BACKGROUND: A major complication of foot and ankle arthrodesis is nonunion, which occurs in approximately 12% of cases. Various factors influence a patient's risk for nonunion following foot and ankle arthrodesis. We surveyed international foot and ankle surgeons to determine (1) risk factors perceived most important for nonunion, (2) factors considered absolute contraindications for arthrodesis, and (3) differences among expert groups regarding perceived risk factors and their stratification...

BACKGROUND: Ankle arthrodesis has long been the traditional operative treatment for posttraumatic arthritis, rheumatoid arthritis, infection, neuromuscular conditions, and salvage of failed ankle arthroplasty. It remains the treatment of choice for patients in whom heavy and prolonged activity is anticipated. We present our short term followup study of functional outcome of patients who underwent transfibular ankle arthrodesis for arthritis of ankle due to various indications. MATERIALS AND METHODS: 29 transfibular ankle arthrodesis in 29 patients performed between April 2009 and April 2014 were included in this study...

Ankle arthrodesis is performed to eliminate pain due to end-stage osteoarthritis, regardless of etiology. This procedure remains the reference standard treatment for end-stage ankle arthritis, despite recent advancements in total ankle replacement. The objective of the present study was to retrospectively evaluate the radiographic and clinical fusion rates and time to bony fusion for patients who underwent ankle arthrodesis using an anterior approach with a single column locked plate construct versus crossed lag screws...

We report a case of a complex limb salvage ankle arthrodesis in a patient with Charcot arthropathy. A step-cut osteotomy was performed in order to tackle the issues of anterior tibial bone loss; worsening leg length discrepancy; soft tissue contraction; joint instability and high risk of non-union. The construct formed by the step-cut allowed for the preservation of good bone stock; avoidance of further limb shortening; increased torsional stability and increased surface area for bony union. This resulted in a patient with a stable, plantigrade foot appropriate for footwear...

Today, autogenous bone graft (ABG) is still considered as the gold standard for joint fusion. Recombinant human platelet-derived growth factor-BB (rhPDGF-BB) which is of chemotactic and mitogenic to mesenchymal stem cells and possesses outstanding osteogenetic potentials has been used for ankle and foot fusion in recent years. The goal of this article is to evaluate the safety and efficacy of rhPDGF-BB versus ABG in foot and ankle fusion. The PubMed MEDLINE, EMBASE, Web of Science, and Cochrane Library were systematic searched...

BACKGROUND: The development of valgus tibiotalar tilt following hindfoot arthrodesis is rarely discussed in the literature. The purpose of this study was to determine the incidence of valgus tibiotalar tilt and to evaluate if there were any radiographic predictors for the development of valgus tibiotalar tilt. METHODS: Patients who underwent hindfoot fusion between January 1, 2004 and December 31, 2013 were identified. Charts were reviewed for demographic information and operative details...

Ankle arthrodesis is currently the reference standard treatment for end-stage tibiotalar arthrosis. The fusion rates have varied in the published data from 59% to 100%. We reviewed 60 cases of consecutive anterior ankle arthrodesis using an anterior dual locked plating construct with respect to the fusion rate, time to fusion, pain relief, and complications. The patients were followed up for a mean of 1.1 years (range 16 weeks to 4 years). We found that our fusion rate was 97% for ankles not requiring structural allograft...

BACKGROUND: Screw fixation is a typical technique for isolated talonavicular arthrodesis (TNA), however, no consensus has been reached on how to select most suitable inserted position and direction. The study aimed to present a new fixation technique and to evaluate the clinical outcome of individual headless compression screws (HCSs) applied with three-dimensional (3D) image processing technology to isolated TNA. METHODS: From 2007 to 2014, 69 patients underwent isolated TNA by using double Acutrak HCSs...

Total ankle replacement (TAR) is an alternative to fusion, replacing the degenerated joint with a mechanical motion-preserving alternative. Minimal pre-clinical testing has been reported to date and existing wear testing standards lack definition. Ankle gait is complex, therefore the aim of this study was to investigate the effect on wear of a range of different ankle gait kinematic inputs. Five Zenith (Corin Group) TARs were tested in a modified knee simulator for twelve million cycles (Mc). Different combinations of IR rotation and AP displacement were applied every 2Mc to understand the effects of the individual kinematics...

BACKGROUND: Mueller-Weiss disease is a rarely diagnosed deformity where the navicular bone undergoes spontaneous osteonecrosis in adults. Until now, there is no widely accepted operative treatment for this unusual disease. We aimed to compare clinical and radiological outcomes between the open triple fusion and talonavicular-cuneiform arthrodesis for Mueller-Weiss disease of stage 4. METHODS: During the period from February 2012 to June 2016, 10 patients (11 feet) suffering from Mueller-Weiss disease of stage 4 were treated by the same senior surgeon...

BACKGROUND: Hallux rigidus can be treated using several different methods and the best treatment option depends on the severity of degenerative changes of the metatarsophalangeal (MTP) joint. However, the ideal operative option for advanced hallux rigidus remains debatable. This prospective study was performed to evaluate the intermediate-term clinical outcomes of distal metatarsal osteotomy used as a joint-preserving method for the treatment of advanced hallux rigidus. METHODS: Forty-two cases (39 patients) were followed for more than 3 years after distal metatarsal dorsiflexion osteotomy for advanced hallux rigidus of grade III-IV...

Ankle distraction is an alternative to ankle arthrodesis or total ankle arthroplasty in younger patients with arthritis. Ankle distraction involves the use of external fixation to mechanically unload the ankle joint, which allows for stable, congruent range of motion in the setting of decreased mechanical loading, potentially promoting cartilage repair. Adjunct surgical procedures are frequently done to address lower-extremity malalignment, ankle equinus contractures, and impinging tibiotalar osteophytes. Patients can bear full weight during the treatment course...

The naviculocuneiform articulation is composed of the navicular proximally and the 3 cuneiforms distally. It is not uncommon to perform surgical interventions at this joint for multiple pathologic foot etiologies. To date, no detailed anatomic measurement is available for each cuneiform articulation on the navicular. The purpose of the present study was to present an anatomic description of this complex joint to aid in better surgical understanding and improve surgical outcomes. Ten fresh, frozen, and thawed below-the-knee cadaveric specimens were used for anatomic dissection of the navicular and associated cuneiforms...

Mohamed E Al-Ashhab
Management of severely comminuted, complete articular tibial pilon fractures (Rüedi and Allgöwer type III) remains a challenge, with few treatment options providing good clinical outcomes. Twenty patients with severely comminuted tibial pilon fractures underwent primary ankle arthrodesis with a retrograde calcaneal nail and autogenous fibular bone graft. The fusion rate was 100% and the varus malunion rate was 10%. Fracture union occurred at a mean of 16 weeks (range, 13-18 weeks) postoperatively. Primary ankle arthrodesis is a successful method for treating highly comminuted tibial pilon fractures, having a low complication rate and a high satisfaction score...

BACKGROUND: While nonunion after foot and ankle fusion surgery has been associated with poor outcomes, we are not aware of any longitudinal study on this subject. Thus, we prospectively evaluated the impact of nonunion on clinical outcomes of foot and ankle fusions and identified potential risk factors for nonunion after these procedures. METHODS: Using data from a randomized clinical trial on recombinant human platelet-derived growth factor-BB (rhPDGF-BB; Augment Bone Graft, BioMimetic Therapeutics), union was defined either by assessment of computed tomography (CT) scans at 24 weeks by a reviewer blinded to the type of treatment or by the surgeon's composite assessment of clinical and radiographic findings at 52 weeks and CT findings at 24 or 36 weeks...

BACKGROUND: Bone graft substitutes are often required in patients at risk for nonunion, and therefore, an allograft that most closely mimics an autograft is highly sought after. This study explored the utility and efficacy of a cellular bone allograft used for foot and ankle arthrodesis and revision nonunion procedures in a patient population at risk for nonunion. METHODS: An institutional review board-approved retrospective review of consecutive patients who underwent arthrodesis and revision nonunion procedures with a cellular bone allograft was performed at a single academic institution...
