The Usefulness of Low-Intensity Ultrasound for Nonunion and Delayed Union: Yeo Heon Yun, Jong Oh Kim, Young Do Ko, Jae Doo Yoo, Jun Mo Jung, Jong Gun Oh, Han Chen Bang, Chang Ho Choi, Myeung cheol Shin; J Korean Soc Fract 2003;16(1):104-111. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.104

Abstract PDF: PURPOSE
To evaluation of usefulness of low-intensity ultrasound for nonunion and delayed union.
MATERIALS AND METHODS
For 5 months, we treated 7 delayed union and 8 nonunion using low-intensity ultrasound. After 5 months, in checked X-ray AP and Lateral view, when cortical bridge formation was done, we through union.
RESULTS
In 7 delayed union, 5 cases-2 femur, tibia, humerus, radius were healed. In 8 nonunion, 3 femur nonunion were healed. Union rate was 71% in delayed union 37.5% in nonunion.
CONCLUSION
we thought that the low-intensity ultrasound has capacity of induction of union and was considered as the method of treatment for delayed union.

The Prefracture Factors on The Hip Fracture in Elderly: Jong Oh Kim, Yeo Hon Yoen, Young Do Ko, Jae Doo Yoo, Jun Mo Chung, Han Cheon Bang, Kyu Bok Kang; J Korean Soc Fract 2002;15(4):531-537. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.531

PURPOSE
We studied the co-relation on the causes of the hip fracture through the analysis of a relevance on the etiological factors as increased incidence according increasing old ages.
MATERIALS AND METHODS
Total 158 cases that treated on the hip fracture from 2001 Jan. to 2002 May were studied. The parameters were age, gender, smoking, obesity, type of fracture, place of fracture, other comorbidity, activity of daily living, bone marrow densitometry, hardness of floor, orientation, injury energy. And then, we analysis of difference between femur neck fracture and femur intretrochanter fracture and between stable femur intertrochanter fracture and unstable femur intertrochanter fracture.
RESULTS
The incidence of the femoral intertrochanteric fracture was larger significantly than that of the femoral neck fracture in the older than 80(p < 0.001). On the comparison of the pre-fractural activity of daily living, the group revealed lower activity had larger incidence of femoral intertrochateric fracture(p < 0.001). Also, the femoral intertrochanteric fracture was more larger in osteoporosis patient group(p < 0.005), and lower energy trauma(P<0.05). In a unstable femoral intertrochanteric fracture, 21 cases(77.7%) of total 27 cases were belong to the group of the activity of daily living scale below C(p < 0.05), 24 cases of 27 cases were belong to the osteoporosis patient who was estimated below -3.0 on T-score(p < 0.001).
CONCLUSION
In the hip fracture of the elderly patients, the femoral intertrochanteric fracture is more prevalance rather than the femoral neck fracture on the cases of older patient more than 80 year-old, lower activity of daily living scale, lower T-score less than -3.0 on BMD, lower energy trauma. Also, in femur intertrochanter fracture, unstable fracture is more common in low daily activity and osteoporosis

Treatment of Humeral Shaft Nonunion after Primary Internal Fixation: Jong Oh Kim, Yeo Hon Yun, Dong Wook Kim, Young Do Ko, Jae Doo Yoo, Jin Won Jung; J Korean Soc Fract 2001;14(2):236-244. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.236

Abstract PDF: PURPOSE
To evaluate the methods of treatment to obtain rigid fixation for nonunion of humerus shaft fractures developed after operative treatment.
MATERIALS AND METHODS
From January 1993 to January 2000, twenty-one patients of nonunion of humerus shaft after primary internal fixation were reviewed and the results were analyzed. Three cases who have loss of follow-up were excluded.
RESULTS
In twenty-one cases, nineteen had union but, two cases have failed. In the group of compression plate fixation and bone graft, bone union was completed at mean 4.4 months, in the group of IM nailing and bone graft at 4.9 months, in case of bone graft only with state of IM nailing at 5.5 months. Mean time until bone union was 4.6 months.
CONCLUSION
Distraction should be avoided during IM nailing at primary internal fixation. Secondly, To obtain rigid fixation in nonunion of humerus shaft after primary internal fixation, use larger and more broad plate, dual plate or IM nail.
