RESUMEN

OBJECTIVE: To compare the effect of two different corticosteroid types in bilateral and symmetrical knee osteoarthritis (OA). METHODS: One hundred and twenty-six patients received injections of methylprednisolone acetate (MP) in one knee and triamcinolone hexacetonide (TH) in the contralateral knee. Patients were evaluated before injection and 2, 4, 8, 12, and 24 weeks after. RESULTS: Mean patient age was 68.5±9 years. Mean BMI was 26.3±2.6 kg/m2. At first admission, mean VAS score was 7.7±1.3 for the right side and 7.5±1.5 for the left side, and mean WOMAC score was 67.6±14.4. After bilateral intra-articular injection, VAS scores for both knees and WOMAC scores decreased significantly when initial scores were compared with 2, 4, 8, 12, and 24 weeks after injection (p<0.05). A statistically significant change was seen over time when VAS and WOMAC scores for 2, 4, 8, 12, and 24 weeks post-injection were compared to each other (p<0.05). No significant difference was seen between knee sides (p>0.05). CONCLUSION: MP and TH have similar efficacy in relieving pain and improving function. The efficacy of intra-articular corticosteroid injection peaks 2 weeks after injection and the effect continues until the 24th week. Level of Evidence II, Comparative Prospective Study.

OBJETIVO: Comparar o efeito de dois tipos de corticosteroides em osteoartrite (OA) de joelho bilateral e simétrica. MÉTODOS: Cento e vinte e seis pacientes receberam injeções de acetato de metilprednisolona (MP) em um joelho e de triancinolona hexacetonida (TH) no joelho contralateral. Os pacientes foram avaliados antes da injeção e 2, 4, 8, 12 e 24 semanas depois. RESULTADOS: A média de idade dos pacientes foi 68,5 ± 9 anos. O IMC médio foi 26,3 ± 2,6 kg/m2. Na primeira internação, o escore médio da EVA foi 7,7 ± 1,3 para o lado direito e 7,5 ± 1,5 para o esquerdo e a média do escore WOMAC foi 67,6 ± 14,4. Depois da aplicação bilateral das injeções intra-articular, os escores da EVA e do WOMAC para ambos os joelhos diminuíram significantemente ao comparar os escores iniciais com os de 2, 4, 8, 12 e 24 semanas depois da injeção (p < 0,05). Constatou-se diferença estatisticamente significante no decorrer do tempo, quando os escores EVA e WOMAC às 2, 4, 8, 12 e 24 semanas depois da injeção foram comparados entre si (p < 0,05). Não houve diferença significante entre os lados direito e esquerdo (p > 0,05). CONCLUSÃO: MP e TH têm eficácia similar quanto ao alívio da dor e à melhora da função. A eficácia da injeção intra-articular de corticosteroides atinge o máximo duas semanas depois da aplicação e o efeito continua até a 24a semana.

RESUMEN

INTRODUCTION: Achondroplasia is the most common skeletal dysplasia with a rate of nearly 1/10,000. The development of lower extremity deformity is well documented, and various modes of correction have been reported. There are no reports on the use of growth modulation to correct angular deformity in achondroplasia. METHODS: Medical Records from 1985 to 2015 were reviewed for the diagnosis of achondroplasia and growth modulation procedures. Patients who had been treated for angular deformity of the legs by growth modulation were identified. A detailed analysis of their medical record and preoperative and final lower extremity radiographs was completed. RESULTS: Four patients underwent growth modulation procedures, all to correct existing varus deformity of the legs. Three of the 4 patients underwent bilateral distal femoral and proximal tibial growth modulation. The remaining patient underwent tibial correction only. Two of the 4 patients had a combined proximal fibular epiphysiodesis. All limbs had some improvement of alignment; however, 1 patient went on to bilateral osteotomies. Only 1 limb corrected to a neutral axis with growth modulation alone at last follow-up, initial implantation was done before 5 years of age. CONCLUSIONS: Growth modulation is an effective means for deformity correction in the setting of achondroplasia. However implantation may need to be done earlier than would be typical for patients without achondroplasia. Osteotomy may still be required after growth modulation for incomplete correction.

RESUMEN

BACKGROUND: Mobius syndrome is a rare syndrome that is known to be associated with a variety of orthopaedic conditions including scoliosis, clubfoot, transverse limb deficiencies, Poland syndrome, and a myriad of hand conditions. To date, no large series exist to characterize the orthopaedic manifestations of Mobius syndrome. METHODS: Medical records at a single tertiary pediatric institution were reviewed for all patients diagnosed with Mobius syndrome from January 1, 1980 to December 31, 2015. Records and radiographs were reviewed for associated orthopaedic conditions and their management. RESULTS: In total, 44 patients with Mobius syndrome were identified. Age at presentation ranged from 6 days to 14 years. When compared with the general population, patients with Mobius syndrome had an increased incidence of clubfoot (41%), Poland syndrome (20%), and scoliosis (14%). Clubfoot treated both before and after the institution of Ponseti casting had a high rate of requiring posteromedial release, with a significant rate of subsequent revision. Hip dysplasia was noted in 1 patient and required surgical correction. Other associated syndromes included arthrogryposis, Pierre Robin syndrome, and chromosome 10 defect. CONCLUSIONS: Mobius syndrome is accompanied by an increased rate of several orthopaedic problems; most notably clubfoot, scoliosis, and upper extremity differences that often require surgical treatment. The management of clubfoot in the setting of Mobius syndrome often requires surgical intervention due to failure of casting, and seems to have a higher rate of need for revision. Early involvement of orthopaedists in the care of patients with Mobius syndrome is often necessary. Orthopaedist should counsel families that treatment may be more complex than that of idiopathic disease. LEVEL OF EVIDENCE: Level IV-case series.

RESUMEN

INTRODUCTION: Perilunate injuries are rare entities which can be difficult to diagnose. Most common type is dorsal perilunate fracture dislocation (97%). The purpose of treatment is anatomic reduction and stable fixation. We aimed to present the radiologic and functional results of surgically treated dorsal perilunate fracture-dislocations and discuss the factors influencing the prognosis. METHODS: Between 2007 and 2013, 17 patients were operated for perilunate fracture-dislocations. The mechanism of injuries, soft tissue traumas, etiologic factors and stages according to Herzberg classification were determined. The MAYO wrist score was used for functional evaluation. Scapholunate distance and scapholunate angle were measured and, degenerative changes were investigated by comparing with contralateral side on plain x-ray images in terms of radiologic evaluation. RESULTS: Mean follow-up was 37,8 (range, 16-84) months. The average age at surgery was 35.1 (range, 18-51) years. Fifteen patients were male and two were female. Functional results were excellent in four (23.5%), good in two (11.8%), satisfactory in five (29.4%) and poor in six (35.3%) patients. Degenerative changes were determined in radiocarpal and mid-carpal joints of 14 wrists (82.4%). Scapholunate dissociation more than 2 mm was detected in three wrists. In four wrists osteochondral fragments were determined on the head of the capitate. Stage 2 lesions, delayed presentations, open fractures, scapholunate dissociations more than 2 mm had worse functional results. CONCLUSION: Despite anatomic reduction, ligamentous and chondral injuries that occured at the time of trauma may cause persistant wrist pain in patients who suffer perilunate fracture dislocation. Mechanism of injury, presence of soft tissue defects and the time between injury and treatment can affect clinical and radiologic results.

RESUMEN

INTRODUCTION: Ochronosis is a rare disorder which is defined as the deposition of metabolites of oxidation and polymerization of homogentisic acid, which have high affinity to collogen, in the connective tissues. It is a clinical condition characterized with ochronotic pigmentation of tissues, degenerative arthropathy of especially large joints and black discoloration of urine. In this paper we present a case of ochronosis diagnosed with biopsy and additional tests when a black discoloration of menisci and joint cartilage were detected during arthroscopic intervention for a degenerative meniscus tear. PRESENTATION OF CASE: A forty two year-old male patient was operated for lateral meniscus tear of his right knee. The arthroscopic examination of right knee revealed black colored synovial hypertrophy and torn lateral meniscus. Partial meniscectomy was performed. The diagnosis of ochronosis was made after histopathologic examination. DISCUSSION: Ochronotic pigment can accumulate in hyaline cartilage, tendon, skin, teeth, nail, sclera, tympanic membrane, heart valves, renal tubular cells, duramater, pancreas and walls of large arteries. In ochronosis the most frequently involved joints are knee and hip. In ochronotic arthropathy, articular cartilage become more sensitive to mechanical stresses. Our patient had meniscal tear, cartilage damage and black discoloration of synovial tissues and meniscus. CONCLUSION: Arthroscopy may be helpful in diagnosis of ochronotic arthropathy.
