Management of thumb hypoplasia in Vietnam: Challenges in a developing country and future directions.

Thumb hypoplasia, a congenital malformation characterized by an underdeveloped or absent thumb, presents significant functional and aesthetic challenges. In Vietnam, a low-middle income developing country, the management of thumb hypoplasia is shaped by limited resources, geographic disparities, and reliance on international collaborations. This article reviews the current state of diagnosis, surgical treatment, and rehabilitation of thumb hypoplasia in Vietnam, with a focus on the unique challenges faced by healthcare providers in resource-constrained settings. The role of international experts, including Dr. Terry Light, Dr. Takehiko Takagi, Dr. Alain Gilbert, and Dr. Philippe Valenti, is emphasized for their contributions in shaping advanced surgical techniques and mentoring local surgeons. We also discuss the critical involvement of the Vietnam Pediatric Orthopaedic Association (VPOA) in promoting pediatric orthopedic care. Future recommendations include expanding access to specialized care, improving surgical training, decentralizing services to rural areas, and encouraging the publication of local research to foster global collaboration. By addressing these areas, Vietnam can continue to enhance outcomes for children affected by thumb hypoplasia.
