RESUMO
STUDY DESIGN: Prospective cross-sectional survey. OBJECTIVE: To identify timelines for when athletes may be considered safe to return to varying athletic activities after sustaining cervical spine fractures. BACKGROUND: While acute management and detection of cervical spine fractures have been areas of comprehensive investigation, insight into timelines for when athletes may return to different athletic activities after sustaining such fractures is limited. METHODS: A web-based survey was administered to members of the Association for Collaborative Spine Research that consisted of surgeon demographic information and questions asking when athletes (recreational vs elite) with one of 8 cervical fractures would be allowed to return to play noncontact, contact, and collision sports treated nonoperatively or operatively. The third part queried whether the decision to return to sports was influenced by the type of fixation or the presence of radiculopathy. RESULTS: Thirty-three responses were included for analysis. For all 8 cervical spine fractures treated nonoperatively and operatively, significantly longer times to return to sports for athletes playing contact or collision sports compared with recreational and elite athletes playing noncontact sports, respectively (P< 0.05), were felt to be more appropriate. Comparing collision sports with contact sports for recreational and elite athletes, similar times for return to sports for nearly all fractures treated nonoperatively or operatively were noted. In the setting of associated radiculopathy, the most common responses for safe return to play were "when only motor deficits resolve completely" and "when both motor and sensory deficits resolve completely." CONCLUSIONS: In this survey of spine surgeons from the Association for Collaborative Spine Research, reasonable timeframes for return to play for athletes with 8 different cervical spine fractures treated nonoperatively or operatively varied based on fracture subtype and level of sporting physicality.
RESUMO
PURPOSE OF REVIEW: As the incidence of shoulder arthroplasty continues to increase, there is growing interest in patient-based factors that may predict outcomes. Based on existing literature demonstrating gender-based disparities following total hip and knee arthroplasty, gender may also influence shoulder arthroplasty. The purpose of this review is to discuss the recent literature on the influence of gender on shoulder arthroplasty, focusing on differences in preoperative parameters, perioperative complications, and postoperative outcomes. RECENT FINDINGS: While both female and male patients generally benefit from shoulder arthroplasty, several differences may exist in preoperative factors, acute perioperative complications, and postoperative outcomes. Preoperatively, female patients undergo shoulder arthroplasty at an older age compared to their male counterparts. They may also have greater levels of preoperative disability and different preoperative expectations. Perioperatively, female patients may be at increased risk of extended length of stay, postoperative thromboembolic events, and blood transfusion. Postoperatively, female patients may achieve lower postoperative functional scores and decreased range of motion compared to male patients. Differences in postoperative functional scores may be influenced by gender-based differences in activities of daily living. Finally, female patients may be at greater risk for periprosthetic fracture and aseptic loosening while male patients appear to be at greater risk for periprosthetic infection and revision surgery. Current literature on the influence of gender on shoulder arthroplasty is limited and conflicting. Further research is necessary to delineate how gender affects patients at the pre- and postoperative levels to better inform decision-making and outcomes.
RESUMO
CASE: A 15-year-old adolescent boy sustained both talar and navicular extrusions after a dirt-bike accident. The talus and navicular were discarded during initial debridement because of contamination. Given extensive soft-tissue injury and bone loss, the patient's family opted for transtibial amputation, as described by Ertl, over limb salvage. Simultaneous osteomyoplastic reconstruction and acute targeted muscle reinnervation were performed. CONCLUSION: Transtibial amputation is a viable treatment option for total talar and navicular extrusions, particularly if an optimal functional outcome is unachievable with limb salvage. Simultaneous osteomyoplastic reconstruction and acute targeted muscle reinnervation can potentially decrease neuroma formation and phantom limb pain.

Purpose: To compare hamstring autograft primary anterior cruciate ligament reconstruction (ACLR) techniques including adult-type/anatomic, transphyseal, and transphyseal techniques by (1) ACL graft tear, (2) contralateral ACL tear, and (3) all-cause ipsilateral reoperation. Methods: A retrospective, single-surgeon review was performed including all ACLR with hamstring autograft in pediatric and adolescent patients from 2011 to 2019. Minimum 2-year follow-up was required for patients unless a tear or reoperation was sustained before that time point. Data collected included demographics and baseline surgical variables, type of reconstruction, sporting activity, and deviations from rehabilitation protocols. Comparisons were made among hamstring autograft reconstruction groups (adult-type/anatomic, transphyseal, and partial transphyseal) for primary outcomes of graft tear, contralateral ACL tears, and all-cause ipsilateral knee reoperations, including hardware removal. Secondary surgeries performed with different surgeons were noted. Results: In total, 214 patients of age 15.2 ± 2.0 years with 4.1 ± 1.7-year follow-up were included. Overall graft tear rate was 11.7% (11.0% adult-type vs 19.1% transphyseal vs 5.6% partial transphyseal; P = .18). On univariate analyses, all-cause ipsilateral reoperation did not differ by technique (21.3% vs 31.0% vs 33.3%; P = .20), and neither did contralateral ACL tear (8.1% vs 9.5% vs 0%; P = .17). 21.7% of ipsilateral revision ACLRs (all adult-type) and 16.7% of patients with any reoperations had subsequent procedures performed with a different surgeon. Conclusions: The graft tear rates in primary hamstring autograft ACLRs in the adolescent population did not significantly differ by technique (11.0% vs 19.1% vs 5.6% in adult-type, transphyseal, and partial transphyseal reconstructions, respectively). Furthermore, contralateral ACL tears (8.1% vs 9.5% vs 0%) and all-cause (including > 1/4 hardware removal) ipsilateral knee reoperations (21.3% vs 31.0% vs 33.3%) did not statistically differ. Higher powered studies may detect statistical significance in the observed differences in this study. Level of evidence: Level IV, therapeutic case series.
RESUMO
BACKGROUND: Proximal junctional failure (PJF) following multilevel thoracolumbar instrumented to the pelvis for adult spinal deformity (ASD) is relatively uncommon but considerably disabling. While the leading etiology is mechanical, other rarer etiologies can play a role in its development. The purpose of this study was to present a case series of ASD patients who experienced PJF secondary to proximal junctional spondylodiscitis (PJS) after long-segment thoracolumbar posterior instrumented fusions. METHODS: Adult patients who underwent posterior instrumented fusions at a single academic center between 2017 and 2020 and subsequently developed PJS were retrospectively reviewed. Patient demographics, operative details, clinical presentation, culture data, and management approach were evaluated. RESULTS: Three patients developed PJS and were included for analysis (mean age 67 years [range, 58-76]; women: 2). Indication for all index operations was symptomatic ASD after failed conservative management. Clinical presentation ranged from mild back pain to severe neurological compromise. Average time to infection and PJF after the index procedure was 11 months (range, 3 months-2 years). All 3 patients were successfully managed with urgent revision surgery including surgical debridement and postoperative antibiotics. CONCLUSION: PJS is a rare yet potentially devastating complication following long-segment posterior thoracolumbar instrumented fusions for ASD. It is critical that surgeons maintain a high index of suspicion of infection when managing PJF given the potential neurological morbidity of PJS. CLINICAL RELEVANCE: This report highlights a rare but important cause of PJF following ASD surgery. It is critical that one maintains a high index of suspicion of infection when managing PJF.
RESUMO
PURPOSE OF REVIEW: Massive irreparable rotator cuff tears present a significant challenge to the orthopedic surgeon. No single treatment, particularly among joint-preserving options, has been shown to be superior. The purpose of this review is to discuss recent advances in the treatment of massive irreparable rotator cuff tears, including partial repair with and without graft augmentation, interposition grafts, superior capsule reconstruction, subacromial balloon spacers, tendon transfer, and reverse total shoulder arthroplasty. We will also offer guidance on surgical indications based on our clinical experience. RECENT FINDINGS: Partial repair may offer reasonable clinical improvement for patients with lower preoperative function despite high re-tear rates. Additionally, several types of interposition grafts have shown promising short-term results and may outperform repair alone. Subacromial balloon spacers may lead to clinical improvement, especially in patients without glenohumeral osteoarthritis or pseudoparalysis, and recently received FDA approval for use in the USA. Superior capsule reconstruction is a technically demanding procedure that appears to produce excellent short-term results particularly when performed at high volume, but long-term studies in heterogeneous study groups are needed. Tendon transfers improve function by restoring force coupling in the shoulder, offering a promising option for younger patients. Reverse total shoulder arthroplasty (RTSA) is a reliable option for treatment of irreparable cuff tears in elderly patients with lower functional demands. Irreparable cuff tears remain a difficult condition to treat. Recommended treatment for younger patients without glenohumeral osteoarthritis is particularly controversial. For older patients with low-demand lifestyles and glenohumeral osteoarthritis, RTSA is an effective treatment option. For all discussed procedures, patient selection appears to play a critical role in clinical outcomes.
RESUMO
PURPOSE: To report a rare ureteral injury following anterior spinal fusion for adolescent idiopathic scoliosis (AIS) that resulted in complete nephrectomy and to delineate the anatomical relationship between the proximal ureter and the anterior lumbar spine based on CT angiography (CTA). METHODS: Thoracolumbar spine CTAs of children with AIS were reviewed. We measured the following relationships to the ureters: lateral-most aspect of vertebral body, anterior psoas at intervertebral disc/vertebral body levels, and lateral psoas at vertebral body level. Spine level at which the renal arteries originated from the aorta was identified. Distance from origin to corresponding vertebral body/intervertebral disc also was measured. RESULTS: Forty-one girls and seven boys (mean age 12 years, range 7-18) were analyzed. Scoliosis lumbar convexity was left 94% and right 6%. From L1 to L4, ureter was identified within 1-2 cm of vertebral body. Distance between ureter and vertebral body and ureter and anterior psoas at intervertebral disc/vertebral body levels was less on left vs. right from L1 to L4 (p < 0.0001). Distance between ureter and lateral psoas was less on left vs. right from L1 to L2 (p = 0.0205; p = 0.0132) and greater on left vs. right from L3 to L4 (p = 0.0022; p = 0.0076). Renal artery originated at L1/L2 in > 50%. There was no difference in distance from renal artery origin to vertebral body/intervertebral disc (p = 0.4764). CONCLUSION: Ureteral injury is a potentially morbid complication of anterior spine surgery. Injury can occur secondary to disrupted blood supply and mechanical tissue damage. Surgeons must clearly understand the juxta-spinal anatomy to limit dissection and modify retraction to reduce risk. LEVEL OF EVIDENCE: Level IV.

Arthroscopic surgery of the shoulder joint and the subacromial space requires adequate visualization to be effectively performed. Visual clarity is essential to perform a safe and successful arthroscopic procedure. The major determinants to provide visualization in the subacromial space and the glenohumeral joint include adequate inflow (dependent on the dimension of the inflow cannula), flow rate versus pressure, pump system versus gravity, the use of electrocautery and radiofrequency devices, blood pressure control and hypotensive anesthesia, and the type of irrigation solution used with or without the use of epinephrine. In 2012, the cost of a 30-mL (30-mg) vial of epinephrine was $6 (adrenalin/epinephrine injection, USP, Par Pharmaceuticals), and approximately 3 to 4 bottles would be used on average for a single shoulder arthroscopy. In 2019, the same 30-mL bottle of epinephrine cost $237, a nearly 40-fold increase. The purpose of our study is to describe the various factors and techniques that can be used to maintain visual clarity in shoulder arthroscopy without the use of epinephrine in the irrigation solution and the cost savings associated without the use of epinephrine.
RESUMO
BACKGROUND: Recurrent shoulder instability results from overuse injuries that are often associated with athletic activity. Timely diagnosis and treatment are necessary to prevent further dislocations and secondary joint damage. In pediatric and adolescent patients, insurance status is a potential barrier to accessing timely care that has not yet been explored. PURPOSE: To examine the effect of insurance status on access to clinical consultation, surgical intervention, and surgical outcome of pediatric and adolescent patients with recurrent shoulder instability. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We conducted a retrospective review of pediatric and adolescent patients who were treated at a single tertiary children's hospital for recurrent shoulder instability between 2011 and 2017. Patients were sorted into private and public insurance cohorts. Dates of injury, consultation, and surgery were recorded. Number of previous dislocations, magnetic resonance imaging (MRI) results, surgical findings, and postoperative complications were also noted. Delays in care were compared between the cohorts. The presence of isolated anterior versus complex labral pathology as well as bony involvement at the time of surgery was recorded. The incidences of labral pathology and secondary bony injury were then compared between the 2 cohorts. Postoperative notes were reviewed to compare rates of repeat dislocation and repeat surgery. RESULTS: A total of 37 patients had public insurance, while 18 patients had private insurance. Privately insured patients were evaluated nearly 5 times faster than were publicly insured patients (P < .001), and they obtained MRI scans over 4 times faster than did publicly insured patients (P < .001). Publicly insured patients were twice as likely to have secondary bony injuries (P = .016). Postoperatively, a significantly greater number (24.3%) of publicly insured patients experienced redislocation versus the complete absence of redislocation in the privately insured patients (P = .022). CONCLUSION: Public insurance status affected access to care and was correlated with the development of secondary bony injury and a higher rate of postoperative dislocations. Clinicians should practice with increased awareness of how public insurance status can significantly affect patient outcomes by delaying access to care-particularly if delays lead to increased patient morbidity and health care costs.
RESUMO
The surgical treatment of ochronotic arthropathy remains unclear. Although there is no absolute cure for ochronotic arthropathy, current management typically begins with conservative treatment. Total joint replacement may eventually be necessary for joints that become severely degenerative. Ochronotic arthropathy is present in patients with alkaptonuric ochronosis, which is characterized by dark pigmentation of connective tissue and black discoloration of urine owing to a deficiency of homogentisic acid oxidase. As a result, soft tissues become brittle and subsequently more susceptible to mechanical stress, resulting in articular cartilage degeneration. The diagnosis of ochronotic arthropathy of the knee often occurs intraoperatively after discovery of darkened synovium and black deposits during arthroscopy. The purpose of this article is to describe arthroscopic debridement as an effective treatment option and diagnostic tool for ochronotic arthropathy of the knee after failure of conservative measures.
RESUMO
Elbow arthroscopy is an increasingly common procedure performed in orthopaedic surgery. However, because of the presence of several major neurovascular structures in close proximity to the operative portals, it can have potentially devastating complications. The largest series of elbow arthroscopies to date described a 2.5% rate of postoperative neurological injury. All of these injuries were transient nerve injuries resolved without intervention. A recent report of major nerve injuries after elbow arthroscopy demonstrated that these injuries are likely under-reported in literature. Because of the surrounding neurovascular structures, familiarity with normal elbow anatomy and portals will decrease the risk of damaging important structures. The purpose of this Technical Note is to review important steps in performing elbow arthroscopy with an emphasis on avoiding neurovascular injury. With a sound understanding of the important bony anatomic landmarks, sensory nerves, and neurovascular structures, elbow arthroscopy can provide both diagnostic and therapeutic intervention with little morbidity.
