A Novel and Accurate Palpation Method for Identification of the L4 Spinous Process
نویسندگان
چکیده
The purpose of this retrospective study is to determine the reliability of a novel palpation method for identifying the L4 spinous process. The traditional method uses the iliac crests as the landmark for identifying L4 spinous process which has a reported accuracy of 50-60%. MRI scans from an earlier project “Relationship of Cavitation to Gapping Following Spinal Manipulation” (H-0906) will be used for this project; in that project, L4 spinous process was identified using a palpation procedure to differentiate the sacrum from L5 spinous process. A high signal MRI marker was placed on the L4 spinous process of participants prior to MRI. In this study, the location of the high signal marker on the resulting MRI scans will evaluated to determine if the palpation method used to identify L4 is superior to the traditional method

Vertebral level of Tuffier's line measured by ultrasonography in parturients in the lateral decubitus position
BACKGROUND It is known that Tuffier's line intersects the spine at the L4 spinous process or at the L4-L5 intervertebral space. Full term parturient women undergo various physical changes. Therefore, determining the vertebral level with Tuffier's line based on palpation inevitably is not very accurate. The aim of this study was to use ultrasound to verify the difference between vertebral levels...
متن کاملAccuracy of placement of extradural needles in the L3-4 interspace: comparison of two methods of identifying L4.
The certainty with which the L3-4 vertebral interspace can be identified was investigated by studying 50 cadavers. These were allocated randomly to two groups, differing in the way in which the L4 spinous process was identified. Identification of L4 by physically constructing Tuffier's line on the subject led to an increase in the number of catheters sited at the correct level (P less than 0.01).

متن کاملMapping intended spinal site of care from the upright to prone position: an interexaminer reliability study
BACKGROUND Upright examination procedures like radiology, thermography, manual muscle testing, and spinal motion palpation may lead to spinal interventions with the patient prone. The reliability and accuracy of mapping upright examination findings to the prone position is unknown. This study had 2 primary goals: (1) investigate how erroneous spine-scapular landmark associations may lead to err...
متن کاملsystematic review of the characteristics of ultrasound measurements in the evaluation of spinal curvatures in scoliosis patients
Abstract Aims: Scoliosis is one of the secondary complications in amputation veterans, which requires periodic evaluations. The gold standard for evaluating the spine is radiography, which has caused many concerns due to the very high doses of X-ray radiation. For this reason, therapists are finding for an alternative method for this tool, so ultrasound is a non-invasive tool with different me...
