Prevalence of Septated First Dorsal Compartment Among Iranian Patients with De Quervain Tenosynovitis

Abstract

The presence of a septum in the first extensor compartment is associated with the failure of nonsurgical treatments and a higher number of extensor pollicis brevis (EPB) and abductor pollicis longus (APL) tendons with the likelihood of development of the de Quervain disease. →What this article adds:Although the condition is well described in other populations, to the best of our knowledge, there have been no prior studies on the Iranian population, making this case series the first study to report the condition in the Iranian population. In this study, most patients had 2 APL tendons and 1 EPB tendon, and most affected wrists had a septum in the first extensor compartment.

Relationship to the superficial radial nerve and anatomic variations of the first extensor compartment in Thai population: a basis for successful de Quervain tenosynovitis treatment

“…Another injection technique with a high efficacy rate (89%) for cases of septa with two-point injections is one and another over the EPB and APL tendons [ 32 ]. In addition, several studies focused on septal prevalence inside the 1st EC (we listed some of them in Table 5 ) [ 33 - 45 ]. Kulthanan and Chareonwat [ 33 ] investigated septal prevalence in patients with de Quervain compared to cadavers of assumably physiological states.…”
