OBJECTIVES: To analyze the characteristics and mechanisms of pelvic fractures in the cases of road traffic accident deaths. METHODS: Total 65 cases of road traffic accident deaths with pelvic fracture were collected, and the sites, characteristics and injury mechanisms of pelvic fracture were statistically analyzed. RESULTS: Among the 65 cases of pelvic fracture, 38 cases of dislocation of sacroiliac joint were found, and most combined with pubis symphysis separation or fracture of pubis. In the fractures of pubis, ischium and acetabulum, linear fractures were most common, while comminuted fractures were most common in sacrum and coccyx fractures. There were 54 cases combined with pelvic soft tissue injury, and 8 cases with pelvic organ injury and 44 cases with abdominal organ injury. In the types of pelvic ring injury, 32 cases were separation, 49.32%, followed by compression, 26.15% and only one case was verticality, 1.54%. CONCLUSIONS Detailed and comprehensive examination of the body and determination of the pelvic fracture type contribute to analyze the mechanisms of injury.

OBJECTIVETo treat the comminute distal radius fractures by improved splint, and obersve the curative effect and compare the radiology with the traditional splint.

METHODSNinety-two patients with distal radius comminute fracture were randomly divided into two groups. There were 38 males and 54 females. The average age was 63 years old ranging from 23 to 82. Acording to AO classification on the distal fracture of the radius, there were 15 cases of A3, 40 cases of C1, 26 cases of C2 and 11 cases of C3. After all patients were treated by manipulative reduction, 46 cases of the treatment group were fixed supra-carpometacarpal joints by improved splint and trapezoid pad, the other 46 cases of control group were treated with the traditional spilint. Both groups were regularly taken X-ray recheck and changed dressings to obtain the clinical cicatrization. Patients were guided to do functional exercise after splints were taken off. Six weeks later all patients were evaluated the curative and radiologic effect according to Gartland-Werlley wrist score and Lidstrom grade respectively.

RESULTSAccording to wrist score,there were 13 cases on excellent, 34 cases on fine and 9 cases on normal in treatment group, which average score was (4.0 +/- 2.6) and the percent of wrist functional fitness was 80.6%. There were 9 cases on excellen, 19 cases on fine and 18 cases on normal in control group, which average score was (6.0 +/- 4.2) and the percent of wrist grad and 4 cases on the third grade in treatment group. There were 22 cases on the first grade, 16 cases on the second grad and 8 cases on the third grade in control group.

CONCLUSIONThe outcome of improved splint was better than that of traditional splint on the function and radiology for treating the comminute distal radius fracture.

OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

OBJECTIVE: To study the characteristics of forensic identification of phalangeal fracture and to use a combination of medical records, imaging materials, and forensic examination data in identification. METHODS: Fifty cases of phalangeal fracture involved in the forensic identification were collected from 2009 to 2011. The general situation, the distribution of fracture, the fracture morphology, the injury-causing objects and the results of identification were analyzed retrospectively. RESULTS: Majority of the cases of phalangeal fracture were young and middle-aged men. The index finger and distal phalanx fractures were common. There was no difference in the number of phalangeal fracture between left and right hand. Most of the injury-causing objects were knives and sticks, followed by bricks and stones. CONCLUSION The injury-causing objects and modes are related to the morphology of fracture, the distribution of fracture and the severity of the injury. The comprehensive analysis is helpful in forensic identification of phalangeal fracture.
