Type 3 synostoses are further divided into three different subgroups: type 3A, which affects the proximal third of the forearm without involving the articular surface and is treated as type 2; type 3B, where only the radioulnar joint involved is treated with the excision of the radial head; type 3C, where the radiohumeral
joint is involved and, consequently, the treatment is an arthroplasty [4, 5].
The relationship of the radiohumeral
, radioulnar, ulnohumeral radiocarpal, distal radioulnar joint and the interosseous space must be perfect, otherwise some functional impairment will result.
The elbow joint is opened anteriorly, and the capsule released circumferentially; the humeroulnar and radiohumeral
joints are then disarticulated.
The combination of low power laser therapy and local corticosteroid infiltration in the treatment of radiohumeral
The differential diagnosis in lateral elbow pain includes lateral epicondylitis, radial tunnel syndrome, occult fracture, lateral synovial plica, injury to the lateral collateral ligament, and radiohumeral
joint disease (synovitis, osteoarthritis).
