OBJECTIVETo discuss on the effect of cervical spondylotic myelopathy before and after surgery and assess its indications and efficacy.

METHODSFrom June 2002 to June 2006, 125 patients with cervical spondylotic myelopathy were analyzed retrospectively involving 58 anterior routine and 67 posterior routine, of which 71 cases of males, 54 cases of females, aged from 28 to 69 years (average 53.4 years). The course was 0.5 to 48 months (means 14 months). According to JOA score system preoperative and postoperative nerve function were analyzed, summarized anterior and posterior cervical spine surgery.

RESULTSAll patients were followed up for from 6 to 30 months (average of 18 months). According to JOA score criteria: anterior cervical surgery preoperative JOA score was (8.78 +/- 2.43) points, postoperative JOA score was (14.68 +/- 2.37) points, the results were excellent in 40 cases, good in 10 cases, effective in 6. Posterior surgical group preoperative JOA score was (8.49 +/- 2.58) points, postoperative JOA score was (14.26 +/- 2.83) points, the results were excellent in 42 cases, good in 12 cases, effective in 8. Invalid operation occurrenced in 6 cases included 2 of anterior, 4 of posterior. The postoperative symptoms had worsed in 1 case of posterior operation. The two groups had no statistical difference in efficacy, but there were differences statistically in the same approach comparing preoperative and postoperative.

CONCLUSIONBoth anterior and posterior approaches have fine effect to the treatment of cervical spondylotic myelopathy (CSM). But the selection of the indication is very important, the patients with the pressure from anterior, the short-level changes, and the main symptoms of pyramid trac compression, adopt anterior approach on principle. While the patients with the pressure of spinal cord from posterior, multilevel changes, main symptoms of sensory disturbances, and accompanied by cervical spine canal stenosis mainly is introduced posterior approach.

OBJECTIVE: The purpose of the study is to investigate the relationship between dental calcification stages (DCS) and cervical vertebral maturation stages (CVMS) in patients with unilateral complete cleft lips and palates (UCLP) and to provide a theoretical basis for the treatment time selection of cleft lip and palate (CLP) patients. METHODS: A total of 123 UCLP patients and 215 non-CLP subjects were selected. The DCS of the left mandibular canine, premolar, and second molar in non-CLP subjects and on both cleft sides of UCLP patients were assessed utilizing the Demirjian method. CVMS was observed utilizing the Baccetti method. The results were analyzed by Spearman rank correlation, and the correlation coefficients were compared. RESULTS: There was a correlation between the CVMS and the DCS of the left mandibular canine, the first premolar, the second premolar, and the second molar in the non-CLP subjects and on both cleft sides of the UCLP patients (r=0.762-0.864, P<0.05; r=0.809-0.914, P<0.05, respectively). The correlation between the CVMS and the DCS of the mandibular first premolar was highest among the UCLP patients. Except for the first and the second premolars of UCLP females, the correlation between the DCS and the CVMS of the other teeth did not differ among the non-CLP subjects (P>0.05). CONCLUSIONS DCS can be utilized as a biological index to determine the growth development statuses. The correlation between the CVMS and the DCS of the mandibular first premolar was the highest.

Despite a large number of rear-end collisions on the road and a high frequency of whiplash injuries reported, the mechanism of whiplash injuries is not completely understood. One of the reasons is that the injury is not necessarily accompanied by obvious tissue damage detectable by X-ray or MRI. An extensive series of biomechanics studies, including injury epidemiology, neck kinematics, facet capsule ligament mechanics, injury mechanisms and injury criteria, were undertaken to help elucidate these whiplash injury mechanisms and gain a better understanding of cervical facet pain. These studies provide the following evidences to help explain the mechanisms of the whiplash injury: (1) Whiplash injuries are generally considered to be a soft tissue injury of the neck with symptoms such as neck pain and stiffness, shoulder weakness, dizziness, headache and memory loss, etc. (2) Based on kinematical studies on the cadaver and volunteers, there are three distinct periods that have the potential to cause injury to the neck. In the first stage, flexural deformation of the neck is observed along with a loss of cervical lordosis; in the second stage, the cervical spine assumes an S-shaped curve as the lower vertebrae begin to extend and gradually cause the upper vertebrae to extend; during the final stage, the entire neck is extended due to the extension moments at both ends. (3) The in vivo environment afforded by rodent models of injury offers particular utility for linking mechanics, nociception and behavioral outcomes. Experimental findings have examined strains across the facet joint as a mechanism of whiplash injury, and suggested a capsular strain threshold or a vertebral distraction threshold for whiplash-related injury, potentially producing neck pain. (4) Injuries to the facet capsule region of the neck are a major source of post-crash pain. There are several hypotheses on how whiplash-associated injury may occur and three of these injuries are related to strains within the facet capsule connected with events early in the impact. (5) There are several possible injury criteria to correlate with the duration of symptoms during reconstructions of actual crashes. These results form the biomechanical basis for a hypothesis that the facet joint capsule is a source of neck pain and that the pain may arise from large strains in the joint capsule that will cause pain receptors to fire.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

OBJECTIVETo explore clinical presentations and the operational opportunity of traumatic cervical disc herniation.

METHODSFrom June 2002 to June 2009,40 patients with traumatic cervical disc herniation were treated. There were 24 males and 16 females, with an average age of 43.2 years old ranging from 30 to 56 years. There were 36 patients with single intervertebral disc herniation and 4 patients with double. The injury level of those patients were at C3,4 in 16 cases, C4,5 in 10 cases, C5,6 in 12 cases and C6,7 in 6 cases. Among them, 18 patients showed spinal cord signal changes by MRI, 5 patients suffered from nothing but neck and shoulder pain, 8 patients with nerve root stimulation; 10 patients with spinal cord compression, and 17 patients had both nerve root stimulation and spinal cord compression symptoms. Conservative treatment were applied to 13 patients with neck and shoulder pain and nerve root stimulation, 5 cases of which were transferred to operation in case of poor effects, and Odom criteria were used to assess operational effects. Twenty-seven patients with spinal cord compression accepted operation from 1 to 27days after their trauma, 16 of which were operated in 5 days (early operational group with an JOA score of 11.3 +/- 2.8), other 11 cases were operated from 5 to 27 days (delayed operational group with an JOA score of 11.4 +/- 2.9 ), then functional assessment of spinal cord were assessed according to JOA criteria.

RESULTSThree patients who were transferred from conservative treatment recovered excellently according to Odom criteria and the other 2 were good at final followed-up. JOA score of early operational group increased from (11.3 +/- 2.8) to (15.3 +/- 1.8) one week after operation (P < 0.01), and (15.9 +/- 1.4) at final followed-up (P < 0.01). JOA score of delayed operational group increased from (11.4 +/- 2.9) to (14.0 +/- 2.6) one week after operation (P < 0.01), and (15.3 +/- 1.5) at final followed-up (P < 0.01). The recovery ratio of JOA score of early operational group were (74.6 +/- 16.8)% 1 week after operation,and increased to (85.6 +/- 13.6)% at final followed-up; while that of delayed operational group were (50.9 +/- 17.5)% and (68.2 +/- 21.5)%, and there were significant difference between early operational group and delayed operational group both at 1 week postoperation and final followup (P < 0.05).

CONCLUSIONThere are some difference in pathological segment and imaging manifestation between traumatic cervical disc herniation and cervical spondylosis. Early operation is favorable to the recovery of neurological function in patients with spinal cord compression.

OBJECTIVETo investigate the biomechanical effect of anterior screw fixation on the type II fractured odontoid process.

METHODSTwenty fresh human C1-C2 vertebrae specimens were harvested and randomly divided into three groups. The angle of type II fracture line was 0 degree in group I (n=6), 17 degrees in group II (n=8) and 25 degrees in group III (n=6). The fractures were treated by anterior screw fixation. Insertion torque,maximal axial pullout force and stiffness of the bone-screw were tested.

RESULTSThere was no significant difference of screw insertion torque and the pull-out strength between each group. The displacement of the odontoid fragment had an association to the angle of the fracture line,the displacement of the small angle was significantly higher than that of the large one (P < 0.5). No significant difference of structure stiffness of the bone-screw was found between each group.

CONCLUSIONAnterior screw fixation is feasible for type II odontoid fracture with certain fracture line extends from anteroinferior to posterosuperior.

Whiplash injury is a common injures in our daily lives, but the mechanism of it and the best treatment is largely unknown. The development of chronic pain and disability following whiplash injury is not uncommon and results in substantial social and economic costs. Clinical manifestation and recovery time are difference, which make it difficult for doctor diagnosis and treatment. The current study have shown that the social class, severity of collision, compensation and lawsuit, physical and psychological factors were relevant predictors for the outcome of whiplash. This article is try to overview the status quo of the whiplash injury.

Subjective symptoms of a cool or warm sensation in the arm could be shown objectively by using of thermography with the detection of thermal change in the case of radiculopathy, including cervical disc herniation (CDH). However, the precise location of each thermal change at CDH has not been established in humans. This study used digital infrared thermographic imaging (DITI) for 50 controls and 115 CDH patients, analyzed the data statistically with t-test, and defined the areas of thermatomal change in CDH C3/4, C4/5, C5/6, C6/7 and C7/T1. The temperature of the upper trunk and upper extremities of the control group ranged from 29.8 degrees C to 32.8 degrees C. The minimal abnormal thermal difference in the right and left upper extremities ranged from 0.1 degree C to 0.3 degree C in 99% confidence interval. If delta T was more than 0.1 degree C, the anterior middle shoulder sector was considered abnormal (p < 0.01). If delta T was more than 0.3 degree C, the medial upper aspect of the forearm and dorsal aspect of the arm, some areas of the palm and anterior part of the fourth finger, and their opposite side sectors and all dorsal aspects of fingers were considered abnormal (p < 0.01). Other areas except those mentioned above were considered abnormal if delta T was more than 0.2 degree C (p < 0.01). In p < 0.05, thermal change in CDH C3/4 included the posterior upper back and shoulder and the anterior shoulder. Thermal change in CDH C4/5 included the middle and lateral aspect of the triceps muscle, proximal radial region, the posterior medial aspect of the forearm and distal lateral forearm. Thermal change in CDH C5/6 included the anterior aspects of the thenar, thumb and second finger and the anterior aspects of the radial region and posterior aspects of the pararadial region. Thermal change in CDH C6/7 included the posterior aspect of the ulnar and palmar region and the anterior aspects of the ulnar region and some fingers. Thermal change in CDH C7/T1 included the scapula and posterior medial aspect of the arm and the anterior medial aspect of the arm. The areas of thermal change in each CDH included wider sensory dermatome and sympathetic dermatome. There was a statistically significant change of temperature in the areas of thermal change in all CDH patients. In conclusion, the areas of thermal change in CDH can be helpful in diagnosing the level of disc protrusion and in detecting the symptomatic level in multiple CDH patients.

OBJECTIVETo compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type.

METHODSSixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared.

RESULTSIn the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01).

CONCLUSIONThe needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.
