Angular Limb Deformity Correction

Question 1

Knapp, Vet Surg, 2016:

1. Chondrodystrophic dogs were more likely to have uniapical or biapical deformities and by how much?
2. Was the incidence of subjective torsion higher in chondrodystrophic or non-chondrodystrophic dogs?
3. What are the odds of having radiographic elbow disease in limbs with torsion vs limbs without torsion?

Answer 1

Knapp, Vet Surg, 2016:

1. Chondrodystrophic dogs were 3 times more likely to have a biapical vs uniapical deformity, and these deformities were almost always partially compensated
2. Incidence of subjective torsion was higher in chondrodystrophic dogs
3. Odds of having radiographic elbow disease was 4.5 times higher in limbs with torsion

Question 2

Franklin, Vet Surg, 2017:

1. Effect(s) of oblique plane inclined osteotomies?
2. Radial torsion values vs radial rotation?

Answer 2

Franklin, Vet Surg, 2017:

1. Oblique planed inclined osteotomies improved limb alignment and resulted in osseous union and full or acceptable function
2. Radial rotation is often greater than radial torsion and the use of radial torsion values alone may result in under-correction of radial rotation

Question 3

Kroner, Vet Surg, 2017:
Assessment of radial torsion using CT

1. Interobserver reliability for uniapical vs biapical deformities?
2. Intraobserver reliability for uniapical vs biapical deformities?
3. What % of uniapical and biapical deformity limbs had evidence of lateral radial head subluxation

Answer 3

Kroner, Vet Surg, 2017:

1. Interobserver reliability was good for uniapical limbs and excellent for biapical limbs
2. Intraobserver reliability was excellent for both uniapical and biapical limbs
3. 20% of the uniapical and 40% of the biapical limbs had evidence of lateral radial head subluxation

Question 4

Cooley, Vet Surg, 2018:

1. What % of the dogs with uniapical and biapical deformities were chondrodystrophic?
2. Overall limb rotation in normal dogs?

Answer 4

Cooley, Vet Surg, 2018:

1. 0% of the uniapical dogs and 90% of the biapical dogs were chondrodystrophic
2. Overall limb rotation in normal dogs is 35 degrees

Question 5

Worth, VCOT, 2019:
Computer-assisted surgery using 3D printed saw guides

What % healed without complications?

Answer 5

Worth, VCOT, 2019:

71% healed without complications
