The Inter-Os Limb Lengthener is an implantable device for distraction osteogenesis techniques in the femur. The Inter-Os Limb Lengthener is used to treat conditions for limb length deficiencies involving the femur. The types of deformities that fall into this category are: Traumatic deformities, growth deformities, deformities secondary to tumors and infections, and congenital deformities. The Inter-Os Limb Lengthener is intended to be used in the upper leg bones of the appendicular skeleton. The Limb Lengthener is not intended to be used for the spine. The Inter-Os Limb Lengthener is intended for single use and is not meant for repeat sterilization and implantation. The device is to be removed after consolidation of the bone is complete. It is to be used with other commercially-available accessory devices, such as bone screws for fixation to the bone surface. Bone cement is not to be used to fixate the device to the bone; however, commercially-available bone cement may be used on the undersurface of the device to level or stabilize it on a curved surface, or bone cement may also be used to fix the gear in position during the consolidation period.

The Inter-Os Limb Lengthener is an implantable device used to treat conditions where bone length is deficient. It is used for distraction osteogenesis techniques in the femur and is intended to be implanted by orthopedic surgeons. The device is removed after distraction is complete. It features two telescoping component bone plates that are distracted apart by a threaded drive shaft. Activation of the drive shaft is by means of a transcutaneous pin, which may be removed once the distraction phase is complete. The Activation Pin and the drive shaft are articulated using an internal gear. All of the components of the Inter-Os Limb Lengthener are fabricated from stainless steel. The Inter-Os Limb Lengthener is intended to be sold non-sterile. It is a singleuse device. Sterilization instructions are included in the labeling.

The Inter-Os Bone Generator™ is an implantable device for distraction osteogenesis techniques in the facial bones implanted by a surgeon. Distraction osteogenesis involves making an osteotomy through the bone and then slowly moving the bone ends apart. The result is a stretching of the bone callus so that new bone is generated in the gap. This technique is well-established and follows the principles of Mizarov. (See Addendum A Osteogenesis Research Bibliography) The Inter-Os Bone Generator™ is used to treat conditions where bone growth is deficient. The types of deformities that fall into this category are: various forms of otomandibular syndrome, hemifacial microsomia, Treacher-Collins syndrome, condylar agenesis, craniosynostosis, Apert's syndrome, Crouzon's syndrome, Pfeiffer's syndrome, etc. The application of the device is done in place of bone grafting to augment deficient areas of bone growth. The advantages of distraction bone generation are that the patient is spared the morbidity of additional surgical sites and native autogenous bone is formed. The device can also be used in post-traumatic deformities, such as condylar fractures in children. The Bone Generator™, therefore, is intended to be used in the various bones of the craniofacial region, such as the mandible, zygoma, maxilla, frontal bone, and the temporal bone. It is not the current intended use to apply the Bone Generator™ to the long bones of the limbs or in the spine, but only to the bones of the craniofacial region. The Bone Generator™ is intended for single use and is not meant for repeat sterilization and implantation. The device is to be removed after distraction stabilization is complete. It is to be used with other commerciallyavailable accessory devices, such as bone screws for fixation to the bone surface. The device is not meant to be fixated to the bone with bone cement, however, it is possible that commercially-available bone cement may be used on the undersurface of the device to level or stabilize it on a curved surface.
