BACKGROUND The purpose of this study was to present a novel surgical technique using an on-top osteotomy and to assess the clinical and radiographic outcomes for the triphalangeal Wassel type VI thumb duplication patients. METHODS The surgical technique involves ablation of the radial thumb at distal one-third of the metacarpal, corresponding metacarpal osteotomy of the ulnar thumb, with amal...

Purpose. We have observed worsening thumb pain following carpal tunnel release (CTR) in some patients. Our purpose was to determine the effect of open CTR on thumb carpometacarpal (CMC) biomechanics. Methods. Five fresh-frozen cadaver arms with intact soft tissues were used. Each specimen was secured to a jig which fixed the forearm at 45° supination, and the wrist at 20° dorsiflexion, with thu...

Background: Metacarpal fractures are among the most common fractures. The majority of metacarpal shaft fractures can be treated conservatively. There are numerous indications for operative treatment and various fixation techniques. The purpose of this prospective study was to assess the surgical and clinical outcomes of metacarpal shaft fractures using intramedullary fixation by K-wire (Kirschn...

There are numerous treatment algorithms that have been developed to treat thumb carpometacarpal (CMC) arthritis. A newer treatment option for these patients is CMC stabilization using suture button suspensionplasty. The authors of this case report have extensive experience with the suture-button suspensionplasty using the Mini TightRope CMC technique (Arthrex). We present a novel usage of the s...

The distribution pattern of collagen fibril diameter in the equine superficial digital flexor tendon (SDFT) is known to differ in central and peripheral areas of some regions. This study reports the essence of collagen fibril differences among different regions of the equine SDFT by transmission electron microscopic (TEM) and high-voltage electron microscopic observations and biochemical analys...

INTRODUCTION The objective of this study was to assess three-dimensional bone geometry and density at the epiphysis and shaft of the third meta-carpal bone of rheumatoid arthritis (RA) patients in comparison to healthy controls with the novel method of peripheral quantitative computed tomography (pQCT). METHODS PQCT scans were performed in 50 female RA patients and 100 healthy female controls...

Metacarpal shaft fractures tend to shorten and angulate. This tendency is accentuated with the fracture of multiple metacarpals. A variety of methods for treatment have been described. The purpose of this study is to present the results of treatment in patients with multiple metacarpal shaft fractures, treated in a minimally invasive manner, with an intramedullary rod device.

Metacarpal and metatarsal fractures are common injuries in small animals. They account for 8.1% and 3.3% of all fractures in dogs and cats respectively. This article will discuss the management options available including both surgical and conservative options of metacarpal and metatarsal fractures and the treatment options available. Surgical options discussed include bone plating, dowel pinni...
