Factors Affecting the Functional Result of Monteggia Fractures in Adults: Yong Bum Park, Byeong Ki Lee, Kwang Won Lee, Whoan Jeang Kim, Ha Yong Kim, Jae Hoon Ahn, Won Sik Choy; J Korean Soc Fract 2000;13(3):597-604. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.597

PURPOSE
Monteggia fracture is a combination of ulnar fracture and radial head dislocation. Despite of low incidence, Monteggia fracture has a problem in the treatment. So satisfactory results could not be achieved easily. The purpose of this study was to analyze factors affecting functional results in Monteggia fracture.
MATERIALS AND METHODS
From January 1990 to June 1998, we retrospectively reviewed 24 patients out of 40 patients who had been treated for Monteggia fracture. The functional assessment was performed with Broberg and Morrey system10).
RESULTS
Excellent and good results were achieved in 16 cases(66.6%), whereas fair and poor results in 8 cases(33.4%). Satisfactory results were obtained in 66.6% overall. According to the Bado classification, functional results were not different significantly between types. According to the mechanisms of injury, unsatisfactory results were obtained in 8 of 17 patients with high energy injury. Monteggia fractures with ulnar fracture at the diaphyseal level showed satisfactory results significantly compared to others. In terms of the methods of internal fixation, the plate and screw fixation showed satisfactory results in 14 of 16 patients whereas tension band wiring or intramedullary nailing showed unsatisfactory results in 6 of 8 patients.
CONCLUSION
In Monteggia fractures, factors affecting functional result may be the mechanism of injury, the level of ulnar fracture and the method of internal fixation.

Published online April 30, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.2.414

Abstract PDF: PURPOSE
: This study was performed to compare the functional results according to the methods of internal fixation in olecranon fracture-dislocation.
MATERIALS AND METHODS
: Authors retrospectively analyzed in 13 adult patients with olecranon fracture-dislocation (Colton II D) who were treated by internal fixation from January 1991 to June 1998. Functional results were assessed by Broberg and Morrey system and radiographic results were analyzed in terms of articular step-off, articular gap and reduction loss.
RESULTS
: In regard to functional assessment, all oblique fractures treated with plate and screw showed 100% of satisfactory result whereas those treated with tension bands showed 33.4% of satisfactory result. Comminuted fractures treated with plate and screw showed 40% of satisfactory result whereas all two treated with tesion bands resulted in unsatisfactory result. In regard to radiologic assessment, three oblique fractures treated with plate and screw result whereas those treated with tension bands resulted in fair result. Comminuted fractures treated with plate and screw resulted in three fair, two poor radiologic results whereas those treated with tension bands resulted in one fair, one poor result.
CONCLUSION
: Plate and screw fixation can obtain more satisfactory functional and radiologic results than tension bands in oblique and comminuted olecranon fracture-dislocation

Treatment of Humeral Shaft Nonunion after Primary Internal Fixat: Kwang Won Lee, Kyou Hyeun Kim, Whoan Jeang Kim, Ha Yong Kim, Jae Hoon Ahn, Yong Bum Park, Won Sik Choy; J Korean Soc Fract 1999;12(3):704-711. Published online July 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.3.704

Abstract PDF: We retrospectively reviewed one hundred fifty-two patients who were treated for humeral shaft fractures at Eul-Ji Medical College hospital from Jan 1991 to June 1997. We experienced twenty one cases of nonunion among them after primary internal fixation. The purpose of this study was to evaluate possible causes of nonunion and to find out adequate treatments. The main cause of nonunion was an inadequate fixation (57%). The most common fracture pattern was simple transverse type(22%), and it occurred most frequently at the middle one third area of humeral shaft(22%). For the treatment of nonunion, the plate fixation was done in ten cases, interlocking intramedullary nailing in three cases, bone graft only in six cases, and external fixation using monofixator(Orthofix) in two cases. We obtained complete bony union from all cases, and the average union time was 17.5 weeks. Our study showed that higher incidence of nonunion was found in primary intramedullary nailing cases(19%) than in primary plate fixation cases(4%). In conclusion, close attention should be paid when choose the primary fixation method, and plate fixation and bone graft was considered as one of the useful treatment method of nonunion.

Treatment of Ipsilateral Femur and Tibia Fractures: Yong Bum Park, sang Ho Moon, Chung Su Hwang, Soon Hyun; J Korean Soc Fract 1998;11(4):754-760. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.754

Abstract PDF

Ipsilateral femur and tibia fractures - so called "floating knee" are caused by high energy trauma and frequently associated with many problems such as hemorrhagic shock, higher morbidity, delayed union, knee stiffness, etc. To get a satisfactory functional result, rigid internal fixation and early mobilization are regarded as treatment priciples at present. Authors analyzed the functional outcomes of floatinhg knee injuries according to the fracture type and methods of surgical treatments. Twenty-eight patients were diagnosed as ipsilateral femur and tibia shaft fractures and treated surgically at the Dongguk University Hospital between June 1990 and May 1996. Average age was 34.5 years, and males were predominant. Majority of cases (27 out of 28) were caused by traffic accident. According to the classification of Blake and McBryde, type I injuries were observed in 17 cases and type II in 11 cases. Average follow up period was 1.3 years. All patients were treated by surgical methods which were selected appropriately with concideration of fracture types. 14 of 17 type I injuries were treated with intramedullary nailing for both femur and tibia fractures. Among these cases, 9 were excellent and 4 were good results. But in type II injuries, only 3 of 4 cases which were fixed with intramedullary nailing for femur and plate for tibia fractures were good results. Conclusively, Intramedullar nailing is an excellent method for ipsilateral femur and tibia fracture and type II injuries which have intra-articular fracture lines meet with worse results than type I.

Treatments of Tibial Condylar Fractures: Yong Bum Park, Chung Soo Hwang, Phil Hyun Chung, Suk Kang, Dong Ju Chae, Han Chul Kim, Sang ho Moon, Seung Hun Lee, Tae Young Kim, Sun Hyun Yun; J Korean Soc Fract 1998;11(4):790-797. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.790

Abstract PDF: The tibial condylar fractures are characterized by intra-articular extension of fracture line and associated soft tissue injuries, and could affect knee alignment, stability, adn range of motion after treatments. Therefore, anatomical reduction and rigid internal fixation is mandatory to get satisfactory results. But this method of treatment can not be always possible due to technical dimend of surgical sklls and high risk of postoperative infection. The authors analyzed 43 cases of tibial condylar fractures, which were treated at the orthopaedic department of the Dongguk University Hospital from March 1990 to May 1996. Males were 34, and females were 9. Average age of patients was 41.4 years, and average follow up period was 18 months. The most common causes of injuries were traffic accidents (36 cases), and most common type of fracture was Schatzker type I. associated soft tissue injuries were observed in 21 cases. Treatment methods were chosen by degree of displacement of fracture fragment and associated soft tissue injuries. Conservative treatments were done in 23 cases and operative treatments in 20 cases. Satisfactory results were obtained in overall 32 cases(74%) regardless of the methods of treatment. Unsatisfactory results were observed in patients who had associated soft injuries and significant displacement of fracture. Conclusively, satisfactory results could be obtained in patients with tibial condylar fractures by appropriate selection of treatments according to displacement of fracture and associated soft tissue injuries.

Treatments of the delayed Union or Nonunion of Tibial Shaft Fracture Fixed with Interlocking IM nail: Yong Bum Park, chung Soo Hwang, Phil Hyun Chung, Suk Kang, Dong Joo Chae, Han Chul Kim, Sang Ho Moon, Jong Phil Kim, Dae Jin Kim; J Korean Soc Fract 1998;11(3):552-559. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.552

Abstract PDF: Interlocking intramedullary nailing has been the first choice treatment of most tibial shaft fractures because its rigidity of fixation allows early ROM and weight bearing. Although most interlocking nailing procedures are performed with closed reduction that preserve periosteal blood supply, delayed union or nonunion is often occurs. so secondary procedures, such as bone graft, dynamization, nail exchange, are necessary to achieve fracture healing. We analyzed 25 cases of delayed union or nonunion from 432 tibial shaft fractures fixed initially with static interlocking intramedullary nailing since January 1990 till January 1996. Overall incidence of delayed union or nonunion is 5.8%(25/432). Secondary procedures included mainly iliac bone graft or dynamization. Average time to achieve bone union after secondary procedure is 6.1 months. The more distracted or displaced fracture ends after interlocking nailing or the more comminuted fracture fragments led to the more delayed bone union. Careful attention to minimize distraction or displacement during interlocking nailing is necesary to decrease the incidence of delayed union or nonunion. And appropriate procedures should be performed when delayed union or nonunion is predicted, which result in success in most cases.

The Gamma Mail for Subtrochanteric Fractures of the Femur: Suk Kang, Jung Soo Hwang, Phil Hyun Chung, Dong Ju Chae, Yong Bum Park, Han Chul Kim, Kyu Hwang Um, Jeong Yong Hong; J Korean Soc Fract 1998;11(1):159-167. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.159

Abstract PDF: The aubtrochanteric area is cortical bone which has a decreased blood supply and a serious communition after trauma. Large biomechanical stresses in the subtrochanteric area can lead to failure of fixation devices. Many fixation devices have been used to treat the fractures of subtochanter of the femur. The Gamma nail was introduced for the treatment of peritrochanteric fractures with the theoretical advantage of a load-shearing femoral component. We reviewed 15 patients of subtrochanteric fractures who were treated by use of the Gamma nail at Dongguk university hospital since March 1993. Results showed satisfactory fracture union with little loss of position, even in comminuted fractures. The patients had shorter convalescence and earlier weight bearing. Perioperative complications were few. We conclude that Gamma nail is effective in achieving good stabilization of the unstable fractures of the subtrochanteric region and is an advance in the treatment of subtrochanteric fractures of the femur.
