Arthroscopic-Assisted Intraosseous Bioplasty of the Humeral Head for Osteonecrosis.

Osteonecrosis of the humeral head is an uncommon condition, and treatment options are controversial. The shoulder is the second most common location for osteonecrosis, typically presenting between the second and fifth decades of life. Early diagnosis and treatment are essential because osteonecrosis may progress and lead to significant pain and loss of function. Nonoperative options are limited and are based on addressing the cause of the osteonecrosis. Multiple surgical treatments have been described, and these techniques continue to evolve. Open core decompression of the humeral head has been found to be an effective surgical option to restore blood supply and stimulate new bone formation. The evolution of arthroscopic techniques combined with biological adjuncts allows a minimally invasive approach with potential to accelerate revascularization and bone growth. We describe our technique for arthroscopic-assisted intraosseous bioplasty of the humeral head for the treatment of osteonecrosis.

The "BioHumi" Humeral Head Osteochondral Allograft Transplantation for Reverse Hill-Sachs Lesion of the Shoulder.

Osteochondral defects of the shoulder due to posterior instability are less frequent than those caused by anterior instability. Although uncommon, locked posterior dislocations can create sizable osteochondral lesions of the anterior humeral head known as reverse Hill-Sachs lesions. Treatment of these defects to restore the congruent contour of the glenohumeral joint is essential to reduce recurrence of instability and prevent long-term sequelae of arthritis. Historically, nonanatomic options, such as transposition of the subscapularis tendon or lesser tuberosity into the defect and humeral rotational osteotomy, have been endorsed to treat reverse Hill-Sachs lesions. More contemporary techniques have focused on restoring not only the bony architecture but also the chondral surface using fresh osteochondral allografts. The evolution of this approach has been challenging because of the large impacted wedge-shaped defect typically encountered with a locked posterior dislocation. Many surgeons employ techniques using multiple circular grafts or customizing a nonanatomic graft to fill these defects. Given the unstable nature of these grafts, metallic screws are often placed through the chondral surface for fixation. The evolution of the "BioHumi" technique has made treatment of large reverse Hill-Sachs lesions technically simpler and more reproducible using innovative instrumentation to transplant an elliptical osteochondral allograft.

Failure and Complication Rates in Common Sports and Arthroscopic Procedures: Reality Check.

Expectations following sports medicine and arthroscopic procedures have been elevated because of captivating modern-day media coverage of high-profile athletic injuries, surgery, and rapid return to sports. Unfortunately, this general perception may be misleading, and orthopedic sports medicine physicians must be aware of the harsh reality of the trials and tribulations associated with the subspecialty. The purpose of this review article is to provide an updated brief overview of the complications and failure rates associated with common arthroscopic procedures including rotator cuff repair, biceps tenodesis, Bankart procedure, Latarjet procedure, anterior cruciate ligament reconstruction, anterior cruciate ligament repair, meniscal repair, tibial tubercle osteotomy, and medial patellofemoral ligament reconstruction. Highlighting the complications is the first step toward early recognition, enhancing preventative measures, and successful management.

The "BioHumi" Humeral Head Elliptical Osteochondral Allograft Transplantation.

Cartilage defects of the humeral head in young, active patients provide a challenge to treating surgeons. The causes of humeral head osteochondral lesions are variable, but these lesions most commonly result from trauma and recurrent glenohumeral instability. Palliative and reparative techniques such as arthroscopic debridement and microfracture have traditionally been used as surgical treatment but have high failure rates. Similarly to surgical trends in the knee, cartilage restoration in the shoulder is becoming more prevalent in younger patients. Osteochondral allograft transplantation (OAT) has been used as a joint-preserving surgical option to restore hyaline cartilage in multiple joints for decades. Although OAT is more commonly used to re-establish the subchondral bony architecture in the treatment of recurrent shoulder instability, the procedure may also be indicated in young, active patients with focal humeral head chondral defects. OAT has been shown in early studies to provide improvement in functional outcome scores and good long-term graft survival with relatively low rates of complications. This report describes our straightforward, reproducible technique for the treatment of large, oblong chondral defects of the humeral head using OAT.

The Near-Term Ramifications of Long-Term Trends in Orthopedic Surgical Reimbursement.

BACKGROUND: There has been 25-year trend of decreasing value for orthopedic surgical work based on the Resource-Based Relative Value Scale (RBRVS) for Medicare reimbursement. This study was undertaken to estimate the time that Medicare payment rates for time spent in the office doing cognitive work will equal time dedicated in the operating room to performing procedural work based on long-term negative payment trends. METHODS: The RBRVS Update Committee database was accessed to extract the time elements for 2 procedures, total knee arthroplasty and total hip arthroplasty (27447 and 27130), on the day of surgery. The evaluation and management code mix for 2 mid-sized orthopedic practice was averaged to create an amalgamated rate for the reimbursement of office work on an hourly rate. A graph of the 25-year trend line in Medicare reimbursement for arthroplasty procedures was used to create a trend line. The trend line was then extrapolated to estimate the time in the future that the hourly rate for office work would equal the hourly rate for surgery. RESULTS: Time inputs and the Medicare conversion factor for 2021 were used in this analysis. Total procedural time for both 27447 and 27130 was 204 minutes (3.4 hours) on the day of surgery. An amalgamated hourly office rate of 7.9 relative value unit was calculated from the average of the 2 mid-sized private practices for an overall in office Medicare reimbursement of $318.89/h, with $1083.04 for the 3.4 hours allowed in the RBRVS Update Committee database for a joint replacement. When the trend line for reimbursement was extrapolated to the $1083.04 price point, the year corresponding to the point where hourly office reimbursement would equal hourly surgical work was 2024. CONCLUSION: Policymakers in Washington and practicing orthopedic surgeons need to consider the looming economic parity of surgical and cognitive work for Medicare. Continued negative reimbursement rates are likely to decrease patient access to necessary surgical care and result in de facto rationing of arthroplasty services for Medicare patients. The deployment of the orthopedic workforce is likely to change to accommodate the decreases in the value of surgical work. This trend will have significant impact on the practice of musculoskeletal medicine and patient access to orthopedic services.

Lateral Meniscal Allograft Transplant: Dovetail Bone Bridge Preparation.

Meniscal tears are among the most common knee injuries encountered by an orthopaedic surgeon. Once treated with total meniscectomy, meniscal preservation is now the standard of care. Not all meniscal tears are repairable, and meniscal allograft transplantation has become an integral part of the preservation algorithm. This procedure is often recommended in a young active patient with healthy articular cartilage who has undergone a previous subtotal or total meniscectomy. There are many surgical methods for meniscal allograft transplantation, and the bone bridge technique has shown good improvement in outcome scores and good long-term survival. We describe our preferred technique for preparation of the dovetail bone bridge meniscal allograft for lateral meniscal allograft transplantation.

Distal Patellar Tendon SpeedBridge Repair.

Patellar tendon ruptures are rare injuries in young athletes, resulting in disruption of the extensor mechanism, and require surgery for functional recovery. Several techniques have been reported, including end-to-end repair and single-row suture anchor constructs. The strength of these repairs has been questioned, and they are commonly augmented. We endorse a double-row repair technique that provides an anatomic restoration of the footprint, has high fixation strength, eliminates the need for graft augmentation, and allows early motion.

Arthroscopic-Assisted Bone Graft Harvest From the Proximal Humerus for Distal Third Clavicle Fracture Nonunion.

Clavicle fracture nonunion can lead to persistent pain and loss of shoulder function. Distal clavicle fractures have the greatest risk of nonunion and are often treated surgically. Bone grafting plays a vital role in the treatment of distal clavicle nonunion. Although multiple options for bone graft exist, the iliac crest has long been considered the gold standard for harvest. Despite its extensive use, multiple complications have been associated with iliac crest bone graft harvest. We advocate a surgical technique for arthroscopic bone graft harvest from the proximal humerus with open reduction and internal fixation of an ipsilateral distal clavicle nonunion.

Arthroscopic Low-Profile Knotless Repair of SLAP Tears With Suture Tape.

SLAP tears have been a controversial topic in shoulder surgery for decades. The indications for repair of SLAP tears, as well as the methods of repair, have undergone a recent evolution. The use of intra-articular knots for SLAP repair has fallen out of favor because of potential abrasive damage to the rotator cuff and glenohumeral articular cartilage due to knot migration and prominence. In response to this potential iatrogenic injury, arthroscopic techniques have undergone an evolution using advanced techniques with low-profile knotless repairs. We describe our preferred low-profile knotless technique for SLAP repair using LabralTape (Arthrex) in a horizontal mattress configuration.

Physeal-Sparing Transosseous-Equivalent Arthroscopic Rotator Cuff Repair.

Rotator cuff injuries in the skeletally immature population are uncommon, with most tears resulting from trauma or overuse in throwing athletes. Although the literature has referenced multiple repair methods in the pediatric population, an arthroscopic physeal-sparing technique has yet to be described. Given the proximity of the proximal humerus growth plate to the typical anchor placement during rotator cuff repair, we advocate a technique that avoids violation of the proximal humeral physis. Our technique shows an arthroscopic physeal-sparing repair using standard arthroscopic equipment and fluoroscopy.

Distal Triceps Speed Bridge Repair.

Distal triceps ruptures are uncommon injuries resulting in loss of elbow extension strength and necessitating surgical repair to ensure optimal functional outcome. Traditional fixation techniques using running, locking sutures through the tendon secured through bone tunnels have been shown to poorly restore the anatomic footprint and are mechanically inferior to anatomic repairs. We endorse restoring the anatomic footprint of the distal triceps, similar to the well-researched rotator cuff repair model.

Arthroscopic Treatment of Capitellum Osteochondritis Dissecans With Micronized Allogeneic Cartilage Scaffold.

Osteochondritis dissecans (OCD) of the capitellum is a common disorder that causes pain and functional limitation in the adolescent elbow. Although conservative management is the first line of treatment, surgical intervention is usually recommended for patients with persistent mechanical symptoms, loose bodies, or unstable lesions. Elbow arthroscopy has become the gold standard to evaluate and treat symptomatic OCD lesions. Arthroscopic debridement and bone marrow stimulation have been shown to yield good short-term results. Unfortunately, long-term follow-up has shown less favorable outcomes, with degenerative changes frequently documented. Current marrow stimulation techniques promote the formation of fibrocartilage, which is known to be less durable than hyaline cartilage. We describe an arthroscopic technique of debridement and drilling supplemented with a micronized allogeneic cartilage scaffold to address OCD lesions of the capitellum in an effort to promote hyaline cartilage formation.

Arthroscopic Knotless Repair of the Posterior Labrum Using LabralTape.

Operative management of symptomatic labral tears of the shoulder has traditionally been the preferred treatment. Arthroscopic techniques and equipment continue to be refined and subsequent new recommendations for treatment are being developed. Contemporary techniques for arthroscopic knotless repair offer possible advantages over traditional arthroscopically tied knots. Although knotless repair of labral tears is well recognized, advancements continue to progress toward stronger fixation with reduced risks of cutting through the labrum and chondral abrasion. The suture tape used in the technique presented for arthroscopic knotless repair is stronger and flatter than traditional rounded suture and offers many potential benefits.

Excision and Reimplantation of the Proximal Humerus After Fracture-Dislocation.

Fractures of the proximal humerus are common and the treatment for both displaced and comminuted variants remains controversial. Treatment options initially consisted of closed reduction, traction, casting, and abduction splints. In the early 1930s, operative treatment for displaced fractures gained popularity, which continued in the 1940s and 1950s. Humeral head replacement for severely displaced fractures of the proximal humerus was introduced in the 1950s. In the 1970s, the Association for Osteosynthesis/Association for the Study of Internal Fixation popularized plates and screws for fracture fixation, and humeral head prostheses were redesigned. The traditional management of severely displaced proximal humerus fractures has been with arthroplasty because of the significant risk of osteonecrosis of the humeral head following open reduction and internal fixation. The authors present a case of a 51-year-old right-hand-dominant man who sustained a seizure along with a posteriorly displaced proximal humerus fracture-dislocation of the right upper extremity. This was treated with surgical extrusion of the entire humeral head and subsequent open reduction and internal fixation. During the surgical procedure, the patient's humeral head was completely extruded from the body through a posterior incision and then reduced back to the proximal humerus through the standard anterior deltopectoral approach. After 4 years of follow-up, the patient remains pain free, has functional range of motion, and is without signs of osteonecrosis on plain radiographs. This case illustrates that even with complete disruption of the vascular supply to the humeral head, revascularization after osteosynthesis is possible. [Orthopedics. 2016; 39(4):e779-e782.].

Arthroscopic Reverse Remplissage for Posterior Instability.

Posterior shoulder dislocation is an unusual injury often associated with electrical shock or seizure. As with anterior instability, patients frequently present with an impaction injury to the anterior aspect of the humeral head known as a "reverse Hill-Sachs lesion." The treatment of this bony defect is controversial, and multiple surgical procedures to fill the defect in an effort to decrease recurrence have been described. Most of the reports have focused on an open approach using variations of lesser tuberosity and subscapularis transfers, bone allograft, and even arthroplasty to assist with persistent instability. We advocate an arthroscopic technique that involves a suture anchor-based distal tenodesis of the subscapularis tendon or a reverse remplissage procedure.

Arthroscopic Debridement of the Thrower's Shoulder: Less Is More.

The thrower's shoulder has long been a topic of debate among shoulder specialists. The tremendous forces produced during the throwing motion coupled with the compilation of the pathology encountered in the thrower's shoulder have generated a complex treatment algorithm. Simplifying management options has been challenging and recommendations continue to evolve. Treatment of injuries to the thrower's shoulder most commonly involves addressing partial articular-sided rotator cuff tears. These can be isolated or more commonly associated with tearing of the posterior superior labrum. The understanding of the dramatic difference between the surgical treatment of shoulder injuries in overhead athletes and nonoverhead athletes is paramount to positive outcomes after surgery.

Transosseous Medial Meniscal Root Repair Using a Modified Mason-Allen Suture Configuration.

Medial meniscal tears are among the most common injuries to the knee joint. Loss of the meniscus has been linked to increased contact pressures on the adjacent articular cartilage and progression of degenerative changes in the knee. A subset of tears known as "root tears" involves the insertion of the posterior horn of the meniscus to the bone. Arthroscopic partial meniscectomy for root tears led to undesirable outcomes, which prompted surgeons to explore restorative procedures. Multiple repair techniques have been presented with an emphasis placed on initial secure fixation and stimulation of potential healing. We present an arthroscopic-assisted technique for medial meniscal root repair with these goals in mind.

Arthroscopic Transtendinous Modified Double-Row Suture Bridge Repair of a Bony PASTA Lesion.

Surgical and conservative management of partial tears of the rotator cuff has long been a controversial topic for many generations of shoulder surgeons. These tears frequently occur on both the articular and bursal surfaces and within the intrasubstance of the rotator cuff. The term "PASTA lesion" describes the partial articular supraspinatus tendon avulsion-type injury. A less common variant of this injury is the bony PASTA lesion or partial articular bony avulsion of the supraspinatus tendon (PABAST).

ORV Arthroscopic Reduction and Internal Fixation of Tibial Eminence Fractures.

Tibial eminence fractures are an uncommon but well-described avulsion of the anterior cruciate ligament. Treatment principles are based on the amount and pattern of fracture displacement. Management has evolved from closed reduction and immobilization to arthroscopic reduction and internal fixation followed by early rehabilitation. Various fixation methods have evolved, ranging from arthroscopic reduction and percutaneous screw fixation to arthroscopic suture repair. We present a technique for arthroscopic reduction and internal fixation using a cannulated drill bit and high-strength suture. This technique facilitates anatomic reduction with uncomplicated tunnel placement and suture passing in an effort to allow strong fixation and early rehabilitation.

Interference screw versus suture anchor fixation for subpectoral tenodesis of the proximal biceps tendon: a cadaveric study.

PURPOSE: The purpose of this study was to compare the biomechanical properties of 2 fixation methods for subpectoral proximal biceps tenodesis. METHODS: In 9 matched pairs of cadaveric shoulders, an open subpectoral tenodesis was performed 1 cm proximal to the inferior border of the pectoralis major tendon by use of either an 8 x 12-mm Bio-Tenodesis screw (Arthrex, Naples, FL) with No. 2 FiberWire sutures (Arthrex) or a 5.5-mm Bio-Corkscrew double-loaded suture anchor (Arthrex) with No. 2 FiberWire sutures. The specimens were dissected and mounted in a material testing machine. Cyclic loading (20 to 60 N, 100 cycles, 0.5 mm/s, 5-N preload) was performed, followed by an unloaded 30-minute rest, a 5-N preload, and a load-to-failure protocol (1.25 mm/s) with a 100-lb load cell. Ultimate load (in Newtons), stiffness (in Newtons per millimeter), and modes of failure were recorded. Data were analyzed by use of paired t tests and Wilcoxon signed rank tests. RESULTS: Proximal biceps tenodeses with Bio-Tenodesis screws had a significantly higher mean load to failure (169.6 +/- 50.5 N; range, 99.6 to 244.7 N) than those with Bio-Corkscrew suture anchors (68.5 +/- 33.0 N; range, 24.2 to 119.4 N) (P = .002). Bio-Tenodesis screws also had a significantly higher stiffness (34.1 +/- 9.0 N/mm; range, 20.6 to 48.9 N/mm) than Bio-Corkscrews (19.3 +/- 10.5; range, 5.9 to 32.9 N/mm) (P = .038). CONCLUSIONS: In this cadaveric study the Bio-Tenodesis screw showed a statistically significantly higher load to failure and significantly higher stiffness than the Bio-Corkscrew anchor when used for tenodesis of the proximal biceps tendon in a subpectoral location. CLINICAL RELEVANCE: Biomechanical comparison of these 2 fixation techniques provides information on stiffness and load to failure of alternate fixation methods.
