Non-Operative Management of Symptomatic Hallux Limitus: A Novel Approach of Foot Core Stabilization and Extracorporeal Shockwave Therapy.

BACKGROUND

This video presents assessment and management of hallux limitus using intrinsic foot strengthening and joint mobilization techniques with combination of extracorporeal shockwave therapy (ESWT).

INDICATIONS

Clinical history includes pain with walking, running, jumping, or loaded plantarflexion localized to the first metatarsophalangeal (MTP) joint. Indications for our treatment approach of hallux limitus include pain localized to the first MTP joint, corresponding lack of active range of motion/passive range of motion, and reduced foot/ankle strength often with joint space narrowing on imaging.

TECHNIQUE DESCRIPTION

Our program uses the principle of foot core exercises that enhance intrinsic muscles of the foot to assist in medial longitudinal arch stabilization and hallux strengthening. Progression of these exercises can be done in weight-bearing and impact activities specific to patient goals. In addition to these foot intrinsic exercises, calf raises should be incorporated to strengthen the gastroc-soleus complex to both improve plantar foot strength and facilitate extension of the first MTP joint. Manual therapy techniques reduce the rigidity of the first MTP joint and restore appropriate medial-lateral and plantar-dorsal balance. With severe limitations in mobility or pain limitations, ESWT can be incorporated to treat the joint and surrounding soft tissue restrictions.

RESULTS

Increased first MTP extension is observed. Reduced symptoms of first MTP joint pain with activity allow patients to return to walking and other physical activities with improved comfort. Complications are rare. Pain over the first MTP joint is expected during ESWT. Rarely, irritation of the plantar components of the first MTP joint, including the tibial and fibular sesamoid bones, may occur.

DISCUSSION/CONCLUSION: Non-surgical management of hallux limitus may improve using the described technique of intrinsic foot strengthening with focus on stabilization of the medial longitudinal arch and strategies of improved mobility of the first MTP joint. Adding ESWT may address joint limitations and facilitate gains in exercise and mobility.
