Ultrasound is a versatile imaging modality that can be used by upper extremity surgeons for diagnostic purposes and guided injections. Previous studies have demonstrated its ability to diagnose a variety of upper extremity conditions, such as carpal tunnel syndrome5-7,9,10,12,21-23 and rotator cuff injuries.1,8,17,19 A recent prospective study found ultrasound had a better specificity and equal sensitivity compared with nerve conduction studies in a group of patients with clinical evidence of carpal tunnel syndrome.7 A meta-analysis performed by de Jesus et al found that ultrasound and magnetic resonance imaging (MRI) had comparable sensitivity and specificity for diagnosis of full-thickness rotator cuff tears.3 Roy et al suggested that ultrasound was a better option compared with MRI and magnetic resonance arthrography when considering accuracy, cost, and safety.16Although accuracy of therapeutic injections is a multifactorial process that is dependent on physician experience and anatomic region, previous studies have found ultrasound-guided injections to be superior in accuracy compared with palpation-guided injections in the shoulder,2,4,14,15,20 elbow,2 and hand joints.2,11 Ultrasound-guided injections also have the benefit of being a diagnostic modality in addition to therapeutic intervention. Some studies have found that ultrasound-guided injections are associated with better clinical outcomes compared with palpation-guided injections. A randomized clinical trial demonstrated a statistically and clinically significant improvement in shoulder pain and function 6 weeks after injection with ultrasound guidance compared with landmark guidance.18 A retrospective clinical study concluded that ultrasound-guided acromioclavicular joint injections for osteoarthritis resulted in better pain and functional status at 6 months follow-up compared with palpation-guided injections.13The perceptions of ultrasound for diagnosis and treatment among upper extremity surgeons and its barriers for adoption have not been formally surveyed. The purpose of this survey study is to determine the current usage of musculoskeletal ultrasound by upper extremity surgeons and their reasons for using it or not using it. We will also analyze hand surgeon responses across demographic factors to assess whether or not these factors may influence ultrasound usage. The goal of the study is to provide a cross sectional overview of the current use and perceptions of ultrasound among upper extremity surgeons.
