Hamate-pisiform coalition is an exceptional form of carpal coalition. Case reports are essential to gain a better understanding of this variant. We report a case of congenital bilateral hamate-pisiform coalition in a 20-year-old male discovered in the context of a right wrist trauma. Radiographs also revealed a bilateral scapholunate diastasis. Clinical examination and radiological findings suggested that the right wrist scapholunate diastasis was related to scapholunate instability. Left wrist scapholunate diastasis could be related to (1) a pathological feature or (2) a normal variant associated with hamate-pisiform coalition...

The management of distal radius fractures has evolved over time from a largely nonoperative paradigm to a more commonly performed operative procedures today. Surgical trends have similarly developed, with dorsal plating falling out of favor due to complications involving extensor tendon pathology as well as due to the ubiquity of the volar plate along with the advent of locking plate technology. However, with the improvement in design of newer generation dorsal plates, this technique should be used in the appropriate clinical situation, including dorsal comminution and angulation with concomitant carpal pathology...

We present a case of dislocation of the fourth carpometacarpal joint without associated fractures. This is the first case to be reported in the literature. Carpal injuries are uncommon; it is even rare for isolated carpometacarpal dislocation to occur without associated fractures. The injury is difficult to diagnose because of the swelling of the hand and may be missed on several occasions. A lateral radiograph of the wrist has been found to be mandatory to its precise diagnosis if suspected. Early recognition and anatomical reduction are essential in achieving good long-term outcomes...

BACKGROUND: Displaced Colles' fractures are treated by manipulation and below elbow cast application. Malunion is a common complication, resulting in pain, mid-carpal instability, and post-traumatic arthritis. Fracture stabilization by percutaneous pinning is a simple, minimally invasive technique that helps prevent displacement of the fracture, thereby minimizing complications. This study aims to assess the amount of collapse after closed manipulation and percutaneous pinning with Kirschner wires (K-wires) and its correlation with the functional outcome of the wrist after union...

PURPOSE: To study the intraosseous 3-dimensional microvasculature of the capitate bone using a novel high-resolution micro-computed tomography (μCT) imaging technology, and to examine the blood supply as it relates to the most common fracture types. METHODS: Ten cadaveric wrists were injected with a lead-based contrast agent. The capitates were harvested and imaged using a μCT scanner. The intraosseous vascularity was incorporated into a 3-dimensional image. We measured the vascular pattern as well as the vessels' cross-sectional area, number, and distribution...

INTRODUCTION: Distal radius fracture are common injuries but no gold standard for their therapy exists. The aim of this study was to evaluate the quality of fracture care in distal radius fractures using an intramedullary implant (Targon DR interlocking nail). The nail had been developed to minimize the surgical exposure, increase fixation strength, to prevent tendon irritations and to allow for a fast return to activity. PATIENTS AND METHODS: Prospective study reports the result of 43 patients with an age over 70 years (range 70-91 years) treated by closed reduction and intramedullary fixation...

Scaphoid fractures constitute 71% of all carpal bone fractures.(1) Early diagnosis and treatment has significant bearing on fracture union rates and better clinical outcomes. While displaced fractures can be readily seen on plain radiograph, undisplaced fractures can require advanced imaging modalities to confirm that diagnosis. Advanced imaging such as Magnetic Resonance Imaging (MRI), Computerised tomography (CT) and bone scintigraphy are routinely used for the diagnosis of scaphoid fractures but require significant radiation exposure, increased cost and can be difficult to access...

: We analysed scaphoid deformity as a result of surgical treatment of scaphoid fracture nonunion and assessed the deformity associated with a dorsal intercalated segmental instability pattern of carpal malalignment. A total of 45 patients who were treated for scaphoid fracture nonunion were included in the study. The height-to-length ratio of the scaphoid was measured on computed tomographic images and used to assess scaphoid deformity. Carpal malalignment was quantified based on the radio-lunate angle...

The volar Henry approach is most commonly used for surgical fixation of distal radius fractures. However, this approach is limited in achieving adequate exposure for the fixation of the volar-ulnar portion of the distal radius, rendering it difficult for the ideal placement of the fixation construct. We propose the use of the extensile volar-ulnar approach for fixation of distal radius fracture involving a small volar-ulnar fragment. This approach allows optimal reduction of the sigmoid notch and the volar lunate facet, which anatomically reduces both the radiocarpal joint and the sigmoid notch...

In this literature review, the authors analyse the prognostic factors in the curative treatment of scaphoid non-unions. The main negative prognostic factors are smoking, the time elapsed since the fracture, and avascular necrosis of the proximal fragment. If the latter is present, the revascularization by a pedicle or microsurgical bone autograft is probably the treatment of choice. In non-unions without evidence of osteonecrosis, vascularized bone grafts are probably not superior to conventional bone grafts, which can presently be performed under arthroscopic control, with minimal morbidity...

Adaptive carpal malalignment is the consequence of malunion of the distal radius. Since the radial metaphysis and capitate have to be aligned, any disorientation of the radial epiphysis will force the proximal carpal row to adapt, as it is the only mobile element. There are two types of adaptation depending where the compensative occurs: (1) midcarpal - leading to flexion between the lunate and capitate, with the lunate maintaining a normal relationship with the radial epiphysis axis; (2) radiocarpal - combining flexion and dorsal displacement of the lunate relative to the axis of the radial epiphysis, with the midcarpal joint remaining aligned...

REVIEW
Steven C Haase
Modern competitive diving-especially platform diving-applies dramatic stress to the upper extremity. Some stress occurs during handstand-style takeoffs, but more force is delivered to the hand, wrist, elbow, and shoulder during hands-first entry. Hand positions that minimize the amount of splash result in forceful wrist extension. This repetitive impact can lead to chronic upper extremity pain and acute injuries that require operative intervention. Many divers use taping and bracing to prevent or treat this type of injury, but these are only modestly effective...

: Reformatted magnetic resonance imaging scans of 27 normal wrists were examined in incremental degrees of rotation around the central axis of the radial shaft to 30° in both directions from true lateral. A line was superimposed on the outer border of the radial dorsal cortex and continued distally to the carpal region. Measurements were made from the superior pole of the lunate to this line. This distance did not change significantly with rotation. This allows a quick and accurate way of assessing distal radial fracture reduction from poorly taken lateral radiographs...

Scapholunate advance collapse (SLAC) and Scaphoid nonunion advance collapse (SNAC), are the two most common patterns of postraumatic wrist arthritis. SLAC wrist develops after attenuation, either traumatically or atraumatically, of the scapholunate ligament. Atraumatic causes of SLAC wrist include calcium pyrophosphate dehydrate deposition disease, reumathoid arthritis, neuropathic diseases, and b2-microglobulin asociated amyloid deposition diseases. On the other hand, SNAC wrist develops following a scahpoid fracture that has progressed to a nonunion...

PURPOSE: Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft...

Scaphoid fracture is the most common carpal fracture of the upper extremity and a significant proportion of these can eventually progress to nonunion. Excision of pseudoarthrosis and fibrous scar tissue at the nonunion site is regarded as one of the important steps in management of scaphoid nonunions. We describe a technique of internal bone grafting, where curettage of the nonunion site was performed through a drill hole in the scaphoid and bone graft was packed through this same hole before fixation with a headless compression screw...
