The podiatrist prescribed a 3 mm rigid, full length orthotic with a neutral heel post and given stretches for the gastrocnemius/soleus muscles.
At that time, the patient began using a new pair of full-length custom orthotics with a 2 mm thickness, 2-degree medial extrinsic heel post and full heel cushion.
prescribes a firmer, more rigid orthotic with a medial heel post to help minimize excessive pronation.
Through clinical experience, it was determined that a 2 mm thick orthotic with a 2-degree extrinsic medial heel post and additional heel cushion was appropriate for her weight level and biomechanical foot dysfunction.
However, approximately 15% are fabricated in steel, usually with timber head and heel posts.
Many composite gates installed in the 1960s and 1970s are nearing the end of their useful life and require refurbishment of the steelwork, in addition to new timber head and heel posts.
The head and heel posts are constructed from wood to allow for adjustment to ensure accurate sealing when the gate is being installed.
The use of sacrificial wooden parts, which are bolted into place, such as the head and heel posts, allow for ease of replacement without closure of the canal and replacement of the whole gate.
The wooden head and heel posts are vulnerable to rot at the water line, with a typical life span of 25 to 30 years before replacement is required.
