An Achilles tendon rupture is usually obvious when it happens. It is a potential serious injury because of the rehabilitation that is needed. Treatment is generally with a walking brace or surgery.
Urgent or prompt medical attention is generally needed so a decision can be made as to which option is the best for each person and the rehab can be started.
In the interim the Achilles tendon rupture can be splinted in the field before getting medical attention:
Help the person sit or lie down in a comfortable position. Elevating the leg can help reduce swelling.
Gently straighten the leg and keep the foot and ankle in a neutral position, neither pointed downward nor upward. You can use a rigid splint or any firm object that can support the lower leg, such as a rolled-up newspaper, a wooden plank, or a metal strip.
Place some soft padding, such as towels or clothing, around the leg before applying the splint. This can help provide comfort and prevent pressure points.
Use bandages, cloth strips, or any available material to secure the splint in place. Wrap the material around the leg and the splint, taking care not to wrap it too tightly, as this can impede blood circulation. Secure the bandages with knots or tape.
Then, get them to medical care for a correct diagnosis and treatment decision.
