The Usefulness of Poller Screw with Antegrade Nailing in the Initial Treatment of Infraisthmal Femur Shaft Fracture: Jeong Hyun Yoo, Hyoung Soo Kim, Chang Geun Kim, Ho Il Kwak, Sang Heon Song; J Korean Fract Soc 2015;28(4):230-236.

Abstract PDF: PURPOSE
The purpose of this study was to evaluate the radiologic and clinical outcomes after intramedullary nailing with Poller screw insertion at initial stage in infraisthmal femur shaft fractures.
MATERIALS AND METHODS
Seven consecutive patients (7 femurs) treated with antegrade intramedullary nailing with Poller screw insertion for the infraisthmal femur shaft fracture were reviewed retrospectively. There were 4 male and 3 female patients. Mean age was 46.1 years (20-72 years). Operative time including Poller screw insertion, time for union, malalignment, and range of motion were evaluated.
RESULTS
All 7 cases had primarily healed successfully. Mean time for radiologic union was 19.1 weeks (16-24 weeks) postoperatively. One case had 5 degree valgus malalignment. One case of 15 mm shortening was reported and he required shoe lift orthosis. All cases had a full range of motion in hip and knee joint.
CONCLUSION
Antegrade intramedullary nailing with Poller screw insertion is useful in the initial treatment of infraisthmal femur shaft fracture, because it could provide additional stability. An additional 20 minutes were required but a Poller screw should be considered according to the anatomic location of a femur shaft fracture.

Treatment of Proximal Shaft Fracture of Tibia with Intramedullary Nail: Analysis According to AO Classification and the Poller Screw: Chang Wug Oh, Sung Jung Kim, In Ho Jeon, Hee Soo Kyung, Byung Chul Park, Joo Chul Ihn, Kyung Hoon Kim, Yun Kee Woo; J Korean Fract Soc 2004;17(2):133-137. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.133

PURPOSE
This was a retrospective study to evaluate the results of intramedullary nailing in proximal shaft fracture of tibia. We analyzed those results according to AO classification and Poller screw.
MATERIALS AND METHODS
Thirty-three proximal tibial shaft fractures (32 patients) were followed for more than one year. In AO classification, there were 6 cases of type A, 14 cases of type B, and 13 cases of type C. We used Poller screws in 14 operations. We evaluated translation, angulation and nonunion after surgeries.
RESULTS
Twenty-eight cases (85%) were united primarily, but nonunions occurred in 5 cases. Malalignment (angulation>5degree or translation>5 mm) was found in 14 cases (42%). In Poller screw used and non-used groups, the malalignment was respectively showed in 2 cases (14%) and 12 cases (63%). According to AO classification, nonunion was found in only type B with 5 cases (36%).
CONCLUSION
Intramedullary nailing of proximal shaft fracture of tibia showed relatively lower rate of primary union. Especially, when initial fractures have a butterfly fragment, it showed the higher rate of nonunion. Moreover, the malalignment rate was relatively higher, yet it is possible to reduce the rate of malalignment by using Poller screw.
