Pelvic Chondrosarcoma Treated by En Bloc Resection with Patient-Specific Osteotomy Guides and Reimplantation of the Extracorporeally Irradiated Bone as an Osseocartilaginous Structural Orthotopic Autograft: A Report of Two Cases with Description of the Surgical Technique.

Primary tumors of the pelvis are considered difficult to treat due to the complex anatomy and the proximity of important neurovascular structures. The surgical armamentarium for the treatment of these tumors has evolved with the help of cutting-edge technology from debilitating hemipelvectomies to solutions such as precise resections guided by patient-specific instruments or computer navigation and reconstruction by modular prostheses, 3D-printed custom-made implants, or orthotopic autograft reimplantation after extracorporeal irradiation. Different combinations of these techniques have been described in the literature with various rates of success.

Acute leg compartment syndrome after CT-guided core needle biopsy of a giant cell tumor of the proximal fibula.

Imaging-guided percutaneous core needle biopsy (CNB) is the preferred diagnostic method for bone and soft tissue tumors. In less than 1% of cases, complications are clinically significant and include mainly haema-toma and bleeding. We present a case of acute compartment syndrome (ACS) following CNB of the proximal fibula.

Advantages of patient-specific cutting guides with disposable instrumentation in total knee arthroplasty: a case control study.

Background: Total knee arthroplasty (TKA) is most frequently planned using conventional two-dimensional weight-bearing lower limb radiographs and is performed with conventional femoral and tibial cutting guides. Questions have been raised about the accuracy of conventional TKA instrumentation and planning for an anatomically standard or complex joint. Use of computed tomography (CT)-based three-dimensional (3D) templating and patient-specific cutting guides printed in 3D has shown improved postoperative lower limb alignment parameters.

Total Hip Arthroplasty for Bilateral Femoral Neck Stress Fracture: A Case Report and Review of the Literature.

Femoral neck stress fractures (FNSFs) can be treated conservatively or surgically, depending on initial displacement and patient condition. Surgical treatment options include internal fixation, with or without valgus osteotomy or hip arthroplasty, either hemi or total. The latter is mainly considered when initial treatment fails.

[The irreducible ankle dislocation: beware of the Bosworth injury].

A luxation fracture of the ankle characterized by a dislocation of the fibula posterior to the tibial tubercle is defined as a Bosworth injury. The Bosworth fracture is a frequently overlooked complex injury of the ankle joint. Associated injuries such as a pilon fracture and posterior malleolus fracture have rarely been reported.

Are the Cumulated Ambulation Score and Risk Assessment and Prediction Tool useful for predicting discharge destination and length of stay following total knee arthroplasty?

Background: Postoperative management of patients undergoing total knee arthroplasty (TKA) is continually changing. Costs related to TKA are driven by implant cost, operating room cost, hospital length of stay (LOS), and rehabilitation approach. Discharges to rehabilitation centers have declined significantly in recent years.

Cementless short-stem total hip arthroplasty in the elderly patient - is it a safe option?: a prospective multicentre observational study.

Background: Due to its bone preserving philosophy, short-stem total hip arthroplasty (THA) has primarily been recommended for young and active patients. However, there may be benefits for elderly patients given a less invasive operative technique due to the short curved implant design. The purpose of this study was to compare the clinical and radiological outcomes as well as perioperative complications of a calcar-guided short stem between a young (< 60 years) and a geriatric (> 75 years) population.

Association of Bosworth, Pilon, and Open Talus Fractures: A Very Unusual Ankle Trauma.

Introduction: A Bosworth fracture-dislocation is a rare lesion resulting in a fixed dislocation of the distal fibula behind the posterior tibial tubercle. Only few cases have been reported showing an associated consequent fracture, namely, a pilon or a medial malleolus fracture.

Case Report: We present a case report of a patient with an unusual combination of a Bosworth injury with a pilon fracture and an open multifragmentary talus fracture and our approach for open reduction and internal fixation.

Simultaneous Ipsilateral Quadriceps and Triceps Tendon Rupture in a Patient with End-Stage Renal Failure.

Introduction: Quadriceps tendon ruptures (QTR) frequently occur in patients with end-stage renal failure, while triceps brachii tendon ruptures (TTR) are less common. This is the first properly documented report of a simultaneous ipsilateral traumatic rupture of both of these tendons.

Case Report: A 50-year-old patient, on hemodialysis for end-stage renal failure, fell on his right side.
