Impact of multidisciplinary management via special clinic for the outcome of diabetic foot disease: A prospective observational study.

Introduction: Diabetic foot is a common complication of diabetes mellitus, affecting approximately 15-20% of individuals with diabetes. It is a comorbid condition that significantly impacts the routine life of patients. This study aimed to assess multidisciplinary management strategies and their impact on the outcomes of patients with diabetic foot. Methods: A prospective observational study was conducted on 56 patients with diabetic foot. Outcome measures included the type of surgery, frequency of surgery, morbidity, mortality, patient satisfaction, return to work, and the number of patients using prostheses. Results: The majority of the patients (87%) received surgical treatment. The most common type of surgery performed was debridement (55%), followed by minor amputations (toes amputation/forefoot amputation) (28%) and major amputations (below-knee (B/K) or above-knee (A/K)) (15%). More than 70% of patients had multiple surgeries. The mortality rate was low (7%), and 71% of surviving patients were satisfied with their treatment. Sixty-seven percent of patients had an early return to work. The number of patients using prostheses was also high (73% of major amputation cases). Conclusion: Multidisciplinary management is the most effective approach for diabetic foot patients. These patients may experience less morbidity and an early return to work. A specialized care clinic for diabetic foot patients is essential to prevent treatment failure, loss of follow-up records, permanent limb loss, and economic burdens on society.

Free Flap Monitoring Using Infrared Thermography: An Objective Adjunct to Clinical Monitoring.

Background Early detection of free flap compromise is critical for salvage of the flap. Various methods of free flap monitoring have been described, but clinical assessment is the standard method for among all. In this study, role of infrared thermography is evaluated for free flap monitoring. Materials and Methods In patients undergoing free flap surgery, monitoring was done using standard clinical parameters and infrared thermography as per our institutional protocol. Mean temperature difference (∆T) between the flap and the surrounding skin was calculated using the temperature readings from the thermal images intra- and postoperatively. The accuracy of infrared thermography in flap monitoring was assessed in comparison to the standard clinical protocol. Results Forty-one flaps were included in the analysis, out of which five flaps got compromised. It was observed that the mean temperature difference was higher (mean ∆T 0.20-0.59 vs. 2.38-3.32) when there was a flap compromise, and this temperature difference was evident even before the development of clinical signs. The temperature difference in venous thrombosis (mean ∆T 1.0-2.7) was found to be slightly lower than in arterial insufficiency (mean ∆T 2.1-4.4). For a ∆T cutoff value of 2°C, the thermal camera had a sensitivity of 88.6%, specificity of 98.9%, positive predictive value of 93.9%, and negative predictive value of 97.7%. Conclusion Infrared thermography is a valuable and noninvasive objective tool in free flap monitoring, which can detect flap compromise (increasing value of ∆T) even before it becomes clinically evident.

Dorsal Carpal Artery Perforator Flaps: An Anatomical and Clinical Study.

BACKGROUND: Hand injuries pose challenges due to complexity and aesthetic-functional concerns. Dorsum of hand injuries are difficult to treat due to thin skin cover and increased propensity to exposure of underlying structures. Perforator-based flaps can provide better outcomes with minimal donor site morbidity. This study aims to bridge the gap in anatomical knowledge and explore the potential benefits of dorsal carpal artery perforator flap. MATERIALS AND METHODS: A prospective study was done from July 2021 to June 2023, focused on study of dorsal carpal artery perforators on 12 fresh frozen cadaveric hands. Anatomical study involved injection of red latex into arteries at the wrist, followed by dissection and measurements. During the clinical phase, we used the inferences gained from the anatomical study to identify and mark perforator of dorsal carpal arteries. We performed V-Y advancement flap based on the DCPs in 5 patients who had dorsum of hand defects due to trauma. RESULTS: The study was carried out on 6 fresh frozen cadavers (12 hands). Anatomical findings revealed the anatomical location, caliber, and consistent number of dorsal carpal artery perforators supplying the dorsum of the hand arranged in 2 rows. Clinically, we applied this insight to create V-Y flaps in 5 patients with successful outcomes, thus, offering DCP-based flap as an alternative to distant flaps. CONCLUSION: DCP-based flaps offer an efficient solution for reconstructing proximal hand defects over the dorsum, with minimal complications, enhancing our understanding of hand reconstruction options. The study's comprehensive anatomical insights and clinical outcomes contribute to improving hand defect management and surgical techniques.

Propeller vs. free fasciocutaneous flap in reconstruction of complex lower limb defects-A prospective study.

BACKGROUND: Of all body regions, lower extremity wounds have been and remain the greatest challenge. Free flaps have been accepted as a reasonable option to solve this dilemma, but they require the complexity of microsurgery. This study aimed to compare the postoperative and clinical outcomes of propeller flap and fasciocutaneous free flap in the reconstruction of complex lower limb defects. MATERIALS AND METHODS: This randomized controlled trial was conducted from July 2021 to June 2023. Selected patients were randomized into two groups: the propeller flap group and fasciocutaneous free flap group. Demographic data, preoperative parameters, and postoperative parameter, including esthetic analysis, scar assessment, neurosensory analysis, psychosocial analysis, and lower extremity function, were estimated and statistically significant compared between the two study groups. RESULTS: Road traffic accident (73.3%) was the most common etiology for lower limb defects in both groups. The foot and lower third of the leg were the most common site of defect, constituting 79.99%. The duration of surgery was significantly shorter in propeller flap as compared to fasciocutaneous free flaps. Flap size was smaller, with better neurosensory improvements in propeller flap group. Esthetic analysis, scar assessment, psychosocial analysis, and lower extremity functional analysis yielded similar results in both study groups. CONCLUSION: Propeller flap has better outcomes compared to free flap in terms of smaller size of flap, shorter duration of surgery, and reduced length of hospital stay. Comparable results were obtained with respect to esthetic score, scar assessment score, psychosocial analysis, and neurosensory recovery and lower extremity functional score.

Efficacy of novel, three jaw adventitia holding microclamps compared to Acland microclamps in patients undergoing end-to-end microvascular anastomosis: A randomized control trial.

OBJECTIVE: To evaluate the efficacy of three jaw adventitia holding (TADH) microclamps in end-to-end microvascular anastomosis. BACKGROUND: Acland clamps, though highly efficacious, require a steep learning curve and are associated with complications such as back walling and incomplete bites. METHODS: A single center, parallel group, 30-patient randomized clinical trial was conducted with a 1:1 allocation ratio in Acland and TADH microclamp groups. Primary outcome was time taken for microvascular anastomosis in terms of arterial and venous clamping and suturing time. Secondary outcomes included ease of use, need for clamp flipping and adventitia trimming, and need for assistance and flap survival. RESULTS: TADH microclamps were found to be beneficial when compared to Acland microclamps in end-to-end microvascular anastomosis, in terms of artery clamp time (19.07 ± 3.751 min, 95% CI 10.058-17.942, p < 0.001), artery suture time (15.87 ± 3.357 min, 95% CI 10.660-17.206, p < 0.001), vein clamp time (21.50 ± 3.849 min, 95% CI 12.131-19.469, p < 0.001), and vein suture time (16.58 ± 3.147 min, 95% CI 13.232-20.368, p < 0.001). The TADH microclamps did not require flipping to enable suturing of the posterior walls of the vessel. Statistically significant difference was found in surgeon-reported ease of use with TADH microclamps (Chi-square value 9.867, p < 0.001). Statistically significant difference was found in relation to the need for assistance with TADH microclamps (Chi-square value 19.286, p < 0.001). CONCLUSION: This study found TADH microclamps to be faster, easier to use, and clinically efficacious in reducing the anastomosis time compared to those of the Acland clamps.

A novel, innovative clamp with vessel eversion feature for end-to-end microvascular anastomosis.

In the era of technological advancement, the practice of microsurgery has virtually remained unchanged for the last few decades. In this article, the authors describe innovative three jaw microsurgery clamps which provide a novel vessel eversion feature. The advantages of these clamps include better visibility of the posterior wall resulting in lower incidence of back walling and incomplete bites. These clamps also eliminate the need to flip the clamps as a result of better posterior wall visualisation. These unique microsurgery clamps not only ease the arduous, technique sensitive field of microsurgery in the operating room, but can also serve as a tool for the training of future reconstructive surgeons, thereby reducing the steep learning curve considerably.

A Prospective Trial Comparing Outcomes at 11 Months of a Standard Cross-Finger Flap versus a Laterally Based Thenar Flap for Fingertip Reconstruction.

Background: The standard cross-finger flap (CFF) and laterally based thenar flap (LTF) are the time-tested modalities of fingertip reconstruction. We were unable to find any studies that have compared these two flaps for fingertip reconstruction. The aim of this study is compare the outcomes of these two flaps at 11 months after fingertip reconstruction. Methods: This is a prospective study of 40 patients with fingertip amputation who underwent reconstruction with either a standard CFF or an LTF. Data with regards to the patient, the injury, treatment and complications were recorded. Patients were followed up weekly for the first 6 weeks and at 3, 6, 9 and 12 months thereafter. Outcome measures assessed at final follow-up included passive range of motion, two-point discrimination, cold intolerance, patient aesthetic satisfaction with the flap, assessment of donor scar and psychosocial benefit. Results: Fingertip reconstruction was done with 23 CFFs and 17 thenar flaps. Partial necrosis was noted in three thenar flaps. The mean follow-up period was 11 months. The sensory recovery and aesthetic satisfaction with the flap were greater in thenar flap group. There were no differences between the two flaps in the other outcome measures. Conclusions: Sensory recovery and aesthetic outcomes were better in thenar flaps compared to a CFF. However, thenar flap were associated with a greater incidence of partial flap loss. Level of Evidence: Level III (Therapeutic).

Fingertip Amputation Reconstruction with VY Advancement Flap: Literature Review and Comparative Analysis of Atasoy and Kutler Flaps.

BACKGROUND: Many different flaps had been described to cover exposed bone in fingertip amputations and injuries. The variants of VY advancement flap, by far the simplest, had proven to render good functional and aesthetic outcome. We aimed to revisit and compare the various VY advancement flaps in fingertip reconstruction. METHODS: PubMed [MEDLINE] database was searched for VY advancement flap in fingertip reconstruction. Demographic and outcome data were extracted from relevant studies and comparative analysis was made. Patients with fingertip amputations undergoing reconstruction by either Kutler of Atasoy flaps in our institute, were assessed for sensory recovery, cold intolerance, joint's range of motion, and aesthetic outcomes and results were analysed. RESULTS: Among the 744 articles, 32 citations went full text review and were included, while data of 13 articles were tabulated. Weighted mean of 2PD in Kutler and Atasoy estimated to be 6 and 7.5 mm respectively. Hook nail deformity was in 29% and 35%, pain was present in 71% and 30% patients, in Kutler and Atasoy flaps respectively. Forty fingertips with Allen type II/III were reconstructed. Sensory outcomes of Atasoy flap and Kutler flaps were better than the previous study results. Four patients had cold intolerance. All patients achieved satisfactory aesthetic outcome. CONCLUSION: Over time, VY advancement flap have been successfully used for reconstruction of Allen type II-IV fingertip amputations, as suggested by the good sensory, functional and aesthetic outcomes.

Isolated Chest Wall Necrotizing Fasciitis: An Unusual Fatal Manifestation of Extrapulmonary Tuberculosis.

Primary tuberculosis of the chest wall is a rare disease and very difficult to diagnose without clinical suspicion. Here, we present an unusual case of necrotizing fasciitis due to an aggressive form of chest wall tuberculosis. A 22-year-old male presented in emergency with acute-onset swelling and redness over the right side of the neck and chest wall. He had no history of any drug reaction, trauma, and unknown bite. The patient underwent aggressive debridement followed by split-thickness graft under intensive care monitoring. Radiological imaging and Ziehl-Neelsen (ZN) staining of pleural fluid revealed no evidence of pulmonary tuberculosis. Special investigations such as cartridge-based nucleic acid amplification test and ZN staining from pathological skin or subcutaneous tissue revealed active tuberculosis; therefore, anti-tubercular drugs were started.

Angiomyxolipoma: a rare variant over the forehead.

Lipoma is a common benign mesenchymal tumour. However, angiomyxolipoma (AML) is one of its rarer variants. It was first described by Mai et al in 1996 in the lipomatous lesions having mature adipocytes in a myxoid background with rich vascular network. We present the case of a 21 year-old man with recurrent forehead swelling diagnosed as AML on microscopy. It is important to document this rare variant to add to the limited literature and to aid in differentiating it from its malignant counterpart. Moreover, as our case presented with recurrence within a short period of time, a precise diagnosis and documentation of recurrence is essential as it is reportedly the first case with recurrence among the 21 cases of AMLs previously published.

Finger pulp reconstruction with thenar flap: Aesthetic and functional outcome.

PURPOSE: Fingertip injuries are common in industrial production activities as well as in domestic work. Loss of pulp hampers daily life activities. Functional and aesthetic aspects are important in fingertip reconstruction. The bone is usually exposed along with soft tissue loss. Therefore to reconstruct the pulp flap with adequate bulk is required. METHODS: We reported a case series of 12 patients with the injury over the volar aspect of distal phalanx of the index or middle finger. In all cases, laterally based thenar flap was chosen. The flap donor site was closed primarily in most of cases, while 4 patients required skin graft. The flap was detached between 2-3 weeks. Functional assessment was done using static and dynamic 2-point discrimination and range of motion at each joint. The aesthetic outcome was assessed through questionnaire. The results were analyzed using the unpaired t-test (SPSS version 21). RESULTS: Partial necrosis occurred in 2 cases while rest of flaps survived successfully. Static 2-point discrimination ranged from 6-10 mm, mean 8.6 mm; and dynamic 2-point discrimination ranged from 8-10 mm, mean 8.9 mm. The mean satisfaction score was (4.0 ± 0.55). CONCLUSION: Thenar flap is a good choice for reconstruction of the finger pulp as it provides the bulk with good functional and aesthetic outcome.

Two-staged reverse sural flap: a versatile flap with consistent results in the soft tissue reconstruction of distal leg and heel defects-an institutional experience.

BACKGROUND: Reverse sural flap (RSF) is commonly used for soft tissue reconstruction of distal leg and heel defects. The classic method of flap transfer is the single-staged cutaneous islanded reverse sural flap (SS-RSF). This method is associated with variable flap complications notably the venous congestion. The other form of flap transfer is the two-stage reverse sural flap (TS-RSF), in which the pedicle of the flap is exteriorized in the first stage. Flap division and re-inset are done in the second stage. The aim of this paper is to review the flap outcomes and complications among the SS-RSF and TS-RSF reconstruction of soft tissue defects in the distal leg and heel. METHODS: This is a retrospective chart review of RSF being operated in a tertiary care hospital. The duration of study was 1.5 years. Twelve RSFs (6 SS-RSF, 6 TS-RSF) were done for soft tissue defects in the distal leg and heel. Wounds of various etiologies (traumatic, chronic, non-healing ulcers) were reviewed. Trauma was the most common etiology with 8 out of 12 (66.7%) patients. Large wounds, donor site damage and patients with peripheral vascular disease were excluded from the study. RESULTS: Five out of six (83.3%) of TS-RSF healed uneventfully. However, 3 out of 6 (50%) of SS-RSF had partial flap necrosis. All complicated flaps healed well subsequently. No donor site complication was found in any of our patients. CONCLUSION: Pedicle exteriorization in TS-RSF eliminates the element of venous congestion and eventually flaps necrosis. Less technical expertise and minimal morbidity are additional advantages of TS-RSF. LEVEL OF EVIDENCE: Level IV, therapeutic study.
