PURPOSE
To compare the result of treatment between minimally invasive plate osteosynthesis (MIPO) using periarticular plate and intramedullary nailing in treatment of distal tibia fractures.
MATERIALS AND METHODS
28 cases of distal tibia fractures form Jan. 2006 to Mar. 2008 were divided into two group. Minimum follow-up was for 12 month. Group 1 consisted of 14 patients who were treated by MIPO technique and group 2 consisted of 14 patients who were treated by interlocking intramedullary nailing. The results were compared by assessing radiologic and clinical result.
RESULTS
The mean bony union time was 14 weeks (8~17) in group 1 and 15 weeks (11~20) in group 2. Operation time was 58 minutes (55~65) in group 1 and 82.7 minutes (70~100) in group 2. The average angulation in AP view was 1.5 degrees (0~2) in group 1 and 2 degrees (0~5) in group 2, in lateral view was 1.8 degrees (0~4) in group 1 and 2.3 degrees (0~12) in group 2. The average range of motion for dorsi flextion was 17.5 degrees (15~20) in group 1 and 18 degrees (16~20) in group 2, for plantar flextion was 45 degrees (42~50) in group 1 and 44 degrees (42~50) in group 2, which means that there were no severe limitation of motion in all patients, resulting in satisfactory ambulation. There was no post operative complications such as skin irritation problem caused by internal device and no implant failure and superficial wound infection.
CONCLUSION
There were no difference in bony union time, clinical result and anatomical reduction between Group 1 and Group 2 in distal tibia fractures, but operation time was shorter in MIPO than nailing.

Treatment of Periarticular Fracture of Elbow with Hinged External Fixator
Hyun Dae Shin, Kwang Jin Rhee, Kyung Cheon Kim, Chang Hwa Hong, Yong Bum Joo
J Korean Fract Soc 2005;18(3):299-303.   Published online July 31, 2005
DOI: https://doi.org/10.12671/jkfs.2005.18.3.299
AbstractAbstract PDF
PURPOSE
To evaluate the result of the treatment with external fixator and early ROM exercise to prevent the stiffness and contracture of the elbow in unstable elbow injury.
MATERIALS AND METHODS
From Jan. 1997 to Dec. 2001, ten patients of unstable elbow injury treated with hinged external fixator and early ROM exercise were evaluated. The age was average 37 years. The patients were followed at least 1 years and motorcycle injury (4 cases) was most common. Nine cases were comminuted fractures and one case was fractures with dislocation. We estimated the result of the treatment with Mayo elbow performance index.
RESULTS
ROM exercise started in average 2 days after operation. Two cases were treated by ilizarov and eight cases treated by elbow distracter modified by the author. The result of the treatment was estimated as following: excellent in two, good in three cases, fair in eight cases, and poor in two case.
CONCLUSION
There were satisfactory results in patients treated with external fixation with early ROM exercise, whose injuries had difficulty in being fixed internally. The authors recommend hinged external fixation and early ROM exercise to prevent postoperative stiffness & contracture of elbow joint in this circumference.

The Usefulness of Blocking Screw in Intramedullary Nail on Proximal Tibial Fracture
Jun Young Yang, June Kyu Lee, Young Mo Kim, Chang Hwa Hong, Kyung Cheon Kim, Sung Hwan Ahn
J Korean Fract Soc 2005;18(1):17-21.   Published online January 31, 2005
DOI: https://doi.org/10.12671/jkfs.2005.18.1.17
AbstractAbstract PDF
PURPOSE
To evaluate the effectiveness of a blocking screw in intramedullary nailing at the tibia proximal shaft fracture.
MATERIALS AND METHODS
63 tibia proximal shaft fractures from January 2000 to December 2002 treated with only intramedullary nailing were referred to as group I, and 8 fractures from January 2003 to December 2003 treated with both intramedullary nailing and the blocking screw were referred to as group II. Retrospective studies were done for group I and II. The incidence of nonunion and the postoperative angular alignments were compared. Malalignment was defined as an angle of 5 degrees anteroposteriorly or mediolaterally.
RESULTS
There were 7 nonunion (11%) in group I in compare with none in group II. There were 21 angular malalignments (33%) in group I and 1 in group II (12%) and most of them had valgus deformity or anterior anglulation. No complications were directly due to the use of the Blocking screw.
CONCLUSION
The technique of the blocking screw used to be one of the option for proximal tibial nailing at tibial proximal shaft fracture helps to overcome angular malalignments of bones.
