Extensor Tendons
Injuries to the distal end of the extensor mechanism in Zone I are also known as_________
What is a mallet finger?
This flexor tendon zone has been described as "no man's land"
What is Zone ll?
In this stage of wound healing edema is liquid, soft, and easy to mobilize
What is the Inflammatory Stage?
TAM of a digit is calculated by this formula
What is degrees of flexion of the MP, PIP, and DIP joints minus any extension lag of the MP,PIP, and DIP joints?
This orthotic is used for flexor tendon repairs
What is a DBS (dorsal blocking splint)?
The first dorsal compartment commonly released for deQuervain's contains these tendons
What are the APL (abductor pollicis longus) and the EPB (extensor pollicis brevis)
The FDP runs through the split of the FDS which creates a tendinous structure at the level of the PIP joint
What is Camper’s chiasm?
The theory behind using this modality to reduce edema is to provide vasoconstriction, reduce metabolic rate, and reduce arteriolar blood flow thereby reducing membrane permeability and capillary infiltration.
What is cold?
Patient education for orthotics includes these four elements
What are?
Wear schedule, donning and doffing, precautions, care of the orthotic
These two digits have independent extensors in addition to the EDC
What are the index EIP (extensor indicis proprius) and the small EDM (extensor digit minimi)?
Fibrous bands anchoring tendons to underlying structures.
What are pulleys?
These three treatment techniques are commonly used to help reduce and manage edema
What are elevation, active motion and compression?
If untreated, Zone III extensor tendon injuries lead to this deformity due to the disruption of the central slip from the base of the middle phalanx
What is a boutonniere deformity?
This phase of wound healing lasts up to a year and is characterized by collagen cross linking and replacement of disorganized collagen by organized collagen
What is the Remodeling phase?
At the level of the wrist, the extensor tendons are covered by this synovial lined sheath
What is the extensor retinaculum?
