ABSTRACT
Objective:To investigate the effect of a degradable high-purity magnesium screw in fixing the greater trochanter bone flap of a lateral circumflex femoral artery transverse branch in the treatment of ischemic necrosis of femoral head in young and middle-aged adults.Methods:From February 2017 to February 2019, 12 cases (15 hips) of young and middle-aged patients with avascular necrosis of femoral head were treated in the Department of Orthopaedic of Affiliated Zhongshan Hospital of Dalian University. The age of patients was 30-53 years old. According to Association Research Circulation Osseous (ARCO), 2 hips were graded in stage II b, 4 in ARCO II c, 1 in ARCO III a, 5 in ARCO III b, 2 in ARCO III c and 1 in ARCO IV. The greater trochanter bone flap with a lateral circumferential vascular branch was used to fill the necrotic area, and fixed by a biodegradable high purity magnesium screw in the bone flap transfer. At 3, 6 and 12 months postoperation, the patient came to the hospital outpatient clinic for follow-up, and then were reviewed once a year. Imaging efficacy was evaluated by comparing preoperative and postoperative imaging. The Harris score and Visual Anoalogue Scale (VAS) score were tested at 12 and 24 months after surgery. The Harris score and VAS score before and after surgery were compared by Friedman test, and P<0.05 was considered statistically significant. Results:All 12 patients (15 hips) were entered in the 24-36 months of follow-up. At 12 and 24 months after surgery, Harris score was found at 87 (86, 92) and 90 (87, 92) respertively, which were both higher than that before surgery [59 (52, 74)] with a significant statistical difference ( Z=-3.743, Z=-4.473, P<0.05). However, there was no significant difference in Harris scores between 12 and 24 months after the surgery ( Z=-0.730, P>0.05). At the 12 and 24 months after surgery, VAS score was found at 3 (2, 3) and 2 (1, 3) respertively, which were both lower than that before surgery [6 (5, 6) ] with a significant statistical difference ( Z=-3.560, Z=-4.656, P<0.05). There was no statistical difference in VAS scores between 12 and 24 months after surgery ( Z=-1.095, P>0.05). X-ray and CT scan showed that the bone flaps healed well and the areas of osteonecrosis were repaired. Thirteen femoral heads were in good shape, and 2 femoral heads had further collapse of hips. No patients underwent joint replacement surgery at the time of last follow-up. Conclusion:Fixation of the greater trochanter flap of lateral circumflex femoral artery transverse branch with a degradable high-purity magnesium screw can ensure the healing of the flap at the implantation site and avoid the displacement and shedding of the flap. It is a new therapeutic option to treat the avascular necrosis of femoral head of young and middle-aged people.
ABSTRACT
BACKGROUND: The importance of the lateral wall of the femoral trochanter in the intertrochanteric fracture has been paid more and more attention. The research on the classification of the external wall in guiding clinical operation has become a hot issue. OBJECTIVE: To review the treatment strategies of different lateral wall types of intertrochanteric fractures, and the selection of the built-in materials, provide reference and help for future clinical research. METHODS: The first author searched the Chinese database ofWanfang and China National Knowledge Infrastructure with the keywords of “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. Meanwhile, PubMed English database was retrieved with the keywords “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. The retrieval time was from May 2009 to May 2019. A total of 166 literatures were retrieved. According to the inclusion and exclusion criteria, 47 literatures were selected as the research object and summarized. RESULTS AND CONCLUSION: (1) During the surgical treatment of intertrochanteric fracture of the femur, intramedullary fixation system and extramedullary fixation system have their own advantages and disadvantages. After full analysis of lateral femoral trochanter wall classification and reasonable preoperative evaluation, it is a combination of theory and practice. Signing, correctly assessing the severity of fractures and judging the prognosis, and fully preoperative evaluation can greatly help the patient’s treatment effect and prognosis. (2) It is a basic quality of doctors and a responsible attitude towards patients to formulate different treatment plans according to their economic conditions and physical qualities. “Individualization” has become the future development trend. (3) There are still many disputes in the treatment of intertrochanteric fractures. More clinical research and data support are needed in the future to solve and improve it.
ABSTRACT
@#Isolated apophyseal avulsion of the greater trochanter is a rare condition in the paediatric population, frequently related to avascular necrosis of the femoral head. Since there are few cases in the literature, there is no consensus regarding the best treatment of this injury. Our study describes the case of a 9-year-old patient with an avulsion of the right greater trochanter. A minimally invasive osteosynthesis was performed, achieving complete clinical and radiographic healing of the patient and no long-term complications after four years.
ABSTRACT
Background: The anatomy of the proximal femur comprises important landmarks for many orthopedic surgical procedures. However, this area exhibits morphological differences depending on race, gender and age. Besides being the insertion area of the hip flexor muscles, the lesser trochanter is also used as an angular reference in many orthopedic surgical procedures. The aim of this study is to investigate the morphologic relationship of the lesser trochanter with the femoral neck and greater trochanter.Methods: Around 67 dry femur bones (32 left, 35 right) belonging to humans of unknown gender that belong to the Ankara University Medical Faculty, Department of Anatomy were used in this study. The morphologic relationship of the lesser trochanter (TRMI) with the femoral neck (FN) and greater trochanter (TRMJ) was studied and the results were provided in a table.Results: The measured mean lesser trochanter and greater trochanter tip distance was 67.5±4.9mm (60mm-75mm). The angle between the tip of the lesser trochanter and the center of the femoral neck was measured as 35.050±5.060 (290-420) degrees. The distance between the tip of the lesser trochanter and the center of the femoral neck was measured as 15±2.8mm (10mm-20mm).Conclusions: In addition to the angular relationship of the lesser trochanter with the femoral neck, its relationship in terms of distance with the greater trochanter and femoral neck are the anatomic relationships that are noteworthy for the lesser trochanter, which is used as a landmark during orthopedic surgical procedures.
ABSTRACT
Objective: To observe the curative effects of artificial femoral head replacement using sternal wire binding and plate fixation in the treatment of the patients with unstable intertrochanteric fracture, and to provide the basis for its treatment. Methods: A total of 52 elderly patients with intertrochanteric fracture treated with artificial femoral head replacement were divided into sternal wire binding group (the patients were given sternal wire binding of greater trochanter, n=28) and plate fixation group (the patients were given plate fixation of greater trochanter, n=24). The operation time, blood loss, the drainage volumes after operation, the time of getting off the bed first, the incidences of early complications, and the Harris scores of hip joint at the discharge time and 1 month, 3 months, 6 months and 12 months after operation of the patients in two groups were recorded. Results: Compared with plate fixation group, the operation time of the patients in sternal wire binding group was decreased (P0. 05). Conclusion: Compared with plate fixation, sternal wire binding of the greater trochanter in femoral head replacement in the treatment of the patients with unstable intertrochanteric fracture has the advantages of shorter operative time, less blood loss volume, better postoperative recovery of hip joint function, which is suitable for the clinical application.
ABSTRACT
PURPOSE: Proximal femur fractures are classified into intracapsular neck fractures and extracapsular trochanteric fractures, and several related treatment recommendations in elderly patients have already been introduced. Importantly, we have observed cases of combined intra and extracapsular fractures (i.e., ipsilateral neck and trochanter fractures). The purpose of this study is to report the outcomes of combined neck and trochanter fractures of the femur treated with cephalomedullary nail (CMN) in elderly patients. MATERIALS AND METHODS: From January 2010 to December 2014, 410 patients with proximal femoral fractures were fixed using CMN; among this group, 37 patients with combined neck and trochanter fractures were identified. Two of these patients died fewer than three months after injury and another two did not return for follow-up. Thirty-three patients were included and reviewed retrospectively in this study. RESULTS: All patients were injured by simple fall. Bone union was obtained in 28 of 33 patients. Of the five patients who failed treatment, three experienced implant penetration through head (cut-through and cut-out), one had breakage of CMN and the last one had a loosening of internal fixation device with persistent non-union at final follow-up. The former four patients underwent hip replacement surgery and the latter refused surgery because he had low demand in daily life and many medical problems. CONCLUSION: Eighty-five percent of elderly patients with combined neck and trochanter fractures of the femur treated with CMN achieved bone union; these complex fractures require more accurate reduction than usual extra-articular intertrochanteric fractures.

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.

ABSTRACT
PURPOSE: To evaluate the interstitial and appositional growth of greater trochanter post-screw apophysiodesis in Legg-Calve-Perthes (LCP) disease. MATERIALS AND METHODS: A total of 17 patients, who were diagnosed with LCP and underwent greater trochanter screw apophysiodesis and metal removal between December 2003 and December 2012, and were followed-up for at least 4 years, were selected. Anterioposterior radiologic images were taken in each process of apophysiodesis, metal removal, and last follow-up. From such images, articulotrochanter tip distance (ATD), trochanter tip-screw distance (TSD), trochanter tip-trochanter lower margin distance (TLD), and screw-trochanter lower margin distance (SLD) were measured. Appositional growth and greater trochanter growth rates were compared using paired t-test, independent t-test, and correlation analysis. RESULTS: The average ATD of the affected and unaffected sides was 14.2 and 16.8 mm, respectively at apophysiodesis and 9.2 and 14.8 mm at the last follow-up, with a significantly greater decrease observed on the affected side the unaffected side (p=0.030). TLD of the affected side during the follow-up increased 11.0 mm, from an average of 30.8 to 41.8 mm, while the un-affected side increased 14.3 mm, from an average of 26.7 to 41.0 mm. The growth of greater trochanter after the operation in the affected side was 76.7% of that in unaffected side. The ratio of TLD of the affected side to the unaffected side was significantly reduced, from 1.15 to 1.02 (p=0.014) at the final follow-up. TSD was significantly increased from 4.5 to 14.4 mm at metal removal (p < 0.001) and increased to 17.0 mm at the last follow-up. Moreover, the ratio of TSD to SLD was significantly increased from 0.20 to 0.74 at metal removal (p < 0.001) and increased to 0.84 at the final follow-up. CONCLUSION: The results of this study showed that screw apophysiodesis can suppress the overall growth, but not the appositional growth of the greater trochanter. Therefore, screw apophysiodesis may not be a good procedure to inhibit the growth of greater trochanter.

Solitary Osteochondroma is the most common benign bone tumor, and occurs most frequently in the proximal humerus, tibia, and distal femur. It rarely affects proximal femur and talus. Therefore, we report two cases of solitary osteochondroma, which were found at these rare sites (one at lesser trochanter and another at talus) with a brief review of literature and discussion of clinical features and management..
ABSTRACT
Introduction: Osteosynthesis of the femur using an interlocking nail is the gold standard for treating diaphyseal fractures of the femur. There are two established entry points for the antegrade interlocking nails which is the piriformis fossa or the greater trochanter. It has been reported that varus malalignment was frequently seen in proximal femur fracture which were treated with interlocking nail utilizing the greater trochanter entry point. The study was done to find out if the problem was of significance. Materials and Methods: This was a retrospective study which included 179 patients with femur fractures which were treated from January 2013 till September 2015 in one Hospital. They were treated with interlocking nail either by utilizing the piriformis fossa (PF) or the greater trochanter (GT) entry points. Post-operative radiographs of the femur were used to measure the varus deformity. Results: Out of 179 patients, there were 5 patients who were reported to have unacceptable varus malalignment (2.79%). These 5 patients were out of the 88 (5.68%) patients utilizing the greater trochanter as the entry point. The same 5 patients were out 90 patients that were diagnosed with proximal femur shaft fractures (5.55%). Analysis with logistic regression was statistically not significant. Conclusion: There was higher rate of varus malalignment seen in proximal femur shaft fractures treated with interlocking nails utilizing the greater trochanter entry point. The incidence of varus malalignment was not significant statistically. Key Words: interlocking nail; greater trochanter entry point; varus deformity; femur shaft fracture
ABSTRACT
Ischiofemoral impingement syndrome is a rare clinical entity characterized by chronic groin, buttock or hip pain associated with radiographic evidence of narrowing of the space between the lesser femoral trochanter and the ischial tuberosity. Introduction of magnetic resonance imaging to the clinical practice as well as the establishment of the radiological definition of the abnormal ischiofemoral distance has led to an increasing interest in this condition. Ischiofemoral impingement syndrome is a poorly understood disorder of chronic pain, especially regarding its treatment. The authors present two cases of primary ischiofemoral impingement syndrome successfully treated with a minimally invasive surgical technique. With this endoscopic technique, it was possible to resect the lesser trochanter and restore the ischiofemoral space. Immediate clinical and functional improvement was reported by both patients.

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.

PURPOSE: There is no consensus on a clear intraoperative guideline for judging the coronal plane alignment following reduction of trochanteric fractures. Complex angular measurements using fluoroscope monitors are tedious. Therefore the relation of the horizontal line from the tip of the greater trochanter (GT orthogonal) and femur head center (HC orthogonal) was studied to define this line as a criterion for predicting varus-valgus malalignment. MATERIALS AND METHODS: We studied this relation in 200 standing orthoradiograms which included 100 males and 100 females. The images were digitally analyzed using the picture archiving and communication system. GT orthogonal line and HC orthogonal line were evaluated. The distance of these lines was measured as trochanter center distance (TCD) and its correlation with angular parameters like neck shaft angle, medial proximal femoral angle with reference to anatomical axis (aMPFA) and lateral proximal femoral angle with reference to mechanical axis (mLPFA) were analyzed. RESULTS: In all patients, the GT orthogonal line passed either at or above the center of the head. Overall mean of TCD was 7.22 mm, ranging from 0 to 17.57 mm. TCD was found to show strong correlation with angular parameters like aMPFA, mLPFA and neck shaft angle. TCD was less than one fourth of the corresponding head diameter in around 90%. Therefore following reduction of trochanteric fractures, the GT orthogonal line should pass through the superior juxta central quadrant of the femoral head. CONCLUSION: This line can be represented by a guide wire with fluoroscopy during surgery. The GT orthogonal line can be used intraoperatively as a simplified tool for prediction of varus/valgus malalignment following the reduction of trochanteric fractures.

Introduction: In orthopaedic surgery, trochanteric region is an important as it’s an entry point, usually lateral side of the great trochanter, although anterior and posterior approaches have variable interest. For implants such as plates and DHS (dynamic hip screw), lateral approach is standard. After skin, fat tissue and fascia lata, vastuslateralismuscle is reached and elevated to approach lateral surface of subtrochanteric area. For implants as intra-medullar nail, minimally invasive approach is in routine use. Despite abundant research of general femoral morphology, especially its specific morphological parts (femoral head, neck, shaft, and its distal part involved in knee joint). Materials andmethods: Study on 158 dry adult human femur of unknown age&sex collected fromthe department of anatomy and phase I students of KBNIMS, Kalaburagi, Karnataka. The broken or non-dried specimens were excluded fromthe study. Results: The third trochanter was present in 4.43% of the femora. Although the incidence was higher on the right side it was not statistically significant. Discussion: Another studywhich reported the side variations inWhites andNegroes, documented higher incidence on right side in White and on left side in Negro population; it also reported the trait to be more common in females in bothWhites and Negroes. Conclusion: The presence of third trochanter at the proximal part of the femur has been found to alter the break lines in the pertrochanteric fracture patients. This study dealt with the incidence of third trochanter in north Karnataka region.

ABSTRACT
PURPOSE: To compare treatment results obtained using the trochanteric (Sirus nail) entry portal with those obtained using the Piriformis fossa (M/DN) entry portal during intramedullary (IM) nailing of femur shaft fractures. MATERIALS AND METHODS: Four hundreds and thirty-two patients treated for femur shaft fracture using IM nails from February, 2001 to May, 2010 were divided into two groups. group 1 was composed of 180 patients treated through the trochanteric (Sirus nail; n=180) entry portal, while group 2 contained 170 patients treated through the piriformis fossa (M/DN nail; n=170) entry portal. We compared the clinical and radiographic findings of both groups to evaluate the treatment results. RESULTS: Functional result, range of motion and union time (18, 20 weeks) were similar in both groups. The operation time of patients in the over-weighted group was 90 minutes in group 1 and 120 minutes in group 2 (p0.05). There were 18 iatrogenic fractures in group 1 and 4 in group 2 (p<0.05). CONCLUSION: There was not much difference in complications based on clinical and radiographic findings of both groups. For groups using the trochanteric entry portal, the operation time was shorter and blood loss was lower than in groups using the piriformis entry portal. Iatrogenic fracture occurred more often in the group using the trochanteric entry portal than in the group using the piriformis entry portal.

PURPOSE: We classified fractures of the greater trochanter (GT) and evaluated fracture fragment stability according to GT type. MATERIALS AND METHODS: A total of 43 patients with an unstable intertrochanteric fracture treated between January 2007 and July 2009 with bipolar hemiarthroplasty were included in this study. GT fractures were classified as type A, B, C, or D and fixed using either cerclage wiring alone, cerclage wiring and non-absorbable suture or a greater trochanteric reattachment (GTR) plate. RESULTS: Type A fractures were fixed using cerclage wiring with non-absorbable suture in two cases, cerclage wiring in six cases and GTR plate in seven cases. Failure occurred in three cases of type A fractures treated with cerclage wiring alone. A total of 11 type B fractures were fixed with cerclage wiring (7), cerclage wiring and non-absorbable suture (3) and GTR plate (1). There was no failure of type B fractures. Type C fractures were fixed using cerclage wiring with non-absorbable suture in one case and GTR plate in three. There was no fixation in three cases. Of 10 type D fractures, six were treated with cerclage wiring and one with GTR plate. Fixation was not performed in three patients. There was no failure in type C and D type fractures. CONCLUSION: Fracture fragment stability differed according to fracture types. Cerclage wiring alone was insufficient to fix type A fractures, so type A fracture required a stronger fixation method.

PURPOSE: The aim of this study was to analyze the use of a compression hip screw with a trochanter stabilizing plate for treatment of reverse oblique intertrochanteric fractures. MATERIALS AND METHODS: We reviewed the results of 33 cases of reverse oblique intertrochanteric fracture treated with a compression hip screw with a trochanter stabilizing plate from January 2000 to December 2012 which were followed-up for more than one year. We evaluated postoperative bone union period, change of neck-shaft angle, sliding of hip screw, and other complications. RESULTS: Of 33 patients, satisfactory reduction was achieved in 28 patients. Five patients had an unsatisfactory reduction, with two cases of excessive screw sliding, one of broken metal, one of varus deformity, and one of internal rotation deformity. We performed corrective osteotomy in varus and internal rotation deformity and partial hip replacement in a case of excessive screw sliding. Bone union was achieved in 29 patients, and the average bone union period was 19.2 weeks. CONCLUSION: We consider that a compression hip screw with a trochanteric stabilized plate is a good option for treatment of reverse oblique intertrochanteric femoral fractures. However, adequate fracture reduction and ideal implant placement are a basic necessity for successful treatment.
