Injuries to the human back have long perplexed the legal world. This is especially true of the soft tissue area of the back, where objective medical tests give way to the vagueness of a "sprained" muscle, and the court finds itself torn between the desire to adequately compensate an injured plaintiff and the caution that must prevail where objective tests are inadequate. Generally speaking, we will be concerned with that portion of the back that is not skeletal in nature,and though the interaction of the spine with the muscular structure permits little latitude in separating them, we will do so for the purpose of limiting the area of discussion.
