Shoulder instability, performance, and return to play in National Hockey League players

Management of the in-season athlete with an anterior shoulder dislocation

BACKGROUND

Management of the in-season athlete presenting with an anterior shoulder dislocation is a nuanced process that continues to be refined. Options and pathways between nonoperative and operative treatment have undergone many iterations over a century of orthopedic research and advancement. It requires an understanding of sport-specific demands and the individual athlete's goals. The orthopedic surgeon must have mastery of the natural history, treatment options, and outcomes of anterior shoulder dislocations. Balance of these factors is delicate and highly individualized for each athlete, and is why management of the in-season athlete with an anterior shoulder dislocation remains an art for the orthopedic surgeon.

MATERIALS AND METHODS

A narrative review of the literature regarding the in-season athlete with anterior shoulder dislocation was conducted of the PubMed, Embase, and Cochrane databases. The findings are summarized in this article.

RESULTS

Multiple studies have investigated management of the in-season athlete with anterior shoulder dislocation. Treatment is highly individualized for each athlete and their respective circumstances. Nonoperative treatment remains the only option for athletes that seek to return to play in the same season, however with a high risk of recurrence. Operative treatment has a track record of success in terms of returning to high level of play and lower recurrence, but would preclude a return to competition in the same season.

CONCLUSIONS

Management of the in-season athlete with anterior shoulder dislocation remains a challenging issue without consensus recommendation among shoulder surgeons. Much has been done to understand the pathology and delineate indications for nonoperative treatment and surgical management. Although recurrence and return to play rates have improved with each iteration, recurrent instability and revision surgery continue to occur at high rates. Therefore, additional work remains to optimize return to play as well as long-term outcomes for athletes.

Initial versus Subsequent Injury and Illness and Temporal Trends Among Professional Hockey Players

Background

Research is limited investigating injuries/illness incidence among National Hockey League (NHL) players. This study sought to establish injury/illness incidence, initial versus subsequent injury risk among NHL players, and determine temporal trends of injury and illness incidence.

Hypothesis

Variations in injury incidence by body region, and initial versus subsequent injury would be observed among positions.

Study Design

Retrospective cohort study.

Methods

Publicly available data were utilized. NHL players 18 years or older between 2007-2008 to 2018-2019 were included. Injury and illness was stratified by position and body segment. Incidence rate (IR), and initial versus subsequent injury and illness risk ratios were calculated. Temporal trends were reported.

Results

Nine thousand, seven-hundred and thirty four injuries and illnesses were recorded. Centers had the highest overall IR at 15.14 per 1000 athlete game exposures (AGEs) (95%CI:15.12-15.15) and were 1.4 times more likely to sustain a subsequent injury compared to other positions. The groin/hip/thigh was the most commonly injured body region with an IR of 1.14 per 1000 AGEs (95%CI:1.06-1.21), followed by the head/neck (0.72 per 1000 AGEs, 95%CI:0.66-0.78). Combined injury and illness IR peaked in 2009-2010 season at 12.01 (95%CI: 11.22-12.79). The groin/hip/thigh demonstrated peak incidence during the 2007-2008 season (2.53, 95%CI:2.17-2.90); head/neck demonstrated a peak incidence in 2010-2011 season (Overall: 1.03, 95%CI:0.81-1.26). Injuries reported as 'lower body' increased over time.

Conclusions

Positional differences were observed; centers demonstrated the highest overall IR, and subsequent injury risk. Injury by body region was similar to previous literature. Head/neck and concussion decreased over time supporting rule changes in body checking and visor wear. Clinicians should be aware that 'lower body' injuries increased over time; therefore, injuries to the groin/hip/thigh or knee are likely underreported.

Shoulder injuries in ice hockey players: Prevalence, common management, and return to play

Background

The sport of ice hockey has reached worldwide popularity, and it continues to grow. With this growth, however, there has also been an increase in the number of injuries related to the high-speed physical nature of the sport. Upper extremity related traumas and maladies are amongst the most commonly experienced injuries in this population of athletes. The objective of this narrative review is to appraise the current literary landscape as to the epidemiology, treatment, and return to play experienced with the most common upper extremity orthopedic injuries related to ice hockey play.

Methods

PubMed, Google Scholar, and OVID were searched individually using the filtered terms "shoulder", "injury", and "ice hockey". Articles that were published after 2000 were analyzed. Notably, the concepts of athlete sex, compete level, and post injury productivity were explored in detail.

Results

It is evident in the literature that upper extremity injury rates increased as level of play increased, were more common in males, and occurred more often during in-game situations. Acromioclavicular joint separations, shoulder instability, and clavicle fractures were amongst the most commonly cited ice hockey upper extremity injury presentations; acromioclavicular joint injuries were considered the most common upper extremity injury in ice hockey players. Return to play depends on injury type and severity. Overall, performance decreased upon initial return from injury.

Conclusion

Ultimately, further research needs to be conducted on shoulder related ice hockey injuries, their prevention, and the accurate management of specific presentations in order to ensure efficient and safe return to play.

Current concepts in anterior glenohumeral instability: diagnosis and treatment

The glenohumeral joint is the most dislocated articulation, accounting for more than 50% of all joint dislocations. The reason behind shoulder instability should be investigated in detail for successful management, and the treatment plan should be individualized for all patients. Several classification systems have been proposed for glenohumeral instability. A physical exam is mandatory no matter what classification system is used. When treating patients with anterior shoulder instability, surgeons need to be aware of the critical size of the bone loss, which is commonly seen. The glenoid track concept was clinically adopted, and the measurement of the glenoid track for surgical decision-making is recommended. Detailed assessment of existing soft tissue injury to the labrum, capsule, glenohumeral ligaments, and rotator cuff is also mandatory as their presence influences the surgical outcome. Rehabilitation, arthroscopic repair techniques, open Bankart procedure, capsular plication, remplissage, Latarjet technique, iliac crest, and other bone grafts offer the surgeon different treatment options according to the type of patient and the lesions to be treated. Three-dimensional (3D) technologies can help to evaluate glenoid and humeral defects. Patient-specific guides are low-cost surgical instruments and can be used in shoulder instability surgery. 3D printing will undoubtedly become an essential tool to achieve the best results in glenohumeral instability surgery.
