Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

The Quad Memory Staple (QMS) offers a stable and effective technique for four-corner arthrodesis, improving pain and function with early rehabilitation benefits.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Biomaterials in Medicine

Background:

  • Four-corner arthrodesis is a surgical procedure for wrist instability.
  • Traditional fixation methods have potential complications.
  • The Quad Memory Staple (QMS) is a newer fixation device.

Purpose of the Study:

  • To evaluate the efficacy of the Quad Memory Staple (QMS) in four-corner arthrodesis.
  • To assess range of motion, pain, and complications after QMS fixation.
  • To compare functional outcomes with previous studies.

Main Methods:

  • Retrospective evaluation of nine patients undergoing four-corner arthrodesis with QMS.
  • Assessment of range of motion, grip strength, pain scores, and DASH scores.
  • Mean follow-up of 44 months.

Knotless Independent Double-Row Repair and Biceps Augmentation for Anterosuperior Rotator Cuff Tears

Published on: January 23, 2026

Main Results:

  • Postoperative range of motion was comparable to previous studies.
  • Mean pain scores improved from 41 to 23.
  • Mean DASH scores improved from 24 to 20.
  • No non-union, hematoma, or wound infections were observed.
  • All fusions consolidated successfully.

Conclusions:

  • The QMS provides good stability and allows for early rehabilitation.
  • Its compressive properties and simple technique are advantageous.
  • QMS fixation avoids risks associated with pin fixation methods.
