Analysis of Affecting Factors of Fixation Failure of Femoral Neck Fractures Using Internal Fixation: Soo Jae Yim, Seung Han Woo, Min Young Kim, Jong Seok Park, Eung Ha Kim, Yoo Sung Seo, Byung Il Lee; J Korean Fract Soc 2006;19(3):297-302. Published online July 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.3.297

PURPOSE
To evaluate the factors which influence on the fixation failure after internal fixation using multiple cannulated screws in the patients with femoral neck fracture.
MATERIALS AND METHODS
Ninty-six patients (male: 63, female: 33) who underwent closed reduction and internal fixation of femoral neck fracture between Feb. 1994 and Jun. 2002 with use of multiple cannulated screws. The mean age was 68 years (17~90) and mean follow-up period was average 50 months (36 months~6 years). The fixation failure was defined by change in fracture position above 10 mm, change in each screws position above 5%, backing above 20 mm, or perforation of the head, respectively. They were evaluated with the age, gender, fracture type, accuracy of reduction, placement of screws, posterior comminution and also studied the risk factors which influenced nonunion and the development of avascular necrosis.
RESULTS
Twenty-four patients out of 96 patients had radiographic signs of fixation failure. The incidence of nonunion in the fixation failure group was 41% (10/24) and AVN was 33% (8/24). There were statistically significant correlations between fixation failure and nonunion and that posterior comminution, poor reduction and improper placement of the screws were the major factors contributing to nonunion.
CONCLUSION
In case of femoral neck fracture of internal fixation using multiple cannulated screws, posterior comminution, poor reduction and improper placement of the screws were the major factors contributing to nonunion and fixation failure.

Impacted Cancellous Allograft and Quadratus Femoris Pedicle Bone Graft of Femoral Neck Fracture Nonunion: Soo Jae Yim, Seung Han Woo; J Korean Soc Fract 2002;15(4):519-525. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.519

Abstract PDF: PURPOSE
The aim of this study was attempted to evaluate the effects of impacted cancellous allograft and quadratus femoris pedicle bone graft in the management of nonunion of femur neck fracture.
MATERIALS AND METHODS
Between March 1998 and April 1999, 5 patients, rating from 36 to 45 years of age, were treated with impacted cancellous allograft and quadratus femoris pedicle bone graft and all cases were nonunion with displaced transcervical fracture whose primary treatment had been done with closed reduction and multiple pinning. The duration of follow-up was from 36 months to 48 months and the mean follow-up period was 40 months. Clinical evaluation was done according to Lunceford functional results and radiologically bone union was evaluated by 3 monthly X-ray check.
RESULTS
After follow-up from 36 months to 48 months, all cases resulted in the bone union. Four cases, radiologically bone union was progressed during 14 weeks, and the other, obtained at 6 months. All cases, at 18 months, radiologically complete bone union was obtained. Clinical result was above fair results and no one complaints pain and instability.
CONCLUSION
For patients with nonunion of femoral neck fracture, impacted cancellous allograft and quadratus femoris pedicle bone graft was provide a good result of union.
