trochlear notch
semicircular notch in the proximal extremity of the ulna, articulates with the trochlea of the humerus, overhung by the 'beak' of the ulna's anconeal process.
trochlear orbit
a flat piece of cartilage, or loop of fibrous tissue, embedded in the dorso-medial wall of the orbit close to the edge of the orbit; acts as a pulley for the dorsal oblique muscle.
trochlear talus
the proximal articular surface on the talus, articulates with the tibia.

Perhaps most importantly though, the 3-D models helped Koh improve patient care: Post-operative X-rays of the woman's repaired knee showed a healed osteotomy with restoration of near-normal trochlear anatomy and an MPFL graft.
However, as the knee flexes and the MPFL becomes more relaxed, the trochlea becomes the primary stabilizer of the patellofemoral joint, and trochlear dysplasia has been shown to be present in up to 85% of patients with recurrent patellar instability.
Sunrise views can also show a narrowed joint space, as well as the presence of trochlear dysplasia, patellar tilt, or subluxation.
The command for vertical saccades projects directly to the oculomotor and trochlear nuclei.
Dr Simon Grant BSc PhD Oculomotor, trochlear or abducens nerve palsies are relatively common, but pose challenges for clinical management.
Examination revealed right-sided ptosis and a mild right oculomotor (III) and trochlear (IV) nerve palsy that was most noticeable on medial gaze.
40-42) Over a 10 year period, a large series of 365 cases noted that the majority of allografts are performed for lesions of the medial (36%) and lateral (18%) femoral condyles, whereas the patellofemoral compartment (patellar, trochlear and bipolar) accounted for 18%.
15) An audible click on attempting elevation in adduction, followed by an improvement in the eye movement, indicates that the aetiology is an obstruction to the movement of the muscle through the trochlear pulley.
The presentation, titled "Treatment of Osteochondral Autograft Donor Sites Using Porous, Biodegradable Scaffold," concluded that critical size cylindrical defects made in the trochlear groove and medial femoral condyle of skeletally mature goats filled with porous, polymeric implants healed with subchondral bone and overlying hyaline cartilage.
This presented in a number of ways, including an increased size of the medial trochlea, increased thickness of medial patellar or trochlear cartilage, and relatively flat trochlea in the setting of a Wiberg type 3 or Hunter's cap patella.
Indications for ACI include symptomatic, large, full-thickness chondral lesions located on the femoral condyles or the trochlear groove.
Diabetic patients presenting to an optometrist with diplopia may have a mononeuropathy of the oculomotor (3rd), trochlear (4th) or abducens (6th) cranial nerve.
