Lidocaine patches after cesarean sections: a randomized control trial.

Objectives: Lidocaine patches are a common topical analgesic therapy but have not been thoroughly investigated in the surgical or obstetric literature. We sought to investigate the impact of adding topical lidocaine patches to routine postcesarean pain management on patients' postcesarean pain scores and opioid use.

Study Design: This is a prospective randomized subject-blinded controlled trial of patients undergoing cesarean delivery at a single institution.

A randomised crossover trial on the effects of foot starting position on calf raise test outcomes: Position does matter.

Background: This randomised crossover study with repeated measures examined the influence of the three most common foot starting positions used in conducting the calf raise test (CRT) on test outcomes. This study also accounted for the potential influence of gender, age, body mass index (BMI), and level of physical activity on test outcomes.

Methods: Forty-nine healthy individuals (59 % female, 21 ± 4 years) performed single-leg calf raise repetitions in a human movement laboratory in three randomised foot starting positions: flat, 10° incline, and step.

Self-regulation, motivation, and outcomes in HyFlex classrooms.

At a public, 4-year, open access university, students were given the choice of how they would attend class: face-to-face, online, or livestream (synchronous session in Microsoft Teams®). The 876 students in this study registered in course sections designated as face-to-face delivery yet were provided attendance flexibility due to the pandemic. This unique situation provided a research opportunity to explore the self-regulatory, motivational, and contextual factors that affected students' attendance choices as well as their academic outcomes (pass/withdrawal) and perceptions of satisfaction.

Concurrent validity and reliability of a mobile iOS application used to assess calf raise test kinematics.

Background: Calf raise test (CRT) is used in rehabilitation and sports medicine to evaluate calf muscle function. The Calf Raise application (CR) uses computer-vision algorithms to objectively measure CRT outcomes and replicate laboratory-based metrics that are difficult to measure clinically.

Objective: To validate the CR by examining its concurrent validity and agreement levels against laboratory-based equipment, and its intra- and inter-rater reliability.

Wound Complications with Multiple Wrist Incisions in Distal Radius Reconstruction.

 Placement and spacing of skin incisions are important for maintaining soft tissue perfusion and viability, particularly in the setting of local trauma.  The aim of this article is to determine if multiple skin incisions in the surgical management of distal radius fractures result in an increased risk of postoperative wound complications, particularly in the setting of high-energy mechanisms of injury with substantial initial displacement and associated soft-tissue insult that require multiple incisions for distal radius reconstruction.  A multicenter, retrospective chart review was performed for all adult patients who underwent open reduction, internal fixation of a closed distal radius fracture with multiple (≥2) hand, and wrist incisions with minimum follow-up of 6 weeks.

Ancient DNA reveals five streams of migration into Micronesia and matrilocality in early Pacific seafarers.

Micronesia began to be peopled earlier than other parts of Remote Oceania, but the origins of its inhabitants remain unclear. We generated genome-wide data from 164 ancient and 112 modern individuals. Analysis reveals five migratory streams into Micronesia.

Single Incision, Dual Window Approach for a Comminuted Distal Radius Fracture.

 Complex distal radius fractures often involve a fragment of the volar-ulnar articular surface and the radial styloid. The volar ulnar corner of the distal radius is an important constraint to volar translation of the carpus and thus requires stable fixation to prevent wrist displacement. The traditional volar Henry approach often requires undue tension on the median nerve while retracting for access to the ulnar aspect of the radius.

Study Design: This single-center parallel-group randomized controlled external pilot study (ClinicalTrials.

Biomechanical comparison of tenorrhaphy constructs for tendon reconstructions and transfers.

With tendon transfers or reconstructions, the tenorrhaphy must be strong enough to withstand early mobilization in the immediate postoperative period to decrease adhesion formation and optimize functional outcomes. The purpose of this study was to compare the strength, bulk, and gliding resistance of four common tendon-to-tendon attachment constructs. A biomechanical study was performed utilizing 80 cadaveric tendons to compare four common tendon tenorrhaphy constructs: the end-weave (EW); Pulvertaft (PT); single-pass, side-to-side (SP-STS); and simple, side-to-side (STS) attachments.

The Influence of Asymptomatic Hypermobility on Unanticipated Cutting Biomechanics.

Background: Generalized joint hypermobility is an important risk factor for knee injuries, including to the anterior cruciate ligament (ACL). Examining movement patterns specific to hypermobile individuals during sport-specific movements could facilitate development of targeted recommendations and injury prevention programs for this population.

Hypothesis: Asymptomatic hypermobile participants will present kinematics measures suggestive of a greater risk of noncontact knee or ACL injuries.

Which jump-landing task best represents lower extremity and trunk kinematics of unanticipated cutting maneuver?

Background: The double-leg jump-landing (DLJL) task is commonly used as a movement screen that can be implemented in large cohorts of athletes. However, it is debatable whether the DLJL is ecologically valid and reflects sporting requirements or injury-prone situations, such as cutting and pivoting.

Research Question: Which jump-landing movement variation best represents the kinematics of unanticipated side-step cutting?

Methods: Forty-two participants (25 males and 17 females) performed unanticipated side-step cutting and four jump-landing tasks: DLJL, rotated DLJL (DLJL), single-leg jump-landing (SLJL), and rotated SLJL (SLJL).

Treatment for Acute Proximal Interphalangeal Joint Fractures and Fracture-Dislocations: A Systematic Review of the Literature.

Proximal interphalangeal joint (PIPJ) fractures and fracture-dislocations are common hand injuries and recognition of this injury pattern is essential in the management of these fractures. Although a variety of treatment options have been reported in the literature, the optimal treatment remains controversial. MEDLINE, EMBASE, and The Cochrane Library Database were screened for treatment strategies of PIPJ fracture and fracture-dislocation.

Biomechanical Comparison of Tendon Coaptation Methods With a Meshed Suture Construct.

Purpose: Tendon-to-tendon attachment constructs for tendon reconstructions or transfers need to be secure in order to allow early mobilization after surgery. The purpose of this study was to biomechanically compare 2 common constructs secured with a novel mesh suture versus a nonabsorbable braided suture.

Methods: We used 100 cadaveric tendons to create 5 different tendon coaptation constructs (a to e) (10 coaptations per group): (a) Pulvertaft weave with a braided suture (PTe); (b) mesh suture (PTm); (c) single-pass, side-to-side (SP-STS) coaptation with 30-mm overlap using a mesh suture (SP-STS-30m); (d) SP-STS 50-mm overlap with a mesh suture (SP-STS-50m); and (e) SP-STS with 30-mm tendon overlap using a braided suture (SP-STS-30e).

Effect of Trapeziectomy on Carpal Stability.

The scaphoid-trapezoid-trapezium (STT) articulation stabilizes the scaphoid and links the proximal and distal carpal rows. The purpose of the study was to determine whether trapezium excision in the treatment of trapeziometacarpal (TM) arthritis affects carpal stability. A retrospective chart and radiographic review was performed on all wrists that underwent trapeziectomy with suspensionplasty or ligament reconstruction, and tendon interposition for TM arthritis between 2004 and 2016.

Using 311 data to develop an algorithm to identify urban blight for public health improvement.

The growth of administrative data made available publicly, often in near-real time, offers new opportunities for monitoring conditions that impact community health. Urban blight-manifestations of adverse social processes in the urban environment, including physical disorder, decay, and loss of anchor institutions-comprises many conditions considered to negatively affect the health of communities. However, measurement strategies for urban blight have been complicated by lack of uniform data, often requiring expensive street audits or the use of proxy measures that cannot represent the multifaceted nature of blight.
