  • Objectives : The aim of this study is to investigate the state of cervical disc herniation according to the degree of cervical lordosis and age. Methods : 67 records of inpatients who were diagnosed with herniated intervertebral disc(HIVD) of the cervical spine were analyzed. Cobb's method, Jochumsen method and the Ishihara index were used to measure the degree of cervical lordosis. The state of the cervical disc was identified using magnetic resonance imaging(MRI) of the cervical spine. Then correlations among cervical lordosis, age and cervical disc herniation were analyzed. Results : Disc bulging was associated with hypolordosis and disc protrusion was associated with hyperlordosis and age. Disc extrusion was not associated with either cervical lordosis or age. The number of disc herniations in the cervical spine was correlated with age significantly, but not with cervical lordosis. Conclusions : Cervical disc herniation had a tendency to correlate with age and cervical lordosis, although this is not definite. Future studies that analyze more radiographic images of patients with HIVD of the cervical spine might be necessary to identify the influence of cervical lordosis on cervical disc herniation.

  • Objectives: This study was designed to investigate the correlation between cervical, lumbar lordosis and low back pain(LBP), sex, age and duration of LBP. Methods : Cervical, lumbar lordosis(by Cobb's Method) and Ferguson's angle were measured and evaluated in LBP group and control. Radiograph was taken in lateral direction, erect position. Cobb's angle between C1-C7, C2-C7, L1-L5, L1-S1 and Ferguson's angle were measured and investigated with statistical program. Results: 1. Cervical lordosis have no relation to LBP, sex and age. 2. Lumbar lordosis and Ferguson's angle have no relation to LBP and sex. 3. Cobb's angle L1-L5 have no relation to age. Lumbar lordosis from L1 to S1(Cobb's angle L1-S1) increased in old group(Age>40) compared to young group(Age${\leq}$40). 4. In LBP group, Cobb's angle L1-S1 have no relation to duration of LBP. Lumbar lordosis from L1 to L5(Cobb's angle L1-L5) decreased in acute LBP group compared to Chronic group. Conclusions : Cervical, lumbar lordosis and Ferguson's angle have no relation to LBP and sex. As far as age is concerned, old group have larger lumbosacral lordosis than young group. Acute LBP group have smaller lumbar lordosis(Cobb's angle L1-L5) than chronic group.

  • Study Design: Prospective cohort study. Purpose: To study clinicoradiological parameters of zero-profile cage screw used for anterior cervical discectomy and fusion (ACDF). Overview of Literature: Radiological parameters of various implants used for ACDF are available, but those for zero-profile cage are sparse. Methods: Patients with unilateral intractable brachialgia due to single-level cervical disc prolapse between April 1, 2011 and March 31, 2014 were included. Clinical assessment included arm and neck pain using visual analogue score (VAS) and neck disability index (NDI) scores. Radiological assessment included motion segment height, adjacent disc height (upper and lower), segmental and cervical lordosis, implant subsidence, and pseudoarthrosis. Follow-ups were scheduled at 1, 3, 6, 12, and 24 months. Results: Thirty-four patients (26 males, 8 females) aged 30-50 years (mean, 42.2) showed excellent clinical improvement based on VAS scores (7.4-0 for arm and 2.0-0.6 for neck pains). Postoperative disc height improved by 11.33% (p<0.001), but at 2 years, the score deteriorated by 7.03% (p<0.001). Difference in the adjacent segment disc height at 2 years was 0.08% (p=0.8) in upper and 0.16% (p<0.001) in lower disc spaces. Average segmental lordosis achieved was $5.59^{\circ}$ (p<0.001) from a preoperative kyphosis of $0.88^{\circ}$; at 2 years, an average loss of $7.05^{\circ}$ (p<0.001) occurred, resulting in an average segmental kyphosis of $1.38^{\circ}$. Cervical lordosis improved from $11.59^{\circ}$ to $14.88^{\circ}$ (p=0.164), and at 2 years, it progressively improved to $22.59^{\circ}$ (p<0.001). Three patients showed bone formation and two mild protrusion of the implant at 2 years without pseudoarthrosis/implant failure. Conclusions: The zero-profile cage screw device provides good fusion and cervical lordosis but is incapable of maintaining the segmental lordosis achieved up to a 2-year follow-up. We also recommend caution when using it in patients with small vertebrae.

  • Background: The purpose of this study is to compare axis change during cervical flexion and extension according to lordosis angle to patients with scoliosis. Methods: Movement axis change was estimated during cervical flexion and extension in twenty-four scoliosis patients with hypolordosis using radiography. Subjects were divided into mild lordotic curve group (MLCG, n=12, $34{\sim}25^{\circ}$) and severe lordotic curve group (SLCG, n=12, less $25^{\circ}$) according to cervical lordosis angle. Results: During cervical flexion, both group showed movement axis change to upper part of cervical vertebra and SLCG showed greater than MLCG but there is no significant difference. During cervical extension, SLCG showed greater than MLCG and there is significant difference. Conclusion: It is considered that cervical hypolordosis acts as important factor to scoliosis and degenerative joint disease because it leads to change of movement axis and central route of joint.

  • The purpose of this study was to investigate the effects of occipital bone stimulation by cervical stabilizing exercise on the muscle tone, stiffness, ROM, and cervical lordosis in patient with forward head posture(FHP). This study was a case study of a single patient with forward head posture. This study used a ABA' design, A and A' were the baseline phases and B was the intervention phase. The intervention was occipital bone stimulation by cervical stabilization exercise. It was administered once daily for 7 days. The therapist kept hands together, and placed the two index fingers under the subject's occipital bone. The subject performed the chin-in exercise with a maximum isometric contraction for 20 sec.The exercise was implemented by performing the movements 10 times as a set and repeating the set three times. The muscle tone was not significantly changed after intervention. However, the stiffness was decreased and lasted the effect lasted without intervention. The cervical flexion angle was increased, but the cervical extension angle was not significantly changed after the intervention. The left and right lateral flexion angles were increased and the effect lasted without any intervention. However, the left and right rotation angles were significantly changed after the intervention. Cervical lordosis increased not from $37^{\circ}$ to $41^{\circ}$ after the intervention. These results suggest that occipital bone stimulation by cervical stabilizing exercise had a positive effect on cervical stiffness, flexion and lateral flexion ROM, and lordosis in a patient with forward head posture.
