Soft-Tissue Expansion Before Local Bone Reconstruction Using a New Technique for Measuring Soft Tissue Profile Stability

Soft tissue artefact is the dominant source of error in human movement analysis whenever this is carried out using systems based on skin-mounted markers. At the upper-arm, the most corrupted measure is the humerus internal-external rotation: the aim of this work is to propose a new technique for compensating the artefact affecting this measure. The technique is based on the definition of a humerus bone-embedded frame (H2) almost "artefact free" but influenced by the elbow orientation in the measurement of the humeral axial rotation, and on an algorithm designed to solve this kinematic coupling. The algorithm was tested in vitro correcting H2 distortions during different tasks imposed to a mechanical model of the upper-limb; in the most general case of a motion involving all the degrees of freedom of shoulder and elbow, the application of the algorithm reduced the root mean squared error between the known and the measured axial rotation from 8.60° to just 0.12°. By means of the algorithm, therefore, H2 becomes a reliable humerus reference system and its future application for in vivo artefact compensation appears promising.

Clinical Records

ABSTRACT Introduction Ankle sprains are among the most common of bone and joint injuries. Historically, distal tibiofibular syndesmotic injuries have been treated using syndesmotic metal screws to prevent diastasis. However, the use of screws meant that physiological micro-movement between the tibia and fibula was lost which often results in loosening and breaking of the screws. Tightrope fixation was a new technique that has been developed to overcome these complications and allowed some degree of flexibility similar to that offered by natural ligaments. The aim of our study was to evaluate such injuries. Materials and methods We conducted a retrospective study reviewing all clinical records of cases of patients with injuries of the distal tibofibular syndesmosis treated with the ankle tightrope (Arthrex Inc) in our institution between January 2008 and January 2011. Results A total of 42 patients were reviewed. We encountered five cases with complications (12%). Of those: three required removals due to prominent knot, one soft-tissue irritation and one with uncomplicated wound infection. Conclusion Our study, one of the largest so far evaluating complications of tightrope fixation, demonstrates that one in eight patients treated with tightrope will experience complication.
