ABSTRACT
PURPOSE: To compare the results and complications of interlocking IM nailing and plate fixation by posterior approach in the treatment of traumatic humeral shaft fracture MATERIALS AND METHODS: From March 1997 to March 2003, 49 patients undergone operation due to traumatic humeral shaft fracture. Follow-up was over one year. 28 patients operated with interlocking IM nailing initially and 21 operated with plate fixation by posterior approach prospectively. Statistics were compared using clinical and radiological outcomes and complications. RESULTS: Radiologically, bone union was observed after an average of 14.3 weeks in IM nailing, and 11.7 weeks in plate fixation. So plate fixation showed earlier bone union (p=0.012). Nonunion occurred in 4 cases (14.3%) operated with IM nailing, and 1 case (4.8%), that was open shaft fracture, with plate fixation. Nonunion occurred more frequently when operated by IM nailing. 6 cases showed limitation of shoulder movement due to damage of the rotator cuff by IM nail entry site. 1 case showed radial nerve palsy, and 1 case showed axillary nerve palsy in the case of IM nailing. Also, secondary surgery due to complications was operated in 9 cases (32.1%) in IM nailing and 1 case (4.8%) in plate fixation (p=0.03). CONCLUSION: In the case of traumatic humeral shaft fracture plate fixation by posterior approach was more useful than IM nailing in the decrease of complications and bone union. Such approach is thought to be an excellent method for anatomic reduction and nerve exploration in the case of open and comminuted fracture which accompany nerve injuries

Femoral fractures in adults frequently need an extensive dissection for attainment of adequate internal fixation, frequently leading to nonunion, infection and derangement of joint motion. Retrograde IM nailing, compared to the conventional methods, has advantages of reducing periarticular soft tissue dissection and establishing a load sharing construct reducing hardware failure. The purpose of this study is to verify the advantages of retrograde IM nailing by retrospective evaluation of the results of adult femoral fractures treated by this technique. The matrials were 17 femoral fractures in 15 patients treated by retrograde IM nailing and followed up for more than 1 year. The fracture was located in the middle third of the shaft in 5 and distal third in 12. The latter consisted nf 6 cases of type Al, 4 cases of type A2 and 2 cases of type A3 by Miiller's classification. The results were as follows; 1) Fracture union was achieved at an average of 17.5 weeks. 2) Full range of knee motion was gained in 15/17 knees (88%). 3) Complication occurred in 2 knees. One nonunion and one angulatory malunion. 4) There was no infection, no femoral shortening or implant failure. In conclusion, retrograde IM nailing of adult femoral fracture is an effective method in selected cases such as far distal femoral fracture, ipsilateral femur neck and shaft fractures, floating knee, post-TKR femoral fracture and so on. The merits of this technique are rigid fixation which is difficult to obtain with others, no need of fracture table, short operative time and mimium blood loss. However, It has potential problems such as difficulty in insertion of proximal locking screw and need for an arthrotomy to remove hardware.

The decrease of bone density after fracture is a well-known phenomenon. Several studies of the changes of bone density after fracture demonstrated bone density decreased not only at the fracture site, b ut also along the whole fractured bone. Being treated with locked intramedullary (IM) nailing, 15 patients with the long bone fractures of lower limbs were examined by Quantitative Computed Tomography (QCT) or Dual-Energy X-ray Bone Densitometer (Lunar DPX-L) a few days after nail removal. In the cases of QCT (5 patients of the tibia shaft fracture), cortical bone density, cortical thickness and geometrical shape (i.e. external antero-posterior and medio-lateral diameters) of the fracture site were compared to those of the contralateral side. On the other hand, in the case of Lunar' (5 patients of the tibia shaft fracture & 5 patients of the femur shaft fracture), only cortical bone density was compared to that of the contralateral side. The results of this study were as follows: 1. When treated by the locked intramedullary nailing of the long bone fractures, the bone density of the tibia & femur shaft fractures measured from the fracture site, proximal and distal sites to mid-fracture decreased. 2. There was a difference in the bone density of the uninjured long bone diaphysis of the tibia & femur shaft fractures. That is, in the case of the tibia shaft fracture, the bone density of the ipsilateral femur diaphysis measured by QCT increased 2 %, and increased 7 % when measured by Lunar. But, in the case of the femur shaft fracture, the bone density of the ipsilateral tibia diaphysis measured by Lunar decreased 4%. 3. In the case of the tibia shaft fracture, the cortical thickness in the fracture site measured by QCT increased 72 %, and external antero-posterior and medio-lateral diameters increased 7 % and 63 %. It seemed to be the formation of peripheral callus due to medullary reaming preceding intramedullary nail insertion. Therefore, this clinical study demonstrated that the mechanical property of the long bone fractures was restored and restricted weight bearing hardly needs to recommended when the nail was removed after the fracture union. 4. The bone densities of the tibia shaft fratures measured by QCT were not different with those measured by Lunar.

The standard treatment of adult femoral shaft fractures is the closed intramedullary nailing using a fracture table, but in polytraumatized patients, this method may be difficult due to concomitant adjacent injury. So, we report on the technique of closed intramedullary nailing without a fracture table for adult femoral shaft fracture using "joystick" technique on radiolucent table in supine position. Among 15 cases, two were open fractures, three were proximal 1/3, seven were middle 1/3, two were distal 1/3, and theree were segmental fractures. According to the Winquist Hansen classification, five type I, four type II, three type III, three were type IV. The eleven patients out of the fifteen were operated within 48 hours. The average operation time was 105 minutes, and the amount of bleeding was below 300cc. Forty-seven percent was anatomically reduced, forty percent had below five degree of angular deformity or below five milimeter of shortening, thirteen percent had above five degree of angular deformity of above five milimeter of shortening. The closed intramedullary nailing of femoral shaft fractures without fracture table using radiolucent table and "joy stick" technique is an effective and safe method in multiple injuries. And it reduced the operation time by reducing the preoperation time including preparing of a fracture table.

The authors studied 54 patients (55 cases) of femoral shaft fractures treated by compression plate fixation and IM nailing from August 1986 to December 1991. The purpose of this study is to analyse comparatively the radiological and clinical results between the compression plate fixation and IM nailing in femoral shaft fracture of adult. The obtained results were as follows: 1. Among the 54 patients, the ratio of male and female was 44: 10, and the highest in cidence of age was between 3rd and 4th decades. 2. The main cause of injury was traffic accident in 38 cases. 3. The most common fracture type was B1-② in ten cases by AO-ASIF classification. 4. The mean duration of union was 13 weeks in compression plate fixation by the Koostra's criteria and the average 23 weeks in IM nailing by the Bjorens criteria. 5. The clinical result according to Margerl et al, was good in 25 cases (80.6%) with compression plate fixation and good in 20 cases (83.3%) with intramedullary fixation. 6. Complications of compression plate fixation were metal failure in 2 cases and deep wound infection in 1 case, and 1 case of femur neck fracture during operation and 1 case of metal failure in intramedullary fixation.

The intramedullary nailing is one of the most available method in treatment of femoral shaft fracture. Since the development of Kuntscher naukl in 1940, new design such as Grosse-Kempf IM nailing became widely used by more applicable level of femoral shaft fracture. Therefore, complications of intramedullary nailing was rarely seen. The authors analysed complications in 7 cases of intramedullary nailing for treatment of femoral shaft fracture in Koryo General Hospital from Jan. 1991 to Jan. 1993., and the results were as follows; 1. The average age was 40.5 years and all patient's sex were male. 2. Among 7 cases, complications were delayed union in 4 cases, metallic failure in 2 cases and femoral neck fracture in 1 case. 3. Among 4 cases of delayed union, 3 cases treated by weight-bearing after dynamization and 1 case treated by bone graft after dynamization. 4. Metallic failure occurred in 2 cases, 1 case developed metallic corrosion in medullary canal, the other case developed metal failure at fracture. 5. Fomoral neck fracture in 1 case was treated by multiple Knowles' pins.

161 patients with tibia fracture were treated by closed intramedullary nailing at the department of Orthopedic Surgery, Eul-Ji General hospital, Dae Jeon, during 5 years from January, 1988 to April, 1993. 134 of these patients were performed with Kiintscher IM nailing and 27 patients with Ender nailing. Rigid IM nailing is the method of choice in tibia shaft fracture with rigid fixation, low complication, wide indication and early weight bearing, but the treatment of segmental fracture of the tibia will have many difficulties because of severe displacement, severe comminution, massive soft tissue damage and lack of blood supply at fracture site. Either antegrade or retrograde Ender nailing was of value for the management of segmental fracture which was too proximally or too dixtally located to insert interlocking screws, open fracture and soft tissue injury around Kiintscher insertion site. The result as fllows; 1. 43 fractures were open and 118 were closed. 69 fractures involved the distal portion, 55 fractures the middle portion, 13 fractures the proximal portion of the tibia and 24 fractures were segmental. 2. Among the 161 eases, 114 cases were male and 47 cases were female, the most common ages were ranged from 21 year to 30 year, involving 44 cases. 3. The most common cause was traffic accident. 4. Average intervals from injury to operation were 6.34 days(closed fracture) and 9.84 days(open fracture). 5. The mean durations of the bone union were 18.90 weeks(closed fracture) and 16.46 weeks(open fracture). 6. Complication included 7 cases delayed union, 3 cases nonunion, 8 cases superficial infection, 4 cases joint stiffness, 3 cases nail migration, 2 cases angular deformity, 2 cases rotational deformity, 1 cases osteomyelitis.

We studied 75 cases of conventional Kuntscher intramedullary nailing and 52 cases of interlocking intramedullary nailing from July 1980 to October 1988 for femur shaft fractures. The conventional Kuntscher intramedullary nailing was used for fresh fracture and the interlocking intramedullary nailing was used not only fresh fracture, but also unstable fracture, nonunion and pathologic fracture. The conventional Kuntscher intramedullary nailing was frequently used in middle one-third level, but the interlocking intramedullary nailing could be applied widely from subtrochanteric area to supracondylar level in femur. The average operation time in patient who had no associated injury was 3.6 hours in conventional Kuntscher intramedullary nailing and 3.25 hours in interlocking intramedullary nailing. Time period for union was much less in interlocking intramedullary nailing than conventional Kuntscher intramedullary nailing. Some kinds of immobilization was needed shortly in conventional Kuntscher intramedullary nailing but immediate postoperative ambulation was possible in interlocking intramedullary nailing. Interlocking intramedullary nailing can prevent the angulation, shortening and trochanteric bursitis due to migration of the intramedullary nail.

The intramedullary nailing is a good method of treatment in femur shaft fracture but it is not available in some fracture pattern or fracture level. And it is very difficult with conventional Kiintscher nailing to prevent torsional stress and fix rigidly in unstable fracture of the femur shaft. The unstable fracture by comminuted fracture or segmental fracture, nonunion and pathologic fracture needed the rigid fixation. Interlocking Kuntscher IM nailing can provide antitorsional stability, good axial alignment and prevent shortening of the fracture site, also allow early ambulation and joint exercise. We analysed 51 patients 52 cases of interlocking Kiintscher IM nailing from May 1981 to March 1988. The interlocking Kuntscher IM nailing prevents the rotational and axial roading. The interocking Kuntscher IM nailing has expanded its application in fracture pattern and fracture site. The interlocking IM nailing provides rigid fixation in severe comminuted fracture. segmental fracture, long spiral fracture, and other several unstable fractures and eliminates splinting or external supports, so it is possible doing early joint exercise. The interlocking Kuntscher IM nailing was also considered best internal fixation method in pathologic fracture or sever osteoporosis. The static interlocking for rigid fixation and the dynamic interlocking method for axial compression to fracture site during weight bearing can be adapted appropriately to fracture pattern. Radiation hazard during the interlocking nailing is not considerable.
