Abstract
OBJECTIVE This study was performed to explore the treatment of the injury caused by traumatic limb amputation. METHODS From October 2002 to October 2021, 30 cases were enrolled in the present study. The reasons for injury were as follows: 8 cases with single hydraulic column crush injury, 12 cases with gear and wire rope stranding, 6 cases with belt avulsion injury, and 4 cases with carbon block smash injury. The present study application of a free or small saphenous vein bypass to reconstruct the injured artery and vein according to the concept of the angiosome model. The defective vessels were bridged with the axial vessels of a flow-through flap, such as a medial calf flap or anterolateral femoral flap, to construct an additional blood supply and drainage vein for the severed limb. The clinical data of 30 cases with traumatic limb amputation of the lower leg and ankle were retrospectively analyzed. RESULTS In all 30 cases of traumatic limb amputation, the replantation via the adoption of a flow-through flap was successful, and 85.6% of the patients remained in good postoperative condition. There were no symptoms of ischemia in the marginal segment after blood supply reconstruction of the transected limb by axial vascular bridging within the flap. CONCLUSION Via the adoption of microsurgical techniques, the blood supply to the transected limb can be reconstructed by bridging the defective vessels with the adoption of the axial vessels of the flow-through flap is a feasible and advanced treatment option.

[PMID: 38803926 PMCID: PMC11128512 DOI: 10.1016/j.heliyon.2024.e31179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 05/08/2024] [Accepted: 05/12/2024] [Indexed: 05/29/2024] Open
Abstract
Objective Management of large irregular wounds in children had been confusing plastic and reconstructive surgeons. Herein, this study was aimed to propose a new treatment method based on the principle of adapting different recipient zones to overcome the intractable wounds, simplifying and programing the design process of targeted flaps for covering large irregular soft-tissue defects. Patients and methods From January 2009 to December 2020, 31 children (9 girls and 22 boys) aged 3-16 years (mean 9.8 years) underwent multiple modular flaps with edge to edge splicing reconstruction of the lower extremities. All the wounds were large with non-adjacent defects and with or without a dead space. Several variants of flaps were harvested according to the needs and reconstruction requirements of patients. Results A total of 71 flaps were harvested from 31 patients and all flaps donor sites received primary closure. Nine patients underwent split-thickness skin grafting, and three cases of flaps survived from vascular crisis by rebuilding the vessels and the rest accepting LD flap transplants. And five partial necrosis of the distal epidermis flaps recovered using skin grafting and dressing change. No major complication was encountered in other patients and donor sites, except one heel ulcer. During the follow-up (ranging from 16 to 38 months, mean 27.7 months), aesthetic and functional results of reconstructed limbs were satisfactory in all patients. Conclusions The Individualized design program of multiple flaps for adapting different recipient zones is an alternative for repairing large irregular soft-tissue defects in children, beneficial for plastic and reconstructive surgeons to simplify and program the process of designing and perform multiple flaps to achieve this goal. Level of evidence III, Retrospective.

Abstract
ABSTRACT The management of critical limb trauma is challenging because limb salvage is preferable to amputation. For upper limb reconstruction, the surgical restoration of functionality, and appearance, a multidisciplinary approach is needed. We report the case of an extensive composite tissue defect of the forearm caused by a machine-crushing injury that was repaired by a flow-through chimeric anterolateral thigh flap with a vascularized fibular graft. Reconstruction was performed as a single-stage procedure; no complications occurred, and both functional and aesthetic outcomes were satisfactory.

J Plast Reconstr Aesthet Surg 2023; 84:505-513. [PMID: 37418849 DOI: 10.1016/j.bjps.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 04/25/2023] [Accepted: 06/05/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND Multi-territory perforator flaps have become the preferred option for the repair and reconstruction of large soft tissue defects. Although methods (e.g., pharmacological agents, mechanical stimulation, and thermal stimulation) were developed to open choke vessels to improve flap survival, the flap necrosis rate is still as high as 28.8%. The authors hypothesized that high-pressure infusion might enhance flap viability by dilating choke arteries intraoperatively in a rat model of multi-territory perforator flap. METHODS Two-month-old male Sprague-Dawley rats were randomized into two groups (n = 32 each). During the multi-territory perforator flap elevation based on the right superficial epigastric angiosome, one group received continuous high-pressure infusion (mean pressure, 250 mmHg; duration, 1 min) of an isotonic heparin sodium solution (12,500 U/L) via the artery in the pedicle, whereas the other group received no infusion. At 7 days postoperatively, arteriography was performed; endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) expression and microvascular density were evaluated by western blot and histology, respectively; and flap survival was compared. Moreover, intraluminal diameters were examined at 1 day and 7 days postoperatively using hematoxylin and eosin staining, and coagulation function was assessed immediately postoperatively. RESULTS High-pressure infusion significantly promoted the dilation of choke arteries at 1 day and 7 days postoperatively. It also increased eNOS and VEGF expression, flap survival, and microvascular density. The coagulation function remained unaffected. CONCLUSIONS High-pressure infusion allowed intraoperative and postoperative dilation of the choke arteries that enhanced the viability of multi-territory perforator flaps in rats.

Abstract
BACKGROUND This study aims to describe the application of a modified St. Thomas' solution in patients with severe limb injuries.
CASE SUMMARY Four patients who sustained a high-energy trauma and underwent complete upper limb amputation were pretreated with a modified St. Thomas' solution before upper limb replantation. After the perfusion solution stopped flowing from the blood vessel, the amputated upper limb amputation was replanted. The patients were instructed to perform functional rehabilitation training after the operation. All 4 patients were followed up for 5 years. All the severed upper limbs survived. Routine re-examination after the operation showed that the function of the affected limb was restored. All the patients were satisfied with the sensory and functional recovery of the affected limb.
CONCLUSION The modified St. Thomas' solution can effectively improve the success rate of limb salvage surgery and the recovery of limb function in patients with a severe limb injury.

Abstract
Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

Abstract
OBJECTIVE To investigate the effectiveness of the modified great toe fibular flap using the distal artery pedicle as reflux vein for repairing distal phalanx finger wound. METHODS Between June 2018 and January 2020, 15 patients who suffered tissue defect of the distal phalanx finger were treated, including 12 males and 3 females, the average age was 40.2 years (range, 24-56 years). All of them were caused by machine crush injury. There were 2 cases of thumb, 6 cases of index finger, 3 cases of middle finger, 3 cases of ring finger, and 1 case of little finger. The defects ranged from 1.7 cm×1.3 cm to 3.0 cm×2.0 cm. The time from injury to admission was 0.6-4 hours, with an average of 2.3 hours. The medial fibular proper digital artery was further dissociated to the distal end and anastomosed with the recipient vein as the reflux vein. The area of flaps ranged from 2.0 cm×1.5 cm to 3.2 cm×2.2 cm. RESULTS All the flaps survived without vascular crisis, and the wounds healed by first intention. Except for 1 case that the suture was too tight, the incision was partially split after the stitches were removed, and it healed spontaneously after dressing change, the other patients had good healing of the donor site incision and normal foot function. All 15 patients were followed up 3-18 months, with an average of 9.3 months. The appearance of finger pulps were satisfactory with full and threaded. The color, texture, and elasticity of the flaps were good, and the two-point discrimination was 6-8 mm at last follow-up. The flexion and extension of fingers were normal. At last follow-up, hand function was evaluated according to the upper limb function evaluation trial standard of the Chinese Medical Association Hand Surgery Society, and the results were 13 cases of excellent and 2 cases of good. CONCLUSION Modified great toe fibular flap using the distal arterial pedicle as a reflux vein can improve the venous drainage of the flap and contribute to increase the success rate of the flap without additional injury.

A neglected problem in the utilization of free anterolateral thigh flap toward reconstructing complicated wounds of extremities: the obliteration of deep dead space. J Orthop Surg Res 2020; 15:483. [PMID: 33087149 PMCID: PMC7579970 DOI: 10.1186/s13018-020-01914-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Accepted: 08/24/2020] [Indexed: 11/10/2022] Open
Abstract
Background Deep dead space may be thought as an independent risk factor of the poor infection control after flap reconstruction in complex limb wounds. But it can be easily neglected. The conventional skin flap and musculocutaneous flap are difficult to obliterate the deep dead space in irregular shape effectively. It was investigated that the clinical application of chimeric anterolateral thigh perforator flap in the treatment of complex wounds complicated with deep dead space of the extremities in the paper. Methods Fifty-six cases complicated with deep dead space wounds were registered in group. Following thorough debridement and treatment with VSD, the granulation tissues grew with well-controlled infection. And then the chimeric anterolateral thigh perforator flap was used to obliterate the deep dead space and repair the wounds. The postoperative flap survival and infection conditions were evaluated. Results Overall, the infection was effectively controlled, without persistent exudation or sinus tract formation after wound healing. While 5 cases lost to follow-up, the remaining 51 cases were followed up until 15 months on average. Generally, the affected extremities recovered satisfactorily with normal appearances and texture of the flaps, along with normal functions. Importantly, no recurrence of infection was observed. Conclusion During the grafting of chimeric perforator flap pedicled with lateral thigh muscle flap, the muscle flap is recommended to obliterate the deep dead space while the skin flap is being used to cover the wound. The combination of these two technologies performed well in the repair and reconstruction of the complex wounds of the extremities, possessing potential for broader clinical application.
