This document outlines the surgical approaches, pearls, pitfalls, and complications for proximal interphalangeal joint (PIPJ) surgery. It discusses the volar, dorsal, and lateral approaches. The volar approach is useful for implant arthroplasty, open reduction and internal fixation, and corrective osteotomies. The dorsal approach traditionally damages the extensor tendon but can be modified. The lateral approach provides access while partially releasing surrounding structures. Complications include extensor lag, poor range of motion, and disturbance to surrounding tissues. Careful surgical technique and anatomic preservation are emphasized.

Management concept - Delayed management
Splints, casts and traction
Definite surgery delayed for 10 -14 days
Prolonged bed rest and hospital stay
Damage control surgery
Decubitus ulcer
Disuse atrophy
Early definitely stabilization long bone fracture reduced incidence of fat embolism syndrome
Early Total Care
Damage control surgery
Usually within the first 24hrs
Early Total Care - Advantages
Early fixation favors skin and soft tissue healing
Prevent ongoing tissue damage
Pain relief
Improve joint function
Early mobilization
Respiratory distress
Pneumonia
Early stabilisation of hemodynamically unstable or/and had concomitant chest or head injury patients develop high mortality
mainly by ARDS and MODs
Reasons for the high mortality ?
Two hit phenomena
These findings indicated that
ETC is not appropriate for unstable poly trauma patients
Damage control surgery
Damage control is a new term first used by the US Navy during World War II to describe emergency measures for control of flooding that threatens to sink a ship.
Goal is to ensure survival of the ship until it reaches a port where definitive repairs can be safely performed.
Basic strategies of DCO -
Control of haemorrhage
Damage control surgery
Minimize the second hit
Immediate and rapid stabilization of long bone fractures - EF
Release of tight soft tissue compartments
Reductions of dislocations
Surgical debridement of open wounds
Amputation, in cases of unsalvageable extremities
Definitive fixation is later
Immediate external fixation followed by early closed intramedullary nailing is a safe treatment method for fractures of the shaft of the femur in selected polytrauma patients.
Which patient need DCO approach ?
Patients who have sustained orthopedic trauma have been divided into four groups:
Damage control surgery
Patient categorization
Limitations of DCO
Axial skeleton and femoral fractures
No external fixation
Even ex fix , patient mobilization is poor - bed ridden condition
Anatomical reduction favours pain relief, soft tissue healing and muscle function
Limitations of DCO
Classification of patient condition is not static, dynamic and changed with resuscitation
DCO recommended for those patients who are unstable or in extremis however the optimal time and type of treatment, who are in border line remain controversial
arthroscopy of the knee joint is a relatively common orthopedic procedure to treat a host of sports injuries and other knee diseases. Commonly a 4 mm size scope is used via two standard arthroscopy portals. Arthroscopic examination of the knee confirms MRI findings. Synovial fluid and biopsy can be taken to confirm diagnosis.

The hip joint is a ball and socket joint consisting of the femoral head and acetabulum. This articulation provides multiple planes of movement and is highly congruent. Articular cartilage, consisting of type II collagen, covers the majority of the femoral head. The acetabulum peripherally consists of articular cartilage while the central floor is non-articular and filled with a fatty layer termed the pulvinar. The ligamentum teres arises from both the transverse acetabular ligament and the central non-articular layer of the acetabulum and attaches to the central femoral head. It may play a role in stabilizing the hip joint.

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
