To introduce the location and course of S1, S2 sacral nerve root tunnel and to clarify the significance of the anterior aspect of sacral nerve root tunnel on placement of iliosacral screw on the standard lateral sacral view. ⋯ It can prevent the iliosacral screw from penetrating the sacral nerve root tunnel and vertebral canal when recognizing the anterior aspect of sacral nerve root tunnel and choosing it as the caudal-posterior boundary of the "safe zone" on the standard lateral sacral view.
-
To compare the clinical effects of close manipulative reduction combined with minimally invasive percutaneous plate fixation(MIPPO) and conventional open reduction and internal fixation (ORIF) for the treatment of proximal humerus fractures. ⋯ The close manipulative reduction combined with MIPPO is a better choice for fixation of proximal humerus fractures, compared with conventional plate. This method possesses such advantages as a shorter incision, less disturbance of the blood supply and stable fixation of the fracture, allowing early exercise so that the function of shoulder recovers rapidly.
-
To analyzed the relationship between lumbar endplate Modic area changes rate and low back pain by measuring MRI T2 sagittal image of lumbar endplate Modic area changes rate. ⋯ Modic I and II area changes rate of of patients with low back pain is closely related to the degree of pain low back pain, Modic III area changes rate is not significant correlated to the degree of lower back pain.
-
To investigate the effects of locking plate fixation through lateral deltoid approach for proximal humeral fracture combined with micro-invasive percutaneous plating (MIPPO) technique. ⋯ Lateral deltoid approach combined with locking plate fixation for treatment of proximal humeral fracture has advantages of small invasion,less blood lossing, short operative time, stable fixation, high rate of fracture healing, and satisfactory functional recovery.
