[The late results after mobilizing bone resections in posttraumatic rigidity of the elbow]. / Rezultate la distanta dupa rezectiile osoase mobilizatoare în redorile posttraumatice ale cotului.

Two categories of posttraumatic rigidities are distinguished: partial and total. The severity of partial rigidities depends on the residual flexion-extension amplitude arch and they are divided accordingly into functional rigidities, with a residual amplitude arch of 60-100 degrees, and non-functional ones, with residual flexion amplitude arches of 0-80 degrees or over 100 degrees. The severity of total rigidities depends mainly on the preservation or loss of the pronation-supination movement. To the department where the authors are working were admitted during 16 years (1970-1986), 54 cases of posttraumatic rigidities of the elbow, on which 63 operations were performed. The surgical indications were established according to the anatomopathological type of lesions, to the time elapsed from the accident, to the age and occupation of the patient and to the residual amplitude arches. The late results were checked up after 1-10 years, on the average after 3-4 years, by comparison of pre- and postoperative Rocher indices. The flexion-extension movements benefitted postoperatively by 70% in total rigidities and by 45% in the partial ones and the pronation-supination movements, by 40%. The results regarding the change of the biomechanical functionality conditions following the mobilizing bone resections are shown in comparison with those obtained by arthrosis and total elbow prostheses.

[Long-term results of mobilization by bone resection in patients with post-traumatic total stiffness and ankylosis of the elbow. Study and results of 39 operations]. / Résultats éloignés des résections osseuses mobilisatrices des raideurs totales et ankyloses post-traumatiques du coude. Etude et résultats de 39 opérations.

Thirty patients with post-traumatic stiffness and ankylosis of the elbow were treated operatively at the Colentina Clinical Hospital, from 1970-1986. They were treated by 39 surgical mobilisation using Ollier technique. In eleven patients with a persisting functional amplitude of the prono-supination, the resections have been effected on the distal end of the humerus and on the olecranon, and in nineteen with a limited prono-supination too, it was added a resection of the radial head. The mobilisations were realised without interposition. At follow-up the patients were evaluated after 1 to 8 years, using the pre- and post- operative Rocher's indices and the Kerboull's classification. The flexion-extension was improved by 55 per cent, the pronation by 55.3 per cent and the supination also with 55.3 per cent. The results plead for the maintaining of this type of surgical treatment for the treatment of post-traumatic stiffnesses and ankyloses of the elbow, though there are not complete satisfactory, especially for the joint stability.
