peroneal tendon transposition

Transposition of the iliac tendon tendon for sequelae of polio - surgical treatment of clubfoot. Paralytic horseshoe valgus, usually the tibialis anterior and posterior tibial muscles are weak, the tibia long and short muscles are strong, and the calf triceps are powerful and contracture. The triceps of the calf will bring the foot to the horseshoe, while the sacral muscle will bring the foot to the valgus position. It is very difficult to treat this deformity when the foot bone is immature. Simple tibialis anterior muscle paralysis usually only causes moderate valgus deformity. This deformity is more obvious in dorsiflexion, and it will disappear when the plantar flexion occurs. The long iliac tendon can be transposed to the cuneiform bone. Simple posterior tibial muscle paralysis can cause flat valgus deformity. Under normal circumstances, this muscle causes the foot to varus, and when it is paralyzed, valgus deformity appears. Treatment for this malformation may include transposition of the long iliac crest, long flexor tendon, and long flexor tendon. Simultaneous paralysis of the anterior and posterior tibia of the humerus resulted in an extreme deformity similar to the flat foot of the rocking chair. It was feasible to transposition the tendon to replace the posterior tibial muscle. Other tendon transpositions could be used to replace the tibialis anterior muscle. For the horseshoe valgus deformity of children aged 4 to 10 years, it is feasible to extend the achilles tendon and the joint out of the joint. For patients with mature bones, the horseshoe valgus deformity usually requires three-joint fusion and Achilles tendon lengthening, and appropriate tendon transposition is performed after 4 to 6 weeks. Treating diseases: foot valgus Indication Transposition of the iliac tendon tendon for simple tibialis anterior palsy usually only causes moderate valgus deformity. This deformity is more pronounced in dorsiflexion and disappears when the plantar flexion occurs. Preoperative preparation Regular preoperative examination. Surgical procedure 1. Make an oblique incision parallel to the dermatoglyph at the midpoint between the distal tip of the lateral malleolus and the base of the fifth metatarsal, reveal the long and short tendon tendons of the humerus, cut off as far as possible, and free the tendon to the proximal side. To the posterior margin of the lateral malleolus, the distal end of the long iliac crest is sutured to the tendon sheath. A second longitudinal incision was made on the surface of the tendon at the lower third of the calf junction, about 5 cm long. The tendon is extracted from the tendon sheath, taking care to avoid destroying the starting point of the short bone of the tibia. 2. The location of the new stop point of the patella tendon depends on the severity of the deformity and the existing muscle strength. When the long extensor muscle still functions and wants to be transposed to the first metatarsal neck, the iliac tendon should be translocated to the lateral cuneiform bone. When no other functional dorsiflexors are available, the iliac crest tendon should be used. Place it in the middle wedge. 3. In addition, a longitudinal incision is made to remove the long extensor tendon of the toe, revealing the wedge bone (middle or lateral), and the "ten" or "H" shaped incision is made on the periosteum. The periosteal flap is picked up and a hole is drilled in the bone to be large enough to receive the tendon. Pull the two tendons under the calf cruciate ligament into the incision, suture them laterally, and pass them through the bone hole in an isometric manner, either by folding them back and suturing themselves, or by using a platform staple to securely fix them. On the bone. Another method is to drill a bone hole in the middle wedge bone, pass the tendon through the bone hole, and fix it to the sole of the foot with a button. 4. When the toe has obvious claw-shaped malformation, the long extensor tendon should be transposed to the first metatarsal neck, and the interphalangeal joint should be ligated with the tendon and long extensor tendon, and the remaining 4 toe residual claws. Malformations are usually not obvious.
