Minimally invasive plate osteosynthesis (MIPO) has been used in recent years to treat fractures of the distal radius with volar locking plates. Its advantages are the preservation of the pronator quadratus and good esthetics. The MIPO technique was described originally with two incisions: one distal transverse or longitudinal incision and one proximal longitudinal incision. The trend is now to use a single longitudinal incision less than 20mm long. Functional and radiological outcomes are comparable to those of conventional techniques...

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...

K G Wang
A novel multiphase fluid-solid coupled computational framework is applied to investigate the interaction of a kidney stone immersed in liquid with a lithotripsy shock wave (LSW) and a gas bubble near the stone. The main objective is to elucidate the effects of a bubble in the shock path to the elastic and fracture behaviors of the stone. The computational framework couples a finite volume two-phase computational fluid dynamics (CFD) solver with a finite element (FE) computational solid dynamics (CSD) solver...

PURPOSE: Full or selective wrist denervation is an effective treatment for chronic wrist pain. In this cadaveric study, a volar approach for prophylactic denervation of the posterior interosseous nerve (PIN) and the anterior interosseous nerve (AIN) was assessed, which can simultaneously be performed during volar approaches for distal radius fracture fixation or in combination with metalwork removal. MATERIALS AND METHODS: In total 40 adult upper limbs, embalmed using Thiel's method, were investigated...

OBJECTIVES: In today's climate of cost containment and fiscal responsibility, generic implant alternatives represent an interesting area of untapped resources. As patents have expired on many commonly used trauma implants, generic alternatives have recently become available from a variety of sources. The purpose of this study was to examine the clinical and economic impact of a cost containment program using high quality, generic orthopaedic locking plates. The implants available for study were anatomically precontoured plates for the clavicle, proximal humerus, distal radius, proximal tibia, distal tibia, and distal fibula...

REVIEW
Åshild Bjørnerem
Cortical bone is not compact; rather it is penetrated by many Haversian and Volkmann canals for blood supply. The lining of these canals are the intracortical bone surfaces available for bone remodeling. Increasing intracortical bone remodeling increases cortical porosity. However, cortical bone loss occurs more slowly than trabecular loss due to the fact that less surface per unit of bone matrix volume is available for bone remodeling. Nevertheless, most of the bone loss over time is cortical because cortical bone constitutes 80% of the skeleton, and the relative proportion of trabecular bone diminishes with advancing age...

PURPOSE: The purpose of this study was to investigate the early complications associated with the dorsal approach to the proximal radius. This approach, also called the Thompson approach, is used relatively infrequently for the treatment of forearm fractures. It is primarily reserved for proximal one-third radius fractures where a volar plate may not be placed sufficiently proximal for adequate fixation. METHODS: A retrospective chart review was performed on forearm fractures performed at our institution...

INTRODUCTION: Orthopedic injuries are the most common types of traumatic injuries and present as fractures of the limbs, pelvis, and vertebrae or lesions in soft tissues, muscles, ligaments, and tendons. The upper limb fractures occur in distal radius and ulna, metacarpals, fingers, scapula, and carpal bones, Proximal, diaphysis, distal humerus, clavicle, proximal ulna and radio and distal humero and humero, radio, ulna, and metacarpo. The objective of this project was to accurately describe the occurrence of injuries of the upper extremity and the mechanisms of such injuries in a representative sample of Iranian population...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

INTRODUCTION: At present, surgical treatment of comminuted radial head fractures without associated instability continues to be controversial. When anatomical reconstruction is not possible, radial head excision is performed. However, the appearance of long-term complications with this technique, along with the development of new radial head implants situates arthroplasty as a promising surgical alternative. The purpose of the present study was to compare the mid-term functional outcomes of both techniques...

Osteoporosis is a metabolic bone disorder that is characterized by low bone mass and micro-architectural deterioration of bone tissue. Fractures of the proximal femur, the vertebrae and the distal radius are the most frequent osteoporotic fractures, although most fractures in the elderly are probably at least partly related to bone fragility. The incidence of fractures varies greatly by country, but on average up to 50% of women >50 years of age are at risk of fractures. Fractures severely affect the quality of life of an individual and are becoming a major public health problem owing to the ageing population...

BACKGROUND: Operative treatment of the scaphoid nonunion includes avascular corticocancellous and cancellous bone grafts and increasingly the use of vascular pedicled and free vascular corticocancellous grafts. Especially the latter require a fair amount of operative expertise and experience in microsurgical techniques. OBJECTIVE: Which criteria lead to the decision for or against an avascular graft used for reconstruction of scaphoid nonunion? Is our current classification system of a scaphoid pseudarthrosis able to illustrate our diagnostic potential in a way that makes us refer to operative procedures? METHODS: Evaluation of current literature and expert opinions RESULTS: Avascular bone grafts show a high union rate as long as a sufficient vascularisation of the remaining fragments is present...

BACKGROUND: Nonunion of the scaphoid as a result of proximal fractures, failed surgical reconstruction, and especially avascular fragment necrosis are possible indications of vascularized bone grafts. Various techniques of vascularized (pedicled and free) grafts have been described. Pedicled grafts from the direct vicinity of the wrist provide several benefits. Harvest-site morbidity is reduced and preserved graft perfusion, without the need for blood vessel anastomosis, may lead to an improved consolidation...

Deformity of wrist is very common after mal union of extra articular fractures over distal end of Radius. It causes limitation of movements too in different directions with or without pain. Deformity may be treated by different types of corrective osteotomy. We treated cases of this type of malunion with Fernandez osteotomy. This study is to observe the amount of correction and recovery of functional status in patients with malunited distal radius fractures treated with Fernandez osteotomy. This is a prospective study...

Since the in vitro and in vivo anti-osteoporotic effects of Pueraria mirifica (PM) in rodents have been verified, its activity in menopausal monkeys was evaluated as required before it can be applicable for human use. In this study, postmenopausal osteoporotic monkeys were divided into two groups (five per group), and fed daily with standard diet alone (PMP0 group) or diet mixed with 1,000 mg/kg BW of PM powder (PMP1000 group) for 16 months. Every two months, the bone mineral density (BMD), bone mineral content (BMC) and bone geometry parameters (cortical area and thickness, and periosteal and endosteal circumference) at the distal radius and proximal tibia were determined using peripheral quantitative computed tomography together with plasma and urinary bone markers...

BACKGROUND: The purposes of this study were to quantitatively analyze osteophyte formation of the distal radius following scaphoid nonunion and to investigate how fracture locations relate to osteophyte formation patterns. METHODS: Three-dimensional surface models of the scaphoid and distal radius were constructed from computed tomographic images of both the wrists of 17 patients' with scaphoid nonunion. The scaphoid nonunions were classified into 3 types according to the location of the fracture line: distal extra-articular (n = 6); distal intra-articular (n = 5); and proximal (n = 6)...

BACKGROUND: Long-term outcomes of radial head resection for radial head fracture have shown mixed outcomes, depending on the integrity of the soft-tissue stabilizers of the elbow, forearm, and wrist. METHODS: We report a case of a symptomatic delayed proximal migration of the radius after radial head excision for radial neck nonunion which was managed with a staged radial head replacement. Informed consent was obtained from the individual in this case report. RESULTS: At 7 months after radial head replacement, the patient had 90 degrees of forearm supination and 85 degrees of pronation...

Volar plating of distal radius fractures was introduced as a means to circumvent some of the issues with dorsal-based plating but has been shown not to be a complete panacea, as other advantages and challenges have subsequently been discovered. Careful attention and proper technique must be utilized to restore and maintain volar tilt. This study reports a technique of using a locking screw as a proximal peg to reliably obtain the volar tilt in a simple fashion.
