Radial neck fracture fixation by Metaizeau technique in adults: A case series and review of literature

To evaluate the use of Metaizeau technique in the treatment of radial neck fracture in adults. A total of eight patients were treated with intramedullary pinning (Metaizeau technique) using titanium elastic nails. All the patients suffered isolated radial neck fracture. Fracture morphology in all the patients had angulation more than 30° and were displaced, tilted with the impacted articular fragment. All the patients had Mason's type III or Judet's type II or III fracture. The mean age of patients was 31.3 years, and all were operated within 7 days of suffering the injury. The mean follow-up was 9 months. For subjective evaluation, patients rated their satisfaction for elbow use on a scale of 1–6. Objective assessment includes Mayo elbow performance score, active range of motion of flexion and extension and forearm rotation. The active ranges of motion and hand grip strength were comparable in both upper limbs. Similarly, the range of flexion–extension and pronation–supination were identical. In all cases, the titanium elastic nails had already been removed after 8 weeks with osseous healing of the radial neck. Patients rated their satisfaction for elbow function as very good in six cases and good in two cases. In the present case series, the results of the use Metaizeau technique in adults were promising. The proper selection of the patient and timing of surgery should be considered judiciously. Further large case series is required to ascertain the results. Level IV. 評估Metaizeau技術在治療成人橈骨頸骨折中的應用。 共有8名患者使用鈦彈性髓內釘（Metaizeau技術）。 所有患者均經歷單獨的橈骨頸骨折。 所有患者的骨折形態均為成角超過30°、並且移位，與受壓緊的關節骨片傾斜。 所有患者均有梅森Ⅲ型或JudetⅡ型或Ⅲ型骨折。 患者的平均年齡為31.3歲，均在受傷後7天內進行手術。 平均隨訪時間為9個月。 對於主觀評估，患者評分滿意度為1-6分。 客觀評估包括梅奧肘關節評分、屈伸活動範圍和前臂旋轉。 雙側上肢的活動範圍和手握力都相當。 類似地，屈伸和旋前旋後的活動範圍是相同的。 在所有情況下，8週後鈦彈性釘已經被移除，並且橈骨頸骨性癒合。 患者對肘關節功能的滿意度在6例中表現非常良好，在2例中表現良好。 在目前的病例系列中，成人使用Metaizeau技術的結果大有可為。 適當地選擇患者和手術時機應慎重考慮。 需要進一步大型案例系列來確定結果。
