Current Concept and Management of Spastic Hip in Children: A Narrative Review.

Cerebral palsy (CP) is a non-progressive motor condition that hinders the development of movement and posture. One of the common problems faced in CP is spastic hips, which can cause discomfort, deformity, and functional restrictions. This review article seeks to offer a thorough summary of the most recent methods for treating spastic hips in cerebral palsy patients. Additionally, it describes the success and potential risks of various conservative and surgical procedures. It also looks at new treatments and potential avenues for managing this complicated ailment.

Supracondylar Humerus Fractures in Older Children: Success of Closed Reduction and Percutaneous Pinning.

BACKGROUND: The incidence of supracondylar humerus (SCH) fracture declines and fracture types change as children grow. Optimal treatment method is unclear in older children. The aim of the study was to determine if fracture type and configuration of distal humerus fractures changes as patients approach skeletal maturity, and to assess the success of closed reduction and percutaneous pin (CRPP) in extra-articular SCH fractures in this transitional age group. METHODS: Inclusion criteria for this retrospective review were (1) distal humerus fractures with extension types 2 and 3, flexion type, T-type; (2) surgically managed, and (3) modified Sauvegrain score ≥1. Reviewed parameters included fracture type and configuration, grade of skeletal maturity, fixation technique, and loss of reduction. Primary analysis was to determine the distribution of fracture type and configuration with age or grade of skeletal maturity. Secondary analysis was used to determine the factors affecting treatment success of CRPP in extra-articular fractures. RESULTS: A total of 142 patients were included (58 males and 84 females). Fracture types revealed significant changes with increased age (P=0.031) and skeletal maturity grade (P<0.005). Skeletal maturity was a better predictor of changing fracture type than chronological age. T-type fractures were only seen in patients with modified Sauvegrain score ≥6 and flexion-type fractures were only seen in patients with modified Sauvegrain score ≤4. Loss of reduction rate after CRPP was 5%. The success of CRPP was not affected by age, sex, modified Sauvegrain score, fracture type, direction of displacement, coronal fracture pattern, number of pins or medial pin use. Fracture obliquity in the sagittal plane (P=0.05), suboptimal pin spread (P<0.01), and lack of bicolumnar fixation (P<0.01) were found as statistically significant factors associated with failed CRPP. CONCLUSION: The distribution of fracture type changed with increased age and skeletal maturity. CRPP of extra-articular fractures in older children is a reliable option regardless of the stage of skeletal maturity. Determinants of a good outcome include optimal pinning technique with adequate pin spread at the fracture site and bicolumnar fixation. LEVEL OF EVIDENCE: Level IV-retrospective case series.

Complications of type II supracondylar humerus fractures treated at a specialized paediatric centre.

BACKGROUND: Supracondylar humerus (SCH) fractures are the most common operatively treated paediatric fracture in Canada. Previous literature describing the low-energy (Gartland type II) subtype reports varying complication rates from a variety of practice settings. We sought to examine complications of type II SCH fractures treated at a Canadian specialized paediatric centre. METHODS: We conducted a retrospective cohort study of patients aged 0 to 14 admitted to SickKids, Toronto, Ontario for surgical treatment of a type II SCH fracture from 2008 to 2015. The primary outcome of this study was relevant perioperative complications including: open fracture, compartment syndrome, pre- and postoperative vascular compromise, pre- and postoperative neurological compromise, failure to obtain a closed reduction (i.e., open reduction), postoperative infection, and reoperation within 3 months. RESULTS: There were 370 patients included in the study with mean (standard deviation) age 5.14 years (±2.51). The overall rate of relevant complications in the study cohort was 3.6% (13/358, 12 missing), with 12 cases of nerve palsy (3.3%; 2 iatrogenic [0.6%]) that resolved by final follow-up and one case of preoperative nerve palsy (0.3%) that did not. Importantly, there were no cases of vascular compromise, open fracture, compartment syndrome, or infection. DISCUSSION AND CONCLUSION: Complications associated with type II SCH fractures managed at a specialized paediatric centre that result in long-term morbidity are extremely rare (0.3%). Perioperative inpatient monitoring for patients with these fractures may not be justified based on these data. Prospective studies are required to confirm safety, evaluate patient perspectives, and demonstrate cost savings of outpatient surgical management.

Establishing Safe Zones to Avoid Nerve Injury in the Approach to the Humerus in Pediatric Patients: A Magnetic Resonance Imaging Study.

BACKGROUND: The surgical anatomy of upper-extremity peripheral nerves in adults has been well described as "safe zones" or specific distances from osseous landmarks. In pediatrics, relationships between nerves and osseous landmarks remain ambiguous. The goal of our study was to develop a model to accurately predict the location of the radial and axillary nerves in children to avoid iatrogenic injury when approaching the humerus in this population. METHODS: We conducted a retrospective review of 116 magnetic resonance imaging (MRI) scans of entire humeri of skeletally immature patients; 53 of these studies met our inclusion criteria. Two independent observers reviewed all scans. Arm length was measured as the distance between the lateral aspect of the acromion and the lateral epicondyle. We then calculated the distances (defined as the percentage of arm length) between the radial nerve and distal osseous landmarks (the medial epicondyle, transepicondylar line, and lateral epicondyle) as well between the axillary nerve and the most lateral aspect of the acromion. RESULTS: The axillary nerve was identified at a distance equaling 18.6% (95% confidence interval [CI], ±0.62%) of arm length inferior to the lateral edge of the acromion. The radial nerve crossed (1) the medial cortex of the posterior part of the humerus at a distance equaling 63.19% (95% CI: ±0.942%) of arm length proximal to the medial epicondyle, (2) the middle of the posterior part of the humerus at a distance equaling 53.9% (95% CI: ±1.08%) of arm length proximal to the transepicondylar line, (3) the lateral cortex of the posterior part of the humerus at a distance equaling 45% (95% CI: ±0.99%) of arm length proximal to the lateral epicondyle, and (4) from the posterior to the anterior compartment at a distance equaling 35.3% (95% CI: ±0.92%) of arm length proximal to the lateral epicondyle. A strong linear relationship between these distances and arm length was observed, with an intraclass correlation coefficient of >0.9 across all measurements. CONCLUSIONS: The positions of the radial and axillary nerves maintain linear relationships with arm lengths in growing children. The locations of these nerves in relation to palpable osseous landmarks are predictable. CLINICAL RELEVANCE: Knowing the locations of upper-extremity peripheral nerves as a proportion of arm length in skeletally immature patients may help to avoid iatrogenic injuries during surgical approaches to the humerus.

Cost savings of implementing the SickKids Paediatric Orthopaedic Pathway for proximal humerus fractures in Ontario, Canada.

BACKGROUND: The SickKids Paediatric Orthopaedic Pathway (SKPOP) for proximal humerus fractures may safely reduce the number of radiographs and follow-up assessments for children with these injuries. The study objective was to examine potential cost-savings of the SKPOP from the perspective of the Ministry of Health and Long-term Care (MOHLTC). METHODS: Two sets of resource profiles, based on direct health care costs were created for a cohort of patients treated at our institution: the first based on actual follow-up assessment values, and the other based on follow-up assessments according to the SKPOP. Differences between the two profiles represent potential cost-savings. A decision-analysis and associated probabilistic sensitivity analysis (PSA) were performed. RESULTS: In a cohort of 239 patients treated between 2009 and 2014, 92.9% (222) would have met SKPOP eligibility. Management according to this pathway would have reduced orthopaedic assessments and shoulder radiograph series by 83.6% (470/562) and 70.8% (367/589), respectively. For the cohort examined, a potential cost-savings of $30,040.56 ($135.32/patient) was observed. A PSA, accounting for variable SKPOP adherence and health care utilization, yielded cost-savings in 96.5% of the iterations run through the decision-analysis model and an average cost-savings of $57.82/patient. Based on these results and the annual provincial incidence rate of eligible patients (n=575), the MOHLTC could potentially save $33,249.45 annually with province-wide implementation. CONCLUSIONS: Implementation of the SKPOP for a cohort of patients managed at our institution could have resulted in cost-savings due to substantial reductions in health care utilization. Cost-savings are likely to occur with provincial implementation of the SKPOP for proximal humerus fractures.

Impact of web-based clinical practice guidelines on paediatric fracture clinics.

BACKGROUND: In an effort to standardize management and reduce over-treatment of uncomplicated paediatric fractures, the Victorian Pediatric Orthopaedic Network and the Royal Children's Hospital, Melbourne, created publically available web-based paediatric fracture pathways. The aim of this study was to determine the impact of web-based fracture pathways on the clinic volume at a tertiary-care paediatric fracture clinic. METHODS: A comparative retrospective review was performed at a large, urban, tertiary-care children's hospital. Fracture clinic data from two 12-week periods before and after implementation of the fracture pathways were compared. For each study period, data collected included: total number of emergency department visits, number of fracture clinic visits, number of fracture clinic visits for patients that presented with upper extremity fractures for which web-based fracture pathways were available, number of radiology department visits for X-rays, and number of fracture clinic visits for patients requiring orthopaedic intervention in the operating room (closed or open reductions). RESULTS: The number of fracture clinic visits for patients with upper extremity fractures decreased 12% post-pathway implementation, from 954 visits to 842 visits. The number of radiology department visits for patients with upper extremity fractures decreased 24% post-pathway implementation, from 714 to 544 visits. CONCLUSION: The implementation of web-based fracture pathways for upper extremity paediatric fractures was associated with a decrease in clinic resource utilization at a tertiary-care children's hospital.

Do toddler's fractures of the tibia require evaluation and management by an orthopaedic surgeon routinely?

OBJECTIVE: The majority of uncomplicated toddler fractures of the tibia (toddler's fractures) do not need an orthopaedic surgeon's intervention or follow-up. However, inexperienced emergency room physicians, general practitioners and orthopaedic trainees and surgeons understandably defer to a cautious approach of referral and subsequent frequent clinical and radiographic follow-up. An evidence-based pathway can help prevent this overtreatment, reduce unnecessary radiation exposure and decrease the financial burden on families and the healthcare system. PATIENTS AND METHODS: A retrospective analysis of patients who presented for management of toddler's fractures to The Hospital for Sick Children (SickKids) was performed. RESULTS: A total of 184 (113 boys, 72 girls) patients, of a mean age of 1.99 (range: 0.2-3.9) years, were included for review. The included patients had attended 2.00±1.0 clinic visits and had had 5.86±2.7 radiographs taken on average. No complications such as cast injuries, nonunion, refracture or subsequent deformity needing assessment or intervention were identified. CONCLUSION: Toddler's fractures do not require routine orthopaedic surgeon assessment, intervention or follow-up. If diagnosed and managed correctly at initial presentation, patients with toddler's fractures may be discharged safely without the need for further clinician contact. We developed a toddler's fracture clinical care pathway to reduce unnecessary orthopaedic surgeon referral and clinical and radiographic follow-up, thereby decreasing radiation exposure and costs to families and the healthcare system without risking patient outcomes.

Informal regionalization of pediatric fracture care in the Greater Toronto Area: a retrospective cross-sectional study.

BACKGROUND: Operative management of pediatric fractures is an expected competency in the specialty of Orthopedic Surgery. However, specialized pediatric centres may be providing care for increasing numbers of patients with fractures previously treated at community hospitals. The primary objective of this study was to examine trends in presentation of children with fractures to a specialized pediatric centre. METHODS: We performed a detailed chart review to examine trends in presentation of children aged 14 years or less with supracondylar humerus or femur fractures to a specialized pediatric centre (Hospital for Sick Children, Toronto) from anywhere in the Greater Toronto Area between Apr. 1, 2008, and Mar. 31, 2015. Consecutive patients admitted to hospital and requiring operative intervention for a supracondylar humerus or femur fracture were considered. We calculated changes in operation incidence rates per year using multivariable negative binomial regression models. RESULTS: A total of 945 children with supracondylar humerus fractures and 421 with femur fractures underwent operative intervention during the study period. The baseline characteristics of the 2 groups were similar irrespective of which year fixation occurred. The annual incidence rate of supracondylar humerus fractures increased from 108 to 169 (56.5%) over the study period, at an adjusted rate of 7.5% per year (adjusted incidence rate ratio [IRR] 1.075, 95% confidence interval [CI] 1.072-1.079, p < 0.001). The annual incidence rate of femur fractures increased from 49 to 69 (40.8%), at an adjusted rate of 5.3% per year (adjusted IRR 1.053, 95% CI 1.044-1.062, p < 0.001). Significant increases were observed independent of fracture classification, stabilization method, whether patients were transferred from an outside hospital or presented directly, patient geographic location or the season in which the fracture occurred. INTERPRETATION: Adjusted annual incidence rates of supracondylar humerus and femur fractures increased significantly over the study period. Further work is needed to assess the clinical impact of informal regionalization of care and to determine whether the phenomenon occurs in other specialties.

Patient views on financial relationships between surgeons and surgical device manufacturers.

BACKGROUND: Over the past decade, revelations of inappropriate financial relationships between surgeons and surgical device manufacturers have challenged the presumption that surgeons can collaborate with surgical device manufacturers without damaging public trust in the surgical profession. We explored postoperative Canadian patients' knowledge and opinions about financial relationships between surgeons and surgical device manufacturers. METHODS: This complex issue was explored using qualitative methods. We conducted semistructured face-to-face interviews with postoperative patients in follow-up arthroplasty clinics at an academic hospital in Toronto, Canada. Interviews were audiotaped, transcribed and analyzed. Patient-derived concepts and themes were uncovered. RESULTS: We interviewed 33 patients. Five major themes emerged: 1) many patients are unaware of the existence of financial relationships between surgeons and surgical device manufacturers; 2) patients approve of financial relationships that support innovation and research but are opposed to relationships that involve financial incentives that benefit only the surgeon and the manufacturer; 3) patients do not support disclosure of financial relationships during the consent process as it may shift focus away from the more important risks; 4) patients support oversight at the professional level but reject the idea of government involvement in oversight; and 5) patients entrust their surgeons to make appropriate patient-centred choices. CONCLUSION: This qualitative study deepens our understanding of financial relationships between surgeons and industry. Patients support relationships with industry that provide potential benefit to current or future patients. They trust our ability to self-regulate. Disclosure combined with appropriate oversight will strengthen public trust in professional collaboration with industry.

CONTEXTE: Ces 10 dernières années, la mise en lumière de relations financières inappropriées entre des chirurgiens et des fabricants de matériel chirurgical a remis en doute la capacité des chirurgiens à collaborer avec les fabricants et ébranlé la confiance du public en la profession. Nous avons étudié ce que les patients canadiens ayant récemment été opérés pensent et connaissent des relations financières entre les chirurgiens et les fabricants de matériel chirurgical. MÉTHODES: Nous avons mené une étude qualitative portant sur cette question complexe au moyen d'entrevues semi-dirigées effectuées en personne avec des patients qui assistaient, dans un hôpital universitaire de Toronto (Canada), à des rencontres postopératoires à la suite d'une arthroplastie. Les entrevues ont été enregistrées, transcrites, puis analysées, ce qui a mis au jour des notions et des thèmes issus des patients. RÉSULTATS: Nous avons interrogé 33 patients et dégagé 5 grandes conclusions : 1) de nombreux patients ignorent l'existence de relations financières entre les chirurgiens et les fabricants de matériel chirurgical; 2) les patients acceptent les relations financières qui soutiennent l'innovation et la recherche, mais rejettent celles qui ne profitent qu'aux chirurgiens et aux fabricants; 3) les patients ne veulent pas que les relations financières soient divulguées pendant le processus de consentement, car une telle divulgation pourrait détourner l'attention des risques plus importants; 4) les patients sont d'accord pour qu'une surveillance soit exercée par l'ordre professionnel, mais pas par le gouvernement; 5) les patients font confiance aux chirurgiens et croient qu'ils font des choix axés sur leurs patients. CONCLUSION: Cette étude qualitative approfondit notre compréhension des relations financières entre les chirurgiens et les autres acteurs du domaine. Les patients soutiennent ce type de relations pourvu qu'elles puissent profiter aux patients actuels et futurs, et croient en notre capacité d'autoréglementation. Ensemble, la divulgation de ces relations et une surveillance appropriée renforceront la confiance du public en la collaboration entre les professionnels et les entreprises.

Patients' views on surgeons' financial conflicts of interest.

BACKGROUND: The U.S. Department of Justice's investigations into financial relationships between surgical device manufacturers and orthopaedic surgeons have raised the question as to whether surgeons can continue to collaborate with industry and maintain public trust. We explored postoperative patients' views on financial relationships between surgeons and surgical device manufacturers, their views on disclosure as a method to manage these relationships, and their opinions on oversight. METHODS: From November 2010 to March 2011, we surveyed 251 postoperative patients in the U.S. (an 88% response rate) and 252 postoperative patients in Canada (a 92% response rate) in follow-up hip and knee arthroplasty clinics with use of self-administered questionnaires. Patients were eligible to complete the questionnaire if their surgery (primary or revision hip or knee arthroplasty) had occurred at least three months earlier. RESULTS: Few patients are worried about possible financial relationships between their surgeon and industry (6% of surveyed patients in the U.S. and 6% of surveyed patients in Canada). Most patients thought that it is appropriate for surgeons to receive payments from manufacturers for activities that can benefit patients, such as royalties for inventions (U.S., 69%; Canada, 66%) and consultancy (U.S., 48%; Canada, 53%). Most patients felt that it is not appropriate for their surgeon to receive gifts from industry (U.S., 63%; Canada, 59%). A majority felt that their surgeon would hold patients' interests paramount, regardless of any financial relationship with a manufacturer (U.S., 76%; Canada, 74%). A majority of patients wanted their surgeon's professional organization to ensure that financial relationships are appropriate (U.S., 83%; Canada, 83%); a minority endorsed government oversight of these relationships (U.S., 26%; Canada, 35%). CONCLUSIONS: Most patients are not worried about possible financial relationships between their surgeon and industry. They clearly distinguish financial relationships that benefit current or future patients from those that benefit the surgeon or device manufacturer. They favor disclosure with professional oversight as a method of managing financial relationships between surgeons and manufacturers.
