PURPOSE: Recent techniques for acromioclavicular (AC) joint reconstruction focus on additional AC cerclage to coracoclavicular (CC)-reconstructions. Due to the specific slim bone morphology at the acromion, there are concerns regarding these additional bone tunnels, as they may predispose to fracture and break out. The purpose of this study was to investigate anatomic properties of the acromion which may help improve surgical techniques directed at injuries to the AC joint. It was hypothesized that via measurements of thickness and density points of increased strength and support could be identified on the acromion...

Objective To explore the clinical value of indocyanine green (ICG) for the fluorescence-guided detection of sentinel lymph nodes (SLNs) during sentinel lymph node biopsy (SLNB) in patients with early breast cancer. Methods This retrospective study included female patients with breast cancer. Patients were administered methylene blue and ICG using standard techniques. All SLNs that were collected during surgery were submitted for pathological examination. SLNs were defined as those that were either fluorescent, blue, fluorescent and blue or palpably suspicious...

BACKGROUND: Numerous surgical options for the management of engaging Hill-Sachs lesions exist, of which remplissage has emerged as one of the most popular arthroscopic techniques. Remplissage is not without disadvantages, however, and has been demonstrated to potentially result in a loss of external rotation (ER) due to nonanatomic tethering of the infraspinatus tendon and a potential decrease in infraspinatus strength clinically. PURPOSE: The efficacy of posterior medial capsular plication in addition to Bankart repair was examined as an arthroscopic management strategy for an engaging Hill-Sachs defect...

Objective.:  Primary adhesive capsulitis (AC), or frozen shoulder, is an insidious and idiopathic disease. Severe pain is predominant in the first two of the three stages of the condition, which can last up to 21 months. Design, Setting, and Subjects.:  Sixty volunteers with primary AC were randomly assigned to acupuncture with press tack needles compared with press tack placebos in a patient- and observer-blinded placebo-controlled study. The participants were subsequently offered classical needle acupuncture in an open follow-up clinical application...

HYPOTHESIS: The objective of this study was to determine the biomechanical function of the rotator cable when a partial-thickness (>50%) tear is present. We compared intact specimens with partial tears of the anterior cable followed by partial anterior and posterior tears in regard to glenohumeral kinematics and translation. The hypothesis was that partial-thickness tears will lead to abnormal glenohumeral biomechanics, including glenohumeral translation and path of glenohumeral articulation...

BACKGROUND: Recent studies have identified the diagnostic challenge of low-grade infections after shoulder arthroplasty surgery. Infections after nonarthroplasty procedures have not been reported. This study assessed patient-related risk factors, outcomes, and clinical presentation of low-grade infection after open and arthroscopic nonarthroplasty shoulder surgery. METHODS: The cases of 35 patients presenting with suspected low-grade infection were reviewed. Biopsy specimens taken at revision surgery were cultured in the sterile environment of a class II laminar flow cabinet and incubated for a minimum of 14 days at a specialist orthopedic microbiology laboratory...

PURPOSE: To characterize the tensile and histologic properties of the anterolateral ligament (ALL), inferior glenohumeral ligament (IGHL), and knee capsule. METHODS: Standardized samples of the ALL (n = 19), anterolateral knee capsule (n = 15), and IGHL (n = 13) were isolated from fresh-frozen human cadavers for uniaxial tensile testing to failure. An additional 6 samples of the ALL, capsule, and IGHL were procured for histologic analysis and determination of elastin content...

BACKGROUND: In this study, coracohumeral ligament (CHL) specimens were carefully dissected to observe its length, width, thickness and tension at different positions of the shoulder joint, thereby elucidating its effects on shoulder joint stability. MATERIALS AND METHODS: Fresh frozen shoulder joints from 40 normal adult cadaveric specimens were dissected to reveal the CHL. With the shoulder joints placed at different positions, the length of the CHL and the width and thickness of the middle part of the ligament were measured...

Latissimus dorsi tendon transfer is a surgical option for treating irreparable posterosuperior rotator cuff tears, notably when attempting to reconstruct active external rotation. We hypothesized that the positioning of the transfer's point of fixation would differ depending on the desired elbow-to-body external rotation or external rotation with the elbow abducted. MATERIAL AND METHODS: Seven shoulders from four whole frozen cadavers were used. We created two systems to install the subject in a semi-seated position to allow external rotation elbow to body and the arm abducted 90°...

BACKGROUND: A retear is a significant clinical problem after rotator cuff repair. However, no study has evaluated the retear rate with regard to the extent of footprint coverage. PURPOSE: To evaluate the preoperative and intraoperative factors for a retear after rotator cuff repair, and to confirm the relationship with the extent of footprint coverage. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data were retrospectively collected from 693 patients who underwent arthroscopic rotator cuff repair between January 2006 and December 2014...

Paul M Robinson, Jennie Norris, Christopher P Roberts
HYPOTHESIS AND BACKGROUND: Hydrodilatation and physiotherapy are commonly used treatments for primary frozen shoulder. Little is known about the optimal form of physiotherapy. This study reports a randomized controlled trial comparing 2 forms of physiotherapy after hydrodilatation. The null hypothesis was that there would be no difference between the 2 groups at 1 year as measured by the Oxford Shoulder Score (OSS). METHODS: We randomized 41 patients undergoing hydrodilatation for primary frozen shoulder into 2 treatment groups: group 1 (n = 20) underwent supervised physiotherapy in addition to a home exercise program, and group 2 (n = 21) followed a self-directed home exercise program in isolation...

Ultrasound-guided regional anesthesia (UGRA), like other basic skills, should be learnt in a simulation laboratory before performing on the patient. Cadavers provide an ideal tool for learning sonoanatomy and skills required for performing UGRA. On the basis of preservation technique used, the cadavers can be formalin embalmed cadavers, Thiel cadavers (soft cadavers), and fresh frozen cadavers. We compared three types of cadavers for performing ultrasound-guided upper and lower limb blocks. We observed that fresh frozen and Thiel cadavers were less smelling and had more realistic appearance as compared to formalin embalmed cadavers...

INTRODUCTION: Previous studies have described a segment of the axillary nerve (AN) that cannot be surgically explored through standard open surgical approaches (blind zone). This study aimed to evaluate the feasibility of combining the standard posterior approach to the AN by using an arthroscope to visualize all segments of the AN. MATERIAL AND METHODS: Four fresh-frozen shoulders in two adult human torsos were included in the study. A standard posterior approach was performed on each shoulder, and a dry arthroscopy was performed through the surgical opening in an attempt to visualize all the segments of the AN...

Axillary nerve injury is a risk of the deltopectoral approach to the proximal humerus. The anterior motor branch is potentially vulnerable during subdeltoid dissection. Insertion of the pectoralis major tendon is an easily identifiable landmark on the humerus. This anatomical study explored whether the superior aspect of the pectoralis major tendon is a useful landmark for localizing the anterior motor branch of the axillary nerve as it travels under the lateral and anterior deltoid muscle. A total of 30 fresh-frozen human bilateral cadaveric upper extremities were examined...

PURPOSE: To investigate the biomechanical performance of four different methods used for coracoclavicular (CC) ligament reconstruction in a lateral clavicle fracture repair. METHODS: Native displacement, translation, and rotation at the acromioclavicular joint of 24 fresh-frozen cadaveric shoulders were tested. A reproducible fracture in the lateral third of the clavicle was created by dissecting both CC ligaments. Each specimen was then repaired with plate fixation of the fracture and the following CC repair technique: (1) Cortical button...
