BACKGROUND: Locking plate fixation appears to be a standard treatment for proximal humeral fracture. Different locking plate designs might result in different radiographic and functional outcomes. The original version of the Proximal Humeral Internal Locking System (PHILOS; DePuy Synthes, Warsaw, IN, USA) occupied the largest volume of the humeral head by screw distribution, whereas the Zimmer Periarticular Locking Plate (ZPLP) system (Zimmer Biomet, Warsaw, IN, USA) occupied the smallest...

BACKGROUND: Long-term radiographic arthritis has been commonly reported after radial head excision. Concern over radial head arthroplasty may arise in certain situations including capitellar arthritis, radiocapitellar malalignment, and in young and active patients. We hypothesized that radial head excision increases coronoid contact pressures, which may at least be partially reduced by radiocapitellar Achilles tendon disc arthroplasty. METHODS: Coronoid and capitellar contact pressure was measured on 6 human cadaveric elbows on a custom-designed gravity-valgus simulator under passive flexion from 0° to 90°...

BACKGROUND: Comminuted fractures of the proximal ulna remain a great challenge in orthopedic surgery. The purpose of this study was to report the outcomes of comminuted proximal ulna fractures treated with a new construct type-anatomically preformed polyaxial locking compression plates. METHODS: Between 2013 and 2016, 46 patients with isolated comminuted fractures were treated with a 2.7-/3.5-mm VA-LCP Olecranon Plate (Synthes, Umkirch, Germany). Of these, 44 were available for an assessment after a mean follow-up period of 2...

BACKGROUND: Acromioclavicular (AC) joint (ACJ) pathology is a common cause of shoulder dysfunction, and treatment recommendations vary. When the efficacy of treatment is evaluated, the ability to measure outcomes specific to the population is essential. The aim of the current research was to develop and validate a specific ACJ questionnaire. METHODS: Items for the "Specific AC Score" (SACS) were generated through the use of an expert panel, existing questionnaires, and patient feedback...

BACKGROUND: Acromial stress fractures following reverse shoulder arthroplasty have been increasingly studied because of potential functional impairment caused by this complication. The purpose of this study was to evaluate and compare different plating techniques for a type III acromial fracture (also referred to as "scapular spine fracture") in a biomechanical setting with special regard to primary stability and modes of failure. METHODS: Type III acromial fractures were simulated on 19 Sawbones scapulae and plated with either a lateral clavicular plate (LatCP), a locking compression plate (LCP), or a reconstruction plate (RecoP)...

BACKGROUND: Although various surgical techniques have been used to treat irreparable rotator cuff tears (RCTs), debate remains regarding which treatment is most effective. The purpose of our study was to compare the outcomes of partial rotator cuff repair versus repair with augmentation of the tenotomized long head of the biceps tendon (LHBT). METHODS: This study included 76 patients with large to massive RCTs. Arthroscopic rotator cuff repair with LHBT augmentation was performed in 39 patients (group I), while partial repair was performed in 37 patients (group II)...

BACKGROUND: This prospective study compared the outcomes after 3 different treatments for large and massive rotator cuff tears. METHODS: Patients with a diagnosis of large-to-massive rotator cuff tears were prospectively included. Patients were allocated in 3 groups: (1) arthroscopic complete repair (repair group), (2) open repair and xenograft patch augmentation (patch group), and (3) arthroscopic débridement and tenotomy of the long head of the biceps (débridement group)...

BACKGROUND: This study proposes a method for inferring the premorbid glenoid shape and orientation of scapulae affected by glenohumeral osteoarthritis (OA) to inform restorative surgery. METHODS: A statistical shape model (SSM) built from 64 healthy scapulae was used to reconstruct the premorbid glenoid shape based on anatomic features that are considered unaffected by OA. First, the method was validated on healthy scapulae by quantifying the accuracy of the predicted shape in terms of surface distance, glenoid version, and inclination...

BACKGROUND: Rotator cuff tears following anatomic total shoulder arthroplasty increase with duration of follow-up. This study aimed to evaluate contact pressure between the rotator cuff tendons and prosthesis after anatomic total shoulder arthroplasty and compare these with the tendon-contact pressures in the native shoulder. METHODS: Eight entire upper extremities were mounted onto a testing apparatus, and simulated muscle loading was applied to each rotator cuff tendon with the shoulder positioned in abduction, internal rotation, and external rotation...

BACKGROUND: Treatment of rotator cuff (RC) tears has not included bipolar muscle-tendon transfers to date. The objective of this study was to verify the feasibility of pedicled bipolar teres major (TM) transfer over and under the long head of the triceps brachii (LHT) and compare its versatility with monopolar transfer in a model of supraspinatus (SS) tears in cadavers. METHODS: In 6 shoulders of cryopreserved cadavers, we re-created complete SS tears, conducting monopolar and bipolar TM transfers over and under LHT...

BACKGROUND: The location of capitellar osteochondritis dissecans (OCD) lesions in the sagittal plane guides the surgical approach used for autologous osteochondral transplantation. We sought to compare the capitellar region accessible for orthogonal graft placement through 3 approaches: (1) posterior anconeus-split approach; (2) lateral approach with lateral collateral ligament (LCL) preservation (LCL-preserving lateral approach); and (3) lateral approach with LCL release (LCL-sacrificing lateral approach)...

BACKGROUND: Although the pronator teres muscle, a major dynamic stabilizer of elbow valgus stress during throwing, frequently presents stiffness, its relationship with elbow injuries in youth baseball players is unknown. This study investigated the relationship between the elasticity of the pronator teres muscle and elbow injuries in youth baseball players. METHODS: The strain ratio (SR) of 15 individuals with osteochondritis dissecans of the humeral capitellum (OCD group), 67 individuals with medial epicondylar fragmentation (medial injury group), and 115 healthy individuals (control group) was measured as the index of the elasticity of the pronator teres muscle using ultrasound strain elastography...

BACKGROUND: Advances in DNA sequencing technologies have made it possible to detect microbial genome sequences (microbiomes) within tissues once thought to be sterile. We used this approach to gain insights into the likely sources of Cutibacterium acnes (formerly Propionibacterium acnes) infections within the shoulder. METHODS: Tissue samples were collected from the skin, subcutaneous fat, anterior supraspinatus tendon, middle glenohumeral ligament, and humeral head cartilage of 23 patients (14 male and 9 female patients) during primary arthroplasty surgery...

BACKGROUND: A variety of techniques currently exist for ulnar collateral ligament (UCL) reconstruction in symptomatic overhead athletes, all with the potential complication of fracture about the humeral or ulnar tunnels. Far cortical button fixation is a reproducible, biomechanically attractive option; however, no clinical series has been published on this technique to date. This study reports the clinical outcomes, with minimum 2-year follow-up, of a dual far cortical button suspension technique for UCL reconstruction in athletes...

BACKGROUND: This cadaveric study was designed to analyze the safety of endoscopic repair of distal biceps tendon (DBT) tears using 2 reattachment techniques. We evaluated the proximity of neurovascular structures to endoscopy portals; iatrogenic injury to neurovascular, musculotendinous, and osseous structures; and changes in compartment pressures. We hypothesized that an all-endoscopic repair of the ruptured DBT would be technically safe and the risk of iatrogenic injury would be low...

BACKGROUND: The opioid epidemic remains a serious issue in the United States with significant impact to the medical and socioeconomic welfare of communities. We sought to determine baseline opioid use in patients undergoing shoulder arthroplasty (SA) and identify patient characteristics, comorbidities, and surgical risk factors associated with postoperative opioid use. METHODS: A Shoulder Arthroplasty Registry identified the number of dispensed opioid medication prescriptions (Rxs) in the first postoperative year in patients who underwent elective primary SA from 2008 to 2014...
