Loss of the extensor mechanism at the distal interphalangeal (DIP) joint leads to mallet finger also known as baseball finger or drop finger. This can be secondary to tendon substance disruption or to a bony avulsion. Soft tissue mallet finger is the result of a rupture of the extensor tendon in Zone 1, and a bony mallet finger is the result of an avulsion of the extensor tendon from the distal phalanx with a small fragment of bone attached to the avulsed tendon. Mallet finger leads to an imbalance in the distribution of the extensor force between the proximal interphalangeal (PIP) and DIP joints. If left untreated, mallet finger leads to a swan neck deformity from PIP joint hyper extension and DIP joint flexion. Most mallet finger injuries can be managed non-surgically, but occasionally surgery is recommended for either an acute or a chronic mallet finger or for salvage of failed prior treatment.
BackgroundFasciotomy for compartment syndrome is an emergent procedure that is usually done in the operating theater under general anesthesia. Delay in performing the procedure can lead to worse outcome. Various reasons can cause delay in performing the surgery. Bedside fasciotomy under local anesthesia can be done in these cases to avoid delay in compartment release.Materials and methodsThis was a retrospective study of 34 cases of acute compartment syndrome for which fasciotomy was done at the bedside under local anesthesia. The minimum follow-up period was 6 months.ResultsAll patients had immediate and marked improvement in pain. Thirty-three patients regained their normal muscle strength. Thirty-two patients regained normal range of motion of adjacent joints. One patient developed flexion contracture of the great toe. There was no deep infection, chronic osteomyelitis, or amputation. Superficial wound infection was noted in three patients; one patient had persistent foot drop.ConclusionBedside fasciotomy under local anesthesia is a feasible, safe, and effective choice for treating compartment syndrome in patients with delayed presentation or those with anticipated delay to undergo surgery in the operating theater under general or regional anesthesia. The results of this study are encouraging, as all wounds healed satisfactory and there were no cases of deep infections. The formal release of compartments in the operating room under general anesthesia continues to be the standard of care. This is the first description in the literature for bedside fasciotomy under local anesthesia with a relatively large number of patients.
We were able to identify the relationship of the circumflex scapular artery to the anatomic landmarks of the scapula and to define the "at risk area" for the ascending branch of the circumflex scapular artery and its anastomosis with the suprascapular artery. We believe our anatomical study may aid in the avoidance of vascular complications during internal fixation of scapular fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
