Limb Salvage Using Non‐hinged Endoprosthesis and Staged Correction of Leg‐length Discrepancy for Children with Distal Femoral Malignant Tumors

Abstract: ObjectiveLimb salvage in pediatric patients remains a challenge. We describe a staged strategy. The procedure includes: (i) tumor removal and non‐hinged static endoprosthesis reconstruction; (ii) leg length discrepancy (LLD) correction by shoe lift or distraction osteogenesis; and (iii) maturity reconstruction by regular endoprosthesis. The aim of the study was to investigate the results of non‐hinged static megaprosthesis reconstruction and staged LLD correction in the treatment of malignant tumors in the dis… Show more

“…Other prostheses included were Repiphysis, MUTARS, Kotz, LUMiC, RESTOR, Lewis, HMRS and Non Hinged CCK megaprosthesis ( Table 2 ). Six studies used non-expanding prostheses [ 17 , 18 , 22 , 25 , 26 , 29 ], while the remaining eleven studies involved expanding prostheses [ 14 , 15 , 16 , 19 , 20 , 21 , 23 , 24 , 27 , 28 , 30 ]. Some studies used an expanding Stanmore prosthesis; however, three studies used custom made non-expanding Stanmore implants [ 17 , 18 , 22 ].…”

“…Osteosarcoma (OS), the most common primary sarcoma affecting the lower extremities in skeletally immature individuals, has attracted considerable attention in various studies in recent decades 10 , 11 , 12 . Currently, open physes are often regarded as a natural barrier to osteosarcoma invasion because of their high avascularity, continuity, and cell density, and few people expect them to have a “gap” 3 , 13 . However, a series of interesting phenomena were observed in our clinical works: it seems that more metaphyseal osteosarcomas tend to penetrate the growth plates through intercondylar regions rather than bilateral condyles in proximal tibias and distal femurs.…”

“…The UHMWPE block could reduce the stress shielding because of the low elastic modulus which is similar to the bone ( Sun et al, 2015 ). And the universal design of the UHMWPE block has a predetermined size, which brings a large convenience for clinic applications ( Ji et al, 2019 ). However, the preset size cannot be changed, making it impossible to match bone defects of varying sizes.…”
