Chinese journal of traumatology = Zhonghua chuang shang za zhi. 2020;(2):78-83
Abstract
Trauma during pregnancy deserves special attention because of its management objectives, i.e. well-being of both pregnant woman and foetus. Maxillofacial trauma directly affects the nutrition of foetus by interfering with the normal functions in a pregnant woman such as mouth opening, mastication and breathing. Hence early restitution of form and function of maxillofacial skeleton is essential. However, the gravid status is associated with numerous anatomical and physiological changes which present with clinical dilemma related to imaging and treatment. A careful scrutiny of the patient's systemic and gestational status is absolutely essential before, during and after instituting any interventional procedures. We present a case of bilateral condyle fracture in a 30-year-old pregnant woman in the third trimester (32 weeks). She was treated with inter maxillary fixation using orthodontic brackets & elastics. After successful restitution of occlusion, the patient was advised aggressive physiotherapy which ensured normal mouth opening. Two weeks later, the patient delivered uneventfully. The patient was followed up at one month and 3 month and demonstrated restitution of normal occlusion, mouth opening and lower facial height. This article aims at analyzing the contemporary principles in management of maxillofacial trauma in a pregnant woman and clarifying the common misconceptions.

BMC musculoskeletal disorders. 2019;(1):449
Abstract
BACKGROUND Simultaneous bilateral femoral neck fracture is a very rare condition, even in osteoporotic elderly individuals. We report an atypical case of a young male adult who developed simultaneous bilateral femoral neck fractures without previous trauma or overuse. CASE PRESENTATION A 33-year-old man presented with discomfort in the bilateral groin, which had started 2 weeks previously. Bilateral femoral neck fractures were observed on a radiograph, and in addition, a fracture line was seen at the right subchondral region of the acetabulum using magnetic resonance imaging (MRI). Although the patient had no obvious risk factors associated with bone fragility, his bone mineral density measured using dual X-ray absorptiometry indicated severe osteoporosis (lumber spine: T score - 3.4 standard deviation [SD]; femoral neck: T score - 2.8 SD). Serum 25-hydroxyvitamin D level was deficient (19 ng/mL), which was considered to be partly due to non-sunlight exposure for 3 years owing to social withdrawal. Bilateral osteosynthesis was performed, considering his young age, although more than 2 weeks had passed since the onset of the fracture. Bone union and non-occurrence of osteonecrosis of the femoral head were confirmed via radiography and MRI 8 months after the surgery. CONCLUSIONS Our case suggests that simultaneous non-traumatic bilateral femoral neck fractures can occur in healthy young men.

Optimizing the Host in Fracture Surgery.
Bergin, PF, Tarkin, IS, Kempton, LB, Sagi, HC, Hsu, J, Archdeacon, MT
Journal of orthopaedic trauma. 2019;:S34-S38
Abstract
Multiple factors impact fracture healing; thus, endocrine optimization and nutritional optimization warrant investigation in the acute fracture and nonunion patient. This article presents current evidence regarding the role of the endocrinologists and the dietician in the fracture patient as well as the most recent data assessing the vitamin D axis in these populations. Similarly, the most recent information regarding the use and risks of NSAIDs in fracture healing are presented. The fracture surgeon must consider each individual patient and weigh the benefits versus the costs of host optimization.

Abstract
PURPOSE The need for spinal instrumented fusion in osteoporotic patients is rising. In this review, we try to give an overview of the current spectrum of pedicle screw augmentation techniques, safety aspects and indications. METHODS Review of literature and discussion of indications, limitations and technical aspects. RESULTS Various studies have shown higher failure rates in osteoporotic patients, most probably due to reduced bone quality and a poor bone-screw interface. Augmentation of pedicle screws with bone cement, such as polymethylmethacrylate or calcium based cements, is one valid option to enhance fixation if required. CONCLUSIONS Crucial factors for success in the use of augmented screws are careful patient selection, a proper technique and choice of the ideal cement augmentation option.

Abstract
AIMS: Treatment guidelines for atypical femoral fractures associated with bisphosphonates have not been established. We conducted a systematic review of the treatment of atypical femoral fractures first, to evaluate the outcomes of surgical fixation of complete atypical fractures and secondly, to assess whether prophylactic surgery is necessary for incomplete atypical fractures. MATERIALS AND METHODS Case reports and series were identified from the PubMed database and were included if they described the treatment of atypical femoral fractures. In total, 77 publications met our inclusion criteria and 733 patients with 834 atypical complete or incomplete femoral fractures were identified. RESULTS For complete fractures, internal fixation was predominantly achieved by intramedullary nailing. The mean time to healing post-operatively was 7.3 months (2 to 31). Revision surgery for nonunion or implant failure was needed in 77 fractures (12.6%). A greater percentage of fractures treated with plate fixation (31.3%) required revision surgery than those treated with intramedullary nailing (12.9%) (p < 0.01). Non-operative treatment of incomplete fractures failed and surgery was eventually needed in nearly half of the patients (47%), whereas prophylactic surgery was successful and achieved a 97% rate of healing. CONCLUSION Intramedullary nailing is the first-line treatment for a complete fracture, although the risk of delayed healing and revision surgery seems to be higher than with a typical femoral fracture. Non-operative treatment does not appear to be a reliable way of treating an incomplete fracture: prophylactic intramedullary nailing should be considered if the patient is in intractable pain. Radiographs of the opposite side should be obtained routinely looking for an asymptomatic fracture. Bisphosphonates must be discontinued but ongoing metabolic management in the form of calcium and/or vitamin D supplements is advisable. Teriparatide therapy can be considered as an alternative treatment. Cite this article: Bone Joint J 2017;99-B:295-302.

Optimal Positioning for Volar Plate Fixation of a Distal Radius Fracture: Determining the Distal Dorsal Cortical Distance.
Vosbikian, MM, Ketonis, C, Huang, R, Ilyas, AM
The Orthopedic clinics of North America. 2016;(1):235-44
Abstract
Distal radius fractures are currently among the most common fractures of the musculoskeletal system. With a population that is living longer, being more active, and the increasing incidence of osteoporosis, these injuries will continue to become increasingly prevalent. When operative fixation is indicated, the volar locking plate has recently become the treatment of choice. However, despite its success, suboptimal position of the volar locking plate can still result in radiographic loss of reduction. The distal dorsal cortical distance is being introduced as an intraoperative radiographic tool to help optimize plate position and minimize late loss of fracture reduction.

Optimizing Stability in Femoral Neck Fracture Fixation.
Ye, Y, Hao, J, Mauffrey, C, Hammerberg, EM, Stahel, PF, Hak, DJ
Orthopedics. 2015;(10):625-30
Abstract
Optimizing stability of femoral neck fracture fixation is important in obtaining a successful outcome. The mechanical problems and strategies for achieving optimal stability differ depending on patients' age and degree of osteoporosis. Femoral neck fractures in younger adults usually result from high-energy trauma and have a vertical fracture pattern. Strategies for optimizing fixation stability in this group include placing additional screws at right angles to the fracture plane and medial buttress plate augmentation. In elderly patients, screw position relative to the intact cortical femoral neck bone is of critical importance. Additional strategies for optimizing fixation stability in this group include the concept of length stable fixation, use of adjunctive calcium phosphate cement, and use of novel fixed angle fixation implants.

Delayed union and nonunions: epidemiology, clinical issues, and financial aspects.
Hak, DJ, Fitzpatrick, D, Bishop, JA, Marsh, JL, Tilp, S, Schnettler, R, Simpson, H, Alt, V
Injury. 2014;:S3-7
Abstract
Fracture healing is a critically important clinical event for fracture patients and for clinicians who take care of them. The clinical evaluation of fracture healing is based on both radiographic findings and clinical findings. Risk factors for delayed union and nonunion include patient dependent factors such as advanced age, medical comorbidities, smoking, non-steroidal anti-inflammatory use, various genetic disorders, metabolic disease and nutritional deficiency. Patient independent factors include fracture pattern, location, and displacement, severity of soft tissue injury, degree of bone loss, quality of surgical treatment and presence of infection. Established nonunions can be characterised in terms of biologic capacity, deformity, presence or absence of infection, and host status. Hypertrophic, oligotrophic and atrophic radiographic appearances allow the clinician to make inferences about the degree of fracture stability and the biologic viability of the fracture fragments while developing a treatment plan. Non-unions are difficult to treat and have a high financial impact. Indirect costs, such as productivity losses, are the key driver for the overall costs in fracture and non-union patients. Therefore, all strategies that help to reduce healing time with faster resumption of work and activities not only improve medical outcome for the patient, they also help reduce the financial burden in fracture and non-union patients.

[Fractures of the knee joint in the elderly: osteosynthesis versus joint replacement].
Pape, D, Hoffmann, A, Gerich, T, Van der Kerkhofe, M, Weber, M, Pape, HC
Der Orthopade. 2014;(4):365-73
Abstract
BACKGROUND The aim of open reduction and internal fixation (ORIF) of fractures around the knee joint is the exact anatomic reconstruction of joint surfaces in order to achieve an early and load stable bone situation. Primary endoprosthetics as the initial treatment can represent an alternative treatment option for a closely selected number of geriatric patients. OBJECTIVES The chances and risks of primary endoprosthetics in comparison to ORIF as the gold standard for initial treatment of fractures close to the knee joint in the elderly are presented MATERIAL AND METHODS A selective search of the literature was carried out in consideration of national recommendations and own experience gained as head of a center for geriatric traumatology. RESULTS If the soft tissue coverage is not damaged by the injury, primary endoprosthetics can offer advantages compared to ORIF when a load stable joint is indispensable due to poor compliance, pre-existing arthritis and advanced age. DISCUSSION The risk of postoperative loss of correction is minimized by the prosthesis but the revision possibilities are very limited due to voluminous prostheses with a high degree of coupling. The indications for primary prosthesis implantation for acute treatment of fractures close to the knee should therefore be closely controlled because this should be the first and last intervention for fracture treatment in geriatric patients.

Absorbable and non-absorbable cement augmentation in fixation of intertrochanteric femur fractures: systematic review of the literature.
Namdari, S, Rabinovich, R, Scolaro, J, Baldwin, K, Bhandari, M, Mehta, S
Archives of orthopaedic and trauma surgery. 2013;(4):487-94
Abstract
We conducted a systematic review of the literature on the use of both resorbable and non-resorbable cement as an adjunct to internal fixation of intertrochanteric hip fractures. Two reviewers independently assessed the methodological quality and extracted relevant data from each included study. In cases in which the outcomes data were similar between studies, data were pooled and analyzed. Seven studies were included after fulfilling all inclusion and exclusion criteria. Two hundred and eighty patients were treated with augmentation and 175 were treated without augmentation. Studies were variable in their ability to demonstrate better functional outcomes in patients who underwent augmentation. However, radiographic parameters (mean lag screw sliding distance and varus deformity) were better in the augmentation group. In terms of complications, failure to use augmentation with a sliding hip screw device in five studies led to 10.8-fold higher likelihood of construct failure (p < 0.01). Augmentation of intertrochanteric femur fractures with polymethyl methacrylate or calcium-phosphate may provide benefits in terms of radiographic parameters and complication rates; however, more stringent research methodology is necessary to determine the extent of the benefit.
