Treatment of the Intertrochanteric Fractures of the Femur in Elderly Patients: Comparision of Wayne-County Reduction and Anatomical Reduction: Nam Yong Choi, Kee Ho Nah, Hyun Seok Song, Sang Il Seo, Jung Keun Choi, Suk Ku Han; J Korean Fract Soc 2004;17(4):301-307. Published online October 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.4.301

Abstract PDF

PURPOSE
To compare the radiological and clinical results of Wayne-County reduction with anatomical reduction in treatment of the intertrochanteric fractures of the femur in elderly patients.
MATERIALS AND METHODS
Among one hundred-three of intertrochanteric fractures treated with 135- degree angled compression hip scresw, eighty three cases treated by Wayne-County reduction (Group 1, 42 cases) and anatomical reduction (Group 2, 41 cases) with at least 1 year follow-up were reviewed. The average pateint ages were 72.4 (65~92) in group 1, 71.6 (65~89) in group 2, respectively. 33 cases (75.2%) in group 1 and 31 cases (77.5%) displayed unstable fractures by Jensen classification. The radiological observation was included neck-shaft angle, penetrating length of lag screw into head, sliding length of lag screw and time of bony union. The clinical results were evaluated by Koval criteria, Kyle's functional evaluation, leg length inequality and complications.
RESULTS
There were no significant changes between group 1 and group 2 in stable fractures in the radiological and clinical results. In unstable fractures, the neck-shaft angle averaged 132.2 degree in group 1 and 129.4 degree in group 2 in the final follow-up films. The penetrating length of lag screw into head were 2.2 mm in group 1 and 3.1 mm in group 2 (p<005). But there were little differences in the sliding length of lag screw, the time of bony union and complication rates between groups. In post- operative evaluation of walking abilility by Koval, 31 patients (73.8%) in group 1 and 28 (68.3%) recovered the activity level before injury by the postoperative 1 year follow-up. Leg length discrepancy at final follow-up was 4.1+/-6 mm shortening in group 1 and 6.5+/-8 mm in group 2, respectively.
CONCLUSION
Both Wayne-County reduction and anatomical reduction had a favorable results after treatment of stable intertrochanteric fractures of the femur, but Wayne-County reduction may be a better method in treatment of unstable fractures, especially in elderly patients, in which it is difficult to obtain anatomical reduction.

Avulsion Fracture of Calcaneus in Diabetic Patients: Sung Jin Park, Nam Yong Choi, In Tak Chu, Suk Ku Han, Ki Ho Nah, Hyun Seok Song, Jung Ho Kim; J Korean Fract Soc 2004;17(2):173-176. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.173

Abstract PDF

Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed fracture healing in most cases, but skeletal deformity may develop in some cases. Therefore we should do plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

Treatment of Infected Nonunion of Long Bone Shaft: Comparison between Fixation by Antibiotic-cement Loaded Intramedullary Nailing and Fixation by Antibiotic-cement Loaded External Monofixator: Ki Ho Nah, Seong Jin Park, Suk Ku Han, Hyun Suk Song, Nam Yong Choi; J Korean Soc Fract 2003;16(4):511-518. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.511

Abstract PDF: PURPOSE
To evaluate the surgical results between fixations by antibiotic-cement loaded intramedullary nailing and antibiotic-cement loaded external monofixator in the treatment of infected nonunion of long bone shaft with mild bone loss and shortening of less than 1 cm.
MATERIALS AND METHODS
Among the 15 cases of infected nonunion of long bone shaft, 6 cases treated with fixation by antibiotic-cement coated intramedullary nailing and 3 cases treated with fixation by intramedullary nailing along with antibiotic-cement beads insertion were divided as group I (n=9), and other 6 cases treated with fixation by external monofixator along with antibiotic-cement beads insertion were divided as group II (n=6). There was no difference between the two groups in the degree of infection in the laboratory data and clinical feature and degree of bone loss and shortening. Male was in 7 and 5 patients, average age of the patients was 34.8 (26~53) and 37.2 (20~63) years old and average follow-up period was 15.9 (12~35) and 19.3 (15~41) months in group I and II respectively.
RESULTS
Among the nine cases of group I, 3 cases were newly convereted into fixation by antibiotic-cement coated intramedullary nailing at average 9.5 weeks. Radiologic union was gained at the average of 26 weeks from the time of initial nail fixation. Infection was responsive at 6.1 weeks by laboratoey data. Knee ROM of more than 100 degrees was gained in all case and average shortening was 9.2 mm in the last follow-up. And external rotation deformity of more than 5 degrees was noted in 1 case. Among the six cases of group II, radiologic union was gained at 14 weeks in 1 case without converting to internal fixation, and the other 5 cases were converted to antibiotic cement loaded intramedullary nailing at average 12.5 weeks because of delayed uinon or angulation deformity, and radiologic union was gained at average 44 weeks from the time of fixation by external fixator. Infection was responsive at 10.2 weeks by laboratoey data. Knee ROM of more than 100degrees was gained in 5 cases, and average shortening was 11.8 mm in the last follow-up.
CONCLUSION
In the treatment of infected nonunion of long bone shaft with mild bone loss and shortening of less than 1 cm, the fixation by intramedullary nailing with the use of antibiotic-cement prefers to the fixation by external monofixator with the use of antibiotic-cement in the velocity of union, control of infection, and in the clinical aspects such as alignment, early ambulation and joint stiffness.

Abstract PDF: PURPOSE
To evaluate the radiological and clinical results of the treatment of distal clavicular fractures with coracoclavicular ligament injury by coracoclavicular fixation with plating or repair of coracoclavicular ligament.
MATERIALS AND METHODS
Sixteen cases with minimum six months of follow-up were included in our study. Male was twelve and average age was 43(28-80). Ten cases of Craig type 2 were treated with coracoclavicular screw fixation with plating. Six cases of Craig type 5 were treated with coracoclavicular screw fixation with repair of coracoclavicular ligament. The radiologic assessment including coracoclavicular distance and union time and the clinical assessment including range of motion and degree of pain were evaluated.
RESULTS
Fifteen cases were united, but one case developed osteomyelitis and nonunion. Full range of motion was achieved in fifteen cases at last follow-up. Average coraco- clavicular distance compared to contralateral site in AP view was 2.1 mm increase in patients with plate fixation and 1.3 mm increase in patients with ligament repair. Average union time was 14.3 weeks and little differenece was noted between two groups(P>0.05).
CONCLUSION
Coracoclavicular screw fixation with plating or repair of coracoclavicular ligament were a useful method to treat distal clavicular fractures combined with coracoclavicular ligament injury.

Morbidity and Mortality of Bilateral Hip Fractures in Elderly Patients: Suk Ku Han, Nam Yong Choi, Seong Jin Park, Seong Keun Lee, Chan Woong Moon; J Korean Soc Fract 2000;13(4):788-794. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.788

Abstract PDF

PURPOSE
The purpose of this study was to estimate the morbidity and mortality rate of bilateral hip fractures in elderly patients compared to that in unilateral hip fractures and to evaluate it's related risk factors.
MATERIALS AND METHODS
Twenty-two cases of bilateral hip fractures in patients who were older than 70 years with at least two year follow-up were included in our study. We analysed the risk factors of bilateral hip fractures by comparing with age, sex and diagnosis matched 22 cases of ipsilateral hip fractures including onset of secondary fracture, injury mechanism and the rate of morbidity and mortality, respectively.
RESULTS
The onset of secondary fracture and death were mostly within 1 year after operation for the first hip fracture. Comorbidity of cardiovascular, neurologic, urologic or history of previous fracture and decreased ambulation ability were related with the occurrence of bilateral hip fractures. The rate of morbidity and mortality of bilateral hip fractures were about two- fold than that of ipsilateral hip fractures. High mortality rate was noted in patients who had operation delay from injury. But no significant relationship between nutrition, body weight or bone mineral density and the development of secondary hip fractures.
CONCLUSION
To prevent the occurence of bilateral hip fractures which had more serious results than that of ipsilateral hip fractures, more aggressive rehabilitation to improve walking ability and appropriate environmental circumstances to avoid falls were important, especially in older patients.

Treatment of Open Fractures of the Tibial Shaft by Sequential Compression technique in Ilizarov device: Suk Ku Han, In Ju Lee, Nam Yong Choi, Sung Jin Park, Gyeol Yoo, Hyo Seng Ahn; J Korean Soc Fract 1998;11(4):817-824. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.817

Abstract PDF: External skeletal fixation is used widely in the management of open or closed tibial fractures, but delayed healing is common. There is concern that this might be due not only due to the severity of injury but also to the mechanical conditions imposed at the fracture site by the fixator. Since fractures treated by external skeletal fixation can rarely be reduced to perception nor held with absolute stability, union occurs by indirect healing, which is acutely sensitive to both the charactericstics and timing of mechanical stimulation. So, the achivevment of the optimum mechanical environment is particularly important where delay in bone healing is likely. Ilizarov external fixator is useful in treating open fractures of the tibial shaft because it permits axial micromotion which enhances bridging callus formation with stable fixation as well as its complications such as infected nonunion or limb length discrepancy. The impared healing with external fixation is often caused by wrong surgical technique, such as distraction of fracture fragments by fixation device. Sequential compression at fracture site may overcome any fracture gap in external skeletal fixation and also enhance endosteal bone formation. We applied sequential compression forces at the fracture site in 18 open fractures of the tibial shaft, trated by Ilizarov external fixator with or without autogenous bone grafting. Sequential compression technique is composed of initial compression with 1 mm/wk for 4 weeks and then compression 1 mm/10 days until adequate apposition of cortex and callus formation in radiograph. We acquired successful bony union in all cases except one which had additional bone grafting in open fractures of the tibial shaft by sequential compression technique using Ilizarov device.

The Acute surgical Treatment in Superior Peroneal Retinacular Injury in Ankle: Suk Goo Han, Nam Yong Choi, In Tak Choo, Sung Jin Park, Young Mok Kang, In Ju Lee; J Korean Soc Fract 1998;11(3):605-610. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.605

Abstract PDF: The superior peroneal retinacular injury in ankle is often diagnosed as an ankle sprain and treated conservatively because of normal bony contour in type 1,2 injury according to Eckery's classification and small bony fragment with early union, evenly displaced in type 3. But its complications such as peroneal tendinitis and recurrent subluxation or dislocation of peroneal tendons sometimes develop late. Compared to peroneal tendinitis, the surgical treatment method for recurrent subluxation or dislocation of peroneal tendons is known superor to conservative method in results. And many reconstructive methods have been reported. In spite of their good results, harmfulness to normal structures, recurrences and technical difficulties may be a problem. So we perfomed 10 cases of acute surgical repair in superior peroneal retinacular injuries in ankle from March 1993 to February 1997 and prospectively analysed their clinical and radiological results with complications. Preoperative radiological diagnosis was done by plain films, peroneal tenography with computed tomography and also postperatively evaluated with plain films and peroneal tenography. 1. The most common cause of injury was sports(6 cases) including ski injury(4 cases) and average age of the patient was 29(17-56) years. 2. 4 cases of bony avulsion(type 3) were fixed with mini-screws and mean duration of bony union was 3.6 months. 3. The incidental subluxation or dislocation of peroneal tendons was not found intraoperatively and postoperatively. 4. All patients are able to participate in active exercise postoperatively except one patient who complains of lateral ankle discomfort due to peroneal tendinitis. In conclusion, acute surgical repair of superior peroneal retinacular injury in ankle is a recommended method to prevent it's complications such as peroneal retinacular injury in ankle is a recommended method to prevent it's complications such as peroneal tendinitis and subluxation or dislocation of peroneal tendons especially, in young and active patients.

Surgical Treatment of Stenosing Synovitis and Dislocation of Peroneal Tendon as a Complication of Calcaneal Fracture: Seong Jin Park, Suk Whan Song, Nam Yong Choi, Byung Lae Jo, In Ju Lee; J Korean Soc Fract 1997;10(1):99-103. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.99

Abstract PDF: Malunion of calcaneal fracture results in most of long-term complications such as pain and limitation of motion at hindfoot. Though it is reported that patients symptoms continue to improve during following years, some patients are disabled espicially due to pain. Among the source of pain following malunited calcaneal fracture, traumatic arthritis of subtalar joint, peroneal tendinitis with or without dislocation of tendons, compression neuropathy, and other sequelae were believed to be responsible. The authors report the result of surgical treatment of 9 patients with malunited calcaneal fracture, who had stenosing tenosynovitis(3 cases), and recurrent dislocation of peroneal tendon(6cases). key words; peroneal tendon, stenosing tendinitis, dislocation, malunion, calcaneus Excision of bone mass from the lateral wall of calcaneus and adhesiolysis relieved symptoms of stenosing synovitis. Zoellner and Clancy technique of deepening peroneal tendon groove and reconstruction of peroneal retinaculum using periosteal flap were supplemented for dislocation of peroneal tendon. Among nine patients, four needed subtalar arthrodesis. The results were favorable.

K-wire Migration into the Thoracic Cavity after Surgery of Scapular Fracture: A Case Report: In Ju Lee, Nam Yong Choi, Young Chae Lee, Hyun Seok Song; J Korean Soc Fract 1996;9(2):326-329. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.326

Abstract PDF: The use of smooth and threaded pins for internal fixation is often complicated by component migration to a part of the body especially when employed about the acromioclavicuiar Joint. A case report of K-wire migration into the thoracic cavity following surgery of scapular fracture is presented. This phoenomenon occurred despite efforts to bend the lateral ends of the pins to prevent medial migration. If pins or wires are employed even bent at the lateral ends, chinidcal and x-ray follow up should be frequent. The pins should be removed immediately on obtaining the desired therapy.

Problems in the use of Compression Hip Screw in the Treatment of Hip Fractures: Myung Sang Moon, In Ju Lee, Nam Yong Choi, Dong Soo Choi; J Korean Soc Fract 1990;3(1):96-102. Published online May 31, 1990; DOI: https://doi.org/10.12671/jksf.1990.3.1.96

Abstract PDF: Though compression hip screw system has many advantages over the other fixation devices in the treatment of hip fractures, surgeons were frequently encountered by the intraoperative and postoperative complications leading to poor result. In reviewing out series of hip fractures treated with this device, between January 1983 and December 1988, serious complications developed in 5 cases, Additionally, three cases who were referred to our hospital during the same period were included in this study. The authors analyzed these 8cases, and found that the complications could have been prevented in using compression hip screw system for the treatment of hip fractures. The purpose of this paper is to re-emphasize the importance of 1) strict application of indication, 2) familiarity with surgical technique and handing instruments, 3) radiologic examination during surgery, 4) good postoperative care.
