schemia time is one of the important factors influencing the success of limb replantation. Proper tissue handling, including appropriate cooling, has been shown to prolong tissue survival in both experimental and clinical studies. Recent reports have shown that digits may be successfully replanted after prolonged periods of cold ischemia. However, replantation at more proximal levels involves the additional problems of myonecrosis with potential for infection and renal toxicity due to myoglobin products. We have recently cared for a patient who underwent successful replantation of a complete wrist disarticulation after 54 hours of cold ischemia. CASE REPORT The patient, a 15year-old girl, sustained a sharp blade injury to the wrist. The hand was totally severed except for a thin remnant of the intercarpal ligament (Fig. 1). Initial treatment involved completion of the wrist disarticulation and closure of the amputation stump at an outside hospital after

a delay of several hours because of the self-inflicted nature of the injury. The warm ischemia time was estimated to be 3 hours. After completion of the amputation, the hand was placed into a refrigeration unit for future anatomic dissection. The temperature of this refrigeration unit was estimated at 2” to 5” C. The patient’s father, who was a visiting scientist outside the country, received word of the injury after a 36hour delay. He voiced concerns about possible hand replantation. After discussion with both the patient and other family members. a strong desire for reattachment resulted in the decision to transfer the patient to the Lanzhou General Army Hospital in Lanzhou, People’s Republic of China. At the time of transfer the amputated part was found on a windowsill, but the period of time it was out of the refrigerator was not known. The ambient temperature during this period was estimated to range from 3” to 9”. At the time of replantation the carpal bones were excised because of extensive soft tissue trauma. A revascularization procedure was carried out. First the radial artery was anastomosed with Nakiyama ring couplers. The ulnar artery was then grafted with a 6 cm length of saphenous vein. After observation of good flow, four venous anastomoses were carried out, also with the use of Nakiyama devices. Prophylactic fasciotomies were performed because of the intense swelling noted after restoration of the vascular supply. Obviously necrotic tissue from the thenar. hypothenar, and intrinsic compartments was debrided. No muscle biopsy specimens were taken. The incisions were closed over drains. The decision to delay tendon and nerve repair was based on the belief that this could be performed later if the hand replantation proved viable. The total delay from injury to restoration of arterial flow was estimated at 54 hours. Twenty-three days later a direct ulnar neurorrhaphy was performed. as well as an ipsilateral sural nerve grafting of a

Because of a tendon deficit, a common proximal flexor tendon was used for both the third and fourth digits. Very little intrinsic muscle tissue remained. No intrinsic muscle biopsy was performed.

The patient was first seen at the Mayo Clinic 6 months after replantation. At that time she had well-healed surgical and traumatic incisions with shortening of the wrist. Her wrist and thumb were unstable. She demonstrated a palpable ulnar pulse and a Doppler audible radial pulse. There was physiologic capillary refill in all five digits. Neurologically, she perceived deep pressure sensation in the median, ulnar, and radial nerve distributions. She was not able to discriminate between sharp and dull, and she had no two-point sensibility. The wrist was positioned in palmar flexion and ulnar deviation, and the first metacarpal was adducted to the plane of the palm. Passive digital motion was nearly full in all digits.

An electromyogram showed a complete median neuropathy with early evidence of abductor digiti minimi reinnervation. The initial reconstructive procedure was performed 7 months after replantation and consisted of a radius-to-first, second, and third metacarpal arthrodesis with iliac crest graft and Kirschner wire fixation. Wrist fixation was supplemented with tension band wiring (Fig. 2). The first metacarpal was positioned in midopposition to the plane of the palm. The radius-to-metacarpal fusions healed uneventfully. After this the patient was placed in a supervised mobilization program for the fingers. This program included the use of ultrasound, gentle prolonged passive stretching, and resistance. Her psychiatric status remained stable.

At follow-up 30 months after replantation, the patient demonstrated a complete range of passive finger motion. Active finger extension to the metacarpal plane was present, and active finger flexion to the midpalmar line was present for the index and long fingers. The patient lacked complete flexion to the midpalmar line by 1.5 and 2 cm for the ring and small fingers, respectively (Fig. 3). She demonstrated very weak activity of the first dorsal interosseous muscle but otherwise had no intrinsic motor function. The presence of protective sensibility, with the ability to discriminate sharp from dull and heat from cold, and the presence of sudomotor activity were confirmed. She reported that she used the hand for grasp and assisted functions in most activities of daily living. Her major complaints were of her inability to flex her long and ring fingers independently and of impaired active flexion of the small finger, both of which made keyboard activities difficult. At that time she was advised to undergo

DISCUSSION This report of a successful wrist replantation after a 54-hour period of cold ischemia illustrates a number of interesting challenges in both the initial and late phases of treatment. Early problems include the prolonged ischemia time and soft tissue defects. Late problems include wrist instability, thumb stance, combined low nerve lesions, and the loss of intrinsic muscle tissue. A number of case reports and series have reported successful replantation after prolonged periods of ischemia. The value of immediate and appropriate tissue cooling in prolonged tissue survival is well established. However, the acceptable range of normothermic and hypothermic ischemic storage remains controversial. There is little question that the tolerance of composite tissue for ischemia is dependent on the quantity of contained skeletal muscle.’ Digit replantation has been reported after a hypothermic ischemic interval as long as

94 hours.’ Experimentally, successful revascularization has been carried out with anoxic periods exceeding 100 hours. We are aware of successful replantation of major human limbs with ischemic times of up to 13% hours3 and of successful human hand replantation after anoxic intervals of 7 hours4 and 36 hours.” We believe this case documents the longest anoxic period yet reported for successful hand replantation. We further believe that the functional result attained confirms the value of hand replantation even after such a prolonged ischemic interval.

Multiple-level amputation has been cited as a contraindication for replantation surgery. ’ We believe the paucity of reported cases of multiple-level replantations in the English-language literatureze4 is indicative of the hesitancy to undertake such a procedure. We report our experience with a three-level amputation, in which the hand was replanted, and discuss the surgical techniques and functional results.

Case report A 25year-old right-handed factory worker sustained a three-level amputation when his right hand was caught in a vacuum mold machine (Figs. 1 and 2). Proximally, the amputation occurred across the bases of the metacarpals and obliquely across the thenar eminence, leaving the wrist flexors and extensors intact. The second level of the injury passed obliquely from the base of the proximal phalanx of the small finger across to the proximal shaft of the proximal phalanx of the index finger. The third level involved only the three ulnar digits, passing just distal
