Early diagnosis of tibial compartment syndrome: continuous pressure measurement or not?

Comparison of single and double incision leg fasciotomy in disaster settings-Experience from 2023 Türkiye earthquakes

INTRODUCTION

Although there are studies comparing methods for leg fasciotomy in compartment syndrome after fractures, choice of single or double fasciotomies in disasters was not investigated. The aim of this study was to compare the efficacy of single and double incision leg fasciotomy in the setting of disaster.

METHODS

Patients that have undergone fasciotomy after 2023 Kahramanmaraş earthquakes were retrospectively analyzed. The cases were separated into two groups as single incision and double incision according to the method of the first fasciotomy. The number of debridements after each fasciotomy, muscle group excisions, completion time of treatment, presence of amputation, the method of closure (primary closure or graft/flap) and positive results of wound cultures were analyzed and compared between two groups.

RESULTS

62 legs of 52 patients (22 females, 30 males, age 36.9 ± 11.2 years) with compartment syndrome that have undergone fasciotomy after 2023 Kahramanmaraş earthquakes were included in the study. Single-incision group included 27 legs and double incision group included 35 legs. Amputation was needed in 15 patients (%24.2), six in single incision group and nine in double incision group. (p = 0.75). Compartment excision (eight patients in single incision, nine patients in double incision groups, p = 0.81), number of debridements (median 4 in both groups, p = 0.55), wound closure time (median 17 days in single incision, 22 days in double incision groups, p = 0.52), graft or flap requirement (11 patients in single incision, 16 patients in double incision groups, p = 0.53), positive culture results (15 patients in single incision, 16 patients in double incision groups, p = 0.44) were not different statistically between two groups.

CONCLUSION

Single and double incision fasciotomy methods are equally effective and safe in treatment of compartment syndrome of the leg in disaster situations. To our knowledge, this is the first study comparing outcomes of single and double incision fasciotomy in disaster settings.

Role of lower extremity fasciectomy-fasciotomy in patients with persistent leg pain after stenting for chronic iliofemoral venous obstruction

Although clinical improvement after stenting for symptomatic iliofemoral venous obstruction has been demonstrated in multiple large studies, a small proportion of patients will experience persistent quality of life–impairing symptoms. Swelling in such a setting represents the concomitant presence of lymphedema and will respond to treatment directed at the lymphedema. In contrast, persistent pain likely arises from venous hypertension in the lower leg, leading to the development of chronic compartment syndrome. Evaluation of intracompartmental pressures in such patients can help confirm the diagnosis, and fasciectomy combined with fasciotomy will treat the issue. In the present series, we evaluated six patients (six limbs) who had undergone fasciectomy combined with fasciotomy and their outcomes.

Is It Compartment Syndrome? Two Case Reports and Literature Review

Recently, a unique entity of acute compartment syndrome (ACS) has been termed “silent” compartment syndrome. These patients develop ACS in the absence of classic pain and physical findings. We report two cases of posttraumatic silent ACS in two healthy competent adult patients presenting mainly with swollen tense compartments. In the first case, ACS was suspected in a 37-year-old male with left tibia and fibula shaft fractures after reassessment of the patient’s post-backslap application, which revealed painless swollen and tense compartments. In the second case, ACS suspicion was raised in a 27-year-old male with right comminuted tibial plateau fracture and a swollen but soft compartment that became tense over time. In both cases, intraoperative intracompartmental pressure testing during external fixator application confirmed the diagnosis, and both underwent emergent fasciotomy with good postoperative outcomes. The absence of pain does not exclude the diagnosis of ACS. Physicians must have a high index of suspicion when risk factors are present for ACS, and the diagnosis can be confirmed with intracompartmental pressure measurement. These case reports and literature review aim to enlighten the physicians about silent compartment syndrome.

Postoperative non-traumatic compartment syndrome (PNCS) in gynecologic surgery

PURPOSE

The postoperative non-traumatic compartment syndrome (PNCS) is a rare, but serious postoperative complication. Etiology, risk factors and clinical manifestation of PNCS are not well characterized since data in gynecologic and obstetric patients are limited.

METHODS

We performed a retrospective monocentric study of patients who underwent surgery for gynecologic or obstetrics conditions and identified five cases of PNCS, which were analyzed and compared to a control cohort in regard of incidence, clinical presentation, risk factors and clinical outcome.

RESULTS

Five cases of PNCS were identified among 19.432 patients treated between 2008 and 2019 with an incidence rate of 0.026%. The clinical examination was shown to be unreliable, lacking sensitivity in most clinical signs. Young age, obesity and long operation time were risk factors for the development of a PNCS. Fasciotomy for the treatment of a PNCS should not be delayed, since permanent function loss may occur early.

CONCLUSION

A low threshold of clinical suspicion might be prudent to identify PNCS following gynecologic surgery. In the presence of the described risk factors, any suspicion of a PNCS should be evaluated further and if necessary treated with fasciotomy urgently.

The compartment syndrome: is the intra-compartment pressure a reliable indicator for early diagnosis?

Compartment syndrome (CS) occurs when the pressure in an enclosed compartment increases due to tissue swelling or internal bleeding. As the intra-compartmental pressure (ICP) builds up, the blood flow to the tissue or the organ is compromised, resulting in ischemia, necrosis and damage to the nerves and other tissues. At the present there are no established diagnostic procedures, and clinical observations such as pain, paralysis and even compartment pressure monitoring are an unreliable determinant of the presence of the syndrome. Late diagnosis may result in fasciotomy, neurological dysfunctions, amputation and even death. Focusing on the frequently occurring CS of the lower leg, this work is aimed toward introducing a coherent, mechanically motivated analysis of the disease within the framework of poroelasticity. The fascia enclosing the compartment is treated as an inextensible and impermeable layer, and the tissue inside the compartment is represented as a fully saturated poroelastic solid. The model quantitatively predicts the highly non-uniform ICP buildup as a function of both time and location. These findings, which are in good agreement with clinical observations reported in the literature, shed light on the difficulties associated with the identification of the syndrome and may assist in improved diagnostic procedures.

Effectiveness of Serial Measurement of Differential Pressure in Closed Tibial Diaphyseal Fractures in Diagnosing Acute Compartment Syndrome using Whiteside's Technique

Acute Compartment Syndrome is a limb-threatening emergency and it occurs most commonly after fractures. The aim of our study is to find out the effectiveness of serial measurement of differential pressure in closed tibial diaphyseal fractures, in diagnosing acute compartment syndrome, using Whiteside’s technique. A total of 52 cases in the age group of 15 to 55 years admitted with closed fractures were studied for serial compartment pressure as well as serial differential pressure. Eight patients had persistent compartment pressure > 40mmHg, out of which only two patients had persistent differential pressure < 30mmHg and these two patients underwent fasciotomy. Thus, by measuring the compartment pressure serially and calculating differential pressure serially, acute compartment syndrome can be diagnosed or ruled out with higher precision, so that unnecessary fasciotomies can be avoided.

The pathophysiology, diagnosis and current management of acute compartment syndrome

Acute compartment syndrome (ACS) is a surgical emergency warranting prompt evaluation and treatment. It can occur with any elevation in interstitial pressure in a closed osseo-fascial compartment. Resultant ischaemic damage may be irreversible within six hours and can result in long-term morbidity and even death. The diagnosis is largely clinical with the classical description of ‘pain out of proportion to the injury’. Compartment pressure monitors can be a helpful adjunct where the diagnosis is in doubt. Initial treatment is with the removal of any constricting dressings or casts, avoiding hypotension and optimizing tissue perfusion by keeping the limb at heart level. If symptoms persist, definitive treatment is necessary with timely surgical decompression of all the involved compartments. This article reviews the pathophysiology, diagnosis and current management of ACS.

Comparison of intracompartmental pressures in a rabbit model of open and closed tibial fractures

We compared the intracompartmental pressures (ICPs) of open and closed tibial fractures with the same injury pattern in a rabbit model. In all, 20 six-month-old New Zealand White male rabbits were used. They were randomised into two equal groups of ten rabbits; an open fracture group (group 1) and a closed fracture group (group 2). Each anaesthetised rabbit was subjected to a standardised fracture of the proximal half of the right tibia using a custom-made device. In order to create a grade II open fracture in group 1, a 10 mm segment of fascia and periosteum was excised. The ICP in the anterior compartment was monitored at six-hourly intervals for 48 hours. Although there was a statistically significant difference in ICP values within each group (both p < 0.001), there was no significant difference between the groups for all measurements (all p ≥ 0.089). In addition, in both groups there was a statistically significant increase in ICP within the first 24 hours, whereas there was a statistically significant decrease within the second 24 hours (p < 0.001 for both groups). We conclude that open tibial fractures should be monitored for the development of acute compartment syndrome to the same extent as closed fractures.

What is the effect of compartment syndrome and fasciotomies on fracture healing in tibial fractures?

Acute compartment syndrome (ACS) in tibial diaphyseal fractures has been associated with such complications as infection, delayed fracture healing or non-union, sensory and motor deficits, deformities, and poor functional outcome. Essential condition of an uncomplicated recovery is early diagnosis with prompt decompression. A comprehensive review of the literature was performed to evaluate the impact of compartment syndrome and leg fasciotomies on the time to fracture union and the incidence of delayed union and non-union in tibial diaphyseal fractures. A total of 16 articles, which included 245 tibial fractures complicated with compartment syndrome were analysed. There were statistically significant differences in the time to healing, being longer by 4.90 weeks (p<0.001), and in the rates of delayed union or non-union (55% versus 17.8%) (p<0.001) when these fractures were compared to tibial fractures without compartment syndrome. Patients with ACS of the tibia undergoing leg fasciotomies should be informed about the increased risk of impaired fracture healing and longer time to union.

Prevalence of complications of open tibial shaft fractures stratified as per the Gustilo-Anderson classification

The aim of the present study was to comparatively analyse certain outcome measures of open tibial fractures, stratified per grade of open injury and method of treatment. For this purpose, a systematic review of the English literature from 1990 until 2010 was undertaken, comprising 32 eligible articles reporting on 3060 open tibial fractures. Outcome measures included rates of union progress (early union, delayed union, late union and non-union rates) and certain complication rates (deep infection, compartment syndrome and amputation rates). Statistical heterogeneity across component studies was detected with the use of Cochran chi-square and I(2) tests. In the absence of significant statistical heterogeneity a pooled estimate of effect size for each outcome/complication of interest was produced. All component studies were assigned on average a moderate quality score. Reamed tibial nails (RTNs) were associated with significantly higher odds of early union compared with unreamed tibial nails (UTNs) in IIIB open fractures (odds ratio: 12, 95% CI: 2.4-61). Comparing RTN and UTN modes of treatment, no significant differences were documented per grade of open fractures with respect to both delayed and late union rates. Surprisingly, nonunion rates in IIIB open fractures treated with either RTNs or UTNs were lower than IIIA or II open fractures, although the differences were not statistically significant. Significantly increased deep infection rates of IIIB open fractures compared with all other grades were documented for both modes of treatment (RTN, UTN). However, lower deep infection rates for IIIA open fractures treated with RTNs were recorded compared with grades I and II. Interestingly, grade II open tibial fractures, treated with UTN, presented significantly greater odds for developing compartment syndrome than when treated with RTNs. Our cumulative analysis, providing for each grade of open injury and each particular method of treatment a summarised estimate of effect size for the most important outcome measures of open tibial fractures, constitutes a useful tool of the practicing surgeon for optimal decision making when operative treatment of such fractures is contemplated.

Elderly tibial shaft fractures: Open fractures are not associated with increased mortality rates

OBJECTIVES

This study aims to assess whether elderly patients (>65 years) with open tibial shaft fractures (OFs) have increased mortality rates than those with closed fractures (CFs).

PATIENTS AND METHODS

Patients admitted during 2003-2005 with open/closed diaphyseal (AO 42) fractures of the tibia were eligible to participate.

EXCLUSION CRITERIA

Pathological and peri-prosthetic fractures.

RESULTS

A total of 54 patients (38 females) met the inclusion criteria. Twenty-six patients had sustained CF and 28 OF (Gustilo grade I (11), grade II (five), grade IIIa (two) and grade IIIb (10)). The OF group was statistically significantly different with higher injury severity score, secondary procedures and length of hospital stay (p<0.05). A higher rate of admission/length of stay to intensive care unit and complication rate was noted in the OF group. Mortality rate between the two groups was comparable (CF=2/26, OF=3/28).

CONCLUSIONS

Elderly patients with OFs of the tibial shaft have similar mortality rate to those with CFs.
