  • EFFECTIVENESS COMPARISON OF PROXIMAL FEMORAL NAIL ANTIROTATION AND DYNAMIC HIP SCREW FOR INTERTROCHANTERIC FRACTURES IN THE ELDERLY PATIENTS

    Objective To compare the effectiveness of the proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) in the treatment of elderly patients with intertrochanteric fractures. Methods Between May 2007 and May 2010, 63 elderly patients with intertrochanteric fractures were treated, and fractures were fixed with PFNA in 31 patients (PFNA group) and with DHS in 32 patients (DHS group). There was no significant difference in gender, age, injury cause, disease duration, and fracture type between 2 groups (P gt; 0.05). Results All incisions healed by first intention. The incision length, operation time, and blood loss in PFNA group were significantly less than those in DHS group (P lt; 0.05). The averagefollow-up time was 13.6 months in PFNA group and was 13.8 months in DHS group. The fracture heal ing time was (11.80 ± 1.32) weeks in PFNA group and was (12.21 ± 1.26) weeks in DHS group, showing no significant difference (t=1.23, P=0.29). The complication rate was 0 in PFNA group and was 12.5% (4/32) in DHS group, showing no significant difference (P=0.06). After 1 year, Harris hip score of PFNA group (86.55 ± 10.32) was higher than that of DHS group (80.36 ±11.18) (t=2.28, P=0.03). Conclusion There are two surgical methods to treat intertrochanteric fractures in the elderly patient: PFNA and DHS, and each has advantages; for unstable intertrochanteric fractures, PFNA treatment is the first choice.

  • COMPARISON OF PROXIMAL FEMORAL NAIL ANTIROTATION AND RECONSTRUCTION NAIL FOR IPSILATERAL FRACTURES OF HIP AND FEMORAL SHAFT

    Objective To compare the effectiveness of proximal femoral nail antirotation (PFNA) and reconstruction nail with minimally invasive technique for ipsilateral femoral shaft and extracapsular hip fractures in young and middle-aged patients. Methods Sixty-nine young and middle-aged patients with ipsilateral femoral shaft and extracapsular hip fractures were treated between January 2000 and August 2010, and their data were analyzed retrospectively. Of them, fractures were fixed by reconstruction nail in 44 cases (reconstruction nail group) and by PFNA in 25 cases (PFNA group). There was no significant difference in gender, age, weight, injury cause, fracture type, or disease duration between 2 groups (P gt; 0.05). The operation time, blood loss, fracture healing time, complications, and functional outcomes were compared between 2 groups to evaluate the effectiveness. Results The operation time and blood loss in the PFNA group were significantly less than those in the reconstruction nail group (P lt; 0.05). The follow-up time was 12-38 months (mean, 20 months ) in the PFNA group and was 12-48 months (mean, 22 months) in the reconstruction nail group. No complication occurred as follows in 2 groups: wound infection, deep venous thrombosis, pulmonary embolism, breakage of the implants, avascular necrosis of the femoral head, or serious rotation and shortening deformity of lower limbs. In the PFNA group and the reconstruction nail group, 1 patient underwent technical difficulty in nail implant and 7 patients underwent technical difficulty in proximal locking screw, respectively; 3 patients and 6 patients had intra-operative iatrogenic fracture of femoral shaft, respectively; and delayed union of femoral shaft was observed in 1 patient and 2 patients, respectively. The complication rate was 20% (5/25) in the PFNA group and 34% (15/44) in the reconstruction nail group, showing no significant difference (χ2=1.538, P=0.215). No significant difference was found in fracture healing time between 2 groups (P gt; 0.05). At last follow-up, there was no significant difference in Harris hip score and Evanich knee score between 2 groups (P gt; 0.05). Conclusion PFNA or reconstruction nail with minimally invasive technique is a good method to treat ipsilateral femoral shaft and extracapsular hip fractures, but the PFNA is superior to the reconstruction nail because of simple operation.

  • EVALUATION ON CURATIVE EFFECT OF THREE OPERATIVE METHODS IN TREATMENT OF SENILE INTERTROCHANTERIC FRACTURE

    Objective To analyze the cl inical appl ication and effect of three operation methods in treatment of senile intertrochanteric fracture. Methods From July 2004 to February 2007, 73 patients with intertrochanteric fracture were treated. Of 73 patients, 33 patients were treated by artificial bipolar femoral head (ABFH group), 18 patients by dynamic hip screw (DHS group) and 22 by proximal femoral nail anti-rotation (PFNA group). In ABFH group, there were 19 males and 14 females with age of (72.5 ± 3.8) years. The injury was by tumbl ing in 19 cases, by accident traffic in 7 cases, fall ing from height in 4 cases and others in 3 cases, including 6 cases of type I, 9 cases of type II, 11 cases of type III and 7 cases of type IV accordingto Evans classification. The Harris hip score was 16.8 ± 4.8, and the disease course was (21.2 ± 7.8) hours. In DHS group, there were 10 males and 8 females with age of (69.5 ± 3.2) years. The injury was by tumbl ing in 11 cases, by accident traffic in 5 cases, fall ing from height in 1 case and other in 1 case, including 6 cases of type I, 3 cases of type II, 5 cases of type III and 4 cases of type IV according to Evans classification. The Harris hip score of was 18.6 ± 5.5, and the disease course was (19.8 ± 6.5) hours. In PFNA group, there were 13 males and 9 females with age of (70.3 ± 3.5) years. The injury was by tumbl ing in 11 cases, by accident traffic in 6 cases, fall ing from height in 3 cases and others in 2 cases, including 5 cases of type I, 6 cases of type II, 6 cases of type III and 5 cases of type IV according to Evans classification. The Harris hip score was 20.4 ± 6.6, and the disease course was (20.0 ± 5.8) hours. All fractures were fresh. There were no significant difference in general data between three groups (P gt; 0.05). Results In ABFH group, all incisions healed by first intention, but deep vein thrombosis occurred in 1 case on the postoperative third day. In DHS group, incisions healed by first intention in 16 cases and by second intention in 2 cases, coxa adducta occurred in 2 cases after operation. In PFNA group, all incisions healed by first intention. Cacothesis in pate occurred in 1 case after operation. There were significant differences in operation time, blood loss, and out-of-bed time (P lt; 0.05). The patients were followed up (30.5 ± 6.5) months in ABFH group, (27.6 ± 6.2) months in DHS group, and (24.8 ± 5.4) months inPFNA group. The union time of fracture was (7.5 ± 2.5) months in ABFH group, (8.4 ± 2.2) months in DHS group and (7.2 ± 2.4) months in PFNA group. There were significant differences in Harris score between before operation and after operation and between different time after operation in three groups (P lt; 0.05). Conculsion The three operative methods have some their superiority, but the replacement of artificial bipolar femoral head is more suitable for the senile unstable intertrochanteric fracture because of simply procedure, short operation time, less blood loss and early ambulation.

    Objective To investigate the operative method and to evaluate the cl inical outcome of proximal femoral nail antirotation (PFNA) in treating reverse obl ique fractures of intertrochanteric region of the femur. Methods From January 2007 to February 2008, 30 cases of reverse obl ique fractures of intertrochanteric region of the femur were treated by closed reduction and fixation with PFNA, including 14 males and 16 females and aging 40-88 years old with an average of 68.6years old. All patients had closed fractures. According to AO classification, there were 6 cases of 31-A3.1 type, 7 cases of 31-A3.2 type and 17 cases of 31-A3.3 types. The time from injury to operation was 2-14 days (with an average of 5.3 days). All 31-A3.1 and 31-A3.2 type farctures and 9 cases of AO 31-A3.3 type fractures were fixed with the standard PFNA, and 8 cases of 31-A3.3 type fractures with the PFNA-long. The cl inical and radiological examinations were done at 1, 2, 3, 6, 12, and 18 months after operation. The cl inical outcomes were evaluated according to the Sanders scoring. Results Iatrogenic fracture of femoral shaft occurred in 1 case; no additional procedures were appl ied as fracture kept favorable stabil ity. Superficial infection occurred in 1 case at 5 days after operation, wound healed after dressing change and intravenous antibiotic therapy. Other wounds healed by first intention. All cases were followed up for 12-19 months (mean 14.1 months). All fractures healed uneventfully after 12-30 weeks (mean 16.2 weeks). Five patients complained of hip pain, 2 patients had lateral leg pain, and the pain was el iminated after symptomatic treatment. One case compl icated by ipsilateral fracture of the tibial plateau had functional disturbance of knee, and one case compl icated by ipsilateral fracture of the acetabulum and pelvis had functional disturbance of hip, and the function was improved after functional exercise. No compl ications such as cut-out or breakage of the implants occurred. According to Sanders criteria, the cl inical results were excellent in 22 cases, good in 6 cases, and poor in 2 cases. The excellent and good rate was 93.3%. Conclusion PFNA is an effective treatment method for reverse obl ique fractures of intertrochanteric region of the femur, with a high rate of bone union, minor soft tissue damage, early functional exercise and acceptable compl icationrelated to implant.

  • Comparison of the Therapeutic Effect of Intramedullary Fixation and Medullary External Fixation on Evans-Jensen Type Ⅲ Intertrochanteric Fracture

    ObjectiveTo compare the therapeutic effect between intramedullary fixation and external fixation on intertrochanteric fracture. MethodsBetween June 2005 and June 2011, 32 patients with Evans-Jensen type Ⅲ intertrochanteric fracture were treated with proximal femoral nail anti-rotation (PFNA), Gamma nail, dynamic hip screw plate (DHS) or locking compression plate (LCP), separately. The operation duration, peri-operative bleeding, load time, Harris hip score and postoperative complications were observed in the patients, and were used to analyze the therapeutic effect among the four methods. ResultsShorter operation duration, less bleeding in the surgery, smaller quantity of drainage after the operation (P<0.05) were found in group Gamma and group PFNA compared with those in group DHS and LCP. The duration of hospitalization didn't differ much between the two fixation systems (P>0.05). The difference in operation duration, operative bleeding and post-operative drainage between group Gamma and PFNA, and between group DHS and LCP was not significant (P>0.05). ConclusionThe intramedullary fixation was better than external fixation for Evans-Jensen type Ⅲ intertrochanteric fracture.

  • Contrast between the Curative Effect of Proximal Femoral Nail Antirotation and Locking Proximal Femoral Plate for Femoral Intertrochanteric Fracture in Senile Patients

    ObjectiveTo compare the clinical effect of proximal femoral nail antirotation (PFNA) and locking proximal femoral plate (LPFP) for femoral intertrochanteric fracture in elderly patients. MethodsWe respectively analyzed the clinical data of 116 senile patients with femoral intertrochanteric fracture treated between October 2008 and March 2014. Among them, 60 were treated with PFNA, and 56 were treated with LPFP. We compared the two groups of patients in terms of operating time, surgical blood loss, surgical complications, walking exercise time, fracture healing time and joint function recovery. ResultsA total of 115 patients had regular follow-up from 12 to 24 months (averaging 15.7 months). One patient died. The operating time was (83.26±14.81) minutes in PFNA group and (102.58±15.31) minutes in LPFP group. The surgical blood loss was (202.16±33.14) mL in PFNA group and (255.80±45.92) mL in LPFP group. The walking exercise time was (1.80±0.91) weeks in PFNA group and (3.48±3.03) weeks in LPFP group. The fracture healing time was (11.80±2.26) weeks in PFNA group and (12.14±2.21) weeks in LPFP group. The postoperative Harris score for hip joint was 84.56±9.55 in PFNA group and 82.47±9.22 in LPFP group. There were statistical differences in operating time, surgical blood loss and walking exercise time (P<0.05), while no statistical differences were found in fracture healing time and postoperative Harris score for hip joint (P>0.05). ConclusionPFNA and LPFP are effective methods for femoral intertrochanteric fracture in elderly people, but PFNA has a shorter operating time, less surgical blood loss and earlier walking exercise time.

  • MEASURING METHOD OF TIP-APEX DISTANCE IN TREATMENT OF FEMORAL INTERTROCHANTERIC FRACTURE WITH PROXIMAL FEMORAL NAIL ANTIROTATION

    ObjectiveTo investigate the method to measure the tip-apex distance (TAD) in treatment of femoral intertrochanteric fracture with proximal femoral nail antirotation (PFNA). MethodsBetween March 2008 and March 2011, 35 patients with femoral intertrochanteric fracture underwent closed reduction and internal fixation with PFNA, which were all closed fractures. There were 14 males and 21 females with an average age of 72.3 years (range, 48-88 years). According to Evans classification, 1 case belonged to type III, 27 cases to type IV, and 7 cases to type V. The time between injury and operation was 2-7 days (mean, 4.3 days). The TAD was measured according to relationship between tip of helical blade and the center point of femoral head radius during operation, and according to X-ray films after operation. ResultsPrimary healing of incision was obtained in all cases, and no infection or deep venous thrombosis occurred. At 2 days after operation, the X-ray films showed TAD was 18-24 mm (mean, 22.6 mm). Thirty-two cases were followed up 10-22 months (mean, 16 months). All fractures healed, with a mean healing time of 7.6 months (range, 6-10 months). The patients could walk without stick at 11-16 weeks (mean, 13 weeks). Pulmonary infection occurred in 1 case at 5 days after operation; no breakage of femoral nail or cut-out helical blade from femoral head was observed. At 10 months after operation, the Parker hip scores were 9 in 23 cases, 8 in 4 cases, 7 in 3 cases, and 5 in 2 cases, with a mean score of 8.44. ConclusionIt is easy to control the TAD in treatment of femoral intertrochanteric fracture with PFNA with an simple method and important to prevent breakage and cut-out helical blade from the femoral head.

  • EFFECTIVENESS COMPARISON OF PROXIMAL FEMORAL NAIL ANTI-ROTATION AND LOCKING COMPRESSION PLATE FOR INTERTROCHANTERIC FRACTURES WITH LATERAL UNSUBSTANTIAL FEMORAL WALL IN ELDERLY PATIENTS

    Objective To compare the effectiveness of the proximal femoral nail anti-rotation (PFNA) and locking compression plate (LCP) in the treatment of intertrochanteric fractures with the lateral unsubstantial femoral wall in elderly patients. Methods Between May 2009 and August 2012, 69 elderly patients with intertrochanteric fractures with the lateral unsubstantial femoral wall were treated. Fractures were fixed with PFNA in 36 patients (PFNA group), and with LCP in 33 patients (LCP group). There was no significant difference in gender, age, injury cause, side of fracture, and fracture AO type between 2 groups (P > 0.05). The incision length, operation time, intraoperative blood loss, total blood loss, fluoroscopy frequency, time for ambulation, and early (within 3 months) and late (more than 12 months) complications were compared. Fracture healing was assessed according to X-ray reexamination, the function of the hip joint was assessed according to the Harris hip scoring system. Results The incision length, operation time, intraoperative blood loss, and time for ambulation of PFNA group were significantly less than those of LCP group (P < 0.05), but the fluoroscopy frequency of PFNA group was significantly more than that of LCP group (P < 0.05). There was no significant difference in total blood loss between 2 groups (t=-1.686, P=0.096). The patients were followed up 12-24 months in PFNA group and 15-30 months in LCP group. The X-ray reexamination revealed fracture healing at (12.667±2.527) weeks in patients of PFNA group, and at (13.364±1.194) weeks in the others of LCP group except 1 case of nonunion, showing no significant difference (t=-1.443, P=0.154). There was no significant difference in Harris hip score between PFNA group (84.611±7.076) and LCP group (81.785±7.500) at 12 months after operation (t=1.626, P=0.109). The early complication rate and late complication rate were 16.7% (6/36) and 5.6% (2/36) in PFNA group and were 9.1% (3/33) and 9.1% (3/33) in LCP group, all showing no significant difference between 2 groups (χ2=0.871, P=0.481; χ2=0.320, P=0.665). Conclusion Both PFNA and LCP have good effectiveness in the treatment of intertrochanteric fractures with the lateral unsubstantial femoral wall in the elderly patients. Each has its own advantages and disadvantages.
