Orthosis Application and Functionality

The video demonstrates the use of an Antica orthosis made from Orit strips. It explains how to prepare the strips by heating them in water, apply them to the patient's hand to support the mCP joints, and secure them with Velcro. The orthosis helps in repositioning the mCP joints in flexion and extending the PIP joints, preventing hyperextension while allowing full finger flexion.

What is the primary purpose of the Antica orthosis?

• To enhance grip strength

• To immobilize the wrist

• To reposition the mCP joints in flexion

• To support the elbow

What is the recommended temperature for activating the thermoplastic material?

• 50° C or 122° F

• 70° C or 158° F

• 60° C or 140° F

• 65° C or 149° F

How should the patient's fingers be positioned during the application of the orthosis?

• Slightly bent

• Fully extended

• In the intrinsic plus position

• In a fist

Where should the middle section of the orthosis strip be placed on the patient?

• Over the wrist

• Over the proximal phalanges

• Over the distal phalanges

• Over the metacarpals

What is the purpose of molding the material into the palm?

• To reduce weight

• To improve aesthetics

• To support the arch of the palm

• To increase flexibility

What should be done after the orthosis material has cooled?

• Remove it immediately

• Trim the strips and round the corners

• Reheat the material

• Apply a second layer

How is the orthosis secured on the hand?

• With metal clips

• With adhesive tape

• With rubber bands

• With Velcro straps

What should be checked to ensure the orthosis is effective?

• The weight of the orthosis

• The prevention of mCP joint hyperextension

• The patient's comfort

• The color of the material

What movement does the orthosis allow while preventing hyperextension?

• Wrist rotation

• Thumb opposition

• Full finger flexion

• Elbow extension
