OBJECTIVE: To assess the treatment outcomes of patients with four-part fracture of the humeral head after primary and secondary hemiarthroplasty.
PATIENTS: Retrospective long-term analysis of 46 patients from 1996 to 2002 of patients with 47 four-part fractures of humeral head. Patients with malignant disease were excluded.
INTERVENTION: Aequalis (Tornier, Burscheid, Germany).
MAIN OUTCOME MEASUREMENTS: Absolute and relative constant scores at 5-year follow-up examination without age or sex normalization, radiographic parameters of calcification, dislocation of tuberosities, prosthetic loosening, and dislocation of joint.
RESULTS: Eighteen patients treated by primary and 16 patients treated by secondary arthroplasty were assessed clinically and radiologically after a mean follow-up of 64 (60-96) months. The absolute Constant scores at follow-up were 54.9 to 48.5 points, respectively. The relative scores were 61.4% and 57.3%, respectively. Dislocation of tuberosities with severe loss of function was found in five cases treated by primary arthroplasty (13.5%) and in 12 treated by secondary arthroplasty (75.0%).
CONCLUSIONS: The majority of patients in both groups was free of pain or suffered minor pain as determined by the Constant score. Safe fixation of the tuberosities is a prerequisite for functional exercises and is better achieved in primary arthroplasty. A computed tomography scan before operative therapy aids in making the decision between open reduction and internal fixation or hemiarthroplasty.
