Biomechanical Evaluation of Fractured Tibia Externally Fixed With an LCP

Chaosuan Kanchanomai and Vajara Phiphobmongkol

A locking compression plate (LCP) can serve as an external fixation for fractured tibia. However, there is concern about the stability and endurance during partial weight bearing. This study was experimentally evaluated the effects of fracture gap sizes (1, 5, and 10 mm) on the stability and endurance of fractured tibia externally fixed with a 316L-stainless LCP. For stable fractured tibia (1-mm fracture gap), the large contact area of fracture surfaces resulted in nearly similar stiffness to that of intact tibia. The partial weight bearing is therefore possible. Whereas smaller contact area and no contact of fracture surfaces were observed for tibias with 5-mm and 10-mm fracture gaps, respectively. Their stiffnesses were significantly lower than those of intact tibia and tibia with 1-mm fracture gap. Thus, the partial weight bearing should be considered carefully in early phase of treatment. All LCP-tibial models were cyclically loaded beyond 500,000 cycles, that is, approximately 6 months of healing, without any failure of LCP. Thus, the failure of LCP is unlikely a critical issue for the present cases.

Differences in Function and Fracture Risk in Postmenopausal Women With and Without a Recent Distal Radius Fracture

Katie Crockett, Saija A. Kontulainen, Jonathan P. Farthing, Philip D. Chilibeck, Brenna Bath, Adam D.G. Baxter-Jones, and Catherine M. Arnold

Distal radius fractures (DRF) are the most common fractures in women over the age of 50 years ( Edwards et al., 2006 ; Handol, Madhok, & Howe, 2006 ; Mulhall, Ahmed, Khan, & Masterson, 2002 ), with the incidence increasing from 9% at age 50–59 to 38% after age 80 ( Barrett-Conner, Weiss, McHorney

What Factors Contribute to Falls-Related Distal Radius Fracture?

Sheena S. Philip, Joy C. Macdermid, Saranya Nair, Dave Walton, and Ruby Grewal

Distal radius fracture (DRF) is a common, debilitating injury of the upper extremity with a crude incidence of 175.5/100,000 persons in the United States ( Orces & Martinez, 2010 ). The number of older adults (>50 years) who received treatment for forearm and hand fractures increased by 15.2% in U

Movement Patterns in Older Adults Recovering From Hip Fracture

Jules J.M. Kraaijkamp, Marjon Stijntjes, Jurriaan H. De Groot, Niels H. Chavannes, Wilco P. Achterberg, and Eléonore F. van Dam van Isselt

Hip fractures are an increasingly frequent consequence of falls in older adults and are becoming a significant concern. It is estimated that 30%–60% of older adults who suffer a hip fracture experience permanent limitation to mobility or to their general level of independence ( Dyer et al., 2016

Blow-Up Fracture With Concussion in a Division I Collegiate Female Soccer Player

Kelly M. Seevers, Hannah G. Stephenson, and Adam B. Rosen

Key Points ▸ Division I collegiate female soccer player diagnosed with blow-up fracture and concussion. ▸ Blow-up fractures are uncommon in sport. ▸ Treatment varies based on severity of fractures and compounding factors such as a concussion. Between the 2014/2015 and 2018/2019 reporting years, an

Performance Outcomes After Hook of Hamate Fractures in Major League Baseball Players

Michael S. Guss, John P. Begly, Austin J. Ramme, David P. Taormina, Michael E. Rettig, and John T. Capo

Major League Baseball (MLB) players are highly skilled athletes that require full function of their hands to perform at the highest level, and are at risk for hook of hamate fractures while swinging the bat, or from direct blunt trauma, such as a fall on an outstretched hand or an errant pitch. 1

Factors Associated With Skeletal Muscle Mass Increase by Rehabilitation in Older Adults With Vertebral Compression Fractures

Takahiro Ogawa, Yuki Sueyoshi, Shintaro Taketomi, and Nobumasa Chijiiwa

Age-related sarcopenia and osteoporosis-related fractures are critical health issues among older adults. In general, many older adults suffer from fractures and spend much time in bed rest, inducing decreased skeletal muscle mass and function deterioration, such as in activities of daily living

Sequential Vertical Shear Fractures of the Medial Malleolus in a High School Football Player: A Case Report and Literature Review

Sravya Vajapey and Timothy L. Miller

Key Points ▸ Vertical fractures of the medial malleolus are rare but inherently unstable fractures due to shear forces created during weightbearing. ▸ These injuries occur most commonly in the presence of a varus hindfoot deformity or as a stress fracture from repetitive overuse or anteromedial

Infrared Thermography—A Novel Tool for Monitoring Fracture Healing: A Critically Appraised Topic With Evidence-Based Recommendations for Clinical Practice

Tristan Castonguay and Geoff Dover

Clinical Scenario Stress fractures are among the most common overuse injuries in physically active individuals. 1 – 3 To diagnose stress fractures, physicians usually rely on diagnostic imaging examinations. 4 The problem with relying on diagnostic imaging is that the conventional radiography

In the appropriate clinical context, it can also lead to malunion of the fracture site and
