Nineteen patients with 28 feet with congenital vertical talus were reviewed. The male to female ratio was equal, and associated congenital abnormalities were found in 15 of the 19 patients. No genetic pattern was established. Fifteen of the 16 surgically corrected feet were reevaluated, with an average follow-up of 60 months. Ten of the 15 feet were found to be in the good to excellent category, and five were rated poor. Twelve of 12 feet treated by cast correction were poor. Poor prognostic signs include late age of surgical correction, associated arthrogryposis and cerebral palsy, and an increased space between the calcaneus and cuboid. Best results occurred in those patients who had early surgical correction, after 4 to 6 months of serial casting, using magnification. Surgical technique which yielded the best results involved total release of the talus from the posterior, medial, and lateral approach, with reduction of the talocalcaneal as well as the talonavicular joints with multiple pin fixation. Lengthening of the Achilles tendon, extensor tendons, and peroneal tendons and transfer of the anterior tibialis to the navicular are recommended. Navicular excision was not found to be necessary. Surgical results in those patients over 3 1/2 years of age were found to be poor, and these individuals were considered for salvage procedures using a subtalar extra articular arthrodesis, excision of the navicular, or triple arthrodesis, depending on age.
Interruption of laryngeal innervation may partially or totally impair respiration, deglutition and phonation--the three basic laryngeal functions. Tucker has developed a principle of muscle-nerve pedicle transfer for laryngeal reinnervation to relieve airway obstruction following bilateral recurrent laryngeal nerve injury. We have applied the principle of reinnervation proposed by Tucker to treat patients not only with airway obstruction, but also with aspiration and impaired phonation due to interruption of laryngeal innervation. There were 23 patients in this study. The functional defects included: voice alteration in 10 patients, airway obstruction in 8 and aspiration, as well as a voice change, in 5. The causes of injury were surgery in 9 patients, trauma in 5, tumor in 3, polio in 1 and a birth defect in 1 patient. No cause of nerve injury could be determined in 4 patients. The technique employed involved selective reinnervation of the laryngeal nerve branches to one or more laryngeal muscle groups; the muscle groups reinnervated were selected so as to overcome the functional defect of each particular patient. The patients have been followed for 6 mo. or longer. The results have been independently evaluated by a speech pathologist and documented by indirect and direct endoscopic observations, as well as by audio and audio-video recordings. In some cases, there was further documentation by cine-fluoro-audio tape recordings, laryngo-pharyngography, laryngeal tomography and pulmonary function studies. The muscle-pedicle transfer technique described by Tucker was found to be useful to correct laryngeal dysfunction in carefully selected cases.
