Safety of orthopedic implants in magnetic resonance imaging: an experimental verification.

Magnetic resonance imaging (MRI) is an indispensable tool for musculoskeletal imaging. The presence of metal, however, raises concerns. The potential risks are loosening and migration of the implant, heating of the metal with surrounding tissue, causing thermal damage, and artifactual distortion which compromise the diagnostic value of the procedure.

Medial approach for operative treatment of the widely displaced supracondylar fractures of the humerus in childre.

Twenty-seven widely displaced supracondylar fractures of the humerus in children were treated by open reduction and cross K-wire fixation by the medial approach over a 30-month period. The mean follow-up was 14 months, average age 8 years and the mean delay in presentation 49 hours. Medial approach provided an excellent view of the medial bone pathology via an internervous plane and enabled an anatomical reduction in all cases.

The Hoffa fracture: Three case reports.

Unicondylar fractures of the lower end of the femur are uncommon injuries that usually occur in the saggital plane 2. Coronal (tangential) plane fractures, first described by Hoffa in 1904, are unusual.(1,2, 3,4) We report our experience with three cases and the mechanism of injury is discussed.

A study of vascular injuries in pediatric supracondylar humeral fractures.

194 children with supracondylar fractures of the humerus were reviewed. Of the 49 children with Gartland grade III displacement, signs of vascular compromise were clinically suspected in 5 cases. Immediate open reduction, internal fixation and exploration were performed.

Surgical management of the severely displaced supracondylar fracture of the humerus in children.

We reviewed 44 children with a widely displaced supracondylar fracture of the humerus (Gartland grade III) treated with primary open reduction and cross pinning. The average age was 8 years and the mean delay in presentation was 34 h. Comminution of the medial supracondylar pillar was seen in 57% of the cases.
