Single-Incision Double-Plating Approach in the Management of Isolated, Closed Osteoporotic Distal Femoral Fractures.

Geriatr Orthop Surg Rehabil 2018 11;9:2151459318799856. Epub 2018 Nov 11.

Ain-Shams University, Cairo, Egypt.

Introduction: Distal femoral fractures in elderly population had recorded an increase in incidence in the last 2 decades. Lateral distal femoral locking plating is considered one of the best options especially when dealing with comminuted fractures but varus collapse of the medial femoral condyle occurs frequently in patients with osteoporosis. Anatomical reduction of the fracture with stable rigid fixation using double-plating approach allows early mobilization of geriatric population and prevents varus collapse minimizing the comorbidities in such fractures.

A large knee osteochondral lesion treated using a combination of osteochondral autograft transfer and second-generation autologous chondrocyte implantation: A case report.

Regen Ther 2019 Jun 20;10:10-16. Epub 2018 Nov 20.

Department of Sports Medicine, Kameda Medical Center, Chiba, Japan.

Background: Full-thickness knee cartilage defects greater than 4 cm are best treated with autologous chondrocyte implantation (ACI). Since the articular cartilage surrounding the site of implantation does not always have the normal thickness desirable for successful engraftment, there may be benefit in combining ACI with osteochondral autograft transfer, which provides immediate restoration of condylar contour and mechanical function.

Case Presentation: A 19 year-old male who sustained a traumatic anterolateral femoral condyle osteochondral fracture underwent arthroscopic knee surgery three months after injury to harvest healthy cartilage to be sent to the Japan Tissue Engineering Co. Read More

A Quartet of Elastic Stable Intramedullary Nails for More Challenging Pediatric Femur Fractures.

J Pediatr Orthop 2019 Jan;39(1):e12-e17

Children's Healthcare of Atlanta.

Introduction: The insertion of 2 elastic stable intramedullary nails (ESINs) is a common treatment for pediatric femur fractures. However, the use of this technique in length-unstable or metadiaphyseal fractures has historically been associated with higher complication rates. To improve stability, the addition of a third ESIN has been assessed biomechanically and clinically, but the addition of a fourth nail has only been evaluated biomechanically. Read More

Feasibility of Magnetic Resonance Imaging Monitoring of Postoperative Total Knee Arthroplasty without Metal Artifacts: A Preliminary Study of a Novel Implant Model.

Biomed Res Int 2018 23;2018:8194670. Epub 2018 Oct 23.

Department of Bone and Joint Surgery, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Background: Although magnetic resonance imaging (MRI) can provide superior detailed images of tissues without ionizing radiation, the imaging evaluation of total knee arthroplasty (TKA) complications and posttherapy changes can be limited because of abundant artifacts on MRI scans due to metallic implants and endoprosthesis in limb salvage and fracture fixation. This study aimed to develop a novel model of TKA using a polyetheretherketone- (PEEK-) on-highly cross-linked polyethylene (HXLPE) implant and to investigate its feasibility for MRI monitoring of peri-implant bone formation, the healing process, signs of infection, and tumor recurrence after TKA.

Methods: Three skeletally mature goats underwent TKA with the PEEK-on-HXLPE implant. Read More

A novel subchondral bone-grafting procedure for the treatment of giant-cell tumor around the knee: A retrospective study of 27 cases.

Medicine (Baltimore) 2018 Nov;97(45):e13154

Department of Orthopedics, Zhongnan Hospital, Wuhan University, Wuhan, Hubei, China.

The vast majority of giant-cell tumors occur around the knee and characteristically affect the subchondral bone. Thermal damage to the articular cartilage arising from the application of polymethylmethacrylate (PMMA) or extensive intralesional curettage presents a challenging problem to orthopedic surgeons and patients due to compliance issues. For this reason, we developed a new subchondral bone-grafting procedure to restore massive bone defects and reduce degenerative changes in the knee. Read More

Prehospital triage for mass casualty incidents using the META method for early surgical assessment: retrospective validation of a hospital trauma registry.

Eur J Trauma Emerg Surg 2018 Nov 7. Epub 2018 Nov 7.

Unit for Research in Emergency and Disaster, Department of Medicine, Public Health Area, Faculty of Medicine, Universidad de Oviedo, C/ Julián Clavería, 6, 33006, Oviedo, Spain.

Background: In mass casualty incidents (MCI), death usually occurs within the first few hours and thus early transfer to a trauma centre can be crucial in selected cases. However, most triage systems designed to prioritize the transfer to hospital of these patients do not assess the need for surgery, in part due to inconclusive evidence regarding the value of such an assessment. Therefore, the aim of the present study was to evaluate the capacity of a new triage system-the Prehospital Advanced Triage Method (META)-to identify victims who could benefit from urgent surgical assessment in case of MCI.

Use of Magnetic Growing Intramedullary Nails in Compression During Intercalary Allograft Reconstruction.

Orthopedics 2018 Nov 7;41(6):330-335. Epub 2018 Nov 7.

Traditionally, intercalary allograft reconstruction after tumor resection has had a high rate of complications, particularly nonunion. Plate and intramedullary nail fixation have been used alone and in combination to improve union rates. This study sought to evaluate a new technique that uses a magnetic growing intramedullary nail to compress the osteotomy sites to aid in healing and to answer 2 questions: (1) What is the union rate and the time to union when using magnetic growing intramedullary nails? (2) What complications occur with this technique? Eight patients with 15 osteotomy sites with a minimum follow-up of 14 months were retrospectively reviewed. Read More
