Outcomes of the Treatment of Humeral Shaft Fractures by Closed Reduction and Internal Fixation With Multiple Intramedullary Kirschner Wires (K-wires)

Background Humeral shaft fractures are common orthopedic injuries, and their treatment options vary based on fracture characteristics. One surgical method involves closed reduction and internal fixation (CRIF) with multiple intramedullary (IM) Kirschner wires (K-wires), which remains less explored, especially in adults. This study aims to investigate the outcomes of the treatment of humeral shaft fractures by closed reduction and internal fixation with multiple flexible intramedullary K-wires. Materials and methods We conducted a retrospective study at King Abdulaziz Medical City, Riyadh, Saudi Arabia, focusing on patients with traumatic humeral shaft fractures who underwent flexible intramedullary K-wire fixation. We analyzed nine patient records for demographic information, fracture location, type, mechanism of injury, intra-operative and post-operative factors, and complications. Results Fractures mostly affected the middle third of the humerus (55.6%) and were primarily transverse or oblique (77.8%). Motor vehicle accidents were the leading cause of injury (66.7%). Intra-operative time was 125 minutes on average, with minimal blood loss (78 mL). No participants required intra-operative blood transfusion. Complications following IM K-wire fixation were absent in all cases. Three patients had not yet undergone instrumental removal, and most reported mild or no pain during the final follow-up. All participants achieved a full range of motion for their elbows. All participants achieved complete radiological and clinical union (healing) of their fractures. Conclusion The use of multiple intramedullary K-wires for the treatment of humeral shaft fractures in this study demonstrated positive outcomes with low complication rates. This approach provides an effective option for managing these fractures, particularly in cases where surgical indications favor it.

How Ready are Pediatricians and Family Physicians in Saudi Arabia to Perform Clinical Screening of Developmental Dysplasia of the Hip?

Background

Developmental dysplasia of the hip (DDH) is one of the most common hip pathologies in pediatric age group and late diagnosis remains a major concern in Saudi Arabia.

Objective

The aim of this study is to examine the ability of Saudi Arabian pediatricians and family physicians to conduct clinical screening for (DDH) by estimating their clinical knowledge and skills and analyzing the gaps therein to determine whether there is potential to launch a national screening protocol for DDH in Saudi Arabia.

Methods

This is a multicenter cross-sectional study from three major regions in Saudi Arabia (Central, Eastern and Western provinces). The assessed aspects are risk factors, age of screening, incidence in Saudi Arabia, physical signs and diagnostic markers, and treatment, along with their 'clinical knowledge and skills' score.

Results

Half of the participants were pediatricians, while the rest were family physicians. More than a third of the participants were considered to have adequate knowledge, ie, above the mean score. Dimensions with the most significant knowledge gaps included the incidence of DDH in Saudi Arabia, adverse effects of swaddling, and the management of a high-risk infants presenting with a negative physical examination. Additionally, there were relatively low rates of awareness regarding positive risk factors as well as a generally poor ability to identify physical signs. Clinical knowledge and skill levels were significantly lower among family physicians.

Conclusion

Pediatricians and family physicians in Saudi Arabia still need further training to improve their clinical skills for DDH screening. The proper administration of training programs could eventually enable the gradual implementation of a national systematic screening program.

Effect of type of disease-modifying antirheumatic drugs on depression and anxiety of patients with rheumatoid arthritis in Saudi Arabia: a cross-sectional study

Background

Rheumatoid arthritis (RA) can cause depression and anxiety. This study evaluated the factors associated with depression and anxiety in patients with RA and examined the effect of conventional and biologic disease-modifying antirheumatic drugs (DMARDs).

Methods

This cross-sectional study was conducted in a regional hospital in Riyadh between March and November 2022 and included 213 patients with RA. Depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS) and data about patients' DMARDs use was obtained from the hospital's medical records.

Results

Based on the HADS scores, 35 (16.4%) and 49 (23%) patients with RA had depression and anxiety, respectively. There was a significant association between the level of depression and anxiety and the use of leflunomide and tocilizumab among patients with RA (p = 0.006 and p = 0.009, respectively). Patients with RA who took leflunomide had significantly higher scores for anxiety (β = 0.158, value of p = 0.037) when compared to patients who did not take leflunomide. Patients with RA who took etanercept showed a significantly lower depression score even after adjusting for confounders, including sociodemographic, clinical, and lifestyle factors (β = -0.189, p = 0.043).

Conclusion

The present study highlighted the prevalence of psychiatric disorders among patients with RA and the level of depression and anxiety may differ between patients with RA depending on the type of DMARDs used. We recommend patients with RA be screened regularly for depression and anxiety to avoid further extra-articular systemic complications associated with RA.

Aggressive L3 vertebral hemangioma coexisting with adult thoracolumbar scoliosis: Case report

Vertebral hemangiomas are benign vascular tumors that are commonly asymptomatic. A low percentage might become aggressive; however, they are not known to be associated with scoliosis. We present a case of a third lumbar vertebral lesion coexisting with a moderate thoracolumbar scoliosis. The patient's initial presentation was back pain with bilateral lower limb radiculopathy and neurogenic claudication. Diagnosis was established using CT and MRI, which showed classical findings of an aggressive vertebral hemangioma. The patient underwent Partial hemangioma excision and scoliosis correction, with satisfactory outcome at 1 year follow up.

Thoracic cystic schwannoma: case report and review of literature

INTRODUCTION

Schwannomas are the second most common type of intra-dural lesions involving the thoracic spine. They are frequently seen as solid and heterogeneous lesions. Totally cystic thoracic schwannomas represent a rare pathological schwannoma variant, with only four cases reported in the English literature to our knowledge.

CASE PRESENTATION

We report an 80-year-old male who presented with upper back pain for 3 months. Magnetic resonance imaging (MRI) showed a cystic lesion at the level of T6-T7 with peripheral contrast enhancement. The lesion was removed in total surgically with complete resolution of the patient's symptoms.

DISCUSSION

The diagnosis of cystic schwannomas is often delayed due to the paucity of symptoms and the lack of meticulous investigation. The presence of rim enhancement on contrast-enhanced MRI may be the only clue for the diagnosis. It is important to consider cystic schwannomas in the differential diagnosis of cystic spinal lesions since the best surgical outcome is strongly related to earlier diagnosis and total resection of the lesion.
