Surgical treatment and late results of foot compartment syndrome]

From 1982 to 1988 a total of 29 patients with compartment syndrome of the foot were treated by fasciotomy. The most common causes were fracture dislocations of the Lisfranc (n = 14) and Chopart joints (n = 4). Since these injuries lead to a severe damage to soft tissue structures--joint capsules, ligaments, fasciae--the muscular compartments often communicate and decompression can be achieved by a longitudinal dorsal incision of the skin and fasciotomy of the fascia dorsalis pedis and the retinacula extensorum superior and inferior. Subsequent measurement of intracompartmental pressure dictates whether blunt dissection of the interosseous muscles and separate fasciotomy of the medial, lateral and plantar compartments have to be performed. Follow-up was possible in 18 patients: half had good results, while 9 patients had limited motion of their toes and/or paresthesia. It is impossible to know whether these negative findings are caused by the compartment syndrome itself or by the severe soft tissue damage resulting from the initial trauma.     

Compartment syndrome in ipsilateral humerus and forearm fractures in children

Ipsilateral fractures of the humerus and forearm are uncommon injuries in children. The incidence of compartment syndrome in association with these fractures is controversial. The authors reviewed 978 consecutive children admitted to the hospital with upper extremity long bone fractures during a 13-year period. Forty-three children with ipsilateral fractures of the humerus and forearm were identified. Of 33 children with a supracondylar humerus fracture and ipsilateral forearm fracture, three children (7%) had compartment syndrome develop and required forearm fasciotomies. All three cases of compartment syndrome occurred among nine children with ipsilateral displaced extension supracondylar humerus and displaced forearm fractures; the incidence of compartment syndrome was 33% in this group. These findings suggest that children who sustain a displaced extension supracondylar humerus fracture and displaced forearm fracture are at significant risk for compartment syndrome. These children should be monitored closely during the perioperative period for signs and symptoms of increasing intracompartmental pressures in the forearm.     

Acute compartment syndrome

Compartment syndrome is an orthopaedic emergency. It is defined as an increase in pressure within an osseofascial compartment, which results in hypoxia and necrosis of the structures within the compartment. It is commonly associated with high energy injuries, particularly tibial fractures. Diagnosis is largely based on clinical assessment, with pain as the most important and reliable feature. Other features such as nerve compromise or pulselessness are late signs. Urgent treatment should be based on guidelines written by the British Orthopaedic Association. Fasciotomy of the affected limb is required within an hour of the diagnosis being made to reduce morbidity associated with the condition. In the leg there are four compartments, which can be decompressed through two skin incisions. The wounds cannot be closed primarily, and multiple theatre attendances may be required. If a fracture is present as well as compartment syndrome, this will need to be stabilized at the same time. A variety of options for managing the wounds are available, with no single ideal method.     

Verletzungen des Fußes beim polytraumatisierten Patienten

Foot injuries in polytraumatized patients are not critical for survival but for the later quality of life. Closed fractures or dislocations of the foot are frequently overlooked or misinterpreted in association with polytrauma, which leads to severe functional impairment in those patients who survive. Repeated clinical examinations and early radiographic examinations are essential in the unconscious patient after resuscitation. Emergent indications for surgery even in the presence of multiple injuries are open injuries, incarcerated soft tissues, manifest compartment syndrome of the foot, and neurovascular injury. The decision on limb salvage or amputation has to be individualized with respect to the patient's overall condition and the severity of local trauma to the foot. The "life before limb" principle has to be respected. Emergent reduction of fracture dislocations of the talus, calcaneus, Chopart's and Lisfranc's joints via direct approaches and temporary transfixation with K-wires should be attempted in a first step whenever possible. Additional external fixation facilitates wound care and prevents soft tissue contractions until definite internal fixation becomes feasible. Early soft tissue coverage is always sought in order to avoid infection.     

Management of compartment syndromes of the foot.

Twelve patients with isolated extremity injuries had 14 compartment syndromes of the feet. An interstitial pressure of more than 30 mm of mercury in either the central or interosseous compartment was considered pathologic and was treated by fasciotomy, performed dorsally in nine feet and medially in five. Open reduction of fractures amenable to internal fixation (eight tarsometatarsal, three calcaneus, and one metatarsal) was performed after completion of the fasciotomies. The fasciotomy wounds were covered by primary split-thickness skin excision (three), delayed split-thickness skin grafting (eight), and delayed primary wound closure (three). Patients were evaluated at a mean of 22 months (range, 17-36 months) after injury, and the examination was directed specifically toward symptoms and signs of myoneural ischemia. Absolute compartment pressure measurements are more accurate than clinical findings in the diagnosis of a compartment syndrome of the foot. Fasciotomy may be performed medially or dorsally, depending on the configuration of the pattern of fracture or dislocation. To ensure satisfactory results, all compartments should be decompressed, and the pressures remeasured after the completion of fasciotomy.     

Gunshot injuries to the liver: the role of selective nonoperative management

BACKGROUND: Selective nonoperative management of blunt liver injuries has become standard practice in most trauma centers. We evaluated the role of selective nonoperative management of gunshot wounds to the liver. STUDY DESIGN: This was a retrospective review of gunshot wounds to the liver treated in a level I trauma center. Patients with peritoneal signs or hemodynamic instability were operated on without delay. Patients with a soft, nontender abdomen and no signs of heavy bleeding were selected for nonoperative management. Liver injury was diagnosed by CT scan. If peritonitis or signs of substantial internal bleeding developed, an operation was performed; otherwise the patient was discharged within a few days of admission. Analysis was restricted to the group of patients with isolated liver injuries. RESULTS: During a 42-month period, 928 patients were admitted with abdominal gunshot injuries, 152 of whom (16%) had a liver injury. In 52 patients (34% of all liver injuries), the liver was the only injured intraabdominal organ (4 patients had associated kidney or splenic injuries that did not require surgical repair). Thirty-six of the patients (69%) with isolated liver injuries had an emergent operation because of signs of peritonitis or hemodynamic instability. The remaining 16 patients (31%) were selected for nonoperative management (3 patients had associated right kidney injury). Five patients in the observed group required delayed operation because of development of signs of peritonitis (4 patients) or abdominal compartment syndrome (1 patient). The remaining 11 patients (7% of all liver injuries or 21% of isolated liver injuries) were managed successfully without operation. One patient with delayed operation developed multiple complications from abdominal compartment syndrome, and 1 patient in the nonoperative group had a biloma, which was treated with percutaneous drainage. CONCLUSIONS: Selected patients with isolated grades I and II gunshot wounds to the liver can be managed nonoperatively.     

Acute intra-abdominal hypertension and "abdominal compartment syndrome"

The acute intra-abdominal hypertension causes profound physiologic abnormalities, both within and outside the abdomen. Just as in compartment syndrome in the extremities, gut mucosal ischemia begins long before clinical signs are evident, explaining the name of "abdominal compartment syndrome" given to the acute, markedly increased intra-abdominal pressure. The abdominal compartment syndrome was initially described in patients with severe abdominal injuries and massive transfusions and crystalloid infusions, caused by the closure of fascia or skin under tension, the use of bulky abdominal packs to control diffuse bleeding, the massive bowel distension and edema, and the continued bleeding into the abdominal cavity. Intra-abdominal pressure can be monitored by measuring the urinary bladder pressure with a manometer, connected to the transurethral Foley catheter, with the symphysis pubis as the zero point. A persistent elevation of the intra-abdominal pressure beyond 20-25 cmH2O, with significant respiratory, hemodynamic and renal dysfunction is an indication for abdominal decompression, before the manifestations of abdominal compartment syndrome became clinically evident. The mortality in patients with abdominal compartment syndrome is over 40%, even when adequately treated.     

Injuries of the hand and forearm in young children caused by steam roller presses in laundries.

Fourteen children (median age 43 months, range 14-82 months; 7 girls and 7 boys) were treated for mangle injuries (one hot steam, and 13 cold roller presses) to the hand and forearm between 1996-2002 at the Department of Hand Surgery, Malm?, Sweden. All children had unilateral skin damage with avulsion or necrosis of skin in nine. Seven of the 14 had signs of compartment and carpal tunnel syndromes and three had fractures (phalanges or hamate bone). Initial treatment included fasciotomy, decompression, and skin revision with split skin grafts and later further skin cover, including one pedicled ulnar flap. IN eight the injuries healed uneventfully, while six had slight consequences (such as minor extension deficit of fingers or slight contracture of the scar). Ten of the 14 children came from immigrant families. Mangle injuries can be prevented through better supervision of children by parents when the mangle is being used, and dissemination of information of the potential hazards in relevant languages in residential areas with large immigrant populations.     

Mechanical impedance: a new noninvasive method for measuring tissue pressure in anterior compartment syndrome. II. Results of clinical measurements in patients with tibial trauma

In acute compartmental syndrome, it is difficult to decide on the basis of clinical criteria alone whether fasciotomy is indicated or not. Reliable and objective parameters are required before a treatment schedule can be devised. We tested mechanical impedance as a parameter for the pressure inside the tissue. The technique and associated apparatus for measuring mechanical impedance of the skin overlying the anterolateral compartment of the lower leg are described in detail. We performed the non-invasive measurement in 25 patients with leg injuries. There were 2 patients with acute compartmental syndrome and 5 with imminent compartmental syndrome. In normal legs, the mechanical impedance was between 2 and 6.5 kg/s, with an average of 3.83 kg/s. After the impedance is increased to 10 kg/s or higher, there is acute or imminent compartmental syndrome. Once the compartment has been decompressed by unilateral parafibular fasciotomy, the mechanical impedance decreases to normal values. Clinically relevant results were obtained by this method and they correlated well with the other clinical findings.     

Clinical spectrum of acute compartment syndrome of the thigh and its relation to associated injuries

The reason for the described clinical variability of acute compartment syndrome of the thigh, with high morbidity and mortality in some patients and an uncomplicated clinical course in others, is not known. To better define the clinical spectrum and factors determining the clinical course of this rare clinical entity, we did a retrospective multicenter study of 28 patients with 29 thigh compartment syndromes. The leading cause of acute thigh compartment syndrome was blunt trauma from motor vehicle accidents (46%) or contusion (39%). Pain with passive motion was present in all patients who were conscious, followed by paresthesia (60%), and paralysis (42%). The anterior compartment was involved most frequently with mean compartment pressure of 58 +/- 3 mm Hg. Myonecrosis, sepsis, and need for skin grafting were observed more frequently in patients with ipsilateral femur fracture. Only 7% of patients with isolated thigh compartment syndromes had short-term complications compared with 57% of patients with ipsilateral femur fractures. The incidence of complications correlated with the time to fasciotomy. Mortality was limited to patients with high injury severity scores. The clinical spectrum of thigh compartment syndrome is comparable with that of other compartment syndromes and its clinical course is determined by its associated injuries.     

Compartment syndrome after low-velocity gunshot wounds to the forearm

Between 1980 and 1988, 127 patients with 131 low-velocity gunshot wounds to the forearm were treated. In 71 extremities there was no bony injury; 60 extremities sustained fractures. The diagnosis of a compartment syndrome was based on tissue pressure measurements and/or clinical examination. A univariate analysis followed by a multivariate stepwise logistic regression was used to evaluate potential risk factors including fracture location, displacement, comminution, and the quantity of radiographically determined metallic foreign bodies in the wound. A compartment syndrome was diagnosed in 13 of the extremities (10%). Fracture location was the only significant risk factor for the development of a compartment syndrome. Low-velocity gunshot injuries to the forearm are at definite risk for the occurrence of a compartment syndrome. A high index of suspicion is necessary to prevent untoward sequelae. Patients with this injury, especially those with a proximal one-third fracture who constitute an extremely high-risk group, should be monitored closely.     

Delaying treatment of supracondylar fractures in children: has the pendulum swung too far?

The aim of this retrospective multicentre study was to report the continued occurrence of compartment syndrome secondary to paediatric supracondylar humeral fractures in the period 1995 to 2005. The inclusion criteria were children with a closed, low-energy supracondylar fracture with no associated fractures or vascular compromise, who subsequently developed compartment syndrome. There were 11 patients (seven girls and four boys) identified from eight hospitals in three countries. Ten patients with severe elbow swelling documented at presentation had a mean delay before surgery of 22 hours (6 to 64). One patient without severe swelling documented at presentation suffered arterial entrapment following reduction, with a subsequent compartment syndrome requiring fasciotomy 25 hours after the index procedure. This series is noteworthy, as all patients had low-energy injuries and presented with an intact radial pulse. Significant swelling at presentation and delay in fracture reduction may be important warning signs for the development of a compartment syndrome in children with supracondylar fractures of the humerus.     

Pediatric floating elbow.

SUMMARY: A retrospective review of 16 patients with floating elbow injuries over a 9-year period at a tertiary care children's hospital confirms that these injuries are associated with substantial swelling and the potential to develop compartment syndrome, particularly when circumferential cast immobilization is used. Among 10 patients in whom the forearm was treated with closed reduction and plaster immobilization, a compartment syndrome developed in 2, and 4 patients had incipient compartment syndrome that responded to splitting of the cast; 3 of these subsequently required remanipulation of the distal radius. One patient with compartment syndrome had Volkmann ischemic contracture. Six patients underwent stabilization of both the distal humeral and forearm fractures with percutaneously inserted Kirschner wires, thereby allowing postreduction immobilization in a split cast. None of these patients had problems with excessive swelling or compartment syndrome. Percutaneous Kirschner wire fixation of both the humeral and forearm fractures in pediatric floating elbow injuries allows noncircumferential immobilization, thereby reducing the risk of compartment syndrome.     

Acute compartment syndrome in children: contemporary diagnosis, treatment, and outcome

Compartment syndrome can be difficult to diagnose in a child, with delays in diagnosis leading to disastrous outcomes. Thirty-six cases of compartment syndrome in 33 pediatric patients were treated at the authors' institution from January 1, 1992, to December 31, 1997. There were 27 boys and 6 girls, with nearly equal upper and lower extremity involvement. Approximately 75% of these patients developed compartment syndrome in the setting of fracture. Pain, pallor, paresthesia, paralysis, and pulselessness were relatively unreliable signs and symptoms of compartment syndrome in these children. An increasing analgesia requirement in combination with other clinical signs, however, was a more sensitive indicator of compartment syndrome: all 10 patients with access to patient-controlled or nurse-administered analgesia during their initial evaluation demonstrated an increasing requirement for pain medication. With early diagnosis and expeditious treatment, >90% of the patients studied achieved full restoration of function.     

Dynamic wound closure for decompressive leg fasciotomy wounds

Decompressive fasciotomy for preservation of lower extremity function and salvage is an essential technique in trauma. The wounds that result from the standard two incision four-compartment leg fasciotomy are often accompanied by a wide soft tissue opening that in the face of true compartment syndrome are often impossible to close in a delayed primary fashion. We describe a technique using a device that allows for dissipation of the workload across the wound margin allowing for successful delayed primary closure. Consecutive patients who presented to the 28th Combat Support Hospital in Baghdad, Iraq with a diagnosis of compartment syndrome of the leg, impending compartment syndrome of the leg, or compartment syndrome of the leg recently treated with fasciotomies were followed. All patients underwent placement of the Canica dynamic wound closure device (Canica, Almonte, ON, Canada). Eleven consecutive patients treated at a combat support hospital in support of Operation Iraqi Freedom underwent four-compartment fasciotomies for penetrating injuries. There were five patients that underwent a vascular repair [three superficial femoral artery (SFA) injuries and two below knee popliteal artery injuries] and six patients that had orthopedic injuries (three comminuted tibial fractures, two fibula fractures, and one closed pilon fracture). Patients returned to the operating room within 24 hours for washout and wound inspection. Mean initial wound size was 8.1 cm; mean postplacement size was 2.7 cm; average time to closure was 2.6 days. All patients were able to undergo primary wound closure of the medial incision and placement of the Canica device over the lateral incision. Ten of the 11 patients (91%) could be closed in delayed primary fashion after application of the device. In our series of patients with penetrating wartime injuries and compartment syndrome of the leg we have found the use of this dynamic wound closure device to be extremely successful and expedient.     

Zur Behandlung der geschlossenen Verrenkung des Kniegelenkes

Nineteen knee dislocations in 18 patients (one bilateral) occurred over a period of twelve years. The age range was 17 to 70 years with an average age of 33 years. There was no injury of the popliteal artery and five peroneal nerve injuries in the group. One compartment syndrome occurred after reduction. The follow-up study including examination showed good and satisfactory results for early surgical repair. After delayed surgical repair there were more signs of instability, pain and restrictive range of flexion movement. Early operative repair followed by cast bracing for six weeks and an intensive mobilisation therapy after cast bracing are the method of choice. An immobilisation period of three to four weeks is possible.     

Results of treatment of compartment syndrome of the upper arm

Only a small number of cases of compartment syndrome in the upper arm has been reported in the literature. The authors have reviewed 14 patients with 14 cases of compartment syndrome treated at their institution from 1980 to 1988. In the majority of cases in this series, compartment syndrome was caused by blunt, high-energy trauma. There were 9 patients with multiple trauma, 7 of whom were motor cyclists, and fracture of the upper arm was present in most of these. In 5 patients scapulothoracic dissociation with disruption of the neurovascular bundle of the upper extremity concerned was present. In this series, 2 patients died of their injuries and three arms had to be amputated. At final follow-up after an average of 45 months (range 11-91 months) the functional result was dependent mainly on the severity of the associated injuries. Patients with isolated compartment syndrome had full recovery of upper limb function.     

Management of soft-tissue injuries in distal radius fractures

Distal radius fractures account for approximately 15% of all fractures in adults, and are the most common fractures seen in the emergency department. Soft-tissue injuries associated with distal radius fractures may influence strategies for the acute management of the fracture, but also may be a source of persisting pain and/or disability despite fracture healing. This article describes soft-tissue injuries and considerations for treatment associated with distal radius fractures, including injuries to the skin, tendon and muscle, ligaments, the triangular fibrocartilage complex, neurovascular structures, and related conditions such as compartment syndrome and complex regional pain syndrome.     

Does open fasciotomy contribute to morbidity and mortality after acute lower extremity ischemia and revascularization?

A retrospective review was undertaken of 127 lower extremity fasciotomies performed for compartment syndrome after acute ischemia and revascularization in 73 patients with vascular trauma and 49 patients with arterial occlusive disease. One hundred twelve (88%) fasciotomies were performed early (at the time revascularization); 15 (12%) were delayed because of late compartment syndrome diagnosis. Ninety-four (77%) patients had more than one accepted indication for fasciotomy. Double-incision fasciotomy was used in 98 (77%) extremities, single-incision fasciotomy was used in 19 (15%), and fasciotomy-fibulectomy was used in 10 (8%). Fasciotomies were closed in 88 (69%) patients an average of 14 days after surgery. Seven patients needed multiple skin grafting procedures or myocutaneous flaps to close the wound; none compromised limb salvage. Five other patients had minor wound infections that resolved. Functional status returned to preoperative levels by the time of discharge from the hospital in 59 (48%) patients. Thirty-one (24%) patients had residual lower extremity disability related to delayed union of the fracture (five), chronic neuropathy (20), leg swelling (one), or ischemic nonhealing fasciotomy wounds (three); two patients had unrelated disabilities. Fourteen (11%) amputations were required for refractory limb ischemia; two (1.6%) were required for wet gangrene of the foot, which infected the fasciotomy site; the others had open noninfected incisions. Eighteen (15%) patients died of cardiopulmonary failure or multisystem failure or both, without fasciotomy-related problems. Open fasciotomy for compartment syndrome after acute lower extremity ischemia and revascularization was associated with an increased risk of minor wound morbidity. However, limb loss and death resulted from persistent ischemia and underlying systemic disease processes or injuries, but not from open fasciotomy wound complications.
