Reproducibility of pop sensation, Thompson sign in achillotomy, and final Pirani score to predict clubfoot relapse: Achillotomy clinical signs and Pirani predictive ability.

Ultrasound (US) can guide and confirm percutaneous release of the achilles tendon in the clubfoot. However, this technique may not always be available; therefore, surgeons' reported feelings of tendon release ("click" or "pop") and the Thompson sign could demonstrate that they are sensitive and reliable for confirming complete tendon release. The purpose of this study was to compare the reproducibility of clinical maneuvers that aim to detect the reported "click" or "pop" sensation by the surgeon and the Thompson sign after surgical release in percutaneous achilles tenotomy compare with US in patients with clubfoot. A cross-sectional reproducibility study of consecutive patients with idiopathic clubfoot was conducted. All the patients were scheduled to undergo tenotomy in the operating room using the standard percutaneous achilles tenotomy technique under sedation. The surgeon's reported surgical sensation ("click" or "pop") and Thompson signs were compared to the US assessment of the cut. The final Pirani score was used to predict recurrence risk and was correlated with the number of plaster casts and age. Forty-five feet were affected in 30 patients. Eighteen (60%) men. Age range: 1 to 60 months. The sensation of "click" or "pop" was recorded in 38 patients, and complete release was confirmed by US in 37 patients, for a sensitivity (Se) of 0.95 and specificity (Sp) of 0.63. Thompson signs were positive in 33 and 36 patients at 2 evaluations, with Se values of 0.87 and 0.92 and Sp values of 0.88 and 0.75, respectively. The Pirani final score, a predictor of recurrence risk, had an area under the curve of 0.80 (95% CI = 0.63-0.97; P = .005), Se = 0.78, and Sp = 0.56, with a cutoff point of 2.75. The feeling of achilles tendon release and Thompson sign had high sensitivity, prevalence, accuracy, and posttest probability. The confirmation of tendon release based on clinical signs could prevent the use of US.

Easy and Safe Clamping of the Internal Jugular Vein and Internal Carotid Artery for End-to-Side Anastomosis in the Vessel-Depleted Neck.

BACKGROUND: Damage to the vascular system resulting from radiotherapy and previous surgeries in patients with recurrent neck tumors has a negative impact on secondary reconstructions. In this study, we describe a simple method for occlusion of the great vessels of the neck in patients with difficult access to recipient vessels for anastomosis. METHODS: A 1 or 0 gauge silk ligature is placed at a circumference of 540 degrees around the vessel, holding the base of the suture with a fine hemostatic clamp exerting sufficient pressure to stop the blood flow in the vessel (internal carotid artery or internal jugular vein), to prepare the end-to-side anastomosis to the flap. RESULTS: From 90 head a neck reconstructions for oncologic patients using microvascular flaps performed between April 2011 and April 2021, 8 of them (8.8%) were performed in patients with multiple previous surgeries and/or radiotherapy, with lesion of the arterial thyrolyngopharyngofacial trunk and secondary recipient veins, being the internal carotid and internal jugular the only available recipient vessels in the neck. CONCLUSIONS: Occlusion of the great vessels of the neck with a thick silk at 540 degrees held by a hemostatic clamp at its base is a safe and reproducible method for occlusion of these vessels to perform end-to-side anastomosis in patients with difficult vascular access in the neck without increasing the risk of endothelial damage and thrombosis from the anastomosis.

Closed reduction evaluation in dysplastic hip with the Ömeroglu system in children aged 24 to 36 months.

Closed reduction (CR) as an initial treatment for developmental hip dysplasia of the hip (DDH) in children aged 24 to 36 months is debatable; however, it could have better results than open reduction (OR) or osteotomies, because it is minimally invasive. The purpose of this study was to evaluate the radiological results in children (24-36 months) with DDH initially treated with CR. Initial, subsequent, final anteroposterior pelvic radiological records were retrospectively analyzed. The International Hip Dysplasia Institute was used to classify the initial dislocations. To evaluate the final radiological results after CR (initial treatment) or additional treatment (CR failed), the Ömeroglu system was used (6 points excellent, 5 good, 4 fair-plus, 3 fair-minus, and ≤2 poor). The degree of acetabular dysplasia was estimated using the initial acetabular index and the final acetabular index, Buchholz-Ogden classification was used to measure avascular necrosis (AVN). A total of 98 radiological records were eligible, including 53 patients (65 hips). Fifteen hips (23.1%) were redislocated, OR with femoral osteotomy and pelvic osteotomy was the preferred surgical treatment 9 (13.8%). The initial acetabular index versus final acetabular index in total population was (38.9º ± 6.8º) and (31.9º ± 6.8º), respectively (t = 6.5, P < .001). The prevalence of AVN was 40%. Overall AVN in OR, femoral osteotomy and pelvic osteotomy were 73.3% versus CR 30%, P = .003. Unsatisfactory results ≤ 4 points on the Ömeroglu system were observed in hips that required OR with femoral and pelvic osteotomy. Hips with DDH treated with CR initially might had better radiological results than those treated with OR and femoral and pelvic osteotomies. Regular, good, and excellent results, ≥4 points on the Ömeroglu system, could be estimated in 57% of the cases, in whom CR was successful. AVN is frequently observed in hips with failed CR.

Postaxial hypoplasia of the lower extremity associated with congenital dislocation of the patella: A case report.

RATIONALE: Evaluation of clinical and radiologic abnormalities in patients with postaxial hypoplasia of the lower extremity (PHLE) for treatment decisions represents a major challenge, which is more complicated when PHLE is associated with congenital dislocation of the patella. PATIENT CONCERNS: : Herein, we present the case of an 8-year-old female patient with evident length inequality in her left lower extremity and inability to walk. DIAGNOSES: Radiological evaluation revealed PHLE with fibular hemimelia, proximal femoral focal deficiency, tarsal coalition, and congenital patellar dislocation of the patella. The right lower extremity was also affected by fibular hemimelia. INTERVENTIONS AND OUTCOMES: Surgical management included the Roux-Goldthwait technique for patellofemoral joint realignment, a medial knee stapled with Blount technique, and femur enlargement using the Wagner technique. The results from surgical intervention included a left femoral elongation of 6.7 cm featuring callus with angulation, displacement, and a discrepancy of 5 cm between femurs with a flexor contraction in the knee of -15° and a centralized knee. LESSON: PHLE accompanied by congenital dislocation of the patella has not been extensively described in the literature; therefore, there is no established management. Starting reconstruction at an early age, together with an adequate classification of the deformity, are essential factors when opting for limb reconstruction.

Survival at 30 days in elderly patients with hip fracture surgery who were exposed to hypothermia: Survival study.

ABSTRACT: The effect of hypothermia as a mortality risk factor at 30 days in the elderly who had hip fracture (HF) surgery is still controversial because it may be due to a set of poorly identified factors. In this study, we aim to determine if exposure to intra and immediate postoperative hypothermia increases the incidence of mortality at 30 days in elderly patients who had HF surgery.Survival study in the elderly who had HF surgery with and without exposure to hypothermia. Sociodemographic, anesthetic and surgical factors were collected. The temperature of the rectum was measured at the end of the surgery and in the recovery room. The effect of hypothermia was analyzed by the incidence of mortality at 30 days. Other results were considered, such as, surgical site infection (SSI), blood transfusions, and influence of implants used in the 30-day mortality.Three hundred eighty five subjects were eligible, to include 300. Inadvertent hypothermia was 12%, the 30-day overall mortality was 9% and in subjects with hypothermia it was 25% (P = .002). Subjects with hypothermia had a higher risk of SSI (relative risk 4.2, 95% confidence interval 1.3-13.6, P = .03) and receive more transfusions (relative risk 3.6, 95% confidence interval 2.0-6.5, P < .001).Elderly subjects with HF exposed to hypothermia who undergo hip hemiarthroplasty and who receive 2 or more blood transfusions during their treatment, are at greater risk of dying after 30 days of the surgery. Hypothermia, as a possible causative factor of mortality, should continue to be studied.

Superficial Thinning of the DIEP Flap: A Safe Option to Achieve an Aesthetic Reconstructed Breast in the Obese Patient.

BACKGROUND: Abdominal flap-based breast reconstruction is challenging in the overweight and obese population not only because of increased donor-site complications, but also because excessive flap thickness makes inset cumbersome, requiring thinning and remodeling that frequently result in aesthetically poor outcomes. METHODS: The authors started by studying 10 deep inferior epigastric artery perforator flaps with angiographic computed tomography. Then, they prospectively performed 21 breast reconstructions using a superficial thinning technique reliant on a constant suprafascial vessel as the pedicle for the remaining deep fat and compared the rate of complications with their previous experience using traditional flap thinning techniques. RESULTS: All samples studied showed a suprafascial division of the main perforator. Two constant branches were identified, one coursing over the Scarpa fascia and displaying a robust network of linking vessels with the subcutaneous and subdermal plexuses. That anatomical insight was used to develop a flap-thinning technique tested on 21 consecutive high-body mass index patients. A 7-year retrospective analysis (n = 164) showed no significant correlation between body mass index and incidence of complications except for a long-term upper pole step deformity that was associated with increasing body mass index (p = 0.001). No statistically significant difference in complications was found comparing high-body mass index patients from the retrospective group (n = 72) with the superficial thinning group, but a highly suggestive difference (p = 0.061) was found regarding the avoidance of the step deformity using the superficial thinning technique. CONCLUSION: The presence of a constant suprafascial perforator branch makes superficial DIEP thinning a safe technique that facilitates inset and improves the reconstructed breast contour of obese patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Medial Arm Flap: An Unexplored Option for Autologous Breast Reconstruction in the Setting of Morbid Obesity.

Currently, deep inferior epigastric perforator flap is undoubtedly the first choice for autologous breast reconstruction for most surgeons; however, there are instances where lower abdominal tissue is unavailable for microvascular transfer. In these cases, most surgeons choose gluteal or lower-extremity territories as donor sites.In the setting of morbid obesity, there is an increased risk of flap and donor site complications, as well as increased blood loss, surgical time, and risk of deep venous thrombosis, not to mention a more challenging surgical technique. Added to these problems, Tamoxifen intake and delayed or limited ambulation due to pain or surgical wounds increases deep venous thrombosis risk even further.The use of the upper arm as donor site for microvascular transfer avoids most of these problems and allows for immediate, comfortable ambulation. On the other hand, upper arm flaps have smaller caliber vessels for microanastomosis, shorter pedicles, and a limited amount of skin which makes them a viable option for only a select group of patients with redundant upper arm skin. We provide a previously undocumented proof-of-concept case report of a delayed breast reconstruction using the medial arm free flap that resulted in an uneventful postoperatory follow-up with a naturally textured and shaped reconstructed breast.

[Versatility of the microvascular fibular flap in limb reconstruction]. / Versatilidad del colgajo microvascular de peroné en reconstrucción de extremidades.

BACKGROUND: The structural characteristics of the fibula, strength, shape, length and limited donor site morbidity make it more suitable for reconstructing long bone defects larger than 6cm in the limbs. MATERIAL AND METHODS: A descriptive study was conducted using a non-probabilistic sample of consecutive cases undergoing on limb reconstruction with free fibular flap in the period from January 2010 to January 2015 in the Mexican Institute of Social Security No. 21, Monterrey Nuevo Leon. RESULTS: The mean age of the ten cases included was 25 years, with the most common diagnosis being trauma in 4 patients, osteosarcoma in 2, followed by one congenital pseudoarthrosis of the tibia, one non-union fracture, and one gunshot wounds, respectively. The most common location was tibia, followed by humerus, radius, ulna and femur. CONCLUSIONS: This study has shown that the fibular free flap can be an excellent option for management of long bone defects, regardless of cause of the injury. One or more skin islands can be added for coverage in exposure of deep tissue and osteosynthesis material, thus preserving the septocutaneous perforators.

[Face replantation using labial artery for revascularization. Case report]. / Reimplante facial con arteria labial para revascularización. Reporte de un caso.

BACKGROUND: Restoration of the face function and cosmetic appearance after a traumatic complex wound is a challenge for the plastic surgeon. Worldwide, few cases have been reported about face replantation. OBJECTIVE: To present the case of the first partial face replantation reported in the national bibliography, using the labial artery for revascularization. CLINICAL CASE: On June 19th 2011, a 7 years old male presented to the emergency room of the Mexican Institute of Social Security at Monterrey, Mexico, 4 hours after a partial face amputation secondary to a dog bite. The amputated segment was composed of 75% of the upper lip, 33% of the lower lip, oral commissure and 75% of the left cheek. The labial coronary artery and vein were anastomosed with 11-0 nylon sutures and the miorraphy of the orbicularis oris, the depressor anguli oris and the depressor labii inferioris with 4-0 vycril sutures. Six months after the surgery, the functional and aesthetic outcomes were excellent with reestablishment of total labial continence and total recovery of articulation of words. CONCLUSIONS: amputations of any facial component should be initially managed with replantation. The function and cosmetics are better than any other technique of reconstruction. The labial coronary artery is an excellent choice for revascularization up to 25% of the face (lips and cheek).

antecedentes: la restauración cosmética y funcional de la cara luego de un traumatismo complejo es todo un reto para el cirujano plástico. En el ámbito internacional se han reportado pocos casos de reimplante facial. Objetivo: reportar el caso del primer reimplante parcial de cara con la utilización de la arteria labial como aporte vascular. Caso clínico: paciente masculino de siete años de edad. Ingresó al servicio de Cirugía Plástica en el mes de junio de 2011 por lesiones secundarias en la cara ocasionadas por la mordedura de un perro. A la exploración física se encontró avulsión de 75% del labio superior, 33% del labio inferior, incluida la comisura oral, y 75% de la mejilla izquierda. Los músculos avulsionados incluían: el orbicular de los labios, depresor del ángulo oral y depresor del labio inferior. El tiempo total de isquemia fue de ocho horas. La anastomosis término-terminal de la arteria coronaria labial se efectuó con nylon 11-0, posteriormente se escogió la vena con mejor retorno y la anastomosis se realizó con nylon 11-0. Se hizo miorrafía de los músculos mencionados con vicril 4-0, la sutura de la mucosa oral se realizó con vicril 5-0, y de la piel con nylon 5-0. Seis meses después de la cirugía, el resultado cosmético y funcional se consideró excelente, con restablecimiento total de la continencia labial y articulación completa de las palabras. Conclusiones: las amputaciones de cualquier componente facial deben ser inicialmente tratadas con reimplante. La arteria coronaria labial es una buena opción para revascularización, incluso en 25% del total de la cara (labios y mejilla).

[Risk factors associated with trigger finger. Case-control study]. / Factores de riesgo asociados a tenosinovitisestenosante. Estudio de casos y controles.

OBJECTIVE: We undertook this study to identify risk factors in our population associated with trigger finger. The study was conducted at the Instituto Mexicano del Seguro Social, UMAE 21, Monterrey, Nuevo Leon, Mexico. METHODS: This was a case-control, retrospective, and observational study. There were 250 patients in each group. For cases, patients who were operated on for trigger finger from March 2006 to August 2006 were included. Controls included patients admitted to the Emergency Department with hand injuries that fulfilled the selection criteria. Risk factors analyzed were diabetes, hypertension, smoking, sex, age, weight, and 19 different occupations. RESULTS: Mean age of the cases was 52 years (SE +/- 14.19 years) with a median and mode of 53 years. The right hand was the most common with the middle, thumb, ring, index and little fingers, respectively. A significant statistical relationship was found: females (OR 7.57, 95% CI 5.07-11.31); diabetes (OR 3.72, 95% CI 2.43-5.70); obesity (OR 1.49, 95% CI 1.02-2.19). With regard to occupation, a statistical relationship was found: homemaker (OR 2.44, 95% CI 1.62-3.69); seamstress (OR 4.8, 95% CI 1.3-21.6); and secretary (OR 2.74, 95% CI 1.38-5.52). CONCLUSIONS: Trigger finger is a common pathology in our population and is more frequent in women >53 years old. It may be related to diabetes, body mass index (obesity) and certain occupations such as secretary, seamstress and homemaker.

[Adenocarcinoma of the gallbladder as a histopathological finding after cholecystectomy]. / Adenocarcinoma de vesícula biliar como hallazgo histopatológico posterior a colecistecomía.

OBJECTIVE: We wanted to determine the incidence in our population of gallbladder adenocarcinoma based on a histopathologic study done after cholecystectomy in patients with a diagnosis of gallstones. MATERIAL AND METHODS: We made a census-type study during the last 3 years that included a total of 4548 gallbladders. Histopathologic results were analyzed and recollected in an established format. Finally, we calculated the incidence of malignant neoplasias of gallbladder in our hospital. RESULTS: The most common histopathologic finding was cholesterolosis (incidence: 26%), followed by xanthogranulomatous gallbladder (incidence: 0.94%). The incidence of gallbladder cancer was 0.54% (25 cases), the most common type being adenocarcinoma (incidence: 0.48%). CONCLUSIONS: The incidence of gallbladder cancer in our hospital is among the lowest limits compared with the literature worldwide.
