The purpose of this study was to investigate the effect of traction and decompression therapies on the cervical muscle tone and disc height. The decompression group (n=16) received decompression therapy and Mckenzie exercises once a day and four times a week respectively, for three weeks. The traction group (n=15) also received traction therapy and Mckenzie exercises for the same period. Muscle tone was measured with a myotonometer, and the disk height was measured using magnetic resonance imaging (MRI), before the interventions. Three weeks later, we investigated the therapeutic effect by repeating these measurements. The difference in disk height between the two groups was not significant. There was a significant difference in the disk herniation index (p<.05). A significant difference was found only in the upper trapezius muscle after comparison of muscle tone and stiffness between the groups (p<.05). Findings from this study suggest that the decompression therapy is a more effective intervention for patients with cervical intervertebral disc herniation.

The dentigerous cyst is defined as a cyst that originates by the separation of the follicle from around the crown of an unerupted tooth. This is the most common type of developmental odontogenic cyst, making up about 20% of all epithelium-lined cysts of the jaws. Large dentigerous cysts are uncommon, but some cases are large cysts. The usual treatment for a dentigerous cyst is careful enucleation of the cyst together with removal of the unerupted tooth. Large dentigerous cysts also may be treated by decompression. This permits decompression of the cyst, with a resulting reduction in the size of the bone defect. The cyst can then be enucleated at a later date with a less extensive surgical procedure and important structures such as teeth and the inferior alveolar nerve can be preserved. These cases are large dentigerous cysts treated by decompression. Less extensive surgical procedures were used and some teeth were preserved.

The purpose of this study identify that spinal decompression therapy effect on and pain, length Of leg distance(LLD), and muscle power and flexibility in patient with low back pain. The participants is 20 female and male with low back pain, and participant assign to decompression therapy group and control group at random. The decompression therapy apply to 20 minute 3 time for a week during 4 weeks. The Measurement items is pain, LLD, and muscle power, flexibility. The comparison between the before and after was Wilcoxon's U test, and 2 group after spinal decompression therapy application compared Mann-Whithney U test. Spinal decompression therapy reduced statistically significance the pain, LLD, and increased statistically significance the muscle power and flexibility increased the muscle power(p<.05). This study showed that spinal decompression therapy does affect pain, LLD, and muscle power and flexibility in patient with low back pain.

Treatment of spontaneous retroperitoneal hemorrhage (SRH) is mainly conservative. However, if intra-abdominal hypertension (IAH) or abdominal compartment syndrome (ACS) develops, the treatment strategy should be more aggressive. Surgical decompression has been the gold standard; however, it is very invasive and highly morbid. Thus, percutaneous catheter drainage (PCD) has been introduced as an alternative therapeutic option. We report on a case of successful PCD for prevention of progression of IAH to ACS in a patient with SRH after coronary stent implantation. This case showed that PCD can be an efficacious and safe method for treatment of IAH with impending ACS.
