title: Complications with infection and foreign body reaction after silicon implant arthroplasty in the second metatarsophalangeal joint in an adolescent: a case report.
abstract: A 21-year-old otherwise healthy male was referred to our clinic due to severe pain, deformation, development of fistules, and swelling of the second metatarsophalangeal joint of the right foot. He presented a history of two previous operations. At the age of 13, a 2-cm. resection of the distal part of the proximal phalanx was performed due to severe hammertoe deformity. At the age of 19, a partial phalanx resection and implantation of a silicon elastomer ball-shaped joint spacer was performed due to second metatarsophalangeal joint instability. After this operation, the patient suffered from fistules that appeared in the second metatarsophalangeal region. Following referral to our clinic, the patient was operated on. The proximal phalanx was removed along with the prosthesis which had slipped from the metatarsophalangeal joint into the proximal phalanx with the ends of the prosthesis perforating the skin. Debridement of infected tissue and implantation of gentamicin containing beads were performed. Bacterial specimens revealed growth of coagulase-negative staphylococci. Microscopic examination of the debrided tissue showed signs of acute and chronic inflammation. Postoperatively, the patient was treated with antibiotics and healing was uneventful. This case advocates the need for proper selection criteria and strict indications in patients with joint disease needing an arthroplasty.
