Purpose Intertrochanteric fractures can be treated using proximal femoral nail antirotation (PFNA). This study examined the clinical and radiological results of the intraoperative fracture compression. Materials and Methods Ninety-four patients underwent intraoperative compression (Group I), and 88 patients underwent natural sliding only (Group II). The patients were followed-up for more than two years. All patients met the following seven conditions: (1) AO/OTA 31-A1, A2 type intertrochanter fracture, (2) availability of compression of more than one cortical bone in the anterior or medial region of the fracture site under the preoperative imaging test, (3) Singh index grade ≥3, (4) blade position: center-center, center-inferior, (5) tip-apex distance <25 mm, (6) reduction status of good or very good, and (7) positive or neutral medial cortical support position with slightly valgus reduction. Results A slight tendency toward significant differences in acute phase pain between the two groups was observed at six weeks postoperatively (p=0.073). Twenty-four months after surgery, lateral extension of the PFNA helical blade between the two groups showed significant differences (p=0.017). Fracture gaps measured immediately after surgery showed significant differences (p=0.001), and a clear tendency for a significant difference in the average fracture union time was found (p=0.065). Conclusion Intraoperative fracture compression, intraoperative fracture compression appears beneficial to achieve a successful union of trochanteric fractures provided that all conditions are met to apply the method safely.

PURPOSE To analyze the clinical and radiologic results of treatments in proximal femoral fracture with Proximal Femoral Nail-Antirotation (PFNA). MATERIALS AND METHODS We retrospectively reviewed the results of 21 cases of proximal femoral fracture treated with PFNA from September 2006 to October 2007 which could be followed up for minimum of more than a year. The mean age was 61.5 (20~88) years old. Male were involved in 12 cases, female in 9 cases. The mean follow up was 14.3 (12~18) months. The Garden alignment index, Cleveland index, tip apex distance were evaluated by post-operative radiologic evaluation and complications of bone union, failure of internal fixation and deformity were evaluated by follow up radiologic findings. Clinical results were assessed by social function score of Jensen and mobility score of Parker and Palmer at last follow up. RESULTS All fractures were united and the mean time to bone union was 15.7 (13~18) weeks. Garden alignment index showed good results of above 'good' in 15 cases (71.4%), Cleveland index showed 14 cases (66.4%) positioning in zone 5 and tip apex distance showed 17.81 (+/-5.65~27.52) mm in radiologic findings. The mean sliding of blade was 1.32 (0.34~2.94) mm in follow up radiologic findings and fracture of distal locking screw area was found in 1 case as a complication. Among 21 cases, the function before injury was completely recovered in 15 cases (71.4%) which were assessed by social function score of Jensen and 13 cases (61.9%) by mobility score of Parker and Palmer. CONCLUSION We think that PFNA is effective osteosynthetic device for proximal femur fracture with satisfactory radiologic and clinical outcomes.

The factors that determine whether a proximal femoral fracture is neck or trochanteric area are a matter of controversy. So we studied the BMD(bone mineral density) and the morphology of the contralateral femur in subcapital fracture and intertrochanteric fracture(Boyd - Griffin Type I,II). The bone density of femoral neck, Ward's triangle and trochanteric region was measured by dual energy X-ray absortiometry(DEXA) in 41 patients with femoral neck fracture value and fracture type in same patients, we calculate the femoral neck length from the plain X-ray film. The results were as follows.
1. The ratio of BMD in the neck and trochanter area was higher in the trochanter fracture group.
2. The level of BMD of the trochanter fracture group was lower than the neck fracture group in all opints of measurement.
3. In the measurement of femoral neck length at plain X-ray film, the neck length of trochanter fracture group was longer than the neck fracture group. It may be that difference in BMD and femoral neck length is related to the site at which a proximal femoral fracture occurs.
Closed intramedullary nailing is a complex technique which usually requires fracture table and image intensifier, so that the patient and surgeon are exposed to the radiation. But this technique affords considerable advantages such as high rate of union, less infection rate and early weight bearing, etc. The main causes of failure or complication of this procedure are inapproprisate entry point and inadequate nail size. These are especially important problems in the patient who is femoral canal diameter is very small (8 or 9mm). The Delta femoral interlocking nails (diameter 10mm and 11mm)were devised for the femurs with narrow canal diameter. However, proximal portion of the Delta nail (about 7cm from the proximal end)is thick (diameter 13mm)to gain strength enough for holding the insertion device and fixation of the interlocking screws. If the insertion point is not correct or proximal reaming is inadequate, iatrogenic proximal femoral fracture may occur during final insertion of the nail. We experienced 2 cases of this complication during fixation of femoral shaft fractures using the Delta nails. We managed thls problem with hip spica cast immobilization in one case, and multiple pinning of femur neck in the other.
