The Treatment of Mason Type II Radial Head Fractures using Closed Reduction and K-wire Fixation

PURPOSE: To analyze the clinical results of the treatment of Mason type II radial head fractures using closed reduction and K-wire internal fixation under C-arm guide by radiologically and functionally. MATERIALS AND METHODS: Between March 2001 and October 2003, 7 patients with Mason type II radial head fracture were treated by closed reduction and internal fixation using K-wires under C-arm guide. The average age of the patients was 38 (5 to 57) years old, and average duration of follow up was 20 (5 to 36) months. At last follow up, we evaluated the radiological results and functional results by classifying excellent, good, fair and poor according to functional rating system of Broberg and Morrey. RESULTS: The range of motion of the elbow at last follow up, average flexion contracture was 1.4 (0 to 10) degrees, further average flexion was 146.4 (140 to 150) degrees, average supination was 74.2 (70 to 80) degrees and average pronation was 75 (70 to 80) degrees. In the functional results, 6 cases were excellent and 1 case was good. In the radiological evaluations, the average time of union was 5 (4 to 6) weeks after the operation and no serious complication was occurred in any cases. CONCLUSION: In the treatment of Mason type II radial head fracures, closed reduction and K-wire internal fixation under C-arm guide was an effective method of treatment with satisfactory results and no complications.

Internal fixation of the radius head fractures / 中华创伤骨科杂志

Objective To investigate the treatment of radi us head fracture through internal fi xation.Methods 42cases of radius head fracture trea ted with internal fixation were foll owed up.Mason classification and Broberg and Morrey criteria were use d to analyze the correlation between the results and the factors of fractu re type and method of fixation.Results42cases were followed up for a mean time of 25months.Evaluation was done according to Broberg and Morrey score systems.The function recovered we ll in 76%of the cases.The results of minor plate group were better than th ose of the screw(P=0.01)or K wire group(P=0.04).The results of Mason typeⅡwere better than those of the typeⅣ(P=0.03).Conclusion Treatment of radius head fracture with internal fixation will improve the elbow function and has better result for Mason typeⅡ.Fixation with minor plate is better than with screw or K wi re.[

Comparison between radial head resection and open reduction and internal fixation in clinical treatment of Mason type- Ⅲ comminuted fractures of radial head / 中华创伤骨科杂志

Objective To compare the clinical results of radial head resection with those of open reduction and internal fixation in treatment of Mason type- Ⅲ comminuted fracture of radial head. Methods 58 cases of Mason type- Ⅲ radial head fracture were treated in our department from January, 1983 to July, 2005. 28 cases had resection of the fractured redial head, while the other 30 cases had open reduction and internal fixation. The outcomes were assessed on the basis of pain, motion, strength, radiographic findings, and elbow functional rating score. Results The resection group had a mean follow- up of 5.5 years (2 to 6), while the internal fixation group had 10 years (3 to 13). The average pain VAS (visual analog scale) score was 18.7 (11 to 25) for the resection group and 23.5 (17 to 25) for the fixation group with a P value of 0.0023. The elbow extension averaged - 12.4? in the resection group and - 5.8? in the fixation group (P0.05) , but the decrease of elbow extension and forearm rotation differed statistically between the 2 groups (P
