BACKGROUND Congenital longitudinal deficiencies of the radius and thumb are known to be associated with one another; however, the details of their relationship are unknown. The purpose of this study was to determine whether increased severity of radial deficiencies is associated with increased severity of thumb deficiencies and to review the relationship(More)
The flexor digitorum superficialis is a diagastric muscle with a proximal muscle belly from which the tendons to the index, ring and little fingers arise. These tendons are not independent and are not good motors for non-synergistic transfers, such as for finger extension. The muscle and tendon to the middle finger arise separately and are therefore more(More)
Epineural neurorrhaphy under tension and interfascicular grafting, two methods of bridging gaps associated with loss of a nerve segment, were compared. After resection of a 2 cm length of both ulnar nerves in cats, one nerve was sutured under tension using an epineurial technique, and the other was repaired using multiple interfascicular sural nerve grafts.(More)
The complex clasped thumb deformity associated with a windblown hand requires correction of three distinct deficits: an adduction contracture of the thumb-index web space, a flexion-volar subluxation contracture of the thumb metacarpophalangeal joint, and severe hypoplasia of the superficial thenar muscles. Severe contractures of the thumb web space are(More)
PURPOSE Children with radial longitudinal deficiency have very short forearms. The Ilizarov method of distraction osteogenesis has been used to increase extremity length, but results differ with the underlying condition and the limb being lengthened. The purpose of this study is to examine retrospectively the outcomes of Ilizarov lengthening of the ulna in(More)
The abductor digiti minimi is one of several muscles described as transfers for restoration of thumb opposition, a critically important function. This operation, also known as the Huber opponensplasty, is most commonly used for reconstruction of opposition in children with type 2 or 3a thumb deficiency, when it is often combined with Z-plasty of the(More)
The formation of dentin and enamel in the abdominal wall in young pups was achieved by transplantation of the soft tissues of the developing tooth germ. An interesting finding was the cytomorphosis of the epithelium of the enamel organ. When this was transplanted so that the ameloblasts were in contact with the odontoblasts the cylindrical character of the(More)
To compare the results of epineurial and intrafascicular perineurial nerve repair techniques, ulnar nerves of 20 domestic cats were severed proximal to the medical humeral epicondyle. One nerve was repaired with No.8-O nylon by standard epineurial technique with the aid of three to five magnifications; the other nerve was repaired with No. 10-O nylon by(More)
