[A prospective study of super-thin anterolateral thigh flap harvesting assisted by high-frequency color Doppler ultrasound in detecting perforators in deep adipose layers].

Objective: To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF). Methods: Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19.6 to 36.2 kg/m 2, with an average of 23.62 kg/m 2. The causes of injury included traffic accident injury in 15 cases, heavy object crush injury in 20 cases, mechanical injury in 8 cases, heat crush injury in 1 case, and chronic infection in 1 case. There were 20 cases on the left side, 24 cases on the right side, and 1 case on both sides. After thorough debridement, the wound size ranged from 5 cm×4 cm to 17 cm×11 cm. All patients underwent free super-thin ALTF transplantation repair. HFCDU was used to detect the location of the perforators piercing the deep and superficial fascia, as well as the direction and branches of the perforators within the deep adipose layers before operation. According to the preoperative HFCDU findings, the dimensions of the super-thin ALTF ranged from 6 cm×4 cm to 18 cm×12 cm. The donor sites of the flaps were directly sutured. Results: A total of 55 perforators were detected by HFCDU before operation, but 1 was not found during operation. During operation, a total of 56 perforators were found, and 2 perforators were not detected by HFCDU. The positive predictive value of HFCDU for identifying perforator vessels was 98.2%, and the sensitivity was 96.4%. Among the 54 perforators accurately located by HFCDU, the orientation of the perforators in the deep adipose layers was confirmed during operation. There were 21 perforators (38.9%) traveled laterally and inferiorly, 12 (22.2%) traveled medially and inferiorly, 14 (25.9%) traveled laterally and superiorly, 5 (9.3%) traveled medially and superiorly, and 2 (3.7%) ran almost vertically to the body surface. Among the 54 perforators accurately located by HFCDU, 35 were identified as type 1 perforators and 12 as type 2 perforators (HFCDU misidentified 7 type 2 perforators as type 1 perforators). The sensitivity of HFCDU in identifying type 1 perforators was 100%, with a positive predictive value of 83.3%. For type 2 perforators, the sensitivity was 63.2%, and the positive predictive value was 100%. The surgeries were successfully completed. The super-thin ALTF had a thickness ranging from 2 to 6 mm, with an average of 3.56 mm. All super-thin ALTF survived, however, 1 flap experienced a venous crisis at 1 day after operation, but it survived after emergency exploration and re-anastomosis of the veins; 1 flap developed venous crisis at 3 days after operation but survived after bleeding with several small incisions; 3 flaps had necrosis at the distal edge of the epidermis, which healed after undergoing dressing changes. All 45 patients were followed up 6-18 months (mean, 13.6 months). Three flaps required secondary defatting procedures, while the rest had the appropriate thickness, and the overall appearance was satisfactory. Conclusion: Preoperative application of HFCDU to detect the perforator in the deep adipose layers can improve the success and safety of the procedure by facilitating the harvest of super-thin ALTF.

Soft tissue injury prediction using joint depression in computed tomography in AO 41B lateral tibial plateau fractures.

Tibial plateau fractures are usually associated with soft tissue injury. This study aimed to use the extent of joint depression and lateral widening in computed tomography (CT) to predict the soft tissue injury accompanying fractures.The study included 23 patients with type Arbeitsgemeinschaft für Osteosynthesefragen-classified 41B fractures. Demographics, mechanism of injury, age, gender, and injury sites were assessed. Post-traumatic radiography, magnetic resonance imaging (MRI), and CT were obtained. MRI evaluated the meniscal, cruciate, and collateral ligament injuries, and CT measured the extent of joint depression and lateral widening in millimeters using digital imaging software. The relationship between joint depression, lateral widening, and soft tissue injuries was statistically analyzed. Of the 23 patients, 17 (74%) were males and 6 (26%) were females. Lateral meniscus injuries increased and the risk of bucket handle lateral meniscus tears increased as the CT joint depression exceeded 12 mm (p < 0.05). Joint depression of <5.9 mm was associated with medial meniscus injury (p < 0.05). The mean distribution examination of all soft tissue injuries and joint depression revealed no statistically significant difference between the groups (p > 0.05). Increased joint depression in lateral tibial plateau fractures increases the risk of lateral meniscus bucket handle tear, and decreased joint depression increases the risk of medial meniscus injury. Accordingly implementing the treatment plan and patient management will improve the clinical outcomes.

A clinical study of ultrasonic localization-assisted combined transplantation of a bilateral anterolateral thigh perforator flap for the repair of large-area skin and soft tissue defects of the extremities.

OBJECTIVE: The aim of this study was to investigate the clinical efficacy of the combined transplantation of a bilateral anterolateral thigh perforator (ALTP) flap for the repair of large-area skin and soft tissue defects of the extremities. PATIENTS AND METHODS: Twelve patients who had received bilateral ALTP flap reconstructions for large-area skin and soft tissue defects of the extremities were retrospectively analyzed. The areas of the skin and soft tissue defects were measured preoperatively (18.0×11.0 ‒ 38.0×15.0 cm2). The wounds were on the forearm, elbow, upper arm, foot, and lower leg. Color Duplex Sonography (CDS) was used to localize the site where the perforator artery of the bilateral thighs penetrated the deep fascia. The selected area was evaluated according to the number of perforating branches and the range of supply. The flap areas and repairable range were further evaluated according to the number of perforating branches detected during the operation to determine whether to retain the deep fascia. It is important to design and adjust the anastomosis of the vascular pedicle according to the specific situation on transfer of the flap to the recipient site. The donor sites of all the patients in the study were closed in the first stage. The amount of bleeding and the blood supply to the flap after vascular anastomosis were evaluated during the operation. The postoperative survival of the flap and complications, such as bleeding, infection, and arteriovenous crisis, were closely monitored. All patients were followed-up at one, three, and six months after surgery to assess their satisfaction with the appearance of the flap transplantation and the recovery of limb function. RESULTS: The bilateral ATLP flaps survived successfully in all 12 cases and all donor sites were closed in the first stage. No post-surgery complications, including hematoma, wound dehiscence, and infection, were observed at the donor sites, resulting in high patient satisfaction. CONCLUSIONS: Combined transplantation of bilateral ALTP flaps can repair large-area skin and soft tissue defects in one stage, which not only reduces the number of operations and hospitalization costs but also reduces the damage to the limbs caused by the cutting of large-area flaps from only one side. The accuracy of the surgery was improved by ultrasound-assisted localization. In summary, combined transplantation of bilateral ALTP is a rational yet effective way to repair large-area skin and soft tissue defects of the extremities.

Three-Dimensional Digitalized Virtual Planning of Free Anterior Tibial Artery Perforator Flap for Repairing Soft Tissue Defects in Extremities.

BACKGROUND: Traditional research methods have limited the application of anterior tibial artery perforator flap due to incomplete knowledge of the perforator. This study aimed to investigate the feasibility of three-dimensional digitalized virtual planning of free anterior tibial artery perforator flap for repairing soft tissue defects in extremities. METHODS: A total of 11 patients with soft tissue defects in extremities were included. The patient underwent computed tomography angiography (CTA) of bilateral lower limbs, and then the three-dimensional models of bones, arteries, and skin were constructed. Septocutaneous perforators with appropriate length and diameter were selected to design anterior tibial artery perforator flaps in software, and the virtual flaps were superimposed onto the patient's donor site in a translucent state. During the operation, the flaps were dissected and anastomosed to the proximal blood vessel of the defects as designed. RESULTS: Three-dimensional modeling showed clear anatomical relationships between bones, arteries, and skin. The origin, course, location, diameter, and length of the perforator obtained during the operation were consistent with those observed preoperatively. Eleven anterior tibial artery perforator flaps were successfully dissected and transplanted. Postoperative venous crisis occurred in one flap, partial epidermis necrosis occurred in another flap, while the remaining flaps completely survived. One flap was treated with debulking operation. The remaining flaps maintained aesthetic appearance, which did not affect the function of the affected limbs. CONCLUSIONS: Three-dimensional digitalized technology can provide comprehensive information on anterior tibial artery perforators, thus assisting in planning and dissecting patient-specific flaps for repairing soft tissue defects in extremities.

Morel-Lavallee lesions. Size matters? Treatment and time of disability.

INTRODUCTION: Degloving soft-tissue injuries are serious and potentially devastating medical conditions where an early recognition is a crucial step for a favorable outcome. One of the most important types is Morel-Lavallée lesions (MLL); a significant soft-tissue injury associated with pelvic trauma (30%) and thigh (20%), located over the greater trochanter. MATERIAL AND METHODS: In this retrospective study we selected adult patients diagnosed with MLL between 2010 and 2019 at our trauma center. We then identified 9 cases and followed them up for a minimum of two years. CT scans were performed to measure the size of the degloved zone. RESULTS: we did not found direct relationship between greater dimensions of MLL injury and the need for an increase of days to return to work. We rather identified an association between bigger dimensions of MLL injury and higher energy trauma. These patients waited an average of 133 days to return to work after being injured; which is a longer period compared to non-op patients. DISCUSSION: MLL lesions generally take several days to develop and many may be missed on initial evaluation. Once identified, compression dressings should be applied, especially when diagnosed acutely. Early identification would lead to early operative debridement. Also, drainage should be performed, since the pathophysiology of the injury will result in the failure of observation or simple aspiration. CONCLUSION: MLL diagnosis and treatment must be identified as early as possible. We didn't find a correlation between MLL size and the treatment performed. In our study all patients returned to their jobs and normal life. Patients following conservative treatment take longer time to recover and could require more patient's implication, but -at least- would avoid possible surgical complications.

Ten-year incidence and treatment outcomes of closed degloving injuries (Morel-Lavallee lesions) in a level 1 trauma centre.

INTRODUCTION: Morel-Lavallée lesions (MLL), also referred to as closed degloving injuries, result from traumatic shearing forces with separation of the subcutaneous fat from the underlying fascia. The aim of this study was to determine the incidence and treatment of MLLs at a level 1 trauma centre. METHODS: Single-centre retrospective cross-sectional study of consecutive patients with an imaging diagnosis of a Morel-Lavallee lesion from 1/1/2010-31/12/2019. Demographic data, mechanism of injury, volume of lesion, management and outcome data were collated. RESULTS: Sixty-six MLLs were identified in 63 patients (64% Male) with a median age of 49.5 years (19-94 years). Mechanism of injury were road traffic accidents in the majority (66%). Median injury severity score (ISS) was 17 (range 1-33). Patients on oral anti-coagulants had significantly larger lesions (181.9 cc v 445.5 cc, P = 0.044). The most common lesion location was the thigh (60.5%). Patients that underwent imaging within 72 h of injury had significantly larger lesions than those imaged more than 72 h after the inciting trauma (65 cc v 167 cc, P < 0.05). Management data were documented in 59% of lesions (39/66) in which 66.6% (n = 26) had invasive treatment. In the 31 patients where follow-up was available, 64.5% (n = 20) were persistent but decreasing in size. There was no significant difference in follow-up size for those who had invasive compared to conservative treatment (P = 0.3). CONCLUSION: The diagnosis of MLL should be considered for soft-tissue swelling in the context of shearing trauma. A variety of management options have been employed, with good overall outcomes.

Application of Low-Dose CT and MRI in the Evaluation of Soft Tissue Injury in Tibial Plateau Fractures.

Objective: To explore the application value of low-dose CT and MRI in the evaluation of soft tissue injury in tibial plateau fractures. Methods: This study included 89 patients with high suspicion of TPF and KI admitted to our hospital from July 2015 to May 2021. After arthroscopy, 81 patients were diagnosed with FTP combined with KI. The Schatzker classification based on X-ray and CT plain scan combined with three-dimensional reconstruction was recorded, and the soft tissue injury was recorded according to the MRI examination of the affected knee joint. Results: With the results of pathological examination and arthroscopic surgery as the gold standard, the results of MRI and pathological examination and arthroscopic examination were in good agreement (Kappa = 0.857, 0.844), and CT was moderately in agreement (Kappa = 0.697, 0.694). In KI examination, CT and MRI had no difference in the evaluation of ligament injury and bone injury (P > 0.05), but MRI had better diagnostic effect on meniscus injury (P < 0.05). Finally, the satisfaction survey showed that patients in the CT group were more satisfied with clinical services (P < 0.05). Conclusion: Both CT and MRI have certain diagnostic value for occult tibial plateau fractures, among which CT examination is more advantageous for trabecular bone fractures, MRI examination is more advantageous for cortical bone fractures, and MRI examination can improve occult tibial plateau fracture inspection accuracy.

[Imaging study and clinical application of peroneal perforating chimeric tissue flap].

Objective: To explore the feasibility of peroneal perforating chimeric tissue flap in repairing the composite defects of calf and heel based on lower limb angiography, and the clinical effect. Methods: The digital subtraction angiography images of lower limbs of 50 patients met the selection criteria between May 2011 and October 2014 were used as the research object to observe the course of peroneal artery and its perforating vessels. Based on the observation results, between April 2015 and October 2020, the peroneal perforating chimeric tissue flap was designed to repair 7 cases of composite defects of the calf and heel. There were 5 males and 2 females with an average age of 38 years (range, 25-55 years). The causes of injury included traffic accident in 4 cases, falling from height in 2 cases, and machine strangulation in 1 case. There were 5 cases of calf skin defect and tibial defect. The size of skin defect ranged from 5 cm×3 cm to 11 cm×7 cm, and the length of bone defect was 5-8 cm. There were 2 cases of heel skin defect and calcaneal defect. The sizes of skin defects were 5.0 cm×4.0 cm and 7.5 cm×6.5 cm, and the bone defects were 3.0 cm×2.6 cm and 4.0 cm× 3.0 cm. For the calf defect, the size of skin flap ranged from 6 cm×4 cm to 12 cm×8 cm, and the length of the fibula was the same as that of the tibial defect. For the heel defect, the sizes of the skin flaps were 8.5 cm×5.5 cm and 13.0 cm×5.0 cm, and the lengths of the fibulae were 10 cm and 12 cm. Free transplantation was performed in 5 cases and pedicle transplantation in 2 cases. The wound at donor site was repaired with skin grafting or sutured directly. Results: The peroneal artery ran close to the fibula 7.25-8.40 cm below the fibula head and send out 5-7 perforating vessels, with an average of 6.5 vessels. Perforating vessels mainly appeared in four places, which were (9.75±0.91), (13.21±0.74), (18.15±1.22), and (21.40±0.75) cm below the fibular head, with the occurrence rates of 94%, 90%, 96%, and 88%, respectively. Clinical application of 7 cases of peroneal perforating chimeric tissue flap all survived, all wounds healed by first intention. The skin graft at donor site survived and the incision healed by first intention. All patients were followed up 6-36 months, with an average of 12 months. Peroneal perforator chimeric tissue flap had good shape and soft texture. X-ray films showed that the bone graft healed well, and the healing time was 6-11 months (mean, 7 months). No obvious bone resorption was observed during follow-up. Five patients had no pain when walking, and 1 had mild pain with claudication. Postoperative heel ulcers formed in 1 case and healed after wearing custom plantar pressure dispersing shoes. At 6 months after operation, 2 patients were rated as grade Ⅳ and 5 patients as grade Ⅴ according to Holden walking function score. Conclusion: The peroneal perforating vessel distribution is constant and the peroneal perforating chimeric tissue flap is safe and reliable for repairing the composite defects of calf and heel.

MRI in acute simple elbow dislocations: correlation of preoperative imaging and intraoperative findings of collateral ligaments and associated soft tissue injuries.

PURPOSE: The aim of our study was the evaluation of correspondence among collateral ligaments and other soft tissue injuries detected by MRI and by intraoperative findings in a consecutive series of patients treated for simple elbow dislocation. METHODS: After clinical and MRI examination, 16 out of 59 consecutive patients with moderate or severe instability after simple elbow dislocation were addressed to surgical treatment. There were 14 men and 2 women. The mean age was 39.6 years (range 16-69 years). RESULTS: MRI showed full-thickness lesion of MCL in 9/16 patients (53.3%) and partial lesion in 6/16 patients (40%), and in 1 case, the MCL was considered intact. On the lateral side, MRI showed complete injury of LCL in 7/16 patients (46.6%) and partial injury in 7/16 patients (40%). No lesions of LCL were observed in 2 patients (13.4%). MCL was surgically explored in all the patients. We observed 10/16 full-thickness lesions (62.5%) and 6/16 partial lesions (37.5%). LCL was surgically explored in 11/16 patients. We observed 6/11 full-thickness lesions (54.6%) and 5/11 partial lesions (45.4%). In 3 cases, associated soft tissue injuries were detected. The rate of concordance between MRI and surgical findings was 87.5% (14/16 cases) on the medial side and 90.9% (10/11 cases) on the lateral side. CONCLUSION: Our study demonstrated that MRI is a reliable and useful tool to investigate collateral ligaments and soft tissue injuries around the elbow and to plan the most adequate surgical treatment.

Acute soft tissue injury to the temporomandibular joint and posttraumatic assessment after mandibular condyle fractures: a longitudinal prospective MRI study.

OBJECTIVE: Evaluation of acute soft tissue injury of the temporomandibular joint (TMJ) with type I-VI fractures immediately after trauma and investigation of the longitudinal evolution including response to conservative treatment using MRI. METHODS: The joints of 24 patients with 33 condylar fractures (15 unilateral, nine bilateral) were imaged on a 1 Tesla MR system within the first 24 h post-trauma. 12 of these patients with 16 condylar fractures (eight unilateral, four bilateral) were clinically re-evaluated using MRI after 3 months of closed treatment. The position, morphology, and signal intensities of the disc, capsule, retrodiscal tissue, and osseous structures were documented. RESULTS: In the acute phase, disc displacements (DDs) were diagnosed in 8 out of 33 joints with fracture, including posterior DDs in two joints and tears of the inferior retrodiscal lamina in 11 joints. The follow-up MRI in 12 patients revealed new DD in four joints on the fractured side (FS) including a posterior DD and an increased degree of displacement, and new DDs in two joints in the non-fractured side (NFS). CONCLUSION: Preexisting and traumatic DD and soft tissue injuries are frequent findings in patients with condylar fracture. Independent of the degree of trauma, condylar fractures may determine the subsequent development of DD on both FS and NFS. Early MR imaging may help initiate well-directed specific measures for better outcomes in the acutely injured TMJ.

Semi-quantitative scoring of imaging modalities in detecting soft tissue foreign bodies: an in vitro study.

BACKGROUND: Accurate identification of foreign bodies (FB) using medical imaging is essential for diagnosis and determining the suitable retrieval technique. PURPOSE: To compare the sensitivity of different imaging modalities for detecting various FB materials in soft tissue and assess the reproducibility of a scoring system for grading the conspicuity of FBs. MATERIAL AND METHODS: Five FB materials (plastic, wood, glass, aluminum, and copper) were embedded in a tissue-mimicking phantom. Computed radiography (CR), ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) were compared using a semi-quantitative 5-point Likert scale scoring system. The intra- and inter-reader reproducibility of four independent readers was analyzed using Kendall's coefficient of concordance (W). RESULTS: Glass was visible on all imaging modalities. Plastic was only visible in excellent detail using ultrasound. Wood was detected in excellent resolution using ultrasound and CT using the default window while plain X-ray failed to detect it. Ultrasound was the only modality that showed aluminum in excellent quality while CT showed it with good demarcation from the surroundings. Copper was detectable in excellent detail using CR, ultrasound, and CT. MRI performance was suboptimal, especially with the plastic FB. The scoring system showed excellent intra-reader (W = 0.91, P = 0.001) and inter-reader (W = 0.88, P < 0.001) reproducibility. CONCLUSION: Ultrasound can be used as the first line of investigation for wood, plastic, glass, and metallic FBs impacted at superficial depths in soft tissue. The semi-quantitative FB scoring system showed excellent within- and between-reader reliability, which can be used to score and compare the detection performance of new imaging techniques.

Strategy of harvesting extended thoracodorsal artery perforator flaps for resurfacing the large soft-tissue defects of extremities.

BACKGROUND: The authors presented their strategy to harvest extended thoracodorsal artery (TDA) perforator flaps for resurfacing the large soft-tissue defects of extremities. MATERIALS AND METHODS: Thirty-three free extended TDA perforator flaps were harvested in 33 patients. The mean flap size was 145.2 cm2. The maximal flap length and the width were 30 cm and 10 cm, respectively. The color Doppler sonography (CDS) was used for preoperative assessment of perforators. Indocyanine green angiography (ICGA) was used for intraoperative assessment of flap viability in three patients. RESULTS: The vascular thrombosis, donor-site scar widening, and delayed recipient-site wound healing were not significantly related to the patient and flap characteristics. Flap tip or partial necrosis was significantly related to age and peripheral vascular disease. True positive rate, false negative rate, and positive predictive value of CDS for perforator identification were not different significantly between attending surgeon and residents. In the distance discrepancy of CDS, significant difference was found based on the classifications of perforator size, perforator type, and sonographic operator. The ICGA identified a hypoperfused distal area in a 30 cm long flap. CONCLUSION: The CDS locates the TDA perforators more precisely when scanned by experienced hands, in larger size or septocutaneous perforators. Using reliable and more perforators, applying muscle-sparing technique, considering suprafascial course of perforator and proper flap orientation are helpful in harvesting extended TDA perforator flaps. ICGA is an option for assessing flap viability, especially in elders and patients with peripheral vascular diseases.

The pivot fracture: an unusual tibial plateau fracture found in association with acute ACL injury.

Tibial plateau fractures are common fractures which are often associated with concurrent soft tissue injury and for which accurate preoperative diagnosis is important for development of an appropriate treatment plan and outcome prediction. Here, we present an extreme manifestation of the pivot shift phenomenon with an unusual tibial plateau fracture with flipped component not described by any existing tibial plateau fracture classification system and never reported previously in conjunction with an anterior cruciate ligament injury. We describe the utilization of advanced imaging not typically utilized in the management of tibial plateau fractures in combination with clinical suspicion to diagnose the associated soft tissue injuries and develop an appropriate management plan.

Knee Ligament Imaging: Preoperative and Postoperative Evaluation.

Preoperative and postoperative imaging of knee ligament injury hinges on the appropriate use of available modalities. Knowledge of injury patterns as well as the surgical significance of certain image findings enhances injury detection and supports appropriate preoperative planning. The radiologist must be familiar with the strengths and weaknesses of each modality for evaluating specific aspects of ligamentous pathology. This article focuses on preoperative and postoperative imaging of knee ligament injury. Basic topics pertaining to preoperative image modality selection and isolated injury detection are addressed. More advanced areas including ligamentous injury patterns, surgical indications, and postoperative imaging are also discussed.

[Swelling of the thigh after a scooter accident]. / Zwelling van het bovenbeen na een scooterongeval.

A 44-year-old man presented with a swelling of his right thigh three weeks after a fall of his scooter, in which he had experienced a sheering trauma on the tarmac. The painless swelling had increased gradually to a size of 20 x 10 cm. Ultrasonography showed a fluid filled separation of the subcutis and fascia. The diagnosis was a Morel-Lavallee lesion.

Huge scalp Morel-Lavallée lesion with eye involvement in a 3-year-old girl: a case report.

BACKGROUND: Morel-Lavallée lesions are posttraumatic, closed degloving injuries in which the skin and subcutaneous tissue are separated abruptly from superficial underlying fascia. This condition leads to an effusion containing hemolymph and necrotic fat. Magnetic resonance imaging, when available, is the modality of choice in the evaluation of Morel-Lavallée lesion. Early diagnosis and management is essential as any delay in diagnosis or missed lesion will lead to the effusion becoming infected or leading to extensive skin necrosis. We present a condition of a Morel-Lavallée lesion involving the scalp and complicated by conjunctival chemosis. CASE PRESENTATION: We report on a 3-year-old black African girl who presented a fluctuant swelling of entire scalp, extending to upper part of the face on the seventh day after a forehead trauma due to falling on a rock while playing. Skull x-ray revealed soft-tissue swelling, giving an impression of large fluid collection in the deep subcutaneous tissues with no bone fracture. A diagnosis of Morel-Lavallée lesion of the scalp complicated by conjunctival chemosis was made. The patient was managed with percutaneous drainage and compression bandage. The patient improved well and was subsequently discharged without any vision impairment. There was no recurrence of the lesion on follow-up. CONCLUSIONS: The Morel-Lavallée lesion of the scalp complicated with conjunctival chemosis is a rare presentation of this condition. Prompt diagnosis and management are crucial for preventing complications. Image-guided diagnosis and treatment still remain a challenge in the setting of low-resource health facilities.
