Simultaneous chronic rupture of quadriceps tendon and contra-lateral patellar tendon in a patient affected by tertiary hyperparatiroidism
2007
Abstract Spontaneous ruptures of the extensor mechanism of the knee are very rare. They tend to increase considerably in patients with metabolic diseases such as chronic renal failure, hyperparathyroidism, diabetes, gout, and systemic lupus erythematosus. The reported case regards a 48-year-old man with chronic, spontaneous and simultaneous quadriceps, and contra-lateral patellar tendon rupture. The patient suffered from chronic renal failure and for the past year from tertiary hyperparathyroidism. Ruptured tendons were repaired and both knee were evaluated monthly for the next 12 months. Good functional recovery was achieved on both knees without relapse. This case emphasizes the importanc…
Total Elbow Replacement as Primary Treatment for Complex Fractures of the Distal Osteopenic Humerus
2003
Background: The use of hip and shoulder arthroplasty in elderly patients for grossly displaced intraarticular fractures is becoming more and more accepted. Total elbow replacement (TER) has not been considered an option for the treatment of extensively comminuted fractures of the distal humerus because surgeons feel the outcome is generally not predictable after TER. Evaluation of TER: On the basis of a MEDLINE literature search of this issue and the documented results based on the improvement of implant designs, operative technique and patient selection, TER has a definite role in the treatment of some fractures of the distal humerus.
Evaluation of efficacy and biocompatibility of a new absorbable synthetic substitute as a dural onlay graft in a large animal model.
2016
Numerous dura substitutes are commercially available, but no absorbable synthetic dura repair product has been used for both onlay and suture applications.The safety and effectiveness of a new absorbable synthetic substitute composed of Poly-L-lactide microfibers as onlay dural graft were evaluated.Physical properties and performance of the microfibrous synthetic dural substitute implanted as an onlay or suturable grafts were compared with these commercial products, including CODMAN ETHISORB™ Dura Patch and DuraGen™ Dural Graft Matrix, in a canine duraplasty model. The cerebrospinal fluid (CSF) leakage, macroscopic and microscopic observation at 30 and 90 days after implantation were invest…
Orbital Decompression for Endocrine Ophthalmopathy: The Endonasal Approach
1994
A surgical endonasal procedure is described to perform orbital decompression in patients suffering from ophthalmopathy in Grave's disease. The decompression technique employs removal of the lamina papyracea as an exclusive modality or in conjunction with a transmaxillary or lateral decompression approach. This present series contain 23 patients who underwent decompression over a 3-year period and were followed for at least 6 months postoperative. The results of decompression were assessed by measuring reduction in proptosis and visual acuity. All patients demonstrated improved visual acuity. Measuring retroplacement of the globe, the endonasal approach proved to equal the results obtained …
Das rachitische X-Bein im Kindesalter
2003
Knee malpositions, for example valgus or varus deformations or flexion contractures, were often cited in the historical literature. In earlier times, clinical pictures such as rickets were often the reason for this kind of deformity. A causal therapy did not exist until the twentieth century. In most cases of rickets, genu valgum was reported as the typical knee deformation. The differential diagnosis for genu valgum caused by rickets was genu valgum traumaticum, paralyticum, and inflammatorium. The most important reports on the pathogenesis of valgus deformation can be found in publications by Hueter and von Mikulicz. The causal therapy of rickets was introduced at the beginning of the twe…
Treatment of Combined Medial and Lateral Collateral Ligament Insufficiency
2016
The medial and lateral collateral ligament complexes represent primary elbow ligament stabilizers. Injury to these structures may occur because of an elbow dislocation or due to a severe varus or valgus force. Most elbow dislocations are stable once reduced and may be treated conservatively. However, if the elbow remains unstable surgical treatment is recommended. Repair should be anatomical and should restore stability to the elbow in order to permit an early active range of motion. Reconstruction may be required in severe cases and where primary repair is not possible. Depending on the degree of instability, either one or both of the collateral ligament complexes may need to be repaired o…
Post-synovectomy changes in the articular cartilage
1978
Synovectomy of the left knee was performed in 37 immature rabbits, using the right knee for control. In the first set of experiments the articular cartilage was examined at weekly intervals for 8 weeks following the operation, paying particular attention to the metachromatic changes in the ground substance of the cartilage. In the second set of experiments, restoration of synovium was examined. In the third and fourth set of experiments, the uptake of S35 by the cartilage was assessed using autoradiography and densitometry. In the fifth set of experiments, alterations in S35 uptake by the chondrocitic cells of the cartilage were studied by electron microscopy.
Waterjet dissection in pediatric cranioplasty
2010
Object Waterjet dissection has been shown to separate tissues of different resistance, with preservation of blood vessels. In cranioplasty, separation of subcutaneous tissue and dura mater is often difficult to achieve because the various tissue layers strongly adhere to each other after decompressive craniotomy. In the present study, the potential advantages and drawbacks of the waterjet technique in cranioplasty after craniectomy and duraplasty are addressed. Methods The waterjet effect on fresh human cadaveric dura mater specimens as well as on several dural repair patches was tested in vitro under standardized conditions, with waterjet pressures up to 80 bar. Subsequently, 8 pediatric …
Kinetic Analysis: A Sensitive Outcome Objective Measurement Method in Evaluating Lateral Patellar Instability
2011
There are many diagnostic clinical tests (e.g., apprehension patellar test or the moving patellar apprehension test), outcome measures (general health and knee scales [IKDC form, Kujala scale, Fulkerson scale, Lysholm knee scoring scale, Tegner activity level scale, short form-36]), and instrumented measurements of patellar mobility (static stability), to assess lateral patellar instability.7,10,15,16 However, according to Smith and colleagues,15 the sensitivity/specificity – reliability/validity of such tests and outcome tools remain unclear for this patient population. These authors conclude that further work is needed to assess the appropriateness of these tests and outcomes.15Moreover, …
Anterior dislocation in a total knee arthroplasty: A case report and literature review.
2015
Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.
