What Is Biomechanics?

“Biomechanics” is the science of functional Orthopaedics with its own precise three dimensional language. Examination of a resting or static body may produce little evidence of deformity or irregularity when functional disorders are the cause of discomfort or pain. Similar to engineering structures, if skeletal stability is flawed for whatever reason then it is unlikely that the structure will be capable of supporting itself as intended. The human body is no different and many orthopaedic problems arise as a direct result of our need to stand and walk in an upright manner. Biomechanics is the science used to identify and compensate for these irregularities.

The reporting output must  be readily understood and of value to practitioners both biomechanically and surgically. Historically within the UK, only a handful of experienced practitioners have had the necessary skills to provide consistently accurate results and even they will frequently prescribe differing posting values for a given patient. The Orthoscanner System, by comparison, captures dynamically on all planes at high speed, thus offering the laboratory the opportunity to analyse at any given moment during gait. The results are accurate and reproducible. Analysed frames can also be forwarded to the practitioner along with results and reports thereby providing information in a simple and understandable format. Pre and post surgical appraisals and medico legal evaluations are also common practice.

Advanced image analysis software is employed in the laboratory to extract all necessary information for examination purposes, the results of which are made available to the prescribing practitioner. A typical analysis would show 250 pieces of topical information with an alert system for highlighting major deviation problems. All anatomical indicator positions can be mathematically calculated; human error is eradicated by utilising software routines.  

 

In summary, the system allows our laboratory analysts to assess the prescribing practitioner’s patient in the laboratory.  The analytical data is passed to the practitioner who makes the final decision on treatment based on the recommendations in the laboratory report.  If a prescription for orthoses is agreed the laboratory applies the compensations to the 3-D model of the patient’s foot on the laboratory computer and then transmit the instructions to the milling companies. The orthoses are either formed or milled out of a block and returned to laboratory for quality control examination prior to shipment to the practitioner for fitting on the patient.

 The laboratory will, as standard, provide results of the analysis performed and a report highlighting problems we wish to bring to the practitioner’s attention. Our analysis procedures quantify non-ambulatory joint excursions within the segmented foot and leg as well as the dynamic angular demand. We  also offer an opinion on the treatment of the biomechanical disorder. The laboratory provides accurate biomechanical evaluations on different optional levels, depending on the information required and patient needs. Pre and post surgical evaluations or Medico legal appraisals are also available on demand.  Reports are delivered electronically via this website.
