Comparison of Percutaneous and Open Decompression in the Treatment of Carpal Tunnel Syndrome / 대한정형외과학회잡지

Carpal tunnel syndrome is the most common peripheral nerve entrapment syndrome that characterized by pain, especially in night, sensory disturbance in median nerve dermatome of the hand, and thenar muscle atrophy. Open decompression was a treatment of choice, when operative intervention is necessary. But, endoscopic or percutaneous decompression is introduced recently. Authors analyzed 21 cases of open decompression and 22 cases of percutaneous decompression and they could be follow up over 6 months at Dept. of Orthopedics, Chonnam University Hospital from June 1990 to January 1995. The results are as follows. 1. There were no difference in age, sex, lesion side, symptoms duration until operation, etiology and occupation between percutaneous and open decompression. 2. There were excellent or good results in clinical symptom in 19 cases(90%) of open procedures and 19 cases(86%) of percutaneous procedure and more rapid relief of the pain, and grip power in percutaneous procedure than open procedure. 3. The EMG, recorded at 1 week, 4 weeks, 3 months and 6 months after operation, revealed improvement in sensory than motor function. There was more rapid recovery in percutaneous procedure than open procedure especially latency and amplitude of sensory nerve. There were 2 cases in open procedure and 3 cases in percutaneous procedure who did not respond to treatment. As a result, percutaneous procedure was more simple and rapid recovery than open procedure in clinical progressions and EMG reports, but recovery rate of symptomatic relief was similar. Therefore percutaneous procedure is thought to be more reasonable method in the treatment of carpal tunnel syndrome if surgical intervention is indicated.

Bone Mineral Density of Lumbar Spine Measured by DEXA and QCT / 대한정형외과학회잡지

To study the relationship between the bone mineral density measured by DEXA and QCT methods and to study the factors influencing on the value, bone mineral density in 208 patients with low back pain were measured by the two methods and compared statistically. Ages were varied between 17 to 79(Av. 46.7) years and male and female were 86 and 122. The results of this are as follows; 1. The values of DEXA and QCT showed statistically significant relationship(γ=0.58) as a whole. And bone mineral density in L2, L3 and L4 showed no difference in both groups. 2. Bone loss by aging(per year) in male and female was 0.99% and 1.06% by DEXA, 0,99% and 1.41% by QCT. 3. Body height and weight showed no significant influence of the value in two methods. 4. In body mass index over 27.5, the value measured by QCT was influenced to be diminished while that of DEXA was not influenced. 5. The value by QCT was influenced to be diminished by the increase of age especially over 50 years old in both sex. While the value by DEXA was influenced to be lowered than expected in female over 50 years old. It is concluded that the methods of measurement of bone mineral density have their limitation depend on the age, sex and mass index.
