Abstract
OBJECTIVE Intertrochanteric fracture of the femur is a common fracture in older people. Due to the poor systemic condition and prognosis of elderly patients, it is prone to more complications. We introduce the bone-setting concept in the design of the robots, which are used for intertrochanteric fracture of the femur reduction. The purpose of this study is to compare the effect of bone-setting robots and conventional reduction in the treatment of intertrochanteric fracture of the femur (IFF). METHODS From June 2021 to January 2023, 60 patients with IFF who were treated surgically were assigned to bone-setting robots group and conventional reduction methods group in this retrospective study. The reduction time, operation time, total time, intraoperative blood loss, incision length, fluoroscopy time, and the follow-up time were reviewed. The visual analogue scale (VAS) and Harris scores were used for functional assessment. For continuous variables, independent t-tests were applied; for categorical data, the chi-square test was applied. The significance level as p < 0.05. RESULTS Among the 60 patients with IFF, 31 were assigned to the bone-setting robots group, and 29 were assigned to the conventional reduction methods group. Both groups with a similar baseline in the number, gender, age, and classification (p > 0.05). The reduction time, operation time, total time, intraoperative blood loss, and fluoroscopy time were less than those in the bone-setting robots reduction group compared to the conventional reduction group. In the bone-setting robots reduction group, the preoperative VAS score was 6.2 ± 1.3, the Harris score was 35.3 ± 3.1, 1 week after surgery VAS score was 3.3 ± 1.2, the Harris score was 57.3 ± 3.7, and at the last follow-up VAS score was 2.4 ± 0.8, and the Harris score was 88.7 ± 3.4. While in the conventional reduction group, the preoperative VAS score was 6.3 ± 1.3, the Harris score was 35.9 ± 2.9, 1 week after surgery VAS score was 4.8 ± 1.4, the Harris score was 46.8 ± 2.8, and at the last follow-up VAS score was 2.6 ± 0.8, and the Harris score was 87.3 ± 3.3. There were no significant differences between the two groups at the preoperative and 6-month postoperative follow-ups in VAS score and Harris score (p > 0.05, p > 0.05, respectively). But the difference was statistically significant at the one-week postoperative follow-up in VAS and Harris scores (p < 0.001). CONCLUSION The bone-setting robots can better protect the "fracture environment" and have the advantages of being precise, minimally invasive, simple, short time, low radiation, and rapid fracture recovery. The clinical effect of closed repair of IFF is ideal.

Intertrochanteric Femoral Fractures: A Comparative Analysis of Clinical and Radiographic Outcomes Between Talon Intramedullary Nail and Intertan Nail. Cureus 2023; 15:e50877. [PMID: 38259364 PMCID: PMC10801105 DOI: 10.7759/cureus.50877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/20/2023] [Indexed: 01/24/2024] Open
Abstract
Introduction Hip fractures in the elderly constitute a significant health concern, and their incidence is on the rise. It has been reported that intertrochanteric femoral fractures comprise a large portion of hip fractures, and they are especially prevalent among women. Over 75% of these types of fractures in the elderly occur as a result of simple falls. Surgical intervention must be performed for these fractures to expedite the healing process in patients. The application of a proximal femoral nail (PFN) is conducted using a minimally invasive technique after the fracture has been reduced using closed techniques. This technique maintains the fracture hematoma while minimizing the occurrence of consequences such as surgical trauma, hemorrhaging, infection, and issues with the wound site. This study aimed to assess the radiologic and functional outcomes among the groups following surgical procedures utilizing two distinct PFNs. Methods Between November 2021 and June 2023, a total of 96 individuals (38 males and 58 females) who underwent surgery for ITF using PFN were included in the study. Our surgical team utilized the Talon™ DistalFix™ PFN system (Orthopedic Designs North America Inc., FL, USA) and the Trigen InterTAN® nail (Smith & Nephew). Results The surgery time (number of scopes) for the Talon PFN was recorded as 25 (25-30), while it was 30 (30-35) in the InterTAN group (p<0.001). No nail protrusion was observed in the InterTAN group, whereas nail protrusion was observed in 12 patients (31.6%) in the Talon PFN group (p<0.001). Nail jamming was observed in two (5.3%) patients in the Talon PFN group, while none was observed in the InterTAN group (p<0.07). Conclusion In ITF fractures, the InterTAN nail is a more reliable implant. The shorter surgery time, reduced radiation exposure, and more minimally invasive nature of the Talon PFN might be preferred for geriatric patient populations with comorbidities where prolonged anesthesia could elevate mortality risks or for fractures of two or three pieces (Evans-Jansen Type 1 and Type 2). However, for more unstable fractures (Evans-Jensen Type 3) and in the active elderly patient group, we recommend the use of the InterTAN nail.

[PMID: 37643944 DOI: 10.1016/j.injury.2023.111009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/30/2023] [Accepted: 08/21/2023] [Indexed: 08/31/2023]
Abstract
INTRODUCTION Dynamization of proximal femoral nailing by removal of distal interlocking is one of the recommended treatment options for nonunions of femur fractures. However, in certain inter-/subtrochanteric fractures, gliding of the nail along the femoral shaft is blocked by lateral femoral cortical support of the lag screw. For these cases, Biber et al. proposed lateral cortical notching (LCN), in which the supporting lateral bone is removed. This study investigates the biomechanical effect of LCN on gliding of proximal femoral nailing and stress distribution at the bone/implant interface. MATERIALS AND METHODS In this finite element analysis a three-dimensional model of an unstable intertrochanteric fracture with proximal femoral nailing without distal interlocking was simulated using the FebioStudio software suite. To simulate LCN, the lag screw hole was lengthened to 15.34 mm at the lateral cortex. Displacement of the nail along the femoral shaft axis and von Mises stress distribution were compared between LCN model and standard implantation model. RESULTS Displacement of the nail along the femoral shaft axis was higher in the LCN model than in the standard implantation model (0.48 mm vs. 0.07 mm). Highest von Mises stresses of 176-178 MPa at the implant and of 52-81 MPa at the proximal femur were detected. Maximum von Mises stresses of the implant were comparable at all sides, except for a reduced von Mises stress at the lateral inferior side in the LCN model (80 vs. 102 MPa). At the inferior lateral screw hole and the anterior/posterior lateral screw hole maximum von Mises stress was reduced in the LCN model (2 vs. 49 MPa and 52 vs. 81 MPa), whereas the maximum von Mises stress at the inferior medial screw hole was higher in the LCN model than in the standard implantation model (53 vs. 27 MPa). CONCLUSIONS Lateral cortical notching facilitates gliding of a distally dynamized proximal femoral nail along the femoral shaft axis in intertrochanteric fractures. Additionally, the lack of lateral cortical bone support at the lag screw reduces von Mises stress at the bone/implant interface and thus could lower the risk for implant breakage and peri‑implant fractures.

[PMID: 36635155 PMCID: PMC10071317 DOI: 10.1016/j.cjtee.2022.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 11/23/2022] [Accepted: 12/05/2022] [Indexed: 12/23/2022] Open
Abstract
PURPOSE Long proximal femoral nail anti-rotation (PFNA-II) is a preferred implant in recent years for fixation of pertrochanteric fractures, especially in osteoporotic patients. The purpose of this study is to prospectively investigate the effect of distal locking in long PFNA-II fixation of stable intertrochanteric fractures. METHODS A total of 58 patients with isolated stable intertrochanteric fractures and treated in our hospital during the study period of 2017-2019 by distal locked or unlocked long PFNA-II fixation were included in this study. Patients who had multiple injuries or open fractures were excluded. There were 40 female and 18 male patients, with 33 affecting the left side and 25 the right side. Of them, 31 belonged to the distal locked group (group A) and 27 to the unlocked group (group B). Surgical procedures and implants used in both groups were similar except for the distal locking of the nails. General data (age, gender, fracture side, etc.) showed no significant difference between two groups (all p > 0.05). The intraoperative parameters like operative time, radiation exposure and follow-up parameters like functional and radiological outcomes were recorded and compared. Statistical tests like the independent samples t-test Fischer's exact and Chi-square test were used to analyze association. RESULTS The distribution of the fractures according to AO/OTA classification and 31A1.2 type of intertrochanteric fractures were most common in our study. All the included fractures united and the average functional outcome in both groups were good and comparable at the end of one year. The operative time (mL, 107.1 ± 12.6 vs. 77.0 ± 12.0, p < 0.001) and radiation exposure (s, 78.6 ± 11.0 vs. 40.3 ± 9.3, p < 0.001) were significantly less among the patients in group B. Fracture consolidation, three months after the operative procedures, was seen in a significantly greater proportion of patients in group B (92.6% vs. 67.7%, p = 0.025). Hardware irritation because of distal locking bolt was exclusively seen in group A, however this was not statistically significant (p = 0.241). CONCLUSION We conclude that, in fixation of stable intertrochanteric fractures by long PFNA-II nail, distal locking not only increases the operative time and radiation exposure but also delays the fracture consolidation and increases the chances of hardware irritation, and hence is not required.

Abstract
PURPOSE Non-prosthetic peri-implant fractures are challenging injuries. Multiple factors must be carefully evaluated for an adequate therapeutic strategy, such as the state of bone healing, the type of implant, the time and performed personnel of previous surgery, and the stability of fixation. The aim of this study is to propose a rationale for the treatment. METHODS The peri-implant femoral fractures (PIFFs) system, a therapeutic algorithm was developed for the management of all patients presenting a subtype A PIFF, based on the type of the original implant (extra- vs. intra-medullary), implant length and fracture location. The adequacy and reliability of the proposed algorithm and the fracture healing process were assessed at the last clinical follow-up using the Parker mobility score and radiological assessment, respectively. In addition, all complications were noticed. Continuous variables were expressed as mean and standard deviations, or median and range according to their distribution. Categorical variables were expressed as frequency and percentages. RESULTS This is a retrospective case series of 33 PIFFs, and the mean post-operative Parker mobility score was (5.60 ± 2.54) points. Five patients (15.1%) achieved complete mobility without aids (9 points) and 1 (3.0%) patient was not able to walk. Two other patients (6.1%) were non-ambulatory prior to PPIF. The mean follow-up was (21.51 ± 9.12) months (range 6-48 months). There were 7 (21.2%) complications equally distributed between patients managed either with nailing or plating. There were no cases of nonunion or mechanical failure of the original implant. CONCLUSION The proposed treatment algorithm shows adequate, reliable and straightforward to assist the orthopaedic trauma surgeon on the difficult decision-making process regarding the management of PIFF occurring in previously healed fractures. In addition, it may become a useful tool to optimize the use of the classification, thus potentially improving the outcomes and minimizing complications.

Abstract
PURPOSE The Gamma3 nail (Stryker®) is an intramedullary device consisting of a proximal lag screw and distal interlocking screw. It is still unknown whether the screw locking mode could influence clinical outcomes. The aim of this study is to compare static and dynamic screw locking regarding their influence on surgical revisions and lag screw displacement. METHODS A retrospective single-centre study was performed on patients ≥ 60 years admitted for a trochanteric fracture between September 2016 and January 2020. Surgical revisions and lag screw displacement were evaluated at 6 weeks and 1-year follow-up, respectively. RESULTS A total of 142 patients were included for analysis. Surgical revisions were needed in 13 cases (9.2%). Indications included implant breakage (n = 3), lag screw cut-out (n = 3), lateral hip pain (n = 6) and non-union (n = 1). The number of surgical revisions was not different between static and dynamic locking (OR 2.55; 95%CI 0.73-8.56; p 0.142). The median lag screw displacement was 2.5 mm, which was similar for static and dynamic locking (2.3 mm versus 2.7 mm; p 0.785). CONCLUSION The screw locking mode of the Gamma3 nail is not associated with a higher risk of surgical revisions. However, the design of the Gamma3 nail may not be suitable for static locking.

Abstract
INTRODUCTION Cephalomedullary nailing (CMN) is the standard treatment for internal fixation of trochanteric fractures. Complications related to CMN include intraoperative fracture (IF), which is difficult to detect using only plain radiographs. However, analyses of IFs using plain radiographs and computed tomography (CT) with a large sample size of clinical cases are lacking. Therefore, this study aimed to report the incidence of IFs diagnosed by CT, the risk factors for IFs, and a comparison of clinical outcomes between patients with and without IFs. METHODS This multicenter retrospective cohort study included 638 patients who underwent CMN fixation for trochanteric fractures. We evaluated IF using pre-and postoperative plain radiographs and CT. The primary outcome was reoperation and the secondary outcome was the proportion of patients who regained independent mobility at 3 months postoperatively. Furthermore, we conducted multivariable logistic regression analyses to examine the association between risk factors and IFs. RESULTS Seventy-five (11.8%) patients had IFs, including 53 patients with occult IFs (8.3%). The most common location of IF was at the interference with the lag screw entry (45.3%). The nail insertion procedure (17.3%) was the most common reason for IF. In the assessment of clinical outcomes, patients with IFs had no reoperations and independent mobility at postoperative 3 months was lower (69.6% vs. 79.1%). Regarding regaining independent walking in the IF group, IF distal to lag screw entry and obvious IF diagnosed with plain radiographs were poor factors. The multivariable analysis showed that only inadequate reduction on the anteroposterior view based on the plain radiograph was significantly associated with the incidence of IFs (odds ratio 3.91; 95% CI, 1.28-11.94; p = 0.017). CONCLUSIONS This multicenter study indicated that the incidence of IFs detected by CT in CMN treatment for trochanteric fractures was 11.8%. An inadequate reduction in the anteroposterior view based on plain radiographs was the only independent risk factor of IFs. In the assessment of clinical outcomes, patients with IF had no incidences of reoperation. However, patients with IFs tended not to regain independent mobility compared with those without IFs.

Abstract
Interlocking of intramedullary nails is a challenging procedure in orthopedic trauma surgery. Numerous methods have been described to facilitate this process. But they are exposed patient and surgical team to X-rays or involves trial and error. An accurate and non-invasive method has been provided to easily interlocking intramedullary nails. By transferring a safe visible light inside the nail, a drilling position appears which use to drilling bone toward the nail hole. The wavelength of this light was obtained from ex-vivo spectroscopy on biological tissues which has optimal transmission, reflectance, and absorption properties. Moreover, animal and human experiments were performed to evaluate performance of the proposed system. Ex-vivo performance experiments were performed successfully on two groups of cow and sheep samples. Output parameters were procedure time and drilling quality which there were significant differences between the two groups in procedure time (P < 0.05). But no significant differences were observed in drilling quality (P > 0.05). Moreover, an In-vivo performance experiment was performed successfully on a middle-aged man. To compare the provided method, targeting-arm, and free-hand techniques, two human experiments were performed on a middle-aged and a young man. The results indicate the advantage of the proposed technique in the procedure time (P < 0.05), while the drilling quality is equal to the free-hand technique (P = 0.05). Intramedullary nail holes laser indicator is a safe and accurate method that reduced surgical time and simplifies the process. This new technology makes it easier to interlocking the intramedullary nail which can have good clinical applications.

Abstract
Background The treatment for intertrochanteric femoral fractures (IFF) among the elderly has been a controversial topic. Hemiarthroplasty (HA) and proximal femoral nail antirotation (PFNA) have their own advantages in the management of IFF. Hence, this study aims to compare and analyze differences in the effectiveness of both procedures on IFF among the elderly. Methods Overall, 99 patients (81.09 ± 8.29 years; 68 women) underwent HA or PFNA from January 2016 to May 2020. IFF were classified according to the Arbeitsgemeins für Osteosynthesefragen (AO) classification. The difference in underlying diseases, the American Society of Anesthesiologists (ASA) grade, Singh index, Harris scores, surgical time, intraoperative bleeding, postoperative blood test results, postoperative number of days to partially bearing weight, and survival outcomes were analyzed. Postoperative follow-ups were performed every 3 months. Results There was no significant difference in the AO classification, underlying diseases, ASA grade, Singh index, surgical time, and survival outcomes of the HA (45 patients) group and PFNA group (54 patients). The HA group was associated with earlier partial weight-bearing (HA: 4 [2 ~ 4.5] days, PFNA: 10 [8~14] days). It also had a higher total Harris score than the PFNA group at the 6-month follow-up visit (HA: 86.8 [81.90 ~ 90.23], PFNA: 83.48 [75.13 ~ 88.23]). Harris scores decreased more in patients aged ≥90 years in the PFNA group than in the HA group. The postoperative stress recovery rate in the HA group was faster based on postoperative blood test results. Conclusions PFNA and HA have good therapeutic effects in the treatment of IFF. The advantages of HA were reflected in short-term weight bearing, faster recovery from stress, and better joint function in the long term. This advantage is more obvious in the patient population aged over 90 years. Therefore, we suggest that surgeons should consider the benefit of HA in the treatment of IFF among the elderly.

Management of pertrochanteric fractures in patients over 90 years: In-hospital mortality rate, complications and associated risk factors. BMC Musculoskelet Disord 2021; 22:799. [PMID: 34530792 PMCID: PMC8447507 DOI: 10.1186/s12891-021-04683-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Accepted: 08/31/2021] [Indexed: 02/05/2023] Open
Abstract
PURPOSE This study aims primarily to investigate the outcome following surgical management of pertrochanteric fractures of patients over 90 years compared to the outcome of a control group below 90 years under special consideration of the timing of surgery. The second aim was to analyze potential risk factors for early deaths in very old patients. This study allows us to draw conclusions to minimize complications linked to this particular age segment. METHODS The study group consisted of very old patients aged 90 years and older. Geriatric patients aged between 60 and 89 years of age were part of the control group. Type A1 pertrochanteric fractures were typically treated by dynamic hip crews, type A2 and A3 fractures by femoral nails. Full weight bearing physiotherapy was initiated on the day after surgery to improve mobility and muscle strength. RESULTS A total of 71 patients belonged to the study group (mean age: 92.5 years ±2.3 years), whereas 223 patients formed the control group (mean age: 79.9 ± 7.4 years). The mortality rate and the number of detected and documented complications were significantly higher in the study group (p = 0.001; p = 0.009, respectively). Despite the significantly higher complication rate in the > 90-year-old patients, there was no significant difference in the mean length of in-hospital-stay between the both groups (> 90 yrs.: 12.1d; < 90 yrs.: 13.1 d) and the timing of surgery. CONCLUSION The number of co-morbidities, number of daily-administered medications and the time between admission and surgery have no impact on the outcome. We noticed a longer period between admission and surgery in very old patients who survived. Patients with pertrochanteric fractures should be screened for multimorbidity and cognitive disorders in a standardized manner.

Abstract
There is no study that has compared the radiation exposure during short (Short PFN) and long proximal femoral nailing (Long PFN) for 31A2 intertrochanteric hip fractures. The objective of the present study was to compare the radiation exposure time in short and long proximal femoral nail during the treatment of 31A2 intertrochanteric hip fractures. This prospective cohort study was carried out in a University teaching hospital. Sixty one consecutive patients with 31A2 intertrochanteric femur fracture treated with pro- ximal femoral nail were included in the study. The distal locking in the short PFN was performed using the locking zig and distal locking in the long PFN was performed using the free hand perfect circle technique. The same mobile image intensifier (Multimobil 5E, Siemens, Erlangen, Germany) was used in the entire study. The outcome measure was the fluoroscopy exposure time (seconds) which was measured directly from the image intensifier. Thirty patients underwent fixation with short PFN and 31 patients underwent fixation using long PFN. The mean fluoroscopy exposure time in short PFN cohort was 189.5 seconds ± 26 (range : 150-250 seconds) and the mean fluoroscopy exposure time in long PFN cohort was 283.4 seconds ± 43.8 (range : 200-400 seconds). The mean fluoroscopy exposure time was 93.9 seconds shorter in the short PFN cohort and this difference was statistically significant (p < 0.0001 ; 95% CI : 75.4 to 112.3). The radiation exposure to the operating team is significantly less during treatment with short PFN in 31A2 intertrochanteric fractures.

Additional use of anti-rotation U-blade (RC) decreases lag screw sliding and limb length inequality in the treatment of intertrochanteric fractures. Sci Rep 2021; 11:17417. [PMID: 34465817 PMCID: PMC8408211 DOI: 10.1038/s41598-021-96988-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 08/06/2021] [Indexed: 12/05/2022] Open
Abstract
The purpose of this study is to compare the cut-out rate and sliding distance associated with limb length inequality between operations using a standard non-sliding lag screw versus those using a non-sliding lag screw with U-blade (RC) in the Gamma3 nail. This is a retrospective review of two case series involving different lag screws for the Gamma3 nail. Propensity score matching analysis was used to adjust the confounding factors. A comparative analysis of 304 patients who treated with Gamma3 nail with either a standard non-sliding lag screw or a U-Blade (RC) lag screw was performed. Between 2014 and 2018, 152 patients were treated with U-blade (RC) lag screws, and these patients were matched with those treated with standard lag screws. There was no significant difference in cut-out rate between groups. However, additional use of anti-rotation U-blade (RC) could significantly decrease lag screw sliding, with the group treated with U-Blade (RC) lag screws exhibiting shorter sliding, especially in AO/OTA31 A2 and A3 fractures. Also, in A2 and A3 fractures, the mean lag screw sliding distance was greater than that seen in A1 fractures in both groups. These findings can help trauma surgeons choose the proper implant to reduce leg length inequality.

Abstract
OBJECTIVES Despite continual improvement in the methods and devices used for treatment of proximal femoral fractures, unacceptably high failure rates remain. Novel screw-blade implant systems, combining a lag screw with a blade - the latter adding rotational stability to the femoral head - offer improvement of osseous purchase, especially in osteoporotic bone. The aim of this study was to compare biomechanically the head element (HE) anchorage of two screw-blade implant systems differing in blade orientation in the femoral head - vertical versus horizontal. METHODS Twenty paired human cadaveric femoral heads were assigned to four groups (n = 10), implanted with either Rotationally Stable Screw-Anchor HE (RoSA-HE, vertical blade orientation) or Gamma3 Rotation Control Lag Screw (Gamma-RC, horizontal blade orientation) in center or off-center position, and biomechanically tested until failure under progressively increasing cyclic loading at 2 Hz. RESULTS Cycles to failure and failure load were significantly higher for Gamma-RC versus RoSA-HE in center position and not significantly different between them in off-center position, p = 0.03 and p = 0.22, respectively. In center position, the progression of both rotation around implant axis and varus deformation over time demonstrated superiority of the implant with horizontal versus vertical blade orientation. Compared with center positioning, off-center implant placement led to a significant decrease in stiffness, cycles to failure and failure load for Gamma-RC, but not for RoSA-HE, p < 0.01 and p = 0.99, respectively. CONCLUSION Horizontal blade orientation of screw-blade implant systems demonstrates better anchorage in the femoral head versus vertical blade orientation in center position. As the stability of the implant system with horizontal blade orientation drops sharply in off-center position, central insertion is its placement of choice.

Abstract
Objective This study evaluated the rates and patterns of intramedullary nail (IMN) breakage and mechanical displacement for proximal femur fractures and the factors associated with their occurrence. Patients and Methods Patients with subtrochanteric, intertrochanteric, or basicervical femoral neck fractures treated with IMN from 2016 to 2019 were identified from commercial and Medicare supplemental claims databases and were followed for up to two years. Kaplan–Meier analysis estimated the cumulative incidence of and patterns of breakage/mechanical displacement. Multivariable Cox regression models evaluated the factors associated with breakage/mechanical displacement. Results A total of 11,128 patients had IMN fixation for subtrochanteric, intertrochanteric, or basicervical femoral neck fractures: (mean SD) age 75.6 (16.4) years, 66.2% female, 74.3% Medicare supplemental vs 26.7% commercial insurance. Comorbidities included hypertension (62.9%), osteoporosis (27.3%), cardiac arrhythmia (23.1%), diabetes (30.7%), and chronic pulmonary disease (16.3%). Most fractures were closed (97.2%), intertrochanteric or basicervical femoral neck (80.1%), and not pathological (91.0%). The cumulative incidence of nail breakage over two years was 0.66% overall, 1.44% for combination fractures, 1.16% for subtrochanteric fractures, and 0.49% for intertrochanteric or basicervical fractures. The cumulative incidence of mechanical displacement was 0.37% overall, 0.43% for subtrochanteric fractures, 0.42% for combination fractures, and 0.36% for intertrochanteric or basicervical femoral neck fractures. Half of the breakages occurred within five months after surgery and half of the mechanical displacements occurred within 75 days. Age 50–64 (vs 75+) and subtrochanteric or pathological fracture were more commonly associated with nail breakage. Complicated hypertension was more commonly associated with mechanical displacement. Conclusion The incidence of IMN breakage and mechanical displacement in US commercial and Medicare supplemental patients with proximal femur fractures from 2016 to 2019 was low (0.66% and 0.37%, respectively up to two years). Age 50–64 (vs 75+) and subtrochanteric or pathological fracture were more commonly associated with breakage. Complicated hypertension was associated with mechanical displacement.

Abstract
BACKGROUND Normally taking the surgery is the standard treatment, between sliding hip screw (SHS) and utilizing proximal femoral nail antirotation (PFNA) for intramedullary fixation, it is still not certain which one work better for this type of fracture. Our purpose for this study was to determine the optimum choice of implant for a patient with an unstable intertrochanteric fracture. METHODS In our hospital, a reflective analysis was conducted of all unstable intertrochanteric fractures treated with either a SHS or PFNA fixation between February 2015 and February 2018. The rules of choosing patients were the following: older age of more than 60, unstable intertrochanteric fractures, and willingness to take clinical and radiographic follow-up researches for over 12 months. In this case, patients bearing former hip surgery at any side were removed from the candidates. Demographic characteristics collected effective information including gender, date of operation, and other relevant information. Postoperative outcome measures included operation time, total blood loss amount, validated mobility score, surgery-related syndrome, and tip-apex length. The patients were re-examined at three time periods: 3 weeks, 3 months, and 1 year. The result of P < .05 was considered to be statistically significant. RESULTS We were able to directly compare the outcomes of PFNA vs SHS techniques and might reveal a better technique in treatment of an unstable intertrochanteric fracture. TRIAL REGISTRATION This study protocol has been registered in Research Registry (researchregistry6057).

Abstract
Pertrochanteric hip fractures are among the most common and the use of short cephalomedullary nails as the treatment of choice is increasing. A systematic review regarding distal locking options for short cephalomedullary nails was undertaken using Medline/PubMed®, Embase® and Cochrane Library® in order to evaluate current indications, associated complications and to provide treatment recommendations. The results seem to support the use of distal static locking for unstable fractures, dynamic locking for length stable/rotational unstable fractures and no locking for stable fractures. Complications associated with distal locking include iatrogenic fractures, thigh pain, delayed union and nonunion, implant failure, screw loosening and breaking, drill bit breaking, soft tissue irritation, femoral artery branch injury, intramuscular haematoma and compartment syndrome. It is also associated with longer operative time and radiation exposure. In unlocked constructs, dorsomedial comminution and nail/medullary canal mismatch contribute to peri-implant fractures. Anterior cortical impingement is associated with cut-out and nonunion. Most studies comparing distally locked and unlocked nails report a short follow-up. Distal locking mode should be based on the fracture’s stability.

Abstract
BACKGROUND Intramedullary nails have become the main treatment for intertrochanteric fractures. However, a distal locking procedure during nailing gradually raised controversy. In this study, a systematic review and meta-analysis of clinical trials was performed to summarize existing evidence, aiming to determine the safety and efficacy of distal locking or unlocking in the nailing of stable intertrochanteric fractures. METHODS Appropriate articles were identified using the most common public databases, such as PubMed, Embase, the Cochrane Library, and Google Scholar from the inception of each database to April 2019, without restriction of language, publication date, and considering ongoing trials. Eligible studies were represented by randomized controlled trials or retrospective cohort studies, comparing distal locking and unlocking for the treatment of acute stable intertrochanteric fractures in adult patients. Information regarding methodological quality, patient demographics, and clinical outcomes were extracted independently by two reviewers. Subsequently, patients were divided into a locking and unlocking group. RESULTS This study included 9 articles, comprising a total of 1978 patients with a similar baseline. The results showed that the unlocking group had a shorter operation time, less intraoperative bleeding, lower transfusion rate, and less thigh pain after the treatment of femoral intertrochanteric fracture when compared with the distal locking group. No significant differences were observed in safety-related outcomes, including mortality, infection rate, cutting out, loss of reduction, backing out of lag screws, cephalic screw breakage, nail breakage, and peri-implant fractures between the two groups. In addition, efficacy-related outcomes including nonunion, delayed healing rates, and the Harris functional score were not significantly different between the two groups. CONCLUSIONS Our pooled analysis demonstrated that distal unlocking of stable intertrochanteric fractures can shorten the operation time, reduce intraoperative bleeding, and reduce the blood transfusion rate. The use of locked or unlocked intramedullary nailing does not affect long-term outcomes regarding complications and function.

Abstract
Objective: To compare the outcome of distal locked and unlocked intramedullary nailing in patients with intertrochanteric fractures through systematic review and meta-analysis of randomized and non-randomized clinical trials. Methods: Randomized or non-randomized controlled studies comparing the effects of unlocked and locked nails for treatment of intertrochanteric fractures were searched using the search strategy of Cochrane collaboration up to April 2019. Four eligible studies involving 691 patients were included. Their methodological quality was assessed, and data were extracted independently for meta-analysis. Results: The results showed that the unlocked group has significantly less operative time (MD: -8.08; 95%CI -11.36 to -4.79; P< 0.00001), fluoroscopy time (MD: -7.09, 95%CI -7.09 to -4.79; p<0.00001), length of incision (MD: -2.50, 95%CI 2.85 to -2.14; p< 0.00001) than the locked group. The complication rate was significantly higher in the locking group (OR: 0.55, 95%CI 0.26 to 1.15; p=0.03). No significant differences were found in the Harris hip score between the two groups (MD: 0.68, 95% CI -0.83 to 2.19, p<0.08). Conclusion: The present meta-analysis suggests that intramedullary nailing without distal locking is reliable and acceptable option for treating intertrochanteric fracture. The advantages are reduced operative time, decreased fluoroscopy time, smaller size of incision and decreased complication rate. However, owing to the low-quality evidence currently available, additional high quality Randomized controlled trials are needed to confirm these findings.

Abstract
Introduction: Postoperative pain management in the total knee replacement (TKR) represent a fundamental step for a positive outcome, allowing rapid mobilization, already on the first day. Further, continuous peripheral nerve block techniques have been reported to allow effective and safe control of acute postoperative pain, ensuring the implementation and completion of an accurate and intensive joint rehabilitation program. Aim: The aim of this study was to assess early mobility and compliance of patients that underwent TKR surgery using the femoral block. Methods: For the study, all patients that underwent TKR from 2015 to 2018 with ASA score between II-III was evaluated. Patients underwent vital parameters monitoring and were treated initially with midazolam (0.05mg / kg) e.v. combined sciatic block + femoral perineural catheter positioning using a peripheral nerve stimulation-assisted technique. Results: Intraoperatively, satisfactory analgesia was guaranteed in all patients, associated with a complete muscle relaxation of the affected limb. High patient compliance, associated with good control of acute postoperative pain was obtained in the first 24 hours after surgery (VAS 0- 1). The ROM outcomes were good in all rehabilitation stages, managing to reach 90 degrees bending on the seventh day with an average KSS score of 88-90. Patient satisfaction and impact on quality of life were assessed with the SF-36 showing average scores of 78. Conclusion: Continuous femoral nerve blocking ensures good postoperative analgesia in TKR allowing an early joint mobilization, a rapid functional recovery of the knee and increasing patient compliance during the post-operative rehabilitation program.

Relationship between the AB0 Blood System and Proximal Femoral Fracture Patterns in the Turkish Population. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1834525. [PMID: 32280678 PMCID: PMC7114767 DOI: 10.1155/2020/1834525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 01/18/2020] [Accepted: 02/17/2020] [Indexed: 11/18/2022]
Abstract
Objective. AB0 blood groups have shown to be associated with increased risk of several orthopedic disorders such as Achilles tendon rupture and hip osteoarthritis. The objective of this study was to investigate relationships between the AB0 blood system and hip fracture patterns, duration of hospitalization, and amount of blood transfusion. Methods. Data of 308 patients treated due to hip fractures in our hospital between 2017 and 2019 were evaluated. Epicrisis reports and X-rays of the patients included in this study were retrospectively screened, and hip fractures were classified as intracapsular and extracapsular fractures. Patients were divided into A, B, 0, and AB groups according to blood groups. Results. The mean age of the patients was 75.54±13.5 years. Of all patients, 103 had an intracapsular fracture and 205 had an extracapsular fracture. No statistically significant correlation was found between blood groups and fracture patterns. No statistically significant difference was found between the amounts of transfusion according to the blood groups, and no significant difference between the durations of hospitalizations according to the blood groups. Conclusion. In our study population, we could not find a significant relationship between the AB0 blood system and fracture patterns. We think that these potential relationships could be explained with further comprehensive studies with larger populations.

Abstract
BACKGROUND To date, there are just several studies comparing distal locked nails with distal unlocked nails in treating intertrochanteric fractures. We report the first meta-analysis about this issue. METHODS Systematic search was conducted for studies in PubMed, Embase and Cochrane Library. Meta-analyses were performed regarding intra operative outcomes, complications and functional outcomes. RESULTS Pooled results showed insignificant difference between distal locking group and distal unlocking group in hip pain (relative risk (RR) 1.14, 95% confidence interval (CI) 0.59-2.19), distal tip fracture (RR 1.08, 95% CI 0.37-3.11), lag screw cut-out (RR 1.60, 95% CI 0.54-4.78), delayed or nonunion (RR 1.32, 95% CI 0.25-7.06), deep vein thrombosis (RR 1.06, 95% CI 0.23-4.84), wound infection (RR 0.58, 95% CI 0.28-1.22), Harris hip score (standard mean deviation (SMD) 0.03, 95% CI -0.15 to 0.21) and walking ability. However, significant difference was detected in operation time (SMD 0.77, 95% CI 0.36-1.17), fluoroscopy exposure time (SMD 1.02, 95% CI 0.52-1.52), blood loss (SMD 0.80, 95% CI 0.62-0.99) and total incision length (SMD 1.16, 95% CI 0.86-1.47). Result of trial sequential analysis indicated conclusive evidence. CONCLUSION Current evidence indicates that the distal locked intramedullary nails should not be recommended as routine choice for stable intertrochanteric fractures.

Breakage in Two Points of a Short and Undersized "Affixus" Cephalomedullary Nail in a Very Active Elderly Female: A Case Report and Review of the Literature. Case Rep Orthop 2018; 2018:9580190. [PMID: 30302297 PMCID: PMC6158977 DOI: 10.1155/2018/9580190] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 08/27/2018] [Indexed: 11/24/2022] Open
Abstract
Introduction Trochanteric fractures of the femur are common in elderly individuals with osteoporosis. The use of cephalomedullary nails is increasing, and they are now the most commonly used fixation devices, especially for the treatment of unstable trochanteric fractures. The nail breakage is not the most common complication of intramedullary nailing. Many scientific papers report nail breakage in a specific location: through the lag screw hole, the nail shaft, or the distal locking hole. Materials and Methods We present a case of an 84-year-old patient treated with modular revision hip arthroplasty due to the breakage in two points of a cephalomedullary nail implanted 3 years earlier for a subtrochanteric fracture. Results After modular revision hip arthroplasty, the functional results and quality of life have been excellent. Conclusions As far as we could determine, this appears to be the first case of a breakage of a cephalomedullary nail in two points after nonunion in a very active elderly female.
