Lesser metatarsophalangeal joint plantar plate tears cause instability, often seen in middle-aged individuals or athletes. Understanding injury patterns and surgical options is key for effective treatment.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Foot and Ankle Surgery

Background:

  • Plantar plate degeneration and tears are common causes of lesser metatarsophalangeal joint instability.
  • These injuries often present as attritional patterns in middle-aged patients or chronic injuries in athletes.

Purpose of the Study:

  • To provide an overview of the anatomy, pathophysiology, and classification of lesser metatarsophalangeal joint plantar plate injuries.
  • To discuss surgical indications and open surgical treatment alternatives for metatarsophalangeal joint instability.

Main Methods:

  • Review of anatomical and pathological principles related to plantar plate injuries.
  • Discussion of common injury patterns, grading systems, and surgical decision-making factors.
  • Overview of established open surgical techniques for addressing metatarsophalangeal joint instability.

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

Main Results:

  • Degeneration and tears of the plantar plate lead to capsuloligamentous deficiency and joint instability.
  • Factors such as injury acuity, extent, tissue quality, and patient function guide surgical management.
  • Various open surgical techniques exist for restoring stability to the metatarsophalangeal joints.

Conclusions:

  • Accurate diagnosis and understanding of plantar plate injuries are crucial for preoperative imaging interpretation.
  • Surgical management decisions are influenced by injury characteristics and patient-specific factors.
  • Open surgical interventions offer effective solutions for treating lesser metatarsophalangeal joint instability.
