1/728. Plastic injection injury of the hand.

    A unique case of injection of plastic material into the hand is reported. Treatment was simple because the molten plastic solidified, separated readily from the surrounding tissues and could be withdrawn without fragmentation. There was no evidence of serious damage to the surrounding tissues by the plastic before it has cooled and set. The mechanism of the injury is explained and the need for simple safety precautions is noted. ( info)

2/728. Serratus anterior-rib composite flap: anatomic studies and clinical application to hand reconstruction.

    Because of its relative ease of dissection, increased length of the vascular pedicle, and excellent diameter for anastomosis, the serratus anterior-rib composite flap has been used to reconstruct bony and soft-tissue defects in the face and lower extremities. However, no data are available on optimal rib level or harvest location. The authors report the results of the vascular anatomy of this flap in 6 fresh cadavers and 2 clinical patients using this flap to reconstruct a defect in the hand. Arteriograms were performed through the thoracodorsal artery, and microscopic dissections were done at the rib periosteum. The sixth through the ninth ribs showed consistent filling of their respective intercostal vessels. The rib segments near the anterior axillary line had the most abundant communicating vessels between the serratus and the periosteum. In two patients, the serratus-rib composite free flap provided excellent bone and muscle length for reconstructing the first metacarpal defect. ( info)

3/728. thumb reconstruction in a bilateral upper extremity amputee: an alternative to the Krukenburg procedure.

    A 23-year-old man sustained traumatic loss of both hands. His left defective forearm underwent lengthening with a 3-cm segment of the ipsilateral radius; this was immediately followed by an ipsilateral second toe microvascular transfer to the stump of the radius to provide pinch. Two years after the procedure the reconstructed hand had recovery of both motion and sensibility. ( info)

4/728. gangrene of the hand: a complication of radial artery cannulation.

    radial artery cannulation for constant monitoring of arterial pressure and blood gases has become commonplace in the care of the seriously ill. The radial artery is readily accessible and is often regarded as carrying a negligible complication risk, because there is extensive collateral arterial flow in the hand. To the rarely reported cases of gangrene of the hand secondary to cannulation of the radial artery, this publication adds two, both survivors. One, a 46-year-old female with a clinical picture suggestive of mild Raynaud's disease, was treated by closed mitral commissurotomy; the second, a 44-year-old female, was treated for drug overdose complicated by cardiac arrest and renal shutdown.

5/728. upper extremity salvage using the tensor fascia lata flap: report of two cases.

    The tensor fascia lata pedicled flap was successfully used to salvage 3 severely injured upper extremities in 2 patients. Both patients had undergone 3 prior free tissue transfers without complete closure of their wounds. All 3 tensor fascia lata flaps (2 myocutaneous, 1 myofascial) survived entirely. We believe this flap offers a distinct advantage compared with the groin flap when pedicled flap coverage of the upper extremity is required. ( info)

6/728. Immediate autografting of bone in open fractures with bone loss of the hand: a preliminary report. case reports.

    Three patients with open fractures of the hand associated with bone loss were treated within four to six hours of injury by corticocancellous bone grafting and soft tissue coverage after meticulous debridement, copious irrigation of the wounds, and broad-spectrum antibiotics given intravenously. Long term follow-up was uneventful and showed that the graft had taken and healed well with early and full restoration of function and a good cosmetic result. Immediate corticocancellous bone grafting of an injured hand could be used in selected cases with well-debrided, surgically clean wounds as long as there is a rich blood supply. Adequate bone fixation, soft tissue coverage, and broad-spectrum antibiotics given intravenously will remove the risk of infection. hand architecture is corrected while wound contracture and secondary deformity are avoided. Both patients' discomfort and hospital costs are considerably reduced. ( info)

7/728. Impossible harvest of the posterior interosseous artery flap: a report of an individualised salvage procedure.

    Although the posterior interosseous artery flap represents a reliable technique to provide vascularised skin cover for the dorsum of the hand, the dissection of the flap is often very difficult because of anatomical variants. The weakest part of the vascularisation is the middle third of the posterior interosseous artery. Whenever it is discovered during the operation that such a flap is impossible to harvest, or likely to be unreliable, there is an immediate need to choose an alternative. Such a case is reported here. The individual anatomical situation allowed the dissection of a flap, the pedicle of which carried its blood supply from a perforating branch of the anterior interosseous artery. The technique described offers an individual solution to the problem of skin coverage when the harvest of the posterior interosseous artery is impossible. ( info)

8/728. Ultrasonic assistance in the diagnosis of hand flexor tendon injuries.

    In contrast to routine flexor tendon injuries, flexor tendon ruptures following blunt injury or re-ruptures following repair can be difficult to diagnose. The authors investigated the efficacy of using ultrasound to assist in the diagnosis. From 1996 to 1997, 8 patients underwent evaluation of the flexor tendons using an ATL HDI-3000 ultrasound machine with a high-resolution, 5 to 9-MHz hockey stick linear probe. Dynamic evaluation was performed in real time, simulating clinical symptoms. Six patients underwent surgical exploration. Sonographic diagnosis and intraoperative findings were correlated. Ultrasound was used to diagnose 3 patients with ruptured flexor digitorum profundus tendons. Mechanisms of injury included forceful extension, penetrating injury, and delayed rupture 3 weeks after tendon repair. Subsequent surgical exploration confirmed the ruptures and location of the stumps. Five patients had intact flexor tendons by ultrasound after forceful extension, penetrating injury, phalangeal fracture, crush injury, and unknown etiology. In 3 patients who underwent surgery for tenolysis, scar release, or arthrodesis, the flexor tendons were found to be intact, as predicted by ultrasound. The authors found ultrasound to be accurate in diagnosing the integrity of flexor tendons and in localizing the ruptured ends. They conclude that ultrasound is helpful in evaluating equivocal flexor tendon injuries. ( info)

9/728. helium vapour injury: a case report.

    We report a case in which quick freeze injury occurred to both hands by helium vapour at extremely low temperatures. At the time of injury the victim was wearing protective gloves which were removed quickly after the accident. This prompt removal of gloves reduced the depth and severity of the injury. Initially he was treated by rapid thawing by immersing the hands in luke warm water (37 degrees C) and administering heparin by drip to prevent microvascular thrombosis. Delayed skin grafting was performed with good functional recovery. The circumstances accompanying this injury and preventive measures are discussed. ( info)

10/728. Full-thickness burn to the hand from an automobile airbag.

    An 18-year-old male was involved in a single car motor vehicle accident in which the driver's side airbag was deployed. He presented to the trauma center with complex injuries to the left hand, lacerations to the scalp, and a full-thickness burn to the ulnar aspect of the right hand that included the hypothenar area and the fifth digit. The patient was admitted to the trauma center and received immediate consultation from the burn service. He underwent debridement and split-thickness skin grafting of 50 cm2 of the right hand on postburn day 3. The graft became necrotic and the patient underwent debridement of the skin and the abductor minimi muscle of the right hand on postburn day 32. Split-thickness skin grafting and release of flexion contracture were successfully completed 18 days later. The police and fire departments reported that the airbag showed signs of thermal destruction. Upon request, Honda motors submitted information from the TRW safety systems and material safety data sheet (Mesa, Ariz, issued 1989) that showed that airbag canisters contain the chemicals sodium azide and cupric oxide. water may react with sodium azide to form highly toxic and explosive hyfrazoic acid. These chemicals are converted to sodium hydroxide, which can cause significant chemical burns. In addition, these chemicals may ignite when exposed to live electrical wires or temperatures greater than 300 degrees F. We conclude that burns associated with damaged deployed airbags in motor vehicle accidents may be the results of both chemical and thermal injury. The extent of the burn wound may be underestimated, as our case illustrates. Full-thickness burns resulting from airbag deployment may require more aggressive initial debridement and treatment.
