In order to access and resect the acetabular rim, arthroscopic acetabuloplasty was described with labral detachment. When the chondrolabral junction remains intact, acetabuloplasty and labral refixation can be performed maintaining an unharmed labrum. We aimed to evaluate the outcome of a group of patients treated with arthroscopic acetabuloplasty without labral detachment. During the study period, we retrospectively analysed 44 patients with pincer-type o combined impingement and an intact chondroblabral junction, with an average follow-up of 32 months (range: 27-38)...

INTRODUCTION: Acetabular cartilage lesions are frequently found during hip arthroscopy. In the hip joint they mostly occur secondary to a mechanical overload resulting from a pre-existing deformity as hip dysplasia or femoroacetabular impingement (FAI). Lesions identified during arthroscopy can vary greatly from the earliest stages to the most advanced (full-thickness lesions). These lesions occur in the acetabulum in the early stages of joint damage. Microfractures are indicated in full-thickness chondral defects...

Purpose To evaluate the diagnostic accuracies of nonenhanced magnetic resonance (MR) imaging and MR arthrography for diagnosis of superior labrum anterior-to-posterior (SLAP) tears by using a systematic review and meta-analysis. Materials and Methods A comprehensive literature search was performed on the two main concepts of MR imaging (MR imaging, and direct and indirect MR arthrography) and SLAP tears. Inclusion criteria consisted of original studies that assessed the diagnostic accuracy of MR imaging, direct MR arthrography, and/or indirect MR arthrography for the detection of SLAP tears, by using surgical findings as the reference standard...

BACKGROUND: Minor events that occur in the workplace sometimes are evaluated with MRI, which may reveal age-related changes in the symptomatic body part. These age-related changes are often ascribed to the event. However, evidence of similar or worse pathophysiology in the contralateral joint would suggest that the symptoms might be new, but the pathophysiology is not. QUESTIONS/PURPOSES: Using a convenience sample of occupational injury claimants with bilateral MRI to evaluate unilateral knee or shoulder symptoms ascribed to a single event at work, we sought to determine whether MRI findings of the shoulder and knee are more often congruent or incongruent with new unilateral symptoms...

The long head of the biceps tendon (LHBT) is a common source of pathology. The biceps-labral complex (BLC) is the collective anatomic and clinical features shared by the biceps tendon and the superior labrum. LHBT pathology can be caused by inflammation, instability, or trauma. Numerous tests can be performed to determine the existence of biceps tendon and superior labrum anterior to posterior (SLAP) lesions; however, many of these tests do not have high sensitivity and specificity, which limit their clinical utility...

BACKGROUND: Hip pain remains a challenge given the multiple factors that can cause damage to the articular cartilage, such as traumatic injury, metabolic damage, and morphologic variations such as femoroacetabular impingement (FAI) and that can contribute to progression of osteoarthritis. However, a direct relationship between patient characteristics, the extent of acetabular chondral damage, and topologic characteristics of chondral lesions has not been established. PURPOSE: To compare the grade of acetabular chondral damage, measured in terms of acetabular labrum articular disruption (ALAD) classification, to the size and position of the chondral lesions, matching patients' demographic factors such as age and body mass index (BMI)...

The importance of the acetabular labrum has been well documented for the function and overall health of the hip joint. Several biomechanical studies have shown the sealing effect of the acetabular labrum. In the past decade, labral repair procedures have gained increased attention, with the literature suggesting that the outcomes after hip arthroscopy are directly related to labral preservation. However, a primary labral repair can be challenging in cases of hypoplastic, ossified, or complex and irreparable labral tears in which there is insufficient tissue to perform a primary repair...

Walid Reda, Ahmed Khedr
Using a posterolateral portal in passing and tying the inferior knot allows good labral reduction and adequate capsular shift to treat anterior shoulder instability. In this technique, the most inferior anchor is placed through a low anterolateral portal. A penetrating grasper is introduced from a posterolateral portal situated 2 to 3 cm distal and lateral to the viewing portal. This portal is used to pass the 2 limbs of the anchor suture as inferior as possible through the labrum and capsule close to 6 o'clock position to form the 2 limbs of the first mattress suture...

Adinun Apivatgaroon, Michael Dienst
Assessment of integrity of the acetabular labrum is generally done via the central compartment under distraction of the femoral head from the acetabulum. With the technique of raising the extra-articular and peripheral compartment first, there is a need for testing the stability and function of the labrum from the peripheral side in a nondistracted position of the joint. The authors report on the compression and flip test (i.e., the flip test) for the detection of unstable, intrasubstance tears of the labrum or unstable chondrolabral separations...

PURPOSE: This study aimed to demonstrate the prevalence of lesions in the biceps pulley complex in a representative, consecutive series of rotator cuff tears and rotator cuff interval treatments. We also analyzed associated tear pattern of rotator cuff injuries and superior labrum anterior-posterior (SLAP) lesions. We evaluated the relationships of these lesions to traumatic genesis and the prevalence of pulley lesions in revision cases. METHODS: This retrospective study analyzed all pre- and intra-operative documentation on arthroscopic rotator cuff reconstructions and isolated pulley lesion treatments performed by a single surgeon over 2 consecutive years...

BACKGROUND: Failure of closed manipulative reduction of an acute anterior shoulder dislocation is seldom reported in the literature and is usually due to structural blocks such as soft tissue entrapment (biceps, subscapularis, labrum), bony fragments (glenoid, greater tuberosity) and severe head impaction (Hill-Sachs lesion). CASE REPORT: We present a case of an irreducible anterior shoulder dislocation in a 57-year-old male patient after a road-traffic accident...

Recently, more attention has been paid to the role of the acetabular labrum. Therefore, we designed a retrospective cohort study of patients with residual hip dysplasia (RHD) who underwent magnetic resonance imaging (MRI). The objective of this study was to investigate an association between the MRI appearance of the labrum before school age and the natural history of RHD.We retrospectively investigated 45 hips of 40 patients who underwent MRI at about 3 and 4 years of age for RHD and were conservatively followed up with until 6 years of age or older...

A large portion of persons who commit elder mistreatment have long been known to have indicators of substance abuse and/or mental health conditions (SAMHC). However, few studies have specifically examined elder mistreatment by persons with SAMHC, preventing the development of specialized intervention strategies. Using results from the National Elder Mistreatment Study, the current article examines victim, perpetrator, and interaction characteristics between cases of emotional and physical elder mistreatment in which the perpetrator is reported to have vs...

BACKGROUND: In situ pinning of slipped capital femoral epiphysis (SCFE) results in various degrees of deformity of the femoral head-neck junction. Repetitive trauma from cam-type femoroacetabular impingement (FAI) can lead to labral tears and injury to the articular cartilage causing loss of function. Arthroscopic osteoplasty is an alternative to open procedure and to Southwick/Imhäuser-type osteotomies in symptomatic selected cases. SURGICAL TECHNIQUE: The amount of bone to be resected has to be carefully planned pre-operatively...

INTRODUCTION: The rate of iterative arthroscopy has been increasing over the last decade as the technique has grown. The results of and reasons for these revision procedures, however, are not exactly known. We therefore conducted a prospective study to shed light on: 1) functional results and patient satisfaction following repeated arthroscopy, and 2) the relevant indications. HYPOTHESIS: Functional scores and patient satisfaction increase following repeated arthroscopy...

BACKGROUND: Developmental dysplasia of the hip is an important disease leading to osteoarthritis. Recently, researchers have focused on hip instability as a potentially important dynamic factor for osteoarthritis, but the detailed kinematics of dysplastic hips during weight-bearing gait have not been reported. The purpose of this research is to contrast femoral translation in contralateral healthy hips and dysplastic hips during weight-bearing stepping. METHODS: Twelve dysplastic hips and eight healthy hips were investigated...
