Evaluation of forearm abnormalities; clinical and cosmetic results of surgical treatment in patients with multiple hereditaryextoses - multiple osteochondromas.

Abstract

Background: Forearm osteochondromas are found in a vast majority of patients diagnosed with Multiple Hereditary Exostoses - Multiple Osteochondromas (MHE-MO). Common complaints include pain, functional impairment, and cosmetic concerns. So far, there is no consensus regarding optimal treatment or adequate surgical indications as little research has been performed in this population. Objective: The aim of this study is to retrospectively describe and assess the results on range of motion and pain prior to and after surgical treatment of forearm osteochondromas and deformities. Secondary aim is to evaluate patient general and cosmetic satisfaction, and quality of life. Methods: We retrospectively reviewed clinical data of 82 patients surgically treated for forearm osteochondromas due to pain and/or functional impairment. Also, in a cross-sectional part a questionnaire was sent to all 82 patients. The questionnaire focused on patient general and cosmetic satisfaction, pain, and Quality of life Results: Pre-operative range of motion of the forearm and wrist in MHE-MO patients is limited and increases significantly (short- and long-term) after surgery in patients with an indication for surgery due to functional impairment. Pain decreases after surgery, regardless of the indication for surgery. Overall, MHE-MO patients are satisfied, but quality of life is significantly affected. Conclusion: Significant improvements are made in pain complaints and range of motion by excision of osteochondromas or corrective procedures in patients with forearm deformities in MHE-MO. No improvements are seen in cosmetic complaints.
