[Outcomes of multilevel orthopedic surgery in children with cerebral palsy]. / Serebral palsili çocuklarda çok seviyeli ortopedik cerrahi tedavinin sonuçlari.

OBJECTIVES: Outcomes of single-event bilateral multilevel orthopedic surgery in children with cerebral palsy were retrospectively investigated by physical findings, and gross motor function measurement (GMFM) score in all patients and additionally by joint kinematics, and time-distance parameters in ambulatory patients. PATIENTS AND METHODS: A total of 24 patients (17 ambulatory; 7 non ambulatory; mean age 12 years; range 5 to 19 years) treated with multilevel orthopedic surgery between December 2003 and December 2005 were included in the study. Patients were evaluated with physical examination and GMFM score. In addition, computed gait analysis was used to evaluate joint kinematics and time-distance parameters in ambulatory children. The following surgeries were performed on the children in the study cohort: adductor tenotomy (n=24); psoas lengthening (n=14); hamstring lengthening (n=46); distal rectus femoris transfer (n=18); bilateral Achilles tendon lengthening (n=22); distal femoral derotation osteotomy (n=1); open reduction and Dega osteotomy (n=1), and proximal femur resection (n=2). Patients were evaluated with the same parameters after an average of eight months postoperatively. The pre- and postoperative results were statistically compared. RESULTS: Improvements were achieved in the lying-rolling (7%), sitting (9%), crawling-kneeling (7%), standing (5%), and walking-running-jumping (5%) activities of GMFM score. An increase in hip abduction angle and external rotation and a decrease in the Thomas test results were observed. A decrease in popliteal angle and an increase in active and passive knee extension were provided. Active and passive ankle dorsiflexion increased. In the kinematic parameters, the minimum hip and knee flexions in the stance phase were significantly decreased, while no significant decrease was seen in the maximum hip and knee flexion in the swing phase. Both the ankle dorsiflexion in the stance and swing phase and the time-distance parameters consist of walking velocity, stride length and the cadence were significantly improved. CONCLUSION: Single-event bilateral multilevel orthopedic surgery performed in the right indication was shown to be effective with improvements in physical examination findings GMFM scores, joint kinematics and time-distance parameters in children with cerebral palsy.

Severe heterotopic ossification in the non-affected limbs of a hemiplegic patient with traumatic brain injury.

BACKGROUND/OBJECTIVE: Heterotopic ossification characterized by new bone formation in the periarticular regions of large joints in patients with neurologic injury most commonly occurs on the neurologically involved side. This study presents a very rare localization of heterotopic ossification that developed in the non-paretic limbs of a hemiplegic patient with traumatic brain injury (TBI). CASE REPORT: A 25-year-old left hemiplegic male with TBI due to a gunshot wound was admitted to the rehabilitation centre after a 2.5-month period of coma in the intensive care unit. He had limited range of motion accompanied by pain in the bilateral hip, bilateral elbow and right knee joints. Neurological examination revealed upper motor neuron lesions only on the left side in neurological exam. Plain radiographs of the involved joints revealed bilateral heterotopic ossification, which was more severe on the non-paretic side. DISCUSSION: Clinicians should keep in mind that heterotopic ossification can occur in non-hemiplegic extremities as well as hemiplegic extremities in patients with TBI in whom the extent of neurologic damage cannot be definitely established.

Outcomes of combined hamstring release and rectus transfer in children with crouch gait.

BACKGROUND: Our aim was to evaluate the outcomes of combined hamstring release and rectus transfer in children with crouch gait using physical examination and gait analysis. MATERIALS AND METHODS: A total of 19 patients (38 knee joints) with crouch were evaluated by static examination and computerized analysis with dynamic EMG. The Ely test was positive together with prolonged and increased activity in the rectus muscle bilaterally in all patients. These patients underwent hamstring release and rectus transfer. Intensive rehabilitation was provided following the surgery and the patients were evaluated again by static examination and gait analysis after an average of 6.3 (4-7.5) months after surgery. The preoperative and postoperative static examination findings, knee and ankle joint kinematics and time-distance parameters were compared in 19 children. RESULTS: There was a significant improvement in static examination findings, knee and ankle kinematics and time-distance parameters. However, there was no significant difference between the preoperative and postoperative swing phase peak knee flexion. CONCLUSIONS: This study demonstrated that static parameters, time-distance parameters, knee and ankle kinematics were improved following combined hamstring release and rectus transfer in children with cerebral palsy without any cases of stiff knees.

The effect of gabapentin in earlier stage of reflex sympathetic dystrophy.

The objective of this paper is to investigate the effect of gabapentin in the earlier stage of reflex sympathetic dystrophy syndrome (RSD). Twenty-two patients diagnosed with RSD were enrolled. Initial gabapentin dosage was 600 mg/day. This dosage is increased gradually until a satisfactory pain level was reached. After this level, this dosage was maintained throughout the study. An exercise program was also applied to the patients. Provoked and static pain scores of the patients were obtained initially, at 3-day intervals for maintenance dosage determining, and at 6 weeks after the discharge. Functional improvement parameters were volumetric measurement; dynamometric measurement and third finger pulp-distal palmar crease distance measurement for hands; and metric circumferential measurement and range of motion for elbow, knee, and foot initially, at baseline, on the tenth day, upon discharge, and 6 weeks after the discharge. The mean maintenance dose of gabapentin was 1,145.46+/-377.6 mg/day (range, 900-1,800 mg/day). Improvements in spontaneous and provoked pain intensities were statistically significant. No statistically significant difference was obtained in functional improvement parameters. Dizziness in three patients, headache in two patients, and mild burning feeling in the tongue in one patient were the reported side effects. These symptoms resolved spontaneously in few days. Gabapentin cannot be recommended as the drug of choice, but it may be considered as one of the therapeutic alternatives in the management of pain due to RSD. We suggest that it is effective only for the pain and not for other symptoms of RSD. Serious side effects that will cause the patient to stop using the drug are rare.

Effect of isokinetic training on strength, functionality and proprioception in athletes with functional ankle instability.

The purpose of this study was to investigate the effects of isokinetic exercise on strength, joint position sense and functionality in recreational athletes with functional ankle instability (FAI). Strength, proprioception and balance of 24 recreational athletes with unilateral FAI were evaluated by using isokinetic muscle strength measurement, ankle joint position sense and one leg standing test. The functional ability was evaluated using five different tests. These were; single limb hopping course (SLHC), one legged and triple legged hop for distance (OLHD-TLHD), and six and cross six meter hop for time (SMHT-CSMHT). Isokinetic peak torque of the ankle invertor and evertor muscles were assessed eccentrically and concentrically at test speeds of 120 degrees /s. Isokinetic exercise protocol was carried out at an angular velocity of 120 degrees /s. The exercise session was repeated three times a week and lasted after 6 weeks. At baseline, concentric invertor strength was found to be significantly lower in the functionally unstable ankles compared to the opposite healthy ankles (p < 0.001). This difference was not present after executing the 6 weeks exercise sessions (p > 0.05). Ankle joint position sense in the injured ankles declined significantly from 2.35 +/- 1.16 to 1.33 +/- 0.62 degrees for 10 degrees of inversion angle (p < 0.001) and from 3.10 +/- 2.16 to 2.19 +/- 0.98 degrees for 20 degrees of inversion angle (p < 0.05) following the isokinetic exercise. One leg standing test score decreased significantly from 15.17 +/- 8.50 to 11.79 +/- 7.81 in the injured ankles (p < 0.001). Following the isokinetic exercise protocol, all of the worsened functional test scores in the injured ankles as compared to the opposite healthy ankles displayed a significant improvement (p < 0.01 for OLHD and CSMHT, p < 0.001 for SLHC, TLHD, and SMHT). These results substantiate the deficits of strength, proprioception, balance and functionality in recreational athletes with FAI. The isokinetic exercise program used in this study had a positive effect on these parameters.

Comparison of the efficacies of botulinum toxin A and Johnstone pressure splints against hip adductor spasticity among patients with cerebral palsy: a randomized trial.

OBJECTIVE: The goal was to compare the efficacies of botulinum toxin A (BTX) treatment and Johnstone pressure splint (JPS) treatment against hip adductor muscle spasticity among children with spastic diplegic cerebral palsy. METHODS: For each patient in the BTX group, a total of 300 IU of BTX was injected into adductor and medial hamstring muscle groups. In the JPS group, long leg JPS were administered for 30 minutes 3 days per week. Bobath neurodevelopmental exercises were administered to both groups 3 days per week during the study period. All cases were assessed by using gross motor function measurements, passive hip abduction goniometric measurements, modified Ashworth Scale scores, and measurements of the distance between the knees as indicator variables. RESULTS: We found that there was statistically significant improvement in all indicators for both groups. BTX treatment was found to be superior to JPS treatment in terms of the indicator variables of our study.

Efficacy of isokinetic exercise on joint position sense and muscle strength in patellofemoral pain syndrome.

OBJECTIVE: The objective of this study was to demonstrate the impairment of knee joint position sense in individuals with patellofemoral pain syndrome and investigate the effects of isokinetic exercise on knee joint position sense and muscle strength. DESIGN: A total of 24 male patients complaining of anterior knee pain caused by overexertion and 24 male healthy individuals without symptoms were included for this investigation. Isokinetic exercise protocol was carried out at angular velocities of 60 degrees/sec and 180 degrees/sec. These sessions were repeated three times per week and lasted for 6 wks. At the beginning and after 6 wks of knee passive joint position sense, quadriceps and hamstring muscle strength and pain assessments were performed. RESULTS: After the isokinetic exercise, flexion peak torque (P < 0.05), extension peak torque (P < 0.01), flexion total work (P < 0.001), extension total work (P < 0.001), passive reproduction of knee joint position sense for 40 degrees of flexion (P < 0.05) and 50 degrees of extension (P < 0.01), and pain score (P < 0.001) improved significantly in the patellofemoral pain syndrome group. CONCLUSION: Isokinetic exercises have positive effects on passive position sense of knee joints, increasing the muscular strength and work capacity. These findings show that using the present isokinetic exercise in rehabilitation protocols of patients with patellofemoral pain syndrome not only improves the knee joint stabilization but also the proprioceptive acuity.

Clinical significance of congenital lumbosacral malformations in young male population with prolonged low back pain.

STUDY DESIGN: A prospective clinical investigation. OBJECTIVE: To determine the clinical significance of congenital lumbosacral malformations in young male patients with subacute or chronic low back pain and to investigate a possible worsening of the clinical picture with the concurrence of transitional vertebra (TV) or spina bifida occulta (SBO). SUMMARY OF BACKGROUND DATA: Although the causative roles of congenital malformations in low back pain and lumbar disc herniation have been investigated, there is no study that compares the incidence of congenital malformations in prolonged low back pain between radicular and nonradicular groups; nor is there a study that compares the pain intensity between the groups with and without congenital malformations. METHODS: Lumbosacral plain radiographs of 881 young male patients with low back pain lasting for >4 weeks were evaluated. For all patients, we recorded the clinical signs and their pain intensities based on a 10-cm visual analog scale (VAS). RESULTS: Congenital lumbosacral malformations were determined in 88 of 881 patients. Of these, 48 were TV, 38 were SBO, and 2 were a combined lesion of TV and SBO. The difference in positive clinical sign and VAS was statistically significant (P < 0.05) between the groups with and without congenital lumbosacral malformations. In contrast to SBO, there was a statistically significant difference of TV incidence between the sign positive and the sign negative groups (P < 0.05). The difference in VAS values was statistically significant for both TV and SBO (P < 0.001). CONCLUSIONS: The results of this study show that SBO and TV increase the severity of the clinical picture whether or not they have a causal relationship. Additionally, transitional vertebrae seem to increase nerve-root symptoms whereas spina bifida occulta does not.

Peak and end range eccentric evertor/concentric invertor muscle strength ratios in chronically unstable ankles: comparison with healthy individuals.

The aim of this study was to evaluate the alterations in eccentric evertor/concentric invertor strength ratio and their importance in the chronically unstable ankle. Eight patients with chronic ankle instability (CAI) and nine healthy individuals participated in this study. Isokinetic concentric and eccentric invertor and evertor muscle strength measurement was carried out at an angular velocity of 120°·sec(-1) by measuring maximal force moments (torque) during isokinetic ankle inversion and eversion movements. Functionally, evertor/invertor muscle strength ratios (E/I strength ratio) were calculated separately based on peak moment and angle-specific moments obtained at 0°, 5°, 10°, 15°, 20° ankle joint angles. Peak and angle-specific eccentric evertor strength values at 0°, 5°, 10°, 15°, 20° were significantly lower in the chronic ankle instability (CAI) group. In spite of this, no differences were obtained for peak and angle-specific concentric invertor torque values. Eccentric evertor/concentric invertor strength (Eecc/Icon) ratios were also significantly lower in the CAI group, but only at 15° and 20°. Eccentric evertor muscle torque and end range (15°-20°) Eecc/Icon strength ratio for the chronically unstable ankle were significantly different from those for the healthy ankle. For this reason, measurements of end range eccentric/concentric strength ratios are more valuable in monitoring chronic ankle injuries and rehabilitation should include not only concentric muscle strengthening but also eccentric muscle strengthening, particularly for the evertor muscles.
