Abstract
Background The anterior iliac crest is the workhorse for the harvest of cancellous bone in children undergoing cleft alveolar bone grafting. However, the complexity of the anatomy makes the process of harvesting graft technique sensitive. The aim was to describe the outcomes of the medially based trap door method of graft harvest in pediatric patients undergoing cleft alveolar bone grafting. Methods A cohort study was conducted, including all the patients in the age group of 8-12 years. Alveolar bone grafting was performed after harvesting a cancellous graft from the iliac crest bone grafting (ICBG) using a medially based trap door approach. Intraoperative time, average blood loss, and postoperative outcomes, including pain score, paresthesia, and gait disturbances, were recorded. Results A total of 28 patients were included in the study based on the inclusion and exclusion criteria. The volume of cancellous bone harvested was between 4-9 cc. The mean intraoperative time was 42 minutes, with an average blood loss of 36 to 48 ml. The average visual analog scale (VAS) score in the postoperative period was 3.5, 6, and 4 on the first, third, and seventh postoperative days. All the patients were ambulated on the second postoperative day, and none of them reported paresthesia. Long-term evaluation of the anterior illum revealed intact crestal morphology with a bone refill on the posterior-anterior (PA) pelvic X-ray. Conclusion A medially based modified trap door approach is more efficacious and less morbid for the harvest of ICBG in pediatric patients.

Kook I, You J, Kim DH, Park KC, Hwang KT. A retrospective cohort study of autogenous iliac strut bone grafting in large bone defects of the lower extremity. Sci Rep 2024; 14:6059. [PMID: 38480840 PMCID: PMC10937995 DOI: 10.1038/s41598-024-56726-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 03/11/2024] [Indexed: 03/17/2024] Open
Abstract
Autogenous iliac bone graft (AIBG) is the treatment of choice for managing bone defects, and favorable results have been reported for bone defects < 5 cm in length. In large bone defects ≥ 5 cm, it is difficult to obtain good results with simple bone grafting, and other management options have drawbacks, such as long immobilization periods and high complication rates. We hypothesized that AIBG in the strut form might show favorable results in large bone defects with minimal complications. This study aimed to investigate the outcomes of strut-type AIBG and evaluate its effectiveness compared to cancellous AIBG. This retrospective study included 50 patients who underwent AIBG for bone defects at a single institution between March 2011 and April 2020. We performed corticocancellous AIBG in a strut form to manage bone defects ≥ 5 cm in the lower extremities. The strut bone was harvested along the iliac crest and grafted slightly longer than the bone defect to apply a sufficient compressive force. Demographic information and radiographic and clinical results of patients who underwent strut AIBG (Group S) were analyzed. The outcomes of union, time to union, complications, and reoperation were compared with those of patients who underwent cancellous AIBG (Group C). The study population comprised 37 men (74%) and 13 women (26%), with a mean age of 50.0 (range: 19-78). The average follow-up period was 25.6 months (12-104 months). Group S included 16 patients with a mean bone defect length of 6.8 ± 1.2 cm. In Group S, union was achieved in all patients, with an average time to union of 6.7 months. Complications occurred in four cases, all related to wound problems. Group C comprised d 34 patients with a mean defect length of 2.8 ± 1.1 cm. Complications occurred in five patients in Group C, including four soft tissue problems and one implant failure. When comparing the outcomes of Groups S and C, no significant differences were observed. AIBG is an effective and safe technique for managing bone defects. Strut AIBG can be used effectively for bone defects ≥ 5 cm in the lower extremities.

Abstract
Anterior approach to the hip joint is commonly used for paediatric hip disorders. Lateral femoral cutaneous nerve (LFCN) is always exposed and dissected in this approach before deep dissection is carried out. The course of this nerve has been described in adults but there is a lack of literature regarding this in the paediatric age group. This study aimed to find the surgical anatomy of LFCN in children during the anterior approach to the hip. A total of 51 paediatric hip surgeries were done in 45 children for various hip disorders. The anterior exposure was done by the Somerville approach (Bikini incision). During surgical exposure, LFCN was exposed and its relationship to anterior superior iliac spine (ASIS), inguinal ligament and sartorius muscle was observed. In most of the cases (45/51) it was found as a single trunk below the inguinal ligament and medial to the ASIS. In one hip, multiple branches of the nerve were found just below the inguinal ligament. In four hip exposures, the nerve was not found in the surgical field and in one case nerve was accidentally cut during surgery as it was lying adherent to ASIS. There was no significant correlation between the observational parameters of the nerve with anthropometric variables. Nerve was mostly seen in area 5-25 mm medial to ASIS and 10-50 mm below the ASIS in 80% of our surgical exposures where the nerve was isolated. We observed that once LFCN is dissected, the injury during further surgical procedures can be prevented.

Abstract
BACKGROUND Meralgia paresthetica (MP) is an entrapment mononeuropathy of the lateral femoral cutaneous nerve (LFCN). Although structural abnormalities in nerve tissues can be confirmed using ultrasonography, this is not routinely performed.
CASE SUMMARY Herein, we present the case of a 52-year-old woman who developed MP after laparoscopic gynecological surgery. The patient was referred to our clinic from an obstetrics and gynecology clinic with symptoms of numbness and a tingling sensation in the left anterolateral thigh, which developed after surgery performed 5 mo earlier. Tests were performed to assess the disease status and determine the underlying causes. Ultrasonographic examination revealed an anatomical variation, where the left LFCN was entrapped within the inguinal ligament. This case suggests that performing ultrasonographic examination before and after surgery in the lithotomy position could help prevent MP.
CONCLUSION This case demonstrates the value of ultrasonography in detecting anatomical variation and diagnosing persistent MP. Ultrasonography should be considered an adjunct to electromyography for optimal MP management. Further, this case would help other clinicians determine patient prognosis and decide on targeted treatment strategies.

Abstract
PURPOSE To compare donor-site morbidity for alveolar bone grafting results following cartilage-preserving outer and inner cortico-cancellous iliac crest (OCIC and ICIC) bone block grafting in children. MATERIALS AND METHODS Patients were randomly divided into two groups and prospectively reviewed. In the OCIC and ICIC groups, cortico-cancellous bone blocks were harvested at outer and inner iliac crest respectively. Patient characteristics and surgical parameters were compared; pain intensity and duration, lateral femoral cutaneous nerve (LFCN) injury, gait disturbance, scar and contour satisfaction were analysed postoperatively. RESULTS Forty-nine consecutive patients (OCIC, 24; ICIC, 25) were included. There were no significant differences in patient characteristics or donor-site surgical parameters. The mean pain score on the first post-operative day was significantly lower in the OCIC group (3.75±1.70) than in the ICIC group (5.20±2.08) (p=0.012). The pain duration was similar in the two groups (median: 5 days). Temporary LFCN injury only occurred in 3 patients in the ICIC group. Postoperatively, the duck and circle gaits were observed in the OCIC and ICIC groups, respectively. There were no significant differences in the claudication duration, scar and contour satisfaction between the groups. CONCLUSION OCIC bone graft harvesting is marginally advantageous in children due to less early postoperative donor-site pain and a lower risk of nerve damage.

Abstract
BACKGROUND The purpose of this study was to investigate the effect of anterior superior iliac spine (ASIS) preservation on donor site morbidity and function after harvesting a vascularized iliac bone flap (VIBF). METHODS Patients who underwent jaws reconstruction with VIBF were divided into a maintaining the anterior superior iliac spine (MASIS) group and a not maintaining the anterior superior iliac spine (NMASIS) group. Pain, tenderness, sensory deficit, gait disturbance, and function of the donor site were evaluated before and after the operation. RESULTS Thirty-three patients were included in this study, of which 18 were in the MASIS group. The incidence of sensory deficit in the MASIS group was significantly lower than that in the NMASIS group (50.0% vs. 86.7%, p = 0.010). Pain, tenderness, gait disturbance, and function did not differ statistically between the two groups. CONCLUSION Except for sensory deficit, ASIS preservation has minimal impact on donor site morbidity and function.

Abstract
OBJECTIVE To evaluate the effect and summarize the characteristics of different treatment methods in repairing zygomatic defect. METHODS A total of 37 patients with zygomatic defect were reviewed in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from August 2012 to August 2019. According to the anatomical scope of defect, the zygomatic defects were divided into four categories: Class 0, the defect did not involve changes in zygomatic structure or continuity, only deficiency in thickness or projection; Class Ⅰ, defect was located in the zygomatic body or involved only one process; Class Ⅱ, a single defect involved two processes; Class Ⅲa, referred to a single defect involving three processes and above; Class Ⅲb, referred to zygomatic defects associated with large maxillary defects. The etiology, defect time, defect size and characteristics of zygomatic defects, the repair and reconstruction methods, and postoperative complications were collected and analyzed. Postoperative computed tomography (CT) data were collected to evaluate the outcome of zygomatic protrusion. Chromatographic analysis was used to assess the postoperative stability. RESULTS Among the causes of defects, 25 cases (67.57%) were caused by trauma, and 11 cases (29.73%) were of surgical defects following tumor resection. We performed autologous bone grafts in 19 cases, 6 cases underwent vascularized tissue flap, 5 cases underwent external implants alone, and 7 cases underwent vascularized tissue flap combined with external implants. After the recovery of the affected side, the average difference of the zygomatic projection between the navigation group and the non-navigation group was 0.45 mm (0.20-2.50 mm) and 1.60 mm (0.10-2.90 mm), with a significant difference (P=0.045). Two patients repaired with titanium mesh combined with anterolateral thigh flap had obvious deformation or fracture of titanium mesh; 2 patients with customized casting prosthesis had infection after surgery and fetched out the prosthesis finally. CONCLUSION Autologous free grafts or alloplastic materials may be used in cases without significant structural changes. Pedicle skull flap or vascularized bone tissue flap is recommended for zygomatic bone defects with bone pillar destruction, chronic inflammation, oral and nasal communication or significant soft tissue insufficiency. Titanium mesh can be used to repair a large defect of zygomatic bone, and it is suggested to combine with vascularized bone flap transplantation.

Abstract
Background: Autogenous bone grafts remain the “gold standard” in maxillofacial reconstructive procedures. The objective of this study was to evaluate the proximal tibia as a donor site of cancellous bone for bone grafting procedures of the mandible on the basis of intraoperative parameters and clinical observations. Methods: The study was based on a medical record search of 40 patients who underwent surgical procedures because of benign pathological lesions of the jaws resulting in 3-wall bone defects of the mandible and qualified for surgical removal of the lesion with simultaneous bone grafting of the defect with autogenous cancellous bone harvested from the proximal tibia. Results: The use of the proximal tibia for bone grafting procedures enables large amounts of cancellous bone (15.09 cc in average) to be obtained. The procedure is characterized by a low risk of early and late complications, which include excessive bleeding, wound infection, lengthy healing time, scars, a loss of sensation around the scars, aching, a dip in bone, swelling and tenderness. Conclusions: The ability to obtain large amounts of cancellous bone and a low risk of intra- and postoperative complications make the proximal tibia an attractive donor site for the bone grafting procedures in maxillofacial surgery.

Abstract
ABSTRACT Management of residual clefts of the alveolus and maxilla requires the coordinated effort of multiple members of the craniofacial team including surgeon, orthodontist, and when teeth are hypoplastic or absent, the prosthodontist to achieve complete habilitation. Such cooperation among specialists begins early in the patient's life and continues through completion of care.Although numerous publications on this topic exist, few present definitive multidisciplinary reconstructive outcomes with longterm results. In this review paper, the authors present our comprehensive, multidisciplinary protocols, experience, and techniques as they have evolved with over 35 years of practice at our Craniofacial Center.Details of our updated protocols for each intervention and procedure, including our current thoughts on appropriate timing, follow up and advantages from the incorporation of current technologies are discussed. Close cooperation among specialists at all stages of care, the use of evolving technology, and adherence to, and modification where indicated, of time honored team protocols enables us to consistently achieve successful functional and esthetic outcomes, while minimizing complications.

Abstract
Ultrasound (US) is commonly used to evaluate the cutaneous innervation of the lower extremity, owing to the following advantages: (1) US is a high-resolution soft tissue imaging modality; (2) it is feasible in patients who are deemed unsuitable to undergo magnetic resonance imaging; and (3) it enables dynamic and real-time imaging. The evaluation of cutaneous nerves requires accurate knowledge of the anatomy as well as technical details. We present a review of the US anatomy of the cutaneous nerves in the lower extremity in addition to a description of a few pathologic conditions.

Abstract
BACKGROUND Laparoscopic triple neurectomy is an available treatment option for chronic groin pain, but a poor working knowledge of the retroperitoneal neuroanatomy makes it an unsafe technique. OBJECT Describe the retroperitoneal course of iliohypogastric, ilioinguinal, lateral femoral cutaneous and genitofemoral nerves, to guide the surgeon who operates in this region. METHODS Fifty adult cadavers were dissected resulting in 100 anatomic specimens. Additionally, 30 patients were operated for refractory chronic inguinal pain, using laparoscopic triple neurectomy. All operations and dissections were photographed. Measurements were made between the nerves of the lumbar plexus and various landmarks: interneural distances in a vertical midline plane, posterior or anterior iliac spine and branch presentation model. RESULTS The ilioinguinal and iliohypogastric nerves were independent in 78% (Type II) and separated by an average of 2.5 ± 0.8 cm. In surgery study, only 38% were recognized as Type II and at a significantly greater distance (3.5 ± 1.2 cm, p < 0.001). The distance between ilioinguinal and lateral femoral cutaneous nerves was also greater during surgery, with statistical significance (5.1 ± 1.5 versus 4.2 ± 1.5, p < 0.005). The distance of the nerves to their bone references were not statistically different. The genitofemoral nerve emerged from the psoas major muscle in 20% as two separate branches (Type II), regardless of the study. The lateral femoral cutaneous nerve had a mean distance of 0.98 ± 1.6 cm medial to the anterior superior iliac spine. CONCLUSION The identification of the IH, II, FC and GF nerves is essential to reduce the rate of failures in the treatment of CGP. The frequent anatomical variations of the lumbar plexus nerves make knowledge of their courses in the retroperitoneal space essential to ensure safe surgery. The location of the nerves in the LTN is distorted by up to 1 cm. regarding references in the cadavers.

Abstract
Injury to the lateral femoral cutaneous nerve (LFCN) from compression or entrapment may result in meralgia paresthetica, a painful mononeuropathy of the anterolateral thigh. Surgical decompression of the LFCN may provide relief when conservative management fails. However, the considerable anatomic variability of this nerve may complicate surgical localization and thus prolong operative time. Herein, we report the use of preoperative high-resolution ultrasonography to map the LFCN in a patient with bilateral meralgia paresthetica. This simple, noninvasive imaging technique was seen to be effective at providing precise localization of the entrapped and, in this case, bilateral anatomically variant nerves. Preoperative high-resolution ultrasound mapping of the LCFN can be used to facilitate precise operative localization in the treatment of bilateral meralgia paresthetica. This is especially useful in the setting of suspected unusual nerve anatomy.

Abstract
The feasibility of three-dimensional (3D) printing technology combined with minimally invasive surgery in the treatment of pubic rami fractures was explored. From August 2015 to October 2017, a series of 30 patients who underwent surgical stabilization of their anterior pelvic ring (all utilizing the 3D printing technology) by one surgeon at a single hospital were studied. The minimally invasive incisions were made through anterior inferior cilia spine and pubic nodule. Data collected included the operative duration, the blood loss, the damage of the important tissue, the biographic union and the recovery of the function after the operation. Measurements on inlet and outlet pelvic cardiograph were made immediately post-operation and at all follow-up clinic visits. The scores of reduction and function were measured during follow-up. Results showed that the wounds of 30 patients were healed in the first stage, and there was no injury of important structures such as blood vessels and nerves. According to the Matta criteria, excellent effectiveness was obtained in 22 cases and good in 8 cases. According to the functional evaluation criteria of Majeed, excellent effectiveness was obtained in 21 cases and good in 9 cases. It was suggested that the 3D printing technology assisted by minimally invasive surgery can better evaluate the pelvic fracture before operation, which was helpful in plate modeling, and can shorten surgery duration and reduce intraoperative blood loss and complications. The positioning accuracy was improved, and better surgical result was finally achieved.

Abstract
Meralgia paresthetica (MP) is an entrapment neuropathy of the lateral femoral cutaneous nerve (LFCN). There are many variations in the course of the LFCN. A 55-year-old woman presented with pain and tingling sensations on the anterolateral aspect of her left thigh. Physical examination revealed hypoesthesia of the proximal anterolateral thigh on the left side. During the electrodiagnostic study, sensory nerve action potential of the LFCN could not be obtained on both sides. Through those clinical and electrophysiological findings, we prediagnosed the case as MP and planned to perform diagnostic nerve block. For the injection to perform, ultrasonography was used. During the ultrasonographic evaluation, the left LFCN was visualized lateral to the anterior superior iliac spine (ASIS). Then ultrasound-guided nerve block with 2 cc lidocaine 2% for diagnostic purpose was performed in this region. Immediately after the injection, the patient's complaints relieved completely, and hence the patient was diagnosed as having MP with an LFCN anatomical variation. Two months later her complaints persisted, and ultrasound-guided LFCN injection with 2 mL of lidocaine 2% + 1 cc of betametazone was performed. One month after the second injection, her complaints were relieved markedly and she resumed her daily activities. In conclusion, the course of the LFCN is quite variable. We present a relatively rare anatomical variation of the LFCN, crossing lateral to the ASIS, diagnosed with ultrasonography. Ultrasonography can be performed to visualize the LFCN, especially a nerve with an anatomical variation.

Abstract
Iliac particulate cancellous bone and marrow (PCBM) is still the most predictable autogenous graft material for vertical ridge reconstruction because of its high cell content as well as osteoinductive and osteoconductive properties. However, postoperative meralgia paresthetica, gait disturbance, pain, and bleeding have been reported following conventional harvesting from the anterior iliac crest. We present a case of minimally invasive harvesting of iliac PCBM. A short incision was made, and the iliac crest was exposed after elevation of the periosteal membrane. Only the iliac cortical bone was removed using a trephine bur to avoid perforation. PCBM was harvested with hand curettes and grafted into the vertical ridge defect. Because of the small surgical field, gait disturbance was resolved within 1 day without other postoperative complications. This technique is potentially useful for harvesting a small amount of iliac PCBM.

Indications of Free Grafts in Mandibular Reconstruction, after Removing Benign Tumors: Treatment Algorithm. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2016; 4:e845. [PMID: 27622113 PMCID: PMC5010336 DOI: 10.1097/gox.0000000000000832] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Accepted: 06/01/2016] [Indexed: 11/25/2022]
Abstract
Background: Mandibular reconstruction has been the subject of much debate and research in the fields of maxillofacial surgery and head and neck surgery. Materials and Methods: A retrospective observational study was undertaken with 14 patients diagnosed with benign tumorous pathologies and who underwent immediate mandibular resection and reconstruction at the Hospital del Salvador Maxillofacial Surgery Unit and Dr. Rodrigo Fariña’s private clinic between the years 2002 and 2012. We propose a treatment algorithm, which is previous teeth extractions in area that will be removed. Results: Fourteen patients underwent surgery, and a total of 40 dental implants were installed in 6 men and 8 women, the mean age of 33.5 (age range, 14–58 y). Reconstruction with iliac crest bone graft, and rehabilitation following this protocol (average of reconstruction was 8.7 cm), was successful with no complications at all in 12 patients. One patient had a minor complication, and the graft was partially reabsorbed because of communication of the graft with the oral cavity. This complication did not impede rehabilitation with dental implants. Another patient suffered the total loss of the graft due to infection because of dehiscence of oral mucosa and great communication with the mouth. Another iliac crest free graft reconstruction was undertaken 6 months later. Conclusions: The scientific evidence suggests that mandibular reconstruction using free grafts following the removal of benign tumors is a biologically sustainable alternative. The critical factor to improve the prognosis of free grafts reconstruction in benign tumors is to have good quality soft tissue and avoid communication with the oral cavity. For this, it is vital to do dental extractions before removing the tumor.

Abstract
Purpose Several variations in the anatomy and injury of the lateral femoral cutaneous nerve (LFCN) have been studied since 1885. The aim of our study was to analyze the available data on the LFCN and find a true prevalence to help in the planning and execution of surgical procedures in the area of the pelvis, namely inguinal hernia repair. Methods A search of the major medical databases was performed for LFCN anatomy. The anatomical data were collected and analyzed. Results Twenty-four studies (n = 1,720) were included. The most common pattern of the LFCN exiting the pelvis was medial to the Sartorius as a single branch. When it exited in this pattern, it did so on average 1.90 cm medial to the anterior superior iliac spine (ASIS). Conclusions The LFCN and its variations are important to consider especially during inguinal hernia repair, abdominoplasty, and iliac bone grafting. We suggest maintaining a distance of 3 cm or more from the ASIS when operating to prevent injury to the LFCN.

Abstract
OBJECTIVE We describe 2 patients with surgical injury to the lateral femoral cutaneous nerve (LFCN) after bone harvesting from the iliac crest for autologous bone grafting. DESIGN A case-series of 2 patients and literature study of all anatomical variants of the LFCN in relation to the anterior superior iliac spine and inguinal ligament. SETTING A teaching hospital in The Hague, the Netherlands. PATIENTS Two patients with surgical injury to the LFCN after bone harvesting from the iliac crest for autologous bone grafting. RESULTS All 9 known anatomical variations of the LFCN in the literature are reviewed, and the importance of these anatomical variations for surgeons and anesthetists is stressed. CONCLUSIONS For every trauma, orthopedic, plastic, and cranio-maxillofacial surgeon and anesthesiologist it is important to know the anatomy of the LFCN and its known variations. To prevent injury of the LFCN during bone harvesting, the bone should be harvested 4-5 cm posterior to the anterior superior iliac spine and the incision should be parallel to the iliac crest.

Abstract
INTRODUCTION The use of autogenous bone graft for Secondary alveolar bone grafting is well established in the treatment of cleft lip and palate patients. AIMS AND OBJECTIVES To evaluate post-operative morbidity of anterior iliac crest graft after secondary alveolar bone grafting in cleft patients. MATERIAL AND METHODS Forty patients during the period from July 2008 to March 2013, who underwent secondary alveolar bone grafting by harvesting graft from anterior iliac crest in Mamata Dental Hospital, Khammam, Andhra Pradesh, India are included in the present study. Unilateral and bilateral cleft patients who had undergone secondary alveolar bone grafting (SABG) with anterior iliac crest as their donor site have been selected and post- operative complications from the surgery were evaluated with the help of a questionnaire which included pain, gait disturbances, numbness and scar problems (infection, irritation). RESULTS Patients who were operated gave maximum score for pain as 8 on visual analogue scale. No pain was observed in any of the cases after 8 days, gait disturbances were seen in all patients (limping) for 2-6 days, there was no post-operative numbness with all the patients returning to their routine in 6- 15 days and 90% of the patients gave a satisfied response towards scar. CONCLUSION From the results in our study the morbidity after harvesting bone from iliac crest was found to be moderate to low, which had minimal complications and were well tolerated and greater acceptance from the patient.

Abstract
PURPOSE 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. METHODS 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. RESULTS 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. CONCLUSION 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
A total of eight cases with multiple skin defects of the hand and digits were resurfaced using a free iliac flap. The lesions involved both the hand and multiple digits in five patients and multiple digits in three patients. The average skin flap size was 89.3 cm(2). In three, a piece of of vascularized iliac bone was included. There was no flap loss. Flap debulking was performed in five patients at 10-12 weeks post-surgery during the operation for flap separation and inset. Secondary flap debulking was performed in one patient at 6 months post-surgery. The average static 2-point discrimination was 15.4 mm in five patients, whereas the remaining patients only exhibited sensation to pressure. This procedure may require additional refinement; however, the free iliac flap with technical refinements is a viable option for the treatment of multiple skin defects of the hand and digits.

Abstract
PURPOSE This study evaluated and compared the long-term donor-site morbidity of the free fibula flap with the deep circumflex iliac artery (DCIA) flap in maxillofacial reconstruction. MATERIALS AND METHODS Thirty-four patients (19 in the fibula group and 15 in the DCIA group) were evaluated for long-term morbidity. All clinical data were analyzed, including primary disease, type of defect, type of flap, length of bone harvested, total blood loss, operating time, length of hospitalization, and postoperative unaided gait. Subjective evaluation included cosmesis, function, and pain. Objective evaluation included physical examination, neurosensory assessment, Stony Brook Scar Evaluation, gait assessment, and goniometric measurement of range of movement. RESULTS In the subjective evaluation, no significant differences in cosmetic outcome, functional loss, wound healing, or pain between the 2 groups were noted (P > .05). However, neurosensory deficit was worse in the DCIA group (P ≤ .05). In the objective evaluation, 4 patients (27%) in the DCIA group had neurosensory deficit in the lateral thigh region. The DCIA group had a better Stony Brook Scar score (median, 5) than the fibula group (median, 4; P ≤ .05). However, there was no difference in walking ability between the 2 groups (P > .05). Goniometric measurement showed a significant difference between the operated and unoperated sites in the 2 groups; however, it was not severe enough in either group to affect patients' function. In the fibula group, 7 patients (38.9%) had claw toe deformity and 2 patients (12.1%) had weakness of the great toe, and the mean American Orthopedic Foot and Ankle Society score was 96.89. In the DCIA group, 1 patient (8.3%) had a hernia and the mean Harris Hip score was 98.33. CONCLUSION Given that these 2 options present donor-site concerns, the authors consider the fibula free flap the first choice for maxillofacial reconstruction in most cases and the DCIA free flap a reliable complementary flap in selected patients.

Abstract
OBJECTIVES To determine what anatomic structures are at risk after the application of a subcutaneous anterior pelvic internal fixator (APIF), from an incision over the anterior iliac crest to an incision centered over the pubic symphysis (Pfannenstiel). METHODS A laboratory investigation was performed using 5 fresh, frozen, nonpreserved cadaveric specimens (3 male specimens, 2 female specimens). Dissections were carried out to identify the relationships and proximity between the fixator screw constructs and various anatomic structures, including the (1) lateral femoral cutaneous nerve (LFCN), (2) ilioinguinal nerve (IIN), (3) iliohypogastric nerve (IHN), (4) femoral nerve, (5) femoral artery, (6) femoral vein, (7) genitofemoral nerve; and (8) spermatic cord or round ligament. The mean and range of distance from each of these structures to the implant were measured with calipers. RESULTS Despite variations in pelvic anatomy and width of pelvic brims, precontoured fixators (3.5 locking reconstruction plates) did not violate any pelvic neurovascular structures using this recommended application of an APIF. The spermatic cord was easily avoided as they were directly visualized using our application technique (mean, 0.4 cm, range, 0-2 cm). Abdominal musculature protected the IHN and IIN for most of their course, with the precontoured plates remaining inferior to their course and resting superficial to their branches (IHN mean, 1.5 cm, range, 1.2-1.8 cm and IIN mean, 2.1 cm, range, 0.9-4 cm). The LFCN traveled safely posterior to the inguinal ligament, thus being bridged by the internal spanning fixation without visualized disruption, impingement, or violation (mean, 1.5 cm, range, 0.6-4 cm). Finally, the femoral nerve, artery, and vein collectively demonstrated safe distance from the risk of compression (mean, 2.2 cm, range, 0.8-3.7 cm). CONCLUSIONS The anatomic structures hypothesized to be potentially endangered because of the lack of direct visualization during APIF placement, include the LFCN, IIN, IHN, femoral nerve, femoral artery, and femoral vein. Based upon our anatomic study, APIF, which may be used for treatment augmentation of anterior pelvic ring disruptions, does not place these structures at significant risk. In addition, the reproductive structures (round ligament and spermatic cord) are in direct visualization and can easily be avoided during implant placement.

Four-corner arthrodesis--does the source of graft affect bony union rate? Iliac crest versus distal radius bone graft. J Plast Reconstr Aesthet Surg 2011; 65:379-83. [PMID: 22015143 DOI: 10.1016/j.bjps.2011.09.043] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2011] [Revised: 09/07/2011] [Accepted: 09/27/2011] [Indexed: 12/21/2022]
Abstract
Four-corner arthrodesis is an accepted surgical option for treatment of scapholunate advanced collapse, scaphoid non-union advanced collapse and midcarpal instability. A preferred source of bone graft for performing four-corner arthrodesis is the iliac crest. An alternative and more convenient donor site is the distal radius. The aim of this study was to investigate whether the union rate after four-corner arthrodesis is influenced by the source of bone graft, that is, iliac crest or distal radius. In a retrospective analysis, charts and radiographs of 180 patients were identified. In 109 patients, iliac crest bone grafts were used, whereas 71 patients received distal radius bone grafts. In the iliac crest bone graft group, 101 out of 109 patients obtained a solid radiographic union of the arthrodesis at an average of 10 weeks after surgery, and non-union in eight patients (7.3%). In the distal radius bone graft group, X-rays of 66 patients showed bone union after an average of 10 weeks after surgery as well and five patients with non-union (7.0%) respectively. There was no statistical difference in bone union. Our data show that distal radius bone graft compares equally to iliac crest bone graft in performing four-corner arthrodesis. The advantages of the distal radius bone graft include a minor surgical exposure and the avoidance of using a distant anatomic site with associated donor-site morbidity.

Abstract
BACKGROUND The lateral femoral cutaneous nerve (LFCN) can be at risk during, for example, the insertion of pins in the anterior superior iliac spine (ASIS) during external fixation of the pelvis, total hip arthroplasty through a direct anterior approach, open surgery for impingement in the hip through an anterior approach, and periacetabular osteotomy. During surgery, the surgeon usually assumes the location of the LFCN by using the ASIS as a landmark. QUESTIONS/PURPOSES We investigated (1) whether there is any relationship between the LFCN and the ASIS and (2) the anatomy of the LFCN at the lateral border of the psoas major. METHODS Using 25 formalin-fixed cadavers, we determined the location of the LFCN emergence point as above, same level with, or below the iliac crest (IC). We measured the distances between the LFCN emergence point and the crossing of the IC and psoas major, ASIS, and pubic tubercle. We measured the distances between the ASIS and pubic tubercle (AB) and the ASIS and the point where the LFCN crossed the inguinal ligament (AC) and then calculated AC/AB. RESULTS The LFCN was below the IC on 19 sides, at the same level on 13 sides, and above on 12 sides. The distances were -0.98 ± 5.57 cm to the IC, 12.39 ± 2.67 cm to the ASIS, and 17.76 ± 3.33 cm to the pubic tubercle. AB was 13.11 ± 1.08 cm, AC 2.95 ± 2.01 cm, and AC/AB 0.22 ± 0.16. CONCLUSIONS/CLINICAL RELEVANCE The LFCN may emerge from the lateral border of the psoas major above or below the IC. The AC/AB ratio can help surgeons to find the LFCN in patients with different body types.

Abstract
OBJECTIVES To study the main anatomical landmarks related to the lateral cutaneous nerve of the thigh (LCN) in the infrainguinal region and to define reliable criteria for identifying the nerve during the surgery and electrophysiological study. METHODS Bilateral dissections of 60 adult non-fixed cadavers were performed with measurements of the distance between the inferior border of the anterior superior iliac spine (ASIS) and the LCN (DAL) and the internal angle between the LCN and the inguinal ligament (IA). The number of nerves exiting the inguinal ligament, the position of the LCN relative to the ASIS and to inguinal ligament were observed and registered. A triangle was designed using the inguinal ligament, the ASIS and the direction of tendinous insertions of the tensor of fascia lata muscle as parameters and the nerves were tested according its localization inside the triangle in each dissection. RESULTS In 80% of the dissections, the LCN passed under the inguinal ligament and was identified lateral to ASIS in only three dissections. A great variability was observed in the values of DAL and IA. The values of DAL ranged from 0 (immediately medial to ASIS) to 5 cm on either side with means of 1.31 and 1.22 cm on the right and left side, respectively. The values of IA ranged from 40° to 120°, with a mean of 66.08° on the right side and from 40° to 130° with a mean of 69.92° on the left side. No significant differences were identified between the two sides with respect to the relationship between the nerve and the inguinal ligament (Chi-square test, p=0.83); DAL (t test, p=0.37) or IA (t test, p=0.15). A single nerve was found in 70.83% of the dissections. The nerve was found inside the triangle in 95% of the dissections. CONCLUSIONS Despite the symmetry found between the right and left sides, the values of the main anatomic parameters involved in the localization of the LCN presented a great degree of variability. Even so, dissection using the proposed anatomical triangle allows for the localization of the LCN in almost all cases.

Abstract
PURPOSE Evaluate correlations between volume change for iliac crest bone grafts in maxillary reconstruction (graft volume change [GVC]) and bone mineral density (BMD), bone volume fraction (BVF), hematologic bone metabolic factors (I), and identify indicators of implant failure (II). MATERIAL AND METHODS Forty-six consecutive patients had their edentulous atrophic maxilla reconstructed with free autogenous bone grafts from anterior iliac crest. Endosteal implants were placed 6 months after graft healing. Computer tomography was performed after 3 weeks and 6 months after grafting. Bone biopsies were taken from the internal table of donor site for calculation (BVF), and blood samples were collected. Implant stability was measured at placement with resonance frequency analysis and expressed as implant stability quotient (ISQ). Implant failure was registered. RESULTS GVC in onlay bone graft was 37%. The BVF in iliac crest biopsies was 32%. Serum-IGFBP3 differed with 79% of the samples over normal range. Fifteen patients had one or more implant failures prior to loading (early failures). Forty-two patients were followed for a minimum of 3 years after implant loading and, in addition, 6/42 patients had one or more implants removed during the follow-up (late failures). GVC correlated to decreased BMD of lumbar vertebrae L2-L4 (Kruskal-Wallis test, p=.017). No correlation was found between GVC and hematologic factors (Pearson correlation test) or between GVC and BVF (Kruskal-Wallis test). No correlation was found between ISQ and GVC (Pearson correlation test, p=.865). The association between implant failures and the described factors were evaluated, and no significant correlations were found (unconditional logistic regression). CONCLUSION Onlay bone grafts decrease 37% during initial healing period, which correlate to BMD of lumbar vertebrae L2-L4. No other evaluated parameters could explain GVC. The evaluated factors could not explain implant failure.

Abstract
PURPOSE The goal of this study was to compare perioperative outcomes for the anterior versus posterior approach to the iliac crest for alveolar bone grafting in patients with cleft lip and palate (CLP). MATERIALS AND METHODS A retrospective cohort study of patients with CLP who had an anterior or posterior iliac crest bone graft during a 10-year period was performed. Available medical records were reviewed and the outcome variables documented included the operation site for bone graft procurement (anterior or posterior), estimated blood loss, duration of operation, concurrent procedures, and length of hospital stay. The 2 groups were compared by t test, Fisher exact test, and multivariate regression to show differences. RESULTS There were 239 patients with CLP who had an iliac crest bone graft to the alveolar cleft; 133 had an anterior and 106 a posterior approach for bone graft procurement. The mean estimated blood loss was significantly less with the posterior approach (85 vs 177 mL; P < .0001). The mean operation duration with the posterior approach was longer (4.6 vs 3.5 hours; P < .0001). Most patients in this group (67%), however, had 2 or more additional procedures during the same anesthetic, whereas only 16% of patients in the anterior group had 2 or more additional procedures. The mean length of stay was significantly shorter for the posterior approach (1.7 vs 2.2 days; P < .0001). CONCLUSIONS These results suggest that patients having a bone graft from the posterior iliac crest have a smaller estimated blood loss and a shorter length of stay. In addition, this approach permits repair of the alveolar cleft and additional procedures, including augmentation of the median tubercle and correction of nasolabial distortions, which are often present in patients with CLP.

Abstract
OBJETIVO: avaliar as possíveis complicações associadas à retirada de enxerto da crista ilíaca anterior em cirurgia para artrodese cervical anterior, em especial a dor residual. MÉTODOS: foi realizado estudo retrospectivo com análise de prontuários e aplicação de questionário via telefone com 20 pacientes no período compreendido entre Agosto de 2008 e Novembro de 2009. Todos os pacientes foram submetidos à mesma técnica cirúrgica para extração do enxerto, sendo operados pela mesma equipe no Hospital de Clinicas da Unicamp (HC Unicamp). As variantes analisadas foram dor residual, taxa de infecção, lesão neurológica ou vascular e ocorrência de fratura da asa do ilíaco. Os dados foram colocados em uma tabela e as médias e porcentagens foram calculadas. RESULTADOS: dos 20 pacientes, 12 homens e 8 mulheres, com média de idade de 51,75 anos (29-74) e follow-up médio de 11,83 meses (2-29), não houve nenhuma lesão grave, como fratura, lesão arterial ou neurológica. Houve um caso de infecção superficial (5%) e 25% dos pacientes queixaram-se de desconforto leve e dificuldade para deambular não incapacitante. CONCLUSÃO: a retirada de enxerto da crista ilíaca anterior está associada a muitas complicações, sendo importante o conhecimento de outras opções de enxerto e exposição ao paciente das possíveis complicações. Por meio deste levantamento, não verificamos nenhuma complicação grave, e o percentual de pacientes com dor residual acompanha os achados na literatura, podendo ser diminuído com uma dissecção cuidadosa da crista ilíaca.

Abstract
The location of lateral femoral cutaneous nerve (LFCN) in relation to the anterior superior iliac spine (ASIS) and the iliac crest was investigated in 96 embalmed cadaveric specimens. Fifty-six nerves (58.3%) passed medial to the ASIS. Twenty-two nerves (22.9%) passed at the ASIS. Eighteen nerves (18.8%) passed lateral to the ASIS. The LFCN is usually located at 2.1 +/- 0.8 to 3.9 +/- 1.0 cm below the crest in the range of 2-5 cm lateral to the ASIS, respectively. When the anterior iliac crest bone graft harvesting is planned, the anatomical variation in this area should be concerned to reduce the risk of LFCN injury.

Abstract
Peripheral nerve blocks (PNBs) of the lower extremities are effective techniques for anesthesia and postoperative pain control. So far, these techniques have been used less frequently than PNBs of the upper limb. Nevertheless, growing awareness of complications of neuroaxial techniques, improved equipment and modern techniques for nerve localization have led to an increased use of PNBs of the lower limb. Anesthesiologists should be familiar with the anatomical basics and procedural details of these PNBs. They should also know the typical complications and side-effects and thoroughly inform patients about such potential problems. Continuous PNBs (perineural catheters) allow the benefits of PNBs to be prolonged into the postoperative period. Compared to continuous neuroaxial techniques continuous PNBs are equally effective for pain control but seem to be associated with fewer complications and side-effects.

Abstract
BACKGROUND Lesion of the lateral femoral cutaneous nerve (LFCN) represents the main complication during minimally invasive anterior approach dissection to the hip joint. The aim of this anatomical study was to describe the different presentation features of the LFCN at the thigh and particularly to determine the potential location of damage during minimally invasive anterior approach for total hip replacement. METHODS The LFCN was dissected bilaterally at the thigh under the inguinal ligament in 17 formalin-preserved cadavers. Branching patterns of the nerve were recorded and distances from the LFCN to the anterior superior iliac spine (ASIS) and the anterior margin of the tensor fascia lata (TFL) were measured to clarify skin incision positioning during minimally invasive anterior approach for total hip replacement. RESULTS The LFCN divided proximal to the inguinal ligament in 13 cases and distal to it in 21 cases. In the distal group the mean distance from the ASIS to the nerve division was 34.5 mm (10-72 mm). The gluteal branch crossed the anterior margin of the TFL 44.5 mm (24-92 mm) distally to the ASIS. In 18 cases the femoral branch did not cross the TFL and was located in the intermuscular space between TFL and sartorius. In the remaining 16 cases, this branch crossed the anterior margin of the TFL 46 mm (27-92 mm) distally to the ASIS. During minimally invasive anterior approach along the anterior border of the TFL, the LFCN was found to be potentially at risk between 27 and 92 mm below the ASIS. We used those informations to describe a map of "danger zones" for the LFCN or its two main branches. CONCLUSION According to this study, numerous anatomical variations of the LFCN at the thigh should be considered when performing anterior approach to the hip joint. Different mechanisms of injury during surgery should be considered especially during minimally invasive total hip replacement, such as section of the gluteal or the femoral branch where it crosses the anterior margin of the TFL or stretching of the femoral branch due to retractors positioned into the intermuscular space between sartorius and TFL. According to the map of "danger zones" reported, the author policy consists of positioning the skin incision as lateral and distal to the ASIS as possible.

A biomechanical comparison of scaphoid fixation with bone grafting using iliac bone or distal radius bone. J Hand Surg Am 2007; 32:1367-73.

Abstract
PURPOSE Although many scaphoid fractures may be treated by immobilization, complex scaphoid fractures generally require bone grafting with internal fixation. A preferred source of bone graft for scaphoid grafting is the iliac crest. Donor site morbidity from iliac crest harvest, however, is a known complication, and the comparable strength and osteogenic properties of bone harvested from other sites are unclear. To this end, we have conducted a cadaveric comparative investigation of the strength of scaphoid nonunions with bone graft and internal fixation using either iliac crest bone or distal radius bone. METHODS Ten paired, human, fresh-frozen cadaveric wrists were used to create a standard midwaist wedge osteotomy into which identically shaped distal radius or iliac crest bone wedges were internally fixed using headless compression screws. After bone density and computed tomography assessment of the bones, benchtop biomechanical testing was conducted to compare the strength of the scaphoids after iliac and distal radius grafting, at 2-mm displacement, and at failure. RESULTS Analysis of scaphoid length, width, height, weight, density, and screw placement revealed no statistical differences between both bone graft groups. Although not significant, scaphoid nonunions grafted with distal radius bone evidenced a reduced load (3.23 +/- 0.26 Nm) to 2-mm displacement compared with iliac crest bone (5.97 +/- 0.68 Nm). Similarly, though not significant, scaphoids grafted with distal radius bone showed a reduced load (4.18 +/- 0.30 Nm) to failure compared with iliac crest bone grafting (6.42 +/- 0.66 Nm). Although no significance was found between the 2 grafting methods, a trend toward greater strength in the iliac crest graft group was observed. CONCLUSIONS Given the comparable biomechanical strength shown between iliac and distal radius bone in this study and the simplified surgical technique of distal radius harvesting, the data justify use of distal radius bone as a viable alternative donor source in scaphoid fracture treatment.

Abstract
A protein loaded three-dimensional scaffold can be used for protein delivery and bone tissue regeneration. The main objective of this project was to develop recombinant human bone morphogenetic protein-2 (rhBMP-2) loaded poly(D,L-lactide-co-glycolide)/hydroxylapatite (PLGA/HAp) composite fibrous scaffolds through a promising fabrication technique, electrospinning. In vitro release of BMP-2 from these scaffolds, and the attachment ability and viability of marrow derived messenchymal stem cells (MSCs) in the presence of the scaffolds were investigated. The PLGA/HAp composite scaffolds developed in this study exhibit good morphology and it was observed that HAp nanoparticles were homogeneously dispersed inside PLGA matrix within the scaffold. The composite scaffolds allowed sustained (2-8 weeks) release of BMP-2 whose release rate was accelerated with increasing HAp content. It was also shown that BMP-2 protein successfully maintained its integrity and natural conformations after undergoing the process of electrospinning. Cell culture experiments showed that the encapsulation of HAp could enhance cell attachment to scaffolds and lower cytotoxicity.
