OBJECTIVE: To investigate the clinical outcomes of C-arm X-ray fluoroscopy before incision to make assistant lines and insert the guide wire of PFNA and PFNA blade.
METHODS: From January 1st 2012 to January 1st 2015, 132 intertrochanteric fracture patients of type 31A1 and 31A2 according to AO-classification, were retrospectively analyzed. Among them, 62 patients(14 males and 48 females) aged from 52 to 95 years with a mean age of(69.58±8.55) years in traditional group were operated by traditional procedure, while 70 patients in the skin marking group included 15 males and 55 females aged from 61 to 88 years with a mean age of(71.94±7.64) years, on the basis of the traditional operation method, the assistant line of the body surface and the C-arm X-ray was increased, and the guide pin positioning of the proximal femoral nail and the spiral blade was guided by the auxiliary line in the operation. Operative time, frequency of C-arm fluoroscopy, Harris hip score of the third months after surgery and the complications in both groups were queried for statistical analysis.
RESULTS: In addition to skin making group 1 patients had superficial wound infection complications, all patients were stage I wound healing. All patients were followed up for 3 to 18 months with an average of (6.81±3.07) months. The operative time was significantly reduced in skin marking group (56.16±6.36) minutes compared to traditional group (59.06±9.19) minutes (P>=0.035). And the frequency of C-arm fluoroscopy of skin marking group was(25.89±5.81) times which was also significantly reduced compared to traditional group(31.32±9.81) times (P<0.001). There was no statistical difference in Harris hip score at 3 months after operation and the complication rate between the two groups(P>0.05).
CONCLUSIONS: In this study, a simple and easy method of assistant line marking can shorten the operation time and reduce the number of times of operation.
