Objective:Medial sural artery perforator flap (MSAPF) was applied to aesthetically reconstruct wounds in foot, and clinical outcome of this surgical method was explored.Methods:A retrospective analysis was conducted on the data of 10 patients who underwent the surgery of transfer of free MSAPF in reconstruction of foot wounds in the Department of Foot and Ankle Surgery, Xuzhou Renci Hospital from January 2020 to January 2023. The patients were 6 males and 4 females, aged 21 to 52 years, with an average of 42.5 years. The soft tissue defects of the injuries were at 2.0 cm × 4.0 cm to 3.5 cm × 6.0 cm in size, with deep tissues exposure down to the base of wound. MSAPF was used for aesthetic reconstruction of the wounds. The surgical procedures were: (1) The flap was thinned under a microscope and only the subdermal vascular network was kept. (2) Vascular pedicle of the flap was taken as long as possible and had it anastomosed with the proximal dorsal foot artery and vein through a subcutaneous tunnel. (3) Allg?wer-Donati method was applied to suture the skin of flap. (4) Donor site was directly closed in surgery. All patients were entered in the scheduled postoperative follow-up at the outpatient clinic of the surgeon who performed the surgery to evaluate the postoperative effect and observe the survival of flaps. Maryland foot function score and British Medical Research Council (BMRC) sensory function score were used to assess the recovery of flap and limb function.Results:The flaps completely survived, and all the donor and recipient sites had primary healing. All of the 10 patients were included in the postoperative follow-up which lasted 8 to 15 months, with an average of 12 months. The flaps from foot featured a pleasing appearance, with good elasticity and wear-resistant. All patients were satisfied and able to walk normally and bear weight without an occurrence of flap ulceration. At the final follow-up, the therapeutic effect was evaluated according to the Maryland scoring system and achieved the scores at 91 to 98, with 95.6 in average. Nine patients were rated as excellent and 1 as good. The sensory grading by BMRC for the flaps was as follows: the flap sensation of the sutured nerve group recovered to S 3 in 3 cases and S 4 in 2 cases, while the non sutured nerve group only recovered protective sensation, S 2 in 3 cases and S 2+ in 2 cases. Conclusion:By applying MSAPF aesthetics to treat foot wounds, a good appearance has been achieved, with good functional recovery and satisfactory therapeutic effects.

【Objective】 To investigate the efficacy of the adjustable "paper clip" techniques in the suture of dorsal vein complex (DVC) and retention of urethral function in robot-assisted laparoscopic radical prostatectomy (RALRP). 【Methods】 A total of 30 cases of prostate cancer treated with RALRP were enrolled, all of which used the adjustable "paper clip" techniques. During operation, the DVC was sewed with barbed suture, and then a reverse suture was made through two sides of the prostatic ligaments. A Hem-o-lock was used to fasten the suture, which would be flexible to control the degree of tightness for the ligature. Perioperative and follow-up data of urinary continence and symptoms were collected and analyzed. 【Results】 All operations were successful. The estimated blood loss was (123.3±80.7) mL, 53.6% patients recovered continence in 1 month, and the continence rate increased to 92.9% and 96.3% at month 3 and 6. 92.9 of patients had no risk of incontinence 3 months after surgery. 【Conclusion】 The adjustable "paper clip" techniques have advantages in reducing blood loss, maintaining clear surgical field, preserving urethral function, and improving urinary continence.

Objective: To understand the neglect status among preschool non-only-child in Nantong, and to provide theoretical basis for the prevention and intervention of non-only child neglect. Methods: Using the method of random cluster sampling, a total of 1 141 parents of children from 9 kindergartens in the main urban area of Nantong were investigated with National Neglect Norm Scale for Children aged 3 to 6 years. Results: The neglect rate of preschool children in Nantong City was 28.6%, with neglect score being (40.21±6.67). The neglect rate of non-only-child was 32.6%, with neglect score being (41.14±6.73). The total and physical neglect rate of non-only-child were higher than that of only child, and the total neglect score and physical, emotional, educational, safety, medical neglect dimensional scores were higher than that of only-child, the difference were all statistically significant ( χ 2/ t = 6.21, 17.57; 3.95, 4.98, 3.45, 2.70, 2.01, 3.11, P <0.05). In non-only-child, univariate analysis showed that there were no significant differences in neglect rate and scores among children by gender and family types ( P >0.05); There was no significant difference in the child neglect rate between different age groups and children in different families ( χ 2 =3.59, 2.99, P >0.05), but there was a statistically significant difference in the degree of neglect ( t=2.79, 3.04, P <0.05). The neglect rate and score of non-only-child with high level of family income, parental education and parental relationship was relatively low, while the neglect rate and score in non-only-child whose grandparents serving as primary caregiver were higher ( P <0.05). Multivariate Logistic regression analysis showed that family monthly income less than 5 000 yuan was associated with 2.73 times higher risk of neglect compared to children with family monthly income more than 12 000 yuan. The risk of neglect among children whose grandparents serving as caregivers was associated with 2.17 times higher than children with parental care. The risk of neglect of children with poor parental relationship was 2.29 times higher than that of children with good parental relationship ( P <0.05). Conclusion The neglect among preschool non-only-child in Nantong City is common. Improvement in family economic status, parental care and parent relationship might help reduce neglect among preschool non-only-child.

Objective:To investigate the efficacy of TiRobot navigation combined with ankle arthroscopy in the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture.Methods:From January 2019 to September 2020, a total of 13 patients with Hawkins type Ⅱ talus neck fracture were admitted to Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. They were 8 males and 5 females, with a mean age of 35.8 years (from 22 to 61 years). All fractures were reduced and fixated using TiRobot navigation combined with ankle arthroscopy. Time for fracture reduction assisted by intraoperative arthroscopy, time for internal fixation assisted by TiRobotic navigation, fracture union time and complications were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used at the last follow-up to evaluate the functional outcomes.Results:All the operations were finished within 2 hour. The primary screw placement succeeded in all. The time for fracture reduction assisted by intraoperative arthroscopy averaged 52.8 min (from 43 to 66 min) and the time for internal fixation assisted by TiRobotic navigation 43.6 min (from 33 to 55 min). All the patients were followed up for an average 13.3 months(from 12 to 15 monhs). They obtained bony union within 3 months. One patient developed traumatic subtalar arthritis with mild pain and was treated conservatively. None of the patients had complications like incision infection or talus necrosis. The average AOFAS ankle-hindfoot score was 91.0 points (from 83 to 94 points) at the last follow-up.Conclusion:In the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture, TiRobot navigation combined with ankle arthroscopy shows advantages of minimal invasion, accurate reduction and screw placement, and limited complications, leading to fine short-term functional outcomes.

Objective:To summarise the experience in use of sural neurouascular flap in repair of the soft tissue defects of foot and ankle, and explore the methods in promoting the survival and appearance of the flap.Methods:Data of 10 patients who underwent sural neurocutaneous flap surgery for repairing soft tissue defects in the foot and ankle in the Department of Foot and Ankle of Xuzhou Renci Hospital from October 2019 to June 2020 were retrospectively analysed. Among the 10 patients, 8 were males and 2 were females, and the age ranged from 18 to 54 years old, with an average age of 42.5 years old; Causes of injury: 8 patients injured by traffic accident and 2 by incision necrosis after calcaneal fracture operation. The areas of soft tissue defect were 4.0 cm×6.0 cm-16.0 cm×10.0 cm. Sural neurouascular flap was used for the defect repairs. Method of optimisation: ①The small saphenous vein in the flap was separated and retained in the limb to optimise the venous circulation. ②Freed peroneal perforator vessels that entered the pedicle, and made the point where the vessels entering the pedicle as the rotation point. The pedicle contained the sural neurovascular bundle, the main trunk of the small saphenous vein and the fascia tissue, with a width about 2.0 cm. It not only increased the blood supply of the flaps, but also a good appearance of the pedicle. ③ The torsion of the pedicle was covered by an arc-shaped flap and transferred through an open channel to prevent compression. ④The donor site was covered with relay flap. According to the location of the donor site, a proximal peroneal artery perforator flap or medial and lateral sural artery perforator flap was selected. ⑤Sural nerve was anastomosed with the peripheral sensory nerve in some cases. The survival of the flap, Maryland Foot Function Score and British Medical Research Council (BMRC) sensory function evaluation were investigated in the follow-up to evaluate the functional recovery of the flap and limb.Results:All the 10 patients received the follow-up for 6 to 12 months, with an average of 8.5 months. The donor and recipient flaps survived completely with good appearance in lower limb, good soft texture, good elasticity and wear resistance. The sensation of the flap with nerve anastomosis in 3 cases was evaluated according to BMRC, and they achieved sensation recovery up to level of S 3 or above. The patients had great satisfactions. At the last follow-up, the curative efficacy was evaluated according to the Maryland scoring system. It ranged from 85 to 98 points, with an average of 91.6 point, 8 patients in excellent and 2 in good. Conclusion:Sural neurouascular flap can achieve a sufficient blood supply, a reasonable venous circulation and a high survival rate. The donor site was covered with relay flap to obtain a good appearance, and the anastomosed sensory nerve offered a good sensation. The function of foot and ankle recovered well, and the clinical effect was satisfactory.

Objective:To investigate the clinical efficacy of a new 3D printed guide plate in the minimally invasive treatment of fresh closed Achilles tendon rupture.Methods:From January 2019 to January 2020, 14 fresh closed Achilles tendon ruptures were treated by minimally invasive surgery at Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. There were 13 males and one female, with an average age of 39.1 years (from 18 to 63 years). The rupture of the Achilles tendon body, 3 cm in length on average, was located 2 to 6 cm above the attachment of the calcaneal tuberosity. The ruptured Achilles tendon was repaired by suture with the aid of the new 3D printed guide plate. After operation, in cooperation of the Rehabilitation Department, we performed rehabilitation exercise under the guidance of the concept of Enhanced Recovery After Surgery (ERAS). The length of incision, operation time, intraoperative blood loss, ankle function at the last follow-up and follow-up complications were recorded.Results:In this cohort, incision length averaged 2.5 cm (from 2.0 to 3.5 cm), operation time 45 min (from 30 to 60 min), and intraoperative blood loss 15 mL (from 10 to 20 mL). The 14 patients were followed up for 13 to 16 months (average, 14 months) after operation. In one patient, the epidermis at the incision edge became black and necrotic, which was healed after dressing change. Follow-ups observed no such complications as suture rejection, sural nerve injury, or Achilles tendon re-rupture. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores at the last follow-up averaged 98 points (from 93 to 99 points), yielding 13 excellent cases and one good case; according to the Arner-Lindholm evaluation, the efficacy was excellent in 12 cases, good in one and poor in one.Conclusion:The minimally invasive treatment of fresh closed Achilles tendon rupture with our new 3D printed guide plate has exhibited advantages of minimally invasive incision, limited complications, simple manipulation, good functional recovery of the ankle joint and strong reproducibility of surgical operations.

Objective To observe the effect of perioperative rehabilitation on anterior spinal cord syndrome caused by cervical hyper-flexion injury. Methods Sixty-nine inpatients with anterior spinal cord syndrome after cervical hyperflexion injury from January, 2012 to De-cember, 2014 were reviewed. 32 cases (group A) accepted systematic rehabilitations and other 37 cases (group B) did not. They were as-sessed with Japanese Orthopaedic Association (JOA) scores preoperatively and 1-year follow-up. Results All the patients succeeded in the operation. The JOA score improved more 1 year follow-up in group A than group B (t=2.538, P=0.044). Conclusion Systematic rehabilita-tion may work in the management of anterior spinal cord syndrome after cervical hyperflexion injury.

Objective To study the mechanism, pathology, diagnosis and manage strategy of cervical fracture dislocation combined with anterior spinal cord syndrome (ASCS). Methods 32 cases of cervical fracture dislocation combined with ASCS from January 2012 to September 2014 were summarized. The mechanisms of injury and pathological characteristics were analyzed. All of them received surgical treatment. Anterior approach or anterior approach combined with posterior approach was chosen according to the characteristics of injury. Results All surgical treatments were successfully performed. There were 22 cases (68.75%) with hyperflexion, 5 cases (15.62%) with vertical hit, 1 case (3.12%) with hyperextension and 4 cases (12.5%) with multiple reasons. There were 4 cases (12.5%) with simple anterior dislocation, 28 cases (87.5%) with fracture combined with anterior dislocation. Only 8 cases were successfully diagnosed as ASCS, and the others (24 cases) were generally defined as spinal cord injury. Conclusion ASCS is not so rare. Hyperflexion injury is the most common mechanism. Anterior dislocation and fracture combined with anterior dislocation are the general types of pathology. Conscientious physical examination with CT and MRI can facilitate the diagnosis. Anterior approach or combined with posterior approach could be selected according to injury mechanism.

Objective To investigate the effect of comprehensive rehabilitation direction on functional ankle instability (FAI). Methods 32 consecutive patients with FAI were divided into 2 groups. The rehabilitation group (n=16) finished their rehabilitation program under the instruction of physiotherapists in the hospital, and the control group (n=16) exercised at home by written instruction. All the patients were tested with One Leg Standing Test (OLST) and Foot and Ankle Disability Index (FADI) for the injured ankle before and 4 weeks after training.Results The scores of both OLST and FADI improved after training in the rehabilitation group (P<0.01), but did not in the control group (P>0.05); and improved more in the rehabilitation group than in the control group (P<0.05). Conclusion The comprehensive rehabilitation direction is effctive on FAI.
