Transradial approach is the classical access for coronary angiography and percutaneous coronary intervention (PCI). With the increase in the number of interventional procedures, some disadvantages of the transradial approach have also been found, it is easy to lead to various complications, such as radial artery occlusion, radial nerve injury, and puncture difficulties after radial artery spasm. Therefore, some experts put forward the approach of distal radial artery approach for interventional therapy, which has the advantages of convenient positioning, easy postoperative hemostasis, less damage to the proximal radial artery and improving patients' comfort. However, there is no special distal radial artery hemostat in clinic, which limits the development of this approach to a certain extent. Therefore, based on the principles of anatomy and physics, cardiovascular physician at Jiading District District Central Hospital in Shanghai designed and invented a distal radial artery hemostatic device, which is convenient for clinical hemostasis of distal radial artery puncture, and obtained the National Utility Model Patent (patent number: ZL 2021 2 2097829.6). The hemostatic device consists of a glove body with a silicone gasket protruding towards the skin on the inner surface and a binding component. The patient's hand is inserted into the glove body, and after being fixed by the restraint component, the silicone gasket can effectively compress the location of the radial artery puncture point, and play a good hemostatic effect with less pressure, avoid the common complications of proximal radial artery hemostatic, and reduce the discomfort of the patient. Has good application value.

Objective:To investigate the clinical efficacy of reconstruction with the hallux tissue flap for the fingertip defects of thumb and fingers based on the concept and technique of full reconstruction.Methods:From September 2022 to February 2023, the patients with thumb and fingertip defects who were reconstructed using the concept and technology of full reconstruction in Xuzhou Renci Hospital were respective analysised. Based on the degree of defect in the nail bed, bone, and soft tissue of the hand, a hallux osteo-onychocutaneous flap or hallux nail flap was designed and harvested from the same side of the toe, and free transplantation was performed to reconstruct the damaged fingertip. The wounds in the donor site that could not be sutured primarily were treated with dressing change. The surgical complications, the appearance of the reconstructed finger and donor site, Semmes-Weinstein monofilament (SWM) examination, 2-point discrimination (2PD) measurement, and patient satisfaction were regularly recorded. According to the functional evaluation criteria for thumb and finger reconstruction issued by the Hand Surgery of the Chinese Medical Association, the function of the reconstructed fingers was evaluated as excellent (13-15 points), good (9-12 points), fair (5-8 points), and poor (≤4 points). The patients were investigated whether they were satisfied with the outcomes.Results:A total of 8 patients (9 fingers) including 5 males and 3 females were enrolled. The average age was 32.4 years (range, 22-46 years). There were 1 thumb, 2 index fingers, 5 middle fingers, and 1 ring finger. 7 cases (8 fingers) were repaired with the hallux osteo-onychocutaneous flap, and 1 case (1 finger) was repaired with the hallux nail flap. All the reconstructed fingers survived uneventfully, and the recipient site healed primarily, and the donor site healed after dressing change, without infection and other complications. All the 8 patients (9 fingers) were followed up for 3-7 months. The nail plate of the donor site naturally grew and recovered nearly normal. Depression formation was observed at part of the deck junction of the recipient site, and scars were left in the pulp and fibular side of the hallux. At the final follow-up, the reconstructed fingers recovered protective sensation and tactile sense, and the 2PD of the reconstructed fingers was 9 mm and 10 mm in two cases. The SWM score was 3.60-4.31, mean 3.96. The results were the monofilament specifications and indicating the protective sensation was diminished. Functional evaluation of reconstructed fingers: 9 fingers in 8 cases scored 13-14 points, all reaching an excellent level. All patients were satisfied with the surgical results.Conclusion:Based on the concept and technology of full reconstruction, the fingertip defects of the thumb and finger can recover close to normal with the hallux tissue flap in the short-term, while ensuring the overall shape and function of the hallux donor area, achieving a balance between the donor and recipient areas, and achieving satisfactory clinical results.

Objective:To investigate the therapeutic efficiency of various types of Flow-through flap in the reconstruction of soft tissue defect with defect of proper palmar digital artery.Methods:Retrospective analysis was carried out on 22 patients who were treated with perforator flap of posterior interosseous artery, venous flap, the superficial palmar branch of radial artery flap, and "C" shaped flap of the great toe for soft tissue defects of hands with defects of palmar proper digital artery in the Department of Hand Surgery of Xuzhou Renci Hospital from January 2019 to January 2023. The patients were 15 males and 7 females with an average age of 39.5 (21-61) years old. The injured digits were 1 thumb, 6 index fingers, 8 middle fingers, 5 ring fingers and 2 little fingers. Ten injuries were of left hand and 12 of right hand. The wound size was 1.5 cm × 1.5 cm-4.5 cm × 3.0 cm, and the flap size was 2.0 cm × 1.5 cm-5.0 cm × 4.0 cm. The donor site wound were directly sutured and closed or treated by dressing changes to heal. Postoperative follow-ups were arranged at 1, 2, 3, 6 and 12 months after surgery at outpatient clinic, through telephone or WeChat interviews. The flap survival, postoperative complications at donor and recipient sites, patient satisfaction and range of motion of interphalangeal joint were observed and recorded.Results:Twenty flaps survived uneventfully. Tension vesicles appeared on the 2 arterialised venous flaps and healed after dressing changes. All donor sites healed uneventfully. All patients were included in the postoperative follow-up for an average of 10.3 (6-24) months. Appearance of the perforator flaps of posterior interosseous artery was bloated and the movement of interphalangeal joint was limited in 1 digit, however the patient refused a further flap thinning surgery. Scar dissection was performed on 1 of the venous flaps in stage II surgery. The rest of 20 patients were satisfied with the appearance of flaps hence no further thinning surgery was performed. According to Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 12 cases were evaluated as excellent, 9 cases as good, and 1 case as poor at the last follow-up. The mean static TPD was found at 6.9 (5-11) mm, and the average Semmes-Weinstein monofilament (SWM) test was found at 4.47 (3.61-6.65).Conclusion:The 4 types of perforator flap can be employed in the reconstruction of digital defect with defect of palmar proper digital artery in a one-stage surgery with satisfactory outcomes. Surgeons can accordingly make individualised surgical plans as required for the patients.

Objective:To investigate the therapeutic efficiency of multiple forms of microdissected perforator flaps in the reconstruction of limb defect.Methods:The data of patients treated in the Department of Hand Surgery of Xuzhou Renci Hospital from June 2020 to June 2022 for repairing wound of hands, feet, limbs and popliteal fosses with microdissected perforator flap were retrospectively analyzed. CT angiography and color Doppler ultrasound were performed in all patients before surgery to locate perforator vessels, design the donor flap, and cut the flap retrograde according to the design line. After confirming good blood supple, the flap was harvested under the microscope, and fat particles were cut around the vascular pedicle by "insect eating" technique. After that, the flap was transferred to the recipient area, completed the vascular anastomosis, and placed the drainage tube. The donor site was closed directly. The blood circulation of the flap was observed closely after operation. Regular follow-up visits were conducted in outpatient clinics, door-to-door visits and WeChat to record sensory recovery and complications. Postoperative wound healing, flap shape, flap sensation, flap temperature and scar in donor area were evaluated using the efficacy satisfaction scale, which was divided into four grades: excellent (2 points), good (1 point), fair (0 point) and poor (-1 point). The total score of 5-10 was satisfactory, 0-4 was average, and -1--5 was unsatisfactory.Results:A total of 16 patients were included, including 8 males and 8 females. The age ranged from 26 to 65 years, with an average age of 45.9 years. There were 2 cases of upper limb soft tissue defect, 2 cases of hand degloving injury, 11 cases of hand skin soft tissue defect, and 1 case of popliteal soft tissue defect. The wound size ranged from 3.0 cm×4.5 cm to 13.0 cm×30.0 cm. Free medial sural artery perforator flap was used in 4 cases, interosseous dorsal artery perforator flap in 1 case, anterolateral femoral perforator flap in 6 cases, thoracic umbilical flap in 1 case, anterolateral femoral perforator flap combined with superficial circumflex iliac artery perforator flap in 1 case, and superficial circumflex iliac artery perforator flap in 3 cases. The size of the skin flap was 3.5 cm×5.0 cm - 9.5 cm×30.0 cm. After operation, 15 cases of flaps successfully survived, 1 case of venous crisis occurred 1 day after operation, and successfully survived after exploration and re-anastomosis of blood vessels. The wounds in the donor area healed in one stage without wound infection, delayed healing and other complications. All patients were follow-up for 7 to 18 months (mean 12.1 months), the skin flap survived well, no pigmentation, bloated appearance, and no patients requested secondary thinning treatment. The skin flap sensation recovered light touch in 1 case, protective sense in 9 cases and deep touch only in 6 cases. No significant thickening of skin flap was observed in the later period of follow-up, and skin flap wear was observed in 1 patient. There were only linear scars left in the donor area, and there were no obvious abnormalities in appearance and function. Efficacy satisfaction evaluation showed that all patients were satisfied with the therapeutic effect, scoring 6-9 points, with an average of 7.8 points.Conclusion:Microdissected perforator flap technique provides a one-stage surgical solution for aesthetic and functional areas with high requirements, and satisfactory clinical efficiencies can be obtained.

The homogeneous management of outpatient services at public hospitals with multi-campus is the foundation for promoting high-quality development of hospitals. Since 2013, a large general hospital had implemented a practice of multi-campus homogeneous management of outpatient services based on the hospital′s integrated organizational structure and management system, addressing such issues as weak outpatient service capabilities in the early stages of new campus construction, lack of homogenization in management system implementation, and poor communication between cross hospital services and information. An integrated post management mode was established with multi-post service integration, cross-post personnel flow and unified job standard. An integrated outpatient quality management system was created by the strategy of " one standard" system management, " one platform" service handling, integrated quality monitoring and management, and multi-aspect service experience improvement. The integration of vertical management and flat management were promoted through the committee system, three-level management system, and functional groups. At the same time, this management practice actively leveraged the advantages of the hospital to innovate services, and promoted the interconnection of outpatient service information across hospital areas, to integrate outpatient service positions, work, services, and management across multi campuses. The satisfaction rate of outpatient patients, the pass rate of outpatient medical records, and the on-time visit rate of outpatient physicians had increased from 91.96分, 95.38%, and 91.62% in 2019 to 93.75分, 98.47%, and 93.68% in 2022, as well as the stopping rate of expert outpatient services had decreased from 5.26% to 1.86%. This practice of homogeneous management had achieved good results, so as to provide references for other hospitals to carry out homogeneous management of outpatient services in their campuses.

Objective:To investigate the clinical efficacy of robotic navigation and percutaneous internal fixation in the treatment of fresh undisplaced scaphoid lumbar fractures.Methods:From November 2019 to October 2020, 8 patients were treated at Department of Hand Surgery, Xuzhou Renci Hospital for fresh undisplaced scaphoid lumbar fractures. There were 7 males and one female with an average age of 27.5 years (from 18 to 42 years), and 5 left and 3 right cases. Navigation by a Tianji orthopedic robot was conducted to decide the positions for implantation of percutaneous Herbert screws to fixate the fractures. The bone healing was followed up by regular X-ray and CT examinations. The functional recovery was evaluated by Mayo wrist score, grip strength, pinch strength and wrist range of motion, and the wrist pain was evaluated by visual analogue scale (VAS).Results:All the 8 patients were followed up for a mean time of 12.8 months (from 6 to 19 months). All the wounds healed by the first intention without any inflammation or infection. CT examination at 3 months postoperation found that all the fracture ends got united. At the final follow-up, the average active motions of the injured wrist were: 67.9° in flexion, 64.1° in extension, 21.2° in radial deviation and 52.2° in unlar deviation, respectively. The average grip strength was recovered to 31.3 kg, reaching up to 85.2% (from 66.7% to 100.0%) of the contralateral wrist; the average pinch force was recovered to 19.5 kg, reaching up to 89.3% (from 77.8% to 100.0%) of the contralateral wrist. At the last follow-up, the Mayo wrist function scores averaged 97.5 (from 95 to 100) and all the 8 cases were excellent. The VAS pain score of the wrist averaged 0.88 (from 0 to 2).Conclusion:In the treatment of fresh undisplaced scaphoid lumbar fractures, navigation with a Tianji orthopedic robot can be used to visualize percutaneous minimally invasive screw fixation so that accurate positioning and precise screw placement are ensured, leading to rapid rehabilitation.

Objective:To evaluate the treatment of pseudoarticular scaphoid nonunion with bone graft and percutaneous fixation under wrist arthroscopy.Methods:Six patients with pseudoarticular scaphoid nonunion were treated with arthroscopic debridement, bong grafting and percutaneous fixation between October 2015 and October 2018 at Department of Hand Surgery, Xuzhou Renci Hospital. They were 5 men and one woman with 4 left and 2 right sides affected, aged from 28 to 51 years (mean, 39.5 years). The sclerotic bone was erased under wrist arthroscopy. Percutaneous fixation started after autoallergic cancellous bone chips were implanted and impacted through a sleeve inserted via the medial carpal approach. For the nonunion with a pseudarthrosis connecting the midcarpal and radiocarpal joints, we put an inflated Foley catheter through a 3/4 portal underneath the proximal edge of the pseudarthrosis to block the possible leakage of the small cancellous bone chips. The wrist functions were evaluated at the final follow-up using the modified Mayo elbow performance score (MEPS); the flexion-extension motion and ulnar-radial deviation of the wrist were recorded.Results:The operation time for the 6 patients ranged from 2 to 4 hours (average, 3.2 hours); their follow-up duration ranged from 6 to 15 months (average, 11.3 months). All the patients obtained bony union after 8 to 14 weeks (average, 12.1 weeks). The flexion-extension motion of their affected wrist ranged from 75° to 135° (average, 107.0°), accounting for 85% of that of the healthy side; the ulnar-radial deviation of their affected wrist ranged from 40° to 80° (average, 51.5°), accounting for 88% of that of the healthy side. MEPS at the final follow-up revealed 4 excellent, one good and one fair cases.Conclusion:Arthroscopic bone grafting and percutaneous fixation is a reliable and effective minimally invasive treatment for pseudarthrotic scaphoid nonunions.

Objective:To investigate the application and effect of frontal flap combined with tarsalconjunctiva flap in the repair of widely full-thickness defects of the lower eyelid.Methods:From January 2016 to March 2018, 9 patients with extensive full-thickness lower eyelid defect were admitted to the Plastic Surgery Department of Changhai Hospital Affiliated to the Naval Military Medical University. All the lengths of lower eyelid defects were greater than a half of the full length. Then we designed forehead flaps combined with tarsalconjunctival flaps to cover the wounds. The second stage operation was done after 4-6 weeks to cut the pedicle and dress the eyelid.Results:All the frontal flaps of 9 patients survived. One patient had lower eyelid retraction and the lid position returned to normal half a year later. One underwent thinning surgery because of lower eyelid flap hypertrophy and one were because of pedicle hypertrophy. The appearance and function of other patients were greatly improved after surgery, and they were satisfied with the operation effect. No repair operation was performed in the future.Conclusions:The frontal flap with good quality of blood supply has a high survival rate and can be used to repair the wide defect of the lower eyelid with tarsalconjunctival flaps.
