[Intervention assistant operation in treatment of phalanx closed fracture combined with artery crisis].
OBJECTIVE
To explore the effectiveness and methods of intervention assistant operation in the treatment of phalanx closed fracture combined with artery crisis.


METHODS
Between August 2002 and December 2008, 24 cases (31 toes) of phalanx closed fracture combined with artery crisis were treated. There were 17 males (22 toes) and 7 females (9 toes), aged from 16 to 62 years (mean, 38 years). The causes of injury included crush and bruise (20 cases), traffic accident (3 cases), and machine twist (1 case). The locations were the first toe (19 toes), the second toe (10 toes), and the third toe (2 toes). The period between injury and hospitalization was 1-10 hours (mean, 6.8 hours). Phalanx angiography was performed by using venous indwelling needle for dorsalis pedis artery and posterior tibial artery puncture; according to angiography results, proper treatment could be done, then the contrast medium was injected to the artery to observe the blood supply. According to different types and locations of fracture, Kirschner wire and plate were chosen to fix fracture after the blood supply were recovered.


RESULTS
Two cases (2 toes) received amputation due to necrosis at 4 days and 6 days after interventional therapy, respectively. Twenty-two cases (29 toes) survived. Incision healed primarily in 21 cases. Exudation occurred at wound of 1 case and was cured at 3 weeks after dressing change. Twenty-two cases (29 toes) were followed up 1-6 years (mean, 3.5 years) postoperatively. Two cases (3 toes) felt cool or anaesthesia and could not tolerate even in cold environment. The other toes had no senses of cold pain and paresthesia. Two cases (2 toes) had nonunion and achieved fracture healing after grafting bone. The mean union time was 4.5 months (range, 3-6 months) in other cases.


CONCLUSIONS
Intervention assistant operation is an effective measure in the treatment of phalanx closed fracture combined with artery crisis.
