Use of a Distraction Dynamic External Fixator in the Treatment of Comminuted Middle Phalanx Base Fractures: Sang Woo Kim, Chae Chil Lee, Sang Hun Ko, Il Yeong Hwang, Min Seok Kim, Woo Young Jin; J Korean Fract Soc 2019;32(1):1-5. Published online January 31, 2019; DOI: https://doi.org/10.12671/jkfs.2019.32.1.1

PURPOSE
This paper suggests the use of distraction dynamic external fixators (DDEF) for the treatment of proximal middle phalanx fractures.
MATERIALS AND METHODS
Seven patients, who were diagnosed with comminuted intra-articular fractures at the base of the middle phalanx from February 2014 to November 2016, were enrolled in this study (volar aspect 6 cases, dorsal aspect 1 case). They underwent a closed reduction under a C-arm image intensifier, and DDEF was applied with general anesthesia. Range of motion (ROM) exercise was encouraged after 3 to 5 days postoperatively, and DDEF was removed after 5 weeks. Subluxation, angulation and displacement were evaluated 6 weeks postoperatively.
RESULTS
The patients who were treated with DDEF showed a normal proximal interphalangeal joint ROM (100Â°), and there was no subluxation or displacement on the X-ray film 6 weeks postoperatively. In addition, there were no signs of infection, such as local heat, redness, and pus-like discharge.
CONCLUSION
DDEF helps maintain the reduction and reducing forces through the ligamentotaxis. The joint stiffness is reduced, which it makes early return to daily life easier.

Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.46

Abstract: PURPOSE
To evaluate the follow-up result of 11 cases that were operated with internal fixation of scapular neck and internal fixation of clavicle or acromioclavicular dislocation for severely displaced floating shoulder which was high energy injury and unstable.
MATERIALS AND METHODS
We examined the scapular neck fracture with clavicle fracture or acromioclavicular joint dislocation by multidisciplinary research from August 1997 to July 2004. The scapular neck fractures were operated in the case of translational displacement of more than 25 mm and angular displacement of more than 45 degrees with 3.5 mm reconstruction plate fixation and internal fixation for clavicle fracture or acromioclavicular joint perpormed simultaneously. And we evaluated 11 cases that can be followed up for more than 9 months.
RESULTS
We achieved bony union in all cases. In ASES functional score, we got average 89.2 (75~95) points. In Rowe functional score, we got average 89.1 (75~100) points. In complication, there was external rotation weakness in 1 case.
CONCLUSION
In severely displaced floating shoulder due to high energy injury, we got good clinical and functional result after internal fixation for scapular neck and clavicle or acromioclavicular joint.

Treatment of Femoral Intertrochanteric Fracture with Proximal Femoral Nail: Bum Soo Kim, Sogu Lew, Sang Hun Ko, Sung Do Cho, Jeung Hun Yang, Moon Su Park; J Korean Fract Soc 2004;17(1):1-6. Published online January 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.1.1

Abstract PDF

PURPOSE
To evaluate the usefulness of proximal femoral nail in the treatment of intertrochanteric fracture.
MATERIALS AND METHODS
The authors investigated the classificaton of fracture, operation time, the amount of intraoperative and postoperative bleeding, the amount of transfusion, postoperative ambulation status, bone union time and the complication among 45 cases who were treated with proximal femoral nail from Jan. 2001 to June 2002.
RESULTS
The mean operation time was 116 minutes, and the amount of bleeding was 524 ml in average. The amount of intraoperative transfusion was 1.4 pints and that of postoperative transfusion was 1.1 pints. The complications were the intraoperative penetration of antirotational screw through the femoral neck in 2 cases, separation of the fracture fragment while inserting the nail in 4 cases, irritation of skin by retropulsion of antirotation screw in 2 cases, and penetration of antirotation screw through femoral head in 1 case.
CONCLUSION
Proximal femoral nail was effective for the treatment of intertrochanteric fracture, however the surgeon should be carful about collision of the insertion handle against pelvis when the fracture line coincides with the insertion point of nail, especially in obese patients.

Arthroscopic-Assisted Reduction and Internal Fixation of Patella Fractures: Sang Hun Ko, Sung Do Cho, Hwa Yeop Na, Woo Suk Kim, You Young Jeong, Chang Yeul Kwag, Bum Soo Kim; J Korean Soc Fract 2003;16(4):482-489. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.482

Abstract PDF

PURPOSE
The aim of this study is to report the clinical effectiveness of arthroscopic-assisted reduction and internal fixation of patella fractures.
MATERIALS AND METHODS
We analyzed fifteen patella fractures, which had been operated by using an arthroscopic-assisted technique from January, 2000 to April, 2003 at our hospital. After clinical follow-ups for at least 1 year, clinical analyses had been done by using the Cincinnati Knee Rating System Score, Lysholm Score Scale, and radiological findings.
RESULTS
In our study group, the Cincinnati Knee Rating System scores were from 80 to 100, with a mean of 89.9. The Lysholm Scoring Scale scores ranged from 81 to 100 with a mean of 90.8 for the same group. Radiologically, we obtained complete anatomical reduction of articular surfaces in 80 percent of cases. Arthroscopic-assisted reduction for patella fractures brought clinically satisfactory results that are accurate articular surface reduction, early recovery of motion range, knee joint stability and minimal soft tissue damage, etc.
CONCLUSION
The operative treatment for patella fractures using arthroscopic-assisted reduction is an effective alternative method to open reduction.

Modified Tension Band Wiring using Cortical Screw for Displaced Medial Malleolar Fractures: Jong Oh Kim, Sang Hun Ko; J Korean Soc Fract 2002;15(4):459-464. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.459

Abstract PDF: PURPOSE
To evaluate the clinical results of minimal incision and modified tension band wiring using 3.5mm cortical screw in the treatment of ankle fracture including displaced medial malleolar fractures MATERIALS AND METHODS: From March 1997 to May 2001, 77 patients were treated by modified tension band wiring using minimal incision about 4cm for medial malleolar fracture.
RESULTS
According to Lauge-Hansen classification, there were 47 supination-external rotation type fractures (61%), 14 supination -adduction type fractures (18.2%), 10 pronation-external rotation type(12.9%), 6 pronation-abduction type fracture(7.8%). The average time to union was 12.5weeks. In the functional outcome (according to Meyer and Kumler), 71 patients(92%) showed excellent results.
CONCLUSION
We concluded that modified tension band wiring using cortical screw proved effective fixation method in the treatment of the displaced medial malleolar fracture. The merits of this procedure are minimal incision about 4cm and preservation of blood supply on suprafracture area due to not injuried periosteum, stable fixation and early range of motion of joint, simple procedure and reduced surgical time.

Attritional Rupture of the Flexor Tendons after Malunion of Distal Radial Fracture : Report of One Case: Jae Do Kang, Kwang Yul Kim, Sang Hun Ko, Hyung Chun Kim, Kyeong Chil Jung, Moon Sub Yim; J Korean Soc Fract 1997;10(4):929-933. Published online October 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.4.929

Abstract PDF: There are a few of reports of delayed rupture of flexor tendon around the wrist and hand by attrition. Only 4 cases of delayed flexor tendon rupture of finger except rupture of flexor pollicis longus after Cellos fracture were reported until now. Several causes of the delayed rupture of the tendon around the wrist and hand were reported by many authors. Cellos fracture is one of the cause of the attritional rupture. But the frequency of the attritonal rupture of the flexor tendon was only one-third of the extensor tendons. Furthermore, flexor tendons of the finger were less commonly affected than that of the thumb by their anatomical features. We would like to report a very rare case of delayed rupture of flexor digitorum profundus on 73 year old male patient by attrition on the bony spur which was formed by malunion of distal radial fracture about 10 years ago. They were treated by direct repair for ring finger and free tendon graft with flexor digitorum sublimis of middle finger for little finger. After 1 year follow up, range of motion and flexion power were recovered to nearly normal.

Hemiarthroplasty for Treatment of Proximal Humerus Fracture: Chung Nam Kang, Jong Oh Kim, Sang Hun Ko, Young Do Koh; J Korean Soc Fract 1997;10(3):685-693. Published online July 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.3.685

Abstract PDF: From 1993 to 1996, we have used hemiarthroplasty on shoulder for comminuted fracture and fracture-dislocation of proximal humerus. The study reviewed 8 patients with on average age 62.1 years. The hemiarthroplasty was performed at average 5 days following injury. The purpose of this study was to evaluate pain, function, range of motion, strength, patients satisfaction. All cases was performed using cement and surgical approach was deltopectoral. Average follow up was 33 months after operation(range, 24 to 45 months). According to UCLA shoulder rating scale, 5 patients(63%) were satisfactory and 3 patients(37%) were unsatisfactory. Average active flexion was 110, and average abduction was 97 and average external rotation was 39, average internal rotation to the first lumbar vertabrae. Average humeral offset on fractured shoulder was 20.5 and average humeral offset on normal uninjured shoulder was 30.8. For functional improvement of shoulder hemiarthroplasty, We concluded humeral length restoration and humeral offset preservation is very crucial factors.

Complications of Interlocking Intramedullary Nailing for the Humeral Shaft Fracture: Chung Nam Kang, Jong Oh Kim, Dong Wook Kim, Young Do Koh, Jong Keon Oh, Sang Hun Ko, Seung Wook Jeong; J Korean Soc Fract 1997;10(3):669-677. Published online July 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.3.669

Abstract PDF: Several advantages of intramedullary nails over plates and external fixators have led to an anpansion of the surgical indications for humeral shaft tractures. But, various morbidities due to proximity of several important structures, such as rotator cuff and radial nerve, follwed the operation. We reviewed our experience with 23 cases of humeral shaft fractures that were treated by interlocking intramedullary nailing to evaluate the pitfalls and the complications of this technique. Fifteen men and 8 women were followed for average 19.5 months. Twenty one (91.3%) of them had midshaft fractures. According to AO/ASIF classification, type A was most common(60.9%), and followed by type B(26.1%) and type C(13.O%). Eighteen of them had associated injuries - 5 radial nerve palsies, 1 Volkmans ischemic contracture, and 14 had fracture of other sites. Indications for interlocking intramedullary nailing were unsatisfactory reduction after closed reduction, fracture of the ipsilateral upper extremity, segmental fractures, and multiple injuries. The operation was performed average 6.7 days after injury. The final results were evaluated with radiographs for quality of union and with physical examination for functional status of the shoulder. There were four cases of complication associated with increase morbidity. A post operative radial verve palsy, associated with the distal interlocking screw fixation was developed due to inappropriately short nail insertion. And in one case, fracture healing was delayed due to distraction of the fracture gap after nailing. In another case subacromial impingement was developed secondary to protruded nail tip because the length was thought be the common underlying causative factor. Finally there was a case of iatrogenic fracture at the site of distal interlocking screw fixation and it was thought to be a technical problem. The results gave us the conclusion that inappropriate nail length was the common underlying causative factor of the complications. Therefore in the interlocking IM nailing for the humeral shaft fractures, accurate measurment of nail length is one of the most cirtical factor for the good final result.

Treatment of Fracture-Dislocation of Tarsometatarsal Joint: Chung Nam Kang, Jong Oh Kim, Sang Hun Ko; J Korean Soc Fract 1996;9(3):715-724. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.715

Abstract PDF: The tarsometatarsal fracture-dislocation are unusual freguency. Lesion in this area are generally the result of a high energy traulna and difficult to recognize on standard radiographs. Twenty-one casei of fracture and dislocation of the tarsometatarsal joint were treated by open or closed reduction from January 1991 to April 1996. We assessed clnical result & treatment result and the following results were obtained. 1. Anatomical reduction is likely to lead nearly normal function & little complications. 2. Due to soft tissue interposition, espicially interposition of tibialis anterior, and marked articular comminution, early closed reduction was failed in 3 cases. If the closed reduction is tossed, then open reduction and internal fixation was performed. 3. In cases of nearly anatomical reduction, good prognosis was obtained. 4. Accurate accessment of AP & oblique & lateral projection of radiographs were very adventa geous & important. 5. Open anatomical reduction was superior to closed reduction & percataneous pining & cast immobilization alone.
