MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1987. [PMID: 38004036 PMCID: PMC10673107 DOI: 10.3390/medicina59111987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/02/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: Patients with occult hip fractures are a difficult subgroup to treat. MRI is the gold standard for diagnosing occult proximal femur fractures but is costly and may not be readily available in an emergency setting. The purpose of this study was to determine whether changes in the proximal femur geometry can predict the likelihood of an occult hip fracture in patients presenting with hip pain following a ground-level fall. Material and Methods: Patients admitted to the hospital with a clinical suspicion of a hip fracture but initial negative radiographs over a seven-year period were included. All patients were additionally investigated with an MRI scan, and retrospectively, six radiologic parameters were obtained on plain radiographs: The cortical thickness index (CTI), the canal to calcar ratio (CCR), the canal flare index (CFI), the morphological cortical index (MCI), the canal bone ratio (CBR) and the canal bone aria ratio (CBAR). Subsequently the result of the plain radiographic indices of the patients with a negative MRI (Group A, no occult fracture) were compared to those with a positive MRI (Group B, occult fracture). Results: A total of 78 patients (59 female, 19 male) could be included in the study. The mean age was 82 years. The univariate analyses revealed a poor predictive ability of all radiological parameters with AUC values ranging from 0.515 (CBR) to 0.626 (CTI), whereas a multivariate prognostic model demonstrated improved prognosis (AUC = 0.761) for the CTI (p = 0.024), CBAR (p = 0.074) and CRR (p = 0.081) as the most promising predictive radiological parameters. Conclusions: Single radiologic indices obtained from conventional X-rays of the proximal femur have a weak predictive value in detecting occult fractures of the hip and cannot be used as clinical decision-making factors.

Abstract
Radiofrequency echographic multi-spectrometry (REMS) is an ultrasound technique that has been recently introduced in the medical field to detect osteoporosis and fracture risk at axial sites. The use of sonography to visualize the region of interest (ROI) of the hip neck provides the opportunity to identify occult fractures. A 91-year-old woman with persistent right leg pain was referred to rheumatologist due to a known history of arthritis and osteoporosis. She was able to walk using a crutch, although experiencing an antalgic gait. The patient had recently fallen on her right side from standing height. During the visualization of the ROI of the right femoral neck using REMS, an abrupt break of the femoral cortex suspected to be a fracture was seen; therefore, the measurement of the femoral neck was performed on the left side. The T-score had value of -2.9 SD and the fragility score was 86.7. Due to unclear signs of a fracture after an X-ray of the hip, a computed tomography (CT) exam of the hip was performed, which revealed a femoral neck fracture. Occult fractures of the femoral neck are challenging to diagnose and require numerous radiologic exams. The use of ultrasound as a method to measure bone density allows the simultaneous diagnosis of osteoporosis and detection of fractures.

Abstract
Acute hip pain following injury more commonly originates locally in and around the hip joint rather than being referred from the lumbar spine, sacroiliac joints, groin, or pelvis. Clinical assessment can usually localize the pain source to the hip region. Thereafter, imaging helps define the precise cause of acute hip pain. This review discusses the imaging of common causes of acute hip pain following injury in adults, addressing injuries in and around the hip joint. Pediatric and postsurgical causes of hip pain following injury are not discussed.

Abstract
Pertrochanteric fractures (PFs) in the elderly and their consequences are among the leading causes of disability; they significantly reduce the quality of life and lead to loss of independence. This article aims to determine the functional and radiological outcomes in a group of patients with PFs treated with either the Dynamic hip screw (DHS) or intramedullary Gamma nail fixation. A total of 618 patients, admitted to hospital for pertrochanteric fractures between 2015 and 2019, at a mean age of 82.40 (range 29–104) were screened. Finally, 78 patients were enrolled. Parameters related to hospital stay and surgery (length of hospital stay, surgery duration) were compared in both groups. Functional outcomes were assessed by the Harris hip score, subjective pain was measured with a visual analogue scale (VAS), and quality of life was evaluated using the EQ-5D-5L questionnaire. The obtained results were evaluated at 3- and 6-month follow-up. Radiographic parameters were measured based on the preoperative and postoperative standing anterior–posterior pelvic radiographs and axial projection of the hip at 6-month follow-up. The results showed no significant difference between groups treated either with DHS or intramedullary Gamma nail fixation within the scope of the variables under study. In conclusion, both analysed methods support the functional symmetry of the musculoskeletal system.

Abstract
Introduction The Throckmorton sign, or John Thomas sign, is a well-established orthopedic eponym, anecdotally used in orthopedic surgery to correlate the direction of male genitalia, observed on a pelvic radiograph, with the laterality of an associated orthopedic pathology. In earlier studies, the direction of pelvic shadowing on X-ray has been neither a credible nor a reliable predictor of fracture laterality. Given this small body of evidence, we sought to further investigate the relationship between peri-trochanteric hip fracture laterality and male genitalia lie. Method A single-center retrospective chart review was conducted of 397 consecutive male patients who received pelvic radiographs performed upon entry to an urban level 1 trauma center. Exclusion criteria included age less than 18 years or a prior history of pelvic or urological surgery. Of this cohort, 360 patients met the inclusion criteria and underwent investigation. Results The study population had an average age of 42 years (range: 18-91 years). Statistical analysis yielded a 4.24 relative risk with pelvic shadowing laterality and respective peri-trochanteric hip fracture sidedness. Additionally, there was a 4.63 and 9.88 relative risk of tibial shaft fractures and distal radius fractures having a concomitant positive Throckmorton Sign, respectively. Conclusion Pelvic shadowing can be used as an additional diagnostic tool in predicting peri-trochanteric hip fracture sidedness in a trauma bay setting.

Abstract
This study aimed to develop a method for detection of femoral neck fracture (FNF) including displaced and non-displaced fractures using convolutional neural network (CNN) with plain X-ray and to validate its use across hospitals through internal and external validation sets. This is a retrospective study using hip and pelvic anteroposterior films for training and detecting femoral neck fracture through residual neural network (ResNet) 18 with convolutional block attention module (CBAM) + + . The study was performed at two tertiary hospitals between February and May 2020 and used data from January 2005 to December 2018. Our primary outcome was favorable performance for diagnosis of femoral neck fracture from negative studies in our dataset. We described the outcomes as area under the receiver operating characteristic curve (AUC), accuracy, Youden index, sensitivity, and specificity. A total of 4,189 images that contained 1,109 positive images (332 non-displaced and 777 displaced) and 3,080 negative images were collected from two hospitals. The test values after training with one hospital dataset were 0.999 AUC, 0.986 accuracy, 0.960 Youden index, and 0.966 sensitivity, and 0.993 specificity. Values of external validation with the other hospital dataset were 0.977, 0.971, 0.920, 0.939, and 0.982, respectively. Values of merged hospital datasets were 0.987, 0.983, 0.960, 0.973, and 0.987, respectively. A CNN algorithm for FNF detection in both displaced and non-displaced fractures using plain X-rays could be used in other hospitals to screen for FNF after training with images from the hospital of interest.

Abstract
PURPOSE A focused hip MRI (FHMR) for the detection of radiographically occult hip fractures was implemented in our emergency department (ED) in 2013. The goal of this study was to assess the clinical utility of this protocol. METHODS We retrospectively reviewed radiology reports of 262 unique patients who underwent 263 FHMR (coronal T1, coronal STIR, axial T2 fat saturated) for suspected hip fracture in the ED from October 2013 to March 2020. Electronic medical records were reviewed for the ED course, follow-up imaging, and clinical management within 90 days. RESULTS Seventy-one patients had one or more fractures identified by FHMR: one-third had proximal femoral fractures; two-third had pelvic fractures. Of these 71 patients, 53 (74%) had radiographically occult fractures, including 14 (20%) with occult proximal femoral fractures; 4 patients had fractures occult on CT. Nineteen patients with a suspected fracture on radiography were found to have no fracture on FHMR. Four fractures not reported on FHMR were later seen on follow-up imaging: these included 1 isolated greater trochanter, 1 additional ischial tuberosity, 1 additional superior pubic ramus, and 1 additional sacrum. All four fractures were treated non-operatively. Muscle/tendon injury was the most common type of injury, seen in 50% (130/262) patients with the most commonly torn tendons being the hamstring (44%; 15/34) followed by gluteus medius tendon (18%; 6/34). A full-hip or pelvis MRI was done after FHMR in only 5 patients, primarily for the purpose of better characterizing findings already identified on FHMR (2 for fracture, 2 for tendon injury, 1 for soft tissue metastasis). Only one of these five studies provided new information: ruling out a previously questioned fracture. Clinical management of the vast majority of patients was based solely on findings from the FHMR. CONCLUSIONS FHMR offers reliable identification of radiographically occult hip fractures and muscle/tendon injuries. The protocol is well trusted in guiding patient management in our ED.

Abstract
The cortical shell of the femoral neck plays a role in determining the overall neck strength. However, there is a lack of knowledge about the mechanical properties of cortical tissue of the femoral neck due to challenges in implementing accurate testing protocols for the thin shell. Indeed, mechanical properties are commonly derived from mechanical testing performed on tissue samples extracted from the femoral diaphysis, i.e. assuming tissue homogeneity along the femur. The aim of this work was to set up a reliable methodology to determine mechanical properties of bone samples extracted from thin cortical shell of the femoral neck. A three-point bending test was used to determine elastic and post-elastic properties of cortical bone samples extracted from the inferior and superior femoral neck. An optical system was used to monitor the sample deflection. Accuracy was preliminarily evaluated by determining the elastic modulus of an aluminium alloy. A good intra- and inter-sample variability was found on determining aluminium elastic modulus: 1.6% and 3.6%, respectively. Additionally, aluminium elastic modulus value was underestimated by less than 1%. A pilot trial was performed on a human femoral neck to assess the procedure feasibility. A total of 22 samples were extracted from the inferior and superior femoral neck and successfully tested. Preliminary results suggest that mechanical properties of cortical bone tissue extracted from human femoral neck might be side dependent, the superior tissue seems to exhibit better mechanical properties than the inferior one, at least in terms of yield stress and maximum strain. This supposedly different mechanical competence must be further investigated. The proposed procedure makes it feasible to carry out such studies.

Abstract
CASE A 53-year-old woman presented to the emergency department with persistent left hip pain after a fall while riding a bicycle. Although x-ray imaging revealed no evidence of fracture, an abnormal intensity vertical line along the left femoral neck was observed in the magnetic resonance imaging (MRI). Furthermore, 2 weeks after injury, MRI revealed a newly developed abnormal intensity oblique band at the femoral neck. After discussing several treatment options with the patients, she chose the conservative treatment. CONCLUSION Careful follow-ups and MRI were undertaken 6 times within 32 weeks. Bone union was observed 32 weeks after the injury, and no bone displacement was observed.

Abstract
To perform a systematic review (SR) and meta-analysis to determine the diagnostic test accuracy (DTA) of Multi-Detector Computed Tomography (MDCT) for detecting proximal femoral (hip) fragility fractures in patients with a negative initial radiograph. MEDLINE and EMBASE were searched to identify relevant studies published between January 2000 and May 2018. Articles underwent title and abstract screening followed by full-text screening. Study inclusion criteria are patients with suspected hip fracture, negative initial radiograph, MDCT as the index test, magnetic resonance imaging (MRI) or clinical follow-up as the reference standard, and DTA measure as the outcome. Demographic, methodologic, and study outcome data were extracted. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. DTA metrics were pooled using bivariate random-effects meta-analysis. From an initial 1385 studies, four studies reporting on 418 patients (174 with hip fractures) were included. Pooled summary statistics included the following: sensitivity (87%; 95% confidence interval [CI] 79-93), specificity (98%; 95% CI 95-99), and the area under the summary receiver operating characteristic (ROC) curve (0.972). MDCT has a high specificity for detecting hip fragility fractures, comparable to MRI, but a lower sensitivity. Local institutional factors may play a role in whether a patient receives MDCT or MRI, as imaging should not be delayed. If there is ongoing concern for fracture in a patient with a negative MDCT, MRI should be performed. Cautious interpretation of the results is warranted given the risk of bias and small sample size.

Abstract
OBJECTIVE Perform translation, cultural adaptation and psychometric testing of the Romanian translation of the Hip disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS_JR). DESIGN Assess construct validity, reliability, internal consistency and reproducibility. SETTING Adults with chronic hip disability prior or at a minimum of 3 months after surgery. PARTICIPANTS Ninety-six patients (22 bilateral) with hip osteoarthritis or who had previous hip replacement or osteosynthesis for a fracture of the trochanteric region. INTERVENTION Complete the HOOS_JR together with the Oxford Hip Score (OHS_RO), Harris Hip Score (HHS) and Euroqol EQ-5D. 57 patients repeated the HOOS_JR after 2 days. MAIN OUTCOME MEASURE Convergent validity using Spearmans's correlation coefficient; Cronbach's alpha coefficient, intraclass correlation coefficient (ICC, two-way mixed effects model) and inter-item correlation matrix and test-retest assessment after 2 days. RESULTS The questionnaire had a high degree of reliability with a Cronbach's α of 0.923 at the initial completion and 0.924 at the second testing. The ICC was 0.923 for average measures for the first form and 0.910 for the second form. The two results were strongly, positively and significantly correlated (rs = 0.859; P < 0.001). The Romanian HOOS_JR strongly, significantly and positively correlated with the OHS_RO (rs = -0.880 initial and rs = -0.803 s; P < 0.001) and HHS (rs = -0.731 initial and rs = -0.654 s; P < 0.001) and moderately, significantly and positively correlated with the EQ-5D Index (rs = -0.580 initial and rs = -0.542 s; P < 0.001) and VAS (rs = -0.500 initial and rs = -0.690 s; P < 0.001). CONCLUSIONS The translated HOOS_JR is a reliable, reproducible and valid measure of function in patients with chronic hip disability.

[PMID: 30899712 PMCID: PMC6414406 DOI: 10.5371/hp.2019.31.1.23] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 12/17/2018] [Accepted: 12/20/2018] [Indexed: 12/04/2022] Open
Abstract
Purpose Isolated greater trochanteric (GT) fractures are often identified using plain radiography of patients with post-traumatic hip pain. In many cases, the fracture extends to form an occult intertrochanteric fracture. We conducted a study to determine the frequency of occult intertrochanteric fractures in patients diagnosed with isolated GT fractures using plain radiographs. Materials and Methods Among 3,017 individuals who visited our emergency department with a trauma-induced pertrochanteric femur fracture between July 2004 and March 2018, 100 patients diagnosed with isolated GT fractures using plain radiographs were retrospectively analyzed. Patients were divided into two groups, those with: i) isolated GT fractures (group A) and ii) occult intertrochanteric fractures (group B). In addition, plain radiographs, magnetic resonance imaging results, and treatment methods were further analyzed in each group. If surgery treatment was needed, it was performed by one surgeon, and in all cases, a 2-hole dynamic hip screw was used. Results Among the 100 cases of isolated GT fractures diagnosed using plain radiograph, additional examinations revealed that 10 (10.0%) were suffering from isolated GT fractures alone, while the remaining 90 (90.0%) were further diagnosed with occult intertrochanteric fracture. Gender, age, mechanism of injury, and bone mineral density did not correlate with fracture type. Conclusion In our analysis, 90% of injuries initially diagnosed as isolated GT fractures were found to extend into occult intertrochanteric fractures upon further examination with additional imaging modalities. Therefore, additional evaluation should be performed to test for the potential presence of occult intertrochanteric fractures and to establish appropriate treatment plans.

Haematology panel biomarkers for humeral, femoral, and tibial diaphyseal fractures. INTERNATIONAL ORTHOPAEDICS 2019; 43:1567-1572. [PMID: 30729272 DOI: 10.1007/s00264-019-04305-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Accepted: 01/21/2019] [Indexed: 12/22/2022]
Abstract
PURPOSE The neutrophil to lymphocyte ratio (NLR) is a simple predictor used in oncology and cardiology. We aimed to analyze the NLR profile of patients with diaphyseal fractures of the humerus, femur, and tibia. METHODS We performed a cross-sectional, consecutive-case population-based study including 148 patients (41.9% men respectively 58.1% women) with humeral (23.0%), femoral (30.4%), and tibial (46.6%) diaphyseal fractures, admitted for surgical treatment in our level 1 trauma centre over two years. RESULTS The differences in NLR between the studied subgroups were not significant (p = 0.067), the highest value being observed in patients with femoral fracture (5.6) in contrast to patients with humeral fracture (4). In the global cohort, there was a significantly positive correlation between NLR and PLR (platelet to lymphocyte ratio; Spearman's r = 0.595; p < 0.001). The stratified subgroup analysis found significant association between NLR and duration of admission only for patients with femoral fracture (Spearman's r = - 0.308; p < 0.001). When compared with controls, all three fracture types had significantly higher neutrophil numbers and NLR and lower thrombocyte numbers. CONCLUSIONS NLR are elevated in femur diaphyseal fractures compared with tibia and humerus, up to cut-off values with negative prediction of outcome in malignancy and cardiovascular patients. Increased NLR are predictive of longer hospital admissions for femur fractures.

Geriatr Orthop Surg Rehabil 2019; 10:2151459318821214. [PMID: 30719399 PMCID: PMC6348569 DOI: 10.1177/2151459318821214] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Accepted: 11/26/2018] [Indexed: 11/20/2022] Open
Abstract
Introduction: The National Institute of Health and Clinical Excellence guidelines in the United Kingdom recommend magnetic resonance imaging (MRI) as the first-line investigation for radiographically occult hip fractures, if available within 24 hours. In our department, however, multislice computerized tomography (MSCT) is instead used as a first-line investigation due to significant delays associated with obtaining MRI. Our aim was to determine the validity and practicality of MSCT for diagnosis of occult hip fractures and its impact on timing of surgery. Materials and Methods: We retrospectively analyzed medical records and imaging for consecutive patients who underwent MSCT to investigate occult hip fractures between January 2014 and October 2016. We reviewed subsequent imaging and reattendances for patients with negative MSCT to exclude initially missed fractures. Results: Two hundred six patients underwent MSCT to investigate occult hip fracture during the study period. Hip fractures were identified in 59 patients, comprising 35 (59.3%) subcapital, 12 (20.0%) intertrochanteric, 8 (13.6%) transcervical, and 4 (6.8%) basicervical fractures. One missed hip fracture was identified: a patient with a negative MSCT was further investigated with MRI that demonstrated acute subcapital hip fracture. Multislice computerized tomography was obtained within 24 hours of initial radiograph in 145 (70.4%) patients. A total of 44.5% of occult hip fractures had surgery within the nationally recommended 36 hours of admission (hospital average for all hip fractures was 76.4% over the same period). Discussion and Conclusions: Multislice computerized tomography is a pragmatic approach to investigate the majority of occult hip fractures in a timely manner and minimize associated delay to surgery. However it cannot completely exclude the diagnosis, especially in abnormal anatomy. The lack of a true gold standard comparison (ie, MRI) means a true sensitivity and specificity cannot be calculated, although can be cautiously estimated by lack of subsequent reattendance or investigation. Further prospective randomized CT versus MRI trials are required.

Abstract
PURPOSE Patellar finger tapping produces a typical sound that can be detected by a stethoscope positioned on the pubic bone (patellar pubic percussion test (PPPT)). Characteristics of this sound are determined by continuity of bone between patella and pelvis. We hypothesized that a PPPT was able to detect overt hip fractures and occult hip fractures that may not be determined by a standard radiological examination. METHODS Two independent observers performed a PPPT in patients with a suspected hip or pelvic fracture, just before a conventional radiograph (X-ray) was performed. The PPPT test was scored as negative (similar to contralateral side) or positive (different). Patients with a positive PPPT but with a negative X-ray underwent an additional CT scan. RESULTS One hundred and ninety-one patients with suspected hip or pelvic fracture were included. A total of 161 patients (84%) were diagnosed with a fracture (hip, n = 142; pelvic, n = 19). An 85% sensitivity, a 70% specificity, a 0.94 positive predictive value, and a 0.47 negative predictive value of the PTTT were calculated. The inter-observer reliability (kappa) was 0.7. Eleven CT scans as indicated by a mismatch between PPPT (positive) and X-ray (no fracture) identified eight fractures (73%). A multivariate analysis demonstrated that a painful passive movement and the PPPT predicted a hip fracture. CONCLUSION The PPPT is a simple bedside diagnostic tool that is sensitive in detecting clinically straight forward hip fractures as well as occult hip fractures. The PPPT can support decision-making for additional radiological examinations in case of potential occult pelvis or hip fractures.

Deep vein thrombosis following the treatment of lower limb pathologic bone fractures - a comparative study. BMC Musculoskelet Disord 2018; 19:213. [PMID: 29996842 PMCID: PMC6042243 DOI: 10.1186/s12891-018-2141-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Accepted: 06/18/2018] [Indexed: 01/22/2023] Open
Abstract
Background Deep vein thrombosis is a well-known complication of fracture occurrence, lower limb surgery and periods of prolonged immobilisation. Its incidence can be increased even more in specific cases with metastatic bone disease and adjuvant treatment. There is a small amount of literature that addresses the incidence of DVT by comparing osteosynthesis and arthroplasty as surgical treatments. Current recommended anticoagulation protocols might be inadequate for specific groups of cancer patients undergoing osteosynthesis or arthroplasty. Methods The study was designed and performed in a retrospective manner and carried out on patients that presented at our Emergency Clinical County Hospital between 01.01.2008–31.12.2016. The patients’ evolution was followed for a standard of 2 months. All our deep vein thrombosis events were diagnosed via venous duplex imaging. The studied lot (n = 85) was paired with a control group (n = 170) with similar baseline characteristics. Results Our lot was comprised of 85 patients that underwent 85 surgeries, on both of our hospital’s Orthopaedic and Traumatology wards. When performing the student t-test and calculating OR (odds ratio) and RR (risk ratio) we encountered 11 cases of DVT in our studied group and 12 cases of DVT in our control group (p < 0.04). We found statistical significance when correlating DVT with type of implant (prosthesis), the presence of metastases over primary tumour and the choice of implant (prosthesis over intramedullary nail). There was no statistical significance found when correlating DVT events with the type of anticoagulation and the amount of blood transfusion units required. Conclusion Patients who undergo surgical treatment for lower limb pathological fracture due to malignancy are at increased risk of DVT or death due to PE under current general thromboprophylaxis regimens. The risk is higher for the immediate postoperative period (10 days). The risk is increased by metastasis, arthroplasty and adjuvant therapy (radiotherapy, chemotherapy), and we think that a more aggressive prophylactic protocol should be used.

Extra-articular distal tibia fractures-controversies regarding treatment options. A single-centre prospective comparative study. INTERNATIONAL ORTHOPAEDICS 2018; 42:915-919. [PMID: 29359259 DOI: 10.1007/s00264-018-3775-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Accepted: 01/08/2018] [Indexed: 12/24/2022]
Abstract
Distal tibia fractures are reported to have a high complication rate pre-operatively as well as post-operatively, which can include open fractures, soft tissue damage, infection, malalignment, pseudarthrosis and ankle arthrosis. The operative treatment for the extra-articular distal tibia fractures is a controversial topic in the orthopaedic literature. Some of these fractures are proximal enough to be treated with an intramedullary nail while others are too distal for that. The aim of our study was to compare the results we have had with intramedullary nail (IMN) and minimally invasive plate osteosynthesis (MIPO) in distal metaphyseal (extra-articular) tibia fractures. The study was designed prospectively between January 2013 and March 2016 and took place on the Orthopaedics and Traumatology ward of a Clinical Emergency County Hospital in western Romania. The follow-up visits were scheduled one month, three months and six months post-operatively. For evaluating the ankle function, we used the Olerud-Molander ankle score (OMAS) and union was evaluated at six months on ankle X-rays. At the six-month follow-up visit the average scores were 75.55 (20-100) for the IMN lot and 74.23 (20-90) for the MIPO lot, without finding any statistical difference between the two groups (p >0.1). At the six-month follow-up, X-ray union was objected in 48 (90.5%) of our patients, the IMN lot having worse results (85.18%) than the MIPO lot (96.15%). The results we encountered showed little to no statistical difference when it comes to the functional score we used (OMAS score), leading us to believe that you can achieve comparable results with both implants.

Abstract
PURPOSE We aimed to perform psychometric testing for the translated Oxford Hip Score (OHS) for use as a recommended tool to measure treatment outcomes. METHODS The original English questionnaire was translated and culturally validated using the instrument developer's guidelines and the ISPOR principles of good practice. One hundred patients completed the form together with the Harris Hip Score (HHS) and EQ-5D-5 L. Fifty patients repeated the form after two days. They were suffering from hip osteoarthritis, had had hip replacement or underwent osteosynthesis for a fracture of the trochanteric region. RESULTS The questionnaire had a high degree of reliability with a Cronbach α of 0.917 at the initial completion and 0.917 at the second testing, respectively. The two results were strongly positive and significantly correlated (Pearson's r = 0.947; p < 0.001). The OHS was strongly and significantly correlated with the HHS (Pearson's r = 0.880 initial and r = 0.840 s; p < 0.001) and strongly, positive and significantly correlated with the EQ-5D-5 L VAS (Pearson's r = 0.614 initial and r = 0.704 s; p < 0.001). CONCLUSIONS Our study showed that the translation of the OHS is a reliable, reproducible and valid measure of function in patients who undergo treatment for hip pathology.
