Irreducible rotary subluxation of the metacarpophalangeal joint (MCPJ) of the thumb is a rare entity. Open reduction is indicated when signs of irreducibility are seen on the radiographs. We present one such case caused by displacement of the sesamoid bone into the intercondylar notch of the first metacarpal bone. A 35-year-old woman sustained a twisting injury to her right thumb by pronating a...

Introduction: Failures in total wrist arthroplasty (TWA) can be most often attributed to three main factors: improper prosthesis centering, component loosening and soft tissue imbalance (1). Of these, one of the most often reported complications is metacarpal loosening with dorsal protrusion of the stem (2). Abnormal load transfer through the prosthesis is believed to contribute to component lo...

PURPOSE The motion path of the digits follows the path of an equiangular spiral in which a constant angle is formed by all radial vectors along the curve. This implies that the lengths of the metacarpals, proximal, middle, and distal phalanges approximate a Fibonacci sequence in which the ratio of any 2 consecutive numbers approaches the number 1.61803 (phi). This study tested the hypothesis th...

Objective- To measure statistically bone cortex to diameter  (C/D) ratio in metocarpo/metatarsal and proximal phalanges in camel. This ratio may be used in diagnosing possible metabolic and nutritional diseases in camel. Design- Experimental study. Animals- Twelve camel limbs (6 fore limbs & 6 hind limbs)      Procedures- This study was conducted on dorsopalmar/dorsoplantar radiographs of t...
