Extracorporeal shockwave for hip necrosis in XXXX .

@entity1 @entity1252 @entity158 @entity2530
@entity1 with @entity1252 ( @entity1252 ) frequently received corticosteroid therapy, resulting in @entity2530 of the femoral head (ONFH). Prior studies demonstrated the effectiveness of extracorporeal shockwave treatment (ESWT) for ONFH.. This study evaluated the effectiveness of ESWT for ONFH in @entity1 with @entity1252 . We studied 39 @entity1 , including 15 @entity1 with @entity1252 (26 hips) and 24 controls (29 hips). To each affected hip we applied ESWT (6000 impulses at 28 kV in a single session). @entity1 were ambulated with partial weight bearing for 4-6 weeks. The primary endpoint was the need for hip replacement. The secondary endpoints were improvement in @entity158 and function and image changes on X-ray and MRI. @entity1 received total hip replacement in 12% of @entity1 with @entity1252 and in 14% of controls (P = 0.802). There was no statistically significant difference in @entity158 scores (0.86 vs. 0.89; P = 0.467) and function scores (89% vs. 91%; P = 0.194) between @entity1 with @entity1252 and controls. @entity1252 response to ESWT for ONFH is comparable with ONFH in @entity1 without @entity1252 .
