The extensive peat bogs of Southern Scandinavia have yielded rich Mesolithic archaeological assemblages, with one of the most iconic artefacts being the bone point. Although great in number they remain understudied. Here we present a combined investigation of the typology, protein-based species composition, and absolute chronology of Maglemosian bone points. The majority of the bone points are made from cervids and bovines. However, changes both in species composition and barb morphology can be directly linked to a paucity of finds lasting nearly 600 years in Southern Scandinavia around 10,300 cal BP. We hypothesize that this hiatus was climate-driven and forced hunter-gatherers to abandon the lakes. Furthermore, the marked change in bone points coincides with a change in lithic technology. We, therefore, propose that the Maglemose culture in Southern Scandinavia is fundamentally divided into an Early Complex and a Late Complex.

Introduction: Patients with chronic low back pain face functional, psychological, social and professional difficulties. Multidisciplinary Rehabilitation Programs (MRP) can be an effective treatment to help these patients to improve their condition and return to work.
Objective: To determine baseline predictors for return to work after an MRP for patients with chronic low back pain struggling to maintain their job.
Evaluating optic system compression in sellar tumors: A novel application of quantitative pupillometry.
Acta Neurochir (Wien)

Medical Faculty of Heidelberg University, Heidelberg, Germany.
Introduction: Tumorous growths in the sellar region pose significant clinical challenges due to their proximity to critical visual structures such as the optic chiasm and optic nerves. Given their proximity to the optic system, these tumors are often diagnosed due to a progressive decrease in visual acuity. Thus, surgical intervention is crucial to prevent irreversible damage, as timely decompression can halt the progression of edema and subsequent optic atrophy.

This study proposes a method for assessing the transverse toughness of human long-bone cortical tissue. The method is based on a three-point bending test of pre-notched femur diaphysis segments, post-processed using the compliance method coupled with numerical simulations. Given the cracking nature of bone and if cracking processes remain confined to the crack tip, it is assumed that the compliance method can be used.

Department of Orthopedics and Trauma Surgery, Ospedale Civile Maggiore Di Borgo Trento, University of Verona, Piazzale Aristide Stefani, 1, 37126, Verona, VR, Italy.
Purpose: The main objective of this prospective study was to assess clinical, radiographic and safety mid-term outcomes after THA with a short cemented stem in an elderly patient cohort. Moreover, the study aimed at investigating the mid-term survivorship of the implant and the incidence of complications.
Methods: 96 consecutive patients (100 cases) underwent THA with a short cemented stem.
A modified Radiographic Union Score for Tibia (RUST) scoring system for patella fractures treated with osteosynthesis shows excellent intra und interobserver reliability.

Introduction: Patellar fractures are rare at 1% incidence of all fractures. However, they can cause significant functional impairments due to the patella's role in knee joint extension. Current scoring systems lack objectivity in assessing patellar healing.
