Operative treatment of femoral neck fractures in patients between the ages of fifteen and fifty years

BACKGROUND: There is a paucity of data on the treatment of femoral neck fractures in young patients. The purpose of the present study was to review the results and complications associated with the treatment of femoral neck fractures with internal fixation in a large consecutive series of young patients. METHODS: Between 1975 and 2000, eighty-three femoral neck fractures in eighty-two consecutive patients who were between fifteen and fifty years old were treated with internal fixation at our institution. Two patients died, and eight were lost to follow-up. Seventy-three fractures were followed until union, until conversion to hip arthroplasty, or for a minimum of two years; the mean duration of follow-up was 6.6 years. Fifty-one of the seventy-three fractures were displaced, and twenty-two were nondisplaced. The results and complications of treatment were retrospectively reviewed, and the effects of fracture displacement, reduction quality, and capsular decompression on outcome were evaluated. Function was assessed by evaluating pain, walking capacity, and the need for gait aids. The mean duration of follow-up for the fifty-seven patients (fifty-eight fractures) who had not undergone early conversion to arthroplasty was 8.1 years. RESULTS: Fifty-three (73%) of the seventy-three fractures healed after one operation and were associated with no evidence of osteonecrosis of the femoral head. Osteonecrosis developed in association with seventeen fractures (23%), and a nonunion developed in association with six (8%). Four of the six nonunions later healed after a secondary procedure. At the time of the final follow-up, thirteen patients had had a conversion to a total hip arthroplasty because of osteonecrosis (eleven), nonunion (one), or both (one). Five (9.8%) of the fifty-one displaced fractures were associated with the development of nonunion, and fourteen (27%) were associated with the development of osteonecrosis. Three (14%) of the twenty-two nondisplaced fractures were associated with the development of osteonecrosis, and one (4.5%) was associated with the development of nonunion. Eleven (24%) of the forty-six displaced fractures with a good to excellent reduction were associated with the development of osteonecrosis, and two (4%) were associated with the development of nonunion. Four of the five displaced fractures with a fair or poor reduction were associated with the development of osteonecrosis, nonunion, or both. CONCLUSIONS: The ten-year survival rate of the native femoral head free of conversion to total hip arthroplasty was 85%. Osteonecrosis was the main reason for conversion to total hip arthroplasty, but not all patients with osteonecrosis required further surgery. The results of treatment were influenced by fracture displacement and the quality of reduction.

Operative management of displaced femoral neck fractures in elderly patients. An international survey

BACKGROUND: Hip fractures occur in 280,000 North Americans each year. Although surgeons have reached consensus with regard to the treatment of undisplaced fractures of the hip, the surgical treatment of displaced fractures remains controversial. Identifying surgeons' preferences in techniques, and the rationale for their choices, may aid in focusing educational activities to the orthopaedic community as well as planning future clinical trials. Our objective was to clarify current opinion with regard to the operative treatment of displaced fractures of the femoral neck. METHODS: We used a cross-sectional survey design and a sample-to-redundancy strategy to examine surgeons' preferences in the treatment of displaced femoral neck fractures. We mailed this survey to members of the Orthopaedic Trauma Association and European-AO International-affiliated trauma centers. RESULTS: Of 442 surgeons who received the questionnaire, 298 (67%) responded. The typical respondent was a North American man over the age of forty years who was in academic practice, supervised residents, had fellowship training in trauma, and worked in a low-volume center (<100 hip fractures per year), treating an equal proportion of displaced and undisplaced femoral neck fractures. Most surgeons believed that internal fixation was the procedure of choice in younger patients (those who are less than sixty years old) with a displaced fracture (Garden type III or IV). For patients over eighty years old with Garden type-III or IV fractures, almost all surgeons preferred arthroplasty. Respondents varied widely in their preferences for the treatment of patients who were sixty to eighty years old with a displaced fracture (Garden type III or IV) or active patients with a Garden type-III fracture. Many surgeons believed there was no difference between arthroplasty and internal fixation when considering mortality (45%), infection rates (30%), and quality of life (37%). Surgeons also revealed variable preferences in their choice of the optimal approach to arthroplasty for patients between sixty and eighty years old with a type-IV fracture (32% preferred unipolar; 41%, bipolar; and 17%, total hip arthroplasty) and in the optimal choice of implant for internal fixation. CONCLUSIONS: While surgeons prefer internal fixation for younger patients and arthroplasty for older patients, they disagree about the optimal approach to the management of patients between sixty and eighty years old with a displaced fracture and active patients with a Garden type-III fracture. Surgeons also disagree on the optimal implants for internal fixation or arthroplasty.     

Analysis of outcomes for surgically treated hip fractures in patients undergoing chronic hemodialysis

BACKGROUND: Hip fractures in patients with end-stage renal disease are associated with frequent complications. This study analyzed clinical outcomes for patients on chronic hemodialysis who sustained hip fractures and were treated with a variety of fracture repair methods. METHODS: Twenty-nine patients with thirty-two hip fractures were analyzed in three groups. Group 1 consisted of eleven hips in eleven patients with an intertrochanteric fracture that was treated with internal fixation; Group 2, thirteen hips in ten patients with a femoral neck fracture that was treated with screw fixation; and Group 3, eight hips in eight patients with a femoral neck fracture that was treated with hemiarthroplasty. The outcomes and early and late complications were recorded for each group. Survivorship analysis was performed, and the mortality and complication rates for the groups were compared. RESULTS: In Group 1, eight complications occurred in six hips and nonunion developed in five hips. In Group 2, sixteen complications developed in eleven hips. Union was achieved in two of the thirteen hips, nine hips had nonunion, and two hips had osteonecrosis develop. In Group 3, only one hip had early complications, there were no late complications, and three patients died. The mean duration of follow-up was twenty-three months, and the overall mortality rate was 45%. There were no significant differences among the groups with respect to the cumulative survival proportions. Regression analysis of age, sex, and total hemodialysis duration in relation to mortality risk revealed that only age had a significant influence on mortality (p = 0.019). CONCLUSIONS: Surgical treatment of hip fractures in patients with end-stage renal disease who are on chronic hemodialysis is associated with frequent complications and a high mortality rate. Osteosynthesis is an acceptable option for treating intertrochanteric fractures and nondisplaced femoral neck fractures, but displaced femoral neck fractures should be treated with hemiarthroplasty.     

Intertrochanteric osteotomy using a dynamic hip screw for femoral neck nonunion

The dynamic hip screw, which is routinely used for intertrochanteric hip fractures, also provides a technically simple means of fixation for intertrochanteric valgus osteotomies in the treatment of femoral neck nonunions. Eight patients underwent intertrochanteric valgus osteotomy for femoral neck nonunion using a dynamic hip screw for fixation. One patient died 4 months postoperatively of causes unrelated to the procedure. The remaining 7 patients were followed for an average of 24 months postoperatively. The nonunion healed in all 7 cases. The average angle of the fracture plane decreased from 68 degrees to 41 degrees. All the hip fractures were classified as Pauwels type III preoperatively and Pauwels type II postoperatively. The average Harris Hip Score increased from 24 to 73. On radiographic review, no cases of osteonecrosis were identified postoperatively.     

股骨干骨折合并同侧股骨颈骨折治疗的临床观察

目的：探讨股骨干合并同侧股骨颈骨折的治疗特点和不同固定方法的疗效。方法：股骨干骨折合并同侧股骨颈骨折27例,男22例,女5例;年龄14～65岁,平均35岁。动力髋螺钉（DHS）固定3例,加压钢板加空心加压螺钉固定12例,重建钉固定8例,顺行髓内钉加空心加压螺钉固定4例。13例固定术前用克氏针临时固定股骨颈骨折。结果：术后随访36～75个月,平均44个月。25例股骨颈骨折平均愈合时间4.5个月,2例股骨颈骨折不愈合。27例股骨干均愈合,平均愈合时间6个月。未用克氏针临时固定股骨颈骨折14例中,2例出现股骨颈不愈合,3例轻度髋内翻畸形。结论：股骨干合并同侧股骨颈骨折有许多固定方法可供选择,加压钢板加空心加压螺钉固定简便易用,在实施固定术前用克氏针临时固定股骨颈骨折可避免股骨颈骨折再移位和损伤。     

Failure of internal fixation of displaced femoral neck fractures in rheumatoid patients

We reviewed the records and radiographs from 10 hospitals to identify 50 patients with rheumatoid arthritis (RA) who had sustained 52 femoral neck fractures. Most patients were female (88%), elderly (mean age 66 years) and had had severe polyarticular disease for a mean duration of 16 years. Over half had taken systemic corticosteroids, nearly all were severely osteopenic but few had rheumatoid changes in the hip. Of the 20 fractures treated by internal fixation 12 had complications including nonunion (5), osteonecrosis (5), infection (1), and intertrochanteric fracture (1). Only one of the nine undisplaced fractures required reoperation, but seven of the 11 displaced fractures had revision surgery. Twenty fractures were treated by primary total hip arthroplasty with only one early complication. The other 12 fractures had been treated by hemiarthroplasty (9), hip excision (1) or non-operatively (2). Our results suggest that, in elderly rheumatoid patients, severely displaced femoral neck fractures should be treated by total hip replacement.
