Chiasmapexy is used to treat empty sella syndrome, and various materials are used for the elevation of the optic chiasm. 0000001588 00000 n If a plate and screw device was used, the pseudosy-novial membrane will often form around 0000006784 00000 n xref Once the defect is fi lled, the biomembrane 0000005447 00000 n Complications of iliac crest bone graft harvesting. 1) is widely applied.2Hypertrophic nonunions show prolific callus formation.

B, preparation of the external oblique of the crest, using transosseous sutures for a very secure repair that does not affect the abductor mechanism and results in less pain and dysfunction for the patient.

As in the first case, we used an iliac crest bone graft, which halted the deterioration of visual function after chiasmapexy. In summary, when nonunions are classified, it is important to consider the underlying etiology. Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft.

Distal femur and proximal tibia bone graft donor sites. Along with the tibia, fibula, scapula, and ribs, the iliac crest is among the most common donor sites for autogenous bone. The underlying causes of nonunion vary because many factors are involved in the healing of a fracture. He is point tender over the iliac crest. Iliac crest autogenous bone grafting, although associated with donor site complications, continues to be a necessary part of the treatment of many nonunions. Physical and monetary costs associated with autogenous bone graft harvesting. 0000013034 00000 n In evaluating a nonunion, the presence of infection must be ruled out. Boffano M, Ratto N, Conti A, Pellegrino P, Rossi L, Perale G, Piana R. J Clin Med. Which of the following groups correctly identifies serologic tests that are required by the American Association of Tissue Banks (AATB) for musculoskeletal tissue allografts? Your account has been temporarily locked due to incorrect sign in attempts and will be automatically unlocked in RIA. For the upper extremity, the distal radius or proximal ulna can be alternative harvest sites. eCollection 2020. 0000008721 00000 n You are considering using a frozen allograft distal femoral condyle in your reconstruction of a massive giant-cell tumor of the knee. However, at present the iliac crest bone graft is the gold standard against which new techniques must be measured.
