OBJECTIVETo study the outcomes of surgeries for acute central cervical spinal cord injury without cervical spine fracture or dislocation in young and middle-aged patients.

METHODSThe clinical data of 58 young and middle-aged patients with acute central cervical spinal cord injury treated in our hospital between August 2005 and August 2009 were analyzed retrospectively. Of these patients, 33 (24 males and 9 females) received surgical treatment and 25 (17 males and 8 females) had conservative therapy. The ASIA grade and ASIA motor and sensory score were used for evaluation at admission and at 14 days and 1 year after the treatment. The neurological symptoms and treatment outcomes in the two groups were evaluated.

RESULTSThe proportion of patients with ASIA grade D-E and the ASIA motor and sensory scores were all significantly higher in the surgical group than in the non-surgical treatment group (P<0.05).

CONCLUSIONFor young and middle-aged patients with central cervical spinal cord injury, immediate surgery can relieve the pressure on the injured spinal cord and improve the micro-circulation to promote functional recovery of the spinal cord.

OBJECTIVE: To summarize the characteristics of clinic and pathology of the knee menisci injury with sclerosis denaturalization and to discuss the mechanism of the sclerosis and its clinic significance. METHODS: We retrospectively analyzed the diagnosis and treatment and healing of the knee menisci with the sclerosis denatured injury from 1989 to 2003. The changes of the partial meniscus with sclerosis denaturalization were observed in tissue section. RESULTS: Menisci with sclerosis denaturalization occupied 24.1%, and 77.6% of them subordinated to simple sclerosis denaturalization without tear. Their characteristics were that the manifestations were not except typical knee pain, tenderness at joint line,integrity shape with dull or less lubricity and tiny grand on the super face of menisci under the arthroscopy,and trembles could be touched by a probe. Pathology showed the formation of local sclerosis with the histological changes of fibro-hyperplasia, hyaline degeneration and mucous degeneration in the menisci. No operation obtained curative effects. Symptoms can be eliminated by the excision of the menisci with sclerosis denaturalization. CONCLUSION The clinic of simple meniscus injury with sclerosis denaturalization are non-typical and arthroscopic check-up is valuable for the diagnosis. The menisci can be removed from the patients suffered from heavy symptoms for a long time.

OBJECTIVETo observe the therapeutic efficacy of Modified Taohe Chengqi Granule (MTCG) combined mannitol for treating complicated edema in affected limbs of patients after tibiofibulas double fracture operation (TDFO).

METHODSTotally 64 TDFO patients complicated edema were randomly assigned to the treated group and the control group, 32 in each group. Those in the treated group took MTCG combined intravenous dripping of mannitol, while those in the control group received intravenous dripping of mannitol alone. The treatment course was 1 week. The clinical efficacy, the onset time, the swelling degree, and the pain index were observed and compared between the two groups.

RESULTSOne week after operation, the effective rate was 98.0% and the markedly effective rate was 87.5% in the treated group, while they were 78.0% and 56.9% respectively in the control group. Better results were obtained in the treated group, showing statistical difference when compared with the control group (P < 0.05). As for the onset time for swelling subsiding, it was (2.4 +/- 1.3) days in the treated group and (3.8 +/- 2.9) days in the control group. There was statistical difference between the two groups (P < 0.05). Better effects on the swelling subsiding degree and the pain index were obtained in the treated group, showing statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSMTCG combined mannitol could obviously abate the edema in affected limbs of patients after TDFO. It was a better treatment method for managing edema in the peri-operative period of orthopedics.

OBJECTIVE: To explore the operation method in treating patellar instability guided by arthroscopy and to evaluate its therapeutic effects. METHODS: Thirty-two patients (34 knees) with patellar instability including 2 patellar tilt (2 knees), 26 (27 knees) patellar subluxation, and 4 (5 knees) patellar dislocation, diagnosed by clinical and arthroscopical standard, were treated with anterior transfer of the gracilis or medial transfer of the tibial tuberosity based on the lateral retinacular release and medial tightening. RESULTS: Twenty-eight patients were followed up for 5-87 (mean 36.6) months. The excellence rates was 92.8%. CONCLUSION The patellofemoral alignment can be seen directly and dynamically under the arthroscopy. The combinational treatment including anterior transfer of the gracilis in repairing patellar instability can avoid the recurrence effectively and get satisfactory results.

OBJECTIVE: To investigate the effect of interventional therapy in the treatment of intervertebral space infection. METHODS: The needle was punctured into the infected intervertebral space from the post-lateral side of the spine monitored by X-rays. The pus was drained, the degenerative disc tissues and necrosis tissues were excised and taken out, and at the end a drainaging catheter was put into the space through the needle. The patient should lie in bed absolutely. The antibiotics was injected into the space through the silicon catheter every day. Three to four weeks later, the catheter was removed. RESULTS: All the 8 patients got good results after the therapy. The low back pain was dramatically alleviated instantly at the day of operation. Erythrocyte sedimental rate gradually descended. After 3 approximately 4 weeks of treatment,the catheter was removed. CONCLUSION Interventional therapy of the intervertebral space infection has notable advantage over the open operation.

Objective: To develop a Chinese version of Vertigo Symptom Scale ( VSS-C) and to examine its reliability and validity .Methods:The VSS was translated into Chinese and developed a Chinese version VSS ( VSS-C ) with the consent of the author .The VSS-C scale was tested in 52 subjects with cervical spondylosis of vertebral artery type ( CSA group ) and 21healthy subjects ( control group ) .In CSA group VSS-C scale and SF-36 scale investigation was performed for 2 times with 1 week interval , after receiving 1-week orthopedic rehabilitation the patients were evaluated with the VSS -C and SF-36 scale;while subjects in control group received the investigation twice in two weeks.The reliability of the scale was evaluated with Cronbach's alpha method and the correlation between SF-36 scale and the VSS-C were also evaluated for the validity . Results:The internal consistency of VSS-C was good with Cronbach's alpha of 0.886 . Test-retest reliability was also very good with an intraclass correlation coefficient ( ICC) between two time points , being 0.970 for VSS-C,0.965 for VSS-AA and 0.992 for the VSS-VER.Regarding concurrent validity ,significant low correlation was found between the VSS-AA and VSS-VER ( r=0.379 ,P<0.05 ) .Significant expected correlation was detected between the VSS-C and SF-36 ( r>0.5 ,P<0.05 ) .The independent-samples t test results ( t=6.261 ,P<0.01 ) of the CSA group and the control group showed that the VSS-C was able to distinguish healthy people from CSA patients . The paired-samples t test results ( t =5.513 , P <0.01 ) showed that VSS-C reflected the improvement of patients after treatment of Chinese massage manipulation .Conclusion:The Chinese version of VSS has a high comprehensibility , internal consistency and validity, and it can be a useful instrument for evaluation of patients with cervical spondylosis of vertebral artery type in China .

OBJECTIVETo analyze the relationship between position of head, cervical curvature type and associated cervical balance parameters in a neutral looking-forward posture.

METHODSCervical lateral X-rays of 60 patients with cervical spondylosis were selected from January to December 2015. There were 22 males and 38 females with an average age of (35.5±10.9) years old. The measured parameters included cervical curvature type, McGregor slope, C2 lower end plate slope, T1 slope, center of gravity to C7 sagittal vertical offset (CG-C7 SVA), and C2 to C7 sagittal vertical offset (C2-C7 SVA). The parameters were analyzed using Spearman correlation.

RESULTSThe cervical curvature type was significantly correlated with C2 lower endplate slope, C0-C2 angle (total degree of C2 lower endplate slope plus McGregor slope), CG-C7 SVA and T1 slope (<0.05), but it was not significantly correlated McGregor slope (>0.05). C2 lower endplate slope and C2-C7 SVA (r=0.87) were significantly (<0.05) correlated with CG-C7 SVA (<0.05).

CONCLUSIONSThere was certain some relationship among position of head, cervical curvature type and associated cervical balance parameters in a neutral looking-forward posture. The center of gravity of the head would backwards shift following faced upward. A position of extension with posterior-shifting of the head would suggest that it may be accompanied with a relatively normal lordosis of the cervical spine. Some patients with abnormal curvature showed slightly bended head in the natural posture. Health education toward these people would be meaningful to restore the balance of their neck.
