LCPD - Legg - Calve - Perthes Disease

MRI - Magnetic Resonance Imaging

The Legg - Calve - Perthes disease (LCPD) is a juvenile form of idiopathic avascular necrosis of femoral head with an occurrence rate of 5.1 to 16.9 per 100,000 people. Despite numerous researches and trials and above a hundred year history, the numerous beliefs about the disease remain questionable [1]. In general, pathogenesis of the disease is attributed to the atrophy of the joint as a whole and the femoral head in particular.

Pharmacological sympathectomy in the form of a prolonged epidural analgesia at early stages of dystrophic processes is one of the possible options for restoring the nutritional balance in the femoral head [2]. Considering that avascular necrosis is accompanied with severe venous stasis and a high intraosseous pressure, blocking the sympathic innervation of veins of lower extremities may lead to their dilation and an increase of the venous shunt. As a consequence, it improves blood circulation, thus introducing a pathogenetic component to this type of therapy [3].

While the preventive [4] and therapeutic effect at early stages of treatment of the avascular necrosis of femoral head in children and adults [3] has already been proven, an extended parasympathetic blockade at later stages of the disease (let us call them intermediate stages preceding the healing stage) has not been studied. The purpose of this observation was to study the possibility of avoiding surgery among LCPD-affected children.

Material and Methods. Female patient M., 8 years old, was admitted to the orthopaedic department with complaints of pain in the left hip joint. The pain syndrome intensity increased with load and time (first symptoms were noticed 11 month before). The patient started limping. Both the child and the parents deny any preceding injury in the joint area or any cold-related diseases. Non-narcotic analgesic drugs administration allowed reducing the pain syndrome and limping for 4-8 hours, but then they re-emerged with the same intensity. The pain severity as per the VAS was 4.9 on the examination day.

A physical examination spotlighted an anatomical shortening of the

left femoral component by 1.5 cm along with a defence attitude and an insignificant internal rotation and bending in the hip joint. At that, flexion contracture was 175 degrees and external rotation contracture was about 5 degrees. When walking, the patient limped on her left foot in an effort to compensate for the functional (1.5 cm) and anatomical shortening, with her foot being in an equinus position. There was noted a deficit in external rotation up to 30 degrees (with the pain syndrome increase) and bending deficit of 20 degrees as compared to the function of the symmetrical joint. The deviation amplitude in both joints was on a par, but the left joint was apparently causing discomfort to the patient.

The two X-ray projection image showed destruction and reduction in the femoral epiphysis height (Fig. 1A, 1B). Its external outline was incongruent with the acetabulum, and only 77 % of the head was covered by the acetabulum. The pathology was also verified with the MRI. According to the Catterall classification [4], this stage of the process could be referred both to group II and group III of the disease. While the outcome in group II is favourable, the success rate in group III, according to T. Terjesen [5], is only 4 %. Nevertheless, considering that the lateral portion of epiphysis in our patient was to a degree preserved (without fragmentation), it inspired hope for its possible recovery during treatment. A. Ferguson [6]

Fig. 1. X-ray of left hip joint A - front plaine, impression and total involvement femoral head, and B - frog-leg position. Anterior part of femoral head is preserve, while posterior is impressed and has epyphisional cyst

assumed that if the lateral portion of the femoral head is preserved, then it becomes a sort of a «spacer» protecting the epiphysis central part from the body weight load. An experimental work by G. Rab et al. [7] has confirmed the assumption that the lateral column integrity of the femoral head forms a biomechanical basis for a favourable outcome of the Perthes disease. It gave occasion to apply a conservative treatment approach and to avoid surgery. Along with the clinical and functional assessment and visualisation of the joint's structures, we used instrumental procedures that allowed to track changes in blood circulation and conditions of tissues near the hip joint in real time. Micro-circulation near the hip joint was analysed using the LAKK-02 apparatus based on the laser doppler flowmetry principle. Obviously, we assessed only the para-articular structures condition (due to the limited functionality of the apparatus), but we did manage to obtain an indirect information on the changes in micro-circulation, including the osseous tissue. The quantitative values upon the patient's admission were as follows: perfusion (M)=1.9 mm/s, average perfusion fluctuation (6)=0.2 Hz, micro-circulation factor (Kv)=8.2. The results obtained were checked against the average age-matched normal values and the condition on the contralateral side, but for brevity we used only values relating the affected joint's area over time. Haemoglobin concentration in tissues was analysed with the use of the INVOS 5100 Somanetics device, Troy, Michigan, USA (rSo2). The initial assessment showed a concentration of 47 %. We recoursed to the global myography to analyze the muscular system condition by using the Neurosoft MVP-4 apparatus for the purpose. The amplitude value was 0.394 (A, mV), and frequency of voluntary quadriceps contractions was 102 (F, Hz). The child's parents consented to a minimally invasive treatment complemented with an extended drug-induced parasympathetic blockade. The treatment in compliance with the applicable legislation and respective ethical standards was performed.

Treatment Plan. In a clinical setting, a catheter was introduced into the epidural cavity on the L2-L3 level of the spine under Ketamine general anaesthesia in a proportion corresponding to the age and weight of the child. The skin was doubletunnelled with the catheter exiting on the level of the left midaxillary line with further attachment of the catheter using a sterile waterproof plaster. The catheter was connected to the Vogt medical 250 ml infusion pump. Ropivacaine 0.2 % drug was introduced at an initial flow rate of 6 ml/h for 12 hours per day. As early as 20 minutes after emergence from general anaesthesia the patient noted a warming sensation in the entire left extremity and numbness of skin when palpated. On that ground the infusion rate was reduced to 4 mm/h and maintained for the entire treatment period (8 days). Motion activity was preserved in full. Active rehabilitation, including exercises aimed at the recovery of the muscle mass in the left hip area, was started on the second day. The patient was permitted to walk with a load on the affected lower extremity limited to 50 %. No side effects or adverse events were observed.

Results and Discussion. The day before discharge from the in-patient clinic the catheter was removed and

the patient was subjected to the staged examination as per the above mentioned plan. Pain syndrome, according to the VAS rating, was 0. The joint's vicious position was entirely corrected, and the rotation range deficit in the left hip joint was reduced to 10 degrees. The proximity shortening remained within the limits of the epiphysis anatomical defect (15 mm). Microcirculation in tissues adjoining the affected hip joint was as follows: M=3.2 mm/s, 6=0.6 Hz, Kv=6.0. Haemoglobin concentration in tissues of the area under scrutiny reached 75 %. Changes in the electromyography data were insignificant, namely: A=0.395 mV, and the frequency of voluntary quadriceps contractions was 100 Hz. The patient was permitted to exert full load on the left hip joint only in three months upon the discharge from the in-patient clinic. A follow-up care allowed to ascertain the treatment effectiveness which was evidenced by the lack of any pain-related complaints, recovery of the left hip joint's motion range, gradual recovery of the correct motion pattern. The final examination was performed seven years after the treatment. Clinician-observed: equal length of lower proximities, full range of motion as compared to the healthy side. No pain syndrome. No gait abnormalities. Equal hip width. A better sphericity and full recovery of the femoral head's structure as evidenced by X-ray and MRI images (Fig. 2A, 2B; Fig. 3A, 3B). According to the data on micro-circulation in the tissues adjoining the left hip joint, the perfusion (M) was 4.8mm/s, average perfusion fluctuation (6)=0.8 Hz, micro-circulation factor (Kv)=4.5. Haemoglobin concentration in tissues remained equal to about 70 %. Myography data increased significantly, namely: the amplitude rose to 0.594 (A, mV), and frequency of voluntary quadriceps contractions rose to 247 (F, Hz).

The treatment of the female patient suffering from the LCPD in the intermediate stage (group II-III, according to Catterall) of the pathological process in the left hip joint made it possible to obtain good clinical and functional results. The increased motion range and pain management immediately after the therapy ensured an active rehabilitation conditioned by a temporary load limitation [1].

A consistent increase of the M and 6 values against the reduction of the Kv value immediately and in the long term after the treatment could indirectly indicate a micro-circulation improvement in the area under scrutiny. The oxygenation value sensitive to the haemoglobin

concentration in tissues adjacent to the hip joint almost doubled from 47 % to 75 % immediately after the treatment (rSo2).

The electromyography data progressively grew over time and with the patient's growing activity. The joint's elements visualisation using X-ray and MRI

imaging showed good result of the treatment as per the international system for assessing the severity of the LCPD.

According to the international studies covering a multitude of centres, there is a high percentage of the conservative treatment unsatisfactory outcome among the patients with the intermediate and final stages of LCPD [8, 9], while Russian publicationsreport a positive effect of peripheral blockades [2, 3, 4] which emphasizes the necessity to continue further studies in this field.

Conclusions. This clinical case allowed to demonstrate the possibilities of the prolonged epidural analgesia (parasympathetic blockade) in treating a female patient for the LCPD (intermediate stage). After 7 years the function of the affected hip joint is fully recovered. In addition, the sphericity of the femoral head was restored without pain syndrome.

A favourable outcome in the particular case leaves room for estimating positive prospects of a wider use of the prolonged epidural analgesia (parasympathetic blockade) method for treating this disease among children not only in early stages, but also in intermediate stages.

AA - Aplastic Anemia AC - Agranulocytosis ADR - Adverse Drug Reactions

Oneof the adversedrug reactions (ADR) duringthe treatment with Cephalosporin antibiotics (CA) are various cytopenias (thrombocytopenias, neutropenias/agranulocytosis, hemolytic anemias and, less often, pancytopenias). Cephalosporin-induced cytopenias can be based on two mechanisms - an immune and a myelotoxic one. Most publications on hematologic ADR in the course of treatment with CA, and ceftriaxone in particular, deal with the cases of neutropenias and agranulocytosis (AC) development. Analysis of these descriptions gives evidence of the possible (antibody-mediated) mechanism of ceftriaxone-induced AC [1]. One of the reports analyzes 14 verified cases of ceftriaxone-induced agranulocytosis. The main mechanism for the development of agranulocytosis is the immune mechanism, since in most cases there was no

inhibition of erythropoiesis and thrombocytopoiesis [2]. However, bone marrow (BM) involvement was found in none of the cases, which was taken notice of in other - earlier - studies. Myelotoxic effect of p-Lactam antibiotics was discovered during the experimental studies in the course of in vitro granulopoiesis and monocytopoiesis cell culture, and along with this, a dose-dependent effect, most prominent with ceftriaxone and ceftazidime, was found [3].

In the analysis of cases of neutropenia caused by cephalosporin antibiotics (ceftaroline), the relationship between the duration of drug use and the frequency of neutropenia was established. The bone-marrow (BM) hemopoiesis picture was characterized by the absence of highly-differentiated granulocytic lineage cells, with the presence of numerous granulocyte progenitor cells
