BACKGROUND: Ankle fusion is difficult to achieve in the diabetic Charcot ankle Brodsky type 3a because of the poor quality of the bone and the inability to achieve a stable biomechanical construct. The aim of this study was to report the outcome of ankle fusion using a combination of an intramedullary nail and a circular external fixator in patients with diabetic Charcot arthropathy. METHODS: We prospectively studied 24 patients with diabetic Charcot arthropathy of the ankle who were treated by fusion of the tibiotalar joint using a combined retrograde intramedullary nail and Ilizarov external fixator...

ALK rearrangements occur in up to 10% of spitzoid melanocytic neoplasms. No reported cases have shown homozygous deletion of 9p21 (CDKN2A) or gains of 6p25 (RREB1) or 11q13 (CCND1), which have been associated with aggressive clinical behavior. Here we report two unique cases. Case 1 occurred in a 9-year-old male with a 14-mm nodule on the anterior left thigh. Biopsy revealed an ALK-positive Spitz tumor containing an irregular nodule of densely packed melanocytes with increased mitoses and loss of p16 immunoreactivity...

Radionuclide bone scanning has been used routinely in the evaluation of bone pathology for decades. The greatest strength of the procedure is its extreme sensitivity for bone metabolism, allowing it to distinguish between active and inactive bony abnormalities. The downside of this reliance on abnormal bone turnover is the relative lack of anatomical detail compared with ever-improving CT and MRI technology. Fusion imaging using SPECT/CT (SCT), PET/CT, and PET/MRI offers an opportunity to combine the sensitivity of nuclear medicine examinations with the anatomical detail of CT and MRI...

INTRODUCTION: Hemophilic arthropathy is painful and disabling. We report a retrospective study of ankle fusion with intra- and peri-operative clotting factor perfusion. The objective was to assess the efficacy of maintaining perioperative clotting factor rates close to 100%, and report long-term results. The study hypothesis was that results would be good, without early hemorrhagic complications. MATERIAL AND METHOD: Between 2000 and 2013, 12 ankle fusions were performed in 9 patients, with a mean age of 39 years (range, 19-58 years)...

Metastatic disease to the tibial plafond is rare with few reports in the literature. No consensus exists regarding surgical reconstruction of large structural defects of the ankle due to these lesions, as each treatment must be tailored to the individual patient's goals and prognosis. Cancer metastases pose a unique challenge to limb salvage as there is often bone loss and poor soft tissue quality combined with the need for postoperative adjuvant therapy. The goal of surgery is to obtain early weightbearing, pain relief, and a durable reconstruction that will outlive the patient...

INTRODUCTION: Coronal deformity is considered a relative contraindication for arthroscopic ankle fusion. This study assessed whether preoperative coronal ankle joint deformity influenced the outcome of arthroscopic ankle fusion. METHODS: Ninety-seven patients had 62 arthroscopic and 35 open ankle fusions between 2005 and 2012. Clinical outcomes were prospectively recorded with use of the Ankle Osteoarthritis Scale (AOS) and Ankle Arthritis Scale (AAS) preoperatively and at 6, 12, and 24 months and final follow-up...

BACKGROUND: Hemophilic arthropathy (HA) of the ankle is prevalent in people with hemophilia (PWH). It is frequently severe and incapacitating, due to recurrent bleeding into the ankle articulation during infancy. Around 50% of hemophilic patients suffer from ankle pain and radiological signs of HA. OBJECTIVE: To review current treatment of HA of the ankle in PWH. METHOD: A literature review of hemophilic ankle arthropathy in PWH was performed utilizing MEDLINE (PubMed) and the Cochrane Library...

REVIEW
Christopher L Reeves, Amber M Shane, Ryan Vazales
Much of the current literature suggests that total ankle replacement (TAR) is no longer an inferior or fringe treatment for advanced ankle arthritis compared with ankle fusion, but rather a viable option for recalcitrant arthritic ankle pathology in the correct patient population. In this article, current concepts associated with successful outcomes for TAR are discussed with an emphasis on ankle joint anatomy and biomechanics, preoperative planning and patient selection, understanding pathomechanics and soft tissue balancing, as well as the surgeon's learning curve...

Repair of osteochondral lesions of the talus can be difficult. Smaller lesions respond well to simple arthroscopy and microfracture, whereas larger cystic lesions may require allograft talus replacement or ankle fusions. The lesions in between are more difficult to treat. Autologous chondrocyte implantation and matrix-associated autologous chondrocyte implantation have shown promising results. Future research may include new techniques, pharmacologic intervention, and cell-based therapies, and may be better served with prospective observational studies instead of costly randomized controlled studies...

Distal tibial malalignment can result from posttraumatic malunion, physeal disturbances, congenital or metabolic diseases, and degenerative arthritis. Malalignment leads to an altered load distribution across the joint leading to early ankle joint arthritis. If a substantial part of the joint is salvageable, ankle fusion or joint replacement is not always the best option. Realignment of the distal tibia with a joint-sparing supramalleolar osteotomy is a valuable procedure in correcting deformity at the distal tibia...

Ankle arthritis can be broadly classified as primary arthritis (nontraumatic degeneration) or secondary arthritis (post-traumatic degeneration). A good understanding of the anatomic features and presentations associated with each will assist the surgeon in determining the best course of action for each patient. Many variations of both primary and secondary arthritis can be treated conservatively; however, there are many times when conservative therapy is not adequate. In these cases, ankle arthroscopy may be considered before a joint fusion or replacement...

BACKGROUND: The treatment for the failure of a first metatarsophalangeal joint (MTP1) prosthesis can be complex. There is no consensus regarding the ideal treatment. One of the main issues is the available bone stock after prosthesis removal. The aim of the study was to report the clinical and radiographic results for MTP1 arthrodesis with autologous calcaneus bone graft (bone-block fusion) as a revision procedure of a previous MTP1 implant failure. METHODS: This study included 12 patients diagnosed with failure of a MTP1 prosthesis...

Tenosynovial giant cell tumor (also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis) is a rare soft tissue tumor that arises from the tenosynovium of a tendon sheath or the synovium of a diarthrodial joint. This disease process occurs infrequently in the foot and ankle but can result in significant bone erosion and destructive changes of affected joints. These cases are challenging to treat, because the tumor most commonly presents in young, active patients and can be associated with extensive bone loss...

BACKGROUND: Accessory ossicles off the talus (os trigonum) are a common radiographic finding seen within the foot with variable symptomatology in adult and pediatric patients. Although most studies have examined the incidence of these anatomic variants in a retrospective manner, few have longitudinally followed the behavior of os trigonum over time. The aim of this study was to investigate the incidence, mean age of appearance and fusion, and fusion rate of os trigonum in a large cohort of asymptomatic pediatric patients...

INTRODUCTION: Systemic capillary leak syndrome (SCLS) is a rare condition of unknown etiology defined by sudden episode of hypotension, high hematocrit, and low serum protein concentration due to capillary hyperpermeability. Several treatments have been published for this pathology and eventual compartment syndrome but not for the disabling consequences. This clinical case highlights the negative orthopedic consequences of a severe systemic attack and reports a subsequent deformity treatment option that resulted in the patient quality of life improvement...
