Role of MRI in detecting early physeal changes due to acute osteoarticular infection around the knee joint: a pilot study.

Physeal changes of any aetiology in children are usually diagnosed once the deformity is clinically evident. Between January 2006 and June 2007, 15 children who suffered from acute osteoarticular infection around the knee joint were studied. They were called up for follow-up six months after the onset of infection. All patients were evaluated by clinical and roentgenographic examination before undergoing magnetic resonance imaging (MRI) study of both knees "with the unaffected knee serving as control". Abnormal findings in the physis, metaphysis and/or epiphysis on MRI were observed in five children. This group of five children was compared with the other ten children for clinical presentation and course of disease. We believe that MRI is a useful tool in the evaluation of growth plate insult in the early period following acute osteoarticular infection, and we can diagnose and prevent the catastrophic complications of the same.

Calcanisation of tibia using Ilizarov fixator in crush injuries of hindfoot: a new method.

Crush injuries of the foot are one of the most difficult and challenging tasks for a trauma surgeon to manage in terms of limb salvage and provision of a painless functional foot. Injuries to the foot, especially the hindfoot, account for almost 24.6% of all the warfare injuries in Afghanistan, of which more than 70% end in amputation for various reasons. We devised a method using the principles of Ilizarov's distraction osteosynthesis to salvage limbs with bony defects in the hindfoot which otherwise were candidates for amputation. The procedure is done in two stages. Initially, the ring fixator is applied for the soft tissue reconstruction and infection control, and the next stage consists of percutaneous "inverted L"-shaped osteotomy in the posterior half of the lower tibia. The study included 32 patients with hindfoot crush injuries involving talus, calcaneum, a combination of both, or even involving the adjacent tarsal bones. All these crush injuries were classified using the Gustilo and Anderson classification. The postoperative functional assessment of the feet was done using the Maryland Foot Score system with a minimum follow-up of four years. We had good results in 53%, fair in 34% and failure in 13% of our cases. The complications of this procedure were the same as with the use of the ring fixator elsewhere in the body. This method provides a technique to salvage the foot and produce a painless, stable, fused foot in one of the most difficult settings of a hindfoot crush injury.
