Long Muscle Overview

The long palm long muscle extends from the elbow to the wrist, but 11% of modern people have lost this muscle. In the early days of human beings, it was a vital organization. Without it, hanging, climbing, and even migrating would be impossible. Surgeons like this muscle very much because it can provide a valuable source of material during transplant reconstruction surgery.

Long peroneal muscle, local core structure, superficial peroneal nerve. There are long peroneus and short peroneus and superficial peroneal nerves in the outer leg area. The superficial peroneal nerve never leaves the bone plane in this area. The superficial peroneal nerve is first on the deep side of the long peroneus longus, and then descends on the front edge of the short peroneus.

Long muscle fibula long muscle transposition for old Achilles tendon rupture

The peroneus longus muscle was cut off and the subcutaneous tunnel was used to repair the old Achilles tendon rupture. Results: Six patients were followed up for 6-12 months. The recovery of plantar flexor muscle strength reached 1 in grade III, 3 in grade IV, and 2 in grade V. Ankle dorsiflexion is 20-30, plantar flexion is 40-50. Fan An obtained good results. CONCLUSION: The transposition of the peroneus longus muscle is an effective method for the treatment of old rupture of Achilles tendon.
The peroneal long tendon is displaced to repair the Achilles tendon. It has sufficient length to embed the distal end of the long peroneal tendon in the Achilles tendon. There are fewer sutures at the suture. There is no large scar hyperplasia and adhesion after surgery, which is good for the reconstruction of the Achilles tendon to slide . The reconstructed Achilles tendon can be strengthened in growth under long-term functional stimulation. In addition, the peroneus longus tendon and Achilles tendon belong to the same tendonous tissue. There is no significant histological difference in the content of collagen fibers. The displaced peroneus longus tendon has blood supply, thus maintaining the vitality of the tendon and preventing scar degeneration. The reconstructed Achilles tendon can not only flex and flex the ankle joint, but also increase the pedaling force of the foot. This method is simple and easy to perform, and the peroneal long muscle removal has little effect on foot valgus. The short peroneal tendon of the peroneus is used to compensate. Therefore, the peroneal long muscle transposition is an effective method for treating old calcaneal rupture.

Anatomy of the long muscle neck long muscle

The cervical long muscle, also abbreviated as LC, is located in front of the cervical and upper thoracic vertebrae, and is covered by the upper and lower medial and lateral components. The pharynx and esophagus are covered by each other. The upper and lateral regions are mainly from C3-C6 transverse processes. Anterior nodule to anterior atlas nodules, the lower medial area mainly from C5-C7, T1-T3 vertebrae to C2-C4, C5-C7 transverse process anterior nodules, observed from the head to the tail found its medial to anterior The midline distance gradually increases, and the sympathetic trunks are close to C6 and C7. Therefore, the probability of damage to CST at the horizontal level increases, and the distance from the midline cannot be too far during surgery, and the occurrence of stripped LC is controlled as much as possible. Muscle and tendon tissue are components of the long cervical muscle. When bilateral contraction occurs, it represents cervical forward flexion, and unilateral cervical flexion. Demarcation points are often seen at the neck-thoracic junction. There is a tissue difference between the lower cervical spine and the thoracic spine. Most of them are muscle tissues, and the latter are tendonous tissues. This is an important sign that cannot be ignored when positioning during surgery.
