BACKGROUND: Ankle arthrodesis is considered by many to be the standard operative treatment for end-stage ankle arthritis. The purpose of this study was to perform a new technique for ankle joint surface and determine the outcome for the union rates of ankle arthroscopic arthrodesis. METHODS: A total of 68 patients with posttraumatic arthritis, primary osteoarthritis, and rheumatoid arthritis were treated by ankle arthroscopic arthrodesis between May 2007 and December 2012...

Subtalar arthrodesis is the mainstay for treatment of a variety of hindfoot problems associated with arthritis, however with an unpredictable if not high rate of nonunion. This article covers the use of adipose-derived stem cells as an adjunct or alternative to autologous or other bone grafting materials. Promising development and encouraging data exist with respect to the use of adipose-derived mesenchymal stem cells for bone arthrodesis, which is discussed in more detail in the article.

Foot and ankle fusion procedures often incorporate autogenous bone graft to help achieve bony union. Pain and morbidity associated with graft harvest have resulted in decreased autograft use as alternative bone graft substitutes have become available. Recently B2A peptide-coated ceramic granules have been developed and investigated. B2A, a bioactive synthetic multi-domain peptide acting on bone morphogenetic protein receptors of osteoblast precursor cells, amplifies the cell response to bone morphogenetic proteins...

BACKGROUND: Extensile open approaches to reduce and fix intra-articular calcaneal fractures are associated with high levels of wound complications. To avoid these complications, a technique of percutaneous reduction and fixation with screws alone was developed. This study assessed the clinical outcomes, radiographs, and postoperative CT scans after operative treatment with this technique. METHODS: 153 consecutive patients with 182 intra-articular calcaneal fractures were reviewed...

Introduction. Ankle arthrodesis is performed in a variety of methods. We propose a new technique for tibiotalar arthrodesis using a newly designed intramedullary nail. Methods. We proposed development of an intramedullary device for ankle arthrodesis which spared the subtalar joint using a sinus tarsi approach. Standard saw bones models and computer assisted modeling and stress analysis were used to develop different nail design geometries and determine the feasibility of insertion. After the final design was constructed, the device was tested on three cadaveric specimens...

Single, double, and triple hindfoot arthrodeses are used to correct hindfoot deformities and relieve chronic pain. However, joint fusion may lead to dysfunction in adjacent articular surfaces. We compared range of motion in adjacent joints before and after arthrodesis to determine the effects of each procedure on joint motion. The theory of moment of couple, bending moment and balanced loading was applied to each of 16 fresh cadaver feet to induce dorsiflexion, plantarflexion, internal rotation, external rotation, inversion, and eversion...

Arthroscopic subtalar arthrodesis is gaining in popularity based on evidence of bone fusion in over 90% of cases, with a shorter time to healing, a simpler postoperative course, and fewer complication compared to open surgery. Two arthroscopic techniques have been reported: one with the patient in lateral decubitus and lateral portals and the other with the patient prone and posterior portals. The objective of this technical note is to describe these two techniques, with emphasis on the specific characteristics of each...

Locking plate fixation is becoming more popular for fixation of lower extremity osteotomies. The present study evaluated locking plate fixation compared with screw fixation in the medial displacement calcaneal osteotomy procedure, measuring the outcomes and rate of hardware removal. The procedure was performed on 30 patients, 31 times, with 17 undergoing single screw fixation and 14 undergoing locking plate fixation. The return to activity was 6.87 ± 1.43 months, including some patients for whom running was their main activity...

BACKGROUND: Joint compression is an essential element of successful arthrodesis. Although subtalar joint compression generated by conventional screws has been quantified in the laboratory, compression obtainable with headless screws that rely on variable thread pitch to achieve bony contact has not been assessed. This study measured subtalar joint compression achieved by 2 posteriorly placed contemporary headless, variable-pitch screws, and quantified additional compression gained by placing a third screw anteriorly...

BACKGROUND: Tibiotalocalcaneal arthrodesis with headless compression screws has not been previously reported. We hypothesized that these screws could be suitable for tibiotalocalcaneal arthrodesis because of their special design. This study aimed to evaluate the clinical outcomes of patients undergoing tibiotalocalcaneal arthrodesis with headless compression screws for the treatment of severe arthropathy of the ankle and subtalar joint. METHODS: From 2010 to 2015, 23 patients with severe ankle and subtalar arthropathy underwent tibiotalocalcaneal arthrodesis...

Richard Walter, Stephen Parsons, Ian Winson
Arthroscopic approaches to subtalar, double, and triple arthrodesis allow relative preservation of the soft tissue envelope compared with traditional open approaches. The surgical technique involving the use of a 4.5-mm 30° arthroscope via sinus tarsi portals is described. All 3 joints of the triple joint can be prepared for fusion with motorized burrs. Rigid fixation is achieved with cannulated screws. High union rates and low complication rates have been reported.

BACKGROUND: Fractures of the distal tibia, ankle, and foot sustained through a high-energy mechanism can be extremely debilitating, and ankle and/or subtalar fusion may be indicated if the limb is deemed salvageable. Functional outcomes among this population are often poor. The purposes of this study were to evaluate the effect of an advanced rehabilitation program combined with the use of a custom ankle-foot orthosis for patients with ankle or subtalar fusion on selected physical performance measures and patient-derived outcome measures and to determine if the response to treatment was predicated upon the type of fusion...

We often see painful ankle joint destruction with painful hindfoot valgus deformity in rheumatoid arthritis. Our policy in such cases has been to first correct the hindfoot deformity in the subtalar joint with fusion, but then ankle joint pain has been observed. Two women with rheumatoid arthritis underwent correction and fusion surgery for hindfoot valgus deformity. They had been using wheelchairs because of severe pain in the ankle joint and hindfoot despite extensive medical treatment. After surgery, both patients complained of no pain in the hindfoot...

: Hindfoot (tibiotalocalcaneal or TTC) arthrodesis is commonly used to treat concomitant arthritis of the ankle and subtalar joints. Simultaneous fusion of both joints can be difficult to achieve especially in patients with impaired healing due to smoking, diabetes mellitus, or Charcot neuroarthropathy. Conventional intramedullary fixation devices allow for compression to be applied at the time of surgery, but this compression can be lost due to bone resorption or settling, leading to impaired healing...

BACKGROUND: Previous hindfoot surgeries present a unique challenge to hindfoot arthrodesis, as the patients may have multiple incisions around the hindfoot. In high-risk patients with compromised soft tissues, a posterior approach can provide an alternative for a fresh soft tissue plane for the surgery. The use of a blade plate construct is widely accepted; however, there are limited data supporting the use of a posterior approach. QUESTIONS/PURPOSES: We asked (1) what proportion of patients treated with this technique achieved osseous union; (2) what complications were observed; (3) were any patient-demographic or health-related factors associated with the likelihood that a patient would have a complication develop? METHODS: Between December 2001 and July 2014, 42 patients received a posterior blade plate...

UNLABELLED: Subtalar joint distraction arthrodesis has been well reported with use of structural iliac crest or local autologous bone graft for malunited calcaneal fractures. Early reports for structural allograft did not yield good, consistent results, leading to a subsequent lack of recommendation in previous literature. Newer studies have had promising results utilizing femoral allograft as an alternative to autogenous bone graft. We performed a retrospective chart review on 10 patients (12 feet) undergoing subtalar joint distraction arthrodesis with femoral neck allograft for malunited calcaneal fractures...

BACKGROUND: Subtalar arthrodesis is a standard treatment for subtalar arthritis. Both open and arthroscopic techniques have been described and are commonly used. The cases of a consecutive series of 121 patients treated with either open or posterior arthroscopic techniques are presented with functional outcomes and complications. MATERIALS: A retrospective chart review with prospectively collected data was performed for 121 consecutive patients (129 feet) who underwent subtalar arthrodesis with open (60 feet in 57 patients) or arthroscopic (69 feet in 64 patients) techniques between 2001 and 2014...

Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores...
