Die drukspanning wat nodig is om die trabekulere been van die femurnek, by pasiente met femurnekfrakture, te laat swig, is 60% minder as die wat nodig is om dieselfde resultaat by pasiente met heuposteoartrose te verkry. Die kompressiesterkte van die trabekulere been toon ’n redelike korrelasie (r = 0,58) met die relatiewe digtheid van die been, ’n Analise van die helling van die spanning-vervormingkurwes en ’n bepaling van die elastisiteitsmodulus van die trabekulere been toon dat pasiente met femurnekfrakture se been 30 - 60% meer elasties is as die van pasiente met heuposteoartrose. Sowel die sterkte as die elastisiteit van die trabekulere been kan dus ’n rol in die evolusie van fermurnekfrakture speel
