A case report replanted fingers survived completely


Refers to the dorsal skin flap for thumb reconstruction J Fan dark Harbin City, Heilongjiang Province, the fifth hospital Tiankai Ming Huo Qibin Johnson Zhigang dry white star thumb in hand function plays an important role. 1986 we take into account the neurovascular pedicle of the food, the middle finger dorsal flap for thumb reconstruction surgery, after 24 cases of successful application of all results were satisfactory, the report is as follows t aim at the 24-bed material like spider,tory burch shoes, the male side L6, F 8 cases. Age 19N58 years. 14 gal of fresh wounds, old wounds lO side.

Old stump in the thumb injury to make a triangle base dorsolateral distal 1 × 2cm flap, the flap turned to the web space l, cross-cut bone ends scar Qu, exposed marrow. Will cut the iliac bone repair Qi refers to the bolt-shaped, insert the thumb stump marrow, the rejection of Kirschner wire fixation. Then the required length of thumb, in the food, the middle finger Building Design dorsal metacarpal flap area. First, health sub-index pillow snuffbox lateral incision to expose the first dorsal metacarpal artery and the port 1 『{c {【Beijing amidine, the proximal superficial branch of radial nerve. Then swim out of the index finger side of the artery skid, keep some subcutaneous tissue connected with the flap. Finally, repeated along the fascia of the index finger distal to the middle finger under the prayer from the dorsal and palm. In the food, between the middle finger means to retain a certain webbed, anti-manic off between the contracture of the flap, after all, relax tourniquet observed blood supply, blood supply to be identified normal skin, go to the thumb area, the index finger Hupi flap set in reference to the abdomen, side and back of the middle finger stitched. Xiao repair the tiger's mouth,mbt cipo, such as the location may change,ed hardy swimwear, so the index finger placed on the back side of the flap donor site spider to take a piece of thick cover to discuss this law only with double sets of arteries, to make up for r the first metacarpal single mother of dorsal vein blood did not work Ge constant lack of Coleman that hand back four with tales of arterial segments, namely, dorsal interosseous move crisp, kneeling on the back move Mi, dorsal metacarpal artery dorsal artery and digging. Dorsal metacarpal artery and deep palmar arch proximal to wear _ even in his hand sorrowful soil total fixed indemnity or palmar digital artery. All dorsal chu hyperactive children went to the election finger web, they all dispersed into a number of small supply of the two sticks I refer to the back of the bear skin. Xu Endor the support that the dorsal artery, although the classes are generally small, but it is not isolated, with the palm spider artery connected to pass, a complete three-dimensional hand uniform arterial structure based on specimens observed using methylene blue perfusion The range of flap blood supply can be food.

The case of New Zealand had to repair the thumb and a tiger at the back area home construction, will be 5 × 8cm dorsal skin cut enamel, the flap blood supply is still good to see a field: Death occurred.

Surgical indications: (L) pure degloving injury of the thumb: For degloving injury with this method not only has good shape, but also with the power cord off. (2) does not care who thumb replantation; severe local soft tissue injury, loss of replantation conditions may benefit rejection of bone and joint, tendon i guanidine cutting seed recycling. (3) thumb I. Lack of mortgages, to be built Tiger Tricholoma defect z I use the thumb carpometacarpal joint, is too basic intact thenar muscles can thumb reconstruction cases. Focus is embedded in complex reconstruction of its length and the tiger's mouth back flap repair using palm web space without affecting its length, an operation to complete. Use of free skin graft donor pairs, the metacarpophalangeal joint session of the song 20 can be avoided due to skin contracture after surgery, resulting in the metacarpophalangeal joints were followed up by clothing, skin graft area good shape, only slightly darker color of skin grafts, no 1 case joint activities by the meteorite. This approach has the advantage (1) simple, time-saving, reliable security barrier, (2) the use of metacarpophalangeal joint and carpometacarpal joint may be some early activity on the Palm functions with j (0) with good music and feel the blood series f ( 4) beautiful appearance, = period can be assembled nails. Experimental study of periosteal graft venous nutrition text see section 22. Page) Figure 2 into a vein more heat periosteal osteoblasts, increased bone matrix, bone marrow cavity of small beam gradually trend. 3, the periosteum can be seen around arteries become mature by the early trabecular bone and bone marrow cavity. Figure 4, the majority of free periosteal fibrous tissue necrosis alternative, only see the small pieces into the bone. Replantation of fingers that are all definitely survived from the case (see text page 234) Figure 1 and 2 before the situation ten lift off Duanmu Figure 3 ~ Yu-wood appearance and function of the situation after the 4r mouth ■ ■ ■ __ ■ 』‖ Yi. / With a ≯ ~ heavy rain If.
