摘要： A spinal fixation construct (1) for aligning vertebral bodies includes a bone screw (40), a spinal rod (30), a flexible member (20) and a fixation member (10). The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion (16) and a head portion (14) defining a hole (14a) therethrough. A portion of the flexible member extends through the hole of the head portion.

摘要： A growing spinal rod system is configured to grow in response to the growth of a patient. The growing spinal rod system includes a housing, a spacer, and a sliding spinal rod. The housing includes a stepped passage therethrough. The spacer is disposed within the stepped passage and defines a through hole. The spacer includes a plurality of ribs biased inwards and into the through hole. The sliding spinal rod is slidably inserted through the through hole of the spacer. The sliding spinal rod moves the plurality of ribs outwards. The plurality of ribs permits the sliding spinal rod to extend from the housing and inhibit the sliding spinal rod from retracting into the housing.
