The so-called "functional position" of the hand for immobilization of an injured hand or finger may in many cases lead to stiffness of the finger joints by shrinkage of the joint capsule and -ligaments. This process can be minimized by immobilization of the small finger joints in a position where the most important ligament structures are under maximum tension. Basically this is the intrinsic-plus-position for the long fingers and palmar abduction and extension of the thumb. Immobilization in this so-called protective position of the hand minimizes immobilization damages of the small finger joints. The underlying basic principles of the anatomy are explained.

Exploring the prevalence of gout among underrepresented low socioeconomic status type 2 diabetes populations.

Background: Underserved and underrepresented populations often lack access to affordable, quality healthcare, educational resources, and nutritious foods, all of which contribute to increased risk of Type 2 Diabetes and gout. Type 2 Diabetes is a condition characterized by the denaturation of the insulin receptors, due to chronically high blood glucose levels, leading to impaired regulation of blood sugar. Gout is a chronic inflammatory disease affecting joints in the lower limbs, marked by elevated serum urate levels and the accumulation of uric acid crystals in synovial fluid, causing painful flare-ups that significantly impact quality of life.

This study aimed to evaluate early clinical outcomes following treatment with K-wire or IM fixation.
Methods: A retrospective review of all proximal phalanx fractures treated surgically at a single center by multiple surgeons was performed from May 1, 2019 to March 1, 2024.

Free vascularized partial great toe is a composite tissue consisting of the osteo-onycho-cutaneous component with neurovascular pedicle and is used for reconstructing amputated fingers at different levels. The half-big-toe nail flap represents that while it provides a good match and functional results; it also conserves the donor foot by having all five toes intact. The aesthetic and functional aspects of the amputated thumbs and fingers can be worked upon and significantly improved.
