Fig1
There was focal increased radiopharmaceutical uptake in the region of the right fore distal humerus (Fig. 1a and b) Due to the absence of a cranial craniocaudal scintigraphic view, this could not be localized further on the basis of the scintigraphic findings.
Mediolateral radiographic views of the elbow of a 3 year old thoroughbred gelding with lateral partial avulsion of the ulnaris lateralis and enthesiopathy of the lateral epicondyle of the humerus. No radiographic abnormalities were identified

Fig3
Ultrasonographic image of the lateral aspect of the elbow of a 3 year old thoroughbred gelding. Longitudinal and transverse images of the lateral epicondyle of the right elbow. There is an irregular bone surface and remodelling of the lateral epicondyle of the right humerus at the site of the origin of the ulnaris lateralis tendon. The fibre pattern of the ulnaris lateralis tendon was disrupted on the longitudinal view, with a discrete hypo-echoic region at the site of origin onto the lateral epicondyle

Fig4
Transverse and longitudinal views of the lateral aspect of the elbow showed an irregular bone surface and remodelling of the lateral epicondyle of the right humerus at the site of the origin of the ulnaris lateralis tendon. The fibre pattern of the ulnaris lateralis tendon was disrupted on the longitudinal view, with a discrete hypo-echoic region at the site of origin onto the lateral epicondyle (Fig. 4).

T-ulnaris lateralis tendon; LEC-lateral epicondyle of the humerus. b Transverse ultrasonogram of the origin of the ulnaris lateralis on the lateral epicondyle of the humerus, T-Ulnaris lateralis tendon; LEC lateral epicondyle of the humerus. c Longitudinal ultrasonogram of the origin of the lateral collateral ligament of the elbow.

Fig5
A reference ultrasound image (obtained from a different 3yo thoroughbred horse) of the ulnaris lateralis origin on the lateral epicondyle is shown in fig. 5a and b, in addition a reference image of the origin of the collateral ligament of the elbow is shown in Fig. 5c.
