PURPOSE
To report the postoperative Clinical and Radiological outcomes following distal femoral fractures in elderly patients compared with young patients.
METHODS
From March, 1996 to March, 2012, 83 patients who received surgical treatment for fractures of the distal femur were enrolled in this retrospective study. Ages more than 65 was named group A. Group A was 49 cases and mean age is 72.5 year(65~91year). Group B was 49 cases and mean age is 45.7 year(16~61 year). Surgical methods are retrograde IM nail, locking compression plate, cannulated screw and postoperative rehabilitation is no difference between two groups. Clinical results were evaluated using Neer scores, radiographic results and the presence of clinical complications.
RESULTS
The mean union period was 18.4(12-40) weeks in group A and 17(10-24) weeks in group B. Neer functional scores are no significant statistical difference between two groups. There are 5 cases metal breakage in group A and 1case in group B. There are 3 cases nonunion in group A and 1 case in group B.
CONCLUSION
In the case of fractures of the distal femur in elderly patients, locking plate using minimally invasive percutaneous periosteal osteosynthesis (MIPPO) technique may be one of the most effective methods and preoperative bone stock evaluation in important.

AbstractAbstract PDF
PURPOSE
Among patients with multiple traumatic fractures, a tendency to form more callus exists in groups with multiple fractures combined with traumatic brain injury. This retrospective study evaluated the hematologic factors that might be useful to predict callus formation by comparing serologic tests and clinical and radiologic results in two groups.
METHODS
From January 2000 to December 2010, patients with femur shaft fractures were divided in two groups: one without traumatic brain injury (control group: 32 cases), and the other with traumatic brain injury (study group: 44 cases). We evaluated routine serologic exams and the amount of callus formation during the follow-up period.
RESULTS
Only the alkaline phosphatase level was statistically different between the two groups, not the White blood cell count, C-reactive protein, total calcium, and lactate dehydrogenase level. The amount of callus formation on the antero-posterior radiograph at the last follow up period was 74.9% in the study group and 42.1% in the control group. Then lateral radiograph showed 73.2% callus formation rate in the study group and 31.8% in the control group.
CONCLUSION
In routine serologic exams, the two groups had no significant differences, except for the alkaline phosphatase level. The group with traumatic brain injury had much more callus formation, but there was no reliable factor to predict callus formation on the routine serologic exam.
