Abstract
Objectives This study investigates outcomes and complications of the pin and plate fixation technique, which was suggested for distal humerus fractures. It also reports the results of its application in nonunions for the first time. Methods Forty-nine fracture and 17 nonunion cases who underwent surgery using the technique and were followed for at least 18 months were assessed through the range of motion (ROM), Quick Disabilities of the Arm, Shoulder, and Hand Score (Quick-DASH), Mayo Elbow Performance Score (MEPS), four-category verbal rating scale (VRS-4), and complications. Results At the last follow-up, the mean scores of flexion, extension deficit, supination, and pronation ranges in fracture cases were 116.7, 22.9, 90.0, and 90.0 degrees, respectively. These values in nonunion cases were 112.2, 26.4, 86.7, and 85.5 degrees, respectively. The average ROM in fracture cases was 93.8, while it was 85.8 degrees in nonunion cases. The mean Quick-DASH in fracture and nonunion patients were 25.2 and 31.1, respectively. According to the MEPS, 77.5% of fracture and 64.7% of nonunion patients had excellent and good results. In fracture cases, the mean scores of VRS-4 at rest, light activity, and hard activity were 1.3, 1.8, and 2.3, respectively. These values in nonunion cases were 1.8, 2.2, and 2.5, respectively. The most common complications were device prominence and ulnar neuropathy. Conclusion An acceptable union rate and proper elbow function can be expected by using this technique. Owing to the promising results of this study, further high-quality studies are recommended. Hereby this technique is called Persian Fixation.

THE ARCHIVES OF BONE AND JOINT SURGERY 2023; 11:658-661. [PMID: 37873524 PMCID: PMC10590491 DOI: 10.22038/abjs.2023.70015.3286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 04/18/2023] [Indexed: 10/25/2023]
Abstract
An obese 57-year-old woman with known hypertension and diabetes mellitus sustained multiple injuries during an accident, which caused anterior-posterior fracture-dislocation of the pelvic ring. Due to the drawbacks of conventional stabilizing methods for anterior-posterior fracture-dislocations of the hip in this setting, such as the inability to visualize anatomical landmarks fluoroscopically for the iliosacral screw technique and the compromised L5 pedicle preventing lumbopelvic fixation, the patient underwent an innovative Hula Hoop technique described here. Using the Hula Hoop technique, a technique that has rarely been studied in humans, we avoided an invasive open procedure, decreased anesthesia time, reduced the size and number of incisions, and minimized bleeding. After three months of routine physiotherapy and occupational therapy, the patient was able to walk with a walker and an ankle-foot orthosis.

Open fixation of the posterior malleolus increases the morbidity of trimalleolar ankle fracture fixation. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2022:10.1007/s00590-022-03455-0.

Abstract
PURPOSE To assess the morbidity of open reduction internal fixation (ORIF) of posterior malleolus fractures (PMFs) in the setting of trimalleolar ankle fractures. METHODS A retrospective review of 79 trimalleolar ankle fractures was performed to identify need for syndesmotic fixation, blood loss, operative/tourniquet time, complications, and reoperations. Patients with PMF ORIF (n = 38) were compared to those with no fixation (n = 41). A subanalysis of patients with small PMFs (< 25%) was performed. RESULTS The PMF ORIF group required less syndesmosis fixation (proportional difference (PD) - 44.6%, 95% confidence interval (CI) - 61.8 to - 23.0%), had more blood loss (MD 20 ml, CI 0-40), longer operative times (MD 53.0 min, CI 35.9-70.1), longer tourniquet times (MD 26 min, CI 4-33), and had no difference in postoperative joint step-off or concentrically reduced joints. The PMF ORIF group had more postoperative complications (PD 26.9%, CI 6.3-44.8%) and a trend for more reoperations (PD 13.6%, CI -3.4 to 29.6%). Wound complications were more common in the PMF ORIF group (PD 26.5%, CI 6.9-43.6%), resulting in 5 (16.1%) irrigation and debridement procedures. On analysis of patients with small PMFs (n = 42), PMF ORIF (n = 15) resulted in longer operative/tourniquet times and had no observed difference in postoperative joint step-off, concentrically reduced joints, need for syndesmotic fixation, blood loss, or complications/reoperations. CONCLUSION PMF ORIF in the setting of trimalleolar ankle fractures was associated with increased operative/tourniquet times, blood loss, wound complications, and did not eliminate the need for syndesmosis fixation.

Abstract
OBJECTIVE To explore clinical effect of double plate technique in treating Neer 3 to 4 partial fractures of proximal humerus. METHODS From May 2018 to December 2020, 38 patients with proximal humeral classified to Neer 3 to 4 partial fractures were treated with double plate technique and long head tendon fixation of biceps brachii, including 23 males and 15 females, aged from 41 to 89 years old with an average of (67.00 ± 9.76) years old;23 patients classified to Neer 3 fracture, 15 classified to Neer 4 fracture;the time from injury to operation ranged from 5 to 12 days with an average of (8.00±2.86) days. Degree of pain was evaluated by numerical rating scale(NRS) on the third day after operation; change of height of humeral head and angle of humeral neck stem were measured and compared between 2 days and 1 year after operation. Neer score was used to evaluate recovery of shoulder joint after operation at 1 year after operation. RESULTS All 38 patients were followed up for 12 to 19 months with an average of (14.00±1.59) months. NRS score at 3 days after operation was (1.95±0.73) points. Fracture healing time ranged from 2.2 to 3.2 months with an average of(2.60±0.27) months. There were no significant difference in the height of humeral head and angle of humeral neck trunk between two days and 1 year after operation(P>0.05). Four Neer 4 fracture patients occurred absorption of greater tubercle of humerus and partial cystic change of humeral head, but the activity function of shoulder joint was good. Postoperative Neer score at 1 year was 89.50±5.19, and 20 patients got excellent results, 16 good, and 2 moderate. CONCLUSION Double plate technique and long head tendon fixation of biceps brachii were used to treat Neer 3 to 4 fractures of proximal humerus has good clinical effect, and postoperative pain was mild, without special instruments.

Abstract
OBJECTIVE To explore clinical effect of lateral locking compression plate combined with medial buttress plate in treating osteoporotic comminuted fractures of proximal humerus. METHODS From May 2017 to December 2021, 12 patients with osteoporotic comminution of proximal humerus were treated by lateral locking compression plates combined with medial buttress plates, including 5 males and 7 females, aged from 55 to 78 years old, bone mineral density(BMD) less than -2.5 g/cm3, the time from injury to operation was from 2 to 6 days. According to Neer classification, 7 patients were type Ⅲ, 4 patients were type Ⅳ and 1 patient was type Ⅵ. Postoperative complications, fracture healing and internal fixation were observed and Constant-Murley score of shoulder joint was used to evaluate clinical effects at 6 months after operation. RESULTS Postoperative wound healed well at stage I. All patients were followed up from 6 to 18 months. Humeral head collapse and necrosis occurred in 1 patient and humeral head varus in 1 patient. No impact of shoulder joint, internal fixation loosening occurred. Constant-Murley score at 6 months ranged from 45 to 90 points, and 6 patients got excellent result, 3 good, and 3 poor. CONCLUSION Locking compression plate combined with medial buttress plate could effectively reconstruct medial humeral column support and enhance fracture stability, and receive satisfactory clinical results. However, no control group was established in this study, and function of shoulder joint has not been evaluated many times after operation, so it cannot dynamically reflect changes of shoulder joint function.

Abstract
PURPOSE To compare functional outcomes, complication rates, and survival in patients with intertrochanteric fracture treated with percutaneous compression plate (PCCP) or gamma nail (GN). METHODS A retrospective study of prospectively collected data of patients treated with PCCP or GN for AO/OTA 31.A1 or AO/OTA 31.A2 fractures was conducted. Sixty-eight consecutive patients treated with PCCP between 2018 and 2020 were enrolled and matched with 68 patients with comparable characteristics treated with GN. The activities of daily living (ADL) index and specific scales for walking ability and need for walking aids at 4 months and 1 year after fracture fixation were chosen as primary outcomes. Postoperative complications and one-year survival were recorded and compared between the two groups. RESULTS Walking ability and ADLs index decreased and the need for walking aids increased in both groups compared to the prefracture state at both follow-up intervals (p < 0.001), regardless of the treatment received. There was no difference between the two implants in the rate of implant-related complications. One-year survival rate was 78.9% (95% CI 67.0-86.9) and 82.4% (95% CI 71.0-89.5) in patients undergoing PCCP or GN, respectively, with no significant difference between the two groups. CONCLUSIONS Walking ability, ADLs, complication rate, and 1-year survival are not significantly different when patients undergoing PCCP or GN are compared. The choice of implant may not be decisive for the outcome of treatment of intertrochanteric fractures, provided that stable fixation is ensured.

Abstract
Purpose Management of pediatric subtrochanteric femur fractures (SFFs) is difficult. The aim of this study was to evaluate the outcomes of adolescent SFFs treated with adult proximal humeral locking plates (PHLPs). Materials and Methods A retrospective analysis of 18 adolescents (11 male, 7 female) with a diagnosis of SFF who underwent internal fixation with a PHLP was conducted. Data regarding injury mechanism, fracture pattern, and time to union were recorded for all patients. In addition, a clinical and functional evaluation of patients was performed using the Harris hip score (HHS), Iowa hip score (IHS), modified Merle d'Aubigne-Postel score (MMAPS), Flynn criteria, and hip range of motion (ROM). Results The mean age of the patients was 12.72±2.05 years (range, 10-16 years). Radiological observation was performed for evaluation of five different injury mechanisms and different fracture patterns in patients. The mean postoperative HHS was 92.27±5.61, the mean IHS was 90.88±6.46, and the mean MMAPS was 17.22±0.94. According to the Flynn criteria, excellent results were achieved in 14 cases and satisfactory results were obtained in four cases. Measurements of the patients' mean hip ROM values were as follows: 17.77±3.52° in extension, 115.27±6.74° in flexion, 43.05±3.48° in abduction, 27.50±4.28° in adduction, 42.22±4.60° in internal rotation, and 42.22±3.91° in external rotation. Conclusion Surgery performed on adolescent patients using an adult PHLP showed good, safe results. Therefore, it should be considered as an alternative option.

Abstract
A fracture of the affected extremity in patients with Klippel-Trenaunay-Weber syndrome can be fatal due to massive bleeding and show poor results. A 42-year-old male presented with an old fracture of the right femoral shaft with metal failure. We planned an operation to remove the previously fixed plate and to perform re-fixation using an intra-medullary nail. Preoperative angiography was performed and the arteriovenous malformations were embolized in order to reduce the risk of bleeding. After angiography, the previously fixed plate was removed. After the operation, a second angiography was performed immediately and the venous malformation was embolized. One week after the first operation, a second operation was performed in order to reduce the fracture and to perform re-fixation using an intramedullary nail. The patient is being followed without major complication over a period of seven years after surgery. We recommend careful planning of preoperative and postoperative angiography and embolization in order to reduce the risk of bleeding in patients with Klippel-Trenaunay-Weber syndrome.

Abstract
BACKGROUND Wire cerclages play a fundamental role in fracture fixation. With an increasing variety of designs being commercially available the question arises which cerclage should be used. This study investigates the biomechanical properties of metallic and non-metallic cerclages and their different application-types. Furthermore, potential influence of muscular interposition between bone and cerclage constructs was tested. METHODS Samples of the following four different cerclage types were tested on 3D printed models of human humeri as well as on human cadaveric humeri with and without muscular interposition: Titanium Cable Cerclage (CC), Steel Wire Cerclage (SWC), Suture Tape (ST), Suture Tape Cerclage (STC) with both single- (sSTC) and double-loop application (dSTC). A preinstalled self-locking mechanism secured by the provided tensioner in the STCs being the main difference to the STs. Cyclic loading was performed to 1 kN and then linearly to a maximum load of 3 kN. Statistical analysis was performed using either one-way ANOVA and post-hoc Tukey or Kruskal-Wallis and post-hoc Dunn test depending on normalization of data (p < 0.05). RESULTS Whilst all cerclage options could withstand high loads during failure testing, only within the CC and dSTC group, all samples reached the maximal testing load of 3000 N without any failure. The SWC reached 2977.5 ± 63.6 N, the ST 1970.8 ± 145.9 N, and the sSTC 1617.0 ± 341.6 N on average. Neither muscular interposition nor bone quality showed to have a negative influence on the biomechanical properties of the cerclage constructs, presenting no significant differences. CONCLUSION All tested cerclage constructs produce reliable stability but differ in their resulting compression forces, in a simplified fracture model. Therefore, non-metallic cerclage alternatives can provide similar stability with less compression and stiffness to metallic cable constructs, but they may offer several advantages and could possibly provide future benefits. Especially, by offering more elasticity without losing overall stability, may offer a biologic benefit. Installing any cerclage constructs should be performed carefully, especially if poor bone quality is present, as the tightening process leads to high forces on the construct.

Abstract
BACKGROUND Treating panfacial fractures (PFFs) can be extremely difficult even for experienced surgeons. Although several authors have attempted to systemize the surgical approach, performing surgery by applying a unidirectional sequence is much more difficult in practice. The purpose of this study was to review the literature on PFF surgery sequence and to understand how different surgical specialists-plastic reconstructive surgery (PRS) and oral maxillofacial surgery (OMS)-chose sequence and review PFFs fixation sequence in clinical cases. METHODS The PubMed and Google Scholar databases were scoured for publications published up until May 2020. Data extracted from the studies using standard templates included fracture part, fixation sequence, originating specialist, and the countries. Bibliographic details like author and year of publication were also extracted. Also, we reviewed the data for PFFs patients in the Trauma Registry System of Dankook University Hospital from 2011 to 2021. RESULTS In total, 240 articles were identified. This study comprised 22 studies after screening and full-text analysis. Sixteen studies (12 OMS specialists and 4 PRS specialists) used a "bottom-top" approach, whereas three studies (1 OMS specialist and 2 PRS specialists) used a "top-bottom" method. However, three studies (only OMS specialists) reported on both sequences. In our hospital, there were a total of 124 patients with PFF who were treated during 2011 to 2021; 64 (51.6%) were in upper-middle parts, 52 (41.9%) were in mid-lower parts, and eight (6.5%) were in three parts. CONCLUSION Bottom-top sequencing was mainly used in OMS specialists, and top-bottom sequencing was used at a similar rate by two specialists in literature review. In our experience, however, it was hard to consistently implement unidirectional sequence suggested by a literature review. We realigned the reliable and stable buttresses first with tailoring individually for each patient, rather than proceeding in the unidirectional sequence like bottom-top or top-bottom.

Abstract
The use of 3D printing in orthopedic trauma is supported by clinical evidence. Existing computed tomography (CT) data are exploited for better stereotactic identification of morphological features of the fracture and enhanced surgical planning. Due to complex logistic, technical and resource constraints, deployment of 3D printing is not straightforward from the hospital management perspective. As a result not all trauma surgeons are able to confidently integrate 3D printing into the daily practice. We carried out an expert panel survey on six trauma units which utilized 3D printing routinely. The most frequent indications are acetabular and articular fractures and malalignments. Infrastructure and manpower structure varied between units. The installation of industrial grade machines and dedicated software as well as the use of trained personnel can enhance the capacity and reliability of fracture treatment. Setting up interdisciplinary jointly used 3d printing departments with sound financial and management structures may improve sustainability. The sometimes substantial logistic and technical barriers which impede the rapid delivery of 3D printed models are discussed.

Abstract
BACKGROUND There appears to be a paucity of knowledge about the biomechanics of locking plates for the fixation of metacarpal shaft fractures. A thorough understanding of the biomechanics of locking plates is needed to apply them correctly, optimize outcomes, and avoid complications. The purpose of this study is to investigate the biomechanics of the fixation of metacarpal fractures using locking plate-screw constructs with different numbers of screws. HYPOTHESIS The difference in the number of screws in the locking plate influenced the biomechanical outcome of the metacarpal fracture. METHODS Finite element models of third metacarpal fractures with locking plate-screw constructs were established, and the magnitude and distribution of their stresses and displacements were investigated when a vertical load of 100N was applied. RESULTS For the metacarpal fracture with a locking plate and screws, the stress in the metacarpal was largely shared by the plate-screw construct. For the plate-screw construct, the stress is concentrated in the area close to the fracture line, and the 6-screw Group has the lowest failure risk since it has the lowest plate stress and the second-lowest screw stress. The implant-bone construct with 8 screws has better biomechanical stability because of minimal displacement, but increased stress on both the metacarpal bone and the screws, leading to increased failure rates. DISCUSSION The stresses in the metacarpal were mostly shared by the plate-screw constructs and the screws closest to the fracture line were the most likely to break or loosen. For the implant-bone constructs, the locking plate with 2 screws was the most vulnerable to break or loosen, whereas the locking plate with 6 screws was the least likely to break or loosen. The implant-bone construct with 8 screws had better biomechanical stability, but the stresses in both the metacarpal and the screws were increased, which increased the risk of failure. LEVEL OF EVIDENCE IV, basic science study.

Abstract
STUDY DESIGN A retrospective cohort study of patients with surgically treated thoracolumbar fractures. PURPOSE This study aimed to describe the incidence of adverse events (AEs) after surgical stabilization of thoracolumbar spine injuries and to identify predictive factors for the occurrence of AEs. OVERVIEW OF LITERATURE Thoracolumbar spine fractures are frequently present in patients with blunt trauma and are associated with significant morbidity. AEs can occur due to the initial spinal injury or secondary to surgical treatment. There is a lack of emphasis in the literature on the AEs that can occur after operative management of thoracolumbar fractures. METHODS We performed a retrospective review of 199 patients with surgically treated thoracolumbar fractures operated between January 2007 and January 2018. The potential risk factors for the development of AEs as well as the development of common complications were evaluated by univariate analysis, and a multivariate logistic regression analysis was performed to identify independent risk factors predictive of the above. RESULTS The overall rate of AEs was 46.7%; 83 patients (41.7%) had nonsurgical AEs, whereas 24 (12.1%) had surgical adverse events. The most common AEs were urinary tract infections in 43 patients (21.6%), and hospital-acquired pneumonia in 21 patients (10.6%). On multivariate logistic regression, a Thoracolumbar Injury Classification and Severity (TLICS) score of 8-10 (odds ratio [OR], 6.39; 95% confidence interval [CI], 2.33-17.51), the presence of polytrauma (OR, 2.64; 95% CI, 1.17-5.99), and undergoing open surgery (OR, 2.31; 95% CI, 1.09-4.88) were significant risk factors for AEs. The absence of neurological deficit was associated with a lower rate of AEs (OR, 0.47; 95% CI, 0.31-0.70). CONCLUSIONS This study suggests the presence of polytrauma, preoperative American Spinal Injury Association score, and TLICS score are predictive of AEs in patients with surgically treated thoracolumbar fractures. The results might also suggest a role for minimally invasive surgical methods in reducing AEs in these patients.

Injury 2022; 53:3904-3911. [PMID: 36182591 DOI: 10.1016/j.injury.2022.09.037] [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: 07/15/2022] [Revised: 09/15/2022] [Accepted: 09/22/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVES We have proposed a novel intramedullary nail (Ni-Nail) by incorporating a sustentaculum tali screw to improve the fixation stability of minimally invasive treatment for calcaneal fractures. This study aimed to evaluate the biomechanical characters of the Ni-Nail system and compare it with traditional C-Nail system. METHODS A finite element model of a Sanders type-IIIAB calcaneal fracture was reconstructed and fixed using two intramedullary nail systems, which was validated by a cadaver study. A vertical loading of 700 N was applied to the subtalar joint surfaces, and 525 N Achilles tendon tension was applied to the superior border of the Achilles tuberosity. The von Mises stresses and fracture displacements of both fixation models were evaluated. RESULTS The maximum von Mises stress of the screws of Ni-Nail and C-Nail were 27.92 MPa and 57.42 MPa, respectively, while that of the main nail were 67.44 MPa and 53.01 MPa. In addition, the maximum fracture displacement of the Ni-Nail was larger than that of C-Nail by 15.6% (0.37 mm vs.0.32 mm). CONCLUSIONS Our static simulation analysis showed that both Ni-Nail and C-Nail demonstrated similar biomechanical stability for calcaneal fixation. The Ni-Nail features a simple structure that is easier to operate and less traumatizing. Future studies may consider to further evaluate the clinical effectiveness by clinical trials and follow-ups.

Abstract
Background Retrograde nailing of proximal femoral shaft fractures is controversial. The purpose of this study was to compare patients with proximal femur fractures undergoing antegrade versus retrograde intramedullary nailing (AIMN vs RIMN) and determine the safety and efficacy of RIMN. Methods A retrospective review was performed on 54 patients undergoing femoral IMN for proximal femoral shaft fractures at an urban level one trauma institution between January 2016 and July 2021.Fracture distance from the lesser trochanter (LT) was recorded and used to calculate the number of cortical diameters (NCD) from the LT. Proximal femur fractures were defined as < 3 NCD. AIMN and RIMN fixation was utilized in 31 (57.4%) and 23 (42.6%) patients, respectively. Outcomes measures included pre-/postoperative true translational and angular displacement (TTD and TAD), operative time, estimated blood loss (EBL), union rate, time to union, complications, and reoperations. Results AIMN and RIMN groups were similar in terms of age, sex, BMI, tobacco use, diabetes, ASA classification >2, AO/OTA classification, preoperative TTD or TAD, open fractures, or ballistic fractures. The AIMN group, had a shorter measured distance from the LT (47.0 vs. 66.1 mm, p = 0.04) but the difference in NCD was not significant (1.4 vs. 2.0, p = 0.07). Among patients with isolated IMN procedures, the RIMN group had shorter operative times (142.3 vs. 178.5 min, p = 0.01) and less EBL (100 vs. 250 mL, p = 0.008). There was no observed intergroup difference in terms of postoperative TTD/TAD, union rate, time to union, complications, or reoperations. Conclusion RIMN is a viable treatment option for proximal femoral shaft fractures that results in less operative time, less blood loss, and no detectable differences in union, reoperations, or complications. Level of evidence Level III, Retrospective cohort study.

Abstract
OBJECTIVES Recently a modified high-submandibular approach (HSMA) has been introduced for treatment of condylar fracture. This approach involves an incision line close to the mandibular angle and transmasseteric transection, leading to a low incidence of facial palsy and allowing good visualization of the condyle area, especially the condylar neck and subcondyle positions. This study reports several cases managed with this modified HSMA technique for treating condylar fractures. MATERIALS AND METHODS Six cases of condylar fractures treated with modified HSMA technique were reviewed. RESULTS Three unilateral subcondylar fracture, 1 bilateral subcondylar fracture, 1 unilateral condylar neck fracture, 1 unlateral simultaneous condylar neck and subcondylar fracture cases were reviewed. All the cases were successfully treated without any major complication. CONCLUSION Reduction, fixation, and osteosynthesis of condylar fractures via the modified HSMA technique enabled effective and stable treatment outcomes. Therefore, the described approach can be used especially for subcondylar and condylar neck fractures with minimal complications.

Comparison between headless compression screws and tension band wires for the fixation of medial malleolar fractures: a prospective randomized trial. Arch Orthop Trauma Surg 2022; 142:2627-2633. [PMID: 34160673 DOI: 10.1007/s00402-021-04003-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Accepted: 06/14/2021] [Indexed: 10/21/2022]
Abstract
INTRODUCTION To date, there has been no prospective randomized trial supporting the rationale of the use of headless compression screw (HCS) compared to conventional fixation methods for medial malleolar fractures. This study aimed to prospectively compare the outcomes of the HCS and tension band wire (TBW) for the fixation of medial malleolar fractures. MATERIAL AND METHODS Sixty patients were randomized to receive either an HCS or a TBW for the fixation of a medial malleolar fracture. Clinical outcomes were assessed using the Olerud-Molander ankle score (OMAS), EuroQoL five-dimensional instrument (EQ-5D) score, visual analog scale (VAS) score, patient satisfaction with implant-related symptoms, operative time, and incision length. Radiographic outcomes were assessed using the presence of nonunion, delayed union, and articular incongruity. Clinical and radiographic assessments were performed at 2 and 6 weeks and 3, 6, and 12 months postoperatively. RESULTS The OMAS, EQ-5D score, VAS score, and operative time did not differ between the HCS and TBW groups; however, the HCS group had greater satisfaction with implant-related symptoms and smaller incision than the TBW group. There was no difference in the presence of nonunion, delayed union, and articular incongruity. CONCLUSION HCS fixation for medial malleolar fractures is not inferior to TBW fixation, while reducing implant-related symptoms. These findings suggest that HCS is a viable alternative for the fixation of medial malleolar fractures.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2022; 123:e619-e625. [PMID: 35202862 DOI: 10.1016/j.jormas.2022.02.009] [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: 11/17/2021] [Revised: 12/22/2021] [Accepted: 02/16/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Lateral midface fractures occasionally require open reduction and internal fixation to restore function and facial symmetry. However, some patients retain facial asymmetry despite undergoing surgery due to hard tissue displacement or soft tissue sagging. This study aimed to determine the influence of soft tissue sagging on the postoperative facial symmetry. METHODS We examined the medical records of 590 patients who underwent planned plate removal after lateral midface or zygomatic bone fractures. After applying the inclusion and exclusion criteria, we analyzed 106 cases of lateral midface fractures for hard tissue displacement and soft tissue sagging using pre- and postoperative radiological imaging and postoperative face scanning. RESULTS We observed significantly larger soft tissue sagging (p < 0.001) and hard tissue displacement (p = 0.006) on the fractured side than on the non-fractured side. There was no correlation between differences in the soft tissue sagging and those in the hard tissue displacement (|rho|=0). Linear regression analysis showed no statistical influence of sex or age group on the soft tissue sagging and hard tissue displacement. CONCLUSION Therefore, we recommend treating soft tissue sagging as a discrete aspect of midfacial fracture treatment to achieve optimal postoperative facial symmetry. From a clinical perspective, we recommend better soft tissue management during open fracture treatment than focusing mainly on the reduction of bony hard tissues.

Abstract
Background Hip fractures are common in elderly populations and can be life threatening. Changes in healthcare delivery and outcomes for patients with hip fracture treated with intramedullary nails are not well characterized. The objectives of our study were: 1) the characterization of patients treated with the Trochanteric Fixation Nail -Advanced™(TFNA) Proximal Femoral Nailing System or comparable nails (index) and estimate 12-month all-cause readmissions (ACR) and reoperations following index; and 2) the evaluation of 10-year healthcare utilization (HCU) trends for treatment of femoral fractures with femoral nails. Methods This is a retrospective database analysis using the Premier hospital database. All adults with femoral fracture treated with an intramedullary nail, from 2010 to Q3 2019, in the inpatient setting, were identified. Exclusion criteria included patients with bilateral hip surgery and presence of breakage at time of initial surgery. The primary outcome was ACR and reoperation, the secondary outcomes were healthcare utilization metrics. Variables included demographics, comorbidities (Elixhauser Index (EI)), surgical intervention variables and hospital characteristics. Results Forty-one thousand one hundred four patients were included in the study, of which 14,069 TFNA patients, with average age 77.9 (Standard deviation (SD): 12.0), more than 60% with 3 or more comorbidities (more than 64% for TFNA), 40% with severe or extreme disease severity and one third with severe or extreme risk for mortality. ACR reached 60.1% (95% confidence interval (CI): 59.6%-60.5%) – for TFNA: 60.0% (95%CI: 59.2%-60.8%). The reoperation rate was 4.0% (95%CI: 3.8%-4.2%) – for TFNA: 3.8% (95%CI: 3.5%-4.1%). Length of stay (LOS) averaged 5.8 days (SD: 4.8), and 12-month hip reoperation was 4.0% (3.8%-4.2%), in TFNA cohort: 3.8% (3.5%-4.1%). From 2010 to 2019: the percentage patients operated within 48 h of admission significantly increased, from 75.2% (95%CI: 74.3%-76.1%) to 84.3% (95%CI: 83.9%-84.6%); LOS significantly decreased, from 6.2 (95%CI: 6.0–6.4) to 5.6 (95%CI: 5.5–5.7) days; discharge to skilled nursing facilities (SNF) increased from 56.0% (95%CI: 54.8%-57.2%) to 61.5% (95%CI: 60.8%-62.2%); ACR rates decreased but reoperation rates remained constant. Conclusions ACR and reoperation rates were similar across device types and averaged 60.1% and 4.0%, respectively. Ten-year analyses showed reductions in hospital HCU and greater reliance on SNF.

Abstract
Objective To analyze the use of packed red blood cells (PRBCs) for patients with pelvic fracture and evaluate factors associated with PRBC transfusion for patients with pelvic fracture. Methods This retrospective cohort study collected 551 patients with pelvic fractures from six hospitals between September 1, 2012, and June 31, 2019. The age span of patients varied from 10 to 95 years old, and they were classified into two groups based on high‐energy pelvic fractures (HE‐PFs) or low‐energy pelvic fractures (LE‐PFs). The study's outcome was the use of PRBCs, fresh frozen plasma (FFP), and albumin. Demographic data, characteristics, laboratory tests, clinical treatment details, and clinical outcomes were compared between the two groups. Factors that were statistically associated with perioperative PRBCs in univariate analyses were included to conduct an optimal scale regression to determine the independent factors for perioperative PRBCs. Results A total of 551 patients were screened from six hospitals, and after inclusion and exclusion, 319 were finally included and finished the follow‐up from admission to discharge, while four patients died during hospitalization. Three hundred and nineteen patients were classified into two groups by their injury mechanisms. A total of 230/319 (72.1%) patients were classified into the HE‐PF group, and 89/319 (27.8%) patients were classified into the LE‐PF group. Patients in the HE‐PF group were transfused with 4.5 (3–8) units of PRBCs, 300 (0–600) ml of FFP, and 0 (0–30) g of albumin, while patients in the LE‐PF group were transfused with 3.5 (2–4.5) units of PRBCs, 0 (0–295) ml of FFP, and 0 (0–0) g of albumin (all P < 0.001). There were higher proportions of male patients and patients under 65 in the HE‐PF group (all P < 0.001). HE‐PF group patients were more severely injured and likely to take external fixation. The optimal scale regression revealed four significant factors associated with perioperative transfused PRBCs, which were patients on admission with hemorrhagic shock (importance = 0.283, P = 0.004), followed by fracture types identified by Tile classification (importance = 0.156, P < 0.001), hemoglobin levels below 70 g/L on admission (importance = 0.283, P = 0.004), followed by fracture types identified by Tile classification (importance = 0.156, P < 0.001), hemoglobin levels below 70 g/L on admission (importance = 0.148, P = 0.039), and methods of pelvic fixation (importance = 0.008, P = 0.026), ranked by the importance. Conclusion Patients with HE‐PFs had increased transfusions of PRBCs, FFP, and albumin, and hemorrhagic shock on admission, Tile classification, Hb levels, and stabilization methods were found to be associated with perioperative PRBCs.

Abstract
The management of polytrauma patients is a complex multidisciplinary and dynamic task. The early and comprehensive assessment of the clinical condition is of great importance with respect to the timing and the individual decision-making on surgical fracture treatment. Stable patients benefit from early definitive fracture treatment, whereas for unstable patients, the concept of multistage fracture treatment with temporary minimally invasive stabilization has gained wide acceptance. These concepts, known as early total care (ETC) and damage control orthopedics (DCO), have been extended in recent decades by dynamic and injury-adapted treatment protocols, such as early appropriate care (EAC) or safe definitive orthopedic surgery (SDS): Therefore, patients in an initially unclear condition (borderline patients) can now also be treated with an individually adapted care concept as soon as possible.

Abstract
OBJECTIVE To evaluate clinical efficacy of single-tunnel double-line technique with tendoscopy in treating tibial intercondylar eminence fractures. METHODS From January 2016 to April 2020, 22 patients with tibial intercondylar eminence fractures were admitted, including 14 males and 8 females with a mean age of (34.8±5.9) years old ranging from 26 to 45 years old. The mean duration from injury to surgery was(11.2±4.1) days(ranged, 5 to15 d). All patients were treated with arthroscopic single-tunnel double-line technique. The fracture healing was evaluated according to X-ray. The Lysholm score, IKDC 2000 score and the anterior drawer test were used to evaluate efficacy before operation and at the latest follow-up. RESULTS All patients were followed up, and the duration ranged from 12 to 75 months, with an average of(34.6±13.0) months. Lysholm score was (89.60±2.89) points at the latest follow-up, showing significant difference when compared with preoperative score which was (30.80±9.55)points(t=9.67, P<0.01). IKDC 2000 score was(80.00±6.17) points at the latest follow-up, showing significant difference when compared with preoperative score which was(24.60±7.21)points(t=11.41, P<0.01). One patient showed weakly positive of drauer test. CONCLUSION Single-channel double-line technique could effectively fix bone block of intercondylar eminence with advantage of easy operation and minimally invasive, which could be applied to various types of tibial intercondylar eminence fractures.

Abstract
BACKGROUND Displacement of the lesser trochanter (LT) is not uncommon after managing intertrochanteric femoral fractures and the influence of nonunion of the LT-fragment on clinical outcomes remains controversial. This study aimed to investigate the relationship between the displacement distance and union of the LT-fragment and evaluate the influence of LT-fragment nonunion on hip function and complications. METHODS This retrospective study included patients with intertrochanteric fractures and displaced LT treated with intramedullary fixation at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from June 2015 to July 2017. The patients were grouped as union and nonunion of the LT-fragment at 1 year. The LT-fragment displacement distance of LT was measured by the anterior-posterior radiographs. RESULTS Thirty-one and 22 patients showed union and nonunion at 1 year, respectively. The nonunion group had a higher postoperative complication rate than the union group (59% vs. 29%, P = 0.047), especially mechanical complications (45% vs. 6%, P = 0.001). There was no significant difference in hip function between the two groups (P > 0.05). The receiver operating characteristic (ROC) curve revealed an area under the curve of 0.933 of displacement ratio. Patients with a displacement ratio > 0.35 were more likely to have nonunion of the LT-fragment. CONCLUSIONS The displacement ratio might be a reliable predictor of LT-fragment union. The incidence of postoperative complications might increase with LT-fragment nonunion.

Abstract
Background Periprosthetic tibial fractures in Total Knee Arthroplasty are much less commonly seen than femoral fractures, and there is a paucity of available literature and management recommendation for these fractures. We aimed to identify the relevant and up-to-date literature on this subject to analyse the incidence, risk factors, and management recommendations. Methods A literature search was done on the databases of PubMed and SCOPUS using appropriate keywords. All the published literature in the English language was included for this review. Results We included 21 studies comprising 260 tibial periprosthetic fractures (91 intra-operative (35%) and 169 (65%) post-operative or delayed fractures). Only 5.9% of these fractures were managed conservatively. Whereas 98 cases (58%) were managed with open reduction and internal fixation (ORIF) with plating, 19 (11.2%) were managed with revision TKA. Seventeen cases (10%) were managed with minimally invasive percutaneous plate osteosynthesis (MIPPO), and 8 (4.7%) were managed with intramedullary nailing. Less than 6% of cases were managed with other means, viz. megaprosthesis (n = 4), arthrodesis (n = 5), amputation (n = 1), and external fixator (n = 1). Conclusion Intraoperative fractures accounted for one-third of the fractures in our review. A majority of the delayed periprosthetic fractures were treated with surgical intervention. The most preferred surgical treatment method was ORIF of fractures using locking plates (either open or MIPPO). Revision TKA or megaprosthesis was used in cases with the loosened implants in association with the fracture. Level of evidence IV.
