Plantar Plate Injury: Lesser MTP Instability and Predislocation Syndrome

Medically reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatric Surgeon — Balance Foot & Ankle, Howell & Bloomfield Hills, MI. Last updated April 2026.

Plantar plate tears — disruption of the fibrocartilaginous plantar plate at the lesser metatarsophalangeal (MTP) joint — are a frequently underdiagnosed cause of forefoot pain, progressive lesser toe deformity, and the crossover toe deformity. The plantar plate is the primary stabilizer of the MTP joint against dorsal subluxation; when it fails, the toe progressively migrates dorsally and medially — producing the crossover second toe deformity that is essentially pathognomonic for second MTP plantar plate disruption.

Anatomy and Clinical Presentation

The plantar plate — a dense fibrocartilaginous structure attached to the plantar base of the proximal phalanx and the deep transverse metatarsal ligament — resists MTP joint hyperextension and bears metatarsal head plantar pressure during push-off. Predislocation syndrome (the clinical precursor to frank dislocation): plantar forefoot pain localized to the second MTP joint, pain with MTP dorsiflexion, swelling of the second MTP joint (a plantar effusion visible on physical examination), and positive drawer test (Lachman test of the MTP joint — longitudinal traction on the proximal phalanx producing dorsal subluxation indicates plantar plate incompetence). MRI of the forefoot confirms plantar plate integrity and grades the tear — grade 0 (attenuation without tear) through grade 3 (complete disruption with dislocation).

Treatment

Conservative management for grade 0–1 tears: metatarsal pad placed proximal to the metatarsal head to offload the MTP joint, dorsal MTP taping (figure-8 tape holding the toe in slight plantarflexion), and modification of footwear with a wide toe box and low heel. Surgical management for grade 2–3 tears and failed conservative management: direct plantar plate repair through a plantar approach, frequently combined with Weil metatarsal shortening osteotomy to reduce tension on the repair site. Dr. Biernacki at Balance Foot & Ankle evaluates forefoot pain with clinical MTP drawer testing and MRI when plantar plate pathology is suspected.

When to See a Podiatrist

Many foot conditions can be managed conservatively at home, but some require professional evaluation. See a podiatrist promptly if you experience:

• Pain that persists for more than 2 weeks despite rest
• Swelling, redness, or warmth that isn’t improving
• Numbness, tingling, or burning in the feet
• A wound or sore that is not healing within 2 weeks
• Any foot concern if you have diabetes or poor circulation
• Nail changes that suggest fungal infection or other problems

At Balance Foot & Ankle, our three board-certified podiatrists — Dr. Tom Biernacki, Dr. Carl Jay, and Dr. Daria Gutkin — provide comprehensive foot and ankle care at our Howell and Bloomfield Township offices. Most insurance plans are accepted.

Most Common Mistake We See

The most common mistake we see is: Waiting too long before seeking care. Fix: any foot pain lasting more than 4 weeks, or any sudden severe symptom, deserves a professional evaluation rather than more rest.
