Principles for Management of Periprosthetic Acetabular Fractures after Hip Arthroplasty: Chan Woo Park, Hyoung Keun Oh, Woo Suk Lee, Youn Soo Park, Seung Jae Lim; J Korean Fract Soc 2019;32(3):148-156. Published online July 31, 2019; DOI: https://doi.org/10.12671/jkfs.2019.32.3.148

Periprosthetic acetabular fracture (PAF) is an uncommon complication following hip arthroplasty. However, as the number of people needing hip prostheses continues to rise, the absolute number of PAF is expected to increase as well. These fractures may occur either intraoperatively or postoperatively. Postoperative fractures can be caused by traumatic events or by pathologic conditions related to periacetabular osteolysis. The management of PAF usually depends on the degree of displacement and the stability of the acetabular component. While most of non-displaced fractures can be managed nonoperatively by protected weight bearing, displaced fractures with unstable implants require surgical intervention, which is often technically challenging. This review summarized the latest findings on the epidemiology, the diagnosis, the classification, and the treatment of PAF.

Treatment of Femoral Shaft Nonunions with Dynamic Compression using Interlocking-Compression (IC) Nail: Youn Soo Park, Young Wan Moon, Ki Sun Sung; J Korean Soc Fract 2003;16(2):155-162. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.155

Abstract PDF: PURPOSE
To evaluate the effectiveness of a specially designed Interlocking-Compression Nail (IC Nail(R), Osteo, Switzerland) which allows compression force across the nonunion site for the treatment of femoral shaft nonunions.
MATERIALS AND METHODS
Between Nov. 1998 and June 2002, twenty one nonunions of femoral shaft fractures in twenty patients were treated with reamed IC nails of larger diameters without bone grafting in 9 men and 11 women, 8 to 45 months after initial operations. Seventeen cases were hypervascular nonunions, 3 avascular, and 1 infected. For initial operation, 10 closed nailing, 10 open nailing and 1 plate fixation were performed. One or more additional procedures had been done in 17 cases prior to IC nailing.
RESULTS
The nonunion gap was considerably narrowed from 7.4 mm to 3.1 mm with IC nailing and bony unions were achieved in all but one case. The time for radiographic union was 4 to 15 months posteoperatively with an average of 7.4.
CONCLUSION
Reamed IC Nail(R) with a larger diameter is an effective procedure for femoral shaft fracture nonunion regardless of initial treatment modalities and even in 3 avascular nonunions, 2 have shown radiographic union without bone grafting. Additional procedures are to be considered in failed surgery of avascular nonunions.

Effect of Trochanter Stabilizing Plate in Unstable Intertrochanteric Fracture: Youn Soo Park, Kye Young Han, Hyung Gun Kim; J Korean Soc Fract 2000;13(4):779-787. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.779

Abstract PDF

PURPOSE
The purpose of this study is to investigate the effectiveness of trochanter stabilizing plate (TSP) with compression hip screw(CHS) on the reduction stability, fracture union and sliding of lag screw in unstable intertrochanteric fracture. MATERIAL AND METHOD: From October 1997 to March 1999, 32 cases(group 1) and 20 cases(group 2) who could be followed for more than 1 year were treated with TSP (group 2) and CHS only (group 1) due to unstable intertrochanteric fractures. And two groups were compared clinically and radiologically.
RESULTS
Operation time was longer in group 2 and hospital stay was longer in group 1. Preoperative functions were better in group 1(7.00 points) than in group 2(6.47 points). When postop. function was compared with preop. function, group 1 showed differences on the three months follow-up and six months follow-up. Whereas group 2 only showed difference on the three months follow-up but not on the six months follow-up. There was no difference in the incidence of lag screw sliding. However, there were differences in the extent of sliding between group 1(ave.4.88mm) and group 2(ave.2.88mm) with three months follow-up and six months follow-up (group 1: ave 5.42mm and group 2: ave. 3.03mm). There was a significant difference between group 1(12cases) and group 2(0 case) in greater trochanter lateralization, but shaft medialization between group 1(17cases) and group 2(10cases) showed no difference. Loss of neck-shaft angles between group 1(9cases) and group 2(3cases) were not significantly different. Due to loss of reduction, one case in group 1 was reoperated.
CONCLUSION
Application of TSP is not a difficult procedure and reduce excessive sliding of lag screw. And early fuctional recovery without adverse effect of bone healing is possible. So in unstable intertrochanteric fracture, additional use of TSP is effective.

Intra-articular Fracture of the Calcaneus: Analysis of Result of Operative Treatment and Prognostic Factor: Sung Soo Chung, Jai Gon Seo, Youn Soo Park, Chong Suh Lee, Tae Kyu Hwang; J Korean Soc Fract 1998;11(4):865-872. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.865

Abstract PDF: The calcaneus is the most commonly fractured tarsal bone, but the appropriate care of calcaneal fracture continue to be an unsolved dilemma. As technology in imaging has improved, operative treatment is more suggested. The purpose of this study is to evaluate the results of operative treatment in intra-articular calcaneal frcture and to analyse the results in accordance with various prognostic factors. We analysed retrospectively 13 patients, 17 intra-articular calcaneal fractures undergone operative treatment. Mean follow-up period was 27 months (range:13 ~ 44 months). There were 11 males and 2 females with 41 year old mean age (range:18 ~ 63 years old). Clinical assessment used the modified Creighton-Nebraska health foundation assessment sheet for fracture of the calcaneus. We obtained excellent result in 7 cases (41.2%), good in 2 cases (11.8%), fair in 7 cases (41.2%) and poor in 1 case (5.8%). Clinically age and body weight, radiologically Bohler angle, fibulo-calcaneal distance and subtalar joint discrepancy are related to the prognosis of intra-articular calcaneal fracture following operative treatment. Postoperative complications are limping (2 case), heel pain (3 cases), hump bump of calcaneus (1 case) and subtalar arthritis (1case). In conclusion, on the basis of our results, there is a relationship between anatomical abnormalities of the heel and a poor clinical outcome. Therefore, in operative treatment of intra-articular fracture of calcaneus, we recommend anatomical reduction, if possible, not only of the subtalar joint but also of the Bohler angle and fibulo-calcaneal distance.
