BACKGROUND: Studies have found that toe-in gait reduced the peak knee adduction moment (KAM) during early stance, while toe-out gait reduced the peak KAM during late stance. However, some other studies found that toe-in or toe-out gait could reduce the KAM throughout stance phase. There is still a divergence of opinion on the use of toe-in or toe-out gait for reducing the KAM. RESEARCH QUESTION: This study aimed to investigate whether static foot posture affected participants' biomechanical responses to three self-selected foot progression angles (FPA): neutral, toe-out and toe-in...

BACKGROUND: Early enteral nutrition (EN) and prone position may both improve the outcome of patients affected by moderate to severe Acute Respiratory Distress Syndrome. Recent guidelines suggest to administer early EN also during prone position. However, EN intolerance, such as high residual gastric volumes, regurgitation or vomiting, may occur during pronation. AIM: This systematic review aims to assess the occurrence of high residual gastric volume, regurgitation or vomiting episodes, that can be encountered in patients receiving EN during prone position...

A posterior tibial tendon (PTT) rupture associated with ankle fractures is a very rare condition. Ankle pronation and external rotation (PER) movement are the typical traumatic mechanism. This injury is frequently overlooked preoperatively. Early diagnosis and treatment are very important to prevent the serious consequences related to functional PTT insufficiency on biomechanics of the foot. Few cases have been described in the literature that highlight the relationship between PTT rupture and PER type ankle fracture with a medial malleolar fracture...

CASE: A 42-year-old man presented with distal radius fracture. We performed external fixation combined with Kirschner wiring, which was removed 6 weeks postoperatively. After the removal of the implants, the patient could not achieve any pronation-supination, and distal radioulnar synostosis became apparent during the follow-up. The patient underwent distal ulnar osteotomy, and 60° pronation and full supination were achieved. No complications were reported at the 32-month follow-up. CONCLUSION: This is a rare case of radioulnar synostosis after percutaneous fixation surgery for distal radius fracture...

Lower-type brachial plexus injuries (BPI) are uncommon, and traditional reconstruction with tendon transfer procedures generally produce mediocre results. However, the advent of nerve transfers has rejuvenated the reconstructive options for peripheral nerve and spinal cord injuries. In this paper, we report the case 32 year-old patient with a C7-T1 avulsion BPI in whom multiple motor and sensory nerve transfers, combined with a free gracilis muscle flap transfer, were used to restore upper-limb functional defects...

INTRODUCTION: Pronation abduction (PA) ankle fractures are often associated with a medial tension failure wound. Though this injury pattern was defined based on the mechanism of injury, there is a paucity of literature evaluating risk factors for understanding which patients will sustain an open PA fracture. Furthermore, how patients with these types of fractures perform relative to other open ankle fractures has not been established. We hypothesized that open PA fractures are associated with obesity and increased number of reoperations...

Recent research indicates that music-supported therapies may offer unique benefits for rehabilitation of motor function after stroke. We designed an adapted guitar and training task aimed to improve coordination between rhythmic and discrete movements because individuals recovering from stroke have greater difficulty performing discrete vs. rhythmic movements. In this paper, we report a feasibility study on training to play this adapted guitar in healthy young adults. Subjects (N = 10) practiced two rhythmic strumming patterns over three consecutive days using their non-dominant hand guided by an audiovisual metronome (60 bpm)...

A variation of the flexor carpi radialis with an excessive muscular bundle was found on the right forearm of a Japanese male cadaver. The flexor carpi radialis had two heads, medial one arising from the medial epicondyle of the humerus, and the other, a variant excessive muscular bundle, arising from the bicipital aponeurosis deep at the medial edge of the tendon of biceps brachii. There was also a muscular slip between the pronator teres and lateral head of flexor carpi radialis. The insertion of the ending tendon of the flexor carpi radialis was also variant, which was not only inserted into the base of the second metacarpal bone, but into the proximal surface of the scaphoid and the tubercle of trapezium...

INTRODUCTION: Total wrist arthrodesis represents a reliable salvage procedure for severe painful conditions of the wrist. To date, wrist arthrodesis using a dorsal plate reaching from the distal radius to the third metacarpal is still recommended. A new implant (APTUS© 2.5 TriLock Wrist Fusion Plate, Medartis Suisse) that does not cross the third carpometacarpal joint (CMCJ-3) has been introduced recently. The purpose of this retrospective study was to compare both implants concerning early functional and clinical results...

BACKGROUND: Early application of prolonged prone positioning has been shown to improve patient survival in moderate to severe adult respiratory distress syndrome (ARDS) patients. Prone position is a key component of lung protective mechanical ventilation in association with low tidal volume and neuromuscular blocking agents in patients with severe ARDS. Pressure sores are the major prone position complication. The rate of complication is lowering with the increase in center expertise...

PURPOSE: Fractures of distal radius are one of the common orthopaedic injuries. Placing the plate on volar surface requires release of underlying pronator quadratus (PQ) muscle. No consensus is present in the literature about the repair or not of the PQ. The purpose of this study was to evaluate the influence of PQ repair on functional outcome and complications. METHODS: Retrospectively 83 patients of distal radius fractures managed with volar plating between 2014 and 2016 were evaluated...

PURPOSE: Distal radius fractures are common fractures of the upper extremity. Whereas surgical outcomes have been extensively investigated, the impact of risk factors such as body mass index (BMI) and smoking on patient outcomes has not been explored. We hypothesized that obesity and smoking would have a negative impact on the functional and radiographic outcomes of surgically treated patients with distal radius fractures. METHODS: We performed a retrospective analysis of patients surgically treated for a distal radius fracture between 2006 and 2017 at 2 level 1 trauma centers...
