AbstractTreatment of comminuted intra-articular fractures of the distal humerus in elderly patients remains a challenge in trauma surgery. These fractures are rare, but their frequency increases. Our multicenter studies collected 238 cases of comminuted intra-articular fractures of the distal humerus in patients older than 65: two hundred and five cases for the retrospective study, 33 for the prospective study with a minimum follow-up of six months. The following criterias were studied: age, sex, state of health (with ASA score), functional scores (with Katz score), osteoporosis by the OST score and dual X-ray absorptiometry. The results were evaluated according to the Mayo Elbow Performance Score (Morrey) and the Quick DASH. X-ray studies were performed in order to assess both results for prosthesis and osteosynthesis. The following criteria were studied: bone healing, quality of reduction, signs of arthritis (Broberg-Morrey), prosthetic position, mechanical complications, prosthesis fixation. There were 80% of women in good health according to the ASA score (more than 70% of ASA 1 or 2). Most of them (80%) were self-governing and living at home. Hundred and seventy-two patients had an osteosynthesis and 44 had a prosthetic reconstruction (like Coonrad-Morrey prosthesis). Patients treated with osteosynthesis were younger (mean age was 77) than those treated with prosthetic reconstruction (mean age 81). Mean follow-up was 32 months. Results of osteosynthesis were good and excellent for 77% of the patients. Complications occurred for 20% of patients with a reoperation rate of 13%. Results of prosthetic reconstruction were good and excellent for 83% of the patients with 14% of complications and 6% of reoperation. Prosthetic reconstruction seemed to be better than osteosynthesis according to the Mayo Clinic score (84 points versus 77 points for the retrospective study and 95 points versus 75 points for the prospective study). However, the statistical analysis was not significant. Treatment of these fractures must be discussed according to the physiological status of the patient and the fracture patterns (scan evaluation). In conclusion, osteosynthesis remains the standard treatment when stable fixation is feasible. However, prosthetic reconstruction should be discussed for dependant patients or with comorbidity factors, bad bone quality leading to poor osteosynthesis or complex fracture.
