  • The pelvic distraction-stress radiographs of 50 clinically normal Korean Jindo which confirmed to have non-dysplastic hip joints on the ventrodorsal extension view, were investigated to evaluate the passive coxofemoral joint laxity as quantified by the distraction index. The synovial fluid cavitation of the unilateral coxofemoral joint was detected in 8 dogs, and distraction index was not measured in theses cavitated joints. The distraction index measured minimally 0.20, and maximally 0.74. The medial distraction index for the dog examined was 0.42, and 75th percentile distraction index was below 0.50.

  • Background Craniosynostosis management using distraction osteogensis represent a challenge for surgeons due to the great variability of the skull deformity even within the same etiology. The ability to apply the simulation surgery for improving the preoperative planning for distraction osteogensis could improve the results.Planning and Simulation 14 patients presented with craniosynostosis had been subjected to simulation surgery prior to real surgery. 3D CT scans was obtained upon patient admission. Adjustment of all skull position to Frankfort horizontal plane was done. 3 different distraction osteogensis plans were done for each patient according to the skull morphology. For each plane, movement for each bone segment was done according to the pre-planned distraction vectors. Also the distances of distractions were pre-determined according to the cephalic index as well as brain volume. Intraoperatively, we choose the most appropriate plan for the patient by the surgeon. At the end of distraction, 3D CT scan was obtained, and was compared to the simulation plan. Also the distance and the direction of distraction was compared to that of the plan. Accordingly, the distance was almost matching that of the simulation surgery, however the vector of distraction was not matched.Conclusion Preoperative stimulation planning for craniosynostosis patient is very valuable tool in the surgical management of craniosynostosis patients.

  • Objective : Vertebral distraction is routinely performed during anterior cervical discectomy and fusion (ACDF). Overdistraction can injure the facet joints and may cause postoperative neck pain consequently. The purpose of this study was to investigate the clinical relevance of distraction force during ACDF. Methods : This study included 24 consecutive patients with single level cervical disc disease undergoing single level ACDF. We measure the maximum torque just before the the arm of the Caspar retractor was suspended by the rachet mechanism by turning the lever on the movable arm using a torque meter. In order to turn the lever using the torque driver, we made a linear groove on the top of the lever. We compared the neck disability index (NDI) and visual analogue scale (VAS) scores between the high torque group (distraction force>6 $kgf{\cdot}cm$) and the low torque group (distraction force${\leq}6kgf{\cdot}cm$) at routine postoperative intervals of 1, 3, 5 days and 1, 3, 6 months. Results : The VAS scores for posterior neck pain had a linear correlation with torque at postoperative 1st and 3rd days ($y=0.99{\times}-1.1$, $r^2=0.82$; $y=0.77{\times}-0.63$, $r^2=0.73$, respectively). VAS scores for posterior neck pain were lower in the low torque group than in the high torque group on both 1 and 3 days postoperatively ($3.1{\pm}1.3$, $2.6{\pm}1.0$ compared with $6.0{\pm}0.6$, $4.9{\pm}0.8$, p<0.01). However, the difference in NDI scores was not statistically significant in all postoperative periods. Conclusion : Vertebral distraction may cause posterior neck pain in the immediate postoperative days. We recommend not to distract the intervertebral disc space excessively with a force of more than 6.0 $kgf{\cdot}cm$.

  • Purpose: This study was conducted to determine how a manual therapy (joint mobilization and flexion-distraction technique) would affect pain and function with the chronic low back pain. Methods: Thirty patients were assigned to either the experimental group (n=15) or the control group (n=15). Patients in the experimental group performed joint mobilization and flexion-distraction technique. Patients in the control group performed spinal decompression therapy. Both exercises were performed for three days per week, for a period of six weeks. Pain was measured by the visual analogue scale (VAS) and functional disability was measured using the Oswestry disability index (ODI). A paired t-test was used for identify differences before and after treatment, and an independent t-test was used to identify differences between treatment groups. Results: In the within group comparison, the experimental group and control group differed significantly for all variables (p<0.05). However, no significant differences were observed in any variables between groups (p>0.05). Conclusion: The above results confirmed that it is necessary to confirm the various benefits of therapy with the joint mobilization and the flexion-distraction technique. The findings of the concerned study will be useful to doctors applying therapy to treat patients with the chronic low back pain.

  • Hips of the Golden and Labrador retrievers in Korea were evaluated with the University of Pennsylvania Hip Improvement Program (PennHIP) and the severity of joint laxity and degenerative joint disease (DJD) were compared to the PennHIP database. The distraction index (DI) of domestic Golden and Labrador retrievers was significantly higher than the DI of the PennHIP database. In the two breeds, the prevalence of DJD increased according to the DI. However, the severity of DJD did not show a positive correlation with the DI. Overweight dogs and dogs kept indoors showed more severe DJD and more prevalence of clinical signs. This report is thought to be the first case presentation of a large population of Golden and Labrador retrievers in Korea and the findings are representing the overall level of canine hip dysplasia (CHD) of domestic Retrievers, as the PennHIP method was not available in Korea until 2001. We can respect that the stock of retrievers can have a tighter hip joint through control of CHD using an accurate diagnostic method keyed to a phenotype especially concern for joint laxity using PennHIP method and an organized screening program. The clinical manifestation of dysplastic dog can be reduced through control of bodyweight and the environment with regular monitoring the hips with concern for joint laxity using PennHIP method.

  • The purpose of the present study was to determine the effect of a 4 week course of Cox distraction manipulation (CDM) combined with therapeutic modalities on the treatment of patients with L4-5 herniated nucleus pulposus (HNP). A total of 15 patients with L4-5 HNP (mean age, 37.76 years; age range 20-50years) participated in the study. A 4 week course of CDM combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and three times per week for two additional weeks. The entire treatment consisted of 18 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and oswestry disability index (ODI) at pre-intervention, after two weeks treatment sessions, and at discharge (after 18 treatment sessions) were analyzed. Comparisons of changes in the disc herniation index (DHI) at pre-intervention and at discharge were analyzed using the paired t-test. There were significant improvements in the outcome measures of MS Ibs, SLR test, and ODI score after 2 weeks and 4 weeks sessions of CDM combined with therapeutic modalities as compared with the pre-intervention. However, no significant different pre-test and post-test DHI. CDM combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with L4-5 HNP.
