OBJECTIVE: To reduce amputation rate of severe electrical burn of wrist and to promote partial recovery of the injuried hand. METHODS: From 1987 to 1999, 44 cases, with 55 limbs of severe electrical burn were classified into 4 types, according to criteria of Dr Shen Zuyao, and were all treated by primary adequate decompression, timely debridement, reconstruction of blood circulation in cases complicated with blood vessel injury, and skin flap grafting from chest, abdomen or inguinal area, followed by treatment of anti-coaggluation and anti-infection. Once the wound healed, auto- or allo-transplantation or transferring of tendons were performed to repair tendon defect, and auto-nerve or fetal nerve transplantation performed for nerve defect. RESULTS: After the primary treatment of the 55 burned limbs, all limbs of type IV were amputated, and most of other 3 types survived. The function, including sensation and movement, of survived hands partially recovered. CONCLUSION: Primary reconstruction of blood circulation, cover of wound with skin flap, and timely repair of sensation and motor function are very crucial approach to reduce amputation rate and to promote the survived hand function of severe electrical burns of wrists.
OBJECTIVE: To review the recent progress in the treatment of wrist disorder by limited intercarpal arthrodesis and the related experimental study. METHODS: Recent original articles related to limited intercarpal arthrodesis, including clinical practice and experimental study, were extensively retrieved and carefully analyzed. RESULTS: Limited intercarpal arthrodesis could relieve pain and stabilize the wrist joint with partial motion. CONCLUSION: With suitable indication and well selected operation approach, the limited intercarpal arthrodesis should be the optimal surgical intervention than total carpal athrodesis in the treatment of wrist disorder.
Objective
To study the anatomical basis of micro transverse flap pedicled with the superfical palmar branch of radial artery from the palmar wrist for using this free flap to repair soft tissue defect of the finger.
Methods
Thirty-eight fresh upper limb specimens (22 males and 16 females; aged 26-72 years with an average of 36 years; at left and right sides in 19 limbs respectively) were dissected and observed under operating microscope. Two specimens were made into casting mould of artery with bones, and 2 specimens were injected with red emulsion in radial artery. Thirty-four specimens were injected with 1% gentian violet solution in the superfical palmar branch of the radial artery. A transverse oval flap in the palmar wrist was designed, the axis of the flap was the distal palmar crease. The origin, distribution, and anastomosis of the superfical palmar branch of the radial artery were observed.
Results
The superficial palmar branch of the radial artery was constantly existed, it usually arises from the main trunk of the radial artery, 1.09-3.60 cm to proximal styloid process of radius. There were about 2-5 branches between the origin and the tubercle of scaphoid bone. The origin diameter was 1.00-3.00 mm, and the distal diameter at the styloid process of radius was 1.00-2.90 mm. The venous return of flap passed through 2 routes, and the innervations of the flap mainly from the palmar cutaneous branch of the median nerve. The area of the flap was 4 cm × 2 cm-6 cm × 2 cm.
Conclusion
The origin and courses of the superficial palmar branch of the radial artery is constant, and its diameter is similar to that of the digital artery. A transverse oval flap pedicled with the superfical palmar branch of radial artery in the palmar wrist can be designed to repair defects of the finger.
Objective
To investigate the clinical application of micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist to repair skin defect of finger.
Methods
Twenty-six cases (26 fingers) with skin defect of finger were repaired with micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist between December 2011 and February 2013. There were 20 males and 6 females with the average age of 31.5 years (range, 20-56 years). The causes of injury included cutting injury in 20 cases and crushing injury in 6 cases. The time from injury to admission was 1-5 hours with an average of 2 hours. Injured fingers included thumb in 6 cases, index finger in 6 cases, middle finger in 6 cases, ring finger in 4 cases, and little finger in 4 cases; the locations were the dorsal side of the finger in 6 cases, lateral side in 6 cases, and the volar of the finger tip in 14 cases; there were 4 cases on the proximal phalangeal skin, 8 cases on the middle phalangeal skin, and 14 cases on the distal phalangeal skin. The defect area ranged from 2.0 cm × 1.5 cm to 4.0 cm × 2.0 cm, and the flap area ranged from 2.5 cm × 2.0 cm to 4.5 cm × 2.5 cm. All the donor sites were directly sutured.
Results
The flaps of 25 cases survived well after operation, and wound healed by first intention； 1 case had partial necrosis and the wound had a scar healing by changing dressing. All cases were followed up 6-12 months (mean, 10 months). The color and appearance of the flaps were satisfactory with tender texture. The two-point discrimination of the flap was 5-8 mm (mean, 6.8 mm). The donor sites healed primarily without scar contracture and limitation of wrist flexion or extension.
Conclusion
The micro transverse flap pedicled with superficial palmar branch of radial artery from palmar wrist is a good option to repair skin defect of finger. It has the advantages of hidden donor site, the same operative field, great comparability of flap and finger skin, and it can be used as a vascularized tendon or nerve graft.
Objective To summarize the therapeutic effectinevess of incorporating pedicled retrograde flap of forearm transplantation for reconstructing severe contracture of the first web space and wrist. Methods Between November 2005 and February 2010, 26 patients with severe contracture of the first web and wrist were treated. There were 18 males and 8 females with an average age of 27 years (range, 12-45 years). The locations were the right sides in 15 cases and the left sides in 11cases. The injury reason included hot water scald in 7 cases, explosion hurt in 5 cases, traffic accident in 3 cases, hot pressing in 5 cases, and flame burns in 6 cases. The duration of scar contracture ranged from 6 to 26 months with an average of 11 months. According to the evaluation standard by GU Yudong et al., all had severe contracture of the first web space, and concomitant injuries included adduction deformity thumb, l imitation of the thumb extension and opposition function, and carpometacarpal flexion joint deformity. After scar contracture was released, the defect size ranged from 5.8 cm × 4.5 cm to 11.3 cm × 7.2 cm, which were repaired by the incorporating pedicled retrograde flap of forearm of 6.5 cm × 5.0 cm to 12.5 cm × 8.0 cm at size. The donor sites were directly sutured or repaired with skin graft. Results Bl ister and partial necrosis occurred at the distal end of the flaps in 2 cases, which were cured after dressing change. The other flaps survived and wounds healed by first intention. Incisions at donor sites healed by first intention. Twenty-six patients were followed up 6 to 24 months (mean, 15 months). The patients had functional recovery in thumb adduction and opposition at different degrees. At 6 months after operation, according to the Swanson et al. AMA system for total thumb activity, the total thumb function was improved significantly, and according to Jensen et al. measurement, the width and angle of the first web space were significantly increased, all showing significant differences (P lt; 0.05). Conclusion Incorporating pedicled retrograde flap of forearm transplantation for repairing severe contracture of the first web space and wrist could augment the first web space and improve the wrist flexible function.
