We reconstructed three-dimensional images of radius and ulna in 38 forearms of 25 patients with congenital proximal radioulnar synostosis from their computed tomographic studies. We also analysed correlations between the deformities of radius and ulna and degrees of fixed pronation of these forearms. The average ulnar deviation, flexion and internal rotation deformities of the radius were 6°, 3° and 18°, respectively. The average radial deviation, extension and internal rotation deformities of the ulna were 3°, 4° and 30°, respectively...

Primary bone tumors around the elbow represent <1% of all the skeletal tumors. Surgery with or without adjuvant therapy (radiotherapy, chemotherapy) is the treatment of choice for malignant tumors. Reconstruction of the elbow and forearm in malignant tumors is challenging as it involves a complex interplay between multiple joints which need to be stabilized for the optimal functional outcome. We describe a new technique for the reconstruction of the elbow after resection of a proximal ulna tumor with articular radio-ulnar synostosis with the creation of a single bone forearm...

BACKGROUND: Congenital radioulnar synostosis (CRUS) refers to an abnormal connection between the radius and ulna due to embryological failure of separation. Derotational osteotomy has been advocated for children with functional limitations, although historically this procedure has been associated with a 36% complication rate including compartment syndrome and loss of correction. METHODS: A retrospective evaluation of consecutive patients who underwent derotational osteotomy for CRUS at a single institution was performed...

Congenital radial head sub-luxation was diagnosed in a 7-month-old, neutered male shih tzu that presented with a limb deformity and severe lameness of the right fore limb. Radiography revealed a craniolateral sub-luxation of the right radial head, which was treated by radial head ostectomy, fixation of the radius to the ulna with a screw and joint stabilisation with suture-anchors and cerclage wire. Surgical treatment followed by physiotherapy resulted in a fully functional, well-aligned and non-painful elbow...

We describe a 0.73 Mb duplication of chromosome 22q11.21 between LCR-B and LCR-D and a missense mutation in a conserved C2H2 zinc finger domain of SALL4 in a cognitively normal patient with multiple skeletal anomalies including radioulnar synostosis, thumb aplasia, butterfly vertebrae, rib abnormalities, and hypoplasia of the humeral and femoral epiphyses. 22q11.21 is a common site for microdeletions and their reciprocal microduplications as a result of non-allelic homologous recombination between its multiple low copy repeat regions (LCR)...

BACKGROUND: Fractures of the proximal ulna are rare and usually managed surgically. Strong fixation of the harware is essential to obtain good outcomes. We report our experience with pre-contoured locking plate fixation of complex olecranon fractures and present a critical appraisal of the outcomes. HYPOTHESIS: Pre-contoured locking plates provide good outcomes, but their clinical tolerance may be limited in some instances. MATERIALS AND METHODS: From September 2009 to December 2011, 28 patients were managed using a pre-contoured locking compression plate (LCP(®))...

We report this 47-year-old man who presented with polytrauma following a fall from a roof in March 2011. He sustained a head injury and a complex, comminuted forearm fracture. He underwent an open reduction and internal fixation of the fracture at the time of injury, but later developed a rigid type 2 diaphyseal radioulnar synostosis, with loss of forearm rotation. Synostosis excision and a radial artery perforator-based adipofascial interposition flap to prevent recurrence has resulted in a good functional outcome and no recurrence at 2...

A 32-year-old lady presented to our clinic with persistent painful restriction of her dominant forearm movements for three months after tension band wiring of olecranon. She had full elbow flexion and extension; however, her forearm rotations were restricted and painful. Investigations revealed prominent tips of the wire, eroding the radial tuberosity with heterotopic ossification between the radius and ulna. As there was no synostosis, the patient had implant exit. During surgery, before implant removal, examination under anaesthesia revealed a mechanical block of the rotation beyond 30° on pronation and supination from neutral...

PURPOSE: To report the effectiveness of single derotation osteotomy at the radial diaphysis for the treatment of congenital radioulnar (RU) synostosis. METHODS: Since 2000, we performed 35 radial diaphysis osteotomies on 17 boys and 9 girls younger than 9 years old (average, 5 y). The radius was cut at the midshaft and manually rotated to a neutral position. A long-arm cast was applied for 4 to 6 weeks. Complications of surgeries were recorded, and pre- and postoperative forearm position was measured...

BACKGROUND: Proximal radioulnar synostosis is a complication after elbow injuries. Various treatment methods have been reported and are associated with unpredictable outcomes. In a prospective study, we evaluated the medium-term effects of proximal radial resection on wrist and elbow function and forearm rotation in 15 cases. METHODS: We treated 15 patients with posttraumatic proximal radioulnar synostosis by resection of 1 cm of the proximal radial diaphysis. On the preoperative examination and last follow-up, the Mayo Elbow Performance Score, grip force, visual analog scale for elbow and wrist score, radiographic ulnar variance changes, and elbow range of motion were measured...

BACKGROUND CONTEXT: Proximal congenital radial-ulnar synostosis (PCRUS) is defined by the development before birth of a bony bridge between the radius and ulna, usually at the proximal level, which blocks forearm rotation. This anomaly is rarely reported in the medical literature, because of its low prevalence, and treatment usually yields unsatisfactory results. The most commonly used surgical interventions are: forearm repositioning osteotomies with derotation of the radius and ulna, segmental resections of the middle third of the radius with muscular interposition, resection of the synostosis with the interposition of fatty tissue, tendons or fascia lata and resection of the proximal radius along with the transfer of the distal extensor carpi ulnaris tendon on the lateral edge of the radius...

INTRODUCTION: The treatment goal for diaphyseal forearm fractures in adults is to restore axial and rotational stability. The treatment of these fractures with intrmaedullary locked nailing remains sparse. We therefore evaluated IM nails for treating forearm diaphyseal fractures in adults. METHODS: We retrospectively reviewed adult patients with isolated unilateral or bilateral fractures of the radius, ulna, or both, who were treated with closed or mini open reduction with a new IM nail between May 2008 and January 2012 and who were followed for a least 1 year...

BACKGROUND: For congenital proximal radioulnar synostosis, both conservative and operative treatments have been described. Most of the studies describing surgical interventions are based on subjective evaluation of the forearm function and have used severe degree of forearm pronation as an indication for surgery. This study describes a single-staged rotational osteotomy of the proximal third ulna and distal third radius. The aim of the study was to assess the utility of the described surgical procedure by subjective and objective evaluations of the forearm function...

BACKGROUND: Congenital radioulnar synostosis (CRUS) causes a spectrum of presentations, most commonly a restriction of forearm rotation. Because most of these children are not treated operatively, many are not followed clinically after the diagnosis has been made. This report describes that a subset of the Cleary and Omer type IV synostoses (anterior dislocation of the radial head) can present with a progressive block to elbow flexion that worsens with growth. The location of this synostosis allows the physis of the radial head to grow untethered...

OBJECTIVE: To stabilize the distal radioulnar joint (DRUJ) by performing dorsal capsular imbrication in patients presenting with dorsal instability. The goal was to reduce pain and prevent the occurrence of posttraumatic arthrosis. INDICATIONS: Posttraumatic dorsal instability of the DRUJ with missing block while performing translational activities in the DRUJ or subluxation while actively rotating the forearm. Cases, in which other stabilizing techniques, such as, sutures of the triangular fibrocartilage complex failed...

PURPOSE: To report the method, outcome, and complications with Ilizarov external fixation for correction of congenital radioulnar synostosis with fixed forearm pronation greater than 60°. METHODS: We treated 4 patients with an average age of 11 years (range, 9-13 y). Three patients had bilateral deformity and 1 had deformity of the right forearm only. All forearms were classified as type 3 according to Cleary and Omer. Indications were severe (> 90°) bilateral pronation deformity in 3 patients, with a mean preoperative pronation deformity of 100° (range, 90° to 110°), whereas 1 patient had unilateral right forearm deformity treated for cultural reasons...
