Change in MHIP score elements
TB, bone marrow oedema, gluteal tendinopathy, tendinopathy, fatty muscular atrophy
BONE MARROW OEDEMA, TROCHANTERIC BURSITIS, ATROPHIC
The MHIP score is calculated based on 5 elements although the total score reflects tendinopathy severity : gluteal tendinopathy rating (GT) and trochanteric bursitis (TB), cortical irregularity (CI) and bone marrow oedema (BO) and fatty muscular atrophy (FA) [Tendon related scores were similar between the CSI group and LR-PRP groups, with the CSI group showing a small reduction in GT scores (1.7 (SD 0.6) to 1.3 (SD 0.6)) but no change in TB scores and the LR-PRP group showing no change in GT scores but a small reduction in TB scores (2.0 (SD 1.0) to 1.6 (SD 1.1)) (supplementary tables S1 and S2).The bone related scores had the largest between group difference with CI increasing in the CSI group (0.3 (SD 0.6) to 0.6 (SD 0.6)) but decreasing in the LR-PRP group (0.6 (SD 0.7) to 0.4 (0.5)) and BO also reducing in the LR-PRP group (0.2 (SD 0.4) to 0 (SD 0)) (supplementary tables S1 and S2).Fatty atrophic muscular changes were the same in the CSI group pre- and post- treatment (0.6 SD 1.2) and similar in the LR-PRP group (0.5 (SD 0.9) to 0.6 (SD 0.9)) (supplementary tables S1 and S2). Figure 3 shows the pre and post MRI images from three participants who had improvement of more than 2 points in their MHIP scores.
