	'''Syndesmotic screw''' is a type of [[orthopedic hardware]] used in the treatment of [[ankle injuries]], specifically those involving damage to the [[syndesmosis]].

	~~Syndesmotic screws are used in~~ the ~~treatment~~ of [[~~ankle fractures~~]] ~~that involve injury to the syndesmosis~~. ~~This can occur~~ in ~~isolation or in conjunction with fractures of~~ the ~~tibia and/or fibula. The goal~~ of ~~treatment with a syndesmotic screw is to restore the normal relationship between the tibia~~ and ~~fibula and to stabilize the ankle joint~~.		'''Tetrahydropapaveroline''' (THP) is a [[tetrahydroisoquinoline]] alkaloid that is derived from the metabolism of [[dopamine]]. It is a compound of interest in the study of [[neurotransmitter]] metabolism and has been implicated in various neurological processes.

	== ~~Procedure~~ ==		== Chemical Structure and Properties ==

	~~The procedure to insert~~ a ~~syndesmotic screw is typically performed under~~ [[~~general anesthesia~~]]~~. A small incision is made over the site~~ of ~~the syndesmosis and the screw is inserted through the fibula and into the tibia~~. ~~The screw~~ is ~~usually left in place for~~ a ~~period of time to allow the syndesmosis to heal~~, ~~after~~ which ~~it may be removed~~ in ~~a separate procedure~~.		Tetrahydropapaveroline is a member of the [[isoquinoline]] class of compounds, specifically a tetrahydroisoquinoline. Its chemical structure is characterized by a benzylisoquinoline skeleton, which is a common feature in many biologically active alkaloids. The molecular formula of THP is C16H17NO3.

	== ~~Complications~~ ==		== Biosynthesis ==

	~~As with any surgical procedure, there are potential complications associated with~~ the ~~use~~ of ~~syndesmotic screws~~. ~~These can include infection, damage to surrounding structures,~~ and ~~failure~~ of the ~~screw to properly stabilize the syndesmosis~~. ~~In some cases,~~ the ~~screw may need to be removed earlier than planned due to discomfort or other issues~~.		THP is synthesized in the body through the enzymatic conversion of [[dopamine]]. This process involves the action of [[monoamine oxidase]] and other enzymes that facilitate the formation of the tetrahydroisoquinoline structure. The biosynthesis of THP is part of the broader metabolic pathways involving catecholamines.

	== ~~See also~~ ==		== Biological Activity ==

	* [[~~Ankle fracture~~]]		Tetrahydropapaveroline has been studied for its potential role in the [[central nervous system]]. It is thought to interact with various neurotransmitter systems, including the [[dopaminergic system]]. THP may have neuroprotective effects, but it has also been implicated in neurotoxicity under certain conditions.

	{{~~stub~~}}		Research into THP has suggested that it may play a role in the pathophysiology of certain neurological disorders. Its ability to interact with dopamine receptors and other neurotransmitter systems makes it a compound of interest in the study of diseases such as [[Parkinson's disease]] and [[schizophrenia]].

'''Syndesmotic screw''' is a type of [[orthopedic hardware]] used in the treatment of [[ankle injuries]], specifically those involving damage to the [[syndesmosis]].
