Stretch Better Than Stiff: Foot & Ankle
by Dr. John Thomson
Cells are capable of both biochemical and bio-physical signal recognition. This means cells recognize and adapt to forces of compression, shape, and stretch. Mechanobiology is the study of external physical factors and their role in cellular function. First focus: soft tissue.
Move It or Lose It
Tendons require motion after repair. Balance is key. Excessive motion will cause re-rupture or impaired healing of soft tissue. Prolonged immobility will cause adhesions and muscle wasting. Cellular catabolic state results from either extreme. Motion is a necessity, but in a controlled manner.
Orthopedic Devices With Mechanobiology as a Feature
Controlled loading has shown to enhance healing following surgical repair. The solution lies in a stable and reliable construct that will enable early range of motion, and function in loading sharing. Native tissue must be protected, but also continue to feel physical force. Loading sharing and early stability is mechanobiology in action.
