PurposeHigh rates of mechanical failure have been reported in type III acetabular defects. Recently porous trabecular metal augments have been introduced with, excellent biomechanical characteristics and biocompatibility, allowing early stability and greater bone ingrowth. The aim of the study was to assess the short term clinical and radiological outcome of the trabecular metal augments.Materials and MethodsWe performed, 22 revision total hip arthroplasties (THA) and 6 primary THA (total 28) using trabecular metal augments to reconstruct acetabular defect between 2011 to 2015. Among 28 patients, 18 were males, 10 females. Mean age of patients was 61.21 years. Paprosky classification for acetabular bone defects was used. Eighteen cases were classified as grade 3 A and 10 cases as grade 3B. Hip center was calculated in each case preoperatively and compared postoperatively to check whether it has been brought down. Clinical outcome assessed using Harris hip score (HHS) and radiological outcomes as osteolysis in acetabular zones and osseointegration, according to Moore's criteria.ResultsHHS improved from 58.00 to 86.20. Centre of rotation of hip joint corrected from 38.90 mm preoperatively to 23.85 mm postoperatively above the interteardrop line. Among 28 patients, 18 patients had three or more signs of osseointegration (Moore's criteria), during final follow up and 10 had one/two signs. No radiolucency, osteolysis, or loosening found during follow up radiographic examination.ConclusionOur study showed that trabecular metal augments were highly satisfactory in short term. However, long term study is required for better evaluation.
A case demonstrating a combination of ossified spinal arachnoid and syringomyelia is reported. A plea is made for denoting the condition as "ossification of the spinal arachnoid" rather than "spinal arachnoiditis ossificans".
Aim:To study the functional and radiological outcomes in cases managed conservatively for single-level traumatic thoracolumbar spine fractures without neurological deficit.Materials and Methods:In this prospective study design, thirty patients who presented to tertiary care hospital and diagnosed with posttraumatic thoracolumbar vertebral fracture without any neurodeficit were recruited. All the patients were managed conservatively as per the protocol which included bed rest, spinal braces, and physiotherapy. Adequate analgesia was given wherever necessary. The patients were followed at regular intervals up to a maximum of 2 years. Clinically visual analog scale (VAS) score and Roland Morris Disability Questionnaire (RMDQ)-24 were assessed and radiologically local vertebral kyphosis, scoliosis, and loss of body height were noted at each follow-up.Results:The data was statistically analyzed and the results were as follows. Thoracolumbar fractures were more in young adults (<26 years) and more so among the males (80% cases). The most common fracture type in our study was compression fracture. The most common site involved in our study was L1 vertebra (36.7%). There was a significant decrease of VAS score (pain score) in 79% cases with the maximum decrease in type A1 fracture. The mean RMDQ-4 score in our study was 5.53. The overall progression of kyphosis was 1.9°. There was no relation found between the kyphotic deformity and the clinical outcomes (VAS and RMDQ-24 scores). Canal size changes were found to be insignificant at the end of 2 years compared to baseline.Conclusion:Study showed favorable outcomes in terms of return to daily activities, making it a good option in managing Type A1 dorsolumbar fractures. Though there was a progression of kyphosis but no neurological deficit was seen.
Introduction: Recruitment of patients to participate in randomized control trials (RCT) is a challenging task, especially for trauma trials in which the identification and recruitment are time-limited. Multiple strategies have been tried to improve the participation of doctors and the recruitment of patients. The aim was to study the effect of a trainee principal investigator (TPI) on the efficacy of recruitment for a multicenter hip fracture RCT.Methods: A retrospective study comparing the number of junior doctors participating in the WHiTE 8 COPAL RCT and patients recruited before and after the introduction of formal TPI role at a major trauma center in the UK. Data was collected for nine months "before" (Nov 2018-July 2019) and six months "after" (Sept 2019-Feb 2020) the role of TPI was assigned.Results: From November 2018 to February 2020, a total of 292 patients were eligible for recruitment into this trial, out of which 196 (67.12 %) were successfully recruited. Excluding the research team, there were seven junior doctors actively recruiting in the "before period" in comparison with 10 in the "after period." Significantly more patients were recruited by junior doctors after a TPI was assigned. Overall, more percentage of eligible patients were recruited into the trial after a TPI was assigned, and this was statistically significant.
Conclusion:The allocation of a formal TPI significantly improved the recruitment of patients in a national RCT. TPI can work alongside the principal investigator and research team to be a valuable link person coordinating and engaging local trainees to take part in trials.
Pseudoaneurysm following percutaneous tendoachilles (TA) tenotomy is a rare complication found in children with congenital talipes equinovarus (CTEV). It is postulated that associated aberrant vascular anatomy in combination with CTEV may be the underlying aetiology. In this case report, we describe a case of a toddler who developed bilateral pseudoaneurysms following percutaneous tendoachilles tenotomy and explore the management and outcome in relation to this. Based on this case report and a review of the literature, the consistent clinical findings of swelling and/or discolouration due to pseudoaneurysm occur at three weeks post-tenotomy, and should raise suspicion for the diagnosis. Furthermore to the best of our knowledge, this is the first case report of bilateral pseudoaneurysms in the same setting, and we propose the possibility of an aberrant vessel arising from the peroneal artery that may be prone to injury.
Ganglion cysts of the psoas tendon are uncommon and rarely reported in the literature. Often they remain asymptomatic and are found incidentally or can be a cause of atypical groin/hip pain. We present a rare case of ganglion cyst in a child arising from the psoas tendon, causing symptomatic hip pain, which failed non-surgical treatment and eventually successfully treated with surgical excision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
