Single Medial-Row Anchor With Biceps Tenodesis in a Transosseous Double-Row Construct for Massive Rotator Cuff Tear.

Massive rotator cuff tears are a common issue for patients and can be challenging to manage surgically. While the literature has shown that repair construct can affect the outcome of a rotator cuff repair, and the double-row repair is typically favored over the single-row repair for larger rotator cuff tears, the double-row repair also has some shortcomings. These shortcomings are related to the increased technical difficulty of the procedure, as well as increased costs due to the increased number of anchors used. Both of these factors also lead to an increase in the amount of time spent in the operating room as well. This study describes a surgical technique to help mitigate this shortcoming of the double-row repair by using a single medial-row anchor in our double-row construct for repair of a massive rotator cuff tear.

The devastating effects of humeral nonunion on health-related quality of life.

BACKGROUND: Humeral nonunion is estimated to occur at a rate of 1.1%-25% depending on the fracture location and pattern, mechanism of injury, patient compliance with the immobilization protocol and patient's nutritional status and medical comorbidities. Fracture nonunion can cause chronic pain and limited range of motion and may hinder normal function. There is very little data from the patients' perspective regarding their experience with a humeral nonunion. The aim of this study was to establish health-related quality of life (HRQoL) norms for patients diagnosed with a humeral nonunion. MATERIALS AND METHODS: We reviewed a prospectively collected database of 185 humeral nonunions seen and treated at our quaternary referral center. We recorded patient characteristics including sex, age, history of infection, previous surgery, associated nerve palsy, handedness, and the anatomic location of the nonunion. At initial clinical evaluation, all patients were asked to complete the 12-Item Short Form Health Survey (SF-12), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, Brief Pain Inventory (BPI), and a time trade-off questionnaire. These scores were compared to other well-known chronic medical conditions' HRQoL scores. RESULTS: The cohort reported an average utility score of 0.55 ± 0.35, average SF-12 Physical Component Summary score of 30.2 ± 7.6, average SF-12 Mental Component Summary score of 42.5 ± 6.1, and average raw DASH score of 69 ± 21, which was worse than the general US population, patients with asthma, hypertension, stroke, type 2 diabetes, and AIDS. Patients with humeral nonunion are willing to trade 45% of their remaining life to obtain perfect health, and when stratified by handedness, we found that patients with a humeral nonunion of their dominant arm were willing to trade 49.7% compared with 39.7% in patients with a humeral nonunion of their nondominant arm (P = .04). DISCUSSION: The results of our study show that humeral nonunion is a chronic medical condition that has a debilitating effect on patients, both physically and mentally. It is important for orthopedic surgeons to acknowledge these conditions as physically and mentally debilitating to their patients. Our study highlights these physical and mental burdens and helps to quantify humeral nonunion in relation to more well-known chronic conditions, such as asthma, diabetes, AIDS, and stroke. CONCLUSIONS: Humeral nonunions have a devastating effect on a patient's physical and mental health with HRQoL measures lower than patients with other chronic conditions, such as asthma, diabetes, AIDS, and stroke. We found that our patients, on average, would trade approximately 45% of their remaining life span for perfect health.

The glenoid-intramedullary humeral angle: a measurement of compensatory scapular abduction in advanced rotator cuff arthropathy and its potential effects on implant choice.

BACKGROUND: This study establishes measurements to evaluate pathologic compensation in rotator cuff tear arthropathy and resultant considerations for reverse shoulder arthroplasty. METHODS: Radiographs of patients with intact rotator cuffs were measured establishing interobserver and intraobserver reliability. Reverse shoulder arthroplasty cases performed by a single surgeon were then retrospectively reviewed. One year of follow-up radiographs were required for inclusion. Preoperative radiographs were analyzed for relative humeral head elevation ratio and humeral abduction relative to the glenoid face, termed the glenoid-intramedullary humeral angle. Statistical analyses assessed associations for radiographic measurements with presence and severity of scapular notching based on the Nerot-Sirveaux classification system. RESULTS: A total of 221 patients met inclusion criteria. At the 1-year follow-up, 61 (27.6%) shoulders had radiographic notching. There was a moderately strong (r = -0.56) negative correlation between glenoid-intramedullary humeral angle and humeral head elevation ratio. Patients with humeral head elevation ratio ≥ 20% were significantly (P = .024) and 9.2 times more likely to have notching of any grade. Patients with glenoid-intramedullary humeral angle ≤ 5 degrees were significant (P < .0001) and 6.7 times more likely to have notching of any grade and significantly (P = .00018) and 145 times more likely to have high-grade (3 and 4) notching. CONCLUSIONS: Preoperative humeral head elevation and compensatory scapular rotation with relative adduction of the humerus have significant associations with high-grade notching. These radiographic findings have potential to help surgeons in preoperative decision-making regarding implant choice and patient education.

Anterior Vertebral Body Tethering for Adolescent Scoliosis with Growth Remaining: A Retrospective Review of 2 to 5-Year Postoperative Results.

BACKGROUND: Anterior vertebral body tethering (VBT) is an early treatment option for progressive scoliosis in pediatric patients, allowing for continued deformity correction during normal growth. We report postoperative radiographic and clinical outcomes for patients treated with VBT. METHODS: This clinical and radiographic retrospective review of 31 consecutive patients included an analysis of preoperative, perioperative, and postoperative details, including the Lenke classification; Cobb angle measurements of the proximal thoracic, main thoracic, and lumbar curves; the sagittal profile; and skeletal maturity. Successful outcomes were defined by a residual curve of ≤30° in skeletally mature patients who did not undergo a posterior spinal fusion (PSF). RESULTS: Of the 31 patients treated, 29 met the inclusion criteria, and 2 were lost to follow-up. The mean patient age (and standard deviation) at the time of the surgical procedure was 12.7 ± 1.5 years (range, 10.2 to 16.7 years), with most patients classified as Risser grade 0 or 1 (52%) and Sanders stage 3 (32%). A mean of 7.2 ± 1.4 vertebral levels were instrumented, with a minimum preoperative Cobb angle of 42°. At the latest follow-up, 27 patients had reached skeletal maturity (Sanders stage ≥7) and 20 patients exhibited a curve magnitude ≤30°, for a success rate of 74%. A suspected broken tether occurred at ≥1 level in 14 patients (48%). Two patients underwent PSF and 4 had tether revision. The overall revision rate was 21% (6 of 29). CONCLUSIONS: This study shows the success and revision rates as well as the impact of a suspected broken tether on the procedural success of VBT. Despite our patient population being slightly more mature at the time of the surgical procedure compared with previous studies, we had a higher success rate and a lower revision rate. A PSF was avoided in 93% of patients, indicating that VBT may be a reliable treatment option for adolescent scoliosis in skeletally immature individuals. LEVEL OF EVIDENCE: Therapeutic Level IV.

Eccentric Reaming for B2 Glenoids: History, Preoperative Planning, Surgical Technique, and Outcome.

BACKGROUND: The biconcave (B2) glenoid is characterized by preservation of the anterior portion of the native glenoid with asymmetric wear of the posterior glenoid. Surgical options for glenoid correction have evolved. The goal of shoulder arthroplasty is to place the implants in such a manner to return the humeral head to a centered position and restore the joint line to a neutral position. There is no current consensus on method of treatment and correction. METHODS: The current and historical literature on total shoulder arthroplasty was used to examine technique viability. RESULTS: Asymmetric remaining can be used to address up to 15° of version correction without compromise of cortical bone. It is important to have the proper presurgical planning, to understand the limitations of correction, and to have other options available to treat the biconcave glenoid.

The Impact of Child Safety Restraint Status and Age in Motor Vehicle Collisions in Predicting Type and Severity of Bone Fractures and Traumatic Injuries.

BACKGROUND: Although morbidity and mortality in children increases in motor vehicle collisions (MVC) if child restraints are not used, no data exist correlating specific injuries with proper or improper use of safety restraints or age. The purpose of this study was to evaluate correlations between childhood MVC injuries, age, and restraint status. METHODS: A medical record search for pediatric patients involved in a MVC was conducted at a pediatric hospital (level 1 trauma). Charts were reviewed for demographics and injury-specific information. Patients were grouped by age, restraint use, and injuries. RESULTS: Nine hundred sixty-seven patients ≤12 years (average age 6.39 y) were identified. Being properly restrained was most common in all age groups except the 4- to 8-year age group in which being improperly restrained was most common. Unrestrained patients were most commonly found in the 9- to 12-year age group. A statistically significant difference was not observed for orthopaedic injuries among the restraint groups, but internal thoracic injuries, open head wound, and open upper extremity wounds were significantly more common in improperly or unrestrained patients. Improperly restrained infants had a significantly higher rate of intracranial bleeds and abrasions than those properly restrained. Unrestrained and improperly restrained 9- to 12-year olds had significantly more open head, open upper extremity, and vascular injuries. When comparing injury types with age groups, upper extremity fractures, femoral fractures, dislocations, and spinal fractures were found to be significantly higher in older children. CONCLUSIONS: Preventing orthopaedic injuries in older children may be accomplished by changes in regulations or automotive safety equipment. Rear-facing child safety seats could possibly be improved to prevent head trauma in the youngest patients. There is a continued need to reinforce the importance of proper use of child safety devices to parents. Knowledge of the patient's age, along with restraint status, might aid in diagnosis of less obvious MCV injuries. LEVEL OF EVIDENCE: Level III.

Accessibility and Availability of Online Information for Orthopedic Surgery Residency Programs.

BACKGROUND: Prospective orthopedic residency applicants commonly use one of three databases to identify potential programs: Accreditation Council of Graduate Medical Education (ACGME), American Medical Association (FREIDA), or Orthogate. org. In addition, institutional websites are typically the primary source of information once programs are identified. We sought to evaluate the databases and websites used by prospective orthopedic surgery applicants for content and accessibility. We hypothesized that information would be more available in comparison to previous studies but would still fail to provide complete, up to date program information for the prospective applicant. METHODS: Three online databases were queried in December 2014 to compile a list of orthopedic residency programs in the United States. This combined list was used as a basis for evaluating individual institution websites. Previously described criteria were used to evaluate the availability of information contained within orthopedic surgery residency websites. RESULTS: At the time of online review, 157 programs were identified. Depending on the database in question, up to 33% of programs either did not provide a link or listed a non-functioning link. Among the variety of evaluated criteria, inclusion of the information varied between 12% and 97% for the individual program websites. CONCLUSIONS: Online databases are useful in listing programs, but individual program details and direct functional links are lacking. Most program websites contain varying degrees of desired information; however, not all programs maintain websites which consistently provide information to satisfy the evaluated criteria in this study. Improved online accessibility and availability of information for residency programs would increase their visibility and utility for prospective applicants.

Bradford's law: identification of the core journals for neurosurgery and its subspecialties.

OBJECTIVE: Bradford's law describes the scatter of citations for a given subject or field. It can be used to identify the most highly cited journals for a field or subject. The objective of this study was to use currently accepted formulations of Bradford's law to identify core journals of neurosurgery and neurosurgical subspecialties. METHODS: All original research publications from 2009 to 2013 were analyzed for the top 25 North American academic neurosurgeons from each subspecialty. The top 25 were chosen from a ranked career h-index list identified from previous studies. Egghe's formulation and the verbal formulation of Bradford's law were applied to create specific citation density zones and identify the core journals for each subspecialty. The databases were then combined to identify the core journals for all of academic neurosurgery. RESULTS: Using Bradford's verbal law with 4 zone models, the authors were able to identify the core journals of neurosurgery and its subspecialties. The journals found in the most highly cited first zone are presented here as the core journals. For neurosurgery as a whole, the core included the following journals: Journal of Neurosurgery, Neurosurgery, Spine, Stroke, Neurology, American Journal of Neuroradiology, International Journal of Radiation Oncology Biology Physics, and New England Journal of Medicine. The core journals for each subspecialty are presented in the manuscript. CONCLUSIONS: Bradford's law can be used to identify the core journals of neurosurgery and its subspecialties. The core journals vary for each neurosurgical subspecialty, but Journal of Neurosurgery and Neurosurgery are among the core journals for each neurosurgical subspecialty.
