AOA Critical Issues Symposium: Leadership and Education During and After COVID-19: Back to the Future or a New Normal.

ABSTRACT: The devastating impact of COVID-19 has reshaped how we lead and train our future surgeons in the field of orthopaedics. Overnight, leaders in our field had to dramatically shift their mindset to continue to lead a hospital, department, journal, or residency or fellowship program in the face of an unprecedented level of adversity in the history of the United States. This symposium discusses the role of physician leadership during and after a pandemic, as well as the adoption of technology for training surgeons in the field of orthopaedics.

Arthroscopic subacromial decompression.

In this study, we analyzed the results of two series of patients treated for impingement syndrome by undergoing arthroscopic subacromial decompression (ASD). Patients had not responded to nonoperative treatment. Group 1 included 112 consecutive patients (average age, 41 years) with 96 (77%) patients available for 2-year follow-up. Group 2 (28 patients, 29 shoulders; average age, 43 years; range, 22 to 72) had ASD and the subacromial space digitally palpated to determine if adequate decompression was performed. Twenty-two (85%) of 26 shoulders were available for follow-up. At follow-up, pain, function, range of motion, strength, impingement signs, and patient satisfaction were assessed. In group 1, according to the Neer criteria, 48% of the patients were graded as satisfactory and 52% unsatisfactory. Workers' Compensation patients had a satisfactory rate of 32%, whereas non-Workers' Compensation patients had a satisfactory rate of 59%. Twenty patients had open acromioplasty after ASD. Inadequate decompression was noted in 14 of 20 failed patients. In group 2, 86% of the patients were graded as satisfactory according to the Neer criteria, with 14% unsatisfactory, which included the 2 failures. The 2 (9%) of 22 shoulders that failed the ASD went on to further surgical treatment. Average follow-up was 56 months (range, 13 to 78 months). The average American Shoulder and Elbow Society score at follow-up was 90.4. No difference between Workers' Compensation cases and the other cases was seen (P <.7). Finger palpation can help to improve outcomes by allowing the surgeon to assess the adequacy of decompression.

The relationship of the infrapatellar branches of the saphenous nerve to arthroscopy portals and incisions for anterior cruciate ligament surgery. An anatomic study.

The purposes of this study were 1) to carefully define the anatomic distribution of the infrapatellar branches of the saphenous nerve, 2) to provide the surgeon with reliable parameters for where the nerve is most commonly encountered, and 3) to provide specific surgical recommendations to minimize the risk of nerve injury. To accomplish these goals, we dissected 20 cadaveric, fresh-frozen, matched-pair knees. Calipers were used to measure the distance from the nerve to three clinically relevant and easily reproducible landmarks: the inferior pole of the patella, the medial border of the patella at its midpoint, and a point 2 cm medial to the patellar ligament at the level of the joint line. Distances were recorded with the knees in extension and in 90 degrees of flexion to examine the effect of dynamic knee motion on nerve position. We consistently found two main trunks of the nerve that traverse the knee primarily in a medial to lateral but somewhat proximal to distal direction. Because of this, we recommend that incisions for arthroscopy portals be made in a horizontal fashion to decrease the likelihood of nerve injury. Measured from both the inferior pole of the patella and the medial border of the patella, the nerve moved distally with knee flexion. We therefore recommend that incisions across the anterior aspect of the knee be made with the knee in flexion. In 8 of our 20 specimens, the nerve was actually found at the landmark located 2 cm medial to the patellar ligament. This is an extremely high-risk area and should be avoided if possible.

Diagnosis and treatment of congenital thumb hypoplasia.

The hypoplastic thumb has a variety of presentations, which have been generalized into a formal classification system that has treatment implications. In most cases, the spectrum of hypoplasia has predictable deficits in terms of tendon and bone absence. The ultimate goal is always the same--to enhance usage of the radial digit. In this article, a straightforward, reliable, and reproducible surgical technique is discussed and illustrated. Pitfalls, indications, and treatment regimes also are discussed to help the physician successfully treat the child with a hypoplastic thumb.

Reconstruction of the anterior cruciate ligament in patients who are at least forty years old. A long-term follow-up and outcome study.

The long-term results were reviewed for seventy-two patients (seventy-five knees) who had had a bone-patellar ligament-bone intra-articular reconstruction of the anterior cruciate ligament between August 1984 and May 1992. The mean age of the patients at the time of the operation was forty-five years (range, forty to sixty years). Three patients had a bilateral procedure. The primary mechanisms of injury were accidents that occurred during skiing (thirty-two knees), tennis (fourteen knees), and soccer (five knees). We analyzed the responses to subjective questionnaires, the functional results, and the objective clinical data. The clinical examination included assessment of the range of motion, performance of Lachman and pivot-shift tests, and measurements with use of a KT-1000 arthrometer. All knees were evaluated with use of three common rating scales: that of Lysholm and Gillquist; that of The Hospital for Special Surgery, as modified by Insall et al.; and the International Knee Ligament Standard Evaluation Form. At the latest follow-up evaluation, at a mean of fifty-five months (range, twenty-six to 117 months), three patients reported pain or swelling. No patient reported giving-way or symptoms related to the patellofemoral joint. The mean range of extension was -12 to 6 degrees, compared with -8 to 42 degrees preoperatively, and the mean range of flexion was 112 to 150 degrees, compared with 52 to 154 degrees preoperatively. Flexion was limited to 112 degrees in one patient, but this was 5 degrees greater than that of the uninvolved knee. Sixty knees (80 per cent) had a negative pivot-shift test, and ten knees (13 per cent) had a grade of 1+. On testing with the KT-1000 device at maximum manual pressure, the mean difference between the injured and uninjured knees was found to have improved by 5.1 millimeters, from 6.4 millimeters preoperatively to 1.4 millimeters postoperatively (p < 0.01). The grade on the International Knee Ligament Standard Evaluation Form improved markedly; seventy-two knees (96 per cent) had a grade of C or D preoperatively, whereas seventy knees (93 per cent) had a grade of A or B postoperatively. The Hospital for Special Surgery score improved from a mean of 69 points preoperatively to a mean of 92 points postoperatively (p < 0.01). The mean score according to the scale of Lysholm and Gillquist increased from a mean of 63 points preoperatively to a mean of 94 points postoperatively (p < 0.01). All patients indicated that they were pleased with the result of the procedure. Bicycling was resumed at a mean of four months; jogging, at a mean of nine months; skiing, at a mean of ten months; and tennis, at a mean of twelve months.

Femoral neck and ipsilateral neck and shaft fractures in the young adult.

Femoral neck and ipsilateral neck and shaft fractures in the young adult represent a significant source of morbidity and mortality. This article reviews the anatomy, pathophysiology, radiographic evaluation, timing of surgery, and complications in an attempt to increase recognition of these injuries and provide better patient care.

The hypothenar fat pad flap for management of recalcitrant carpal tunnel syndrome.

The hypothenar fat pad flap interposes adipose tissue from the hypothenar eminence between the median nerve and overlying transverse carpal ligament and surgical scar. This retrospective study reviews 62 hands in 58 patients (46 non-workers' compensation and 16 workers' compensation) with recurrent symptoms after failed open carpal tunnel release who underwent revision carpal tunnel decompression and in whom a hypothenar fat pad flap was used. The follow-up period averaged 33 months. Patient satisfaction was 6 in the non-workers' compensation group and 4 in the workers' compensation group. Average time to return to work for the non-workers' compensation group was 12 weeks, compared to 37 weeks for the workers' compensation group. Study results indicate that the hypothenar fat pad flap produces excellent results in procedures designed to alleviate recalcitrant idiopathic carpal tunnel syndrome.

Recalcitrant carpal tunnel. The hypothenar fat pad flap.

Open decompression of the median nerve generally is so effective that little is mentioned of the surgical treatment options for recalcitrant or unrelieved carpal tunnel syndrome. The hypothenar fat pad flap has been shown to be a reliable local source of well-vascularized adipose tissue that can be used for coverage of the median nerve during re-exploration of recurrent or persistent idiopathic carpal tunnel syndrome. The hypothenar fat pad flap is a technically simple procedure that allows the fat pad to be mobilized easily and placed across the palm as a barrier between the nerve and the radial leaf of the transverse carpal ligament, effectively preventing median nerve readherence. This flap hopefully will improve the tissue environment for the median nerve, permitting it to have normal excursion during wrist motion. Our results to date have been better than previously described for other techniques. We believe the hypothenar fat pad flap should be considered in the hand surgeon's armamentarium for recalcitrant idiopathic carpal tunnel syndrome.

Elbow injuries to the throwing athlete.

Elbow injuries in the throwing athlete are common. Because of the tremendous medial tensile forces and lateral compressive forces borne by the elbow, there is a wide array of injuries that occur. A detailed history and physical examination are necessary for an accurate diagnosis. Many of the injuries discussed can be treated successfully with conservative measures followed by aggressive physical therapy. Prompt recognition and early treatment is mandatory. In those conditions in which conservative treatment tends to fail, the detailed surgical options have been discussed. It is important to select highly motivated patients for those procedures that require extensive rehabilitation postoperatively. The keys to success in elbow surgery are a compliant patient and a well-regimented rehabilitation program.

Compressive neuropathies and tendinopathies in the athletic elbow and wrist.

Overuse syndromes of the upper extremity in the athletic population are a common and often difficult problem for physician and patient alike. Optimal function of the upper extremity is tied intimately to success in many sporting activities. Correct diagnosis and proper care require a thorough knowledge of the pertinent anatomy, pathophysiology, and pathomechanics involved in each disorder. Conservative care with rest, activity modification, and medication is adequate for most athletic injuries. Surgical intervention may be indicated for continuing pain, decreased performance, or to prevent chronic changes. Surgery must be followed by thoughtfully prepared training and rehabilitation programs to optimize the chances of a successful outcome.

Arthroscopic removal of loose bodies of the elbow.

Arthroscopy of the elbow has proven to have a diagnostic and therapeutic benefit. Removal of loose bodies and a thorough evaluation of associated intra-articular pathologies are possible without arthrotomy. The authors have found this procedure to be safe and effective in the treatment of loose bodies of the elbow and other associated pathologies.

Percutaneous Kirschner wire fixation through the snuff box: an anatomic study.

We undertook this study to better define the anatomy of the radial aspect of the wrist and to establish a zone of safety for the placement of Kirschner wires, cannulated screws, and arthroscopes within the anatomic snuff box. Twenty fresh frozen cadaver upper extremities underwent placement of three percutaneous Kirschner wires under fluoroscopic guidance through the anatomic snuff box. In each extremity, one Kirschner wire was placed into the radial styloid, one across the scaphocapitate joint, and one across the scapholunate joint. A safe zone of mean 0.68 sq cm was found deep to the subcutaneous tissue bordered by the radial styloid, the first dorsal compartment, the radial artery, and the superficial radial nerve. Kirschner wires placed distal, dorsal, or palmar to the borders of the safe zone were at great risk of injuring neurovascular structures. To minimize the risk of injury to adjacent structures, we advise a limited incision in the safe zone with blunt dissection to the wrist capsule. Though improved anatomic understanding, we established a new location for the arthroscopic 1,2 portal within the snuff box.
