Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and severe deformity. The prevalence of postoperative complications remains high due to the complexity of hindfoot disease seen in these patients. The aim of this study was to analyze the relationship between preoperative conditions and postoperative complications in order to predict the outcome following primary TTC fusion. We retrospectively reviewed the medical records of 101 patients who underwent TTC fusion at the same institution between 2011 and 2019. Risk ratios (RRs) associated with age, sex, diabetes, cardiovascular disease, smoking, preoperative ankle deformity, and the use of bone graft during surgery were related to the postoperative complications. We determined from these data which pre- and perioperative factors significantly affected the outcome.Aims
Methods
Lengthening of the conjoined tendon of the gastrocnemius
aponeurosis and soleus fascia is frequently used in the treatment
of equinus deformities in children and adults. The Vulpius procedure
as described in most orthopaedic texts is a division of the conjoined
tendon in the shape of an inverted V. However, transverse division
was also described by Vulpius and Stoffel, and has been reported
in some clinical studies. We studied the anatomy and biomechanics of transverse division
of the conjoined tendon in 12 human cadavers (24 legs). Transverse
division of the conjoined tendon resulted in predictable, controlled
lengthening of the gastrocsoleus muscle-tendon unit. The lengthening
achieved was dependent both on the level of the cut in the conjoined
tendon and division of the midline raphé. Division at a proximal
level resulted in a mean lengthening of 15.2 mm ( Cite this article:
