Embodiments herein are generally directed to extendable rods for use in orthopedic assemblies. In some embodiments, these implants may be used in conjunction with procedures to treat spinal deformities, including, but not limited to, early onset scoliosis.

Orthopedic extendable rods

An implantable growing rod assembly adapted to be secured along a length of a spine for treating deformities of the spine. The assembly includes a housing, a fixed rod extending along a longitudinal axis away from the housing, and an expansion rod extendible from the housing along the longitudinal axis. A driver assembly is fixed to the housing and adapted to translate the expansion rod along the longitudinal axis.

Growing rod for treating spinal deformities and method for using same

A growing rod adapted to be secured along a length of a spine for treating deformities of the spine. The growing rod comprises a base rod, an extendible rod having a proximal portion that is slidably coupled to the base rod and arranged with a gear rack, and a distraction unit. The distraction unit includes a housing attached to the base rod, a rotatable drive interface accessible by an external driver from outside of the housing, and a drive gear mechanism housed within the housing and coupled to the rotatable drive interface and the gear rack such that rotation of the rotatable drive interface causes linear movement of the extendible rod through the gear rack.

In some embodiments, provided is an apparatus including a first elongated member, the first elongated member including a distal end and a proximal end. The distal end of the first elongated member is coupled to a first bone portion during use. The apparatus further includes a second elongated member including a distal end and a proximal end. The distal end of the second elongated member is coupled to a second bone portion during use. The proximal end of the second elongated member comprises a surface that is shaped complementary to a surface of the proximal end of the first elongated member. The apparatus still further includes a locking mechanism coupling the proximal end of the first elongated member to the proximal end of the second elongated member. The locking mechanism is adjustable from an unlocked position to a locked position such that, when the locking mechanism is in the unlocked position, the first elongated member is angularly movable relative to the second elongated member, and when the locking mechanism is in the locked position, the complementary shaped surfaces of the first elongated member and the second elongated member are directly connected and the relative angular position of the first elongated member and the second elongated member is substantially fixed.
