Scaphoid fracturesw
Scaphoid fractures are the most common carpal bone fractures, often occurring in young adults from falls on an outstretched hand. The scaphoid has a tenuous blood supply and is prone to non-union, especially for proximal pole fractures. Treatment depends on fracture type and stability, ranging from casting to operative fixation with screws. Complications include malunion, delayed union, non-union and avascular necrosis, requiring further procedures like bone grafting or carpal fusion.
Scc
Squamous cell carcinoma (SCC) is the second most common skin cancer. It has a propensity to metastasize, making it responsible for most skin cancer deaths. Risk factors include UV exposure, age, immunosuppression, and primary dermatoses. Histological subtypes include pleomorphic, adenoid, small cell, verrucous, and keratoacanthoma. Tumor size greater than 2 cm and depth greater than 6 mm increase metastatic risk. Treatment involves surgical excision with adequate margins or other modalities like radiation for high risk cases.
Hand tumoursw
The document discusses common hand tumours such as ganglion, giant cell tumour of tendon sheath, and epidermoid inclusion cysts. It provides details on clinical presentation, investigations, classification systems, and treatment approaches for various bone and soft tissue tumours that can occur in the hand. Common malignant tumours of the hand discussed include synovial sarcoma, clear cell sarcoma, chondrosarcoma, and osteosarcoma.
Carpal tunnel
Carpal tunnel syndrome is caused by compression of the median nerve as it passes through the carpal tunnel. While open carpal tunnel release was previously the standard treatment, endoscopic carpal tunnel release has gained popularity as an alternative. Multiple reviews have found no difference in symptom relief between the two techniques. Evidence is conflicting on whether endoscopic surgery results in earlier return to work. Endoscopic surgery is associated with a higher risk of reversible median nerve injury but results in superior grip strength and less scar tenderness in the short term. Further research is still needed to make definitive conclusions about the relative effectiveness of open versus endoscopic carpal tunnel release.

Basal cell carcinoma is a malignant skin tumor caused by chronic sun exposure. It is most common in areas with high sun exposure like the head and neck. While typically slow-growing and non-metastatic, it can cause local tissue destruction if left untreated. Treatment options include surgical excision, Mohs micrographic surgery, cryotherapy, and topical chemotherapy. The goal of treatment is complete removal of the tumor while preserving skin and function.
Hand anatom yw
The document summarizes the anatomy of the hand, including:
1) The skin, fascia, muscles, blood vessels, and nerves of the palm and dorsum. Key structures include the thenar and hypothenar muscles innervated by the median and ulnar nerves respectively.
2) The flexor tendons in the hand pass through zones in the flexor sheath and connect to the phalanges via pulleys.
3) Extensor tendons are separated into compartments by the extensor retinaculum and pass dorsally to extend the fingers.
4) Interossei muscles abduct and adduct the fingers at the MCP and PIP joints.
Flaps in the hand
The document discusses various local flap options for reconstructing fingertip injuries. It describes the anatomy of the fingertip and goals of reconstruction which are to close wounds, maximize sensation, preserve length and function. Local flap options mentioned include volar V-Y flaps, bilateral V-Y flaps, cross-finger flaps, thenar flaps and lateral island flaps. Choice of flap depends on wound orientation and configuration.
Pipjw
This document discusses the anatomy and injuries of the proximal interphalangeal joint (PIPJ). The PIPJ is stabilized by articular contours, ligaments including the collateral and volar plate ligaments, and adjacent tendons. Dorsal dislocations of the PIPJ can be classified as Type I-III depending on the degree of ligament disruption and presence of fractures. Treatment depends on whether the injury is open or closed, stable or unstable, and may involve splinting, traction, pinning, open reduction and internal fixation, or tenodesis. Complications can include redisplacement, angular deformity, contractures, and stiffness.

Body contouring
A 48-year-old man who lost 200 kg through diet and exercise underwent a lower body lift. During the 4-hour, 2-surgeon procedure, he required repositioning 3 times and 6 drains. Post-operatively he developed hemorrhages requiring exploration. He was discharged after 8 days requiring weekly drainage of seromas. The document discusses nutritional deficiencies common after bariatric surgery that can impact wound healing for body contouring procedures. It notes diet and exercise patients have higher complication rates than those who had bariatric surgery. Careful patient evaluation and counseling is important due to the risks and limitations of massive weight loss body contouring.
G ps suture workshop
The document provides guidance on suturing techniques. It recommends everting the skin edges when suturing to achieve better dermal apposition, improved healing, and a finer scar. A triangular suture passage with the base located deeply is suggested to evert the wound edges, while an inverted triangular shape tends to invert them. Dermal sutures are recommended first to reduce tension before cutaneous sutures. Adjusting where the knot lies can help flatten steps between uneven wound edges. The document also reviews appropriate suture materials for different areas, recommending absorbable sutures that elicit minimal tissue reaction for the face and longer-absorbing sutures for prone areas like the back.
Evidence based medicine and cosmetic surgery
This document discusses the relationship between evidence-based medicine and aesthetic plastic surgery. It provides definitions of evidence-based medicine and outlines its five primary components. The document then examines several examples of how evidence-based medicine has been applied to topics in aesthetic plastic surgery, including bariatric surgery outcomes, breast augmentation practices like antibiotic use and drain usage, and outcomes of facelifts with or without drain usage. It acknowledges that while plastic surgery literature often contains lower levels of evidence, the field should aim to both appreciate existing evidence and continue raising the overall level of evidence to best serve patients.
Lower limb flapsw
This document describes the arterial blood supply and potential flaps in the lower limb. It discusses various fasciocutaneous and musculocutaneous flaps that can be raised based on named arteries in the lower limb, including the femoral, lateral circumflex femoral, profunda femoris, popliteal, and posterior tibial arteries. Specific flaps are described such as the anteromedial thigh flap, gracilis flap, and gastrocnemius flap. The angiosome concept and variations in vascular anatomy are also covered.
Mucous cysts dip jw
Mucous cysts of the DIPJ usually occur in older adults and are associated with osteoarthritis. They contain mucin and form from degeneration of joint structures. Clinically, they appear as nodules near the DIPJ that can cause nail deformities. Treatment involves surgical excision, sometimes with additional procedures like osteophyte removal. Complications include residual deformities, stiffness, skin issues, and recurrence due to incomplete excision or persistent arthritis.
Eyelid recon
This document describes the anatomy and reconstruction of the eyelids. It discusses:
1. The layers and structures of the eyelid including the skin, orbicularis oculi muscle, tarsal plates, levator palpebrae superioris muscle, and conjunctiva.
2. Embryology, blood supply, innervation, and cross section of the eyelid.
3. Specific structures like the orbital septum, tarsal plates, pre-aponeurotic fat, and lacrimal system.
4. Goals and requirements of eyelid reconstruction including reestablishing function, protection, cosmesis as well as anterior and posterior lamellae reconstruction techniques.
Burns
The document discusses emergency management of burns. It provides information on common causes of burns, pathophysiology involving initial and secondary tissue damage, burn wound classification models, and initial management steps of EMSB (airway, breathing, circulation, disability, exposure, fluids). It also covers assessment of burn severity and extent, wound care, fluid resuscitation guidelines, signs necessitating escharotomy or burn unit transfer, and the evolving nature of burn wounds over time.
Radial nerve anatomyw
The radial nerve originates from cervical and thoracic nerve roots and is the largest branch of the brachial plexus. It provides cutaneous innervation to the posterior arm and forearm and motor innervation to triceps, brachioradialis, and extensor muscles of the forearm and hand. The radial nerve is vulnerable to compression at the radial tunnel as it travels through the forearm. Compression can cause radial tunnel syndrome. The superficial branch of the radial nerve can be affected by Wartenberg syndrome. Radial nerve palsy can result from fractures, injuries, tumors, or iatrogenic causes.
Skin graftsw
This document discusses the physiology and process of skin grafts. It describes the layers of skin - epidermis and dermis - and their functions. It explains the classification of different types of skin grafts including full thickness and split thickness grafts. The document then outlines the four phases of "take" that a skin graft undergoes as it revascularizes and attaches to the recipient bed. It provides details on the histological and structural changes that occur in the epidermis and dermis during the healing process over subsequent days and weeks. Factors that influence graft survival and potential causes of graft failure are also summarized.
Annual scientific congress perth coupler
This document discusses the venous coupler as an alternative to sutures for microvascular anastomoses. It provides a brief history of vascular couplers and summarizes previous animal and clinical studies showing couplers can create anastomoses faster than sutures with similar or better patency rates. A study at Imperial College London directly compared the time and costs of using couplers versus sutures for venous anastomoses, finding couplers were significantly faster, saved over 12 minutes of ischemia time per case, and were cost effective after accounting for equipment and material costs.
Fellowship talk moradi
Akademikliniken (AK) is a plastic surgery clinic in Stockholm with two centers and over 100 employees. They offer a 1-year unpaid fellowship that provides housing and meals. Starting this year, the fellowship will be formalized into a paid 1-year program. The fellow would assist with over 4,500 operations per year, primarily aesthetic procedures. In Moradi's 4.5 month fellowship, he assisted with over 300 cases across facial aesthetics, breast procedures, body contouring surgeries, and free flaps. The clinic also hosts monthly masterclasses and social events for fellows and surgeons.
Anatomy ulnar nerve
This document discusses Cubital Tunnel Syndrome and Ulnar Tunnel Syndrome. Cubital Tunnel Syndrome involves compression of the ulnar nerve at the elbow, and can cause sensory changes and weakness in the hand. It is often treated initially with splinting and anti-inflammatories, and may require surgical decompression or transposition of the nerve. Ulnar Tunnel Syndrome (Guyon's canal) involves compression in the wrist and can cause numbness and weakness, sometimes from conditions like ganglions or fractures; its treatment may involve surgical release of the canal.
Nsw speech path talk flapvs grafts
Flaps and grafts are used in reconstructive surgery to restore form and function. A flap maintains its blood supply, and can be skin, muscle, bone or composite tissue. Key differences between flaps and grafts are discussed. Various flap types are described based on their components, relationship to the defect, blood supply nature, and movement. Reconstructive goals include separating cavities, protecting structures, obtaining wound healing, restoring function and aesthetics. Specific flap choices are outlined for pharyngeal and mandibular defects, facial reanimation, and tongue reconstruction.
Principles of tendon transfersw
This document discusses principles of tendon transfers. Tendon transfers involve reattaching a functioning tendon to replace a paralyzed or injured tendon. Key points include indications such as nerve injuries or ruptured tendons. Donor tendons should match the amplitude, power, and function needed. Timing depends on factors like prognosis. Post-operative rehabilitation is important to regain motion and train new muscle functions. The goal is to restore useful hand function rather than just motion.
Zplasty
Z-plasty is a surgical technique used to close wounds where two triangular flaps based on a shared limb are transposed to close each other's defects, increasing the length of scars. The degree of elongation depends on the angle of the flaps, with greater angles providing more lengthening up to 125% for 90 degree flaps. Multiple opposing or adjacent Z-plasties can be combined for even greater lengthening effect.
Annual scientific congress perth siea vs diep
The document discusses a study comparing abdominal drain volumes and seroma rates between SIEA (superficial inferior epigastric artery) flaps and DIEP (deep inferior epigastric perforator) flaps for breast reconstruction. The study found that SIEA flaps had significantly higher abdominal drain volumes than DIEP flaps, though length of hospital stay was only increased by about 1 day. SIEA flaps also showed a non-significant trend toward higher rates of outpatient seroma aspiration. While SIEA flaps are less invasive than DIEP flaps, this study suggests they may be associated with increased abdominal seroma rates post-operatively.
G ps flexor tendon talk
This document discusses flexor tendon zones, tenosynovitis (infection of the flexor tendon sheath), and its diagnosis and treatment. Tenosynovitis most often results from penetrating trauma near joint creases. It causes purulence and adhesions within the sheath, destroying gliding and blood supply. Key signs are tenderness over the sheath, swelling of the digit, and pain with passive extension. Early cases may be treated with antibiotics but established infections require prompt surgical drainage to prevent tendon and skin necrosis.
Nsw speech path talk flapvs grafts
Flaps and grafts are used in reconstructive surgery to restore form and function. A flap maintains its blood supply, while a graft does not. There are several types of flaps characterized by their tissue components and blood supply. Free flaps use tissue transferred without a pedicle, while pedicled flaps maintain an attachment. Reconstructive procedures aim to separate cavities, restore function, and provide aesthetically pleasing results with minimal complications. Specific flap choices are tailored to the goals and defects in pharyngeal, mandibular, facial, and tongue reconstruction.
Economic viability of_autologous_breast_reconstruction_final
This document summarizes the results of a retrospective audit assessing the financial implications of breast reconstruction procedures. It analyzed 274 patients who underwent 278 primary breast reconstructions and 366 secondary procedures between 2000-2007. DIEP flap reconstruction had the longest average length of stay but also the highest costs. Implant reconstruction had fewer secondary procedures on average but costs were still substantial due to additional procedures needed. The document concludes that while autologous reconstruction provides better long-term symmetry, the current tariff system financially discourages immediate and bilateral breast reconstruction procedures.

Acquired Anterior Thoracic Lung Herniation and Repair: A Rare Case and Discus...W. Thomas McClellan, MD FACS
This case report describes a rare case of an acquired anterior thoracic lung herniation in a 63-year-old female that developed four years after video-assisted thoracic surgery (VATS) for lung cancer resection and adjuvant radiation for breast cancer. The 8 cm x 10 cm chest wall defect was reconstructed with mesh and reinforced with a latissimus dorsi flap. The authors believe the herniation was caused by intercostal muscle denervation from the distant VATS and soft tissue damage from radiation. The patient had complete resolution of symptoms after surgical repair. The case demonstrates that lung herniation can occur remotely from VATS incision sites due to potential nerve or muscle injury during the procedure.Intro to-plastics
Plastic and reconstructive surgery aims to restore form and function through surgical techniques. The key areas covered are anatomy of skin circulation via perforators, angiosomes, and vascular territories; skin physiology and function; and the reconstructive ladder of closure techniques from primary closure to grafts and flaps. Flaps maintain an intrinsic blood supply unlike skin grafts.
Carpal tunnel
Carpal tunnel syndrome is caused by compression of the median nerve as it passes through the carpal tunnel. While open carpal tunnel release has traditionally been used to treat carpal tunnel syndrome, endoscopic carpal tunnel release is an alternative technique. Reviews of randomized controlled trials have found no clear difference in relief of symptoms between the two techniques. The evidence is conflicting on whether endoscopic carpal tunnel release results in earlier return to work compared to open release. Endoscopic release may provide superior short-term grip strength and less scar tenderness but risks more reversible median nerve injuries. Further research is still needed to make definitive conclusions.

Swan neck deformityw
Swan neck deformity is characterized by hyperextension of the proximal interphalangeal (PIP) joint and flexion of the distal interphalangeal (DIP) joint. It results from intrinsic tightness and extensor tendon imbalance caused by rheumatoid arthritis (RA). Management involves preventing further PIP hyperextension, restoring DIP extension, and addressing any underlying joint problems or soft tissue tightness based on the classification and pathophysiology. Surgical options range from splinting to tendon procedures to joint replacement depending on the severity of deformity and functional impairment.
Radial nerve palsy tendon transfersw
This document discusses tendon transfers, which involve detaching the tendon of a functioning muscle and reattaching it to replace the function of a paralyzed muscle. The key points are:
1. Tendon transfers work to correct issues like instability, imbalance, lack of coordination, and restore function.
2. They are indicated for paralyzed muscles due to nerve injury, neurological disease, or nerve repair with early transfer. They are also used for injured tendons or muscles.
3. General principles include only restoring functional hand motion, considering patient factors, ensuring the recipient site is suitable, matching the donor muscle properties, and immobilizing initially to reduce tension.
Perineal reconstruction
Perineal reconstruction after pelvic surgery aims to restore form and function through flap reconstruction. The VRAM flap provides reliable vascularity, bulk, and a large skin paddle, making it the first choice for reconstruction. A study found VRAM flaps had significantly fewer complications than thigh flaps for perineal defects. Other flap options include the gracilis, posterior thigh, and perforator flaps from the gluteal arteries. Proper postoperative care is needed to ensure flap survival.
Parotid glandw
The document discusses the anatomy and tumours of the parotid gland. It describes the location and lobes of the parotid gland, its blood supply and innervation. It then discusses the various types of tumours that can occur in the parotid gland and other salivary glands, including pleomorphic adenoma, Warthin's tumour, mucoepidermoid carcinoma, adenoid cystic carcinoma, and metastatic carcinomas. It provides details on the histology, presentation and characteristics of these tumour types.
Orbital fracturesw
Orbital fractures involve breaks in the bones surrounding the eye socket. The orbital anatomy consists of 7 bones that form the pyramid-shaped orbit. Common types of orbital fractures include fractures of the orbital floor, medial wall, and lateral wall. Signs and symptoms vary depending on the structures involved but may include diplopia, limited eye movement, numbness, and vision changes. Evaluation involves history, exam of cranial nerves and eye movement, and CT scan. Treatment depends on findings but may involve initial management with ice and antibiotics followed by surgery to repair the fracture if indicated to address issues like diplopia or enophthalmos. Surgical approaches and potential complications are discussed.
Lower limb flapsw
This document describes the arterial blood supply to the lower limbs and various flap options based on these arteries. It outlines the vascular anatomy of arteries like the femoral artery and its branches, including the lateral circumflex femoral artery. It then provides details on specific musculocutaneous and fasciocutaneous flap options based on these arteries, such as the anteromedial thigh flap, anterolateral thigh flap, gracilis flap, and hamstring flaps.
Hand infections
Hand infections were a major cause of disability before antibiotics. Kanavel defined hand anatomy and drainage techniques. Penicillin reduced severe infections. Antibiotics alone rarely cure infections beyond 48 hours due to vessel thrombosis and pressure in closed spaces. Felons and paronychia each account for 1/3 of hand infections and usually result from minor trauma introducing Staph aureus. Flexor tenosynovitis is a surgical emergency to prevent tendon damage. Deep space infections involve the palmar, dorsal, thenar and midpalmar spaces and spread if not drained properly.
Jejunum asc presentation
1. The authors present their 10-year experience with 43 jejunal free flaps for reconstruction following pharyngolaryngectomy.
2. They report a 100% acute flap survival rate and an overall benign fistula rate of 4.7%. No fistulas occurred in patients who received a prophylactic pectoralis major muscle flap after radiotherapy.
3. Using a gastrointestinal stapler for the proximal and distal anastomoses was associated with a lower fistula rate compared to hand-sewn anastomoses.
Flap classification
This document discusses different methods of classifying flaps used in reconstructive surgery. It describes classification based on composition, proximity to the defect, method of movement, and vascular anatomy. Specific types of flaps are also outlined including local, regional, distant, and free flaps as well as fascio/cutaneous and musculocutaneous flaps. Arterial supply, types of movement including advancement, transposition, and rotation are summarized.
Fingertip recon
This document discusses reconstructive options for fingertip injuries. The goals of reconstruction are to close wounds, maximize sensory return, preserve length and joint function, and obtain a cosmetic appearance. Options include healing by secondary intention, skin grafting, and local flap reconstruction using flaps such as volar V-Y flaps, bilateral V-Y flaps, cross-finger flaps, and thenar flaps. Major complications are hypersensitivity and cold intolerance, which usually resolve after 1-2 years.
