BackgroundThe Latarjet and iliac crest bone graft transfer (ICBGT) procedures are competing treatment options for anterior shoulder instability with glenoid loss.MethodsIn this bicentric prospective randomized study, 60 patients loss were included to either an open or ICBGT (J-bone graft) procedure. Clinical evaluation was completed before surgery 6, 12, 24 months after surgery, including the Western Ontario Shoulder Instability index, Rowe score, Subjective Value, pain level, satisfaction...
Background: Arthroscopically assisted single-bundle (SB) or double-bundle coracoclavicular (CC) ligament reconstruction using autologous tendon grafts has been reported to provide acromioclavicular (AC) joint (ACJ) stability in chronic instability cases. Recently, additional AC triple-bundle (TB) stabilization introduced but lacks a comparison of clinical and radiological outcomes. Hypothesis: anatomic TB CC yields superior results when compared with nonanatomic SB reconstruction. Study...
Background/Objectives: Classical reverse shoulder arthroplasty (RSA) with a high neck-shaft angle (NSA) of 155° has shown satisfactory outcomes. However, newer RSA designs aim to improve results by modifying the stem design. This study evaluates 5-year outcomes design featuring rectangular metadiaphyseal fixation and 135° NSA. Methods: prospective bicentric case series included longitudinally followed up patients that were treated for cuff arthropathy, massive irreparable rotator tears, or...
Acromial morphology has previously been defined as a risk factor for some shoulder pathologies. Yet, study results are inconclusive and not all major diseases have sufficiently investigated. Thus, the aim of present was to analyze predictive value three radiological parameters including critical angle, acromion index, lateral angle in relationship symptomatic patients with either cuff tear arthropathy, glenohumeral osteoarthritis, rotator tear, impingement, tendinitis calcarea.A total 1000...
Background: Promising short-term outcomes after pectoralis major tendon transfer for the treatment of an irreparable anterosuperior rotator cuff tear have been reported. The purpose this study was to evaluate long-term outcome. Methods: Twenty-seven consecutive patients with tears without advanced arthropathy or humeral head migration were treated a partial subcoracoid between 2004 and 2005. At average 10 years (range, 9 11 years) postoperatively, 22 (82%) age 62 42 74 at time surgery had...
Pathologic activation pattern of muscles can cause shoulder instability. We propose to call this pathology functional instability (FSI). The purpose prospective study was provide an in-detail description the characteristics FSI.In year 2017, a total 36 consecutive cases FSI presenting our outpatient clinic were prospectively collected. Diagnostic investigation included pathology-specific questionnaire, standardized clinical scores, examination, psychological evaluation, video and dynamic...
Background: Bone loss at the anterior glenoid rim is a main reason for failure of soft-tissue based surgical stabilization procedures in patients with shoulder instability. Purpose: To evaluate capability conventional bone measurement techniques to provide an adequate estimation actual biomechanical effect defects. Study Design: Descriptive laboratory study. Methods: Thirty consecutive unilateral instability and varying degrees defect were included. Patient-specific computer tomography–based...
Arthroscopic rotator cuff repair (RCR) with suture anchor-based fixation techniques has replaced former open and mini-open approaches. Nevertheless, long-term studies are scarce, lack of knowledge exists about whether single-row (SR) or double-row (DR) methods superior in clinical anatomic results.To analyze results after arthroscopic RCR patients symptomatic tears to compare functional radiographic outcomes between SR DR at least 10 years surgery.Cohort study; Level evidence, 3.Between 2005...
Downhill mountain biking (DMB) has become an increasingly popular extreme sport in the last few years with high velocities and bold manoeuvres. The goal of this study was to provide information on pattern causes injuries order starting points for injury prevention measures.We performed a monthly e-mail-based prospective survey 249 riders over one summer season ranging from April until September 2011.A total 494 occurred during 29 401 h downhill exposure recorded, these 65% were mild, 22%...
Neglected osseous glenoid defects are thought to be one of the reasons for reported high rates recurrent instability at long-term follow-up after Bankart repair. We hypothesized that open repair treatment anterior glenohumeral in absence a substantial defect would result lower recurrence rate than has been previous studies.Forty-seven patients were treated with primary modified shoulder between 1989 and 1994. Double-contrast computed tomography scanning was used exclude defect. Forty (85.1%)...
Background: The implant-free, autologous, iliac crest bone graft procedure (J-bone graft) for the treatment of anterior shoulder instability shows low rates recurrent dislocations and moderate progression arthropathy in midterm follow-up. Purpose: To analyze clinical radiological long-term results J-bone procedure. Study Design: Case series; Level evidence, 4. Methods: A total 46 patients (47 shoulders) with a relevant bony glenoid defect who received between 1993 2000 were previously...
BackgroundThe literature suggests implantation of the humeral component in reverse total shoulder arthroplasty (RTSA) 0°-40° retrotorsion without further specification. We hypothesized that optimal to avoid notching and gain balanced rotational capacity would depend on scapular position posture.MethodsWe investigated 200 shoulders 100 patients with available whole-body computed tomography scans created 3-dimensional models. Implantation a 20° was simulated, correction angle (CA) yield...
Background: Pathological muscle activation patterns of the external rotators and periscapular muscles can result in posterior positional functional shoulder instability (PP-FSI). In several patients, physical therapy surgical treatment are not successful. Purpose: The shoulder-pacemaker concept was evaluated prospectively patients with PP-FSI previously failed conventional attempt. Study Design: Case series; Level evidence, 4. Methods: A negative selection 24 consecutive cases...
