Introduction:
Metatarsophalangeal (MTP) joint dislocations are uncommon due to the joint's inherent stability. Simultaneous dislocations of multiple lesser MTP joints with an associated fracture are extremely rare and typically result from high-energy trauma.
Case Report:
A 36-year-old female sustained dorsolateral dislocation of the 2nd, 3rd, and 4th MTP joints and an intra-articular fracture of the 5th metatarsal base following a tractor run-over injury. Closed reduction under regional anesthesia was successfully performed. The joints were found to be stable post-reduction and immobilized with a below-knee slab. The patient opted against surgical intervention for the 5th metatarsal fracture. At the 3-month follow-up, she showed complete recovery with excellent functional scores.
Conclusion:
Multiple MTP dislocations can be successfully managed with closed reduction and conservative treatment when joint stability is achieved. Patient compliance and close follow-up are critical.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
