What injuries can cause ankle pain?
Ankle sprains and fractures
Ankle sprains are one of the most common musculoskeletal
injuries. Sprains are injuries to the ligaments of the ankle, causing
them to partially or completely tear as a result of sudden stretching.
They can occur on either or both of the inner and outer portions
of the ankle joint. Ankle sprains more commonly happen when there
is a preexisting muscle weakness in the ankle area or a history
of previous ankle injuries. The typical injury occurs when the
ankle is suddenly "twisted" in a sports activity or
by stepping off an uneven surface. The pain is initially severe
and can be associated with a "popping" sensation. Immediate
swelling over the area of injury often occurs as the injured blood
vessels leak fluid into the local tissue. Examination of the area
may cause severe pain when the ankle is moved. The degree of pain
may not necessarily indicate the degree of damage to the ligament(s).
Ligament injuries are often graded from I to III, ranging from
partial to complete tears. Partial tears retain some ankle stability,
whereas complete tears lose stability because the strapping ligaments
no longer brace the ankle joint. After an examination, significant
ankle sprains are commonly evaluated with an X-ray. X-rays
can determine whether there is an accompanying break (fracture)
of the bone.
Acute ankle sprains are initially treated with ice, rest, and limiting the amount of walking and weight-bearing on the injured ankle. The leg can be elevated to reduce swelling, and crutches are often recommended to avoid further trauma to the injured ligaments. Anti-inflammatory medications can be given to reduce local inflammation. Ice packs help decrease further swelling of the area and can reduce pain. Patients with severe injuries are placed in immobilization casts. Surgical repair of grade III injuries is considered, especially for those patients contemplating future athletic participation. Physical therapy programs are part of the rehabilitation process, incorporating strengthening exercises of the lower leg muscles. Broken ankles (fractures) can accompany ankle sprains or occur without sprains. Fractures are repaired with casting to immobilize the bone for healing. Depending on the severity, fractures can require orthopedic casting, surgical procedures including pinning, and open repair of the fractured bone.
Tendinitis
Tendinitis (also referred to as tendonitis) is an inflammation of the tendon. Tendinitis of the ankle can involve the Achilles
tendon, the posterior tibial tendon, or the peroneal tendon. This condition usually
results from trauma, such as from sudden injury in sports or overuse injury as from running but can result from underlying inflammatory
diseases or illnesses such as reactive arthritis (formerly called Reiter's syndrome), rheumatoid arthritis,
and ankylosing spondylitis. All forms of tendinitis cause pain,
swelling, and tenderness in the tendon area involved. The onset
may be rapid, such as with an athletic injury. Immediate treatment of tendinitis
involves immobilizing the area, elevation, and limiting weight-bearing, applying
ice, and using nonsteroidal anti-inflammatory drugs (NSAIDs) to
decrease inflammation. NSAIDs such as naproxen (Naprosyn) or
ketoprofen (Orudis) are commonly used for this purpose. More severe inflammation
can require orthopedic casting. Athletic participation should
be limited when the tendon is still inflamed, as there is a
significant
risk of rupturing or tearing the tendon, especially in the Achilles
area, with continued athletic activity. Achilles
tendon more frequently occurs in patients who have had previous
Achilles tendon inflammation. When the Achilles tendon ruptures, it usually
requires orthopedic surgical repair.
