SummaryA fracture of the proximal 1/3 of the ulna, with concurrent fractures of the proximal radial physis and the distal 1/3 of the diaphysis of the radius occurred in a three-month-old, male, neutered, Domestic Shorthaired cat. The ulnar fracture was stabilised with an intramedullary pin. The proximal radial physeal fracture was reduced and stabilised with two crossed Kirschner wires. The proximal radius was secured to the ulna with an additional Kirschner wire. The distal radial diaphyseal fracture was stabilised with a five-hole, 2.0 mm dynamic compression plate (DCP). Six weeks postoperatively the cat was using the limb comfortably and demonstrated a full range of motion of the elbow joint. There were radiographic signs of fracture union and the radioulnar pin had migrated. The Kirschner wires were removed. Follow-up at 18 months postoperatively revealed that the cat was using the limb normally without any lameness. A full, pain-free range of motion was present in the joints of the left thoracic limb.

Chapter 15 discusses radius and ulna trauma. Forearm fractures are common and may be isolated to the ulna or more commonly involve both bones. Fractures of the radius or ulna are usually because of direct trauma and are often displaced. Depending on their complexity, isolated fractures of the ulnar diaphysis may be treated nonoperatively or operatively whereas both bone (radius and ulna) diaphyseal fractures are typically treated operatively. Galeazzi fracture-dislocations are comprised of radial diaphyseal fractures in association with distal radioulnar joint (DRUJ) dislocation/subluxation. Monteggia fracture-dislocations are comprised of a proximal ulnar fracture in association with radial head dislocation. In type IV Monteggia injuries, there is an additional fracture of the proximal radial diaphysis. Essex-Lopresti fracture-dislocations include radial head fractures in association with DRUJ dislocation/subluxation.

Ulnar Fracture

SummaryA 5-month-old German shepherd dog with a combination of a proximal radial physeal fracture and a proximal ulnar diaphyseal comminuted fracture, with cranial displacement of their distal fragment, was presented. This fractures combination resembles type I Monteggia fracture. After surgical reduction of the fractures, three full-cerclage wires were used to stabilize the ulnar fracture, and two positional screws were placed across the radius and ulna immediately distally to the growth plate to hold these bones in apposition. Four weeks post-operatively, the screws were removed since sufficient callus had been formed and the dog was free of lameness. It seems that if the appropriate conditions for a type I Monteggia fracture develop in an immature dog, proximal radial physeal fracture instead of radial head luxation may accompany ulnar diaphyseal fracture.

Radius Fractures

Intrafocal pinning of distal radius fracture is indicated in unstable distal radius fractures without significant intra-articular displacement. It is a simple and effective, minimally invasive method of fixation for achievement of alignment and stability of unstable fractures. The study was conducted between November 2013 and October 2016. Patients attending the emergency and outpatient departments with history of trauma followed by pain and swelling of wrist, were evaluated clinically & radiologically. Patients with distal radius fracture who met the criteria were enrolled in the study. The operation was performed either under regional anaesthesia or intra venous anaesthesia. Reduction was carried out under image intensifier guidance and intrafocal pinning was undertaken with 2 Kirschner wires as described by Kapandji. Above elbow slab was applied for 3 weeks. Kirschner wires were removed at 6th week. Follow ups were done with radiological and functional evaluation on 1st week, 3rd week, 6th week, 12th week and 6 month. Of the 30 cases enrolled in our study, the age ranged from 40 to 72 years and the mean age of the patients was 54.77 years. The female/male ratio was 5:1 and the majority (83%) of patient sustained injury due to trivial trauma. All fractures united by 6 weeks. In the final follow up at 6th month, assessment of range of motion showed almost full range of motion. Functional evaluation was carried out with Gartland & Werleys Demerit point system (modified by Sarmiento et al). According to the score, 9 patients had excellent, 19 had well and 2 had fair results. None of the patient had poor results. Kapandji intrafocal pinning provides a stable fixation and good functional outcome in extraarticular distal radius fractures with few complications only.

SummaryObjectives: To evaluate the use of Kirschner wires for treatment of fractures of the lateral aspect of the humeral condyle in growing dogs.Methods: Retrospective analysis of 35 elbow fractures (33 dogs) of the lateral aspect of the humeral condyle treated by insertion of multiple transcondylar and one anti-rotational Kirschner wires. Radiographic and clinical re-evaluations were carried out immediately after surgery, at four weeks and, when required, at eight weeks postoperatively. Long-term follow-up was planned after a minimum of six months. The relationship between different implant configurations and clinical outcome was analysed statistically.Results: Complete functional recovery was seen in 31 elbows (30 dogs), three elbows (2 dogs) had reduction in the range of motion, and one elbow (1 dog) had persistent grade 1 lameness two months postoperatively. Major complications occurred in eight elbows (8 dogs) and all were resolved by implant removal. Implant configuration did not affect outcome. Long-term evaluation in 12 cases with a mean follow-up of four years showed absence of lameness, normal function and no or mild radiographic evidence of osteoarthritis in 11 cases.Clinical significance: Fracture of the lateral aspect of the humeral condyle in growing dogs can be successfully treated by multiple transcondylar convergent or parallel Kirschner wires, resulting in adequate fracture healing.

A galeazi fracture is defined as a fracture of the shaft of the radius with dislocation of the distal radioulnar joint (DRUJ). Isolated radial shaft fractures with or without DRUJ dislocation in children are unusual in clinical practice. If there is fracture the degree of angulation is measured and accordingly managed. A 12 years boy came to the casualty department of Community Based Medical College Hospital Bangladesh (CBMCH,B) with the history of fall from bicycle on out stretcher right hand 5 years back, diagnosed to have fracture shaft of right radius. X-ray examination revealed old fracture at the junction of the middle and lower third of right radial shaft with feature of nonunion with volar angulation 30° (180-1500) and interosseous angulation 150 (180-165°). Patients was operated by open reduction and internal fixation (ORIF) of the fracture using dynamic compression plate (DCP) and screws and we corrected the angulation to near normal status and also correction of DRUJ done to its near normal anatomy. Postoperatively wound healed well and patient achieved full range of motion by three weeks. Radiologically the fixation was satisfactory and at the 6 weeks fracture was united. In conclusion, an old unusual galeazzi fracture dislocation in a child below 14 years with volar / dorsal / interosseus angulation more than 150 and rotational angulation more than 30° must be managed surgically to get near normal anatomy of bone as well as near normal range of motion.

Abstract CASE DESCRIPTION A 3-year-old 5-kg sexually intact female silvery langur housed in a single-species group at a zoological institution was presented because of acute trauma to the left forelimb. CLINICAL FINDINGS Radiography of the left forelimb revealed a type II Monteggia fracture (proximal ulnar fracture with cranial displacement and caudal luxation of the radial head). During surgery, disruption of the annular ligament and rupture of the lateral collateral ligament were noted. TREATMENT AND OUTCOME The langur underwent open reduction and internal fixation of the ulnar fracture and placement of a radioulnar positional screw, a prosthetic lateral collateral ligament, and a temporary hinged type 1A external skeletal fixator. The langur was returned to group housing, underwent behavioral training, and was periodically anesthetized for physical therapy sessions to improve range of motion of the left elbow joint. The external skeletal fixator was removed 4 weeks after surgery, and the radioulnar positional screw was removed 6 weeks after surgery. Three months after surgery, the range of motion of the langur’s left elbow joint was considered normal, and the animal returned to normal activity. CLINICAL RELEVANCE For the captive silvery langur of the present report, surgical stabilization and postoperative management of a type II Monteggia fracture of the left forelimb were successful with recovery of elbow joint function. These techniques may be applied to other captive nonhuman primates, including those that brachiate or are members of social species that must be housed with conspecifics in the postoperative period to maintain group dynamics.

Background: Limited wrist arthrodesis with scaphoid excision is a useful treatment for scapholunate advanced collapse (SLAC) of the wrist. Multiple Kirschner wires were originally used for internal fixation of the four carpal bones, however long-term cast immobilization, pin tract infection, and hardware removal are still problematic. We introduce and evaluate the clinical outcomes of an internal fixation technique; triangle fixation for four-corner fusion, using three headless screws, as an alternative to conventional multiple Kirschner wires for the treatment of SLAC wrist. Methods: Five male patients with SLAC wrist secondary to three scaphoid nonunions and two scapholunate dissociations were treated with four-corner fusion using triangle fixation with three Double-threaded Japan screws. The mean age was 59.5 years (35–79 years) and the mean follow-up period was 40 months. After surgery, short arm splints were applied for 3–4 weeks, and then range of motion exercises were initiated. Results: Wrist range of motion and grip strength both improved postoperatively. At the final follow-up evaluation, bone union was completely achieved and satisfactory pain relief was observed in all patients. Conclusions: Compared with the conventional Kirschner wire technique, the present technique shortens the period of splint immobilization due to a strong compression force in a skewed position, does not require pin removal or cause pin tract infections, and provides satisfactory results.

<p>Adsorption isotherms are an essential tool in chemical physics of surfaces. However, several approaches based on a different theoretical basis exist and for isotherms including capillary condensation existing approaches can fail. Here, a general isotherm equation is derived and applied to literature data both concerning type IV isotherms of argon and nitrogen in ordered mesoporous silica, and type II isotherms of disordered macroporous silica. The new isotherm covers the full range of partial pressure (10<sup>-6</sup> - 0.7). It relies firstly on the classical thermodynamics of cluster formation, secondly on a relationship defining the free energy during the increase of the cluster size. That equation replaces the Lennard-Jones potentials used in the classical density functional theory. The determination of surface areas is not possible by this isotherm because the cross-sectional area of a cluster is unknown. Based on the full description of type IV isotherms, most known isotherms are accessible by respective simplifications. </p>
