To summarize the effectiveness of the improv ed surgical techniques in fasciocutaneous flaps of the limbs. MethodsFrom February 1999 to December 2005, 58 patients (39 males, 19 females, aged 1068 years) underwent repairs of the skin defects with improved fasciaocu taneous flaps of the limbs. Twentyone patients had the skin defects in front of the tibial bone in the middle and lower parts, 12 patients had the skin defect s in the heels, 16 patients had the skin defects in the ankles, 3 patients had t he skin defects around the knees, 1 patient had a wide sacrococcygeal bedsore, and 5 patients had the skin defects in the wrists and hands. The wounds ranged in size from 5 cm×3 cm to 18 cm× 12 cm. According to the wound lo cations, the following flaps were selected: 4 cutaneous antebrachii medialis nerve and basilic vein fasciocutaneous flaps, 1 cutaneous antebrachii lateralis nerve and cephalic vein fasciocutaneous flap, 3 saphenous nerve and great saphenousvein fasciocutaneous flaps, 1 cutaneous nerve of thigh posterior fasciocutaneous flap, 32 reverse sural nerve and saphenous vein fasciocutaneous flaps, and 17 reverse saphenous nerve and great saphenous vein fasciocutaneous flaps. The dissected flaps ranged in size from 6 cm× 4 cm to 18 cm× 13 cm. The donor wounds underwent straight sutures in 39 patients, and the skin grafting (6 cm×3 cm to 13 cm× 6 cm) was performed on 19 patients after the donor wounds were closed. Results The wounds healed by first intention, and the flaps survived completely in 54 patients. The flaps developed partial necrosis in 4 patients. The followup for 120 months (average, 8 months) revealed that the flaps had a satisfactory appearance with a soft texture and the function was also satisfactory. Conclusion A fasciocutaneous flap of the limbs is an ideal flap for repairing defects in the skins and soft tissues of the limbs. The survival rate of the flap can be further improved by an improvement of the surgical techniques.
ObjectiveTo explore the effectiveness of retrograde island neurocutaneous flap pedicled with lateral antebrachial cutaneous nerve in the treatment of soft tissue defect of the hand.
MethodsBetween October 2011 and December 2013, 17 cases of skin and soft tissue defects of the hands were treated. There were 8 males and 9 females, aged 23-62 years (mean, 44 years). Of them, defect was caused by trauma in 13 cases, by postoperative wound after degloving injury in 2 cases, and by resection of contracture of the first web in 2 cases; 13 cases of traumas had a disease duration of 2-6 hours (mean, 3.5 hours). The defect sites located at the back of the hand in 5 cases, at the radial side of the palm in 4 cases, at the first web in 2 cases, at the palmar side of the thumb in 4 cases, and at the radial dorsal side of the thumb in 2 cases. The bone, tendons, and other deep tissue were exposed in 15 cases. The defect size varied from 3 cm×3 cm to 12 cm×8 cm. The size of the flaps ranged from 3.6 cm×3.6 cm to 13.2 cm×8.8 cm. The lateral cutaneous nerve of the forearm was anastomosed with the cutaneous nerve of the reci pient sites in 9 cases. The donor sites were repaired by free skin graft or were sutured directly.
ResultsThe other flaps survived, and obtained healing by first intention except 2 flaps which had partial necrosis with healing by second intention at 1 month after dressing change. The skin graft at donor site survived, and incisions healed by first intention. All patients were followed up 5-30 months (mean, 12 months). The flaps had good color and texture. Flap sensory recovery of S2-S3+ was obtained; in 9 cases undergoing cutaneous nerve flap anastomosis, the sensation of the flaps recovered to S3-S3+ and was better than that of 8 cases that the nerves were disconnected (S2-S3). The patients achieved satisfactory recovery of hand function. Only 2 cases had extended limitation of the proximal interphalangeal joint. At last follow-up, according to the Chinese Medical Society of Hand Surgery function evaluation standards, the results were excellent in 15 cases and good in 2 cases.
ConclusionRetrograde island neurocutaneous flap pedicled with lateral antebrachial cutaneous nerve is an effective way to repair skin defects of the hand, with the advantages of rel iable blood supply and simple surgical procedure.
To investigate the operative method of repairing soft tissue defect of finger with modified reverse dorsal digital fascia flap and its cl inical effect of preventing and treating venous crisis. Methods From February 2005 to March 2007, 19 cases (22 fingers) with soft tissue defect of finger were treated, including 14 males (17 fingers) and 5 females (5 fingers) aged 2-62 years old (median 26 years old). There were 8 cases of cutting injury, 6 cases of crush injury, 4 cases of avulsion injury, and 1 case of hot crush injury, involving 3 thumbs, 7 index fingers, 6 middle fingers, 4 ring fingers and 2 l ittle fingers. The size of soft tissue defect was 1.5 cm × 0.8 cm-5.5 cm × 1.5 cm, and the time from injury to operation was 2-11 hours(average 7 hours). The axis of flaps was the l ine of transverse striation of fingers via dominant artery. The flaps were deflected dorsally, as “b” or “d”, to cover the wounds. Reverse dorsal digital fascia flaps 1.8 cm × 1.0 cm-6.0 cm × 2.0 cm in size were adopted to repair the defects. The donor site underwent skin grafting fixation. Results All flaps survived, without venous crisis and obvious swollen. The grafted skin in the donor site all survived. All patients were followed for 6-18 months (average 11 months). Postoperatively, color and texture of the grafted flaps were similar to that of normal skin, and the pulp of the fingers was normal. The two-point discrimination was 8-11 mm, and the activities of interphalangeal joint of all injured fingers were normal. Conclusion The modified reverse dorsal digital fascia flap is ideal for repairing soft tissues defects of the fingers, and can decrease the occurrence of venous crisis.
ObjectiveTo investigate the operative method of repairing soft tissue defect of the thumb with modified radial dorsal fasciocutaneous flap and its effectiveness.MethodsBetween June 2015 and December 2016, 15 patients with volar or dorsal defects of the thumb were treated with modified radial dorsal fasciocutaneous flaps which distal pedicles were cut off. Of 15 cases, 11 were male and 4 were female, aged 35-70 years (mean, 46 years). The causes of injury included crush injury in 12 cases and avulsion injury in 3 cases. Because all patients had volar or dorsal defects of the thumb which were accompanied by tendon or bone exposure, they had no condition or desire to replant. There were 12 cases of volar defect of thumb and 3 cases of dorsal defect. The area of defects ranged from 2.0 cm×1.2 cm to 3.0 cm×2.5 cm. The time between injury and operation was 16 hours to 2 days (mean, 30.4 hours). The radial dorsal fascio-cutaneous flaps of 2.3 cm×1.5 cm to 3.3 cm×2.8 cm in size were adopted to repair defects. The donor sites were directly sutured.ResultsAll flaps survived, and no severe swelling or tension blister occurred. The donor sites and wounds healed by first intention. All patients were followed up 3-12 months (mean, 6 months). The color and texture of the grafted flaps were similar to those of normal skin, with no bloated appearance. According to total active motion standard at last follow-up, the finger function was excellent in 8 cases and good in 7 cases.ConclusionModified radial dorsal fasciocutaneous flap of the thumb is a reliable flap with easy dissection and less trauma in repair of soft tissue defects of the thumbs, and satisfactory clinical outcome can be obtained.
