A novel constrained acetabular liner design with increased range of motion.

One treatment strategy for recurrent dislocation after total hip arthroplasty is the use of a constrained acetabular component. A major drawback of currently available constrained components is the limited range of motion (ROM). We present a novel constrained component that employs a monopolar, highly cross-linked polyethylene liner with cutouts oriented to allow increased ROM, while maintaining constraint against dislocation. ROM and lever-out tests comparing this novel design with a conventional constrained component showed that the cutaway monopolar component allowed ROM substantially greater than a currently available design. The lever-out torque for the cutaway monopolar constrained component was 243% higher than the conventional constrained component. This novel constrained acetabular component offers promise for providing excellent constraint against dislocation, while maintaining a wide ROM.

An electronic database for outcome studies that includes digital radiographs.

We report on acquisition of key data from the clinical medical record, surgical data, radiologic studies, and patient surveys for a novel digital total hip arthroplasty (THA) registry that includes electronic capture of digital radiographic images into a database on an internet platform for query. We now have the ability to collect demographic and operative data, including the operative note, discharge summary, surgery data, and Digital Imaging Communications in Medicine (DICOM) radiology images. Steps are being completed to assemble office encounters, hospital procedural codes, and implant bar codes. Two examples include a THA surgery record and a THA outcome study with plain radiograph set. Analysis of such data could suggest ways to improve clinical practice.

Chest wall deformities.

Children present with chest wall deformities to their pediatrician because of physiologic and psychologic causes. We have a 22-year experience in the operative management of more than 300 of these children. Initial evaluation should accurately categorize the deformity, determine the severity, assess for associated problems and refer the child at an appropriate time for further management. Pectus carinatum is the most common deformity that can cause physical pain from an intercostal neuropathy and psychologic pain from the unsightly protuberance. Poland syndrome is managed by early correction of the hand deformity and later correction of the chest wall deformity if necessary for psychologic or functional reasons. Jeune syndrome and failure of sternal fusion may have severe associated cardiopulmonary compromise. Each should be corrected in infancy for the best results.

Olecranon fractures: treatment options.

Fractures of the olecranon process of the ulna typically occur as a result of a motor-vehicle or motorcycle accident, a fall, or assault. Nondisplaced fractures can be treated with a short period of immobilization followed by gradually increasing range of motion. Open reduction and internal fixation is the standard treatment for displaced intra-articular fractures. Stable internal fixation with figure-of-eight tension-band wire fixation for simple transverse fractures allows early motion to minimize stiffness. Use of two knots produces symmetric tension at the fracture site and provides more rigid fixation than a single knot. Care should be taken to ensure that the tension-band wire and the proximal ends of the Kirschner wires are positioned deep to the triceps fibers to prevent wire migration. If the anterior cortex is engaged, overpenetration of the wires into the soft tissues should be avoided. Plate fixation is appropriate for severely comminuted fractures, distal fractures involving the coronoid process, oblique fractures distal to the midpoint of the trochlear notch, Monteggia fracture-dislocations of the elbow, and nonunions. For comminuted fractures and nonunions, a dorsally applied limited-contact dynamic-compression plate with supplemental bone graft should be utilized to support comminuted depressed articular fragments. A one-third tubular hook-plate can be used for fractures with a small proximal fragment for which additional fixation of the olecranon tip is desired. Fragment excision and triceps advancement is appropriate in selected cases in which open reduction seems unlikely to be successful, such as in osteoporotic elderly patients with severely comminuted fractures.
