Osteochondroma of Distal End Radius Presenting as Carpal Tunnel Syndrome: A Case Report.

Introduction: Osteochondromas are the most common benign bone tumors, typically occurring during growth. However, their occurrence in the distal radius is rare, and presentation with carpal tunnel syndrome (CTS) symptoms in pediatric patients is even rarer.

Case Report: Here, we describe a unique case of an 8-year-old female who presented with CTS symptoms and was simultaneously diagnosed with an osteochondroma of the distal radius.

The Impact of De-Roofing of Lateral Calcaneal wall in Open Reduction and Internal Fixation of Intra-Articular Fractures: Clinico-Radiological Outcomes of a Novel Technique and Review of Literature.

Background: Most displaced intra-articular calcaneus fractures need to be treated surgically but postoperative soft tissue complications limit to achieve of optimal functional outcomes. Certain mini-invasive techniques lead to better soft tissue healing but anatomical reduction gets compromised.

Objectives: We aim to evaluate the results of lateral wall de-roofing of the calcaneum to achieve good anatomical reduction as well as to minimise soft tissue complications in the internal fixation of calcaneal fractures.

Medial tibial bone resorption following total knee arthroplasty comparing a traditional with a kinematic design.

Background: New total knee prostheses are being designed to improve clinical outcome, survivorship and patient satisfaction following total knee arthroplasty (TKA). A new knee system was developed with improvements in patellofemoral joint, trochlear geometry, polyethylene formulation and tibial baseplate. Aim of this study was to compare the newer kinematic knee system with its existing predecessor knee system in terms of clinical outcome, revision rates, radiographic outcomes specifically medial tibial bone resorption.

Clinical and Surgical Insights on Bilateral Total Knee Arthroplasty in Ochronotic Arthropathy: A Case-based Review.

Introduction: Ochronotic arthropathy (OcA) is a consequence of alkaptonuria, a rare systemic-inherited metabolic disorder leading to accumulation of homogentisic acid in articular cartilage and subsequent early degeneration of the joints. Only few cases of OcA managed with bilateral total knee arthroplasty (TKA) has been described in the literature so far. We aim to discuss surgical pearls, pitfalls, and clinical outcome of OcA of knees managed with simultaneous bilateral TKA.

"Floating Hip" and "Floating Knee" Associated with Hip Dislocation, Sciatic Nerve Palsy, and Patella Fracture: A Case Report.

Case: We report a very rare case of simultaneous ipsilateral floating hip and floating knee (SIFHFK) injury with the neck of the femur and patella fracture and hip dislocation associated with sciatic nerve injury in a 45-year-old man after a road traffic accident. We adopted a staged approach for surgical fixation of the fractures after stabilization. At the latest 2 years follow-up, the patient was asymptomatic with satisfactory clinical outcome.

Analysis of clinical and radiological outcomes of long tibial stemmed total knee arthroplasty in knee osteoarthritis complicated by tibial stress fracture.

Objective: Knee arthritis associated with tibial stress fractures represents an uncommon and difficult clinical scenario to treat. The use of long, fluted tibial extension rods has been vital in the management of such cases owing to immediate fracture stability and single-stage surgery without the need to open the fracture site. This study investigates clinical and radiological outcomes following total knee arthroplasty using a tibial extension stem in cases of knee osteoarthritis with tibial stress fracture.

A three-dimensional gadolinium organic framework based on a pyridinedicarboxylic acid organic linker with a paddle-wheel-type network structure.

A new gadolinium(III)-pyridine-2,5-dicarboxylic acid (Gd-2,5-Hpdc)-based three-dimensional coordination polymer, namely, poly[dimethylazanium [bis(μ-pyridine-2,5-dicarboxylato)gadolinium(III)]], {[(CH)NH][Gd(CHNO)]}, CP-1, has been synthesized via a typical solvothermal method. The as-synthesized material was characterized in the solid state using single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and FT-IR spectroscopy. During the synthesis of CP-1, the in situ dimethylformamide (DMF) promotes the formation of a dimeric unit and these act as secondary building blocks in the assembly of a three-dimensional anionic {[Gd(pdc)]} framework.

The application of low-dose dexamethasone in total knee arthroplasty: finding out the best route and dosage schedule.

Background: The use of dexamethasone as additive to multimodal analgesic regimen in total knee arthroplasty has been well established, but the most suitable route, effectiveness, safety and dose schedule of low-dose dexamethasone is not known.

Methods: We conducted a prospective, randomized, double-blinded trial to investigate and compare the analgesic and antiemetic effects and safety of low-dose (8 mg) dexamethasone introduced as periarticular injection or intravenous (as a single dose or in two divided doses of 4 mg separated by 24 h) in unilateral total knee arthroplasty patients.

Results: The single dose intravenous administration as well as the periarticular administration of dexamethasone had similar mean visual analogue scores which were significantly lower than divided dose group at 24 and 48 h postoperatively.

Disassembly of Components of a Monoblock Bipolar Hip Prosthesis Following Dislocation: A Case Report and Review on "Bottle Opener Effect".

Introduction: Bipolar hemiarthroplasty has been reliable and successful treatment for geriatric patients following neck of femur fractures. Dissociation/disassembly of bipolar prosthesis is a rare complication in which separation of outer head from inner head leads to failure of prosthesis and needs revision surgery. The disassembly though commonly seen after years of primary surgery as a result of polyethylene wear leading to fixed varus position of outer head but it can happen in an acute setting anytime in immediate or late post-operative period following posterior dislocation with closed reduction attempt.

Calcaneal osteomyelitis caused by Acremonium sp in an immunocompetent adult - A case report.

Fungal osteomyelitis of calcaneus is rare in immunocompetent adults. A case of fungal osteomyelitis of calcaneus in a 19 year old immunocompetent female without any history of trauma caused by Acremonium sp is presented. The patient was treated with surgical debridement, autogenous iliac crest bone grafting and antifungal chemotherapy for 6 months.

Clinical, Functional, and Midterm Survival Analysis on Sigma Curved Plus Ultracongruent Polyethylene Insert in Primary Total Knee Arthroplasty: A Retrospective Study.

Background: Posterior-stabilized (PS) total knee arthroplasty (TKA) poses problems such as the need for intercondylar notch bone resection as well as cam and post wear and patella clunk. Owing to its heightened anterior profile, an ultracongruent polyethylene insert prevents the excessive posterior translation of tibia in the case of a deficient or scarified posterior cruciate ligament (PCL). This study aimed to determine whether an ultracongruent insert provides satisfactory clinical and functional outcomes and midterm survival benefits.

Stress Fracture of Isolated Middle Cuneiform Bone in a Trainee Physician: A Case Report and Review.

Stress fractures are chronic fatigue failure of bone from repetitive subthreshold loads. Insufficiency fractures occur in bones that are already osteopenic and fail to withstand normal loads over time. Stress fractures of cuneiform bones are extremely rare and usually reported to happen in athletes or recruits.
