Surgical treatment for Mayo II B comminuted fracture of the olecranon / 中国骨伤

<p><b>OBJECTIVE</b>To study clinical effects of surgery for the treatment of Mayo II B comminuted fracture in ulna olecranon.</p><p><b>METHODS</b>From May 2008 to March 2015, a total of 37 patients with Mayo II B comminuted fracture in ulua olecranon were treated, including 20 males and 17 females, ranging in age from 40 to 65 years old ,with an average of 53 years old. All the patients were treated with open reduction and internal fixation within 4 to 7 days after injuries. All the patients had pain and functional disorder uf elbow joint. The X-ray and CT examination showed ulna olecranon comminuted fracture of Mayo II B. Postoperative complications were observed ,and Broberg-Morrey criteria was used tu evaluate therapeutic effects.</p><p><b>RESULTS</b>All the patients were followed up ,and the duraiton ranged from 9 to 30 months ,with a mean of 15 months. Two patients had surface infection around incision ,and were healed by changing dressings. No other complications occurred such as needle slipping to stimulate skin ,screw loosening and wire broken. One patient had slight uneveness of joint surface without obvious functional disorder. According to Broberg-Morrey elbow fracture curative effect criteria, 11 paients got an excellent result, 24 good and 2 fair,and the total score was 87.0 ± 7.3.</p><p><b>CONCLUSION</b>For the Mayo II B comminuted fracture in ulna olecranon, preoperative preparation, intraoperative restoring of the articular surface smooth and reasonable internal fixation, and postoperative rehabilitation actively, can obtain satisfactory clinical effects.</p>

Operation for the treatment of radial head fracture with collapse of anterior articular surface / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.</p><p><b>METHODS</b>From March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.</p><p><b>RESULTS</b>All the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.</p><p><b>CONCLUSION</b>Radial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.</p>

Case-control study on percutaneous treatment of foot Jones fracture with cannulated screws / 中国骨伤

<p><b>OBJECTIVE</b>To compare clinical effects between plaster fixation and cannulated screw for the treatment of Jones fracture.</p><p><b>METHODS</b>From 2006 to 2010, 41 patients with Jones fractures were divided into 2 groups. In Group A, there were 14 males and 8 females, ranging in age from 21 to 62 years, with an average of (32.3 +/- 8.7) years; the course of disease ranged from 2 h to 3 d; the patients in Group A were treated with plaster fixation. In Group B, there were 9 males and 10 females, ranging in age from 24 to 59 years, with an average of (28.8 +/- 7.9) years; the course of disease ranged from 0.5 h to 2 d; the patients in Group B were treated with cannulated screw fixation. The patients in two groups were followed up from a long time and the long-term effects were studied.</p><p><b>RESULTS</b>All the 41 patients were followed up, from 3 months to 2.5 years, with a mean of 11.3 months. All the patients in both groups were healed. The patients in Group B got postoperative wound healing with A degree at the first stage without complications. In accordance with the Maryland Foot Score, the therapeutic effect in Group B was better than that of Group A. The healing time in Group B was shorter than that of Group A.</p><p><b>CONCLUSION</b>Percutaneous minimally invasive treatment with micro-cannulated screw is an ideal method for the treatment of the Jones fracture.</p>

Diagnosis and treatment of the coronal fracture of the femoral condyle / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the diagnosis and treatment of the coronal fracture of the femoral condyle.</p><p><b>METHODS</b>Seven patients with Hoffa fracture treated in our hospital in recent 7 years were enrolled in this study. Six patients were treated with surgical treatment, while one non-displaced fracture received conservative treatment. Fractures were reduced under direct vision and fixed with hollow lag screws. The knees were immobilized in extension with cast after operation, and flexion exercise was commenced 3 weeks later.</p><p><b>RESULTS</b>All the patients were followed up. According to Kumar functional assessment system,5 patients got excellent results, 1 good, and 1 fair.</p><p><b>CONCLUSION</b>Rigid internal fixation with hollow lag screw and extension plaster fixation is the excellent way to treat the coronal fracture of the femoral condyle.</p>
