1/16. Arthroscopic removal of bullet fragments from the subtalar joint.A case of arthroscopic removal of a bullet fragment from the subtalar joint and the calcaneus is presented. The bullet fragments impinged on the fibula, limiting eversion and causing pain. The fragments were removed both arthroscopically and through open incision. The patient noted complete relief of pain and improved range of motion within 1 week, and complete recovery soon thereafter.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/16. Aseptic synovitis after meniscal repair using the biodegradable meniscus arrow.We report a case of aseptic synovitis in a 19-year-old man. The synovitis of the left knee developed 13 months after meniscal repair using the biodegradable Meniscus Arrow (Bionx Inc, Malvern, PA). Histologic examination revealed chronic nonspecific synovitis and birefringent materials. Immunohistochemical tests were positive in lysozyme, alpha-1-antitrypsin, and alpha-1-antichymotrypsin. After arthroscopic synovectomy, pain and swelling of the knee joint were relieved and the patient's range of motion fully recovered. We have found no previous report of aseptic synovitis accompanying meniscal repair using the biodegradable Meniscus Arrow.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/16. Arthroscopic treatment of a transarticular low-velocity gunshot wound using tractoscopy.An unusual case of a close-range, low-velocity gunshot wound to the knee is presented. Arthroscopic debridement was accomplished using standard anterior portals as well as the existing entry and exit wounds. All bullet fragments were successfully removed from the joint by arthroscopy and tractoscopy. A minimally displaced marginal, lateral tibial plateau fracture was observed and treated with restricted weight bearing and active motion. The patient recovered uneventfully and maintained full knee range of motion and a normal gait.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
4/16. Delayed hemopericardium following penetrating foreign body into the aorta.A four and a half year old girl with delayed appearance of traumatic hemopericardium, detected radiologically despite misleading clinical manifestations, is presented. The presence of cardiomegaly and a needle in the right upper mediastinum on the chest roentgenogram and its partial motion together with diminished cardiac pulsations at fluoroscopy led to angiocardiography. The radiological demonstration of hemopericardium due to the needle penetrating the aortic root, enabled successful surgical intervention.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/16. Arthroscopically assisted replacement of dynamic hip screw for unrecognized joint penetration of lag screw through a new portal.nails penetrating into the hip joint after fixation of intertrochanteric fractures may account for one third of all treatment failures. Some authors recommend leaving the nail in the penetrated position until union is certain. However, if the lag screw is long enough penetrate the acetabular joint surface and cause severe pain and limited range of motion, a new shorter one should replace it. In this situation, direct visualization of the joint surface may not be possible, and fluoroscopy can be difficult to interpret. To our knowledge, this is the first case report of left intertrochanteric fracture with unrecognized joint penetration of the lag screw that was replaced by a new shorter one with arthroscopic assistance through a new portal of the screw canal. This case constitutes a unique and interesting application of hip arthroscopy.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/16. Arthroscopic removal of bullet fragments from the subacromial space of the shoulder.This article describes a case of arthroscopic removal of a bullet fragment from the subacromial space. The bullet tore the rotator cuff and imbedded itself on the inferior surface of the acromion, producing pain and impingement. The bullet was removed, and the rotator cuff repaired arthroscopically. The patient noted complete relief of pain and improved range of motion.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
7/16. Critical failure of a percutaneous discectomy probe requiring surgical removal during disc decompression.OBJECTIVE: We report a complication while performing a percutaneous disc decompression at the L4-L5 level using a Dekompressor Percutaneous Discectomy Probe. CASE REPORT: A 54-year-old male was referred to the pain clinic for possible percutaneous disc decompression. For the procedure the Dekompressor unit was inserted over the stylette and a percutaneous disc decompression was performed for 1 to 2 minutes using the channeling technique. Approximately (3/4) mL of disc nucleus was successfully removed. Upon withdrawal of the Dekompressor unit, it was noted that the probe was no longer connected to the device handle. Fluoroscopic imaging showed that approximately 4 inches of the probe remained in the patient and that the auger's distal end was still lodged in the disc. An incision was made, and the auger was successfully removed by a neurosurgeon. CONCLUSIONS: The patient had an uneventful recovery. Manipulation of the auger should be performed in a linear motion as best as possible and under fluoroscopic guidance.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
8/16. Radiolucent foreign bodies in the hand: case report.An unusual case of radiolucent foreign bodies (wood) in the hand is reported. diagnosis rests on clinical suspicion and is often suggested by the injury mechanism. Management includes antibiotics, x-rays and in some instances CT scan before exploration in selected cases; re-exploration in this case 12 days after the initial operation revealed another large piece of wood, which was successfully removed. Split-skin grafting was done 10 days later, and the patient was asymptomatic with full range of motion 5 weeks after that.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
9/16. Pantopaque mimicking spinal lipoma: MR pitfall.We present a patient with an intraspinal, high-signal-intensity lesion in the lumbosacral region on T1-weighted magnetic resonance images and a thin line of signal void between this region and the CSF on T2-weighted images. These findings were interpreted initially as representing an extradural spinal lipoma. However, CT revealed an intrathecal collection of iophendylate (Pantopaque), which was subsequently removed via a lumbar puncture. The apparent separation of Pantopaque from the CSF (seen on T2-weighted images and interpreted as the dura) was probably caused by chemical shift artifact, chemical shift contour, and/or CSF motion artifact.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
10/16. Hickman catheter tip displacement.In a series of 60 consecutive patients in whom Hickman catheters were placed for treatment of malignancy, four properly positioned catheter tips migrated secondarily from the superior vena cava to the ipsilateral jugular vein 2, 4, 21, and 25 days after placement. Three of the four patients had begun to have catheter dysfunction when the displacement was diagnosed. No satisfactory explanation for this rarely reported complication was evident in three of the cases. Maneuvers such as coughing, Valsalva's maneuver, and forceful heparin flushing produced no motion in three normally directed catheter tips in other patients observed under fluoroscopy. The phenomenon may be more common than previously reported. Evaluation of any new Hickman catheter dysfunction should include a chest x-ray film to ascertain the position of the catheter.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
