BACKGROUND: Comminuted fracture of the lower patellar pole has characteristics of both patellar fracture and avulsion of the patellar tendon. Therefore, components of both injury types should be considered during treatment. None of the traditional techniques has proven sufficient alone. Currently described is technique that incorporates principles of osteosynthesis as well as repair of the patellar tendon. METHODS: Total of 23 patients with comminuted fracture of the lower patellar pole were treated surgically and prospectively followed for 24 months...

The Nordic hamstring exercise (NHE) is a field-based exercise designed for knee-flexor eccentric strengthening, aimed at muscle strains prevention. However, possible effects of NHE programmes on other hamstring injury risk factors remain unclear. The purpose of this study was to investigate the effects of a NHE training programme on multiple hamstring injury risk factors. Twenty physically active young adults were allocated into two equal sized groups: control group (CG) and training group (TG). The TG was engaged in a 4-week NHE programme, twice a week, 3 sets of 6-10 repetitions; while CG received no exercise intervention...

Elastic stable intramedullary nailing (ESIN) has been established as state of the art treatment for forearm fractures in children, if operative stabilization is required. Their use has been expanded to single bone shaft fractures, and also more complex injuries such as Monteggia fractures or Monteggia-like lesions. A wide range of complications has been reported in the literature, up to 70% in certain investigations. The purpose of this study was to assess the complication rate after ESIN treatment of forearm fractures in children and adolescents in a representative cohort of patients from a level 1 trauma center in Germany...

The knee is one of the most commonly injured joints in the body. Its superficial anatomy enables diagnosis of the injury through a thorough history and physical examination. Examination techniques for the knee described decades ago are still useful, as are more recently developed tests. Proper use of these techniques requires understanding of the anatomy and biomechanical principles of the knee as well as the pathophysiology of the injuries, including tears to the menisci and extensor mechanism, patellofemoral conditions, and osteochondritis dissecans...

BACKGROUND: Injury rates among professional baseball players may reach as high as 5.8 per 1000 encounters, with pitchers being most vulnerable on account of the excessive biomechanical load on the upper extremity during the throwing motion. Anatomically, the shoulder is the most common site of pitching-related injury, accounting for 30.7% of injuries, closely followed by the elbow at 26.3%. Characteristic valgus loading imparts a predictable constellation of stresses on the joint, including medial tension, lateral compression, and posterior medial shearing...

M D Pinto, A J Blazevich, L L Andersen, P Mil-Homens, R S Pinto
Commonly used injury risk prediction tests such as the hamstring-to-quadriceps (H:Q) strength ratio appear to be poor predictors of non-contact injury. However, these tests are typically performed in a non-fatigued state, despite accumulated fatigue being an important risk factor for both hamstring strain (HS) and anterior cruciate ligament (ACL) injuries in professional soccer players. After the effect of different H:Q calculation methods were compared and contrasted, the influence of neuromuscular fatigue on the H:Q strength ratio and the association between fatigued and non-fatigued ratio scores were examined...

REVIEW
Ian C Sando, Kevin C Chung
The hand is commonly affected in burn injuries. Joints and extensor tendons are vulnerable given their superficial location. Durable coverage that permits relative frictionless tendon gliding and minimizes scar contracture is required to optimize functional outcomes. When soft tissue donor sites are limited, the use of dermal skin substitutes provides stable coverage with minimal scarring, good mobility, and acceptable appearance. A comprehensive review of dermal skin substitutes and their use with burn reconstruction of the hand is provided...

INTRODUCTION: Comprehensive evaluation of movement strategies during functional movement is a difficult undertaking. Because of this challenge, studied movements have been over simplified. Furthermore, evaluating movement strategies at only a discrete time point(s) provide limited insight into how movement strategies may change or adapt in chronic ankle instability (CAI) patients. This study aimed to identify abnormal movement strategies in individuals with a history of ankle sprain injury during a sports maneuver compared to healthy controls...
