Experimental Studies of the rhBMP-2 Enhancing Bone Consolidation of Distraction Osteogenesis in Rabbits and the Condition of BMSc Proliferation and Differentiation
[Result]The elbow joint was finally extended to 0°～10°with an average 45°correction of flexion after an average 32 days of distraction. The range of elbow joint movement increased from pre-operative 75°to post-operative 115°.
The PT was shown to correlate with the children's motor activity (0.52), approaching a new subject (0.39), distraction (-0.34), and the age of entering a nursery (-0.35).
We present three case reports demonstrating the use of distraction lengthening for symptomatic congenital short metatarsals.
In all three cases the distraction lengthening of the fourth metatarsal was performed with an external fixateur system aided by an intramedullary K-wire without any supplemental bone graft.
The arthrolysis can be performed using arthroscopy, the open technique or distraction arthroplasty.
Potential and Limitations of Cephalometric Analysis of Maxillofacial Bone Movement in the Case of LeFort III-Distraction
According to the differential principles of Traditional Chinese Medicine, symptoms during subtotal gastrectomy under acupuncture anesthesia were divided into three groups, namely. 1 ) stasis of "Qi" "and "Xue" * ( pain ) , 2 ) deficiency of "Qi" of "Stomach" *( nausea, vomiting ) and 3 ) disturbance of "Qi" and "Xue" ( palpitation, sweating, distraction ) . Following theory of "Channels* and "Collaterals" , acupoints "Renzhong" , "Chengjiang" ( for pain ) ; "Pishu" , "Zusanli" ( for nausea, vomiting )...

Following theory of "Channels* and "Collaterals" , acupoints "Renzhong" , "Chengjiang" ( for pain ) ; "Pishu" , "Zusanli" ( for nausea, vomiting ) ; "Xinshu" and "Neiguan" (for distraction etc. ) were selected to eliminate these symptoms. In a total of 151 cases, 128 ( 84.8% ) had excellent effect, 20(13.2%) with good effect and 3 (2%) with poor effect. A method of effect determination for acupuncture anesthesia in subtotal gastrectomy was also introduced.
After placing a recording electrode over the exposed epidura of each of 4 rabbits,the sciatic nerve was stimulated.There was evoked spinal cord potential(ESCP)curvesseen on the oscilloscope of a JD-2 electromyograph in every instance.The technic wasused during operation in a total of 16 patients.ESCP were absent in 2 patients withcomplete paraplegia,but were present on the side with some remaining sensation in 3incomplete paraplegia patients.ESCP were recorded before and during Harrington roddistraction in 10...
After placing a recording electrode over the exposed epidura of each of 4 rabbits,the sciatic nerve was stimulated.There was evoked spinal cord potential(ESCP)curvesseen on the oscilloscope of a JD-2 electromyograph in every instance.The technic wasused during operation in a total of 16 patients.ESCP were absent in 2 patients withcomplete paraplegia,but were present on the side with some remaining sensation in 3incomplete paraplegia patients.ESCP were recorded before and during Harrington roddistraction in 10 scoliosis patients.4 of them showed changes in the curves duringdistraction,and the potential returned to normal when over-distraction was stopped.The main display of the change was prolongation of latent period and reduction in curveamplitude.One patient with rheumatoid arthritis of spine had normal ESCP.The authorsfound that ESCP determined by JD-2 electromyograph correlated with the clinical mani-festations,especially with the sensory function.
本文报道刺激坐骨神经时用 JD—2型肌电图机可测得脊髓诱发电位。家兔实验表明诱发电位的波形为 M 波或 H 波,潜伏期为4～6毫秒。16例脊柱疾患中,2例完全性截瘫未能测出诱发电位,3例不完全性截瘫在感觉存在的一侧有诱发电位出现。用 Harrington 棒矫正的10例脊柱侧凸,6例在牵撑时诱发电位无变化,4例有明显变化;1例脊柱类风湿性关节炎伴驼背畸形者无变化。由此提示诱发电位的测定可作为脊柱手术时的监护。
Fifteen cases of unstable thoracic and lumbar spinal fractures with paraplegia were treated with Harrington distraction rods combined with cross wiring. The results were quite satisfactory. There was no loosening of the Harrington rod after operation. Firm fixation of the spine made nursing care easier and complications of paraplegia reduced after operation. Restoration of normal anatomic alignment of the spine might be beneficial for possible recovery of spinal cord injury and the technique is easy to...

There was no loosening of the Harrington rod after operation. Firm fixation of the spine made nursing care easier and complications of paraplegia reduced after operation. Restoration of normal anatomic alignment of the spine might be beneficial for possible recovery of spinal cord injury and the technique is easy to master.
