Which of the following is not part of the multifactorial complex implicated in development of angular limb deformities in foals?
- Abnormal fetal limb positioning
- Placentitis
- Hypoplasia of the proximal sesamoid bones
- Growth-plate trauma
Hypoplasia of the proximal sesamoid bones
Which statement regarding diagnosis of angular limb deformities in foals is true?
- Regardless of the degree and location of the defor- mity, all foals should have their limbs radiographed at the initial examination.
- The limb can usually be manually straightened in foals with asymmetric physeal or epiphyseal growth.
- The limb can usually be manually straightened in foals with hypoplasia of the carpal bones.
- Radiography is useful in determining the degree of rotational deformity.
The limb can usually be manually straightened in foals with hypoplasia of the carpal bones.
Which statement regarding the diagnostic workup in foals with tarsal angular limb deformi- ties is correct?
- A dorsoplantar radiographic view is especially useful in identifying tarsal bone hypoplasia.
- A lateromedial radiographic view is especially useful in identifying tarsal bone hypoplasia.
- Clinicians should rely heavily on a dorsoplantar ra- diographic view for exact identification and evaluation of the location and degree of tarsal angular limb deformities.
- Concurrent rotational deformities are best identified using radiography.
A lateromedial radiographic view is especially useful in identifying tarsal bone hypoplasia
Which of the following is the most likely cause of carpal angular deformities in newborn foals?
- Asymmetric growth at the distal radial growth plate
- Periarticular laxity
- Delayed ossification of the epiphysis
- Asymmetric growth at the distal radial growth plate and the epiphyseal growth cartilage
Periarticular laxity
Which statement regarding congenital hypothyroidism is correct?
- It has been implicated as a cause of uneven physeal growth.
- It has been implicated as a cause of delayed ossification of the carpal and tarsal cuboidal bones.
- It has been implicated as a cause of delayed epiphyseal ossification.
- It is often associated with abnormal fetal limb posi- tioning.
It has been implicated as a cause of delayed ossification of the carpal and tarsal cuboidal bones.
Foals with tarsal bone hypoplasia tend to present with
- valgus deformity
- varus deformity
- valgus deformity and straight-hocked appearance
- valgus deformity and sickle-hocked appearance
valgus deformity and sickle-hocked appearance
Which statement regarding physical examination of foals with angular limb deformities is true?
- Angular limb deformities are often associated with some degree of lameness in the affected limb(s)
- Angular limb deformities are normally associated with heat, pain, and swelling at the site of the deformity
- In most cases, foals with angular limb deformities are not lame
- a and b
In most cases, foals with angular limb deformities are not lame
Which statement regarding foals with cuboidal bone hypoplasia is correct?
- If left untreated, cuboidal bone hypoplasia results in a manually irreducible deformity within 2 weeks
- If left untreated, cuboidal bone hypoplasia results in a manually irreducible deformity within 2 days
- Manual reducibility of this condition is not time dependent
- This condition is never manually reducible
If left untreated, cuboidal bone hypoplasia results in a manually irreducible deformity within 2 weeks
Angular limb deformities most often originate within the carpal, tarsal, __________ joint regions
- or distal interphalangeal
- or proximal interphalangeal
- or metacarpo- or metatarsophalangeal
- distal interphalangeal, or metacarpo- or metatarsophalangeal
or metacarpo- or metatarsophalangeal
To avoid development of a contracted foot in a foal, glue-on shoes should not be left on for longer than:
2 weeks
To allow rapid growth in young foals, tube casts should be changed at __________ intervals
10-14 day
Corrective ostectomy or osteotomy is
- preferred in treating tarsal bone hypoplasia
- preferred in treating severe carpal or tarsal bone hypoplasia
- generally performed before cessation of physeal growth
- generally performed after cessation of physeal growth
generally performed after cessation of physeal growth
Which statement regarding tFeatment of foals with carpal bone hypoplasia is correct?
- Foals with carpal bone hypoplasia often require surgical treatment after an initial period of splint bandaging
- Foals with valgus deformities caused by carpal bone hypoplasia should be treated with confinement and by applying a glue-on shoe with extension to the inside
- Foals with valgus deformities caused by carpal bone hypoplasia should be treated with confinement and by applying a glue-on shoe with extension to the outside
- Foals with carpal bone hypoplasia should be treated with splint bandaging or tube casting.
Foals with carpal bone hypoplasia should be treated with splint bandaging or tube casting.
A 6-week-old foal with a significant varus defor- mity caused by asymmetric grvwth at the distal metatar•I growth plate in the left hindlimb is best treated with
- splint bandaging and confinement
- confinement
- corrective trimming and, possibly, shoeing as well as confinement
- surgery, corrective trimming, and, possibly, shoeing as well as confinement
corrective trimming and, possibly, shoeing as well as confinement
Potential complications of periosteal transection and stripping for treatment of angular limb deformities includes all of the following except:
- Incisional infection
- Incomplete correction
- Overcorrection
- Bony exostoses
- Incisional dehiscence
Overcorrection
Concerning hemicircimferential transaction/periosteal stripping for treatment of angular lib deformity, which is LEAST accurate?
- The surgical procedure is performed on the concave aspect of the affected limb
- Periosteal stripping is considered to be a growth retardation procedure
- The duration of its effect is approximately 60 days
- Over correction of an angular limb deformity des not occur with this surgical procedure
- Surgical implants (screws, cerclage wire, etc) are not used in this surgical procedure
Periosteal stripping is considered to be a growth retardation procedure
Postoperative treatment of foals using HCPTE includes:
- free pasture exerdse because it tends to increase the rate of correction
- confinement
- splint bandaging
- none of the above
confinement
