An All-Arthroscopic Technique of Repairing Foveal Tears of the Triangular Fibrocartilage Complex Using a Bone Anchor-Repair Made Simple.

Traumatic foveal tears of the triangular fibrocartilage complex lead to ulnar-sided wrist pain and instability, resulting in painful motion and loss of grip strength with a severe impact on the overall function of the upper limb. Surgical repair is nothing new and has traversed through the realm of open repair to arthroscopic assisted to all arthroscopic repair techniques over the many decades, with arthroscopic repairs showing better visualization, lesser trauma, and equally favorable patient outcomes. Techniques had varied from using trans osseous tunnels to bone anchors, with or without the usage of special jigs. Here, we describe a simple and fast 3 portal arthroscopic technique of repairing the torn foveal insertion of the triangular fibrocartilage complex using a bone anchor inserted under arthroscopic and fluoroscopic guidance into the fovea. Both the dorsal and volar limbs of the triangular fibrocartilage complex are repaired arthroscopically, resulting in a strong anatomic repair resulting in a stable and pain-free wrist.

An All-arthroscopic Technique of Repair of Substance Tears of the Triangular Fibrocartilage Complex in Symptomatic Patients.

Substance tears of the triangular fibrocartilage complex (TFCC) can occur secondary to trauma of the wrist. On the dorsal periphery, they are considered Palmer 1B tears or Atzei class 1 tears. If along the radial side, they can manifest as a tear of the central disc, classified as a Palmar class 1A tear. If it involves the ligaments, it is stated as a pre-1D tear as per the new classification system by Luchetti and colleagues. Multiple excellent repair techniques exist in the current literature for dorsal peripheral tears and even for those in the substance of the TFCC, whereas there are successful evolving techniques of repair of avulsed tears and those involving the substance of the ligaments on the radial side adjacent to the sigmoid notch. Here, we describe our technique of repairing substance tears of the TFCC arthroscopically without the need for any specialized equipment apart from the basic arthroscopy set. The technique was conducted in a patient with a transverse substance tear on the radial side of the triangular fibrocartilage involving the central disc with complete resolution of symptoms. It is a simple technique, which can be used to repair class 1B peripheral tears and pre-1D tears in the substance of the TFCC.

Surgical Management of Peripheral Vein Thrombophlebitis in the Upper Extremity.

Purpose: Peripheral vein thrombophlebitis has a reported overall incidence ranging from 20% to 80%. Thrombophlebitis can progress despite antibiotic therapy to become a challenging clinical problem requiring surgical intervention. There is currently no consensus on its optimal management. We reviewed our experience of surgical intervention with analyses of the indications for intervention, descriptions of the surgical procedures, and outcomes. We aimed to provide guidance on the management of this potentially serious complication. Methods: This is a retrospective review of 51 patients with thrombophlebitis refractory to conservative management between January 2017 and August 2020. Results: Analyses revealed a high prevalence of comorbidities, including diabetes mellitus, malignancy, and chronic kidney disease. A total of 60% of patients had concurrent bacteremia, and the decision to operate had a low threshold in the presence of these factors. On exploration, 80% of patients had intraluminal thrombus, 47% had intraluminal pus, and 29% had pus beyond the veins or extending proximally. The surgical approach employed in 98% of patients involved an extensile incision in those with several morbidity factors (diabetes mellitus, chronic kidney disease, or bacteremia). One patient presented with severe clinical signs of local infection, and on exploration, there was intraluminal pus and thrombus up to 10 cm. A novel technique of a minimally invasive approach of intermittent stab incisions was employed in a young and healthy patient without comorbidities. Conclusions: We developed an algorithm to guide the indications for intervention and surgical approach to thrombophlebitis. The threshold for intervening surgically should be lowered by the presence of comorbidities. The failure of antibiotics to resolve the clinical signs of infection or the suspicion of abscess formation should mandate intervention. Thrombosed sections of the vein should be ligated proximally and distally and excised and surrounding collections of pus drained. Delayed secondary wound closure is usual. Stab incisions may limit surgical dissection and subsequent scarring in less severe cases. Type of study/level of evidence: Prognostic IV.

A Technique of Continuous Catheter Irrigation in an Infected Wrist Joint: Improving Management in Septic Arthritis of the Wrist.

Septic arthritis of the wrist though decidedly rare can lead to severe consequences with loss of form and function of the hand. The approach to diagnosis and treatment remains challenging and may need multiple surgeries, prolonged hospital stays along with intravenous antibiotics for restitution of a pain and disease-free functioning wrist. Arthroscopic washout of the wrist joint, has paved the way for a less invasive and more effective approach to the management of the condition reducing the number of operations needed and the need for open wrist washout. In our paper, we describe in addition to arthroscopic washout of an infected wrist joint the insertion of irrigation catheters followed by continuous irrigation with normal saline through the catheters using an infusion pump for 5 days leading to resolution of symptoms without further surgical interventions.

Hand Surgery in Singapore.

Singapore as an island nation is one of three countries in the world that has hand and reconstructive microsurgery (HRM) as an independent specialty. The 52 accredited hand surgeons serving a population of 5.7 million facilitate hassle free access to patients. Hand surgery historically is rooted very much in orthopaedic surgery as in most Asian countries with more than five decades of rapid evolution. Singapore pioneered a structured and systematic training program for HRM and the local surgeons have contributed significantly to the body of knowledge in hand surgery with targeted research and publications with three surgeons being awarded international recognition for their contributions. Singapore continues to contribute significantly to surgical volunteerism regionally through active involvement in the training of regional surgeons through their sustainable volunteer activities and through international fellowships in Singapore hospitals. The future of hand surgery in Singapore will be more competency and multidiscipline based on community-centered approach.

Peripheral Vein Thrombophlebitis in the Upper Extremity: A Systematic Review of a Frequent and Important Problem.

BACKGROUND: The acceptable incidence of thrombophlebitis following intravenous cannulation is 5%, as recommended by the Intravenous Nurses Society guidelines, but publications have reported startling figures of 20% to 80%. Given the frequency of intravenous lines, this presents a potential clinical problem. We aimed to determine the predisposing patient, catheter, and health care-related factors of peripheral vein thrombophlebitis in the upper extremity. METHODS: In this systematic review, we used a comprehensive search strategy to identify risk factors of thrombophlebitis from inception to May 20, 2019. Studies reporting risk factors of peripheral vein thrombophlebitis of adult patients admitted to the hospital and receiving an intravenous cannulation were included. The Quality of Prognostic Studies tool was used in the assessment for risk of bias to determine the study quality. RESULTS: Of the 6910 studies initially identified, 25 were eligible for inclusion. Qualitative syntheses revealed that patient-related factors that confer a higher risk included intercurrent illness, immunocompromised state, comorbidities such as diabetes mellitus, malignancy, previous thrombophlebitis, burns, and higher hemoglobin levels. Catheter-related risk factors included catheter size, duration, and site of insertion. Intravenous antibiotics and potassium chloride predisposed to thrombophlebitis. Cannulation by an intravenous therapy team and more nursing care were associated with a decreased risk. A P-value < .5 was considered to be statistically significant. CONCLUSION: Recognition of the predisposing factors would allow for targeted strategies to aid in the prevention of this iatrogenic infection, which may include closer monitoring of patients who are identified to be vulnerable. Based on this systematic review, we developed an algorithm to guide clinical management. Further research is warranted to validate this algorithm.

Acute ulnar nerve compression associated with pisiform fracture - a case report and literature review.

We evaluated a case of pisiform fracture with ulnar nerve compression managed with pisiformectomy. At 11 months' follow-up, the patient regained range of motion of the wrist and grip strength with no subjective loss of function and normal nerve conduction study. We compared other treatment modalities and reviewed their outcomes.

Minimally Invasive Palmaris Longus Abductorplasty for Severe Carpal Tunnel Syndrome.

Camitz abductorplasty is the most commonly used tendon transfer in patients with severe carpal tunnel syndrome with significant muscle wasting and loss of opposition. This procedure requires a long incision in the palm to harvest a strip of palmar aponeurosis to lengthen the palmaris longus tendon, allowing it to reach the abductor pollicis brevis insertion. Several complications have been attributed to this extensive dissection in the palm. We describe a minimally invasive palmaris longus abductorplasty using a strip of free flexor carpi radialis tendon graft to achieve the necessary length. This can be done together with carpal tunnel release in patients with severe carpal tunnel syndrome.

Wrist Septic Arthritis: An 11 Year Review.

BACKGROUND: This report utilizes 11 years (2003-2013) of clinical records of patients for a retrospective evaluation of the effectiveness of various combinations of diagnostic methods, treatment options and surgical procedures to try to determine the optimal combinations to improve the rate of success for the treatment of septic wrist arthritis. METHODS: Analysis of records of 40 patients treated for septic wrist arthritis in our hospital involving records of physical examination, full blood analysis, biochemical, microbial profiles, type of surgical intervention, length of stay, number of surgical interventions to resolution and the rate of morbidity and mortality. The patients were subdivided into 2 groups, consisting of 6 (mortality) in one group and 34 (non-mortality) in the other. The various parameters as listed above were compared for differences. The patient records included those from immunocompromised elderly patients, with other existing medical complications such as gout, pseudogout, cellulitis and arthritic flare that made accurate diagnosis of septic wrist arthritis challenging. RESULTS: There is a trend showing better success in the treatment of septic wrist arthritis among patients without co-morbid medical problems. Due to the unavoidable delays in microbial identification, it was noted that escalation of antibiotics should be adopted especially for the immunocompromised patients. CONCLUSIONS: Staphylococcus aureus, the most common microbial pathogen in our findings, point to the need to adopt a lower threshold for escalation of antibiotics for immunocompromised patients with slow reversal of infection in order to reduce morbidity, mortality, number of surgeries and length of post-operative stay.

Escalators, rubber clogs, and severe foot injuries in children.

BACKGROUND: Reports in the media suggest that escalator-related foot injuries are on the rise. Trendy, bright-colored rubber clogs have been implicated in a significant number of these incidents involving children. We review the children who sustained severe foot injuries on escalators, were wearing rubber clogs at the time of injury, and who were admitted to hospital for emergency surgery. METHODS: A list of children who sustained foot injuries on escalators was generated from the hospital database and included for study. From clinical chart review, demographic data, footwear type, and injuries sustained were recorded. Inpatient or outpatient treatment rendered was also recorded for each patient. RESULTS: Between September 2006 and September 2008, we treated 17 children for escalator-related foot injuries. There were 10 boys and 7 girls who were between 2 and 9 years of age (mean: 5.5). Thirteen children (76.5%) from this group were wearing rubber clogs at the time of injury. Nine of these 13 (69.2%) children sustained severe foot injuries that required admission to hospital for emergency surgery and are the focus of this study. One child had an unsalvageable traumatic amputation of the great toe at the level of the interphalangeal joint. Two children sustained crush injuries to the great toe: 1 with severe degloving and the other with an open fracture of the proximal phalanx. One child had an open fracture-dislocation of the second metatarsophalangeal joint with a comminuted fracture of the second metatarsal. Five children sustained multiple deep lacerations in the foot and 2 of them had associated cut tendons that required repair. In the group not wearing rubber clogs, 3 of 4 children had severe foot injuries. In this series, 4 children with rubber clogs and another child with a different footwear sustained minor injuries; they were treated as outpatients. CONCLUSIONS: Escalator-related foot injuries involving rubber clogs can result in severe crushing of the foot and even traumatic amputation. The broad toe-box design may give a false perception of the distance between the foot and the side of the escalator, whereas the 'softness' of these rubber clogs makes them vulnerable to crush by moving escalator steps. This is the first report in the literature describing escalator-related severe foot injuries in children who were wearing rubber clogs. Injuries sustained can be significant and permanent. The potential dangers of escalators and rubber clogs must not be underestimated. LEVEL OF EVIDENCE: Level IV, Case Series.
