Case:Juvenile rheumatoid arthritis (JRA) is associated with severe flexion contracture of the knees disabling a patient's ability to walk. Although various treatment modalities are available in the literature, we report a 2-stage procedure in a case of a 22-year-old female JRA patient with bilateral severe flexion deformity of the knee: stage 1—correction of the flexion contracture deformity by ring fixators and stage 2—total knee arthroplasty (TKA) for arthritis. To the best of our knowledge, no such approach has been reported previously.Conclusions:An Ilizarov ring fixator is a safe technique for gradual correction of a severe flexion deformity. Subsequent TKA can be performed as a standard procedure.

Case:A 4-year-old girl presented with a 5-week-old, neglected fourth metatarsophalangeal (MTP) joint dislocation with malunion of the fourth metatarsal. A previous attempt at closed reduction had failed. The reduction was hindered by dynamic stabilizing of soft tissues around the MTP joint. Open reduction of the fourth MTP joint dislocation and corrective osteotomy of the fourth metatarsal was performed. The patient was pain-free without any cosmetic deformity at the 1-year follow-up.Conclusion:Prompt recognition of a MTP dislocation is vital. The long extensor tendon to the toe can hinder the closed reduction of the MTP dislocation. Osteotomy of the metatarsal malunion is necessary for stable reduction.Level of Evidence:4
