Intervertebral bridging ossifications increase the risk of intravertebral cleft formation following a XXXX .

PURPOSE: To determine whether the presence of intervertebral bridging ossifications is associated with intravertebral cleft (IVC) formation following a @entity3814 ( @entity3814 ). METHODS: @entity1 with a @entity3814 who received conservative treatment for a minimum of 3  months were recruited over a 3-year period. Baseline radiographs obtained within a month of onset were compared between 50 @entity1 who developed an IVC at 3-month follow-up (IVC group) and 100 @entity1 without an IVC (control group). Intervertebral bridging ossification was defined as complete bridging of the intervertebral space by ossification. The presence of bridging ossification was assessed at each intervertebral level from T9/10 to L5/S. In addition to the absolute levels of bridging ossifications, the level relative to a fresh @entity3814 was recorded. RESULT: The incidence of bridging ossification at levels T9/10 and @entity3138 was significantly higher in the IVC group than in the control group. IVC group @entity1 showed a significantly higher incidence of bridging ossification at the second proximal intervertebral segment than those in the control group. IVC group @entity1 also had a significantly greater sagittal wedge angle and a greater local kyphosis angle than control group @entity1 . CONCLUSION: A fresh @entity3814 with bridging ossification at the second proximal intervertebral level is associated with increased risk of IVC formation. Careful observation and strict conservative treatment are recommended in such cases.
