»: In the past 20 years, there has been a substantial increase in the prevalence of pectoralis major injuries, largely related to the rising popularity of weight-lifting and participation in contact sports.
»: Treatment options are influenced by the severity of the injury, patient age, and the amount and type of physical activity.
»: Although there is no consensus as to which treatment method is most effective, previous studies have demonstrated increased satisfaction among patients who undergo operative treatment.
»: The average length of time from surgery to return to activity ranges from 6 to 24 months.

Osteopetrosis is a rare systemic skeletal disorder characterized by increased bone density and mass resulting from suboptimal or impaired resorption of osteoclastic bone. Compromised bone marrow function and associated disorders of red blood cells contribute to hematopoietic abnormalities, which exacerbate the risk of complex, recurrent infections such as jaw osteomyelitis. This case report describes the treatment of a 68-year-old Korean female with autosomal-dominant osteopetrosis who presented with severe and persistent jaw osteomyelitis complicated by hematopoietic dysregulation.

Purpose: Although previous studies have compared strength-training adaptations between free weights (FW) and machine-guided exercises, those studies did not use a Smith machine (SM), which most closely replicates the exercises performed with FW. Thus, the aim of the present study was to investigate the chronic effects of strength-focused, velocity-based training regimens using FW versus SM.
Methods: Thirty-seven sport-science students (14 female) were assigned, balanced by sex and relative strength, to either an FW or SM training group.

Background: The pectoralis major myocutaneous pedicled (PMMP) flap is still considered by many a workhorse flap in head and neck (H&N) reconstruction, despite free flap surgery advancing. The authors aimed to examine this claim and associated myths and controversies by analyzing literature trends and revealing the role of the PMMP flap in a well-established microsurgery center.
Methods: The senior author's reconstructive H&N practice between 1995 and 2022 was reviewed to describe and critically judge primary and secondary PMMP flap decisions to provide invaluable lessons learned and debunk common controversies related to complex H&N reconstruction.

EMG feedback improves force control of a myoelectric hand prosthesis by conveying the magnitude of the myoelectric signal back to the users via tactile stimulation. The present study aimed to test if this method can be used by a participant with a high-level amputation, and whose muscle used for prosthesis control (pectoralis major) was not intuitively related to hand function. Vibrotactile feedback was delivered to the participant's torso, while the control was tested using EMG from three different muscles.

Rupture of the pectoralis major muscle is extremely rare in adolescents. The current literature contains only 5 reports of this condition in patients under 20 years old, with 2 reports in subjects under 16. In the present article, we report the case of a 15-year-old volleyball player who suffered a traumatic rupture of the pectoralis major in a match during the serve movement.
