Bio-absorbable Cardiovascular Implants: Status and Prognosis
JOM, 2020There are three major classes of cardiovascular implants that can benefit from biodegradable materials: coronary/peripheral stents, occluders for heart defects, and embolic devices. We review the progress made in these three device classes, and offer our own prognosis for where the technology needs to improve.

Evaluation of absorbable PLA nasal implants in an ovine model [PDF]
Laryngoscope Investigative Otolaryngology, 2018 ABSTRACTObjectiveTo examine biocompatibility and absorption profile of a poly (L‐lactide‐co‐D,L‐lactide) 70:30 nasal implant.MethodsIn an ovine model, 66 rod‐shaped absorbable implants were placed in 11 nasal dorsa. The sheep were sacrificed at 1.5 (N = 3), 6 (N = 3), 12 (N = 3), 18 (N = 1), and 24 months (N = 1).

Absorbable implants versus metal implants for the treatment of ankle fractures: A meta-analysis
Experimental and Therapeutic Medicine, 2013 This meta-analysis was performed to evaluate the efficiency and the safety of absorbable implants. Five major electronic databases (PubMed, Embase, Cochrane Library, SinoMed and Wanfang Data) were systematically searched for randomized controlled trials (RCTs) from their establishment to November 2012.

Redisplacement after ankle osteosynthesis with absorbable implants
Archives of Orthopaedic and Trauma Surgery, 1998A total of 1202 fractures of the ankle were treated with absorbable implants made of polyglycolide/polylactide copolymer or self-reinforced polyglycolide and/or self-reinforced polylactide between November 5, 1984, and January 12, 1994. A redisplacement after fixation was diagnosed in 30 patients (2.5%).

Absorbable implants in fracture management
Foot and Ankle Clinics, 2002The use of absorbable implants has been studied extensively in the clinic and the laboratory. The limitations of absorbable implants are now well-known and include a finite life span and strength profile, the possible development of an inflammatory response, and their limitation to use in fractures that do not require traditional compression techniques.

Changes in Acoustic Absorbance Pre– and Post–Cochlear Implantation
American Journal of Audiology, 2022Purpose: Until recently, there has been little investigation on the effects of cochlear implantation on the transmission of acoustic stimuli through the middle-ear system. Recent studies have shown that cochlear implantation decreases low-frequency acoustic absorbance, consistent with a stiffer middle-ear system postsurgery ...

Gelatin as an Absorbable Implant in Scleral Buckling Procedures
Archives of Ophthalmology, 1968An absorbable gelatin implant (Ophthalmic Gelfilm) was used in 100 scleral buckling operations, 76 trap-door, and 24 scleral pouch procedures. This film produced an adequate buckle in selected cases. Since it was absorbed over a two- to five-month period, it was not associated with erosion. Extrusion or exposure through the conjunctiva was not observed.

[Osteosynthesis using absorbable implants].
Magyar traumatologia, ortopedia, kezsebeszet, plasztikai sebeszet, 1994Authors report on one case of malleolar synthesis with the use of biodegradable implants. The advantages of the resorbing osteosynthesis materials and the possible complications are described.

Optimal Conditions for Absorbable Fixation of Hydroxyapatite Ceramic Implants
Journal of Craniofacial Surgery, 2018Abstract Synthetic hydroxyapatite (HAP) implants are common in craniofacial surgery; the major problem with HAP implants is fixation instability. An ultrasound-assisted pinned resorbable fixation system has recently been introduced. The authors hypothesized that this resorbable system could be used to fix HAP implants.

Absorbable implants for fracture fixation
2011♦ Use of absorbable fracture fixation devices eliminates hardware removal procedures♦ Of the macromolecular biodegradable compounds, suited for the manufacturing of these implants, polylactide is the most widely used♦ Small-fragment intra-articular fractures, especially at the elbow and at the ankle, are the most rewarding clinical applications ...
