BACKGROUND: Plantar heloma is a keratotic disorder that can be described as a circumscribed area of thickening with a central core that may penetrate the dermis. Although often considered a minor complaint, longstanding lesions can be debilitating and severely impact on person's quality of life. We present the first retrospective case series at long-term follow-up about the use of plantar lipofilling as a treatment for metatarsalgia caused by plantar heloma. MATERIALS AND METHODS: Six patients affected by plantar heloma associated to external metatarsalgia underwent plantar lipofilling...

Templating plays a key role in surgery that is often underestimated. There is a difference between planning and templating: in the first not only the hip is considered but involves the evaluation of the patient in its entirety. Templating instead consists of calculating the position of the implant in order to place it in the best possible position. Fundamental is a correct X-ray of the pelvis, which must follow certain standards. For traditional templating, drawings on appropriately enlarged transparent implants were provided by the prosthesis manufacturer...

In 1983, Fulkerson introduced a technique of tibial tubercle osteotomy performed according to an inclined plane with respect to frontal plane. Due to obliquity of the osteotomy plane, this procedure allows both anterior and medial transfer of the tibial tubercle. The purpose of the study was to investigate the influence of the different degrees of the oblique plane of osteotomy on anterior displacement and the contact surface area of tibial tubercle. Synthetic bones were used for the study. An osteotomy of the tibial tubercle (TT) was performed in each specimen...

PURPOSE: There are certain risk factors responsible for patella instability that should be identified before choosing the most appropriate treatment. METHODS: We evaluated 83 skeletally immature patients who, after two or more patellar dislocation episodes, underwent surgical treatment to address the condition of patellar instability. Each patient was evaluated for patellar instability risk factors using the Balcarek patellar instability severity score. Evaluation of patellar instability included knee MRI to systematically identify anatomical risk factors...

PURPOSE: To describe a new surgical technique for osteochondral lesions of the ankle, using bone marrow concentrate on a scaffold and homologous bone graft positioned through a retrograde approach. Many surgical options for ankle osteochondral lesions have been described, and the ideal treatment is still debated. Bone marrow stimulating techniques are recommended for cystic lesions, with some concerns regarding the healing potential of the subchondral bone. In case of wide osteochondral defects, regenerative solutions are preferred but a massive chondral debridement is usually required...

Hypersensitivity to orthopedic devices is a rare condition with an underestimated incidence due to the lack of diagnostic guideline and ambiguous clinical manifestations. Although hypersensitivity to metal is common, a few cases of hypersensitivity reactions have been reported after spinal instrumentation. Spinal fusion and stabilization require a wide range of devices such as screws, wires, bands, and artificial disk replacement devices. Spinal instrumented surgeries are different from total joint arthroplasty in several aspects such as degree and pattern of motion, loading environment, and adjacent tissues with distinct characteristics...
