Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources...

Medial open wedge high tibial osteotomy (MOWHTO) is a commonly performed procedure for symptomatic medial compartment osteoarthritis (OA). However, little is known about its effects on ipsilateral ankle or hindfoot. The aim of our study was to determine the incidence of ankle or hindfoot problems after MOWHTO and examine its association with radiological indices. Thirty-five knees (32 patients) undergoing navigated MOWHTO were evaluated for the presence of new-onset ankle or hindfoot symptoms after surgery...

BACKGROUND: Diagnosis of distal tibiofibular syndesmotic injuries includes assessment of radiographs; however, there exist no agreed on standard diagnostic criteria. Previous studies lack consistency with radiographic evaluation methods. The dynamic nature of the ankle joint supports analyzing anatomical parameters using weight-bearing films to assess for tibiofibular syndesmotic integrity. METHODS: Weight-bearing tibiofibular syndesmosis radiographs of 39 male and 40 female patients were retrospectively analyzed by 3 investigators, at different levels of orthopaedic training...

BACKGROUND: Several methods are commonly used to predict lower-limb-length discrepancy (LLD) on pelvic radiographs. It is not clear how the lower-limb length of patients with unilateral developmental dislocation of the hip (DDH) changes and whether a pelvic radiograph is reliable to predict LLD. In this study, we analyzed the characteristics of LLD in patients with unilateral DDH by measuring full-length standing anteroposterior radiographs. METHODS: The radiographic data of all patients with unilateral DDH who met the inclusion criteria from March 2011 to May 2016 were retrospectively reviewed...

OBJECTIVES: Osteochondral lesions of the distal tibial plafond (OLTP) are rare and far less common than osteochondral lesions of the talus. Literature data do not report clinical records with significant number of cases and follow-up. The aim of our study was to evaluate clinical and MRI outcomes following arthroscopic treatment of distal tibia osteochondral lesions and to report our results with treating these rare lesions. METHODS: Between October 2010 and November 2011, a consecutive series of 27 patients, 15 males and 12 females, were treated arthroscopically with the one-step BMDCT for OLTPs...

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...

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...
