Hemiarthroplasty for a Comminuted Fracture of the Proximal Humerus

Darren J. Friedman, Jon J. P. Warner
e altri

editore: American academy of orthopaedic surgeons

This title focuses on such areas as: shoulder & upper extremity and trauma. Hemiarthroplasty is a common surgical treatment for certain proximal humerus fractures, including 4-part fracture in older individuals, 3-part fracture associated with osteopenia, head-split fracture, impaction fracture greater than 40 per cent of the articular surface, and anatomic neck fracture. Anatomic reconstruction of proximal humeral anatomy in these fractures is challenging. To enhance tuberosity healing and recreate normal joint mechanics, the surgeon must properly restore the humeral head height, size, offset, and version. In this video, we detail our technique of using hemiarthroplasty for the treatment of proximal humerus fractures. Height is determined by referencing off the pectoralis major insertion, and tuberosities are positioned at roughly 90 degrees to one another. Tuberosity reconstruction and healing is critical to successful functional outcome.

Arthroscopic Suprascapular Nerve Release

Arthroscopic Suprascapular Nerve

Laurent Lafosse

editore: American academy of orthopaedic surgeons

This book focuses on the shoulder & upper extremity.Arthroscopic suprascapular nerve release confers three distinct advantages over the traditional open technique. First, it provides a better visualization of the neurovascular structures and the TSL. As the SSN can be as small as 2 mm, it can be difficult to appreciate via open surgery. This can result in latrogenic injury during dissection of the transverse scapular notch. The magnification of the arthroscope offers better visualization and permits a safer nerve release. The spinal accessory nerve is also not at significant risk during the arthroscopic procedure because the SSN portal is less than 5 cm medial to the SSN. Second, arthroscopic release of the SSN is significantly less invasive, as it does not involve detachment of the trapezius insertion, which create less morbidity than the open procedure. Third, the procedure is performed as an outpatient surgery and in a significantly shorter time than can be achieved with the open technique. The operative time for the first release was approximately 1 hour, but the learning curve has enabled Dr. Lafosse to increase efficiency significantly and to reduce the operative time to under 10 minutes.

Total Hip Arthroplasty in Congenital High Hip Dislocation with Distal Femoral Osteotomy

Nicolas Restrepo Giraldo

editore: American academy of orthopaedic surgeons

This title focuses on such areas as: joint replacement and hip, knee & lower extremity. Dr. Giraldo demonstrates the technique of total hip arthroplasty with distal supracondylar resection osteotomy, which was developed specially for patients who have developmental disease of the hip and severe leg discrepancies and who have never been treated. The procedure he demonstrates is simple and fast with limited blood loss and is specially designed to perform well in all kind of femurs. Dr. Giraldo discusses how this technique can convert a potentially difficult surgical situation into one as easy as a primary hip (cemented or uncemented) while avoiding the future problems of osteotomies in the proximal femur. He also stresses that the main goal is obtaining a good fixation in case of a certain revision in these young patients.

Patient Specific Knee Design

An Evolution in Computer-assisted Surgery

Adolph V. Lombardi, Joanne B. Adams
e altri

editore: American academy of orthopaedic surgeons

This title focuses on such area as joint replacement and hip, knee & lower extremity. Efforts to enhance the surgical technique of total knee arthroplasty while avoiding the negative aspects of computer navigation have led to the development of patient-specific cutting guides. In this study, the authors examine the results of 50 TKAs. Detailed MR imaging of each patients knee is obtained along with several slices through the hip and ankle. From these images, proprietary software creates and orients (in space) virtual 3D models of the femur and tibia. Appropriate implant sizes are determined with the help of the software, and virtual bony resections are mapped to help the surgeon accomplish accurate position and alignment. A preoperative plan with visual images is sent to the surgeon for review. Upon approval, rapid prototyping technology is used to fabricate actual models of the patients distal femur and proximal tibia. Also developed are disposable custom guides that will fit precisely on the patients bone to determine accurate pin placement for the standard resection instrumentation of the implant manufacturer. Preliminary results in 50 TKAs show accurate femoral component sizing and restoration of alignment of 4-8 of valgus in all cases. TKA can be performed with custom jigs in truly patient specific fashion, allowing the surgeon to achieve optimal alignment without violating the intramedullary canal.

Surgical Treatment of Periprosthetic Fractures After Total Hip Replacement

James B. Stiehl

editore: American academy of orthopaedic surgeons

This title focuses on such areas as: joint replacement and hip, knee & lower extremity. Periprosthetic proximal femoral fractures after total hip replacement can be difficult to manage and may have a high complication rate. Duncan/Masri B2 and B3 fractures occur at the lower end of the femoral component and are associated with femoral implant loosening and bone osteolysis. Revision is usually required and long-term bone atrophy and osteolysis may compromise fracture union. Dr. Stiehl describes and demonstrates a surgical technique that splits the entire proximal segment above the fracture with an extended lateral osteotomy. Cerclage wiring allows the distal fragment to withstand the hoop stresses of tight distal implant fixation. A modular taper-fluted femoral modular component is inserted into this distal fragment and assembled to span the gap of the proximal bone loss. The proximal femur fracture is then cable-wired around the proximal prosthesis, and defects are supplemented with strut allografts. Recommendations for postoperative management typically include nonweightbearing for 10 to 12 weeks followed by protected weightbearing until ambulating independently. Dr. Stiehl explains the issues surrounding this surgical technique while the video clearly depicts the details of the approach. This includes exposure of the fracture, extended osteotomy, distal canal preparation, modular implant assembly, and final bone and soft tissue reconstruction.

Orthopaedic Basic Science

Foundations of Clinical Practice

Joseph A. Buckwalter, Regis J. O'Keefe
e altri

editore: American academy of orthopaedic surgeons

The goal of the "Orthopaedic Basic Science: Foundations of Clinical Practice edition 3" is to be a useful, comprehensive, clinically relevant and accessible synthesis of the basic knowledge in orthopaedics. Its main audience is doctors-in-training and orthopaedic surgeons who desire information on what's new in basic science and how it effects their practice. Section topics include Basic Principles in Orthopaedic Surgery, Physiology of Musculoskeletal Tissues and basic principles of musculoskeletal Disease and its Treatment. New to "OBs 3" are chapters on Evidence Based Medicine and Metabolic Bone Diseases and a collection of topic correlated case studies that will be accessible on the web only.
