“…Although measurements of the medial distal tibial angle, tibiotalar surface angle, and talar tilting angle are well-accepted methods for assessment of ankle alignment in the coronal plane, the radiographic assessment of hindfoot alignment remains controversial. The angle between the tibial shaft axis and the calcaneal axis was measured by Cobey [5] and Buck et al [4] using the hindfoot alignment view, and by Reilingh et al [24] using long axial view radiographs. However, it is not easy to define specific landmarks of the calcaneus for appropriate definition of the calcaneal axis owing to its irregular shape [26].…”

Background Patients with ankle arthritis often present with concomitant hindfoot deformity, which may involve the tibiotalar and subtalar joints. However, the possible compensatory mechanisms of these two mechanically linked joints are not well known. Questions/purposes In this study we sought to (1) compare ankle and hindfoot alignment of our study cohort with end-stage ankle arthritis with that of a control group; (2) explore the frequency of compensated malalignment between the tibiotalar and subtalar joints in our study cohort; and (3) assess the intraobserver and interobserver reliability of classification methods of hindfoot alignment used in this study. Methods Between March 2006 and September 2013, we performed 419 ankle arthrodesis and ankle replacements (380 patients). In this study, we evaluated radiographs for 233 (56%) ankles (226 patients) which met the following inclusion criteria: (1) no prior subtalar arthrodesis; (2) no previously failed total ankle replacement or ankle arthrodesis; (3) with complete conventional radiographs (all three ankle views were required: mortise, lateral, and hindfoot alignment view). Ankle and hindfoot alignment was assessed by measurement of the medial distal tibial angle, tibial talar surface angle, talar tilting angle, tibiocalcaneal axis angle, and moment arm of calcaneus. The obtained values were compared with those observed in the control group of 60 ankles from 60 people. Only those without obvious degenerative changes of the tibiotalar and subtalar joints and without previous surgeries of the ankle or hindfoot were included in the control group. Demographic data for the patients with arthritis and the control group were comparable (sex, p = 0.321; age, p = 0.087). The frequency of compensated malalignment between the tibiotalar and subtalar joints, defined as tibiocalcaneal angle or moment arm of the calcaneus being greater or smaller than the same 95% CI statistical cutoffs from the control group, was tallied. All ankle radiographs were independently measured by two observers to determine the interobserver reliability.

“…To evaluate the amount of axial deviation, a hindfoot alignment view [10] of the lower leg was obtained and the hindfoot axis with respect to the tibia measured according to Saltzman and el-Khoury [40]. The degree of arthritis at the ankle, subtalar, and talonavicular joints was documented by one of us (TE) using the radiographic scale provided by Bargon and Henkemeyer [3] (Table 1).…”

“…The functional results were evaluated by one of the authors (TE) with the AOFAS ankle/hindfoot scale [29]. Anteroposterior and lateral weight-bearing radiographs of the ankle and a hindfoot alignment view of the lower leg [10] were obtained to evaluate bone healing, the amount of arthritis in the adjacent joints as graded on the Bargon scale [3], and tibiotalar alignment. We measured sagittal motion at the midtarsal joint with lateral radiographs with the foot in dorsiflexion and plantarflexion (Fig.…”

When evaluating the role of ankle arthrodesis in the treatment of severe ankle arthritis, postoperative infection, nonunion, and the development of arthritis at the adjacent joints are major issues when considering treatment alternatives. We evaluated the rate of complications, the functional outcome, and compensatory range of motion at the midtarsal joint at medium-term followup after ankle arthrodesis with four cancellous screws. We performed 94 ankle fusions in 92 patients; 12 patients were lost to followup and eight declined to participate, leaving 72 patients (76%) for evaluation. The minimum followup was 4.8 years (mean, 5.9; range, 4.8-7.8 years). No patient developed a deep infection; three patients developed postoperative hematoma which we operatively drained. Union occurred in 93 of the 94 patients (99%). The sagittal motion at the midtarsal joint averaged 24°. Secondary arthritis of the subtalar and talonavicular joints developed during the followup period in 17% and 11%, respectively.

“…There are different methods how to quantify inframalleolar alignment (Fig. 5) including distance and angle between the longitudinal tibial axis and the lowest point of tuber calcanei [57], angle between the longitudinal tibial axis and calcaneal axis [62], and angles between the longitudinal tibial axis and osseous contours of calcaneus [63].…”

A variety of surgical procedures are utilized for management of ankle osteoarthritis. The most common etiology in patients with ankle osteoarthritis is post-traumatic often resulting in asymmetric ankle osteoarthritis with concomitant valgus or varus deformity. A substantial part of tibiotalar joint is often preserved, therefore, in appropriate patients, jointpreserving surgery holds the potential to be a superior treatment option than joint-sacrificing procedures including total ankle replacement or ankle arthrodesis. This review is designed to describe indications and contraindications for single-stage supramalleolar realignment surgery. Complications associated with this type of surgery and postoperative outcome are highlighted using recent literature.
