Objective: To explore the clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux. Methods: A retrospective observational study was conducted. From January 2020 to January 2021, 13 patients with skin and soft tissue defects of the hallux who met the inclusion criteria were admitted to Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 12 males and 1 female, aged 26 to 53 years. Before operation, the perforating point of the superficial peroneal artery perforator was located by color Doppler ultrasound on the calf on the same side of the affected hallux and marked on the body surface. The operation was performed under spinal anesthesia combined with continuous epidural anesthesia. The area of skin and soft tissue defect after debridement was 4.5 cm×2.5 cm to 12.0 cm×3.0 cm. According to the size and shape of the wound, the superficial peroneal artery perforator flap was designed with the line between the fibular head and the lateral malleolus tip parallel shifting 2 cm to the tibial side as the flap axis line, and the perforating point of the perforator near the midpoint of the axis line as the center. The cut area of the flap was 5.0 cm×3.0 cm to 13.0 cm×4.0 cm, and part of the deep fascia was cut when the pedicle was freed. The donor site wound was sutured directly. During the operation, the number and type of the perforator and the cutting time of the flap were recorded, and the length of the perforator pedicle and diameter of the perforator were measured. The survival of the flap, the healing time and the healing condition of the donor and recipient areas were recorded after operation. The color, texture, elasticity of the flap, standing and walking functions of patients, the recovery of the donor area, and the patients' satisfaction with the recovery of the donor and recipient areas were recorded during the follow-up. At the last follow-up, the sensation of the flap was evaluated by the British Medical Association sensory function evaluation standard, the function of the affected limb was evaluated by the American Society of Foot and Ankle Surgery scoring system, and the excellent and good rate of the function of the affected limb was calculated. Results: A total of 13 perforators of the superficial peroneal artery were detected during the operation, all of which were septocutaneous perforators, and the perforator diameter was 0.3 to 0.5 mm. The vascular pedicle length was 2 to 5 cm. Flap cutting time was 11 to 26 minutes. The flaps of 13 patients all survived completely. The wounds at the donor and recipient sites healed well 9 to 18 days after operation. During follow-up of 6 to 14 months, the flaps had good color, texture, and elasticity; 11 patients had no obvious bloated appearance, and the other 2 patients underwent flap thinning and plastic surgery in the second stage because of their bloated appearance; all the patients returned to normal walking and standing functions. There was only one linear scar left in the donor site, with no obvious scar hyperplasia or hyperpigmentation. All the patients were satisfied with the recovery of the donor and recipient areas. At the last follow-up, the sensation of the flap was evaluated as grade S₃ in 2 cases, grade S₂ in 9 cases, and grade S₁ in 2 cases; the function of the affected limb was evaluated as excellent in 7 cases and good in 6 cases, with an excellent and good rate of 100%. Conclusions: The free superficial peroneal artery perforator flap has relatively constant vascular anatomy, which is thin and wear-resistant, with less damage to the donor site after flap excision, and can preserve the shape and function of the hallux to the greatest extent. It is an effective method for repairing skin and soft tissue defect of the hallux.

OBJECTIVE: To retrospectively evaluate the impact of pedal arch quality on tissue loss and time to healing in diabetic patients with foot wounds undergoing infrainguinal endovascular revascularization. MATERIALS AND METHODS: Between January 2014 and June 2015, 137 consecutive diabetic patients with foot wounds underwent infrainguinal endovascular revascularization (femoro-popliteal or below-the-knee, arteries). Postprocedural angiography of the foot was used to divide the patients into the following three groups according to the pedal arch status: complete pedal arch (CPA), incomplete pedal arch (IPA), and absent pedal arch (APA). Time to healing and estimated 1-year outcomes in terms of freedom from minor amputation, limb salvage, and survival were evaluated and compared among the three groups. RESULTS: Postprocedural angiography showed the presence of a CPA in 42 patients (30.7%), IPA in 60 patients (43.8%), and APA in 35 patients (25.5%). Healing within 3 months from the procedure was achieved in 21 patients with CPA (50%), 17 patients with IPA (28.3%), and in 7 patients with APA (20%) (p = 0.01). There was a significant difference in terms of 1-year freedom from minor amputation among the three groups (CPA 84.1% vs. IPA 82.4% vs. APA 48.9%, p = 0.001). Estimated 1-year limb salvage was significantly better in patients with CPA (CPA 100% vs. IPA 93.8% vs. APA 70.1%, p < 0.001). Estimated 1-year survival was significantly better in patients with CPA (CPA 90% vs. IPA 80.8% vs. APA 62.7%, p = 0.004). CONCLUSION: Pedal arch status has a positive impact on time to healing, limb salvage, and survival in diabetic patients with foot wounds undergoing infrainguinal endovascular revascularization.

Reconstruction of the lower extremities is difficult due to a lack of skin laxity and muscular tissues. Here, we present a case of lower extremity reconstruction via the anterior tibial artery perforator based segmental muscle island flap. Our patient was a 75-year-old male with a chronic ulcerative wound on the right lower leg from an old car accident. A 5.0×0.5 cm size ulcerative wound with tibial bone exposure was noted. We planned to reconstruct the lower extremity defect with a free flap, but the vessel status was severely compromised intraoperatively. Thus, we found the anterior tibial artery perforator using Doppler ultrasound, elevated the tibialis anterior muscle segment flap, and transposed it to cover the defect successfully. The flap presented with a nice contour and the skin graft covering the flap survived completely. There were no complications of the surgical site at three months follow-up and no gait morbidity. This is a meaningful case applying the concept of segmental muscle flap based on a perforator that had advantages including proper bulkiness, vascularization, and preservation of function, which were well applied, leading to great success.

Many complications have been reported during or after anterior cruciate ligament (ACL) reconstruction, including infection, bleeding, tibial tunnel widening, arthrofibrosis, and graft failure. However, arterial injury has been rarely reported. This paper reports a case of an anterior tibial arterial injury during bicortical tibial drilling in arthroscopic ACL reconstruction, associated with an asymptomatic occlusion of the popliteal artery. The patient had a vague pain which led to delayed diagnosis of compartment syndrome and delayed treatment with fasciotomy. All surgeons should be aware of these rare but critical complications because the results may be disastrous like muscle necrosis as in this case.

OBJECTIVETo investigate the therapeutic effect of V-Y advanced flap pedicled with perforator of peroneal artery at posterior lateral malleolus for small skin defect on children heel.

METHODSFrom Mar. 2012 to Jan. 2014, 9 children with small skin defects on heel were treated with adjacent V-Y advanced flap pedicled with perforator of peroneal artery at posterior lateral malleolus. The flaps were 8.0 cm x 4.0 cm to 9.0 cm x 4.5 cm in size and the wounds at donor sits were directly closed.

RESULTSAll flaps survived completely with primary healing. 9 cases were followed up for 6-12 months( average, 9 months). The flaps had good match with surrounding tissue in texture and color. The function of ankle was normal. All the parents were satisfied with functional and cosmetic results.

CONCLUSIONSIt is a safe and practical method for treatment of small skin defect on children heel with adjacent V-Y advanced flap pedicled with perforator of peroneal artery at posterior lateral malleolus.

Two aged patients who had open tibial fractures with arterial injury caused by high energy accidents underwent emergency arterial reconstruction using a greater saphenous vein and soft tissue repair using free flaps. In the patients, soft tissue necrosis developed and tibias were exposed at postoperative third week. Follow-up angiography through the superficial femoral artery showed occlusion of the anterior tibial artery. The anterior tibial artery was reconstructed using the contralateral greater saphenous vein graft and the latissimus dorsi myocutaneous and rectus abdominis muscle free flaps were transplanted for repair of necrotic soft tissue. The reconstructed arteries showed good perfusion to the new free flaps until union of the tibias occurred. The patients were followed-up for 21 years and 17 years postoperatively, respectively. In management of open comminuted fracture of the tibia, injury of the arterial system must be ruled out by angiography in addition to evaluation of the degree of soft tissue injury.

OBJECTIVETo explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.

METHODSSix fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed. Based on the anatomic study, the perforator flaps were designed to reconstruct soft tissue defects at dorsum of hands and wrists. The redundant fat on the flaps was removed, but preserving the nutrient vascular system. 11 flaps were used with the size ranging from 2 cm x 5 cm to 10 cm x 14 cm.

RESULTS43 skin perforators of posterior tibial artery were observed in six lower limbs, 29 perforators with the outer diameter is greater than 0.5 mm when they threading over the deep fascia plane, on average every 4.8 bundles of sides. The mean outside diameter of perforating artery is (1.8 +/- 0.5) mm, and the length is (44 +/- 15) mm. 6 perforators were founded both in the second and fifth zone which could be used for anastomosis for its better diameters. All flaps survived completely without any complication at donor sites. 7 cases were followed up for 3-12 months. Both satisfactory functional and cosmetic results were achieved with a soft and thinned appearance.

CONCLUSIONSThe thinned posterior tibial artery free perforator flap has a reliable blood supply and good appearance. It is very suitable for the reconstruction of small or medium-sized defects at the dorsum of hands and wrists.

OBJECTIVETo present the methods of vacuum sealing drainage and free coupling chain-link flap of posterior tibial artery flap and medial plantar flap in the reconstruction of degloving injury of propodium.

METHODSFrom Oct. 2008 to Dec. 2011 five cases with degloving injury of propodium underwent debridement and vacuum sealing drainage on the first stage. Free chain-link flap of posterior tibial artery flap and medial plantar flap were applied to close the wound at the secondary stage. The nerve was included in the coupling flaps. The size of posterior tibial artery flap ranged from 14 cm x 10 cm to 11 cm x 8 cm,and the size of medial plantar flap ranged from 12 cm x 8 cm to 8 cm x 6 cm.

RESULTSAll flaps were survived with no vascular crisis. The flap sensation recovered to S3-S3 during the follow-up period of 6-21 months. The texture and appearance of flaps were satisfied. The plantar had not ulcer and corpus callosum.

CONCLUSIONVacuum sealing drainage and free chain-link flap of posterior tibial artery flap and medial plantar flap with nerve are the ideal methods for the reconstruction of degloving injury of propodium.

OBJECTIVETo investigate the applied anatomy of the superficial peroneal artery perforator flap and report the clinical results of repairing the soft tissue defects with free perforator flaps.

METHODS15 fresh cadavers were injected with a modified lead oxide-gelatin mixture for three-dimensional visualization reconstruction using a 16-slice spiral computed tomography scanner and specialized software (Materiaise's interactive medical image control system, MIMICS). The origin, course and distribution of the superficial peroneal artery perforator in the anterolateral leg region were observed. Clinically 6 cases with hand defects and 6 cases with feet defects were treated with free superficial peroneal artery perforator flap transplantation. The defect size ranged from 3.0 cm x 4.5 cm to 5.0 cm x 11.0 cm.

RESULTSThe diameter of the superficial peroneal artery is (1.2 +/- 0.3) mm at its origin from the anterior tibial artery 5 cm below the fibula head. It is (5.6 +/- 1.8) cm in length. This artery is truly anastomosed with other perforators to form the chain of superficial peroneal nerve accessory artery. The superficial peroneal artery perforators [outer diameter (0.7 +/- 0.2) mm] with a vein are in the anterolateral leg region, supplying the skin in proximal-middle region. All the 12 cases were treated successfully. The clinical results were satisfactory after 3-12 months of following-up.

CONCLUSIONSThe superficial peroneal artery perforator flap has constantly, reliable blood supply, and good texture. It is a good option for repairing soft-tissue defect with free transfer.

A 48-year-old man sustained a traffic accident injury to his left leg. It was an open fracture of the left tibia and fibula accompanied by a large soft tissue defect (27 cm multiply 7 cm). Doppler examination revealed the posterior tibial artery was occluded due to thrombosis. Three weeks after injury, the latissimus dors myocutaneous flap was elevated with a T-shaped vascular pedicle and was interposed between the two vascular ends of the posterior tibial vessel of the contralateral leg. Two end to end anastomoses were performed between the two vascular ends of the posterior tibial vessel of the contralateral leg and the latissimus dors myocutaneous flap's T-shaped vascular pedicle. The latissimus dorsi myocutaneous flap was used for repair of a large soft tissue defect of the left leg. The vascular pedicle was cut off after 28 days and the flap survived completely. After 3-years'follow-up postoperatively, a good contour was confirmed at the recipient area. The right tibia and fibula fractures were confirmed healing radiologically. The posterior tibial artery of contralateral leg was demonstrated patent by clinical and Doppler examinations.
