Objective To investigate the therapeutic effects of the groin skin and iliac bone composite graft on the repair of severe contracture of the first web space and one-stage reconstruction of the pollicis opponens function under the condition of no ideal muscle or tendon used. Methods From July 2003 to February 2006, 5 patients (4 males, 1 females; age range, 2038 years) with severe contracture of the first web space with loss of the pollicis opponens function were treated by the groin skin and iliac bone composite graft, with the clinical observation performed. The defect was caused by a crush injury in 3 patients, by an explosion injury in 1 patient, and by awrist joint mutilation injury in 1 patient. They all had been treated by operation at least once with a disease course of 6-24 months. The width and the angle of the first web space was 18 mm and 20° on average. Results The followed-up for 612 moths revealed that all the flaps had a success. The pedicle of the groin skin and iliac bone composite graft was cut off after 3 weeks, and 8 weeks later there was a bone union between the imbedded bone block and the first and second metacarpal bones. There was no evidence that the imbedded bone block was deformed or absorbed. The width of the first web space was augmented by an average of 32 mm, the angle of the first web space was augmented by an average of 60°. The pollicis opponens function recovered. Conclusion It is relatively simple and reliable to repair the contracture of the first web space and reconstruct the pollicis opponens function in one-stage usingthe groin skin and iliac bone composite graft.
Objective To investigate the effectiveness of groin flap combined with medial plantar artery perforator flap (MPAP) for degree Ⅲ-Ⅳ defects of multiple fingers. Methods Between January 2018 and June 2019, 12 patients with degree Ⅲ-Ⅳ defects of multiple fingers caused by crushing were admitted. There were 9 males and 3 females with a median age of 29 years (range, 16-42 years). The mean interval between the injury and admission was 3 hours (range, 1-9 hours). The injured fingers of 7 cases were index and middle fingers, 4 cases were middle and ring fingers, and 1 case was index, middle, and ring fingers. All fingers were taken thorough debridement and covered by the vacuum sealing drainage device during the emergency operation. The mean interval between the debridement and flap repairing was 18 hours (range, 12-36 hours). During the first-stage operation, the iliac bone graft was used to reconstruct bone frame, and the proximal interphalangeal (PIP) joint from the foot was transferred as the digital PIP joint, then the thin groin flap and MPAP were tailored to cover the dorsal and palmar defects, respectively. The size of the groin flap was 7.0 cm×4.5 cm-14.0 cm×9.0 cm, and the size of the MPAP was 8.0 cm×4.5 cm-14.0 cm×6.5 cm. The abdominal donor site was directly sutured, and the foot was repaired with full-thickness skin grafting. The flaps were separated into the finger shape at the second-stage. Results All the flaps survived, and the wounds healed by first intention; the incisions in the donor site healed by first intention, and the skin grafts survived completely. All patients were followed up 12-18 months (mean, 16 months). At last follow-up, the injured finger was similar to the contralateral one in terms of texture, appearance, and color. The mean two-point discrimination was 8 mm (range, 6-10 mm), and the sensate level recovered to the S3-S4. According to the Michigan Hand Outcomes Questionnaire (MHQ), the reconstructed hand function was excellent in 8 cases and good in 4 cases. There was no complication in the donor sites. Conclusion The degree Ⅲ-Ⅳ defects of multiple fingers were repaired by the groin flap and MPAP, and the reconstructed fingers can perform good texture and motion with being sensate, with less sacrifice on the foot.
Objective To investigate an operative method of repairing large skin defect of the forearm and the hand. Methods From July 2003 to September 2008, 11 patients with large skin defect of the forearm and the hand were repaired using bilateral groin flaps in complex with abdominal flaps, including 7 males and 4 females aged 17-55 years old (average33.5 years old). Among the 11 cases, 5 were caused by carding machine and 4 by traffic accident, and the interval between injury and operation was 90 minutes to 6 hours (average 3.5 hours); 2 cases suffered from severe cicatricial contracture deformity in the late stage of burn injury, and the interval between injury and operation was 7 months and 19 months, respectively. The size of skin defect ranged from 42 cm × 12 cm to 60 cm × 16 cm. The flaps harvested during operation was 45.0 cm × 10.5 cm - 62.0 cm × 18.0 cm in size. Pedicle division of the combined flaps was performed 4 weeks after operation. The donor site wound was repaired by direct suturing in 7 cases and by free skin grafting in 4 cases. Results All flaps survived. All incisions healed by first intention. The donor site wound all healed by first intention. Skin graft all survived. All patients were followed up for 2 months to 3 years. The flaps were soft in texture, full in contour, and normal in color. Sensory recovery of the flaps was evaluated according to the Criteria of UK Medical Research Council (1954), 4 cases were in grade S1, 6 in grade S2, and 1 in grade S3. Hand function was assessed by the Criteria of Chinese Hand Surgery Society, 7 cases were graded as excellent, 2 as good, 2 as poor, and the excellent and good rate was 81.8%. Conclusion Combined use of bilateral groin flaps and abdominal flap is an effective approach to repair large skin defect of the forearm and the hand due to its simple operative procedure and satisfying effect.
Objective To investigate the effectiveness of groin flap with external oblique aponeurosis in repair of tendon and skin defects of dorsal foot. Methods Between October 2016 and January 2020, 12 patients with compound tissue defects of the dorsal foot caused by trauma were treated. There were 9 males and 3 females, with a median age of 42 years (range, 32-65 years). The size of the skin defects ranged from 8 cm×5 cm to 12 cm×8 cm. All wounds were accompanied by extensor tendon injury, including 6 cases of extensor hallucis longus tendon defect, 5 cases of extensor digitalis longus tendon defect, and 3 cases of extensor digitalis longus tendon and extensor digitorum brevis defects. The interval between injury and admission was 1-6 hours (mean, 3 hours). After admission, the wounds were thoroughly debrided, and the groin flap with external oblique aponeurosis was used to repair the skin and tendon defects in the second stage. The size of skin flap ranged from 10 cm×6 cm to 13 cm×9 cm, and the size of the external oblique aponeurosis ranged from 5.5 cm×3.0 cm to 8.0 cm×5.0 cm. The wounds at donor sties were sutured directly. Results All flaps survived completely without significant complications. All incisions of the recipient and donor sites healed by first intention. All patients were followed up 16-24 months (mean, 18 months). The flaps were satisfactory in appearance and soft in texture. At last follow-up, 9 cases were excellent and 3 cases were good according to the American Orthopaedic Foot and Ankle Society (AOFAS) metatarsophalangeal-interphalangeal joint scale criteria. The toe function was satisfactory. The line scar was left without hernia or other morbidity on the donor site. Conclusion The groin flap with the external oblique aponeurosis can repair the tendon and skin defects of the dorsal foot, with concealed donor site, easy dissection and adjustable thinness, as well as the enough tough aponeurosis.
From jan.1984 through dec.1991,65 cases of hand skin defects were primarily repaired by podicled groin flap. Four of the 65 cases had skin defects on both sides of the palms and dorsal aspot of the hands which were treated by the Y-shaped hypogastric groin flap .Five easec had thumb loss in which the lxdicled groin tubed flap was used to reconstruct the thumb.The time of division of the pedicles ranged from 14 to 28 days(averaged 16 days).All flape survived after division of the podicl...
Objective To investigate the application of multi-detector row spiral CT （MDCT） and multi-planer reconstruction （MPR） in identify the anatomy detail of normal adult groin region. Methods We retrospectively collected the CT images of 50 adult subjects with normal groin anatomic structure underwent groin region thin-slice MDCT scans between July and December 2009, 30 males and 20 females, obtained the coronal and sagittal views by MPR, investigated the value of different plans in identifying anatomic detail. Results Bilateral inferior epigastric artery (100/100, 100%), spermatic cord (60/60, 100%), and round ligament of uterus (40/40, 100%) were well identified on all plans in all subjects. The bilateral “radiological femoral triangle” could be demonstrated on coronal views in all subjects (100/100, 100%). The bilateral inguinal ligament were visible on coronal view in all subjects (100/100, 100%) and on sagittal views in 34 subjects (68/100, 68%), but on axial views was identified in 3 male subjects (6/100, 6%). The bilateral inguinal canal and deep inguinal ring were reliably visible on coronal views in all subjects (100/100, 100%), and on sagittal views in 46 subjects (92/100, 92%). On coronal views, the widths of inguinal canal was (0.97±0.35) cm in left, (0.89±0.23) cm in right for males, and (0.62±0.11) cm in left, (0.71±0.11) cm in right for females. No significant difference was found between two sides (P=0.059 in males， P=0.067 in females), but there were significant differences between males and females (P=0.007 in left， P=0.009 in right). Transverse diameter of deep inguinal ring was (1.32±0.31) cm in left, (1.31±0.36) cm in right for males, and (1.07±0.35) cm in left, (1.07±0.30) cm in right for females. No significant difference was found between two sides (P=0.344 in males， P=0.638 in females), but there were significant differences between males and females (P=0.001 in left， P=0.002 in right). Conclusion MDCT with different plans plays an important role in identify the anatomic details of groin region, the coronal views especially.
ObjectiveTo compare the clinical efficacy of abdominal preperitoneal laparoscopic hernia repair with 3DMax patch and plain film for treatment of inguinal hernia. MethodsThe clinical and follow-up survey data of 120 patients with inguinal hernia in The Second Affiliated Hospital of Harbin Medical University, between January 2009 and May 2014, which were treated by laparoscopic transabdominal preperitoneal repair (TAPP) were retrospectively analyzed. One hundred and twenty cases were divided into two groups:plain film group (45 cases) and 3DMax group (75 cases) according to the intraoperative use of different patchs. The patches of 3DMax group were not fixed, the patches of plain film group were fixed with metal nails. The postoperative clinical effect of two groups were analyzed. ResultsThe operative time, intraoperative blood loss, and postoperative hospitalization days of two groups were no statistical significance (P > 0.05). The postoperative off bed activity time of patients in 3DMax group and plain film group was (20.2±8.1) h and (26.3±9.2) h, respectively, the average off bed activity time in 3DMax group was significantly earlier than that in plain film group (P=0.041). The material expenses and hospitalization expenses of the 3DMax group were significantly lower than those of the plain film group (P=0.001, P=0.038). The incidence of foreign body sensation of inguinal region in 1, 3, and 9 months after operation of 3DMax group were lower than those of plain film group (P=0.045). The VAS score in 1 and 3 months after operation of 3DMax group were lower than those of plain film group (P < 0.05), but there was no statistically significant in 6 months after operation of 2 groups (P > 0.05). There was no recurrence case in two groups. ConclusionsThe use of 3DMax patch in laparoscopic TAPP operation have more simple operation, hospitalization expenses decreased, recovery faster, postoperative inguinal nerve pain and foreign body sensation more lighter, and complications more less. It is worthy of clinical popularization and Application.
