Musculoskeletal system and connective tissue (M00-M99).
- Osteoarthritis of the joint
- Bursitis (bursitis)/bursitis
- Chondrocalcinosis (synonym: pseudogout); gout-like disease of the joints caused by deposition of calcium pyrophosphate in the cartilage and other tissues; leads, among other things, to joint degeneration (often of the knee joint); symptomatology resembles an acute attack of gout.
- Gout
- Infectious arthritis (inflammation of the joints)
- Capsular ligament instabilities
- Bone marrow edema/bone marrow swelling (BMO)/bone marrow edema syndrome (BMOS) – term from magnetic resonance imaging (MRI). = edema-equivalent signal changes i.e. increased signal intensity (light) in T2-weighted sequences and decreased signal intensity (dark) in T1-weighted sequences in cancellous bone structures; acute pain and functional limitation of the affected joint; predilection sites (body regions where the disease occurs preferentially): Hip, knee, and upper ankle joints, the talus (ankle bone), and the os naviculare (navicular bone); DD osteonecrosis (“bone death”; ON), which, in contrast to CMOE, progresses rapidly; course is self-limiting (“ending without external influences”; 6-18 months); conservative therapy: Partial weight-bearing on the affected side with a pair of forearm crutches, analgesics (painkillers)/antiphlogistics (anti-inflammatory drugs), and physical therapy; if necessary as an off-label use (prescription of a finished drug outside the use approved by the drug authorities) Iloprost (rheologic) or bisphosphonates; if necessary, surgical therapy: drilling the bone (so-called “core decompression”) – patients with persistent joint pain that can not be explained by an accident or osteoarthritis or unclear joint pain.
- Cartilage damage (chondromalacia radiohumeral or radial head).
- Osteonecrosis (bone infarction; tissue death of the bone).
- Synovitic change/arthritides (e.g., rheumatoid arthritis).
- Soft tissue impingement (painful soft tissue impingement).
- Cervical syndrome – pain and/or sensory disturbances resulting from injury or disease of the cervical spine.
Nervous system (G00-G99)
- C6/C/ syndrome – nerve root compression of C6 or C4 nerve root: this involves the dermatome (skin area autonomously supplied by the sensitive fibers of a spinal nerve root/spinal cord root) that mimics the radiations of epicondylopathy (roughly corresponding to the 6th cervical nerve root).
- PIN syndrome (synonyms: radial tunnel syndrome, radial pronator syndrome, or supinator tunnel/supinator ligament syndrome) – compression syndrome of the ramus interosseus posterior of the radial nerve
- PIN syndrome: muscle weakness of the muscles innervated by the PIN associated; overuse (athletes and violinists), external compression (walking stick use); clinical presentation: pain at the dorsoradial portion of the forearm, which is worsened by pro-/supination. Pronation: internal rotation: in this rotation of the forearm over cross the ulna and radius; supination outward rotation: in this rotation, the ulna and radius are parallel to each other after rotation.
- Radial tunnel syndrome: mainly with pain in the course of the radial tunnel.
- Pronator teres syndrome – lesion of the median nerve when passing in the area of the pronator teres muscle on the forearm.
- Radialis compression syndrome
- Thoracic-outlet syndrome (TOS; neurovascular compression syndrome) – upper thoracic aperture constriction syndrome or shoulder girdle compression syndrome.
Neoplasms – tumor diseases (C00-D48).
- Tumor in the area of the joint
Injury, poisoning, and certain other sequelae of external causes (S00-T98).
- Fracture (broken bone)
- Traumatic causes
- Injury Late Damage
