Anatomy of The Lumbar Back Muscles-Internal Oblique

The internal oblique is the largest muscle of the abdominal wall . The internal oblique forms the middle layer of the abdominal wall between the TrA and the external oblique. It originates from the “lateral two-thirds of the inguinal ligament, anterior two-thirds of the iliac crest, and the lateral raphe of the thoracolumbar fascia in […]

Passive abduction

POSitioning.

The subject lies in the supine position,near the border of the couch, with the lower leg pendent. The examiner stands level with the subject’s hip. One hand grasps the distal thigh from the medial side. The other hand is placed on the opposite anterior superior iliac spine in order to stabilize the pelvis.

Procedure. […]

Hip and pelvis

Injuries to the pelvis, hip, and thigh involve the largest soft tissue structures in the body. Such injuries can be extremely disabling and often require a substantial amount of time for rehabilitation. The whole lower extremity must be considered, along with gait analysis and posture. When rehabilitating the hip and pelvis,proprioceptive and balance activities should […]

Sacroiliac Dysfunction (Inflammation of the Sacroiliac Joint)

Inflammation of the sacroiliac joints (the joint joining the pelvis and the spine) is not uncommon as an isolated condition among athletes who pursue winter sports. It can also be part of generalized disease, such as Bechterew’s disease. In sports, sudden violent contractions of the hamstrings or abdominal muscles with severe direct load to the […]

Giant Cell Tumor

Basics Description A benign but often locally aggressive neoplasm, characterized by large numbers of uniformly distributed, osteoclastlike giant cells and a background population of plump, epithelioid-to-spindle mononuclear cells. The vast majority of these tumors are located near the articular end of a tubular bone; ~50% occur in the knee. Other frequently involved sites: Distal […]

Ewing Sarcoma

Basics Description Ewing sarcoma is a malignant bone tumor of the long bones, pelvis, and spine usually seen in childhood. Bone pain is the most common finding. Fever and an elevated white blood cell count and ESR sometimes are found. Nerve root irritation may be noted in patients with spinal lesions. It most commonly […]

Eosinophilic Granuloma

Basics Description EOG is the bony, and most common, manifestation of a group of nonneoplastic disorders known as LCH. 3 basic scenarios occur: Solitary site bone disease Multiple bone lesions without visceral disease Multiple bone lesions and visceral disease EOG commonly affects the skull, ribs, pelvis, spine, diaphysis of long bones, and mandible, but […]

Computed Tomography

Basics Description CT is a noninvasive diagnostic technique that uses a rotational radiographic source to generate cross-sectional images. CT is particularly advantageous for musculoskeletal imaging when used with multiplanar, volume-rendered reconstruction techniques. Etiology Chronology of development : 1972: Introduction 1974-1976: 1st clinical scanners installed 1980: Became widely available 1985-1986: Introduction of modern applications, such […]
