Dorsal plate assisted fixation of dorsal lunate fossa fracture of distal radius / 中国骨伤

OBJECTIVE@#To explore clinical efficacy of dorsal plate assisted fixation of dorsal lunate fossa fracture block of distal radius.@*METHODS@#From January 2019 to January 2022, 30 patients were treated with dorsal plate assisted fixation of dorsal lunate fossa fracture of distal radius, including 13 males and 17 females, aged from 42 to 68 years old with an average of (48.7±5.6) years old;According to Doi fracture classification, 24 patients were type 3 blocks and 6 patients were type 4 blocks. The degree of palmar angle of anterior and posterior distal radius was fixed by dorsal steel plate during operation. Fracture healing and functional recovery of wrist were observed after operation. Functional evaluation was performed by Gartland and Werley scoring system at 12 months after operation.@*RESULTS@#All patients were followed up from 12 to 13 months with an average of (11.3±0.9) months. All fractures healed for 4 to 5 months with an average of(4.7±0.8) months. Median palpal inclination of anterior and posterior distal radius fixed by dorsal plate was 5.30°(4.85°, 6.03°), 12.45°(11.98°, 13.43°) respectively, and had statistical difference( P<0.01). Gartland and Werley scores was (1.1±0.4) at 12 months afteropertaion, and 27 patients got excellent result and 3 good.@*CONCLUSION@#Dorsal plate assisted fixation of dorsal lunate fossa fractures is beneficial to reduction and stabilization of displaced dorsal fractures and restoration of palmar inclination.

Surgical treatment of ulnar lateral mass fractures of distal radius / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the type and corresponding operation methods of ulnar lateral mass in distal radial fractures.</p><p><b>METHODS</b>From January 2004 to September 2010,32 cases of distal radial fractures with ulnar lateral mass were treated by surgical incision and relocate ulnar lateral mass,including 23 males and 9 females with an average age of (34 +/- 9) years old ranging from 28 to 65 years old. According to the classification of Melone-Doi, 2 cases with type I, 24 cases of type II, 6 cases with type III. The operative appoach involved palm-radial, palm-ulnar, radial-dorsal. Among them, 28 patients with closed fractures were fixed with plate, 4 cases (including 2 cases of open fractures) were fixed by Kirschner pin and braces.</p><p><b>RESULTS</b>Thirty-two patients were followed up for 8 to 18 months with an average of 12 months. All fractures were healing without complications. According to modified Gartland-Werley scoring system (GWSS), the total score was 1.12 +/- 0.45, the remain deformity was 0, subjective evaluation was 0.50 +/- 0.30, objective evaluation was 0.30 +/- 0.21, complications was 0.40 +/- 0.09; the result was excellent in 21 cases, good in 11 cases.</p><p><b>CONCLUSION</b>The location of ulnar lateral mass in distal radial fractures is one of the important prognostic factors in wrist function and surgical treatment is an effective method of fixing ulnar lateral mass in distal radial fractures.</p>

Minimally invasive percutaneous plate osteosynthesis for the treatment of intertrochanteric femoral fractures of Evans IlI and IV in elderly patients / 中国骨伤

<p><b>OBJECTIVE</b>To study therapeutic effects of minimally invasive percutaneous plate osteosynthesis for the treatment of intertrochanteric femoral fractures of Evans III, IV in elderly patients.</p><p><b>METHODS</b>From December 2007 to April 2010, 23 patients with intertrochanteric femoral fractures were reviewed. Among the patients, 11 patients were male and 12 patients were female,ranging in age from 62 to 90 years, with a mean of 72.8 years. According to Evans classification, 13 patients were type III and 10 patients were type IV. All the patients were treated with proximal femoral locking plate (minimally invasive percutaneous plate osteosynthesis, MIPPO) surgery.</p><p><b>RESULTS</b>The operative time ranged from 45 to 60 min, with an average of 50 min. The blood loss ranged from 60 to 100 ml, averaged 80 ml. All the patients were followed up,and the duration ranged from 9 to 18 months, with an average of 11 months. The healing time based X-ray ranged from 3 to 6 months, with an average of 4 months. According to hip scoring criteria evaluation: 18 patients got an excellent results, 5 good.</p><p><b>CONCLUSION</b>For the treatment of intertrochanteric femoral fractures of Evans III, IV in elderly patients, MIPPO has advantages such as small trauma, reliable fixation, which has good clinical application.</p>
