[Old Monteggia lesions in children. Apropos of 14 cases].

Fourteen patients between the ages of 3.5 years and 11 years, with an old Monteggia lesion were managed in the Orthopaedics department between 1968 and 1997. Dislocation of the radial head was not diagnosed at the time of the initial trauma in 9 out of 14 cases and the diagnosis was made an average of 14 months after the trauma (range: 5 weeks to 84 months). Twelve of the 14 patients underwent surgical reduction of chronic dislocation of the radial head, mostly associated with proximal ulnar osteotomy and/or a procedure on the extensor retinaculum. The mean follow-up is 4 years 9 months. There were 66% excellent and good results, 25% of moderate results and 9% of poor results. Due to the difficulty of surgery of neglected lesions, the authors report their experience and emphasize the importance of the initial diagnosis.
