Comparative Assessment of the Mechanical Response to Different Screw Dimensions in Scaphoid Fracture Fixation.

The scaphoid is the most commonly fractured carpal bone. Headless compression screws became the gold standard for fixation, but the ideal screw diameter remains debated. This study investigates the relative benefit of using a larger screw diameter to improve stability in typical scaphoid fractures.

The influence of partial union on the mechanical strength of scaphoid fractures: a finite element study.

Assessment of scaphoid fracture union on computed tomography scans is not currently standardized. We investigated the extent of scaphoid waist fracture union required to withstand physiological loads in a finite element model, based on a high-resolution CT scan of a cadaveric forearm. For simulations, the scaphoid waist was partially fused at the radial and ulnar sides.

Comparison of AI-powered 3D automated ultrasound tomography with standard handheld ultrasound for the visualization of the hands-clinical proof of concept.

Objective: To assess the ability of a newly developed AI-powered ultrasound 3D hand scanner to visualize joint structures in healthy hands and detect degenerative changes in cadaveric hands.

Materials And Methods: Twelve individuals (6 males, 6 females, age 43.5 ± 17.

Wrist Arthrolysis: A Systematic Review of Open and Arthroscopic Techniques.

 Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques.  The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness.  A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis.

[Neuropathic Pain - Differential Diagnosis and Treatment from the Hand Surgeon's Perspective].

Neuropathic Pain - Differential Diagnosis and Treatment from the Hand Surgeon's Perspective Neuropathic pain of the wrist and hand can be caused by a multitude of pathologies, such as trauma, iatrogenic damage, local peripheral nerve compression, nerve tumors and systemic diseases. Neuropathic pain can lead to chronification and disability, severely affecting the patients' quality of life and the ability to work. A precise diagnosis is the key to an adequate therapy with satisfactory functional results.

[Tendinopathies - Common Diagnoses in Hand Surgery].

Tendinopathies - Common Diagnoses in Hand Surgery Tendinopathies are among the most frequent reasons for consulting a hand surgeon. The diagnosis can usually be made clinically. A supplementary ultrasound examination helps to visualize the pathology.

[The Painful Wrist].

The Painful Wrist Wrist pain is a problem that can significantly limit patients in their daily activities. The causes are manifold, and treatment is often challenging. A systematic approach is therefore helpful in working up the correct diagnosis.

[Pain In the Thumb and Other Fingers].

Pain In the Thumb and Other Fingers As the population ages, symptoms of osteoarthritis in the hand are seen with increasing frequency. It can lead to substantial pain, physical disability and impair the patient's capacity to work in a population with an increasing retirement age. This article gives an overview about the most prevalent forms of osteoarthritis in the hand, its diagnosis and current treatment options, stressing that the multimodal form of therapy is the most effective.

Editorial Commentary: Fracture Risk After Arthroscopic Osteochondroplasty for Femoroacetabular Impingement-How Can We Become Better?

There is an increased risk of fracture following osteochondroplasty at the femoral head-neck junction for cam-type femoroacetabular impingement. The amount of safe resection has previously been investigated through several biomechanical models, including composite bone, cadaver, animal, and finite element models. Translation of ex vivo results regarding safe resection to an arthroscopic procedure on an actual patient remains a research and clinical challenge.

Surgical correction of kyphotic deformity in a patient with Proteus syndrome.

Background Context: Proteus syndrome (PS) is an extremely rare congenital disorder causing asymmetric overgrowth of different tissues. The etiology remains unclear. Limb deformities are common and often necessitate amputations.

Pelvic incidence-lumbar lordosis mismatch predisposes to adjacent segment disease after lumbar spinal fusion.

Purpose: Several risk factors and causes of adjacent segment disease have been debated; however, no quantitative relationship to spino-pelvic parameters has been established so far. A retrospective case-control study was carried out to investigate spino-pelvic alignment in patients with adjacent segment disease compared to a control group.

Methods: 45 patients (ASDis) were identified that underwent revision surgery for adjacent segment disease after on average 49 months (7-125), 39 patients were selected as control group (CTRL) similar in the distribution of the matching variables, such as age, gender, preoperative degenerative changes, and numbers of segments fused with a mean follow-up of 84 months (61-142) (total n = 84).

Opening wedge osteotomy for distal radius malunion: dorsal or palmar approach?

Background There are various technical variations to consider when performing a corrective osteotomy of a distal radius malunion. We chose two of the more commonly reported techniques and compared the results of volar (palmar) osteotomy and fixation with dorsal osteotomy and fixation. Method Within a continuous cohort of patients who had undergone corrective osteotomy for a malunited Colles fracture, two groups could be identified retrospectively.

Influence of resection geometry on fracture risk in the treatment of femoroacetabular impingement: a finite element study.

Background: A fracture is the most serious complication of surgical resection of the femoral head-neck junction in the treatment of cam-type femoroacetabular impingement (FAI).

Purpose: To investigate the influence of resection length, width, and depth on postoperative fracture risk in activities of daily living.

Study Design: Descriptive laboratory study.
