OBJECTIVE: Urinary system injuries may occur iatrogenically during some surgical procedures especially gynecological and obstetrical surgeries. Unfortunately, these injuries can lead to serious complications in patients. In this multicentric study, we aimed to review and report our experiences and results of urinary tract injuries identified during gynecological and obstetrical surgery.
METHODS: We included women with urinary tract injuries during gynecological and obstetrical surgeries between January 2018 and October 2023 at four centers. Detailed data collected include patient demographics, surgical details, injury characteristics, diagnostic and treatment methods, timing of injury diagnosis and management reports of the patients. The incidence of bladder and ureter injuries was evaluated and the rate of intraoperative urological consultations was recorded.
RESULTS: In a total of 328 patients with a median age of 47 years (24-90), urinary tract injuries were diagnosed, including 227 (69.2%) iatrogenic bladder injuries (IBI) and 101 (30.8%) iatrogenic ureteral injuries (IUI). These injuries were diagnosed in 299 patients (91.2%) during surgery and in 29 patients (8.8%) after the surgical procedure. We observed intraoperative detection rates of 71.9% for IBI and 28.1% for IUI. IBI (71.9%) was diagnosed significantly more frequently than IUI (28.1%) (p=0.001). Cesarean section resulted in significantly more frequent IBI, whereas tumor debulking surgeries resulted in more IUI (n=52, 56.5%) than the other types of procedures (p<0.001).
CONCLUSIONS: Our study provides a comprehensive overview of iatrogenic urological injuries during gynecological and obstetrical surgeries. Although the bladder is the most frequently injured organ during gynecological and obstetric surgeries, early diagnosis and urological intervention are mandatory to prevent delayed complications. Surgeons must have a thorough understanding of the pelvic anatomy and appropriate surgical techniques to prevent iatrogenic injuries during surgery and ensure timely diagnosis and treatment of urinary tract injuries.

UNASSIGNED: Paralysis of the trapezius muscle most commonly results from iatrogenic injury to the spinal accessory nerve.
UNASSIGNED: The clinical presentation and physical examination findings of trapezius palsy have been well characterized, but unfortunately the diagnosis of this condition is oftentimes missed or delayed, sometimes leading to unnecessary surgery on the rotator cuff or tendon of the long head of the biceps.
UNASSIGNED: The diagnosis can be confirmed using electromyography with nerve conduction studies. Although nonoperative treatment may help some patients with temporary neurapraxia of the spinal accessory nerve, nerve repair with or without nerve grafting should be performed soon for patients suspected of a nerve transection. Nerve transfers can be considered within the first year after the injury when nerve repair and grafting cannot be completed. For chronic trapezius palsy, transfer of the levator scapulae and rhomboids has been refined and represents a very successful surgical procedure. Rarely, scapulothoracic arthrodesis is considered for individuals with failed tendon transfers or multiple nerve involvement.
UNASSIGNED: Trapezius palsy is oftentimes missed. An accurate diagnosis allows consideration of various treatment modalities that have been reported to provide good outcomes for properly selected patients.

The lingual nerve (LN) is a branch of the mandibular division of the fifth cranial nerve, the trigeminal nerve, arising in the infratemporal fossa. It provides sensory fibers to the mucous membranes of the floor of the mouth, the lingual gingiva, and the anterior two-thirds of the tongue. Although the LN should rarely be encountered during routine and basic oral surgical procedures in daily dental practice, its anatomical location occasionally poses the risk of iatrogenic injury. The purpose of this section is to consider this potential LN injury risk and to educate readers about the anatomy of this nerve and how to treat it.

The lingual nerve (LN) is a branch of the mandibular division of the fifth cranial nerve, the trigeminal. It primarily carries sensory fibers from the lingual gingiva, mucous membranes of the floor of the mouth, sublingual gland, and the anterior two-thirds of the tongue. Recent studies have explored and reclassified the five branches of the LN as branches to the isthmus of the fauces, lingual branches, sublingual nerves, posterior branch to the submandibular ganglion, and branches to the sublingual ganglion. The knowledge of the LN anatomy and its variants is clinically relevant to avoid its injury during oral procedures. The objective of this paper is to review the literature on the LN and to describe the anatomy, its course, and its functions.

UNASSIGNED: Many studies have shown that injury to the popliteus tendon has little consequence for the static stability of the knee following total knee arthroplasty (TKA). However, very few studies have evaluated the effect of intraoperative iatrogenic popliteus tendon injury on the patient-reported outcome measures (PROMs) following TKA. This study aimed to determine the incidence of iatrogenic popliteus tendon injury in our subset of the population and to find out its effect on PROMs.
UNASSIGNED: 100 consecutive osteoarthritic varus knees with flexion deformities less than 20° were operated upon by a single senior experienced arthroplasty surgeon. Patients were assessed intraoperatively for any iatrogenic popliteus tendon injury, the injury site, and the amount of injury which was quantified and graded. PROMs applied for assessment at 1-year follow-up were Knee Society Score (KSS 1), Knee Function Score (KSS 2), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC).
UNASSIGNED: 17% of cases had an iatrogenic popliteus tendon injury. Thirteen had grade II injuries, whereas four had grade III injuries. There was no statistical significance in post-operative knee mobility and PROMs among those with popliteus tendon injury versus non-injured patients.
UNASSIGNED: The incidence of iatrogenic popliteus tendon injury is higher than what we expected. The tendon injury remains a risk, but it is unclear how the popliteus tendon injury will affect patients after the TKA. In our series, such an injury during knee replacement does not affect the functioning of the knee in the short term; however, a long-term follow-up is warranted.

BACKGROUND: Volkmann\'s ischaemic contracture (VIC) is a disabling condition resulting from tissue necrosis due to impaired vascular supply to the limb. Over the years VIC has become rare in developed countries with many different aetiologies described. It was alarming to have high incidence of established VIC in our practice in Nepal. A detailed analysis was conducted to accurately describe this issue.
METHODS: We collected 47 cases of VIC over six years and noted the age, sex, district of origin and cause of VIC, duration of injury to presentation, and the grade of VIC. Then we compared these characteristics of VIC of each Nepal province and created a map to show the problematic regions.
RESULTS: Out of 47 patients, 46 could have been prevented by an early treatment. The most common cause was a tight cast in 25 patients (53.19%), followed by unintentionally self-caused VIC by applying tight bandages in 21 patients (44.68%). Most cases came from province 6 (29.78%). Our group included three mild (6.4%), 35 moderate (74.5%) and nine severe (19.1%) cases of VIC. Only 14 cases (29.78%) had a timely fasciotomy in the past.
CONCLUSIONS: VIC is an irreversible complication of the compartment syndrome which is an easily preventable condition in the setting of developing countries. Our focus should, therefore, aim at preventing such disastrous conditions as 97.87% of cases we encountered could have been avoided by proper primary care. In the case of Nepal most cases came from province 6 and province 3.

This article explores the \'the moment of patient safety\'-the period around 2000 when patient safety became a key policy concern of the British National Health Service (NHS), and other healthcare systems. While harm caused by medical care (iatrogenic injury) had long been acknowledged by clinicians and scientists, from 2000 a new systemic language of patient safety emerged in the NHS that promoted novel managerial and regulatory approaches to patient harm. This language reflected the state\'s increasing role in regulating healthcare, as well as the erosion of medical autonomy and the rise of new forms of bureaucratic management. Acknowledging a transnational, intellectual context behind the rise of policy interest in patient safety-for example, the application of insights from the industrial safety sciences-this article examines the role played by domestic cultural factors, such as medical negligence litigation and healthcare scandals, in helping to define the new language in Britain.

BACKGROUND: During the transtibial posterior cruciate ligament (PCL) reconstruction, drilling depth excessively longer than the tibial tunnel length (TTL) is an important reason to cause popliteal neurovascular bundle injury when preparing the tibial tunnel. This study aims to develop an in-vitro three-dimensional surgical simulation technique to determine the TTL in anteromedial (AM) and anterolateral (AL) approaches.
METHODS: A total of 63 knees\' 3-dimensional (3D) computed tomography models were included in this study. The SuperImage system was used to reconstruct the 3D knee model and locate the tibial PCL site. The established 3D knee model and the coordinates of the tibial PCL site were imported into Rhinoceros 3D modeling software to simulate AM and AL tibial tunnel approaches with different tibial tunnel angles (TTA). The TTL and the tibial tunnel height (TTH) were measured in this study.
RESULTS: In AM and AL tibial tunnel approaches, the TTL showed a strong correlation with the TTA (for AM: r = 0.758, p < 0.001; for AL: r = 0.727, p < 0.001). The best fit equation to calculate the TTL based on the TTA was Y = 1.04X + 14.96 for males in AM approach, Y = 0.93X + 17.76 for males in AL approach, Y = 0.92X + 14.4 for females in AM approach, and Y = 0.94X + 10.5 for females in AL approach.
CONCLUSIONS: Marking the TTL on the guide pin or reamer could help to avoid the drill bit over-penetrated into the popliteal space to damage the neurovascular structure.

Acute limb ischemia (ALI) related to total knee arthroplasty (TKA) is rare. Most occlusions are caused by thrombus formation in the popliteal artery (PA). Currently such cases are revascularized using less invasive approaches such as endovascular therapy or Fogarty thrombectomy. We report a case of ALI in a 65-year-old woman with complete rupture of the PA due to a TKA procedure. She had resting pain and motor paralysis in her right lower extremity after TKA. Contrast-enhanced computed tomography showed occlusion of the right femoropopliteal artery. Subsequently, she was referred to our hospital with a diagnosis of ALI. Initially, a less invasive revascularization procedure was unsuccessfully attempted. Therefore, we performed an emergency distal bypass and succeeded in revascularization. Intraoperative examination revealed a complete rupture of the PA. Postoperatively, the patient exhibited no signs of myonephropathic metabolic syndrome. Although there was significant motor impairment, the affected limbs were successfully salvaged. ALI with complete rupture of the PA associated with TKA has not been reported previously. In cases of iatrogenic ALI after TKA, it would be essential to consider diagnostic and revascularization methods that account for the possibility of severe injury to the PA.
UNASSIGNED: Acute limb ischemia after total knee arthroplasty is a rare and life- and limb-threatening condition. The underlying pathological mechanism is often thrombus occlusion due to mechanical stimuli of the popliteal artery (PA). There are no established treatments for this condition, and less invasive approaches such as endovascular procedures and Fogarty thrombectomy are often used. However, in cases involving severe damage to the PA, bypass surgery may be necessary, and revascularization procedures should be considered accordingly.

BACKGROUND: Intraoperative iatrogenic MCL injuries during primary TKA are rare complications that lack a gold standard management protocol. This review aims to provide insight into various treatment modalities and evidence-based guidance for improved patient outcomes.
METHODS: A comprehensive search across five databases identified relevant randomized control trials and retrospective cohort studies with reported outcomes. A total of 17 studies were included, and variables such as patient demographics, injury type, management, and Knee Society Scores (KSS) were assessed. The quality of included studies was evaluated using the Critical Appraisal Skills Programme tool.
RESULTS: Mean age of included patients ranged from 60.0 to 71.4 years. The mean Body Mass Index ranged from 26.75 to 34.40 kg/m2. Among the included knees, 298 were categorized as MCL avulsion, and 167 as midsubstance/transection injuries. Primary repair with sutures or bone staples emerged as the most common management. Intraoperative MCL injury was correlated with reduced preoperative range of motion (ROM) and postoperative KSS clinical, functional, and pain scores compared to control groups. Postoperative ROM was comparable between MCL injury and control groups, ranging from 100.0° to 130.0° and 107.0° to 130.0°, respectively.
CONCLUSIONS: Current evidence supports primary repair as the preferred management for this complication. Factors such as extent of the tear, type of injury, and the surgeon\'s experience also help to guide treatment. While treatment modalities like allograft or autograft reconstruction show promise, further research with larger sample sizes is needed to enhance future outcomes.
