Question
The patient reported intermittent pain in the left hip and the back of the thigh, with numbness in the left leg after sitting for a long time on a hard chair. There is an abnormal bulge in the waist. Diagnosed by a doctor in Tianjin as a sacroiliac joint subluxation, the symptoms disappeared after the first session of orthopedic treatment, but they relapse (reappeared) two months later. During a subsequent visit, since the original doctor was unavailable, another doctor conducted the treatment. This doctor only adjusted the sacroiliac joint, without addressing the lumbar spine issues. The two doctors’ orthopedic techniques were different, and after treatment, the patient would hear a cracking sound in their back while lying flat. The patient questioned whether the second doctor’s treatment could cause harm and asked whether their condition was a sacroiliac joint subluxation or pelvic rotation, as a deputy director at the Air Force General Hospital had diagnosed it as pelvic rotation. Are these two conditions the same?
