1/9. Preiser's disease: arthroscopic treatment of avascular necrosis of the scaphoid.We report the case of a 50-year-old female patient with Preiser's disease (avascular necrosis of the scaphoid) who, after a 2-year history of wrist pain, underwent arthroscopic debridement of the necrotic scaphoid using a standard technique. Osteoarthritic changes of the articular cartilage, partial rupture of the scapholunate ligament, local synovitis, and loose fragments were documented. The patient reported significant improvement in pain relief and complete relief of mechanical symptoms at 31-month follow-up examination. Radiographs demonstrated no progression of collapse of the scaphoid or acceleration of degenerative changes in the wrist. arthroscopy in Preiser's disease allows direct visualization and assessment of the exact pathology of the radiocarpal and midcarpal joint and the scaphoid cartilage. Arthroscopic debridement of the necrotic scaphoid increased wrist functional range of motion, provided excellent pain relief, and improved health-related quality of life.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
2/9. Arthroscopically assisted core decompression of the proximal humerus for avascular necrosis.Abstract Core decompression has been described as an effective treatment for early stage avascular necrosis of the humeral head. This article describes the technique for arthroscopically assisted core decompression of the humeral head using a transtibial anterior cruciate ligament guide. This technique provides an advantage over the open procedure by avoiding soft-tissue stripping or damaging the biceps tendon or ascending branch of the anterior humeral circumflex artery, as well as providing accurate and safe placement of the core biopsy tract and the ability to address other intra-articular pathology.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
3/9. Dislocation of the distal tibiofibular joint.A case report of a patient with posterior dislocation of an intact fibula at the distal tibiofibular joint is presented. This rare injury is a variant of a Bosworth fracture, which is a posterior dislocation of the fibula usually accompanied by an oblique fibular fracture. The injury was initially treated by open reduction of the fibular dislocation, repair of avulsed lateral and deltoid ligaments, and placement of a syndesmotic screw. At one year postoperative, the patient has a poor result secondary to talar avascular necrosis and secondary degenerative ankle arthritis.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
4/9. Ulnar translation of scaphocapitate arthrodeses in Kienbock's disease--two case reports.The treatment of Kienbock's disease can be problematic. We report 2 cases of ulnar translation of the wrist after scaphocapitate arthrodesis with lunate excision for the treatment of advanced Kienbock's disease. The radioscaphocapitate ligament was intact in both cases.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
5/9. vibration disease of the capitate.There are four previous cases of isolated avascular necrosis of the capitate in the literature. This report describes a fifth, and the first to be associated with vibration. A paint sprayer presented with wrist pain, tenderness over the capitate and radiological changes of avascular necrosis of the capitate. Following mid-carpal arthrodesis, he returned to work. The role of trauma and a pre-existing ligamentous abnormality of the wrist in the aetiology of this condition is discussed.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
6/9. Avascular necrosis of the capitate and dorsal dorsi-flexion instability.A vascular necrosis of the proximal part of the capitate is very rare and usually is secondary to a fracture of the waist in association with a scaphoid fracture |
the naviculocapitate syndrome. A case is presented in which partial avascular necrosis of the capitate occurred in association with bilateral dorsal dorsi-flexion instability. The authors suggest that this phenomenon represents a form of the naviculocapitate syndrome in which ligamentous laxity altered the line of failure, thus sparing the scaphoid from fracture. |
7/9. A comparative study of the surgical procedures to treat advanced Kienbock's disease.We have treated a total of 16 cases of advanced Kienbock's disease, stage III and IV by Lichtman's classification, with triscaphe fusion, tendon ball replacement arthroplasty after excision of lunate, proximal row carpectomy as a salvage procedure and limited wrist fusion, since 1985. All cases were followed for minimal 16 months after each operation. Tendon ball replacement arthroplasty after excision of lunate could not prevent further carpal collapse with persistent chronic wrist pain. The triscaphe fusion or radio-lunate fusion induced a marked limited wrist motion later, and the triscaphe fusion alone was not fit for the treatment of advanced one because of progressive proximal migration of capitate and continuous wrist pain due to ligamentous carpal instability in follow-up. So we tried to simultaneously combine tendon ball replacement arthroplasty after excision of lunate with triscaphe fusion in far advanced Kienbock's disease, and their end results was favorable. Proximal row carpectomy could be done in far advanced Kienbock's disease with reasonably painless wrist motions. The overall end results of proximal row carpectomy are much better than any form of carpal arthrodesis. Conclusively the proper way to treat advanced Kienbock's disease seems to depend on the patient's age, their job and sex, and the stage of disease. And the cause of wrist pain in advanced Kienbock's disease seems due to ligamentous carpal instability rather than osteoarthritis on radio-lunate joint.- - - - - - - - - - ranking = 2keywords = ligament (Clic here for more details about this article) |
8/9. Radial neck osteolysis after annular ligament reconstruction. A case report.The treatment of the dislocated radial head in a late Monteggia lesion remains a matter of controversy. Annular ligament reconstruction using a strip of triceps tendon is a commonly used technique. Although most published series report good and excellent results, the overall complication rate of this procedure is not known. This study reports a 9-year-old boy who had avascular necrosis and bone resorption of the radial neck after a late annular ligament reconstruction using a sling of triceps tendon for a radial head dislocation that was not detected previously.- - - - - - - - - - ranking = 6keywords = ligament (Clic here for more details about this article) |
9/9. An intra-articular fracture-dislocation of the acromioclavicular joint.A hybrid acromioclavicular joint fracture-dislocation in which an intra-articular fracture of the distal clavicle coexisted with a coracoclavicular ligament injury is described. The proposed mechanism of injury is a fall on the point of the shoulder that simultaneously drives the scapula both anteriorly and inferiorly. Forced anterior scapular protraction caused a displaced horizontal plane fracture of the inferior half of the distal clavicle, which was separated from the remainder of the clavicle. The inferiorly acromioclavicular ligament was still attached to this distal clavicle fragment. The inferiorly directed force ruptured the coracoclavicular and superior acromioclavicular ligaments.- - - - - - - - - - ranking = 3keywords = ligament (Clic here for more details about this article) |
