Shoulder Instability & Dislocation Surgeon in the Lehigh Valley

Dr. Michael D. Hendel, MD, PhD evaluates shoulder dislocations, labral tears, and recurrent shoulder instability for patients in Bethlehem and the Lehigh Valley. A first dislocation is often managed with a period of protection and rehabilitation; arthroscopic Bankart (labral) repair, or a Latarjet procedure when there is significant bone loss, is considered for recurrent instability or high-risk athletes.

Shoulder Dislocation & Instability Care in Bethlehem & the Lehigh Valley

The shoulder is the most mobile joint in the body — and the most commonly dislocated. When the ball slips partly (subluxation) or completely (dislocation) out of the socket, it can tear the labrum, stretch the capsule, and in some cases wear away bone. Dr. Michael Hendel, MD, PhD evaluates and treats shoulder dislocations, labral tears, and recurrent shoulder instability for athletes and active adults across Bethlehem, Allentown, Easton, and the greater Lehigh Valley. He completed both his residency and sports medicine fellowship at Hospital for Special Surgery.

Dr. Hendel manages shoulder injuries throughout the year as team physician for the Reading Royals (ECHL professional hockey), the Lehigh Valley IronPigs (Triple-A baseball), PIAA District XI football, and PIAA state wrestling — settings where dislocations and labral injuries are among the most frequent problems he sees. He previously served as an assistant team physician for the New York Giants (NFL).

Conditions Treated

  • First-time and recurrent anterior shoulder dislocation — the ball slipping out the front of the socket, the most common pattern
  • Posterior instability — less common, often seen in football linemen, weightlifters, and after seizures
  • Bankart tears — tears of the front-lower labrum that typically accompany anterior dislocation
  • Bony Bankart lesions and glenoid bone loss — fracture or gradual erosion of the socket rim from repeated dislocations
  • SLAP tears — tears of the upper labrum at the biceps anchor, common in throwing and overhead athletes
  • Multidirectional instability (MDI) — generalized looseness of the shoulder in more than one direction, often without a single traumatic injury

Nonoperative Care Comes First

Many unstable shoulders do not need surgery. After a first dislocation — and in nearly all cases of multidirectional instability — treatment usually begins with a short period of sling immobilization, activity modification, and a structured physical therapy program focused on rotator cuff and scapular (shoulder blade) strengthening. For MDI in particular, a genuine, sustained course of rehabilitation is the primary treatment, and surgery is reserved for patients who remain significantly limited despite it.

Surgery becomes a stronger consideration when dislocations recur, when imaging shows a significant labral tear or bone loss, and in younger athletes in contact or overhead sports — the group with the highest published risk of repeat dislocation. Each additional dislocation can enlarge the injury, so the decision is individualized: Dr. Hendel reviews your examination and imaging with you and explains both paths, including what each realistically involves.

Arthroscopic Bankart Repair

When the labrum is torn and bone loss is minimal, arthroscopic Bankart repair is the most common stabilizing operation. Working through small incisions with a camera, Dr. Hendel reattaches the torn labrum to the rim of the socket using small suture anchors and re-tensions the stretched capsule. This restores the “bumper” that deepens the socket and the checkrein effect of the ligaments. The procedure is typically outpatient, performed at St. Luke’s Orthopedic Hospital — West End Campus in Allentown.

Latarjet Procedure for Bone Loss

Repeated dislocations can wear away the front of the socket (glenoid bone loss) or leave a divot in the back of the ball (a Hill-Sachs lesion). When bone loss passes certain thresholds, a soft-tissue repair alone has a meaningfully higher chance of failing. In these situations Dr. Hendel may recommend the Latarjet procedure, which transfers the coracoid — a small piece of bone from the front of the shoulder blade, with its attached tendon — to the deficient socket rim. The transferred bone restores the socket’s width, and the tendon adds a dynamic sling of support. Latarjet is also commonly used after a failed prior Bankart repair and in selected collision athletes.

The choice between Bankart repair and Latarjet is driven by objective measurements of bone loss on CT or MRI, your dislocation history, and your sport — not by a one-size-fits-all preference.

Return to Sport

Return to play after stabilization surgery is based on milestones, not the calendar alone. Typical criteria include full, pain-free range of motion; strength comparable to the opposite shoulder; no apprehension on examination; and completion of sport-specific training. For most athletes this falls in the range of 5 to 7 months after arthroscopic Bankart repair, with contact and collision sports at the later end; timelines after Latarjet also depend on confirmation of bone healing on imaging. Overhead athletes such as pitchers often require a longer, graduated throwing progression. Your individual timeline may differ based on your injury pattern, procedure, and rehabilitation progress.

A note on recurrent dislocations: if your shoulder has dislocated more than once, an evaluation is worthwhile even if it “goes back in” on its own. Repeat dislocations can progressively damage the labrum and bone, and earlier assessment keeps more treatment options open.

Frequently Asked Questions

Not necessarily. Many first-time dislocations are treated with a short period of immobilization followed by physical therapy. However, the risk of repeat dislocation is highest in young athletes in contact or overhead sports, and repeat dislocations can cause progressive damage to the labrum and bone. The right choice depends on your age, sport, degree of bone loss on imaging, and goals — Dr. Hendel reviews these factors with you and explains both the nonoperative and surgical paths.

A Bankart tear is a tear of the labrum — the ring of cartilage that deepens the shoulder socket — at its front-lower edge, and it is the most common structural injury after an anterior shoulder dislocation. Arthroscopic Bankart repair reattaches the torn labrum to the socket with small suture anchors, restoring the shoulder’s stabilizing bumper.

The Latarjet procedure transfers a small piece of bone (the coracoid) with its attached tendon to the front of the shoulder socket. It is generally recommended when repeated dislocations have worn away part of the socket bone, or when a soft-tissue repair alone would have a high risk of failure — for example, after a failed prior Bankart repair or in certain collision athletes with bone loss. Imaging measurements of glenoid and humeral bone loss guide this decision.

Typical recovery involves a sling for about 4 to 6 weeks, progressive motion and strengthening in physical therapy over the following months, and return to contact or overhead sports commonly between 5 and 7 months — once motion, strength, and sport-specific testing support a safe return. Individual timelines vary with the injury pattern, the repair performed, and your sport.

Multidirectional instability (MDI) means the shoulder is loose in more than one direction, often related to naturally loose ligaments rather than a single traumatic injury. Unlike traumatic dislocations, MDI is treated first and foremost with a structured physical therapy program focused on rotator cuff and scapular strengthening. Surgery is reserved for patients who remain significantly symptomatic after a genuine, sustained course of rehabilitation.

A SLAP tear (superior labrum anterior to posterior) is a tear of the upper part of the labrum where the biceps tendon anchors. It is common in throwing and overhead athletes. Many SLAP tears improve with therapy; when surgery is needed, options include labral repair or biceps tenodesis depending on age, sport, and tear pattern.
