Clinical observation on the treatment of cervical degenerative diseases with Hybrid surgery / 中国骨伤

OBJECTIVE@#To investigate the clinical effect of anterior cervical Hybrid surgery in the treatment of cervical degenerative diseases (CDD) and observe the incidence of heterotopic ossification of disc replacement segment at 1 year after surgery.@*METHODS@#From January 2015 to April 2018, 35 patients who received anterior cervical hybrid surgery met the inclusion and exclusion criteria and the complete clinical follow up data were analyzed retrospectively. Complete imaging follow-up data were obtained from 24 patients. There were 15 males and 20 females, aged from 39 to 70(55.57±7.73) years old. The amount of bleeding was for 20 to 100 (40.29±18.39) ml, and the hospitalstay was for 4 to 28(11.03±4.63) days, and the follow-up time was(12.97±1.36) months. Clinical outcomes were assessed by the Tanaka Yasushi cervical spondylitis symptom scale 20 score (YT20), and Japanese Orthopaedic Association (JOA) score. The occurrence of heterotopic ossification after Hybrid surgery was evaluated by X-ray according to McAfee standard one year after operation. Patients with or without heterotopic ossificationwere divided into two groups and their clinical effects were compared.@*RESULTS@#At the final follow up, the mean YT20 score and JOA score were significantly higher than those before operation (P <0.05), and the average improvement rate of JOA was (70.66 ±0.44)%. One year after operation, the heterotopic ossification occurred in 10 of 24 segments, with incidence of 41.70%(10/24), including 29.20% in gradeⅠand 12.50% in gradeⅡ. The results of clinical efficacy comparison between patients with and without heterotopic ossification were as follows:there was no significant difference in JOA score before and after operation (@*CONCLUSION@#The short-term clinical effect of Hybrid surgery is satisfactory for cervical degenerative diseases, and the cause of heterotopic ossification still needs tobe further explored.

Progress on establishment of animal model of osteoarthritis by intra-articular injection / 中国骨伤

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.

Study about Traditional Chinese Medicine syndrome of adolescent neck pain / 中国骨伤

<p><b>OBJECTIVE</b>To preliminarily research the formular about the Traditional Chinese Medicine (TCM) syndrome of adolescent neck pain.</p><p><b>METHODS</b>An observation table of adolescent neck pain syndromes was formulated,and 1 397 patients with adolescent neck pain were investigated to establish a database of adolescent neck pain. The Descriptive Statistical Analysis and Hierarchical Cluster Analysis were performed by statistical software.</p><p><b>RESULTS</b>Totally 60 TCM symptoms was clustered into 4 TCM syndromes by Hierarchical Cluster Analysis. The expert panel of TCM syndromes preliminarily formulate 4 TCM syndromes of adolescent neck pain by analyzing the result of Cluster Analysis and discussing their clinical experience.</p><p><b>CONCLUSION</b>Adolescent neck pain is a category of Tendon Trauma's Bi-syndrome of TCM. Ying, Wei, Qi and blood block caused by exopathy, strains, and internal injury is considered as the main pathogenesis of adolescent neck pain. Base on statistical result and expert's opinions, 4 TCM syndromes about adolescent neck pain were formulated: cold-dampness syndrome, dampness-heat blockage syndrome, liver-stagnation and spleen-deficiency syndrome, Qi and Yin deficiency of both heart and kidney syndrome.</p>

Soft tissue changes observed through musculoskeletal ultrasound in the treatment of knee osteoarthritis with needle-knife / 中国骨伤

<p><b>OBJECTIVE</b>To study soft tissue changes observed through musculoskeletal ultrasound (MSUS) in the treatment of knee osteoarthritis with needle-knife, so as to provide MSUS basis for needle-knife in the treatment of knee osteoarthritis.</p><p><b>METHODS</b>Forty patients with knee osteoarthritis treated in the Third Affiliated Hospital of Beijing University of Chinese Medicine from December 2011 to December 2012 were selected according to inclusion and exclusion criteria. All the patients were treated with needle-knife release method. The VAS scores and knee joint circumference were recorded before treatment and 2 weeks after treatment. The changes of knee joint hydrops articuli and joint synovial thickness were measured through MSUS.</p><p><b>RESULTS</b>The knee pain index was 6.850 +/- 1.417 before treatment and 2.790 +/- 1.299 after treatment;the index after treatment was lower than that of before treatment. The knee joint circumference was 407.320 +/- 45.151 mm before treatment and 391.240 +/- 41.129 mm after treatment; the knee joint circumference decreased after treatment. The amount of hydrops articuli observed by musculoskeletal ultrasound showed that 47 knees were cured, 19 knees improved and 2 knees failed. The synovial membrane thickness: 43 knees cured, 17 knees improved and 8 knees failed.</p><p><b>CONCLUSION</b>The hydrops articuli and synovial thickness of knee joint of patients with knee osteoarthritis observed under the MSUS is consistent with the main symptoms and signs, which suggests that MSUS observation on soft tissue changes before and after needle knife in the treatment of knee osteoarthritis with high reliability.</p>
