Abstract: Objective? To?explore?the?clinical?features?of?metabolic?bone?disease?with?fracture?in?preterm?infants.? Method? The?clinical?data?of?metabolic?bone?disease?with?fractures?in?6?neonates?admitted?from?January?2016?to?April?2020?were? retrospectively?analyzed.?Results? Among?the?6?newborns?(5?boys?and?one?girl),?the?median?gestational?age?was?27.1?weeks,? and?the?median?birth?weight?was?900?g.?Among?the?6?newborns,?multiple?costal?fractures?occurred?in?one?case,?left?humeral? fracture?occurred?in?one?case,?left?femoral?fracture?occurred?in?two?cases,?femoral?and?humeral?fracture?occurred?in?two?cases,? and?right?humeral?fracture?occurred?in?one?case.?The?blood?phosphorus?of?the?6?newborns?were?all?<1.8?mmol/L,?and?the?blood? alkaline?phosphatase?were?all?>600?IU/L,?and?the?blood?calcium?were?in?the?normal?range.?All?the?6?neonates?were?complicated? with?retinopathy?of?prematurity?and?bronchopulmonary?dysplasia,?and?one?was?complicated?with?necrotizing?enterocolitis.?After? active?treatment?with?calcium,?phosphorus?and?vitamin?D3,?6?neonates?were?discharged?from?hospital?after?recovery?from?fracture.?
