Custom 3D printed total talus implants have been used successfully as a functional alternative to arthrodesis or amputation in cases of severe talar destruction or loss. However, the ideal material and construct still remains to be elucidated. Current models have been made from aluminum ceramic, cobalt chrome, stainless steel, titanium, or metal combinations. The implants may be constrained (subtalar arthrodesis) or unconstrained (press fit within mortise). They may also be combined with a tibial prosthesis or used in isolation. The majority of currently published case studies examine unconstrained and isolated implants. This case study presents satisfactory 1-y outcomes in 3 cobalt chrome constrained total talar implants used in combination with a tibial prosthesis, and a literature review of total talus replacements.

Radiographic Soft Tissue Thickness is not a Risk Factor for Infection after Primary Total Ankle Arthroplasty.
J Foot Ankle Surg
January 2025
Division of Foot and Ankle, Department of Orthopaedic Surgery, Duke University School of Medicine, Durham, NC, 27710. Electronic address:
As the incidence of total ankle arthroplasty (TAA) for the management of end-stage arthritis is on the rise, identification of risk factors for periprosthetic joint infection (PJI) is essential. There has been limited research exploring the use of radiographic soft tissue thickness in TAA despite its predictive value in other forms of arthroplasty. This study evaluated the predictive capabilities of radiographic soft-tissue thickness for PJI following TAA.

University Center for Orthopaedics, Trauma and Plastic Surgery, University Hospital Carl Gustav Carus at TU Dresden, Dresden, Germany.
Background: Bosworth fractures (BFs) with entrapment of a fibular fragment behind the posterior malleolus (PM) are rare but potentially serious injuries to the ankle. Despite an increased awareness through a more regular use of computed tomography (CT) scanning, there is still a scarcity of clinical outcome studies.
Methods: Over a course of 25 years, data on 23 patients treated for BF at our institutions (mean age 44 years) were collected prospectively.
Limited evidence to support demineralized bone matrix in foot and ankle surgical procedures: A systematic review.
World J Orthop
January 2025
Department of Orthopedic Surgery, NYU Langone Health, New York, NY 10002, United States.
Background: Demineralized bone matrix (DBM) is a commonly utilized allogenic bone graft substitute to promote osseous union. However, little is known regarding outcomes following DBM utilization in foot and ankle surgical procedures.
Aim: To evaluate the clinical and radiographic outcomes following DBM as a biological adjunct in foot and ankle surgical procedures.
Incidence of peroneal tendon dislocation with talus fracture.
Foot Ankle Surg
January 2025
Department of Orthopaedic Surgery and Rehabilitation, Loyola University Medical Center, Maywood, IL, United States.
Background: Traumatic peroneal tendon dislocation (PTD) is known to occur with pilon and calcaneus fractures, however, literature describing PTD in concurrence with injury to the talus remains limited.
Methods: This was a retrospective review of adult patients with operatively treated talus fractures treated at a level I academic trauma center between 2007 and 2021. Charts, radiographs, and advanced imaging, when available, were reviewed for patient demographics, injury characteristics, and complications.
