Cardiovascular (I00-I99).
- Peripheral arterial occlusive disease (pAVD) – progressive narrowing or occlusion of the arteries supplying the arms/ (more commonly) legs, usually due to atherosclerosis (arteriosclerosis, hardening of the arteries).
Mouth, esophagus (esophagus), stomach and intestines (K00-K67; K90-K93).
- Inguinal hernia (inguinal hernia/inguinal hernia).
Musculoskeletal system and connective tissue (M00-M99).
- Bacterial arthritis (infection of the joints).
- Bursitis (inflammation of the bursa)
- Coxitis (inflammation of the hip joint)
- Femoro-acetabular impingement (tightness syndrome between the femoral head and acetabulum).
- Femoral head necrosis – tissue death due to lack of blood supply to the femoral head (no acetabular involvement).
- Insertion tendinopathy – pain conditions arising from irritation at the junction between tendons and bone, i.e. in the area of insertion.
- Intraosseous ganglion – ganglion located in the bone.
- Bekhterev’s disease (ankylosing spondylitis; Latinized Greek: spondylitis “inflammation of the vertebrae” and ankylosans “stiffening”) – chronic inflammatory rheumatic disease of the spine that can lead to joint stiffness (ankylosis) of the affected joints.
- Osteoporosis (bone loss)
- Osteoporotic fracture – bone fracture caused by osteoporosis.
- Projected pain from the knee joint in gonarthrosis (knee osteoarthritis).
- Rheumatoid arthritis – inflammatory multisystem disease, which usually manifests itself in the form of synovitis (inflammation of the synovial membrane).
- Sacroiliitis – inflammation of the joint between the sacrum and the ilium.
- Spinal stenosis – narrowing of the spinal canal.
- Snapping hip syndrome (coxa saltans) – harmless, sometimes audible tendon snapping during flexion and extension of the hip joint; however, snapping hip can also contribute to bursitis (bursitis) of the greater trochanter (large rolling mound of the thigh bone), for example, during intense muscle training; this can lead to pain when walking
Neoplasms – tumor diseases (C00-D48).
- Chondromatosis – occurrence of multiple benign tumors in bone.
- Metastases (daughter tumors)
- Tenosynovial giant cell tumor – tumor originating from the synovial membrane.
- Tumors, unspecified
Psyche – nervous system (F00-F99; G00-G99)
- Piriformis syndrome – compression of the sciatic nerve in the infrapiriform foramen in various local processes; severe pain in the gluteal region with radiating back pain.
- Radicular syndromes – pain syndromes caused by the nerve roots.
