“…This has been previously attempted in the case of the incus. 2,14 These authors used a wire passing around the incus and through the stapes arch. No attempt was made to mobilize the body of the incus.…”

“…6,7,13 Surgical correction of incus dislocation can be carried out using conventional ossiculoplasty techniques, bone graft repair or repositioning of the incus. 2,6,7,14,15 Fractures of the stapes arch can be managed by the use of a strut or piston between the incus and stapes, 6,9 while stapes luxation can be treated by stapedectomy 10 or restoration of the ossicle to its former position, secured with tissue adhesive. 16 Small bone grafts can also be used to treat malleus handle fractures.…”

Data have been collected prospectively from 11 patients (12 affected ears) with traumatic disruption of the ossicular chain. Isolated dislocation of the incus is the most common finding in our cases, but two had stapes arch features and two had fractures of the tympanic bone. The most common cause of the injuries was a road traffic accident. We describe a technique designed to reposition the incus in its physiological position. This involves a combination of a tympanotomy and a posterior approach to the attic region. The results in five patients (six ears) treated in this way are presented.

“…IS joint abnormalities, such as disarticulation and ankylosis, can induce severe conductive hearing loss or even deafness (Holler and Greenberg 1972; Suzuki et al 2008; Sim and Chang 2008). The design and evaluation of middle ear surgery and reconstruction of the middle ear with ossicular prosthesis are also related to the structure and mechanical properties of the IS joint (Schwetschenau and Isaacson 1999; Vishwakarma et al 2009; Celik et al 2009).…”

The incudostapedial (IS) joint between the incus and stapes is a synovial joint consisting of joint capsule, cartilage, and synovial fluid. The mechanical properties of the IS joint directly affect the middle ear transfer function for sound transmission. However, due to the complexity and small size of the joint, the mechanical properties of the IS joint have not been reported in the literature. In this paper, we report our current study on mechanical properties of human IS joint using both experimental measurement and finite element (FE) modeling analysis. Eight IS joint samples with the incus and stapes attached were harvested from human cadaver temporal bones. Tension, compression, stress relaxation and failure tests were performed on those samples in a micro-material testing system. An analytical approach with the hyperelastic Ogden model and a 3D FE model of the IS joint including the cartilage, joint capsule, and synovial fluid were employed to derive mechanical parameters of the IS joint. The comparison of measurements and modeling results reveals the relationship between the mechanical properties and structure of the IS joint.
