Traditionally, intercalary allograft reconstruction after tumor resection has had a high rate of complications, particularly nonunion. Plate and intramedullary nail fixation have been used alone and in combination to improve union rates. This study sought to evaluate a new technique that uses a magnetic growing intramedullary nail to compress the osteotomy sites to aid in healing and to answer 2 questions: (1) What is the union rate and the time to union when using magnetic growing intramedullary nails? (2) What complications occur with this technique? Eight patients with 15 osteotomy sites with a minimum follow-up of 14 months were retrospectively reviewed. Seven of the 8 patients underwent initial reconstruction with the magnetic nail, whereas 1 patient underwent treatment of a nonunion that occurred with prior carbon fiber nail fixation. Twelve of the 15 osteotomy sites had healed by an average of 9 months. Nonunions occurred in 2 patients with an associated failure of the hardware. One of these patients healed after revision surgery. Of the patients who healed at both sites, 1 had a fracture through the allograft, 1 had backing out of a locking screw that required removal, and 1 required a manipulation under anesthesia of the knee. Two patients underwent successful limb lengthening needed because of an expected limb-length discrepancy after healing occurred. Use of growing intramedullary nails in compression mode led to an 87% union rate at final follow-up with acceptable complications. This technique provides a viable alternative to standard nail and plate fixation when intercalary allografts are used. [Orthopedics. 201x; xx(x):xx-xx.].

In many cases, the existing locking bolts and screws in intramedullary nails do not provide sufficient stability. Due to the play between screw and nail, the reduction can be lost and the ...

The use of nails that are inserted into bone cavities in order to keep fractured bones together.
Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms). The majority of intramedullary spinal tumors are primary CNS neoplasms including ASTROCYTOMA; EPENDYMOMA; and LIPOMA. Intramedullary neoplasms are often associated with SYRINGOMYELIA. The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.
