桡骨头骨折的治疗

目的分析桡骨头骨折的治疗方法及其疗效.方法对1999-2004年收治的30例桡骨头骨折的患者,其中采用保守治疗（保守组）9例（均属MasonⅠ型）,切开复位内固定（固定组）15例（属MasonⅠ型1例,MasonⅡ型12例,MasonⅢ型2例）,桡骨头切除（切除组）6例（均属MasonⅢ型）,并对其功能进行评定.结果治疗后各组随访1.0～4.5年,平均2.8年.按Mayo肘关节功能评分评定：保守组的优良率为88.9%（8/9）,固定组优良率为86.7%（13/15）,切除组优良率为83.3%（5/6）.结论桡骨头骨折应尽量解剖复位,如难以通过内固定方法重建,则采用单纯桡骨头切除和韧带修复.     

桡骨头和桡骨颈骨折

桡骨头和桡骨颈骨折的生物力学研究日益受到重视。治疗上,近年来倡导对合适病人行切开复位内固定,Herbert钉内固定的近期疗效优于保守治疗和桡骨头切除术,Swonson假体的应用仍有较大争议。桡骨头-肱骨小头位摄片可提高桡骨头无移位骨折的诊断率。本文还介绍了各家分类的特点和合并症的处理。

Displaced Operable Radial Head Fractures

Background  Radial head fractures are common injuries occurring in conjunction with other injuries. We hypothesize that the associated injuries are under-diagnosed, under-treated and are under-estimated in terms of their relevance to the patients final functional outcome. We hypothesize a high correlation between the associated injuries and poor functional scores. Materials  Thirty-nine displaced radial head fractures were clinically, radiologically and functionally assessed at an average of 47 months postoperatively. Demographic data, case notes, and follow up data were statistically analyzed. Pearson’s correlation coefficient was performed for the associated injuries and final functional scores. Results  There were 21 type II and 18 type III radial head fractures. About 52% of Mason type II (11/21) and 94% of the Mason type III (17/18) had associated injuries. The average Mayo Elbow Performance Score for the Mason II fractures was 70 and for the Mason III was 55. There was a strong correlation between the number of associated injuries and functional scores. For Mason II injuries the Pearson correlation coefficient was r = −0.994, and for the Mason III group, r = −0.972. Conclusions  “Isolated radial head fractures” are rare. All displaced radial head fractures need thorough clinical and radiographic evaluation. The associated injuries are often unappreciated on initial diagnosis and are often under-treated. Associated injuries are strongly correlated with poor functional scores and therefore need to be addressed during surgery.     

Excision of the Radial Head for Closed Fracture

Two-thirds of 12 patients reviewed at least 13 years after excision of the radial head for closed fracture had a good or fair result; poor results followed a delay of more than 6 weeks before operation. Less than half the patients admitted to significant elbow symptoms, although all but one had radiographic degenerative changes. All the patients except one had measurable radiographic inferior radio-ulnar subluxation, which averaged 2.3 mm, but this gave symptoms in only one case. The majority of patients can expect an acceptable clinical result from this procedure provided that certain conditions are met.     

The Role of Surgical Hip Dislocation in the Treatment of Acetabular and Femoral Head Fractures

Abstract Background and Purpose: Surgical hip dislocation by trochanteric flip osteotomy facilitates access to acetabular and femoral head fractures. Furthermore, it allows evaluation of cartilage damage and vascularity of the femoral head. In this study the potential benefits of this procedure for improved fracture management and for prognostic assessment were investigated. Patients and Methods: From July 1997 to October 1999, 20 selected patients with displaced acetabular fractures (n = 12), femoral head fractures (n = 7), or combined injuries (n = 1) were included. Inclusion criteria for acetabular fractures were either displaced posterior wall fragments with cranial extension or complex acetabular fractures involving a displaced transverse fracture line. Open reduction and fixation of either complex acetabular fractures or femoral head fractures were carried out through Kocher-Langenbeck approach, trochanteric flip osteotomy, and complete surgical hip dislocation. Additionally, the extent of cartilage destruction and femoral head perfusion were assessed. Results: Anatomic reduction ( 1 mm displacement) of acetabular fractures was achieved in 69% of patients and good reduction ( 3 mm) in 31%. In patients with acetabular fractures, severe cartilage destruction of the acetabulum was found in 38% and of the femoral head in 15%, while patients with isolated femoral head fractures revealed severe cartilage damage of the femoral head in 57%. Arterial bleeding from the femoral head, tested by drilling, was observed in all patients. Secondary dislocation of the trochanteric osteotomy occurred in one patient and made refixation necessary. Patients were reexamined at least 2 years after intervention. 77% of patients with acetabular fractures and all patients with femoral head fractures showed good or excellent results after 32.6 ± 6.1 months according to the functional score of DAubigné & Postel. Conclusion: Surgical hip dislocation allows adequate reconstruction of complex acetabular and femoral head fractures and intraoperative evaluation of local cartilage damage and femoral head perfusion.
