Objective To evaluate the short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus associated with mild to moderate metatarsus adductus. Methods The clinical data of 30 patients (48 feet) who were diagnosised hallux valgus associated with mild to moderate metatarsus adductus and treated by Scarf osteotomy and Akin osteotomy combined with soft tissue procedures between February 2013 and May 2015 were analyzed retrospectively. There were 2 males (2 feet) and 28 females (46 feet) with an average age of 29.4 years (range, 18-50 years). The disease duration was 3-12 years (mean, 6.1 years). The degree of metatarsal adductus was assessed by Sgarlato’s measurement and Yu et al classification criteria, and the degree of metatarsal adductus was mild in 20 feet and moderate in 28 feet. Preoperative X-ray examination showed that the hallux valgus angle (HVA) was (39.4±5.6)°, the first-second intermetatarsal angle (1-2IMA) was (15.2±3.5)°, the metatarsus adductus angle (MAA) was (21.2±3.7)°. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 51.7±10.0, and visual analogue scale (VAS) score was 4.9±2.7 before operation. Postoperative complications and the union time of osteotomies were recorded. At last follow-up, the HVA, 1-2IMA, and MAA were measured on X-ray films, and the AOFAS scores and VAS scores were recorded, then compared them with preoperative ones. Roles - Maudsley score was used to investigate patients’ satisfaction. Results All the incisions healed by first intention. Thirty patients were followed up 24-27 months (mean, 26.4 months). Three patients (4 feet) occured metatarsalgia, and the pain relieved after treated by Custom-Made Orthotics. All the osteotomies were unoin, the healing time was 2-4 months (mean, 2.7 months). At last follow-up, the HVA and the 1-2IMA were (13.2±3.1)° and (5.1±2.3)°, respectively, showing significant differences when compared with preoperative ones (t=14.606, P=0.000; t=22.356, P=0.000); the MAA was (21.0±3.4)° and there was no significant difference when compared with preoperative one (t=0.789, P=0.434). The AOFAS and VAS scores were 91.8±7.5 and 1.1±1.0, respectively, showing signifiant differences when compared with preoperative ones (t=13.787, P=0.000; t=14.781, P=0.000). Satisfaction survey showed that 28 patients were very satisfied and satisfied (93.3%), and 2 cases were not satisfied (6.7%). Conclusion The short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus associated with mild to moderate metatarsus adductus is satisfactory, and no correction is required for metatarsal adductus.
Objective To evaluate the effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus with absorbable screws or metal screws fixation by clinical and radiological data. Methods Between March 2014 and May 2016, the Scarf osteotomy combined with Akin osteotomy was used to treat 62 patients (83 feet) with moderate to severe hallux valgus. Twenty-five patients (35 feet) were fixed by absorbable screws (group A) and 37 patients (48 feet) were fixed by metal screws (group B). The difference in gender, age, affected side, etiology, severity, disease duration, preoperative hallux valgus angle (HVA) and first-second intermetatarsal angle (1-2IMA) measured in weight-bearing anteroposterior X-ray film, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) scores and visual analogue scale (VAS) scores between 2 groups (P>0.05). The complications and healing time of 2 groups were recorded and compared. At last follow-up, the AOFAS and VAS scores, and HVA, 1-2IMA measured by weight-bearing anteroposterior X-ray film were used to evaluate the effectiveness. Results All incisions healed by first intention and no incision-related complication occurred in the two groups after operation. Both groups were followed up, the follow-up time in group A was 12-36 months (mean, 24.4 months) and in group B was 14-38 months (mean, 25.7 months). In group A, 1 foot was complicated with hallux varus, 2 feet had mild stiffness, 1 foot appeared metastatic metatarsal pain, and in group B was 2, 3, 2 feet, respectively. There was no recurrence of hallux valgus in both groups. The difference in the incidence of complications between the two groups after the first operation was not significant (χ2=0.275, P=0.843). The removal rate of internal fixator in group B was 89.2% (33 cases) during the second operation, among which 3 cases had screw slip and 1 case had screw fracture. And 10.8% (4 cases) refused the second removal operation due to their age. Postoperative X-ray films showed that both groups had good healing at the osteotomy site, and there was no significant difference in healing time between the two groups (t=1.633, P=0.285). At last follow-up, the AOFAS score, VAS score, HVA, and 1-2IMA were significantly improved in the two groups when compared with preoperative ones (P<0.05); but no significant difference was found between the two groups (P>0.05). Conclusion The effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus is significant, with few complications. Compared with being fixed by metal screws, being fixed by absorbable screws has the same effectiveness, but can avoid the risk of second operation to remove the internal fixator.
A combined rotational flap was used to repair large scar on the face. The flap was removed from the lateral part of the neck, face and postaural region, between the zygmatic arch and clavicle. The dissection was carried out on the superfic ial of SMAS and platysmus M. Twentysix (12 males and 14 females) were reported. The age ranged from 5 to 28 years. The flap was survived completely in 19 cases. Small area at the margin of the flap was necrotic, which was reducing appeared in the postaural cular region in 6 cases. By reducing the size of the postaural cual component of the flap, necrosis never occured. Among these cases, 11 were followed up for 6 to 14 months. The results were satisfactory. The combined flap was classified as randomized flap because it had no axial and it could be used to cover a large area of skin defect. The color, thickness and quality of the flaps were all close to the normal facial skin. It was considered especially suitable for repair the large wound on the medial twothirds of the cheek.
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.
Objectives To analyze the risk factors of uterine rupture in pregnancy in Chengdu Women’s and Children’s Central Hospital in recent years. Methods The clinical data of pregnant uterine rupture patients who were hospitalized in Chengdu Women’s and Children’s Central Hospital from January 2011 to December 2017 were collected. The risk factors of uterine rupture in pregnancy were analyzed compared with the maternal delivery during the same period. The SPSS 23.0 software was used for statistical analysis. Results A total of 69 patients with uterine rupture were included, involving 14 cases of complete uterine rupture and 55 cases of incomplete uterine rupture. Compared with the pregnant females who were hospitalized during the same period, the incidence of uterine rupture in patients with scar uterus after cesarean section, history of laparoscopic hysterosalping surgery, placental implantation, twins and uterine malformation was higher, and the difference was statistically significant (P<0.05). Among them, the risk of uterine rupture was greater in the interpregnancy interval (IPI)>24 months after cesarean section in patients with scar uterus. There was no significant difference in the incidence of uterine rupture between the elderly and the multiple pregnant females and the maternal delivery during the same period (P>0.05). Conclusions Scar uterus (postoperative cesarean section), history of laparoscopic hysterosalping surgery, placental implantation, twins, and uterine malformation are possible risk factors for uterine rupture in pregnancy. Among them, patients with scar uterus have a greater risk of uterine rupture with IPI>24 months.
Objective To investigate the operative method and efficacy of subcutaneous pedicle scar-band rotation flap in the treatment of cervical postburn scar contracture. Methods Between August 2008 and May 2010, 15 patients with cervical postburn scar contracture were treated with subcutaneous pedicle scar-band rotation flaps, including 9 males and 6 females with an average age of 17.3 years (range, 7-35 years). The disease duration was 1-8 years (mean, 3 years). The locations were the left cervical region in 6 cases, the right cervical region in 8 cases, and mental cervical angle region in 1 case. According to LI Ao’s classification standard for cicartrical contracture, there were 12 cases of grade I and 3 cases of grade II. The area of scar ranged from 8 cm × 5 cm to 25 cm × 12 cm. After scar relaxation, wounds were repaired with the subcutaneous pedicle scar-band rotation flaps of 7 cm × 5 cm to 15 cm × 10 cm at size. In 3 cases of grade II, free split thickness skin grafts (7 cm × 4 cm to 12 cm × 7 cm at size) were used simultaneously. Results After 2 weeks of operation, 2 scar-band flaps had distal partial necrosis and healing was achieved after dressing change with formation of hypertrophic scar; the others survived with healing of incisions by first intention. After 6-12 months of follow-up, all patients possessed good cervical contours, sufficient release of scar contractures, and normal cervico-mandicular or mental cervical angles. The skin’s color and texture were satisfactory. There was no recurrence of cervical scar contracture and other complications. All patients acquired normal cervical movement at last follow-up. Conclusion Subcutaneous pedicle scar-band rotation flap is a simple, efficient, and versatile technique in release of cervical postburn scar contracture. It is an effective method to make use of the lateral excess scar flap to resurface defects caused by scar release.
Objective To explore the method and effectiveness of abdominal expanded subdermal vascular plexus skin flaps in repairing dorsal hand scar. Methods Between May 2005 and October 2010, 16 cases of dorsal hand scars weretreated with the abdominal expanded flaps. There were 13 males and 3 females, aged 22.5 years on average (range, 10-35 years). Defect was caused by burn in 10 cases, hot crush injury in 4 cases, and scald injury in 2 cases. The average scar formation was 21 months (range, 1 year and 6 months to 2 years). The patients had flexion restriction of metacarpophalangeal joint and interphalangeal joint. The scar size ranged from 11 cm × 7 cm to 18 cm × 10 cm. The expander was implanted in abdominal skin and inflated with water regularly at the first stage. After 2 weeks, the expanded pedicled flap was trasferred to repair wounds in which scars were excised. The flap size ranged from 12 cm × 9 cm to 19 cm × 12 cm. After being cut off the pedicle at 14 days, the fingers were divided, and the digital web was formed. The abdominal donor site was directly sutured. Results All flaps survived. The wound and donor site achieved primary heal ing. Sixteen cases were followed up 1 year and 2 months to 3 years with an average of 2 years and 3 months. The flaps had soft texture and good flexibil ity. At last follow-up, hand function was graded as excellent in 13 cases, good in 2 cases, and poor in 1 case with an excellent and good rate of 93.7% according to the total active motion evaluation system. Conclusion Abdominal expanded subdermal vascular plexus skin flap is an effective method to repair large scar of the dorsal hand because it has satisfactory texture, fast rebuilding of blood supply, and large area of survival.
ObjectiveTo study the treatment results of the pre-expanded flaps for scar contracture on face, neck, and joints by comparing with the skin grafts. MethodsA total of 240 cases of scar contracture between July 2004 and June 2014 were included in the study by random sampling; skin grafts were used in 120 cases (skin graft group), and preexpanded flaps in 120 cases (pre-expanded flap group). There was no significant difference in age, sex, injury sites, and disease duration between 2 groups (P>0.05). Re-operation rate and A&F 0-6 quantization score were used to evaluate the treatment results. ResultsThe patients were followed up 12 to 75 months (mean, 23.47 months) in the skin graft group, and 12 to 61 months (mean, 19.62 months) in the pre-expanded flap group. The re-operation rate of the skin graft group was 72.5% (87/120), and was significantly higher than that of the pre-expanded flap group (19.2%, 23/120) (P=0.000). The re-operation rate of the neck contracture in teenagers was the highest. It was 93.9% in the skin graft group and 35.0% in the pre-expanded flap group. In the patients who did not undergo re-operations, A&F 0-6 quantization score of the skin graft group was 2.85±1.12, and was significantly lower than that of the pre-expanded flap group (5.22±0.74) (t=13.830, P=0.000). ConclusionPre-expanded flap for scar contracture on face, neck, and joints has lower re-operation rate and better aesthetic and functional restoration than skin graft. It should be regarded as the preferred method for teenagers.
ObjectiveTo evaluate the effectiveness of different flaps for repair of severe palm scar contracture deformity. MethodsBetween February 2013 and March 2015, thirteen cases of severe palm scar contracture deformity were included in the retrospective review. There were 10 males and 3 females, aged from 14 to 54 years (mean, 39 years). The causes included burn in 9 cases, hot-crush injury in 2 cases, chemical burn in 1 case, and electric burn in 1 case. The disease duration was 6 months to 6 years (mean, 2.3 years). After excising scar, releasing contracture and interrupting adherent muscle and tendon, the soft tissues and skin defects ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. The radial artery retrograde island flap was used in 2 cases, the pedicled abdominal flaps in 4 cases, the thoracodorsal artery perforator flap in 2 cases, the anterolateral thigh flap in 1 case, and the scapular free flap in 4 cases. The size of flap ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. ResultsAll flaps survived well. Venous thrombosis of the pedicled abdominal flaps occurred in 1 case, which was cured after dressing change, and healing by first intention was obtained in the others. The mean follow-up time was 8 months (range, 6-14 months). Eight cases underwent operation for 1-3 times to make the flap thinner. At last follow-up, the flaps had good color, and the results of appearance and function were satisfactory. ConclusionSevere palm scar contracture deformity can be effectively repaired by proper application of different flaps.
Objective To investigate the surgical procedures and outcomes of repairing the wound in the posterior wall of vaginal orifice by labium minus flap transfer, when vagina tightening plastic surgery is performed on the patient with scar in the posterior wall of vaginal orifice and labium minus hypertrophy. Methods From May 2007 to May 2008, 10 patients suffering from postpartum vaginal relaxation combined with scar in the posterior wall of vaginal orifice and labium minus hypertrophy were treated. The patients aged 28-40 years old and the width of their labium minus was 3-5 cm. Six ofthem had coitus pain. Vaginal tightening surgery was performed, meanwhile the hypertrophic labium minus was preparedinto the anterior-pedicle labium minus flap (4 cm × 1 cm-5 cm × 1 cm) and the posterior-pedicle labium minus flap (3 cm × 2 cm-4 cm × 3 cm), respectively. The posterior-pedicle labium minus flap was transferred inwards by 90° to repair the wound caused by the resection of the scar, and the anterior-pedicle labium minus flap was sutured in situ to form the new labium minus. Results All the posterior-pedicle labium minus flaps survived, except for 3 cases in which the epidermis 1 cm around the distal end of posterior-pedicle labium minus flap was exfol iated and recovered 2 weeks after hi p bath with potassium permanganate solution (1: 5 000). All the anterior-pedicle labium minus flaps survived, and all the incisions healed by first intention. Over the follow-up period of 2-8 months, all the patients were satisfied with their vulva configuration, good elasticity of vaginal orifice and no tenderness pain of vaginal orifice. The sensitivities to feel ing, such as touch and pain, of the transferred labium minus flap were similar to the normal labium minus. Postoperatively, the coitus pain disappeared, 7 cases had much better sex l ife and 3 cases had no significant improvement in sex l ife. Conclusion Transferring labium minus flap to vaginal orifice is an effective way to improve the coital pain resulted from the scar of vaginal orifice.
