OBJECTIVE: To explore a new surgical management of multiple fingers degloving injury. METHODS: In 1994 to 1997, 47 cases with multiple fingers degloving injury were sutured by two reverse "s"-type skin flaps on abdominal flank. RESULTS: The skin flaps in 46 cases survived and the wounds obtained primary heal. CONCLUSION: The application of abdominal flank "s"-type skin flap is reliable and convenient in the treatment of multiple fingers degloving injury.
In extensive frictionavulsion injuries, part of the injuried skin was still viable, so that total excision of the avulsed skin should be avoided. After debridememt, sutured the avulsed skin flap in situ temporarily and took a split-thickness graft from it. If bleeding occurred from the splitted surface of the dermis which was meant that part of the skin was alive. Along the border between the bleeding and nonbleeding area, the nonbleeding area of skin was excised. This could preserve the viable skin to the maximal extent. From July 1991 to May 1992, the viability of the skin in 8 avulsion injuries was judged. The maximal avul sed area was 13% and the minimal was 6% of the total body surface. After the treatment, 90% of the avulsed skin was alive. The appearance was satisfactory.
OBJECTIVE In order to solve the difficult problem of one-stage repair of degloving injury of multiple fingers, the common pedicled ilio-inguinal-hypogastric subdermal vascular network skin flap was designed and the multi-lobes skin flap was performed subsequently. METHODS From 1993 to 1996, there were 5 cases with degloving injuries of multiple fingers were treated by this flap. There were 2 males and 3 females and the age ranged from 7 to 19 years old. RESULTS After operation, the pedicles of the flap was detached between 12 to 16 days and all of the flaps survived completely. Patients were followed up for 6-18 months. After repair, the contour and skin colour of the digits were excellent, and the motion of the interphalangeal joints and skin sensation were good. CONCLUSION The conclusion was as follows: The newly designed skin flap was characterized by the advantages of duration of treatment being short, excellent contour and more rapid recovery of function. It could be used for one-stage repair of degloving injury of multiple fingers.
OBJECTIVE: To investigate the clinical effects of the microsurgical treatment for the skin-degloving injury of the whole hand or foot. METHODS: From March 1984 to October 2001, we treated 6 cases of skin-degloving injury of the whole hand and foot. In 2 cases of skin-degloving hands, one was treated with free great omentum transplantation plus skin graft, the other with pedical abdominal S-shaped skin flap as well as mid-thick skin graft. In 4 cases of skin-degloving injury of the foot, 2 cases was repaired with free latissimus dosi musculocutaneous flap, 1 case with distall-based lateral skin flap of the leg and 1 case with free tensor fasciae latae muscle flap. The flap size ranged from 7 cm x 9 cm to 22 cm x 15 cm. One case was operated on the emergency stage, the other 5 cases on the delayed stage. The delayed time ranged from 2 to 14 days with an average of 6.6 days. RESULTS: All the flaps survived. After 1-2 year follow-up, the appearance and function of the hand and the foot were good. CONCLUSION: Microsurgery technique in repairing skin-degloving injury of the whole hand and foot can achieve good results. The keys to success are thorough debridement of the recipient area, appropriate selection of the donor site, good vascular anastomosis and active postoperative rehabilitation.
Morel-Lavallée lesions manifest as a type of subcutaneous closed degloving injury, where the external violence creates a potential space between the subcutaneous tissue and the deep fascia, leading to the accumulation of fluid and the formation of infection within the cavity. The primary causes of Morel-Lavallée lesions include high-energy trauma, blunt force injuries, or compression injuries, with the lesions typically located around the greater trochanter. Due to the potential for clinical oversight, these lesions may result in complications such as infection at the fracture site. In light of these circumstances, this article provides a comprehensive review of the etiology, epidemiology, pathological mechanisms, clinical manifestations, imaging features, differential diagnosis, complications, and treatment modalities of Morel-Lavallée lesions. The aim is to enhance the awareness of trauma orthopedic surgeons regarding this injury, thereby offering insights for clinical decision-making.
ObjectiveTo investigate the effectiveness of dorsalis pedis flap series-parallel big toe nail composite tissue flap in the repairment of hand skin of degloving injury with tumb defect. MethodsBetween March 2009 and June 2013, 8 cases of hand degloving injury with thumb defect caused by machine twisting were treated. There were 7 males and 1 female with the mean age of 36 years (range, 26-48 years). Injury located at the left hand in 3 cases and at the right hand in 5 cases. The time from injury to hospitalization was 1.5-4.0 hours (mean, 2.5 hours). The defect area was 8 cm×6 cm to 15 cm×11 cm. The thumb defect was rated as degree I in 5 cases and as degree II in 3 cases. The contralateral dorsal skin flap (9 cm×7 cm to 10 cm×8 cm) combined with ipsilateral big toe nail composite tissue flap (2.5 cm×1.8 cm to 3.0 cm×2.0 cm) was used, including 3 parallel anastomosis flaps and 5 series anastomosis flaps. The donor site of the dorsal flap was repaired with thick skin grafts, the stumps wound was covered with tongue flap at the shank side of big toe. ResultsVascular crisis occurred in 1 big toe nail composite tissue flap, margin necrosis occurred in 2 dorsalis pedis flap;the other flaps survived, and primary healing of wound was obtained. The grafted skin at dorsal donor site all survived, skin of hallux toe stump had no necrosis. Eight cases were followed up 4-20 months (mean, 15.5 months). All flaps had soft texture and satisfactory appearance;the cutaneous sensory recovery time was 4-7 months (mean, 5 months). At 4 months after operation, the two-point discrimination of the thumb pulp was 8-10 mm (mean, 9 mm), and the two-point discrimination of dorsal skin flap was 7-9 mm (mean, 8.5 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the results were excellent in 4 cases, good in 3 cases, and fair in 1 case. The donor foot had normal function. ConclusionDorsalis pedis flap series-parallel big toe nail composite tissue flap is an ideal way to repair hand skin defect, and reconstructs the thumb, which has many advantages, including simple surgical procedure, no limitation to recipient site, soft texture, satisfactory appearance and function of reconstructing thumb, and small donor foot loss.
