穿支皮瓣是在传统轴型皮瓣基础上发展而来,以穿支血管供血,仅包括皮肤与浅筋膜组织的一种新型皮瓣,由于改变了深筋膜血管网是皮瓣赖以生存的传统观点,使皮瓣设计和形成更具灵活性和多样性 [ 1, 2, 3] 。2012年唐举玉 [ 4] 在国际上首次提出的特殊形式穿支皮瓣是应用传统穿支皮瓣的"微创与美学"理念、根据受区修复要求对皮瓣供区的一级源血管及其分支和相应供养的组织（皮肤、筋膜、肌肉、骨组织）进行优化设计、无创解剖、分割和重组,根据受区创面重建需要切取不同组织块（嵌合）或相同组织块（分叶）,然后再削薄、组装、拼接成与受区创面内容、形状及血液循环重建要求相匹配的新型皮瓣。特殊形式穿支皮瓣是传统穿支皮瓣的衍生和发展,是穿支皮瓣的更高形式,丰富了穿支皮瓣的内涵,扩大了穿支皮瓣的适应证 [ 5, 6, 7, 8, 9, 10, 11, 12, 13] 。

Purpose The aim of the study was to provide an applied and digital anatomical basis of acquiring extended deep inferior epigastric perforator (DIEP) flaps for clinical use. Methods Five formalin-soaked specimens were received red latex injection and dissected by layers. The arteriography using the modified mixture of lead oxide-gelatin was performed on 10 adult cadavers that were serially scanned by a spiral computed tomography. The DIEPs were 3 dimensionally reconstructed by Mimics. Results The medial row perforators of DIEP arteries are located in the medial 1/third of rectus abdominis muscle, and lateral row perforators in the lateral 1/third of the muscle. The perforators distribute mainly from the upper tendinous intersection of umbilicus to below umbilicus within 8.0 cm, especially 4.0 cm. There are constant diameter 0.8-mm perforators or greater accompanied with nerveswithin this region. The main perforators are shown by fast direct volume rendering (VR) reconstruction method, and 3-dimensional images of DIEPs are acquired by dynamic reconstruction (DR) method. Consecutively, the adjacent perforators can be combined freely and the position and anastomosis of extended branches can be easily observed. The extended DIEP flaps were designed by VR and DR methods. Conclusions The DIEPs can obtain large extended perforator flaps accompanied with nerves. The perforator close to the umbilicus should be selected while designing the DIEP flap. The 3-dimensional model of extended DIEP flaps can be established conveniently and intuitively by VR and DR methods of Mimics.

腹壁下动脉穿支皮瓣（DIEP）具有血管恒定、管径粗、可切取的组织量大、供区隐蔽、损伤小和可直接闭合等优点，已成为乳房重建或整形的首选皮瓣，广泛应用于乳房再造。经改良与发展，也较多应用于头颈部、躯干和四肢等部位创面的修复和器官再造，是几个最常用的穿支皮瓣之一。然而，有关DIEP的应用方面有些观点不一，亟待一份专家指导意见。中华医学会显微外科学分会和《中华显微外科杂志》编辑部组织专家讨论DIEP的应用解剖、适应证、应用设计类型、手术方法、优点和缺点、术后主要并发症、预防措施,以及术后护理与康复，形成DIEP专家共识。

穿支螺旋桨皮瓣(perforator pedicled propeller flap, PPPF)作为穿支皮瓣的一种特殊形式,近年来因其供区损伤更小、组织浪费更少和修复效果更佳等优点,已在临床上日渐普及.其修复范围已涉及面部、躯干、会阴部及四肢等,逐渐成为创面修复的一种重要方法[1-9].然而,在应用过程中,有关PPPF 的概念、命名、手术方法、围手术期处理及并发症等方面仍存在争议.为此,在徐永清教授倡导下,在2018年昆明召开的第12届中华医学会显微外科学术会议上,《中华显微外科杂志》编辑部组织相关专家拟定《穿支螺旋桨皮瓣专家共识》,几经讨论,以期方便学术交流与争鸣,促进PPPF的临床应用和进一步发展.

Category: Hindfoot Introduction/Purpose: The aim of this study was to evaluate the occurrence of anatomical variations of the musculotendinous junction of the flexor hallucis longus (FHL) muscle, the relationship between FHL tendon or muscle and the tibial neurovascular bundle at the level of the posterior ankle joint in human cadavers. Methods: Seventy embalmed feet from 20 male and 15female cadavers, the cadavers’ mean age was 65.4 (range from 14 to 82) years, were dissected and anatomically classified to observe FHL muscle morphology define the relationship between FHL tendon or muscle and the tibial neurovascular bundle . The distance between the musculotendinous junction and thehe relationship between FHL tendon or muscle and the tibial neurovascular bundle was determined. Results: The three morphology types of FHL muscle were identified: a long lateral and shorter medial muscle belly, which was observed in 63 specimens (90%).; equal length medial and lateral muscle bellies, this variant was only observed in 5 specimens (7.1%); a lateral and no medial muscle belly, which was observed in 2 specimens (2.9%). No statistically significant difference was observed according to gender or side (p > 0.05). Two patterns were identified and described between FHL tendon or muscle and the tibial neurovascular bundle. Pattern 1, the distance between the neurovascular bundle and FHL tendon was 3.46 mm (range, 2.34 to 8.84, SD = 2.12) which was observed in 66 specimens (94.3%); Pattern 2, there was no distance which was observed in 4 specimens (5.7%). Conclusion: Knowing FHL muscle morphology variations provide new important insights into secure planning and execution of a FHL transfer for Achilles tendon defect as well as for the interpretation of ultrasound and magnetic resonance images. During posterior arthroscopic, posteriormedial portal may be introduced into the posterior aspect of the ankle without gross injury to the tibial neurovascular structures.

传统皮瓣移植的治疗目标主要是追求皮瓣成活和创面愈合,对皮瓣受区的外形与功能恢复、特别是对皮瓣供区损害问题未引起足够重视.临床随访发现部分患者皮瓣移植术后供区存在难看的瘢痕、甚至严重的功能障碍,对患者身心造成严重影响[1-2].随着人们生活水平的提高,一方面对创面重建的要求越来越高,要求受区创面修复后能够获得最好的外形和功能;另一方面期望皮瓣供区的外观和功能损害尽可能最小化.随着皮瓣外科技术和相关技术的发展,特别是穿支皮瓣技术的诞生[3-5],为人们美好期望的实现奠定了基础.穿支皮瓣技术的精髓是"微创与美学",其临床应用遵循"最大得失比"原则,即以最小的供区损害获得最佳的受区外形和功能,在重视皮瓣受区外形和功能重建的同时尽可能减少皮瓣供区外观和功能的损害[5-8].

A better understanding of the blood supply of the femoral head is essential to guide therapeutic strategies for patients with femoral neck fractures. However, because of the limitations of conventional techniques, the precise distribution and characteristics of intraosseous arteries of the femoral head are not well displayed.

The transfer of the flexor hallucis longus tendon or flexor digitorum longus tendon is frequently used for the treatment of posterior tibial tendon insufficiency or chronic Achilles tendinopathy. According to several anatomical studies, harvesting the flexor hallucis longus (FHL) tendon may cause nerve injury. Sixty-eight embalmed feet were dissected and anatomically classified to define the relationship between Henry's knot and the plantar nerves. Two different configurations were identified. In Pattern 1, which was observed in 64 specimens (94.1%), the distance between the medial plantar nerve and Henry's knot was 5.96 mm (range, 3.34 to 7.84, SD = 1.12). In Pattern 2, which was observed in 4 specimens (5.9%), there was no distance between the medial plantar nerve (MPN) and Henry's knot. No statistically significant difference was observed according to gender or side (p > 0.05). A retraction was performed to harvest the FHL through the posteromedial hindfoot incision using a single minimally invasive technique, and the medial and lateral plantar nerve lesions were scrupulously assessed. In conclusion, medial and lateral plantar nerve injuries did not occur more frequently, even after performing a single minimally invasive incision to harvest the FHL tendon, due to the large distance between the FHL tendon and the medial and lateral plantar nerves.

Objective To prospectively summary the piercing-out position,direction,length and piercing-in position of perforator,and investigate the feasibility of preoperative design and optimization of the anterolateral thigh flap and its clinical application.Methods All 58 cases of anterolateral thigh flaps were designed and taken from the lateral thigh area from January,2014 to January,2016.Portable Doppler ultrasound was used before an operation to detect the piercing-out position (point P) of perforators.The direction and length (lower subcutaneous segment of perforators) of perforators after leaving piercing-out position were observed during the operation.And the piercing-in positions (point P') on superficial fascia and the dermis were observed.Based on this,we added line B (anterior superior spine-lateral femoral epicondyle) and line C (anterior superior spine-the middle point of superior border of patella) in the lateral and anterior side of original ilium-patella line in the thigh (line A),respectively.Results All perforators found in 58 cases before and during the operations were located on line A or between line A and line B.No perforators were found between line A and line C.Perforators walked toward the anterior medial side after leaving the muscle membrane.The perforator vascular subcutaneous segment (distance between point P and point P') was (2.02±0.23) cm.There was rectus muscle branch in the descending branch of lateral femoral circumflex artery,while no rectus muscle cutaneous branch was seen.20 cases were designed by one-line method,12 cases were designed by two-line method,while 26 cases were designed by three-line method.Conclusion Advanced three-line method is beneficial to detect of the perforators on the anterior thigh lateral region and to reduce the intraoperative injury perforator vessels at the puncture point.Clinical application of the anterior lateral thigh flap is simple and reliable.

Objective To evaluate the effectiveness of flexor hallucis longus tendon transfer in treatment of chronic Achilles tendinopathy using different technique.Methods Sixty-four embalmed feet of 32 cadavers were analyzed and classified anatomically with respect to the individual cross links in the Henry's knot.These three techniques were then combined to determine the total potential tendon graft length obtainable using single incision,double incision and minimally invasive incision.From January,2012 to June,2015,10 patients (10 feet) with chronic Achilles tendinopathy were treated with double incision technique.The score was 63.04 ±7.75 according to American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system.Results Only two different configurations were found.Type 1,a tendinous slip branched from the FHLT to the FDLT was 96.9％(62 of 64 feet).Type 2,a slip branched from the FHLT to the FDLT and another slip from the FDLT to FHLT was 3.1％(2 of 64).The average length of the FHLT graft available from a single incision measured (5.08±1.09)cm,double incision technique measured (6.72 ± 1.02) cm,and minimally invasive incision measured (17.49 ± 1.80)cm.The difference between the lengths obtained from these three techniques was statistically significant.Ten patients were followed-up 12-36 months (mean,13.7 months).At 12 months after operation,the AOFAS ankle and hindfoot score was 93.28 ± 3.72,showing significant difference when compared with that before operation.The results were excellent in 6 cases,good in 3 cases,and fair in 1 case with an excellent and good rate of 90％.No sural nerve injury,posterior tibial nerve injury,medial plantar nerve injury,and lateral plantar nerve injury occurred.Conclusion In over 96 ％ of the feet,a proximal to distal connection from the FHLT to the FDLT was found,which might contribute to the residual function of the lesser toes after FDLT transfer.The distal stump of the FHLT tendon should be sutured onto the FDLT tendon under tension to en able a co-activation of the great toe,preserved hallux plantar flexion.Chronic Achilles tendinopathy reconstruction with flexor hallucis longus tendon harvested using double incision technique offers a desirable outcome in operative recovery,tendon fixation,preserved hallux plantar flexion and less complications.

桡骨远端骨折是上肢最常见的骨折，其骨折类型、生物力学和有关治疗策略一直备受争议。研究显示，临床上许多长期应用的治疗原则和方案需要进一步与循证医学的研究证据相结合。本文拟对桡骨远端骨折在治疗上存在的焦点问题进行综述，以拓展我们的思维并接受一些启发式的方式方法。

We describe a technique for perfusing a barium sulphate suspension into the intraosseous artery. Following the perfusion of abarium sulphate suspension into 14 fresh lower limbs of Chinese cadavers, micro‐CT scanning was applied to digitize, quantify and visualize the intraosseous arteries in the human femoral heads. Then, the femoral heads were removed and subjected to micro‐CT scanning. The data were imported into the amira and mimics programs to reconstruct and quantify the intraosseous arteries. The femoral head intraosseous artery lengths, areas, volumes, and femoral head bone volumes were quantified. The artery densities and artery ratios were calculated and analysed with independent‐samples t‐tests. The intraosseous vasculature volume renderings were displayed as screenshots and videos made with amira. Many intraosseous artery study technologies were compared. The barium sulphate suspension was milky white in colour. The perfusion of the barium sulphate suspension followed by micro‐CT scanning provided a good representation of the intraosseous artery. The femoral head intraosseous artery lengths, areas and volumes, and the femoral head bone volumes were displayed as the X¯±S . No differences were observed between the left and right femoral head intraosseous arteries in terms of the artery densities or artery ratios. The volume renderings and 3‐D orthogonal projections displayed the overall distributions of the intraosseous arteries. The videos clearly demonstrated the entry sites of the nutrition‐carrying arteries, their courses and branches, and the intraosseous arterial anastomoses. Our technique is the simplest and least time‐consuming method of producing accurate vascular three‐dimensional reconstructions. The perfusion of a barium sulphate suspension into intraosseous arteries combined with micro‐CT scanning can deliver high‐resolution 3‐D digitized data and images of intraosseous arteries. This technique does not require bone decalcification or bone dissection and thus significantly shortens the time required to quantify and display intraosseous arteries. This method provides a simple and rapid technique for quantifying and visualizing human intraosseous arteries.

随着新技术的飞速发展，不同学科、不同领域之间的融合不断加深。新时期的皮瓣研究者眼界得到前所未有的开阔，为顺应时代的发展，也必须站得更高，看得更远。无论是已经存在的临床问题，还是潜在的临床问题都要求我们勇于探索，善于利用新知识、新方法。本文将对近年来与穿支皮瓣领域发展密切相关的新概念、新技术和新方法做一述评。

皮瓣手术的应用在人类史上已有两千多年，其发展主要经历了最初的局部旋转皮瓣和后来的远位带蒂皮瓣、游离皮瓣、带血管蒂皮瓣、穿支皮瓣等阶段。近40余年来由于显微外科技术的诞生解决了小血管吻合难题和显微解剖研究深入认识了皮瓣的血供规律，先后诞生了游离皮瓣和穿支皮瓣。游离皮瓣解决了过去处理极为棘手、治疗效果不佳甚至无法修复的创面难题，是皮瓣外科发展史上重要的里程碑；穿支皮瓣突破了深筋膜血管网是皮瓣赖以生存必备条件的传统观念，使皮瓣移植迈向了“自由王国”，实现了以最小的供区损害获得最佳的受区外形和功能，代表目前皮瓣外科的最新进展，是皮瓣外科发展史上又一次飞跃。

OBJECTIVE:To investigate the effect of reverse saphenous nerve neurocutaneous flaps for skin defects of forefoot.METHODS:In the anatomic study, 50 cadaveric feet were injected with red latex and the anastomosis, distribution and external diameters of medialtarsal artery, medial anterior malleolus artery, medial plantar artery, the superficial branch of the medial basal hallucal artery and saphenousnerve nutritional vessels were observed. Based on anatomic research results, we designed the reverse saphenous nerve neurocutaneous flaps for repairing skin defects of forefoot.RESULTS:The blood supply of reverse saphenous nerve neurocutaneous flaps were based on the vasoganglion, which consist of arterial arch at the superior border of abductor hallucis and arterial network on the surface of abductor hallucis around the saphenous nerve and medial pedis flap. From Oct. 2006 to Oct. 2011, the reverse saphenous nerve neurocutaneous flaps were used to repair skin defects of forefoot in 11 cases. The flap size ranged from 2.5 cm x 3.5 cm to 7.5 cm x 8.5 cm. The wounds at donor site were covered with full-thickness skin graft. All flaps survived completely with no ulcer at the donor site. 11 cases were followed up for 6 to 18 months( mean, 10 months). The skin color and texture were satisfactory. The patients could walk very well.CONCLUSIONS:It is reliable to repair the skin defects of forefoot with reverse saphenous nerve neurocutaneous flaps. It is easily performed with less morbidity. This flap should be considered as a preferential way to reconstruct skin defects of forefoot.

OBJECTIVETo explore the method of the treatment for hallux valgus with the proximal crescentic osteotomy of the first metatarsal bone, combining with distal lateral soft tissue release.METHODSFrom January 2008 to December 2012, 21 cases 21 hallux valgus feet were treated by operative procedure, included 1 male (1 foot) and 20 females (20 feet), with the mean age of 52 years (range, 36-68 years). Among all patients were followed up for 12 to 26 months, with the mean 16 months. The preoperative, post-operative and final follow-up X-ray films of all patients were collected. The hallux valgus angle, intermetatarsal angle and distal metatarsal articular angle were measured and analyzed. The surgical outcome was evaluated combined with the AOFAS score.RESULTSThe average hallux valgus angle decreased from 42.3° ± 1.8° preoperatively to 14.5° ± 1.8 postoperatively, the average intermetatarsal angle did from 21.9° ± 1.7 to 9.1° ± 1.8°, and the average distal metatarsal articular angle did from 14.9° ± 1.8 to 7.2° ± 1.5, respectively. There were significant differences between the preoperative and postoperative roentgenographic index. AOFAS score was improved from 44.0 ± 1.8 preoperatively to 83.9 ± 2.2 at the final follow-up.CONCLUSIONSThe proximal crescentic osteotomy of the first metatarsal bone combined distal soft tissue reconstruction obtained satisfactory results in severe hallux valgus patients with big intermetatarsal angle.

Neglected Achilles Tendon Ruptures are commonly seen by orthopaedic surgeons. In cases resistant to conservative treatment, a variety of surgical procedures have been utilized in the past. The senior -surgeon at our institution has utilized a technique -employing two turndown fascia flaps fashioned from the proximal Achilles tendon augmented by a tenomyodesis of the flexor hallucis longus and plantaris tendon. The purpose of this study was to assess the clinical outcome of all patients who underwent this procedure. The medical records of 10 cases that underwent this procedure were retrospectively reviewed. We completed data collection sets using the American Orthopaedic Foot and Ankle Society ankle-hind foot scores, isokinetic evaluation, and postoperative magnetic resonance imaging (MRI) at 1 year of follow-up. The mean American Orthopaedic Foot and Ankle Society ankle-hind foot scores improved from 64.4±3.54. Isokinetic testing at 30º/sec and 120º/sec revealed an mean deficits of 24.5%, respectively, in the plantar flexion peak torque of the involved ankle than non-involved ankle. The flexor hallucis longus tendon, gastrocnemius fascia flap and plantaris were well -integrated into the Achilles tendon forming a homogenous tendon, which was confirmed in MRI. Our subjective and objective data indicate that the reconstructive technique using flexor hallucis longus transfer with two turndown gastrocnemius fascia flaps and plantaris tendon is a good option for repairing large gap defect of Achilles tendon.

The fracture of the distal ulna and radius is a kind of fracture that results in high morbidity and occurrence rate and contributes to about one-sixth of the entire body’s fracture. In this study, we implemented the improved palmar wrist surgery by a volar wrist dual channel approach. Between 2011 and 2014, we have treated 67 distal radius fracture patients. We divided them into two parts randomly, and treat them by the Carpometacarpal direct approach solution and dual wrist palmar surgical approach solution respectively. After the surgery, the differences in the incidence of median nerve irritation are significant (P < 0.01). With reference to the exposure time of fracture, the operation time and the pronator quadratus muscle repair rate, we find that the exposure time of fracture and the operation time in the dual wrist palmar surgical approach solution are much less than that as compared to the Carpometacarpal direct approach solution (P < 0.01). The improved dual wrist palmar surgical approach can lead to a successful treatment of the distal radius fractures volar distal radial ulnar by reducing the blind exposure problem. As such, the surgeon can complete treatment of fractures of the region under direct vision during operation. Furthermore, reducing the median nerve in the carpal tunnel and the structure of the stretch can decrease the incidence of postoperative complications. Postoperative X-ray diagnosis is then performed to examine the patients’ recovery and assist in clinical follow-up. Our study proves that the volar wrist dual channel approach can be successfully achieved by a surface incision surgical implementation of the dual channel, and gives rise to a minimally invasive operation.

The purpose of the study was to describe the anatomical variations of the connection between the flexor hallucis longus (FHL) and flexor digitorum longus (FDL) tendons in the knot of Henry in Asians, and quantify the length of FHL tendon graft with different incisions.
