Lateral ankle instability is a common entity that can result in degenerative arthritis if left untreated. Acute ligament injuries should primarily be treated nonoperatively with a course of physical therapy and functional bracing. Chronic ankle instability is defined as mechanical or functional and can be diagnosed using a combination of history, physical examination, stress radiographs, and magnetic resonance imaging. After failure of nonoperative treatment, surgical treatment with anatomic ligament repair and inferior extensor retinaculum augmentation has the best clinical outcomes...

INTRODUCTION: Calcaneal fractures constitute the most common fractures in hindfoot. Lots of controversies exist in the management of calcaneal fractures but now-a-days, it is preferable to perform open reduction and internal fixation and early mobilizatation. AIM: To evaluate the functional outcome after open reduction and internal fixation of displaced intra-articular fractures of the calcaneum by locking calcaneal plate. MATERIALS AND METHODS: The study was conducted in the Department of Orthopaedic Surgery from September 2013 to April 2016...

OBJECTIVE: Because there are no epidemiologic data regarding the frequency of ankle osteoarthritis (OA) in a general population, we sought to analyze this disabling condition in a large, well-characterized, community-based cohort of older individuals. METHODS: Cross-sectional data, including ankle radiographs, were from the most recent data collection (2013-2015) of the Johnston County OA Project. Radiographic ankle OA (rAOA) was defined as a Kellgren-Lawrence arthritis grading scale of ≥ 2 on weight-bearing lateral and mortise radiographs...

Citrullination, the post-translational conversion of arginines to citrullines, may contribute to rheumatoid arthritis development given the generation of anti-citrullinated protein antibodies (ACPAs). However, it is not known which peptidylarginine deiminase (PAD) catalyzes the citrullination seen in inflammation. PAD4 exacerbates inflammatory arthritis and is critical for neutrophil extracellular traps (NETs). NETs display citrullinated antigens targeted by ACPAs and thus may be a source of citrullinated protein...

Hypoxia is essential for the development of autoimmune diseases such as rheumatoid arthritis (RA) and is associated with the expression of reactive oxygen species (ROS), due to enhanced infiltration of immune cells. The aim of this study was to demonstrate the feasibility of measuring hypoxia non-invasively in vivo in arthritic ankles with positron emission tomography (PET)/magnetic resonance imaging (MRI) using the hypoxia tracers (18)F-fluoromisonidazole (FMISO) and (18)F-fluoroazomycinarabinoside (FAZA)...

Danica D Vance, J Turner Vosseller
INTRODUCTION: Distal fibula fractures are common orthopaedic injuries that often require open reduction internal fixation (ORIF) to anatomically reduce the fracture and minimize the risk of posttraumatic arthritis. In certain clinical situations, stouter fixation may be advantageous to decrease the risk of fixation failure. In this study, the authors report on 12 patients who underwent distal fibula ORIF with 2 one-third tubular plates. MATERIALS AND METHODS: Twelve consecutive patients who underwent distal fibula ORIF with 2 one-third tubular plates were retrospectively reviewed...

REVIEW
Bryant Ho, John Ketz
Staged primary ankle arthrodesis is a viable option for high-energy pilon fractures that are nonreconstructible, in patients with delay in treatment or multiple medical comorbidities, or in patients with peripheral neuropathy. Small retrospective series demonstrate high union and low wound complication rates, although further studies are needed to determine the long-term results. Ankle arthrodesis offers decreased complication rates while eliminating the potential of posttraumatic ankle arthritis pain.

Besides association with acute rheumatic fever (ARF) and acute glomerulonephritis (APSGN), in up to 40% of cases, Group A β-haemolytic streptococcal (GABHS) infections are also implicated as a trigger for Henoch-Schonlein purpura (HSP). A 7-year-old girl with GABHS throat infection who developed HSP, APSGN and rheumatic carditis is reported. She presented with palpable purpura and arthritis in both ankles and later developed carditis characterised by mitral/aortic regurgitation and glomerulonephritis characterised by mixed nephritic/nephrotic syndrome...

Spontaneous or traumatic hemorrhages into joints that occur in the course of congenital bleeding disorders due to deficiencies of plasma clotting factors lead to early and extensive damage to joints. Arthropathy in those patients most commonly affects the knee, elbow and ankle. Replacement surgery of the damaged joint is the only effective way to treat such advanced changes. Although arthritis of the elbow is quite common, surgery is rarely undertaken; hence relevant reports in the literature are limited to individual or small groups of cases...

Arthrofibrosis of the talocalcaneonavicular joint can follow trauma or surgery of the joint. Arthroscopic release of the lateral half of the talocalcaneonavicular joint is indicated if the painful restriction of hindfoot inversion together with tenderness of the lateral side of the joint that is not controlled with conservative treatment. This procedure is contraindicated in other causes of painful stiffness including post-traumatic arthritis, osteonecrosis, and malunion. This technique includes arthroscopic release of the lateral side of the anterior subtalar joint and the talonavicular joint...

OBJECTIVES: Advances in drug therapy for rheumatoid arthritis (RA) have been encouraging us to preserve the metatarsopharangeal (MTP) joint in correction of forefoot deformities, and original metatarsal shortening offset osteotomy was recommended as one of the conventional surgical options for forefoot deformities in RA cases. The objective of this study was to evaluate short- to mid-term outcomes of modified metatarsal shortening offset osteotomy. METHODS: A retrospective observational study was completed for 80 RA cases (mean follow-up period: 3...

BACKGROUND: Post-traumatic osteoarthritis (PTOA) is responsible for the majority of cases of ankle arthritis. While acute and end-stage intra-articular inflammation has previously been described, the state of the joint between fracture healing and end-stage PTOA remains undefined. This study characterized synovial fluid (SF) composition of ankles after bone healing of an intra-articular fracture to identify factors that may contribute to the development of PTOA. METHODS: Of an original 21 patients whose SF was characterized acutely following intra-articular ankle fractures, 7 returned for planned hardware (syndesmotic screw) removal after bone healing (approximately 6 months) and consented to a second bilateral SF collection...

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...

BACKGROUND: Osteoid osteoma (OO) is a common benign bone tumour that is rarely found in the talus. Its nidus is difficult to detect on early imaging. The atypical symptoms of OO and the presence of concurrent trauma or sports injuries may lead to misdiagnosis and delayed treatment. We herein analyse a case of misdiagnosis of OO of the talus and discuss how to improve the early diagnosis of this rare lesion, thereby permitting rapid treatment. CASE PRESENTATION: A 23-year-old man with a history of left ankle sprains and chronic pain was diagnosed with another ankle sprain and managed conservatively based on normal X-ray findings...

Early-stage varus ankle arthritis can usually be treated with a medial, open-wedge, valgus, distal tibial osteotomy; however, the value of adding a fibular osteotomy has been debated. We sought to determine the increase in the maximum medial osteotomy gap and correction angle provided by fibular osteotomy. In 3 sequential experiments on 12 fresh cadaveric legs, we first performed a medial open-wedge, valgus, distal tibial osteotomy alone. Second, we added a transverse fibular osteotomy. Finally, we added a blocked fibular osteotomy...
