Angular limb deformities/flexural deformities Flashcards
What are angular limb deformities?
Postural deformities in frontal plane of the limbs with lateral or medial deviation
What are the terms for lateral vs. medial deviation of the limbs?
Lateral=valgus Medial=varus
What are causes of angular limb deformity?
Periarticular laxity Incomplete ossification of carpal bones Hypothyroidism Limb conformation Twins
What are the regions for angular limb deformity formation?
Carpus Tarsus Metacarpo/metatarsophalangeal joints
What are the two locations for angular limb deformity?
Growth plate Joint space
What shoes are used to conservatively treat angular limb deformity in horses?
Dalmer shoes
What is the surgical procedure to correct angular limb deformity by providing growth acceleration?
Hemicircumferential periosteal transection and elevation “Periosteal Stripping”
What is the surgical procedure correcting angular limb deformities by providing growth retardation?
Temporary transphyseal bridging
What is the surgical treatment for the most severe form of angular limb deformity used in fully grown equine?
Corrective osteotomy “closing wedge ostectomy”
What is the definition of flexural deformities?
Hyperflexion of a limb that results from disparity in length of musculotendinous unit relative to bone length “Contracted tendons”
What is the characteristic appearance of a flexural deformity?
Elevated toe from the ground with a sinking fetlock
Which tissues are involved with flexural deformities?
SDF, DDF, suspensory ligament, joint capsule, combination
WHat are conservative treatments for flexural deformity?
Exercise, shoeing, splints, oxytetracycline, cast
How does oxytetracycline work as a conservative treatment for flexural deformities?
Binds to calcium leading to muscle relaxation
What is the surgical treatment for bilateral contracted tendons?
Digital flexor tenotomy Midcarpal incision on the FLEXED leg
