Computed tomography with multiplanar reformation and three-dimensional image reconstruction in the preoperative evaluation of adult hip disease.

Computed tomography (CT) with multiplanar reformation and three-dimensional (3D) image reconstruction was used pre-operatively to outline the bony morphological changes and femoral-acetabular relationships in 25 adult patients suffering from hip disease. Diagnoses included ischaemic necrosis of the femoral head, osteoarthritis, rheumatoid arthritis, calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, previous trauma and chronic dislocation. Polyethylene models of the femora and acetabula were constructed from three-dimensional contouring of CT data and compared with resected specimens in patients subjected to subsequent total hip arthroplasty. Information provided by this imaging technique was useful in both selecting and guiding the most appropriate surgical procedure and it was found that models depicted the actual bony contours with reasonable accuracy. CT combined with multiplanar reformation and 3D analysis may be the optimal pre-operative means of assessment of the diseased adult hip.

Isolated dislocation of the tarsal navicular: a case report.

Isolated dislocation of the tarsal navicular is a rare injury that is not mentioned in standard orthopedic textbooks and described only once in the English literature. Because of the rarity of this condition, the best means of treatment has not been established. A patient with this unusual dislocation was recently diagnosed and treated. Open reduction was eventually required, which was followed by the development of ischemic necrosis of the navicular.

A technique for multiplanar reformation and three-dimensional analysis of computed tomographic data: application to adult hip disease.

A commercially available system which is able to accept input from computed tomographic (CT) or magnetic resonance (MR) scanners was used preoperatively to generate multiplanar reformations (MPR) and three-dimensional (3D) images depicting the osseous morphologic alterations and femoral-acetabular relationships in 25 adult patients with a variety of hip diseases. Polyethylene surface representations of femora and acetabulae were constructed by the 3D-contouring of CT data and were then compared to resected specimens from patients who subsequently underwent total hip arthroplasty. Information provided by this imaging strategy was useful in both selecting and guiding the most appropriate surgical procedure, and the models depicted actual osseous contours with reasonable accuracy. The system employed has distinct advantages over other previously described 3D imaging strategies, which include a menu-driven user-friendly interface, data base access via reference images, 3D sectional analysis, and contour file editing for selective visualization of desired structures.

Computed tomography with multiplanar reformation and 3-dimensional image analysis in the preoperative evaluation of ischemic necrosis of the femoral head.

Computed tomography (CT) with multiplanar reformation and 3-dimensional image reconstruction were utilized preoperatively to assess the extent of infarction and collapse of the femoral head in 15 patients with ischemic necrosis. Polyethylene models of the diseased femoral heads were constructed from 3-dimensional contouring of CT data, and compared with resected specimens in patients who underwent subsequent total hip arthroplasty. Information provided by this imaging strategy was valuable in both the selection and the planning of the most appropriate surgical procedure, and models were found to represent resected head configurations with reasonable accuracy. CT combined with multiplanar reformation and 3-dimensional analysis may be the optimal preoperative means for evaluating advanced ischemic necrosis involving the femoral head.

Intracapsular pressure monitoring during arthrographic evaluation of painful hip prostheses.

Aspiration-arthrography with continuous monitoring of intraarticular pressure and volume was performed on 10 consecutive patients with painful total-hip arthroplasties. Five of these patients demonstrated clinical and arthrographic evidence of adhesive capsulitis, a condition that was associated with a dramatic rise of intraarticular pressure as increasing amounts of contrast material were introduced. The precise etiology of adhesive capsulitis is not clear.

Intra-articular pressure determination during glenohumeral joint arthrography. Preliminary investigation.

Utilizing cadaveric and patient shoulders, normal values of intra-articular pressure were established during injection of increasing volumes of fluid within the glenohumeral joint. The characteristic biphasic pressures vs. volume curve that was normally observed was then compared with curves obtained in patients with a tear of the rotator cuff or with adhesive capsulitis. This method of examination should allow accurate objective assessment of the presence and severity of adhesive capsulitis.
