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.

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

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

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

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

Mallet finger injuries often occur during sports, and patients usually desire an early return to sporting activity. When surgical treatment is performed for previously untreated mallet finger fractures, it frequently results in proximal traction of bone fragments, and thus displacement, which makes

Despite the health benefits of sports participation, an increased prevalence of bone injuries in adolescents has raised concerns regarding the safety of intense athletic participation at a young age, since fractures can impair growth with potential lifelong effects ( 8 ).

fractures were first recognized in the literature in 1970. 1 At that time, navicular stress fractures were thought to be extremely rare, accounting for only 0.7–2.4% of all stress fractures. However, as awareness increased, so did the number of reported incidences of navicular stress fractures. 1 Still
