Review
BACKGROUND
There is no consensus regarding the management of posterior cruciate ligament (PCL) avulsion fractures and the expected outcomes after treatment.
PURPOSE
To systematically review clinical outcomes and complications after management of tibial-sided avulsion fractures of the PCL.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
A literature search of Scopus, PubMed, Medline, and the Cochrane Central Register for Controlled Trials was performed in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included were studies with evidence levels 1 to 4 that reported clinical outcomes after treatment of PCL tibial-sided avulsion fractures in humans. The quality of the included studies was performed using the Methodological Index for Non-Randomized Studies (MINORS) criteria. A meta-analysis was performed for patient-reported outcome measures using random-effects modeling with 95% CIs.
RESULTS
A total of 58 studies published between 1999 and 2022 were identified. The mean MINORS score was 9.90 ± 4.12, indicating overall low-quality evidence with high risk of bias. The studies comprised 1440 patients (mean age, 32.59 ± 5.69 years; 75.2% males) with a mean follow-up of 26.9 ± 19.6 months (range, 5.3-126 months). Most patients were treated with open surgery (63.6%), followed by arthroscopic surgery (29.7%) and nonoperative treatment (6.7%). All patients reported significant posttreatment improvement in both subjective and objective outcomes ( < .05 for all). Arthroscopic surgery was associated with lower postoperative posterior tibial translation compared with open surgery (range, 0.6-3.2 vs 1.7-3.1 mm), greater preoperative to postoperative improvement in Lysholm score (54.6 vs 48.8; < .0001), higher postoperative Tegner score (6.64 ± 1.03 vs 6.14 ± 2.29; = .0448), and a higher rate of return to sport (100% vs 89.5%; = .009). Nonoperative management was associated with a significantly lower fracture union rate (87% vs 99.1%; < .0001) and greater postoperative side-to-side posterior translation (4.9 ± 4.3 mm) when compared with operative management.
CONCLUSION
Although nonoperative and surgical management of PCL tibial avulsion fractures resulted in high rates of fracture union and improvement in functional outcome scores and a low incidence of complications, nonoperative treatment yielded a high side-to-side posterior displacement (>4 mm) with a lower rate of fracture union compared to surgical treatment.

Review
INTRODUCTION
Tibial eminentia avulsion fracture is the paediatric equivalent to a midsubstance anterior cruciate ligament injury. It is most common between the ages of 8 and 19 years of age. The incidence is three per 100,000 per year. We explored the clinical evaluation and classification of the fracture, indications for and methods of surgery and the possible sequelae.
METHODS
We performed a systematic search in the PubMed database and retrieved 127 articles. A total of 16 articles met the defined inclusion criteria and were reviewed. Only studies on adolescents were included.
RESULTS
No prospective studies were found. The Meyers & McKeever and Zaricznyj classifications were commonly used, also when evaluating fractures for surgery. X-ray in three views is often sufficient to establish a diagnosis, but computed topographies can be necessary to further evaluate the type of fracture. There is disagreement as to whether a type II-fracture needs surgery. The method of fixation varies greatly between different kinds of suture techniques and screw fixations, but arthroscopic surgery is preferred in the most recent literature. Whether to cross the physis when fixating the fracture is also a matter of dis-agreement, but there is a lack of literature on the subject. All authors describe low rates of subjective sequelae.
CONCLUSION
Arthroscopic surgery is less invasive and allows for earlier mobilisation than other techniques. Pull-out suture seems to be a recommendable technique. There is a lack of literature on transphyseal fixation and a need for prospective studies evaluating the many different surgical techniques described and the indications for surgery.

Review
BACKGROUND
Although fracture of the coracoid process (CF) used to be considered rare, it is now more commonly encountered due to increased awareness and advances in imaging methods. This review aimed to analyze reported cases of CF to determine its mechanism and appropriate treatment.
METHODS
PubMed and Scopus were searched using the terms "scapula fracture" and "coracoid fracture." The inclusion criteria were English full-text articles concerning CF that described patient characteristics with appropriate images. The exclusion criteria included cases without appropriate images and those with physeal injury or nonunion. Citation tracking was conducted to find additional articles and notable full-text articles in other languages. Fractures were mainly classified using Ogawa's classification.
RESULTS
Ninety-seven studies were identified, including 197 patients (131 men, 33 women; average age 37.0±16.9 years). CF was classified as type I in 77%, type II in 19%, and avulsion fracture at the angle in 5%. Concurrent shoulder girdle injuries included acromioclavicular injury in 33%, clavicular fracture in 17%, acromion or lateral scapular spine fracture in 15%, and anterior shoulder instability in 11%. Among patients with type I CF, 69% had multiple disruptions of the superior shoulder suspensory complex. Conservative treatment was applied in 71% of isolated type I CF, while surgical treatment was applied in 76% of type I CF with multiple disruptions. Although the evaluation methods varied, 60% of patients were followed up for more than 6 months, and the outcomes were generally satisfactory for both conservative and surgical treatments.
CONCLUSION
CF occurred commonly in the age group with higher social activity. The most common fracture type was type I. The possible mechanism of CF is violent traction of the attached muscles, except for avulsion fracture at the angle. Type I CF with multiple disruptions of the superior shoulder suspensory complex requires surgical treatment, whereas conservative care is recommended for isolated type I and type II CFs.

Satisfactory clinical outcome of operative and non-operative treatment of avulsion fracture of the hamstring origin with treatment selection based on extent of displacement: a systematic review.
PURPOSE
To compare outcome of operative and non-operative treatment of avulsion fractures of the hamstring origin, with minor (< 1.5 cm) and major (≥ 1.5 cm) displacement, and early (≤ 4 weeks) and delayed (> 4 weeks) surgery.
METHODS
A systematic literature search was performed using PubMed, Cochrane, Embase, CINAHL and SPORTDiscus. A quality assessment was performed using the Physiotherapy Evidence Database (PEDro) scale.
RESULTS
Eight studies with 90 patients (mean age: 16 years) were included. All studies had low methodological quality (PEDro score ≤ 5). Operative treatment yielded a return to preinjury activity rate (RTPA) of 87% (95% CI: 68-95), return to sports (RTS) rate of 100% (95% CI: 82-100), Harris hip score (HHS) of 99 (range 96-100) and a University of California Los Angeles activity scale (UCLA) score of 100%. Non-operative treatment yielded a RTPA rate of 100% (95% CI:68-100), RTS rate of 86% (95% CI: 69-94), HHS score of 99 (range 96-100), and non-union rate of 18% (95% CI: 9-34). All patients with minor displacement were treated non-operatively (RTPA: 100% [95% CI: 21-100], RTS: 100% [95% CI: 51-100]). For major displacement, operative treatment led to RTPA and RTS rates of 86% (95% CI: 65-95) and 100% (95% CI: 84-100), and 0% (0/1, 95% CI: 0-79) and 100% (95% CI: 51-100) for non-operative treatment. Early surgery yielded RTPA and RTS rates of 100% (95% CI: 34-100 & 57-100) compared to 100 (95% CI: 72-100) and 90% (95% CI: 60-98) for delayed repair.
CONCLUSION
All included studies have high risk of bias. There is only low level of evidence with a limited number of included patients to compare outcome of operative and non-operative treatment. Overall outcome was satisfactory. There is a treatment selection phenomenon based on displacement, with acceptable outcome in both groups. There is insufficient data to draw conclusions regarding timing of surgery.

Orthopaedic Journal of Sports Medicine May 2022Arm wrestling is a popular sport in which various injuries have occurred, even in children. (Review)
Review
BACKGROUND
Arm wrestling is a popular sport in which various injuries have occurred, even in children.
PURPOSE
To analyze reported fracture-separation of the medial humeral epicondyle (MHE) caused by arm wrestling to determine its mechanism and provide a current overview.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
The PubMed and Web of Science databases were searched using the terms "arm wrestling" and "humeral fracture" or "medial humeral epicondyle fracture"; and "sports" and "humeral fracture" or "medial humeral epicondyle fracture," following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The inclusion criteria were English full-text articles on arm wrestling-induced MHE fracture that described patient characteristics and presented appropriate images. Studies with a lack of appropriate images or detailed description of the injury situation were excluded. The patient characteristics were evaluated, and the ratios of treatment selection and outcomes were evaluated using the chi-square test.
RESULTS
Included were 27 studies with a total of 68 patients, all boys with a mean age of 14.6 ± 1.24 years (based on n = 65, with 3 patients excluded from this calculation as no definitive age was provided). Boys aged 14 to 15 years accounted for 72% (49/68) of the cases. Fracture occurred suddenly during arm wrestling in 63 boys, while the other 5 boys experienced antecedent medial elbow pain. The match status at the time of injury, provided for 46 patients, was varied. In 31 boys with known match details, injury occurred when a participant suddenly added more force to change the match status. Eight patients displayed anterior and/or proximal displacement of the MHE fragment. Treatment was nonoperative in 25 patients and operative in 38 patients (n = 63, excluding 5 unknown patients). In 35 patients followed up for ≥3 months (mean, 17.6 ± 12.3 months), outcomes were not significantly different between the operative and nonoperative groups.
CONCLUSION
MHE fracture-separation caused by arm wrestling occurred mostly in boys aged 14 to 15 years regardless of the match status. The likely direct cause is forceful traction of the attached flexor-pronator muscles. A relative mechanical imbalance during adolescence may be an underlying cause. A sudden change from concentric to eccentric contraction of the flexor-pronator muscles increases the likelihood of fracture occurrence.

Review
BACKGROUND
The terrible triad of the elbow (TTE) is a complex injury consisting of simultaneous elbow dislocation or subluxation, radial head fracture, and coronoid fracture. During the initial assessment of a TTE, the typical severity of presenting pain, swelling, and limited range of motion may limit the ability to perform a thorough physical examination and thus divert a clinician's attention away from additional injuries to the ipsilateral upper extremity. Therefore, the purpose of this study was to review the literature for reported cases of concomitant ipsilateral upper extremity injuries associated with a TTE and discuss various strategies to increase clinician awareness to avoid underdiagnosis and missed diagnoses.
METHODS
A systematic review of five databases in four languages (English, Spanish, French, and Portuguese), from inception to May 2021, was conducted. Articles describing a TTE with a concomitant osseous, chondral, ligamentous, or musculotendinous injury occurring on the ipsilateral upper extremity were included. The patients were divided into two groups, those presenting with a classic TTE and concomitant ipsilateral upper extremity injury (group 1) and those in whom a TTE variant was described (group 2). A TTE variant was defined as a combination of osseous and/or chondral injuries to the elbow other than the classic description of TTE, in which at least two of the three classical elements of a TTE (elbow dislocation, coronoid fracture, and radial head fracture) were present in addition to other unique elbow osteoarticular injury.
RESULTS
Nineteen articles met inclusion criteria and were further analyzed. A total of 27 patients were analyzed, 23 from group 1 and 4 from group 2. Overall, 33 concomitant injuries were documented in group 1, the most common being an olecranon fracture (27.3%), followed by Essex-Lopresti injury, triceps tendon avulsion, and carpal fracture-dislocation with 4 (12.1%) cases each. Group 2 had four patients, all of whom presented with a unique variant of the classically described TTE.
CONCLUSION
Despite a characteristic radiographic appearance of the classic TTE, additional injuries of the ipsilateral extremity or variants of the classic TTE may be easily missed, especially in cases resulting from high-energy mechanisms of injury. By analyzing the available data on associated injuries and variants that may occur with a TTE, we hope to increase awareness so that clinicians may recognize these less common but more complex injury patterns.

Review
Functional Outcomes and Subsequent Surgical Procedures After Arthroscopic Suture Versus Screw Fixation for ACL Tibial Avulsion Fractures: A Systematic Review and Meta-analysis.
BACKGROUND
Although arthroscopic screw fixation and suture fixation are mainstream interventions for displaced anterior cruciate ligament avulsion fractures of the tibia, the differences in clinical outcomes between them remain inconclusive.
PURPOSE
To conduct a meta-analysis comparing the clinical and functional outcomes between arthroscopic screw fixation and suture fixation for tibial avulsion fractures.
STUDY DESIGN
Systematic review; Level of evidence, 3.
METHODS
A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and using the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases. Inclusion criteria were English-language articles that compared functional outcomes after screw fixation versus suture fixation for tibial avulsion fractures and had at least 1-year follow-up. Relevant data were extracted and analyzed statistically using the Mantel-Haenszel method and variance-weighted means. Random-effects models were used to generate pooled relative risk (RR) estimates with confidence intervals (CIs).
RESULTS
Of 1395 articles initially identified, we included 5 studies with 184 patients (91 patients with screw fixations and 93 patients with suture fixations). The pooled results indicated similar postoperative outcomes for screw fixation and suture fixation: Lysholm score (mean difference [MD], -0.32 [95% CI, -6.08 to 5.44]; = .91), proportion of International Knee Documentation Committee score grade A (74% vs 74%; RR, 0.63 [95% CI, 0.10-3.95]; = .63), Tegner score (MD, 0.10 [95% CI: -1.73 to 1.92]; = .92), and Lachman test results (stable knee joint, 82% vs 82%; RR, 0.99; 95% CI: 0.85-1.16; = .90). Patients in the screw fixation group had a significantly higher overall subsequent surgery rate (46% vs 19%; RR, 2.33; 95% CI,1.51-3.60; = .0001) and implant removal rate (44% vs 3%; RR, 8.52; 95% CI, 3.58-20.29; < .00001) compared with those in the suture fixation group. Nonimplant-related subsequent surgery rates were similar for the 2 groups.
CONCLUSION
The findings indicated a higher risk of subsequent surgery (RR, 2.33) and implant removal (RR, 8.52) after screw fixation when compared with suture fixation for tibial avulsion fractures. However, there were no significant differences in clinical outcome scores between the 2 techniques.

Avulsion fractures of the pelvis and hip region are typical injuries in adolescent athletes. Avulsion sites include the muscle tendon origin or insertion, and treating these injuries surgically or conservatively remains a debated issue. The main goals of this review were to assess and summarize injury types and sites, treatment-related clinical outcomes, and return to sport for adolescent patients with a pelvis avulsion fracture and to provide support for making treatment decisions. The PubMed database was searched in November 2021 to identify all published articles from 2000 to 2021 that reported the outcome and return to sport after conservative or surgical treatment. Eighteen studies with 453 patients were included in this review. The age range was 13.6-16.8 years. The most common injury site the was anterior superior iliac spine (37%), followed by the anterior inferior iliac spine (31%), ischial tuberosity (14%), lesser trochanter (9%), iliac crest (8%), and superior corner of the pubic symphysis (1%). Overall complications were lower in the surgical group compared to the conservative group. The rate of return to pre-injury activity level was greater in patients who underwent surgical treatment ( < 0.05). In conclusion, surgery is preferred for major dislocation and fragment size, providing a better return-to-sport rate and decreasing the risk of complications.

Review
INTRODUCTION
Arthroscopy procedures are the gold standard for the management of tibial spine avulsion. This review evaluates and compares different arthroscopic treatment options for tibial spine fractures.
SOURCE OF DATA
PubMed, Medline, Ovid, Google Scholar and Embase databases were systematically searched with no limit regarding the year of publication.
AREAS OF AGREEMENT
An arthroscopic approach compared with arthrotomy reduces complications such as soft-tissue lesions, post-operative pain and length of hospitalization.
AREAS OF CONTROVERSY
The use of suture techniques, compared to cannulated screw technique, avoids a second surgery for removal of the screws, but requires longer immobilization and partial weight bearing.
GROWING POINTS
Clinical outcomes and radiographic results do not seem to differ in relation to the chosen method of fixation.
AREAS TIMELY FOR DEVELOPING RESEARCH
Further studies are needed to produce clear guidelines to define the best choice in terms of clinical outcomes, function and complications.

Review
BACKGROUND
Fractures of the anteromedial facet (AMF) of the coronoid process are caused by a varus posteromedial rotational injury force, leading to instability in the ulnohumeral joint. AMF fractures are usually accompanied by avulsion of the lateral ulnar collateral ligament (LUCL). O'Driscoll's description and classification of AMF coronoid fractures has increased awareness and interest in this injury, but the optimal treatment has yet to be decided.
METHODS
We systematically reviewed the available literature searching electronic databases, MEDLINE using the PubMed interface and Embase. The primary objective was to determine outcome scores but also complication and revision rates depending on the fracture and its therapy in order to gain a more comprehensive picture. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were applied.
RESULTS
Initially, 304 publications were identified. Finally, 10 studies were left for inclusion, all of them retrospective in design, comprising 128 patients; the majority of them were male (75.7%). A total of 114 patients (89.1%) were treated surgically and 14 patients (10.9%) were treated conservatively. Among the surgically treated patients, 70.2% were treated with LUCL refixation. The average Mayo Elbow Performance Score of the surgically treated patients was 91.5 points. The average Mayo Elbow Performance Score of the conservatively treated patients was 91.4 points. A total of 10 patients (7.8%) required reoperation.
CONCLUSION
Surgery of AMF fractures leads to a satisfactory functional outcome in the vast majority of patients independent of the subtype. An algorithm for LUCL fixation is still pending. Conservative treatment may be considered under strict preconditions, especially for nondisplaced subtype 1 and 2 fractures, as these fractures show satisfactory functional outcomes when treated nonoperatively.
