Aims. The crucial role of the radial head in the stability of the elbow in terrible triad injury is acknowledged. This retrospective study aims to compare the results of resection of a severely comminuted radial head with or without prosthetic arthroplasty as part of the reconstruction for this injury. Patients and Methods. The outcome of radial head resection was compared with prosthetic arthroplasty in 29 and 15 patients with terrible triad injuries, respectively. There were ten female patients (34.5%) in the resection group and six female patients (40%) in the prosthesis group. The mean age was 40.7 years (. sd. 13.6) in the resection group and 36 years (. sd. 9.4) in the prosthesis group. The mean follow-up of the patients was 24.4 months (. sd. 12) in the resection group and 45.8 months (. sd. 6.8) in the prosthesis group. Outcome measures included visual analogue scale (VAS) for pain, Mayo Elbow Performance Score (MEPS), Disabilities of Arm, Shoulder and Hand (DASH) Score, and range of movement. Postoperative radiological complications were also recorded. Results. The mean ranges of extension, flexion, supination, and pronation were not significantly different between the two study groups (p = 0.75, p = 0.65, p = 0.82, and p = 0.68, respectively). The mean VAS score, DASH score, and MEPS of the two groups were also not statistically significantly different (p = 0.93, p = 0.19, and p = 0.32, respectively). At the final visit, the elbow was stable in all patients. No patient was found to have developed an Essex–Lopresti injury. Osteoarthritis grade I and II was observed in five and three patients of the resection group, respectively, and four and one patients of the arthroplasty group, respectively. Conclusion. The outcome of patients undergoing treatment for terrible triad injuries is similar whether the patient’s radial head was excised or replaced. Cite this article: Bone Joint J 2018;100-B:1499–505

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.

Fracture dislocations of the elbow are complex injuries that have a significant risk of long term instability and loss of function. The more severe injuries are fortunately rare and the published series are relatively small. This in turn means that there is less precise evidence and guidance as to the optimal treatment. With the improvements in the understanding of this injury we consider that the prognosis is not necessarily as poor as has been previously reported and we have attempted to quantify this in a prospective, single surgeon series with standard surgical and rehabilitation protocols using dedicated upper limb physiotherapists. Methods All patients presenting to the hospital with a terrible triad injury were seen by the senior author for assessment and treatment. Early surgical reconstruction was performed under general anaesthetic by the senior author. Radial head fractures were treated by fixation or prosthetic replacement. Ligament reconstruction or reinforcement was performed where needed. Following surgery early mobilisation was performed using dedicated upper limb physiotherapists. Information was collected prospectively recording function and stability. All patients were assessed with the Mayo clinic elbow score and the AAOS Disability of the Arm Shoulder and Hand score (DASH). Results Eleven patients were admitted with a terrible triad injury to their elbow. All were the result of an acute traumatic episode. Follow up was for a mean of 21 months and no patients were lost to follow up. All fractures had united and there were no cases of migration or failure of metal fixation devices. There were no cases of symptomatic instability and no patient had signs of instability when assessed at clinically. A mean flexion arc of 106 degrees was recorded (range 60–145) with a mean extension limit of 23 degrees (range 0–40). Pronation and supination arcs were recorded with a mean of 127 degrees of rotation (range 0–160). There were no reoperations for infection or instability amongst this group of patients. Mayo clinic performance index for the elbow produced a mean score of 91.5 with a range of 85–100 which equates to a good or excellent outcome for all patients. Conclusion We have demonstrated that with a combination of early surgical stabilisation of bony injuries and restoration of ligamentous stability coupled with a specialised rehabilitation programme can give excellent results in what was once felt to be a catastrophic injury

To review the outcome of compound injury to the shoulder in which traumatic anterior dislocation is associated with concomitant rotator cuff tear and injury to the brachial plexus.

22 patients initially treated at the Peripheral Nerve Injury Unit since 1994 were reviewed from notes, telephone and clinically (n=13) where possible. 19 men and 3 women of average age 53 years were treated with a minimum 3-year follow up. All patients underwent exploration of the brachial plexus and nerve repair where required (graft n=5). Patients had either proven large cuff tear (n=13) or avulsion fracture of greater tuberosity with cuff injury (n=9). 7 of 13 cuff injuries and 7 of 9 tuberosity fractures had been repaired. Nerve injury at exploration was to circumflex (n=20), supra-scapular (n=12), musculocutaneous (n=6), or at the cord level (Posterior n=10, Lateral n=7 Medial n=8). Outcome measures were Berman pain score, sensation, muscle power (MRC grade), abduction, functional scores (Mallett and DASH) and return to work. Statistical analysis used tests for non-parametric data.

22 patients had exploration of the plexus. Most patients did not have an isolated nerve lesion (n=4). Increased depth of nerve lesion correlated with poorer functional outcome. E.g. for circumflex nerve injury (n=18), conduction block (n=8) vs. axonotmesis or neurotmesis (n =10) functional range of movement as assessed by Mallett score was significantly different; Mann Whitney U test p=0.043. Late exploration of nerve tended to correlate with poor outcome, as did late repair of rotator cuff, but not to statistical significance.

Our explorations have shown the nerve injury sustained in these patients to be more widespread than expected. We believe early exploration is vital to give an accurate diagnosis and predict outcome for the nerve lesion. This is particularly important in the presence of associated cuff injury where early repair confers favourable outcome.

Don O’Donoghue (1950) described a particular acute injury of the knee in athletes (“also of high school age”) that he described as “an unhappy triad”. It consisted of: 1) rupture of the Medial Collateral Ligament (MCL), 2) damage to the Medial Meniscus (MM) and 3) rupture of the Anterior Cruciate Ligament (ACL)

We have reviewed the arthroscopic findings of 34 consecutive knees (ages 12 to 16 years) with complete rupture of the ACL. In 21 cases the injury was acute, and the remaining were chronic of had had more than one traumatic episode at the time of arthroscopy.

Out of the 34 cases, 26 had associated meniscal injuries: 4 MM; 14 Lateral Meniscus (LM) and 8 MM plus LM. Acute ACL injuries were associated mainly with LM damage (MM/LM: 1/5) whereas, in the chronic injuries, there were no such differences (MM/LM: 1/1). Out of the 21 acute LCA injuries there were 17 cases of acute rupture of the MCL.

Conclusions: 1- Contrary to what has been widely accepted, also in pre-adolescent and adolescent, Acute ACL ruptures are more frequently associated with LM damage that with MM tears. 2- Most injuries of the MM associated to ACL injuries (particularly “bucket handle” tears) are the result of a previously ACL unstable knee.

Aims. This study aimed to gather insights from elbow experts using the Delphi method to evaluate the influence of patient characteristics and fracture morphology on the choice between operative and nonoperative treatment for coronoid fractures. Methods. A three-round electronic (e-)modified Delphi survey study was performed between March and December 2023. A total of 55 elbow surgeons from Asia, Australia, Europe, and North America participated, with 48 completing all questionnaires (87%). The panellists evaluated the factors identified as important in literature for treatment decision-making, using a Likert scale ranging from "strongly influences me to recommend nonoperative treatment" (1) to "strongly influences me to recommend operative treatment" (5). Factors achieving Likert scores ≤ 2.0 or ≥ 4.0 were deemed influential for treatment recommendation. Stable consensus is defined as an agreement of ≥ 80% in the second and third rounds. Results. Of 68 factors considered important in the literature for treatment choice for coronoid fractures, 18 achieved a stable consensus to be influential. Influential factors with stable consensus that advocate for operative treatment were being a professional athlete, playing overhead sports, a history of subjective dislocation or subluxation during trauma, open fracture, crepitation with range of movement, > 2 mm opening during varus stress on radiological imaging, and having an anteromedial facet or basal coronoid fracture (O’Driscoll type 2 or 3). An anterolateral coronoid tip fracture ≤ 2 mm was the only influential factor with a stable consensus that advocates for nonoperative treatment. Most disagreement existed regarding the treatment for the terrible triad injury with an anterolateral coronoid tip fracture fragment ≤ 2 mm (O’Driscoll type 1 subtype 1). Conclusion. This study gives insights into areas of consensus among surveyed elbow surgeons in choosing between operative and nonoperative management of coronoid fractures. These findings should be used in conjunction with previous patient cohort studies when discussing treatment options with patients. Cite this article: Bone Joint J 2024;106-B(10):1150–1157

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

A prospective study of early operative treatment of unstable elbow dislocations using a surgical algorithm, we present the early results of nine such injuries including five terrible triads of the elbow and four elbows which redislocated in plaster. All except two were high energy injuries. The lateral collateral ligament complex was found to be avulsed proximally in all cases and was reattached using a bone anchor. The common extensor origin was also torn to a variable extent in all cases and was repaired end to end. In the terrible triads, the coronoid fracture as fixed with a transosseous suture and the radial head reconstructed or, in one case with gross comminution, replaced. In the four redislocations, full stability was only restored when the medial collateral ligament was also reattached. Mobilization without a hinged external fixator was allowed from day one, but the elbows were protected in a hinged splint in between exercise sessions. Patients were assessed for stability, ROM, and functional disability using the DASH score at an average of 12 months. No elbows redislocated post-operatively and no patients complained of instability. Mean extension was 18° (95% CI 7° – 28°), flexion 131° (124° – 137°), pronation 76° (56° – 96°), and supination 82° (75° – 90°). Mean DASH score was 14.6 (95% CI 0.7 – 28.5) though this result was skewed by one patient who developed RSD and had a DASH score of 67.2. This was however the only complication. Early operative intervention with reconstruction of unstable elbow dislocations, including the terrible triad, prevents the poor results which are commonly found following non-operative treatment of such injuries. An external fixator is not usually required in the acute setting

The June 2014 Trauma Roundup. 360 . looks at: BMP use increasing wound complication rates in trauma surgery; can we predict re-admission in trauma?; humeral bundle nailing; how best to treat high-angle femoral neck fractures?; hyperglycaemia and infection; simultaneous soft-tissue and bony repair in terrible triad injuries; metaphyseal malunion in the forearm leading to function restrictions; delayed fixation of the distal radius: not a bad option; and fasciotomies better with shoelaces

The April 2012 Trauma Roundup. 360 . looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries

The August 2012 Shoulder & Elbow Roundup. 360. looks at: platelet-rich fibrin matrix and the torn rotator cuff; ultrasound, trainees, and ducks out of water; the torn rotator cuff and conservative treatment; Bankart repair and subsequent degenerative change; proprioception after shoulder replacement; surgery for a terrible triad, with reasonable short-term results; and the WORC Index

Purpose: A prospective study of early operative treatment of unstable elbow dislocations using a surgical algorithm. Methods: We present the early results of nine such injuries including five terrible triads of the elbow and four elbows which redislocated in plaster. The avulsed lateral collateral ligament complex was reattached using a bone anchor in all cases. Coronoid and radial head fractures were fixed. In the four redislocations, full stability was only restored when the medial collateral ligament was reattached. Mobilization without a hinged fixator was allowed from day one. Patients were assessed for stability, ROM, and functional disability using the DASH score at an average of 13 months. Results: No elbows redislocated post-operatively and no patients complained of instability. Mean extension was 18° (95% CI 7° – 28°), flexion 131° (124° – 137°), pro-nation 76° (56° – 96°), supination 82° (75° – 90°). Mean DASH score was 11.0 (95% CI 3.5 – 18.6). Conclusion: Early reconstruction of unstable elbow dislocations, including the terrible triad, prevents the poor results which are commonly found following non-operative treatment of such injuries. An external fixator is not usually required in the acute setting

Heterotopic ossification (HO) is a well-known complication of traumatic elbow injuries. The reported rates of post-traumatic HO formation vary from less than 5% with simple elbow dislocations, to greater than 50% in complex fracture-dislocations. Previous studies have identified fracture-dislocations, delayed surgical intervention, and terrible triad injuries as risk factors for HO formation. There is, however, a paucity of literature regarding the accuracy of diagnosing post-traumatic elbow HO. Therefore, the purpose of our study was to determine the inter-rater reliability of HO diagnosis using standard radiographs of the elbow at 52 weeks post-injury, as well as to report on the rate of mature compared with immature HO. We hypothesized inter-rater reliability would be poor among raters for HO formation. Prospectively collected data from a large clinical trial was reviewed by three independent reviewers (one senior orthopedic resident, one senior radiology resident, and one expert upper extremity orthopedic surgeon). Each reviewer examined anonymized 52-week post-injury radiographs of the elbow and recorded: 1. the presence or absence of HO, 2. the location of HO, 3. the size of the HO (in cm, if present), and 4. the maturity of the HO formation. Maturity was defined by consensus prior to image review and defined as an area of well-defined cortical and medullary bone outside the cortical borders of the humerus, ulna, or radius. Immature lesions were defined as an area of punctate calcification with an ill-defined cloud-like density outside the cortical borders of the humerus, ulna or radius. Data were collected using a standardized online data collection form (CognizantMD, Toronto, ON, CA). Inter-rater reliability was calculated using Fleiss’ Kappa statistic and a multivariate logistic regression analysis was performed to identify risk factors for HO formation in general, as well as mature HO at 52 weeks post injury. Statistical analysis was performed using RStudio (version1.4, RStudio, Boston, MA, USA). A total of 79 radiographs at the 52-week follow-up were reviewed (54% male, mean age 50, age SD 14, 52% operatively treated). Inter-rater reliability using Fleiss’ Kappa was k= 0.571 (p = 0.0004) indicating moderate inter-rater reliability among the three reviewers. The rate of immature HO at 52 weeks was 56%. The multivariate logistic regression analysis identified male sex as a significant risk factor for HO development (OR 5.29, 1.55-20.59 CI, p = 0.011), but not for HO maturity at 52 weeks. Age, time to surgery, and operative intervention were not found to be significant predictors for either HO formation or maturity of the lesion in this cohort. Our study demonstrates moderate inter-rater reliability in determining the presence of HO at 52 weeks post-elbow injury. There was a high rate (56%) of immature HO at 52-week follow-up. We also report the finding of male sex as a significant risk factor for post traumatic HO development. Future research directions could include investigation into possible male predominance for traumatic HO formation, as well as improving inter-rater reliability through developing a standardized and validated classification system for reporting the radiographic features of HO formation around the elbow

Advancements in treating the unstable elbow. We will review and discuss the kinematics and biomechanics of the forearm, concentrating on the role of soft tissue structures and how they affect forearm and elbow function. During this session, we will review the latest techniques for treating the terrible triad, including solutions to complex injuries of the olecranon, coronoid, and radial head. Techniques presented will address fixation, reconstruction, and salvaging of complex unstable elbow injuries

Background. Acute anterior dislocation of the glenohumeral joint may be complicated by injury to neighboring structures. These injuries are best considered a spectrum of injury ranging from an isolated dislocation (unifocal injury), through injuries associated with either nerve or osteoligamentous injury (bifocal injury), to injuries where there is evidence of both nerve and osteoligamentous injury. The latter combination has previously been described as the “terrible triad,” although we prefer the term “trifocal,” recognizing that this is the more severe end of an injury spectrum and avoiding confusion with the terrible triad of the elbow. We evaluated the prevalence and risk factors for nerve and osteoligamentous injuries associated with an acute anterior glenohumeral dislocation in a large consecutive series of patients treated in our Unit. Materials and Methods. 3626 consecutive adults (mean age 48yrs) with primary traumatic anterior shoulder dislocation treated at our unit were included. All patients were interviewed and examined by an orthopaedic trauma surgeon and underwent radiological assessment within a week of injury. Where rotator cuff injury or radiologically-occult greater tuberosity fracture was suspected, urgent ultrasonography was used. Deficits in neurovascular function were assessed clinically, with electrophysiological testing reserved for equivocal cases. Results. Unifocal injuries occurred in 2228 (61.4%) of patients. There was a bimodal distribution in the prevalence of these injuries, with peaks in the 20–29 age cohort (34.4% patients) and after the age of 60 years (23.0% patients). Of the 1120 (30.9%) patients with bifocal dislocations, 920 (82.1%) patients had an associated osteotendinous injury and 200 (17.9%) patients had an associated nerve injury. Trifocal injuries occurred in 278 (7.7%) of cases. In bifocal and trifocal injuries, rotator cuff tears and fractures of the greater tuberosity or glenoid were the most frequent osteotendinous injuries. The axillary nerve was most frequently injured neurological structure. We were unable to elicit any significant statistical differences between bifocal and trifocal injuries with regards to patient demographics. However, when compared with unifocal injuries, bifocal or trifocal injuries were more likely to occur in older, female patients resulting from low energy falls (p<0.05). Conclusions. We present the largest series reporting the epidemiology of injury patterns related to traumatic anterior shoulder dislocation. Increased understanding and awareness of these injuries among clinicians will improve diagnosis and facilitate appropriate treatment

A particular pattern of complex instability of the elbow is “the terrible triad”, in which elbow dislocation is associated with fractures of the coronoid and radial head. Other frequent patterns are the variant of Monteggia lesions (Bado II) described by Jupiter which is characterized by ulnar fracture associated with fracture-dislocation of proximal radius, and the articular fracture of the distal humerus associated with elbow dislocation. The goal of treatment is to restore the primary stabilizers of the elbow such as the coronoid process, olecranon and both collateral ligaments by internal fixation and reconstruction of the ligaments. If elbow stability obtained at operation is unsatisfactory or internal fixation not enough stable, there an indication for applying a dynamic external fixator (DEF). The latter allows:. the articular congruence to be maintained and the ligaments to heal in adequate tension and position,. internal fixation and ligaments reconstruction to be protected, and. immediate joint motion to be carried out. From 2005 to 2008, we treated surgically 31 patients with complex instability of the elbow. DEF was applied in 38% of cases, namely 3 terrible triads, 5 fracture-dislocations of Monteggia and 4 articular fractures of the humerus associated with elbow dislocation. The mean age of patients was 44 years (range 30–74). All patients underwent ORIF, reconstruction of ligaments and dynamic external fixation. The OptiROM elbow fixator was used In 2 patients, the Orthofix fixator in 1 and the DJD fixator in 9. In all cases, active elbow motion was allowed without restrictions from the second postoperative day. Indomethacin was consistently administered for 5 weeks to prevent heterotopic ossifications. The DEF was removed after 6 weeks. The mean follow-up was 25 months (range 5–44 months). At last follow-up, the clinical results, evaluated according to the MEPS, were excellent in 10 patients (83%), who had had a fast recovery of range of motion (ROM). The elbow was painless in all patients and stable in all but 1. Moderate osteoarthrosis was found in 60% of cases. Complications included: 1 elbow stiffness, 1 pseudarthrosis of capitulum humeri and trochlea, 1 transitory radial nerve palsy, and 1 superficial pin tract infection. In conclusion, DEF is a helpful tool for treatment of complex elbow instability, particularly when stable internal fixation cannot be obtained or instability persists after ligaments reconstruction. However, DEF increases morbidity, and implies a longer operative time and prolonged exposure to radiation
