Ottobock Malleo TriStep 50S8N Ankle Orthosis: 3-Stage Rehabilitation Support

Enhanced Description

The Ottobock Malleo TriStep 50S8N is a unique, modular ankle orthosis designed for three-stage rehabilitation following ankle injuries and surgeries. Its ingenious combination of removable modules allows for precise adjustment of support and immobilization throughout the recovery process.

Indications

• Ankle injuries (sprains, strains, subluxations)
• Chronic instability of the capsular-ligamentous apparatus
• Peroneal tendon injuries and disorders
• Inflammatory and degenerative ankle diseases (especially acute stages)
• Post-operative rehabilitation following reconstructive surgery of the ankle’s capsular-ligamentous apparatus

Application Stages

Stage 1: Exudative Phase (Days 1-3)

Treatment Goals:

Pain relief, reduction of swelling (following the PRICE protocol: Protection, Rest, Ice, Compression, Elevation).

Orthosis Application:

The Malleo TriStep is used with all modules: the plastic sole plate is attached to the base bandage. The sole plate, with an additional pronation strap, immobilizes the foot in a neutral position with slight pronation. This provides essential ankle stabilization, accelerates the resolution of inflammation, and stimulates initial repair processes. Weight-bearing is permitted only in the absence of significant pain; crutches should be used otherwise. The sole plate is worn continuously, day and night, and the orthosis cannot be used with shoes. Patient can perform pain-free movements of the foot and toes.

Stage 2: Proliferative Phase (Days 4-28)

Treatment Goals:

Gradual increase in range of motion with controlled loading, stimulation of the musculature for active joint stabilization, continued reduction of swelling, and repair of damaged tissues.

Orthosis Application:

During the day, the orthosis is used without the sole plate. Initially, the base bandage is used with red, strengthening lateral inserts and an additional semi-elastic strap applied crisscross over the bandage. These inserts protect the ligaments from supination stress. As mobility increases, the red inserts can be replaced with more flexible gray inserts. At night, to prevent re-injury, the base bandage is used with the sole plate, as the foot typically rests in supination. Rehabilitation includes therapeutic exercises under professional supervision to restore muscle strength and endurance while wearing the orthosis. Activities like walking, swimming, and cycling may be introduced towards the end of Stage 2, but only after consulting a physician.

Stage 3: Reparative Phase (Days 29-42)

Treatment Goals:

Dynamic ankle stabilization through muscle activation, restoration of range of motion and proprioception, improved coordination and balance.

Orthosis Application:

Only the soft base bandage is used without additional strengthening elements. This helps restore proprioception and provides light support. The semi-elastic strap and/or lateral inserts can be added if needed (e.g., during physical therapy). The orthosis with the sole plate is recommended at night, as in Stage 2. After Stage 3, the base bandage can continue to be used for protection and support during physical activity. The combination of modules depends on injury severity and recovery progress and is determined by the physician.

Features

• Modular design allows for adjustable fixation throughout rehabilitation.
• Components include: plastic sole plate (for maximum stabilization), base bandage, lateral inserts (two stiffness levels), and adjustable straps.
• All modules are removable and easily combined without tools.
• Lateral inserts adapt to the individual foot shape.
• Adjustable Velcro closures allow for complete opening, facilitating easy application even with significant pain.
