Objective: To analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction., Methods: From January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction., Results: Among 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85)., Conclusion: The dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

Objective: To explore clinical characteristics and replantation methods of degloving injury of distal finger., Methods: From 2004 to 2009,18 cases of 19 distal finger degloving were admitted, and included 14 males and 4 femals with an average age of 31 years old ranging from 18 to 51 years old. The distal finger degloving injury was divided into 3 types according to the different levels of degloveing digital artery and skin involving 6 fingers of type I, 10 fingers of type II, 3 fingers of type III. Among them, 3 cases of 4 fingers were failed to be replantaed due to severed injured digital artery, and 15 cases of 15 distal finger degloving injury were replanted with microsurgical technique., Results: Among 15 patients (15 fingers) conpleted the reimplant operation, 13 fingers were survived, 2 fingers were necrosis after operation. Thirteen survived fingers were followed up from 6 to 24 months (averaged 14 months). The appearance of injured fingers and nails obtained satisfactory results. According to Chinese Hand Surgery Society Criteria for function assessment replantation, the results were excellent in 9 cases, good in 3 cases and poor in 1., Conclusion: Replantation of distal degloving injury is effective and it should strive for replantation.
