PURPOSE: To measure the projection of probably the most anterior line of the spinal canal on lateral radiographs of the vertebra (C3-L5) and consider the efficacy of the security line (SL) in stopping intraspinal cement leakage in percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP).
MATERIALS AND METHODS: Fifteen grownup dry-bone backbone specimens have been analyzed. The projection of the SL was seen on lateral radiographs. The gap between the SL and the posterior vertebral physique line (PVBL) was measured. Two teams of sufferers have been handled by PKP, and cement injection was stopped both earlier than the PBVL (group 1) or earlier than the SL (group 2) underneath lateral fluoroscopy. The speed of cement leakage was in contrast between the 2 teams.
RESULTS: The most important distance between the SL and PVBL was at L1 (5.22 ± zero.62 mm). From L1 to L5, the space decreased progressively to 1.05 ± zero.64 mm. Related variation was additionally noticed from L1 to T1 (zero.19 ± zero.18 mm). The postoperative computed tomography scan was extra delicate and correct in detecting intraspinal leakage than radiography in group 1 (p = zero.000); nevertheless, there was no vital distinction in sensitivity or accuracy between strategies in group 2 (p = zero.063). The speed of intraspinal cement leakage was considerably larger in group 1 than group 2 (p = zero.000).
CONCLUSIONS: The operator ought to steadily verify to make sure that cement injection has stopped upon reaching the SL. Surgeons could profit from this quantitative anatomical examine of PKP and PVP.
