Abstract PDF: A 35-year-old woman visited the emergency department for a pedestrian traffic accident. Severe tenderness was noted at the posterior sacrum area, without open wound or initial neurologic deficit. Fracture of the left sacral ala extended to the S1 foramen, anterior acetabulum, and pubic ramus. Two weeks after the injury, she presented aggravating radiculopathy with the weakness of the left great toe plantar flexion. The S1 nerve root was compressed by the fracture fragments in the left S1 foramen. Decompressive S1 foraminotomy was performed. The postoperative follow-up computed tomography scan showed successful decompression of the encroachment, and the patient recovered well from the radiculopathy with motor weakness. She was able to resume her daily routine activity. We suggest that early decompressive sacral foraminotomy could be a useful additional procedure in selective sacral zone II fractures that are accompanied by radiculopathy with a motor deficit.

Usefulness of the Cementless Stem for the Treatment of Hip Fracture in Elderly Patients with Osteoporosis: Comparative Analysis between Cementless Stem and Cemented Stem: Joon Soon Kang, Kyoung Ho Moon, Rhu Seop Kim, Sang Ho Lee, Jong Min Choi; J Korean Fract Soc 2011;24(1):16-22. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.16

Abstract PDF: PURPOSE
We evaluated the usefulness of the cementless stem in treating hip fracture patients older than 70.
MATERIALS AND METHODS
We studied elderly osteoporotic hip fractures in the neck and intertrochanter area who had received hip arthroplasty with over 2 years of follow up period. Among those, we analyzed the clinical and radiological results of hip arthroplasty with cemented stem (group 1) and hip arthroplasty with cementless stem (group 2). Each group was consists of fifty hips.
RESULTS
The mean age at surgery was 75 years and mean follow-up period was 40 months (minimum 24 months). The admission period was 28.68+/-8.8 days for group 1 and 28.05+/-8.7 days for group 2 (p>0.05) and the average operation time was 87+/-21.2 minutes, and 80+/-17 minutes (p>0.05) and the total blood loss was 611+/-141.3 cc and 557+/-120.5 cc (p>0.05) respectively. There was no statistically significant difference in all aspects. One case of pulmonary embolism occurred in group 1. Stem loosening was not observed in both groups at the last follow-up radiologic study.
CONCLUSION
The hip arthroplasty with cementless stem for the osteoporotic hip fractures showed a competent results clinically and radiologically in short term follow up as compared with the cemented stem.

Treatment of Humeral Shaft Fracture with AO Unreamed Humeral Nail: In Heon Park, Kee Byoung Lee, Kyung won song, Jin Young Lee, Min Choi; J Korean Soc Fract 1999;12(2):429-434. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.429

Abstract PDF: We performed a retrospective study of nine humeral shaft fractures which were treated by interlocking intramedullary nailing, the AO UHN (Unreamed Humeral Nail) system between March 1996 and February 1997 with more than one year of follow up. AO UHN inserted by either antegrade or retrograde technics through limited incisions followed by insertion of 2 proximal and distal Interlocking screws. Compression between fractured fragments was achieved in the non-comminuted and indicated cases. Immediate postoperately, soft shoulder immobilizer was applied and rehabilitation was started with active shoulder motion exercise few days to 1 week postoperately as soon as patient could tolerate pain. Union occurred at average of 13 weeks except one expired case with pathologic fracture due to advanced metastatic cancer. Pain relief and functional restoration were rated as good to excellent in most cases. Interlocking intramedullary nailing using AO UHN for the humeral shaft fractures usually provides immediate stability of the fracture and can be accomplished with a closed technique, minimum morbidity, with a resultant early return of function of the extremity. Therefore we recommend AO UHN for the treatment of the humeral shaft fractures if available without hesitation.
