Background:

The proximal femur nail antirotation (PFNA) is the recent addition to the growing list of intramedullary implants for trochanteric fracture fixation. The initial results in biomechanical and clinical studies have shown promise. We report our results of low velocity trochanteric fractures internally fixed by proximal femur nail antirotation.

Materials and Methods:

A prospective study was conducted to assess the results of 122 elderly patients with low velocity trochanteric fractures [39 – stable (AO; 31-A1) and 83 – unstable (AO; 31-A2 and A3)] treated with PFNA from December 2008 to April 2010. Followup functional and radiological assessments were done. Results obtained were compared between stable and unstable fracture patterns using statistical tools.

Results:

The mean followup was 21 months (12–28 months). 11 patients were lost in followup. Union was achieved in all but one patient. Varus collapse was seen in 14 patients and helical blade cut out in one patient. Stable and satisfactorily reduced fractures had a significantly better radiological outcome. Functional outcome measures were similar across fracture patterns. 65% of the patients returned to their preinjury status. The overall complication rate was also significantly higher in unstable fractures.

Conclusion:

Good results with relatively low complication rates can be achieved by PFNA in trochanteric fractures in the elderly. Attention to implant positioning, fracture reduction and a good learning curve is mandatory for successful outcomes.  相似文献

INTRODUCTION

Bilateral intertrochanteric femur fractures are relatively rare injuries. This study aims to present a case of a patient with simultaneous bilateral intertrochanteric femur fractures and femoral diaphyseal fractures and proximal tibial fracture with his twelve years follow-up.

PRESENTATION OF CASE

A 44-year-old man presented to emergency department after a motor vehicle accident. Bilateral intertrochanteric femur fractures (OTA classification – 31A.1.2) and bilateral femoral diaphyseal fractures (OTA classification – 32A.2) and nondisplaced right proximal tibial fracture (OTA classification – 41B.1) were determined in radiographs. Following closed reduction, fractures were fixed with intramedullary nails bilaterally. Proximal tibial fracture was fixed with cannulated screws following open reduction. At twelfth year follow-up he was able to do his daily activities with minimal limitation.

DISCUSSION

High energy traumas, stress fractures, systemic disorders (osteomalacia, chronic renal failure), steroid treatments, seizures and electric injuries are possible causes for bilateral hip factures. However bilateral femoral diaphyseal fractures are mostly due to high energy traumas. Long-term biphosphonate use may also cause bilateral fractures. Single-stage surgery should be performed in order to avoid secondary damages of surgical interventions. All fractures of our patient were fixed in a single session. This prevented further deterioration of patient''s status and made rehabilitation easy.

CONCLUSION

Careful evaluation of all systems should be performed in multi-trauma patients to find out concomitant injuries. Single staged surgical treatment may decrease morbidities.  相似文献

Background:

Reverse oblique trochanteric fracture of femur is a distinct fracture pattern. 95° Dynamic condylar screw (DCS) and proximal femoral nail (PFN) are currently the most commonly used implants for its fixation. This study aims to biomechanically compare the cutout resistance as well as modes of failure of DCS and PFN in reverse oblique trochanteric fractures.

Materials and Methods:

Sixteen freshly harvested cadaveric proximal femoral specimens were randomly assigned to three mean bone mineral density matched groups, eight of which were implanted with 95° DCS and the other eight with PFN. The constructs were made unstable to resemble a reverse oblique trochanteric fracture by removing a standard size posteromedial wedge. These constructs were subjected to computer controlled cyclic compressive loading with 200 kg at a frequency of 1 cycle/second (1 Hz) and end points of both the groups were analyzed.

Results:

The bending moment of the PFN group was approximately 50% less than that of the DCS group (P<0.0001). The PFN group resisted more number of cycles than the DCS group (P=0.03) and showed lesser number of component failures as compared with the DCS group (P=0.003).

Conclusions:

The PFN is biomechanically superior to DCS for the fixation of reverse oblique trochanteric fractures of femur.  相似文献

Background:

Ipsilateral fractures of the proximal femur and femoral shaft are extremely uncommon injuries which occur in young adults who sustain a high energy trauma. A variety of management modalities have been tried to treat this complex fracture pattern ranging from conservative approach to recently introduced reconstruction nails. All these approaches have their own difficulties. We studied the outcome of long proximal femoral nail (LPFN) in the management of concomitant ipsilateral fracture of the proximal femur and femoral shaft.

Materials and Methods:

We analysed the prospective data of 36 consecutive patients who had sustained a high energy trauma (30 closed fractures and 6 open shaft fractures) who had concomitant ipsilateral fractures of the femoral shaft associated with proximal femur fractures treated with LPFN between December 2005 and December 2011. The mean age was 39 years (range 28-64 years). Twenty nine males and seven females were enrolled for this study.

Results:

The patients were followed up at three, six, twelve, and eighteen months. The mean healing time for the neck fractures was 4.8 months and for the shaft fractures was 6.2 months. The greater trochanter was splintered and widened in two cases which eventually consolidated. Two patients had superficial infection, two patients had lateral migration of the screws with coxa vara which was due to severe osteoporosis detected during the followup. We had two cases of nonunion of shaft fracture and one case of nonunion of neck fracture. Two cases of avascular necrosis of femoral head were detected after 2 years of followup. No cases of implant failure were noted. Limb shortening of less than 2 cms was noted in four of our patients. The functional assessment system of Friedman and Wyman was used for evaluating the results. In our series 59.9% (n = 23) were rated as good, 30.6% (n = 11) as fair, and 5.5% (n = 2) as poor.

Conclusion:

Long PFN is a reliable option for concomitant ipsilateral diaphyseal and proximal femur fractures.  相似文献

Purpose

There is no consensus about the best option of internal fixation for unstable intertrochanteric fractures. The aim of the present study was to compare proximal femoral nail (PFN) with contralateral reverse distal femoral locking compression plate (reverse-DFLCP) in the management of unstable intertrochanteric fractures with compromised lateral wall.

Method

In a randomized controlled study, from November 2011 to October 2012, 40 patients with unstable intertrochanteric fractures with compromised lateral wall (AO 31A 2.2 to 3.3) had osteosynthesis by PFN (n = 20) or reverse-DFLCP (n = 20). Intra-operative variables compared were duration of surgery, blood loss during surgery, fluoroscopy time and surgeons perception of the surgery. Patients were followed up clinically for a minimum of one year. Functional outcome was assessed by Parker Palmer mobility score (PPMS), Harris hip score (HHS), and Short Form-12. Failure was defined as any condition which would necessitate revision surgery with change of implant.

Results

Duration of surgery (p = 0.022), blood loss during surgery (p = 0.008) and fluoroscopy time (p = 0.0001) were significantly less in the PFN group than in the reverse-DFLCP group. No significant difference was found in type of reduction, difficulty in reduction and surgeon’s perception of surgery. The PFN group had better functional outcome than the reverse-DFLCP group. HHS for the PFN group was 81.53 ± 13.21 and for the reverse-DFLCP group it was 68.43 ± 14.36 (p = 0.018). SF-12 physical (p = 0.002) and mental component (p = 0.007) scores in the PFN group was significantly better than in the reverse-DFLCP group. There was one failure in the PFN group as compared to six in the reverse-DFLCP group (p = 0.036).

Conclusion

Due to favourable intra-operative variables, better functional outcome and lower failure rates, we conclude that PFN is a better implant than reverse-DFLCP for intertrochanteric fractures with compromised lateral wall.Keyword: Unstable intertrochanteric fractures, Lateral wall, Proximal femoral nail, Reverse distal femoral locking compression plate  相似文献

Background:

Ender and Simon Weidner popularized the concept of closed condylocephlic nailing for intertrochanteric fractures in 1970. The clinical experience of authors revealed that Ender nailing alone cannot provide secure fixation in elderly patients with osteoporosis. Hence we conducted a study to evaluate the efficacy of a combined fixation procedure using Ender nails and a cannulated compression screw for intertrochanteric fractures.

Materials and Methods:

76 patients with intertrochanteric fractures were treated using intramedullary Ender nails and cannulated compression screw from January 2004 to December 2007. The mean age of the patients was 80 years (range 70-105 years).Using the Evan’s system of classification 49 were stable and 27 unstable fractures. Inclusion criteria was high risk elderly patients (age > 70 years) with intertrochanteric fracture. The exclusion criteria included patients with pressure sores over the trochanteric region. Many patients had pre-existing co-morbidities like diabetes mellitus, hypertension, COPD, ischemic heart disease, CVA and coronary artery bypass surgery. The two Ender nails of 4.5mm each were passed across the fracture site into the proximal neck. This was reinforced with a 6.5 mm cannulated compression screw passed from the sub trochanteric region, across the fracture into the head.

Results:

The mean follow-up was 14 months (range 9-19 months) Average time to fracture union was 10 weeks (range 6-16 weeks). The mean knee ROM was 130° (± 5°). There was no case of nail penetration into hip joint. In five cases with advanced osteoporosis there was minimal migration of Ender nails distally.

Conclusions:

The Ender nailing combined with compression screw fixation in cases of intertrochanteric fractures in high risk elderly patients could achieve reliable fracture stability with minimal complications.  相似文献

Background

Controversy persists concerning the preferred treatment of peritrochanteric femoral fractures. The purpose of the present study was to evaluate the mid-term outcomes of the newly developed implants - proximal femoral nail antirotation (PFNA) for the stabilisation of this type of fracture.

Methods

Between April 2006 and March 2008, 169 patients with peritrochanteric femoral fractures were treated with PFNA. As many as 26 patients were excluded from the study. According to the Orthopaedic Trauma Association (OTA) classification system, the remaining 143 fractures were classified as 19 cases of AO/OTA 31A1 fractures, 83 cases of 31A2 fractures, 28 cases of 31A3 fractures and 13 cases of 31A combined with proximal 32 fracture or separate proximal 32 fracture. The mean age of these patients was 67 years (range, 20-93 years). The operative time, the overall fluoroscopy time, the duration of hospitalisation and the surgical complications were noted. Patients were followed up for a mean of 21 months (range, 12-36 months). Functional outcomes were assessed according to the Harris hip scoring system.

Results

Fifteen patients (10%) required open reduction. The mean duration of surgery (from the beginning of close reduction to wound closure) was 72 min with a range between 45 and 170 min. The mean fluoroscopy time was 164 s with a range between 92 and 396 s. The mean time of hospital stay was 15 days. Postoperative X-rays showed a good or acceptable reduction in 134 cases (94%), and an ideal implant position in 131 cases (92%). There were 12 (8%) postoperative complications. All patients except one healed their fractures without any implant-specific complication (bending, breaking of the implant, cut out of the PFNA blade, femoral head penetration of the blade or ipsilateral fractures of the femoral shaft at the tip of the implant). The average time to bone healing was 16 weeks (range, 12-25 weeks). At the time of the latest follow-up, 106 patients (74%) were restored to their preoperative mobility. The mean Harris hip score was 84 points (range, 46-100 points). A total of 106 patients (74%) had an excellent or good outcome. According to the patients and/or their caregivers, outcome was described as satisfactory in 120(84%) of the 143 patients, and 36(90%) of the 40 patients, who were more than 80 years old.

Conclusion

The results suggest that PFNA is a very effective and safe method in the treatment of different patterns of peritrochanteric femoral fractures. The fixation is adequate to maintain reduction over time even in osteoporotic bones.  相似文献

Background and purpose

Internal fixation is a therapeutic mainstay for treatment of undisplaced femoral neck fractures and fractures without posterior comminution. The best treatment for unstable and comminuted fractures, however, remains controversial, especially in older patients. The present study was designed to assess the utility of the Intertan Nail® (IT) for stabilization of comminuted Pauwels type III fractures compared to dynamic hips screw (DHS).

Methods

Randomized on the basis of bone mineral density, 32 human femurs were assigned to four groups. Pauwels type III fractures were osteomized with a custom-made saw guide. In 16 specimens the posteromedial support was removed and all femurs were instrumented with an IT or a DHS. All constructs were tested with nondestructive axial loading to 700N, cyclical compression to 1,400N (10,000 cycles), and loading to failure. Outcome measures included number of survived cycles, mechanical stiffness, head displacement and load to failure.

Results

Postoperative mechanical stiffness and stiffness after cyclical loading were significantly reduced in all constructs regardless of the presence of a comminution defect (p = 0.02). Specimens stabilized with the IT had a lower construct displacement (IT, 8.5 ± 0.5 mm vs. DHS, 14.5 ± 2.2 mm; p = 0.007) and sustained higher failure loads (IT, 4929 ± 419 N vs. DHS, 3505 ± 453 N; p = 0.036) than the DHS constructs.

Interpretation

In comminuted Pauwels type III fractures, the fixation with the IT provided sufficient postoperative mechanical strength, comparable rate of femoral head displacement, and a similar tolerance of physiological loads compared to fractures without comminution. The absence of the posteromedial support in comminuted fractures tended to reduce the failure load regardless of the fixation method.  相似文献
