Pedicle morphometry analysis of main thoracic apex adolescent idiopathic scoliosis.

INTRODUCTION: Screw insertion during scoliosis surgery uses free-hand pedicle screw insertion methods. However, there is a wide variation in pedicle shapes, sizes, and morphometry, especially in scoliosis patients. CT scan pedicle measurements in main thoracic Lenke type 1 adolescent idiopathic scoliosis can help visualize this diversity. This study aimed to highlight the features of pedicle morphometry on the concave and convex sides, including pedicle diameter (width in axial and height in the sagittal plane), the depth to the anterior cortex, and Watanabe Pedicle classification in patients with main thoracic apex adolescent idiopathic scoliosis. MATERIALS AND METHODS: This study was a cross-sectional observational study of Adolescent Idiopathic Scoliosis (AIS) patients whose apex in the main thoracic patient underwent deformity correction procedures. We used a three-dimensional CT scan to evaluate pedicle morphometry on the apex vertebrae, three consecutive vertebrae above and below the apex. RESULTS: A total of 6 patients with apex main thoracic AIS with 84 pedicles consisting of 42 pedicles from each concave and convex curve were analyzed. All of the samples were female, with the mean age at the procedure being 21.2 ± 5.56. The mean cobb angle was 62° ± 23°, with the main apex between VT8-VT10. The size of the pedicle was bigger from upper to lower vertebrae. The mean pedicle depth, pedicle width, and pedicle height for the concave side were 36.06 ± 4.31 mm, 3.91 ± 0.66 mm, and 9.16 ± 1.52 mm, respectively. Meanwhile, the convex side is 37.52 ± 1.84 mm, 5.20 ± 0.55 mm, and 11.05 ± 0.70 mm, respectively. We found a significant difference between the concave and convex sides for the pedicle width and height. The concave and convex sides were mainly classified as type C (38%) and type A (50%) Watanabe pedicle. CONCLUSION: Pedicle width and pedicle height are significantly different between the concave and the convex side with convex side has better Watanabe pedicle classification. Pre-operative CT evaluation is essential for planning proper pedicle screw placement in AIS patients.

Peroneus longus autograft can be recommended as a superior graft to hamstring tendon in single-bundle ACL reconstruction.

PURPOSE: A peroneus longus tendon autograft is used in many orthopaedic procedures and it is biomechanically comparable to a hamstring tendon autograft. Despite its potential, there are few studies that have evaluated the use of the peroneus longus tendon in ACL reconstruction. The aim of this study was to compare the clinical outcome and donor site morbidity of ACL reconstruction with hamstring tendon autografts versus peroneus longus tendon autografts in patients with an isolated ACL injury. METHODS: Patients who underwent isolated single-bundle ACL reconstruction were allocated to two groups (hamstring and peroneus longus) and observed prospectively. Graft diameter was measured intraoperatively. Functional scores (IKDC, modified Cincinnati and Lysholm scores) were recorded preoperatively and 1 year after surgery. Donor site morbidities were assessed with thigh circumference measurements and ankle scoring with the AOFAS and FADI. RESULTS: Fifty-two patients (hamstring n = 28, peroneus n = 24) met the inclusion criteria. The peroneus longus graft diameter (8.8 ± 0.7 mm) was significantly larger than the hamstring diameter (8.2 ± 0.8 mm) (p = 0.012). There were no significant differences between the pre- and 1-year postoperative score between the hamstring and peroneus longus groups in the IKDC (n.s), modified Cincinnati (n.s), and Lysholm (n.s). The mean for the AOFAS was 97.3 ± 4.2 and for the FADI 98 ± 3.4 in the peroneus longus group, with a significant decrease in thigh circumference in the hamstring group (p = 0.002). CONCLUSION: Anterior cruciate ligament reconstruction with peroneus longus autografts produces a functional score (IKDC, modified Cincinnati, Lysholm) comparable to that of hamstring autografts at a 1-year follow-up, with the advantages of larger graft diameter, less thigh hypotrophy and excellent ankle function based on AOFAS and FADI scores. LEVEL OF EVIDENCE: Prospective cohort study, Level II.

Management of pediatric Madelung's deformity of the forearm due to physeal growth arrest of the distal ulna: a case report.

The authors presented a treatment option for Madelung's deformity due to physeal growth arrest of the distal ulna after Kirschner wire (K-wire) fixation for pediatric forearm fractures. Case presentation: A boy, 16 years old, suffered from a close fracture of the middle third of the left radius and ulna and was treated with open reduction and internal fixation (ORIF) pinning with intramedullary K-wires. Eight months after surgery, the implant was removed. There was no complaint for more than 10 years. Nevertheless, the patient complained of a bowing hand and was diagnosed with Madelung's deformity of the left forearm due to physeal growth arrest 12 years ago. The authors treated this patient with the release of fibrous tissue of the distal ulna, Darrach's procedure, and extensor carpi ulnaris (ECU) tenodesis, along with a close wedge osteotomy of the distal radius and an ORIF of the distal radius. Four months after surgery, the clinical and radiological results were satisfactory. Clinical discussion: Pinning across a physis has the potential to cause full or partial development to stop. Madelung's deformity is usually treated conservatively or surgically, depending on the severity of the symptoms. Darrach's procedure, ECU tenodesis, close wedge osteotomy, and ORIF of the distal radius are available options to treat Madelung's deformity. Conclusion: The use of transphyseal K-wires may result in physeal growth interruption. The developed Madelung's deformity can be satisfactorily managed by Darrach's procedure, ECU tenodesis, in combination with a close wedge osteotomy and ORIF of the distal radius.

Biceps Transfer to FDP-FPL Tendon Augmented with Fascia Lata to Restore Hand Function in Neglected Fracture Treated by Traditional Bone-setters.

Neglected bone fractures owing to the traditional bone-setter practices could lead to devastating complications. We aimed to describe the procedure and outcome of fascia lata augmentation for a forearm massive soft tissue loss case. Here, we report a case of a 14-year-old boy who presented to our hospital with a history of neglected right forearm fracture 4 years prior. He had been treated by a traditional bone-setter instead of seeking professional medical help, which resulted in wide-spread infection requiring debridement and, eventually, massive soft tissue loss, wrist radial deviation deformity due to epiphyseal growth arrest, and loss of all right-hand function. Intervention performed was biceps transfer to flexor digitorum profundus (FDP) and flexor pollicis longus (FPL) tendon augmented with fascia lata with anterior capsulectomy, bilobed flap, and transfixing wire of wrist joint, followed by ulnar centralization with wrist arthrodesis. The patient reported satisfaction postreconstruction, owing to the enhancement of hand function and appearance. He also showed significant improvement in activities of daily living and penmanship, and was even able to continue his old hobby as a traditional puppeteer. Autologous fascia lata tendon transfer connecting biceps to FDP and FPL tendon alongside ulnar centralization with wrist arthrodesis is a novel technique that has promising results to improve hand function and appearance.

Impacts of COVID-19 pandemic on pediatric fractures: a 4-year evaluation of epidemiology and delayed treatment from prepandemic to pandemic period at a tertiary referral hospital.

Background: Definitive fracture surgery should be performed as soon as the patient's condition allows. However, there may be some delays in the treatment during a pandemic. Objective: This study aimed to investigate and compare the epidemiology and delays in pediatric fracture management during the pandemic and prepandemic periods in terms of how many cases were delayed, how long were the delays, and the causes for the delays of fracture treatment. Methods: This comparative-retrospective study was conducted in a tertiary referral hospital in Yogyakarta, Indonesia. The authors included all patients who presented to the hospital from 1 December 2019 to 30 November 2021 (pandemic group period) and from 1 December 2017 to 30 November 2019 (prepandemic group period). The collected data included: patients' age and sex, fractured bone, fracture type, concurrent fracture, hospital stay duration, treatment, need for multidisciplinary treatment, interval from arrival to treatment, and reasons for delayed surgical treatment. The data were obtained from the patients' medical records. Results: Results showed a decrease in the pediatric fracture cases during the 2 years pandemic period compared to the prepandemic period (75 vs. 135 cases). There was no significant difference in the evaluated parameters of demographic, fractured bone and type, hospital stay duration, treatment, other department involvement, and delayed surgical treatment for the fracture. The most common reason for the definitive surgical management delay was the need for medical condition improvements (n=63, 79.7%) and it was significantly associated with the need for multidisciplinary treatment approach (22.83 in isolated orthopedic cases vs. 87.5% in multidisciplinary cases; P=0.000). Conclusion: There was a decrease in the pediatric fracture cases during the 2-year pandemic period compared to the prepandemic period. The delay in definitive surgical management was mainly due to the need for the medical condition improvements and it was associated with the need for a multidisciplinary treatment approach.

Comparison of insertion time, pull-out strength, and screw-media interface area of customized pedicle screw with different core and thread design against commercial pedicle screw: a pilot study on Indonesian Population.

OBJECTIVE: This research aimed to developing customized pedicle screw based on Indonesian vertebral anatomy and compare the insertion time, pull-out strength, and screw-media interface area of different screw design. We have developed 3 different types of pedicle screws (v-thread cylinder-core, square-thread cylinder-core and square-thread conical-core). The thread diameter was calculated from pedicle width of Indonesian population (6 mm). We used commercially available pedicle screw as control group (6.2 mm). RESULT: The insertion time were significantly difference between v-thread cylinder-core pedicle screw (22.94 s) with commercially available pedicle screw (15.86 s) (p < 0.05). The pull-out strength was significantly difference between commercially available pedicle screw (408.60 N) with square-thread conical pedicle screw (836.60 N) (p < 0.05). The square-thread conical-core group have the highest interface area (1486.21 mm2). The data comparison showed that the square-thread conical-core customized pedicle screw group has comparable insertion time and has better pull-out strength than commercially available pedicle screw.

Influence of anthropometric features on peroneus longus graft diameter in Anterior Cruciate Ligament reconstruction: A cohort study.

BACKGROUND: Anterior Cruciate Ligament (ACL) is the most common ligament injury during sports activities that was treated with ACL reconstruction. Nowadays, peroneus longus is used in ACL reconstruction. However, it is difficult to predict the peroneus longus graft diameter for ACL reconstruction. Thus, preoperative measurements are very important to predict peroneus longus autograft for ACL reconstruction. METHODS: A cohort retrospective study was conducted using consecutive sampling method from February 2016 until October 2017 in our center. We recorded patients' characteristics include gender, age, body weight, height, and Body Mass Index (BMI) preoperatively. We measured peroneus longus graft diameter intraoperatively, and analysed data using Spearman correlation. RESULTS: Thirty-nine patients met inclusion criteria. There were 28 males and 11 females in the peroneus group. From the patients' mean characteristics, age was 25.10 ±â€¯9.16, body weight 71.23 ±â€¯14.17, height 169.13 ±â€¯8.81, and BMI 20.96 ±â€¯3.44. Intraoperative peroneus longus diameter measurement was 8.56 ±â€¯0.82. Spearman correlation showed significant correlation between intraoperative peroneus longus diameter with patient's height, body weight, and BMI with p < 0.05. CONCLUSION: Patients' characteristics including gender, height, weight, and BMI in preoperative measurements can predict peoneus longus graft diameter intraoperatively.
