Introdução: o músculo reto femoral é o músculo mais frequentemente lesado do grupo quadríceps durante chutes e corridas repetitivas, apesar de suas avulsões serem raras. A dor localizada na coxa proximal e a incapacidade de flexionar o quadril e/ou estender o joelho associado à história do paciente de contração violenta ou alongamento forçado do grupo muscular do quadríceps femoral podem indicar uma avulsão do reto femoral. Objetivo: relatar um caso e revisar a literatura acerca desta lesão incomum. Materiais e Métodos: revisão do prontuário, registro fotográfico do método diagnóstico e revisão da literatura. Resultados: homem de 46 anos com dor localizada no quadril esquerdo com irradiação para a coxa por três meses após cair no chão com a região dolorida em um jogo de futebol. A dor começou subitamente uma semana após a queda. A ressonância magnética do quadril apresentava avulsão completa do reto femoral esquerdo, distando 2 cm da espinha ilíaca anterior inferior com efusão líquida adjacente. Conclusão: este relato demonstra a dificuldade de diagnosticar essa lesão, pois o seu exame físico é inespecífico, podendo simular patologias mais complexas, necessitando de exames complementares para seu correto diagnóstico.

Introduction: the rectus femoris muscle is the most frequently injured muscle of the quadriceps group during repetitive kicking and sprinting. Avulsions of the rectus femoris are rare injuries. Pain located at the proximal thigh and disability in flexing the hip and/or extending the knee associated with a patient history of a violent contraction or forceful stretching of the quadriceps femoris muscle group can indicate an avulsion of rectus femoris. Objective: report a case and review the literature about this uncommon lesion. Materials and Methods: we reviewed medical records, photographic records of diagnostic methods, and reviews from the literature. Results: a 46-year-old man with pain located at the left anterior hip with irradiation to the thigh for three months after falling to the ground with the sore region in a soccer game. The pain started suddenly one week after the fall. The MRI of the hip featured complete avulsion of the left rectus femoris, being 2 cm distal from the anterior inferior iliac spine with adjacent liquid effusion. Conclusion: this report demonstrates the difficulty of diagnosing this lesion, since its physical examination is non-specific, and it can simulate more complex pathologies, requiring complementary tests for its correct diagnosis.

El tumor de células gigantes de hueso es un tumor raro de características benignas con un comportamiento agresivo localmente. Predomina en mujeres y por lo general se presenta en la epífisis y metáfisis de los huesos largos. El propósito de este estudio es presentar el caso de un paciente con una lesión tumoral de rodilla y muslo izquierdos de 2 años de evolución y señalar las características diagnósticas de este tumor al mismo tiempo que se revisan los métodos imagenológicos recientes para su confirmación. Se presenta a un paciente masculino de 19 años de edad, que comenzó con dolor, aumento de volumen de la rodilla y muslo izquierdos, acompañado de impotencia funcional. Se reportaron los hallazgos clínicos, radiográficos e histológicos. Debido a la demora entre el inicio de los síntomas y el diagnóstico se practicó el tratamiento quirúrgico del miembro afectado (amputación). Tras 10 meses de observación no se han presentado recidivas o metástasis. Se envió al Servicio de Oncología para valorar e tratamiento con radioterapia. El tumor de células gigantes del hueso es un tumor raro, de buen pronóstico, pero que puede recidivar y causar metástasis cuando se maligniza. Por la posibilidad de transformación en sarcoma requiere estudio y observación periódica. El tiempo para realizar el diagnóstico es fundamental y debe pensarse en este tumor en caso de lesiones líticas de hueso reportadas por imagenología(AU)

The giant cell tumor of bone is a rare benign tumor with a locally aggressive behavior. It predominates in women and usually occurs in the epiphysis and metaphysis of long bones. To present a patient with a tumor lesion left knee and thigh two years of evolution, also noted the diagnostic characteristics of this tumor while recent imaging methods are reviewed for confirmation. 19-year-old male who began with pain, increased volume of the knee and left thigh, accompanied by functional impotensia. clinical, radiological and histological findings were reported. Because of the delay between the onset of symptoms and diagnosis surgical treatment of the affected limb (amputation) was performed. After ten months of observation there have been no recurrences or metastases. The giant cell tumor of bone is a rare tumor with good prognosis but can recur and metastasize when it becomes malignant. The possibility of transformation in sarcoma requires periodic study and observation. The time for diagnosis is essential and should think of this tumor in case of lytic bone lesions reported by imaging(AU)

Abstract Reactivation of chronic Trypanosoma cruzi infection in solid organ transplant recipients (SOTRs) has been reported. The patient presented with a 2-week history of two painful erythematous, infiltrated plaques with central ulceration and necrotic crust on the left thigh. She had a history of chronic indeterminate Chagas disease (CD) and had received a kidney transplant before 2 months. Skin biopsies revealed lobular panniculitis with intracellular amastigote forms of T. cruzi. The patient was diagnosed with CD reactivation. Treatment with benznidazole significantly improved her condition. CD reactivation should be suspected in SOTRs living in endemic areas with clinical polymorphism of skin lesions.

BACKGROUND@#Fetal weight is an important parameter to ensure maternal and child safety. The purpose of this study was to use three-dimensional (3D) limb volume ultrasound combined with fetal abdominal circumference (AC) measurement to establish a model to predict fetal weight and evaluate its efficiency.@*METHODS@#A total of 211 participants with single pregnancy (28-42 weeks) were selected between September 2017 and December 2018 in the Beijing Obstetrics and Gynecology Hospital of Capital Medical University. The upper arm (AVol)/thigh volume (TVol) of fetuses was measured by the 3D limb volume technique. Fetal AC was measured by two-dimensional ultrasound. Nine cases were excluded due to incomplete information or the interval between examination and delivery >7 days. The enrolled 202 participants were divided into a model group (134 cases, 70%) and a verification group (68 cases, 30%) by mechanical sampling method. The linear relationship between limb volume and fetal weight was evaluated using Pearson Chi-squared test. The prediction model formula was established by multivariate regression with data from the model group. Accuracy of the model formula was evaluated with verification group data and compared with traditional formulas (Hadlock, Lee2009, and INTERGROWTH-21st) by paired t-test and residual analysis. Receiver operating characteristic curves were generated to predict macrosomia.@*RESULTS@#AC, AVol, and TVol were linearly related to fetal weight. Pearson correlation coefficient was 0.866, 0.862, and 0.910, respectively. The prediction model based on AVol/TVol and AC was established as follows: Y = -481.965 + 12.194TVol + 15.358AVol + 67.998AC, R2adj = 0.868. The scatter plot showed that when birth weight fluctuated by 5% (i.e., 95% to 105%), the difference between the predicted fetal weight by the model and the actual weight was small. A paired t-test showed that there was no significant difference between the predicted fetal weight and the actual birth weight (t = -1.015, P = 0.314). Moreover, the residual analysis showed that the model formula's prediction efficiency was better than the traditional formulas with a mean residual of 35,360.170. The combined model of AVol/TVol and AC was superior to the Lee2009 and INTERGROWTH-21st formulas in the diagnosis of macrosomia. Its predictive sensitivity and specificity were 87.5% and 91.7%, respectively.@*CONCLUSION@#Fetal weight prediction model established by semi-automatic 3D limb volume combined with AC is of high accuracy, sensitivity, and specificity. The prediction model formula shows higher predictive efficiency, especially for the diagnosis of macrosomia.@*TRIAL, NCT03002246;

RESUMO O objetivo deste estudo foi verificar se a formação do arco longitudinal do pé interfere na distribuição da pressão plantar e na flexibilidade dos músculos posteriores da coxa. O método de estudo foi transversal e as impressões plantares foram obtidas usando o plantígrafo e analisadas segundo o método Viladot. A distribuição plantar e a flexibilidade foram avaliadas pela baropodometria e pelo banco de Wells, respectivamente. Foi observado que crianças com pés cavos apresentam maior flexibilidade quando comparadas às que têm o pé normal (p=0,02); e também que pés cavos apresentam maior pressão, ou seja, maior sobrecarga em calcâneo quando comparados àqueles com o arco plantar normal (p=0,02 membro inferior direito e p=0,03 membro inferior esquerdo). A avaliação do arco longitudinal medial mostra que crianças com pés cavos apresentam maior flexibilidade dos músculos posteriores de membro inferior. Os pés cavos também estão associados com maior descarga de peso em região de calcâneo.

RESUMEN El objetivo de este estudio fue verificar si la formación del arco longitudinal del pie interfiere con la distribución de la presión plantar y la flexibilidad de los músculos posteriores del muslo. El método de estudio fue transversal y las huellas plantar se obtuvieron utilizando el plantigraph y se analizaron según el método de Viladot. La distribución plantar y la flexibilidad se evaluaron mediante baropodometría y el banco de Wells, respectivamente. Se observó que los niños con pies huecos tienen mayor flexibilidad en comparación con aquellos con pies normales (p=0,02); y también que los pies huecos tienen una mayor presión, es decir, una mayor sobrecarga del talón en comparación con aquellos con arco plantar normal (p=0,02 miembro inferior derecho y p=0,03 miembro inferior izquierdo). La evaluación del arco longitudinal medial muestra que los niños con pies huecos tienen una mayor flexibilidad en los músculos posteriores de la extremidad inferior. Los pies huecos también están asociados con una mayor descarga de peso en la región del talón.

ABSTRACT Objective: To evaluate whether the formation of the longitudinal arch of the foot interferes with the distribution of plantar pressure and the pliability of the posterior thigh muscles. Methodology: a cross-sectional study and the footprints were obtained using the footprinting mat and analyzed according to the Viladot method. Plantar distribution and pliability were assessed by baropodometry and Wells' bank, respectively. Results: It was observed that children with cavus feet present greater pliability when compared to those with normal feet (p=0.02). Also, the cavus feet exhibit higher pressure, that is, a greater heel overload compared to those with normal plantar arch (p=0.02 lower right limb and p=0.03 lower left limb). Conclusions: The evaluation of the medial longitudinal arch shows that children with cavus feet have greater pliability of the lower limb posterior muscles. The cavus feet are also associated with higher pressure in the calcaneal region.

Objective@#The objective of this report was to demonstrate the clinical application of free flow-through anterolateral thigh flaps for the treatment of high-tension electrical wrist burns.@*Methods@#We collected the data of 8 patients with high-tension electrical wrist burns admitted to Beijing Jishuitan Hospital from January 2014 to December 2018. The clinical and pathological data were extracted from electronic hospital medical records. We obtained follow-up information through clinic visits.@*Results@#The injury sites for all 8 patients were the wrists, specifically 5 right and 3 left wrists, all of which were on the flexor side. Five patients had ulnar artery embolism necrosis and patency, with injury to the radial artery. Two patients had ulnar and radial arterial embolization and necrosis. The last patient had ulnar arterial embolization and necrosis with a normal radial artery. After debridement, the wound area ranged from 12 cm × 9 cm to 25 cm × 16 cm. The diagnoses for the eight patients were type II to type III high-tension electrical wrist burns. Free flow-through anterolateral thigh flaps (combined with great saphenous vein transplantation if necessary) were used to repair the wounds. The prognosis for all patients was good after six months to one year of follow-up.@*Conclusion@#Treating wrist types II and III high-tension electrical burns is still challenging in clinical practice. The use of free flow-through anterolateral thigh flaps (combined with great saphenous vein transplantation if necessary) to repair the wound and to restore the blood supply for the hand at the same time is a good choice for treating severe wrist electrical burns.

OBJECTIVE@#To explore the clinical efficacy of silver needle lumbar and sacral spine approach in treating gluteal muscle syndrome.@*METHODS@#Eighty-seven patients with gluteal muscle syndrome treated with silver needles in the Department of Rehabilitation Medicine of our hospital from September 2017 to September 2019 were selected. Except for symptoms of waist and hip pain and discomfort, all selected patients were examined by CT or MRI to confirm pathological imaging changes such as inflammatory exudation of the gluteal muscle. The 87 patients with gluteal muscle syndrome were divided into 2 groups according to the digital table method, and 42 patients in the lumbosacral approach group, including 19 males and 23 females, aged (50.70±12.45) years old, and disease duration of (1.63±1.27) years;45 cases in the buttock approach group, including 20 males and 25 females, aged (52.80±12.18) years old, with a course of disease of (1.78±1.22) years. The lumbosacral approach group was treated with spinal L to S bilateral articular process joints and L transverse process acupuncture needles, and the buttock approach group was treated with the gluteus medulla wing starting point and femoral trochanter stop. The VAS scores, soft tissue tenderness thresholds, and hip abductor muscle strength of the affected group were measured before and 4 weeks after treatment in the two groups. The clinical efficacy was also evaluated 4 weeks after treatment.@*RESULTS@#After 4 weeks, the VAS score of the lumbosacral approach group was 1.26±0.70, and the buttock approach group was 1.18±0.74, which were significantly lower than those before treatment, but there was no statistical difference between the groups (>0.05). The soft tissue tenderness threshold and ipsilateral hip abductor muscle strength were (5.51±0.70) kg and (10.34±2.19) kg in the lumbosacral approach group, and (4.78±1.05) kg, (9.33±1.42) kg in the buttock approach group. The results in the lumbosacral approach group was better than those in the buttock approach group(<0.05). The clinical efficacy of the lumbosacral approach group:16 cases got an excellent result, 20 good, 5 fair and 1 poor;in the buttock approach group, 13 excellent, 17 good, 12 fair and 3 poor. The clinical efficacy between the two groups had statistical difference (<0.05).@*CONCLUSION@#In the treatment of gluteus medius syndrome with silver needle, lumbosacral approach and buttock approach can effectively relieve the pain. Compared with the improvement of soft tissue tenderness threshold and hip abductor muscle strength, the upper lumbosacral approach is more prominent, and the overall clinical effect is more significant.

Resumen: Objetivo: Analizar el nivel de citoquinas proinflamatorias en la grasa articular del paquete adiposo en pacientes con gonartrosis, en relación con la grasa subcutánea del muslo. Material y métodos: Efectuamos un estudio de grasa del paquete adiposo articular de la rodilla afectada de artrosis y de la grasa subcutánea del muslo del mismo lado, a la mayor distancia de la articulación en seis pacientes con gonartrosis grave, con una edad media de 68 años (rango: 55-81 años). De las muestras de grasa se obtuvieron las células mesenquimales progenitoras. Los sobrenadantes de células mesenquimales obtenidas se utilizaron para analizar factores inflamatorios (IL-1b, IL6, IL8, IL9, IL1ra, IL12, IL13, IL15) y angiogénicos (VEGF, PDGF bb), así como citoquinas inmunomoduladoras (IP-10 e INF-γ) y se compararon las medias de dos muestras. Resultados: El análisis cuantitativo reveló una disminución significativa (p < 0.05) de IL-1b, IL6, IL8, IL9, IL1ra, IL12, IL13 y un aumento de IL15 en la grasa de Hoffa frente al tejido adiposo subcutáneo. Del mismo modo, el análisis de factores angiógenicos como VEGF y PDGF bb, al igual que los factores IP-10 e INF-γ presentaron una disminución significativa en la grasa de Hoffa (p < 0.05) frente al tejido adiposo subcutáneo. Discusión: Las células mesenquimales del paquete adiposo articular de la rodilla artrósica grave muestran una disminución significativa de citoquinas inflamatorias, aun en el estado crónico, y una disminución significativa de factores angiogénicos y citoquinas inmunomoduladoras (IP10 e INF).

Abstract: Objective: To analyze the level of pro-inflammatory cytokines in osteoarthritis knee joint fat pad in relation to the subcutaneous fat of the thigh. Material and methods: We performed a study of fat of the knee joint adipose affected of osteoarthritis and subcutaneous fat of the thigh of the same side to the greater distance of the joint in six patients with severe gonarthrosis, with a mean age of 68 years (range: 55-81 years). From the fat samples the progenitor mesenchymal cells were obtained. The supernatants of mesenchymal cells obtained to analyze inflammatory factors (IL-1b, IL6, IL9, IL1ra, IL12, IL13, IL15) and angiogenic (VEGF, PDGF bb) and immunomodulatory cytokines (IP-10 and INF-γ) means of two samples. Results: Quantitative analysis revealed a significant (p < 0.05) decrease in IL-1b, IL6, IL8, IL9, IL1ra, IL12, IL13 and increase of IL15 in Hoffa fat pad versus subcutaneous adipose tissue. Likewise, the analysis of angiogenic factors such as VEGF and PDGF, as well as factors IP-10 and INF-γ presented a significant decrease (p < 0.05) in Hoffa fat pad versus subcutaneous adipose tissue. Discussion: Mesenchymal cells from the adipose tissue of the severe osteoarthritic knee show a significant decrease in inflammatory cytokines even in the chronic state and a significant decrease in angiogenic factors and immunomodulatory cytokines (IP10 and INF).

Abstract: The authors report the case of a 62-year-old man with a history of total left hip arthroplasty nine years previously presenting with a large infiltrated plaque on the posterior area of the left thigh with three months of evolution without systemic symptoms or elevated inflammatory markers. Computed tomography of the left lower limb revealed a 12-centimeter linear extension of the lesion to the posterior part of the left proximal femur. Prosthesis joint infection, although rare, is a surgical complication to be taken into account, even if the surgery was performed many years before.

Abstract Objectives To correlate the mean time of return of athletes to sport after acute injury of the thigh muscle with hematoma that was punctured or not. Methods Study based on clinical intervention, controlled and non-randomized with 20 amateur and professional athletes, divided into moderate and total or subtotal thighs lesions, according with the Munich Consensus Statement. Nine athletes were included in the intervention group and 11 athletes in the control group. In the intervention group, the athletes were submitted to a puncture of the hematoma, associated to physical therapy; the control group did only physical therapy. The variable mean time of return to sport was analyzed using the Mann-Whitney test and a significance level of 5% (p < 0.05; 95% confidence interval [CI]) was established. Results The mean group was composed mostly of men, eight of them were amateur athletes. There were three women, two of whom were amateur athletes. The average age of participants was 34.70 ± 12.79 years. There were 13 patients with posterior thigh lesions, 5 with anterior lesions and two with adductor lesions. Considering all injuries, the mean time of return to sport was of 48.50 ± 27.50 days in the intervention group. In the control group, this period was of 102.09 ± 52.02 days, showing a statistically significant difference between them (p = 0.022). Conclusion In the present study, hematoma drainage in athletes with moderate and total or subtotal muscle injuries associated with hematomas decreased their return time to sport.

Aneurismas verdadeiros isolados da artéria femoral superficial (AFS) são raros, representando 0,5% dos aneurismas periféricos. Até 2012, existiam relatos na literatura de apenas 103 pacientes com aneurismas verdadeiros isolados da AFS. As principais complicações associadas são: trombose, embolização distal e rotura, sendo a última a mais comum. Os autores relatam o caso de um paciente masculino, de 55 anos, atendido emergencialmente com dor e massa pulsátil em coxa esquerda, condição posteriormente diagnosticada como ruptura de aneurisma da AFS. O paciente foi submetido à correção cirúrgica emergencial com ligadura do aneurisma e revascularização com veia safena magna reversa, com evolução satisfatória

Isolated true aneurysms of the superficial femoral artery (SFA) are rare, accounting for 0.5% of peripheral aneurysms. The literature up to 2012 contains reports of just 103 patients with isolated SFA aneurysms. The main complications are thrombosis, distal embolization, and rupture, which is the most common of the three. The authors report the case of a 55-year-old male patient admitted to the emergency service with pain and a pulsatile mass in the left thigh, subsequently confirmed as rupture of an SFA aneurysm. The patient underwent open aneurysm repair with ligature and revascularization with a reversed saphenous vein bypass

A Morel-Lavallée lesion is a posttraumatic, closed internal degloving injury caused by shearing force abruptly separating the skin and superficial fascia from the deep fascia and creating a potential space. Blood, lymphatic fluid, and debris collect and fill the space. The most commonly affected sites are the thigh, knee, hip, and pelvic area, but the lesion can occur anywhere in the body. Among various treatments, surgical procedure is a good option if the lesion is chronic and a thick peripheral capsule has developed. We report an uncommon case of a chronic Morel-Lavallée lesion in the sacrococcygeal area, a rarely reported location, with an associated coccygeal fracture and dislocation.

Hepatocellular carcinoma is one of the most common cancers worldwide. Extrahepatic metastasis commonly occur in the lung, lymph, nodes, bone, and adrenal glands. On the other hand, a metastasis of hepatocellular carcinoma to the skeletal muscle is rare. A 42-year-old woman presented for evaluation of a palpable mass with tenderness in her right thigh area. She has been diagnosed with hepatocellular carcinoma and pulmonary metastasis seven years ago and has received treatment. We performed incisional biopsy with suspicion of hepatocellular carcinoma metastasis from imaging studies and blood test results. The patient was finally diagnosed with metastasis of hepatocellular carcinoma in the semimembranosus muscle and treated by extensive resection. We report this case with a review of the relevant literature.

BACKGROUND: Adequate bone formation around titanium alloy implants is integral to successful implantation surgery. Stem cell-coated implants may accelerate peri-implant bone formation. This study investigates the effect of platelet-rich plasma (PRP) pretreatment on a titanium-alloy surface in terms of proliferation and osteogenic differentiation of human adipose-derived stem cells (hADSCs). METHODS: Allogenic leukocyte-depleted PRP was obtained from blood supernatants. The hADSCs were isolated from thigh subcutaneous fat tissue. Grit-blasted titanium plugs were used in two different groups. In one group, 200 µL of PRP was added to the grit-blasted titanium plugs. The hADSCs were seeded in two groups: grit-blasted titanium plugs with or without PRP. The number of hADSCs was measured after 4 hours, 3 days, and 7 days of culture using Cell Counting Kit-8. Osteogenesis of hADSCs was measured by using an alkaline phosphatase activity assay on days 7 and 14, and a calcium assay on days 14 and 21. Osteogenic gene expression was measured by using reverse transcription polymerase chain reaction analysis of alkaline phosphatase, osteocalcin, and type I collagen mRNA. The microscopic morphology of grit-blasted titanium plugs with or without PRP was examined with a field-emission scanning electron microscope using a JSM-7401F apparatus on days 1 and 7. RESULTS: Proliferation and osteogenic differentiation of hADSCs were found to be significantly higher on the grit-blasted titanium alloy preprocessed with PRP than the same alloy without pretreatment. Furthermore, a structural fibrillar mesh developed compactly on the grit-blasted titanium alloy with the PRP pretreatment. CONCLUSIONS: Our results demonstrate that a hADSC-based approach can be used for tissue-engineered peri-implant bone formation and that PRP pretreatment on the grit-blasted titanium alloy can improve proliferation and osteogenic differentiation of hADSCs.

PURPOSE: The most common risk factor for fecal incontinence (FI) is obstetric injury. FI affects 1.4%–18% of adults. Most patients are unaware when they are young, when symptoms appear suddenly and worsen with aging. Autologous fat graft is widely used in cosmetic surgical field and may substitute for injectable bulky agents in treating FI. Authors have done fat graft for past several years. This article reports the effectiveness of the fat graft in treating FI and discusses satisfaction with the procedure. METHODS: Fat was harvested from both lateral thighs using 10-mL Luer-loc syringe. Pure fat was extracted from harvests and mixed with fat, oil, and tumescent through refinement. Fats were injected into upper border of posterior ano-rectal ring, submucosa of anal canal and intersphincteric space. Thirty-five patients with FI were treated with this method from July 2016 to February 2017 in Busan Hangun Hospital. They were 13 male (mean age, 60.8 years) and 22 female patients (mean age, 63.3 years). The Wexner score was checked before procedure. We evaluated outcome in outpatients by asking the patients. For 19 patients we checked the Wexner score after procedure. RESULTS: Symptom improved in 29 (82.9%), and not improved in 6 (17.1%). In 2 of 6 patients, they felt better than before procedure, although not satisfied. No improvement in 4. Mean Wexner score was 9.7 before procedure. There were no serious complications such as inflammation or fat embolism. CONCLUSION: Autologous fat graft can be an effective alternative treatment for FI. It is safe and easy to perform, and cost effective.

PURPOSE: A retrospective analysis of mid- to long-term clinical and radiological outcomes of Korean patients over 60 years of age who underwent hip arthroplasty using a cementless rectangular tapered stem according to Dorr proximal femur geography. MATERIALS AND METHODS: From January 2007 to December 2013, 107 patients (112 hips) underwent hip arthroplasty using the C2 stem. The mean age of patients was 77.4 years (range, 60–91 years) and the mean follow-up duration was 91.1 months (range, 60–116 months). All patients were evaluated clinically and radiologically with special attention to Dorr femoral bone classification, implant fixation, radiolucent line (RLL), and thigh pain. RESULTS: All implants demonstrated radiographic evidence of stable fixation by bone ingrowth without any change in position. The mean Harris hip score improved from 65.5±16.0 (preoperative) to 90.5±15.9 (final follow-up) (P<0.001). Incidence of RLLs, stress shielding, and thigh pain was highest in patients with Dorr type A (RLL, P=0.021; stress shielding, P=0.030; thigh pain, P<0.001). One stem revision was performed due to deep infection. The Kaplan–Meier survival rate of the femoral stem was 97.6%. CONCLUSION: The overall survival rate of the C2 stems was greater than 97%; there were no significant differences in survival of the C2 stem according to the Dorr classification. The incidences of RLL of thigh pain and RLL were significantly different among Dorr classifications and (highest in patients with Dorr type A).

Profound weight loss with painful symmetrical peripheral neuropathy in diabetic patients was first described as diabetic neuropathic cachexia more than 4 decades ago. It is a distinct type of diabetic peripheral neuropathy that occurs in the absence of other microvascular and autonomic complications of diabetes. The mechanism and precipitating cause are unknown. It was reported to have good prognosis with spontaneous recovery within months to 2 years. However, it was frequently missed by clinicians because the profound weight loss is the most outstanding complaint, rather than the pain, numbness, or weakness. This often leads to extensive investigation to exclude more sinister causes of weight loss, particularly malignancy. We report a case of a young woman with well-controlled diabetes who presented with profound unintentional weight loss (26 kg), symmetrical debilitating thigh pain, and clinical signs of peripheral neuropathy. As the disease entity may mimic an inflammatory demyelinating cause of neuropathy, she was treated with a trial of intravenous immunoglobulin, which failed to give any significant benefit. However, she recovered after 6 months without any specific treatment, other than an antidepressant for the neuropathic pain and ongoing rehabilitation.
