Index Finger Pollicization for Treating a Congenitally Nonfunctioning Thumb in Patients With Radial Longitudinal Deficiency
(Yuzuncu Yil Universitesi Tip Fakultesi, 2014) Kömürcü, M.; Yüce, S.; Yavuz, O.Y.; Uraş, İ.; Uygun, M.; Kürklü, M.
Radial longitudinal deficiency (radial club hand) is a congenital deformity in the upper extremity that can present with a range of thumb deficiencies. A variety of surgical procedures to correct for absence of a thumb have been described, such as pollicization, osteoplastic reconstruction, toe to hand transfer, and extension with distraction. We have reviewed 8 index finger pollicizations in 6 patients after correction of the radial club hand deformity through wrist centralization. Four hands used were the dominant hand. Buck-Gramcko’s technique was used with a mean age of 4.6 (range from 2 to 14) years. The mean follow-up time was 6 (range from 2 to 10) years. The mean active range of motion at the pollicized digit was 121.4 (range from 83 to 150) degrees. The result was considered excellent in 5 cases (62.5%), good in 2 cases (25%), and fair in 1 case (12.5%) in accordance with Percival’s scoring system; none of the outcomes were poor. The younger patients adapted easier. Index finger pollicization is a method that provides dramatic improvement to hand function in thumb aplasia or severe hypoplasia, which may be preferred in treatment. The operations improved hand cosmetic appearance and functional ability. © 2014, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Our Experiences in the Surgical Treatment of Bayne Type Iii and Iv Radial Longitudinal Deficiencies
(TIP ARASTIRMALARI DERNEGI, 2015) Kömürcü, M.; Yüce, S.; Yavuz, O.Y.; Uraş, İ.; Uygun, M.; Kürklü, M.
Radial longitudinal defciencies are characterized by radial deviation of the wrist, a short and bowed forearm and a non-functional or absent thumb. The deformity is caused by varying degrees of underdevelopment and malformation including hypoplasia of the bones, joints, muscles, tendons, ligaments, nerves and vessels. This study describes our results from centralization in 8 limbs with Bayne type III-IV radial longitudinal defciencies. We reviewed 8 limbs from 6 patients with a centralization performed between 2002 and 2010. The median patient age at the time of the operation was 2.75 years (range 2-14 years). The sex ratio was 4 male and 2 female. All patients underwent centralization. One patient had an additional 6.5 cm elongation of the ulna bone by means of a circular external fxator (CEF). The median follow-up time from centralization was 4,5 years (range 2-10 years). The result was considered to be excellent in 4 cases, good in 3 cases and fair in 1 case. Radial deviations regenerated in all cases. During follow-up, a radial deviation of 15 degrees developed in one patient; this deviation did not require surgical correction. Hand and wrist movements were within acceptable levels. Movement and function of the wrist and forearm can be obtained through centralization of the wrist and ulnar elongation when necessary. A cosmetically pleasant appearance can be ensured. © 2015, TIP ARASTIRMALARI DERNEGI. All rights reserved.
