Incidence and predictors of valgus tibiotalar tilt after progressive collapsing foot deformity reconstruction using subtalar fusion with concomitant procedures

Impact of Subtalar Distraction Arthrodesis on Ankle Joint: Radiological Insights from Modified Grice–Green Procedure

“…In contrast to findings reported by previous authors [ 13 , 14 ], the modified Grice–Green SDA did not appear to correlate with the occurrence of valgus talar tilt.…”

“…SDA stands as a widely employed surgical intervention, renowned for its remarkable efficacy in reinstating optimal talo-calcaneal alignment. Recent scrutiny by select researchers has unveiled the possibility of subtalar intervention exerting consequential effects on the articulatory dynamics at the tibiotalar interface [ 13 , 14 ]. Given the array of surgical methodologies available for executing subtalar fusion, the primary objective of this study was to evaluate whether the modified Grice–Green SDA engendered alterations in the tibiotalar relationships.…”

“…Additionally, a minimum follow-up period of 8 months was selectively adopted for patient inclusion. This choice was informed by previous investigations, which revealed the emergence of postoperative valgus tibiotalar tilt at mean follow-up intervals of 3.6 months per Miniaci-Coxhead et al and 7.7 months per Kim et al [ 13 , 14 ]. In a bid to achieve meticulousness, a conservative threshold of 8 months was established to ensure comprehensive assessment and to navigate potential fluctuations in postoperative outcomes.…”

“…In the research conducted by Kim et al involving a cohort comprising 59 patients, the findings revealed that 28.8% of the subjects exhibited the development of postoperative valgus talar tilt. Moreover, the study elucidated a statistically significant association between a heightened degree of hindfoot valgus and the incidence of valgus talar tilt following the surgical intervention [ 13 ]. A similar percentage was also observed by Miniaci-Coxhead et al In their study involving 187 patients, 27.3% developed a postoperative valgus tibiotalar tilt.…”

“…This is despite Fitzgibbons’ observation in 1996 that hindfoot fusion appeared in some cases to be associated with the development of tibiotalar valgus tilt [ 12 ]. Since then, only two studies have addressed this issue, providing limited insights into its complexities and implications [ 13 , 14 ].…”
