ABSTRACT
Aim The aim of this study was to undertake a clinical study to evaluate the outcomes of transforaminal endoscopic discectomy under local anesthesia and to study the complication rate. Study Design It is a prospective study. Methods We prospectively analyzed outcomes of 60 patients with a single-level lumbar disc prolapse in rural India from December 2018 to April 2020 who underwent endoscopic discectomy under local anesthesia. Follow-up was done using the visual analogue score (VAS) and Oswestry Disability Index (ODI) scoring systems with a minimum follow-up up to 1 year postoperatively. Results In our study of 60 patients, there was 38 cases of L4-L5 disc pathology, 13 L5-S1 discs, and 9 L3-L4 discs. Our study showed a significant clinical reduction in mean VAS score that was 7.07/10 preoperatively and reduced to 3.88/10 at the third month and 3.64/10 at 1 year of follow-up ( p -value < 0.05) showing clinical significance. The ODI scoring done preoperatively was an average mean of 57.37% pointing to how crippled the patients were with lumbar disc prolapse and showed a significant reduction to 29.32% postoperatively at 1 year ( p -value < 0.05) showing clinical significance. This reduction in ODI directly corelates to how almost all patients returned to normal life coping to all activities and were completely pain free at 1 year of follow-up. Conclusion Endoscopic spine surgery in lumbar disc prolapse is highly effective and can deliver a good functional outcome if done with correct preoperative planning and approach.
ABSTRACT
Objectives: Our purpose was to evaluate the clinical results of PCL tibial avulsion fracture fixation performed with 4 mm cancellous screws using a dual posteromedial (PM) portal technique. Methods: In a prospective study, we followed 12 patients submitted to PCL tibial insertion avulsion arthroscopic fixation using dual PM portals with cancellous screws from March 2014 to Jan 2020. The proximal higher PM portal served as an instrument portal and provided an optimal trajectory for arthroscopic screw fixation of larger PCL avulsion fractures. The lower PM portal was used as a viewing portal. Results: Significant improvements were found between the preoperative and postoperative mean Lysholm scores at six months. The preoperative IKDC score mean of 10.13 increased to 89.3 at the end of six months. Minor adverse results with this technique were: grade I on posterior sag in five knees (41.6%), temporary stiffness in two cases (16.7 %), delayed union in one patient (8.3 %), and difficulty squatting at the end of six months in one patient (8.3%). Temporary extension lag was present in two individuals (16.7%), and fixed subtle flexion deficit of 3-5 degrees occurred in one individual (8.3 %). Conclusion: The outcomes obtained with the proposed technique were similar to those obtained with open techniques, although mild flexion deficits and discreet posterior sag may be present in a significant number of cases. Level of Evidence II; Prospective Cohort Study .
Objetivos: O objetivo foi avaliar os resultados clínicos da fixação da fratura da avulsão tibial PCL realizada com parafusos esponjosos de 4 mm, utilizando uma técnica de portal postero-medial (PM) duplo. Métodos: Em um estudo prospectivo, acompanhamos 12 pacientes submetidos à fixação da avulsão tibial de inserção PCL por via artroscópica utilizando portais duplos PM com parafusos esponjosos de março de 2014 a janeiro de 2020. O portal PM proximal superior serviu como um portal de instrumentos e forneceu uma trajetória ideal para a fixação artroscópica com parafusos de fixação de fraturas avulsas PCL maiores. O portal PM inferior foi usado como um portal de visualização. Resultados: Foram encontradas melhorias significativas entre o pré-operatório e o pós-operatório, com pontuação média de Lysholm aos seis meses. A pontuação média do IKDC pré-operatório de 10,13 aumentou para 89,3 no final dos seis meses. Os resultados adversos menores com esta técnica foram: grau I na flacidez posterior de cinco joelhos (41,6%), rigidez temporária em dois casos (16,7%), união tardia em um paciente (8,3%) e dificuldade de agachamento ao final de seis meses em um paciente (8,3%). O atraso temporário da extensão estava presente em dois indivíduos (16,7%) e o déficit de flexão sutil fixo de 3-5 graus ocorreu em um indivíduo (8,3%). Conclusão: Os resultados obtidos com a técnica proposta foram similares aos obtidos com técnicas abertas, embora déficits leves de flexão e discreta flacidez posterior possam estar presentes em um número significativo de casos. Nível de Evidência II; Estudo de Coorte Prospectivo.

ABSTRACT
The posterior cruciate ligament surgery invariably demands adequate posterior compartment visualisation and instrumentation. The addition of posteromedial (PM) portal during posterior cruciate ligament (PCL) surgeries remains essential. The further addition of one more proximal posteromedial (PM) portal further enhances the instrumentation including suture passage in the substance of PCL or screws insertion and more so obviates the need for trans-septal and posterolateral (PL) portals. This additional PM portal is created in the safe zone under direct visualisation utilising outside-in technique and is spaced to prevent crowding of instrument with arthroscope. The proximal higher PM portal serves as instrument portal and provides optimal trajectory for even arthroscopic screw fixation of PCL avulsion fractures.
ABSTRACT
Introduction: Primary subacute pyogenic osteomyelitis, or Brodie's abscess was initially documented by Sir Benjamin Brodie in 1832. We present a case report with a 6-months follow-up period, demonstrating the successful diagnosis and surgical treatment of a focal lesion of the proximal metaphysis of the right humerus in a 21-years-old female. The pathology of hematologic osteomyelitis and its role in the development of a subacute abscess along with a review of literature and an in detail description of the pathogenesis of Brodie's abscess is discussed and submitted. Case Presentation: A 21- years -old healthy female with a history of fall sustaining injury to the right shoulder one 1 year back followed by which she presented to the outpatient clinic with a swelling over her right shoulder. The patient was managed conservatively with analgesics and was relieved of pain over a course of one 1 week of medications, the patient now presents with pain and swelling in the right shoulder joint on and off since the episode of fall one 1 year back, which had increased over a period of past one 1 week. A week before the most recent presentation she started experiencing some discomfort and pain in her right shoulder. No recent trauma was reported. A mild swelling appeared over the proximal part of the humerus. There were no constitutional symptoms of fever or any illness reported. On examination, there was noted a painful restriction of ROM at the right shoulder joint with no rotator cuff injury. Laboratory investigations were suggestive of raised inflammatory markers. Radiograph of the right shoulder taken in the true antero-posterior view with the shoulder in the neutral rotation was suggestive of an oval lucency with surrounding sclerosis in the proximal metaphyseal region of the humerus. Magnetic resonance imaging MRI of the right shoulder joint showed features consistent with Brodie's abscess in the proximal metaphyseal region of the humerus. Surgical debridement of the abscess was planned. The right shoulder of the patient was immobilized by a universal shoulder immobilizer for 3 days post -operatively and then Pphysiotherapy for shoulder range of movements was started. Infectious parameters decreased and there were no complications in the postoperative period. Regular follow follow-up for two 2 weeks showed clinical improvement. At 6 months follow- up, the patient had made full recovery with radiographic improvement. Conclusion: Brodie's abscess was first described by Sir Benjamin Brodie in 1832. Primary hematogenous subacute osteomyelitis is rarely seen in the proximal metaphysis of the humerus. With appropriate surgical debridement and aggressive antibiotic cover, a near 100% success rate is observed in the treatment of Brodie's abscess with no residual deformities in the affected bones or restrictions in the range of movements in the neighboring joints.
