Contractures after a burn injury are reversible.

Choice A rationale Contractures are not reversible in the sense that they can be fully restored to pre-injury function without intervention. They are a permanent shortening of muscle, skin, and connective tissue, which can severely limit joint mobility. The extensive scarring and fibrous tissue formation physically restricts movement and necessitates aggressive, long-term intervention to manage. Choice B rationale Contractures, a pathological shortening of tissue, are considered irreversible without surgical and physical therapy interventions. The physiological basis is the formation of scar tissue, which is a dense, non-elastic collagen matrix that replaces healthy tissue after deep burns. This scar tissue physically restricts joint movement and cannot be spontaneously reversed. Choice C rationale While physical therapy and occupational therapy are essential for managing and minimizing contractures, they do not make them "sometimes reversible.”. Therapy focuses on prevention through splinting, positioning, and range-of-motion exercises, as well as on improving function and mobility. Established contractures often require surgical release, followed by intensive therapy, but the underlying scar tissue remains. Choice D rationale Contractures are not simply reversible in minor cases. Even in less severe burns, if they are deep enough to cause significant scarring, they can lead to contractures. The degree of the burn (e.g., full-thickness or deep partial-thickness) and the location, not the overall size, are the determining factors in whether contractures are likely to form.
