Michael Corpuz, David Shofler, Jonathan Labovitz, Lawrence Hodor, Kelly Yu
Subtalar joint arthroereisis remains a popular procedure for a flexible flatfoot deformity. Potential complications of the procedure have been discussed in published reports and are often believed to have resulted from shortcomings related to the mechanical properties of the biomaterial, implant size, and/or implant placement. In the present report, we describe the case of a talar neck fracture with migration of the implant after subtalar joint arthroereisis performed 10 years earlier. The 19-year-old patient was treated with implant removal and open reduction internal fixation and bone void filler and recovered unremarkably thereafter...

RANDOMIZED CONTROLLED TRIAL
Thuan V Ly, J Chris Coetzee
BACKGROUND: Open reduction and internal fixation is currently the accepted treatment for displaced Lisfranc joint injuries. However, even with anatomic reduction and stable internal fixation, treatment of these injuries does not have uniformly excellent outcomes. The objective of this study was to compare primary arthrodesis with open reduction and internal fixation for the treatment of primarily ligamentous Lisfranc joint injuries. METHODS: Forty-one patients with an isolated acute or subacute primarily ligamentous Lisfranc joint injury were enrolled in a prospective, randomized clinical trial comparing primary arthrodesis with traditional open reduction and internal fixation...

BACKGROUND: Ankle sprains are the most common injuries in sports and recreational activities. HYPOTHESIS: Ankle osteoarthritis can be caused by ankle ligament lesions. Latency time between injury and osteoarthritis is influenced by the type and side of the injured ligaments. The side of the ligamentous lesion correlates with the hindfoot alignment. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Of a cohort of 247 patients with ankle arthritis, we reviewed data from 30 patients (33 ankles; mean age, 58...

The purpose of our study was to identify the cause of symptomatic ankle arthritis in a consecutive series of patients presenting in a tertiary care setting. Between 1991 and 2004, 639 patients with Kellgren grade 3 or 4 ankle arthritis presented to the University of Iowa Orthopaedic Foot and Ankle Surgery service. The cause of the arthritis was determined based on medical history, physical examination, and imaging studies. To get a sense of the relative prevalence of the etiologies of lower extremity arthritis in our setting, we evaluated the cause of arthritis of all new patients presenting to the University of Iowa Orthopaedic Department from 1999-2004 with arthritis of the ankle, to those with arthritis of the hip or knee during one year...

OBJECTIVE: To review the biomechanical principles that guide fracture fixation with plates and screws; specifically to compare and contrast the function and roles of conventional unlocked plates to locked plates in fracture fixation. We review basic plate and screw function, discuss the design rationale for the new implants, and examine the biomechanical evidence that supports the use of such implants. DATA SOURCES: Systematic review of the per reviewed English language orthopaedic literature listed on PubMed (National Library of Medicine online service)...

The unique biomechanical properties of healthy cartilage ensure that articular cartilage is able to transmit force between the joints while maintaining almost friction-free limb movement. In osteoarthritis, the biomechanical properties are compromised, but we still do not understood whether this precedes the onset of the disease or is a result of it. This review focuses on the physical changes to cartilage with age, disease, and mechanical loading, with specific reference to the increased collagen cross-linking that occurs with age (nonenzymatic glycation), and the response of chondrocytes to physiological and pathological loads...

Displaced fractures of the calcaneous are relatively common injuries that remain a treatment enigma. Virtually all aspects of the management of calcaneal fractures are a source of debate. Contemporary imaging, reduction, and fixation techniques attempt to improve the long term results of these injuries. The complex fracture fragments displace in predictable patterns. Meticulous surgical technique, restoration of extra- and intra-articular anatomy, and obtaining rigid fracture fixation are critical to obtaining satisfactory operative results...

Calcaneal fractures remain among the most challenging fractures encountered by orthopaedic traumatologists, but the technology exists today to treat any isolated calcaneal fracture. Critical to patient outcome is the restoration of the morphologic structure of the entire calcaneus, including the relationship between the articular surfaces and the overall length, width, and height. Open reduction and internal fixation via the extensile lateral approach is the preferred treatment for displaced calcaneal injuries, because it allows superior access to the anterior process, posterior facet, and tuberosity...

Variation in functional stability of the first metatarsocuneiform joint was analyzed between transverse plane deviated (adducted) and corrected first metatarsal positions in a closed kinetic chain model. Six fresh frozen cadaver specimens with intact ankles and feet were fitted with a custom fabricated titanium metatarsal jig, which allowed for manipulation of the first metatarsal in the transverse plane. Specimens were mounted into a custom-made acrylic load frame and axially loaded to 400 N. Radiowave three-dimensional tracking transducers were attached to the following osseous segments: first metatarsal head and base, medial cuneiform, and second metatarsal...

OBJECTIVE: To assess a bedside technique for diagnosing osteomyelitis. DESIGN: We prospectively assessed infected pedal ulcers for detectable bone by probing with a sterile, blunt, stainless steel probe. We then examined the relationship between detection of bone and the presence or absence of osteomyelitis that was defined histopathologically and/or clinically. SETTING: A tertiary care center. PATIENTS: Seventy-five hospitalized diabetic patients with a total of 76 infected foot ulcers were studied...

The results of internal fixation can be adversely affected by implant failure before union takes place. The survival of an internal fixation device depends upon load transfer from fragment to fragment. Techniques that do not provide such a load sharing between implant and bone will lead to failure of the implant. For example, absence of contact between cortices opposite the plate will increase the forces acting on the device which will either pull out, shear or break. This review focuses on the methods of applying implant to bone to achieve stable fixation and thus restore early function without sacrificing reduction and union...

Injuries to the tarsometatarsal (Lisfranc) joint are not common, and the results of treatment are often unsatisfactory. Since no individual is likely to see many such injuries, we decided to make a retrospective study of patients from five different centres. In this way 119 patients with injuries of the Lisfranc joint have been collected. This paper classifies these injuries and describes their incidence, mechanism of production, methods of treatment, results and complications. Sixty-nine of the patients attended for review: 35 of these had been treated by closed methods, 27 had had an open reduction and seven patients had had no treatment...

B J Sangeorzan, S T Hansen
A modified Lapidus procedure was introduced at Harborview Medical Center in 1979 for the treatment of symptomatic hallux valgus with hypermobile first ray. The results of the procedures were reviewed retrospectively in 32 patients with 40 feet that were operated on between 1979 and 1984. Preoperative diagnosis was symptomatic hallux valgus complex with hypermobile first ray in 33 and failed bunion surgery in 7. Follow-up ranged from 30 months to 6 1/2 years. Union of the arthrodesis site occurred in 36 (90%)...

REVIEW
A Manoli
The foot has been mentioned as a site for the development of a compartment syndrome for approximately 9 years. Despite this, very little information exists in the literature containing specifics on the nature of the disorder. Very recent work has shown that crush injuries, forefoot and midfoot fractures and dislocations, and calcaneal fractures are prone to the development of foot compartment syndromes (FCS). The classical clinical signs of pain with passive stretch of the involved muscles, and dysfunction of the nerves that pass through the involved compartments are less helpful in the diagnosis of the syndrome in the foot than elsewhere...

S T Canale, F B Kelly
Seventy-one fractures through the neck of the talus were clinically evaluated and classified on the basis of roentgenographic appearance. The follow-up interval averaged 12.7 years. Good or excellent results were achieved in 59 per cent of the fractures. Accurate anatomical reduction of displaced fractures, if necessary by open reduction and internal fixation, is recommended. Avascular necrosis of the talar body occurred in 52 per cent of the fractures (in two of thirteen non-displaced fractures, in half of the fractures with subluxation or dislocation of the subtalar joint, and in sixteen of nineteen fractures with complete dislocation of the body of the talus)...

I G Yablon, F G Heller, L Shouse
The reason why late degenerative arthritis developed in some patients who had sustained displaced bimalleolar fractures of the ankle was investigated. The roentgenograms indicated that incomplete reduction of the lateral malleolus and a residual talar tilt were present. When bimalleolar fractures were created in cadavera the talus could be anatomically repositioned only when the lateral malleolus was accurately reduced. Fifty-three patients with bimalleolar fractures were treated by anatomically fixing the lateral malleolus with a four-hole plate...

M Allgöwer, P G Spiegel
The recognized goal of any fracture treatment is the restoration of normal function to the injured part(s). Historically, this was first achieved with non-operative techniques and more recently with operative fixation of fractures. Newer systems utilizing the principles of rigid internal fixation and a sophisticated armamentarium have proved useful in fractures of both bones of the forearm, major intra-articular joint fractures and the multiply injured patient. With these methods "fracture disease" (i.e. muscle atrophy, joint stiffness and bony demineralization) is decreased by early mobilization without external support...
