The effects of immobilization subsequent to the repair of clean-cut tendon injuries on distal radius bone mineral content

BACKGROUND We investigated the changes of bone mineral density at distal radius and ulna in patients with volar wrist clean-cut tendon(s) injuries that were treated by early primary repair and passive mobilization. METHODS Fifteen patients with non-dominant hand injury (group I), 12 patients with dominant hand injury (group II) and 15 healthy volunteers serving as the control group (group III) were enrolled into this study. Side to side bone mineral component differences (SSD) of the proximal, middle and ultradistal radius that were obtained at 6th week and 4th month after operation were statistically compared. RESULTS In comparison with the control group, SSD measurements of the middle and proximal subregions of group II at the 6th week were significantly decreased (p<0.01 and p<0.001). The decreases were 8.9 and 8.6% respectively. Similarly, the 4th month SSD measurements of the middle and proximal subregions of group II were also significantly decreased compared to group III (p<0.001). The decreases were 10.2% and 7.7%, respectively. In group I, except a 7.4% decrease at the middle subregion of the radius at 4th month, there was no significant difference in SSD measurements as compared with the control group. CONCLUSION Results of our study indicate that there is a considerable bone loss of distal radius in patients who are surgically treated for acute clean-cut tendon(s) injuries at the volar wrist level.

Tendon tamiri sonrasý immobilizasyonun distal radius kemik mineral içeriðine etkisi

AMAÇ Önkol voler yüzde düzgün tendon yaralanmasý olan olgularda erken primer tamir ve pasif hareket sonrasý distal radiusta meydana gelen kemik mineral yoðunluðundaki deðiþimin araþtýrýlmasý. GEREÇ VE YÖNTEM On beþ dominant olmayan el yaralanmasý olan hasta (grup I), 12 dominant el yaralanmasý olan hasta (grup II) ve saðlýklý gönüllülerden oluþan 15 kiþilik kontrol grubu (grup III) çalýþmaya alýndý. Ameliyattan sonra 6. haftada ve 4. ayda elde edilen önkol proksimal, orta ve ultradistal bölgelerin yan-yana kemik mineral içeriðindeki deðiþimler (SSD) istatistiksel yöntemlerle karþýlaþtýrýldý.
BULGULAR Kontrol grubu ile kýyaslandýðýnda, grup II olgularda altýncý haftada radiusun proksimal ve orta bölgelerindeki SSD ölçümleri anlamlý derecede azaldý (p<0,01 ve p<0,001). Bu azalma sýrayla %8,9 ve %8,6 oranýndaydý. Benzer þekilde, kontrol grubu ile kýyaslandýðýnda, grup II olgularda dördüncü ay radiusun proksimal ve orta bölgelerindeki SSD ölçümleri anlamlý derecede azaldý (p<0,001). Bu azalma sýrayla %10,2 ve %7,7 olduðu kaydedildi. Grup I’de 4. aydaki radius orta kýsým SSD ölçümündeki %7,4 azalma hariç tutulursa, kontrol grubuna kýyaslandýðýnda SSD ölçümlerinin anlamlý farklýlýðý yoktu. SONUÇ Önkol voler yüzde düzgün tendon yaralanmasý olan olgularda erken primer tamir ve pasif hareket sonrasý distal radiusta meydana gelen kemik mineral yoðunluðunda anlamlý derecede azalma olabilmektedir.
