Quantification of active ROM after arthroscopic Bankart repair with rotator interval closure

A Novel Technique for Labral Reconstruction Using Long Head of Biceps Tendon: Duru Technique

Arthroscopic capsulolabral repair is a well-established surgical treatment for traumatic anterior shoulder instability. When there is insufficient labral tissue during arthroscopic primary or revision Bankart repairs, various soft tissue procedures have been recommended. All these procedures aim to reattach glenohumeral ligaments to the glenoid rim and regain the tight anterior structures to prevent re-dislocation or subluxation. Some authors recommend the Latarjet procedure, even in the absence of critical bone loss in this patient group. The labrum increases the depth of the glenoid cavity, thereby, increasing the glenoid track. It behaves like a block for the humeral head. Reconstruction of the labral tissue may strongly contribute to shoulder joint stability when it is totally absent. In this article, we describe a novel labral reconstruction technique (Duru technique) using the long head of the biceps tendon in two patients without an existing labral tissue.

Similar functional outcome using single anterior portal and standard two portals technique in recurrent dislocation of shoulder

PURPOSE

Recurrent dislocation of shoulder (RDS) is a common injury in high demand professionals, like athletes and military personnel. The treatment for the patients with Bankart lesion is the arthroscopic repair. This present study compares the outcomes of two different techniques of arthroscopic Bankart repair i.e. a standard two anterior portals technique and a single anterior portal technique in patients with RDS.

METHODS

Patients with traumatic RDS met the inclusion criteria were managed with Bankart repair using either two anterior portals (Group A) or a single anterior portal (Group B) technique. Patients were evaluated before the intervention and at the mean follow-up of approximately two years using Rowe score, Oxford shoulder score and Tegner activity scale.

RESULTS

The mean age of the patients in Groups A (n = 34) and B (n = 37) was 29.64 years and 29.05 years respectively (p = 0.66). The dominant shoulder was involved in 27 patients in Group A and 22 patients in Group B (p = 0.069). The operative time in Group A and B was 68.52 min and 46.35 min, respectively (p < 0.001). The complications at follow-up, the mean Rowe score and Oxford score improved significantly in both groups compared with the pre-operative values. However, the final outcome scores were not significantly different between the both groups. The median Tegner's score preoperatively and at follow-up was 7 and 6, respectively in Groups A and B.

CONCLUSIONS

Single anterior portal technique is an effective treatment modality, yielding a similar outcome as two anterior portals technique in the management of RDS.

Controversies In The Surgical Management Of Shoulder Instability: Associated Soft Tissue Procedures

Background:

The glenohumeral joint is a ball-and-socket joint that is inherently unstable and thus, susceptible to dislocation. The traditional and most common anatomic finding is the Bankart lesion (anterior-inferior capsule labral complex avulsion), but there is a wide variety of anatomic alterations that can cause shoulder instability or may be present as a concomitant injury or in combination, including bone loss (glenoid or humeral head), complex capsule-labral tears, rotator cuff tears, Kim´s lesions (injuries to the posterior-inferior labrum) and rotator interval pathology.

Methods:

A review of articles related to shoulder anatomy and soft tissue procedures that are performed during shoulder instability arthroscopic management was conducted by querying the Pubmed database and conclusions and controversies regarding this injury were exposed.

Results:

Due to the complex anatomy of the shoulder and the large range of movement of this joint, a wide variety of anatomic injuries and conditions can lead to shoulder instability, specially present in young population. Recognizing and treating all of them including Bankart repair, capsule-labral plicatures, SLAP repair, circumferential approach to pan-labral lesions, rotator interval closure, rotator cuff injuries and HAGL lesion repair is crucial to achieve the goal of a stable, full range of movement and not painful joint.

Conclusion:

Physicians must be familiarized with all the lesions involved in shoulder instability, and should be able to recognize and subsequently treat them to achieve the goal of a stable non-painful shoulder. Unrecognized or not treated lesions may result in recurrence of instability episodes and pain while overuse of some of the techniques previously described can lead to stiffness, thus the importance of an accurate diagnosis and treatment when facing a shoulder instability.

Single anterior portal: A better option for arthroscopic treatment of traumatic anterior shoulder instability?

Objective

The aim of this study was to compare single and double anterior portal techniques in the arthroscopic treatment of traumatic anterior shoulder instability.

Methods

A total of 91 cases who underwent arthroscopic Bankart repair for anterior shoulder instability were reviewed. The patients were divided into 2 groups as Group 1 (47 male and 2 female; mean age: 25.8 ± 6.8) for arthroscopic single anterior portal approach and Group 2 (41 male and 1 female; mean age: 25.4 ± 6.6) for the classical anterior double portal approach. The groups were compared for clinical scores, range of motion, analgesia requirement, complications, duration of surgery, cost and learning curve according to a short questionnaire completed by the relevant healthcare professionals.

Results

No statistically significant difference was found between the 2 groups in terms of pre-operative and post-operative Constant and Rowe Shoulder Scores, range of motion and complications (p > 0.05). In Group 2 patients, the requirement for post-operative analgesics was significantly higher (p < 0.001), whereas the duration of surgery was statistically significantly shorter in Group 1 (p < 0.001). In the assessment of the questionnaire, it was seen that a single portal anterior approach was preferred at a higher ratio (p = 0.035). The cost analysis revealed that the cost was 5.7% less for patients with a single portal.

Conclusion

In the arthroscopic treatment of traumatic anterior shoulder instability accompanied by a Bankart lesion, the anterior single portal technique is as successful in terms of clinical results as the conventional double portal approach. The single portal technique has advantages such as less postoperative pain, a shorter surgical learning curve and lower costs.

Shoulder Stiffness: Current Concepts and Concerns

Shoulder stiffness can be caused by various etiologies such as immobilization, trauma, or surgical interventions. The Upper Extremity Committee of ISAKOS defined the term "frozen shoulder" as idiopathic stiff shoulder, that is, without a known cause. Secondary stiff shoulder is a term that should be used to describe shoulder stiffness with a known cause. The pathophysiology of frozen shoulder is capsular fibrosis and inflammation with chondrogenesis, but the cause is still unknown. Conservative treatment is the primary choice. Pain control by oral medication, intra-articular injections with or without joint distension, and physical therapy are commonly used. In cases with refractory stiffness, manipulation under anesthesia or arthroscopic capsular release may be indicated. Because of various potential risks of complications with manipulations, arthroscopic capsular release is preferred. After the capsular release, stepwise rehabilitation is mandatory to achieve satisfactory outcome.

Anterior shoulder instability: a review of pathoanatomy, diagnosis and treatment

The glenohumeral joint is inherently predisposed to instability by its bony architecture. The incidence of traumatic shoulder instability is 1.7% in the general population. Associated injuries to the capsulolabral structures of the glenohumeral joint have been described and may play a role in predicting recurrent instability. Advanced imaging, computed tomography or MRI may be necessary to adequately evaluate for associated glenohumeral pathology. Treatment algorithms have traditionally included a period of non-operative management in all patients, however young athletic patients may often benefit from early operative treatment. Various open and arthroscopic surgical options exist to address anterior glenohumeral instability. Bony injuries including bony Bankart lesions and Hills Sachs lesion have been implicated in failed surgical management using techniques that address only the soft tissues. An individualized treatment approach, based upon the patient's injury pattern and expectations, will likely lead to the most successful outcome.
