Causes of late-presenting developmental dislocation of the hip beyond 12 months of age: A pilot study.

Background & objectives: Developmental dysplasia of the hip (DDH), when detected early, can usually be managed effectively by simple methods. A delayed diagnosis often makes it a complex condition to treat. Late presentation of DDH is fairly common in developing countries, and there is scarcity of literature regarding the epidemiology and reason for late presentation. Through this study, we attempted to identify the reasons for late presentation of DDH in children more than 12 months of age. Methods: Fifty four children with typical DDH and frank dislocation of hip in whom treatment was delayed for 12 months or more were included. Parents were interviewed with a pre-structured questionnaire and data were collected for analysis with Microsoft Excel 2016 and SPSS version 26. Results: Diagnostic delay was the most common reason for late presentation and was observed in 52 children (96.2%). The mean age at diagnosis was 24.7 months. The mean age at treatment was 37.3 months with a mean delay of 12.5 months from diagnosis and 22.1 months from initial suspicion. Physician-related factors contributed 55.3 per cent, while family and social issues accounted for 44.7 per cent of overall reasons for diagnostic and treatment delays. Interpretation & conclusions: Late presentation of DDH in walking age is common. Physician- and family-related factors accounted for most of these cases. Failure or inadequate hip screening at birth by the attending physician is a common reason for late diagnosis. The family members were unaware about the disorder and developed suspicion once child started walking with an abnormal gait.

Role of percutaneous transpedicular biopsy in diagnosis of spinal tuberculosis and its correlation with the clinico-radiological features.

INTRODUCTION: Tuberculosis (TB) has long been an important cause of destructive lesions of spine in India. However the scenario is fast changing with atypical presentations and increasing reports of non-tubercular conditions. This poses a great diagnostic dilemma. AIM: The present study is aimed at evaluating the diagnostic efficacy of percutaneous transpedicular needle biopsy and the correlation of the histology with clinico-radiological features. METHODS: Forty-one patients diagnosed of TB spine by magnetic resonance imaging (MRI) were revaluated of their clinical presentations, radiological and MRI features and underwent transpedicular needle biopsy under fluoroscopic guidance. Quality of the sample and radiological/MRI features between the tubercular and non-tubercular lesions were studied. RESULTS: A good sample obtained in 92.7% patients. Of these 28 patients had TB, 3 non-specific inflammatory lesion and 7 with other non-tubercular conditions (3 pyogenic, 3 metastasis, 1 multiple myeloma). Statistically there is no significant difference among the TB and non-TB groups in terms of vertebral involvement and MRI features. However risk of presentation with cord compression, cord changes and neurodeficit are higher with TB spine. CONCLUSION: It is very difficult to differentiate between tubercular and non-tubercular pathology of spine on the basis of most of the clinical and MRI features. It is more difficult in early cases without any neurodeficit. Thus histopathological confirmation is must for further management and percutaneous needle biopsy is the best option considering the simplicity and minimally invasive nature of the procedure.

Significance of Vertebral Endplate Failure in Symptomatic Lumbar Disc Herniation.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: Endplate lesions though have been implicated in the genesis of lumbar disc herniation (LDH), very little is known regarding their clinical course. Thus, the present study is aimed to investigate the incidence and types of endplate failure (EPF) in LDH and its correlation with the clinical symptoms and prognosis. METHODS: Clinical and magnetic resonance imaging (MRI) features of 66 patients with isolated single level LDH were studied. Three-dimensional fast spoiled gradient (3D FSPGR) MRI and computed tomography scans were used to identify the bony and cartilaginous EPF. Twenty-five patients were operated on and 41 patients were treated conservatively. Changes in the pain score, function and neurology were noted at 3, 6, 12, 24, and 36 weeks. RESULTS: Endplate lesions were observed in 64 patients (96.9%), including bony endplate failure (bony failure) in 47 patients (71.2%) and isolated cartilaginous endplate lesions in 17 patients (25.7%). Bony failure group had similar pain and functional scores but more severe neurological deficit at the initial evaluation. Clinical parameters improved in all groups, but the recovery was lesser in conservatively treated bony failure patients. CONCLUSION: Endplate lesions are commonly associated with symptomatic LDH. Presence of bony failure can increase neurological deficit and reduce the chance of recovery with conservative management. The 3D FSPGR sequence of MRI can be successfully used for detection of the endplate lesions in the herniated disc.

Patellar ligament rupture during total knee arthroplasty in an ochronotic patient.

Ochronotic arthropathy mainly involves the spine and large joints. Along with blackening of the joint, degeneration rapidly progresses mostly in the knee, resulting in symptoms by the 4th or 5th decade. As the role of medical treatment and joint conservation surgeries are limited in the early stages, joint replacement is the only effective option in one third of patients. We present a case of the unique complication of patellar ligament rupture during total knee replacement (TKR) of an ochronotic joint. A 51-year-old male presented with bilateral severe tricompartmental osteoarthritis with varus deformities and restriction of motion. Bilateral TKR was performed. At the 28-month follow-up, the patient was walking pain free with acceptable position of implants in radiographs. To our knowledge this is the first report of rupture of the patellar ligament during TKR of an ochronotic joint. We propose appropriate preoperative preparation and greater care in the handling of the tendon during TKR of an ochronotic joint in order to avoid complication.

Pediatric cervical disc calcification simulating tubercular spondylitis - A case report.

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.
