Spinal Infection Management With Structural Allograft

Summary

Background. Bone infections can involve the vertebral column, intervertebral disc space, spinal canal and soft tissues, can generate neurological deficit in addition to the destruction of the bone that causes functional disability. Vertebral osteomyelitis is the most frequent, affecting 2 to 7 patients per 100,000 habitants. Management is bone debridement and bone reconstruction.

Objective. Demonstrate that the use of bone allograft is a functional method to stabilize the spine after a bone spinal infection Material and methods. Patients with vertebral bone destruction are included in two groups. Bone allograft group will receive bone structural allograft; Auto and allograft group will receive bone structural allograft plus autograft. The bone reconstruction will be performed in a one-time surgical procedure. Bone consolidation, pain, functionality, and spine deformity will be evaluated.

Conditions

• Bone Diseases, Infectious
• Disease of Bone
• Syndrome
• Spine Infection
• Allografts
• Bone Graft; Complications, Fracture

Interventions

DEVICE

Bone allograft

All patients will undergo the same surgical procedure consisting of open surgery, more debridement of infected and devitalized tissue, as well as corresponding bone resection. For the identification of the microorganism, biopsies will be performed by puncture guided by CAT and / or fluoroscopy, and culture and antibiogram will be performed in case of not obtaining enough material for this, at the time of the surgery samples will be sent to perform the same procedure. We will use the appropriate antibiotics, according to infecting microorganism and result of antibiogram. We will include patients with infections with gram positive and negative microorganisms only. This patients will go stabilized with bone allograft only.
