The Angulation as to the Location of the Lag Screw of Compression Hip Screw in the Intertrochanteric Fracture of the Hip: Sang Won Park, Kwang Jun Oh, Seung Yong Wang; J Korean Soc Fract 2002;15(1):15-20. Published online January 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.1.15

Abstract PDF: PURPOSE
The purpose of this study was to evaluate the change of the angulation deformity according to apposition of medial cortex and sliding mechanism as to the location of the lag screw in the intertrochanteric fracture of the Korean femur which neck-shaft angle is relatively small .
MATERIALS AND METHODS
We selected the patients those angulation of femur neck-shaft was within 5 degree in comparison with normal side, and displacement of fracture fragment was within 4mm on the immediate post-operative radiograph. According to Evans classification, all patients were type I fracture. We classified the patients in two groups -stable medial cortex apposition(Group I) was 13 cases, and unstable no apposition(Group II) was 16 cases.
RESULTS
In the Group I, the varus-valgus angulation was average 3.3 degrees when lag screw was positioned at the middle of the femur neck, average 3.6 degrees when lag screw was positioned at the inferior to the femur neck. In the Group II, the varus-valgus angulation was average 6.1 degrees when lag screw was middle of the femur neck, average 1.5 degrees when lag screw was inferior to the femur neck.
CONCLUSION
There is no difference in angulation deformity when the lag screw is inferior or middle of femur neck if medial cortex is contacted, but the angulation deformity is less when the lag screw is inferior to femur neck if medial cortex is not contacted, in intertrochanteric fracture.

The Effectiveness of Bone Scintigraphy of Femur neck fracture: Sang Won Park, Seung Beom Han, Soon Hyuck Lee, Woong Kyo Chung, Seung Yong Wang; J Korean Soc Fract 2001;14(3):323-330. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.323

PURPOSE
To evaluate the effectiveness of bone scintigraphy using 99mTc-methylene diphosphonate(99mTc-MDP) for prediction of viability of femoral head in femur neck fracture that have been treated with osteosynthesis.
MATERIALS AND METHOD
Thirty two patients were included in this study who underwent preoperative and postoperative bone scintigraphy using 99mTc-MDP following femur neck fracture. The uptake of istope was estimated visually as either normal or reduced compared with the opposite side. The complications as avascular necrosis and non-union were checked and compared with the preoperative and postoperative bone scintigraphy and the predictive values of positive and negative scintigraphy were calculated.
RESULTS
Among thirty-two patients, bone union occured in nineteen patients except 12 avascular necrosis and 1 non-union. Average bone union peried was 4.4 months and 50% was occured between 3 and 6 months. In seventeen patients who showed reduced isotope uptake, twelve patients developed complications and predictive value of positive scintigraphy was calculated as 0.76. In fifteen patients shown normal isotope uptake, none developed complications and predictive value of negative scintigraphy was calculated as 1.00.
CONCLUSION
Preoperative bone scintigraphy using 99mTc-MDP was useful method to evaluate the viability of femoral head following femur neck fracture and to choose the treatment modality of displaced femur neck fracture especially in elderly person.

The Result of Modified Bankart Operation with Suture Anchor in Traumatic Recurrent Anterior Dislocation of Shoulder Joint: Kwang Suk Lee, Jung Dae Seo, Kwang Jun Oh, Seung Joon Lee, Seung Yong Wang; J Korean Soc Fract 2001;14(3):484-490. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.484

Abstract PDF

PURPOSE
The purpose of this study was to evaluate the clinical result of modified Bankart operation repairing the Bankart lesion with capsular shifting using suture anchor in traumatic recurrent anterior dislocation of shoulder joint MATERIALS AND METHODS: All of the cases were treated with modified Bankart operation. The inferior and superior capsular flaps were advanced to the anterior aspect of glenoid neck and fixed with three suture anchors in 30 degrees abduction and external rotation of shoulder joint. Especially the inferior 1/3 capsular flap was sutured over the superior 2/3 capsular flap. We used the grading system of Rowe and Zarins as measuring function, pain, stability, range of motion of shoulder joint.
RESULT
The clinical results were excellent in 80%, good in 20%. The mean loss of motion at follow up study was 2% of flexion and 7% of external rotation.
CONCLUSION
This operative technique is useful in repairing the Bankart lesion and gaining adequate capsular tension. And the using of suture anchor could save the operation time.
