Background: Batter’s shoulder is a condition in which the posterior labrum is typically torn during the baseball swinging motion, producing a traumatic tear and posterior instability. The injury commonly occurs in the batter’s lead shoulder due to repetitive microtrauma, raising concern for switch-hitters due to the cumulative stress of throwing and swinging on the lead shoulder. Instability is commonly caused by a posterior humeral force and relative shoulder adduction, which is most prevalent during a swing attempt at a low and outside pitch. Indications: Damage to the labrum during the acute traumatic event can cause residual pain and recurrent instability of the shoulder. Indications include failed conservative management. The patient demonstrated a full-thickness longitudinal tear that was grossly unstable with gentle probing. Technique Description: After establishing presence of an unstable posterior labral tear during diagnostic arthroscopy, a 7-o’clock portal is established for the labral repair. A knotless suture anchor construct was utilized for its low-profile features. Care is taken to avoid both tangling of sutures and overtensioning of the repair. Results: Patients return to live batting practice at 6 months postoperatively and most patients return to the same level of play following surgical management. Discussion/Conclusion: Avoid overtightening of labral repair and subsequent loss of range of motion. Use of a low-profile knotless suture anchor is the senior author’s preferred method of surgical management. A majority of patients surgically managed for unstable posterior labral injuries return to the same level of play.

Introduction Repairs of labral tears are performed for unstable tears, hip instability, and after detachment concomitant to the treatment of femoroacetabular impingement (FAI), but limited data is known about the strength of repair. This study evaluated the effect of simulated axial weight-bearing on suture anchor based repair of the acetabular labrum. Methods 3 cadaveric pelvises underwent creation of a 1.5 cm anterior-superior labral tear in each hip. The tears were then repaired using 2 suture anchors per hip. Following repair, the hip joint underwent axial cyclic loading to 756 N, and were inspected for separation of the labrum from the acetabulum. The strength of the suture anchor repair was evaluated by testing load to failure, in-line with insertion. Results Upon visual examination, all 6 repairs remained fully intact following loading with no visible gap formation or damage at the repair site. In all cases an arthroscopic probe could not be inserted under the edge of the repair. The mean failure force of the 12 suture anchors, in-line with insertion, was 154 N ± 44 N. Conclusions Acetabular labral suture anchor repairs may be able to immediately withstand the physiological loads of axial weight-bearing. Labral repair may be able to tolerate axial weight-bearing immediately after repair, preserving the strength and integrity of muscles and soft tissues.

ABSTRACT The safe acetabular rim angle is an anatomical measurement used to determine the safety margin when inserting suture anchors. The purpose of the present study was to find out whether aligning the drill bit perpendicularly during arthroscopic surgery can provide a reference point for determining an appropriate angle to facilitate the suture anchor insertion and to prevent extra- and intra-articular perforations. One hundred computed tomographic hips were used to reconstruct three-dimensional acetabular hip models. Each model was radially sectioned at the 4 o’clock, 3 o’clock and anterior inferior iliac spine (AIIS) positions (that corresponded mainly to the 2:20 clock position). A perpendicular reference line, representing a perpendicular drill bit alignment, was drawn for each position within the acetabular model, and its relation to the safe acetabular rim angle was measured. The length of the perpendicular reference line and the effect of gender on measurements were also evaluated. The mean safe acetabular rim angle at the 3 o’clock position was significantly smaller compared to other clock positions (P < 0.001). The perpendicular reference line was located out of the safe acetabular rim angle in 28 cases (%28), mostly in female acetabula at the 3 o’clock position, and relative to the perpendicular reference line the required minimal angle was 4° ± 2.3° to place the anchor in the safe acetabular rim angle to avoid extra-articular perforation. The perpendicular reference line was shortest at the 3 o’clock position, and its mean length was shorter in female acetabula at all clock positions (P < 0.001). Aligning the drill bit perpendicular to the acetabular opening plane during an arthroscopic anchor placement is a practical way to estimate and target the position of the safe acetabular rim angle to avoid anchor perforations. Based on measurements from a perpendicularly aligned drill bit, the drill bit should be directed towards the joint minimally by 4° to avoid extra-articular perforations and maximally by 30° to avoid intra-articular perforations.
