SCAPHOID FRACTURES account for 71% of carpal bone fractures, and between 2% and 7% of all orthopaedic fractures (Nishihara 2000). This type of injury also accounts for one in every 10,000 attendances annually in UK emergency departments (EDs) (Tai and Ramachandran 2005). Between 5% and 12% of scaphoid fractures are related to other fractures (Malik et al 2010). The scaphoid is one of the eight ...

Avascular necrosis of the lunate, first described by Kienbock, can be treated either conservatively or by various surgical procedures. We compared the results of 18 conservatively treated patients, all of whom had stage-2 or stage-3 disease, with those of 15 who underwent a radial shortening procedure. We evaluated pain, range of movement, grip strength and functional disability, and determined...

Abrasive machining in general and grinding in particular are processes, which increase their importance with high demands on accuracy of surface finish. The chip thickness is an evaluating variable to describe the quality of ground surface as well as the performance of the overall grinding system. A significant characteristic that distinguishes ceramics from metals is their low fracture toughne...

Interface reliability issue has become a major concern in developing flip chip assembly. The CTE mismatch between different material layers may induce severe interface delamination reliability problem. In this study, multifunctional micro-moiré interferometry (MI) system was utilized to study the interfacial response of flip chip assembly under accelerated thermal cycling (ATC) in the temperatu...

RS Richards, JH Roth. Scaphoid fractures. Can J Plast Surg 1996;4(3):143-149. Scaphoid fractures are the most common carpal bone fractures and present physicians with many problems. The majority of such fractures (90%) will unite if properly treated; however a scaphoid fracture that goes on to nonunion affects a patient’s working capacity for a long period of time. This paper reviews the pathop...

The stability of the wrist during motion and interrelated motions depends on the capsuloligamentous integrity and the contact surface contours of the carpal bones [1]. Perilunate fracture dislocations (PLFD) are high-energy injuries, produced by wrist hyperextension. It can be palmar or dorsal. Palmar dislocation is extremely rare and result from a fall on the dorsum of the flexed wrist. This i...

Chondroma is the most common primary bone tumour of the hand, but carpal chondroma has, as far as we know, been reported only twice previously in the English language literature: in one report by Dahlin (1957), no localisation was mentioned: the other, by Takigawa (1971) described a patient with a chondroma in the scaphoid and lunate of the right wrist. We report two patients each with a chondr...

X-ray of left forearm and hand showing osteosclerosis, ‘bone in bone’ appearance of shaft, fracture both bones, fraying and early cupping of metaphysis and widening of ‘physis’, the growth plate and absence of carpal bones. pathological fractures with ‘bone in bone’ appearance, increase in medullary density, defective metaphyseal remodeling with fraying and early cupping and widening of...

Tumescent minimally invasive local anesthesia is eliminating the need for sedation and proximal nerve blocks as well as all of their risks, costs, and inconveniences. It has facilitated advances in procedures such as hand fracture reduction, tendon repair, and tendon transfer by allowing the surgeon to see cooperative patient active movement during the surgery. It has improved the patient exper...

We reviewed the records of 431 patients who had open reduction and internal fixation of the scaphoid performed by one surgeon (TJH) over a 13-year period. The Herbert bone screw provided adequate internal fixation without the use of plaster immobilisation, promoting a rapid functional recovery. On average, patients returned to work 4.7 weeks after surgery and wrist function was significantly im...
