Atypical Femoral Fractures: What Do We Know about Them?: Beom Seok Lee, Young Kyun Lee, Heejae Won, Hyungkook Kim, Kyung Hoi Koo; J Korean Fract Soc 2018;31(4):159-164. Published online October 31, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.4.159

Recently, atypical femoral fractures (AFFs) have been found in patients who were prescribed bisphosphonate to prevent osteoporotic fractures. Although the occurrence of AFF is rare, there are some concerns, such as a higher risk of delayed or non-union of AFF. This paper reviews the treatment of AFF and suggests some considerations during surgery.

Sexual Activity at 1 Year after Acetabular Fracture: Chan Ho Park, Young Kyun Lee, Kyung Hoi Koo; J Korean Fract Soc 2017;30(3):111-116. Published online July 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.3.111

Abstract PDF

PURPOSE
Change in sexual activity after acetabular fracture has not been elucidated to date. Hence, the purpose of this study was to reveal: (1) how acetabular fracture affects the status of sexual activity; (2) how acetabular fracture affects patient satisfaction about sexual activity; and (3) what are the concerns of patients regarding sexual activity.
MATERIALS AND METHODS
Between January 2014 and December 2014, a self-reported questionnaire was conducted with patients who had been sexually active before the treatment for acetabular fracture. Out of the nineteen patients who participated in the questionnaire, twelve men and three women were included for final analysis; patients who were treated conservatively were excluded.
RESULTS
All patients had hip pain (mean visual analogue scale score, 2.9; range, 1-7) at 1 year after the trauma. Fourteen patients (93.3%, 14/15) resumed sexual activity within 1 year (mean, 3.9 months; range, 2â€“6 months). After excluding one patient who did not recover to allow sexual activity, the frequency of sex was decreased in 11 patients (78.6%, 11/14). Sexual satisfaction was decreased in seven patients (46.7%, 7/15). Old age was associated with decreased sexual satisfaction.
CONCLUSION
Half of the patients showed a decreased satisfaction from sexual activity after acetabular fracture, with hip pain being the most common problem. Although our study was a small, single-center study, it provides information regarding sexual activity of patients after acetabular fracture.

The Effect of Low Intensity Ultrasound on Distraction Osteogenesis in the Rabbit Femur: Hyung Bin Park, Hae Ryoung Song, Kyung Hoi Koo, Soon Taek Jeong, Bun Jung Kang, Se Hyun Cho; J Korean Soc Fract 2002;15(2):159-165. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.159

Abstract PDF: PURPOSE
The effects of ultrasound on mechanical properties of the callus in distraction osteogenesis was assessed in this study. MATERIAL AND METHOD: Forty mature New Zealand white rabbits were divided into two groups (ultrasound group and control group). A midshaft femoral osteotomy was made and fixed with a small external fixator. After a latent period of a week, lengthening was performed at the rate of 1mm a day for 2 weeks. Low intensity ultrasound (EXOGEN inc, Piscataway, NJ U.S.A) was applied to the operated limb for 20 minutes a day in the ultrasound group, while the control group waited for natural maturation of the callus. The bone mineral density and mechanical properties such as ultimate load, ultimate stress, deflection at ultimate load, ultimate stiffness and energy absorption at ultimate load were measured and analyzed.
RESULT
The bone mineral density, the area of the callus, ultimate load, ultimate stress and energy absorption at ultimate load were not significantly different between the two groups (p>0.05). The ultimate stiffness in the ultrasound group was significantly higher than those of the control group (p<0.01). The deflection at ultimate load in the ultrasound group was significantly lower than those of the control group (p<0.01).
CONCLUSION
The low density ultrasound has a positive effect on the mechanical properties of the distracted callus in the rabbit femoral model in terms of the ultimate stiffness and the deflection at ultimate load.

Triradiate Approach in Surgical Treatment of Complex Fracture of Acetabulum: Kang Il Kim, Kyung Hoi Koo, Bun Joong Kang, Hyung Bin Park, Sun Chul Hwang, Soon Taek Jeong, Hae Ryong Song, Se Hyun Cho; J Korean Soc Fract 2001;14(4):616-622. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.616

Abstract PDF: PURPOSE
To determine the advantages of triradiate approach in complex acetabular fractures, the results were reviewed for 24 patients who had open reduction and internal fixation of complex acetabular fractures with a triradiate approach.
MATERIALS AND METHODS
Twenty four patients were followed for a mean of 3 years after the operation. All patients with complex fractures of the acetabulum were treated with open reduction and internal fixation using Y-shaped triradiate incision, osteotomy of the greater trochanter, and arthrotomy of the hip joint. In 13 patients the fracture was fixed with reconstruction plates and in I 1 patients the fracture was fixed with the plates and wires.
RESULTS
All fractures united and no patient required subsequent total hip replacement arthroplasty. Four patients had heterotopic ossification without serious limitation of motion of the hip and one patient had grade IV lesion as defined by Brooker et al, which limited motion of the hip enough to impair function. Six patients showed posttraumatic arthritis at the latest radiograph. The overall clinical result was excellent for 7 hips, good for 13, and fair for 4 as defined by d' Aubigne and Postel. The radiological result was excellent for 13 hips, and good for 6 as defined by Matta. One femoral head necrosis was observed at the latest follow-up.
CONCLUSION
A triradiate approach provides a good extra and intraarticular access to complex fracture of the acetabulum, which facilitates an accurate reduction, rigid fixation, removal of loose osteochondral fragments and management of labial injury, without increased morbidity of the hip joint.
