CLINICAL ANATOMY OF THE PRETENDINOUS BANDS IN DUPUYTREN'S DISEASE

The special clinical aspect of Dupuytren's disease is characterized by thickening and contracture of the fibrous pretendinous bands on the palmar surface of the hand and fingers. There are also presented firm nodules and atrophic grooves or pits in the pits in the skin of the palm of the hand. We analyzed the frequency of location of the contracture of the fibrous pretendinous bands, on one consecutive series of 200 cases. Only 2.5% of the cases were female. The bilaterality of Dupuytren's disease was evident in 53% of the cases. 26.5% of single affected hands were right and 20.5% were left. A percent of 73.5% of cases showed only one fibrous pretendinous band; 26.5% of cases showed association of two or three fibrous pretendinous band. The whole study material revealed the location of the fibrous pretendinous band as follows: 0.5% thumb; 1% index finger;15% middle finger; 87% ring finger and 25.5% little finger. The most common combination of affected fingers are in: 16.5% ring finger and little finger; 75% middle finger and ring finger; 2.5% middle finger, ring finger and little finger; 0.5% thumb and index finger. These data are important for the hand surgery. (Supported by CNMP 62054/2008).
