The aim of this study was ultrasonographic evaluation, subjective and objective or quantitative, of the SDFT core lesion in donkeys treated with intralesional injection of PRP. Subjective evaluation was performed by assessment of fiber echogenicity score (FES) and fiber alignment score (FAS). Quantitative evaluation was performed by gray scale histogram analysis and measuring of core lesion cross section area (CSA). The present study was carried out on two groups (group-I) 12 donkeys treated by intratendenious injection of freshly prepared (PRP) and (group-II) 7 donkeys as control group and subjected to intratendenious injection of normal saline (Placebo). Ultrasonographic assessment were performed before induction, 5th, 15th, 30th, 45th, 60th and 90th days post induction of core lesion. The PRP treated group revealed significant (p ≤ 0.05) improvement of FES and FAS at 15th, 30th, 60th and 90th days and at 30th days post induction, respectively. Moreover, there was significant improvement of the core lesion CSA and the mean gray scale histogram during all time points to reach near to the normal value at the end of the study. The mean gray value of the PRP treated group was significant (p ≤ 0.05) higher than that of control group at all-time points of the experiment. The obtained subjective and quantitative ultrasonographic assessments in the present investigations proved that these parameters could be valuable in the evaluation of SDFT core lesions and monitoring the treatment of tendopathy in equines. |
