Metastasis of the distal tibia is quite rare. In this article, we present the case of a 58-year-old woman with distal tibial metastasis located in the posterior malleous caused by breast cancer. She had left ankle pain and nonweightbearing status that had been ongoing for 2 months and showed progression. The patient's Mirels score was 10. Limb salvage surgery was performed by removing the metastatic lesion by posterior ankle incision followed by applying a double plate from the posterior and the medial side of the distal tibia, and the defect was reconstructed with methylmethacrylate. Consequently, good stability was achieved. Radiotherapy consisting of 10 fractions (2000 cGy total) was applied to the distal tibia at postoperative week 3. There were no complications after surgery. No recurrence was observed at the 18-month follow-up of the patient. The Musculoskeletal Tumor Society Score at the 18-month control of the patient was 86%. Use of curettage of the metastatic mass, double-plate application, and defect reconstruction with methylmethacrylate is an effective method for distal tibia metastases located in the posterior malleolus.

Case: A 49-year-old gentleman sustained a closed, right tibia peri-implant fracture with a bent intramedullary nail. This resulted in a 17° valgus and 5° recurvatum deformity with fracture at the distal third of the tibial shaft. The patient underwent closed manipulation with an F-Tool and was reviewed by our unit over the following year.

Background: Implant fixation is often the cornerstone of musculoskeletal surgical procedures performed to provide bony fixation and/or fusion. The aim of this study was to evaluate how different design features and manufacturing methods influence implant osseointegration and mechanical properties associated with fixation in a standardized model in cancellous bone of adult sheep.

Methods: We evaluated the performance of three titanium alloy implants: (A) iFuse-TORQ implant; (B) Fenestrated Sacroiliac Device; and (C) Standard Cancellous Bone Screw in the cancellous bone of the distal femur and proximal tibia in 8 sheep.

Coelurosauria, including modern birds, represents a successful group of theropod dinosaurs that established a high taxonomic diversity and significant morphological modifications. In the evolutionary history of this group, a specialized foot morphology, the arctometatarsus, evolved independently in several lineages and has been considered an adaptation for cursoriality. While its functional significance has been extensively studied, the temporal pattern of this parallel evolution, as well as its origin and influencing factors, remains largely unresolved.

Jaffe-Campanacci syndrome (JCS) is a rare disorder characterized by multiple non-ossifying fibromas (NOFs), café-au-lait spots, and other features such as mental retardation and cryptorchidism. It is often clinically and genetically similar to neurofibromatosis type 1 (NF1), complicating diagnosis. This report presents a 17-year-old male with right knee pain, café-au-lait spots, and axillary freckling.
