| description | Introduction Failures in surgical rehabilitation of patients with humeral fractures result in the formation
of a multicomponent complex of pathological symptoms, including nonunion or bone defect, changes
in the shape and length of humeral fragments, development of persistent angiotrophic disorders of the upper
limb and contractures of the shoulder and elbow joints. Despite the effectiveness of using metal implants,
there are risks in surgical osteosynthesis in complex anatomical and functional lesions.
The purpose of the work was to demonstrate a new technology of bone plasty with free fragments
of the fibula as a bone-plastic material for restoring the integrity of the humerus in bone nonunion
and defects in the conditions of transosseous osteosynthesis and transosseous fixation of the grafts
with wires.
Materials and methods A free autograft of the fibula shaped as a cylindrical fragment, which was resected
proximally to the ankle joint level at 8.0-9.0-cm distance, was used as a bone plastic material. The fibula graft
was fragmented intraoperatively. Fragments were implanted along the periphery of the humerus fragments
overlapping of the pseudarthrosis site. Free autografts of the fibula were transosseously fixed with wires.
A wire/half-pine Ilizarov apparatus with three external supports was placed to fix the segment.
Discussion The "gold standard" material for bone plasty is autogenous bone. If defects and pseudoarthroses
of the humerus are located in the distal metaepiphysis, the application of the fibular cylinder-shaped fragment
with intraosseous reinforcement of the humeral bone is technically difficult. Open co-aptation of the humeral
fragments with adequate contact between them and application of the optimal autogenous bone-plastic
material which overlaps the pseudarthrosis zone to increase the volume of bone mass ensure the restoration
of bone regeneration in the pseudarthrosis zone. External fixation is optimal for fixation of bone fragments
and grafts.
Conclusion The originality of the developed technology lies in the use of several free bone autografts
from the fibula implanted along the periphery of the humeral fragments junction. The area of active
osteogenesis is thus created due to the combined effect of open co-aptation of the ends of the humeral
fragments with resection of the endplates and bone autogenous grafts that overlap the problematic area.
Additional transosseous fixation of bone autografts with wires ensures the stability of free grafts. Controlled
fixation of humeral fragments with compression and adequate contact of the fragments is achieved
with the Ilizarov apparatus. |
