Introduction: Carpal tunnel syndrome (CTS) is the most commonly encountered neuropathy. The entrapment of the median nerve at the wrist can be corrected with a carpal tunnel release (CTR) procedure. The objective of this retrospective study was to determine the demographic, medical, and surgical characteristics of the patients with CTS who presented for CTR surgery in a tertiary hospital in Malaysia. Materials and Methods: Malaysians patients with CTS who had undergone a CTR during the period from 1st June 2017 to 31st December 2017 were enrolled into the study. Each patient had a minimum follow-up of three months. The demographic data of age, gender, race and occupation, and the comorbid illnesses and associated risk factors were recorded. The prevalence and occurrence of CTS in the dominant or non-dominant hand and the effectiveness of surgical intervention were also noted. Data was collected, analysed and stored in Microsoft Excel and SPSS 25. Results: There was a total of 76 cases of CTR surgeries done in 62 patients in the study. Eighty percent of the patients were female, and most of the patients belonged to the age group of 41-60 years. Malays constituted 74.2% of the patients, and 34% were housewives. Hypertension, dyslipidaemia and diabetes mellitus were the three major comorbidities. Cervical spondylosis was seen in one-fourth of the patients. Bilateral hand involvement was present in 54.8% of patients. 59.7% of CTR surgery was done on the dominant hand alone, 17.7 % CTR on the non-dominant hand alone and 22.6% CTR on both hands. Numbness and pain (50%) were the predominant presenting symptoms. The most positive signs were the Durkan test (77.6%), followed by the Tinel sign at the carpal tunnel and the Phalen's test. At follow-up, three months or more, after the surgery, 75% of the patients showed a satisfactory improvement. Conclusion: Patients, who had undergone CTR, had a higher prevalence of pre-morbid conditions, and a quarter of them presented with associated cervical spondylosis. The most common presentation was a combination of numbness and pain. Many obtained satisfactory improvement post-surgery and thus open surgery could be considered a reliable treatment for CTS.

Kaposi hemangioendothelioma (KHE) is a rare vascular neoplasm that presents usually within the first year of life. Because of its rarity and complexity, there is often a delay in diagnosis. KHE could be associated with a life-threatening consumptive coagulopathy named the Kasabach-Merritt phenomenon (KMP). Here, we present the case of a 2-month-old girl who presented with progressive redness and swelling of her right upper limb over 6 weeks. Multiple health practitioners misdiagnosed her condition as an insect bite, cellulitis, and necrotizing fasciitis and gave treatment accordingly, which proved futile. A full blood count revealed bicytopenia of anemia and thrombocytopenia, a normal coagulation cascade, low fibrinogen, and raised D-Dimer levels. The imaging was suggestive of a high-flow vascular tumor likely to be a KHE. Subsequently, she was started on single-agent oral sirolimus with a dose increment to achieve satisfactory therapeutic levels and was treated for 1 year. She successfully completed the treatment regimen and had only transient hypertriglyceridemia, which resolved upon the completion of treatment. Currently, she is in remission 3 years after treatment. Keeping her case as an example, we would like to highlight the potentially lethal misdiagnosis of KHE with KMP, the importance of an early diagnosis of this condition, and the successful treatment outcome with single-agent sirolimus.

PURPOSE: This study evaluated the clinical and biochemical safety profile of infiltration of lidocaine with adrenaline in wide-awake local anesthesia no tourniquet for distal radius plating.
METHODS: Twenty-four participants were randomly assigned to the therapeutic group (n = 19) (1% lidocaine in 1:100,000 adrenaline) and control group (n = 5) (2% lidocaine alone). Clinical parameters, including skin necrosis, duration of recovery of sensation, and lidocaine toxicity, were monitored. The serum lidocaine level was measured at different time intervals using a high-performance liquid chromatography reagent.
RESULTS: No lidocaine toxicity was recorded in any participant. The therapeutic group had a longer time for recovery of sensation. There was a significant difference in the serum lidocaine levels between both the groups at all time intervals up to 6 hours, with all participants exhibiting serum lidocaine levels below the mild toxicity level of 6.0 μg/mL.
CONCLUSIONS: Lidocaine used within a safe recommended dose in wide-awake local anesthesia no tourniquet for distal radius plating is clinically and biochemically safe.
CLINICAL RELEVANCE: Determining the clinical and biochemical safety profile of lidocaine with adrenaline in wide-awake local anesthesia no tourniquet can promote wider use of this technique.

PURPOSE: Fixation of metacarpal or phalanx bone fractures is usually performed under general anesthesia (GA) or regional anesthesia and with the use of a tourniquet to minimize bleeding. However, the use of tourniquet causes pain and discomfort after surgery. Wide-awake local anesthesia no tourniquet (WALANT) enables the surgery to be performed with the patient fully awake and without a tourniquet, which allows intraoperative assessment of function during surgery. This study aims to compare the perioperative parameters and clinical outcomes between GA versus WALANT in hand fracture fixations.
METHODS: Forty-eight patients with hand fractures were recruited over a period of 15 months. Twenty-one patients had undergone fracture fixation under GA, whereas another 27 patients had the surgery under WALANT. Parameters including vital signs (heart rate and systolic blood pressure), surgery duration, estimated blood loss, visual analog scale, and quick disabilities of the arm, shoulder, and hand (QuickDASH) questionnaire were evaluated.
RESULTS: Wide-awake local anesthesia no tourniquet group had significantly higher systolic blood pressure values and higher estimated blood less than GA group. Wide-awake local anesthesia no tourniquet group also documented shorter surgical time compared with GA group, but the difference was not significant. In terms of clinical outcomes, WALANT group recorded significantly lower visual analog scale score at 2 hours and 2 weeks postsurgery. However, WALANT has a comparable QuickDASH score with GA group except at 3 months postsurgery.
CONCLUSIONS: Wide-awake local anesthesia no tourniquet surgery for hand fracture fixation provides a similar analgesic effect and comparable QuickDASH score except at 3 months postsurgery compared with GA.

INTRODUCTION: Carpal Tunnel Syndrome is known to be a common complication during pregnancy especially during the third trimester.

AIM: This article focuses on its impact to the third trimester pregnant mothers with CTS.

METHODS: Third trimester pregnant mothers with no other known risk factors for CTS, were interviewed and examined for a clinical diagnosis of CTS. The severity of CTS was assessed by means of symptoms severity and functionality using the Boston Carpal Tunnel Questionnaire.

RESULTS: Out of 333 third trimester pregnant mothers, 82 (24.6%) were clinically diagnosed with CTS. Malay race was found to have significant correlation with the diagnosis of CTS (p = 0.024) and are two times more likely to get CTS during pregnancy (OR = 2.26) compare to the non-Malays. Bilateral CTS was two times higher (n = 58, 63.4%) than unilateral cases (n = 30, 36.6%), however no significant correlation between the two was found with severity (p = 0.284) or functional (p = 0.906). The commonest complaint was numbness/tingling during day time (n = 63, 76.8%). Majority of the CTS cases were mild (n = 66, 80.5%) and approximately one third (n = 28, 34.1%) had affected hand functions. All symptoms related to pain was found to have significant correlation with severity (p = 0.00, OR = 12.23) and function (p = 0.005, OR = 5.01), whereas numbness and tingling does not (Severity, p = 0.843, function, p = 0.632).

CONCLUSION: This study shows that even though CTS in third trimester pregnancy is prevalent, generally it would be mild. However, function can still be affected especially if patients complain of pain.

INTRODUCTION: Distal end radius fractures are common fractures commonly treated with an option of open reduction and plating. Traditionally, plating is performed under general anesthesia (GA) or regional block. Recently, a new technique of plating under wide-awake local anesthesia with no tourniquet (WALANT) has been introduced. We aim to compare the preoperative anxiety level, intraoperative pain scores, post-operative pain scores, operating time, blood loss and clinical outcome of distal end radius plating with WALANT versus GA with tourniquet.
METHODS: We conducted a randomized controlled study on patients with closed fracture of the distal end of the radius requiring open reduction and plating from January 2019 till April 2020. We recruited 65 patients (33 patients in the WALANT group and 32 patients in the GA group). Randomization was done via block randomization. Data were collected to evaluate preoperative anxiety using the Amsterdam Preoperative Anxiety and Information Scale (APAIS) score, intraoperative pain score during injection (baseline) (V1), 10 minutes after injection (V2), during incision (V3), during gentle manipulation (V4), during aggressive manipulation (V5) and during first drilling of screw (V6), blood loss, duration of surgery and post-operative pain score. Additionally, intraoperative visual analog scale (VAS) score was obtained in the WALANT group. At three weeks, six weeks, three months and six months after operation, the Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores and range of motion (ROM) of the wrists were obtained.
RESULTS: The average age in the WALANT group was 47.19 (range, 36-64) years and GA group was 49.48 (range, 38-60) years. The mean APAIS score obtained was 7.78 (WALANT group) and 7.36 (GA group) with no statistical difference. For intraoperative VAS, only during V4 and V5 were the scores 1/10; otherwise at all other phases, the VAS score was 0. The average time for surgery was statistically longer in the WALANT group (61.22 minutes) compared to the GA group (55.33 minutes) (p = 0.003). There was no statistical difference in mean blood loss in both groups. The average post-operative VAS showed statistical significance only at 1 hour and 12 hours post-operation with no statistical difference at 2 and 24 hours post-operation. There was no difference in the post-operative ROM including wrist flexion, extension, supination and pronation for both groups up to six months' follow-up.
CONCLUSION: There was no statistically significant difference in terms of preoperative anxiety level, intraoperative and post-operative VAS score, amount of blood loss and clinical outcome in both groups for plating of the distal end radius. However, the operating time was slightly longer in the WALANT group. We conclude that distal radius plating under WALANT has similar outcomes to GA. In centres with limited resources, WALANT offers a safe, reliable and cheaper option, reserving GA time for head, abdominal and thoracic surgery.

Background The Wide-Awake-Local-Anaesthesia-No-Tourniquet (WALANT) technique achieves an almost bloodless field for clear visualization during surgeries. WALANT utilizes lidocaine and epinephrine for anesthesia and hemostasis, respectively, without the usage of sedation and tourniquet. This avoids the potential side effects of tourniquet-related pain and sedation-related complications. However, acceptance is still low due to concerns regarding the safety of epinephrine injection in the finger. There is a persistent belief that epinephrine can cause digital ischemia. Purpose To evaluate retrospectively possible complications of hand surgeries performed using the WALANT technique. Methods All finger and hand procedures performed under the WALANT technique from June 2016 to May 2021 in an urban tertiary hospital were studied retrospectively. Results There were a total of 1073 cases, of which 694 were females and 379 were males. The mean age was 55 years. Finger surgeries (e.g., trigger finger release, excision of finger lesions, removal of implants) consisted of 707 cases; and the rest (366 cases) were hand surgeries (e.g., carpal tunnel release, excision of hand lesions, removal of implants). In all cases reviewed, there were no instances of circulatory compromise. There were also no circumstances where usage of reversal with phentolamine is recorded. Conclusion We believe that performing finger and hand surgeries using the WALANT technique is safe and beneficial. The usage of WALANT in hand surgeries avoids tourniquet pain. However, WALANT should be used with caution in those with vascular insufficiency or disease.

Background: Congenital infantile fibrosarcoma (CIF) is a rare malignant soft tissue tumor that predominantly occurs in children under 1 year of age. CIF is frequently misdiagnosed with other conditions like hemangioma of infancy, infantile fibromatosis, or kaposiform hemangioendothelioma. Disseminated intravascular coagulopathy (DIVC) is rarely reported to be associated with CIF. Case presentation: We describe an infant who presented with a large mass over the right arm. She was initially treated conservatively as hemangioma but was later confirmed by tissue histopathological examination to have CIF as the mass rapidly increased in size. She developed massive intra-tumoral bleed with DIVC whilst receiving neoadjuvant chemotherapy requiring multiple blood products transfusion. An urgent near-total resection of the tumor was performed in view of life threatening bleeding despite multiple blood transfusions. Post-operatively, she received further adjuvant chemotherapy. Subsequently, she remained in complete remission 32 months off-treatment and has full function of the affected limb. Conclusions: CIF is an important condition to be considered in infant who has large mass over the extremity. DIVC could be associated with large CIF and when it occurs can be life-threatening. Whenever feasible early surgery should be performed in very young patients with large CIF to prevent mortality from bleeding.
