The Venous Pump of the First Metatarsophalangeal Joint: Clinical Implications

Abstract

Our described connection between the joint capsule and veins indicates a "toe-ankle pump" with a significant increase of venous blood flow during motion of the MTP joint. Possible clinical applications for an external MTP pump include anti-edema or thromboprophylactic therapy, especially in patients with foot or ankle injuries. A new toe-pump has been designed based on these results.

<p>Comparison of a Novel Muscle Training Device with Conventional Rehabilitation Training in Motor Dysfunction of Lower Limb Patients: A Pilot Study</p>

“…According to previous studies, age is an important risk factor for lower limb DVT in patients with fracture. 23 The blood in the venous sinuses of the leg muscles requires the action of the muscle pump to effectively achieve centripetal return. Venous insufficiency of the lower limbs or partial loss of the function of the venous pump requires effective lower limb exercise to improve venous return.…”

Thrombembolic complications after total ankle replacement

“…Weight-bearing is allowed as tolerated with the exception of patients who underwent additional corrective osteotomies. Active and passive mobilization of the first metatarsophalangeal joint may increase venous blood flow of the lower extremity, which results in an antiedema and thromboprophylactic effect [68].…”

Review Article: Venous Thromboembolism after Total Joint Replacement

“…13 The use of the foot pump can decrease the rate of DVT in THR and TKR patients. [44][45][46][47] Active mobilisation exercises of the foot and ankle can increase venous flow, 38,39 but their effectiveness as a prophylactic measure is unknown.…”

“…36 Mechanical prophylaxis includes graduated compression stocking, intermittent calf compression, foot pump, and early mobilisation. These act by increasing the velocity of venous blood flow and preventing stasis, 38,39 as well as decreasing the coagulability of blood by stimulating fibrinolysis. 40 Graduated compression stocking is easy to apply.…”
