1/34. Irreducible Galeazzi fracture-dislocation due to an avulsion fracture of the fovea of the ulna.We report a rare case of Galeazzi fracture-dislocation with an irreducible distal radioulnar joint. The cause of the irreducibility was entrapment of a fragment avulsed from the fovea of the ulna. The patient was successfully treated with open reduction and internal fixation of the radius, ulnar styloid process and avulsed fracture at the fovea of the ulna.- - - - - - - - - - ranking = 1keywords = dislocation (Clic here for more details about this article) |
2/34. Synovial chondromatosis of the subcoracoid bursa.Synovial chondromatosis, is the chondroid metaplasia of the synovial membrane. Large joints such as the knee and hip are most commonly involved. Extraarticular involvement is rarely described. Synovial chondromatosis may be associated with impingement syndrome of the shoulder. We report a case of synovial chondromatosis of the subcoracoid bursa, which resulted in impingement symptoms.- - - - - - - - - - ranking = 0.02890995850421keywords = hip (Clic here for more details about this article) |
3/34. Femoral head disintegration in a paraplegic patient: loose bodies in neuropathic joints.A case report of potential loose body formation in a hip joint of a paraplegic patient is presented. The case is used to discuss why loose bodies do not persist in neuropathic joints, although they might be expected to be common when this type of joint pathology exists.- - - - - - - - - - ranking = 0.02890995850421keywords = hip (Clic here for more details about this article) |
4/34. Pseudotumoral osteochondromatosis of the hip in a soccer player.The authors present a case of pseudotumoral osteochondromatosis of the hip, interesting for its clinical and radiological features. They discuss the incidence of the sport in the pathogenesis of the loose bodies and the magnetic resonance findings.- - - - - - - - - - ranking = 0.14454979252105keywords = hip (Clic here for more details about this article) |
5/34. Irreducible acute anterior dislocation of the shoulder caused by interposed fragment of the anterior glenoid rim.Failure of manipulative reduction of acute anterior dislocation of the shoulder is extremely rare. A 55-year-old man dislocated his right shoulder when he fell heavily. Initial radiographs and computed tomographs demonstrated an anterior dislocation with fracture of the glenoid rim. Several attempts at closed reduction were unsuccessful. At the time of open reduction, the cause of failure was found to be interposition of a fragment of the anterior inferior glenoid rim in the joint. To prevent redislocation, the fragment was held in place by two Herbert mini bone screws after anatomic reduction, and the ruptured subscapularis was reattached to the lesser tuberosity. Two and a half months after surgery, the shoulder was stable with full range of motion. To the best of our knowledge, this is the first reported case of interposition of a fracture-fragment of the anterior inferior glenoid rim causing failure of reduction.- - - - - - - - - - ranking = 1.4keywords = dislocation (Clic here for more details about this article) |
6/34. A locked knee in extension: a complication of a degenerate knee with patella alta.We present a case of superior dislocation of the patella trapped by interlocked osteophytes. Unlike previous reports, in which the mechanism resulted from a blow to the inferior pole, it is postulated that increased load on the extensor mechanism, combined with patella alta and patellofemoral osteophytes, caused locking of the knee in extension.- - - - - - - - - - ranking = 0.2keywords = dislocation (Clic here for more details about this article) |
7/34. Condylar hyperplasia associated to synovial chondromatosis of the temporomandibular joint: a case report.Condylar hyperplasia is a slowly developing malformation of the mandible, with elongation of the mandibular neck, that generally results in facial asymmetry. Synovial chondromatosis is a benign chronic disorder characterized by the formation of multiple small nodules of hyaline cartilage as a result of metaplasia of the synovial connective tissue. It affects mostly the large joints, particularly the knee, hip, elbow and ankle. The temporomandibular joint (TMJ) is rarely affected. The case of a 42-year-old male with a history of left preauricular pain and swelling and deviation of the mandible to the left upon opening the mouth is presented. Computed tomography disclosed hyperplasia of the left condyle with loose radiopaque bodies within the joint cavity. The left TMJ was subject to open surgery, which included resection of four loose bodies and a remodeling condylectomy. The histopathological study confirmed the diagnosis of condylar hyperplasia and chondromatosis of the left TMJ.- - - - - - - - - - ranking = 0.02890995850421keywords = hip (Clic here for more details about this article) |
8/34. Irreducible dorsal dislocation of the proximal interphalangeal joint caused by an osteochondral fragment.We report two cases of irreducible dorsal dislocation of the proximal interphalangeal joint caused by interposition of a small osteochondral fragment that avulsed from the base of the middle phalanx with the volar plate and outstretched collateral ligament.- - - - - - - - - - ranking = 1keywords = dislocation (Clic here for more details about this article) |
9/34. Arthroscopic removal of a loose body osteophyte fragment after superior patellar dislocation with locked osteophytes.The authors report the case of a loose body from a fractured osteophyte after a superiorly dislocated patella with locked osteophytes. Few cases of superiorly dislocated patellae have been reported in the literature and no cases of osteophyte fracture fragments after locked osteophytes with subsequent arthroscopic loose body removal have been reported. The loose body was removed and the distal pole of the patella was debrided arthroscopically. This patient and the majority of previously reported cases, herein reviewed, had patella alta with pre-existing patellofemoral arthrosis. Patella alta in the face of patellofemoral arthrosis should be considered a risk factor for loose body formation. Therefore, recurrent superior patellar dislocation and locking osteophytes may be a relative indication for pre-emptive arthroscopic debridement of locked osteophytes.- - - - - - - - - - ranking = 1keywords = dislocation (Clic here for more details about this article) |
10/34. Primitive synovial chondromatosis of the hip joint.Primitive synovial chondromatosis of the hip is quite rare. Through the presentation of four new cases, the authors discuss the pathologic and clinical features of this disease and evaluate the performance of imaging studies, emphasizing the value of CT scan for confirmation of radiographic findings. The indication for surgical treatment is analyzed for each stage of the disease.- - - - - - - - - - ranking = 0.14454979252105keywords = hip (Clic here for more details about this article) |
