内固定与假体置换治疗Mason Ⅲ型桡骨头骨折的比较研究

目的比较切开复位内固定术与双极桡骨头假体置换术治疗MasonⅢ型桡骨头骨折的疗效。方法对17例MasonⅢ型桡骨头骨折患者采用Tornier骨水泥柄、双极桡骨头假体进行置换,其中新鲜Ma- sonⅢ型骨折15例,陈旧性MasonⅢ型骨折2例。手术均采用肘关节后外侧入路,17例均行环状韧带修复。术后48 h开始关节逐步被动功能操练。另外8例MasonⅢ型桡骨头骨折患者采用肘后外侧入路切开复位空心钉与多枚克氏针内固定作为对照。结果假体置换组14例患者得到6～27个月(平均12．5个月)随访,按照Broberg和Morrey的肘关节功能评分标准进行评分：优9例,良4例,可1例,优良率为92．8%；3例出现异位骨化,下尺桡关节未见异常改变。8例MasonⅢ型桡骨头骨折内固定患者均得到10～21个月(平均14个月)随访,肘关节功能评分：良1例,可4例,差3例,优良率为12．5%。两组间优良率比较差异有极显著性意义(O＜0．01)。结论采用双极桡骨头假体置换的方法治疗MasonⅢ型桡骨头骨折比切开复位内固定的方法更有利于恢复肘关节的稳定、伸屈活动及前臂的旋转活动。

Open reduction and internal fixation of Mason type III radial head fractures with and without an associated elbow dislocation

PURPOSE: The purpose of this study was to evaluate the treatment of patients with Mason type III radial head fracture with and without elbow dislocation by open reduction with internal fixation, collateral ligament repair, and early mobilization. An additional purpose was to investigate whether there is any effect of elbow dislocation on the severity and functional outcome. METHODS: Twenty-five patients were treated with open reduction with internal fixation using low-profile miniplate and screws for comminuted fracture of the radial head. Eighteen fractures were Mason type III, and 7 fractures were Mason type III with elbow dislocation. There were 5 women and 20 men with a mean age of 34 years. The mean follow-up time was 27 months. Patients were reviewed for functional ability, physical examination, and radiographic assessment. RESULTS: The mean functional index in Mason type III fracture and Mason type III fracture with elbow dislocation was 87 for both groups. The mean range of motion at the elbow joint was calculated as 5 degrees extension to 136 degrees flexion for Mason type III and 7 degrees extension to 133 degrees flexion for Mason type III with elbow dislocation. The mean pronation and supination for all patients were 74 degrees and 67 degrees , respectively. CONCLUSIONS: Selected Mason III radial head fractures and fracture dislocations could be stabilized satisfactorily with internal fixation. Meticulous surgical technique, combined with rigid internal fixation, can allow early motion of the forearm and elbow after fixation of Mason type III radial head fractures with and without elbow dislocation and ligamentous injury. We believe there is still a role for prosthetic replacement in comminuted Mason III radial head fractures that cannot reliably be treated with open reduction and internal fixation. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.     

Open reduction and internal fixation of fractures of the radial head

BACKGROUND: The purpose of this retrospective study was to analyze the functional results following open reduction and internal fixation of fractures of the radial head and to determine which fracture patterns are most amenable to this treatment. METHODS: Fifty-six patients in whom an intra-articular fracture of the radial head had been treated with open reduction and internal fixation were evaluated at an average of forty-eight months after injury. Thirty patients had a Mason Type-2 (partial articular) fracture, and twenty-six had a Mason Type-3 (complete articular) fracture. Twenty-seven of the fifty-six fractures were associated with a fracture-dislocation of the forearm or elbow or an injury of the medial collateral ligament. Fifteen of the thirty Type-2 fractures were comminuted. Fourteen of the twenty-six Type-3 fractures consisted of more than three fragments, and twelve consisted of two or three fragments. The result at the final evaluation was judged to be unsatisfactory when there was early failure of fixation or nonunion requiring a second operation to excise the radial head, <100 degrees of forearm rotation, or a fair or poor rating according to the system of Broberg and Morrey. RESULTS: The result was unsatisfactory for four of the fifteen patients with a comminuted Mason Type-2 fracture of the radial head; all four fractures had been associated with a fracture-dislocation of the forearm or elbow, and all four patients recovered <100 degrees of forearm rotation. Thirteen of the fourteen patients with a Mason Type-3 comminuted fracture with more than three articular fragments had an unsatisfactory result. In contrast, all fifteen patients with an isolated, noncomminuted Type-2 fracture had a satisfactory result. Of the twelve patients with a Type-3 fracture that split the radial head into two or three simple fragments, none had early failure, one had nonunion, and all had an arc of forearm rotation of > or =100 degrees. CONCLUSIONS: Although current implants and techniques for internal fixation of small articular fractures have made it possible to repair most fractures of the radial head, our data suggest that open reduction and internal fixation is best reserved for minimally comminuted fractures with three or fewer articular fragments. Associated fracture-dislocation of the elbow or forearm may also compromise the long-term result of radial head repair, especially with regard to restoration of forearm rotation.

Reconstruction of Mason type-III and type-IV radial head fractures with a new fixation device: 23 patients followed 1-4 years

BACKGROUND: Treatment options in radial head fractures of Mason types III and IV range from open reduction and internal fixation (ORIF) to radial head resection with or without prosthetic replacement. PATIENTS: In a prospective study, the radiographic and clinical outcome was evaluated in 23 patients (age median 51 years) with 23 complex radial head fractures median 2 (1-4) years after ORIF using a new fixation device (FFS; Orthofix). 14 Mason type-III fractures with 2 concomitant olecranon fractures and 1 ulnar nerve lesion, and 11 type-IV fractures with 2 olecranon fractures and 2 fractures of the coronoid process were treated. 2 patients were lost to follow-up. In 7 cases of joint instability, an elbow fixator with motion capacity was applied after ORIF of the radial head. RESULTS: No radial head resection was necessary. No secondary dislocations or nonunion occurred. The Morrey elbow score was excellent in 8 and good in 4 Mason type-III fractures and excellent in 5, good in 3, and fair in 3 Mason type-IV fractures. INTERPRETATION: Reconstruction of comminuted radial head fractures can be performed with this device and radial head resection can be avoided.

Newly defined fracture pattern specific to Mason III radial head fractures: fracture description, management and outcomes using screw fixation

Background: Radial head fractures are the most common type of elbow fracture and are universally classified under the Mason classification system. Mason type III fractures are comminuted and are the most difficult to treat, generally requiring plating if possible, or more commonly arthroplasty or excision, which gives a variable outcome. We hypothesized that a new and specific fracture pattern of the radial head (Mason III) can be treated successfully with screw fixation. Methods: Six patients presented to the senior surgeon's clinic with this unusual Mason III fracture pattern. In these patients, the fracture was acute, requiring an open reduction and internal fixation with the use of three headless compression screws. Average follow‐up time was 21 months. Using serial X‐rays and the Broberg–Morrey elbow score, the six acute fractures were evaluated radiologically and functionally. Results: All six patients had good to excellent results using the Broberg–Morrey scoring system. All patients showed radiological and clinical union within 3 months of injury. No patient required revision surgery or excision at a later date. Discussion: We have recognized a specific type of comminuted and displaced Mason III radial head fracture that has not previously been described in the literature. This type of fracture is amenable to open reduction internal fixation with buried compression screws giving a good to excellent outcome, while avoiding the common consequences seen with a radial head excision, arthroplasty or plate fixation.
