RESUMO
Chronic exertional compartment syndrome (CECS) of the lower extremities is a common clinical condition characterized by exercise-induced pain in the extremities, which is predominantly observed in people who take an active part in sports, such as athletes. It is mainly presented as post-exercise pain in the lower extremities, probably accompanied by numbness and limb weakness, etc., affecting the patients′ life and work. The symptoms of CECS in the lower limbs are usually present after physical activities of a certain intensity, making them difficult to be identified through routine outpatient physical examination, and likely to be misdiagnosed and underdiagnosed. Furthermore, the absence of universally accepted and unified treatment standards for CECS of the lower extremities complicates the decision-making process regarding the necessity of surgical intervention and choice of surgical approach in the clinical practice. For this purpose, recent developments in the diagnosis and treatment of CECS of the lower extremities were reviewed to provide reference for its standardized diagnosis and treatment.
RESUMO
The presence of tension blister often predicts severe soft tissue damage，which not only increases the risk of wound complications but also prolongs the surgical treatment time. However，the developed tension blister has been proposed as a potential decompressive approach for it may relieve the pressure of osteofascial compartment and improve the likelihood of relieving clinical symptoms，as well as avoid unnecessary surgery in cases of suspected osteofascial compartment syndrome. Recently，the osteofascial system has been increasingly recognized that associations were found between the tension blister and osteofascial self-release processing. Thus，the timing of blister occurrence and regression substantially influences physicians′ clinical decisions，making blister management as part of the treatment of fractures. In this review，the authors give an overview of the characteristics，mechanism，stress reduction effect，prevention，current treatment status and complications of the fracture-related tension blister，hoping to help orthopedic physicians understand and treat the tensile blister.
RESUMO
Osteofascial compartment syndrome (OFCS) is clinically common and is well known to orthopedic surgeons.Clinicians attach great importance to OFCS because of its severe clinical consequences,and decompression of fascial compartment is often performed in emergency treatment.This article reviews the literature on the threshold of fascial compartment decompression proposed by many scholars in the past and discusses the problems in the clinical diagnosis of acute compartment syndrome,especially the inconsistent pressure thresholds as the indication for emergency decompression surgery.By observing calf fractures patients with tension blister,we found that the pressure of fascia decreased sharply upon the appearance of blisters.Meanwhile,the swelling gradually subsided as well as the clinical manifestations of pain and parasthsia.In view of the uncertainty of various thresholds of fascial decompression and self-decompression,the concepts of myofascial self-release law and muscle-swelling syndrome were first proposed.The author believes that when intracompartmental pressure rises to a point,some unknown mechanisms of fascia can achieve self-decompression.Therefore,no compartment syndrome will take place.We also emphasize that the ' muscle-swelling syndrome'should be strictly distinguished from the soft tissue necrosis caused by crush syndrome and acute limb vascular injury,so as to provide more precise treatment.We believe that without external restrictions such as casts,splints and compression bandages,the muscle-swelling syndrome can achieve self decompression by releasing the pressure in the compartment through tension blisters,and there is no need for fasciotomy.
