Extracompartmental Two-Injection Technique for Treating De Quervain Tenosynovitis

Area of Science:

• Orthopedics
• Hand Surgery
• Musculoskeletal Disorders

Background:

• De Quervain tenosynovitis (DQT) is a common condition affecting the tendons of the thumb.
• Traditional treatments, including intracompartmental steroid injections, carry risks and potential complications.

Purpose of the Study:

• To evaluate the efficacy of a novel extracompartmental two-injection technique for treating De Quervain tenosynovitis.
• To compare the outcomes of this new technique with baseline measurements and reported results of other injection methods.

Main Methods:

• A prospective study involving fifteen patients diagnosed with DQT.
• Patients underwent a novel extracompartmental two-injection technique.
• Pain (Visual Analog Scale), grip strength, and physical examination findings were assessed before and four weeks after treatment.

Main Results:

• 100% of patients showed symptom improvement and absent physical exam findings.
• 73% of patients achieved complete symptom resolution.
• 93% of patients experienced improved grip strength post-treatment.
• The technique demonstrated significant improvement in pain and grip strength compared to baseline.

Conclusions:

• The extracompartmental two-injection technique is effective for De Quervain tenosynovitis.
• This method offers comparable short-term outcomes to other techniques while potentially reducing pain and risks.
• The reproducible technique provides a valuable option for clinicians and patients managing DQT.
