Scoring systems for shoulder conditions.

Background Arthroscopic stabilization for anterior shoulder instability has been reported to result in a higher rate of recurrent instability compared to traditional open techniques. Purpose To test the null hypothesis that there is no difference in the clinical outcomes in patients with recurrent anterior shoulder instability treated with open or arthroscopic stabilization. Study Design Randomized controlled trial; Level of evidence, 1. Methods A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Magnetic resonance arthrogram studies were obtained preoperatively. These findings were compared to arthroscopic findings. Postoperative evaluations included range of motion, stability, and subjective assessments including Single Assessment Numeric Evaluation, Simple Shoulder Test, Western Ontario Instability Index, and University of California, Los Angeles evaluation. Failure was defined as a second dislocation, recurrent subluxation, or symptoms precluding return to previous work or unrestricted active military duty. Results Sixty-one patients, 29 who received open stabilization and 32 who received arthroscopic stabilization, were evaluated at a mean of 32 months postoperatively (range, 24-48 months). Patient demographics were equivalent. Preoperative magnetic resonance arthrogram findings were confirmed at arthroscopic examination. The mean operative time was significantly shorter for the arthroscopic repairs (59 vs 149 minutes; P <. 001). There were 3 clinical failures (2 open stabilizations, 1 arthroscopic stabilization) by the established criteria. There was a statistically significant improvement from preoperative to postoperative Single Assessment Numeric Evaluation scores in both groups (P <. 001). The mean loss of motion (compared to the contralateral shoulder) was greater in the open shoulders. Subjective evaluations were equal in both groups. Conclusion Clinical outcomes after arthroscopic and open stabilization were comparable. Preoperative magnetic resonance arthrograms in shoulders with anterior instability allow an accurate diagnosis of intra-articular abnormality that correlates well with operative findings. Arthroscopic stabilization for recurrent anterior shoulder instability can be performed safely; the clinical outcomes are comparable to those after traditional open stabilization.

Limited Predictive Value of the Instability Severity Index Score: Evaluation of 217 Consecutive Cases of Recurrent Anterior Shoulder Instability

Mid- to long-term results of postoperative immobilization in internal vs. external rotation after arthroscopic anterior shoulder stabilization.

BackgroundArthroscopic stabilization of torn coracoclavicular (CC) ligaments gained popularity recently. However, loss of reduction after the operation and complications unique to this technique involving tunnel placement through the distal clavicle and coracoid process are concerns. The purpose of this study was to report intraoperative and early postoperative complications associated with this procedure.MethodsThis study retrospectively evaluated 18 consecutive patients who had undergone arthroscopic stabilization for torn CC ligaments between 2014 and 2015. The indications for surgery were acute or chronic acromioclavicular dislocation and acute fracture of the distal clavicle, associated with CC ligament disruption. Clinical outcomes were evaluated with the American Shoulder and Elbow Surgeons (ASES) and the University of California, Los Angeles (UCLA) scores. Intra- and postoperative complications and reoperations were investigated.ResultsThere were six female and 12 male patients with a mean age of 47 years (range, 22 to 86 years). At a mean follow-up of 17 ± 10 months (range, 10 to 28 months), the mean ASES score was 88.8 ± 19.9 and the mean UCLA score was 30.9 ± 5.2. Intraoperatively, seven complications developed: breach of lateral cortex of the coracoid process in five patients, medial cortex of the coracoid process in one, and anterior cortex of the clavicle in one. Postoperative complications developed in eight patients: four ossifications of the CC interspace, four tunnel widening of the clavicle, one bony erosion on the clavicle, and one superficial infection. A loss of reduction was found in six patients. Reoperation was performed in three patients for loss of reduction in two and superficial infection in the other.ConclusionsArthroscopic CC stabilization resulted in high rates of intraoperative and early postoperative complications. Most of them were related to the surgical technique involving bone tunnel placement in the coracoid process and the clavicle.

Objectives The objective of this systematic review is to compare the effect of arthroscopic stabilization with open surgical stabilization for the management of traumatic anterior glenohumeral instability. We aim to address the following questions that are of clinical interest: 1. Is arthroscopic stabilization equally effective as open surgical stabilization in the management of anterior glenohumeral instability for: a. The general population? b. Population sub-groups? 2. Are there any differences in the outcome of various arthroscopic techniques (suture anchors, bioabsorbable tacks, transglenoid sutures and metallic fixators) for shoulder stabilization, compared with open surgical stabilization? 3. What factors and prognostic indicators are considered when deciding between arthroscopic versus open surgical stabilization for the management of anterior glenohumeral instability? Criteria for considering studies for this review Types of participants Patients with traumatic anterior glenohumeral instability, confirmed by one or more of the following: a history of trauma precipitating anterior dislocation/subluxation, radiological evidence, clinical examination, examination under anaesthesia (EUA) and arthroscopy will be included. By definition, traumatic anterior glenohumeral instability may include first-time dislocators as well as patients with recurrent dislocations, subluxation or a positive apprehension test. Patient groups that are specifically 40 years and older will be excluded from the study because of a higher rate of associated rotator cuff pathology within this age-group. Patients with multidirectional instability and any other concomitant shoulder pathology will also be excluded to eliminate potential confounding factors that could affect the outcome of the stabilization procedures for the management of traumatic anterior glenohumeral instability. Types of interventions Interventions will include all types of arthroscopic shoulder stabilization techniques such as suture anchors, bioabsorbable tacks, transglenoid sutures and metallic fixators, with or without additional suture plication of the capsule, compared with open surgical shoulder stabilization techniques, for the management of traumatic anterior glenohumeral instability. Studies that applied non-anatomical surgical procedures i.e. Putti-Platt, Bristow will be excluded because, they do not correct the underlying pathological lesion; they alter normal shoulder kinematics; have high complication rates and are infrequently performed in clinical practice today. Types of outcome measures A minimum follow-up period of 2 years will be TRUNCATED AT 350 WORDS

Arthroscopic Stabilization for Recurrent Shoulder Instability With Moderate Glenoid Bone Defect in Patients With Moderate to Low Functional Demand

Objective To discuss the clinical results of arthroscopic treatment of superior labrum anterior posterior (SLAP) lesions of the shoulder. Methods A retrospective study was conducted for the 29 cases of shoulder SLAP lesions who had been treated by arthroscopy from January 2000 to December 2007. They were followed up for a mean period of 26.1(9 to 89) months and evaluated by UCLA (University of California at Los Angeles) and ASES (American Shoulder and Elbow Surgeons) score systems before and after operation. Cases of subacromial impingement syndrome, rotator cuff tear and shoulder dislocation were ex-cluded from this study. Results The SLAP lesions were classified into 9 typos. There were 2 eases of type L 17 cases of type Ⅱ 1 case of type Ⅲ, 3 cases of type Ⅳ, 1 ease of type Ⅴ, 1 ease of type VI, and 4 cases of type Ⅷ. The average preoperative ASES score was 9.19±1.77 and the average preoperative UCLA score was 19.23± 3.88. After the operation, the average ASES score was 16.08±0.94 and the average UCLA score was 33.23± 2.08. The differences before and after surgery were statistically significant (P<0.05). After surgery 25 cases achieved the same sports level as before and reported no complains. Three cases had slightly limited range of movement. In I case, the pain was only lightly alleviated. All the 13 athletes restored the same sports level as before. The reply was positive by all patients to the question: Do you want to accept the same operation if you are injured again? Conclusion Arthreseopic treatment of SLAP lesions is safe and effective. Key words: Shoulder joint; Arthroseopy; Superior labrum anterior posterior (SLAP) lesions

Both total shoulder arthroplasty and hemiarthroplasty have been used commonly to treat severe osteoarthritis of the shoulder; however, their effect on disease-specific quality-of-life outcome is unknown. The purpose of this study was to compare the quality-of-life outcome following hemiarthroplasty with that following total shoulder arthroplasty in patients with osteoarthritis of the shoulder. Forty-two patients with a diagnosis of osteoarthritis of the shoulder were randomized to receive a hemiarthroplasty or a total shoulder arthroplasty. One patient died, and all others were evaluated preoperatively and at six weeks and three, six, twelve, eighteen, and twenty-four months postoperatively with use of a standardized format including a disease-specific quality-of-life measurement tool (Western Ontario Osteoarthritis of the Shoulder [WOOS] index), general shoulder rating scales (University of California at Los Angeles [UCLA] shoulder scale, Constant score, and American Shoulder and Elbow Surgeons [ASES] evaluation form), general pain scales (McGill pain score and visual analogue scale), and a global health measure (Short Form-36 [SF-36]). When a patient required revision of a hemiarthroplasty to a total shoulder arthroplasty, the last score before he or she "crossed over" was used for the analysis. Significant improvements in disease-specific quality of life were seen two years after both the total shoulder arthroplasties and the hemiarthroplasties. There were no significant differences in quality of life (WOOS score) between the group treated with total shoulder arthroplasty and that treated with hemiarthroplasty (90.6 +/- 13.2 and 81.5 +/- 24.1 points, respectively; p = 0.18). The other outcome measures demonstrated similar findings. Two patients in the hemiarthroplasty group crossed over to the other group by undergoing a revision to a total shoulder arthroplasty because of glenoid arthrosis. Both total shoulder arthroplasty and hemiarthroplasty improve disease-specific and general quality-of-life measurements. With the small number of patients in our study, we found no significant differences in these measurements between the two treatment groups. Therapeutic Level I.

Suture Anchors Are Superior to Transglenoid Sutures in Arthroscopic Shoulder Stabilization

Revision Arthroscopic Rotator Cuff Repair: A Prospective Study (SS-13)

The goal for arthroscopic stabilization of anterior glenohumeral instability is to achieve an outcome equivalent to or better than open procedures. A number of arthroscopic procedures have been advocated to reestablish continuity of the inferior glenohumeral ligament complex (IGHLC) with the glenoid. Implantable suture anchors were developed to avoid the problems associated with arthroscopic staple capsulorrhaphy like iatrogenic injury of the glenoid or humeral surface, loosening and migration of the staple. Several transosseous techniques include the need for an accessory posterior incision, the possibility of neurovascular injury (Suprascapular or axillary nerve), and the loosening of the repair after tying over the fascia of the infraspinatus posteriorly. The preferred techniques are cannulated, absorbable fixation device (Suretac) and easy implantable suture anchors made of titanium (Fastak). Even in the hands of experienced arthroscopists, unacceptably high recurrence rates for arthroscopic shoulder stabilization have been reported, due to the steep learning curve for both technical performance and patient selection. Our experience suggests, that if proper selection criteria are employed, normal patients and overhead-athletes may benefit from the advantages of an arthroscopic repair without accepting an increased risk for recurrence. We performed a prospective analysis of 105 shoulders, who underwent arthroscopic stabilization with Suretac or Fastak between 4/96 and 7/98. 48 shoulders were available for followup at least one year. The redislocation rate was 6.25 % (3 shoulders) and the rate of subluxation without dislocation also was 6.25 %, but none of the shoulders required a second open stabilization. The reason for redislocation or subluxation were 5/6 traumatic injuries, participating in contact sports or in one case a generalized ligamentous laxity. In combination with the LACS-Procedure or the Electro thermally assisted capsular shift (ETACS) not only the capsular detachment but also the capsular redundancy may be adressed and a lower failure rate can be expected.

Limited knowledge exists regarding prognostic factors after rotator cuff repair. To identify pre- and perioperative predictors for functional outcomes after arthroscopic rotator cuff repair. Case-control study; Level of evidence, 3. This study included patients who underwent arthroscopic rotator cuff repair between January 2013 and April 2019 and who had preoperative magnetic resonance imaging scans. The procedures were performed by 4 shoulder surgeons at a single institution. Excluded were patients who had previous surgeries, those who underwent open surgery, and those without 12- and 24-month follow-up clinical data. Patient-reported outcomes (American Shoulder and Elbow Surgeons [ASES] Standardized Shoulder Assessment Form and University of California, Los Angeles [UCLA] Shoulder Rating Scale scores) were assessed preoperatively and at 6, 12, and 24 months postoperatively. Using multiple linear regression analysis, the authors evaluated the influence of 29 variables relating to patient, lesion, and procedure characteristics on postoperative outcomes, with the 24-month ASES score as the dependent variable. The study sample consisted of 474 patients (500 shoulders). The median ASES score increased from 41.6 preoperatively to 88.3 at 24 months (P < .001), and the median UCLA score increased from 14 preoperatively to 32 in the same period (P < .001). The following variables were found to be independent predictors for higher 24-month postoperative ASES score: male sex, absence of rheumatologic disease, older age, lower degree of supraspinatus muscle fatty degeneration, acromioplasty, and a higher preoperative ASES score. The prognostic factors for better clinical results at 24 months after arthroscopic rotator cuff repair were male sex, absence of rheumatologic disease, older age, lower degree of fatty degeneration of the supraspinatus muscle, concomitant acromioplasty, and higher preoperative ASES score.

To evaluate the clinical efficacy and safety of clavicular anatomical plate in the treatment of clavicular Allmanic fracture. Between January 2016 and December 2022, 27 patients with Allman ⅡC distal clavicle fractures were treated with clavicular anatomical plate. There were 19 males and 8 females, aged from 16 to 69 years old, with an average of (39.74±12.71) years old. There were 15 patients on the left side and 12 patients on the right side. There were 15 patients with single clavicle fracture and 12 patients complicated with other parts of the body or organ injury. The broken ends of the fractures were fixed with clavicular anatomical plate, including common compression clavicular anatomical plate in 19 patients and locking clavicular anatomical plate in 8 patients. The operation time and hospitalization days were recorded. Visual analogue scales (VAS) were utilized to assess subjective pain levels both preoperatively and 3 days postoperatively. Postoperatively, patients were monitored at intervals of 1 to 3 months until X-ray films confirmed fracture healing. In accordance with the University of California, Los Angeles (UCLA) shoulder rating system, evaluations were conducted on postoperative pain alleviation, functional recovery, range of motion in forward flexion, strength in forward flexion, and patient satisfaction. All patients were followed up for a period ranging from 12 to 18 months with an average of (14.70±1.61) months, and all clavicular fractures achieved successful union. The wounds of 24 patients healed in one stage, and 3 patients developed bleeding and exudation, they were cured after dressing change. There were no complications such as infection, plate and screw fracture, vascular and nerve injury. The operation time was(67.56±11.01) min. Significant differences were observed in pain relief, functional improvement, range of motion for forward flexion, strength of forward flexion, patient satisfaction, and overall scores at preoperative, 3 months postoperatively, 6 months postoperatively, and at the final follow-up(P<0.001). The utilization of clavicular anatomical plates for the management of Allman typeⅡC fractures can provide early and stable fixation without compromising the acromioclavicular joint, thereby enabling patients to commence early mobilization and ensuring optimal fracture healing.

Objectives: Surgical options for shoulder instability in collision athletes remain controversial. Although arthroscopic soft tissue stabilization is widely accepted treatment for shoulder instability, many surgeons prefer coracoid transfer for collision athletes with or without glenoid defect due to potential high recurrence rate after arthroscopic soft tissue Bankart repair (ABR). In the meantime, Hill-Sacks remplissage (HSR) has been gaining popularity as an effective arthroscopic augmentation procedure. Since 2002, we performed rotator interval closure (RIC) as an augmentation in addition to ABR or arthroscopic bony Bankart repair (ABBR) for collision athletes and obtained satisfactory outcome. However, teen players demonstrated higher recurrence rate compared to twenties and thirties. Therefore, from 2012, we performed HSR as an additional augmentation for teen players besides ABR/ABBR and RIC. The purpose of this study was to assess the outcomes after arthroscopic stabilization in collision athletes who underwent shoulder stabilization under our treatment strategy. Methods: Between 2012 through 2015, 95 consecutive collision athletes underwent shoulder stabilization. Among those, only 2 patients (2%) underwent arthroscopic bony procedure for poor capsular integrity. Among the remaining 93 patients who underwent soft tissue stabilization, 65 were available for minimum 2 year follow-up (70%). Therefore, subjects consisted of 65 players including 54 rugby and 11 American football players (Table 1). There were 13 national top league, 24 collegeate, 21 junior or senior high school, and 7 recreational players. The mean age at surgery was 20 years (range, 16-36). The mean follow-up was 37 months (range, 24-64). We retrospectively reviewed intraoperative findings and surgical procedures using patient records including surgical reports and videos. We also investigated the mean time for sports return, functional outcome and recurrence rate. Pre- and postoperative Rowe scores were compared using paired t test. Results: Preoperative 3DCT of the glenoid demonstrated bony Bankart (fragment type) in 43 players (66%), attritional type in 16 (25%), and normal glenoid in 6 (9%). Mean glenoid bone loss was 15% (range, 0-25) and all of the glenoid with more than 10% bone loss retained bony fragment (Table 2). All 65 players demonstrated Bankart lesion and 15 had concomitant SLAP lesion (23%) which required repair. In addition, 5 players demonstrated capsule tear (8%), which were also repaired. Twenty four players (36%) underwent ABR or ABBR with RIC and forty one players (64%) underwent ABR or ABBR combined with HSR (Table 1).The mean time for sports return was 7 months (range, 4-13) after surgery. The mean Rowe score significantly improved after surgery from 65 (range, 55-75) to 92 (range, 65-100) (P &lt; .001). Recurrence appeared in 2 cases (3%), both of which were junior or senior high school players who underwent ABR with HSR. Conclusion: Soft tissue stabilization combined with selective augmentation procedures for shoulder instability in collision athletes demonstrated satisfactory outcomes with low recurrence rate. Since the incidence of having bony Bankart lesion in collision athletes was very high, arthroscopic bony Bankart repair worked in many patients even with significant glenoid bone loss. Further, HSR seemed to be effective additional augmentation especially in young collision athletes. [Table: see text][Table: see text]
