Treatment of nondisplaced scaphoid waist fractures has evolved from conventional cast immobilization to percutaneous screw insertion. This study assessed clinical and radiologic outcomes of volar percutaneous screw fixation for 15 type B2 scaphoid fractures (according to the Herbert and Fisher classification). All patients were followed for an average of 33 months (range, 6-50 months). All frac...

Devastating perilunate injuries are rare, compromising of less than 10% of wrist injuries. We report a 19-year-old worker man who presented with left wrist pain and swelling after falling from a height. Not only the lunate was seen in middle third of forearm, but also proximal part of the scaphoid was in distal forearm. Open reduction and internal fixation was done via volar approach. He came b...

The scaphoid is the most commonly fractured carpal bone, with frequent complications that are predisposed by its anatomical location, anatomical configuration (shape and length), and vascular supply. The most common mechanism of injury is a fall onto an outstretched hand. Imaging plays a significant role in the initial evaluation and treatment of scaphoid fractures and their complications. Radi...

Primary bone healing fails to occur in 5-15 % of scaphoid bones that undergo fracture fixation. Untreated, occult fractures result in nonunion up to 12 % of the time. Conventional bone grafting is the accepted management in the treatment algorithm of scaphoid nonunion if the proximal pole is vascularized. Osteonecrosis of the proximal scaphoid pole intuitively suggests a need for transfer of th...

BACKGROUND Surgically, it is difficult to achieve union of a scaphoid nonunion that is associated with osteonecrosis of the proximal pole, and those with carpal collapse are especially difficult to treat. A variety of vascularized bone grafts can be used. The purpose of this study was to compare the effectiveness of two types of vascularized bone graft -- a distal radial pedicle graft and a fre...

BACKGROUND Delays in diagnosis and inadequate treatment of acute scaphoid fractures can lead to non-unions, presenting surgeons with unique challenges regarding optimal management. OBJECTIVES To evaluate the clinical and radiographic outcome of scaphoid non-unions treated with percutaneous screw fixation. METHODS The study group comprised 12 patients with scaphoid non-unions of an average d...

Bone fractures have a high degree of severity. This is usually result the physical trauma diseases that affect bone tissues, such as osteoporosis. Due to its highly vascular nature, in constant state remodeling. Although those younger ages possess bones with regenerative potential, impact disrupted vasculature can severely recovery process and cause osteonecrosis. commonly seen neck femur, scap...
