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 ...
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.
Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications. Common sites for intramuscular injections include the deltoid muscle of the upper arm and the gluteal muscle of the buttock. In infants, the vastus lateralis muscle of the thigh is commonly used. The injection ...
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 ...
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.
In a positive Trendelenburg's sign the pelvis sags toward the normal unsupported side (the swing leg). The opposite, when the pelvis is elevated on the swing side, is known as Duchenne limp. Bilateral loss of the small gluteal muscles results in a waddling gait .
Patients also frequently report persistent or intermittent pain or dysthesias in posterior hip, buttocks, or thigh. [4] Unlike discogenic sciatica (caused by the spine), patients with deep gluteal syndrome report exacerbation of symptoms with pressure in the buttocks, such as tenderness or pain on deep palpation, or pain on prolonged sitting.
It can also affect the thigh, buttock, hand, abdomen, and foot. [19] [14] The most common cause of acute compartment syndrome is a fractured bone, usually the tibia. [29] [30] Leg compartment syndrome occurs in 1% to 10% of tibial fractures [7]. It is strongly linked to tibial diaphysis fractures and other tibial injuries. [31]
