Imaging Features and Management of Stress, Atypical, and Pathologic Fractures. Thus, it appears most patients with what has been called spontaneous osteonecrosis of the knee actually have subchondral insufficiency fractures. 4. Intraoperative photos. The answer appears to be "maybe" as non-weight-bearing conservative therapy has not consistently prevented progression of the disease. Hatanaka H, Yamamoto T, Motomura G, Sonoda K, Iwamoto Y. Skeletal Radiol. In general, they are seen in the elderly, more frequently in women 2. A subchondral insufficiency fracture (SIF) of the femoral head is a recently proposed concept, which needs to be differentiated from osteonecrosis. MRI is used to confirm the presence of and evaluate subchondral signal ( Fig 1 ). Further progression of osteonecrosis at the lateral femoral condyle with a displaced curvilinear bony lesion was noted (, At 2weeks after the hospital admission, a left UKA for the lateral compartment was performed. They are most often seen in the setting of osteoporosis, although any process which weakens bone is a risk factor. sharing sensitive information, make sure youre on a federal - , , ? All 10 complications occurred between 2 and 9 months after injection: six (60%) in the hip and four (40%) in the knee.

Restoration of the trabecular structure was eventually observed without obvious collapse of the articular surface (Figure 5E, 5F, 5K, 5L). The lesion, measuring 722217 mm on magnetic resonance imaging (MRI), appeared as a tumor with clear margins in the popliteus muscle. Post-arthroscopic osteonecrosis of the medial tibial plateau: a case series. However, as SIFK is predominantly localized to a single compartment, and in view of the favorable outcome of treating unicompartmental osteoarthritis with UKA, there has been growing interest in treating SIFK with UKA as an alternative to TKA. While prophylactic intramedullary nailing is a common approach for preventing radiation-associated fractures, especially in the diaphysis of long bones [4], it has been suggested that prophylactic nailing should not be routinely performed because the risk of fracture is low.

In addition, we must be careful because deep infection rates up to 20% after surgery have been reported for radiation-associated fractures in some series [5,8]. Check for errors and try again. Third, is there any method of halting the progression of early subchondral changes before they progress into collapse, flattening, and loose-body formation? The causes of these lesions include contusions from trauma (with or without cruciate ligament injuries), insufficiency fractures, degenerative cartilage lesions, spontaneous CT, computed tomography. Kabra U, Subchondral insufficiency fracture of the knee. UKA appears to be a favorable surgical option, while the optimal treatment modality of SIFK of lateral femoral condyle is still uncertain due to rarity of the disease entity and paucity of high-quality evidence.
