“…In a similar study presented by Baumgart et al [16], the force curve progression demonstrated the same pattern of behaviour as in the current authors’ subjects. However, as there are no data available on traction forces for BST in living humans measured in IMS, no exact conclusion of the amount of force generated by the soft tissues contributing to the overall force is possible.…”

Callus distraction using bone segment transport systems is an applied process in the treatment of bone defects. However, complications such as muscle contractures, axial deviation and pin track infections occur in the treatment process using the currently available devices. Since successful treatment is influenced by the applied distraction force, knowledge of the biomechanical properties of the involved soft tissues is essential to improve clinical outcome and treatment strategies. To date, little data on distraction forces and the role of soft-tissue traction forces are available. The aim of this study was to assess traction forces generated by soft tissues during bone segment transport using a novel intramedullary callus distraction system on eight human femora. For traction force measurements, bone segment transport over 60-mm femoral defects was conducted under constant load measurement using 40- and 60-mm bone segments. The required traction forces for 60-mm bone segments were higher than forces for 40-mm bone segments. This study demonstrates that soft tissues are of relevance biomechanically in bone segment transport. The size of the bone segment and the selection of the region for osteotomy are of utmost importance in defining the treatment procedure.

“…The overall force required for BST consists of several different load components [9, 15, 16]. All adherent structures of the transporting bone segment such as tendons, fasciae and muscles generate a force due to the distraction of the soft tissues.…”

“…In the literature, there are several articles that had described a modification of an internal bone transport technique, each having unique advantages and disadvantages 262728. However, all of these above-mentioned techniques had been described for the treatment of defects localized in the long bones of the lower limb, technically challenging to be performed in dimensionally smaller or comparatively weaker bones such as forearm bones.…”

Background: Defects of bone and soft tissue occur frequently after high-energy trauma, infections, and tumor resection. Treatment options are limited and outcomes are controversial in nonunion. Classical reconstruction methods are challenging. We describe a method of internal bone transport for treatment of complicated nonunion of the forearm. This method permits axial and internal bone transport without harming the distorted and complex neurovascular anatomy or soft-tissue envelope. Materials and Methods: Five patients (mean age, 27 years) with defect nonunion (3 ulna, 2 radius) were treated. Mean preoperative defect size was 36 mm, mean shortening was 14 (0–30) mm, and the extent of surgical resection was 24 (20–40) mm. Total bone loss due to defect, resection, or shortening was 74 mm. According to Paley classification, two of the patients had B1, and three had B3 defect nonunion. This study treats defect nonunion of the forearm using an internal bone-transport method. Our method involved cannulated screws, a cerclage wire, and a circular fixator being used in combination. When transportation was completed, internal fixation of the docking site with a plate and screws was done, with bone grafting after fixator removal. Bone healing and functional outcomes were assessed with radiographs and disabilities of the arm, shoulder, and hand (DASH) scores, respectively. Results: Mean followup was 67.6 months. Solid osseous union and functional improvement were achieved in all cases. Mean bone loss was 66 mm, mean fixator time was 131.8 days, the lengthening index was 1.3 days/mm, and the fixator index was 2.1 days/mm. DASH score was 82.2 before treatment and 15.36 after treatment. Conclusions: Using our method, internal bone transport and progressive axial docking of defects can be done with minimal effects on surrounding neurovascular arrangements and soft tissues. Size of fixators can be decreased and formation of painful scar tissue can be avoided.
