Swelling and pain in front of and below the lateral malleolus

Introduction The swelling and pain in the anterior and posterior iliac crest are mostly due to the history of traumatic acute ligament injury of the ankle. Clinically, the patient's anterior and posterior sacral swelling and pain, local tenderness, subcutaneous ecchymosis, limited joint activity, and lameness can be found.

Cause

Causes of swelling and pain in the anterior and posterior iliac crest:

(1) Causes of the disease

Direct violence, indirect violence and muscle strain can cause injury.

(two) pathogenesis

The violence that causes acute ligament injury of the ankle is roughly divided into three types: direct violence, indirect violence, and muscle tension. Among them, indirect violence is the main factor. Most of them are inadvertently lost on uneven roads or up and down stairs. The crotch is in extreme valgus and flexion, causing excessive damage to the lateral collateral ligament. The lighter part of the inferior ligament rupture, the severe ligament can completely break the ankle joint subluxation and total dislocation. Or because of the distal valgus and external rotation of the distal end of the ankle, which directly causes damage to the medial malleolus and/or humeral ligament, most of these injuries coexist with internal hemorrhoids and/or external malleolus fractures.

Diagnosis of swelling and pain in front of the lateral malleolus:

Most of the acute ligament injuries of the ankle joint have a clear history of trauma. Clinically, the patient's anterior and posterior sacral swelling and pain, local tenderness, subcutaneous ecchymosis, limited joint activity, and lameness can be found. Pain is aggravated when the foot is passively flexed and inverted, and pain is relieved when the back is stretched and everted. When it is completely ruptured, the ankle joint is in a sacral position and the talus is displaced forward. In addition to the pain, swelling, subcutaneous bruising, and limited movement of the medial malleolus, the medial malleolus ligament may have swelling and congestion in the posterior medial malleolus; the symptoms of the inferior temporal ligament injury are similar to the above, but the pain and swelling are in The front of the ankle is not in the side.

Differential diagnosis

Differential diagnosis of swelling and pain in front of the lateral malleolus:

External humeral fractures have a significant history of trauma. It can be diagnosed without identification.
