1/17. 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 = 1keywords = motion (Clic here for more details about this article) |
2/17. Late bullet migration into the knee joint.A 25-year-old active-duty police officer was found to have an intra-articular foreign body on radiographic study of his left knee joint. He had a gunshot wound to the midthigh 54 months prior to the presentation of symptoms. The bullet was lodged in the soft tissue without involving neurovascular structures. The patient complained of limited range of motion of the joint and a "rattle" sensation of the knee. Arthroscopically, a deformed metallic foreign body was found and retrieved. There was no injury inside the joint related to the loose body. These findings were consistent with a migrating bullet from the midthigh to the knee joint. The patient recovered uneventfully and returned to work.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/17. Tear of an ossified rotator cuff of the shoulder. A case report.A 57-year-old man with an ossified rotator cuff with acute tears was treated by resecting the ruptured part, as well as the ossicles, and by repairing the massive cuff defect with Teflon felt. Six years after surgery, the pain had been completely relieved, and shoulder motion and muscle strength had been recovered.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/17. arthroscopy and microfracture technique in the treatment of osteochondritis dissecans of the humeral capitellum: report of three adolescent gymnasts.The aim of this paper is to report on three cases of symptomatic osteochondritis dissecans of the humeral capitellum in adolescent gymnasts, two females and one male. In all the cases arthroscopic surgery was performed. During arthroscopy, loose osteochondral fragments were removed, the defect was debrided and microfractures were performed. All the three patients regained the full range of motion of the affected elbow, and returned to the high-level gymnastics within a period of 5 months. At 12 months follow-up, all the three patients remained symptomless and were participating in high-level gymnastics. A combination of arthroscopy and the microfracture technique is a reliable method with excellent short-term results in the treatment of the osteochondritis dissecans of the elbow.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/17. shoulder rheumatoid arthritis associated with chondromatosis, treated by arthroscopy.We present a case of rheumatoid arthritis that affected the right shoulder and was associated with chondromatosis and multiple loose body formation. The arthritis was treated arthroscopically with satisfactory results after a follow-up period of 15 months. In our case, arthroscopic debridement and partial synovectomy not only relieved the pain but also improved the range of motion the night after surgery. The multiple loose bodies irritating the synovium and causing effusion, crepitus, and locking were also removed. One may need to change portals of the scope and suction cannula to remove loose bodies in different joint spaces. The subacromial space must be searched for loose bodies. Thorough cleaning, lavage, and synovectomy are important parts of this surgery. The continuous passive motion (CPM) machine in the immediate postoperative period was helpful.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
6/17. Intraarticular loose bodies in the adolescent hip: results of treatment of those recognized late.Seven cases of intraarticular loose bodies, previously unrecognized, were treated with surgical removal of the fragment. The presence of an intraarticular loose body was suspected because of persistent pain, restriction of hip joint motion, and asymmetric widening of the medial clear space on an anteroposterior (AP) pelvic roentgenogram. The diagnosis was established by computed tomography (CT) scan. Surgical removal should yield a good to excellent result, even when performed late, as long as osteonecrosis is not present at the time of operation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/17. Synovial chondromatosis of the temporomandibular joint: report of two cases.Two cases of synovial chondromatosis of the temporomandibular joint are reported. This condition is rare but benign, with only 36 cases reported in the literature to date. Symptoms include tenderness, swelling, and limited range of motion, with deviation to the affected side. diagnosis is made both from the clinical presentation and histologic examination. The etiology is thought to be cartilaginous foci within the synovial membrane that become detached and proliferate in the synovium as chondrocytes. Treatment includes removal of the "loose bodies" and possible resection of the synovial membrane, condyle, and disk.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
8/17. Arthroscopic treatment of steroid-induced osteonecrosis of the humeral head.shoulder arthroscopy was performed on a 52-year-old man for the treatment of steroid-induced osteonecrosis of the humeral head. The removal of loose bodies and joint debridement has successfully improved the patient's functional status through relief of pain, improved range of motion, and elimination of locking. This case suggests another use of arthroscopy in the treatment of shoulder pathology.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
9/17. Giant intraarticular loose bodies of the knee. Cases demonstrate spectrum of the lesion.Synovial chondromatosis is a well-known, well-described clinical and histopathologic entity. Occasionally, loose bodies in the knee joint can continue to grow and become large enough to impinge on joint motion. Extremely large synovial chondromata are relatively rare in the knee joint and have only been described in singular case reports in the orthopaedic literature. We describe two cases representing the spectrum of this disease process occurring in the popliteal fossa, simulating bony and/or soft tissue neoplasm. Case 1 demonstrates a large ossified chondroma, while Case 2 demonstrates a large chondroma without much calcification and with no ossification present. Because of the rarity of these lesions, preoperative staging studies, including CT scan, bone scan, and angiography, are usually warranted to help in the preoperative planning. Open biopsy with adequate tissue sampling is necessary to make an accurate histopathologic diagnosis. Once diagnosis is made, local excision for removal of the mechanical block to motion results in "cure"; local recurrence has not been noted.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
10/17. osteochondrosis of the temporomandibular joint presenting as an apparent parotid mass.A mass in the preauricular area usually indicates the presence of a neoplastic or inflammatory process within the parotid gland. osteochondrosis is an unusual disease process affecting large joints, particularly the knee. Rarely, the temporomandibular joint (TMJ) may be affected. The disease process involves the synovial lining of the TMJ and is commonly ascribed to a benign neoplastic process or metaplasia, although trauma and inflammation have also been implicated. This process can result in single or multiple loose cartilage bodies (joint mice) within the joint cavity. Symptoms are usually those of a mass in the preauricular area, or those of TMJ dysfunction (pain, dislocation, click, decreased range of motion). Physical findings are limited to presence of a mass in the pre-auricular parotid area with a paucity of other parotid findings. Treatment involves removal of the loose cartilage bodies from the TMJ and possibly the synovial lining, if it appears to be severely damaged.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
