Factors Affecting Posterior Angulation in Retrograde Intramedullary Nailing for Distal Femoral Fractures: Hohyoung Lee, Ji Ho Jeong, Min Su Kim, Bum Soo Kim; J Korean Fract Soc 2018;31(2):50-56. Published online April 30, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.2.50

Abstract PDF: PURPOSE
To analyze the factors that cause a posterior angulatory deformity in the retrograde intramedullary nailing of distal femoral fractures.
MATERIALS AND METHODS
Fifty-five patients with distal femur fractures who were treated with retrograde intramedullary nailing were enrolled in this study. They were followed-up for at least one year postoperatively. The posterior angulatory deformity was evaluated according to the fracture location, pattern, and insertion point and the insertion point was compared with the ideal point derived from the radiographs of 100 normal adults. The correlation between the posterior angulation and the entry point of the nail was analyzed.
RESULTS
The posterior angulation was similar in terms of the fracture location; a meaningful difference was noted among the fracture patterns (p=0.047). The posterior angulation was significantly greater when the entry point was located more posteriorly, accepting a malreduced state (p=0.012).
CONCLUSION
Posterior angulation was smaller in the transverse fracture and the posterior location of the entry point from the apex of the Blumensaat's line increased the posterior angulation.

Treatment of Periprosthetic Femoral Fractures Following Total Knee Arthroplasty: Lih Wang, Kyu Yeol Lee, Chul Hong Kim, Myung Jin Lee, Min Soo Kang, Jin Soo Hwang, Sun Hyo Kim; J Korean Fract Soc 2014;27(1):42-49. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.42

PURPOSE
The purpose of this study is to compare the treatment results of fracture fixations by using two minimal invasive techniques for patients with periprosthetic femoral fractures following total knee arthroplasty.
MATERIALS AND METHODS
We reviewed 36 patients (5 males, 31 females) of periprosthetic femoral fractures whom were treated surgically between January 2005 and January 2011. Mean patient age was 68.9 years (range, 43 to 81 years) old and the follow-up period averaged 41 months (range, 18 to 72 months). Nineteen patients were treated with minimal invasive locking plate fixations (group I) and 17 patients with retrograde intramedullary nailing (group II). Clinical and radiological outcomes in each group were comparatively analyzed.
RESULTS
Successful bone unions occurred in all patients and the mean time to bone union was 3.7 months in group I and 4.2 months in group II. There were no statistical differences between the two groups according to mean operative time and mean intraoperative blood loss. There were also no statistical differences between two groups according to clinical outcomes but the valgus deformity was apparent in group II and radiological outcomes revealed significant differences between the two groups.
CONCLUSION
For the treatment of periprosthetic femoral fractures after total knee arthroplasty, two minimal invasive techniques have shown good clinical results. However, the minimal invasive plate fixation showed better results in the radiological alignments.

Abstract

PURPOSE
To evaluate the effectiveness. analyze the result after retrograde intramedullary (IM) nailing in femoral shaft fracture MATERIALS AND METHODS: Thirty-four femoral shaft fracture (32 patients) were operated with retrograde IM nail and followed the result for more than 18 month from march 2001 to march 2003. There were 6 of femoral mid shaft fractures and 28 of distal femur fractures. According to AO classification, there were 1 of A1, 1 of A2, 2 of A3, 2 of C1 in femoral mid shaft fracture and 11 of A1, 7 of A2, 7 of A3, 1 of B1, 2 of C1 in distal femur fracture. They included 5 open fracrures. By Gustilo classification there were 3 of type I, 2 of type II. Through radiologic study we evaluated the time of union, nonunion, malunion. And in clinical evaluation we checked knee function in 18 month after operation.
RESULTS
It took 16 weeks (range 12~20 weeks) for average bone uion period. 30 cases out of 34 cases had the bone union but 4 cases showed nonunion. There were not any complication except 3 cases of screw migration. Full rage of motion was gained in 29 cases. However knee stiffness occurred in 5 cases. The knee function through knee score was assessed by showing 28 of excellent, 1 of good, 5 of poor.
CONCLUSION
Even though the retrograde intramedullary nailing may have some defect to be able to damage to knee joint in operating, It can be useful surgical technique for femoral shaft fracture in such as ipsilateral fracture or multiple fracture, poor general condition, and so on.

Abstract PDF

PURPOSE
To evaluate the results and complications of the retrograde intramedullary nailing for the treatment of distal femur fracture.
MATERIALS AND METHODS
Thirty three patients who received retrograde IM nailing for fractures of the distal femur between October 1998 to December 2003. Average age was 53.8+/-17 (17~86) years. The average follow up period was 19.4 (12~36) months. Clinical information included age, sex distribution, associated fracture and fracture was classified by AO classification. Functional result was evaluated by Schatzker's criteria.
RESULTS
The most common cause of injury was traffic accident (60%). The type of fracture were 6 A1 cases, 5 A2 cases, 11 A3 cases, 5 C2 cases, 6 C3 cases by AO classification. Among the 33 cases, 15 cases were excellent, 9 good, 6 fair and 1 failure according to Schatzker's criteria. Average union time was 9.7+/-3.5 months.
CONCLUSION
Treatment of distal femur fracture with retrograde intramedullary nailing was useful due to its minimal invasiveness and early range of motion, more rigid fixation.

Abstract PDF

PURPOSE
We analyzed the cases of supracondylar-intercondylar femoral fracture treated with retrograde intramedullary nail and report the clinical results and its usefulness.
MATERIALS AND METHODS
We reviewed 17 cases of supracondylar-intercondylar femoral fracture that had been treated with retrograde intramedullary nail and each of patients had been followed up for a minimum one year. Post-operative functional assessment was performed using a scale developed by Sanders et al. The evaluation scale assesses range of motion, pain, walking ability, return to work, and alignment and shortening as measured on radiograph.
RESULTS
According to functional assessment of Sanders et al, there were 6 excellent, 9 good, 1 fair, and 1 poor results, that is, 94% showed above excellent results. Bony union was obtained in average 5 months after operation. The post-operative complications were varus deformity in 1 case, wound infection in 1 case, stiffness of knee joint in 1 case, and metal failure in 1 case.
CONCLUSION
The treatment of supracondylar-intercondylar femoral fracture with retrograde intramedullary nail is one of the good surgical options for clinically preferable results with the advantages in early joint motion and early ambulation.

Abstract PDF

PURPOSE
Retrograde intramedullary nailing has been recommended as one of the treatment options for the distal femoral fracture, particularly in patients who are obese, are pregnant, has sustained ipsilateral femoral neck fracture, have multiple injuries. However there are some disadvantage such as post-arthrotomy infection, knee joint stiffness. This paper is to evaluate the result and complication of treatment of distal femoral fracture with a retrograde intramedullary nailing.
MATERIALS AND METHODS
We reviewed 13 cases (distal femoral shaft fracture: 6 cases, supracondylar fracture: 7 cases) of the distal femoral fracture who had been treated with retrograde intramedullary nailing and follow up for more than 12 months from January 1999 to December 2001. The rate of bony union, range of motion of the knee, complications were evaluated.
RESULTS
The mean duration of bony union was 20 weeks (range, 16~25 weeks). A case of delayed union was developed. In 4 cases of 13 cases showed posterior angulation below 6 degree, which did not need further treatment. According to Saunder's criteria, excellent result was achieved in 8 patients, good result in 5 patients, respectively.
CONCLUSION
This study showed good clinical and radiological results of union with retrograde intramedullary nailing at the distal femoral fracture and ipsilateral multiple fracture

Retrograde Intramedullary Nail for Femoral Shaft Fracture with Limited Indications: Sung Jung Kim, Chang Wug Oh, Joo Chul Ihn, Hee Soo Kim, In Ho Jeon, Hee Soo Kyung, Il Hyung Park, Kyung Hoon Kim; J Korean Soc Fract 2003;16(1):45-51. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.45

Abstract PDF

PURPOSE
This is a retrospective study to analyze the results after retrograde intramedullary(IM) nailing in femoral shaft fractures with limited indications.
MATERIALS AND METHODS
Twenty-four femoral shaft fractures(21 patients) were operated with unreamed IM nail(Unreamed femoral nail, SynthesR) in a retrograde method and were followed for more than 1 years. There were 16 men and 5 women, and the mean age at index operation was 41 years (range 18-76 years). In Winquist-Hansen classifications, there were 10 of type I, five of type II, three of type III, and six of type IV. All the patients had associated fractures or injuries, and there were eight ipsilateral tibia fractures, five ipsilateral proximal femoral fractures(including neck and trochanter), four ipsilateral pelvic or acetabular fracture, three bilateral femoral fractures, and one ipsilateral knee injury according to the used indications. In radiological study, we evaluated the time for union, non-unions and malunion, and clinical evaluation with Neer 's criteria was done.
RESULTS
Most fractures(87.5%) were primarily united cases, and the mean time for union was 15.8 weeks(range 12-20 weeks). Three cases of delayed union or nonunion were developed, but a shortening over 1cm or malunion over 10 degrees angular deformity were not found. Evaluating the knee functions, the Neer score was 86.9 in average and all the cases were above satisfactory grade. The average range of knee motion was 120.2 degrees, and the mild knee pain was developed in three cases.
CONCLUSION
The retrograde IM nailing can be a useful option for femoral shaft fractures with limited indications, including ipsilateral fractures of other areas or multiple fractures.
