described a 34-year-old female with bilateral ligamentous aplasia treated bilaterally with ACL reconstruction with patellar autograft, anteroexternal
Lemaire ligamentoplasty, internal ligamentoplasty with lateral ligament tensioning, posterointernal ligamentoplasty, and tibial osteotomy to correct an extension defect.
The first upper molar has the typical enlarged anteroexternal
cusp and a reduced associated cristid, characters identified as synapomorphies of the A.
Both Lamini and Camelini share several characteristics, but Lamini is distinguished from Camelini by configuration of the anterior end of the nasals and presence of an anteroexternal
style (llama buttress) on lower molars (Harrison, 1979).
Examination revealed a hard, painless lump in the anteroexternal region of the right elbow, which was not reducible in flexion-extension or in pronation-supination.
Based on this rare case, we can state that the development of a solitary, anteroexternal osteochondroma in the proximal metaphysis of the ulna leads to dislocation of the radial head and prevents anatomic development of the physiological ulnar curvature.
1 A) with straight, wide, deep cervical groove and not reaching lateral margin; anterolateral margin with depression just posterior to anteroexternal
orbital angle; lateral margin with approximately 12 papilliform teeth; postfrontal lobes small, oval and delimited anteriorly by 2 depression; median groove shallow; front lacking distinct upper border, frontal area sloping downward, bilobed in dorsal view, lower margin strongly sinuous in frontal view; upper and lower orbital margins each fringed with tubercles (Fig.
