CASE: The patient sustained a pathologic fracture through chronic osteomyelitis of the tibia. Treatment involved resection of bone and soft tissue, leaving a 15-cm diaphyseal tibial defect. We designed a construct to allow for trifocal bone transport using a magnetic intramedullary lengthening nail connected to cables. This technique uses cables secured to the proximal tibia, the nail, and the transport segments. CONCLUSION: This case details the successful use of trifocal cable-assisted bone transport through a magnetic lengthening intramedullary nail...

INTRODUCTION: Segmental tibia defects remain challenging for orthopedic surgeons to treat. The aim of this study was to demonstrate bone-related and functional outcomes after treatment of complex tibial bone defects using Ilizarov bone transport with a modified intramedullary cable transportation system (CTS). PATIENTS AND METHODS: We conducted a single-center, retrospective study including all 42 patients treated for tibial bone loss via Ilizarov bone transport with CTS between 2005 and 2018...

BACKGROUND: Massive bone defects (>8 cm) will not unite without an additional intervention. They require a predictable, durable, and efficient method to regrow bone. The Ilizarov method of tension stress, or distraction osteogenesis, first involves a low-energy osteotomy1-5 . The bone segments are then pulled apart, most often using an external device at a specific rate and rhythm (distraction phase), after which the newly formed bone (the regenerate) requires time for consolidation...

Ring fixation is a powerful tool in the treatment of bone defects. The ability to create high-quality, biologically normal new bone of even massive proportions using distraction osteogenesis is a major reason for its success. In addition, ring fixation provides the ability to limit the risk of deep infection, improves flexibility in limb length control and alignment, and increases soft tissue coverage options. The drawbacks of ring fixation include long frame times, pin problems, risk of joint contractures, and difficult usage in areas with a large soft tissue envelope such as the thigh...

REVIEW
Stephen Matthew Quinnan, Charles Lawrie
Distraction osteogenesis has proven effective in the management of tibial bone loss from severe trauma and infection. Unfortunately, pain and scarring from wires and half pins dragging through the skin and the required prolonged time in the external fixator make treatment difficult. Cable bone transport has been shown to improve cosmesis and decrease pain during transport. However, the published methods have limitations in that they have poor control of transport segment alignment, do not allow for lengthening of the limb, and do not permit weight bearing during the treatment process...

UNLABELLED: Although the rate of surgical intervention for pediatric cervical spine injuries has risen, none of these instrumentation techniques has been reported in children less than 1 year of age. Additional consideration with placement of wires or cables is not safe because of the presence of cartilaginous bone and poor bone strength. The authors report a technique of internal fixation without fusion using nonabsorbable synthetic suture in an infant with unstable cervical injury. METHODS: A 5-month-old girl was transported to emergency department and computed tomography showed severe distraction injury at the C6-7 level with total disruption of the facet joints bilaterally...

Distraction osteogenesis after post-traumatic segmental bone loss of the tibia is a complex and time-consuming procedure that is often complicated due to prolonged consolidation or complete insufficiency of the regenerate. The aim of this feasibility study was to investigate the potential of bone marrow aspiration concentrate (BMAC) for percutaneous regenerate augmentation to accelerate bony consolidation of the regenerate. Eight patients (age 22-64) with an average posttraumatic bone defect of 82.4 mm and concomitant risk factors (nicotine abuse, soft-tissue defects, obesity and/or circulatory disorders) were treated with a modified Ilizarov external frame using an intramedullary cable transportation system...

BACKGROUND: Abnormal mechanical loading occurs in scoliosis as compared to normal spines. Intervertebral disc degeneration has been correlated with alteration of bone density in adjacent vertebral bodies. How vertebral end plate remodels in scoliosis and the consequences on disc homeostasis are not well understood. Permeability is a relevant physical measure to quantify mass transport in porous media. We hypothesized that effective permeability of the vertebral end plate was modified by growth modulation in a scoliosis animal model...

Traditional segment transport methods pose major soft tissue and bone problems related to the pin or K wire that fixes the transported bone segment through the soft tissue, especially excursion of the K wire. We designed the cable bone transport technique to prevent these problems and to increase patient comfort. Thirteen patients with bone defects (11 in the tibia and 2 in the femur) were treated successfully with the new method. Because the transported segment is not fixed externally in the cable bone transport method, docking site troubles, such as soft tissue invagination and malalignment, and skin problems due to excursion of the K wire are prevented, which in turn reduces other difficulties that might arise from alternative procedures...

Bone transport applying the principle of distraction osteogenesis makes it possible to reconstruct long bone defects caused by trauma or resection of bone tumors. The method employing a central cable, developed in Munich, is especially suitable for such applications. The main bone fragments are stabilized by an external fixateur, and bone transport is effected with a single central cable fixed to the tip of the segment, and driven by an external, programmable motor. In 15 patients the tractive forces during the entire bone transport were measured with a strain gauge incorporated within the cable...

Distraction osteogenesis involving bone transport enables the reconstruction of large bone defects. The main bone fragments are usually stablilised externally, an intermediate bone segment is separated and moved through the defect at a rate of about 1 mm/day. New high-quality bone is built up in the constantly enlarging osteotomy gap. A major problem associated with the method is the fact that the fixation pins are also moved over the same distance, and cut through the soft tissue, often resulting in painful pin tract infections and ugly scars...

PURPOSE: To evaluate the load to failure and the mode of failure of a novel suture anchor construct that does not require knots (the "twist-lock" construct) and to compare it with a standard suture anchor construct (Corkscrew; Arthrex, Naples, FL). TYPE OF STUDY: Biomechanical single-pull load-to-failure study comparing the twist-lock construct to the Corkscrew suture anchor construct. METHODS: The twist-lock construct is a suture anchor system that does not use knots, instead using 3 consecutive twists between suture limbs to enhance internal interference between the suture limbs...

The transfixing wires used in the limb-lengthening and bone-transport procedures described by Ilizarov are the primary source of complications, including infection, restricted joint motion, and pain. In an attempt to eliminate the need for external fixation, a traction cable device was devised to perform a 3-cm bone transport in the canine femur using an interlocking intramedullary rod for fixation. Twelve dogs were divided into 2 groups. Transport began 7 days after osteotomy and continued at either 1 mm per day (n = 6) or 2 mm per day (n = 6)...

The popularity of the motorcycle, specifically trail bike riding, in the past several years has produced an increasing incidence of severe "clothesline" injuries to the larynx and trachea. Even at moderately high speed the impact of a horizontal cable with the neck of the rider causes a sudden hyperextension of the neck, and an avulsion of the larynx from the trachea, separating at the relatively rigid fibrous connective tissue between the cricoid cartilage and the first tracheal ring. Interruption of the strap muscles, the recurrent laryngeal nerves, laceration of the esophagus, and compression fracture of the cervical vertebral bodies can occur...
