[Experience in the use of external fixation devices in the treatment of limb bone fractures, their sequelae and complications].

The present paper reflects the experience of treatment of 243 patients with utilization of external fixation apparatus. Two methods of extrafocal perosseous osteosynthesis were employed: traction wire apparatus were utilized in 217 (89.3%) victims, rod apparatus--in 26 (10.7%). The construction of employed traction wire apparatus and method of its application have been described. Remote results of treatment have been followed in 194 (79.8%) patients. Fracture consolidation has been observed in 187 (77%) patients. Complications, registered in the process of application of apparatus of different constructions, have been analyzed. The authors have come to a conclusion about high efficiency of the employed apparatus, indicated obvious advantages of the rod apparatus.

The effects of physiologic dynamic compression on bone healing under external fixation.

The effects of early physiologic dynamic compression on fracture healing were studied in the dog. Transverse midtibial osteotomies were performed bilaterally and stabilized with a relatively rigid external fixation system in a neutralization mode (800 microns) to prevent compression of the osteotomy ends during weight bearing. On the 15th day, one osteotomy in each animal was subjected to dynamic compression through weight bearing by release of the fixator-telescoping mechanism (axial dynamization), while the other side remained unchanged as the control. Analysis of sequential roentgenograms showed that the callus distribution was more symmetric on the dynamic compression side. The two sides showed no significant differences in quantitative technetium-99 bone scans or in osteotomy-site blood flow. There were no statistical differences in new bone formation, bone porosity, or maximum torque between sides. The fixation had maintained the initially created osteotomy gap on the control side and tended to unite through a gap-healing mechanism. The dynamic compression side showed reduction in gap size and union by more of a contact-healing mechanism. There were no statistical differences in the rate of pin loosening, but its distribution according to pin location was significantly different between the two sides.

[Arthrodesis of the elbow using Ilizarov's external fixator].

Arthrodesis of the elbow was achieved without major surgery on the joint itself, while maintaining satisfactory pronation, supination, and function of the arm. To this end, the external fixator of Ilizarov was used in a compression set-up which interfered only moderately with daily life activities. Solid fusion was achieved after 4 1/2 months. To our knowledge this is the first time that this technique has been used for such an indication. The operative technique is described and its advantages emphasized.

[Corrections of limb deformities in children with Wagner's external fixator].

The authors describe a method of correction of limb deformities whilst allowing the length of the limb segment to be maintained. The apparatus used was the Wagner external fixator which first allows distraction at the site of an osteotomy followed by correction of angulation with suppression of this temporary lengthening.

Monitoring the healing of a tibial osteotomy in the rabbit treated with external fixation.

Fracture site axial rigidity was monitored non-destructively at weekly intervals during healing of tibial osteotomies in adult rabbits. Two groups of 20 rabbits each were treated with external fixators of two different rigidities. Four animals from each group were killed at 3, 5, 6, 7, and 8 weeks to determine the bending moments at failure of the healing fractures. Normal fracture healing was accompanied by characteristic phases in the development of fracture site axial rigidity. From 0 to 3 weeks there was a period of low and approximately constant rigidity, followed by a linear increase during 3 to 5 weeks to an approximately three to four times greater rigidity. The maximum average normalized axial rigidities were reached at 6 weeks and were 57% (high rigidity group) and 77% (low rigidity group) of the untreated contralateral controls. The maximum average normalized failure moments occurred at 8 weeks and were 48% (high rigidity) and 44% (low rigidity) of controls. The differences due to fixator rigidity were not statistically significant except for a large increase in failure moments at 3 weeks for the low rigidity group. Axial rigidities were correlated (r2 = 0.74 and 0.53, respectively) with failure moments, but only during the first 6 weeks. The monitoring technique provides a nondestructive means for following the biomechanical progress of fracture healing in an animal model. The occurrence of the characteristic increase in fracture site axial rigidity at 3 to 5 weeks can also be used to distinguish between normal and abnormal healing.

Treatment with external fixation of displaced talar fractures.

This article presents a case report on a 17-year-old girl who sustained a dislocation fracture of the talus, and was treated with external fixation. The fracture healed with a good result. After a 1-year follow-up, the patient had completely normal, pain-free mobility in the ankle joint. There were no radiographic signs of osteonecrosis.

External fixation and vascular damage: report of a case.

The case history is presented of a patient in whom the anterior tibial artery was clearly perforated by the distal pin of an external fixation device. This necessitated a dorsal pedis free flap instead of transposition of the flap to cover a degloved heel and sole. Review of the literature showed only a few case reports on vascular damage, suggesting that this complication is uncommon. In most cases, secondary erosion seems to be the cause, but as noticed by us direct arterial and/or venous damage is possible.

[Use of the AO plate as external fixation].

There are severe bony lesions in trauma and orthopedic surgery which are difficult to stabilize with all the well known methods. The use of a ASIF-plate applied as an external fixation can be a good alternative in exceptional situations. Those cases are discussed.

The "floating ankle": a pattern of violent injury. Treatment with thin-pin external fixation.

The "floating ankle" is an underappreciated pattern of injury that results from violent trauma and/or blast injuries in military personnel. It is characterized by an intact ankle mortise with a distal tibia fracture and an ipsilateral foot fracture, creating instability around the ankle. This pattern of injury may be the result of the military boot, which both protects the foot from immediate amputation or further injury and renders the distal tibia susceptible to fracture at the boot top. Four patients with open floating ankle injuries were treated with thin-pin circular fixation with good results. Two patients required bone transport for segmental loss. All patients are ambulatory without assistance or bracing. Thin-pin external fixation is a reasonable approach to this complex injury pattern, especially in the presence of marked soft tissue compromise with or without segmental bone loss.

Use of a New External Fixator for the Correction of Fixed Flexion Deformity of the Fingers.

Three patients with severe fixed flexion deformity of the fingers caused by trauma were reported. As an alternative treatment, a new mini external fixator was used to correct the deformities. The use of this device has made treatment of contractures simpler and more predictable. Gradual distraction and straightening was applied to loosen and extend the joints, followed by a period of mobilisation while still on the device. In all the three patients, this experimental device and approach led to improvement of the fixed flexion deformities. With use of this device, surgical release may not be necessary.

[Treatment of open leg fractures by double frame external fixation].

The authors review 36 cases of compound fractures of the tibia of type II and III (Cauchoix Classification). The treatment used was: 1. Careful cleansing of the sound. 2. The use of an external fixation (Hoffmann) as a double frame. 3. Continous irrigation. The authors stress that initial reduction should be accurate and that stability can be obtained by compression. Additional treatment was often needed, dependent on the stage of skin healing and the state of bone union. For the skin, Davis grafts or cross-leg flaps were used. For bone union, tibio-fibular grafts or reinforcing cancellous bone grafts (Papineau's technique) were used.

Medial external fixation with lateral plate internal fixation in metaphyseal tibia fractures. A report of eight cases associated with severe soft-tissue injury.

Eight patients with unstable fractures involving the articular surface and metaphyseal-diaphyseal bone of the proximal or distal tibia associated with severe soft-tissue injury or compounding wound were treated with irrigation, debridement, tetanus inoculation, antibiotic prophylaxis, and combined internal fixation with one-half frame external skeletal fixation for neutralization. All patients were followed to complete healing and functional restoration of the extremity. All fractures healed, but one superficial and one deep infection occurred. All patients achieved at least 110 degrees of knee motion. This method should be considered in unstable metaphyseal and articular tibia fractures not adequately stabilized with a lateral plate in which use of an additional medial plate is required for stability, but contraindicated because of the status of the soft tissues or extensive comminution of the bone.
