RESUMEN

Purpose: Above-knee casts pose a major challenge in the day-to-day activities among walking age clubfoot patients due to complete restriction of knee movement. This current study investigates the effectiveness of below-knee casts compared to above-knee casts for managing walking age clubfoot deformity. Methods: After approval from the institutional ethical committee, we enrolled walking age clubfoot patients for deformity correction through corrective manipulation and casting through below-knee casts over 2 years. The corrective manipulation was performed using the Ponseti technique. The patients were followed for a minimum of 2 years period. To compare the effectiveness of below-knee casts over above-knee casts, we enrolled equal numbers of walking age clubfeet matched for age and gender. We compared the two groups in terms of initial and post-correction Dimeglio scores, individual deformities corrections (maximum ankle dorsiflexion, heel varus correction, foot abduction), failure rates, relapses, and complication rates. Results: 56 patients with 80 clubfeet with a mean follow-up of 39.98 months were considered for the final analysis. There were 29 patients in the below-knee cast group and 27 in the above-knee cast group, with 40 clubfeet each. The patients in the above-knee casting group had significantly better post-correction Dimeglio scores and individual deformity components corrections than the below-knee cast group. There were nil failures in the above-knee casting group and 7.5% in the below-knee cast group. The relapse rate was 15% in both groups, with none requiring any extensive soft tissue procedure. We did not encounter any major complications during the treatment and follow-up. Conclusion: The deformity correction and maintenance are suboptimal with the below-knee casts. Therefore, above-knee casts should be the preferred management modality for correction of walking age clubfoot deformities.

RESUMEN

CASE: A 40-year-old man presented with spontaneous, atraumatic right groin pain and inability to bear weight secondary to an isolated avulsion of the right lesser trochanter. Magnetic resonance imaging of the affected hip was suggestive of an infection, and a computed tomography-guided biopsy was remarkable for Mycobacterium tuberculosis, which was successfully managed with antitubercular therapy and activity modification. CONCLUSION: Although an isolated spontaneous avulsion of the lesser trochanter is typically pathognomonic for malignancy, an infectious etiology, such as tuberculosis, should also be considered in the differential diagnosis.

RESUMEN

BACKGROUND: Genu Valgum usually originates from distal femur and many open and closed wedge osteotomies of distal femur have been reported but none has proved to be the best. Distal femur V osteotomy is a wedgeless osteotomy and is a rarely reported osteotomy with only a few case series and 167 cases of isolated distal femur V osteotomy for genus valgum in young patients (<25 years) in literature but with a tendency to have an excellent outcomes. PURPOSE: To determine correction and clinical outcome following V osteotomy for genu valgum in adolescents and young adults (10-25 years). PATIENT AND METHODS: A systematic research was conducted of PubMed, MEDLINE and Google Scholar to identify studies reporting the correction and clinical outcome following V osteotomy in adolescents and young adults (10-25 years) for genu valgum by 2 different authors according to PRISMA guidelines. RESULTS: 5 studies with 167 patients and 263 knees were identified meeting the inclusion criteria for review. The follow-up period ranged from 3 months to 36 months. Overall complication rate was 12.3%, the most common being plaster sore, 4.2% (11/263) followed by superficial infection, 2.7% (7/263). The mean correction was 19.1° and a mean post-operative valgus was 5.7°. In those compared with Bostman score (157/167), 94.3% had excellent (148/157) and remaining 5.7% (9/157) had good scores (20-27/30) with none showing poor score (<20/30). CONCLUSION: V osteotomy is a reliable method of distal femoral osteotomy to attain a good correction with an excellent clinical outcome even with variations of fixation however longer follow-up period are required for better evaluation of recurrence.

RESUMEN

Introduction Neglected clubfoot comprises clubfoot deformities with late presentation and weight-bearing on the affected foot. These deformities are stiff and need an aggressive approach for cast-based management. The modified versions of the Ponseti technique have been found effective in treating these deformities. However, these techniques' long-term outcomes in neglected clubfoot and related correction maintenance with time progression have not been investigated. The current study aims to analyze the changes in deformity correction after a minimum of two years of follow-up in neglected clubfeet treated with a modified Ponseti method of corrective casting. Methods We retrospectively analyzed the clinical records of 25 patients with 38 neglected clubfeet with a mean follow-up of 37.9±4.1 months after the initial correction of the deformity. These patients were managed with a modified Ponseti technique. The modified technique incorporated simultaneous deformity manipulation before equinus correction and additional dorsiflexion manipulation after two weeks of tendo-achilles tenotomy. The Pirani and Dimeglio scores and individual deformity corrections at the final follow-up were compared with those at final cast removal. Results No significant differences were observed between the initial and the final follow-up Pirani and Dimeglio scores. Concerning the deformity correction parameters, there was a significant loss in heel varus and foot abduction correction. However, the change in these parameters was small (less than 3 degrees). Conclusion The neglected clubfoot deformity can be satisfactorily corrected with an aggressive Ponseti based corrective manipulation and casting at a low relapse rate. However, minor loss of deformity correction is noticed after two years of treatment which is not reflected in clinical scores. Therefore, a strict long-term follow-up and careful deformity assessment are required to predict the recurrence in these cases.

RESUMEN

PURPOSE OF STUDY: Planovalgus deformity in cerebral palsy is disabling for the child in terms of increased energy expenditure during the gait cycle. The lever arm function of the foot is lost due to midfoot break and the achilles tendon is at a disadvantage being unable to lift the body weight during push-off. We evaluated the results of calcaneal lengthening osteotomy in such patients with clinical, radiological and gait parameters. METHODS: 17 spastic feet in a sample of 10 children were included in our study. The children were classified according to the GMFCS classification system and clinical parameters such as heel valgus and heel rise tests, radiological angles such as Talo-calcaneal angle and Talo-navicular coverage angle on AP view and Calcaneal pitch angle, calcaneus-5th metatarsal angle and talus-1st metatarsal angle on lateral view were measured. Video gait analysis was performed to observe knee progression angle in mid stance and peak knee flexion angle in mid and terminal stance. RESULTS: Improvement was noted clinically in the heel valgus angle (preop-12.06°, postop-5.12°) and radiological parameters showed an improved coverage of the talus by navicular with simultaneous lifting of the medial longitudinal arch. Gait analysis showed decreased knee flexion trend in mid and terminal stance phase with better restoration of the knee axis. CONCLUSION: Calcaneal lengthening osteotomy with peroneus brevis lengthening corrects almost all aspects of planovalgus deformity with an improved gait pattern without disturbing joint range of motion. It is a safe procedure for GMFCS grade 1 and 2 patients without much complications.

RESUMEN

INTRODUCTION: Spasticity has been considered to be a main contributor to both the impairment of function as well as posture in children with cerebral palsy (CP). Patterns of upper limb motor involvement in CP vary with resultant limitations in daily independence, participation, and quality of life. Botulinum Toxin-A (BTX-A) is a potent neurotoxin which acts by preventing the release of acetylcholine (Ach) from presynaptic axon at motor end plate reducing focal spasticity. With literature established role of BTX-A available for lower limb spasticity in CP, the purpose of this study was to present an objective analysis of the effect of a single i.m. injection of BTX-A in reduction of spasticity in the upper limb as well as functional outcome in children (4-12yrs) with spastic CP. METHODS: A total of 28 patients (30 upper limbs) of spastic CP with minimum follow up of 6months were included in the study. Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) were used to measure the spasticity. Surface landmarks were used to give I.m. Botox in selected spastic muscles followed by targeted rehabilitation. Functional outcomes were measured by MACS (Manual Ability Classification System) and Canadian Occupational Performance Measure (COPM) before treatment, at 3 and 6 months follow up. RESULTS: Pronator teres was the most frequently injected muscle followed by FCU and Adductor pollicis. MAS scores at all joints and MTS scores at forearm deteriorated between 3 and 6 months. However, MACS and COPM showed sustained improvement at 3months and 6months with statistically significant change. CONCLUSION: I.m. BTX-A injected using anatomical landmarks had significant improvement in both clinical and functional outcome measures. We noticed significant improvement in MACS and COPM at 6 months despite return of local spasticity. It is safe and effective for spasticity of upper limbs in cerebral palsy and capable of improving function without major side effects. MACS & COPM are easy to use, less time consuming & easily adjusted to local needs. Randomized control trials with long follow up are required in future with special focus on dosing and timing, scoring system for functional outcome as per regional needs and issue for antibody formation for repeat injections of BTX-A.

RESUMEN

INTRODUCTION: Serial Ponseti casting achieves deformity correction in early presenting idiopathic clubfoot cases normally in around 7 casts. However, there are resistant patients where correction requires more casts than usual. In such patients a modification in standard technique might be required right from the beginning. Such patients were collectively called as difficult clubfoot. The aim of this study was to assess the outcome of our modification to Ponseti technique in difficult clubfoot. METHODS: All idiopathic clubfoot cases who were 75th percentile or more in WHO age for weight chart (chubby infants) or untreated clubfoot patients presenting for first time to our clinic at more than 5 months age (late presenters and neglected cases) were included in the study. Patients who had been previously surgically intervened elsewhere, patients over 7 years of age, patients with syndromic clubfoot or clubfoot associated with neurological conditions were excluded from the study. The patients were treated by early tenotomy of tendoachillis and a plantar fascia release before starting serial casting by Ponseti technique. Post correction, strict bracing protocol was followed with regular follow up. Pirani scoring was done at each stage. Measurement of Talocalcaneal angle on AP radiograph, maximum degree of abduction and dorsiflexion was noted once every year. RESULTS: There were total 28 patients in our study. In all, 47 feet were subjected to modified Ponseti protocol. There were 21 male patients. Median age at presentation was 4 months. Mean centile of weight for age as per WHO growth chart was 64. Mean Pirani score at presentation was 5.86 (S.D. ±â€¯0.34). Mean number of casts required for correction was 3.75 ±â€¯1.10. Maximum followup period was 25 months. CONCLUSION: This modification of Ponseti casting for difficult clubfoot patients achieves correction in shorter duration with less number of casts.

RESUMEN

INTRODUCTION: Bilateral Tubercular Dactylitis (TD) is an unusual presentation of tuberculosis and only handful numbers of cases are reported in the literature. Hence, very little is known about its clinical presentation, statistic, radiological features and its outcome. METHODS: We have included seven male and two female patients of mean age 7.2 years, of the proven cases of bilateral TD by histopathological or microbiological or PCR analysis from core biopsy. Radiological features were recorded from plain radiograph. All patients were given Antitubercular drugs according to WHO 2010 recommendation (four drugs for 3-5 months, three drugs for next 3-5 months and finally two drugs for 6-8 months). Debridement was done whenever required. RESULTS: Of total 26 lesions, the most common presentation was swelling with or without mild pain. Discharging sinus was present in four lesions. There were six phalanges, 18 metacarpal and two metatarsals. Radiographically, the most common type of lesion was soft tissue swelling followed by lytic lesion. Histopathologically tuberculosis was proven in 10 (55.6%) lesions, bacteria isolated in 5 (27.8%) lesions and PCR was done in 8 lesions and was positive in all. All lesions healed after giving ATT except one which developed psudo-arthrosis and one patient developed coronal plane deformity that was corrected by JESS. CONCLUSION: A clinician should always suspect tuberculosis while dealing with a pathology of hand and feet even if it is bilateral. Suspected case can be diagnosed by histopathological, microbiological or PCR analysis and it can be treated by ATT with a good functional outcome.

RESUMEN

BACKGROUND: Medial close wedge, lateral open wedge, dome and "V" osteotomies are the commonly to correct the genu valgum (GV) deformity. However, the ideal method for the correction of coronal plane deformity is controversial. This prospective study is to evaluate the functional and radiological result of supracodylar "V" osteotomy to correct GV deformity. MATERIALS AND METHODS: "V" osteotomy was done in all patients with clinically significant GV deformity and was fixed with crossed K-wires. Weight-bearing mobilization was started after radiological union. Patients were evaluated for correction in different clinical and radiological parameters. The function of the knee was assessed by Bostman's score. The subjective score was used to assess the parent's satisfaction after the procedure. RESULTS: 187 limbs with genu valgum deformity (47 males and 71 females) were included in this study. We observed a significant improvement in the mean intermalleolar distance, clinical and radiological tibiofemoral angle and lateral distal femoral angle, from 17.3 to 3.9 cm, 23.8°to-4.5°, 25.6° to 6.1°, 76.6° to 88.4°, respectively. The mean Bostman score improved from 20.6 to 28.1. The parent's satisfaction assessed subjectively was 95.3 points. CONCLUSION: This osteotomy along with the fixation with K-wires is a safe, effective, reproducible technique with a short learning curve and a procedure requiring no repeat surgery for implant removal, with good functional results, and without major complications.

RESUMEN

The incidence and risk factors of distal tibia/fibula fracture, an uncommon complication during Ponseti manipulation, are unknown. We evaluated 222 virgin clubfeet of patients aged less than 3 years for fractures of distal tibia/fibula. Incidence rate was found to be 1.3% per year. Associated risk factors were identified as neglected, syndromic clubfeet, feet requiring greater than 10 casts, post-tenotomy dorsiflexion less than 10° and casting by physician with less than 3 years of casting experience, with odds ratios of 14, 28, 4.9, 3.7 and 3.4, respectively. Most of these fractures healed without consequences; however, it is still advisable not to forcefully dorsiflex while casting, which may result in the fracture of distal tibia/fibula.

RESUMEN

INTRODUCTION: Defective mineralization of osteoid matrix prior to physeal closure causes rickets. Poor calcification of the cartilage matrix in the zone of provisional calcification causes flattened skull, rachitic rosary, bowed legs, coxa vara and brittle bones. The recent literature has seen an increase in the incidence of the disease in both developing and developed nations. We evaluated behaviour of lower limb deformities due to nutritional rickets in 117 patients. MATERIALS AND METHODS: A prospective study was conducted from January 2009 to December 2011 for clinical and radiological evaluation of knee deformities in nutritional rickets. A total of 117 patients with 198 coronal plane knee deformities between 2 years and 12 years age of rickets were enrolled in this study. RESULTS: In our study, there were 65 genu varum and 133 genu valgum deformities. Seven genu varum (10.7%) and 37 genu valgum (28%) deformities were regarded as failure. Fifty eight genu varum got corrected completely obtaining an average of 5° of valgum in an average of 6.3 months. The average rate of spontaneous correction was 1.9° a month. Ninety six valgum got corrected obtaining an average of 4.7 valgum in an average of 13.3 months. The average rate of spontaneous correction was 0.92° a month. CONCLUSION: Most of the rachitic deformities get corrected with age. Genu varum is having better chances and a faster rate of correction as compared with genu valgum. Early surgery may be indicated in late presenting cases. We believe varum above 4 years and 18° of valgum above 9 years usually do not correct and may require surgical intervention.

RESUMEN

BACKGROUND: Gentle passive manipulation and casting by the Ponseti method have become the preferred method of treatment of clubfoot presenting at an early age. However, very few studies are available in literature on the use of Ponseti method in older children. We conducted this study to find the efficacy of Ponseti method in treating neglected clubfoot, which is a major disabler of children in developing countries. MATERIALS AND METHODS: 41 clubfeet in 30 patients, presenting after the walking age were evaluated to determine whether the Ponseti method is effective in treating neglected clubfoot. This is a prospective study. Pirani and Dimeglio scoring were done for all the feet before each casting to monitor the correction of deformity. Quantitative variables were expressed as mean ± standard deviation and compared between preoperative and postoperative followup using the paired t-test. Also, the relation between the Pirani and Dimeglio score, and age at presentation with the number of casts required was evaluated using Pearson's correlation coefficient. No improvement in Dimeglio or Ponseti score after 3 successive cast was regarded as failure of conservative management in our study. RESULTS: The mean age at presentation was 3.02 years (range 1.1 - 10.3 years). The mean followup was 2.6 years (range 2-3.9 years). The mean number of casts applied to achieve final correction were 12.8 casts (range 8 - 18 casts). The mean time of immobilization in cast was 3.6 months. The mean Dimeglio score before treatment was 15.9 and after treatment were 2.07. The mean Pirani score was 5.41 before treatment and 0.12 after treatment. All feet (100%) achieved painless plantigrade feet without any extensive soft tissue surgery. 7 feet (17%) recurred in our average followup of 2.6 years. CONCLUSIONS: Painless, supple, plantigrade, and cosmetically acceptable feet were achieved in neglected clubfeet without any extensive surgery. A fair trial of conservative Ponseti method should be tried before resorting to extensive soft tissue procedure.

RESUMEN

PURPOSE: To compare two commonly used methods of temporary hemiepiphysiodesis (staples and figure of eight plate) in the management of coronal plane deformities of the knee in skeletally immature children. METHODS: This prospective study was conducted between November 2012 and November 2015. A total of 40 patients with 67 affected knee joints, having at least 1 year of skeletal growth remaining, were included in the study. Angular correction was measured by recording the mechanical lateral distal femoral angle (mLDFA), mechanical medial proximal tibial angle (mMPTA), and anatomical tibio-femoral angle (TFA) (for the overall alignment of lower limbs). Implant removal was done after 5° of overcorrection was achieved. The rate of correction (° per month) and complications related to each technique were recorded. RESULTS: The most common diagnosis was idiopathic genu valgum. The overall rate of correction (TFA) was 1.2° for staples and 1.4° for eight plate (p = 0.70, not statistically significant). The correction in mLDFA was statistically better in the eight plate group, whereas an opposite trend was recorded in mMPTA. Implant-related complications were present in two cases of the staples group. CONCLUSION: Although the overall correction rate was similar in both groups, implant-related complications were lower with figure of eight plate. In idiopathic genu valgum (the most common diagnosis), the correction was statistically better in the eight plate group. We recommend figure of eight plate over staples in managing these deformities.

RESUMEN

Tuberculosis, or phthisis (consumption) as it was popularly known in the Greek era, has been endemic in Southeast Asia and Sub-Saharan Africa; however, the human immunodeficiency virus epidemic has seen the re-emergence of this disease in the areas in which it was not very commonly reported. With this, the need for understanding and treatment of rare presentations of tuberculosis has become of paramount importance to achieve the World Health Organization millennium goal of a "reversal of incidence by 2015." Foot involvement has been reported in 0.1% to 0.3% of extrapulmonary cases. Multifocal lesions have an incidence of <10% in osteoarticular tuberculosis. Bilateral feet involvement in multifocal tuberculosis has not yet been reported in either children or adults in published studies. We report a case of tuberculosis with lesions in the bilateral metatarsals, the occurrence of which is very rare. The diagnosis was mainly histopathologic owing to the paucibacillary nature of the disease. Early identification and treatment with antitubercular drugs will normally result in a good cosmetic and functional result.

RESUMEN

We report Ogilvie's syndrome following posterior spinal arthrodesis on a patient with thoracic and lumbar scoliosis associated with intraspinal anomalies. Postoperative paralytic ileus can commonly complicate scoliosis surgery. Ogilvie's syndrome as a cause of abdominal distension and pain has not been reported following spinal deformity correction and can mimic post-surgical ileus. 12 year old female patient with double thoracic and lumbar scoliosis associated with Arnold-Chiari 1 malformation and syringomyelia. The patient underwent posterior spinal fusion from T4 to L3 with segmental pedicle screw instrumentation and autogenous iliac crest grafting. She developed abdominal distension and pain postoperatively and this deteriorated despite conservative management. Repeat ultrasounds and abdominal computer tomography scans ruled out mechanical obstruction. The clinical presentation and blood parameters excluded toxic megacolon and cecal volvulus. As the symptoms persisted, a laparotomy was performed on postoperative day 16, which demonstrated ragged tears of the colon and cecum. A right hemi-colectomy followed by ileocecal anastomosis was required. The pathological examination of surgical specimens excluded inflammatory bowel disease and vascular abnormalities. The patient made a good recovery following bowel surgery and at latest followup 3.2 years later she had no abdominal complaints and an excellent scoliosis correction. Ogilvie's syndrome should be included in the differential diagnosis of postoperative ileus in patients developing prolonged unexplained abdominal distension and pain after scoliosis correction. Early diagnosis and instigation of conservative management can prevent major morbidity and mortality due to bowel ischemia and perforation.

RESUMEN

A new era in the surgical treatment of adolescent idiopathic scoliosis (AIS) opened with the introduction of pedicle screw instrumentation, which provides 3-column vertebral fixation and allows major deformity correction on the coronal, sagittal, and axial planes. A steep learning curve can be expected for spinal surgeons to become familiar with pedicle screw placement and correction techniques. Potential complications including injury to adjacent neural, vascular, and visceral structures can occur due to screw misplacement or pull-out during correction maneuvers. These major complications are better recognized as pedicle screw techniques become more popular and may result in serious morbidity and mortality. Extensive laboratory and clinical training is mandatory before pedicle screw techniques in scoliosis surgery are put to practice. Wider application, especially in developing countries, is limited by the high cost of implants. Refined correction techniques are currently developed and these utilize a lesser number of pedicle anchors which are strategically positioned to allow optimum deformity correction while reducing the neurological risk, surgical time, and blood loss, as well as instrumentation cost. Such techniques can be particularly attractive at a time when cost has major implications on provision of health care as they can make scoliosis treatment available to a wider population of patients. Pedicle screw techniques are currently considered the gold standard for scoliosis correction due to their documented superior biomechanical properties and ability to produce improved clinical outcomes as reflected by health-related quality-of-life questionnaires. Ongoing research promises further advances with the future of AIS treatment incorporating genetic counseling and possibly fusionless techniques.

RESUMEN

Femoral shortening has an advantage of gaining reduction in severe grades of congenital dislocation of the knee joint without release or lengthening of the quadriceps tendon, thereby reducing the incidence of extensor lag. We report our mid-term functional results in six patients (10 knees) with grade III congenital dislocation of the knee joint who were treated with femoral shortening. At an average follow-up of 4.1 years, the mean active range of motion was -0.5 to 107° and none of the patients had extensor lag. The results in arthrogryposis multiplex congenita were noteworthy for the absence of extensor weakness, postoperative deformity, or recurrence.

RESUMEN

Adolescent idiopathic scoliosis is the most common spinal deformity encountered by General Orthopaedic Surgeons. Etiology remains unclear and current research focuses on genetic factors that may influence scoliosis development and risk of progression. Delayed diagnosis can result in severe deformities which affect the coronal and sagittal planes, as well as the rib cage, waistline symmetry, and shoulder balance. Patient's dissatisfaction in terms of physical appearance and mechanical back pain, as well as the risk for curve deterioration are usually the reasons for treatment. Conservative management involves mainly bracing with the aim to stop or slow down scoliosis progression during growth and if possible prevent the need for surgical treatment. This is mainly indicated in young compliant patients with a large amount of remaining growth and progressive curvatures. Scoliosis correction is indicated for severe or progressive curves which produce significant cosmetic deformity, muscular pain, and patient discontent. Posterior spinal arthrodesis with Harrington instrumentation and bone grafting was the first attempt to correct the coronal deformity and replace in situ fusion. This was associated with high pseudarthrosis rates, need for postoperative immobilization, and flattening of sagittal spinal contour. Segmental correction techniques were introduced along with the Luque rods, Harri-Luque, and Wisconsin systems. Correction in both coronal and sagittal planes was not satisfactory and high rates of nonunion persisted until Cotrel and Dubousset introduced the concept of global spinal derotation. Development of pedicle screws provided a powerful tool to correct three-dimensional vertebral deformity and opened a new era in the treatment of scoliosis.

RESUMEN

Calcification of intervertebral disc in children is rare. It mostly affect lower cervical region and present with acute neck pain, torticolis, restriction of range of motion. Neurological deficit or dyspahagia are rare features. The presence of fever, leukocytosis and elevated erythrocyte sedimentation rate, gives impression of tuberculosis or other infections. This differentiation is important as the management of pediatric disc calcification is mostly conservative and prognosis is good.
