Donor Site Morbidity of Nonvascularized Bone Graft: A Systematic Review

ABSTRACT Objective: To evaluate the donor site morbidity of iliac and fibular nonvascularized bone graft after mandibular resection. Material and Methods: This study was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in PubMed, Proquest, Science Direct, and Ebsco. A total of 12 studies met the criteria of studies in humans using iliac and fibular nonvascularized bone grafts in mandibular reconstruction after mandibular resection. Results: A greater proportion of patients received iliac nonvascularized bone graft (88.9%) than fibular nonvascularized bone graft (11.1%). Of the 385 cases of iliac bone graft, 153 cases (40%) experienced complications at the iliac donor site, whereas in 48 cases of fibular bone graft, two (4%) experienced complications at the donor site. Hemorrhage, bone fracture, infection requiring debridement, and hematoma were the major complications. Conclusion: The morbidity rate of the nonvascularized bone graft donor site of the fibula (4%) tended to be lower than that of the ilium (40%). Patient age and defect size were not significantly correlated with the occurrence of morbidity donor sites in either the ilium or fibula.

Objective:To evaluate the efficacy of esketamine combined with fascia iliaca compartment-subarachnoid block in optimizing anesthesia in elderly patients undergoing hip fracture surgery.Methods:Sixty-two American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ elderly patients of either sex, aged 60-85 yr, with body mass index of 18.5-30.0 kg/m 2, were divided into 2 groups ( n=31 each) using a random number table method: fascia iliaca compartment-subarachnoid block group (FS group) and esketamine combined with fascia iliaca compartment-subarachnoid block group (ES group). In FS group, patients underwent ultrasound-guided fascia iliaca compartment block at 30 min before the operation of subarachnoid anesthesia on the surgical side. In ES group, esketamine 0.25 mg/kg was intravenously administered at 5 min before skin incision based on the fascia iliaca compartment-subarachnoid block. Patient-controlled intravenous analgesia was used for postoperative analgesia, and tramadol 1 mg/kg was intravenously given for rescue analgesia when numerical rating scale score > 4. The pressing times of patient-controlled analgesic pump, the number of rescue analgesia and consumption of tramadol were recorded within 48 h after operation. The occurrence of postoperative adverse reactions (respiratory depression, nausea and vomiting, dizziness, drowsiness, pruritus, illusion, nightmares) was recorded. Results:Compared with FS group, the consumption of postoperative tramadol was significantly decreased, and the pressing times of patient-controlled analgesic pump and the number of rescue analgesia were reduced in ES group ( P<0.05). There were no significant differences in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:Combination of esketamine with fascia iliaca compartment-subarachnoid block for hip fracture surgery can raise postoperative analgesia and optimize clinical management strategies in elderly patients.

Periosteum-covered iliac crest autografts for treatment of severe osteochondral lesions of talus / 中华创伤杂志

Objective:To explore the clinical efficacy of periosteum-covered iliac crest autografts for treatment of severe osteochondral lesions of talus （OCLTs）.Methods:A retrospective case series study was used to analyze the clinical data of 26 patients with severe OCLTs treated at Zhejiang Armed Police Corps Hospital from January 2013 to October 2019. There were 21 males and 5 females，aged 17-49 years ［（36.3 ± 10.9）years］. All patients were treated using periosteum-covered iliac crest autografts. The visual analogue scale （VAS），American Orthopedic Foot and Ankle Society （AOFAS） ankle-hindfoot score and ankle joint range of motion （ROM） were assessed before operation，6 months after operation and at the last follow-up （≥ 12 months）. The area of talus injury with MRI at the same level was recorded before operation and at the last follow-up. The healing of talus and joint surface was detected with CT at the last follow-up. The healing of the incision and osteotomy site and complications were observed.Results:All patients were followed for 12 to 22 months［（15.1 ± 3.2）months］. The VAS was （2.4 ± 0.9）points and （1.7 ± 0.6）points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （5.4 ± 1.2）points （ P < 0.01）. Meanwhile，the VAS at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The AOFAS ankle-hindfoot score was （71.7 ± 7.8）points and （87.8 ± 6.2） points at postoperative 6 months and at the last follow-up，significantly lower than the preoperative （66.5 ± 7.5） points （ P < 0.01）. Meanwhile，the AOFAS ankle-hindfoot at the last follow-up was significantly lower than that at postoperative 6 months （ P < 0.01）. The ankle ROM was （58.4 ± 5.5）° and （70.0 ± 4.9）° at postoperative 6 months and at the last follow-up，significantly improved when compared to the preoperative （42.3 ± 8.1）° （ P < 0.01）. Meanwhile，the ankle ROM at the last follow-up was significantly improved when compared to that at postoperative 6 months （ P < 0.01）. The area of talus injury with MRI at the same level was 0.67（0.55，0.89）cm 2 at the last follow-up，significantly improved when compared to preoperative 2.64（1.98，3.68）cm 2 （ P < 0.01）. The transplantation had neither obvious defects nor joint surface steps based on CT findings. All surgical incisions were healed by first intention. There were no complications such as incision infection，skin necrosis，nonunion of osteotomy，malunion or severe ankle joint disorder except that 8 patients had residual local subchondral bone?marrow?edema-like?signal?and 2 patients showed delayed healing of medial malleolus osteotomy. Conclusion:For patients with severe OCLTs，periosteum-covered iliac crest autografts can effectively relieve ankle pain，improve ankle function，and reduce the area of injury.

Effect of digital and 3D printing technology combined with non-vascularized ilium in repairing post-traumatic bone defect in maxillary anterior teeth area / 中华创伤杂志

Objective:To explore the effect of digital technology and 3D printing technology combined with non-vascularized ilium bone in repairing post-traumatic bone defect in maxillary anterior area.Methods:A retrospective case series study was performed to analyze clinical data of 8 patients with severe bone defect in maxillary anterior area after trauma admitted to First Affiliated Hospital of Zhengzhou University from June 2013 to January 2018. There were 6 males and 2 females, with the age of 18-43 years [(31.9±9.0)years]. The maxillary bone was reconstructed before surgery by employing digital technology. The intercept range of ilium was determined according to the best form of defect to be recovered. Then the model and guide plate was printed out by employing 3D print technology. The titanium mesh was prebended on the model. The bone was extracted and Onlay bone grafting was performed according to the guide plate. The implant restoration was performed 6 to 9 months after operation, and porcelain crown restoration was performed 4 to 6 months later. The iliac bone survival and postoperative complications were detected 6 months after bone grafting. The near-middle-far and vertical bone elevation of the alveolar ridge as well as bone elevation of lip palatal were measured before implantation. The condition around the implants was observed 6 months after porcelain crown restoration. The visual analogue score (VAS) was used to evaluate the pain after iliac bone transplantation and implantation. The implant stability coefficient (ISQ) was applied to assess the stability of the implants on the day and 4 months after operation.Results:All the patients were followed up for 24-48 months [(33.3±9.7)months]. Eight patients with non-vascularized iliums were all survived. There was one patient with mild infection after bone grafting and one patient with gingival inflammatory hyperplasia after implantation, both of whom were healed after treatment. There was no obvious peri-implant inflammation or absorption of the grafted bone. The increase in height of the alveolar on the mesial and distal bone, vertical bone and labial-palatal bone was 30.28-39.67 mm, 9.58-11.32 mm and 2.06-7.41 mm, respectively. All the implants showed good osseointegration. The VAS after implantation was (3.4±0.7)points, significantly alleviated compared with the preoperational level [(7.3±2.0)points] ( P<0.05). The ISQ was 84.4±1.9 at postoperative 4 months, showing no significant difference from that on the day after operation (72.9±1.4) ( P>0.05). Conclusions:In repair of severe bone defect in maxillary anterior area after trauma, the digital and 3D printing technology combined with non-vascularized ilium can improve the survival rate of bone grafts. The implant restoration after operation can reduce pain, restore the patients' facial appearance and achieve satisfactory oral physiological function.

Síndrome de Valentino: una causa no común de abdomen agudo. Reporte de un caso / Valentino Syndrome: an uncommon cause of acute abdomen. Case Report.

INTRODUCCIÓN: El síndrome de Valentino es la perforación de una úlcera péptica a nivel gástrico o duodenal, en donde el paciente se presenta de forma atípica, con un cuadro clínico sugerente de apendicitis aguda, asociado a peritonitis localizada. Al ser una entidad con escasos reportes a nivel mundial y con ningún caso documentado en el Ecuador, es fundamental difundir el presente caso clínico para conocimiento de la comunidad médico-científica. CASO CLÍNICO: Paciente masculino de 63 años, acudió a servicio de emergencia con dolor abdominal de 12 horas de evolución localizado en fosa iliaca derecha asociado a signos de irritación peritoneal y descompensación hemodinámica, sugestivo de peritonitis. Se realizó laparotomía exploratoria. EVOLUCIÓN: En el procedimiento quirúrgico no se evidenciaron cambios inflamatorios en el apéndice y tras la exploración de la cavidad abdominal se encontró una úlcera gástrica perforada; se realizó rafia primaria en dos planos, apendicectomía incidental, más lavado de cavidad abdominal. Paciente con recuperación exitosa, se indicó alta médica al séptimo día de hospitalización. CONCLUSIÓN: La perforación de una úlcera péptica puede generar un cuadro clínico de dolor en fosa ilíaca derecha, que puede confundirse con una apendicitis aguda debido a su similitud clínica. El equipo médico debe considerar al Síndrome de Valentino como un diagnóstico diferencial importante durante la evaluación del paciente que llega a la emergencia con cuadro clínico de dolor abdominal sugestivo de apendicitis aguda.

BACKGROUND: Valentino's syndrome is secondary to a perforated peptic ulcer, which could be located in the stomach or the duodenum, patients present with clinical features that suggest acute appendicitis, with localized peritonitis. There are few case reports about this syndrome worldwide and no one submitted in Ecuador. It is essential to transmit this clinical case for the knowledge of the medical- scientific community. CASE REPORT: A 63-year-old male patient came to the emergency department with abdominal pain, located in the right iliac fossa, that began 12 hours ago, associated to peritoneal irritation signs and hemodynamic decompensation; suggestive of peritonitis. An exploratory laparotomy was performed. EVOLUTION: During exploratory laparotomy, no inflammatory changes were identified in the appendix. After abdominal cavity exploration, a perforated gastric ulcer was found. Primary raffia was stitched in two planes, incidental appendectomy and lavage of the abdominal cavity were performed. The patient had a successful recovery; and was discharged after 7 days at hospitalization. CONCLUSION: The perforation of a peptic ulcer can generate right iliac fossa pain, simulating acute appendicitis due to its clinical similarity. The medical team should consider Valentino's Syndrome as an important differential diagnosis during the evaluation of a patient that arrives to the emergency room with abdominal pain, suggestive of appendicitis.

Age determination in subadults using histological analysis of bones / Determinación de la edad en subadultos usando análisis histológico de los huesos

Abstract Introduction: According to the literature, the amount of osteons has been suggested as a good proxy to determine the age of death in adults. However in subadults research has not been carried out yet. Objective: To determine the accuracy of the histomorphometric technique predicting the age at death in subadults using bone remains. Methodology: The information of static histomorphometric parameters from about 120 iliac bones retrieved from the exhumed remains of subadults whose age at death was known was taken from the Granada collection. In order to predict the age at death we performed a step by step linear regression to estimate the fittest model. Results: The most closely and significantly associated biopsy findings with age were: the osteon count, the internal cortical width, and the trabecular bone volume. Pearson's correlation index indicated a weak linear association among these variables. To assess the accuracy of the model we used a coefficient of determination with a 0.32 value. 32% of the age variation in the subadults was explained by the three variables. Conclusion: This regression model explains a percentage of the total age variation in the subadult population. However this model is not enough to determine the age at death.

Resumen Introducción: La capacidad de predicción de las osteonas para determinar la edad de muerte de los individuos ha sido descrito en la literatura científica. No obstante, no se ha determinado dicha capacidad en individuos subadultos. Objetivo: Determinar la eficacia de lo parámetros histomorfometricos en población subadulta. Metodología: Se realizaron biopsias de hueso ilíaco en los restos de 120 subadultos, de la Colección Osteológica de Granada, con edad conocida en el momento de la muerte. Para establecer la capacidad de predicción se utilizó el R2 obtenido a partir de regresión lineal múltiple. Resultados: Las variables con mayor nivel predictivo y significativo para la estimación de la edad fueron: recuento de osteonas tipo 2 de la cortical interna y externa, y el volumen óseo trabecular; En la evaluación del modelo, se obtuvo un coeficiente de determinación de 0.32, es decir, el 32% de la variación en la edad de los subadultos se explica por el modelo. Sin embargo, se evidenció diferencias en la capacidad de predicción por sexo. Conclusión: Este modelo de regresión explica un porcentaje sustancial de la varianza de la edad de los individuos en la muestra. No obstante, no es suficiente para garantizar una adecuada predicción de la edad al momento de muerte de los individuos subdultos.

Effect of Quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy treatment in patients with L 5, S 1 lumbar disc herniation / 中国修复重建外科杂志

Objective: To identify effect of quantitative indicators of ilium height on approach of percutaneous endoscopic lumbar discectomy (PELD) treatment in patients with L 5, S 1 lumbar disc herniation. Methods: A retrospective study between May 2014 and March 2016 was conducted, including 100 patients with disc herniation at L 5, S 1, who were initially enrolled for the PELD treatment. Among them, 66 patients were successfully treated with PELD (group A), and the other 34 patients failed to perform puncture, catheterization, or microscopical operation due to the influence of iliac bone and other peripheral bone structures and treated with alternative surgical plans. By analyzing the X-ray films of lumbar vertebrae (including bilateral ilium) of the two groups before operation, the concept of ilium height rate and ilium angle rate was put forward innovatively. The ilium height rate and ilium angle rate of the two groups were measured and compared, and the diagnostic critical points of ilium height rate and ilium angle rate were determined by ROC curve analysis. Results: The ilium height rate was 0.61±0.09, 0.74±0.05 and the ilium angle rate was 0.66±0.08, 0.80±0.08 in groups A and B, respectively, showing significant differences between the two groups ( F=69.729, P=0.000; F=65.165, P=0.000). ROC curve analysis showed that the critical point of ilium height rate was 0.71 (area under ROC curve was 0.927, P=0.000), and the critical point of ilium angle rate was 0.75 (area under ROC curve was 0.965, P=0.000). Conclusion: PELD is not recommended for patients with L 5, S 1 intervertebral disc herniation, when the ilium height rate is greater than 0.71 and/or the ilium angle rate is greater than 0.75. Other surgical plans such as transpedicular approach, transpedicular approach, or open surgery, should be recommended to reduce the risk of surgery and the pain of patients.

Application of anterior subcutaneous Internal Pelvic Fixation in pelvic anterior ring fracture: a meta analysis / 中华骨科杂志

Objective@#The related literatures on supra acetabular spinal pedicle screws and a subcutaneous connecting rod (INFIX) in recent years was reviewed, and the overall prognosis was analyzed by meta analysis.@*Methods@#literatures were obtained by searching the PubMed, Google Scholar, and Wanfang Full-text Database according to the criteria of inclusion and exclusion. The two members independently screened the qualified literature, evaluated the quality of the literature and extracted the data information. The data information includes demographic and surgical information, main results and secondary results. A large number of data in the selected articles were analyzed and summarized by meta.@*Results@#A total of 20 studies were included, including 567 patients. The clinical results were evaluated by Majeed standard in 6 articles, of which 5 articles described the number of excellent and general prognosis, including 185 patients. The excellent and good prognosis rate was 91% (95%CI: 80%-103%) by meta analysis. The general prognosis rate was 9% (95%CI: 3%-14%). Among the prognostic complications, the incidence of lateral femoral cutaneous nerve damage and heterotopic ossification was higher, and the incidence of other complications was less than 5%. There were 13 articles about the complications of ectopic ossification, of which 1 did not mention the specific number of asymptomatic heterotopic ossification, and the remaining 12 included 424 cases, including 132 cases of ectopic ossification. The incidence of ectopic ossification was 26% (95%CI: 11%-40%). Among the 567 cases, obvious symptoms of lateral femoral cutaneous nerve injury were reported. The patients with lateral femoral cutaneous nerve injury accounted for 25% (95%CI: 17%-32%), and the temporary nerve damage was found in 124 cases. The incidence of temporary agitation after subgroup analysis was 21% (95%CI: 14%-28%). Five articles mentioned the manifestations of postoperative femoral nerve damage, including 10 patients, the incidence of femoral nerve damage was 3% (95%CI: -1%-6%). A total of 18 articles on surgical site-related infections were reported, including 534 patients, of which 15 were infected, with an infection rate of 3% (95%CI: 2%-4%). 19 articles clearly reported the failure of internal fixation after INIFX operation, including 32 patients who needed reoperation for different reasons. The failure of internal fixation was 3% (95%CI: 2%-4%). A total of 585 cases of fracture non-prognosis data were reported, of which 473 cases were cured and 3 cases had bone nonunion. The non-union rate of fracture was 3% (95%CI: 1%-5%).@*Conclusion@#After InFix pelvic surgery, the patient's clinical follow-up prognosis score and imaging findings showed that the postoperative recovery was good, and the new technique also avoided the inconvenience and postoperative complications caused by many traditional pelvic external fixation techniques. However, it was also found that the lateral femoral cutaneous nerve damage and the incidence of heterotopic ossification were also higher.

Two different methods of free iliac flap grafting in the repair of tibial defect / 中华整形外科杂志

Objcetive@#To explore the treatment of long segment defect of tibia by using tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap.@*Methods@#From February 2012 to August 2017, The People′s Hospital of Zun Yi City Bo Zhou District treated 16 patients who had long segment defect of tibia.There were 11 males and 5 females, age from 22 to 58 years old, the average age was 42 years old. Iliac flap grafting with tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle was used to treat the defect of long segment of tibia. There were 4 cases with simple tibial defect and 12 cases with skin defect. The longest tibial defect was 5-8 cm.@*Results@#In this study, four patients used iliac flaps with deep circumflex iliac pedicle, the area of flaps ranged from 2.5 cm×5.0 cm to 5.0 cm×10.0 cm, while the area of iliac flaps ranged from 5.0 cm×2.5 cm to 8.0 cm×4.0 cm. Twelve patients used grafting with tensor fascia lata combined with iliac flap, the area of flaps ranged from 5.0 cm×12.0 cm to 12.0 cm×23.0 cm, while the area of iliac flaps ranged from 7.0 cm×2.0 cm to 8.0 cm×4.0 cm. All 16 cases of bone flap were survived, fracture healing, without surgical complications. The average follow-up period was 1.5 years, the flaps had good appearance in 10 cases and was slightly bloated in 6 cases; the ankle had normal motion in 14 cases and had poor dorsal extension in 2 cases. X-ray films showed that the bone flap repaired the bone defects and reached bone healing.@*Conclusions@#Vascularized tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap grafts increase local blood supply and accelerate the process of fracture healing.

An iliac-crest-preserving iliac wing bone graft harvesting technique / 中华骨科杂志

Objective@#To evaluate the clinical application effects of an iliac-crest-preserving iliac wing bone graft harvesting technique and the bone regenerative ability of the donor site after harvesting.@*Methods@#From January 2016 to June 2017, a series of 39 patients including 28 men and 11 women aged between 16 and 59 y (35±13 y in average) were prospectively collected to treat bone defects using the iliac-crest-preserving iliac wing bone graft harvesting technique. The patient cohort included 38 ipsilateral and 1 bilateral bone harvests taken from 15 femoral fracture non-unions, 8 tibial fracture non-unions, 11 femoral head necroses (hip preserving surgery), 1 tuberculosis deriving hip arthritis with bone defect (total hip arthroplasty), 2 hip prosthesis loosenings (revision), and 2 proximal femoral benign tumors. All patients were treated through comprehensive surgeries containing autologous iliac bone grafting. The surgical time, blood loss, bone graft volume, 24 h post-operative visual analogue scale (VSA) at the iliac surgical site, complications, and bone regeneration of the donor site were documented and evaluated.@*Results@#In the 39 patients (40 sides), the average surgical time was 25±4 min, average blood loss was 79±23 ml, average bone graft volume was 27±6 cm3. The average 24 h post-operative VAS at the iliac surgical site was 1.8±0.7 points. The VSA at the 6 week later and thereafter were 0 in all patients. The iliac incisions in 38 patients (39 sides) were healed uneventfully. However, seroma at the iliac surgical site emerged in 1 patient at the 6th post-operative day in the manner of serous exudation and was treated successfully with non-operative measures. None infections and lateral femoral cutaneous nerve injuries took place. Iatrogenic non-displaced iliac crest fractures happened in the very first 2 patients when taking the crest as a pivot to pry up the graft, which united without special cure at the 3 month post-operative. This complication was completely avoided when shifting the pivot to the anterior pillar containing the anterior iliac spines. None pelvic fractures and heterotopic ossifications took place. Post-operative radiographical examinations revealed that the bone defects at the donor site shrank through bone regeneration, that mamillary or canine-tooth-shaped bone formation occurred in some of the cases, and that none complete bone regeneration took place to eliminate the bone defect at the donor. There were 12 patients in whom pre- and post-operative computed tomographic scans necessitated by the disease were prescribed, which facilitated the measuring of the bone defect at the donor site. The measurement of 13 sides revealed that the bone defects were decreased more or less: the average immediate post-operative bone defect was 25.7±6.5 cm2, the average 12 month post-operative bone defect was 12.7±5.3 cm2.@*Conclusion@#The iliac wing bone graft harvesting technique suggested here is safe and less invasive, in the premise of preserving the iliac crest and retaining the figure of the surgical site, it can harvest a large amount of iliac wing bone graft and reserve the bone regenerative ability of the donor site

Finite element analysis of fixation of U-shaped sacral fractures / 生物医学工程学杂志

Finite element method (FEM) was used to investigate the biomechanical properties of three types of surgical fixations of U-shaped sacral fractures. Based on a previously established and validated complete lumbar-pelvic model, three models of surgical fixations of U-shaped sacral fractures were established: ① S1S2 passed through screw (S1S2), ② L4-L5 pedicle screw + screw for wing of ilium (L4L5 + IS), and ③ L4-L5 pedicle screw + S1 passed through screw + screw for wing of ilium (L4L5 + S1 + IS). A 400 N force acting vertically downward, along with torque of 7.5 N·m in different directions (anterior flexion, posterior extension, axial rotation, and axial lateral bending), was exerted on the upper surface of L4. Comparisons were made on differences in separation of the fracture gap and maximum stress in sitting and standing positions among three fixation methods. This study showed that: for values of separation of the fracture gap produced by different operation groups in different positions, L4L5 + S1 + IS was far less than L4L5 + IS and S1S2. For internal fixators, the maximum stress value produced was: L4L5 + IS > L4L5 + S1 + IS > S1S2. For the intervertebral disc, the maximum stress value produced by S1S2 is much larger than that of L4L5 + S1 + IS and L4L5 + IS. In a comprehensive consideration, L4L5 + S1 + IS could be prioritized for fixation of U-shaped sacral fractures. The objective of this research is to compare the biomechanical differences of three different internal fixation methods for U-shaped sacral fractures, for the reference of clinical operation.

Objective To investigate the effect of iliac flap pedicled with superficial circumflex iliac artery and sartorius in the treatment of femoral neck fracture of the young adults.Methods From April,2012 to March,2017,50 cadaveric lower limbs were injected with red latex,and the origin,diameter,course and distribution of the superficial circumflex iliac artery and arteries of the sartorius were observed.The iliac flap pedicled with superficial circumflex iliac artery and sartorius was used to treat the femoral neck fracture in young adults in 11 cases.There were 9 males and 2 females with an average age of 34.5(ranged from 16 to 54) years.The fractures were classified ac cording to Garden:4 cases of type Ⅲ and 7 cases of type Ⅳ.Regular outpatient follow-up was made.Results The superficial circumflex iliac artery originated from the femoral artery and the initial diameter was (1.2±0.3) mm.The length of the superficial circumflex iliac artery to the anterior superior iliac spine was (8.8±1.3) cm.The superficial circumflex iliac artery run to the anterior superior iliac spine and sent 1-3 periosteal branches into the iliac crest.The sartorius originates from the anterior superior iliac spine,and its proximal artery arises from the superficial circumflex iliac artery and the femoral artery.Link-pattern arterial anastomosises were formed in sartorius by branches of adja cent vascular pedicles,which nourished the ilium flap.All incisions healed by first intention.All cases were followedup from 16 to 42 months,with an average of 32.3 months.All fractures healed for 3-7 months,with an average of 4.6 months.No fracture nonunion,femoral head necrosis and other complications occurred.Harris hip scores was 93.02± 5.33.Seven cases were excellent and 4 cases were good.Conclusion The iliac flap pedicled with superficial cir cumflex iliac artery and sartorius has rich blood supply,easily performed conducive to promoting fracture healing,and reducing the occurrence of femoral head necrosis.It is an effective method for the treatment of femoral neck fracture in young adults.

An iliac-crest-preserving iliac wing bone graft harvesting technique / 中华骨科杂志

Objective To evaluate the clinical application effects of an iliac-crest-preserving iliac wing bone graft harvesting technique and the bone regenerative ability of the donor site after harvesting.Methods From January 2016 to June 2017,a series of 39 patients including 28 men and 11 women aged between 16 and 59 y (35± 13 y in average) were prospectively collected to treat bone defects using the iliac-crest-preserving iliac wing bone graft harvesting technique.The patient cohort included 38 ipsilateral and 1 bilateral bone harvests taken from 15 femoral fracture non-unions,8 tibial fracture non-unions,11 femoral head necroses (hip preserving surgery),1 tuberculosis deriving hip arthritis with bone defect (total hip arthroplasty),2 hip prosthesis loosenings (revision),and 2 proximal femoral benign tumors.All patients were treated through comprehensive surgeries containing autologous iliac bone grafting.The surgical time,blood loss,bone graft volume,24 h post-operative visual analogue scale (VSA) at the iliac surgical site,complications,and bone regeneration of the donor site were documented and evaluated.Results In the 39 patients (40 sides),the average surgical time was 25±4 min,average blood loss was 79±23 ml,average bone graft volume was 27±6 cm3.The average 24 h post-operative VAS at the iliac surgical site was 1.8±0.7 points.The VSA at the 6 week later and thereafter were 0 in all patients.The iliac incisions in 38 patients (39 sides) were healed uneventfully.However,seroma at the iliac surgical site emerged in 1 patient at the 6th post-operative day in the manner of serous exudation and was treated successfully with non-operative measures.None infections and lateral femoral cutaneous nerve injuries took place.Iatrogenic non-displaced iliac crest fractures happened in the very first 2 patients when taking the crest as a pivot to pry up the graft,which united without special cure at the 3 month post-operative.This complication was completely avoided when shifting the pivot to the anterior pillar containing the anterior iliac spines.None pelvic fractures and heterotopic ossifications took place.Post-operative radiographical examinations revealed that the bone defects at the donor site shrank through bone regeneration,that mamillary or canine-tooth-shaped bone formation occurred in some of the cases,and that none complete bone regeneration took place to eliminate the bone defect at the donor.There were 12 patients in whom pre-and post-operative computed tomographic scans necessitated by the disease were prescribed,which facilitated the measuring of the bone defect at the donor site.The measurement of 13 sides revealed that the bone defects were decreased more or less:the average immediate post-operative bone defect was 25.7±6.5 cm2,the average 12 month post-operative bone defect was 12.7±5.3 cm2.Conclusion The iliac wing bone graft harvesting technique suggested here is safe and less invasive,in the premise of preserving the iliac crest and retaining the figure of the surgical site,it can harvest a large amount of iliac wing bone graft and reserve the bone regenerative ability of the donor site.

ABSTRACT Objective: Evaluate the initial results and the possible complications of the combination of pelvic fixation using iliac screws in long instrumentations of the lumbar spine in elderly patients. Methods: An analysis of 38 patients who underwent lumbar spine arthrodesis instrumentation with more than 3 levels, in which we included level L5-S1 and extended the fixation to the iliac crest. Radiological assessment of instrumentation through X-ray of the lumbar spine and pelvis, and computed tomography, to investigate the presence of radiological fusion. Clinical evaluation through a questionnaire of buttock pain including the visual analogue pain score (VAS). Complications related to pelvic instrumentation were investigated. Results: All patients had radiological fusion in the lumbosacral transition. A halo was found around the iliac screw on imaging studies in 31% of patients, but without related symptoms. The questionnaire of buttock pain found that 15% of patients had some low intensity buttock pain (VAS 1-2) and no need to or interest in removing the screws. There was infection at the surgical site in 2% of cases, hematoma in the buttocks in 5%, and vertebral body fracture in the cranial level instrumented in 7% of cases. Conclusions: Pelvic fixation through the iliac screws proved to be effective in protecting the S1 screws in long instrumentations including the L5-S1 level in elderly patients, allowing the radiological bone fusion. The overall results for pain were satisfactory, based on a questionnaire of buttock pain. There are no signs of overload or degeneration of the sacroiliac joints in the early years after surgery. Level of Evidence IV; Case series - therapeutic study.

Pinzamiento femoroacetabular secundario a osteocondroma ilíaco solitario / Femoroacetabular impingement secondary to solitary iliac osteochondroma

El pinzamiento femoroacetabular provoca dolor agudo en la ingle anterior y limita la movilidad de la cadera. Es un síndrome clínico propiciado por una alteración en la anatomía ósea. Los osteocondromas son los principales tipos de tumores benignos, alteran la anatomía ósea y, según su localización, pueden generar dolor y pinzamiento. Este reporte de caso tuvo como objetivo el describir el tratamiento dado y la evolución clínica de un paciente con pinzamiento secundario a un osteocondroma ilíaco solitario. Se presenta un paciente masculino de 20 años con agudización de un dolor punzante y disminución en los arcos de movilidad en la articulación de la cadera derecha, sin mejoría con tratamiento sintomático. Mediante estudios de imagen se identificó una masa tumoral en la región afectada. Se realizó resección quirúrgica total mediante un abordaje lateral directo extendido de Hardinge. Dada la naturaleza benigna del tumor y su total resección, el paciente evolucionó satisfactoriamente y se pudo incorporar a sus actividades cotidianas. Se concluye que los osteocondromas no son exclusivos de las metáfisis o epífisis de huesos largos. Deben sospecharse las presentaciones atípicas cuando el cuadro clínico es sugestivo, aun después de la adolescencia(AU)

Femoroacetabular impingement generates acute pain in the anterior groin and limitation of hip mobility. It is a clinical syndrome caused by an alteration in bone anatomy. Osteochondromas are the main types of benign tumors, they alter the bone anatomy and depending on their location, they can generate pain and impingement. This case report aims to serve as a reference for specialized care in communicating the diagnostic challenges and approach in a patient with secondary clamping to osteochondroma of atypical presentation. The present case report aims to describe the given treatment and clinical evolution of a patients presenting femoroacetabular impingement secondary to a solitary osteochondroma. We report a 20-year-old male patient with exacerbation of a shooting pain and decrease in the mobility arches in his right hip joint, with no improvement with symptomatic treatment. Through imaging studies, a tumor mass was identified in the affected region. Total surgical resection was performed through an extended direct lateral approach of Hardinge. Given the benign nature of the tumor and its total resection, the patient evolved satisfactorily. The prognosis is favorable. He was able to return to his daily activities. We concluded that osteochondromas are not exclusive to the metaphysis or epiphyses of long bones. Atypical presentations should be suspected when clinical manifestations suggest so, even after adolescence(AU)

Le pincement fémoro-acétabulaire provoque une douleur aigue au niveau du bassin antérieur et empêche la mobilité de la hanche. Il s'agit d'un syndrome clinique poussé par une altération de l'anatomie osseuse. Les ostéochondromes sont des tumeurs bénignes, altérant l'anatomie osseuse et, selon leur localisation, pouvant même déclencher la douleur et le pincement. Ce rapport de cas a le but de décrire le traitement proposé et l'évolution clinique d'un patient atteint de pincement secondaire à un ostéochondrome iliaque solitaire. Un patient âgé de 20 ans souffrant la recrudescence d'une douleur aigue et la diminution des arcs de mobilité de l'articulation de la hanche droite, sans soulagement, même sous traitement symptomatique, est présenté. Une masse tumorale a été identifiée par imagerie dans la région affectée. On a effectué une résection chirurgicale totale par la voie d'abord latérale directe et étendue de Hardinge. Étant données la nature bénigne de la tumeur et sa totale résection, le patient a eu une évolution satisfaisante, et a pu s'incorporer aux activités de la vie quotidienne. On peut conclure que les ostéochondromes ne sont pas exclusifs de la métaphyse ou de l'épiphyse des os longs. On doit suspecter des présentations atypiques lorsque le tableau clinique est suggestif, même après l'adolescence(AU)

Chilotic Index- A Strong Determinant In Studying Sexual Dimorphism Of Dried Hip Bones In The Population Of North Andhra Pradesh

Aims and Objectives: To study the sexual dimorphism of dried human hip bone with respect to chilotic line andchilotic index (CI) and finding a cut off value for the chilotic index that will be accurate for identification of sexin the human hip bone.Materials and Methods: The study was undertaken with a sample size of 44 adult human dried hip bones from thedepartment of Anatomy GVP.I.H.C & MT, Visakhapatnam, Andhra Pradesh. The Chilotic line (sacral segment andpelvic segment) was measured using a Vernier calliper and chilotic index was calculated.Results: The chilotic index in male hip bones fall in the range of 102.77mm-139.46mm with a mean value of118.32mm and for females it lies in the range of 61.63mm – 98.17mm with a mean value of 84.84mm. This findingis statistically significant with p-value = <0.001.Conclusion: The total chilotic line in males is longer than in females and a cut off value of 100.48 is statistically100% correct in identification of a male and a female hip bone.

Efficacy of "over iliac crest method" for ultrasound-guided posterior lumbar plexus block: a comparison with manual palpation and sagittal positioning / 中华麻醉学杂志

Objective To evaluate the efficacy of "over iliac crest method" for ultrasound-guided posterior lumbar plexus block by comparing with manual palpation and sagittal positioning.Methods A total of 75 patients,aged 25-64 yr,weighing 42-90 kg,with body mass index of 17-32 kg/cm2,of American Society of Anesthesiologists physical status Ⅰ-Ⅲ,scheduled for elective lower extremity surgery under ultrasound-guided posterior lumbar plexus block combined with parasacral sciatic nerve block,were divided into 3 groups (n =25 each) using a random number table method:manual palpation group (group M),sagittal positioning group (group S) and "over iliac crest method" group (group O).Patients received ultrasound-guided posterior lumbar plexus block with in-plane technique using the corresponding positioning method in M,S and O groups.Successful blockade of each level was recorded at 30 min after injection.Time to determine the lumbar intervertebral space,puncture time for lumbar plexus block,the requirement for adjuvant drugs and block efficacy were recorded.The development of complications related to puncture and nerve block was also recorded.Results Compared with group M,the success rates of blockade at levels L1 and L2 were significantly increased,the success rates of blockade at levels L4 and L5 were decreased (P＜0.05),no significant difference was found in the success rate of blockade at level L3 (P＞0.05),the time to determine the lumbar intervertebral space was prolonged,and the requirement for adjuvant drugs was decreased during surgery in O and S groups,and the efficacy of block was significantly enhanced in group O (P＜0.05).Compared with group S,the success rates of blockade at levels L1 and L2 were significantly increased,the success rates of blockade at level L4 were decreased,the time to determine the lumbar intervertebral space was shortened (P＜0.05),and no significant change was found in the efficacy of block in group O (P＞0.05).There was no significant difference in the puncture time for lumbar plexus block between the three groups (P＞0.05).Complications related to puncture and nerve block were not found in three groups.Conclusion "Over iliac crest method" provides higher success rate and better efficacy than manual palpation and sagittal positioning when used for lumbar plexus block.
