ABSTRACT

Deep infection is a debilitating complication after shoulder arthroplasty. The authors hypothesized that an intra-articular, intraoperative injection of antibiotics would result in a lower infection rate compared with intravenous antibiotics alone. Before 2007, 164 patients (group A) did not receive intra-articular antibiotics. From 2007 to 2018, 1324 patients (group B) received intra-articular antibiotics. Patients received intra-articular gentamicin at the end of surgery with the addition of 1 g of cefazolin in January 2014. Records were retrospectively reviewed for comorbidities, type of surgery, and infection. The cohort that received intra-articular antibiotics was compared with the cohort that did not to determine the effect of prophylactic intra-articular antibiotic administration in preventing infection. There was 1 deep infection in the antibiotic group compared with 5 in the non-antibiotic group (P<.001). Superficial infections developed in 2 cases of patients treated with antibiotics; there were no superficial infections in patients treated without antibiotics (P=.62). One previous study evaluated intra-articular injection of antibiotics for shoulder arthroplasty and found significantly lower rates of infection with the injection of intra-articular gentamicin. In this retrospective follow-up study, the injection of intra-articular gentamicin or gentamicin and cefazolin effectively decreased rates of postoperative infection. At mean follow-up of 399 days, intra-articular antibiotics at the time of surgery resulted in significantly fewer deep infections. Given the minimal risk of adverse events and minimal cost, this is a valid method of reducing infections in total shoulder arthroplasty. [Orthopedics. 2023;46(5):310-314.].

ABSTRACT

Shoulder injury related to vaccine administration (SIRVA) is a rare yet increasingly recognized complication of immunization. Although a medicolegal term rather than a true diagnosis, SIRVA was introduced in 2010 by the Vaccine Injury Compensation Program after an increase in claims filed for vaccine-related shoulder injury. Patients typically present with severe pain and limited range of motion within 48 hours of vaccination and may experience notable functional limitations. Although the underlying pathophysiology is incompletely understood, the existing literature suggests that SIRVA results from the inflammatory response produced when the vaccine is injected into tissues containing a preexisting antibody. Current treatment modalities include physical therapy, corticosteroid injections, and antiinflammatory medications. In some cases, surgery may be required to treat underlying pathology, such as rotator cuff or biceps tendinopathy. Although the available literature indicates modest improvement in patients with SIRVA undergoing treatment, current data are limited to case series. Larger, high-quality studies are needed to determine the natural history and optimal treatment of this increasingly prevalent condition.

ABSTRACT

HYPOTHESIS AND BACKGROUND: Complex glenoid bone loss and deformity present a challenge for the shoulder arthroplasty surgeon. Eccentric reaming, bone grafting, augmented glenoid components, and salvage hemiarthroplasty are common strategies for managing these patients. The glenoid vault reconstruction system (VRS; Zimmer-Biomet) is a novel solution for both primary and revision arthroplasty using a custom glenoid baseplate. We hypothesized that patients undergoing reverse shoulder arthroplasty (RSA) with VRS would have acceptable short-term outcomes and complication rates. METHODS: Patients who underwent RSA with VRS for severe glenoid deformity or bone loss by one of 4 board-certified, fellowship-trained shoulder and elbow surgeons at 3 academic tertiary referral centers between September 2015 and November 2018 were eligible for inclusion. Patient data were obtained via medical record review and telephone questionnaires. The Numeric Pain Rating Scale (NPRS), Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Penn Shoulder Scores, and range of motion (ROM) measurements were obtained pre- and postoperatively. Radiographs were reviewed at final follow-up for evidence of component loosening or hardware failure. Any complication was documented. Outcomes were compared using Wilcoxon signed-rank tests with P <. 05 considered significant. RESULTS: Twelve shoulders (11 patients) were included with a mean age of 68 years; 7 were primary arthroplasties and 5 were revisions. At an average follow-up time of 30 months, median improvement in NPRS score was 7 points, SANE score 43%, ASES score 45 points, and Penn Shoulder Score 49 points. There were statistically significant improvements in median ROM measurements (forward elevation 20°, external rotation 40°, internal rotation 2 spinal levels). At final follow-up, all implants were radiographically stable without loosening. There were no complications. DISCUSSION AND CONCLUSION: This study demonstrates that RSA using the custom VRS glenoid implant is a safe and effective technique addressing complex glenoid deformity or bone loss in both primary and revision settings. At short-term follow-up, all patient-reported outcomes and ROM measures improved significantly, and there were no complications. Future work should determine mid- and long-term outcomes, preferably in a prospective manner with defined patient populations.

ABSTRACT

OBJECTIVES: To determine how often preoperative testing is requested for geriatric hip fracture patients, to assess the extent to which preoperative testing is associated with delayed surgery, and to measure the frequency with which preoperative testing changes patient management. DESIGN: Retrospective. SETTING: Academic health system. PATIENTS: Two hundred fifty consecutive geriatric hip fracture patients admitted through the emergency department and underwent surgery. INTERVENTION: Hip fracture surgery. MAIN OUTCOME MEASUREMENTS: The patients were categorized according to whether additional preoperative tests were requested. For each patient, the times of presentation and surgery were recorded, yielding a "time-to-surgery interval." The results of any tests, the actions resulting from testing, and the length of hospital stay were also noted. RESULTS: Additional preoperative testing was performed for 67 patients (27%). For those patients, the mean time-to-surgery was 73 hours. For the 183 patients who had no testing, the mean time-to-surgery was 37 hours. Moreover, 42 of the 67 patients with testing (63%) had time-to-surgery greater than 48 hours, compared with only 37 of the 183 (20%) patients without testing. The mean length of stay for tested patients was 12.0 days compared with 9.0 days for nontested patients. In only 2 of the 67 tested patients was further care offered based on the test result. CONCLUSIONS: Testing was associated with greater time-to-surgery and length of stay. Furthermore, testing rarely influenced management. Patients might be able to have surgery more expeditiously and leave the hospital earlier if testing were deferred. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

When performing revision shoulder surgery, it is important that the surgeon understands why the index procedure failed and has a clear plan to address problems in the revision procedure. The most common cause of failure after anterior instability shoulder surgery is a failure to treat the underlying glenoid bone loss. For most defects, a Latarjet transfer can effectively restore anterior glenoid bone stock and restore shoulder stability. Persistent anterior shoulder pain after rotator cuff surgery may be the result of missed biceps pathology. This can be effectively treated via a biceps tenodesis. The most difficult failures to treat after acromioclavicular joint reconstruction surgery are those involving fractures of either the coracoid or the clavicle. Clavicle hook plates can be used as supplemental fixation during the treatment of these fractures to help offload the fracture site and allow healing while restoring stability to the acromioclavicular articulation. A failed hemiarthroplasty for a proximal humeral fracture frequently results when the tuberosities fail to heal correctly. This complication can be avoided by paying close attention to the implant position and the tuberosity fixation. If hemiarthroplasty is unsuccessful, the patient is best treated with conversion to a reverse shoulder arthroplasty.

ABSTRACT

Although most proximal humerus fractures can be treated nonoperatively, 4-part fractures and 3-part fractures/dislocations in elderly patients often require management with prosthetic arthroplasty. Reverse arthroplasty is gaining in popularity, but hemiarthroplasty still has a role in the management of 4-part and some 3-part fractures and dislocations. The 2 most important technical factors influencing functional outcome in hemiarthroplasty patients are the restoration of the patient's correct humeral head height and version, and healing of the greater and lesser tuberosities in an anatomic position. Hemiarthroplasty for proximal humerus fracture provides predictable pain relief, but functional recovery is much less predictable.

ABSTRACT

In the study reported here, we sought to determine the interobserver reliability and the intraobserver reproductibility of the Mason classification. We also evaluated the effect of having an external rotation oblique view on agreement in radiographic readings. Four readers reviewed 50 radial head fracture radiographs approximately 2 months apart. Half the radiographs had an anteroposterior view and a lateral view; the other half had an additional external rotation oblique view. There was a trend toward improved interobserver agreement in the 3-view radiographs. Three of the 4 readers demonstrated substantial intraobserver reproducibility, which was noted to be higher when 3 views were available.

ABSTRACT

BACKGROUND: The optimal treatment of osteochondritis dissecans (OCD) of the capitellum in adolescent athletes remains challenging. The purpose of this study was to investigate the mid-term results of arthroscopic treatment of OCD of the capitellum in a series of adolescents. METHODS: We identified 25 consecutive patients at our institution that underwent arthroscopic treatment for OCD of the capitellum since 1999. Ten elbows were treated by arthroscopic debridement and drilling alone, whereas 12 elbows required additional mini-arthrotomies for bone grafting or the removal of large loose bodies after arthroscopy. The clinical charts and operative reports of these patients were retrospectively reviewed for relevant clinical information including age, sport, character of symptoms, preoperative and postoperative range of motion, return to sport, and postoperative complications. Twenty-one patients (22 elbows) were reached to determine their current elbow function and athletic activity using the Single Assessment Numerical Evaluation score. RESULTS: The average age of the patients in our series was 13.1 years. All patients participated in organized athletics that involved the upper extremity and had undergone an average of 10.2 months of nonoperative treatment before surgery. At a mean follow-up of 48 months, the patients gained an average of 17 degrees of extension and 10 degrees of flexion after surgery. Both the improvement in flexion and extension were statistically significant compared with the preoperative range of motions (P=0.001, P=0.01). When patients were asked to rate their elbow function from 0% to 100% using the Single Assessment Numerical Evaluation score, the average rating was 87%. Eighteen of 21 patients (86%) returned to participate in their sport at their preinjury level. CONCLUSION: Arthroscopic management of capitellar OCD in adolescent athletes results in significantly improved range of motion and a high rate of return to athletics. Accompanying arthrotomy may be required for large loose body removal or bone grafting.

ABSTRACT

Although literature supports bracing of most medial collateral ligament (MCL) injuries followed by arthroscopic repair of anterior cruciate ligament (ACL) tears in adults with combined ACL-MCL injuries, little is published regarding the treatment of these injuries in the pediatric population. The purpose of this study was to present our outcomes after treatment of combined ACL-MCL injuries in a series of adolescents. All 180 patients who underwent ACL reconstruction at our children's hospital from January 1997 to January 2003 were reviewed to identify those patients with concomitant grade II or III MCL injuries. Clinical data were obtained from chart review. All patients were treated with a hinged brace for their MCL injury followed by delayed arthroscopic reconstruction of their ACL using a transphyseal technique with Achilles tendon soft tissue allograft. Patients were contacted by phone to complete Lysholm knee questionnaires and assess return to athletic competition. Data were compared with a control cohort of patients who underwent isolated ACL reconstruction using the same technique. Twelve (6.7%) of 180 patients had combined ACL-MCL injuries. There were 6 boys and 6 girls; the mean age was 15.6 years (range, 14-17 years). Follow-up averaged 5.3 years (range, 2.6-8.2 years), and no patients were lost to follow-up. At last examination, all patients had a stable knee on both Lachman and valgus stress tests; the mean Lysholm knee score was 96 (range, 94-100). All patients were able to return to their preinjury level of athletics. One patient required manipulation for arthrofibrosis. When compared with the control group of 19 isolated ACL reconstructions, there was no significant difference with regards to Lysholm scores or return to athletics. Bracing of grade 2 or 3 MCL injuries followed by ACL reconstruction was an effective means of treating combined ACL-MCL injuries in this small series of adolescent patients.
