Comparison of neuraxial acoustic target window of the spine among rider sitting, cross leg, hamstring stretch, and classical sitting position: An observational study.

Background and Aims: To compare ultra-sonographic dimensions of acoustic target window of the spine in the participants at four different sitting positions namely cross leg sitting (CLP), hamstring stretch (HSP), classical sitting (CSP) and riders sitting position (RSP). The primary objective of this study was to measure the neuraxial acoustic target window (defined as interlaminar distance between L3-L4 lamina). The secondary objective was to compare ultra-sonographic measurements of the depth of ligamentum flavum from the skin, and to compare the diameter of intrathecal space and comfort score in the four different sitting positions. Material and Methods: This study is a prospective observational study. Eighty participants were included and positioned in four different sitting positions to perform an ultra-sonographic scan and measure various parameters of the acoustic neuraxial window. The interlaminar distance, the distance of skin from the ligamentum flavum, and the diameter of the spinal canal or intrathecal space was measured in the L3-L4 intervertebral space in different positions. Results: The mean value of interlaminar distance among four sitting positions was ranging from 1.40 cm to 1.44 cm (P value 0.725.) The distance of ligamentum flavum from skin and diameter of intrathecal space was also comparable in all the groups. The comfort score in CSP was significantly better when compared to other groups with a median score of 4 (P value < 0.001). Conclusions: There is no statistically significant difference in interlaminar distance in various sitting positions. All four positions are equally effective and can be used as an alternative to spinal/epidural intervention, but the CSP came out to be the most comfortable and more emphasis should be given to the comfort as it increases the chance of success rate of the procedure.

Innervated vastus lateralis muscle: complementing and completing the anterolateral thigh flap for abdominal wall reconstruction.

Reconstruction of composite abdominal wall defects is challenging. An anterolateral thigh (ALT) flap has established itself in the algorithm for abdominal wall reconstruction. Augmenting innervated vastus lateralis (iVL) muscle to ALT has added advantages. We describe previously unreported advantage of ALT with iVL.A woman in her 30s, suffering from Mullerian adenocarcinoma with metastasis to the right anterior abdominal wall and right inguinal lymph node, was taken for wide local excision and reconstruction. After excision, there was a 15×12 cm defect of the anterior abdominal wall. We reconstructed the defect with prosthetic mesh and pedicled composite ALT and iVL. There was venous congestion in the ALT flap and it could not be salvaged. We debrided the ALT flap and applied split skin graft over iVL. The grafted and donor sites healed well. The patient was able to do moderate strenuous activities. The presence of iVL allowed us to get away with minor procedure and averted the need for another flap.

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.

Heterotopic Ossification After Reconstruction with Free Fibula Flap - an Ambiguous Mishap.

Heterotopic ossifications (HO) are rare, yet, well reported complications after free flap transfer. We present a case of HO that occurred within a month, and has not been previously described in the literature. This serves as a reminder that bony hard swellings proximal to the free flap within a month should raise the suspicion of HO.

The Colossal Mandibular Ameloblastoma: Surgical Challenges and Current Perspectives of Management.

Ameloblastoma is the most common aggressive benign odontogenic tumour of the jaws. Ameloblastoma is a benign epithelial odontogenic tumour that typically arises in the mandible or maxilla. A clinical, radiographic and histopathological report is presented of a case of giant acanthomatous ameloblastoma in the left hemi mandible of a 46-year-old healthy lady. The histopathological examination of the removed specimen revealed the histopathological pattern of an acanthomatous ameloblastoma. The radiographic appearance of the lesion showed the presence of multilocular radiolucencies, which were crossing the midline, which is rarely found in ameloblastoma. Due to its rarity and lack of data, we take this opportunity to present a case of advanced acanthomatous ameloblastoma and its surgical challenges.

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.

Comparison of Binaural Tone Music vs Patient Choice Music vs Midazolam on Perioperative Anxiety in Patients Posted for Surgery Under Spinal Anaesthesia: a Randomized Control Trial.

Background Perioperative anxiety affects patients' hemodynamics by increasing stress levels, leading to delayed recovery. In this study, we compared the anxiety-reducing effect of music (patient choice and binaural tone music) with midazolam for perioperative anxiolysis in patients undergoing surgery under spinal anaesthesia. Methods After obtaining institutional ethical clearance and informed written consent, a total of 225 patients classified as ASA grades 1 and 2 (American Society of Anesthesiologists) were enrolled and randomised into three groups of 75 patients per group. Group A patients received research-selected music (binaural tone) via noise-cancelling headphones, Group B received intravenous midazolam (minimum of 1 mg to 2 mg maximum) as per clinical judgement, and Group C participants provided patient-preferred music via noise-cancelling headphones. The patient's perioperative anxiety was assessed using a visual analogue anxiety scale at regular time intervals. Results Anxiety scores were significantly reduced in the patient's choice music group (Group C) and binaural tone music group (Group A) as compared to the midazolam group (Group B). Postoperative pain scores were statistically significantly lower in Group C, followed by Group A and Group B. On comparing patient satisfaction scores, using numerical rating scores, 96% of patients in Group C achieved excellent scores with a p-value of 0.007. Conclusion Binaural tone music and patient choice music can be suitable alternatives to pharmacological therapies for perioperative anxiolysis.

Dynamic correction of ulnar claw hand deformity with a simple insertion into the lumbrical muscle.

Numerous methods of tendon transfers are available to correct claw hand deformity. In this article, we describe a simple insertion of the transferred flexor digitorum superficialis tendon, into the lumbrical muscle and proximal tendon. Sixty patients underwent surgery for claw hand correction. These were equally divided into three groups undergoing; modified Stiles Bunnell procedure; 'lasso' insertion into A1 pulley and the lumbrical insertion procedure. Evaluation was done with proximal interphalangeal joint angle measurements, grip strength and using the Brand's criteria, 1 year after surgery. The improvements were comparable among the three groups. Insertion into the lateral bands has been a standard method of claw correction. In addition to correcting the hyperextension of the metacarpophalangeal joint, it transmits force for interphalangeal joint extension and restores the sequence of flexion of fingers, thus making the grasp effective. Insertion into the lumbrical muscle belly and proximal tendon shows similar results. It can be performed via a single incision in the palm, reducing operative time.

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.

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.
