Procedure-oriented sectional anatomy of the foot.

This is the seventh and last in a series of studies related to procedure-oriented joint anatomy. This article reviews the anatomy of the foot and its relationship to procedures in the clinical setting with or without ultrasound guidance. Anatomically correct axial schematics allow injections to be envisioned relative to clinically important anatomy for common forefoot procedures. Cross-sectional schematics for the ankle were drawn as they appear in imaging projections. The levels and planes of cross section were selected to highlight important anatomic landmarks for injection. It is hoped that these schematics allow for safer and more accurate needle procedures in the foot area.

Procedure-oriented sectional anatomy of the ankle.

This is the sixth in a series of articles related to procedure-oriented joint anatomy. This article reviews the anatomy of the ankle and its relationship to procedures in the clinical setting with or without ultrasound guidance. Anatomically correct axial and oblique axial schematics allow injections to be envisioned relative to clinically important anatomy for common ankle procedures. Cross-sectional schematics for the ankle were drawn as they appear in imaging projections. The levels and planes of cross section were selected to highlight important anatomic landmarks for injection. It is hoped these schematics allow for safer and more accurate needle procedures in the ankle area.

Procedure-oriented sectional anatomy of the knee.

This is the fifth in a series of articles related to procedure-oriented joint anatomy. This article reviews the anatomy of the knee and its relationship to procedures in the clinical setting with or without ultrasound/electromyographic guidance. Anatomically correct axial schematics allow injections to be envisioned relative to clinically important anatomy for common knee procedures. Cross-sectional schematics for the knee were drawn as they appear in imaging projections. The levels and planes of cross section were selected to highlight important anatomic landmarks for injection. It is hoped that these schematics allow for safer and more accurate needle procedures in the knee area.

Procedure-oriented sectional anatomy of the wrist and hand.

This is the third in a series of papers related to procedure-oriented joint anatomy. This article reviews the anatomy of the wrist and hand and its relationship to procedures in the clinical setting with or without ultrasound/electromyography (EMG) guidance. Anatomically correct axial and coronal schematics allow injections to be envisioned relative to clinically important anatomy for common wrist and finger procedures. Cross-sectional schematics for the wrist and hand were drawn as they appear in imaging projections. The levels and planes of cross section were selected to highlight important anatomic landmarks for injection. It is hoped that these schematics allow for safer and more accurate needle procedures in the wrist and hand area.

Procedure-oriented sectional anatomy of the elbow.

This is the second in a series of papers related to procedure-oriented joint anatomy. This article will review the anatomy of the elbow and its relationship to procedures in the clinical setting. Needle procedures of the elbow joint include medial and lateral epicondyle injections, olecranon bursa injection, elbow joint aspiration, phlebotomies in the antecubital fossa, and intramuscular injections such as trigger point and botulinum toxin injections. Complications related to these procedures include infection, skin atrophy, injuries to peripheral nerves, tendon rupture associated with the use of corticosteroids, iatrogenic vascular injuries, and chronic local pain. This article provides anatomically accurate schematics of the elbow anatomy relevant to needle procedures. Cross-sectional anatomical schematics of the elbow were drawn as they appear on axial and coronal projections. Superficial and deep landmarks are highlighted as well as sources of potential complications. These schematics allow for safer and more accurate needle procedures in the elbow area, for both nonguided and musculoskeletal ultrasound-guided techniques.

Sectional neuroanatomy of the pelvic floor.

This is the sixth in a series of articles on the spine. The first 5 reviewed the sectional anatomy of the cervical, thoracic, and lumbosacral spines. This paper will review both the male and female pelves. Procedures performed in the pelvis include electromyography of the anal sphincter, pudendal and sacral nerve stimulator implants, and botulinum toxin type A injections into the prostate, the bladder, the urethra, and the anus. Complications from these procedures are rare. Electromyography in this region is particularly uncomfortable. Botulinum toxin type A denervation may result in local effects such as incontinence or urinary retention or rarely remote effects such as limb weakness. Neurostimulators may get infected or may fail. This article provides anatomically accurate schematics of innervations of the pelvis that can be used to interpret magnetic resonance images of muscles and nerves in the pelvic floor region. Cross-sectional schematics of the male and female pelves were drawn as they appear on imaging projections. The relevant nerves were color coded. The muscles and the skin surfaces were labeled and assigned the color of the appropriate nerves. An organized comprehensive map of the motor innervation of both the male and female pelves allows the physician to increase the accuracy and efficacy of interventional procedures. This anatomic map could also assist the electromyographer in correlating the clinical and electrophysiologic findings on magnetic resonance images.
