Cervical spondylomyelopathy (CSM) is rarely identified in small-breed dogs. Two neutered female Pekingese dogs (less than 5 kg of body weight) with primary complaints of neck pain and paretic gait were presented. These cases were diagnosed as CSM secondary to vertebral instability through cervical survey radiography, myelography, computed tomography (CT) and CT-myelography. The combinatory treatments of ventral slot decompression, cancellous bone graft and external coaptation were performed. Clinical condition of both dogs remarkably improved and no complications or recurrence occurred following the surgical procedures. In small-breed dogs with CSM, the combination of decompression through ventral slot and stabilization through bone fusion is an effective treatment.

The purpose of this study was to evaluate and compare by finite element analysis the biomechanical performance, in terms of cervical stand-alone cage screw insert angle (Type 3 - 5: 2 Screws) and screw arrangement (Type 6 and 7: 3 Screws / Type 8 and 9: 4 Screws), and the range of motion (ROM) of traditional anterior cervical discectomy of a fusion device (Type 1: Cage / Type 2: Cage + ACP). Our study suggests that the biomechanical behavior of a postoperative cervical spine could indeed be influenced by design features, such as screw angle and number of screws. In particular, ROM and the risk of subsidence were more sensitive during extension about type 5 (Insert Angle $20^{\circ}$). Our study also suggested that the number of screw asymmetries between up and down for type 6 and 7 could result in differences in the risk of screw fracture manifesting in different clinical aspects.

To investigate the developmental stages of dental and skeletal maturation by ages and the correlations among dental maturity, skeletal maturity of cervical vertebrae, and that of hand-and-wrist, the author used the cephalograms, orthopantomograms, and hand-and-wrist radiograms of 1055 patients (male 458, female 597) aged 7 to 20 years old. In the cephalograms, the skeletal maturity stages of each bone were mainly assessed by Hassel and Farman's cervical vertebrae maturation indicators (CVMI) method. In the orthopantomograms, the dental maturity stages of each tooth were mainly assessed by Nolla's tooth calcification stages method. In the hand-and-wrist radiograms, the skeletal maturity stages of each bone were mainly assessed by Fishman's skeletal maturity indicators (SMI) method. The results were as follows. 1. There was a high correlation among dental maturity, skeletal maturity of cervical vertebrae, and that of hand-and-wrist in the both sexes (P<0.001). 2. There was a high correlation (r=0.91-0.93) between skeletal maturity of cervical vertebrae and that of hand-and-wrist. 3. There was a high correlation (r>0.8) between skeletal maturity of hand-and-wrist and maturity of upper and lower canine, first premolar, and second premolar. 4. There was high a correlation(r=0.8) between skeletal maturity of cervical vertebrae and maturity of upper canine. 5. By the ages, dental maturity, skeletal maturity of cervical vertebrae, and that of hand-and-wrist were obtained in the both sexes. In summary, dental maturity, skeletal maturity of cervical vertebrae, and that of hand-and-wrist we of sufficient diagnostic worth as an index to predict adolescent growth.

Purpose : The purpose of this study is to evaluate the usefulness of 6 Dimensional Skull Tracking(6DST) in Cyberknife Stereotactic Body Radiation Therapy(SBRT) for the first and second cervical vertebrae(C1 and C2) metastasis. Methode and material : The Computed Tomography (Lightspeed VCT 64, General Electric Co. Waukesha, WI, USA) was used to acquire the CT images of the 9 patients with cervical vertebrae(C1 and C2) metastasis. Treatment plans for Xsight spine tracking and 6 Dimensional skull tracking were established with planning system (Multiplan system Version 4.6, Accuray, US). The results of XST and 6DST for each patient were analyzed with Microsoft Excel 2010. Result : The Maximum offsets of XST for C1 were 0.9 mm in Y(supero-inferior), 0.9 mm in Z(antero-posterior), 0.7 mm in X(left-right) direction, and rotations were and 1.0 degrees roll, 1.0 degrees pitch and 1.2 degrees yaw. The Maximum offsets of 6DST for C1 were 0.7 mm, 0.7 mm, 0.9 mm and $1.0^{\circ}$, $1.0^{\circ}$, $1.2^{\circ}$ for Y, Z, X and Roll, Pitch, Yaw. The Maximum offsets of XST and 6DST for C2 were 0.7 mm, 0.7 mm, 0.8 mm and $0.9^{\circ}$, $1.0^{\circ}$, $1.8^{\circ}$, and 0.9 mm, 0.7 mm, 0.9 mm and $0.9^{\circ}$, $0.9^{\circ}$, $1.0^{\circ}$ for Y, Z, X and Roll, Pitch, Yaw, respectively. Conclusion : XST and 6DST showed identical results for translations and rotations within the tolerance. It is possible to simplify the treatment time and procedure by using the 6DST. Therefore, 6DST is very useful methode with XST among the various tracking methods in Cyberknife for the patients with C1, C2 vertebral metastasis.

Fractures of isolated spinous processes of cervical and thoracic vertebrae are called as Clay shoveler's fracture. Such fractures related to sports activities are quite rare. In this report, a case of 27-year-old male with isolated spinous process fracture of C7 during golf swing is reported. The patient was prescribed on muscle relaxant and analgesic therapy. Cervical immobilization was maintained for four weeks with a cervical collar. The patient gradually recovered and was asymptomatic. He started playing golf twice a week after 5 months from the onset of pain.

Osteochondroma is the most common benign tumor in bone, consist of 40%, but, rare in spine area occupying only 2%. We report a case of osteochondroma that was in the 5th and 6th spinous process of cervical spine. We performed en bloc excisional biopsy of the bony mass. And the patient is doing well without evidence of local recurrence at 1 year after surgery. Further follow-up is necessary to observe local recurrence.

Background: The purpose of this study was to identify the effects of morphological Change of cervical spine to apply to neck retraction and extension regarding the straight deformity of cervical spine. Methods: A 40-year male subject with straight deformity of cervical spine participated in this study. The study subject underwent a cervical lateral radiography on the static position, neck retraction and neck extension on standing. Measurement method were using computer-based digital radiogram on a picture achieving computer system forthe centroid method, Cobb's angle and Jackson's angle. Results: Neck retraction was increased kyphosis on the C2-4 with lordosis on the C5-7. Neck extension was increased lordosis on the C2-7. Conclusions: These findings suggest that neck retraction was increased kyphosis and neck extension was increased lordosis based on the straight deformity of cervical spine. Therefore, we should be consider that neck extension exercise when increased lordosis for the patients of straight deformity of cervical spine.

This is to investigate the physical properties of the commercially available Soft, Thomas, Minerva, and Philadelphia cervical braces which are widely used in orthopedics, neurosurgery, and rehabilitation medicine clinics as assisting devices for physical stabilization of cervical vertebrates, to use as a basic data for designing new type brace. Tensile strengths were observed by universal mechanical measuring device and Thomas brace required the highest stress to break by tensile stress. Durabilities against continuous frictional forces were also determined, and Minerva brace demonstrated the longest frictional time until being perforated. According to these results, poly ethlene is recommendable as a frame and preparation of pores in the material is favorable to provide ventilation to skin.

Acupuncture, which is a procedure of inserting needles in a specific portion of the body to control pain, is conducted widely. The procedure is considered relatively safe because of its minimal side effects and low occurrence (1 in 200,000). On the other hand, its side effects include neurological damage, infection, hematoma, emphysema, etc. The authors report a case of cervical neurological damage that occurred after an acupuncture procedure.

Outcomes of non-surgical and surgical treatments for thoracolumbar intervertebral disc disease (IVDD) are well-reported. However, little is known regarding the outcome for treatments of cervical IVDD. This study systematically reviewed the outcomes in dogs with cervical IVDD that were managed non-surgically and surgically. Clinical success rates for surgical treatment were significantly higher (100%) than for non-surgical treatment (51.4%). In the non-surgical treatment group, clinical success rates were negatively correlated with spinal cord compression rates. Based on the results of this study, surgical treatment is deemed more effective than non-surgical treatment for dogs with cervical IVDD. Also, the degree of spinal cord compression on computed tomography or magnetic resonance imaging is a useful prognostic indicator before non-surgical treatment.
