Aims. The aim of this study was to evaluate the outcome of complex radial head fractures at mid-term follow-up, and determine whether open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA) should be recommended for surgical treatment. Methods. Patients who underwent surgery for complex radial head fractures (Mason type III, ≥ three fragments) were divided into two groups (ORIF and RHA) and propensity score matching was used to individually match patients based on patient characteristics. Ultimately, 84 patients were included in this study. After a mean follow-up of 4.1 years (2.0 to 9.5), patients were invited for clinical and radiological assessment. The Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire score were evaluated. Results. Patients treated with ORIF showed significantly better postoperative range of motion for flexion and extension (121.1° (SD 16.4°) vs 108.1° (SD 25.8°); p = 0.018). Postoperative functional scores also showed significantly better results in the ORIF group (MEPS 90.1 (SD 13.6) vs 78 (SD 20.5); p = 0.004). There was no significant difference between the groups in terms of the complication rate (RHA 23.8% (n = 10) vs ORIF 26.2% (n = 11)). Implant-related complications occurred in six cases (14.3%) in the RHA group and in five cases (11.9%) in the ORIF group. Conclusion. Irrespective of the patient’s age, sex, type of injury, or number of fracture fragments, ORIF of the radial head should be attempted initially, if a stable reconstruction can be achieved, as it seems to provide a superior postoperative outcome for the patient compared to primary RHA. If reconstruction is not feasible, RHA is still a viable alternative. In the surgical treatment of complex radial head fractures, reconstruction shows superior postoperative outcomes compared to RHA. Good postoperative results can be achieved even after failed reconstruction and conversion to secondary RHA. Therefore, we encourage surgeons to favour reconstruction of complex radial head fractures, regardless of injury type or number of fragments, as long as a stable fixation can be achieved.

Radial head fractures with fragment displacement should be reduced and fixed, when classified as Mason II type injuries. We describe a method of arthroscopic fixation which is performed as a day case trauma surgery, and compare the results with a more traditional fixation approach, in a case controlled manner. We prospectively reviewed six Mason II radial head fractures which were treated using an arthroscopic reduction and fixation technique. The technique allows the fracture to be mobilised, reduced, and anatomically fixed using headless screws. All arthroscopic surgeries were conducted as day-cases. We retrospectively collected age and sex matched cases of open reduction and fixation of Mason II fractures using headless screws. The arthroscopic cases required less analgesia, shorter hospital admissions, and had fewer complications. The averaged final range of follow-up, at 1 year post-operation was 15 to 140 degrees in the arthroscopic group and 35 to 120 degrees in the open group. The Mayo Elbow Performance Score was 95/100 and 90/100 respectively. No acute complications were noted in the arthroscopic group, and a radial nerve neuropraxia [n=1], superficial wound infection [n=1], and loose screw [n=1]. Two patients of the arthroscopic group required secondary motion gaining operations [n=1 arthroscopic anterior capsulectomy for a fixed flexion contracture of 35 degrees, and n=1 loss of supination requiring and arthroscopic radial scar excision]. Three patients in the open group required secondary surgery [n=2 arthroscopic anterior capsulectomy for fixed flexion deformities, and n=1 arthroscopic anterior capsulectomy for fixed flexion deformities, and n=1 arthroscopic radial head excision for prominent screws, loss of forearm rotation, and radiocapitellar arthrosis pain]. The technique of arthroscopic fixation of Mason II radial head fractures appears to be valid, with respect to anatomical restoration of the fracture, minimal hospital admission, reduction in analgesia requirement, fewer complications, and a decreased need for secondary surgery

Introduction. The majority of radial head fractures may be treated successfully by conservative means and they are often considered a benign injury. However, approximately 25% of Mason type II fractures will not have a good long term result. Pain and stiffness can be a problem and this may be a significant complaint in young active patients with pain at end range of motion. Methods. A retrospective review of a single surgeon series of 62 consecutive elbow arthroscopic arthrolyses performed in 62 patients between June 2006 and Sept 2009 was performed. Pre- and post-operative ranges of motion (ROM) were assessed and recorded along with the patient's DASH score. Patients were kept in overnight and splinted in extension. Splints were removed the following day and AROM exercises were commenced with the physiotherapist. Patients were reviewed and assessed at follow up. Results. The majority of patients were male with an average age of 37 years The majority of post-traumatic cases were Mason type II fractures, who had failed conservative treatment. A statistically significant improvement in ROM of was seen following surgery for trauma related stiffness compared to other aetiologies. A improvement was also noted in DASH scores. Conclusions. In this series of elbow arthroscopic arthrolyses performed for stiffness following radial head fracture the procedure was a safe and well tolerated with significant improvements seen post-operatively. This may be an effective method of treating patients with painful stiff elbows post radial head fracture

Aims. The purpose of this study was to evaluate the relationships between the degree of injury to the medial and lateral collateral ligaments (MCL and LCL) and associated fractures in patients with a posterolateral dislocation of the elbow, using CT and MRI. Methods. We retrospectively reviewed 64 patients who presented between March 2009 and March 2018 with a posterolateral dislocation of the elbow and who underwent CT and MRI. CT revealed fractures of the radial head, coronoid process, and medial and lateral humeral epicondyles. MRI was used to identify contusion of the bone and collateral ligament injuries by tear, partial or complete tear. Results. A total of 54 patients had a fracture; some had more than one. Radial head fractures were found in 25 patients and coronoid fractures in 42. Lateral and medial humeral epicondylar fractures were found in eight and six patients, respectively. Contusion of the capitellum was found in 43 patients and rupture of the LCL was seen in all patients (partial in eight and complete in 56), there was complete rupture of the MCL in 37 patients, partial rupture in 19 and eight had no evidence of rupture. The LCL tear did not significantly correlate with the presence of fracture, but the MCL rupture was complete in patients with a radial head fracture (p = 0.047) and there was significantly increased association in those without a coronoid fracture (p = 0.015). Conclusion. In posterolateral dislocation of the elbow, LCL ruptures are mostly complete, while the MCL exhibits various degrees of injury, which are significantly associated with the associated fractures.

Since 1986 we have treated 15 patients with fractures of the head of the radius limited to one or two fragments (Mason type II) by open reduction and internal fixation with the Fibrin Adhesive System. At a mean follow-up of over two years, all but one of the results were excellent. This method is recommended for the treatment of selected fractures of the radial head followed by early mobilisation.

Most fractures of the radial head are stable undisplaced or minimally displaced partial fractures without an associated fracture of the elbow or forearm or ligament injury, where stiffness following non-operative management is the primary concern. Displaced unstable fractures of the radial head are usually associated with other fractures or ligament injuries, and restoration of radiocapitellar contact by reconstruction or prosthetic replacement of the fractured head is necessary to prevent subluxation or dislocation of the elbow and forearm. In fractures with three or fewer fragments (two articular fragments and the neck) and little or no metaphyseal comminution, open reduction and internal fixation may give good results. However, fragmented unstable fractures of the radial head are prone to early failure of fixation and nonunion when fixed. Excision of the radial head is associated with good long-term results, but in patients with instability of the elbow or forearm, prosthetic replacement is preferred.

This review considers the characteristics of stable and unstable fractures of the radial head, as well as discussing the debatable aspects of management, in light of the current best evidence.

We measured the tension in the interosseous membrane in six cadaveric forearms using an in vitro forearm testing system with the native radial head, after excision of the radial head and after metallic radial head replacement. The tension almost doubled after excision of the radial head during simulated rotation of the forearm (p = 0.007). There was no significant difference in tension in the interosseous membrane between the native and radial head replacement states (p = 0.09). Maximal tension occurred in neutral rotation with both the native and the replaced radial head, but in pronation if the radial head was excised. Under an increasing axial load and with the forearm in a fixed position, the rate of increase in tension in the interosseous membrane was greater when the radial head was excised than for the native radial head or replacement states (p = 0.02). As there was no difference in tension between the native and radial head replacement states, a radial head replacement should provide a normal healing environment for the interosseous membrane after injury or following its reconstruction. Load sharing between the radius and ulna becomes normal after radial head Replacement. As excision of the radial head significantly increased the tension in the interosseous membrane it may potentially lead to its attritional failure over time.

Radial head fractures are among the most common fractures around the elbow. Radial head arthroplasty is one of the surgical treatment options after complex radial head fractures. This surgery is usually done under general anaesthesia. However, there is a recent anaesthetic technique - wide awake local anaesthesia no tourniquet (WALANT) - that has proven useful in different surgical settings, such as in distal radius or olecranon fractures. It allows a good haemostatic control without the use of a tourniquet and allows the patient to actively collaborate during the surgical procedure. Furthermore, there are no side effects or complications caused by the general anaesthesia and there's an earlier patient discharge. The authors present the case of a seventy-six-year-old woman who presented to the emergency department after a fall from standing height with direct trauma to the left elbow. The radiological examination revealed a complete intra-articular comminuted fracture of the radial head (Mason III). Clinical management: The patient was submitted to surgery with radial head arthroplasty, using WALANT. The surgery was successfully completed without pain. There were no intra or immediate post-operative complications and the patient was discharged on the same day. Six weeks after surgery, the patient had almost full range of motion and was very pleased with the functional outcome, with no limitations on her activities of daily living. The use of WALANT has been expanded beyond the hand and wrist surgery. It is a safe and simple option for patients at high risk of general anaesthesia, allowing similar surgical outcomes without the intraoperative and postoperative complications of general anaesthesia and permitting an earlier hospital discharge. Furthermore, it allows the patient to actively collaborate during the surgery, providing the surgeons the opportunity to evaluate active mobility and stability, permitting final corrections before closing the incision

Introduction. Virtual fracture clinics (VFC's) aim to reduce the number of outpatient appointments while improving the clinical effectiveness and patients experience through standardisation of treatment pathways. With 4.6% of ED admissions due to trauma the VFC prevents unnecessary face to face appointments providing a cost savings benefit to the NHS. Methods. This project demonstrates the importance of efficient VFC process in reducing the burden on the fracture clinics. We completed preformed a retrospective cross-sectional study, analysing two cycles in May (n=305) and September (n=332) 2021. We reviewed all VFC referrals during this time assessing the quality of the referral, if they went on to require a face to face follow up and who the referring health care professional was. Following the cycle in May we provided ongoing education to A&E staff before re-auditing in September. Results. Between the two cycles there was an average 19% improvement in quality of the referrals, significant reduction in number of inappropriate referrals for soft tissue knee and shoulder injuries from 15.1% (n=50) to 4.5% (n=15) following our intervention. There was an 8% increase in number of fracture clinic appointments to 74.4% (n=247), primarily due to an increase number of referrals from nurse practitioners. Radial head fractures were targeted as one group that were able to be successfully managed in VFC, despite this 64% (n=27) of patients were still seen in the outpatient department following VFC referral. Conclusion. Despite the decrease in the number of inappropriate referrals, and the increase in quality of referrals following our intervention. The percentage of VFC referrals in CAVUHB is still higher than other centres in with established VFCs in England. This possibly highlights the need for further education to emergency staff around describing what injuries are appropriate for referral, specifically soft tissue injuries and radial head fractures. In order to optimise the VFC process and provide further cost savings benefits while reducing the strain on fracture clinics

Aims. This study aimed to answer the following questions: do 3D-printed models lead to a more accurate recognition of the pattern of complex fractures of the elbow?; do 3D-printed models lead to a more reliable recognition of the pattern of these injuries?; and do junior surgeons benefit more from 3D-printed models than senior surgeons?. Methods. A total of 15 orthopaedic trauma surgeons (seven juniors, eight seniors) evaluated 20 complex elbow fractures for their overall pattern (i.e. varus posterior medial rotational injury, terrible triad injury, radial head fracture with posterolateral dislocation, anterior (trans-)olecranon fracture-dislocation, posterior (trans-)olecranon fracture-dislocation) and their specific characteristics. First, fractures were assessed based on radiographs and 2D and 3D CT scans; and in a subsequent round, one month later, with additional 3D-printed models. Diagnostic accuracy (acc) and inter-surgeon reliability (κ) were determined for each assessment. Results. Accuracy significantly improved with 3D-printed models for the whole group on pattern recognition (acc. 2D/3D. = 0.62 vs acc. 3Dprint. = 0.69; Δacc = 0.07 (95% confidence interval (CI) 0.00 to 0.14); p = 0.025). A significant improvement was also seen in reliability for pattern recognition with the additional 3D-printed models (κ. 2D/3D. = 0.41 (moderate) vs κ. 3Dprint. = 0.59 (moderate); Δκ = 0.18 (95% CI 0.14 to 0.22); p ≤ 0.001). Accuracy was comparable between junior and senior surgeons with the 3D-printed model (acc. junior. = 0.70 vs acc. senior. = 0.68; Δacc = -0.02 (95% CI -0.17 to 0.13); p = 0.904). Reliability was also comparable between junior and senior surgeons without the 3D-printed model (κ. junior. = 0.39 (fair) vs κ. senior. = 0.43 (moderate); Δκ = 0.03 (95% CI -0.03 to 0.10); p = 0.318). However, junior surgeons showed greater improvement regarding reliability than seniors with 3D-printed models (κ. junior. = 0.65 (substantial) vs κ. senior. = 0.54 (moderate); Δκ = 0.11 (95% CI 0.04 to 0.18); p = 0.002). Conclusion. The use of 3D-printed models significantly improved the accuracy and reliability of recognizing the pattern of complex fractures of the elbow. However, the current long printing time and non-reusable materials could limit the usefulness of 3D-printed models in clinical practice. They could be suitable as a reusable tool for teaching residents. Cite this article: Bone Joint J 2023;105-B(1):56–63

Radial head fractures are relatively common, representing approximately one-third of all elbow fractures. Outcomes are generally inversely proportional to the amount of force involved in the mechanism of injury, with simple fractures doing better than more comminuted ones. However, the prognosis for these fractures may also be influenced by associated injuries and patient-related factors (age, body index mass, gender, tobacco habit, etc.) The purpose of this study is to evaluate which factors will affect range of motion and function in partial radial head fractures. The hypothesis is that conservative treatment yields better outcomes. This retrospective comparative cohort study included 43 adult volunteers with partial radial head fracture, a minimum one-year follow up, separated into a surgical and non-surgical group. Risk factors were: associated injury, heterotopic ossification, worker's compensation, and proximal radio-ulnar joint implication. Outcomes included radiographic range of motion measurement, demographic data, and quality of life questionnaires (PREE, Q-DASH, MEPS). Mean follow up was 3.5 years (1–7 years). Thirty patients (70%) had associated injuries with decreased elbow extension (−11°, p=0.004) and total range of motion (−14°, p=0.002) compared to the other group. Heterotopic ossification was associated with decreased elbow flexion (−9°, p=0.001) and fractures involved the proximal radio-ulnar joint in 88% of patients. Only worker's compensation was associated with worse scores. There was no difference in terms of function and outcome between patients treated nonsurgically or surgically. We found that associated injuries, worker's compensation and the presence of heterotopic ossification were the only factors correlated with a worse prognosis in this cohort of patients. Given these results, the authors reiterate the importance of being vigilant to associated injuries

Aims. To evaluate the outcomes of terrible triad injuries (TTIs) in mid-term follow-up and determine whether surgical treatment of the radial head influences clinical and radiological outcomes. Methods. Follow-up assessment of 88 patients with TTI (48 women, 40 men; mean age 57 years (18 to 82)) was performed after a mean of 4.5 years (2.0 to 9.4). The Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and Disabilities of the Arm, Shoulder and Hand (DASH) score were evaluated. Radiographs of all patients were analyzed. Fracture types included 13 Mason type I, 16 type II, and 59 type III. Surgical treatment consisted of open reduction and internal fixation (ORIF) in all type II and reconstructable type III fractures, while radial head arthroplasty (RHA) was performed if reconstruction was not possible. Results. At follow-up the mean MEPS was 87.1 (20 to 100); mean OES, 36.9 (6 to 48); and mean DASH score, 18.6 (0 to 90). Mean movement was 118° (30° to 150°) for extension to flexion and 162° (90° to 180°) for pronation to supination. The overall reoperation rate was 24%, with nine ORIF, ten RHA, and two patients without treatment to the radial head needing surgical revision. When treated with RHA, Mason type III fractures exhibited significantly inferior outcomes. Suboptimal results were also identified in patients with degenerative or heterotopic changes on their latest radiograph. In contrast, more favourable outcomes were detected in patients with successful radial head reconstruction after Mason type III fractures. Conclusion. Using a standardized protocol, sufficient elbow stability and good outcomes can be achieved in most TTIs. Although some bias in treatment allocation, with more severe injuries assigned to RHA, cannot be completely omitted, treatment of radial head fractures may have an independent effect on outcome, as patients subjected to RHA showed significantly inferior results compared to those subjected to reconstruction, in terms of elbow function, incidence of arthrosis, and postoperative complications. As RHA showed no apparent advantage in Mason type III injuries between the two treatment groups, we recommend reconstruction, providing stable fixation can be achieved.

The evidence for treatment of acute complex radial head fractures with radial head replacement (RHR) predominantly comprises short to mid-term follow-up. This study describes the complications and long-term patient reported outcomes following RHR. From a single-centre trauma database we retrospectively identified 119 patients over a 16-year period who underwent primary RHR for an acute complex radial head fracture. We reviewed electronic records to document post-operative complications, including prosthesis revision and removal. Patients were contacted to confirm complications and long-term patient reported outcomes. The primary outcome measure was the QuickDash (QD). The mean age at injury was 50 years (16–94) and 63 (53%) were female. Most implants were uncemented ‘loose-fit’ monopolar prostheses; 86% (n=102) were metallic and 14% (n=17) silastic. Thirty patients (25%) required revision surgery (n=3) or prosthesis removal (n=27). Five patients underwent arthrolysis and there were four cases of infection. In the long-term, 80% (80/100; 19 deceased) were contacted at a mean of 12 years (7.5–23.5). The median QD was 6.8 (IQR, 16.8), the median EQ-5D was 0.8 (IQR, 0.6) and the median Oxford Elbow Score was 46 (IQR, 7). Overall satisfaction was high with a mean of 9.4/10 (2–10). There was no significant difference in any outcome measure for those patients requiring revision or removal surgery (all p>0.05). This is the largest series in the literature documenting the long-term patient reported outcome after RHR. Despite a quarter of patients requiring further surgery, RHR is supported by positive long-term results for the treatment of complex radial head fractures

Background. Comminuted radial head fractures are challenging to treat with open reduction and internal fixation. Complicating matters further, radial head fractures are often associated with other elbow fractures and soft tissue injuries. Radial head arthroplasty is a favorable technique for the treatment of radial head fractures. The purpose of this study was to evaluate the functional outcomes of radial head arthroplasty using Modular Pyrocarbon radial head prosthesis in patients with unreconstructible radial head fractures. Methods. This single surgeon, single centre study retrospectively reviewed the functional and radiological outcomes of 21 consecutive patients requiring radial head arthroplasty for unreconstructible radial head fractures between July 2003 and July 2009. Patients were at least one year post-op and completed a Short-Form 36 (SF-36) questionnaire, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the Mayo Elbow Performance Index (MEPI). These patients were independently physically examined and their post-operative radiographs were independently reviewed. Results. 21 patients (9 males and 12 females) were reviewed at a minimum of 12 months follow-up. The mean DASH score was 10.8 (0-34.1), the mean SF-36 physical score was 76.9 (35-96), the mean SF-36 mental score was 83.8 (60-94), and their MEPI score was 86.4 (70-100). Patients maintained 90% of their grip strength in their injured arm when compared to their un-injured arm and had 17. o. of fixed flexion in the affected arm. Radiologically, 14 cases had some degree of post-traumatic osteoarthritis, 12 cases had evidence of heterotrophic ossification, 5 had some evidence of periprosthetic lucency and 3 of our cases were radiologically but not functionally ‘overstuffed’. Conclusion. Radial Head Arthroplasty with Pyrocarbon Radial Head Prosthesis is a safe and effective option when treating unreconstructable comminuted radial head fractures yielding good functional and radiological outcomes and remains the treatment option of choice at our institution

Radial head fractures are common and mainly require a functional conservative treatment. About 20% of patients will present an unsatisfactory final functional result. There is, however, little data allowing us to predict which patients are at risk of bad evolve. This makes it difficult to optimize our therapeutic strategies in these patients. The aim of this study is to determine the personal and environmental factors that influence the functional prognosis of patients with a radial head fracture. We realized over a 1-year period a prospective observational longitudinal cohort study including 125 consecutive patients referred for a fracture of the radial head in a tertiary trauma center. We originally collected the factors believed to be prognostic indicators: age, sex, socioeconomic status, factors related to trauma or fracture, alcohol, tobacco, detection of depression scale, and financial compensation. A clinical and radiological follow-up took place at 6 weeks, 3 months, 6 months, and 1 year. The main functional measurement tool is the Mayo Elbow Performance Score (MEPS) and the Disabilities of the Arm, Shoulder and Hand (DASH). 123 patients were included in the study. 114 patients required nonsurgical management. 102 patients completed the 1-year follow-up for the main outcome (89 for the DASH score). Two patients required an unplanned surgery and were excluded from analyses. At 1 year, the average MEPS was 96.5 (range, 65–100) and 81% of subjects had an excellent result (MEPS ≥90). The most constant factor to predict an unsatisfactory functional outcome (MEPS <90 or DASH >17) is the presence of depressive symptoms at the initial time of the study (P = 0.03 and P = 0.0009, respectively). This factor is present throughout the follow-up. Other observed factors include a higher socioeconomic status (P = 0.009), the presence of financial compensation (P = 0.027), and a high-velocity trauma (P = 0.04). The severity of the fracture, advanced age, female sex, and the nature of the treatment does not influence the result at 1 year. No factor has been associated with a reduction in range of motion. Most of the radial head fractures heal successfully. We identified for the first time, with a valid tool, the presence of depressive symptoms at the time of the fracture as a significant factor for an unsatisfactory functional result. Early detection is simple and fast and would allow patients at risk to adopt complementary strategies to optimize the result

Background. Fractures of the radial head result from an axial force that causes impaction against the capitellum. Associated lesions of the capitellum in this pattern of injury have been previously reported in the orthopaedic literature as an uncommon occurrence. Methods. All patients presenting to the clinics of the senior surgeon between 1998-2008 with radial head fractures requiring surgery were included. Data collected included demographics (age, gender, side of injury), mechanism, timing of injury and injury type (Mason classification). Intraoperative findings including evidence of union, capitellar injury, associated joint dislocation, collateral ligament injury, and any other fractures around the elbow were documented. Results. We reviewed 109 consecutive patients presenting with radial head fractures. 67% of the patients were found to have the PLUCCAR lesion, a capitellar slither of cartilage impacted in the radial fracture. Of these, 76.9% of patients with a Mason I injury had a PLUCCAR lesion, 76.7% of patients with Mason II injury had a PLUCCAR lesion, and only 33.3% of patients with Mason III lesion had a PLUCCAR lesion. 13 patients had a pre-existing non-union, 84% of whom had a PLUCCAR lesion. 19 patients were found to have a malunion, 84% of whom were found to have the PLUCCAR lesion. Conclusion. Injury to the capitellum is commonly associated with radial head fracture. We term impaction of a capitellar fragment in the radius a PLUCCAR lesion. There is an increased incidence of this injury in less comminuted radial head fractures, and in patients presenting with non union or malunion of a radial head fracture

Radial head fractures are the most common fractures occurring around the elbow and are often associated with other fractures or soft tissue injuries in the elbow. The purpose of this study was to characterise the morphology and to evaluate the outcome of the surgical management of radial head fractures in complex elbow injuries. Nineteen patients with this pattern of injury underwent surgical treatment in our unit. In addition, seven patients had posterior dislocation of the elbow, 2 medial collateral ligament rupture, one capitellar fracture, 3 posterior Monteggia, 1 Essex-Lopresti lesion and 5 coronoid fracture plus posterior dislocation. Non comminuted radial head fractures were treated by open reduction and internal fixation or simple excision of small fragments. Patients with comminuted, displaced radial head fractures underwent radial head replacement. The average follow up was 44 months. Two patients developed post-traumatic elbow contractures, one elbow instability and 2 mild arthritis. Overall, according to the DASH Outcome Measure, the results were excellent in 12 patients, fair in 3 and poor in 4. In complex injuries of the elbow the characteristics of the radial head fracture and in particular the comminution, the fragment number, the displacement as well as the age of the patient should determine the appropriate surgical technique which will lead to satisfactory long-term results. Anatomical restoration and maintenance of elbow stability will allow early mobilisation of the elbow joint and should be the goals of surgical management

Background. Radial head fractures are the commonest fractures involving the elbow. The goals of treatment are to restore stability, preserve motion, and maintain the relative length of the radius. Fortunately, most simple uncomplicated fractures can be treated non-operatively. Choosing between fixation and radial head replacement for comminuted fractures remains difficult. Excision of radial head fractures is not an ideal option in unstable elbow injuries. The purpose of this systematic review was to search for and critically appraise articles directly comparing functional outcomes and complications for fixation (open reduction internal fixation, ORIF) versus arthroplasty for comminuted radial head fractures (Mason type 3) in adults. Method. A comprehensive search of Medline, Embase and Cochrane databases using specific search terms and limits was conducted. Strict eligibility criteria were applied to stringently screen resultant articles. Three comparative studies were identified and reviewed. Results. Three comparative studies were identified and reviewed: two studies found significantly better Broberg & Morrey functional scores after replacement compared with ORIF in Mason type 3 fractures. The third study found no significant differences in Mayo functional score or range of motion, but did find that grip strength was better after ORIF. Complication rates were too heterogenous for conclusion. Conclusion. Fixation with good reduction may be attempted in unstable Mason type 3 fractures, and arthroplasty may be considered if this is not possible. Further randomised comparative trials are required to clarify the decision-making between fixation and replacement. Functional outcomes and complications were conflicting in the studies included here. Ideally, treatment decision should take into account elbow stability and degree of comminution

Purpose. Limited information is available regarding the functional outcomes of radial head fractures managed with open reduction and internal fixation (ORIF). The purpose of this study was to determine the functional outcomes of radial head fractures treated with ORIF. Method. Fifty-two patients, with a mean age of 4412 years, who were treated with radial head ORIF were evaluated at a mean of 4.42.4 years. Thirty were isolated radial head fractures (Group A), 13 (Group B) were associated with a complex fracture-dislocation (terrible triad variants), and 5 (Group C) were associated with a proximal ulnar fracture (Monteggia/trans-olecranon variants). Fourty-four were partial articular fractures and 8 were complete articular fractures. Outcomes were assessed with physical and radiographic examination, and validated self-reported questionnaires. Results. The average PREE score (Patient Rated Elbow Evaluation) for Groups A, B, and C were 7.613.1, 12.313.4, and 108.5, respectively. The average MEPI (Mayo Elbow Performance Score) for Groups A, B, and C were 8913, 8511, and 918, respectively. For Groups A, B, and C respectively, the prevalence of radiographic radiocapitellar arthritis was 30%, 46%, and 20%. The average flexion/extension arc for Groups A, B, and C were 7 to 132, 6 to 134, and 10 to 132 respectively. Secondary surgery was performed in 17% of cases, most commonly for decreased motion. Three comminuted fractures failed ORIF and required conversion to radial head arthroplasty. Conclusion. Patients with radial head fractures, including those associated with complex fracture-dislocations, can achieve excellent functional outcomes with low self reported pain and disability when treated with ORIF, despite radiographic evidence of mild post-traumatic arthritis

Aim of the study: Mason type I radial head fractures are non-displaced fractures and are treated conservatively with early mobilization and excellent results. The aspiration of the accompanying haematoma is advocated by several authors in order to achieve an analgesic effect. The aim of this study was to investigate the effect of haematoma aspiration on intraarticular pressure and on pain relief after Mason I radial head fractures. Materials and Methods: 10 patients (6 men and 4 women, age 23–47 y), who presented in the emergency department after an elbow trauma. Following plain radiographs that showed a Mason I radial head fracture, the patients were subjected to haematoma paracentesis. Initially, the intraarticular pressure was measured by using the Stryker Intra-Compartmental Pressure Monitor System. Afterwards, aspiration of the haematoma was performed, followed by a new pressure measurement without moving the needle. Finally, a brachial-elbow-wrist back slab was placed and a questionnaire was completed, including among others pain evaluation before and after haematoma aspiration by using an analogue ten point pain scale. Results: The intraarticular elbow pressure prior to haematoma aspiration varied from 49 mmHg to 120 mmHg (mean 76.9 mmHg), while following aspiration it ranged from 9 mmHg to 25 mmHg (mean 16.7 mmHg). The mean quantity of the aspired blood was 3.45 ml (0.5 ml to 8.5 ml). Finally, the patients reported a pain decrease from 5.5 (4 to 8) before aspiration to 2.8 (1 to 4) after haematoma aspiration. Decrease for both pressure and pain was statistically significant (p< 0.001). Conclusion: The built of an intraarticular haematoma in the elbow joint following an undisplaced Mason I radial head fracture leads to a pronounced increase of the intraarticular pressure accompanied by intense pain for the patient. The aspiration of the haematoma results in an acute pressure decrease and an immediate patient relief
