ABSTRACT Fractures of the distal humerus that involving the condyles often requires extensive surgical approach for treatment, leading to a prolonged recovery time. In a West Highland White Terrier dog two years old, with a fracture of the lateral humeral condyle portion and elbow luxation, was performed a closed technique for luxation reduction, fracture reduction was performed by digital pressure and percutaneous osteosynthesis by introduction of a Kirschner wire of 2 mm diameter, accompanied by Robert-Jones bandage modified for 6 weeks. Limb function was recovered in the immediate postoperative, the wire was removed six weeks after, non-was observed postoperative complications, and full functional recovery of the limb was clinically evident. This suggests that this technique could be an option in cases of condylar fractures in small-sized dogs.

Abstract Objective The aim of this study was to investigate the effects of an induced incomplete ossification of the humeral condyle (IOHC) lesion on ex vivo canine humeral condylar biomechanics. Study Design Nine paired cadaveric elbows were collected from mature dogs weighing between 20 and 25 kg. Left and right limbs were randomized to IOHC or normal groups. Limbs were prepared for mechanical testing; ligaments were preserved and an IOHC lesion was created. Elbows were potted, positioned into a biomaterials testing system at an angle of 135 degrees and axially loaded to failure at a rate of 30 mm/minute. Results Induced IOHC lesions reduced peak load (p = 0.02) when compared with an intact humerus. There was no difference between stiffness (p = 0.36) of intact humeri or humeri with an induced IOHC lesion. An induced IOHC lesion increased (p = 0.012) the probability of intracondylar fracture under load. Conclusion Cadaveric humeri are weakened by the creation of an intracondylar osteotomy and fractures secondary to induced IOHC are similar to spontaneous humeral condylar fractures. These findings support the hypothesis that naturally occurring IOHC weakens the humeral condyle and may predispose to humeral condylar fracture.

Abstract Background: The purpose of this study was to investigate the effect of staged surgery (open reduction/internal fixation and osteotomy) for cubitus valgus after non-union of lateral condylar fractures of the distal humerus in older children.Methods: From January 2010 to January 2013, 9 patients were treated with two-staged surgery (open reduction/internal fixation and osteotomy). The study included 5 males and 4 females, with a mean age of 12.7 years. The interval from fracture to the first surgery was 8.2 years on average. All patients had symptoms of injury of the ulnar nerve and instability of the elbow. The first surgery included internal reduction, internal fixation, and bone grafting, exposing the elbow through a lateral approach. The procedure included clearing the peripheric callus and proximal distal fracture end cicatrix with rongeur until cancellous bone was exposed, and fixation of the lateral condylar fragment with a hollow screw 4.0 mm in diameter and smooth Kirschner wire. The limb was immobilized in a long arm cast with the elbow at 90 degrees of flexion and the forearm in neutral rotation for 3 weeks, and active exercises were begun after removal. The second surgery, osteotomy of the supracondylar humerus, was completed after 6 months to correct cubitus valgus. Internal fixation from the osteotomy was removed 6 months later.Results: Six months after the second surgery, follow-up revealed that in all patients the lateral condylar fractures attained clinical union and cubitus valgus was corrected. Elbow function recovered well without arthrochalasis or humeral condylar avascular necrosis. All patients’ ulnar nerve injury symptoms disappeared.Conclusion: Staged surgery to treat cubitus valgus secondary to lateral condylar fracture non-union in older children serves to first provide elbow stability, then to correct cubitus valgus. Staged treatment may make up for the deficiencies of conventional treatment. However, due to our relatively short follow-up time, the long term effects are unknown.

To report the surgical details and results of our technique of Transmasseteric antero-parotid approach (TMAP) through modified preauricular lazy ‘S’ incision for management of mandibular condylar fractures. This was an observational analysis of 65 patients where 25 patients were treated with conventional preauricular approach, 25 patients with closed reduction and 15 patients with a mean age of 29.4 years with condylar fractures were treated by TMAP technique between September 2016 to June 2018. Aim of the study was to evaluate the proficiency of TMAP approach for open reduction and internal fixation (ORIF) of condylar fracture. The only complication which was noticed was sialocele formation and managed by drainage. TMAP is versatile since it avoids facial nerve damage as it involves identification and preservation of facial nerve and   has less chances of post-operative complications related to facial nerve injury. The accessibility achieved by this approach is fair enough to facilitate anatomic reduction and fixation of condyle.

Background. Fractures of the mandible are common in elderly patients, and among them, condylar fractures are the most frequent type. A change in occlusion is the most common physical finding in patients with fractures of the mandible. Therefore, it is challenging to identify mandibular fractures in posterior edentulous patients due to the lack of posterior occlusal contacts. It is crucial to do radiological investigations in such patients to exclude fractures. Case Presentation. This article describes a case of delayed diagnosis of a unilateral mandibular condylar fracture for a week’s duration and treating the condition as temporomandibular pathology in a posterior edentulous, 52-year-old patient. Conclusion. This clinical case highlights the importance of radiological investigations and occlusal analysis for early diagnosis of condylar fractures, particularly in posterior edentulous patients, lacking posterior occlusal contacts.

<p class="abstract"><strong>Background:</strong> Inter-condylar fractures represent one of the most complicated and challenging fractures in the upper extremity. The results of managing these fractures non-operatively are limited by failure to get anatomical reduction and early mobilization, which often results in painful stiff elbow and/or pseudo-arthrosis. The objective of this study was to evaluate and analyse the role of open reduction and internal fixation in inter-condylar fractures of distal humerus.</p><p class="abstract"><strong>Methods:</strong><strong> </strong>The present study was done in Malla Reddy Institute of Medical Sciences between June 2014 and June 2017. Out of 34 cases of intercondylar fractures of humerus admitted during the period, 25 patients were selected for the study that satisfied our inclusion criteria. Three patients out of those selected could not be included in the study as one had cardiac issues pre-operatively, one refused surgery and one was lost to follow up.<strong></strong></p><p class="abstract"><strong>Results:</strong> Our study included 22 patients, 14 male and 8 female patients. Their average age was 41.4 years. The fractures were classified as per the AO classification. There were B1-3, B2-1, C1-6, C2-5, C3-7 fractures. Both compound and closed fractures were included. All the patients were operated by posterior olecranon Chevron osteotomy approach by a senior faculty member. Twenty two patients who satisfied our inclusion criteria were treated, followed up and the results analyzed using Cassabaum’s scale of elbow function we had 86% of excellent to good results. Our results are comparable with other similar studies.</p><p class="abstract"><strong>Conclusions:</strong> Posterior olecranon approach was found to be of most satisfactory approach by us. It allows good exposure of the joint and the ulnar nerve.</p>

SummaryIncomplete humeral condylar fracture was diagnosed by means of radiology, CT, scintigraphy, arthroscopy and bone biopsy in two English Pointer dogs. In both cases an acute thoracic limb lameness, unrelated to a known episode of major trauma, was observed. Incomplete humeral condylar fracture, mainly described in the Spaniel breeds, has been recently diagnosed in Labrador retrievers, Rottweiler, German Wachtel and other breeds. The pathogenesis of the condition is still unknown, but incomplete ossification of the humeral condyle and mechanical stress, alone or associated, have to be considered. However, our clinical and histopathological data lead us to believe that in Pointers, high performance dogs, the mechanical stress can assume a critical ethiopathogenetic role.

Aims Displaced fractures of the lateral condyle of the humerus are frequently managed surgically with the aim of avoiding nonunion, malunion, disturbances of growth and later arthritis. The ideal method of fixation is however not known, and treatment varies between surgeons and hospitals. The aim of this study was to compare the outcome of two well-established forms of surgical treatment, Kirschner wire (K-wire) and screw fixation. Patients and Methods A retrospective cohort study of children who underwent surgical treatment for a fracture of the lateral condyle of the humerus between January 2005 and December 2014 at two centres was undertaken. Pre, intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean age at the time of injury was 5.8 years (0 to 15) with a male:female patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture and the fracture was displaced by > 2 mm in 228 (68%). In all, 235 patients underwent K-wire fixation and 101 had screw fixation. Results There was a higher rate of nonunion with K-wire fixation (p = 0.02). There was no difference in Baumann’s angle, carrying angle or the rate of major complications between the two groups. No benefit was obtained by immobilizing the elbow for more than four weeks in either group. No short-term complications were seen when fixation crossed the lateral ossific nucleus. Conclusions Fixation of lateral condylar humeral fractures in children using either K-wires or screws gives satisfactory results. Proponents of both techniques may find justification of their methods in our data, but prospective, randomized trials with long-term follow-up are required to confirm the findings, which suggest a higher rate of nonunion with K-wire fixation.

Biomechanical Comparison

Summary Objective: To compare the biomechanical properties of simulated humeral condylar fractures reduced with one of two screw fixation methods: 3.0 mm headless compression screw (HCS) or 3.5 mm cortical bone screw (CBS) placed in lag fashion. Methods: Bilateral humeri were collected from nine canine cadavers. Standardized osteotomies were stabilized with 3.0 mm HCS in one limb and 3.5 mm CBS in the contralateral limb. Condylar fragments were loaded to walk, trot, and failure loads while measuring construct properties and condylar fragment motion. Results: The 3.5 mm CBS-stabilized constructs were 36% stiffer than 3.0 mm HCS-stabilized constructs, but differences were not apparent in quality of fracture reduction nor in yield loads, which exceeded expected physiological loads during rehabilitation. Small residual fragment displacements were not different between CBS and HCS screws. Small fragment rotation was not significantly different between screws, but was weakly correlated with moment arm length (R2 = 0.25). Clinical significance: A CBS screw placed in lag fashion provides stiffer fixation than an HCS screw, although both screws provide similar anatomical reduction and yield strength to condylar fracture fixation in adult canine humeri.
