ABSTRACT A morphologic study of the anterior part of the iliac crest was performed.
To define the anatomic characteristics of the anterior part of the ilium and to determine an optimal area to harvest the iliac bone graft from the anterior iliac crest.
Stress fracture or avulsion fracture of the anterior cut for anterior iliac crest graft have been noted previously. However, there is insufficient published information on the morphology of the anterior part of the ilium relative to the optimal location of harvesting the bone graft.
Direct measurements using digital calipers were taken from 30 dried human pelves and 10 cadaveric pelves. The thickness of the anterior part of the ilium was measured, with different starting points on the iliac crest. The length of the bicortical iliac bone graft also was determined.
The thickest portion of the ilium was 18.9 +/- 2.3 mm at the iliac tubercle, which was 45% thicker than at a point 3 cm posterior to the anterior superior iliac spine. The thick region of the anterior iliac crest extended 54.0 +/- 10.2 mm posteriorly from a point 3 cm posterior to the anterior superior iliac spine. The mean length of a 10 mm thick bicortical iliac tubercle bone graft was 36.8 +/- 8.7 mm.
The region around the iliac tubercle is suitable for harvesting bicortical or tricortical bone graft.

    ABSTRACT: OBJETIVO: evaluar las posibles compilaciones asociadas a la retirada del injerto de la cresta ilíaca anterior en cirugía para artrodesis cervical anterior, principalmente los dolores residuales. MÉTODOS: fue realizado un estudio retrospectivo con análisis de prontuarios y con aplicación de cuestionario por teléfono para 20 pacientes entre agosto de 2008 y noviembre de 2009. Todos los pacientes fueron sometidos al mismo procedimiento cirúrgico para la retirada del injerto, siendo que fueron operados por el mismo equipo en el Hospital de Clínicas de la Unicamp (HC Unicamp). Las variantes analizadas fueron: dolor residual, tasa de infección, lesión neurológica o vascular y aparición de fractura en el ala ilíaca. Los datos fueron colocados en una tabla, y las mediciones y porcentajes fueron calculados. RESULTADOS: de los 20 pacientes, 12 hombres y 8 mujeres, con edad media de 51,75 años (29-74), acompañamiento medio de 11,83 meses (2-29). No tuvo ninguna lesión grave como fractura, lesión arterial o neurológica. Hubo un caso de infección superficial (5%), y 25% de los pacientes se quejaron de malestar leve y dificultades para andar no incapacidad. CONCLUSIÓN: la retirada del injerto de la cresta ilíaca anterior esta relacionada a muchas complicaciones, siendo importante el conocimiento de otras opciones de injerto y exposición al paciente de las posibles complicaciones. A través del levantamiento, no se verificó ninguna complicación grave y el porcentual de pacientes con dolor residual pude se comparar con los encontrados en literatura, pudiendo ser reducidos a través de una disección cuidadosa de la cresta ilíaca.

    ABSTRACT: Anterior iliac crest bone is a widely used donor site for bone harvesting. It provides an autologous bone graft consisting of cancellous bone that can be packed or cortical bone with greater structural support. Uses include spinal fusion and fracture non-union surgery. Although its use is common, dedicated anatomical and radiological studies analysing graft dimensions and optimal harvesting site in relation to local anatomical landmarks [anterior superior iliac spine (ASIS), anterior iliac tubercle (AIT) and lateral femoral cutaneous nerve (LFCN)] have not been described. Twenty-eight female hemipelvises were dissected for this study. The LFCN, ASIS and AIT were identified. Calliper measurements and CT scan analysis were undertaken to determine the optimum positions in obtaining a 5-mm-thickness tricortical graft whilst remaining safe for the LFCN. According to our measurements, the optimal location for harvesting a 5-mm-thick tricortical graft with 35-mm height and 47-mm width is situated anterior to a line passing at the level of the thickest point of the AIT. This thickest point was situated at a mean 67 mm from the centre of the EIAS in our study. This anatomical and radiographic study determined the anatomical iliac crest landmarks to avoid neurological injury when taking an optimal 5-mm-width tricortical bone graft.

    ABSTRACT: This was a prospective randomized comparative study. The aim of this study was to objectify donor site-related pain following anterior iliac crest graft harvesting, in patients who have undergone multilevel anterior cervical discectomy and fusion with plating (ACDFP); and to assess the effect of an intraoperative local single injection of ropivacaine on postoperative pain. Multilevel ACDFP can be associated with a high non-union rate. Autogenous iliac bone has been used to increase union rates, although a high incidence of donor site-related pain has been reported. Forty consecutive patients who required 3-level or 4-level ACDFP were prospectively assessed for donor site-related pain. Pain levels were assessed daily for five days postoperative using the visual analog scale (VAS). Patients were randomly assigned to group A or B. In group A patients, 7-10 mL of ropivacaine (0.2%) was injected into the iliac crest after iliac crest graft harvesting. Morphine usage via patient controlled analgesia was calculated. At six months postoperative, patient complaints at the harvest site were documented. Patients were randomly assigned to group A or B. In group A, ropivacaine was locally administered at the site of the iliac crest graft harvest after fascia closure. In group B, no additional treatments were administered. The average patient age in group A was 56±7.6 years, whereas the average age of patients in group B was 52.6±10.4 years. Group A had an average of 0.6±0.7 previous surgeries per patient, whereas group B had an average of 0.8±1.0 previous surgeries per patient. The average number of levels fused in group A was 3.6±0.7, whereas the average number of levels fused in group B was 3.7±0.9 (all p>0.05). In group A, the mean ropivacaine volume administered was 8.4±1.5 mL. No patient complaints regarding chronic pain, were reported six months postoperatively. No complications were encountered from the harvest site, and all patients underwent successful 3-level and 4-level ACDFP. Statistical analysis showed significant differences for VAS on postoperative day 1 (p=0.004) and day 2 (p=0.005). VAS assessment showed overall moderate perioperative morbidity in terms of donor site-related pain, which was reduced by administering ropivacaine.
