Internal fixation with AO distal humerus plates for the treatment of distal humeral fractures in elderly osteoporotic patients / 中国骨伤

<p><b>OBJECTIVE</b>To study the clinical effects of AO distal humerus plate (DHP) for the treatment of distal humeral fractures in elderly osteoporotic patients.</p><p><b>METHODS</b>From September 2008 to January 2010, 18 elderly osteoporotic patients with distal humeral fractures were treated with open reduction and internal fixation with DHP. There were 3 males and 15 females, ranging in age from 62 to 83 years (averaged, 71.4 years). According to AO classification, 1 patient was Type A2, 3 patients were Type A3; 2 patients were Type B1, 2 patients were Type B2; 3 patients were Type C1, 4 patients were Type C2, 3 patients were Type C3. The surgical approaches were either bilateral or via olecranon process of ulna. Early mobilization was initiated after surgery. Functional results were evaluated according to the Mayo elbow performance score (MEPS).</p><p><b>RESULTS</b>The average duration of follow-up was 14.6 months (ranged from 11 to 24 months). All the patients had a complete healing of their fractures. There was no infection, hardware failure or loss of reduction after the operations. The average Mayo elbow performance score (MEPS) was (92.2 +/- 9.6) (65 to 100 points), among which the score of pain was (42.5 +/- 5.8) (30 to 45 points), the score of motion range was (19.2 +/- 1.9) (15 to 20 points), the score of stability was (9.2 +/- 1.9) (5 to 10 points), and the score of function was (21.4 +/- 2.9) (15 to 25 points). According to MEPS, 11 patients got excellent results, 5 good and 2 fair.</p><p><b>CONCLUSION</b>Treatment of distal humeral fractures in elderly osteoporotic patients with AO distal humeral plates can obtain immediate stabilization which facilitates early mobilization of the elbow.</p>

Effective analysis of percutaneous reduction and Kirschner pin fixation for the treatment of intraarticular fractures of the calcaneus in children / 中国骨伤

<p><b>OBJECTIVE</b>To introduce and evaluate the clinical effects of percutaneous reduction and Kirschner pin fixation for the treatment of intraarticular fractures of the calcaneus in children.</p><p><b>METHODS</b>From March 2001 to February 2009,12 patients with intraarticular calcaneal fractures were treated by percutaneous reduction and Kirschner pin fixation (13 feet). There were 8 males and 4 females,ranging in age from 3 to 14,with an average of 8.7 years. According to Essex-Lopresti classification, among 5 feet were tongue fractures and 8 feet were compressed fractures. According to Sanders classification, 9 feet were type II and 4 feet were type III. The Biihler angle and Gissane angle of the calcaneus were obtained before and after operation. All patients were evaluated according to Maryland Foot Score.</p><p><b>RESULTS</b>All the patients were followed up for 16-71 months (means 35.9 months),and all the incisions were healed without complications and infection. The preoperative X-ray film showed that Böhler angle was (19.7+/-5.3) degrees, Gissane angle was (137.3+/-7.5) degrees. The postoperative X-ray film demonstrated that Böhler angle was (32.6+/-3.7) degrees, Gissane angle was (125.4+/-2.9) degrees. There was a significant difference between preoperative and postoperative (P<0.01). The average Maryland score was 96.3+/-2.4 (range, 92 to 100 points).</p><p><b>CONCLUSION</b>Percutaneous reduction and Kirschner pin fixation is an effective minimally invasive way to treat intraarticular fractures of the calcaneus in children, it has many advantages such as minimal invasion, reliable fixation and satisfactory effects.</p>

Treatment of meniscal injuries of knee joints by arthroscopy / 中国基层医药

Objective To assess the effectiveness of treatment of meniscal injuries of knee joints by arthroscopy.Methods 33 patients 35 joints were followed up and the parts,types and treatment under arthroscopy were analysed.Results 33 patients were followed up from six months to six years,the mean preoperative Lysholm score was 60.5 points,and the mean postoperative one was 86.7 points.Conclusion The advantage of treating meniscal injuries by arthroscopy was the result of correct examination and little wound of arthroscopy operation,and arthroscopic repair or partial menisectomy could effectively restore the function of the injured knee.

Post-traumatic osteolysis of the distal clavicle, pubis and ischium in 7 patients / 中华创伤杂志(英文版)

Post-traumatic osteolysis (PTOL) is a very rare disease occurring after acute trauma or repetitive micro-trauma, which is characterized by persistent pain in the injured site. In this study, we reported 7 patients, in whom osteolysis developed in the distal clavicle, pubis and ischium.
