Clubfoot care in low-income and middle-income countries: from clinical innovation to a public health program.

BACKGROUND: Clubfoot occurs in nearly 1 in every 1,000 live births worldwide, representing a significant burden of disease. In high-income countries, an evidence-based treatment protocol utilizing sequential casting was pioneered by Ponseti and has resulted in excellent outcomes among children treated for this condition. However, treatment methods and results of treatment vary greatly across low- and middle-income countries (LMICs). Our goal was to create a framework for understanding how effective programs that treat clubfoot in LMICs choose and organize their activities. METHODS: A systematic literature review was conducted using the keywords "developing countries" and "clubfoot." A public health analysis model known as the Care Delivery Value Chain (CDVC) was applied to discover public health practices that would optimize value over the entire course of a patient's life. RESULTS: The literature review yielded 32 unique results, seven of which met our inclusion and exclusion criteria. Review of the bibliographies yielded two additional papers for a total of nine papers. We identified seven vital steps in the clubfoot cycle of care and constructed a CDVC. CONCLUSIONS: The analysis of this CDVC model suggests six best practices that are essential to successfully scaling up clubfoot treatment programs and ensuring excellent clinical outcomes: (1) diagnosing clubfoot early; (2) organizing high-volume Ponseti casting centers; (3) using nonphysician health workers; (4) engaging families in care; (5) addressing barriers to access; (6) providing follow-up in the patient's community. These practices must be adapted to each context. Applying them will optimize outcomes when designing public health programs that deliver clubfoot care in LMICs.

Why Make the Cut? Trochanteric Slide Osteotomy Can Improve Exposure to the Anterosuperior Acetabulum.

OBJECTIVE: To define relative increases in visual bony surface area and access to critical landmarks with the addition of a trochanteric slide osteotomy to a Kocher-Langenbeck approach. METHODS: A Kocher-Langenbeck approach followed by a trochanteric slide osteotomy was sequentially performed on 10, fresh-frozen, hemipelvectomy cadaveric specimens. Visual and palpable access to relevant surgical landmarks was recorded. Calibrated digital photographs were taken of each approach and analyzed using Image J. RESULTS: The acetabular surface area exposed was 27.66 (±6.67) cm2 for a Kocher-Langenbeck approach. This increased to and 41.82 (±7.97) cm2 with the addition of a trochanteric osteotomy. The exposed surface area was increased by 51.2% for the trochanteric osteotomy (P < 0.001). The superior margin of the acetabulum could be visualized and palpably accessed in both exposures. Access to the more anterosuperior portions of the acetabulum was consistently possible in the trochanteric osteotomy but not with the Kocher-Langenbeck approach. CONCLUSIONS: A trochanteric osteotomy may visually improve access to the most anterosuperior acetabulum but does not significantly improve surgical access to relevant portions of the superior acetabulum when compared with a Kocher-Langenbeck approach.

Does formal vs home-based physical therapy predict outcomes after ankle fracture or ankle fracture-dislocation?

Background: Ankle fractures are among the most common injuries treated by orthopaedic surgeons. Various postoperative rehabilitation strategies have been promoted, but the ability to improve patient-reported functional outcome has not been clearly demonstrated. We aim to evaluate outcomes associated with clinic-based, physical therapist-supervised rehabilitation (Formal-PT) compared to surgeon-directed rehabilitation (Home-PT). Methods: This prospective observational study included patients with operative bimalleolar or trimalleolar ankle fractures with or without dislocation (n = 80) at a Level I trauma center. Patients were prescribed PT per the surgeon's practice pattern. Patient-reported functional outcomes at 6 months and complication rates were compared between groups. Results: Of the 80 patients, 38 (47.5%) patients received Formal-PT; the remaining received Home-PT. Thirty-four patients (89.5%) attended ≥1 PT session. Number of sessions attended ranged from 1 to 36 (mean = 16). Receipt of Formal-PT did not differ by injury characteristics or demographics. Of patients with private insurance, 57% were prescribed Formal-PT vs 7% of uninsured patients (P = .033). FAAM and Combination SMFA scores at 6 months were similar between groups (Formal-PT: 69.7, 20.1; Home-PT: 70.9, 24.4; P = .868, .454, respectively). Postoperative complications were rare and equivalent between groups. Conclusions: Comparison of outcomes between patients with operatively treated displaced ankle fractures/dislocations with Formal-PT vs Home-PT showed no difference in SMFA and FAAM scores. These findings suggest patients receiving supervised PT produced a similar outcome to those under routine physician-directed rehabilitation at 6 months. The cost for therapy averaged $2012.96 per patient receiving Formal-PT.

A Preoperative Planning Tool: Aggregate Anterior Approach to the Humerus With Quantitative Comparisons.

Extensile approaches to the humerus are often needed when treating complex proximal or distal fractures that have extension into the humeral shaft or in those fractures that occur around implants. The 2 most commonly used approaches for more complex fractures include the modified lateral paratricipital approach and the deltopectoral approach with distal anterior extension. Although the former is well described and quantified, the latter is often associated with variable nomenclature with technical descriptions that can be confusing. Furthermore, a method to expose the entire humerus through an anterior extensile approach has not been described. Here, we illustrate and quantify a technique for connecting anterior humeral approaches in a stepwise fashion to form an aggregate anterior approach (AAA). We also describe a method for further distal extension to expose 100% of the length of the humerus and compare this approach with both the AAA and the lateral paratricipital in terms of access to critical bony landmarks, as well as the length and area of bone exposed.

Surgical Approaches to the Proximal Humerus: A Quantitative Comparison of the Deltopectoral Approach and the Anterolateral Acromial Approach.

BACKGROUND: Debate exists over the optimal approach for addressing fractures of the proximal humerus. The purpose of this study was to objectively quantify the surface area of the humerus exposed using the deltopectoral (DP) and anterolateral acromial (ALA) approaches and to compare visualized and palpable anatomic landmarks. METHODS: Ten arms on five fresh-frozen torsos underwent the DP and ALA approaches. The arms were positioned to simulate a supine patient and held in a fixed position. Visual and/or palpable access to relevant surgical landmarks and the myotendinous junctions were recorded. The myotendinous junctions were used as a rough approximation of consistent proximal exposure of a clinically retracted tuberosity. Landmarks were grouped into quadrants based on the location. Calibrated digital photographs of each approach were analyzed to calculate the surface area and the length of the exposed bone. RESULTS: The DP and ALA approaches exposed 22.9 ± 6.3 cm2 and 16.3 ± 6.4 cm2, respectively (P = 0.03). The DP and ALA approaches provided equivalent visual and palpable access to all landmarks in the superior and inferior quadrants. The ALA allowed improved visual (80% versus 70%) and palpable (100% versus 70%) access to the myotendinous junction of the infraspinatus in the posterior quadrant. The DP approach allowed better access to anterior quadrant structures, including improved ability to visualize the myotendinous junction of the subscapularis (100% versus zero), the subscapularis insertion (100% versus 80%), and the medial anatomic neck (100% versus 20%). Palpable access to the myotendinous junction of the subscapularis (100% versus 70%) and medial anatomic neck (100% versus 60%) was also improved with the DP. CONCLUSIONS: In a cadaver model with fixed arm position, the DP provides increased exposure to the proximal humerus and more reliable access to anterior surgical landmarks, whereas the ALA allows improved access to the most posterior aspect of the shoulder.

Management of Closed Diaphyseal Humerus Fractures in Patients With Injury Severity Score ≥17.

OBJECTIVES: The management of closed diaphyseal humerus fractures in the polytrauma patient varies widely. The aim of this study was to compare outcomes of operative and nonoperative management in this patient population. DESIGN: Single-center, retrospective cohort analysis. SETTING: Urban, Level 1 trauma center. PATIENTS: Seventy-one patients with closed diaphyseal humerus fractures, and Injury Severity Score (ISS) of ≥17, treated between 2006 and 2011 were identified. INTERVENTION: Patients were treated operatively versus nonoperatively with a functional brace by surgeon preference. MAIN OUTCOMES: Primary outcome was union. Secondary outcomes included time to union, time to release to weightbearing, and complications other than nonunion. RESULTS: There was no statistical difference between age, Injury Severity Score, or fracture type between the 2 cohorts. There was a statistically higher incidence of associated orthopaedic injury, and more specifically, lower extremity injury in the group treated with operative intervention. There was no difference in union rates (95% operative, 94% nonoperative), time to union (17 weeks operative, 15 weeks nonoperative), or complication rates between the 2 groups. Time to release to weightbearing was 3 weeks shorter in the operative group (9.3 weeks operative, 12.8 weeks nonoperative). CONCLUSIONS: Polytrauma patients with closed diaphyseal humerus fractures can be treated successfully with equivalent union rates, time to union, and complication rates when selected for conservative management techniques. The decision to undertake operative management of closed diaphyseal humerus fractures in the polytraumatized patient is multifaceted and should consider patient expectations, demographics, injury profile, and ambulatory status. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Total shoulder arthroplasty: are the humeral components getting shorter?

Each generation of total shoulder arthroplasy has improved on the previous. The newest humeral component innovation is shortening the humeral component or eliminating the stem entirely to rely on stemless fixation in the humeral metaphysis. This offers theoretical advantages of preserved bone stock, less stress shielding, eliminating the diaphyseal stress riser, ease of stem removal at revision, and humeral head placement independent from the humeral shaft axis. There are a number of short term cohorts that have shown low complication rates and outcomes similar to previous generations of stemmed humeral components. Longer term and better designed studies are needed in order for short stems and stemless components to become the standard of care.

A Comparison of Exposure Between the Classic and Modified Judet Approaches to the Scapula.

OBJECTIVES: A debate exists over the optimal approach for addressing fractures of the scapula and glenoid. The purpose of this study is to (1) quantify and compare osseous exposure using modified Judet (MJ) and classic Judet (CJ) approaches and (2) assess the change in scapular exposure after triceps release from the inferior glenoid. METHODS: Ten arms on 5 fresh-frozen torsos underwent MJ and CJ approaches. A triceps release was performed following the CJ approach in all specimens. Visual and/or palpable access to relevant surgical landmarks was recorded. Calibrated digital photographs were taken of each approach and analyzed using Image J (NIH, Bethesda, MD) to calculate the surface area of exposed bone. RESULTS: The MJ and CJ approaches exposed 16.8 (±7.58) cm(2) and 98.6 (±25.39) cm(2) of bone, respectively (P < 0.001). The full medial and lateral borders of the scapula were visualized in all approaches with mobilization of the teres minor. Palpable access to the full scapular spine was possible in all cadavers. Although the MJ and CJ approaches only allowed the inferior gleniod neck to be visualized in 1 and 2 specimens, respectively, performing a triceps release provided access to this structure. It also increased the CJ exposure by 12.6 cm(2) (P < 0.001) and allowed palpation of the anterior glenoid margin in 100% of specimens. CONCLUSIONS: In conclusion, the MJ approach allows similar access to landmarks important for reduction and fixation while exposing only 20% of the surface area typically visualized with the CJ approach.

Limited Added Value of the Posterolateral Approach.

BACKGROUND: Posterolateral tibial plateau fractures (AO/OTA 41-B or 41-C) represent a minority of proximal tibia fractures. Numerous surgical approaches have been described, each with unique variations and limitations. The purpose of this study is to quantitatively and qualitatively compare the surface area and structures exposed by four surgical approaches to the posterolateral proximal tibia. METHODS: Four published surgical approaches-direct posterolateral (DPL), transfibular (TF), posteromedial (PM), and anterolateral (AL)-were performed on 10 fresh-frozen cadavers. Once each exposure was obtained, a ruler was placed in the surgical field and calibrated digital images obtained. Overall, 10 bony and soft tissue landmarks were identified and the surgeon's ability to see or touch each landmark was recorded sequentially for each exposure. RESULTS: An average of 3.9 ± 2.7 cm(2) of posterolateral proximal tibial cortex was exposed by the DPL approach with significantly more surface area exposed by the TF, PM, and AL approaches (p < 0.01). The AL and PM approaches revealed a significantly larger area of tibial metaphysis and, when used together, consistently exposed posterior metaphyseal and intra-articular structures. CONCLUSION: A combination of the AL and PM approaches allows comparable surgical exposure to the proximal tibial when compared with two posterolateral approaches. These approaches can be employed together for reduction and fixation of injuries to the posterolateral tibial plateau and allow direct evaluation of the articular surface. Dedicated posterolateral approaches should be reserved for certain clinical situations, including proximal tibiofibular joint fracture or dislocation.

Total Elbow Arthroplasty for Distal Humerus Fractures.

Total elbow arthroplasty is a good treatment alternative for selected patients with distal humerus fractures. Its attractiveness is related to several factors, including the possibility of performing the procedure; leaving the extensor mechanism intact; faster, easier rehabilitation compared with internal fixation; and overall good outcomes reported in terms of both pain relief and function. Implant failure leading to revision surgery does happen, and patients must comply with certain limitations to extend the longevity of their implant. Development of high-performance implants may allow expanding the indications of elbow arthroplasty for fractures.

Operationalizing an orthopedic action plan for the decade of road traffic safety.

The decade of action for road traffic safety provides orthopaedic surgeons with an opportunity to contribute to policy that will improve the ability to deliver trauma care. In the previous 2 decades outcomes for orthopaedic trauma patients have improved significantly. The decade of action for road traffic safety will bring attention and funding to trauma related endeavors. The challenge before orthopaedic surgeons and orthopaedic trauma societies is to provide delivery mechanisms so that clinical care can reach populations around the globe. Organizing orthopaedic trauma care into care delivery value chains provides a tool for understanding how efficiency can be gained over the entire cycle of care from emergent management through rehabilitation and revision surgery when needed. Integrated practice units allow orthopaedic surgeons to collaborate with other trauma specialists to provide integrated care and exploit the areas of natural overlap to create trauma care systems that optimize communication for surgeons and simplify follow up for patients. By using these tools orthopaedic surgeons can deliver excellent trauma care to populations around the world.
