1/39. 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 = 1keywords = body (Clic here for more details about this article) |
2/39. Distinguishing multiple rice body formation in chronic subacromial-subdeltoid bursitis from synovial chondromatosis.Multiple rice body formation is a complication of chronic bursitis. Although it resembles synovial chondromatosis clinically and on imaging, the literature suggests that analysis of radiographic and MR appearances should allow discrimination. We report the imaging findings in a 41-year-old man presenting with rice body formation in chronic subacromial-subdeltoid bursitis. We found that the signal intensity of the rice bodies is helpful in making the diagnosis.- - - - - - - - - - ranking = 6keywords = body (Clic here for more details about this article) |
3/39. 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 = 3keywords = body (Clic here for more details about this article) |
4/39. 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 = 8keywords = body (Clic here for more details about this article) |
5/39. Biodegradable screw presents as a loose intra-articular body after anterior cruciate ligament reconstruction.We report a case of intra-articular movement of a broken piece of a poly-L-lactide (PLLA) bioabsorbable interference screw from the femoral tunnel in anterior cruciate ligament (ACL) reconstruction with quadrupled semi-tendinosus and gracilis tendon grafts. Eleven months after initially successful ACL surgery, the patient felt a sudden locking of the knee without associated trauma or injury. The patient experienced pain and swelling episodes after heavy lifting with knee flexion at work, but without symptoms of giving way or locking. On revision arthroscopy, a broken part of a bioabsorbable interference screw was seen in the lateral compartment, which was subsequently removed without incident. The semitendinosus-gracilis graft appeared intact without disruption. After revision surgery, the patient's recovery was uneventful, with return to activity within a few months. This case further shows the problem of biointerference screw breakage in ACL reconstructive surgery and the need to bury the femoral bioabsorbable interference screw on graft fixation.- - - - - - - - - - ranking = 4keywords = body (Clic here for more details about this article) |
6/39. Hip arthroscopy for osteochondral loose body removal after a posterior hip dislocation.We report on the application of hip arthroscopy to remove an osteochondral fragment created by a posterior hip dislocation. Preoperative and postoperative radiographs and computed tomography scans correlate with intraoperative arthroscopic photographs and are presented with this report. arthroscopy allowed excellent visualization of the joint and facilitated straightforward removal of the fragment. We were able to avoid the larger incision required by an arthrotomy and decreased the patient's overall morbidity from this condition.- - - - - - - - - - ranking = 4keywords = body (Clic here for more details about this article) |
7/39. Loose body in the wrist: diagnosis and treatment.PURPOSE: The purpose of this study was to report on 10 cases of symptomatic loose bodies in the wrist joints diagnosed using arthroscopy. TYPE OF STUDY: Retrospective review. methods: From 1986 to 2000, we performed wrist arthroscopy for 707 patients, 10 of whom had loose bodies in the wrist joints. The clinical records were reviewed retrospectively. The patients included 8 men and 2 women, and the average age was 28 years (range, 16 to 67 years). The chief complaint was wrist pain in all patients, but locking was uncommon. Preoperative diagnosis was difficult in all but 3 cases; in those cases, an osseous component was found within the loose bodies. The remaining cases were diagnosed by wrist arthroscopy. RESULTS: The loose bodies existed in the radiocarpal joint in 5 cases, and all could be removed arthroscopically. In the other 5 cases, the loose bodies were in the distal radioulnar joint, and arthrotomy was needed to remove them. After removal of the loose bodies, the pain was relieved in all cases without any surgical complications. CONCLUSIONS: Loose bodies in the wrist joint should be included in the differential diagnosis for chronic wrist pain. Wrist arthroscopy is of value because the preoperative diagnosis is usually difficult.- - - - - - - - - - ranking = 4keywords = body (Clic here for more details about this article) |
8/39. recurrence of synovial chondromatosis of the glenohumeral joint after arthroscopic treatment.A case of primary synovial chondromatosis of the shoulder in a 15-year-old girl is presented. Plain radiographs revealed findings characteristic of synovial chondromatosis. The patient was treated by arthroscopic loose body removal and arthroscopic partial synovectomy of the glenohumeral joint. Although immediate postoperative radiographs showed no calcification in the joint, repeated radiographs at 18 months after surgery revealed recurrence of calcification in the subacromial space. Arthroscopic removal of all loose bodies and partial synovectomy appears to be a good method of giving symptomatic relief and early return to work. However, late recurrence should be anticipated.- - - - - - - - - - ranking = 1keywords = body (Clic here for more details about this article) |
9/39. Multiple rice body formation in the subacromial-subdeltoid bursa and knee joint.Multiple rice body formation is an uncommon disorder which resembles synovial chondromatosis both radiologically and clinically. The clinical symptoms are usually non-specific. We report on a pathologically proven multiple rice body formation in both the left subacromial-subdeltoid bursa and knee joint in a 4-year-old girl.- - - - - - - - - - ranking = 6keywords = body (Clic here for more details about this article) |
10/39. Loose intra-articular body following anterior cruciate ligament reconstruction.We report a case of intra-articular fracture of a bioabsorbable fixation device from the femoral tunnel in an anterior cruciate ligament reconstruction using a bone-tendon-bone graft. Thirteen months after successful reconstruction surgery, the patient experienced episodes of locking and medial joint pain. There was no history of trauma and no symptoms of instability or swelling. On revision arthroscopy, a fractured tip of a bioabsorbable RIGIDfix cross pin (Mitek, Westwood, MA) was identified in the medial compartment of the knee. There was a broad area of chondral erosion affecting the medial femoral condyle and a small defect to the medial tibial plateau where the loose body had been lodged. The bone-tendon-bone graft was intact without disruption. After arthroscopy, the patient was symptom free for 3 weeks but then developed further symptoms of locking. magnetic resonance imaging showed another loose body within the knee. A repeat arthroscopy was performed 6 weeks after the earlier procedure and another piece of the polylactic acid RIGIDfix cross pin was removed, this time from the lateral gutter. This case raises concern about the potential for breakage and resultant loose body formation that may occur after bioabsorbable cross-pin fixation and, particularly, the associated chondral damage that can occur if early intervention is not conducted.- - - - - - - - - - ranking = 7keywords = body (Clic here for more details about this article) |
