Humeral and Glenoid Component Malposition in Revision Shoulder Arthroplasty: A Retrospective, Cross-sectional Study.

Background: The purpose of this study was to assess the incidence of glenoid and humeral component malposition in failed primary shoulder arthroplasty requiring revision. We hypothesized that glenoid and humeral component malposition would be a prevalent feature in cases requiring revision arthroplasty for primary anatomic TSA, primary RSA, and primary hemiarthroplasty procedures.

Methods: A retrospective cross-sectional study was performed focusing on identifying the incidence of malpositioned components in shoulder arthroplasty in quantitative and qualitative reviews.

Reduction of ischemic time using the pull-through technique for scapular free flap.

Purpose: Current scapular free flap (SFF) harvest in mandibular reconstruction often requires repositioning, hindering simultaneous harvest and resection and potentially increasing ischemic time. This study evaluated the efficacy of the pull-through technique (PTT) for SFF harvest, aiming to reduce ischemic time during mandibular segmental resection.

Methods: A retrospective analysis was conducted on 24 patients who underwent mandibular reconstruction using SFF at two maxillofacial surgery departments between January 2015 and May 2022.

Return-to-Play Outcomes in Elite Athletes After Cervical and Lumbar Motion Preservation Spine Surgery: A Systematic Review.

Study Design: Systematic review.

Objective: The primary purpose of this article was to survey the present literature and report on return-to-play (RTP) outcomes in elite athletes after undergoing motion preservation spinal surgery (MPSS).

Background: For elite performance, athletes require adequate mobility throughout the trunk, torso, and spine to achieve maximal force production.

The impact of bone marrow stimulation on arthroscopic rotator cuff repair for small to large rotator cuff tears: a randomized controlled trial.

Background: Bone marrow stimulation (BMS), a procedure involving the creation of multiple channels in the greater tuberosity, is often performed alongside arthroscopic rotator cuff repair (ARCR). This study evaluated the effect of BMS on clinical and structural outcomes following ARCR.

Method: This study involved 204 patients with small, medium, and large full-thickness rotator cuff tears.

Acute patellar dislocation: how skeletal maturity affects patterns of injury.

Objective: The main objective of this study was to understand the role of skeletal maturity in the different patterns of osteochondral and ligamentous injuries after an acute lateral patellar dislocation.

Materials And Methods: Two radiologists independently reviewed MRIs of 212 knees performed after an acute lateral patellar dislocation to evaluate the presence of high-grade patellar osteochondral injury, femoral osteochondral injury, and medial patellofemoral ligament injury. The association of skeletal maturity (indicated by a closed distal femoral physis), age, sex, and first-time versus recurrent dislocation with each of these various lesions was analyzed using Chi-square or T test, and multivariable logistic regression with estimation of odds ratios (OR).

Types and doses of anti-adhesive agents injected into subacromial space do not have an effect on the clinical and anatomical outcomes after arthroscopic rotator cuff repair.

Purpose: Joint stiffness after arthroscopic rotator cuff repair is a major concern for orthopaedic surgeons. Various antiadhesive agents are commonly administered after rotator cuff repair for its prevention. This study aimed to compare the outcomes among patients injected with different types and amounts of anti-adhesive agents after rotator cuff repair.

Returning to golf after rotator cuff repair.

Background: The prevalence of rotator cuff repair is increasing; however, no study has assessed patients who have returned to golf activity after arthroscopic rotator cuff repair.

Methods: The subjects of the survey were 633 patients who were at least two years postoperative after rotator cuff repair from January 2005 to December 2017. From August 2019 to October 2019, survey responses were collected via an online questionnaire or phone calls and a total of 197 patients were reviewed retrospectively to study about returning to golf after rotator cuff repair.

Fighting and Penalty Minutes Associated With Long-term Mortality Among National Hockey League Players, 1967 to 2022.

Importance: National Hockey League (NHL) players are exposed to frequent head trauma. The long-term consequences of repetitive brain injury, especially for players who frequently engage in fighting, remains unknown.

Objective: To investigate the mortality rates and causes of death among NHL enforcers with more career fights and penalty minutes as compared with matched controls.

Latarjet procedure for failed Bankart repair provides better stability and return to sports, but worse postoperative pain and external rotation limitations with more complications, compared to revision Bankart repair: a systematic review and meta-analysis.

Purpose: This study aimed to compare the clinical results of revision Bankart repair versus the Latarjet procedure for failed Bankart repair.

Methods: A literature search was performed in databases, such as Pubmed, Embase, and Scopus Library. The studies were appraised using the Methodological Index for Non-randomized Studies tool.

Trends in MR Arthrogram Utilization at a Tertiary Care Academic Center.

The purpose is to evaluate the trends in MR arthrogram utilization at a tertiary care academic institution and to determine if there are factors that can be implicated in the utilization trends. Number of MR arthrograms of the shoulder, hip, and elbow from 2013-2020 at our institution were identified (n = 1882). Patient demographics including age, sex, sports participation, history of prior surgery, and physician referral were obtained.

Superior capsular reconstruction using hybrid graft for irreparable massive rotator cuff tear.

Purpose: To evaluate the clinical and radiological outcomes of arthroscopic superior capsular reconstruction (SCR) using hybrid grafts composed of tensor fascia lata autografts and human dermal allografts.

Methods: This study included 30 patients with chronic irreparable posterosuperior rotator cuff tears (RCTs) who underwent arthroscopic SCR using a hybrid graft composed of tensor fascia lata autograft and human dermal allograft. Clinical outcomes were evaluated using the pain visual analogue scale score, shoulder range of motion, American Shoulder and Elbow Surgeons score, constant score, University of California-Los Angeles score, and simple shoulder test score preoperatively and at least 2 years after surgery.

Injuries to Ice Hockey Referees and Linesmen: A Survey of International Ice Hockey Federation Officials.

Background: Ice hockey referees and linesmen are at risk for musculoskeletal injuries because of the lack of protective equipment and contact with players, sticks, pucks, the ice surface and boards.

Fighting in professional ice hockey: it's time for a change.

Ice hockey has long been defined by a level of violence not seen in other sports. The rough-and-tough vigilante nature of the game was often employed as a method of enticing fans. Play in the National Hockey League (NHL) evolved throughout the 20 century as the rules governing it did.

The Impact of the Instigator Rule on Fighting in the National Hockey League.

Background: Fighting is often considered an essential part of professional hockey. Increased ticket sales, a means to self-regulate other dangerous gameplay, and helping teams win are a few of the reasons that fighting advocates provide for retaining fighting in the NHL. However, fighting trends have changed over the past 50 years.

Background: Many in-season athletes choose to delay or avoid surgery in order to continue playing and avoid downtime such as missed games or seasons.

Purpose: To learn about the attitudes toward the injury and treatment of in-season shoulder instability in competitive athletes who have suffered a shoulder dislocation.

Study Design: Cross-sectional study; Level of evidence, 3.

Rotator cuff retear after repair surgery: comparison between experienced and inexperienced surgeons.

Background: We hypothesized in this study that the characteristics of retear cases vary according to surgeon volume and that surgical outcomes differ between primary and revision arthroscopic rotator cuff repair (revisional ARCR).

Methods: Surgeons performing more than 12 rotator cuff repairs (RCRs) per year were defined as high-volume surgeons, and those performing fewer than 12 RCRs were considered low-volume surgeons. Of the 47 patients who underwent revisional ARCR at our clinic enrolled in this study, 21 cases were treated by high-volume surgeons and 26 cases by low-volume surgeons.
