TMT joints was visible in 20% of successful CD injections.
MAIN LIMITATIONS:
Despite specific requests to do so, we were unable to
standardise the injection technique across all operators.
CONCLUSIONS:
The accuracy of injecting the TMT and CD joints of se-
dated horses was 96 and 42%, respectively. The CD joint
was frequently missed with contrast medium being
placed in the periarticular tissues. These data support
the clinical impression of the difficulty of injecting the
CD joint and suggests that practitioners should utilise
ancillary methods, such as radiographs, to ensure prop-
er needle placement.

Abstract
OBJECTIVE:
To describe the results of screw placement through
subchondral lucencies (SCL) of the proximal radius in 8
horses.
STUDY DESIGN:
Retrospective clinical study.
ANIMALS:
Horses with cubital SCL causing lameness (n=8).
METHODS:
Medical record review and clinical follow-up.
RESULTS:
Eight horses with SCL in the proximal radius causing
lameness were treated with a screw placed across the
lucency. The horses range in age from 1 to 20 years. In
4 of 8 horses, the lameness had been intermittently se-
vere (apparent at the walk). Lameness was isolated to
the cubital joint by intra-articular anesthesia in 5 horses
and diagnosed radiographically in all 8. All horses had a
4.5 mm cortical bone screw placed from medial to lat-
eral (6 lag, 2 neutral) across the SCL using fluoroscopic
or radiographic control. Postoperative care included
stall confinement with hand walking for 30-60 days, fol-
lowed by an additional 30-60 days of pasture turnout.
Radiographic SCL healing (reduction in SCL size) was
demonstrated at 3-4 months after surgery in all horses,
and 7/8 horses (87.5%) were used as intended (4 perfor-
mance, 3 pasture turn-out) within 6 months. Lameness
in the remaining horse improved initially (dressage) but
returned.
CONCLUSIONS:
A screw placed through the SCL of the proximal-medial
radius was effective in reducing or resolving lameness
associated with the elbow joint in 7/8 horses (88%).
Screw placement in the proximal radius should be
considered for horses with lameness caused by an SCL
when a quick return to exercise is desired or conserva-
tive therapy is ineffective.
