Congenital radial head dislocation with a progressive cubitus valgus: a case report
Congenital dislocation of the radial head is rare, although it is the most common congenital anomaly of the elbow. A concomitant progressive cubitus valgus of the elbow has not previously been described in literature. We describe a case of an 8-year-old girl with an unilateral congenital radial head dislocation with a progressive cubitus valgus of 35°, caused by a prematurely closing physis of the lateral humeral condyle. This might be caused by an increased pressure on the lateral physis by the anteriorly dislocated radial head. As no complaints or limitations were present, treatment was non-operative with clinical observation, with satisfactory results after a follow-up of 18 months. A concomitant progressive cubitus valgus can be present in patients with a congenital radial head dislocation. Non-operative treatment can provide satisfactory results
The incidence of associated fractures of the upper limb in fractures of the radial head
Radial head fractures are common injuries. In American publications, one-third of the patients with these fractures have been shown to have associated injuries. The aim of this retrospective study is to describe the epidemiology of radial head fractures and associated fractures of the ipsilateral upper extremity in a European population. This study describes the epidemiology of radial head and associated fractures of the upper extremity in a Dutch population by a retrospective radiographic review of all patients with a radial head fracture between 1 January 2006 and 1 July 2007. A total of 147 radial head fractures were diagnosed in 145 patients. The incidence in the general population was 2.5 per 10.000 per year. The average age was 45.9 (SD 17.3) years and male–female ratio was 2:3. The mean age of males was significantly lower (37.1, SD 14.2 years) than of women (53.9, SD 16.4 years). Associated fracture of the upper extremity was found in 10.2%. Coronoid fractures were most common (4.1%). Associated upper limb fractures in patients with a radial head fracture are common in the European population. It is of clinical importance to suspect associated lesions and to perform a thorough physical examination and additional radiological examination on demand
Magnetic resonance imaging findings in 46 elbows with a radial head fracture
Radial head fractures are common, and may be associated with other injuries of clinical importance. We present the results of a standard additional MRI scan for patients with a radial head fracture. PATIENTS AND METhods: 44 patients (mean age 47 years) with 46 radial head fractures underwent MRI. 17 elbows had a Mason type-I fracture, 23 a Mason type-II fracture, and 6 elbows had a Mason type-III fracture. Associated injuries were found in 35 elbows: 28 elbows had a lateral collateral ligament lesion, 18 had capitellar injury, 1 had a coronoid fracture, and 1 elbow had medial collateral ligament injury. The incidence of associated injuries with radial head fractures found with MRI was high. The clinical relevance should be investigate
Radial head fracture: a potentially complex injury
Na de overgang stijgt de kans op botontkalking (osteoporose). Maar hoe weet je of je als vrouw in de gevarenzone zit? Laurens Kaas pleit voor screening op basis van breuken van de radiuskop (het uiteinde van één van de botten in de onderarm). Hij ontdekte een duidelijke piek in het aantal vrouwen met zo’n breuk in de leeftijdscategorie 50 tot 60 jaar. Een dergelijke breuk zou kunnen wijzen op botontkalking. Kaas stelt daarom voor om bij vrouwen van boven de 50 met een radiuskopfractuur een botdichtheidsmeting te doen. Daarnaast keek hij naar begeleidende letsels bij radiuskopfracturen en naar classificatie en behandeling
The epidemiology of radial head fractures
Recent literature shows an increased mean age of female patients with radial head fractures compared with male patients with radial head fractures. However, data on epidemiology of radial head fractures and specifically in relation to age distribution and male-female ratios of radial head fracture are scarce. A retrospective database search was performed to identify all patients with a radial head fracture over a 3-year period. A total of 328 radial head fractures were diagnosed in 322 patients. The incidence was 2.8 per 10,000 inhabitants per year. The male-female ratio was 2:3. The mean age was 48.0 years (range, 14-88 years; SD, 14.8). The mean age of female patients (52.8 years) was significantly higher than that of male patients (40.5 years) (P = .001). As the age increases above 50 years, the number of female patients becomes significantly higher than the number of male patients (P = .001). An associated osseous injury was present in 40 patients (12.4%). Radial head fractures are common, and associated injuries are frequen
Treatment of Mason Type II Radial Head Fractures Without Associated Fractures or Elbow Dislocation: A Systematic Review
Purpose There is no consensus as to the best treatment of Mason type II fractures without concomitant elbow fractures or dislocation. The aim of this systematic review was to compare the results of operative and nonoperative treatment of these injuries. Methods We systematically screened the databases of PubMed, EMBASE, and Cochrane Library until September 2011 for studies on nonoperative or operative treatment of Mason type II fractures. We defined successful treatment as an excellent or good result according to the Broberg and Morrey score, Mayo Elbow Performance Score, or Radin score. Exclusion criteria were duration of follow-up of less than 6 months, an improperly described therapy or combination of therapies, skeletal immaturity, and articles written in languages other than English. Results Among 717 studies, 9 retrospective case series (level IV) describing 224 patients satisfied our inclusion criteria. Nonoperative treatment was successful in 114 of 142 patients (80%) pooled from the studies (42% to 96% success in individual studies). Open reduction and internal fixation was successful in 76 of 82 patients (93%) (81% to 100% success in individual studies). Conclusions Only a few studies with a low level of evidence address the treatment of isolated, displaced, partial articular fractures. There is a need for sufficiently powered randomized, controlled trial
Press-fit bipolar radial head arthroplasty, midterm results
Theoretical advantages of bipolar compared with monopolar radial head arthroplasty include better accommodation of radiocapitellar malalignment, reduction of capitellar abrasion, and reduction of stress at the bone-implant interfaces. Our purpose was to report the midterm results of press-fit bipolar radial head arthroplasty. Thirty patients were treated by press-fit bipolar radial head arthroplasty for acute fracture of the radial head, failed earlier treatment, or post-traumatic sequelae. Three patients were lost to follow-up. Results are presented for the remaining 27 patients. At mean follow-up of 48 months (range, 28-73), there had been 3 (11%) revisions. Two involved conversion to prosthetic radiocapitellar hemiarthroplasty for symptomatic capitellar abrasion; a third involved exchange of the articular component (ie, head) for instability. In all, the stems appeared well fixed. A prosthesis in a subluxed position accounted for the 1 (4%) additional radiologic failure. The average flexion-extension arc was 136° (range, 120°-145°), and the average pronation-supination arc was 138° (range, 70°-180°). According to the Mayo Elbow Performance Score, the combined excellent and good results accounted for 70%. The overall midterm outcome of this series of 30 press-fit bipolar radial head arthroplasties can be considered favorable. Although the revision rate was 11%, the stems were well fixed in all. There was 1 (4%) additional radiologic failure. We suggest considering a press-fit bipolar radial head prosthesis for acute comminuted radial head fractures with limited bone loss of the proximal radiu
The effect of trauma and patient related factors on radial head fractures and associated injuries in 440 patients
Radial head fractures are commonly interpreted as isolated injuries, and it is assumed that the energy transferred during trauma has its influence on the risk on associated ipsilateral upper limb injuries. However, relationships between Mason classification, mechanism of injury, and associated injuries have been reported only once before in a relatively small population. The purpose of this study was to define whether trauma mechanism and patient related factors are of influence on the type of radial head fracture and associated injuries to the ipsilateral upper limb in 440 patients. The radiographs and medical records of 440 patients that presented with a fracture of the radial head were retrospectively analyzed. The medical records of all patients were searched for (1) the trauma mechanism and (2) associated injuries of the ipsilateral upper limb. The mechanism of injury was classified as being low-energy trauma (LET) or high-energy trauma (HET). Associated injuries to the ipsilateral upper limb were present in 46 patients (11%). The mean age of patients with associated injuries (52 years) was significantly higher compared to patients without associated injuries (47 years) (P = 0.038), and female patients with a radial head fracture were older than males. Injury patterns were classified as LET in 266 patients (60%) and as HET in 174 patients. HETs were significantly more common in young men. Associated injuries were not significantly different distributed between HET versus LET (P = 0.82). Injuries concomitant to radial head fractures were present in 11% of patients and the risk for these associated injuries increases with age. Trauma mechanism did not have a significant influence on the risk of associated injuries. Complex elbow trauma in patients with a radial head fracture seems therefore to be suspected based on patient characteristics, rather than mechanism of injur
