PURPOSE The purpose is to evaluate and report the results that treated with open reduction and internal fixation in delayed diagnosed fracture and dislocation of the hamatometacarpal joint. MATERIALS AND METHODS We evaluated 12 cases that had been treated with open reduction and internal fixation in delayed diagnosed fracture and dislocation of the hamatometacarpal joint. The mean interval between injury and operation was 34 days (21~60 days), the mean age of 12 cases was 28.1 years old, and mean follow-up period was 18 months. The computer tomography was done in all cases and the fracture and dislocation types were classified by Cain's classification. For the evaluation of results, pain scale, grasping power, range of motion of wrist and metacarpophalangeal joint were analyzed preoperatively and at final follow up, and the arthritic change of the hamatometacarpal joint was also checked. RESULTS According to Cain's classification, type Ia was one case, type Ib was two, type II was six, and type III was three. The pain scale was improved from 7.75 preoperatively to 0.92 at last follow up. The mean grasping power was improved up to 97.5% of normal. The preoperative range of motion of the wrist joint measured to be 60 degrees in extension and 70 degrees in flexion; the final range of motion indicated to be 75 degrees in extension and 80 degrees in flexion. The preoperative range of motion of the metacarpophalangeal joint measured to be 0 degrees in extension and 70 degrees in flexion; the final range of motion indicated to be 0 degrees in extension and 85 degrees in flexion. Carpometacarpal arthritis was developed in two cases. CONCLUSION The open reduction and internal fixation is considered as one of good treatment option in the delayed diagnosed hamatometacarpal fracture and dislocation.

PURPOSE To evaluate the radiographic and functional outcomes between who had unstable intertrochanteric fracture, treated with the ITST (lag screw design) and the PFNA (helical blade design). MATERIALS AND METHODS We selected each 17 and 13 patients of unstable intertrochanteric fracture which were treated with ITST or PFNA from April 2005 to December 2008. We evaluated the radiographic results by follow-up radiography and the clinical outcomes with the mobility score of Parker and Palmer, Social function scoring system. RESULTS The mean sliding distance of cervical screw with ITST nails was not shown significant differences than with using PFNA nails. The other factors were not statistically different. Decrease of mobility score of Parker and Palmer, Social function score were similar. 2 cases of cutting out was noted with ITST nails and 1 case of cutting out was noted with PFNA nails. CONCLUSION Unlike the existed biomechanical reposts, there are no differences that are clinical and radiological results in treatment of unstable intertrochanteric fracture using the ITST nails and PFNA nails.

PURPOSE To evaluate the clinical results of bipolar hemiarthroplasty in elderly patients more than 65 years of age with a femoral neck fracture. MATERIALS AND METHODS Forty-six bipolar hemiarthroplasties in 43 patients more than 65 years of age which could be followed more than 3 years were included in this study. The clinical outcomes were evaluated using Harris hip score, pain score and support score. The radiological results were analyzed by femoral stem loosening and bipolar cup migration. RESULTS The average Harris hip score was 88.7 (62~96) points. An excellent score was recorded in 34 cases, good in 7 cases, fair in 3 cases and poor in 2 cases. The average pain score was 39.3 points and there were no pain in 20 cases, slight pain in 17 cases, mild pain in 6 cases and moderate pain in 2 cases. The average support score was 9.6 points and 32 patients could walk without the use of any assistive devices. Two cases were converted to total hip arthroplasty due to femoral stem loosening with or without bipolar cup migration. CONCLUSION For the early ambulation and functional recovery of elderly patients with femoral neck fracture, bipolar hemiarthroplasty was considered as one of recommendable methods.
PURPOSE To evaluate the therapeutic results of intra-articular fracture of distal humerus treated through triceps sparing posterior approach. MATERIALS AND METHODS From February 2001 to December 2003, we reviewed total 9 cases of intra-articular fracture of distal humerus, which were treated by surgical treatment and were followed more than for 12 months. According to the OTA classification, nine cases were classified as type A; two, as type C1; five, as type C2; two. Triceps sparing posterior approach was used in all nine patients. An extensile posterior incision was used over the olecranon without triceps muscle injury. Exposure of the fracture site was done by obtaining medial-lateral mobility through dissection of medial and lateral edge of triceps muscle. Therapeutic results were assessed by bone union, duration for fracture union, complication. and for functional estimation, Mayo elbow performance score was checked and analysed. RESULTS The range of the elbow joint motion was flexion contracture 5.2 degree to further flexion 135.5 degree on average. Clinical results using Mayo elbow performance score were as follows; six excellent, three good. Compressive neuropathy of ulnar nerve which has been done anterior transposition was observed in one patient. CONCLUSION Triceps sparing posterior approach is useful surgical technique that provides sufficient exposure of medial and lateral condyle without injury of triceps muscle in intra-articular fracture of distal humerus to the extent of OTA type C2.
PURPOSE To assess the meaning of the unstable intertrochanteric fracture of femur with involvement of lateral cortex by analysing the radiologic result of the surgical treatment using a compression hip screw. MATERIALS AND METHODS Classifing patients (who has taken the surgical treatment for intertrochanteric fracture of femur using compression hip screw from January 1999 to June 2002) in our hospital with 24 patients who had not much difference statistically in the compression screw located within the femur, Tip-Apex distance (TAD) the Singh Numerical Value of osteoporosis. The results were divided into two groups, group A (without fracture extends through lateral cortex of femur: 16 cases) and B (fracture extends through lateral cortex of femur: 8 cases), when analyzing it. And then analyzed the final examination in the evaluation of electrical potential level by radiology, change of the inside and outside of neck-shaft angle, descent level of the screw and the change of the neck-shaft angle. RESULTS In the latest follow up, the sliding amount of the screw in group B, the average was 14.9+/-9.3 mm, and 6.7+/-3.6 mm in group A. There was no difference statistically (p value>0.05). In the varus change in group B, the average was 8.00+/-8.12degrees and in group A it ws 2.75+/-2.63degrees There was statistical difference(p value<0.05). In displacement after operation, it was 7.60+/-2.61 mm in group B and 0.5+/-1.80 mm in group A. There was statistical difference (p value<0.05). CONCLUSION The intertrochanteric fracture with involvement of lateral cortex of femur have to be considered as unstable fracture having tendency of displacement.

PURPOSE The purpose of this study is to analyze the clinical and radiological result of surgical treatment for femoral shaft nonunion. MATERIALS AND METHODS From January 1993 to December 1999, 21 cases of femoral shaft nonunion were treated surgically and followed for an average of 15 months. We analyzed initial cause of injuries, classification of fractures, and cause of nonunion in clinically and radiologically. The authors analyzed the average time to union and results after surgical treatment by rigid internal fixation with interlocking intramedullary nail and autogenous bone graft. RESULTS The mean duration of bony union was 22 weeks and bony union achieved in 18 cases(85.7%) of 21 cases. The complications were shortening of leg length and limping gait in 2 cases, partial limitation of knee joint in 2 cases, superficial infection in 2 cases. CONCLUSION Rigid internal fixation with interlocking intrameduallary nail and bone graft is useful method of treatment for femoral shaft nonunion according to cause and type of nonunion.
PURPOSE The malunited diaphyseal tibia fractures result in tibial shortening, angular deformities, gait disturbance, development of joint pain, etc. The authors analyzed the results of treatment consist of corrective osteotomy for diaphyseal malunion with internal or external fixation. MATERIALS AND METHODS The authors reviewed 18 cases of tibial diaphyseal malunion treated in Korea Veterans Hospital between January 1992 and December 1998. Mean follow-up period was 4.2 years. The preoperative deformities were varus, anterior or posterior bowing and shortening. The preoperative symptoms were knee joint pain, ankle joint pain, and gait disturbance. Corrective osteotomy was done on the site of malunion in all cases. Fixation were done with IM nailings(13 cases), plates(3 cases) and Ilizarov external fixator. We analyzed the unions radiologically and the knee pains with HSS score. RESULTS All malunions were successfully corrected. Mean duration of union was 4.5 month. In the coronal plane, preoperative varus deformity(mean 16.5degrees varus) was corrected to 3degrees of valgus. In the saggital plane, anterior and posterior bowing was corrected to neutral. In 15 cases of the patient with knee joint pain, the mean HSS score was improved from 69 preopertively to 82 postoperatively. CONCLUSION The correction of tibia diaphyseal malunion had good results by osteotomy at the malunited site and firm internal or external fixation. And it also improved knee joint pain significantly.

The femoral supracondylar and intercondylar fractures are difficult to be treated due to severe soft tissue damage, comminution, intraarticular extension of fracture and injury to the quadriceps mechanism frequently. The causes of nonunion are inadequate anatomical reduction, fixation failure, bone defect and infection occasionally, which is difficult to be treated.
The authors analyzed 16 cases with nonunion of femoral supracondylar and intercondylar fracture who had been treated surgicdlly from January 1990 to December 1991 According to AO/ASIF classification in the initial fracture patterns, type A were 8 cases, type B was 1 case and type C were 7 cases. The duration between initial treatment and surgical treatment of nonunion was 6 months in average. The causes of nonunion were fixation failure due to inadequate device selection in 9 cases, inadequate anatomical reduction or surgical technique in 4 cases and infection in 3 cases. The treatmentt were internal fixation with Dynamic condylar screw(DCS) in 9 cases, internal fixation with condylar blade plate in 4 cases, monofocal lenghtening with Ilizarov in 1 case and bifocal lenghtening with Ilizarov in 2 cases. According to Schatzker classification, the good result was obtained in 11 cases(68.8%). The complications were 3 knee joint ankyloses, 2 superficial wound infections, 1 delayed union and 1 deep vein thrombosis.
In conclusion, the requirement for the good result in treatment of nonunion are exact anatomical reduction, rigid fixation and autogenous bone graft.
Non-union of patella fracture was rare reported. We reported our experience with four cases of non-union of patella fracture treated by surgical intervention. Surgical management by skeletal traction and tension band wiring achieved union of the fracture in all four cases. The patients also recovered an excellent range of movement and strength in the affected knees.
The authors analysed the 40 patients of the lateral condyle fracture of the humerus in children who were admitted in Korea Veterans Hospital in Seoul from Jan. 1990 to Dec. 1997. The fracture type and the displacement was classified according to Milch type and Jakob stage. Clinical analysis was performed on 40 patients with lateral condyle fracture of humerus, who could be followed up. The patients were followed up from 12 months to 63 months with an average of 23 months. Average duration of bone union was 6 weeks after operation. The significant differences in outcome were notified from open reduction and internal fixation in comparison to closed reduction and percutaneous pinning. According to the criteria of Hardacre, we obtained excellent result in 16 cases(40%), good result in 22 cases(55%) and poor results in 2 cases(5%).
Fracture of tibial intercondylar eminence has a clinical importance in aspect of associated ligament injury, limited range of motion and joint instability The purpose of this study is to evaluate the intercondylar eminence fracture and to compare the results of treatment by method of arthroscopic reduction and pull-out suture with results of conservative treatment. The results were evaluated with Mayers and Mckeevers criteria of result and instability. 23 cases of avulsion fracture of tibial intercondylar eminence were reviewed. Most common type was type II Most common cause was traffic accident. Closed reduction and cast immobilization was performed in 12 cases, of which 10 cases had above good result initially, reduction with pull-out suture by arthroscopy was performed in 11 cases, of which 10 cases had above good refult. Type III B fracture were reduction with minimal arthrotomy because of the arthroscopic reduction was difficult. 2 cases of instability were in type III A and type III B. An instability case of type III A was treated non-operatively and the other of type III B was treated pull-out suture. 1 case of extension limitation was in type II which waf treated non-operatively because of multiple injury.
The supracondylar fracture of the humerus is the most common fracture of the elbow in children and is occasionally associated with significant residual complications such as cubitus varus deformity. Clincal analysis was performed on 32 patients with displaced supracondylar fractures of humerus, who were treated either by closed reduction and percutaneous pinning or by open reduction and internal fixation. The results were as follows : 1. The average age of the children was 6.8 years old in both sexes, and male to female was 21 : 11. 2. The extension type was 26 cases(82%), flexion type was 6 cases(18%) and the left side was more frequently involved. 3. According to Pirone classification, type II was 14 cases, type III 18 cases. 4. There was no significant difference in the mean duration of bony union between the percutaneous group and the open reduction group. 5. Cubitus varus deformity and limitation of elbow motion were more common complications in open reduction group.

Authors report 42 cases of humeral shaft fractures, which were treated with plate fixation in 19 cases and intramedullary(IM) nailing in 23 cases, from January 1992 to December 1996. The average time of operation in plate fixation was 100 minutes and that in Im nailing was 65 minutes. The nonunion in plate fixation was 2(10.5%)cases and that in IM nailing was 4(17.4%)cases. Other complications of plate fixation were 2 cases of wound infection and 2 cases of radial nerve palsy. Those of IM nailing were 1 case of limited motion of the shoulder and 1 case of wound infection. After reviewing above reslts, we concluded that there were no marked difference between the two operative method in bone union of humeral shaft fracture cxcept diversity of complication.
The ankle fracture with diastasis of distal tibiofibular jointis caused by an axial loading force with concomitant external rotation or other force. Many surgeons have treated this injuries by rigid fixation medial and lateral malleoli with syndesmotic fixation. But recently, syndesmotic fixation is not required to maintain the syndesmotic fixation on ankle fracture. seventy-five patients of ankle fracture with syndesmotic injury treated at Korea veterans Hospital from Jan. 1990 to Dec. 1996 were analysed in clinical and radiological aspect. The syndesmotic fixation was not necessary if the both medial and lateral injury was rigidly stabilized by fixation or ligament repair.
The scaphoid fracture is the most common fracture of the carpal bone in young men and has high incidence of nonunion. Many methods of treatment for nonunion of the carpal scaphoid have been described; bone grafting, screw fixation, pulsed electromagnetic field and cast, percutaneous pinning and Herbert screw fixation.
Two of the commonest methods of treatment are Matti-Russe procedure and Herbert screw fixation and this paper compares these two surgical treatments.
At the Department of Orthopaedic Surgery, Korea Veterans Hospital, from October 1988 to October 1994, 11 cases of the scaphoid nonunion had been treated by Matti-Russe procedure only (4 cases), Matti-Russe procedure with K-wire (2 cases) and Bone graft with Herbert screw fixation (5 cases) and followed up more than 1 year.
The results were as follows; 1. Among 11 cases, 10 cases were male and 1 case was female and the range of age was 19-46 years (Mean 26.2 years).
2. The sites of fracture were confined to the waist in 9 cases (82%) and prox 1/3 in 2 cases (18%).
3. The treatment methods were Matti-Russe only in 4 cases, Matti-Russe procedure with K-wire in 2 cases and Bone graft with Herbert screw fixation in 5 cases.
4. Postoperative cast immobilization was done for 16.5 weeks in the cases treated by Matti-Russe procedure and for 4 weeks in the cases treated by Bone graft with Herbert screw fixation.
5. The union rate was 91 % after postoperative 4 months (Mean 4.1 months).
6. The results of treatment were excellent in 7 cases (64%), good in 3 cases (27%) and fair in 1 case(9%). Therefore the Matti-Russe procedure and Bone graft with Herbert Screw fixation are good procedures in the treatment of scaphoid nonunion.
But, Bone graft with Herbert screw fixation is more useful in young men because of short periods of immobilization and early returning to work.

Recently, there is seen frequently the tibial fracture due to the increased traffic accident and the high energy trauma, and this fracture has many problems in a treatment because of nonunion, malunion, angular deformity, shortening and infection.
In the treatment of distal 1/3 fracture of tibia. interlocking intramedullary nailing has been popularized because it enables preservation of the range of motion of the joint, early weight bearing and early bony union.
Between Jan. 1988 and Dec. 1993 intramedullary nailing of the tibial fracture has been perfomed in 41cases, of which 38 cases were acute fractures and 3 cases were nonunion with folow up of more than one year.
The results were as follows; 1. Closed nailing technique was accomplished in 38 cases and 3 were opened.
2. The mean fracture healing period was 18.6 weeks and each mean fracture healing time was 19 weeks in Brooker nail and 18.5 weeks in interlocking nail, and so there was no significant difference in bone union time between two devices.
3. According to the functional classification of Klemm and Borner, out of 41 cases,26 were excellent,8 were good,5 were fair and 2 were poor.
4. The complications were infection in 4 cases, delayed union in 2 cases, angular deformity in 1 case and partial ankylosis of knee in 1 case.
5. In the cases associated with soft tissue injury and comminuted fracture of distal 1/3 of lower leg, Blocker nail was considered an useful treatment when distal interlocking screw fixation was not appropnate.
The incidence of intertrochanteric fracture of femur is increasing because of increasing number of old-aged people.
The goal in the treatment of an elderly patient with an intertrochanteric fracture is to restore the patient to his prefracture activity as soon as possible.
The purpose of this report is to review of the difficulty of treating the intertrochanteric fracture of femur in elderly patients.
The authors treated 213 cases of intertrochanteric fracture from Jan,1980 to Dec.1993.
We analyzed the clinical result of 73 cases intertrochanteric fracture with minimum 1 year follow up retrospectively.
The results were as follows.
1. The degrees of osteoporosis by Singh index were 27 cases in Grade III, 22 Cases in Grade II,14 cases in grade IV,5 cases in Grade I and 5 cases in Grade V.
2. By Tronzo classification of fracture, the most common type was 38 cases in type III, 17 cases in type II and 8 casesintype V.
3. The operation method were compression hip screw(38 cases), Jewett nail (12 cases), Ender nail(17 cases), multiple pinning (5 cases), and primary kerniarthoplasty(3 cases).
4. Average bony union time was 13.2 weeks in compression hip screw group, 14.5 weeks in Jewett nail group,14.7 weeks in Ender nail group and 15.4 weeks in multiple pinning group.
It is reported that infected pathological fracture of distal femur has a difficulty in treatment The difficulties lie in; choosing a internal fixator, adequate sequestrectomy of infected lesion, limb shortening, long duration of immobilizatlon.
We uses the external fixator in treatment of distal femoral fracture because it needs less devices in fracture site than the internal fixator, and it could get a rigid fixation. we uses the Ilizarov apparatus. The merits of Ilizarov are, early weight bearing; limb lengthening and easy compression and distraction. The one case in which limb length discrepancy is occured, is peformed by limb lengthening.
In this study, we are going to argue about the two cases, of infected non-unlon of distal femoral fixation comparing with one another.
The ankle is a complex, weight bearing joint and its injury results in a severe functional disturbance of complex anatomical characteristics. It is very important to understand the mechanism of the trauma in order to make defenite diagnosis and proper treatment. The authors analysed 92 cases(92 patients) of the ankle fractures which were operated in Orthopedic Department, Korea University Hospital from Sept. 1980 to Dec. 1991. The results obtained were as follows ; 1. Of the 92 cases, male was 61 cases(66.3%), female was 31 cases(33.7%) and average age of the patients was 39.9 years.
2. The causes of the injury were slipping down, traffic accident, sports injuries and falling down in orders.
3. Open fractures were 12 cases(13.0%) and closed fractures were 80 cases(87%).
4. The most common type of the ankle fracture was supination-external rotation type(32 cases, 34.8%) and next was pronation-external rotation type(26 cases, 28.3%), according to the classification of Lauge-Hansen.
5. The associated fractures with ankle fracture were 26 cases (28.3%).
6. The best result was supination-adduction type and the worst result was pronation dorsiflexion type, when assessed according to the criteria of Meyer.
7. There were 11 cases of complications(12.0%), in which 6 cases of traumatic arthritis, 4 cases of malunlon and 1 case of nonunion.
8. The accurate reduction and rigid internal fixation to the fracture of lateral malleolus of dlstal fibula and tibiofibular diastasis was important in the treatment of the ankle fractures.
