[Purpose] The purpose of this study was to investigate adapting wheelchair cushions to hemiplegic individuals based on trunk function and a single-leg driving motion. [Subjects and Methods] Subjects were 18 hemiplegic adults who were able to use and sit up in a wheelchair. Subjects were grouped into Able and Unable groups according to the Functional Assessment for Control of the Trunk (FACT). The posterior pelvic tilt angle and the driving speed and muscle activity at the long head of the biceps femoris at the start of wheelchair use were measured for three wheelchair cushion conditions, and FACT factors and cushion factors were then analyzed...

INTRODUCTION: Major anatomical textbooks generally state that the biceps brachii muscle (BB) is composed of long and short heads, whereas the brachialis muscle (BR) consists of a single head. However, the numbers of heads comprising the BB and the BR are very variable. The purpose of this study was to investigate how the branching patterns of the musculocutaneous nerve (MC) influence the number of heads of the BB and the BR. MATERIALS AND METHODS: Morphological examinations of the BB and MC were conducted using cadavers of 22 Japanese individuals, and morphological examinations of the BR and the MC were conducted in 9 of those 22 individuals...

A rotator cuff tear is a common injury in athletes and workers who repeatedly perform overhead movements, and it is not uncommon for this demographic to return to activity shortly after treatment. A biceps tenotomy is often performed in the presence of a rotator cuff tear to help reduce pain and improve joint function. However, the effect of this procedure on the surrounding tissues in the glenohumeral joint is unknown. Therefore, the purpose of this study was to investigate the effect of a biceps tenotomy in the presence of a supraspinatus rotator cuff tear followed by overuse activity on ambulatory function and mechanical and histologic properties of the remaining rotator cuff tendons and glenoid cartilage...

Hamstring (HS) muscle injuries are the most common injury in sports. They are correlated to long rehabilitations and have a great tendency to recur. The HS consist of the long head of the biceps femoris, semitendinosus, and semimembranosus. The patient's clinical presentation depends on the characteristics of the lesion, which may vary from strain to avulsions of the proximal insertion. The most recognized risk factor is a previous injury. Magnetic resonance imaging is the method of choice for the injury diagnosis and classification...

This study aimed to investigate activation characteristics of the biceps femoris long head (BFlh) and semitendinosus (ST) muscles during the acceleration and maximum-speed phases of sprinting. Lower-extremity kinematics and electromyographic (EMG) activities of the BFlh and ST muscles were examined during the acceleration sprint and maximum-speed sprint in 13 male sprinters during an overground sprinting. Differences in hamstring activation during each divided phases and in the hip and knee joint angles and torques at each time point of the sprinting gait cycle were determined between two sprints...

BACKGROUND: Massive rotator cuff tears (MRCT) can be treated arthroscopically by partial reconstruction, tenotomy/tenodesis of the long head of the biceps, and debridement. A new treatment option is the additional implantation of a biodegradable spacer (InSpace Balloon®; ISB) into the subacromial space, which reduces subacromial shear forces to keep the humeral head centered in the glenoid. The aim of this study is to investigate the clinical outcome of patients with MRCT who were treated arthroscopically with or without an additional ISB...

The long head of the biceps (LHB) tendon is a potential generator of pain within the shoulder. Tenodesis of the LHB is a treatment option for several pathologic shoulder conditions. We conducted a study to determine trends in LHB tenodesis at a subspecialty-focused shoulder orthopedic practice. We hypothesized that the rate of LHB tenodesis would increase significantly over time and that there would be no significant change in the age of patients who underwent LHB tenodesis. Records of 4 fellowship-trained sports or shoulder/elbow orthopedic surgeons were used to identify total number of common arthroscopic shoulder surgeries performed between 2004 and 2014...

INTRODUCTION: Massive rotator cuff tears (RCTs) in the context of shoulder dislocations are relatively uncommon in the young adult (<40 years) and if reported are more commonly described in association with acute traumatic anterior glenohumeral dislocations. They have rarely been described with posterior dislocations, regardless of patient age. This is the 1(st) case reported in the context of posterior dislocations, where a triad of biceps tendon rupture, posterior dislocation, and RCTs was observed during surgery...

BACKGROUND: Pathologies of the long head of biceps tendon (LHB) can cause anterior shoulder pain. Surgical treatment includes tenotomy and tenodesis (TD), however TD causes fewer cosmetic deformities and less cramping of the biceps muscle. To date, numerous techniques for TD have been described but the "gold standard" has not yet been established. OBJECTIVES: The purpose of this study is to evaluate the functional and cosmetic outcome following subpectoral biceps TD with an interference screw and a cortical-button (STLHB-IC) after 1 year...

BACKGROUND: Injury to the distal musculotendinous T junction (DMTJ) of the biceps femoris is a distinct clinical entity that behaves differently from other hamstring injuries due to its complex, multicomponent anatomy and dual innervation. Injury in this region demonstrates a particularly high rate of recurrence, even with prolonged rehabilitation times. PURPOSE: To describe the anatomy of the DMTJ of the biceps femoris and analyze the injury patterns seen on magnetic resonance imaging (MRI) to aid prognosis and rehabilitation and minimize the risk of recurrence...

Proximal humerus fracture after subpectoral tenodesis (SPBT) of the long head of the biceps tendon is a rare but serious complication. Examination of the biceps tendon diameter after preparation for SPBT in vivo suggests that the use of a smaller tenodesis screw is technically possible. However, questions remain about the biomechanical strength of the tenodesis construct with a smaller interference screw and about whether or not the size of a drill hole is the predominant factor in determining the risk of fracture...

The long head of the biceps tendon plays an important role in shoulder stability and its functional absence has been shown to contribute to glenohumeral instability. Congenital absence of the long head to the biceps tendon is rare, although described in the literature. We report the case of an 18-year-old recreational athlete with recurrent shoulder instability and congenital absence of the long head of the biceps tendon (which we term "monocept") and mild ipsilateral upper extremity hemimelia. The patient was treated surgically with posterior capsular shift with anterior Bankart repair without complication...
