Should the Joint Capsule of the Painful Stiff Shoulder be Ruptured During Intra-articular Hydraulic Distension?

July 21, 2011 updated by: Seoul National University Hospital

Comparative Study for the Efficacy of Capsule-Preserving Versus Capsule-Rupturing Intra-articular Hydraulic Distension in Patients With Painful Stiff Shoulders

The purpose of the study is to compare the efficacy of intra-articular hydraulic distension (IHD) for the treatment of painful stiff shoulders between capsule-rupturing and capsule-preserving IHDs.

Study Overview

Detailed Description

The Painful stiff shoulder (PSS), or the adhesive capsulitis, involves stiff and contracted joint capsule from fibrosis in the glenohumeral joint. Intra-articular hydraulic distension (IHD) enlarges the stiffened capsule by deforming it with excessive volume and pressure within the joint space. Although IHD is one of the most common treatment options for the PSS, the diversity of the IHD technique spans wide range. Specifically, it is not generally agreed as for which, between capsule-rupturing and capsule-preserving IHDs, is superior for PSS treatment. Capsule-preserving IHD might fail to infuse sufficient amount of fluid to avoid rupture, thus producing less satisfactory outcomes. However, we devised in our previous study a novel technique that enabled a physician to infuse the possible largest volume without rupturing the capsule. By employing the technique, we aim to compare the clinical efficacy of capsule-rupturing versus capsule-preserving IHDs in patients with PSSs.
