The role and function of the acetabular labrum have been studied extensively in the past decade. Recent studies have proposed that, in addition to causing pain and mechanical symptoms, labral tears may accelerate arthritis. Labral preservation is believed to be important because of the role the labrum plays in maintaining a healthy joint. Treatment of the acetabular labrum is becoming one of the fastest growing fields in orthopaedics; therefore, the treatment decision-making process must be refined. Currently, three commonly practiced labral treatments are available: repair, débridement, and reconstruction...

The goal of this study is to clarify the development of the long head of the biceps brachii tendon (LHBT) and to verify the existence and development of the coracoglenoid ligament. Histological preparations of 22 human embryos (7-8 weeks of development) and 43 human fetuses (9-12 weeks of development) were studied bilaterally using a conventional optical microscope. The articular interzone gives rise to the LHBT, glenoid labrum, and articular capsule. During the fetal period, it was observed that in 50 cases (58%), the LHBT originated from both the glenoid labrum and the scapula, while in 36 cases (42%), it originated only from the glenoid labrum...

BACKGROUND: In the past 16 years, the number of prescription opioids sold in the United States, as well as deaths from prescription opioids, has nearly quadrupled. However, the overall amount of pain reported by patients has not changed significantly. Specific information about opioid prescriptions in the perioperative period is lacking. Of the studies that have been published, investigators have shown that the majority of patients have unused postoperative opioid pills. Moreover, patients appear to lack information about disposal of unused opioid pills...

The iliopsoas tendon is an important dynamic stabilizer of the hip joint, and it should be carefully identified and preserved during routine hip arthroscopy. However, it may also be a source of hip pain manifesting as iliopsoas tendinitis or a snapping hip or contributing to the development of labral pathology caused by psoas impingement. In the appropriately indicated, refractory cases of iliopsoas-related hip pain, surgical intervention in the form of an iliopsoas tenotomy at the level of the labrum can result in reliable pain relief...

Minimally invasive percutaneous radiofrequency ablation (RFA) techniques are the standard of care for treating simple osteoid osteomas (OOs). Historically, OOs were treated with open en bloc resection or curettage of the nidus. RFA procedures have been linked to soft-tissue complications of varying severity. In addition, RFA may be a poor choice for periarticular OOs because of the potential for procedure-related articular cartilage damage. Hip arthroscopy is a widely accepted approach for the treatment of femoroacetabular impingement...

Femoroacetabular impingement (FAI) is an increasingly recognized cause of hip pain. This pathology often involves abnormal femoral neck shape (cam-type FAI), acetabular over coverage (pincer-type FAI), or mixed pathology. Surgical treatment of this entity includes labral repair and femoral head-neck osteochondroplasty. A mindful arthroscopic technique is of paramount importance, because maintaining the integrity of the labrum and a corresponding neck volume has been reported to be vital in maintaining the hip suction seal...

Recurrent anterior shoulder instability with significant bone loss represents a surgical challenge. Anterior bone block procedures including variations of the Latarjet coracoid transfer have been used in this setting. Bone graft resorption with prominence of the metalwork is a serious concern, whereas the relative contribution of the dynamic sling effect of a Latarjet procedure is still controversial. We describe an arthroscopic technique for anatomic reconstruction of anterior glenoid bone defects using autologous iliac crest graft...

INTRODUCTION: Repairs of labral tears are performed for unstable tears, hip instability, and after detachment concomitant to the treatment of femoroacetabular impingement (FAI), but limited data is known about the strength of repair. This study evaluated the effect of simulated axial weight-bearing on suture anchor based repair of the acetabular labrum. METHODS: 3 cadaveric pelvises underwent creation of a 1.5 cm anterior-superior labral tear in each hip. The tears were then repaired using 2 suture anchors per hip...

BACKGROUND: Physical examination tests of the shoulder (PETS) are clinical examination maneuvers designed to aid the assessment of shoulder complaints. Despite more than 180 PETS described in the literature, evidence of their validity and usefulness in diagnosing the shoulder is questioned. METHODS: This meta-analysis aims to use diagnostic odds ratio (DOR) to evaluate how much PETS shift overall probability and to rank the test performance of single PETS in order to aid the clinician's choice of which tests to use...

BACKGROUND: Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results' using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. METHODS: This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications...
