BACKGROUND: Wrist hemiarthroplasty has emerged as a motion-sparing option for severe wrist arthritis. It is technically easy with advantages of limited bone resection and no risk of nonunion. Given the relative infancy of the procedure in clinical practice, there are limited data on patient outcomes. METHODS: Eleven patients were treated with wrist reconstructive hemiarthroplasty. Indications included 1 patient with scaphoid nonunion advanced collapse, 9 patients with scapholunate advanced collapse, and 1 patient with capitolunate arthritis...

BACKGROUND: Percutaneous techniques have been described for the treatment of nondisplaced scaphoid fractures, although less information has been reported about outcomes for unstable, displaced fractures. The aim of this study was to evaluate the union and complication rates following manual closed reduction and percutaneous screw placement for a consecutive series of unstable, displaced scaphoid fractures. METHODS: A total of 28 patients (average age, 27 years; 22 male/6 female) were treated for isolated unstable displaced scaphoid waist fractures...

INTRODUCTION: Thumb basal joint arthroplasty with removal of the entire trapezium is often followed by proximal subsidence and impingement of the thumb metacarpal to the scaphoid, which is a common cause of post-operative thumb pain. Treatment of this impingement is a challenge among surgeons. We performed suspension arthroplasty combined with intercarpal ligament reconstruction using a strip of the extensor carpi radialis longus (ECRL) tendon on a patient suffering from pain caused by this type of the impingement and obtained a successful outcome...

PURPOSE: The effect of scaphoid nonunion deformity on wrist function is uncertain due to the lack of reliable imaging tools. Advanced three-dimensional (3-D) computed tomography (CT)-based imaging techniques may improve deformity assessment by using a mirrored image of the contralateral intact wrist as anatomic reference. The implementation of such techniques depends on the extent to which conventional CT is currently used in standard practice. The purpose of this systematic review of medical literature was to analyze the trend in CT scanning scaphoid nonunions, either unilaterally or bilaterally...

BACKGROUND: Scapholunate ligament injury is a commonly occurring carpal ligament injury. Pathology associated with scapholunate ligament injury depends on several factors such as the time after injury, type of injury (instability) and the development of osteoarthritis. The aim of this study was to investigate and compare contact mechanics in the lunocapitate and scaphocapitate joints in the normal, injured (scapholunate dissociation) and repaired (postoperative) wrist. METHODS: Four human subjects with scapholunate ligament dissociation participated in this study...

INTRODUCTION: Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. CASE PRESENTATION: A 38-year-old man complaining of a 4-month history of mild pain on the base of his right thumb...

A congenital megalourethra is an enlargement of the pendulous urethra without evidence of distal obstruction. A 1-month-old boy presented to us with complaint of weak stream, ballooning of the penis before and during voiding and post voiding dribbling, since birth. Physical examination and cystourethroscope confirmed the diagnosis of congenital scaphoid megalourethra. He underwent reduction urethroplasty. During postoperative follow up, he had normal looking penis with good urinary stream.

Scaphoid fractures are the most common type of carpal injuries that occur in children and adolescents. The injury pattern seen in children and adolescents who have scaphoid fractures has recently shifted to resemble that of adults who have scaphoid fractures, with scaphoid waist fractures being the most common injury pattern. This shift has been attributed to increased body mass index in children and adolescents as well as more intense participation in extreme sports by both children and adolescents. The diagnosis of scaphoid fractures is based on both a clinical examination and radiographic fi ndings...

The goal of wrist denervation is to decrease pain at the wrist, whether caused by an intra- or extra-articular problem or even when the reason for the pain is unknown. It is an alternative to partial or total arthrodesis and proximal row carpectomy. Our hypothesis was that wrist denervation with a two-incision technique was a reliable and efficient way to treat painful degenerative wrists. Thirty-three patients, 48years old on average, were included in this study. Indications were scapholunate advanced collapse (SLAC) in 18 cases, scaphoid nonunion advanced collapse (SNAC) in 10, distal radius fracture sequelae with advanced radiocarpal osteoarthritis in 4, and post-traumatic ulnocarpal impingement in 1 case...

The wrist is essential for hand function. Yet, due to the complexity of the wrist and hand, studies often examine their biomechanical features in isolation. This approach is insufficient for understanding links between orthopaedic surgery at the wrist and concomitant functional impairments at the hand. We hypothesize that clinical reports of reduced force production by the hand following wrist surgeries can be explained by the surgically-induced, biomechanical changes to the system, even when those changes are isolated to the wrist...

The radial approach to the wrist is already used in several surgical techniques such as radial styloidectomy and Zaidemberg's vascularized radial graft. The aim of our work was to describe the surgical anatomy of that approach and to determine the acceptable limits of radial oblique styloidectomy that does not damage the anterior and posterior radiocarpal ligaments. This radial approach was performed on 11 cadaver specimens. The superficial branches of the radial nerve and the antebrachial cephalic vein were carefully located in the superficial plane...

REVIEW
Steven Regal, Aakash Chauhan, Peter Tang
Cortical bone grafting is commonly required in the finger, hand, and carpus when managing bony trauma. A donor site that can provide a small or large amount of cortical bone graft that is easily accessible and within the same surgical field would be the ideal donor site. In high-energy injuries, a long cortical graft may be needed to reconstruct massive bony defects. In low-energy injuries such as scaphoid nonunions in which a wedge graft is needed, a reliable and easily accessible source of bone grafting would be beneficial...

Background: Whether antenatal and neonatal vitamin D status have clinical relevance in fracture prevention has not been examined extensively, although observational studies indicate that fetal life may be a sensitive period in relation to bone growth and mineralization during childhood.Objective: We examined whether 25-hydroxyvitamin D3 [25(OH)D3] concentrations in stored neonatal dried blood spot (DBS) samples are associated with pediatric fracture risk. We hypothesized that in particular, low neonatal vitamin D status may be a risk factor for fracture incidence among children...

BACKGROUND: Distal scaphoid excision is one treatment option for osteoarthritis of the scaphotrapeziotrapezoid (STT) joint following failure of conservative measures. Potential complications of this procedure include injury to the carpal ligaments, cartilage, and radial artery. METHODS: A single case was identified by the senior author, and the medical record was reviewed for surgical notes, progress notes, and radiographs. RESULTS: A 68-year-old male sustained ruptures of the flexor digitorum superficialis (FDS) and flexor digitorum profundus to the index finger 3 years following a distal scaphoid excision for symptomatic STT osteoarthritis...

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 fractures achieved radiographic union at an average of 57 days (range, 35-70 days), requiring no additional procedures...

Avascular necrosis (AVN) of the capitate is a rare clinical entity for which a variety of treatment options have been described, ranging from immobilization to microvascular bone transfer. Outcomes following medial femoral condyle corticocancellous free flap reconstruction have not been reported for this specific pathology. We present the case of a 16-year-old girl with posttraumatic capitate AVN who was treated with curettage and medial femoral condyle corticocancellous vascularized bone grafting. At 18 months after surgery, the patient remains pain-free and had resumed all activities including lifeguarding by 6 months after surgery...

AIM: To investigate the kinematics of the scaphoid while the wrist was in radioulnar motion using gated four-dimensional computed tomography (4DCT) imaging. MATERIALS AND METHODS: Six cadaveric wrist specimens were scanned in the following order of capsulotomy and ligament sectioning: (1) ligaments intact, (2) capsulotomy, (3) scapholunate ligament division, and lastly, (4) lunotriquetral ligament division. A three-dimensional model was then reconstructed to analyse the translation and angular displacements of the scaphoid...

We assessed the effect of four-corner intercarpal fusion with locking plate without bone graft on daily activities and pain in patients with stage II and III scapholunate advanced collapse and scaphoid nonunion. Twenty-one patients who underwent four-corner fusion with scaphoidectomy without bone graft were evaluated with the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Visual Analog Scale (VAS) pain scores before and 16 months after surgery. We also compared postoperative grip strength between the operated and the healthy side...
