Final answer:
A 90/90 flexion sling is used in puppies to support healing limbs by keeping them at a 90-degree angle at the hip and knee, promoting proper joint alignment and helping to prevent contractures.
Step-by-step explanation:
The function of a 90/90 flexion sling in puppies is primarily to aid in the recovery process after injuries or surgery that affects their limbs. It serves as a supportive device designed to maintain the legs of a puppy in an optimal healing position, specifically at a 90-degree angle in both the hip and knee joints. By ensuring the limbs are kept in this position, the sling promotes proper joint alignment and stabilization during the healing process, which is critical for the puppy's future mobility and overall joint health. Additionally, a 90/90 flexion sling can also help in preventing the development of contractures, which are permanent tightenings of the muscles, tendons, or skin that can severely limit joint movement.
