Pain and swelling of the 1st metatarsophalangeal joint

Introduction Pain and swelling of the first metatarsophalangeal joint is one of the clinical diagnoses of stiffness. Stiffness is extremely common, often due to the variation of the position of the first metatarsal, due to excessive internal rotation (pre-spin), toe outward deviation ( valgus), first humeral dorsiflexion (high tibia), or first tibia length increase Or caused by inward bias, and occasional trauma is also a cause.

Cause

Osteoarthritis of the metatarsophalangeal joint is extremely common, often due to variation in the position of the metatarsal, due to excessive internal rotation (pre-spin), toe outward deviation, dorsiflexion of the tibia (high tibia), or increased length of the third metatarsal or Inward bias is also a cause of occasional trauma.

According to the enlargement of the first metatarsophalangeal joint, the movement is limited, the joint capsule has tenderness (especially the lateral side), and the increase of the dorsiflexion of the distal phalanx can be confirmed. X-ray examination of the lateral diseased dorsal hernia showed lateral spurs, and lateral X-ray examination showed exogenous osteophytes protruding from the humeral head. The medical history should include information about the onset of acute gout arthritis, as chronic conditions can cause pain and swelling in the first metatarsophalangeal joint.

Differential diagnosis

Need to be differentiated from gout arthritis, the toe swelling is not painful, it is paroxysmal pain. X-ray manifestations of wind arthritis: soft tissue swelling shadows near the joints in the acute phase, worm-like or perforation-like defects appear at the edge of the joints at the later stage, and the surrounding bone density is increased. Finally, typical arthritis images are present, and bone destruction can cause deformities. Strong.
