Tibialis anterior tendon transfer using bone anchor for dynamic supination in congenital talipes equinovarus.

Tibialis anterior tendon transfer (TATT) is a recognised procedure for the treatment of recurrent congenital talipes equinovarus. The most common technique in use requires three skin incisions and breaching of the plantar tissues, risking pressure areas and damage to neurovascular structures. There have been no studies showing the clinical results of the use of a bone anchor to secure the tendon without drilling through the lateral cuneiform. This study presents the largest series of outcomes for such a procedure. Retrospective case series. Electronic records for all children under 18 undergoing TATT with anchor fixation included. Outcomes recorded were a failure of the tendon transfer and complications. Seventy-seven feet were identified in 61 children with a male-to-female ratio of 2.5:1, the average age at surgery of 5.6 years, and an average follow-up of 4.4 years. There were no cases of pullout of the anchor. Seventy-six cases (98.7%) had no recurrence of dynamic supination on follow-up. No revision surgery was required. Consistently reliable, reproducible and safe fixation of the tibialis anterior tendon in TATT can be achieved using a bone anchor for the treatment of dynamic supination in children with clubfeet following correction using the Ponseti method and is a quick and straightforward alternative method to traditional techniques.

CT estimation of glenoid bone loss in anterior glenohumeral instability : a systematic review of existing techniques.

AIMS: Recurrent dislocation is both a cause and consequence of glenoid bone loss, and the extent of the bony defect is an indicator guiding operative intervention. Literature suggests that loss greater than 25% requires glenoid reconstruction. Measuring bone loss is controversial; studies use different methods to determine this, with no clear evidence of reproducibility. A systematic review was performed to identify existing CT-based methods of quantifying glenoid bone loss and establish their reliability and reproducibility. METHODS: A Preferred Reporting Items for Systematic reviews and Meta-Analyses-compliant systematic review of conventional and grey literature was performed. RESULTS: A total of 25 studies were initially eligible. Following screening, nine papers were included for review. Main themes identified compared 2D and 3D imaging, as well as linear- compared with area-based techniques. Heterogenous data were acquired, and therefore no meta-analysis was performed. CONCLUSION: No ideal CT-based method is demonstrated in the current literature, however evidence suggests that surface area methods are more reproducible and lead to fewer over-estimations of bone loss, provided the views used are standardized. A prospective imaging trial is required to provide a more definitive answer to this research question. Cite this article: Bone Jt Open 2022;3(2):114-122.

Macrophage activation syndrome or septic arthritis: a case of mistaken identity.

We present an interesting case of macrophage activation syndrome in a 2-year-old, with no previous rheumatological diagnoses, incorrectly diagnosed with septic arthritis, to highlight the diagnostic difficulties, especially in small hospital units. We aim to present the similarities between the two conditions and to summarize the clinical, radiological and epidemiological features of macrophage activation syndrome, an underdiagnosed condition. A review of the current literature was performed, and a diagnostic algorithm was created. No current set treatment regimen exists, but current recommendations have been included. We have demonstrated the pitfalls in diagnosis and the importance of immediate treatment in optimizing prognosis.
