Calcar-collar contact during simulated periprosthetic femoral fractures increases resistance to fracture and depends on the initial separation on implantation: A composite femur in vitro study.

Clin Biomech (Bristol, Avon) 2021 Jun 10;87:105411. Epub 2021 Jun 10.

School of Mechanical Engineering, University of Leeds, Leeds LS2 9DX, UK.

Background: A calcar collar may reduce risk of periprosthetic fracture of the femur, through collar contact. We estimated the effect of collar contact on periprosthetic fracture mechanics using a collared fully coated cementless femoral stem and then estimated the effect of initial calcar-collar separation on the likelihood of collar contact.

Methods: Three groups of six composite left femurs with increasing calcar-collar separation in each group, underwent periprosthetic fracture simulation in a materials testing machine. Read More

Twelve-Month Outcomes of the AFFINITY Trial of Fluoxetine for Functional Recovery After Acute Stroke: AFFINITY Trial Steering Committee on Behalf of the AFFINITY Trial Collaboration.

Stroke 2021 May 21:STROKEAHA120033070. Epub 2021 May 21.

Canadian Blood Services and University of Toronto, Ontario, Canada (Q.Y.).

Background And Purpose: The AFFINITY trial (Assessment of Fluoxetine in Stroke Recovery) reported that oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and seizures. After trial medication was ceased at 6 months, survivors were followed to 12 months post-randomization. This preplanned secondary analysis aimed to determine any sustained or delayed effects of fluoxetine at 12 months post-randomization. Read More

Brachial plexopathy as a consequence of nerve root swelling after shoulder trauma in a patient following an acute seizure.

Turk J Pediatr 2021 ;63(1):161-166

School of Medicine, Universidade Sao Francisco, Braganca Paulista, Brasil.

Background: Epileptic seizures might be associated with an increased risk of fractures, either as a result of trauma after a fall or as a result of excessive muscle contraction. In the pediatric population, excessive muscle contraction is a more significant risk factor for fractures, due to the lack of maturity in the musculoskeletal system, while antiepileptic therapy itself can lead to a reduction of bone density. Proximal humeral fractures in the pediatric population are not frequent but both proximal humeral fractures and shoulder dislocation increase the chance of brachial plexus injuries and peripheral nerve lesions.

Use of the Humeral Head as a Reference Point to Prevent Axillary Nerve Damage during Proximal Fixation of Humeral Fractures: An Anatomical and Radiographic Study.

Strategies Trauma Limb Reconstr 2020 May-Aug;15(2):63-68

Department of Neuroscience, Erasmus MC Anatomy and Research Program, Rotterdam, The Netherlands.

Introduction: Treatment of proximal humeral fractures with plate osteosynthesis or intramedullary nail fixation in humeral shaft fractures with a proximal locking bolt carries the risk of iatrogenic injury of the axillary nerve. The purpose of this anatomical study is to define a more reliable safe zone to prevent iatrogenic axillary nerve injury using the humeral head instead of the acromion as a (radiographic) reference point during operative treatment.

Materials And Methods: Anatomical dissection and labeling of the axillary nerve and branches was performed on 10 specially embalmed human specimens. Read More

Radiography (Lond) 2021 Jan 22. Epub 2021 Jan 22.

Gujarat Cancer Research Institute (GCRI), Ahmedabad, Gujarat, India. Electronic address:

Introduction: We propose a ''A to Z RAM (Radiograph Assessment Method)'' for evaluation of Radiograph of patients with a suspected bone tumour.

Methods: In the current study, ten radiological features with letters 'A, B, C, D, E, F and Z' were used and which included the age of the patient, involved part of the bone, characteristics, content, distinctiveness, the exterior of the bone, fracture, and zone of transition.

Clinical Criteria for Selective Exploration of Orbital Floor in Zygomaticomaxillary Complex Fractures.

Craniomaxillofac Trauma Reconstr 2020 Sep 1;13(3):180-185. Epub 2020 May 1.

Department of Public Health Dentistry, SDM College of Dental Sciences and Hospital, Shri Dharmasthala Manjunatheshwara University, Dharwad, Karnataka, India.

Purpose: Exposing the orbital floor requires a surgical procedure that has its own challenges. Despite the meticulous clinical examination followed by sophisticated imaging modalities, orbital floor defects associated with zygomaticomaxillary complex (ZMC) fractures may evade diagnosis and appropriate management. If surgeons can decide about the need for orbital floor exploration in patients with ZMC fracture, the chance of a postoperative eyelid deformity can be prevented. Read More

The IlluminOss® photodynamic bone stabilization system for pathological osteolyses and fractures of the humerus: indications, advantages and limits in a series of 12 patients at 24 months of minimum follow-up.

BMC Musculoskelet Disord 2021 Jan 11;22(1):63. Epub 2021 Jan 11.

Oncological Orthopaedics Department, IRCCS - Regina Elena National Cancer Institute, Via Elio Chianesi 53, 00144, Rome, Italy.

Background: Locked titanium nails are considered the reference treatment for metastatic bone lesions of the humerus in patients with aggressive histotypes, high risk of fracture or when estimated survival is lower than 6 months.Nevertheless, they are responsible for CT and MRI artifacts which interfere with postoperative radiotherapy and follow-up.The IlluminOss® is an intramedullary stabilization system which is introduced inside the humeral canal in a deflated state, and is then distended with a monomer which hardens after exposure to blue light,stabilizing the segment; it does not cause artifacts, allowing easier and more effective radiotherapy and follow-up.

New possibilities: the LockDown device for distal clavicle fractures.

JSES Int 2020 Dec 15;4(4):713-718. Epub 2020 Oct 15.

Department of Trauma Surgery, Zaandam Medical Center, Zaandam, The Netherlands.

Background And Hypothesis: The majority of distal clavicle fractures are displaced fractures and constitute a treatment challenge because they have a 30% chance of delayed union or nonunion. Although several options for surgical reconstruction have been described, in patients with a comminuted and/or small distal fragment, these reconstructive options have proved to be prone to failure. Moreover, secondary surgery for removal is necessary in most cases. Read More
