- Abstract
Summary: Reconstruction of large soft-tissue defects of an upper extremity is very challenging due to the unavailability of expendable local muscle. Appropriate soft-tissue restoration is an essential component of such reconstruction treatment protocols, and often requires a vascularised flap to protect the exposed neurovascular and musculotendinous structures. The latissimus dorsi muscle makes an ideal pedicled flap because of its long neurovascular pedicle, large size, ease of mobilisation and expendability. Moreover, the flap provides well-vascularised tissue from a region far from the area of injury. This paper describes the technique for pedicle latissimus dorsi flap transfer and also reports the authors' experience of its application for the acute treatment of massive upper-extremity soft-tissue injuries. 20 patients with large soft-tissue defects over the upper extremity caused by trauma and infection underwent aggressive debridements and immediate soft-tissue reconstruction using a pedicled latissimus dorsi muscle flap. Successful reconstructions were achieved and primary healing of wounds occurred in all patients, with minor complications. The donor site morbidity was minimal. At a mean of 3.6 years' follow-up (range: 1.5-6 years), all functional results were good and the patients were satisfied with their outcomes. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Study Design: A single-centre, retrospective cohort study., Objectives: To compare the clinical outcomes between nail-plate constructs and the plate-on-plate technique in the treatment of proximal femoral peri-implant fracture (PFPIF)., Methods: Thirty-seven patients with PFPIF treated at our hospital were included. All patients underwent at least 1-year follow-up. Imaging studies and medical records, including walking ability, complications, and functional outcomes 1 year after surgery, were thoroughly reviewed., Results: Twenty patients were treated with nail-plate constructs. Seventeen patients were treated with the plate-on-plate technique. The average surgical times in the plate-on-plate technique and nail-plate construct groups were 119.4 ± 23.4 min and 246.3 ± 48.0 min, respectively. The average blood losses in the plate-on-plate technique and nail-plate construct groups were 124.7 ± 41.6 mL and 434.3 ± 170.8 mL, respectively. The plate-on-plate technique group had a significantly shorter surgical time and less blood loss than the nail-plate construct group. No statistically significant differences were found in union time, ambulation status, 36-item Short Form Health Survey score, and complication rate between the two groups., Conclusion: The plate-on-plate technique can be considered an alternative option to reduce operation time and blood loss in the treatment of PFPIF, especially for older patients and those who are less capable of sustaining long-term operation and anaesthetic exposure., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier Ltd.

- Abstract
Introduction: Early definite treatment for orthopedic patients is strongly advocated. However, a consensus has not been reached on the optimal timing of long bone fracture fixation for patients with associated mild traumatic brain injury (TBI). Surgeons lack evidence on the basis on which they should decide on the operation timing., Methods: We retrospectively reviewed the data of patients with mild TBI and lower extremity long bone fractures from 2010 to 2020. The patients receiving internal fixation within and after 24 h were defined as the early- and delayed-fixation groups. We compared the discharge Glasgow Coma Scale (GCS) scores, lengths of stay, and in-hospital complications. Propensity score matching (PSM) with multiple adjusted variables and a 1:1 matching ratio was applied to reduce selection bias., Results: In total, 181 patients were enrolled; 78 (43.1%) and 103 (56.9%) patients received early and delayed fracture fixation, respectively. After matching, each group had 61 participants and were statistically identical. The delayed group did not have better discharge GCS scores (early vs. delayed: 15.0 ± 0 vs. 15.0 ± 0.1; p = 0.158). The groups did not differ in their lengths of hospital stay (15.3 ± 10.6 vs. 14.8 ± 7.9; p = 0.789), intensive care unit stay (2.7 ± 4.3 vs. 2.7 ± 3.8; p = 0.947), or incidence of complications (23.0% vs. 16.4%; p = 0.494)., Conclusions: Delayed fixation for patients with lower extremity long bone fractures concurrent with mild TBI does not result in fewer complications or improved neurologic outcomes compared with early fixation. Delaying fixation may not be necessary to prevent the second hit phenomenon and has not demonstrated any clear benefits., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Introduction: The radiocarpal fracture-dislocations are a spectrum of severe injury involving both the bony and ligamentous structures that stabilise the wrist joint. The aim of this study was to analyse the outcome of open reduction and fixation without volar ligament repair for Dumontier group 2 radiocarpal fracture-dislocation and to evaluate the incidence and clinical relevance of ulnar translation and advanced osteoarthritis., Patients and Methods: We retrospectively reviewed 22 patients with Dumontier group 2 radiocarpal fracture-dislocation treated in our institute. Clinical and radiological outcomes were recorded. Postoperative visual analogue scale (VAS) score for pain, Disabilities of the Arm, Shoulder and Hand Outcome Measure (DASH), and Mayo modified wrist scores (MMWS) were collected. Furthermore, extension‒flexion and supination‒pronation arcs were collected by reviewing chart, either. We divided the patients into two groups according to the presence or absence of advanced osteoarthritis, and presented the differences in the pain, disability, wrist performance, and range of motion between the two groups. We performed the same comparison between the patients with and those without the ulnar translation of the carpus., Results: There were sixteen men and six women with a median age of 23 years (range, 20‒48 years). The median follow-up period was 33 months (range, 12-149 months). The median VAS, DASH and MMWS were 0 (range 0-2), 9.1 (range, 0-65.9) and 80 (range, 45-90), respectively. The median flexion‒extension and pronation‒supination arcs were 142.5° (range, 20°‒170°) and 147.5° (range, 70°‒175°), respectively. Ulnar translation was recognised in four patients and the development of advanced osteoarthritis was noted in 13 patients during the follow-up period. However, neither was highly correlated with functional outcomes., Conclusion: The current study postulated that ulnar translation might occur following treatment for Dumontier group 2 lesions, whereas injury was predominantly caused by rotational force. Therefore, radiocarpal instability should be recognized during the operation. However, the clinical relevance of ulnar translation and wrist osteoarthritis needs to be assessed in further comparison studies., Competing Interests: Declaration of Competing Interests The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2023 Elsevier Ltd.

- Abstract
Introduction: Management of massive tibial bone defects remains challenging for orthopaedic doctors. This study aimed to ascertain the viability and reliability of utilising an ipsilateral vascularised fibula with an external locking plate for the difficult situation., Materials and Methods: Between January 2012 and December 2017, eight patients (7 men) with a mean age of 32.3 (19-54) years who presented with massive tibial bone defects were treated using the described technique. The mean length of the bone defect was 12.4 (8-20) cm. The patients were assessed for clinical and radiographic results, hypertrophy of the fibular graft with DeBoer and Wood's method, and SF-36 functional score., Results: The mean follow-up period was 40.3 (26-60) months. The average time for union was 5.6 (3-8) months. At the final follow-up, all patients had fully united grafts and walked without restriction. The mean graft hypertrophy index was 98.2 %. The SF-36 score was > 75 % in five patients, and 50-75 % in three. Three patients had a leg length discrepancy of > 1.5 cm. Two patients with equinus foot were treated using tibiotalocalcaneal fusion. Three patients had pin-tract infections. Four screws were broken in two cases., Conclusion: Ipsilateral vascularised fibular transfer combined with an external locking plate as a definitive external fixator provides a simple and comfortable treatment, and appropriate mechanical loading and vascularisation of the graft site to achieve hypertrophy of the fibular graft. Hence, our technique can serve as a valuable alternative for the treatment of massive tibial bone defects., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2021.

- Abstract
Background: Having motor impairment since childhood and being at risk of osteoporosis and falls, adults with polio would be more likely to suffer a hip fracture (HF) and may experience different epidemiological characteristics from the general population., Objective: To estimate the risk and incidence of HF in adults with polio., Design: Using a national database, we conducted a population-based cohort study. We identified patients with polio using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code of 138. For each patient with polio, we randomly selected five age- and sex-matched control subjects. Those subjects aged <40 years were excluded. We analyzed participants aged 40˜64 years (middle-aged) and subjects aged ≥65 years (elderly) separately and recognized subjects who had an HF (ICD-9-CM code, 820) only when they received hospitalization to care for the illness from January 1, 2003 to December 31, 2008., Results: We identified 403 adults with polio (mean age ± standard deviation, 47.2 ± 8.6 years). Compared to the controls, patients with polio had a higher incidence of HF (all, 4.1 vs. 1.1/1000 person-years, p = 0.002; middle-aged, 2.3 vs. 0.3/1000 person-years, p < 0.001; male, 6.2 vs. 0.9/1000 person-years, p < 0.001); had a younger mean age (±standard deviation) of fracturing a hip (61.0±14.9 vs. 74.4±9.3 years, p = 0.015); had a lower cumulative HF-free probability (±standard error) before the age of 65 years (0.970±0.017 vs. 0.988±0.007, p<0.001) and throughout the study duration (0.415 ± 0.296 vs. 0.682 ± 0.158, p<0.001); and had a higher risk of HF, yielding an adjusted hazard ratio (95% confidence interval) of 3.58 (1.45˜8.79, p = 0.006). Patients with polio aged >48.2 years were likely to experience an HF., Conclusions: Adults with polio are at risk of HF. A customized HF prevention program is important for people with polio. The program should be started early in middle-age and should include men., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

- Abstract
Objective: In the present retrospective study, we aimed to analyze the results of treatment for recalcitrant distal tibial nonunion using Masquelet technique with locking plate as a definitive external fixator., Materials: We included 15 consecutive cases of distal tibial nonunion treated at our hospital between January 2012 and December 2015. The reconstructive procedure comprised debridement of the nonunion site, deformity correction, stabilization with an external locked plate, defect filling with cement spacer for inducing membrane formation, and bone reconstruction using a cancellous bone autograft (Masquelet technique). All patients were followed-up for at least one year., Results: Fracture union occurred in all cases after a median of 6.5 months (range, 5-12 months). Mean ankle motion ranged from 12.3 (range, 5-20) degrees of dorsiflexion to 35 (range, 5-55) degrees of plantar flexion. At the final follow-up, the median Iowa ankle score was 83 (range, 68-91). Eight patients had excellent scores, six had good scores, and one had fail score., Conclusion: Although the current study involved only a small number of patients and the intervention comprised two stages, we consider that the used protocol is a simple and valuable alternative for the treatment of recalcitrant distal tibial nonunion., (Copyright © 2017 Elsevier Ltd.

- Abstract
Objective: This study aimed to evaluate the outcome of using a metaphyseal locking plate as a definitive external fixator for treating open tibial fractures based on biomechanical experiments and analysis of clinical results., Methods: A metaphyseal locking plate was used as an external fixator in 54 open tibial fractures in 52 patients. The mean follow-up was 38 months (range, 20-52 months). Moreover, static axial compression and torsional tests were performed to evaluate the strength of the fixation techniques., Results: The average fracture healing time was 34.5 weeks (range, 12-78 weeks). At 4 weeks postoperatively and at the final follow-up, the average Hospital for Special Surgery knee score was 85 (range, 81-100) and 94 (range, 88-100), respectively, and the American Orthopaedic Foot and Ankle Society score was 88 (range, 80-100) and 96 (range, 90-100), respectively. Based on the static test result, the axial stiffness was significantly different among groups (p=0.002), whereas the torsional stiffness showed no significant difference (p=0.068)., Conclusions: Clinical outcomes show that the use of locking plate as a definitive external fixator is an alternative choice for tibial fractures after obtaining appropriate fracture reduction. However, external locked plating constructs were not as strong as standard locked plating constructs. Therefore, the use of external locked plating constructs as a definitive treatment warrants further biomechanical study for construct strength improvement., (Copyright © 2016 Elsevier Ltd.

- Abstract
We evaluated both the outcome of using a locking plate as a definitive external fixator for treating open tibial fractures and, using finite element analysis, the biomechanical performance of external and internal metaphyseal locked plates in treating proximal tibial fractures. Eight open tibial patients were treated using a metaphyseal locked plate as a low-profile definitive external fixator. Then, finite element models of internal (IPF) as well as two different external plate fixations (EPFs) for proximal tibial fractures were reconstructed. The offset distances from the bone surface to the EPFs were 6 cm and 10 cm. Both axial stiffness and angular stiffness were calculated to evaluate the biomechanical performance of these three models. The mean follow-up period was 31 months (range, 18-43 months). All the fractures united and the mean bone healing time was 37.5 weeks (range, 20-52 weeks). All patients had excellent or good functional results and were walking freely at the final follow-up. The finite element finding revealed that axial stiffness and angular stiffness decreased as the offset distance from the bone surface increased. Compared to the IPF models, in the two EPF models, axial stiffness decreased by 84-94%, whereas the angular stiffness decreased by 12-21%. The locking plate used as a definitive external fixator provided a high rate of union. While the locking plate is not totally rigid, it is clinically stable and may be advisable for stiffness reduction of plating constructs, thus promoting fracture healing by callus formation. Our patients experienced a comfortable clinical course, excellent knee and ankle joint motion, satisfactory functional results and an acceptable complication rate., (Copyright © 2013 Elsevier Ltd.

- Abstract
The best treatment for unstable proximal femoral fractures is controversial. In this prospective study, we assessed the outcomes of reverse less invasive stabilisation system (LISS) plates for treatment of unstable proximal femoral fractures that are expected to be difficult to nail. From April 2004 to January 2007, 20 patients with unstable proximal femoral fractures that were assessed to be difficult to nail were managed with reverse less invasive stabilisation system-distal femur (LISS-DF) plates, which included (1) subtrochanteric fractures with extension into the piriform fossa, (2) short skeletons with narrow femoral canals, (3) adolescents with open physes and (4) severely bowed or deformed femurs. These patients were enrolled in this study. There were 11 females and nine males, with a median age of 58 years (range, 14-95 years). The average follow-up period was 24 (range, 12-32) months. Functional recovery (Parker and Palmer mobility score), pain, bony union, varus deformity, implant failure and leg length discrepancy were assessed. The fractures united at a median of 7 months (range, 3-15 months) postoperatively. Parker and Palmer mobility scores were 9 points for 17 patients and 6 points for three patients. Pain was absent in 15, mild in three, and moderate in two patients. Patients with poor quality of reduction were more likely to have pain results (p=0.009). Although patients with advanced age were not more likely to have pain results, they were more likely to have 'delayed union' radiographic results (p=0.033). Two limbs were shortened by 1.5 and 2 cm, respectively. Reverse LISS plate fixation led to complete union of unstable proximal femoral fractures without additional procedures. The surgical technique was simple and safe. We recommend considering the use of this locked-plate device as the alternative management of unstable proximal femoral fractures that are unsuitable for nailing procedures., (Copyright 2010 Elsevier Ltd.

- Abstract
High-energy proximal tibial fractures are complex injuries that may lead to significant complications. Staged treatment of these injuries using a spanning external fixator across the knee joint in the acute setting decreases the incidence of complications. This article is a prospective evaluation of outcomes using a two-stage procedure for treatment of 15 patients who sustained open proximal tibial fractures between April 2006 and January 2008. In the first stage, we used low profile, less-invasive stabilisation system (LISS) plates for temporary external fixation to immobilise the fractures after anatomic reduction, followed by soft-tissue reconstruction. In the second stage, we applied LISS plates for definitive internal fixation, using minimally invasive percutaneous osteosynthesis. All fractures were monitored for a mean of 20.4 months (range, 12-32 months). All fractures united at a mean of 38.6 weeks (range, 18-66 weeks). Knee motion ranged from a mean of 1 degrees (range, 0 degrees to 5 degrees ) to 125 degrees of flexion (range, 100 degrees to 145 degrees ). The reduction was scored as good in 13 patients and fair in two patients. At follow-up, 10 patients had excellent, and five had good knee scores. The complications included minor screw-track infections in three patients. In conclusion, the two-stage technique was well suited for treating these difficult injuries, and for patients who needed longer periods of external fixation. Surgeons were able to achieve gross anatomy restoration, soft-tissue reconstruction, stable fixation and high union rates. Patients obtained good-to-excellent motion, function and comfort after treatment., (Copyright 2009 Elsevier Ltd. All rights reserved.)
