Background: Loss of knee extension causes significant impairment. Though nerve-based reconstruction is preferable in cases of femoral nerve palsy or injury, these surgeries are not always appropriate if the pathology involves the quadriceps muscles or presentation too late for muscle reinnervation. Muscle transfers are another option that has been underutilized in the lower extremity. Read More

Liposarcomas constitute rare malignant tumors of the soft tissue, with wide anatomical distribution. The prompt diagnosis of a liposarcoma is extremely challenging since these tumors tend to remain asymptomatic, until they grow enough to displace adjacent anatomical structures. In the presented case, a 55-year-old Caucasian male proceeded to our institution complaining about irreducible swelling of the right iliac fossa and constant discomfort, over the course of a year.

Objective: Prior research has associated assisted injection with risk behaviors, but other risks such as injury, missed veins, and incidental exposures to blood-borne infections during an injection episode have not been assessed. In the following, we present the frequency of these other risks and determine factors associated with missing a vein and incidental blood exposure among people who inject drugs (PWID).

Methods: We conducted a cross-sectional analysis of data from PWID who were recruited using targeted sampling in Los Angeles and San Francisco, California, during 2016 and 2017. Read More

With multipotent differentiation potential and paracrine capacity, mesenchymal stem cells (MSCs) have been widely applied in clinical practice for the treatment of ischemic heart disease. MSCs are a heterogeneous population and the specific population of MSCs may exhibit a selective ability for tissue repair. The aim of our research was to adapt the CD73 subgroup of adipose derived MSCs (AD-MSCs) for the therapy of myocardial infarction (MI). Read More

Background: Acute sternoclavicular fracture-dislocation is associated with high-energy trauma and is being increasingly recognized in children. These injuries are associated with compression of mediastinal structures and can be life-threatening. The management of acute sternoclavicular fracture-dislocation includes closed reduction or open surgical stabilization; however, limited success is reported with closed reduction. Read More

Background: Team-sport players have a particularly high injury risk. Although female sex is considered a risk factor, it is still unknown whether female and male team-sport players, in fact, differ in their injury rates. We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.

A 71-year-old man with residual poliomyelitis was referred to the orthopaedic surgeons with a neglected left femoral neck fracture of the paralytic limb. He had presented at another hospital with left groin pain and inability to weight bear 4 weeks earlier after a fall from standing height, but had delayed treatment due to his insistence on waiting until he returned to his home country.Successful treatment of residual poliomyelitis fractures requires early union as well as early mobilisation and rehabilitation.

Introduction: Chronic postherniorrhaphy inguinal pain (CPIP) is common following inguinal hernia repair. As even primary minimally-invasive inguinal hernia repairs carry a risk of significant intra-operative bleeding, it is unsurprising that reoperative groin exploration and mesh explantation for chronic post-inguinal herniorrhaphy pain confers an even higher risk of arteriotomy or venotomy due to a distorted anatomy and the presence of adhesions. In this report, we present a single institution's experience with the management of intra-operative vascular injury encountered during minimally invasive groin exploration and mesh explantation for CPIP.

Injury prevention strategies in team settings should not overlook early detection and secondary prevention. Monitoring systems may be an effective approach to detect common and troublesome injuries, such as hip and groin pain in football (soccer) players. The purpose of this International Perspective is to share our experiences with monitoring hip and groin pain in youth academy football and discuss challenges that surfaced. Read More

Context: The high rates of adductor injuries and reinjuries in soccer have suggested that the current rehabilitation programs may be insufficient; therefore, there is a need to create prevention and reconditioning programs to prepare athletes for the specific demands of the sport.

Objective: The aim of this study is to validate a rehab and reconditioning program (RRP) for adductor injuries through a panel of experts and determine the effectiveness of this program through its application in professional soccer.

Design: A 20-item RRP was developed, which was validated by a panel of experts anonymously and then applied to 12 injured male professional soccer players. Read More

Psoas muscle hematoma is defined as a spontaneous or traumatic retroperitoneal collection of blood involving the psoas muscle. Early symptoms of an iliopsoas hematoma include lower abdominal or severe groin pain. Although psoas hematoma is a known complication of coagulopathy, psoas hematoma caused by non-penetrating trauma is the subject of only scattered reports and its significance has not been well described in the literature, so the aim of this study was to report a case of blunt traumatic psoas hematoma with the fracture of vertebral transverse process with the presentation of gross hematuria.

Arthroscopy 2021 04;37(4):1179-1181

As one of the many causes of groin pain, iliopsoas tendinitis can be hard to identify and even harder to treat. It occurs in the setting of both the native hip joint and following total hip arthroplasty. Internal snapping, or coxa saltans, can result from the iliopsoas snapping over the anterior hip capsule or iliopectineal eminence and can be a source of labral pathology. Read More

Background: A growing body of literature supports surgical intervention for femoroacetabular impingement (FAI) in young, active athletes. However, factors likely to influence results in this cohort are less clearly defined.

Purpose: To quantify changes in validated patient-reported outcome measures (PROMs) and determine whether differences in baseline athlete demographic characteristics, intraoperative findings, and surgical techniques are associated with achieving improved outcomes and minimal clinically important difference (MCID) after arthroscopic management of sports-related FAI.
