    Hip Arthroplasty for Failed Internal Fixation of Intertrochanteric Fractures

    Ju-Oh Kim, MD, Hong-Man Cho, MD, Cheol Park, MD, Ju-Hyun Sim, MD

    Hip Pelvis 2012; 24(2): 94-101
    Purpose: To analyze the clinical and radiological results of hip arthroplasty following the failed internal fixation of intertrochanteric fractures of the femur.
    Materials and Methods: We analyzed the reasons for failure in 29 cases of hip arthroplasty from January 1997 through December 2008 in which the hip arthroplasty was necessary due to failed internal fixation of an intertrochanteric fracture of the femur. Furthermore, we tried to find pitfalls encountered when performing the operations. We assessed those patients and drew both clinical (Harris hip score, HHS) and radiological results. The follow-up period was 34.2 months(12-96 months), on average.
    Results: The average operating time was 174 min.(115-205 min.) and the mean amount of perioperative bleeding was 1,335 ml(759-2,450 ml). The amount of packed RBC transfusion was 2.8 units(0-10units) on average. We could see prolonged operation time and a large amount of blood loss as we performed both the removal of the previously fixed implant and reduction of the displaced bone fragment simultaneously. The mean Harris hip score of the patients was improved from the preoperative score of 43 to the postoperative score of 85.7. No cases showed any radiological signs of loosening of acetabular cups or femoral stems, although an articular dislocation and a postoperative joint infection occurred.
    Conclusion: Although hip arthroplasties performed because of a failure in internal fixation could provide relatively satisfactory outcomes, as they result in extended surgery time and greater blood loss, a requirement for higher-level surgical skills, and greater consideration required for the systemic conditions of patients before performing surgery.

    Injury of the Superficial Femoral Artery Secondary to an Unstable Intertrochanteric Fracture - A Case Report -

    Won Ro Park, MD, Min Soo Kang, MD, Kyung Taek Kim, MD, Kyu Pill Moon, MD

    Hip Pelvis 2012; 24(4): 338-341
    Injury of the femoral artery with a femoral intertrochanteric fracture is rare, and usually occurs on the deep femoral artery during surgery. We experienced a case of preoperative injury of the superficial femoral artery by a lesser trochanteric fragment. We repaired the femoral artery through an anterior approach before internal fixation.

    Hemiarthroplasty for Hip Fractures in Elderly Patients over 80 Years Old - Comparative Analysis between Femoral Neck Fracture and Intertrochanteric Fracture -

    Chae-Hyun Lim, MD, Young-Yool Chung, MD, Jeong-Seok Kim, MD, Chung-Young Kim, MD

    Hip Pelvis 2013; 25(1): 44-50
    Purpose: The purpose of this study is to investigate the relative surgical risk and problems in hip hemiarthroplasty for treatment of an unstable intertrochanteric fracture in elderly patients over 80 years old.
    Materials and Methods: Between April 2005 and May 2010, 58 patients whose age was over 80 years were available for inclusion in this study. They were divided into two groups: group 1 included 30 patients with femoral neck fracture and group 2 included 28 patients with intertrochanteric fracture. No significant differences in average age, concomitant disease, and walking ability before development of fracture were noted between the two groups. The following factors, including interval from development of fracture to operation, operation time, amount of blood loss, start time of walking after operation, duration of hospital stay, complications, revision rate, and walking ability were compared between the two groups.
    Results: Operation time was an average of 85.2 minutes in group 1 and 97.5 minutes in group 2(P=0.03). The amount of bleeding was an average of 483 cc in group 1 and 695 cc in group 2(P=0.006). Similar results for walking start and recovery of walking ability after operation were observed in the two groups. No significant differences were observed in duration of hospital stay, complications, and revision rate. While 25 patients in group 1(83.3%) showed restoration of walking ability after operation to the same level of walking before injury, 19 patients in group 2(67.8%) showed restoration of walking ability postoperatively.
    Conclusion: Even though patients in group 2 showed a longer operation time and a higher amount of blood loss, compared with those in group 1, patients in group 2 had similar surgical risk and complications, compared with those in group 1. Therefore, primary hip hemiarthropalsty could be a good treatment option for intertrochanteric fracture in elderly.

    Analysis of the Risk Factors and Clinical Outcomes of Femoral Intertrochanteric Fractures in Patients over 65 Years Old

    Chul Hong Kim, MD, Kyu Yeol Lee, MD, Sung Soo Kim, MD, Myung Jin Lee, MD, Lih Wang, MD, Hyeon Jun Kim, MD, Jung Mo Kang, MD

    Hip Pelvis 2013; 25(2): 127-134
    Purpose: This study examined therelationship between the clinical outcome and risk factors of intertrochanteric femoral fractures in patients over 65 years old.
    Materials and Methods: From January 2000 to March 2012, three hundred and twenty one patients older than 65 years, who underwent surgeryfor intertrochanteric femoral fractures, were evaluated. The following parameters wereanalyzed: the patient risk factors, such as age, sex, smoking, drinking history, cardiovascular disease, cerebrovascular disease and delayed days to surgery; admission day of the week; anesthetic method; operation time by perioperative care related to clinical outcome including postoperative mortality; and complications.
    Results: An analysis of the risk factors revealedfemale patients to have a 13% higher mortality (P=0.043). Aduration of surgerylonger than 3 hours was associated with a 29.1% and 20.8% higher mortality and complication rate, respectively (P<0.001, P=0.027). Asurgical delay of four days or more after admission wasassociated with a 20.1% and 18.8% higher mortality risk and complication rate, respectively (P<0.001, P<0.001). Smoking, drinking history, underlying disease, anesthetic method, and operation time had no significant effect on the outcome.
    Conclusion: In addition to recognizing the importance of patient-related risk factors, modifying the operative factors, such as reducing surgical delays and method of anesthesia, can reduce the mortality and postoperative complications of intertrochanteric femoral fractures.

    Clinical and Radiologic Outcomes among Bipolar Hemiarthroplasty, Compression Hip Screw and Proximal Femur Nail Antirotation in Treating Comminuted Intertrochanteric Fractures

    You-Sung Suh, MD, Jae-Hwi Nho, MD*, Seong-Min Kim, MD*, Sijohn Hong, MD*, Hyung-Suk Choi, MD, Jong-Seok Park, MD*

    Hip Pelvis 2015; 27(1): 30-35
    Purpose: In comminuted intertrochanteric fractures, various operative options have been introduced. The purpose of this study was to determine whether there were differences in clinical and radiologic outcomes among bipolar hemiarthroplasty (BH), compression hip screw (CHS) and proximal femur nail antirotation (PFNA) in treating comminuted intertrochanteric fractures (AO/OTA classification, A2 [22, 23])
    Materials and Methods: We retrospectively evaluated total 150 patients (BH, 50; CHS, 50; PFNA, 50) who were operated due to intertrochanteric fractures from March 2010 to December 2012 and were older than 65 years at the time of surgery. We compared these three groups for radiologic and clinical outcomes at 12 months postoperatively, including Harris Hip Score, mobility (Koval stage), visual analogue scale and radiologic limb length discrepancy (shortening).
    Results: There was no statistical significance among three groups in clinical outcomes including Harris Hip Score, mobility (Koval stage), visual analogue scale. However, there was significant differences in radiologic limb discrepancy in plain radiographs at 12 months postoperatively (radiologic shortening: BH, 2.3 mm; CHS, 5.1 mm; PFNA, 3.0 mm; P=0.000).
    Conclusion: There were no clinical differences among BH, PFNA, and CHS in this study. However, notable limb length shortening could be originated during fracture healing in osteosynthesis, compared to arthroplasty (BH

    The Fixation Method according to the Fracture Type of the Greater Trochanter in Unstable Intertrochanteric Fractures Undergoing Arthroplasty

    Doohoon Sun, MD, Byeong-Seop Park, MD, Gun-Il Jang, MD, Bongjoo Lee, MD

    Hip Pelvis 2017; 29(1): 62-67
    Purpose: We conducted a study on patients who underwent hip joint arthroplasty because of unstable femur intertrochanteric fractures with greater trochanter bony fragments. After dividing patients into three groups depending on their fracture patterns, we evaluated the clinical and radiological outcomes of different operation methods applied to each of these groups.
    Materials and Methods: Using Evan’s classification, we defined an unstable intertrochanteric fracture as those characterized as stage 4 or 5. Of the 137 patients presenting with an intertrochanteric fracture with osteoporosis (bone mineral density, <–2.5) between March 2014 and October 2015, 63 met the eligibility criteria and were included in this study. Next, patients were divided into three groups based on their greater trochanter fracture patterns (discerned with three-dimensional computed tomography images); different fixation methods were applied to each group by a single orthopaedic surgeon.
    Results: Taken as a whole, 50 out of 63 patients experienced no reduction in walking distance in their daily lives. Harris hip score increased from 74.8 to 85.7 point and we considered this a relatively good result. Radiologically, we observed complete bone union in 62 cases (98.4%); the lone exception was in a patient who experienced osteolysis. There were also 3 cases who removed greater trochanter reattachment device due to broken implant and 1 case of dislocation.
    Conclusion: The different fixation methods applied to three distinct groups with varying fractures patterns were successful in achieving proper reduction and fixation of greater trochanteric fractures. We also observed reduced bone union periods when arthroplasty was performed in patients with unstable intertrochanteric fractures. Lastly, we believe these approaches may also aid in achieving early ambulation and early rehabilitations.

    Radiographic Outcomes of Osteosynthesis Using Proximal Femoral Nail Antirotation (PFNA) System in Intertrochanteric Femoral Fracture: Has PFNA II Solved All the Problems?

    Won Chul Shin, MD, PhD, Jung Dong Seo, MD, Sang Min Lee, MD, Nam Hoon Moon, MD*, Jung Sub Lee, MD, PhD*, Kuen Tak Suh, MD, PhD

    Hip Pelvis 2017; 29(2): 104-112
    Purpose: We evaluated the geometric discrepancies between the proximal femur in Koreans and two types of proximal femoral nail using plain radiographs.
    Materials and Methods: A total of 100 consecutive patients (38 treated with proximal femoral nail antirotation [PFNA], 62 PFNA II) with intertrochanteric fracture were retrospectively identified. The minimum follow up period was 32 months. The geometric analysis of the proximal femur was performed using preoperative true hip antero-posterior radiographs of the unaffected side, and the data were compared with the PFNA and PFNA II dimensions. Postoperative assessments were performed using postoperative radiographs for the proximal protruding length of nail tip, quality of reduction, implant position and the presence of lateral cortical impingement.
    Results: The geometric dimensions of the proximal femur were different between the two proximal femoral nail types. No impingement was detected in patients treated with PFNA II, whereas 13 cases of lateral impingement were observed in patients treated with PFNA. A significant association was observed between the short proximal femur and the presence of lateral cortical impingement (P=0.032) and between impingement and intraoperative reduction loss (P=0.012). Proximal protrusion of the nail tip was seen in 71 patients and no difference was observed between two groups.
    Conclusion: Our study demonstrates that the flat lateral surface of PFNA II can avoid lateral cortical impingement, which provide better fixation for intertrochanteric fracture. However, there was still a problem associated with longer proximal end of PFNA II compared with the proximal femoral length in Korean.

    Selecting Arthroplasty Fixation Approach Based on Greater Trochanter Fracture Type in Unstable Intertrochanteric Fractures

    Min-Wook Kim, MD, Young-Yool Chung, MD , Sung-an Lim, MD, Seung-Woo Shim, MD

    Hip Pelvis 2019; 31(3): 144-149
    Purpose: To evaluate the success rate of fixation approaches for greater trochanter (GT) fracture types in those with unstable intertrochnateric fractures.
    Materials and Methods: Forty-four patients who underwent arthroplasty for unstable intertrochanteric fractures between January 2015 and November 2017 and followed-up more than six months were included in this study. The fractures of GT were classified into one of four types (i.e., A, B, C, and D) and fixed using either figure-8 wiring or cerclage wiring according to fracture type. Fractures were type A (n=7), type B (n=20), type C (n=6), and type D (n=11). Type A and B, which are fractures located above the inferior border of GT were fixed using figure-8 wiring and/or adding cerclage wiring. On the other hand, all type C and D fractures, which were located below the inferior border, were fixed using cerclage wiring. Fixation failure was defined as breakage of wire and progressive migration of GT fragment greater than 5 mm on follow-up radiographs.
    Results: The most common GT fracture types were B and D, both of which are longitudinal fractures. The success rates of fixation were 85.7% (6 out of 7 cases) for the treatment of type A, 90.0% (18 out of 20 cases) for the treatment of type B, and 100% for the treatment of types C (6 out of 6 cases) and D (11 out of 11 cases).
    Conclusion: We note high success rates following fixation methods were selected based on the GT fracture type.

    Purpose: We analyzed the radiologic and clinical outcomes of osteosynthesis using a Richard compression hip screw (RCHS) alone or RCHS with a trochanteric stabilizing plate (TSP) in patients with an intertrochanteric fracture.
    Materials and Methods: From January 2006 to December 2008, 23 patients (23 cases) underwent osteosynthesis using only RCHS and 24 patients (25 cases) underwent osteosynthesis using RCHS and TSP. We evaluated the classification of fractures, the amount of collapse and shortening, and the duration of fracture union. We used a Koval classification for the evaluation of clinical outcomes.
    Results: The amount of collapse and shortening in the RCHS-only group was statistically greater than the amount in the RCHS-with-TSP group. The union duration of fracture was 5.3 months in the RCHS-only group and 6.6 months in the RCHS-with-TSP group. The clinical outcomes in the RCHS-with TSP-group were better than the RCHS-only group. We had one case of fixation failure in the RCHS-only group and none in the RCHS-with-TSP group. There were no perioperative systemic complications or death.
    Conclusion: In patients with unstable intertrochanteric fractures, we can prevent the cut out of the lag screw or screw loosening with the use of pressurized PMMA-augmented RCHS. However, we cannot prevent excessive collapse and shortening, especially in patients with severe osteoporosis, a small diameter of the femur neck, or concealed fractures. In the case of these patients, we recommend you to use RCHS with TSP for the prevention of excessive collapse and shortening.
