In the human foot, the
The plantar plate supports the weight of the body and restricts dorsiflexion, whilst the main
The plantar plate is firm but flexible fibrocartilage with a composition similar to that found in the
Metatarsophalangeal joints
At the metatarsophalangeal joint the plantar plate plays an important role in the foot's weight-bearing function.
The plantar plate is attached to the proximal phalanx, to the major longitudinal bands of the plantar fascia, and to the collateral ligaments. Together with the collateral ligaments, it forms a soft tissue box which is connected to the sides of the metatarsal head. The plate from the substantial distal insertion of the plantar fascia and can withstand tensile loads in line with the fascia itself. The plate can withstand compressive loads from the metatarsal head because of the orientation of the fibers in its fibrocartilage. [3]
The skeleton of the foot rests on a multi-layered ligamentous system of beams and trusses that responds to weight-bearing on irregular surfaces. A transverse system at the MTP joints is formed by the plantar plates and the
