研究概览
简要总结
Subacromial shoulder injections can be approached from the front or side of the shoulder. The investigators are comparing both methods, to find which one has better spread in the subacromial space.
详细描述
Both lateral and posterio-lateral methods of subacromial injections are widely used for diagnostic and therapeutic purposes. It is not known which method allows the most accurate access into the subacromial space and is more effective.
The investigators have been using a novel approach from the anterior aspect of the shoulder for years with good clinical effect and propose comparing this approach to the described approach. This study will indicate which method is best and will be of practical clinical importance. The investigators feel the technique is easier to perform than other described methods and could be taught to clinicians throughout the country and adopted as the standard approach.

结局指标
主要结局
The spread of dye in subacromial space
时间窗: With in One hour
The participants will go for an X ray following injection which contains a radio-opaque dye to demonstrate the spread of injected material (Local anaesthetic, depomedrone and Niopam dye) in the subacromial space. A blinded radiologist will read the radiographs and scale the distribution of dye from 1 to 4 depending on the location of radiopaque dye.
次要结局
- Pain control after subacromial injection(With in One hour)
