RESUMEN
INTRODUCTION: To investigate the significance of perioperative hepatitis B virus (HBV) DNA changes for predicting recurrence in patients with HBV-related hepatocellular carcinoma (HCC) undergoing liver resection (LR). METHODS: From 2013 to 2020, 241 patients with HBV-related HCC who underwent LR in five Hallym university-affiliated hospitals were enrolled. The serum HBV DNA level, together with other clinicopathological variables, was analyzed for association with HCC recurrence. RESULTS: Preoperatively, 99 patients had undetectable HBV DNA and 142 had detectable viral levels. Of those with detectable viral levels, 72 rapidly progressed to undetectable levels within 3 mo after LR (Rapid group), and 70 showed persistently detectable levels (Nonrapid group). The Rapid group had a better recurrence-free survival (RFS) rate than the Nonrapid group (1-y, 3-y RFS = 75.4%, 57.3%, versus 54.7%, 39.9%, respectively, P = 0.012). In the subgroup analysis, the Rapid group had a better RFS rate in early stages (1-y, 3-y RFS = 82.6%, 68.5%, versus 62.8%, 45.8%, respectively, P = 0.005); however, the RFS rates between the two groups were comparable in the advanced stage (1-y, 3-y RFS = 61.1%, 16.7% versus 45.5%, 22.7%, respectively, P = 0.994). Among the 142 patients with preoperatively detectable HBV DNA, persistently detectable HBV DNA within 3 mo postoperatively (hazard ratio [HR] = 1.7, P = 0.022), large tumor size (HR = 2.7, P < 0.001), multiple tumors (HR = 3.2, P < 0.001), and microvascular invasion (HR = 1.7, P = 0.028) were independent risk factors for RFS in multivariate analysis. CONCLUSIONS: Rapidly undetectable HBV DNA after LR is associated with a better prognosis for recurrence in patients with HCC. Therefore, appropriate treatment and/or screening may be necessary for patients who do not return to undetectable HBV DNA after LR.

INTRODUCTION: Superior and inferior ramus fractures, termed straddle fractures, are high-energy fractures often accompanied by unstable pelvic ring injuries. However, consensus is lacking regarding indications for surgical treatment or fixation methods. We aimed to compare clinical and radiological outcomes of unilateral ramus fixation (URF) and bilateral ramus fixation (BRF) for straddle fractures with unilateral posterior pelvic ring injuries. MATERIALS AND METHODS: We enrolled 118 patients (73 males, 45 females; mean age, 47 years) diagnosed with straddle fractures between March 2015 and December 2021 with > 1 year of follow-up. Patients were divided into URF (n = 60) and BRF (n = 58) groups based on the anterior pelvic ring fixation method. Preoperative factors including body mass index, diabetes, smoking, injury mechanism, injury severity score, American Society of Anesthesiologists classification system, Tile classification, and Young and Burgess classification were compared. Intraoperative blood loss, operation time, postoperative bone union rate, complications, and the need for additional surgeries were analyzed. RESULTS: There were no statistically significant preoperative differences between the two groups. However, the URF group showed a significantly lower mean operative time and blood transfusion requirement (63 min and 2 units, respectively) than the BRF group (104 min and 3 units, respectively) (both p < 0.001). Postoperatively, bone union was achieved in 57 (95.0%) and 56 (96.6%) patients in the URF and BRF groups, respectively. Complications occurred in 17 (28.3%) and 14 (24.1%) patients in the URF and BRF groups, respectively, with additional surgeries needed in 3 (5.0%) patients in the URF group and 2 (3.4%) patients in the BRF group. CONCLUSIONS: Unilateral anterior fixation can provide sufficient stability and clinical effectiveness in the surgical treatment of straddle fractures in areas with posterior pelvic ring injuries. Compared with bilateral anterior fixation, unilateral fixation significantly reduces operation time and blood loss, making it a viable fixation method for straddle fractures.
RESUMEN
BACKGROUND: We investigated the overall clinical outcome of the expanded paratricipital approach in complex articular fractures of the distal humerus and the effect of lack of visualization in the surgical field. In addition, we performed a cadaveric study to investigate the expansion or limitation of articular access in the expanded paratricipital approach. METHODS: Forty-one AO/OTA type 13C fracture cases treated using the expanded paratricipital approach at a single trauma center from 2013 to 2017 were enrolled in this study. We evaluated the overall clinical outcome and analyzed the effect of lack of visualization in the surgical field with the expanded paratricipital approach by comparing outcomes between 2 groups classified by the location of the main articular fracture (group 1, limited visualization; group 2, without limited visualization). The length of inaccessible and accessible articular segments were analyzed using 40 matched-pair elbows. RESULTS: The average duration of follow-up was 15.1 months. All fractures (type C1 in 11 cases, type C2 in 21, and type C3 in 9) were radiologically healed at 3.2 months after surgery. No cases required additional surgery because of implant irritation. The average Mayo Elbow Performance Score was 90.5. The mean Disabilities of the Arm, Shoulder and Hand score was 18.5. Among the 41 cases, the limited visualization group (group 1, n = 21) had a longer surgical time and higher percentage of nonanatomic reduction than group 2. Although the expanded paratricipital approach allowed more articular exposure than the conventional approach, there was still a 20mm inaccessible articular segment (30% of transepicondylar width) in cadaveric dissection. CONCLUSIONS: The expanded paratricipital approach can be used in type C1, type C2, and selective type C3 articular fractures of the distal humerus with favorable results. Relative to surgical times and achieving anatomic reduction, it is more successful in a fracture with a main articular fragment and with good visualization.

PURPOSE: Antibiotics are widely used in the treatment of uncomplicated left-sided colonic diverticulitis. In Asian countries, however, right-sided colonic diverticulitis is more common than left-sided colonic diverticulitis. The aim of the present study was to evaluate the need for antibiotics in the treatment of uncomplicated right-sided colonic diverticulitis in an Asian population. METHODS: Patients were randomized to two management strategies: antibiotics and no antibiotics. At 4-6 weeks after discharge, the patients in both groups underwent computed tomography or were contacted by phone to confirm the effectiveness of the treatment. The primary end point was the treatment failure rate of the initial treatment, and secondary end points were the length of hospital stay and total admission costs. RESULTS: Patients were randomized to treatment with (61 patients) or without (64 patients) antibiotics. The rates of treatment failure in the antibiotics and no antibiotics groups were 1.7% and 4.6%, respectively, with no significant difference (P = 0.619). There was also no significant difference in the length of hospital stay between the groups (P = 0.983). Total admission costs were lower in the no antibiotics group than in the antibiotics group (US$1004.70 vs US$1112.40, respectively, P = 0.037). CONCLUSION: Conservative management of uncomplicated right-sided colonic diverticulitis without antibiotics shows similar treatment failure rates and length of hospital stay, and is associated with lower hospital costs, compared with standard antibiotic treatment. Therefore, conservative management can be considered as a safe treatment option. TRIAL REGISTRATION: ClinicalTrial.gov No. NCT02314013.

PURPOSE: The purposes of the study were to introduce surgical technique of fragment-specific fixation technique using multiple 2.7-mm variable-angle locking compression plates (VA LCPs) in comminuted posterior wall acetabular fractures and reported its clinical results. PATIENTS AND METHODS: Among the 68 patients, 23 with comminuted posterior wall factures with ≥ 3 fragments in the CT scan and no column involvement with a minimum follow-up duration of 12 months were enrolled in this study. We evaluated the clinical results after the treatment of comminuted posterior wall acetabular fractures via the fragment-specific fixation technique using 2.7-mm variable-angle locking compression plates (VA LCPs) retrospectively. RESULTS: The average duration of follow-up was 26.8 months. Anatomical reduction was achieved in eighteen patients. Imperfect reduction was achieved in five patients. 22 patients achieved fracture union and one patient underwent revision surgery owing to acute postoperative infection. There were no complications, including loss of reduction, fixative failures, sciatic nerve palsy, heterotopic ossification, and early posttraumatic arthritis among 22 patients. The average functional outcome was measured as 'very good'. CONCLUSION: Fragment-specific fixation technique using 2.7-mm VA LCPs for comminuted posterior wall acetabular fractures could be an acceptable alternative means of surgical fixation.

INTRODUCTION: We present the surgical technique of rim-plate-augmented separate vertical wiring for comminuted inferior pole fracture of the patella and report the clinical outcomes. MATERIALS AND METHODS: Between July 2013 and January 2016, 13 patients (7 male and 6 female) who were diagnosed with comminuted inferior pole fracture of the patella in preoperative computed tomography and underwent a minimum of 1 year of follow-up were enrolled in this study. Mean patient age was 57.7 years (range 28-72 years). All patients underwent open reduction and internal fixation by rim-plate-augmented separate vertical wiring. Bony union, complications, range of motion and Bostman score were the clinical outcomes. RESULTS: Bony union was achieved in all cases at an average of 10 weeks after surgery (range 8-12). There was no loss of reduction and fixative failure during follow-up. The average range of motion was 127° (range 120°-130°). The mean Bostman score at last follow-up was 29.6 points (range 27-30) and graded excellent in 12 patients. CONCLUSION: Rim-plate-augmented separate vertical wiring demonstrated secure fixation and favorable clinical outcomes. This study provides evidence for its effectiveness as a fixation method for treating displaced, comminuted inferior pole fracture of the patella.

PURPOSE: To review available approaches and fixation methods for posterolateral fracture fragment (PLF) in tibial plateau fracture, and to propose an algorithm to treat various types of plateau fractures which all involve the PLF. METHODS: This article reviews multiple surgical approaches for PLF and suggests an algorithm for suitable approach and fixation method according to PLF with combined plateau fracture. RESULTS: The modified anterolateral approach is a suitable single approach for fractures with a PLF combined with an anterolateral plateau fracture and for isolated posterolateral fracture fragments. For a multicolumn tibia plateau fracture involving the lateral, medial and posterior columns, dual approaches (modified anterolateral and posteromedial approach) can be used to access the entire plateau area. CONCLUSIONS: When considering approaches of this complex fracture pattern, one must consider local soft tissue condition, plateau fracture morphology, associated injuries, and fixation options. After review of multiple approaches described in the literature for PLF fixation, we can suggest an algorithm for the approach and fixation to treat tibial plateau fractures with posterolateral fracture fragments.

A3 intertrochanteric fracture has a higher incidence of intraoperative re-displacement than A1 and 2. The authors have also experienced difficulty with maintenance of reduction in A3 intertrochanteric fractures, as the technique depends on manual effort and can fail easily during the procedure. It induced us to develop this surgical technique to ease the surgical procedure and improve clinical outcomes. This paper introduces a modified provisional guide pin fixation technique applicable to even AO/OTA A3 intertrochanteric fractures, and presents preliminary results of 11 patients who were treated by provisional pin fixation-assisted nailing in A3 intertrochanteric fractures. Using this technique, we have reduced the chances of intraoperative reduction loss and achieved favorable clinical outcomes.

INTRODUCTION: During nailing of intertrochanteric fractures, there is always a risk of reduction loss despite achieving an acceptable reduction status after a percutaneous procedure. Most surgeons usually attempted to maintain the reduction with a manual endeavor. However, we experienced varying amounts of intraoperative reduction loss and had to perform readjustments several times. These struggles motivated us to attempt provisional pin fixation as an alternative method. The purpose of this study was to analyze the factors affecting intraoperative reduction loss, especially in comparison between two methods. MATERIALS AND METHODS: Sixty-eight patients with intertrochanteric fractures were included. They were divided into two groups based on the method, by retrospective analysis of the intraoperative c-arm image. In the manual maintenance group, an assistant maintained the instruments during the procedure. In the provisional pin fixation group, the reduction was temporaryily held by a 3.2mm guide pin fixation across the fracture. A displacement of more than one cortical thickness in any plane or angular deformity during any point in the procedure after acceptable reduction was judged as an intraoperative reduction loss. Multivariate logistic regression was used for statistical analysis. RESULTS: The number of cases with intraoperative reduction loss was 18 (18 of 38, 46.1%) in the manual maintenance group and 6 (6 of 30, 20.0%) in the provisional pin fixation group. The odds ratio of intraoperative reduction loss in the manual maintenance group was 5.182 (95% confidence interval, 1.455-18.452) compared with the provisional pin fixation group as the reference. CONCLUSIONS: As a reasonable approach for maintaining reduction, provisional pin fixation can significantly decrease intraoperative reduction loss after percutaneous reduction of intertrochanteric fractures during nailing.

PURPOSE: Premature physeal closure of the proximal femoral physis has been reported in Legg-Calve-Perthes Disease (LCPD). However, the timing of its occurrence had not yet been reported. We proposed (1) to determine the timing of premature physeal closure in unilateral LCPD with serial radiographic evaluation, and (2) to evaluate the relationship between the premature physeal closure and Herring classification, leg-length discrepancy (LLD), Stulberg classification, and trochanteric overgrowth. METHODS: We performed a retrospective study with serial radiographs of 27 patients diagnosed with LCPD. The difference in the timing of physeal closure between the hips was calculated. The involved hip was classified according to Herring classification. The LLD and ATD index at latest follow up was measured. The mean values were calculated and statistical comparison of variables was done using the Fisher's exact test. RESULTS: The mean difference of physeal closure at the involved hip compared to the uninvolved side was 3.5 years (range, two to five years). Hips demonstrating premature physeal closure were associated with Herring B/C and C (p = 0.01) and LLD >1 cm (p = 0.02). There is no correlation between Stulberg classification, trochanteric overgrowth and premature physeal closure (p = 0.06 and p = 0.19). CONCLUSIONS: We may expect premature physeal closure of the proximal femoral physis in patients with LCPD to occur 3.5 years earlier than normal hips. Presence of premature physeal closure can be an adjunct diagnostic tool in the prognostication of LCPD outcomes. Future studies directed toward premature physeal closure in LCPD and associated growth disturbances are necessary.

This study retrospectively assessed radiographic outcomes and risk factors associated with non-union in femoral shaft fragmentary segmental fractures (AO/OTA 32C3) treated with reamed antegrade intra-medullary nailing. Radiological outcomes, including union and alignment, were evaluated. The risk factors for non-union were investigated, including demographics and treatment-related characteristics, such as the number of interlocking screws, segmentation length, main third fragment length, distance of the main third fragment, width ratio and exposed nail length in one cortex from immediate post-operative radiographs. Multivariate logistic regression was used for statistical analysis. Among 2295 femoral shaft fracture patients from three level-1 trauma centers, 51 met the inclusion criteria. The radiological union was achieved in 37 patients (73%) with a mean union time of 10.7 ± 4.8 months. The acceptable axial alignment was observed in 30 patients (59%). Multiple logistic regression analysis identified only exposed nail length as a significant risk factor for non-union (odds ratio: 1.599, p = 0.003) and the cut-off value was 19.1 mm (sensitivity, 0.786; specificity, 0.811). The study revealed high rates of non-union (27%) and malalignment (41%). Therefore, patients who underwent intramedullary nailing with an exposed nail length greater than 19.1 mm or about twice the nail diameter should be cautioned of the potential non-union.

INTRODUCTION: Recombinant human Bone morphogenetic proteins have been used for the treatment of nonunions with promising results. We have been investigating both experimentally and clinically the efficacy of the rhBMP-2 with the macro / micro-porous hydroxyapatite carrier granules on the potency on the reconstruction of long bone defect. The purpose of this study was to prospectively evaluate the efficacy and safety of this specific rhBMP-2 with HA carrier granules mixed with autologous cancellous bone in patients with nonunion and bone defect resulted from the fracture related infection. MATERIALS AND METHODS: This was a retrospective review of a prospective cohort at a university hospital. Patients diagnosed with nonunion under the definition of the United States Food and Drug Administration with bone defect after long bone fractures were enrolled from January 2020 to February 2021. We included patients with atrophic and oligotrophic nonunion, and hypertrophic nonunion with malalignment that needed to be corrected. The other patient group was consisted of segmental bone defect resulted from FRI. The maximum amount of rhBMP-2 allowed in this clinical study was 6 mg and was added to autologous bone at a 1:1 ratio. Autologous bone was added to the mixture if the volume of mixed graft was insufficient to fill the bone defect. Patients were followed 3, 6, and 12 months post-operatively. Each visit, a radiograph was taken for assessment. Visual analog scale (VAS), questionnaire for quality of life (SF-12 physical component summary [PCS], mental component summary [MCS]), and weight-bearing status were collected for functional outcome assessment. Drug safety was assessed by examining BMP-2 antibodies. RESULTS: Of the 24 enrolled patients (mean age: 57 years), 15 (62.5 %), 2 (8.33 %), and 7 (29.17 %) presented atrophic nonunion, hypertrophic nonunion with deformity, and bone defect after fracture related infection, respectively. Thirteen patients had nonunion in the femur, 9 in the tibia, and 1 in the humerus and radius. The average amount of harvested autologous bone was 9.25 g and 4.96 mg of rhBMP-2. All 24 patients achieved union after 1-year follow up. The union rate was 95.83 % and 100 % at 6 and 12 months postoperatively, respectively. Preoperative SF-12 PCS (mean: 34.71) improved at 6 and 12 months postoperatively, respectively. Preoperative SF-12 MCS (mean: 42.89) improved 12 months postoperatively (49.13, p = 0.0338). Change of VAS was statistically significant 3 months postoperatively (p = 0.0012). No adverse effects or development of BMP-2 antibodies were observed. CONCLUSION: BMP-2 combined with autogenous bone resulted in excellent radiographical and functional outcomes in a relatively small prospective series of patients with nonunion and bone defect, without adverse effects. Further investigations are necessary to support our finding and optimize treatment strategies in nonunion patients.
RESUMEN
Osteochondromas are very common benign tumors composed of cartilage and bone. They are usually found at the end of the growth plate of long bones, most often at the area of the joints, and are contiguous with the medullary cavity. Extraskeletal osteochondromas, the same as their namesake, are composed of cartilage and bone. However, unlike typical osteochondromas, extraskeletal osteochondromas are not contiguous with bone, as their name implies. They usually arise from the synovial tissue and tendon sheaths. Although rare, extraskeletal osteochondromas have been reported to occur within the knee and around the hip; however, they are more commonly reported to occur in the hands and feet. When found in the hands or feet, these new growths are often very small and only occasionally symptomatic. We present the case of a 49-year-old female who had a slow-growing mass of 4 years' duration, located on the plantar aspect of her left foot. The mass was slowly becoming more palpable as it increased in size and was progressively causing pain and discomfort during ambulation. Imaging studies revealed an ossified mass bearing no connection to any other structure on the plantar aspect of her foot. An excision biopsy was performed, and the easily dissectible mass, although much larger than its usual presentation, proved to be an extraskeletal osteochondroma.

Background: Vitamin D concentrations are associated with sepsis, pneumonia, and mortality in critically ill patients. However, the role of vitamin D in critically injured patients with trauma remains unknown. This study investigated the effects of vitamin D concentrations on outcomes in critically injured patients with trauma. Methods: A prospective observational study was conducted by randomly selecting 100 patients among those who visited our trauma center. The serum vitamin D concentration was measured upon arrival at the hospital, and the length of stay in a trauma intensive care unit after admission, duration of mechanical ventilation, number of days spent in the hospital, development of complications, and death were investigated. The association between the surveyed variables and vitamin D concentrations was investigated using regression analysis. Results: Of the 100 patients, 69 were men and 31 were women with an average age of 51.7 years. The average intensive care unit stay length was 18.4 days, and 6 patients (5.9%) died. Univariate regression analysis showed that the factors affecting patient mortality were age (p = 0.02), volume of blood transfused within 24 hours of arrival (p = 0.009), systolic blood pressure measured upon hospital arrival (p = 0.01), and serum lactate concentration measured upon hospital arrival (p = 0.03). Multivariate regression analysis showed that the factors affecting patient mortality were age (p = 0.01), volume of blood transfusion (p = 0.04), and systolic blood pressure measured upon hospital arrival (p = 0.01). Conclusions: There were no statistically significant effects of serum vitamin D concentrations in critically ill patients with trauma on death during hospitalization.

INTRODUCTION: Open pelvic fractures are commonly associated with life-threatening, uncontrollable haemorrhages. Although management methods for pelvic injury-associated haemorrhage have been established, the early mortality rate associated with open pelvic fractures remains high. This study aimed to identify predictors of mortality and effective treatment methods for open pelvic fractures. METHODS: We defined open pelvic fractures as pelvic fractures with an open wound directly connected to the adjacent soft tissue, genitals, perineum, or anorectal structures, resulting in soft tissue injuries. This study was performed on trauma patients (age ≥15 years) injured by a blunt mechanism between 2011 and 2021 at a single trauma centre. We collected and analysed the data on the Injury Severity Score (ISS), the Revised Trauma Score (RTS), the Trauma and Injury Severity Score (TRISS), length of hospital stay, length of intensive care unit stay, transfusion, preperitoneal pelvic packing (PPP), resuscitative endovascular balloon occlusion of the aorta (REBOA), therapeutic angio-embolisation, laparotomy, faecal diversion, and mortality. RESULTS: Forty-seven patients with blunt open pelvic fractures were included. The median age was 45 years (interquartile range, 27-57 years) and median ISS was 34 (24-43). The most frequently performed treatment methods were laparotomy (53%) and pelvic binder (53%), followed by faecal diversion (40%) and PPP (38%). PPP was the only method performed at a higher rate in the survival group for haemorrhagic control (41% vs. 30%). Haemorrhagic mortality was present in one case that received PPP. The overall mortality was 21%. In the univariate logistic regression analysis, initial systolic blood pressure (SBP), TRISS, RTS, packed red blood cell transfusion for the first 24 h, and base excess showed statistical significance (p<0.05). In the multivariate logistic regression model, initial SBP was identified as an independent risk factor for mortality (odds ratio, 0.943; 95% confidence interval, 0.907-0.980; p = 0.003). CONCLUSION: A low initial SPB may be an independent predictor of mortality in patients with open pelvic fractures. Our findings suggest that PPP might be a feasible method to decrease haemorrhagic mortality from open pelvic fractures, especially for haemodynamically unstable patients with low initial SBP. Further studies are required to validate these clinical findings.

Despite the variety of treatment methods, comminuted inferior pole fractures of the patella remain difficult and technically demanding to achieve stable internal fixation. The purpose of this study is to evaluate the clinical outcomes of rim plate-augmented separate vertical wiring with supplementary fixation in the management of comminuted inferior pole fractures, AO/OTA 34-A1, C2, and C3, which has the secondary horizontal fracture line on lower articular boundary. From our study, bony union was achieved in all patients at an average of 3.1 ± 1.4 months after surgery. There was no patient with loss of reduction, fixation failure, or infection during follow-up. The average final range of motion was 131.6° ± 7.2°. Lysholm knee scores gradually increased over 3, 6, 9, and 12 months postoperatively by 58.7, 74.0, 82.9, and 89.4, respectively. Isokinetic peak torque deficit of the knee extensor muscles in 3, 6, 9, and 12 months postoperatively was 59.9%, 49.7%, 35.7%, and 28.1%, respectively. The rim plate-augmented separate vertical wiring with supplementary fixation for the treatment of patellar fracture associated comminuted inferior pole is effective and can be safely applied AO/OTA 34-C2 or C3 with favorable outcomes.

PURPOSE: This study aims to evaluate the effect of different pneumoperitoneum pressures on postoperative pain, especially by subcategorizing the pressures into 3 groups during laparoscopic cholecystectomy (LC). METHODS: We conducted a prospective randomized, double-blinded study of 150 patients with benign and uncomplicated gallbladder disease. They were categorized into 3 groups. Each group (50 patients) underwent LC with different pneumoperitoneum methods: group VLP, very-low pressure (6-8 mmHg); group LP, low pressure (9-11 mmHg); and group SP, standard pressure (12-14 mmHg). The 3 groups were compared for pain intensity, duration, analgesic requirement, and complications. RESULTS: The characteristics of the patients were similar among all groups. Postoperative pain scores at each time point (1, 2, 4, 6, 12, 24, and 48 hours) were not significantly different among the 3 groups. Further, operation time, hospital stay, the number of analgesic consumption doses, and postoperative complications were not significantly different among the 3 groups. CONCLUSION: This study demonstrates no difference in postoperative pain among various pneumoperitoneum pressures during LC. Therefore, routine use of lower-pressure pneumoperitoneum is not recommended unless in selected patients who require low-pressure pneumoperitoneum surgery.
RESUMEN
The incidence of intertrochanteric femoral fractures has rapidly increased with the extended lifespan of the elderly population. Surgery enables early ambulation by achieving anatomic reduction and stable internal fixation. However, reduction usually involves postoperative evaluation. Here, we present reliable parameters obtained from analyses of three-dimensional computed tomography images from cadavers to serve as guidelines during the reduction of intertrochanteric fractures. We included 184 three-dimensional modeling samples from cadavers placed in two standardized positions, similar to C-arm imaging. We recorded the level of the orthogonal line from the greater trochanter (GT) tip to the femoral head (GT orthogonal line [GTOL]) in the anteroposterior view and the line along the anterior femoral cortex passing through the femoral head (anterior cortical line) in the axial view. Correlations between these lines and angular alignments were statistically determined. The GTOL passed above the femoral head center at mean 2.36 mm in all patients; 77.17% of such instances were in the upper second quadrant of the femoral head. The anterior cortical line passed under the femoral head center at mean 10.82 mm; 73.37% of such instances were in the inferior one-third of the femoral head. Consistent correlations were found between the GTOL and neck-shaft angle and between the anterior cortical line and anteversion. The GTOL and anterior cortical line passed through a constant level of the femoral head in most samples and were correlated with angular alignments. The intraoperative use of these simple imaginary lines improves the intertrochanteric fracture reduction quality.
