Chronic exertional compartment syndrome

Chronic exertional compartment syndrome is a relatively common, but often overlooked cause of leg pain in athletes. A careful history and physical examination is essential in the diagnosis of CECS. Affected individuals have recurrent, activity-related leg pain that recurs at a consistent duration or intensity and is only relieved by rest. Measurement of baseline and postexercise compartment pressures confirms the diagnosis and helps in the planning of treatment. Surgical treatment with fasciotomy of the involved compartments is successful in allowing patients to return to full activity levels. With surgical treatment, it is critical to address all affected compartments as well as releasing any fascial defects, both of which may cause recurrent symptoms if neglected. With appropriate diagnosis and treatment, excellent outcomes can be achieved and allow athletes to return to full, unrestricted activity levels.     

Chronic exertional compartment syndrome of the forearm

Chronic exertional compartment syndrome (CECS) is an overuse injury characterized by increased intracompartmental pressure during exercise. CECS has been described in the foot, thigh, and trunk, but 95% of cases occur in the lower leg. Interestingly, CECS may also affect the upper extremities and has been best described in the forearms. Unfortunately, due to the rarity of this condition, there is no consensus regarding its diagnosis and treatment. This review seeks to discuss the prevalence, etiology, diagnosis, and treatment of CECS of the forearms, which has been described in the literature.     

Chronic exertional compartment syndrome: muscle changes with isometric exercise

Chronic exertional compartment syndrome (CECS) is a well-documented cause of lower leg pain in active individuals. The pathophysiology is unclear, although it is generally believed to be associated with increased intramuscular pressure, but there is very little information about muscle function in relation to the onset of pain. PURPOSE: To investigate strength, fatigue, and recovery of the anterior tibial muscles in CECS patients and healthy subjects during an isometric exercise protocol. METHODS: Twenty patients and 22 control subjects (mean age 27.6 yr and 33.0 yr, respectively) performed a 20-min isometric exercise protocol consisting of intermittent maximal voluntary contractions (MVC). Central fatigue was evaluated by comparing changes in electrically stimulated (2 s at 50 Hz) and voluntary contraction force before and during the exercise, and then throughout 10 min of recovery. Muscle size was measured by ultrasonography. Pain and cardiovascular parameters were also examined. RESULTS: The absolute MVC forces were similar, but MVC:body mass of the patients was lower (P < 0.05) as was the ratio of MVC to muscle cross-sectional area (P < 0.01). The extent of central and peripheral fatigue was similar in the two groups. The patients reported significantly higher levels of pain during exercise (P < 0.05 at 4 min) and after the first minute of recovery (P < 0.001). An 8% increase in muscle size after exercise was observed for both groups. There were no differences in the cardiovascular responses of the two groups. CONCLUSIONS: CECS patients were somewhat weaker than normal but fatigued at a similar rate during isometric exercise. Patients reported higher pain than controls despite comparable changes in muscle size, suggesting that abnormally tight fascia are not the main cause of CECS symptoms.     

Two minimal incision fasciotomy for chronic exertional compartment syndrome of the lower leg

Chronic exertional compartment syndrome (CECS) of the leg is a pathological condition often related to overuse in subject who engage repetitive physical activities. Fascial release is the mainstay of surgical management. The purpose of this study was to evaluate the results obtained with a double incision decompressive fasciotomy. Eighteen consecutive athletes with a diagnosis of anterior and/or lateral CECS of the leg were operated on with a minimal double incision fascial release after a mean period of 4 months after onset of symptoms. In 11 cases (61%) CECS was bilateral. Surgery was performed without tourniquet and active mobilization was starting immediately. Sports activities were resumed gradually at a mean period of 25 days. The athletes were followed until 2 years. All resumed pre-injury level sports activity. Two patients (18%) of the 11 who underwent to bilateral fasciotomy referred a sensation of leg weakness for an average period of 3 months. The surgical technique presented in this paper seems to be a good mean to treat anterior and lateral leg CECS. The use of tourniquet is deconselled to obtain an accurate intraoperative haemostasis so reducing the risk of post-operative haematoma.     

Chronic exertional compartment syndrome after minor injury to the lower extremity

Since the 1950s, chronic exertional compartment syndrome of the lower leg has been thoroughly reported in the literature. The predisposing factors and pathophysiology of this condition, however, still are not fully understood. We present a case of a well-conditioned individual who developed a chronic exertional compartment syndrome of the left lower leg anterior compartment after a direct blow injury during a softball game. Trauma is not routinely implicated as a risk factor for chronic compartment syndrome, and the literature on this topic is scarce. We suggest that trauma, even low-velocity trauma, may precipitate a chronic exertional compartment syndrome. We review the literature regarding chronic exertional compartment syndromes preceded by trauma and offer explanations regarding the mechanisms by which a traumatic event may induce a chronic compartment syndrome.

Diagnosis,treatment options,and rehabilitation of chronic lower leg exertional compartment syndrome

Chronic exertional compartment syndrome of the lower leg is a well-described and documented cause of exercise-related pain in recreational, elite, and military athletes. Although this condition is common, the exact underlying mechanisms, those most at risk, long-term effects on muscular strength if unrecognized, and prevention strategies are relatively uncertain. Runners are most commonly affected and can be markedly impaired by the recurrent, often predictable pain that develops with exercise. An accurate history, high index of suspicion, and compartment pressure testing before and after symptomatic exercise confirms the diagnosis. Conservative therapy is minimally effective. Fasciotomy is the treatment of choice for athletes who are unwilling to modify their exercise or sport.     

Long-term outcome of fasciotomy with partial fasciectomy for chronic exertional compartment syndrome of the lower leg

BACKGROUND: Fasciotomy with partial fasciectomy for compartment syndrome has had good short-term results, but no long-term studies have been performed. HYPOTHESIS: Combining a partial fasciectomy with fasciotomy for compartment syndrome relieves pain and eliminates symptoms in the long term. STUDY DESIGN: Retrospective cohort study. METHODS: A self-administered questionnaire was given to 62 patients at a mean follow-up of 51 months after surgery. RESULTS: Of the 50 patients who underwent a single operation, 60% (30) reported an excellent or good outcome. Average pain and pain-on-running were significantly reduced, although some subjects still reported considerable levels of pain. Fifty-eight percent (36 of 62) were exercising at a lower level than before injury and, of these, 36% (13) cited the return of their compartment syndrome or the development of a different lower leg compartment syndrome as the reason for a reduction in exercise levels. Some subjects indicated early initial improvement followed by subsequent deterioration. CONCLUSION: This surgical technique reduces pain and allows the majority of patients to return to sports; however, patients should be counseled that they may not be able to return to their preinjury level of exercise or remain pain-free.     

Acute exertional compartment syndrome of the paraspinal musculature

BackgroundAcute exertional compartment syndrome of the paraspinal musculature is rarely reported. Only 24 cases have been recorded in the surgical literature since it was first described by Carr et al. in 1985. Supportive management is recommended in the literature but equipoise remains regarding whether to observe the patient only, or perform a lumbar fasciotomy.Materials and MethodsA 21 year old man presented to our hospital following progressively worsening lower back pain after a bout of deadlifting exercises. On presentation he had severe local pain, with tense and enlarged paraspinal muscles. An MRI demonstrated enlarged paraspinal musculature with increased T2 signal bilaterally.ResultsThe patient was treated with topical ice, bed rest, anti-inflammatory agents and hydration. The patient made a full recovery within days.ConclusionCompartment syndrome of the paraspinal muscles is a rare, but serious cause of acute back pain. Non operative treatment was successful in this case and suggests that fasciotomy is not necessary for all such patients.     

Revision surgery for exertional anterior compartment syndrome of the lower leg: technique, findings, and results

BACKGROUND: Recurrent symptoms or failure after fasciotomy for exertional anterior compartment syndrome is not uncommon. HYPOTHESIS: Symptoms from high compartment pressures can be secondary to involvement of the entire compartment or to localized constrictions from postsurgical fibrosis, as well as to entrapment of the superficial peroneal nerve. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Eighteen patients who underwent revision surgery for exertional anterior compartment syndrome were available for follow-up. All were athletes who had either a failure or a recurrence of symptoms at a mean of 23.5 months (range, 8-54 months) after the index fasciotomy. Pressure measurements using a slit catheter at rest, at 1 minute postexercise, and at 5 minutes postexercise were performed in 2 places within the compartment: in the area of the previous incision and in the proximal muscle belly of the tibialis anterior. Surgical technique consisted of a 2-incision approach with partial fasciectomy, exploration and decompression of the superficial peroneal nerve, and excision of all fibrotic tissue. An objective examination and a comprehensive subjective questionnaire previously described were performed at a mean follow-up of 42 months (range, 22-67 months). RESULTS: Sixty percent of patients had abnormal pressures only in a localized area, whereas 40% had high pressures throughout the compartment. Eight of 18 (44%) patients had symptoms, signs, and surgical findings of entrapment of the superficial peroneal nerve. At follow-up, 72% of patients had a satisfactory outcome (5 excellent, 8 good), and 28% had an unsatisfactory outcome for intense running sports (4 fair, 1 poor), although 3 patients with the fair results reported improvement with low-level activity. All 8 patients with documented peroneal nerve entrapment had a satisfactory outcome. CONCLUSION: Symptoms from high pressures can be secondary to involvement of the entire compartment or localized to a certain area from postsurgical fibrosis. Pressure measurements should be performed in at least 2 separate areas.
