RESUMO
BACKGROUND: The trochanteric bursae are often left unrepaired after total hip arthroplasty (THA) and they retract posteriorly over the muscle belly of the piriformis. Deep gluteal syndrome (DGS) is a multifactorial condition presenting as buttock pain and is attributed to nondiscogenic sciatic nerve irritation or impingement causes. The purpose of this study was to investigate the relationship between bursal repair and incidence of DGS in patients undergoing THA. METHODS: This prospective randomized trial included patients treated with a THA between January and December 2022 for a diagnosis of primary osteoarthritis. Patients were randomized into 2 groups: group 1 underwent a routine bursal repair, while group 2 did not, leaving the bursae unrepaired. Follow-up was performed on the 15th, 30th, and 90th day postoperatively with clinical scores, physical examinations, and laboratory tests. In this cohort of 104 patients, mean age was 55 years (range, 26 to 88). Demographic variables as well as range of motion and overall clinical results showed no significant difference between the groups. RESULTS: DGS rates were significantly more common in the patients who had an unrepaired bursa (group 2) both on the 30th and 90th postoperative days, while comparison of lateral trochanteric pain on palpation showed similar results between the groups. CONCLUSIONS: DGS is common in individuals who have unrepaired trochanteric bursal tissue following a THA. Despite its higher frequency, these symptoms did not have a substantial impact on the overall clinical scores, which remained consistent across the study groups.

PURPOSE: Greater trochanter pain syndrome (GTPS) is highly discussed during spine surgeons, accompanies lumbar pain and complicates differential diagnosis. The aim is to raise awareness among physicians and demonstrate the lumbar spine degenerative diseases (LSDD) association with GTPS. METHODS: A retro-prospective analysis enrolled 172 patients with LSDD with GTPS signs. Group I - retrospective (n = 112), group II - prospective (n = 60). Patients of group II with the confirmed diagnosis clinically and by the ultrasound recieved a GCS injection (Betamethasone 2 mg\ml + 5 mg\ml - 1.0). Also the VAS, X-ray and SPSS Statistics package were used. RESULTS: 112 patients in group I, 89 (79.5%) had increased pain in the hip early postOp to 7.8 points by VAS. All patients required trigger point injections of GCS and 68 (77%) received a repeat injection. 76 from 112 patients were tracked for long-term results, and recurrence of GTPS was detected in five people who treated conservatively for three months without dynamics. They were identified GTPS by ultrasound. During the injection, 39 from 43 (90%) patients noted pain reduction to 2.1 by VAS, but symptoms of radiculopathy or spinal stenosis persisted. Two patients (5%) did not note any changes. Two patients (5%) noted complete pain regression and refused the surgery. CONCLUSION: Timely detection of GTPS among spinal surgeons influences tactics and, in some cases, allows one to avoid unnecessary surgical interventions. In turn, ignoring the symptoms of GTPS in the preoperative period can lead to pain intensification in the greater trochanter after surgery for degenerative diseases of the spine.

BACKGROUND: The objective of this study was to evaluate the reoperation and complication rate following trochanteric plate fixation of greater trochanter (GT) periprosthetic femur fractures associated with total hip arthroplasty and to identify risk factors for subsequent reoperation, nonunion, and hardware failure (plate/cable breakage or migration). METHODS: Between 2010 and 2020, 44 patients who had 44 periprosthetic greater trochanter fractures at mean follow up of 2 years were retrospectively reviewed. Initial injury radiographs as well as immediate and final follow-up radiographs were evaluated. Subsequent reoperations, nonunion, and cases of hardware failure were identified. There were 22 (50%) Vancouver B2 fractures and 22 (50%) Vancouver A fractures. RESULTS: The 2-year cumulative probability of any subsequent reoperation was 20%. There were 9 total subsequent reoperations. The trochanteric fracture went on to nonunion in 14 patients (39%), and hardware failure occurred in 10 (28%) patients. A trochanteric bolt was used in addition to the trochanteric plate in 6 patients (14%), of which 4 (67%) patients had trochanteric plate displacement and 3 (50%) patients had trochanteric nonunion. Displacement of the greater trochanter prior to fixation was a predictor of subsequent nonunion (77% versus 23%, P = .02). CONCLUSION: In this large contemporary series, there was a high incidence of reoperation (20%) with in the first 2-years following plating of periprosthetic GT fractures, as well as a high rate of nonunion (39%), and hardware failure (28%). Displacement of the GT prior to plating predicted nonunion. LEVEL OF EVIDENCE: Level IV, retrospective observational study.

OBJECTIVE: Greater trochanteric pain syndrome is a common cause of lateral hip pain. Corticosteroid injections are commonly utilized as nonsurgical interventions; however, they are not effective for all patients. This technical case report describes a method for treating greater trochanteric pain syndrome by utilizing cooled radiofrequency ablation. METHODS: The trochanteric branch of the nervus femoralis is identified as providing sensory innervation to the greater trochanter and its surrounding structures. We have identified fluoroscopic targets to block the nerve and perform cooled radiofrequency ablation. We present two patient cases which demonstrated significant pain relief of greater trochanteric pain syndrome with this treatment. CONCLUSIONS: Cooled radiofrequency ablation of the trochanteric branch of the nervus femoralis is a potential treatment for greater trochanteric pain syndrome. This procedure provides a potential steroid-sparing interventional treatment based on reproducible fluoroscopic landmarks.

BACKGROUND: Total hip replacement (THR) in the gold standard surgical treatment for the canine hip. While it has been shown that greater trochanter morphology affects post-operative cementless stem position in humans, trochanter morphology and the effect on cementless stem position has not been extensively evaluated in dogs. The objective of this study was to classify greater trochanter morphology and identify potential associations between trochanter morphology and patient demographics, femoral canal geometry, surgical time, technique modifications, and post-operative stem position in client-owned dogs undergoing cementless THR. RESULTS: In this retrospective study, medical records and radiographs of 135 dogs undergoing 150 cementless total hip replacements from 2013 to 2020 were included. Trochanters were classified in the frontal plane using an ordinal grading system adapted from human THR. A Grade I trochanter denoted a trochanter positioned lateral to the periosteal surface of the lateral femoral cortex, whereas a Grade IV trochanter denoted a trochanter positioned medial to the anatomic axis of the femur. Associations between trochanter grade and other variables were examined using ANOVA, Kruskall-Wallis, or chi-squared tests. Significance was assumed at P ≤ .05. Trochanters were classified as follows: Grade I (44/150, 29.3%), Grade II (56/150, 37.4%), Grade III (44/150, 29.3%), Grade IV (6/150, 4.0%). Grade IV trochanters had lower anatomic lateral distal femoral angle (aLDFA; 91.0 ± 6.2°), angle of inclination (117.7 ± 10.5°), and canal flare index (1.53 ± 0.27). When compared to all groups, Grade IV trochanters were associated with longer surgical times (Grade IV: 227.0 ± 34.2 min; all grades: 183.2 ± 32.9 min) and technique modifications (Grade IV: 83.3%; all grades: 18%). Grade I trochanters had stems placed in valgus (- 1.8 ± 2.33°), whereas Grade II (0.52 ± 2.36°), III (0.77 ± 2.58°), and IV (0.67 ± 2.73°) trochanters exhibited varus stems. Depth of stem insertion was greater (11.2 ± 4.2 mm) for Grade IV trochanters. CONCLUSIONS: Trochanter grade was associated with post-operative stem alignment and translation in the frontal plane. Grade IV trochanters were associated with altered femoral geometry, increased surgical time, technique modifications, and stem insertion depth. Pre-operative greater trochanter classification may prove useful in identifying cases requiring prolonged surgical times or technique modifications.

BACKGROUND: Various authors have successfully demonstrated that the distance from the greater trochanter to the femoral head center (GTFHC) and the distance from the lesser trochanter to the femoral head center (LTFHC) can be used as parameters to determine the recovery of the femoral head center (FHC) during hip arthroplasty. It is necessary to undertake an anatomical study concerning the correlations between the greater trochanter (GT), the lesser trochanter (LT), and the FHC using data obtained from the 3D-CT reconstruction method. METHODS: The study comprised 293 patients (151 males and 142 females), with an average age of 65.06 years. The femoral head diameter(FHD), the linear distance from FHC to GT (GTFHC), and the linear distance from FHC to LT(LTFHC) were all measured and recorded data. The correlation between FHD with LTFHC and GTFHC was assessed using Pearson correlation coefficients, and the ratio of LTFHC and GTFHC to FHD was calculated from this ratio. All measured parameters were compared between the left and right sides and the sexes of the participants. RESULTS: The average ratios of GTFHC/FHD and LTFHC/FHD were 0.99 and 0.95, respectively .96% of the LTFHC had absolute lateral differences of < 4 mm . 92% of the GTFHC had absolute lateral differences of < 4 mm. CONCLUSION: LTFHC and GTFHC are reliable reference parameters for preoperative planning and reconstruction of FHC of hip arthroplasty. The ratio displayed in this research may yield insight into a practical and straightforward method for orthopedic surgeons to perform hip arthroplasty in patients with femoral neck fractures. Ratios from studies based on the same race may be desirable for future work.

BACKGROUND: Isolated greater trochanter fracture (IGT) and conventional hip fracture (HF) affect the same anatomical area but are usually researched separately. HF is associated with high mortality, and its management is well established. In contrast, IGT's effect on mortality is unknown, and its best management strategies are unclear. This study aims to compare these patient populations, their acute- and post-acute care, physical and occupational therapy use, and up to three-year mortality. METHODS: This retrospective cohort study is based on population-wide data of Estonia, where routine IGT management is non-operative and includes immediate weight-bearing as tolerated. The study included patients aged ≥ 50 years with a validated index HF or IGT diagnosis between 2009-2017. The fracture populations' acute- and post-acute care, one-year physical and occupational therapy use and three-year mortality were compared. RESULTS: A total of 0.4% (50/11,541) of included patients had an IGT. The baseline characteristics of the fracture cohorts showed a close resemblance, but the IGT patients received substantially less care. Adjusted analyses showed that the IGT patients' acute care was 4.5 days [3.4; 5.3] shorter they had 39.2 percentage points [25.5; 52.8] lower probability for receiving post-acute care, and they had 50 percentage points [5.5: 36]] lower probability for receiving physical and occupational therapy. The IGT and HF patients' mortality rates were comparable, being 4% and 9% for one month, 28% and 31% for one year, and 46% and 49% for three years, respectively. Crude and adjusted analyses could not find significant differences in their three-year mortality, showing a p-value of 0.6 and a hazard ratio of 0.9 [0.6; 1.3] for the IGT patients, retrospectively. CONCLUSIONS: Despite IGT being a relatively minor injury, the evidence from this study suggests that it may impose a comparable risk on older patients' survival, as does HF due to the close resemblance of the two fracture populations. Therefore, IGT in older patients may signify an underlying need for broad-based medical attention, ensuring need-based, ongoing, coordinated care. TRIAL REGISTRATION: Retrospectively registered.

INTRODUCTION: Greater trochanter pain syndrome (GTPS) is characterized by a persistent and debilitating pain around the greater trochanter. GTPS can be caused by a combination of gluteus medius or minimus tendinopathy, snapping hip or trochanteric bursitis. SOURCE OF DATA: Recent published literatures identified from PubMed, EMBASE, Google Scholar, Scopus. AREAS OF AGREEMENT: Platelet rich plasma (PRP) and corticosteroids (CCS) injections are useful options to manage symptoms of GTPS. AREAS OF CONTROVERSY: Whether PRP leads to superior outcomes compared to CCS injections is unclear. GROWING POINTS: A systematic review and meta-analysis comparing PRP versus CCS in the management of GTPS was conducted. AREAS TIMELY FOR DEVELOPING RESEARCH: PRP injections are more effective than CCS at approximately 2 years follow-up.

BACKGROUND: In our institute, all elderly patients with displaced femoral neck fracture were treated with cemented bipolar hemiarthroplasty (BHA) using the modified Dall approach. To our knowledge, there are no reports on the knot position of the greater trochanter reattachment. The aim of this study was to determine influence of two knot positions (anterior or posterior) on the complications of the greater trochanter. METHODS: This is a prospective non-randomized study conducted on 95 elderly patients (95 hips) from September 2013 to December 2017. The knot position was changed from anterior to posterior alternately. The X-ray images obtained immediately after the operation were compared with those obtained at 3 months postoperatively; thereafter, the status of the greater trochanter was classified into three types: type A, no apparent shifting and fracture; type C, over 1-mm shifting of the fragment; and type F, fracture of the greater trochanter. RESULTS: Regarding age at operation, sex, BMI, size of the greater trochanteric fragment, stem type, and surgeon, there was no significant difference between two groups. In the anterior group, 34 hips (72.3%), 5 hips (10.6%), and 8 hips (17.0%) were classified under type A, C, and F, respectively. In the posterior group, 44 hips (91.7%), 1 hip (2.1%), and 3 hips (6.3%) were classified under type A, C, and F, respectively. There were significantly fewer greater trochanteric complications in the posterior group. CONCLUSIONS: The posterior knot position improved the union of the greater trochanter after BHA compared with the anterior knot position. TRIAL REGISTRATION: We had approved IRB at our hospital clinical research review committee. Retrospectively registered.

PURPOSE: Greater trochanter pain syndrome (GTPS) or lateral hip pain terms include external snapping hip, trochanteric bursitis and gluteus medius or minimus pathology. The aim of this review is to update the most recent knowledge about non-surgical management of peritrochanteric disorders. METHODS: A literature review was performed including articles most relevant in the last years that were focused in non-surgical treatment of peritrochanteric disorders. RESULTS: Conservative treatment still has a place and includes activity modification, NSAIDs, analgesics, physiotherapy, home training, local corticosteroid injection (CSI) and shock wave therapy (SWT). These non-surgical alternatives have demonstrated good clinical results with low rate of complications. CONCLUSION: Most patients tend to resolve GTPS or lateral hip pain with non-surgical management in the mid-term but when everything failed, surgical options should be evaluated. The next frontier that will be a game changer is to determine an individualized treatment plan based on the exact pathology. LEVEL OF EVIDENCE: V.

PURPOSE: Snapping hip is a common clinical condition, characterized by an audible or palpable snap of the hip joint. When the snap is perceived at the lateral side of the hip, this condition is known as external snapping hip or lateral coxa saltans, which is usually asymptomatic. Snapping hip syndrome (SHS) refers to a painful snap, which is more common in athletes who require increased hip range of motion. The aim of this article is to review the most common endoscopic techniques for the treatment of ESHS, as well as their results and limitations. METHODS: This is a review of the current literature of endoscopic surgical procedures and of the results of the treatment of external snapping hip syndrome. RESULTS: The pathogenesis of SHS is mechanical. The initial treatment attempt is conservative, and usually provides good results. Patients who do not respond to conservative management are candidate for surgery. The endoscopic release of the ilio-tibial band or the endoscopic release of the femoral insertion of the gluteus maximum tendon is the most popular technique. CONCLUSION: Endoscopic techniques provide fewer complications compared to open surgery, a lower recurrence rate and good clinical outcomes. More comparative studies with a longer follow-up are required to adequate evaluate the full role of endoscopic techniques in periarticular hip surgery. LEVEL OF EVIDENCE: Level V.

INTRODUCTION: Antegrade nailing of proximal femur or femoral shaft fractures is a proven treatment with good to excellent results. Nonetheless, clinical evidence from Asia indicates that proximal femur nails can be too proud at the greater trochanter (GT) causing irritation for some Asian patients. This study aimed to identify any significant differences in proximal nail misfit for a set of Asian and Caucasian femora. MATERIALS AND METHODS: Two nails (Gamma3, TFNA) were virtually inserted into 63 femoral 3D models (28 Japanese, 4 Thai, 31 Caucasian). In AP, the entry point was 4° lateral for Gamma3 and 5° for TFNA; laterally the same location was used for both. Insertion depth was controlled by aligning the lag screw centre head. The distance of the nail end from the GT was measured at five (medial, lateral, anterior, posterior and centre) reference points (RPs). The correlation between GT height, CCD angle and proximal nail distance to GT was analysed. RESULTS: There was no significant difference between either nail (p = 1.0). The TFNA was overall less prominent than the Gamma3, and significantly less prominent at all RPs except lateral. The Asian femora were 3.76 (p = 0.016) times more likely to have the nail protruding proximally. The Asian subjects were shorter (p < 0.05) than the Caucasians. Their GT height was slightly shorter and CCD angles larger compared to Caucasian (Asian: 41.1 mm, 128.1°, Caucasian: 42.2 mm, 126.4°), but the differences were not significant (p = 0.36). Stature, GT height and CCD angle significantly correlated with nail distance to GT. CONCLUSIONS: This study illustrated a significantly increased incidence of proximal nail protrusion in Asian compared to Caucasian femora, corroborating clinical findings. The combination of shorter stature and GT height and a larger CCD angle in Asians likely contributes to this difference.

INTRODUCTION: Greater trochanter (GT) fractures affect 0.6-29% of patients after direct anterior approach (DAA) total hip arthroplasty (THA). Given the growing popularity of this approach, this study aimed to assess the evolution of the GT fractures during the learning curve, their risk factors and their consequences. MATERIALS AND METHODS: 537 total hip arthroplasties were retrospectively included from May 2013 to December 2017 in a single academic centre. Patient characteristics, perioperative management, clinical consequences and postoperative radiographs were analysed. RESULTS: GT fractures represented 2.4% (n = 13) of the THA, and there was not a decrease with experience. The GT fracture patients did not require any additional support during the surgery, and full weight bearing was always allowed without any restriction. This complication only happened in females, with the risk significantly increased in those > 70 years old (OR = 4.9). There was no specific consequence during the follow-up, mean HHS score was 98.5 and all of the patients were satisfied or very satisfied postoperatively. CONCLUSION: Older osteoporotic women are known to be at risk for GT fracture during DAA THA. Those results reinforce the argument in favour of proper patient selection in DAA to lower the complications since it does not improve with surgeon's experience. LEVEL OF EVIDENCE: Retrospective, consecutive case series; Level IV.

PURPOSE: Greater trochanter (GT) lesions are relatively uncommon. They can be traumatic, infective including tuber-culosis, inflammatory, and neoplastic (primary and metastatic osseous lesions). Although imaging of greater trochanter lesions remains essential for differential diagnoses, an image-guided biopsy is a mainstay for diagnosis and to guide subsequent management. MATERIAL AND METHODS: A retrospective search for the word 'greater trochanter' was performed of a computerised radiology information system (CRIS) of a tertiary referral centre for orthopaedic oncology over a period of 12 years (2007-2019). This revealed 6019 reports with 101 neoplasms. The imaging, histology, and demography were reviewed by a dedicated musculoskeletal radiologist. RESULTS: We identified 101 GT neoplasms with a mean age of 51.5 years (range 6 to 85 years) and a slight female predominance of 1.2 : 1 (46 males and 55 females). Using 30 years of age as a cut-off, we further segregated the patient cohort into 2 groups: 26 (25.74%) lesions in patients less than 30 years age and the remaining 75 (74.26%) lesions in patients over 30 years old. Chondroblastoma was the most common neoplasm in patients below 30 years of age, and metastases were the most common neoplasms in patients over 30 years of age. CONCLUSIONS: Greater trochanter pathologies show a broad spectrum of aetiologies. Imaging including radiographs, computed tomography, magnetic resonance imaging, and nuclear medicine scans help to narrow down the differen-tials diagnosis.
RESUMO
BACKGROUND: A fracture in the isolated greater trochanter is an infrequent type of femoral intertrochanteric fracture. The gluteus medius and gluteus minimus are abducent muscle groups with attachments located on the greater trochanter. Thus, a fracture of the greater trochanter could cause avulsion injury of these attachment points and eventually affect the abducent function of the hip joint and cause chronic pain. Despite these prospects, the impact of a greater trochanter fracture on abducent strength and hip joint function have yet to be investigated. METHODS: Patients who were diagnosed with an isolated greater trochanter fracture (via computed tomography scan and X-ray) and underwent conservative treatment from June 2013 to October 2016 were included in the present study. Magnetic resonance imaging (MRI) was used to verify the morbidity of recessive fractures. Patients' Harris Hip Scores were determined at 3 months, 6 months, and 12 months and the abducent strength and range of motion of the hip joint on the injured side were analyzed and compared to those on the healthy side. RESULT: Among 32 patients, there were 7 individuals diagnosed with isolated greater trochanter fractures by MRI, and 25 individuals whose fractures were found to have extended into the intertrochanteric region, wherein the recessive intertrochanteric region fractures had no relationship with patients' age, gender, or weight. After 12 months of conservative treatment, 7 patients still complained of pain in the hip joint. The average Harris Hip Score was 87.84 ± 4.83, and the abducent range of the hip joint on the injured side (42.02 ± 13.93°) was not significantly different from that of the healthy side (46.24 ± 7.93°). The abducent strength of the hip joint of the injured side was 121.32 ± 41.06 N which was significantly lower than that of healthy side (137.44 ± 42.21 N). CONCLUSION: Results from this investigation suggest that an isolated greater trochanter fracture attenuates the abducent strength of the hip joint, which may be related to injuries of the ligaments and muscles around the greater trochanter. The surgical skills and methods of addressing isolated greater trochanter fractures merit further investigation.

BACKGROUND: To compare the mid-long-term clinical and radiological outcomes between a combination of cortico-cancellous iliac bone graft with vascularized greater trochanter flap (Group A) and isolate iliac bone graft (Group B) in the treatment of Osteonecrosis of the Femoral Head (ONFH). METHODS: From January 2006 to December 2012, 123 patients (135 hips) who underwent abovementioned hip-preserving surgeries were included for analysis. Clinical outcomes were assessed based on Harris Hip Score (HHS) System and The Western Ontario and McMaster University Index (WOMAC) scores between the preoperative and the last follow-up. A series of postoperative X-rays were compared to preoperative images for radiological evaluation. RESULTS: The HHS in Group A and B were enhanced from 50.57 ± 3.39 to 87.60 ± 4.15 and from 50.24 ± 3.30 to 85.18 ± 6.45, respectively, which both showed significance between preoperative and postoperative latest follow-up (p < 0.001). Group A revealed better improvement in terms of HHS (p = 0.017). The WOMAC total, postoperative stiffness, difficulty subscale scores in Group A showed better outcomes when compared to Group B (p < 0.01), while pain improvement between these two groups revealed no significance (p = 0.402). Besides, Group A suggested better necrotic region repair (p = 0.020), but no femoral head collapse difference in terms of Association Research Circulation Osseous classification change was found (p > 0.05). CONCLUSIONS: A combination of cortico-cancellous iliac bone graft and concurrent vascularized greater trochanter flap with the lateral femoral circumflex transverse branch has been proved can obtain better functional and radiological results than isolate iliac bone grafting, which is attributed to blood reconstruction of the femoral head.

PURPOSE: The purpose of this study is to point out the difficulty of differentiating great trochanter bursitis (GTB) from sciatica and estimating the prevalence of GTΒ, in patients poorly diagnosed with sciatica in their first visit to the general practitioner and referred to a spine infirmary. METHODS: The diagnosis of GTΒ was made based on history and physical examination, and was confirmed by ultrasonography and/or response to an anesthetic plus corticosteroid injection to the trochanteric bursa. Demographic and clinical characteristics of the study group were evaluated. The statistical analysis was held with the SPSS pc package (version 24.0). RESULTS: In a total of 657 referrals for sciatica, 72 patients (10.95%) were incorrectly diagnosed as suffering from sciatica, whereas, in fact, they were suffering from GTΒ. In addition, 18 patients (2.74%) were diagnosed as suffering from persistent sciatica with coexisting GTΒ. More women than men had GTΒ (79-11). Mean age for patients with sciatica diagnosis but suffering from GTΒ was 60 years. Mean age for patients with both sciatica and GTΒ was 61 years. CONCLUSIONS: The GTB is a common clinical entity in middle-aged women, which can escape from the physician in cases of incomplete medical history and clinical examination, leading to unnecessary imaging tests and treatment approaches, burdening both the patient and the health system. Early diagnosis of GTB may dramatically reduce cost, prevent unwanted and inappropriate imaging exams and treatment, and make the patient free of symptoms immediately.

BACKGROUND: Isolated greater trochanter (GT) fractures are relatively rare and few studies have assessed the appropriate diagnostic and therapeutic strategies for these fractures. When initial plain radiographs show an isolated GT fracture, underestimation of occult intertrochanteric extension may result in displacement of a previously non-displaced fracture. This study examined the clinical results and value of different diagnostic strategies in elderly patients with isolated GT fractures on plain radiographs. METHODS: Between January 2010 and January 2015, 30 patients with initial plain radiographs showing isolated GT fractures were examined using MRI, bone scanning and/or CT for suspected occult intertrochanteric extension. We assessed the sensitivity, specificity, and positive and negative predictive value of each test. In addition, we noted the location of the fracture or soft-tissue injury on MRI in addition to treatment results. RESULTS: All 30 patients had osteoporosis and fractures caused by minor trauma. MRI revealed isolated GT fractures in nine patients and occult intertrochanteric fractures in 21 patients. Using the MRI-based diagnosis as a reference, the results showed that plain radiographs, bone scans, and CT scans can be used for supplementary examination but they are not appropriate as confirmatory tests for these fractures. However, in patients with both isolated GT fractures seen on plain radiographs and increased uptake in only the GT area on bone scans, MRI revealed isolated GT fractures. The fractures were treated surgically in 20 patients and conservatively in 10 patients with satisfactory clinical results. CONCLUSIONS: We confirmed that MRI-based examination is useful in all symptomatic elderly patients whose plain radiographic findings reveal isolated GT fractures. However, we suggest that there is a need to establish a diagnostic strategy through increased understanding of the available diagnostic methods. We believe that surgical treatment should be considered in patients with occult intertrochanteric fractures that are detected on MRI.

BACKGROUND: To identify the incidence, contributing factors, and outcomes of perioperative greater trochanter fractures associated with the direct anterior approach. METHODS: This is a retrospective analyses of 1401 primary THAs. Age, side, height, weight, body mass index, preoperative ambulatory status, discharge status, and hospital length of stay were identified. Radiographs were evaluated for femoral neck angle, femoral neck cut ratio (FNCR), and DORR ratio. Bivariate and logistic regression analyses were performed. RESULTS: Thirty-one hips sustained isolated greater trochanter fractures (2.2%). Multivariate analyses identified worse preoperative ambulatory status, diagnosis of slipped capital femoral epiphysis or rheumatoid arthritis, lower FNCR and greater DORR ratio as statistically significant predictors for fracture. Four intraoperative fractures underwent fixation. All postoperative fractures were treated nonoperatively. Thirty fractures healed with 1 nonunion. CONCLUSION: Worse preoperative ambulatory status, diagnosis of slipped capital femoral epiphysis or rheumatoid arthritis, greater DORR ratio, and lower FNCR were associated with increased risk of fracture. Hips with fractures had longer length of stay. Nonoperative treatment was uniformly successful.

Objective: To investigate the reliability of the distance between the tip of the greater trochanter and inter-teardrop line (GT-IT) in evaluating the leg length discrepancy (LLD) in patients underwent total hip arthroplasty (THA). Methods: Patients who underwent THA in Xi'an Honghui Hospital from August 2015 to February 2016 were enrolled in this study.The patients were measured for bilateral hips anterior-posterior (AP) radiograph preoperatively and postoperatively.Four distances measured, included: GT-IT, the tip of lesser trochanter and bi-ischial line (LT-BI); LT-IT and the anterior superior iliac spine and the medial malleolus (ASIS-MM). Magnification factor was considered when calculating absolute values.Intraclass correlation coefficient (ICC) was used to detect the reliability of the measurement data.Single factor analysis and paired t test were performed to compare data among the methods. Results: The ICC values of the four groups were greater than 0.80, which showed excellent agreement in the measurements.Single factor analysis of variance showed there were no statistically significant differences in the LLDs of the four groups preoperatively and postoperatively (F=0.914, 0.886, both P>0.05). There was no significant differences in preoperative and postoperative LLD between group GT-IT and group ASIS-MM, LT-BI or LT-IT(t=-1.544-1.114, all P>0.05). The LLDs were comparable between group LT-BI, ASIS-MM and LT-IT both preoperatively and postoperatively (t=1.577, 0.976, 1.344, -0.087, all P>0.05). And the LLD in group LT-IT and ASIS-MM were equivalent preoperatively and postoperatively (t=0.130, 1.063, both P>0.05). Bland-Altman plot illustrated high level of agreements between the four methods. Conclusion: Great reliability can be obtained with the GT-IT in evaluating the LLD in patients undergoing THA.
