ABSTRACT
Background@#Avascular necrosis (AVN) of the femoral head results from intraosseous pathology causing functional impairment. Early diagnosis allows conservative treatment like core decompression, delaying total hip arthroplasty.@*Objective@#This meta-analysis aims to summarize platelet-rich plasma's (PRP) impact as an adjunct to core decompression (CD) on treatment outcomes and femoral head preservation in hip AVN. @*Methods@#The study conducted a comprehensive literature search using PubMed, Cochrane Library, Science Direct, Google Scholar and Med Line, including randomized controlled trials (RCTs) and previous meta-analyses from various databases. Using a random effects model, it compared PRP+CD with bone grafting to CD with bone grafting alone in AVN patients, evaluating function, pain scores, disease progression and the need for hip surgery.@*Results@#The meta-analysis examined 1041 records and included three studies. The primary outcomes were function and pain scores using Harris Hip Scoring (HHS) and Visual Analog Scale (VAS). Postoperative HHS scores at final follow-up favored the PRP+CD group significantly over CD alone. Postoperative VAS scores showed a trend towards higher scores in the CD alone group. The PRP+CD group demonstrated higher survival from disease progression compared to CD alone. Overall, the study suggests that PRP+CD led to better functional outcomes and disease progression outcomes than CD alone in AVN of the hip.@*Conclusion@#The PRP+CD treatment group showed significant benefits in AVN patients compared to CD alone, including higher HHS scores, improved disease progression survival and reduced need for hip surgery. Although PRP+CD resulted in decreased VAS scores, the difference was not statistically significant.

ABSTRACT Half of the patients with systemic lupus erythematosus (SLE) will have a reduced bone density and more than one in ten will develop osteoporosis (OP) prematurely. Multiple risk factors have been related to loss of bone mass, but just a few are modifiable, such as adequate vitamin D and calcium intakes, weight bearing exercise, controlling SLE activity and limiting the use of glucocorticoids (GC). GC have also been strongly associated to osteonecrosis or avascular necrosis (AVN). The main consequences of OP and AVN are fractures, which lead to significant functional limitation, loss of quality of life and increased morbidity. OP-related fractures can be reduced by performing appropriate screening with bone densitometries and providing prophylactic treatment when long-term or high dose GC are needed. No formal screening is available for AVN; but diagnosis is made by imaging (X-ray, bone scan or advanced imaging where appropriate). Aiming for the lowest dose possible of GC in combination with immunosuppression as well as an early recognition of the symptoms will prevent further complications. This manuscript is a practical review of the epidemiology, pathophysiology, and management of OP and AVN in patients with SLE, based on the available evidence and guidelines.
RESUMEN La mitad de los pacientes con lupus eritematoso sistémico (LES) tendrá una densidad ósea disminuida, y más de uno de cada 10 desarrollará osteoporosis (OP) prematuramente. Son múltiples los factores de riesgo que se han relacionado con la pérdida de la masa ósea, pero solo unos pocos son modificables, tales como la ingesta de niveles adecuados de vitamina D y de calcio, ejercicio con pesas, controlar la actividad del LES, y limitar el uso de glucocorticoides (GC). También se ha encontrado una estrecha relación entre el uso de GC y osteonecrosis o a necrosis avascular (NAV). Las principales consecuencias de la OP y de la NAV son fracturas, que generan una limitación funcional importante, pérdida de la calidad de vida y aumento de la morbilidad. Las fracturas por osteoporosis se pueden reducir mediante un tamizaje adecuado con densitometría ósea y administrando tratamiento profiláctico cuando se requieren GC de largo plazo o a altas dosis. No existe un tamizaje formal para la NAV, pero su diagnóstico se realiza con imágenes (radiografía, gammagrafía ósea o imágenes avanzadas cuando corresponda). El apuntar a la menor dosis posible de GC, en combinación con inmunosupresión, además de la temprana identificación de los síntomas, ayudará a prevenir otras complicaciones. El presente artículo es una revisión práctica de la epidemiología, la fisiopatología y el manejo de la OP y la NAV en pacientes con LES, en función de la evidencia y de las guías disponibles.

Background: Neglected traumatic dislocation of the hip is extremely rare in children, and the preferred treatment remains unclear. In this study we studied the role of open reduction in neglected traumatic hip dislocation in children and adolescents as a modality of treatment.Methods: Eight patients with a neglected, traumatic dislocation of the hip received in the emergency department of GMC, Jammu were managed by open reduction. Types of dislocations, associated lesions, treatment methods, complications, and clinical and radiological outcomes were reviewed in the study.Results: All patients presented with limp and pain. Six patients had minimal difficulty in squatting while two had marked difficulty. Leg lengths were within 2 cm in 7 of 8 cases at follow-up, and only 1 patient had a discrepancy greater than 2 cm.Conclusions: Open reduction is a satisfactory treatment for neglected hip dislocation. It restores joint stability, range of motion and limb length.
ABSTRACT
Resumen: La presentación de una fractura de fémur proximal es totalmente diferente en pacientes jóvenes que en pacientes adultos. A diferencia de la fractura cerrada de fémur proximal, la incidencia de fracturas expuestas se encuentra en la población joven de entre 15 y 30 años de edad. Dentro de las complicaciones que podemos observar en estas fracturas se encuentra la osteonecrosis avascular (NAV) de la cabeza femoral, la cual se define como la interrupción del aporte sanguíneo a la cabeza femoral, ya sea por trauma, infección, alcoholismo o uso de esteroides, ocasionando necrosis ósea, colapso articular y osteoartrosis. El tratamiento dependerá de la presentación del caso, la edad del paciente y el tiempo en hacer el diagnostico. Se presenta el caso clínico de un paciente de 16 años de edad el cual ingresa al servicio de urgencias con diagnóstico de herida por arma de fuego a nivel de cadera izquierda. Se realiza lavado quirúrgico y reducción cerrada más fijación interna con clavo centro medular. Se da un seguimiento clínico y radiográfico por 3 años observando la evolución de la fractura y la subsecuente necrosis avascular que presenta el paciente.
Abstract: The clinical presentation of a proximal femoral fracture is completely different between young and adult patients. Unlike closed proximal femoral fractures, the incidence of exposed fractures is found in the young population between 15 and 30 years of age. Osteonecrosis of the femoral head is one the complications we can find in this type of fractures. Avascular necrosis (AVN or osteonecrosis) is defined as the interruption of blood supply to the femoral head due to trauma, infection, alcohol or steroid use, resulting in bone necrosis, joint collapse and osteoarthrosis. The treatment will depend on the clinical presentation, age of the patient and when the diagnosis is made. This is a case report of a 16-year-old patient with a gunshot wound on the hip. Surgical cleansing and closed reduction plus internal fixation with a nail in the center of the spine were performed. A 3-year clinical and radiographic follow up was made, observing the evolution of the fracture and the subsequent avascular necrosis that the patient presented.
ABSTRACT
Avascular necrosis (AVN), also called osteonecrosis, aseptic necrosis, or ischemic bone necrosis, is a condition that occurs when there is loss of blood supply to the bone, an interruption to the blood supply causes bone to die. If not stopped this process eventually cause the bone to collapse. It is the most challenging condition of the present era in orthopedics. In Ayurveda it can be co-related with the Asthi Majja Gata Vata due to similar sign and symptoms of Avascular necrosis of neck of femur. Aim and objectives: To assess the efficacy of Manjisthadi Kshara Basti, Rooksha Choorna Pinda Swedana, Pizhichil and Shastikashali Pinda Swedana in the management of AVN. Objective was to stop the further deterioration of the hip joint and to reduce the chances of surgical intervention in managing AVN. Materials and methods: A diagnosed and non operated case of Avascular necrosis of stage 3 with complaints of pain of bilateral hip joint, restricted movements and limping gait approached the out-patient division of the hospital and was managed by Rooksha Choorna Pinda Swedana, Manjisthadi Kshara Basti, Pizhichil and Shastikashali Pinda Swedana. Observation and Result: Significant improvement was noticed after the treatment. Pain was reduced significantly with improvement in range of movement. Patient was able to walk and climb stairs after the treatment without pain and stiffness. There was reduction in VAS scale, marked improvement was noticed in Harris Hip Score.
ABSTRACT
Background: Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply. Aim and objectives: To study the appearances of avascular necrosis at different sites using radiological modalities like: X-ray, MRI to diagnosis and evaluate AVN in order to do early management of the condition. Materials and methods: 86 cases of either strong suspicion or symptoms related to avascular necrosis at various sites were evaluated who came to Dhiraj Hospital with different radiological modalities like X-ray, MRI. Results: Out of total number of 86 patients who were diagnosed and evaluated for avascular necrosis at different sites on X-ray, MRI along with its association with trauma, steroids and alcohol; most common sites being femoral head, humoral head, lunate, tibial tubercle, scaphoid. Conclusion: Femoral head was the most common site affected with avascular necrosis with trauma being the most common risk factor. The sensitivity of detection of collapse of the involved bone and joint space narrowing was same for MRI and plain radiography. This findings were correlated for precollapse and post collapse state for avascular necrosis by MRI and X-ray
ABSTRACT
Introduction: The anatomy of the coronary arteries is fascinating and most varied. The aim of the present work was to study the gross anatomy of the right coronary artery (RCA) regarding its importance for interventional cardiologists and cardiac surgeons. Materials and Methods: The material of the present study included 30 preserved hearts obtained from the dissecting rooms of anatomy departments, Faculty of Medicine, Beirut Arab University and Alexandria University. Results: Present study revealed that the length of the first segment of RCA ranged from 5.7 to 8.0 cm with a mean of 6.3 ± 0.6 cm; Its external diameter ranged from 4.0 mm to 7.0 mm with a mean of 5.1 ± 0.7 mm. The length of the second segment of RCA ranged from 3.4 to 6.0 cm with a mean of 4.9 ± 0.7 cm; Its external diameter ranged from 3.1 mm to 5.6 mm with a mean of 4.3 ± 0.8 mm. The right conus artery was found to arise at a distance 0.5 to 2.4 cm with a mean of 1.5 ± 0.6 cm from the beginning of RCA. At a distance 0.6 cm to 2.6 cm with a mean of 1.6 ± 0.6 cm from its beginning, the RCA was found to give its SAN branch. At a distance 2.7 cm to 5.6 cm with a mean of 4.2 ± 0.8 cm from its beginning, the RCA was found to give its acute marginal branch. Whether it terminated at or beyond the cardiac crux, RCA was found to give origin to the posterior interventricular branch in all specimens. In all specimensthe AVN artery was found to arise from RCA at the region of cardiac crux. Myocardial bridging was recorded in 2 specimens. Conclusion: This study directs the attention towards the importance of the right coronary artery in the supply of the myocardium and the patterns obtained here may be clinically relevant during percutaneous coronary interventions or surgical revascularization.

Objective To find out factors related to avascular necrosis (AVN) of femoral head through a retrospective study of patients with femoral neck fractures treated with cannulated screws.Methods Two hundred and thirty cases of femoral neck fracture whn had been treated with cannulated screws in our department from August 1994 to October 2003 were analyzed statistically.Six factors of patient,age,gender,fracture type (Garden clas- sification),reduction method (close or open),the quality of reduction (Garden Index) and time interval from injury to surgery were analyzed statistically with rank sum test and logistic multiple regression.Results Factors that might have an impact on avascular necrosis of femoral head were ranked in the following likelihood sequence: fracture type,quality of reduction,reduction method,time interval from injury to surgery and age.Gender was found to have little impact on the prognosis of femoral neck fracture (P＞0.05).Conclusions Fracture displacement is the most critical factor that influences the prognosis.Anatomical reduction (close or open) must be achieved to re- duce the risk of AVN.Timing of surgery shows its importance.High age will not lead to an increased incidence of AVN.
ABSTRACT
The incidences of posttraumatic avascular necrosis of the femoral head were variably reported. In 1980, Calandruccio reported its incidence of 14% in nondisplaced femoral neck fracture and 50% in displaced ones. In general, the prophylactic methods, such as core decompression, bone graft and trochanteric osteotomy were recommended for the treatment of early stages of femoral head avascular necrosis(Ficat-Arlet stage 1 or 2), while the primary replacement surgery for the advanced ones (Ficat-Arlet stage 3 or 4). One of our authors(Y.K. Chung) has performed five cases of corticocancellous bone grafts using combined autogenous free fibular graft and iliac cancellous bone graft, for the post-traumatic femoral head AVN from January 1985 to December 1989 at our hospital, and the following results are obtained: 1. Among the forty nine displaced adult femoral neck fractures, there were five eases of avascular necrosis(10. 2%). 2. There were three male patients and two female ones, and the average age of injury was 48 years old(30 to 57). 3. According to the type of fractures, there were four cases of subcapital fracture and one of transcervical fracture. All of the patients were performed closed reduction and internal fixation with compression hip screw system, including additional Knowles pinning in two cases. 4. Histological study with the excised femoral head, showed that there was no bony union between the grafted cancellous bone and the necrotic head, and the grafted bone has been changed to amorphous necrotic tissue. However, we found a solid consolidation of the grafted bone and the femoral neck portion.

The exact etiologies and mechanisms of ischemia in avascular necrosis of femoral head are still under investigation. But this condition seems to be increasing during a few decades with increasing use of steroid and alcohol abuse in Korea. The treatment modalities have been based on the stages of the disease by simple radiographic findings that do not describe the accurate pathological extent or localization. Therefore more sophisticated study is needed to treat the AVN of the femoral head well. Magnetic resonance images, simple radiographs, scintigraphs of 13 patients(22 femoral heads), who were admitted and treated at Seoul National University Hospital from April, 1989 to December, 1989 were correlated, to characterize the type of AVN by extent and location regardless of its stage and reveal the relationship between types and stages. It is the result of this study that the type of AVN as well as stage should be considered in determining the treatment modality.
