PURPOSE: Volar distal radius plates are pre-contoured to aid restoration of anatomy during open reduction internal fixation of distal radius fractures. Incorrectly contoured plates can result in malreduction, leading to malunion, pain, and loss of function. The purpose of this study was to investigate whether adolescent distal radius anatomy on the palmar cortical surface differs from that in adults, in order to determine whether adult plates are suitable for use in adolescents. METHODS: Lateral wrist radiographs were used to measure the distal radius palmar cortical angle (PCA) in adolescent age groups (12-13, 14-15, and 16-17 years old) and compared to a skeletally mature control group (30-50 years old)...

Type 2 diabetes (T2D) patients have an increased fracture risk, which may be partly explained by compromised bone microarchitecture within the cortical bone compartment. Data on trabecular bone parameters in T2D are contradictory. By high resolution peripheral quantitative computed tomography (HR-pQCT) trabecular microarchitecture is preserved, yet larger trabecular holes are detected in T2D by MRI and DXA-based trabecular bone scores (TBS) are abnormal. To determine if there are differences in trabecular microstructure, connectivity and alignment in postmenopausal women with T2D as compared to controls, we performed individual trabecula segmentation (ITS) analysis on high-resolution peripheral quantitative computed tomography (HR-pQCT) scans of the distal radius and tibia in 92 women with (n = 42) and without (n = 50) T2D...

BACKGROUND: The volar approach is commonly used for plating intra-articular fractures of the distal radius. Despite this, certain fracture configurations are more suitable for dorsal plate fixation. This technique has not gained favour due to the reported high incidence of extensor tendon irritation and attrition ruptures. With the advent of lower profile plates this risk has decreased. METHODS: We report on forty-six cases performed in a tertiary hand centre between January 2011 and May 2014...

BACKGROUND: The volar locking plate is frequently used in the fixation of unstable distal radius fractures, but despite this there is a paucity of mid to long term outcome studies. The purpose of this study was to investigate the mid-term functional outcomes of elderly patients treated with a volar locking plate for unstable distal radius fractures. METHODS: Thirty-two patients with a mean age of 74.1 (range, 65-85) years were followed for a mean of 39.1 (range, 30-81) months...

Persistent distal radioulnar joint (DRUJ) instability after internal fixation of distal radius fractures can be managed with soft tissue or bony stabilization and prolonged immobilization. However, these strategies limit postoperative motion. To address this limitation, we report our technique of indirect ulna shortening by radial distraction followed by early mobilization and provide a case example. We use this technique in cases of persistent DRUJ instability during standard volar plating of distal radius fractures...

BACKGROUND: Distal radial fractures are one of the most common orthopaedic cases that present to the A&E department. Surgical intervention is warranted in displaced intraarticular fractures and fractures with more than the recommended angulation or shortening, and is most commonly treated with volarly placed fixed angle locking plates. The aim of this study is to determine and compare the efficacy of two different plates for surgical treatment of distal radius fractures. The VRP 2...

Flexor pollicis longus (FPL) tendon rupture is a major complication of volar locking plate fixation for distal radius fractures. The tendon rupture is usually caused by friction between the distal edge of the plate and the FPL tendon, and has been well detected recently with ultrasonography. Rarely, the volar locking plate itself entraps the FPL tendon, leading to its rupture. A 63-year-old man was consistently unable to flex his right thumb after previous surgery for a distal radius fracture at another hospital...

INTRODUCTION: In case of distal radius fractures (DRF) the distal fragment generally displaces either dorsally or volarly. Scientific literature however, seldom differentiates between volarly and dorsally displaced DRFs when reporting results. It is no clear, if the direction of displacement has an influence on the clinical and radiological outcome. This study was intended to evaluate the influence of displacement direction in adult patients with surgically treated Colles or Smith type fractures...

Extensor tendon ruptures due to volar plating in distal radius fractures have mostly been described in relation with technique failures such as screw prominence and drill penetration. We report the case of a 71-year-old female with a C2 distal radius fracture with severe dorsal metaphyseal comminution. The patient underwent surgical treatment with reduction of the large fragments and fixation with a volar locking plate; the small dorsal metaphyseal nonarticular fragments were not reduced. Six months later, the patient developed extensor digitorum communis (EDC) rupture and extensor indicis proprius (EIP) laceration in coincidence with the dorsal comminution turned into a bony spur...

PURPOSE: This study defines the sigmoid notch view of the distal radius. Specifically, we tested the null hypothesis that there is no relationship between the subchondral stripe of bone seen on a sigmoid notch view of the distal radius and the articular surface of the sigmoid notch. METHODS: We used 44 wrist specimens for anatomic and fluoroscopic analysis. We measured the articular depth of the sigmoid notch from its deepest point and classified the shape of the sigmoid notch...

The goals of distal radius fracture treatment in patients above 65 years of age would not change over time if the fracture were the only factor to consider. However, people change, and fixation methods also change. Since this fracture heals in nearly every case and volar plates have eliminated the worry of malunion, we are left with two main goals. In active patients with weakened bones, the aim is to help them regain their quality of life as quickly as possible while avoiding iatrogenic conditions. This compromise is possible because of new tools-but at what price?...

This study assessed the comprehensive incidence of tendon rupture following volar locking plate (VLP) surgery for a large number of patients with distal radius fractures (DRFs) at multiple facilities in one prefecture, Japan. During the 4-year period, 2787 patients with DRFs underwent fixation using VLP. The overall incidence rates of rupture of the FPL, the extensor pollicis longus, the flexor digitorum profundus of the index finger, and the extensor digitorum communis were 0.35% (10 patients), 0.29% (8 patients), 0...

BACKGROUND: Volar locking plate fixation of distal radius fractures is commonly performed because of its good clinical outcomes. The flexor carpi radialis (FCR) approach is one of the most popular approaches to dissecting the volar side of the distal radius because of its simplicity and safety. We describe an extremely rare case of an absent FCR identified during a volar approach for fixation of a distal radius fracture. CASE PRESENTATION: A 59-year-old woman with distal radius fracture underwent surgery using the usual FCR approach and volar locking plate...

BACKGROUND: In the literature, there are numerous studies that compare different surgical procedures in the treatment of distal radius fractures (DRF). It is, however, unknown whether operative treatment and better restoration of anatomy with volar locking plate yields a better functional outcome in the elderly population when compared with non-operative treatment. METHODS AND DESIGN: This study is a prospective, randomized, controlled, multi-center trial. The purpose will be to compare the non-operative and operative treatment of initially or early malaligned distal radius fractures in patients aged 65 and older...

In spite of the more popular volar approach for plating of distal radius fractures (DRFs), there are still indications for dorsal plating and even combined dorsovolar plating in complex DRFs. Dorsal plating carries a concern for complications such as tenosynovitis, extensor tendon adhesions, and delayed extensor tendon ruptures. These risks can be minimized by use of modern low-profile plates and the use of an extensor retinaculum flap to cover the distal plate and screws. We describe the technique of the dorsal retinaculum flap for dorsal plating of DRFs...

BACKGROUND: Complications related to extensor tendons have begun to increase with the use of volar plates in the treatment of distal radius fractures. In this study, we aimed to compare four-plane radiography and ultrasonography in the evaluation of dorsal cortex screw penetration following volar plate fixation. METHODS: We recruited 47 patients (33 males, 14 females, mean age 37.4 years; range 18-58 years). To evaluate dorsal screw penetration in all patients, we performed radiographs at 45° pronation, 45° supination and obtained dorsal tangential graphs at maximum palmar flexion, and a wrist lateral radiograph...
