Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
Superior gluteal nerve palsy causes injury to the superior gluteal nerve, which results in motor loss that manifests as a disabling gluteus medius limp. [5] The most common cause is an iatrogenic injury during hip surgery or an intramuscular injection. Lesions of the inferior gluteal nerve occur through iatrogenic injuries like surgery, trauma ...
The revision rate for injections is approximately 81% and a revision is likely to either be a repeat injection or a nerve decompression. [ 8 ] An emerging non-surgical treatment is radiofrequency ablation to destroy the lateral femoral cutaneous nerve.
In normal gait, the small gluteal muscles on the stance side can stabilize the pelvis in the coronal plane.Weakness or paralysis of these muscles caused by a damaged superior gluteal nerve can result in a weak abduction in the affected hip joint.
The vastus lateralis (/ ˈ v æ s t ə s ˌ l æ t ə ˈ r eɪ l ɪ s, ˈ r æ-/), also called the vastus externus, [1] is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh.
Piriformis syndrome is often left undiagnosed and mistaken with other pains due to similar symptoms with back pain, quadriceps pain, lower leg pain, and buttock pain. These symptoms include tenderness, tingling and numbness initiating in low back and buttock area and then radiating down to the thigh and to the leg. [ 72 ]
Injection fibrosis is a complication of intramuscular injection, occurring especially often in infants and children. Injections are often delivered to the quadriceps, triceps, and gluteal muscles, and thus the complication often manifests itself in those muscles. Patients are unable to fully flex the affected muscle. The condition is painless ...
