Case: Infantile Blount disease results from deceleration of growth by the proximal posteromedial tibial physis causing tibia vara. In advanced disease stages, surgical treatment is indicated. Owing to the young age and advanced Langenskiöld stage in this patient, a novel technique was performed combining lateral proximal physeal tethering with medial hemiplateau elevation osteotomy to correct the articular surface and unload the medial proximal tibial physis.
Conclusion: Together, these procedures allow for correction of alignment while preserving growth potential. This technique was successful in correcting tibia vara due to infantile Blount disease while allowing continued growth in a 5-year-old patient.

: Infantile tibia vara (ITV) is a rare proximal tibia deformity in infancy, leading to progressive knee varus. High tibial osteotomy is commonly practiced but has high recurrence rates. This study analyzed factors affecting treatment failure and recurrence in children undergoing opening-wedge high tibial osteotomy (OWHTO) for ITV.

Article Synopsis
- Blount disease causes deformities in the knees, including bowing and misalignment, and its treatment remains debated despite various approaches.
- A case of a nine-year-old girl with significant knee deformities was successfully treated using the Ilizarov external fixator, resulting in noticeable clinical improvement.
- The Ilizarov frame is recommended for its ability to provide precise corrections while minimizing risks compared to alternative techniques like physeal distraction, leading to positive treatment outcomes without significant complications.
Pediatric hypophosphatasia: avoid diagnosis missteps!

Article Synopsis
- Hypophosphatasia (HPP) is a genetic disorder that affects bones and teeth because a specific gene called ALPL doesn’t work right.
- When ALPL is mutated, it leads to a buildup of substances that can weaken bones and teeth, causing issues like weak muscles.
- Diagnosing HPP can be tricky because it has different forms and symptoms, but testing the ALPL gene and using special treatments can help manage it better.
Tension-Band Plating for Infantile Blount Disease: Efficacy and Outcomes Comprehensive Review.

Article Synopsis
- Infantile Blount disease (IBD) is a knee deformity that can cause issues like abnormal walking and pain if not treated, with traditional treatments including bracing and tibial osteotomy, while guided growth with tension-band plating (TBP) is becoming more common.
- A systematic review identified seven relevant studies, involving 92 limbs affected by IBD, focusing on TBP treatment effectiveness, correction rates, and complications over follow-ups ranging from four months to eight years.
- TBP showed an average deformity correction of about 79%, with reported complications including infection and hardware failure, and a significant reoperation rate of nearly 30%; however, more research is needed to explore risk factors and further differentiate treatment efficacy among
