Following the incident, difficulty in walking is evident, and major swelling normally ensues quickly following the incident. Thereafter, discoloration is frequent as a consequence of simultaneous rupturing of blood vessels. Additionally edema fluid leaks into the tissues over the initial 24 hours. X-rays need to be taken, even though sprains are usually negative. However, fractures must be ruled out.
Ligaments are like rope, consisting of many strands or fibers.
The sprain can result in tearing of several or all of the strands. Resulting weakness and recovery is a by-product of the severity of the initial sprain. Heeling of the ligaments normally takes about 6 weeks, although swelling can persist for several months. A total tear may involve surgery. An incision is made on the side of the ankle and a portion of the a tendon called the peroneus brevis is used to reconstruct the lateral ligaments.
