A Rare Case of Hallux Saltans Treated using Ultrasound-guided Intralesional Steroid Injection: A Case Report.

Introduction: Stenosing tenosynovitis is a condition characterized by the inflammation and constriction of the tendons within a fibro-osseous tunnel. Case Report: We present a case of a 38-year-old man who presented with hallux saltans, a rare manifestation of this condition which was successfully treated with intralesional steroid injection. The patient experienced significant relief from pain and improved function following the procedure. Conclusion: This case highlights the importance of considering stenosing tenosynovitis as a potential cause of hallux saltans and the efficacy of non-surgical interventions in its management.

Arthroscopic management of large subchondral talar cyst: a novel treatment strategy.

Subchondroplasty is a novel and minimally invasive technique used to treat large subchondral talar cysts. It avoids soft tissue scarring, the need for osteotomies, bone grafting and its associated complications as seen with conventional approaches. Subchondroplasty involves arthroscopically approaching the cyst and injecting it with calcium phosphate paste injection, which undergoes an endothermic process and crystallizes in a manner that resembles cancellous bone to fill the defect. This case series presents two patients who underwent subchondroplasty: a 44-year-old female nurse with atraumatic right ankle pain of 2 years with a CT scan revealing a large subchondral cyst over the medial talar dome and a 55-year-old male chemical plant worker with left ankle pain following a biking accident 6 years ago whose CT scan too showed a large subchondral cyst in the medial talus. Both tolerated the surgery well, with significant reductions noted in MOXFQ scores at the 1-year follow-up.

Closed, Atraumatic, and Spontaneous Extensor Hallucis Longus Tendon Rupture Following Multiple Steroid Injections and Presence of Talonavicular Osteophyte Repaired using a Turndown Flap: A Case Report.

Introduction: We present a case of spontaneous rupture of the extensor hallucis longus (EHL) tendon with significantly retracted tendon edges in a patient who had received multiple steroid injections to an arthritic talonavicular joint repaired using novel turndown flap technique. Case Report: This case details a patient who came in with a history of spontaneous EHL tendon rupture on a background of chronic pain in the midfoot due to osteoarthritis with osteophytes at the talonavicular joint for which they had received multiple steroid injections in the past. A novel repair technique was employed which involved split lengthening the proximal segment of the ruptured EHL tendon and making a turndown flap of the same by rotating the lengthened segment 180°, bridging the tendon gap. The lengthened tendon is then sutured to the distal segment of the EHL to achieve a tension-free repair. This bypasses any use of bridging allografts and autografts/tendon transfer, removing complications commonly associated with them. Conclusion: This turndown flap technique is easy to perform, reduces surgical time, avoids complications associated with tendon grafting, and results in good functional outcomes for the patient.

Improvement in functional gait parameters following corrective thoracolumbar surgery in children affected by Mucopolysaccharidosis 1 (Hurler syndrome).

OBJECTIVE: Thoracolumbar kyphosis is a common indication for spinal surgery in children with Mucopolysaccharidosis. Functional outcome of spinal surgical intervention has never been published in patients with this rare disease. We present a cohort of patients with Mucopolysaccharidosis 1(Hurler syndrome) who underwent thoraco-lumbar spinal deformity correction and functional outcome assessed by pre-operative and post-operative gait analysis. This study represents the first attempt at presenting a functional assessment of surgical outcome in any Mucopolysaccharidosis subtype. METHODS: A retrospective analysis of prospectively collected data was carried out from 11 children diagnosed with this subtype of Mucopolysaccharidosis. All patients underwent thoracolumbar kyphosis correction between the years 2013 to 2016. Gait assessment was performed using GAITRite™ electronic walkway pre-operatively and post-operatively within 9 to 24 months from the index surgery. Walking distance, cadence and gait velocity were the three spatio-temporal parameters analysed. Wilcoxon signed rank test was used to analyse the data and P-Value ≤0.05 was deemed significant. RESULTS: There was a statistically significant improvement in walking distance in 9 out of 11 patient post-operatively with a mean increase of 232.06 cms (P = 0.05). There was marginal improvement in cadence by 6.33 steps/min post-operatively (P-value 0.79). Gait velocity also showed a marginal increase by 8.73 cms/sec post-operatively (P-value 0.32). CONCLUSION: The results of our study suggest that correction of thoracolumbar kyphosis in children with Mucopolysaccharidosis 1 resulted in a significant improvement of walking distance with a trend towards improved gait in the other parameters. Post-operative change in cadence was not statistically significant suggesting that physiological maturation of gait had minimal effect in the specified post-operative assessment timeframe. This study emphasizes that outcomes of spinal surgery in children with Mucopolysaccharidosis 1 should be determined by functional measures aiming to maintain or improve quality of life.

Heterotopic ossification following use of i-Factor for spinal fusion in Mucopolysaccharidosis 1: a case report.

Mucopolysaccharidosis is a rare group of genetic disorder which results in a complex of anomalies involving various systems. In Mucopolysaccharidosis 1 progressive thoracolumbar kyphosis is a common presentation which can result in instability and neurological deficit. Posterior spinal surgery is performed to correct deformity and obtain spinal fusion. Peptide enhanced bone graft substitute (i-FactorTM) is relatively a new component with proven efficacy to obtain early spinal fusion. An 8-year-old child with progressive high lumbar kyphosis due to Mucopolysaccharidosis 1 was admitted for Posterior spinal fusion with i-Factor bone graft substitute. Postoperatively patient had serous discharge from the wound which settled without intervention. A month after the surgery spinal radiographs revealed heterotopic ossification at the distal end of spinal construct in the paraspinal region. Patient remained asymptomatic and clinically well.

Unusual Presentation of a Primary Ewing's Sarcoma of the Spine with Paraplegia: A Case Report.

Ewing's sarcoma is a primary malignancy of the bone affecting individuals in the second decade of life. Primary sarcomas of the spine are rare and the occurrence of Primary Ewing's sarcoma in the spine is very rare. Ewing's sarcoma occurring in the spine is divided into two types, Ewing's sarcoma of sacral spine which are very aggressive with poor prognosis and Ewing's sarcoma of the non sacral spine which is an extremely rare occurrence. Patient may present with neurological deficit when the tumour extends into the spinal canal causing spinal cord compression. Magnetic resonance imaging (MRI) is very sensitive in diagnosing the tumour and defining the extent of the tumour. Here we report an 18-year-old boy who presented with back pain and complete paraplegia of two months duration. The MRI gave a differential diagnosis of infective pathology due to the fluid collection in the paraspinal region, followed by primary malignancy as the second diagnosis. Patient underwent posterior spinal decompression and stabilization, and intaoperatively there was significant collection of pus whose culture showed no growth. The histopathology and immunohistochemistry studies confirmed the diagnosis of Ewing's sarcoma and patient was started on combination chemotherapy and radiotherapy.
