Objective: Different types of interbody fusion cages are available for use in the surgical treatment of degenerative cervical diseases. The purpose of this study is to assess the technical feasibility, clinical efficacy and radiological results of intervertebral fusion with a carbon composite Osta-Pek frame cage (Co-Ligne AG, Switzerland) following anterior cervical discectomy. Methods: 41 patients (25males and 16females) with minimum 6months follow-up were included in the study. Disc height, cervical lordotic angle, segmental angle, and fusion rate were assessed by lateral radiographs. In this retrospective analysis, clinical outcome was assessed as evaluated according to Odom's criteria. Results: Fifty-four cages were implanted in 30 single-level, 9 two-level, and 2 three-level procedures. The mean disc height, cervical lordosis angle, segmental angle were $4.2{\pm}1.8mm,\;23.5{\pm}7.2^{\circ},\;2.3{\pm}3.3^{\circ}$ pre-operatively and $5.3{\pm}2.1mm,\;24.2{\pm}8.3^{\circ},\;3.8{\pm}3.5^{\circ}$ at 6months after the surgery. Six months after surgery, there was radiographic evidence of fusion in 92.7% (38/41) of the patients. According to Odom's criteria, 37 of 41 (90.2%) patients experienced good to excellent functional recovery. Conclusion: These clinical and radiological results suggest that the carbon composite Osta-Pek frame cages are safe and effective alternative to autologous bone graft after anterior cervical discectomy for treatment of degenerative cervical disease.

Purpose: The primary purpose of this study was to investigate the effects of cervical stabilization exercise (CSE) on hamstring flexibility in patients with neck pain. A secondary purpose of this study was to investigate the effects of cervical range of motion (CROM) and craniovertebral angle (CVA). Methods: This study was a single-blind, randomized, comparative trial. Twenty patients were allocated into either the cranio-cervical flexion exercise (CCFE) group or the CSE group. Before and after the intervention, we measured straight leg raise (SLR), popliteal angle (PA), CROM, and CVA in the sitting and standing positions. Fisher's exact test, the Mann-Whitney test, and Wilcoxon's signed-rank test were used to analyze our data. Results: Both groups showed significant improvements in the value of SLR, PA, cervical extension, cervical rotation, and CVA in the standing position (both, p<.05) after intervention. However, only the CSE group showed significant improvements in cervical right lateral flexion (z=-2.209; p<.01) and cervical left lateral flexion (z=-2.537; p<.05) after intervention. The CSF group showed more significant improvements in SLR, PA, both cervical lateral flexions, and both cervical rotations than the CCFE group. Conclusions: The results of this study will guide future research in identifying the effectiveness of CSE. In conclusion, it can be inferred that CSE has a positive effect on SLR, PA, CROM, and CVA in the standing position in patients with chronic neck pain.

PURPOSE: This study examined the relationship between the cervical lordosis angle (CLA) and the craniovertebral angle (CVA) and between CVA and a cross-sectional area (CSA) of the cervical muscles. METHODS: In 17 healthy college students, the CLA was measured using a posterior tangent technique. The CVA was analyzed using photographic images, and the CSA of the cervical muscles, including longus colli, longus capitis, and sternocleidomastoid, was evaluated using computerized tomography. The Pearson's correlation coefficient was used to determine the relationship between these variables and a neck disability index. RESULTS: The CVA correlated with the CLA and with a CSA of longus colli (r = .487, p = .047 and r = .592, p = .012, respectively). The CLA correlated with a CSA of longus colli (r = .578, p = .015). CONCLUSION: This study clarified the relationship between the postural, structural, and muscular changes in the cervical regions. A significant correlation was observed between the CVA and a CSA of the longus colli with the CLA and between the CVA and the CSA of the longus colli. Prescription strengthening exercises for the deep neck flexors for individuals with a forward head posture and reduced cervical lordosis are useful.

Objective: The purpose of this study was to investigate the effects of sling exercise on the cervical lordotic angle, craniovertebral angle, and head rotation angle among adolescents in the forward head posture. Methods: The subjects include 22 adolescents that recorded a mild level or higher on the posture evaluation index by New York State. They were randomly divided to the hand exercise group (n=11) and the control group (n=11). The former group participated in the sling exercise program three times a week over four weeks in total with each session lasting 60 minutes, whereas the latter group was not included in the program. The cervical lordotic angle, craniovertebral angle, and head rotation angle were measured before and after the intervention. Results: The study compared the cervical lordotic angle between the two groups before and after sling exercise and found that the sling exercise group made an increase of $7.36^{\circ}$ from $21.91^{\circ}$ to $29.27^{\circ}$ after the intervention(p<.05). As for the comparison results of the craniovertebral angle, the sling exercise group made an increase of $5.64^{\circ}$ from $48.91^{\circ}$ to $54.55^{\circ}$ after the intervention (p<.05). As for the comparison results of the cranial-rotation angle, the sling exercise group made an decrease of $-7.73^{\circ}$ from $148.82^{\circ}$ to $141.09^{\circ}$ after the intervention (p<.05). The control group showed no differences before and after the intervention (p>.05). Conclusion: Those findings indicate that the application of sling exercise in the forward head posture can be a good program to maintain the right posture and improve or prevent an abnormal posture and raise a need for more clinical applications and ongoing researches.

경추 정면 방사선검사시 하악골, 후두골의 겹침방지, 경추 추체의 배열 및 관절의 형태 등을 관찰하기 위하여 X선 입사각을 머리 방향으로 $15{\sim}20^{\circ}$를 주고 있는 것이 보편적이다. 하지만 한국인의 체형에 맞는 입사각에 대한 연구는 거의 이루어지지 않고 있다. 이에 본 연구에서는 한국인에 적합한 입사각을 찾고, 방법을 제시하는데 목적이 있다. 입사각을 측정하기 위하여 서산에 위치한 S병원을 내원한 환자 1,044명을 대상으로 하였으며, 제 2번~제 5번 경추의 길이, 피사체-영상판 거리(OID), 제2번경추(axis)의경사도, 초점-영상판 간거리(FID)를 측정하였으며, 연령대 성별에 대한 평균값을 측정하여 적용공식에 의하여 입사각을 산출하였다. 경추 제2번~제5번의 평균길이는 6cm 이였으며, 10대부터 20대까지는 경추의 길이가 커지고 30대 이후로는 경추의 길이가 작아졌으며, 남성과 여성의 차이는 약 1cm 차이가 나타났다(p<.001). OFD는 연령대, 성별과 상관없이 거의 같은 값이 측정이 되었다. 제2번 경추(axis)의 경사도는 10대와 20대는 경사도가 증가하였지만, 30대 이후로는 작게 나타났다. 또한 남성과 여성은 약 $2^{\circ}$차이가 났다(p<.001). FID의 측정 결과, 연령대, 성별과 상관없이 거의 같은 값이 측정되었으며, 이 값으로 입사각을 측정한 결과, 10대는 $15.9^{\circ}$, 20대 $16.9^{\circ}$, 30대 $16.6^{\circ}$, 40대 $16.2^{\circ}$, 50대 $15.9^{\circ}$, 60대 $14.5^{\circ}$로 측정되었다. 10대와 20대까지 입사각이 증가하였지만, 30대 부터는 입사각이 작게 나타났다. 또한 10대는 남성과 여성이 같은 값으로 측정이 되었고, 20대부터는 남성과 여성이 $2^{\circ}$ 차이가 나타났다. 입사각과 제 2번~제 5번 경추의 길이측정, OID, 제 2번 경추의 경사도, FID와의 상관관계를 실시하였고, 입사각과 모두 유의한 상관관계가 나타났다(p<.001). 본 연구에서 경추의 평균 길이, OID, FID, 제2번 경추(axis)의 경사도에 따라서 입사각이 다르게 나타났고, 성별과 연령에 따라 입사각이 다른 것을 알 수 있었다. 그러므로 경추 정면검사 시 연령, 성별을 고려하여 입사각을 설정하면서 검사를 시행하여야 함이 사료되며, 향후 경추검사의 입사각을 설정할 때 참고 자료로 이용될 것으로 기대된다.

This study compared the stability of the cervical spine according to the presence of neck pain and deep neck flexor performance. Thirty subjects with neck pain, and thirty subjects without neck pain were recruited for this study. The Cranio-cervical flexion (CCF) test was applied using a pressure biofeedback unit to classify the subjects into four subgroups; no cervical pain and good deep neck flexor performance (NG group), no cervical pain and poor deep neck flexor performance (NP group), cervical pain and good deep neck flexor performance (PG group), and cervical pain and poor deep neck flexor performance (PP group). The head sway angle was measured using a three-dimensional motion analysis system. A 3-kg weight was used for external perturbation with the subject sitting in a chair in the resting and erect head positions with voluntary contraction of the deep neck flexors. A one-way analysis of variance (ANOVA) was performed with a Bonferroni post hoc test. The deep neck flexor performance differed significantly among the four groups (p<.05). The NG group had significantly greater deep neck flexor performance than NP and PP groups. The stability of the cervical spine also differed significantly among the four groups in the resting head position (p<.05). The head sway angle was significantly smaller in NG group as compared with the other groups. The PP group had the greatest head sway angle in the resting head position. However, there was no significant difference in the stability of the cervical spine among the groups in the erect head position with voluntary contraction of deep neck flexors (p=.57). The results of this study suggest that the deep neck flexor performance is important for maintaining the stability of cervical spine from external perturbation.

This study examined the effects of stretching and sling stabilizing exercises on changes in the angle of the cervical spine in military neck patients. The subjects were 20 adults diagnosed with a military neck(male:10, female:10) and they were randomly and equally assigned to a stretching exercise group and a sling stabilization exercise group. The total study period was four weeks. The intervention was applied three times per week for 60 minutes per each time. Before conducting the exercise, X-ray of each group was photographed to measure craniospinal angle(CVA) and cranial rotation angle(CRA). According to the result of comparing the two groups in changes in the cervical spine angle, there was no significant difference, and the result of comparing pre- and post-intervention was that there was significant change in CVA and CRA in the stretching group (p<.05) but there was no significant change in CVA and CRA in the sling stabilization exercise. Such result suggests stretching exercise is good for improving a military neck and stretching is more effective than sling in the therapeutic intervention for a military neck.
