Medical Bandages To Maintain Limb

During medical bandaging, the limb being bandaged must be held in a functional position or a specific position designated by the doctor. This typically requires relaxed muscles and joints in an extended or slightly flexed position. For example, when bandaging the lower limb, the ankle should be held at a 90-degree angle to prevent foot drop deformity later; when bandaging the upper limb, the fingers should be naturally extended.

If bandaging is forcibly applied while the muscles are contracted or the joints are flexed, the bandage will become excessively tight when the limb returns to its natural position, acting like a tourniquet to block blood flow, leading to ischemia, numbness, or even necrosis in the distal extremities. Therefore, maintaining the correct limb posture is a crucial prerequisite for safe and effective bandaging.
