Introduction: Osteochondral lesions of the tibial plafond account for approximately 2.6% of osteochondral lesions in the ankle. There are few cases describing this lesion in the literature, with little information on mechanism of injury, history/physical findings or recommendations for management. Case Presentation: A 17-year-old male competitive soccer player presented with a 6-7 month history of medial ankle pain after an inversion sprain. He presented with locking and giving way of the ankle with weight-bearing and pushing off the foot to the contralateral side...

BACKGROUND: This study assessed the correlation among the patients' perception of the leg length discrepancy (LLD) after total hip arthroplasty (THA) and the anatomical and functional leg length, pelvic and knee alignments, and foot height. METHODS: Patients without significant spinal pathology or previous spine or lower extremity surgery who underwent primary THA (101 patients) were evaluated using EOS images obtained in standing position. All 3-dimensional measures were evaluated and compared for the repeatability and reproducibility and correlation with patients' perception of leg length...

BACKGROUND: Intra-articular Pilon fractures remain therapeutically challenging due to osteochondral fracturing and comminution, marginal impaction, and insult to the soft tissue envelope. The purpose of this study was to compare the efficacy of anterolateral distal tibial locking plates in capturing main fracture fragments in tibial plafond fractures. METHODS: From May 2011 to Dec 2015, 169 OTA C-type pilon fractures met inclusion and exclusion criteria with computed tomographic (CT) scans performed prior to definitive fixation...

There are no accepted methods to grade bone marrow oedema (BMO) and fracture on magnetic resonance imaging (MRI) scans in Charcot osteoarthropathy. The aim was to devise semiquantitative BMO and fracture scores on foot and ankle MRI scans in diabetic patients with active osteoarthropathy and to assess the agreement in using these scores. Three radiologists assessed 45 scans (Siemens Avanto 1.5T, dedicated foot and ankle coil) and scored independently twenty-two bones (proximal phalanges, medial and lateral sesamoids, metatarsals, tarsals, distal tibial plafond, and medial and lateral malleoli) for BMO (0-no oedema, 1-oedema < 50% of bone volume, and 2-oedema > 50% of bone volume) and fracture (0-no fracture, 1-fracture, and 2-collapse/fragmentation)...

The early establishment of the diagnosis of a syndesmotic injury is essential for treatment selection. However, such injuries may not be apparent radiographically. Previous studies have attempted to describe correlations between medial malleolar fracture geometry and syndesmotic disruption. The main objective of this study was to create predictive models for assessing syndesmotic injuries based on an originally described angle, i.e., the medial crural-focal angle (MCFA). This study included 138 ankle fractures involving the medial malleolus...

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...

The morphology of the distal tibiofibular syndesmosis can determine the pathology and mechanism of syndesmotic injury. The present study assessed measurements obtained from computed tomography (CT) images of the normal distal tibiofibular syndesmosis in Japanese subjects. CT scans of 120 right feet with a normal distal tibiofibular syndesmosis obtained from January 2009 to December 2016 were retrospectively assessed at the level 10 mm proximal to the tibial plafond. The incisura fibularis was considered concave when its depth was ≥4 mm and shallow when its depth was <4 mm...

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...

OBJECTIVES: We hypothesize that the anatomic center of the distal tibia is just lateral and anterior to the center of the distal tibia articular surface in the coronal and sagittal planes, respectively, and that placement of the nail along this axis results in improved rates of malalignment when treating distal tibia fractures. DESIGN: Retrospective study. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence...

BACKGROUND: Osteochondral lesions of the tibial plafond (OLTPs) can lead to chronic ankle pain and disability. It is not known how limited ankle motion or joint distraction affects arthroscopic accessibility of these lesions. The purpose of this study was to determine the effects of different fixed flexion angles and distraction on accessibility of the distal tibial articular surface during anterior and posterior arthroscopy. METHODS: Fourteen below-knee cadaver specimens underwent anterior and posterior ankle arthroscopy using a 30-degree 2...

BACKGROUND: A most challenging condition for balancing a varus arthritic ankle is the presence of a defect in the medial tibial plafond. After our initial results with a medial tibial plafondplasty did not fulfill our expectations of success, we hypothesized that adding a correcting supramalleolar osteotomy of the distal tibia would move the loading force to the tibiotalar joint more medially and move the center of rotation of the talus more laterally. In this study, we analyzed midterm clinical and radiographic outcomes in patients with double tibial osteotomy...

BACKGROUND: To investigate changes in lower extremity coronal alignment in patients with unilateral Crowe type IV developmental dysplasia of the hip who underwent total hip arthroplasty with transverse femoral shortening osteotomy. METHODS: We reviewed the preoperative and 1-year postoperative full-length lower extremity radiographs of 25 patients. Femoral offset (FO), mechanical hip-knee-ankle angle, anatomical axis, mechanical axis deviation (MAD), mechanical lateral proximal femoral angle, anatomical medial proximal femoral angle, mechanical lateral distal femoral angle, anatomical lateral distal femoral angle, knee joint line congruency angle, mechanical medial proximal tibial angle, mechanical lateral distal tibial angle, ankle joint line orientation angle, tibial plafond talus angle, extremity length, and pelvic obliquity were measured on both the operative and nonoperative sides...

We report a case of valgus ankle degenerative arthritis due to chronic isolated deltoid insufficiency combined with tibial varus that was treated successfully with ankle joint preserving surgery. A 63-year-old male complained of right lateral ankle pain with 10 minutes of maximal pain-free walking time. The assessed American Orthopaedic Foot and Ankle ankle-hindfoot scale score was 33 points. The ankle joint showed 18° of valgus deformity with 6° of tibia varus. Medial displacement calcaneal osteotomy, supramalleolar open wedge osteotomy, and deltoid ligament imbrication were performed...

BACKGROUND: Medial malleolar fractures are frequent, and their treatment is familiar to the orthopedic surgeon. Lag screw fixation using partially threaded screws remains the standard treatment method for medial malleolar fractures. However, the literature lacks a defined method for selecting lag screw length, relying more so on the empiric choice of the surgeon. AIM: The aim of this study is to help define the ideal lag screw length for medial melleolar fracture fixation...

A large number of articular cartilage defect treatments have been described. However, few have discussed the use of biologic agents implanted into the so-called dependent defect arthroscopically. Furthermore, even fewer of these reports have contained a description for treating dependent osteochondral lesions of the tibial plafond. Generally, these lesions have been treated with either microfracture or debridement, and the long-term outcomes have been less than satisfactory. With new interest in biologic treatments for osteochondral defects, we believe that bone marrow aspirate concentrate combined with a biologic scaffold provides the necessary components to provide healing of these so-called dependent lesions...

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications...
