Clinical decision making in the assessment and treatment of closed hand fractures: A scoping review.

Introduction: Closed hand fractures represent a significant proportion of emergency department attendances, result in substantial health service utilisation and have a detrimental effect on quality of life. Increasingly, hand therapists in the United Kingdom provide first line fracture treatment. However, the knowledge and skills required to work in such an extended scope capacity have not been elucidated or standardised. This literature review synthesises and reports evidence for the knowledge requisite of clinicians to make evidence-based treatment decisions for patients with hand fractures. Methods: A systematic search was undertaken, using Embase, MEDLINE, PsychInfo and CINAHL electronic databases. Inclusion criteria were English language, full research reports of studies assessing of the reliability or validity of the decision-making process in hand fracture treatment published between 2013 and 2023. Data were summarised narratively. Results: 15 studies met inclusion criteria; most assessed decision making for metacarpal fractures. Studies on imaging (n = 4) suggested the reliability of plain radiograph interpretation of hand fracture characteristics such as angulation is good and similar across various levels of experience. Agreement between surgeons and therapists in choosing surgical or nonsurgical treatment was generally good, but factors influencing decision making remained unclear. No evidence was identified that explored clinical assessment knowledge (subjective or objective patient factors) or the specific competencies required to treat hand fractures. Conclusions: There is limited evidence for the knowledge and skills required of clinicians for the competent assessment and treatment of hand fractures. Stakeholder consensus work is required to develop robust competencies and standardise practice.

Non-Union And Resorption Of Extended Trochanteric Osteotomy And Management Using Modular Tapered Stem In Patient With Extensive Surgical History.

Extended trochanteric osteotomy is an invaluable technique for enhancing femoral exposure during revision total hip arthroplasty. Complications are rarely reported but may include non-union. Even rarer is the incidence of extended trochanteric osteotomy resorption. We present our experience using a modular tapered stem in managing a resorbed extended trochanteric osteotomy following revision total hip arthroplasty in a patient with extensive hip surgical history. Good surgical technique is important in the prevention and management of resorption. It is also important to identify high risk patients such as smokers or those with peripheral vascular disease. Long femoral stem prosthesis with diaphyseal fixation may help in dealing with proximal bone loss due to resorption of an extended trochanteric osteotomy, and avoids the need for allogenic bone graft.

A clinical randomized controlled trail of an intelligent robot-assisted minimally invasive reduction system for treatment of unstable pelvic fractures / 中华创伤骨科杂志

Objective:To compare the short-term efficacy between our self-designed intelligent robot-assisted minimally invasive reduction system and conventional freehand reduction assisted by fluoroscopy in the treatment of unstable pelvic fractures by robot or fluoroscopy-assisted internal fixation with percutaneous screws.Methods:A prospective randomized controlled trial was conducted to include eligible 35 patients with unstable pelvic fracture who were admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from December 2021 to October 2022. They were randomized into 2 groups. The observation group[17 cases, 10 males and 7 females with an age of (44.0±17.4) years] was treated with robot-assisted minimally invasive reduction, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws; the control group[18 cases, 12 males and 6 females with an age of (38.8±15.0) years] was treated with freehand reduction assisted by fluoroscopy, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws. The 2 groups were compared in terms of operation time, intraoperative bleeding, successful reduction, reduction quality, incidence of surgical complications and postoperative functional scores.Results:The 2 groups were comparable because there were no significant differences in the preoperative general data between them ( P>0.05). The intraoperative fluoroscopy frequency[(32.4±17.5) times] and fluoroscopy time [(19.8±10.4) s] in the observation group were significantly lower or shorter than those in the control group [(60.8±26.6) times and (38.2±16.1) s], and the rate of successful reduction in the observation group was 100.0% (17/17), significantly higher than that in the control group[72.2% (13/18)] ( P<0.05). There was no significant difference between the 2 groups in intraoperative bleeding, operation time, reduction error, excellent and good rate of reduction after operation by Matta scoring, or Majeed functional score at 12 weeks after operation ( P>0.05). Conclusion:In the treatment of unstable pelvic fractures, since our self-designed intelligent robot-assisted minimally invasive reduction system can plan autonomously the reduction paths and accomplish minimally invasive reduction of the fracture with 3D images real-time monitoring, it is advantageous over conventional reduction methods in a higher success rate and less radiation exposure.

Fracture-Related infection - the role of the surgeon and surgery in prevention and treatment.

Fracture-related infection (FRI) is a complication that impacts care costs, quality of life, and patient function. Great strides have been made in the last decade to obtain a common language for definition and diagnosis with the contribution of the Fracture-Related Infection Consensus. Although FRI treatment requires the participation of clinical specialists in infectious diseases for the management of antibiotics, it is necessary to understand that this complication is an eminently surgical pathology. The orthopedic surgeon must play a leadership role in the prevention and treatment of this complex disease. In this review, the most relevant aspects of prevention are updated, and a strategy for a sequential and comprehensive approach to the patient with this complication is presented.

Numerical Analyses of Fracture Mechanism of the Pelvic Ring during Side-Impact Load.

The aim of this study is the analysis of the multiple pelvis fracture mechanism in side-impact dynamic load cases. The elaborated numerical model of a pelvis complex includes pelvic and sacral bones as well as soft tissues such as ligaments and cartilages. The bone has been modelled as a viscoelasticity material based on the Johnson-Cook model. The model parameters have been chosen based on the experimental data. The uniqueness of a presented approach refers to the selection of crack criteria for the bone. Thus, it was allowed to analyse the process of multiple fractures inside the pelvic bones. The analysis was evaluated for the model in which the deformation rate influences the bone material properties. As a result, the stress distributions inside particular bones were changed. It has been estimated that the results can vary by 50% or even more depending on the type of boundary conditions adopted. The second step of work was a numerical analysis of military vehicle subjected to an IED. An analysis of the impactor's impact on the pelvis of the Hybrid ES-2RE mannequin was conducted. It was shown that the force in the pelvis exceeds the critical value by a factor of 10. The results of the numerical analysis were then used to validate the model of a military vehicle with a soldier. It was shown that for the adopted loading conditions, the critical value of the force in the pelvis was not exceeded.

DO THE CHANGES OF SCAPULOTHORACIC ANGLE AFFECT WINGED SCAPULA DEVELOPMENT AND FUNCTIONAL SCORES DURING CLAVICLE FRACTURE TREATMENT?

Introduction: To compare surgical and conservative management of midshaft clavicle fractures according with scapulothoracic joint angle change, considering clinical, functional, and radiological outcomes. Methods: A total of 95 midshaft clavicle fracture patients aged between 18-70 years with a minimum follow-up duration of 12 months were included in this study. Patients were treated either conservatively (Group I) or surgically (Group 2). Plane deformities, scapulothoracic joint angle, shortness and isokinetic muscle strength were measured. Shoulder Pain, Disability Index (SPADI) and Short Form-36 (SF36) were assessed. Results: Scapulothoracic joint angles were higher in the conservative treatment group than in surgery group (p=0.036). Consequently, winged scapula was seen more commonly in the conservative treatment group than in the surgery group (p=0.001). Surgical treatment was associated with significantly better SF-36 physical scores and with SPADI pain and disability scores. However, the two groups did not differ in terms of isokinetic muscle strength. Negative anteroposterior plane deformity (p<0.001) and negative axial plane deformity (p=0.004) were more frequent in the conservative treatment group. Clavicle shortness was more common in the conservative treatment group. Conclusion: According to our findings scapulothoracic joint angle changes were seen in the conservative treatment group more than in the surgery group. Consequently, winged scapula was seen more commonly in the conservative treatment group than in the surgery group (p=0.001). Level of Evidence III; Retrospective comparative study .

Os pacientes foram tratados conservadoramente (Grupo I) ou cirurgicamente (Grupo 2). Deformidades planas, ângulo escapulotorácico, encurtamento e força muscular isocinética foram medidos. O Índice de Dor e Incapacidade do Ombro (SPADI) e a Short Form-36 (SF36) foram avaliados. Resultados: Os ângulos da articulação escapulotorácica foram maiores no grupo de tratamento conservador do que no grupo de cirurgia (p=0,036). Consequentemente, a escápula alada foi vista mais comumente no grupo de tratamento conservador do que no grupo de cirurgia (p=0,001). O tratamento cirúrgico foi associado a escores físicos SF-36 significativamente melhores e escores SPADI de dor e incapacidade. No entanto, os dois grupos não diferiram em termos de força muscular isocinética. A deformidade no plano anteroposterior negativo (p<0,001) e a deformidade no plano axial negativo (p=0,004) foram mais frequentes no grupo de tratamento conservador. O encurtamento da clavícula foi mais comum no grupo de tratamento conservador. Conclusão: De acordo com nossos achados, as alterações do ângulo escapulotorácico foram mais observadas no grupo de tratamento conservador do que no grupo de cirurgia. Consequentemente, a escápula alada foi vista mais comumente no grupo de tratamento conservador do que no grupo de cirurgia (p=0,001). Nível de Evidência III; Estudo comparativo retrospectivo .

Application of corrective calcaneal osteotomy in treatment of malunited calcaneal fractures / 中华创伤骨科杂志

Malunion is a common complication following a calcaneal fracture which was not treated or treated inappropriately.It is a therapeutic target and a great challenge as well to relieve pain, correct deformity and restore the function of the affected foot in clinical treatment of calcaneal malunion. As a result of researches by scholars at home and abroad focusing on the biomechanical mechanisms underlying the symptoms caused by calcaneal malunion, a variety of corrective calcaneal osteotomy has been widely applied in clinical practice to specifically correct the calcaneal deformity and restore normal calcaneal morphology. This review expounds on the techniques, outcomes, indications and complications of corrective calcaneal osteotomies commonly used in clinic.

Close reduction and internal fixation assisted by a 3D printed guide plate for Sanders type Ⅱ calcaneal fracture / 中华创伤骨科杂志

Objective:To compare minimally invasive treatment with versus without a 3D printed guide plate for Sanders type Ⅱ calcaneal fractures.Methods:A retrospective analysis was done of the 74 patients with Sanders type Ⅱ displaced intra-articular calcaneal fracture who had been treated at Foot and Ankle Surgery Center, Beijing Tongren Hospital Affiliated to Capital Medical University from January 2018 to January 2020. They were divided into 2 groups according to whether a 3D printed guide plate was used or not. In the 3D printing group of 38 patients treated by minimally invasive surgery assisted by a 3D printed guide plate, there were 22 males and 16 females with an age of (41.5±3.5) years; in the control group of 36 patients treated by traditional minimally invasive surgery, there were 24 males and 12 females with an age of (40.3±7.2) years. The 2 groups were compared in terms of operation time, intraoperative fluoroscopy, American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analog scale (VAS), Short Form 36 (SF-36), B?hler angle, Gissane angle, calcaneal length, width and height and postoperative complications.Results:There was no significant difference in the preoperative demographic data between the 2 groups, indicating comparability between groups ( P>0.05). All patients were available for a follow-up of (12.6±3.6) months (from 6 to 24 months) after surgery. The operation time [(55.3±7.1) min] and intraoperative fluoroscopy [(8.1±2.6) times] in the 3D printing group were significantly less than those in the control group [(71.2±8.7) min and (21.2±8.7) times] ( P<0.01) while the AOFAS score in the former group (81.4±6.3) was significantly higher than that in the latter (77.9±6.2) ( P<0.01). There were no statistically significant differences between the 2 groups in VAS, SF-36, B?hler angle, Gissane angle, calcaneal length, calcaneal width or calcaneus height ( P>0.05). In the control group, 4 screws were found to be too long with possible impingement on the medial structures of the foot, and 3 screws to penetrate the subtalar joint; in the 3D printing group, there were no too long or off-target screws in the sustentaculum tali. Conclusion:The minimally invasive treatment of Sanders type Ⅱ calcaneal fractures assisted by a 3D printing guide plate can reduce operation time, intraoperative fluoroscopy and potential complications, improving the clinical efficacy.

Manejo cirúrgico de fratura cominutiva de mandíbula por ferimento de arma de fogo: relato de caso / Surgical management of comminuted jaw fracture by firearms injury: case report

Os ferimentos por arma de fogo (FAF) são um grande problema de saúde pública. Na face, a mandíbula é o local de maior incidência, sendo a região de corpo mandibular a mais atingida e as lesões aos tecidos moles frequentemente a ela associadas. Em alguns casos, tais ferimentos apresentam-se de difícil resolução, sobretudo, em casos de fraturas cominutivas e lesões de tecidos moles com alta complexidade. Isso torna o atendimento desses pacientes um desafio para cirurgiões buco-maxilo-faciais. Desta forma, o objetivo deste artigo é relatar um caso de FAF em terço inferior da face, com comprometimento de tecidos moles e mandíbula, pela equipe de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral do Estado - Bahia. Paciente de 28 anos de idade, sexo feminino, vítima de FAF em terço inferior da face, por disparo acidental de espingarda. Ao exame clínico, pode-se observar ferimento perfuro-contuso em região de mandíbula e fratura cominutiva de corpo e ângulo mandibular à direita. A paciente foi submetida à cirurgia para remoção de fragmentos ósseos/corpos estranhos, fixação dos cotos com placa de reconstrução 2.4mm e sutura dos planos, em mesmo tempo cirúrgico, reestabelecendo a função da mandíbula. Portanto, devido à fisiopatologia variável dos FAF na mandíbula, não se indica um único padrão de tratamento para as fraturas cominutivas. Além disso, é indispensável o emprego de protocolos de limpeza cirúrgica imediata e antibioticoterapia nos casos com alto grau de cominuição, bem como, sugere-se realizar o tratamento definitivo o mais breve possível(AU)

Firearm injuries (FIs) are a major public health problem. On the face, the mandible is the place with the highest incidence of this trauma, with the mandibular body region being the most affected and the lesions to the soft tissues frequently associated with it. In some cases, such injuries are difficult to resolve, especially in cases of comminuted fractures and soft tissue injuries with high complexity. This makes the care of these patients a challenge for oral and maxillofacial surgeons. Thus, the objective of this article is to report a case of care for a FAF victim in the lower third of the face, with soft tissue and mandible involvement, by the Maxillofacial Surgery and Traumatology team at the Hospital Geral do Estado - Bahia. 28-year-old female patient, victim of FAF in the lower third of the face, due to acidental shotgun firing. On clinical examination, a perforated-blunt wound can be seen in the mandible region and comminuted fracture of the body and angle of the mandible on the right. The patient underwent surgery to remove bone fragments / foreign bodies, fix the stumps with a 2.4 mm reconstruction plate and suture the planes, at the same surgical time, reestablishing the function of the mandible. Therefore, due to the variable pathophysiology of FAF in the mandible, a single treatment pattern is not indicated for comminuted fractures. In addition, it is essential to use immediate surgical cleaning protocols and antibiotic therapy in cases with a high degree of comminution, as well as, it is suggested to carry out the definitive treatment as soon as possible(AU)

Association between Bone Mineral Density and Fracture Characteristics in the 5th Metatarsal Bone Base Fracture in Elderly for Prediction of Osteoporotic Fracture.

BACKGROUND: This study aimed to analyze the correlation between bone mineral density (BMD) and the type of 5th metatarsal fracture, as well as to demonstrate whether there is a difference in radiological findings (heel alignment angle [HAA], heel moment arm [HMA], and metatarsus angle) between fracture types. METHODS: A total of 87 patients were enrolled in the study and allocated into 3 groups: the Zone 1 group (N=36), the Zone 2 group (N=33), and the Zone 3 group (N=18). The participants' demographic data, T-scores, existing fracture or osteoporosis medications, and radiologic parameters including HAA, HMA, and metatarsus adductus angle were analyzed and compared. RESULTS: There was a significant difference between the mean age of the participants, with the highest age in the Zone 1 group and the lowest in the Zone 3 group. Regarding the history of concurrent fracture or osteoporosis medications, there was no significant difference between the 3 groups. Similarly, no significant difference was observed between the 3 groups about the BMD values. In contrast, the HAA was statistically significant in all groups with a positive correlation of -8.9 in the Zone 1 group, a negative correlation of 3.55 in the Zone 2 group, and an inverse relationship of 6.1 in the Zone 3 group. The metatarsus adductus angle was significantly higher in the Zone 3 group than the Zone 1 and Zone 2 groups. CONCLUSIONS: The location of a 5th metatarsal bone fracture is not significantly associated with BMD. However, mechanical influences, such as hindfoot varus or forefoot adductus, have a significant correlation with fracture types.

A Basic Intervention to Improve Compliance With Thromboprophylaxis in Patients With Neck of Femur Fracture.

Background: Venous thromboembolism (VTE) is a significant complication following orthopedic intervention for neck of femur fracture. Our aim was to evaluate compliance with The National Institute for Health and Care Excellence guidance surrounding VTE prophylaxis before and after a brief intervention in an orthopedic department at a district general hospital. Methods: A 2-cycle quality improvement project was conducted. The primary outcome measure was whether adequate thromboprophylaxis was appropriately prescribed. For the intervention between the 2 cycles, posters were placed in key prescribing areas of all orthopedic wards. Results: In cycle 1, 63 (76.8%) patients were correctly prescribed enoxaparin, and 14 (17.1%) were prescribed other anticoagulants, leaving 5 patients (6.1%) who did not receive thromboprophylaxis for no apparent reason. In cycle 2, 56 (87.5%) patients were correctly prescribed enoxaparin, and the remaining patients were covered with alternative therapies. Conclusion: Small but basic interventions can lead to improvements in VTE prophylaxis prescribing. Future focus should be on implementing similar interventions across hospitals.

Treatment of completely displaced distal radial fractures with a straight plaster or manipulation under anaesthesia.

AIMS: The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of 'off-ended' fractures in children with at least two years of potential growth remaining. METHODS: A total of 34 boys and 22 girls aged 0 to ten years with a closed, completely displaced metaphyseal distal radial fracture presented between 1 November 2015 and 1 January 2020. After 2018, children aged ten or under were offered treatment in a straight plaster or manipulation under anaesthesia with Kirschner (K-)wire stabilization. Case notes and radiographs were reviewed to evaluate outcomes. In all, 16 underwent treatment in a straight cast and 40 had manipulation under anaesthesia, including 37 stabilized with K-wires. RESULTS: Of the children treated in a straight cast, all were discharged with good range of mo (ROM). Five children were discharged at six to 12 weeks with no functional limitations at six-month follow-up. A total of 11 children were discharged between 12 and 50 weeks with a normal ROM and radiological evidence of remodelling. One child had a subsequent diaphyseal fracture proximal to the original injury four years after the initial fracture. Re-displacement with angulation greater than 10° occurred for 17 children who had manipulation under anaesthesia. Four had a visible cosmetic deformity at discharge and nine had restriction of movement, with four requiring physiotherapy. One child developed over- granulation at the pin site and one wire became buried, resulting in a difficult retrieval in clinic. No children had pin site infections. CONCLUSION: Nonoperative management of completely displaced distal radial fractures in appropriately selected cases results in excellent outcomes without exposing the child to the risks of surgery. This study suggests that nonoperative management of these injuries is a viable and potentially underused strategy. Cite this article: Bone Joint J 2021;103-B(5):902-907.

Arthroscopic surgery plus one or more posterior small incisions for calcaneal fractures / 中华创伤骨科杂志

Objective To compare the effects of arthroscopic surgery plus one or more posterior small incisions and the sinus tarsi approach in the treatment of calcaneal fracture.Methods A retrospective analysis was conducted of the 85 patients with calcaneal fracture who had been treated from January 2017 to June 2017 at Department of Foot & Ankle Surgery,Guangzhou Orthopaedic Hospital.They were 43 men and 42 women,32 to 58 years of age (average,46.0 years).Arthroscopic surgery plus one or more posterior small incisions was performed in 40 of them while the sinus tarsi approach was used in the other 45 cases.The 2 groups were compared in terms of operation time,fracture healing time,incision complications and functions of the affected foot by the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scores.Results There were no significant differences in the preoperative general data between the 2 groups,showing they were comparable (P ＞ 0.05).The average follow-up period for all the patients was 8 months (from 6 to 12 months).For the arthroscopic surgery group and sinus tarsi approach group,the fracture healing time was 8.6 ± 2.4 weeks and 8.9 ± 1.8 weeks,and the AOFAS ankle-hindfoot scores were 82.5 ± 5.6 and 85.1 ± 4.0,respectively,showing no significant differences between them (P ＞ O.05).The operation time in the arthroscopic surgery group (43.6 ±5.4 min) was significantly less than in the sinus tarsi approach group (56.5 ±6.4 minutes),and the rate of complications in the former[2.5％ (1/40)] significantly lower than in the latter[15.6％ (7/45)] (P ＜0.05).Conclusion Arthroscopic surgery plus one or more posterior small incisions may be a fine treatment for calcaneal fractures because postoperative incision complications can be reduced.

Clinical significance of thromboelastography and D-dimer in the assessment of thrombosis after vertebral augmentation / 中华老年医学杂志

Objective To explore changes in coagulation function,assessed by thromboelastography (TEG) combined with D-dimer (D-D),in patients undergoing percutaneous vertebroplasty(PVP)or percutaneous kyphoplasty(PKP).Methods A total of 52 elderly patients with osteoporosis-associated vertebral compression fractures admitted into our hospital from May 2016 to November were enrolled in this study,including 13 men aged 64-91 years,with a mean age of(74.3 ± 10.5) years,and 39 women aged 60-89 years,with a mean age of(71.4 ± 7.3) years.Patients received vertebroplasty under local anesthesia,with 29 patients undergoing PVP and 23 cases taking PKP.Thromboelastography(TEG)and D-dimer(D-D)levels were measured at 1 h before,0.5 h,1 h and 3 h after bone cement injections,in order to analyze changes in patients' coagulation function.Results Compared with the coagulation parameters in patients 1 h before bone cement injections,the values of R,K,Angle,Ma,CI,EPL,LY30 and D-D had no significant difference in patients 0.5 h after bone cement injections (P ＞ 0.05);the values of R,Angle,CI,EPL and LY30 were significantly different(P ＜0.05),but the values of K,Ma and D-D had no significant difference(P ＞0.05)in patients 1 h after bone cement injections;the values of R,K,Angle,Ma,CI,LY30 and D-D had no significant difference(P＞0.05),but the value of EPL was significantly different in patients 3 h after bone cement injections(P ＜0.05).Conclusions The blood is in a transient hypercoagulable state during the time of 0.5 h to 3 h after PVP or PKP,which reaches the peak at the time of 1 h after operation,thereby increasing the risk of thrombosis.Therefore,some interventions such as anticoagulants could be carried out during the preoperative and postoperative period.Changes in coagulation function should be closely monitored after operation.Patients should start postoperative exercise early.

A preoperative risk scoring system for elderly patients with hip fracture / 中华创伤骨科杂志

Objective To verify the effectiveness of a self-designed preoperative risk scoring system for elderly patients with hip fracture.Methods A total of 286 elderly patients with hip fracture were included for this prospective study who had been admitted from February 1,2014 to February 1,2016 to Department of Trauma and Orthopedics,Peking University People's Hospital.They were divided into 5 groups according to their scores by our self-designed preoperative risk scoring system for elderly patients with hip fracture:0 to 10 points,11 to 20 points,21 to 30 points,31 to 40 points and above 41 points.Postoperative complications and deaths were recorded.The correlations between their preoperative scores and postoperative medical complications or death were analyzed to verify the effectiveness of the preoperative risk scoring system for elderly patients with hip fracture.Results The 286 patients scored 24.9 ± 11.0 (from 0 to 69) preoperatively.The femoral neck fractures scored 24.0±11.0 and femoral intertrochanteric fractures 26.3±10.8.The incidence of medical complications was 4.00％ (1/25) in the 0 to 10 points group,4.17％ (3/72) in the 11 to 20 points group,14.66％ (17/116) in the 21 to 30 points group,23.53％ (12/51) in the 31 to 40 points group and 50.00％ (11/22) in the above 41 pints group.Conclusion As the incidence of postoperative medical complications in elderly patients with hip fracture is positively correlated with the scores by our self-designed preoperative risk scoring system for elderly patients with hip fracture,the preoperative risk scoring system can provide an effective prediction of surgical risks.

Factors Influencing on Pressure Ulcer Incidence among Older Patients with Hip Fracture in a Hospital

PURPOSE: This study aimed to identify the incidence and risks for pressure ulcer among older patients with hip fracture. METHODS: The subject were 215 older patients suffering from hip fracture who were admitted for surgical operation from January 1, 2012 to April 30, 2016 in a university-affiliated hospital. The incidence of pressure ulcer was collected retrospectively through medical record review and the risk factors were analyzed using Cox's proportional hazard model. RESULTS: Out of the total, 32 patients (14.9%) developed pressure ulcer with the average occurrence period being 4.72 (±3.81) days. Stage II pressure ulcer was the most common at 72.0%. Risk factors included ambulation status before injury (p=.039), spinal anesthesia (p=.029), and stay at intensive care unit after operation (p=.009). CONCLUSION: Despite pressure ulcer prevention efforts, the incidence remained relatively high. Considering the identified risk factors, more efforts is needed for early detection and prevention of pressure ulcers in such patients.

Fracture Non-Union: A Review of Clinical Challenges and Future Research Needs

@#Non-union of bone following fracture is an orthopaedic condition with a high morbidity and clinical burden. Despite its estimated global prevalence of nine million annually, the limit of bone regeneration therapy still results in patients living with pain, a reduced quality of life and associated psychological, social and financial repercussions. This review provides an overview of the current epidemiological and aetiological data, and highlights where the clinical challenges in treating non-union lie. Current treatment strategies are discussed as well as promising future research foci. Development in biotechnologies to treat non-union provides exciting scope for more effective treatment for this debilitating condition.

Comparison of antero-posterior and anterior approaches for unstable thoracolumbar fractures / 中华创伤骨科杂志

Objective To compare the clinical efficacy of anteroposterior approach (APA) versus anterior approach (AA) for decompression,fusion and fixation for single-level unstable thoracolumbar vertebrae fractures concomitant with incomplete neurologic symptoms and injury to posterior ligament complex (PLC).Methods From February 2006 to June 2012,55 patients were treated for single-level unstable thoracolumbar vertebrae fractures.Of them,27 were treated by only anterior decompression and lateral screw-rod instrumentation and 28 by anterior decompression and fusion combined with open posterior pedicle fixation of one to two segments above and below the fracture position.The 2 groups were compared at postoperative 3 and 12 months in terms of visual analogue scale (VAS),overall score of short-form health survey (SF-36),Japanese Orthopaedics Association (JOA) score of lower back,Oswestry disability index (ODI),loss ratio of anterior margin of vertebral height,endplate angle of kyphotic deformity of superior-inferior adjacent vertebrae,wedge angle of fractured vertebra via radiographic measurement and canal compromise rate.The neurologic functional recovery was analyzed using the American Spine Injury Association (ASIA) evaluation system at postoperative 12 months.Results There were no significant differcnces in operative time,amount of blood loss or postoperative drainage between the 2 groups (P ＞ 0.05).At postoperative 3 months,the VAS and JOA scores in the APA group were significantly better than those in the AA group (P ＜ 0.05).At 12 months after surgery,the VAS,kyphotic angle of adjacent vertebra,wedge angle of fractured vertebra and the ASIA improvements in the APA group were significantly better than those in the AA group (P ＜ 0.05).There were no significant differences between the 2 groups in the other indexes at postoperative 3 or 12 months (P ＞ 0.05).All the comparative indexes were significantly improved than the preoperative values in all the patients in the 2 groups at both 3 and 12 months (P ＜ 0.05).Conclusions Compared with the merely anterior approach,the combined antero-posterior approach may have advantages of better immediate and persistent reduction,steadily rebuilding fractured alignment,continuously maintaining injured biomechanical stability,and obviously improving neurological function.As the antero-posterior approach allows for combination of posterior auxiliary reduction and fixation with anterior definitive support and decompression,it may lead to a safe and effective treatment of unstable single-level thoracolumbar fracture concomitant with incomplete neurologic and PLC impairments.
