PURPOSE The purpose of this study was to compare the forearm supination and elbow flexion strength of the upper extremity in patients who have had an arthroscopic long head of the biceps tendon (LHBT) release with patients who have had an LHBT tenodesis. METHODS Cybex isokinetic strength testing (Cybex Division of Lumex, Ronkonkoma, NY) was performed on(More)
Several types and subtypes of vocalizations which have a behavioral impact on degu pups were identified. Among these the complex “mothering call” which is exclusively uttered by females and first during extensive nursing periods in the nest is a candidate for filial learning. In 14C-2-fluoro-2-deoxyglucose (FDG) experiments two-weeks-old pups raised by(More)
Lesions of the long head biceps tendon (LHB) are frequent causes of shoulder pain and disability. Biceps tenotomy and tenodesis have gained widespread acceptance as effective procedures to manage both isolated LHB pathology and combined lesions of the rotator cuff and biceps-labral complex. The function of the LHB tendon and its role in glenohumeral(More)
To evaluate whether isolated anatomical coracoclavicular (CC) ligament reconstruction with two suture-button devices provides equal horizontal acromioclavicular joint (ACJ) stability compared to additional ACJ suture tape cerclage. A servohydraulic testing machine was used to assess horizontal ACJ translation in 12 fresh-frozen human shoulders during 5,000(More)
BACKGROUND Bioabsorbable interference screw fixation has superior biomechanical properties compared to suture anchor fixation for biceps tenodesis. However, it is unknown whether fixation technique influences clinical results. HYPOTHESIS We hypothesize that subpectoral interference screw fixation offers relevant clinical advantages over suture anchor(More)
Arthroscopic treatment of bony Bankart lesions can be challenging. We present a new easy and reproducible technique for arthroscopic reduction and suture anchor fixation of bony Bankart fragments. A suture anchor is placed medially to the fracture on the glenoid neck, and its sutures are passed around the bony fragment through the soft tissue including the(More)
BACKGROUND Symptomatic Acromioclavicular (AC) dislocations have historically been surgically treated with Coracoclavicular (CC) ligament reconstruction with transfer of the Coracoacromial (CA) ligament. Tensioning the CA ligament is the key to success. METHODS Seventeen patients with chronic, symptomatic Type III AC joint or acute Type IV and V injuries(More)
BACKGROUND Lesions of the biceps pulley and instability of the long head of the biceps tendon are common diagnoses in patients with anterior shoulder pain. PURPOSE To analyze the pathoanatomy of the biceps reflection pulley ("pulley") in consecutive patients undergoing shoulder arthroscopy. STUDY DESIGN Cohort study (prevalence); Level of evidence, 2.(More)
Chondral or osteochondral lesions are typical injuries in orthopaedics and traumatology. Since there is no regeneration of damaged articular cartilage, these lesions can lead to premature osteoarthritis. Therefore, an adequate therapy for these injuries is an important goal. Nowadays, common methods in cartilage therapy are procedures for the recruitment of(More)
This is a review of joint-preservation techniques for the shoulder. Whereas the management of diffuse articular cartilage loss in the glenohumeral joints of elderly and less active patients by total shoulder arthroplasty is well accepted, significant controversy persists in selecting and refining successful operative techniques to repair symptomatic(More)
