Distant flaps.

Tube pedicle flaps, jump flaps, and waltzed tube pedicle flaps are now only of historical note. The random abdominal flap and vertical hypogastric flap, the first axial flap described, are in their twilight years. The free flap is the current champion for composite tissue reconstruction, the only exception being the functioning myocutaneous transfers that are available in upper extremity reconstruction. The well planned distant flap still can provide high quality skin and subcutaneous tissue for upper extremity coverage. Utilization of this tool, however, requires an overall appreciation and understanding of flap physiology, the ability to shrewdly analyze the reconstructive needs of a given defect, and the skills and knowledge to commit the patient to what is inevitably a two-stage operation spaced over 3 to 5 weeks.

Coverage of a shoulder wound with a deltoid muscle flap.

An unusual and severe injury to the soft tissues of the shoulder with exposure of the humeral head and glenohumeral joint is presented. The principles of muscle transposition were applied to rotation of the deltoid muscle in achievement of wound closure. Healing was rapid and satisfactory, and a useful upper extremity was salvaged.

Staged reconstruction of flexor tendons with a silicone rod and a "pedicled" sublimis transfer.

We report the results in 11 cases of secondary flexor tendon reconstruction, employing a silicone rubber rod and a sublimis/profundus tenorrhaphy in the first stage, then hinging out the sublimis tendon on the profundus motor at the second stage. Achievement of a healed proximal tenorrhaphy before the second stage allows (1) inspection of the proximal tenorrhaphy (with assessment of its location, apperance, and strength) and (2) early postoperative motion in a controlled range (with greater confidence in the proximal tenorrhaphy, as rupture after free tendon grafting is not uncommon. The functional results attained were comparable to those in other series of secondary flexor tendon reconstructions.

The irrigation jet: an aid in microvascular surgery.

Techniques for manipulating and positioning blood vessels during microvascular surgery which utilize a jeweler's forceps tend to inflict significant trauma to the wall and to the intima of the vessel. An irrigation jet device was designed which allows atraumatic positioning of the vessel, gentle and controlled dilation , and better visualization. With this device rat arteries and veins with an external diameter of 0.6 mm. were joined. Upon examination 3 weeks later, over 95 percent remained patent. In addition, vessels of 0.2 to 0.4 mm. were anastomosed successfully with a long-term patency rate of approximately 50 percent. The device has been found to be useful in clinical replantation and revascularization problems in man.

Major venous injuries and bullet wounds.

A review of the reported incidence, management and results of treatment of major vein injuries is presented and a brief account given of the mechanism of vascular damage by high-velocity bullet wounds. This paper reports 3 cases of isolated major venous injury caused by high-velocity bullets. Repair was performed in each case. Two patients survived with a good short-term clinical result. The third patient died during operation. The advantages of repairing injured veins are discussed.
