Reconstruction of the Amputated Finger Tip with a Triangular Volar Flap: A New Surgical Procedure

A triangular volar flap has been used successfully for the reconstruction of amputated finger tips. It can be applied to most finger amputations except those with extensive soft-tissue loss on the volar side of the amputated finger tip. The distally based triangular flap, carefully prepared with intact nerve and blood supply, is advanced over exposed bone and approximated to the nail matrix. The V incision is closed by converting it to a Y.

Replantation of digits and hands: Analysis of surgical techniques and functional results in 71 patients with 86 replantations

Defining replantation as the restoration of a completely amputated part as opposed to simply restoring circulation to an incompletely severed part, the results of replantation of 86 completely amputated parts in 71 patients performed from January, 1970, to December, 1975, were studied. Twenty-eight, or 32.5 percent, were the result of sharp severances of the part; localized crushing accounted for 56, or 65.1 percent. Two were classified as degloving injuries. Twelve amputations were transmetacarpal, six were at the metacarpophalangeal joints, 14 through the proximal phalanx, 15 at the proximal interphalangeal joint, 21 in the middle phalanx, 13 at the distal interphalangeal joint, and five through the distal phalanx. The technique consisted of bone shortening and fixation and repair of all tendons and nerves if possible. Veins are repaired first at least two for each artery, and heparinized saline and lidocaine are used locally. Irrigation of the vessels is not done, but an intravenous bolus of 3,000 U. of heparin is given when the anastamoses are completed. Aspirin and low molecular weight dextran are given for 3 to 7 days. For the more distal replantation, heparin may be used. Antibiotics are given. In the total series of 86 completely amputated hand units, 52 were unsuccessful, primarly due to vascular thrombosis and usually on the venous side. In the year 1975 a success rate of 69.2 percent was achieved, whereas in the last 50 replantations, done between Jan. 1, 1976, and Oct. 15, 1976, the success rate was 90 percent. Results improved with more experience in the technique and with more careful selection of patients.

Reconstruction of severe transmetacarpal mutilating hand injuries by combined second and third toe transfer

This paper reports on nine instances of combined second and third toe-to-hand transfers in eight patients for severe transmetacarpal mutilating hand injuries. In four cases, the transfer included an innervated flap from the fibular side of the great toe to provide sensibility to a previously constructed osteoplastic thumb. Prehensile.function was significantly improved by providing chuck or tripod pinch as well as improved pulp-to-pulp and lateral pinch. At a mean follow-up of 20.3 months, there was only one failure.

Reversed cross-finger subcutaneous flap

The cross-finger subcutaneous flap has been successfully used to reconstruct the avulsed eponychial skin fold and cover large nail bed defects with exposed bone denuded of periosteum. Satisfactory new eponychial skin fold and nail growth were achieved.

Arthritis of the trapezial articulations treated by prosthetic replacement.

This paper reviews experience with thirty-six trapezial replacements over a period of six years. The indications for replacement are given, the group of patients analysed and the technique outlined, with particular attention given to tendinous reinforcement of the capsular repair. The results with regard to pain, dislocation and other complications are recorded. The causes of dislocation and its prevention are discussed.

The “antenna” procedure for the “hook-nail” deformity

The hook-nail deformity is a relatively common problem after fingertip amputations. It is usually ignored but can be quite disabling. This deformity can be corrected by a carefully planned operation. Most of the curved nail plate is removed, the pulp is reflected from the distal phalanx out to a normal contour, and then the full thickness of the nail bed is elevated off the distal phalanx and splinted by multiple small Kirschner pins in a straight position. The defect created is covered with a cross finger flap.

History of thoracic outlet syndrome

Thoracic outlet syndrome (TOS), a condition in which neurovascular structures in the thoracic outlet region are compressed, can be caused by anatomical abnormalities or acquired changes in the soft tissues and bony structures in the region. The brachial plexus is the most frequently affected structure. TOS is one of the most difficult neurovascular compressions in the upper extremity to manage because of the variability of complaints and the high risk associated with surgical treatment.

The cross thumb to index finger pedicle.

By careful technique the dorsum of the thumb can be used as a donor area to cover exposed bone of index fingertip amputations and, in certain cases, avulsions of the nailbed. In this procedure an oblique, radially based flap from the dorsum of the proximal phalanx is used.

Thoracic Outlet Compression Syndrome Caused by a Schwannoma of the C7 Nerve Root

This is the first report of a schwannoma originating from the C7 nerve root causing thoracic outlet compression syndrome. The patient was a 30-year-old woman with a 3-year history of numbness on the radial side of the left hand, left arm tiredness, nocturnal pain in the left forearm and pain in the left elbow, shoulder and neck. Conservative treatment and previous operations, including carpal tunnel release and first rib resection, provided no relief. A left scalenectomy was performed. During the removal of the anterior scalene muscle, a mass approximately 3 cm long and 1.5 cm in diameter was noted under the anterior scalene muscle involving the C7 nerve root. The tumour was encapsulated and covered with attenuated and stretched nerve fascicles. It was completely excised without disturbing the nerve fascicles. The clinical impression was schwannoma, which was confirmed on pathological examination.
