Charles Nathan Vannatta, Thomas W Kernozek, Naghmeh Gheidi
Gait retraining is a common form of treatment for running related injuries. Proximal factors at the hip have been postulated as having a role in the development of running related injuries. How altering footstrike affects hip muscles forces and kinematics has not been described. Thus, we aimed to quantify differences in hip muscle forces and hip kinematics that may occur when healthy runners are instructed to alter their foot strike pattern from their habitual rear-foot strike to a forefoot strike. This may gain insight on the potential etiology and treatment methods of running related lower extremity injury...

INTRODUCTION: The concept of a dual mobility (DM) cup has been in existence for more than 40 years and was initially popularized in Europe. Only recently has it started to garner attention in the United States. Its design, consisting of a small femoral head articulating within a larger polyethylene (PE) insert, which articulates with an outer shell, has found increasing use in patients that are at risk for post-operative dislocations. This case report describes a case of recurrent total hip arthroplasty (THA) dislocation managed with the implantation of a DM cup with an acute intraprosthetic dislocation of the DM construct...

A postural evaluation of commercial licensed truck drivers was conducted to determine the ergonomic benefits of a truck seat prototype in comparison to an Industry standard seat. Twenty commercially licensed truck drivers were recruited to perform a 90-min driving task. Postures were assessed using accelerometers and a backrest and seat pan pressure mapping system. Subjective discomfort measurements were monitored using two questionnaires: ratings of perceived discomfort (RPD) and the automotive seating discomfort questionnaire (ASDQ)...

PURPOSE OF THE STUDY Although total hip arthroplasty (THA) is one of the most successful orthopedic operations, the soft tissue trauma towards the periarticular musculature during surgical approaches remains a critical concern. However, the actual microstructural proof of muscle trauma on the level of the myofiber due to the surgical approach has never been claimed. MATERIAL AND METHODS Patients undergoing THA were prospectively enrolled and either operated by a direct lateral (DL) or a anterolateral minimally invasive approach (ALMI)...

BACKGROUND/AIMS: Extrinsic and intrinsic skin aging is subject to constant remodeling and degradation processes, primarily in components of the extracellular matrix. While collagen fibers thin out during the aging process, the amorphous elastin fibers accumulate. These are essential formative components of the dermis. So far, these processes have been detected in vertical histological sections of invasive biopsies and recently in noninvasive horizontal scans. METHODS: In this pilot study, a modified noninvasive 2-photon microscope was applied to measure the collagen/elastin index of skin in vivo...

Umran Sarwar, Jason Ting
Compartment syndrome, a surgical emergency, is caused by an increase in pressure within a closed osseofascial space, often due to trauma. This causes a decrease in tissue perfusion and ultimately tissue necrosis and multiorgan failure if not treated in a timely fashion. Gluteal compartment syndrome is a rare variant and often caused by a period of immobilisation secondary to intoxication with alcohol or drugs or during long operations, typically in the supine position. We report on a case of gluteal compartment syndrome developing in a patient postoperatively following a long microsurgical procedure to a hand, which has not been documented before...

BACKGROUND: Free and local flaps based on the profunda artery perforators were first used for reconstruction of pressure sores, burn contractures, and extremity wounds. Recently, a revised profunda artery perforator flap was introduced for breast reconstruction. However, despite increasing reports of the use of the flap, it remains a rarely used option. The authors present their early experience with the first 101 profunda artery perforator flaps used for breast reconstruction at their institution...

This study aimed to identify patients' physical and psychosocial experiences of an investigational long-acting injectable PrEP product to aid in the development of patient and provider education materials. Twenty-eight participants of a Phase 2 safety, tolerability, and acceptability study of long-acting integrase inhibitor cabotegravir (CAB-LA) were interviewed on their physical and psychosocial experiences of the injections. Five themes emerged through a framework analysis on these interview transcripts: (1) injection-related pain is highly variable across individuals; (2) pain is more impactful after the injections than during; (3) patient anxiety is critical, but does not determine the experience of injections and decreases over time; (4) intimacy and awkwardness of gluteal injections impacts patients' experiences; (5) patient education and care strategies can mitigate the above factors...

We report a case of sciatica that fulfilled the diagnostic criteria for inferior gluteal vein varicosities according to patient history and on magnetic resonance imaging. Since conservative treatment was ineffective, excision-ligation of the varicose vein was performed as recommended in the previous literature. However, pain was only slightly relieved and then aggravated. Reoperation involving wide release and resection of the piriformis outlet was performed. Pain resolved immediately thereafter. We suggest that this case of sciatica resulted from both piriformis entrapment and vein varicosities...
