“…Many of the patients considered for TTCA have multiple comorbidities affecting bony stability [6][7][8]27]. Intracalcaneal fixation has been shown to be an important factor affecting stability [18,20,27]. Mann et al concluded that the posterior-to-anterior routing of a calcaneal locking screw significantly enhances stability [18].…”

“…The first biomechanical studies in the literature investigated first-generation retrograde (femoral) nails without foot and ankle specific locking options [14][15][16][17]. Secondgeneration nails with foot and ankle specific locking options such as anteroposterior locking within the calcaneus and/or optional compression were designed to increase stability [18][19][20]. In 2010, another system with a triple-bend retrograde intramedullary nail (A3, Stryker, Airview Boulevard, MN, USA) was introduced [1].…”

“…Furthermore, the nails lost an additional 10% of compression after 10,000 cycles. In a cyclic biomechanical assessment of compressed and noncompressed angle-stable locking IM nails, the angle-stable nails with compression showed an increase in stability (decreased range of motion) throughout 100,000 cycles in synthetic bone [34].…”

Tibio-talo-calcaneal (TTC) arthrodesis is a procedure to treat severe ankle arthropathy by providing a pain-free and stable fusion. Intramedullary (IM) nails offer a method of internal fixation for TTC arthrodesis by providing compressive stability, as well as shear and torsional rigidity. IM nails have been developed to apply compression to the TTC complex during installation; however, current designs are highly susceptible to a loss of compression when exposed to small amounts of bone resorption and cyclic loading. Nickel titanium (NiTi) is a shape-memory alloy capable of recovering large amounts of deformation via shape-memory or pseudoelasticity. Currently, the next generation of IM nails is being developed to utilize the adaptive, pseudoelastic properties of NiTi and provide a fusion nail that is resistant to loss of compression or loosening. Specifically, the pseudoelastic IM nail contains an internal NiTi compression element that applies sustained compression during the course of fusion, analogous to external fixators.

“…3,12,[14][15][16] Progress of IMN design to incorporate angle-stable locking screws has also increased biomechanical advantages to earlier nail designs with only static screw design. 15,17 Our study suggests that the biomechanical laboratory results are translated in the clinical setting.…”

Tibiotalocalcaneal arthrodesis is a salvage procedure. We report on the operative technique, the importance of addressing concomitant ankle and foot deformities when present and the outcomes (radiologic fusion rate, limb salvage rate, and global patient satisfaction) with a hindfoot arthrodesis nail. It was used for tibiotalocalcaneal arthrodesis on 63 consecutive patients (6 bilateral procedures). The minimum follow-up was 12 months; the mean age was 59 (range, 24 to 87) years, with 69% male. At 3 months, the fusion rate was 77.7% (49/63); 6-month fusion rate was 95% (60/63). The overall complication rate was 12.6% (8/63). There was a 100% limb salvage rate. Fifty-seven concomitant procedures were performed on 38 patients at time of nail insertion.

Angle-Stable and Compressed Angle-Stable Locking for Tibiotalocalcaneal Arthrodesis with Retrograde Intramedullary Nails

Abstract: Regardless of the bone model, the nails with angle-stable or compressed angle-stable locking had better initial stability and better stability following cycling than did the nails with static locking.
