Operative Management: Plantar Plate

Area of Science:

• Orthopedic Surgery
• Podiatry
• Biomechanics

Background:

• The plantar plate is crucial for lesser metatarsophalangeal joint (MPJ) stability.
• Its attenuation can lead to sagittal and transverse plane deformities, such as crossover toe.
• Predislocation syndrome describes early inflammatory stages of plantar plate issues.

Purpose of the Study:

• To review the role of the plantar plate in MPJ stability.
• To discuss the progression from plantar plate insufficiency to crossover toe deformity.
• To highlight the concept of predislocation syndrome.

Main Methods:

• Literature review of biomechanical and clinical studies.
• Analysis of descriptive terminology for MPJ deformities.
• Synthesis of information on plantar plate pathology.

Main Results:

• Plantar plate insufficiency is a primary cause of MPJ instability.
• Deformity progression includes sagittal plane issues followed by transverse plane crossover toe.
• Predislocation syndrome represents an inflammatory precursor to MPJ subluxation.

Conclusions:

• Maintaining plantar plate integrity is essential for MPJ stability.
• Understanding the progression from predislocation syndrome to crossover toe is clinically important.
• Early diagnosis and management of plantar plate pathology can prevent severe deformities.
