OBJECTIVE: Pseudolesions of joints are known as focal irregularities of chondral or subchondral bone in typical joint areas and occur frequent but without clinical relevance. This study aims to report the prevalence and describe MRI findings of a previously unreported chondral, mostly posterior located pseudolesion of the distal tibia, and to define criteria to distinguish it from pathologic osteochondral lesions, as well as from another known pseudolesion of this area - the so called "Notch of Harty"...

INTRODUCTION: Controversy exists around which distal tibial fractures are pilon fractures. We evaluated views to define a pilon fracture and support the development of standards of care. METHODS: Views regarding the characteristics of a pilon fracture and acute soft tissue management were determined through a questionnaire. This was trialled, approved by the British Orthopaedic Foot and Ankle Society and distributed to its members. This was also distributed nationally as part of the ENFORCE study...

BACKGROUND: Malunion of tibial pilon fracture, especially with a large cartilage loss of the tibial plafond, is a tough clinical conundrum. This study describes a joint-preserving technique that mainly involves corrective intraarticular osteotomy and osteoperiosteal iliac autograft transplantation for treating these generally considered unreconstructable tibial plafond. METHODS: Sixteen patients with an average age of 33.6 years who were treated with this joint-preserving method between 2013 and 2020 were retrospectively analyzed...

CASE: A 25-year-old male pole vaulter presented with several months of right ankle pain. Radiographs showed an anterior tibial osteophyte with a small intra-articular body suggesting impingement. Weight-bearing computed tomography (CT) revealed an associated tibial plafond stress fracture. Subsequent arthroscopy with osteophyte resection and loose body removal significantly improved symptoms, and he gradually resumed training. CONCLUSION: Stress fractures should always be considered in athletes with ankle pain...

OBJECTIVE: To define a novel radiographic measurement, the posterior cranial vertical line (PCVL), in an asymptomatic adult population to better understand global sagittal alignment. METHODS: We performed a multicenter retrospective review of prospectively collected radiographic data on asymptomatic volunteers aged 20-79. The PCVL is a vertical plumb line drawn from the posterior-most aspect of the occiput. The horizontal distances of the PCVL to the thoracic apex (TA), posterior sagittal vertical line (PSVL, posterosuperior endplate of S1), femoral head center, and tibial plafond were measured...

BACKGROUND: Placement of clamp forceps along the transsyndesmotic (TS) axis reduces the risk of iatrogenic syndesmotic malreduction during ankle fracture surgery with tibiofibular diastasis. This study aimed to measure the difference between the TS axis and the axis determined by an intraoperative fluoroscopic technique using the center-center (CC) method. We also compared the values obtained when the CC method was performed at different heights from the tibial plafond. METHODS: We evaluated the computed tomography scans of 150 patients with normal syndesmosis...

BACKGROUN: Few studies have comprehensively examined how alignment beyond the ankle joint changes after Total knee arthroplasty (TKA). This retrospective study aimed to answer the questions: (1) do the radiological parameters beyond the ankle joint, including the weight-bearing line at the ankle joint level, change after TKA in varus knee osteoarthritis? (2) does the lower extremity alignment correlate with alignment beyond the ankle joint?. HYPOTHESIS: Our hypothesis was that TKA altered the radiological parameters beyond the ankle, which correlated with the lower extremity alignment...

The focal dome osteotomy allows deformity correction through frontal plane rotation, and if needed, anterior or posterior translation. This percutaneous technique allows extracapsular ankle realignment with minimal soft tissue dissection. While circumventing a standard anterior incision, this technique encounters soft tissue structures that must be considered. Focal dome osteotomies were simulated on ten fresh-frozen below the knee cadavers. Centered proximal to the tibial plafond at the physeal scar, a radial arm using a four-hole Rancho cube was used to map the dome...

Tibial pilon fractures are difficult to treat. These fractures are associated with a high frequency of soft tissue complications. Therefore, two-stage surgery and less invasive surgical strategies using external fixation have been reported. The patient was a 79-year-old man. The right tibial pilon fracture was diagnosed as AO/OTA 43C3.1, Rüedi and Allgöwer type 2. He was treated with a low-profile mini-fragment plate and circular (Ilizarov type) external fixation. Herein, we report on a combination of these two methods: circular external fixator with low-profile mini-fragment plate fixation...

Recently, total talar prosthesis has been proposed to substitute the talus during the management of complex talar lesions such as talar extrusion, comminuted talar fractures, or avascular necrosis. Herein, we report two cases of talar extrusion treated with total talar replacement after a high-intensity trauma. Both cases subsequently required revision surgery due to degenerative changes of the tibial plafond (arthrodesis in the first case, conversion to a total ankle prosthesis in the latter). We report and analyze the literature concerning total talar replacement to discuss strategies that could help improve prosthesis survival and reduce the incidence of osteoarthritis...

CASE: A 38-year-old male patient presented with severe ankle pain 13 years after a total ankle arthroplasty (TAA). Radiographic evaluation revealed loosening of the implant and extensive osteolytic lesions. The medial tibial plafond and malleolus were reconstructed using a fresh-frozen femoral head graft, and revision TAA was performed. The midterm results were satisfactory, with adequate integration of the allograft and stable implant components. CONCLUSION: The use of the allograft technique in revision TAA is feasible in the presence of severe bone loss, including the malleoli, and allows firm component fixation of the reconstructed bone...

Pilon fractures are complex injuries that require an individualized approach to treatment to avoid complications and achieve good outcomes. Staged open reduction internal fixation remains the gold standard for most cases to achieve anatomic articular reduction while minimizing soft tissue complications and infection. Careful preoperative planning based on computed tomography dictates the surgical approach for reduction. A subset of cases may be amenable to early definitive or provisional open reduction and internal fixation based on fracture pattern...
