Outcome of surgical treatment of 54 Periprosthetic femoral fractures after total hip arthroplasty at mid term follow-up.

Purpose: The aim of the present study was to review the outcome of the surgical treatment of 54 periprosthetic femoral fractures (PFF) after total hip arthroplasty at a mean follow-up of 45 months. At final follow-up, the clinical outcome was measured using the Harris Hip score (HHS), the Karnofsky score (KS), while, the radiographic results were evaluated using the Beals and Tower's criteria.

Results: There were 13 post-operative complications that occurred in 10 patients with an overall re-operation rate of 11%.

Middle term results of tantalum acetabular cups in total hip arthroplasty following pelvic irradiation.

Objectives: The aim of this study was to evaluate the middle term cup survival, assess the functional implementation and the radiographic evolution of tantalum acetabular cups implanted on patients with a history of pelvic radiotherapy.

Methods: From 2005 to 2013, we performed 12 THA replacements (4 males 8 females; mean age: 46.6 years (range 25-75)) on irradiated bone with Trabecular metal acetabular cups, 8 primary implants and 4 revision implants.

Vascularized fibular autograft as salvage technique in failure of allograft intercalary reconstructions after tumor resections.

Intercalary allografts after diaphyseal resections for bone tumors represent the most frequent option of reconstruction. Main complications are non-unions, fractures and infections. The purpose of the current study was to report our experience with the use of vascularized fibular autograft as rescue technique in failed previous reconstructions after intercalary bone tumor resection of the extremities.

Infected Prostheses after Lower-Extremity Bone Tumor Resection: Clinical Outcomes of 100 Patients.

Background: Infection of megaprostheses after bone tumor resection is a major concern; management is challenging. This study evaluated the survivability from such infections, the microbial isolates, treatment tactics, and outcome of megaprosthesis reconstructions.

Materials And Methods: We studied 1,161 patients retrospectively who underwent megaprosthesis reconstruction for limb salvage after a sarcoma from 1983 to 2010.

Outcome of expandable prostheses in children.

Background: Expandable prostheses offer the advantages of limb-salvage and limb-length equality at skeletal maturity. However, what is the cost for achieving that goal, and in how many children this is achieved?

Materials And Methods: We present 32 children (16 boys and 16 girls; mean age, 9 y) with bone sarcomas of the femur treated with limb salvage using expandable prostheses. The Kotz Growing prosthesis and the noninvasive Repiphysis and Stanmore expandable prostheses were used.
