Treatment of osteochondritis lesion in the knee with reduction and fixation under arthroscopy / 中国骨伤

<p><b>OBJECTIVE</b>To study clinical results of reduction and fixation under arthroscopy for the treatment of osteochondrotical lesion in the knee.</p><p><b>METHODS</b>From December 2012 to December 2013, 4 patients with the knee joint osteochondritis lesion and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the patients had swelling and effusion in the knee joint, and the floating patellar test was positive. CT examination showed bone defects and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation.</p><p><b>RESULTS</b>All the patients underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the patients were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one patient, arthroscopy examination was conducted for a second time to examine the connection of the fracture part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all patients were better than those before operation.</p><p><b>CONCLUSION</b>Treatment of osteochondritis lesion with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.</p>

AO clavicular hook plate for the treatment of fresh Tossy type III acromioclavicular joint dislocation in 28 patients / 中国骨伤

<p><b>OBJECTIVE</b>To investigate clinical results of AO clavicular hook plate for the treatment of fresh Tossy type III acromioclavicular joint dislocation.</p><p><b>METHODS</b>From December 2006 to December 2008, 28 patients with fresh Tossy type III acromioclavicular joint dislocation were treated with AO clavicular hook plates. There were 23 males and 5 females. The average age at surgery were 46.4 years (ranged, 22 to 68 years). The average time from suffering injuries to the operation was 3.9 days(ranged, 1 to 21 days). And the average time from the operation to plate removal was 9.4 months(ranged, 6 to 22 months).</p><p><b>RESULTS</b>All the patients were followed up, the duration ranged from 6 to 24 months, with an average of 15 months. There was 1 patient with traumatic arthritis, 1 patient with plate fracture. And the others had good results without fracture and re-dislocation after operation. According to Karlsson standards, 21 patients got an excellent result, 6 good and 1 poor. Eight patients had pain and restricted activities in shoulder joints before the plate removal, and all the symptoms were catabatic after removing the clavicular hook plates. After exercise, the function of the shoulder joints achieved normal level.</p><p><b>CONCLUSION</b>Clavicular hook plate used for the fresh Tossy type III acromioclavicular joint dislocation has advantages such as simple operation, little wound, less blood loss and early exercises.</p>
