Background There are few biomechanical studies regarding partial-thickness rotator cuff tears and subsequent repair. Hypothesis Partial-thickness intra-articular supraspinatus tendon increase articular-sided strain as they in size. Repair of these will return to the intact state. Study Design Controlled laboratory study. Methods Twenty fresh-frozen human cadaveric shoulders were prepared by dissecting leaving native footprint intact. The was measured with digital calipers divided into thirds...

Due to the recent rapid expansion of scooter sharing companies, there has been a dramatic increase in number electric (e-scooter) injuries. Our purpose was conduct systematic review characterize demographic characteristics, most common injuries, and management patients injured from scooters.We searched PubMed, EMBASE, Scopus, Web Science databases using variations term "electric scooter". We excluded studies conducted prior 2015, with population less than 50, case reports, not focused on...

The goal of this study was to evaluate the outcomes patients selecting nonoperative treatment for distal biceps tendon ruptures provide information and caregivers consider in decision making. Five men conservatively treated rupture between November 2002 December 2006 were compared 5 age-matched controls operatively. Outcomes at 4.5 years included supination strength, range motion, American Shoulder Elbow Surgeons (ASES) score. Two groups 9 normal volunteers—1 young group averaging 30.7 1...

Background: Hallux metatarsophalangeal (MP) joint arthrodesis for hallux varus is generally reserved severe deformity, failed surgery or the development of osteoarthritis. The purpose this study was to determine radiologic results MP following treatment varus. Our hypothesis that in process correcting valgus angle, 1-2 intermetatarsal angle (1-2 IMA) and (HVA) will be improved due correction deforming forces. Methods: A retrospective review performed on 26 patients with 29 feet had...

Background: Non-insertional Achilles tendinopathy is a common disorder that may be treated with surgical debridement. A flexor hallucis longus (FHL) transfer recommended if debridement of ≥50% performed; however, there are no biomechanical data to support this. The purpose this study was assess the added strength provided by an FHL incrementally sized non-insertional tendon defects. Methods: Thirty matched-pair below-the-knee cadaveric specimens (n = 60) (mean age at time donor death, 67...

Patient-reported outcome measures serve as an invaluable tool in both the clinical and research setting to monitor a patient's condition efficacy of treatments over time. We aim validate Single Assessment Numeric Evaluation (SANE) score for disorders lower extremity using revised-Foot Function Index (rFFI) reference. The SANE is 1-question survey that may improve efficiency data collection setting.Patient age, sex, visit diagnosis by ICD-10 code, score, rFFI were collected retrospectively...

Background: There is increasing emphasis on assessing resident competency, but little has been published how to best evaluate trainee competency for ankle arthroscopy. The purpose of this study was validate an objective model basic arthroscopy knowledge and operative skills a cadaveric ankle. Methods: Diagnostic Ankle Arthroscopy Skills Scoring System adapted from previously validated assessment tools knee scoring system included (1) oral questionnaire (0-23 points), (2) task-specific...

Proximal opening wedge osteotomy (POWO) is an established procedure for moderate to severe hallux valgus. A common concern of this that it results in lengthening the first metatarsal, which could cause increased intra-articular pressure metatarsophalangeal joint (MTP) and may ultimately lead arthritis because these altered mechanics. The purpose study was use a cadaveric model compare pressures articulating contact properties MTP following either scarf or POWO.Fresh-frozen below-knee...

Background: The diagnosis of medial ankle instability in Weber B fractures remains controversial. Manual stress and gravity radiographs as well magnetic resonance imaging (MRI) are used, but there is no consensus gold standard. purpose this study was to determine the relationship between initial fibular displacement clear space widening on a radiograph predictor instability. Methods: A retrospective review conducted all patients with isolated both injury view from August 1, 2014, through...

Traditional treatment for stage II posterior tibial tendon (PTT) dysfunction includes flexor digitorum longus (FDL) transfer combined with various osteotomies. However, the FDL has been shown to be much weaker than PTT and thus may not ideal transfer. Furthermore, peroneus brevis continues a deforming force following reconstructive surgery contribute recurrent deformity. This paper presents novel technique consisting of reconstruction allograft osteotomies necessary correction. Level...

Background: Insertional Achilles tendinopathy (IAT) is a common source of heel pain in active adults and athletes. The Zadek osteotomy (ZO) calcaneal dorsal closing wedge that has demonstrated clinical success as treatment for IAT, purported to favorably improve tendon mechanics, decrease impingement, pressure within the retrocalcaneal bursa. present study aims evaluate biomechanical effects ZO on strain, position Haglund prominence relative insertion, pressure. Methods: was performed 10...

Category: Hindfoot; Sports Introduction/Purpose: Insertional Achilles tendinopathy is a common source of heel pain in active adults and athletes. This may occur conjunction with Haglund’s deformity, calcaneal prominence that can be associated inflammation the retrocalcaneal bursa. Corrective surgery indicated after failed nonoperative treatment. One option includes Zadek osteotomy, dorsal closing wedge which relieve pressure, resulting improved clinical outcomes. However, gap knowledge base...

Category: Hindfoot; Ankle Introduction/Purpose: Given high patient expectations in the setting of complex surgeries, orthopedic surgeons are at risk being subject to malpractice claims. Consequently, medical lawsuits can impose significant economic and psychological burden on surgeons. This study aims investigate claims against podiatrists performing hindfoot arthrodesis determine factors associated with plaintiff verdicts settlements using Westlaw legal database. Methods: The database was...

Treatment options for distal biceps tendon ruptures are vast, including conservative treatment and many techniques surgical repair. Surgical repair of is indicated in patients wanting to restore supination strength endurance. In most cases, direct anatomic indicated, with the two-incision technique modified by Morrey considered standard. Superior outcomes compared have been well established. Most contemporary focus on single-incision approach types fixation suture anchors, cortical buttons...

Category: Other Introduction/Purpose: Patient reported outcome measures serve as an invaluable tool in both the clinical and research setting to monitor a patient’s condition efficacy of treatments over time. We aim validate Single Assessment Numeric Evaluation (SANE) score for disorders lower extremity using revised Foot Function Index (rFFI) reference. The rFFI is validated 34-question survey utilized evaluation patients with foot ankle related pathology [1-4], while SANE consists single...
