Objective:To observe the path and anatomic distribution of cutaneous branch of second dorsal metacarpal artery(SDMA) from the back of hand to the web of the fingers, and to explore the feasibility and clinical effect on the transfer of free flap of SDMA.Methods:Between June 2018 and September 2018, with perfusion of red latex, 22 hand specimens were dissected to explore the course, vessel calibre and distribution of cutaneous branches of SDMA, and to discover the existence of an innervation of cutaneous nerve in Department of Hand Surgery of Tangshan Second Hospital. Later on, from February 2019 to July 2020, 2 thumb pulp defects of 2 patients were reconstructed with the free flaps of SDMA. One defect was in the left thumb and the other in the right, both were male and compression injuries. Size of thumb pulp and a skin defect was at 3.5 cm×2.0 cm in 1 patient, and 2.0 cm×2.5 cm in the other. There was no neurovascular injury, but 1 patient had a distal phalangeal fracture and a nail bed laceration. The sizes of the flaps were 3.8 cm×2.3 cm and 2.8 cm×2.5 cm. Functional exercises started from 3 weeks after surgery. Patients attended postoperation follow up regularly by outpatient visit, telephone or internet interviews. Follow-up observations included the appearance, texture, sensory recovery of the flaps and thumb functions.Results:Multiple perforating branches (4-9 branches) were found from SDMA, which distributed in the distal 1/3 of SDMA in the anatomic study. It was found that the outer diameter of SDMA was 0.76 mm±0.25 mm at the intersection of extensor tendon of index finger and that of the digital web artery was 0.71 mm±0.12 mm. The length of digital web artery was 11.00 mm±1.27 mm. The 2 surgically transferred flaps were all survived. One patient showed the function of thumb in excellent with two-point discrimination (TPD) at 7.0 mm, at 18 months of follow-up. The other patient showed good thumb movement, soft and elastic skin of the flap and with a 7.5 mm in TPD, at 15 months of follow-up. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the results of the 2 flaps were all excellent.Conclusion:The flap of SDMA has a constant cutaneous nerve and a long vascular pedicle with an ideal vessel size. It is suitable for free transfer and can be used to reconstruct soft tissue defects of thumb.

Objective:To explore the effects of 3 osteotomy methods on the bone healing in Ilizarov tibial bone transport.Methods:The data of 93 patients were retrospectively reviewed who had been treated by Ilizarov single-segment tibial bone transport at Department of Hand Surgery, The Second Hospital of Tangshan from December 2003 to April 2019. Minimally invasive osteotomy was performed in 16 patients [group A: 16 males with an age of (37.1±8.3) years; 5 cases of type Ⅱ and 11 ones of type Ⅲ by Gustilo classification], subperiosteal saw osteotomy in 57 patients [group B: 47 males and 10 females with an age of (39.1±11.8) years; 17 cases of type Ⅱ and 40 ones of type Ⅲ by Gustilo classification] and extraperiosteal wire saw osteotomy in 20 patients [group C: 19 males and one female with an age of (37.7±11.2) years; 18 cases of type Ⅱ and 2 cases of type Ⅲ by Gustilo classification]. The 3 groups were compared in terms of the bone healing index and the Association for the Study and Application of the Method of Ilizarov (ASAMI) functional scores.Results:The 3 groups were comparable because there was no significant difference in the preoperative general data between them ( P>0.05). All the patients were followed up for 19 to 50 months (average, 27.4 months). All patients achieved bony healing, and their associated complications were cured after corresponding treatments. There were no significant differences in the bone healing index between the 3 groups [(53.09±21.88) d/cm for group A, (59.97±33.29) d/cm for group B and (46.20±14.11) d/cm for group C] ( P>0.05). There were no significant differences either in the good to excellent rate by the ASAMI functional scores between the 3 groups (87.5% for group A, 89.5% for group B and 90.0% for group C) ( P> 0.05). Conclusion:All the 3 osteotomy methods may achieve good bony union, leading to similar bone healing indexes and postoperative functional scores.

Objective:To explore clinical results in reconstruction of finger C-shape soft tissue defect with the wrist crease free flap carrying cutaneous nerve.Methods:From June, 2017 to April, 2019, 7 fingers(7 patients) with C-shape defect were treated with the wrist crease free flap carrying cutaneous nerve. The size of defect ranged from 1.0 cm × 2.5 cm-2.2 cm × 4.0 cm; the flap sizes were 1.3 cm × 2.7 cm-2.5 cm × 4.5 cm. Five fingers had unilateral defect of proper palmar digital artery. Two fingers that had bilateral defect of proper palmar digital artery with poor blood circulation were re-established with blood supply by Flow-through flaps. Four fingers had unilateral defect of proper palmar digital nerves, and 3 had bilateral defect of proper palmar digital artery. Five of the fingers were repaired by the superficial branch of the radial nerve and 2 repaired by palmar cutaneous branch of median nerve. Regular outpatient follow-up was conducted after surgery for 8 to 15 (mean 11) months.Results:All the fingers and flaps survived with primary healing. Numbness existed in the areas of functional dominance of the cutaneous nerve. At the end of follow-up, the flaps showed good texture without significant bloated appearance with the recovery of protective sensation. The sensation of fingertip recovered to S 4 in 5 fingers and S 3+ in 2 fingers. Finger pulps were plump. All of the fingers moved freely. Linear scars were observed at donor sites and the wrists moved freely. Numbness feeling in the areas of cutaneous nerve disappeared at 6 to 8 weeks after surgery. According to the Functional Evaluation Criteria of the Finger Replantation published by the Hand Surgery Society of the Chinese Medical Association, the results were excellent in 6 fingers and good in 1 finger. Conclusion:The wrist crease free flap carrying cutaneous nerve is constant and can be dissected transversely to reconstruct and fit the C-shape defect of finger. It can re-establish the blood supply as well as to repair the proper palmar digital nerve defect at the same time.

Epimedii Folium has a long history in China as a common traditional Chinese medicine. Key factors of Epimedii Folium quality were summarized based on ancient literatures, Chinese Pharmacopoeias and modern research in different period of history. The main reason for unqualified Epimedii Folium is unstable icariin. Therefore, it's suggested that: the precondition of the quality control of epimedium is to find the proper quality marker. It's suggested that the medicinal parts should be reverted to "dry whole plant overground" to solve Epimedium resource shortage problem. In addition, it is necessary to strengthen the standardized cultivation, so as to ensure germplasm, production area, and producing method to guarantee the quality of Epimedium Folium. In the drying method, it is recommended to change "dry in the sun or shade" to "dry", namely dry in the sun, shade or drier, in order to provide a new method to improve the quality control and quality standard of Epimedii Folium.

Objective To evaluate the outcomes of distal leg and foot-ankle reconstruction with rotated single pedicel reverse sural neurocutaneous island flaps. Methods From June 2011 to January 2016, seventeen distal leg and foot-ankle defects cases repaired with rotated single pedicel reverse sural neurocutaneous island flap were analyzed retrospectively. In this study, 13 cases were male, and 4 cases were female. Age ranged from 25 to 65 years old, with an average age of 42.0 ± 8.3 years. Seven cases were distal leg defects, 3 cases were ankle defects, 3 cases were heel defects, and 4 cases were acrotarsium defects; all cases had bone and tendon exposure. The defects ranged from 5.0 cm × 7.0 cm-6.0 cm × 12.0 cm. The flap size ranged from 5.0 cm × 7.0 cm-8.0 cm × 15.0 cm. Results All 17 cases survived completely, without thanatosis, blisters and vascular crisis. The follow-up period was 12-48 months, and the mean was (20.0 ± 11.1) months. The color and elasticity of the flaps was excellent, with satisfactory appearances. Function and appearance of donor sites was not affected. Conclusions The rotated single pedicel reverse sural neurocutaneous island flaps have no injury on main nerves and arteries. The flaps have wide rotation angle and less invalid fold in the pedicel. The simple operation has satisfactory effects and high survival rate. It is a relatively easy procedure that can be applied toward repairing of distal leg and foot-ankle soft tissue defect.

Objective To recognize the relationship between high cutantous artery branches and descending branch of lateral femoral circumflex artery artery,and to investigate the blood supply of anterolateral thigh flap in clinical.Methods Retrospective analysis 152 cases of anterolateral thigh flap from November,2003 to December,2016.It contains cutting with descending branchs in 99 cases,cutting with lateral branchs in 43 cases,the union of them in 8 cases and high cutantous artery branches in 2 cases.Results The flaps survival in 147 cases,cutting necrosis in 3 cases and partly necrosis in 2 cases.Descending and lateral branchs were both dominance neurovascular bundle of vastus lateralis muscle,independently or commonly dominate the skin of anterolateral thigh,occurrence rate was 33.5％.Conclusion The descending branch of lateral femoral circumflex artery include lateral branch,all of which are the neurovascular bundles,supply the anterolateral thigh muscle,and divid into some perforator branches crossing the musle to the anterolateral thigh skin subsequently,which constitute "the anatomical functional unit".High cutantous artery branche is the one of all of the branches,its origin lies hight and arise from lateral branch.

BACKGROUND: There are various kinds of design methods about preoperative osteotomy of ankylosing spondylitis with kyphosis, but each has their own errors and limitations. A convenient, precise and available method needs to bedeveloped.OBJECTIVE: To compare the clinical efficacy of two different preoperative osteotomy designs using paper-cut andphotoshop software for ankylosing spondylitis with kyphosis.METHODS: Thirty-nine patients suffering ankylosing spondylitis with kyphosis undergoing osteotomy in the Departmentof Spinal Surgery, Affiliated Hospital of Yan'an University between June 2009 and January 2015 were enrolled, andrandomly allotted to paper-cut (n=19) and photoshop (n=20) groups, followed by the preoperative osteotomy design,respectively. All patients were followed for 12-40 months to compare the postoperative osteotomy angle error andcorrection efficacy at the last follow-up between groups.RESULTS AND CONCLUSION: (1) The postoperative osteotomy angle error in the photoshop group was significantly smaller than that in the paper-cut group (P < 0.05). (2) At the last follow-up, the key parameters of sagittal spine and pelvis (sagittal vertical axis, Cobb angle and pelvic tilt) showed significant differences between groups (P < 0.05). (3) The Oswestry disability index and Scoliosis Research Society-22 questionnaire scores in the photoshop group weresignificantly superior to those in the paper-cut group at the last follow-up (P < 0.05), while the visual analog scale scoresdid not differ significantly between groups (P > 0.05). (4) To conclude, compared with the osteotomy design usingtraditional paper-cut splice, the photoshop software can achieve a smaller osteotomy angle error and better postoperative balance of spinal sagittal plane, thus providing precise osteotomy for surgeons to obtain proper correction.

Objective To evaluate the outcomes of thumb reconstruction with dorsal thumb rotated single pedicel reverse island flap.Methods 49 thumb-tip defects cases with dorsal thumb rotated single pedicel reverse island flap were analyzed retrospectively.37 dorsal thumb reverse island flap were performed,and 12 ulnar-dorsal reverse island flaps were performed.Results The operation time was 40-60 minutes.The mean time was 45 minutes.All 49 cases survived completely.The color of the flaps was purple,and blisters in the surface of the flaps after 1-2 days in 2 cases.After took out stitches partly,the blisters were dried and crusted,the color of the flaps with better blood circulation was normal.The follow-up period was 3-24 months,all thumbs had satisfactory appearances and functions.The two-point discrimination was 6-9mm in flaps inosculated with nerve,that was 8-10 mm in flaps inosculated without nerve.The color,texture and elasticity of flaps were excellent,and the donor sites had not been defected.Conclusion Dorsal thumb rotated single pedicel reverse island flap is a reliable option to restore function as well as appearance,long vascular pedicle with skin strap,wide rotation angle,high rate of survival.It avoided damages to the well-known arteries and nerves.It is a relatively facile procedure that can be applied toward resurfacing thumb tip defects.
