The following are the most important diseases or complications that may be contributed to by impingement syndrome of the shoulder:
Musculoskeletal system and connective tissue (M00-M99).
- Chronic restriction of movement
- Chronic shoulder pain
- Frozen Shoulder (Periarthritis humeroscapularis) – painful frozen shoulder with increasing pain in the shoulder area, at rest and in motion, occurring with certain movements and sometimes radiating to the whole arm
- Tendon rupture (tendon rupture)
- Cervicobrachial syndrome (synonym: shoulder-arm syndrome) – pain in the neck, shoulder girdle, and upper extremities. The cause is often the compression or irritation of spinal nerves (spinal cord nerves) of the cervical spine; most common causes are myofascial complaints (pain in the musculoskeletal system, which do not originate from joints, periosteum, muscle diseases or other neurological diseases), for example, due to myogelosis (muscle hardening) or muscle imbalance of the cervical spine.
Further
- Increasing lack of strength for abduction (lateral travel/spreading) and rotation (twisting) of the arm
