[Bilateral transpedicular balloon kyphoplasty for the treatment of osteoporotic vertebral compressive fractures].

Objective: To compare clinical outcomes of bilateral transpedicular balloon kyphoplasty for the treatment of ordinary osteoporotic vertebral compressive fracture (OVCF) and severe osteoporotic vertebral compressive fracture.

Methods: From Junary 2009 to Febuary 2011, 60 patients (70 vertebrae) with osteoporotic vertebral compressive fracture were included. All patients were treated by bilateral transpedicular balloon kyphoplasty combined with postural reduction, including 10 males and 50 females aged from 59 to 90 years old with an average of 72.

[The clinical value of end plate rings in preventing subsidence of titanium cage in anterior cervical corpectomy and fusion surgery].

Objective: To evaluate the clinical results of using end plate rings in preventing subsidence of titanium cage in anterior cervical corpectomy and fusion (ACCF) surgery.

Methods: The clinical data of 71 patients with cervical spondylotic myelopathy underwent ACCF in single segment from February 2008 to February 2011 were retrospectively analyzed. There were 38 males and 33 females, aged from 39 to 74 years old with a mean of 53.

[Modified Stoppa approach in treatment of pelvic and acetabular fractures].

Objective: To evaluate the modified Stoppa approach in treatment of pelvic and acetabular fractures.

Methods: From March 2010 to May 2012,16 patients with pelvic fractures and 7 patients with acetabutar fractures were treated by open reduction and internal fixation through the modified Stoppa approach,involving 18 males and 5 females with an average age of 39 years ranging from 17 to 65. By Tile classification, 16 cases of pelvic fractures included 1 case of B1, 2 of B2, 3 of B3, 4 of C1-1, 2 of C1-2, 2 of C1-3, and 1 of C2.

(1E,4E)-1-(Thio-phen-2-yl)-5-(2,6,6-trimethyl-cyclo-hex-1-en-1-yl)penta-1,4-dien-3-one.

In the title curcumin-ionone derivative, C(18)H(22)OS, the dihedral angle between the thia-zole ring and the mean plane through the cyclo-hexene ring is 5.16 (10)°. The mol-ecule has an E conformation for each of the olefinic bonds.

(1E,4E)-1-(2-Nitro-phen-yl)-5-(2,6,6-trimethyl-cyclo-hex-1-en-1-yl)penta-1,4-dien-3-one.

In the title curcumin-ionone derivative, C(20)H(23)NO(3), the dihedral angle between the cyclo-hexene and benzene rings is 21.03 (8)°, with both double bonds in the inter-linking olefinic chain adopting E conformations. Two of the methyl-ene groups of the β-ionone ring are disordered over two sets of sites with occupancy ratios of 0.

[Clinical application study of modified Moore classification in lower cervical spine injuries].

Objective: To analyze the clinical application of modified Moore classification in lower cervical spine injuries.

Methods: Modified Moore classification was applied in the morphologic description of 200 patients (including 165 males, 35 females,age ranging from 19 to 88 years,with an average age of 52 years) with lower cervical spine injuries from August 2006 to March 2010, cervical spine injury severity score (quantification of stability) in combination with yes/no neurological injury status to classify their clinical diagnosis and management. The treatment was selected according to the fracture type, stability, compression injury of spinal cord or nerve roots, stability of ligamentous injury and other reference factors.
