Fixation with Bioabsorbable Pins in Chevron Bunionectomy*

Fixation of Mitchell’s osteotomy with bioabsorbable pins for treatment of hallux valgus deformity

“…In the case of bioabsorbable polymers, such reactions manifest as granulomas, sterile sinus formation, osteolysis and pronounced fibrous encapsulation [8,11]. Several predisposing factors including implant-related, site-related and patient-related causes are known [10]. Poly(p-dioxanone) is a relatively fast absorbing homopolymer, but its incidence of foreign body reaction is low.…”

“…Poly(p-dioxanone) is a relatively fast absorbing homopolymer, but its incidence of foreign body reaction is low. In the literature all reports of the use of poly(p-dioxanone) in the correction of hallux valgus deformity are related to chevron osteotomy [10,14,22,25]. In these series the reported incidence of osteolytic reactions ranges from 0 to 9%.…”

Bioabsorbable Implants

“…Numerous series have been published having no reportable reactions [10][11][12][13]. Gill and colleagues [14] in 1997 was the first to report osteolysis associated with Orthosorb pins. Conversely, this series saw similar numbers and types of reaction with k-wire fixation.…”

“…Numerous articles have compared Orthosorb pins to k-wire fixation [10][11][12]14]. Several additional articles looked at using PLLA or copolymer pins [20,37].…”

Influence of anionic monomer content on the biodegradation and toxicity of polyvinyl-urethane carbonate-ceramic interpenetrating phase composites

“…Degradable polymeric systems, such as polyglycolide (PGA) [3,4], polylactide (PLA) [5,6] and polydioxanone (PDS) [7] as well as various copolymers of PGA and PLA [8,9] have been investigated for their potential use in the fixation of damaged bone due to trauma or orthopaedic disease, but their success has been limited to low load bearing skeletal sites due to their poor initial stiffness and strength. Self-reinforced polylactides (SR-PLLA) which contain oriented fibers of the same chemical composition, represent the currently used materials in the fabrication of biodegradable implants for fracture repair.…”
