Lumbar plexus is one of the two nerve plexuses which supply the lower limb. It is formed in the posterior abdominal wall within the psoas major muscle. The branches of the plexus exit via the medial and lateral borders as well as its ventral surface. It is a complex plexus which gives a branch to complete the formation of lumbo sacral plexus. The branches mainly supply the groin, anterior and medial compartments of thigh. They also supply the hip and knee joints. The cutaneous innervation by the branches of lumbar plexus is limited to the anterior, lateral and medial parts of the thigh, medial side of the leg and foot and also the lower part of anterior abdominal wall and perineum. Regional anaesthesia is a highly skilled and precise technique used widely in the patients to reduce the drug usage and decrease the intra and post operative complications. Lumbar plexus block can be used in surgeries related to hip joint and anterior part of thigh and groin. To execute the procedure successfully, sound knowledge in anatomy of lumbar plexus is required.

Abstract Background Ilioinguinal, iliohypogastric, and genitofemoral nerves are together known as “border nerves” of the lumbar plexus. Aim of this study was to find out the variations in formation and branching pattern of these nerves and correlate with their clinical relevance. Materials and Methods For this study 30 formaldehyde preserved cadavers were used, and the nerves were studied on both the sides, thus making the sample size of 60. Results Iliohypogastric nerve was absent in 6.6% and double in 1.6%. It was prefixed with a twig from T12 in 6.6% and had origin from both L1 and L2 in 1.6%. The ilioinguinal nerve was absent in 3.3% and double in 3.3%. The genitofemoral nerve exhibited a large number of variations. It was absent in 1.6%. Early division of the nerve prior to emergence from the psoas major muscle was noticed in 13.3%, and early division soon after emergence from the muscle was noted in 3.3%. In one cadaver, on one side, genital branch was absent, and it continued as femoral branch only. In another cadaver, the nerve continued as genital branch only. In two other cases, genital and femoral branches were seen to arise separately from the lumbar plexus. The nerve had its origin from L1 and L2 in 25%, L2 and L3 in 25%, L1 in 3.3%, L2 in 46.66%, and L3 in 1.6% of the cases. Conclusion Knowledge of these variations would be of immense help during surgical approach and giving nerve block for anesthesia and postoperative analgesia in this region.

Lesions of lumbar plexus are uncommon and descriptions of surgical access are derived from vertebral spine approaches. METHOD: The extraperitoneal anterolateral approach to the lumbar plexus was performed in six adult fresh cadavers. The difficulties on dissection were related. RESULTS: An exposure of all distal elements of lumbar plexus was possible, but a cranial extension of the incision was needed to reach the iliohypogastric nerve in all cases. Ligation of vessels derived from common iliac artery was necessary for genitofemoral and obturator nerves exposure in two cases. The most proximal part of the lumbar roots could be identified only after dissection and clipping of most lumbar vessels. CONCLUSION: The extraperitoneal anterolateral approach allows appropriate exposure of terminal nerves of lumbar plexus laterallly to psoas major muscle. Cranial extension of the cutaneous incision may be necessary for exposure of iliohypogastric nerve. Roots exposure increases the risk of vascular damage.

Abstract Background Heterotopic pregnancy occurred after frozen embryo transfer with two D3 embryos, and the case had a history of bilateral salpingectomy due to salpingocyesis. An ectopic heterotopic pregnancy was implanted in the left psoas major muscle, which has not been previously reported. Case presentation A 33-year-old woman presented with left back pain after curettage due to foetal arrest in the uterus without vaginal bleeding and spotting, and painkillers relieved the pain initially. When the painkillers ceased to work, the patient returned to the hospital. The β-human chorionic gonadotropin (β-hCG) level remained increased compared with the time of curettage, and a diagnosis of retroperitoneal abdominal pregnancy was suggested by ultrasonography and computerized tomography (CT) with the gestational sac implanted in the left psoas major muscle at the left hilum level. Laparotomy was performed to remove the ectopic pregnancy. During the operation, we carefully separated the adipose tissue between the space of the left kidney door and left psoas major muscle, peeled away the gestational sac that was approximately 50 mm × 40 mm with a 25-mm-long foetal bud, and gave a local injection of 10 mg of methotrexate in the psoas major muscle. Fifty days later, β-hCG decreased to normal levels. Conclusion It is necessary to pay more attention to the main complaints to exclude rare types of ectopic pregnancies of the pelvis and abdomen after embryo transfer.
