Incidence and Epidemiology of Patellar Fractures

Abstract

The literature lacks large-scale, up-to-date, population-based epidemiology studies on the incidence of patellar fractures based on complete populations. The purpose of this study was to provide up-to-date information concerning the incidence of patellar fractures in a large and complete population spanning a decade and to report on the distribution of fracture classification, trauma mechanisms, and patient baseline demographics. A retrospective review of clinical and radiological records of 756 patellar fractures treated between 2005 and 2014 was conducted. Mean age at the time of fracture was 54±21 years. Mean age was 46±22 years for males and 61±18 years for females. The sex distribution was 425 (56%) females and 331 (44%) males. The incidence of patellar fractures between 2005 and 2014 was 13.1/100,000/ year with a year-to-year variation between 10.5 and 16.5/100,000/year during the 10-year observation period. The distribution of incidence shows an increase with increasing age. Males have the highest incidence of fracture in the 10-to-19-year age group, approximately 15.4/100,000/year. Females in the 60-to-80-year age group have the highest incidence, approximately 36/100,000/year. AO type 34-C3 was the most common fracture type, representing 25% of all patellar fractures, followed by AO type 34-C1, representing 23%. [Orthopedics. 2016; 39(6):e1154-e1158.].

Quality of life of patients with various variants of osteosynthesis of patellar fractures.

“…ізе үсті сүйегі сынықтары травматологиялық тәжіри-беде өте жиі кездеспегенімен, аяқ зақымдалулары құрылымында айтарлықтай маңызға ие. Әр түрлі авторлардың мәліметтері бойынша оның жиілігі 1,0% ден 7,0% дейін кездеседі [1,2]. Тізе үсті сүйегіне ағзадағы ең күшті бұлшықет болып саналатын квадрицепс күші әсер ететіндіктен, оның сынуы кезінде мықты фиксация жасау мақсатында оперативті ем жасау қажеттілігі туады.…”

Modified two-tension-band for patellar fractures

“…Inclusion criteria were the following: (1) skeletally mature patients with a patellar fracture, defined as 3 mm of fragment diastasis with loss of knee extension or articular step of 2 mm or more; 10,11 (2) fixation technique using AO TBW or MTTB with or without accompanying K-wires; and (3) a minimum followup of at least 1 year. Exclusion criteria comprised: (1) open and vertical component of the fracture pattern; (2) use of alternative fixation devices (for example, screw fixation); and (3) patients with polytrauma or disease that may influence the affected knee. All of the surgical treatments were performed by the same surgeons.…”

A novel technique of using a miniature plate in combination with tension band wiring to treat comminuted patellar fractures

“…[1] Fracture of the patella is not common, accounting for only approximately 1% of all skeletal injuries. [2] One-third of patella fractures require surgical intervention if the fracture gap exceeds 2 to 3 mm or in patients with joint incongruence. [3] Tension wiring is the most widely used surgical intervention for almost all fracture types.…”
