoperatively and postoperatively (3 days and 3 months). All data were analyzed by ANOVA, functional recovery was evaluated according to the Ankle and Hind-foot Score of American Orthopedic Foot and Ankle Society (AOFAS).@*Results@#Twenty one patients were followed up for a mean duration of 13.4 months(6 to 24 months). All cases gained primary incision healing, without complications such as skin necrosis, wound infection, tenosynovitis of peroneus longus and brevis muscles, or fracture displacement and hardware failure.Bone union was achieved at an average of 10.5 weeks(9 to 11 weeks). No obvious malunion occurred by the last follow-up. Compared to preoperative, calcaneal width(F=25.62, 38.90) were significantly improved 3 days and 3 months after surgery, Böhler angle(F=440.24, 272.42) and Gissane angle(F=91.86, 43.74) were normal, the differences were statistically significant (all P<0.05). Compared to 3 days after surgery, calcaneal width, Böhler angle and Gissane angle kept normal 3 months after surgery, there were no statistically differences (F=0.26, 1.35, 2.60, all P>0.05). By the AOFAS scoring, 10 cases were rated as excellent, 7 were good and 4 were fair.@*Conclusions@#Fixation with plate and percutaneous screws via the mini-open sinus tarsi approach is an effective treatment for Sanders types Ⅱ and Ⅲ calcaneal fractures, which with the advantages of small wound, simple operation, reliable fixation, no incision complication, especially suitable for elderly patients and the patients with severe injury of local soft tissue.
ABSTRACT
OBJECTIVE To understand and use reasonably the strategy of prevention and management of overwhelming postsplenectomy infection(OPSI). METHODS According to intervention to patients with postsplenectomy by means of education,vaccination,antibotic prophylaxis after April 1998,clinical and follow-up data were reviewed and analyzed from 337 cases patients with traumatic splenectomy from Jan 1992 to Jan 2004,and correlative factors of four OPSI cases were further analyzed. RESULTS Incidence of OPSI descended obviously after intervention(P
