Abstract
This is a case report using a new technique designed to allow passage of a screw through a joint while simultaneously preserving the joint cartilage. A 58-year-old woman with diabetes with midfoot Charcot neuro-arthropathy underwent reconstruction, which included a medial column rodding. A headless 8.0-mm screw was inserted into the first metatarsal head coursing along the entire medial column after temporary removal of a portion of the osteochondral surface. This allowed the screw to be positioned perpendicular to the medial column joints. Serial radiographs were collected to evaluate alignment, stability, and osteochondral graft incorporation. The patient showed preservation of joint motion and function with complete osteochondral graft incorporation without evidence of joint degeneration or pain after 45 months of follow-up. This is the first study to present the use of a local osteochondral graft to allow passage of a large diameter screw in the foot. Although graft incorporation was complete, the situation regarding joint preservation remains unclear, but midterm follow-up shows promise.
