Abstract

Distension of joint with fluid is often used to facilitate insertion of arthroscope. This may prove difficult at times in the shoulder joint, as unlike the knee, it is deeply situated, making extravasation of fluid outside the capsule, a common occurrence. This is especially true in very tight joints and is often a problem for beginners. We describe here a very effective and simple technique where a needle is used to distend the shoulder before the insertion of the arthroscope.

Summary

Introduction

The shoulder is deeply situated with prominent muscular enclosure. Distension of the joint with saline is often used as a means to facilitate insertion of arthroscope. This may prove difficult at times especially in tight joints and for beginners. The entry point is placed above the midline of the glenoid approximately 1 cm medial and 1 to 2 cm inferior to the posterolateral corner of the acromion This is the so-called 'soft spot' over the posterior aspect of the deltoid, approximating the interval between the infraspinatus and teres minor muscles. The convexity of fluid film at the butt of the needle is lost. This verifies the correct placement of the needle in the joint. As the needle tip enters the shoulder joint, the fluid is sucked in
