In this study we evaluated whether the Instability
Severity Index Score (ISIS) and the Western Ontario Shoulder Instability
Index (WOSI) could detect those patients at risk of failure following
arthroscopic Bankart repair. Between April 2008 and June 2010, the
ISIS and WOSI were recorded pre-operatively in 110 patients (87
male, 79%) with a mean age of 25.1 years (16 to 61) who underwent
this procedure for recurrent anterior glenohumeral instability. A telephone interview was performed two-years post-operatively
to determine whether patients had experienced a recurrent dislocation
and whether they had returned to pre-injury activity levels. In
all, six (5%) patients had an ISIS >
6 points (0 to 9). Of 100 (91%)
patients available two years post-operatively, six (6%) had a recurrent dislocation,
and 28 (28%) did not return to pre-injury activity. No patient who
dislocated had an ISIS >
6 (p = 1.0). There was no difference in
the mean pre-operative WOSI in those who had a re-dislocation and
those who did not (p = 0.99). The pre-operative WOSI was significantly
lower (p = 0.02) in those who did not return to pre-injury activity, whereas
the ISIS was not associated with return to pre-injury activity (p
= 0.13). In conclusion, neither the pre-operative ISIS nor WOSI predicted
recurrent dislocation within two years of arthroscopic Bankart repair.
Patients with a lower pre-operative WOSI were less likely to return
to pre-injury activity. Cite this article:
Aims. The open Latarjet procedure is a widely used treatment for recurrent anterior instability of the shoulder. Although satisfactory outcomes are reported, factors which influence a patient’s experience are poorly quantified. The aim of this study was to evaluate the effect of a range of demographic factors and measures of the severity of instability on patient-reported outcome measures in patients who underwent an open Latarjet procedure at a minimum follow-up of two years. Methods. A total of 350 patients with anterior instability of the shoulder who underwent an open Latarjet procedure between 2005 and 2018 were reviewed prospectively, with the collection of demographic and psychosocial data, preoperative CT, and complications during follow-up of two years. The primary outcome measure was the

We have investigated the outcome of arthroscopic revision surgery for recurrent instability of the shoulder after failed primary anterior stabilisation. We identified 40 patients with failed primary open or arthroscopic anterior stabilisation of the shoulder who had been treated by revision arthroscopic capsulolabral reconstruction and followed up for a mean of 36 months (12 to 87). There were 34 men and six women with a mean age of 33.1 years (15 to 48). Details of the patients, the technique of the primary procedure, the operative findings at revision and the clinical outcome were evaluated by reviewing the medical records, physical examination and the use of the
We reviewed the outcome of arthroscopic stabilisation of anterior glenohumeral instability in young adults using the transglenoid suture technique. A questionnaire was sent to 455 consecutive patients who had undergone this procedure between 1992 and 2000. Of these, 312 patients (68.5%) with 313 affected shoulders and a mean age of 20 years (18 to 28) responded. Outcome was determined by the number of re-dislocations or, in patients who had not re-dislocated, by the disease-specific quality of life as measured by the
The aim of this study was to determine if the extent of the glenoid and humeral bone loss affects the rate of recurrent instability and the functional outcome following the Latarjet procedure. 161 patients underwent open Latarjet procedure during the period 2006–2015 (Mean age 30.0 years, 150t (93.2%) Male, 118 (73.3%) primary procedure). Functional outcome was measured using the
Background: The results of arthroscopic anterior labral (Bankart) repair have been shown to have high failure rate in patients with significant glenoid bone loss. Several reconstruction procedures using bone graft have been described to overcome the bone loss, including autogenous coracoid transfer to the anterior glenoid (Latarjet procedure) as well as iliac crest autograft and tibial allografts. In recent years, trends toward minimally invasive shoulder surgery along with improvements in technology and technique have led surgeons to expand the application of arthroscopic treatment. Purpose: This study aims to perform a retrospective analysis of prospectively collected data to evaluate the clinical and radiological follow up of patient who underwent anatomic glenoid reconstruction using distal tibia allograft for the treatment of shoulder instability with glenoid bone loss at 1-year post operation time point. Between December 2011 and January 2015, 55 patients underwent arthroscopic stabilisation of the shoulder by means of capsule-labral reattachment to glenoid ream and bony augmentation of glenoid bone loss with distal tibial allograft for recurrent instability of the shoulder. Preoperative and postoperative evaluation included general assessment by the
Purpose: Performing a labral repair alone in patients with recurrent anterior instability and a large glenoid defect has led to poor outcomes. We present a technique involving the use of iliac crest allograft inserted into the glenoid defect in athletes with recurrent anterior shoulder instability and large bony defects of the glenoid (>
25% of glenoid diameter) We hypothesized that restoring a near-normal glenoid structure would prevent further dislocations and that osseous union would be achieved. Method: All athletes with recurrent anterior shoulder instability and a large glenoid defect who underwent open anterior shoulder stabilization and glenoid reconstruction with iliac crest allograft were prospectively followed over a three year period. Pre-operatively, a detailed history and physical exam was obtained along with radiographs, a CT scan, and magnetic resonance imaging of the affected shoulder. All patients also complete the Simple Shoulder Test (SST) and American Shoulder and Elbow Surgeons (ASES) evaluation forms pre – and post-operatively. A CT scan was again obtained 6 months post-operatively to assess osseous union of the graft, and the patient again when through a physical exam in addition to completing the SST, ASES, and
Purpose: The objective of the study was to perform a prospective evaluation of thermal capsulorraphy for the treatment of multidirectional instability of the shoulder. Summary of Methods: Over a period of two years, 19 patients with multidirectional instability were treated with thermal shrinkage. Fifteen patients had involuntary dislocation and four voluntary. The predominant direction of instability was anterior/inferior in 10, posterior in 5 and multiple directions in 4. Patients were followed for a minimum of two years or until surgical failure and recurrence of symptomatology. Postoperatively patients were immobilised in a sling for a period of 3 weeks and were reviewed at 6 weeks and 3, 6, 9 and 12 months and then at six monthly intervals. The
Purpose: Arthroscopic stabilization for post-traumatic anterior glenohumeral instability is designed to minimize soft tissue dissection while achieving similar or improved outcomes relative to open techniques. This study’s purpose was to determine the rate of post-operative recurrent instability and evaluate health related quality of life (HRQL) and shoulder range of motion (ROM) following arthroscopic Bankart repair using a bioabsorbable knotless implant. Method: Forty-three patients were prospectively evaluated following arthroscopic anterior stabilization to assess for recurrent instability, HRQL, and shoulder ROM. Assessments were performed pre-operatively and 3, 6 and 12–24 months postoperatively. The HRQL measures included the
The primary objective of this study was to establish a safety profile for an all-arthroscopic anatomic glenoid reconstruction via iliac crest autograft augmentation for the treatment of shoulder instability with glenoid bone loss. Short-term clinical and radiological outcomes were also evaluated. This study involved a retrospective analysis of prospectively collected data for 14 patients (male 8, female 6) who were treated for shoulder instability with bone loss using autologous iliac crest bone graft between 2014 and 2018. Of 14 patients, 11 were available for follow-up. The safety profile was established by examining intra-operative and post-operative complications such as neurovascular injuries, infections, major bleeding, and subluxations. Assessment of pre-operative and post-operative
This study aimed to quantify the shoulder kinematics during an apprehension-relocation test in patients with anterior shoulder instability (ASI) and glenoid bone loss using the radiostereometric analysis (RSA) method. Kinematics were compared with the patient’s contralateral healthy shoulder. A total of 20 patients with ASI and > 10% glenoid bone loss and a healthy contralateral shoulder were included. RSA imaging of the patient’s shoulders was performed during a repeated apprehension-relocation test. Bone volume models were generated from CT scans, marked with anatomical coordinate systems, and aligned with the digitally reconstructed bone projections on the RSA images. The glenohumeral joint (GHJ) kinematics were evaluated in the anteroposterior and superoinferior direction of: the humeral head centre location relative to the glenoid centre; and the humeral head contact point location on the glenoid.Aims
Methods
To systematically review the predominant complication rates and changes to patient-reported outcome measures (PROMs) following osteochondral allograft (OCA) transplantation for shoulder instability. This systematic review, following PRISMA guidelines and registered in PROSPERO, involved a comprehensive literature search using PubMed, Embase, Web of Science, and Scopus. Key search terms included “allograft”, “shoulder”, “humerus”, and “glenoid”. The review encompassed 37 studies with 456 patients, focusing on primary outcomes like failure rates and secondary outcomes such as PROMs and functional test results.Aims

Purpose. This prospective, expertise-based randomized clinical trial compares arthroscopic to open shoulder stabilization by measuring the disease-specific quality of life outcome in patients with traumatic unidirectional anterior shoulder instability, and determining the incidence of recurrent instability at 2-years post-operatively. Method. One hundred and ninety-six patients were randomly allocated to arthroscopic (n=98) or open (n=98) repair using an expertise-based approach with a surgeon specializing in one type of surgery. Randomization was performed using computer-generation, variable block sizes and concealed envelopes. Outcomes were measured at baseline, 3 and 6 months, 1 and 2 years post-operatively. These outcomes included the
Purpose. Electrothermal arthroscopic capsulorrhaphy (ETAC) was a technology introduced for orthopaedic surgery without good scientific clinical evidence supporting its use. This multicentre randomized clinical trial provides the scientific clinical evidence comparing ETAC to Open Inferior Capsular Shift (ICS), by measuring disease-specific quality of life at 2-years post-operatively, in patients with shoulder instability due to capsular redundancy. Method. Fifty-four subjects (37 females and 17 males; mean age 23.3 years (SD = 6.9; 15–44 years) with multidirectional instability (MDI) or multidirectional laxity with antero-inferior instability (MDL-AII) were randomized intra-operatively to ETAC (n = 28) or Open ICS (n = 26) using concealed envelopes, computer-generated, variable block randomization with stratification by surgeon and type of instability. Outcomes were measured at baseline, 3 and 6 months, 1 and 2 years. The

Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from screw fixation to metal-free fixation. The new arthroscopic techniques of glenoid bone reconstruction procedures allow precise positioning of the graft, identification, and treatment of concomitant injuries with low morbidity and faster recovery. Given the problems associated with bone resorption and metal hardware protrusion, the new metal-free techniques for Latarjet or free bone block procedures seem a good solution to avoid these complications, although no long-term data are yet available.
