Simple posterior elbow dislocations are often being treated with strict immobilization after reduction. We performed a study in order to investigate if a functional protocol of rehabilitation, allowing early motion, would be more effective.

We prospectively followed twenty five consecutive patients for simple posterior elbow dislocation in a non-randomized study. Patients were divided in two groups. Group A (twelve cases) was treated with immobilization using a cast in 90 degrees of flexion and neutral rotation for three weeks. Group B (thirteen cases) was treated according to a functional rehabilitation program that allowed early controlled mobilization starting on the 2nd post-traumatic day, consisting of immediate flexion from 90° and gradual extension after the 2nd week. Follow-up of the patients was recorded at six weeks and three months. The functional scores used were Mayo Clinic Performance Index, Liverpool Elbow score and Broberg and Morey.

None of the patients had an incident of redislocation. Patients of group B had statistically significant better (p< 0.05) functional scores at six weeks and better no statistically significant in three months: group B/group A: Mayo: 91.6/65.5, Liverpool: 8.8/6.1, Broberg and Morey: 89.1/73.3.

It seems that a functional rehabilitation program gives the same result in terms of stability offering at the same time patients a better range of motion and functional score at least at six weeks and three months.

In Essex-Lopresti injuries, the prevailing concept, according to which the stability of the forearm can be restored after fixation of the fracture or replacement of the radial head by a metallic implant, is disputable. The aim of this study is to evaluate the midterm results in 12 patients with an Essex-Lopresti injury who were treated operatively.

We studied 12 patients, with comminuted fracture of the radial head, either isolated (4 patients) or with injury of the ipsilateral (4 patients) or the contralateral (4 patients) arm. Initially, 10 patients were treated with excision of the radial head whereas 2 underwent internal fixation of the radial head and pinning of the DRUJ. Eventually, everyone developed a subluxation of DRUJ and had to be treated for an established Essex-Lopresti injury, 1–7 months after the initial injury. Six patients were treated with equalization of the radioulnar length (ulnar shortening osteotomy with or without a distractor-external fixator) and restoration of the TFC, while six patients underwent replacement of the radial head with a titanium implant, equalization of the radioulnar length and restoration of the TFC.

The results were evaluated after a mean follow-up of 4 years (1–12 years), based on radiological and clinical criteria. The six patients in whom the titanium radial head implant was used presented with good results, even though two of them reported forearm pain during activity. On the contrary, in the rest of the patients the radioulnar incongruity reappeared in varying degrees. However the poor radiological result was not consistent to the clinical one.

We conclude that in cases of complete rupture of the interosseous membrane, internal fixation or replacement of the radial head with a metallic implant will not probably provide us with a good long-term functional result.
