Valgus deformity of the first finger stop refers to the common options pathology of locomotor apparatus in adolescents.
There is a method of treatment of valgus deformity of the first toe, consisting of resection of the medial bony-cartilaginous exostosis head of the first metatarsal bone, cooligomerization on the lateral surface of the first metatarsophalangeal joint arthroplasty and arthrodesis of the first cuneiform-metatarsal joint (Lapidus P.W. Operative Correction of Metatarsus Primus Varus in Hallux Valgus Surg Gynecol Obstet 58:183, 1934).
The disadvantage of this method is the need for a substantial shortening of the first ray of the foot due to resection of the articular surfaces of the first metatarsal and cuneiform bones to shorten the first resection of sphenoid bone to adapt arthrodesis surfaces and correction of bringing the first metatarsal bone.
The objective of the proposed method is the one-stage correction of valgus deformity of the first finger preserving the length of the first ray of the foot.
The technical result of the task is achieved in that in the method of treating hallux valgus of the first toe hold the offset of the first wedge-shaped bone in the medial direction, adapting the front part of the first sphenoid bone to the base of the pen is th metatarsal bone due to economical resection, after resection of the medial bony-cartilaginous exostosis head of the first metatarsal bone and cooligomerization on the lateral surface of the first metatarsophalangeal joint, restore the correct value in the first planetevovideos joint, correct deformity of the foot, and recording the obtained ratio with the creation of arthrodesis of the first planetinvader joint.
Figure 1 presents photographs of the patient before and after surgical treatment.
Figure 2 shows x-rays of the patient before and after surgical treatment.
The operation is as follows. From the incision along the medial edge of the dorsal surface of the foot length of 5 cm is cut first milinovich articulation, as well as dissection of the first milusheva ligaments. After this first sphenoid bone is displaced medially through derotation, and its anterior adapts to the base of the first metatarsal bone due to economical resection. The first metatarsal bone is displayed in the middle position. Resected its proximal articular surface. Then an incision is made along the inner surface of the first metatarsophalangeal joint, the envelope of the exostosis. Disassembled soft tissue flap. You capsulotomy first metatarsophalangeal joint. Resected exostosis. Soft tissue l the scoot filed in slight tension. Restores the correct value in the first planetevovideos joint, are mapped Introduzione surface. Is modeling the first resection of sphenoid bone. The resulting ratio is fixed needle Kirchner axis and two cross-spokes Kirchner, passing through the zone of fusion. The wound is closed in layers.
Clinical example. The patient, 17 years of age. Combined flat feet. Valgus deformity of the first fingers of both feet. On radiographs stop before surgery (figure 1), the angle between the first cuneiform and first metatarsal bones, is 44°, reflecting the severe deformity of the first ray of the foot. The purpose of simultaneous correction performed surgery, including mobilization and derotation first sphenoid bone, creating arthrodesis of the first planetinvader joint, the cap opening of the first metatarsophalangeal joint and resection of the exostosis. The x-ray after surgery (figure 2), the angle between the first cuneiform and first metatarsal bones is 5°, which corresponds to the normal value. Thus, to achieve full correction of the strain components. The shape of the foot proper. Range of motion in the first metatarsophalangeal joint is full. The patient uses ordinary shoes.
The method of treating hallux valgus of Pervov the toe, characterized in that hold the offset of the first wedge-shaped bone in the medial direction, adapting the front part of the first sphenoid bone to the base of the first metatarsal bone due to economical resection, resection of the medial bony-cartilaginous exostosis head of the first metatarsal bone and cooligomerization on the lateral surface of the first metatarsophalangeal joint, restore the correct value in the first metatarsal-cuneiform joint, correct deformity of the foot, and recording the obtained ratio with the creation of fusion of the first metatarsal-cuneiform joint.
