Ankle Injuries During Spring Running: Common Musculoskeletal Disorders and Effective Immobilization

With the arrival of spring, outdoor running and other sports become more frequent, leading to a higher incidence of ankle injuries. Among musculoskeletal disorders, sprains and ligament damage are some of the most common problems experienced by runners and active individuals.^{[1][2][3][4][5][6][7][8]}

Common Ankle Musculoskeletal Disorders in Runners

• Ankle Sprain
  An ankle sprain occurs when ligaments are stretched or partially torn due to twisting or rolling the ankle. This is the most frequent ankle injury, often affecting the lateral ligaments (such as the anterior talofibular ligament and calcaneofibular ligament). Symptoms include pain, swelling, bruising, and restricted range of motion. Severe sprains may result in complete ligament rupture and joint instability.^{[1][2][4][5][6]}
• Ligament Rupture
  A severe twist or roll of the ankle can cause complete rupture of the ligaments. Repeated sprains may lead to chronic instability if not properly managed.^[1][2][6]
• Muscle Strain
  Sudden changes in direction or landing from a jump can overload the muscles around the ankle, resulting in micro-tears or strains.^[5][6][8]
• Tendinitis
  Repetitive stress on tendons around the ankle, such as the Achilles tendon, can lead to inflammation and pain (tendinitis).^[4][5][6][7]
• Osteochondral Injury
  A significant twist of the ankle can damage the cartilage surface of the joint, leading to pain and swelling.^[6]
• Chronic Ankle Instability
  Repeated sprains can loosen the ligaments, resulting in a chronically unstable ankle that is prone to further injury.^[2][6]

Main Causes

• Running on uneven surfaces, sudden changes in direction, insufficient warm-up, previous injury history, and ill-fitting shoes are common causes.^{[1][4][5][6][8]}
• In particular, excessive inward (medial) rolling of the ankle is a major cause of ligament injuries.^[1][5][6]

Ligament and Muscle Immobilization & Management

• Initial Treatment:
  The RICE protocol (Rest, Ice, Compression, Elevation) is the primary approach during the first 24–48 hours after injury.^[1][2][5]
• Early Functional Immobilization:
  Rather than prolonged casting, early mobilization combined with appropriate immobilization and rehabilitation exercises is recommended for faster recovery and to prevent recurrence.^[2][3][5][6]
• Use of Braces/Splints:
  Functional splints or short leg splints that stabilize the ankle ligaments and muscles, while allowing for changes in swelling, are recommended for effective support and recovery.^[3][6][8]

3. Gently dry the splint, then mold it to fit the injured area.
4. Secure the splint with the provided Velcro straps.
5. If swelling changes, the splint can be remolded for a better fit.

Safety Instructions

• Always read the product label and instructions before use.
• Significant deformation of the splint may impair its function.
• Avoid applying excessive heat or force to the product.
• Do not reuse on multiple patients.
• Monitor swelling and adjust as needed for comfort and effectiveness.
