Treatment of fractures of the proximal phalanx and metacarpals is based on the presentation of the fracture, degree of displacement, and difficulty in maintaining fracture reduction. A wide array of treatment options exists for the variation in fracture patterns observed. Inherently stable fractures do not require surgical treatment; all other fractures should be considered for additional stabi...

A variety of fractures occur at the base of the first metacarpal bone, the best known being that described by Bennett in 1882. A group of more comminuted fractures also involving the carpo-metacarpal joint were later described by Rolando (1910). Transverse fractures at the lower end of the metacarpal bone were mentioned by Roberts (1938) in a review of all fractures occurring in the hand. Much ...

BACKGROUND Previous research has revealed that the ratios of the lengths of various pairs of human fingers differ in males and females. METHOD In an attempt to determine whether parallel sex differences also exist in the relative lengths of human metacarpals and metatarsals, the lengths of the metapodials for both hands and both feet were measured in a collection of human skeletons. For each ...

The capitate is often considered the "keystone" of the carpus, not simply because of its central and prominent position in the wrist, but also because of its mechanical interactions with neighboring bones. The purpose of this study was to determine in vivo three-dimensional capitate kinematics. Twenty uninjured wrists were investigated using a recently developed, non-invasive markerless bone re...

INTRODUCTION Aneurysmal bone cyst is a rare, rapidly growing, and destructive benign bone tumor that rarely involves the bones of the hand. Various treatment options for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. CASE REPORT A six year old boy presented with a history of pain and local swelling over his third metacarpal of fi...

Bioabsorbable implants offer an attractive alternative to metallic implants to stabilize small bone fractures in the hand. Self-reinforced bioabsorbable miniplating for metacarpal fractures was studied in bones from cadavers and compared with standard metallic fixation methods. One hundred twelve fresh-frozen metacarpals from humans had three-point bending and torsional loading after transverse...

The fibrous components of the metacarpophalangeal (MP) joint including the palmar plate, the collateral ligament and the dorsal plate were studied with particular attention paid to the fibrous structure of the fibrous tendon sheath and the deep transverse metacarpal ligament. The tough fibrillar structure around the MP joint, especially the force nucleus, consisted of three types of mixed fiber...

We explored the value of the metacarpal bone plane in screening for serious fetal forearm and hand deformities, excluding simple polydactyly and dactylion deformity, by ultrasonographic examination. Observed the second to fifth metacarpal bone plane of fetuses in 20,139 pregnant women at a gestational age of 16 to 30 weeks in The International Peace Maternity &Child Health Hospital of China Wel...

OBJECTIVE Successful reconstruction of the metacarpal hand requires thorough evaluation and careful surgical planning. Effective transplantation involves 3 main considerations: residual hand function, functional needs and desires of the patient, and optimal surgical management to maximize outcome and minimize patient morbidity. METHODS The following is a clinical example of the metacarpal han...

INTRODUCTION Simple bone cyst or unicameral bone cyst (UBC) are benign cystic lesions commonly found in femur and humerus. However hand is a very rare site of occurrence. Treatment described for UBC of hand commonly involves curettage and bone grafting. CASE REPORT A 7 year old right hand dominant girl presented to us with chief complaints of pain and swelling in right 4th metacarpal since 2 ...
