BACKGROUND: Posttraumatic arthritis and prolonged recovery are typical after a severely comminuted tibial pilon fracture, and ankle arthrodesis is a common salvage procedure. However, few reports discuss the option of immediate arthrodesis, which may be a potentially viable approach to accelerate overall recovery in patients with severe fracture patterns. QUESTIONS/PURPOSES: (1) How long does it take the fracture to heal and the arthrodesis to fuse when primary ankle arthrodesis is a component of initial fracture management? (2) How do these patients fare clinically in terms of modified American Orthopaedic Foot and Ankle Society (AOFAS) scores and activity levels after this treatment? (3) Does primary ankle arthrodesis heal in an acceptable position when anterior ankle arthrodesis plates are used? METHODS: During a 2-year period, we performed open fracture reduction and internal fixation in 63 patients. Eleven patients (12 ankles) with severely comminuted high-energy tibial pilon fractures were retrospectively reviewed after surgical treatment with primary ankle arthrodesis and fracture reduction. Average patient age was 58 years, and minimum followup was 6 months (average, 14 months; range, 6-22 months). Anatomically designed anterior ankle arthrodesis plates were used in 10 ankles. Ring external fixation was used in nine ankles with concomitant tibia fracture or in instances requiring additional fixation. Clinical evaluation included chart review, interview, the AOFAS ankle-hindfoot score, and radiographic evaluation. RESULTS: All of the ankle arthrodeses healed at an average of 4.4 months (range, 3-5 months). One patient had a nonunion at the metaphyseal fracture, which healed with revision surgery. The average AOFAS ankle-hindfoot score was 83 with 88% having an excellent or good result. Radiographic and clinical analysis confirmed a plantigrade foot without malalignment. No patients required revision surgery for malunion. CONCLUSIONS: Primary ankle arthrodesis combined with fracture reduction for the severely comminuted tibial pilon fracture reliably healed and restored acceptable function in this highly selective patient group. Ring external fixation may be a useful adjunct to internal fixation, and this concept should be further studied. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

OBJECTIVES: Document fixation and healing of distal femur fractures stabilized by plate osteosynthesis using far cortical locking (FCL) screws. DESIGN: Prospective and observational. SETTING: Two level 1 and 1 level 2 trauma centers. PATIENTS: Thirty-two consecutive patients with 33 distal femur fractures (AO/OTA types 33A, 33C). INTERVENTION: Fractures were stabilized by plate osteosynthesis with MotionLoc FCL screws without supplemental bone graft or bone morphogenic proteins. Patients were followed up for a minimum of 1 year with functional and radiographic assessments obtained at postoperative weeks 6, 12, and 24 and computed tomography scans at week 12. If union was not confirmed within 1 year, follow-up was continued until union or revision surgery. MAIN OUTCOME MEASURES: The primary end point was fracture union in the absence of complications and secondary interventions. Fracture healing was defined by resolution of pain at the fracture site and cortical bridging on biplanar radiographs. Complications were defined by fixation failure, loss of reduction, implant breakage, infection, nonunion, and need for revision. RESULTS: Thirty-one fractures were available for follow-up. None of the 125 FCL screws used for diaphyseal fixation broke or lost fixation. One of the 31 fractures displaced into varus (ΔVarus = 5.8 degrees). Thirty of the 31 fractures healed within 15.6 ± 6.2 weeks. At an average follow-up of 17 ± 4 months, there were 2 revisions: one to correct a malrotation at day 5 and one to treat a nonunion at 6 months. CONCLUSIONS: Absence of implant and fixation failure suggests that dynamic plating of distal femur fractures with FCL screws provides safe and effective fixation.

We recommend gradual correction of distal tibia varus as most applicable for patients with severe deformities that would not be adequately corrected with acute methods. Complex deformity, compromised soft tissues, and limb shortening are, in general, better managed with this technique.

The Americans with Disabilities Act (ADA) gives all Americans with disabilities a chance to achieve the same quality of life that individuals without disabilities enjoy. In this case report, we will be discussing the consequences of having inaccessible ramps to persons with disabilities that can result in severe musculoskeletal injuries in a wheelchair user. While going down an inaccessible ramp in the garage of a hospital, a wheelchair tipped over, causing a fracture to the user's right femur. The injured patient was taken to the Emergency Department, where the diagnosis of a fracture of the right femur was made. The fracture then had to be repaired with an intramedullary rod under general anesthesia in the hospital. It was discovered that the ramps in the hospital garage did not comply with the guidelines of the ADA. The wheelchair ramps had a ramp run with a rise > 6 inches (150 mm) and a horizontal projection > 72 inches (1830 mm). This led to the redesign and construction of safe ramps for individuals using wheelchairs as well as for pedestrians using canes, within 1 month after the patient's injury, making it safe for wheelchair users as well as pedestrians using the parking facilities. The ADA specifies guidelines for safe ramps for patients with disabilities. It is important to ensure that hospital ramps comply with these guidelines.

Numerous techniques for ankle arthrodesis have been reported since the original description of compression arthrodesis. From the early 1950s to the mid 1970s, external fixation was the dominant technique utilized. In the late 1970s and 1980s, internal fixation techniques for ankle arthrodesis were developed. In the 1990s, arthroscopic ankle arthrodesis was developed for ankle arthrosis with minimal or no deformity. The open technique is still widely used for ankle arthrosis with major deformity. For complex cases that involve nonunion, extensive bone loss, Charcot arthropathy, or infection, multiplanar external fixation with an Ilizarov device, with or without a bone graft, may achieve successful union. The fusion rate in most of the recently published studies is 85% or greater, and may depend on the presence of infection, deformity, avascular necrosis, and nonunion.

The advantages of ring external fixation for correction of complex deformities of the foot and ankle include the ability to correct severe deformity, perform gradual correction, modify treatment during correction, and minimize neurovascular damage. External fixation can provide opportunities to operate on scarred and contracted tissues, preserve joints and joint function, maintain or gain foot length, and allow weight bearing during treatment.

Distraction osteogenesis methods are indicated in cases of deformity when alternative surgery is not able to produce adequate anatomic restoration and functionality of the foot and ankle. Recent advances in deformity evaluation and techniques of correction may encourage a greater number of surgeons to incorporate distraction osteogenesis into their treatment of complex foot and ankle problems.
