An independent samples t-test was used for the remaining MOCART variables (subchondral lamina, subchondral bone, adhesions, effusion).
The results demonstrate the benefits of composite DBM and osteoconductive material with a lamina local bone graft for multi-segment lumbar spine fusion.
Similarly, at 24 months following treatment of talus osteochondral defects, Giannini and colleagues [ 91] reported cartilage surface intactness in 40%, iso-intense cartilage tissue in 70%, but subchondral lamina and bone intactness in only 10%and35%5%, respectively.
However, such favorable results were not reflected by the MRI data, which showed subchondral lamina and bone changes in all five cases, and intralesional osteophytes in three at 2 year follow-up.
Specifically, 29 months following treatment of femoral condyle osteochondral defects, Buda and colleagues [ 81] noted cartilage surface intactness in 70%, iso-intense cartilage tissue in 65%, but subchondral lamina and bone intactness in only 30% of participants on MRI.
In the procedure of laminoplasty, the spinal canal is decompressed by rotatory elevation of the laminae, and bone grafts from the spinous process and posterior iliac bone are placed on the surface of the operated laminae.
After the laminae were exposed, bone from the inferior edge of the superior lamina as well as the superior edge of the inferior lamina was removed.
In this case, both columns were intact, but there was a deep impaction with dislocation of the posteroinferior articular portion and comminution of quadrilateral lamina and ischiatic bone fracture.
Hydroxyapatite (HA) is a commonly used synthetic biomaterial which has some properties akin to the tooth and bone lamina used in OOKP surgery.
