Abstract Background Osteoarthritis (OA) of the hip rarely develops in the early second decade. As the incidence of this disease is low, no treatment method has been established. We report two patients with unilateral OA in their early teens in whom the anteversion angle of the femoral neck on the affected side was greater than that on the unaffected side. Case presentation Case 1 was an 11-year-old girl with left coxalgia and limited range of motion. There was no history of femoroacetabular impingement (FAI) or developmental dysplasia of the hip (DDH). Plain X-rays revealed the disappearance of the Y cartilage, joint space narrowing of the left hip, and acetabular/femoral head osteosclerosis. In CT images, the anteversion angle of the femoral neck (lt/rt) was 45/35 degrees. As osteoarthritis was severe, proximal femoral flexional derotational varus osteotomy (PFFDVO) and triple pelvic osteotomy (TPO) were performed. Case 2 was a 13-year-old girl with left coxalgia and limited range of motion. There was no history of FAI or DDH. Plain X-ray revealed irregularity of the left anterolateral femoral head, and a subcartilaginous cyst. In CT images, the anteversion angle of the femoral neck (lt/rt) was 30/20 degrees. As osteoarthritis was severe, PFFDVO was performed. In addition, we resected bone spurs on the femoral head because flexion was limited owing to the presence of osteophytes. In both patients, coxalgia and claudication/gait disorder resolved postoperatively, and joint space narrowing and osteosclerosis improved. However, in Case 1, there was a 3-cm difference in the leg length, and in Case 2, range-of-motion limits remained. Conclusions We present the findings in two patients with unilateral OA in their early second decade in whom the femoral anteversion angle on the affected side was greater than that on the unaffected side. PFFDVO + TPO was performed in Case 1, and PFFDVO + bone spur resection on the femoral head was performed in Case 2. Coxalgia resolved, and plain X-ray demonstrated improvements in OA; however, a difference in the leg length and range-of-motion limits remained.

Osteochondritis ischiopubica or van Neck–Odelberg disease is characterized by atypical ossification of the ischiopubic synchondrosis. Clinical symptoms are usually pain, limping and limited range of motion of the hip joint. Radiologic images may be confused with the possibility of fracture, tumor or inflammation. In some cases it may be difficult to set up the accurate diagnosis, and during the diagnostic process it is essential that van Neck–Odelberg disease should be considered. In this paper the authors draw attention to this rare disorder and they present the history of two patients who posed diagnostic difficulties. Orv. Hetil., 2016, 157(21), 836–839.

Compensatory Motion

The prostheses used by the majority of persons with hand/arm amputations today have a very limited range of motion. Transradial (below the elbow) amputees lose the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Older body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer degrees of freedom. In order to perform activities of daily living (ADL), a person with amputation(s) must use a greater than normal range of movement from other body joints to compensate for the loss of movement caused by the amputation. By studying the compensatory motion of prosthetic users we can understand the mechanics of how they adapt to the loss of range of motion in a given limb for select tasks. The purpose of this study is to create a biomechanical model that can predict the compensatory motion using given subject data. The simulation can then be used to select the best prosthesis for a given user, or to design prostheses that are more effective at selected tasks, once enough data has been analyzed. Joint locations necessary to accomplish the task with a given configuration are calculated by the simulation for a set of prostheses and tasks. The simulation contains a set of prosthetic configurations that are represented by parameters that consist of the degrees of freedom provided by the selected prosthesis. The simulation also contains a set of task information that includes joint constraints, and trajectories which the hand or prosthesis follows to perform the task. The simulation allows for movement in the wrist and forearm, which is dependent on the prosthetic configuration, elbow flexion, three degrees of rotation at the shoulder joint, movement of the shoulder joint about the sternoclavicular joint, and translation and rotation of the torso. All joints have definable restrictions determined by the prosthesis, and task.

Biomechanical Tests

The authors conducted biomechanical tests with 21 firefighters and found that there is a significant correlation between boot height and lower body mobility and that using a fixed boot height mandated by National Fire Protection Association 1971 standard decreased lower body ranges of motion during various firefighters’ job-related tasks. Statistical analysis of large anthropometric data also shows a fixed boot height cannot accommodate a wide range of firefighters’ leg length. These findings indicate that shorter firefighters are likely to have limited lower body mobility due to reduced clearance between the knee and top of the boot and thus decreased space causing greater mechanical binding between multiple layers of turnout pants. The authors discovered a greater negative impact of fixed length of self-contained breathing apparatus cylinder on short firefighters on their upper body mobility, evidenced by limited range of motion in neck extension and lumbopelvic flexion while carrying fire gear compared to without any fire gear.

Bilateral Posterior Shoulder Dislocation

AbstractIntroduction. Bilateral posterior dislocation of the shoulder is a rare injury, accounted for about 2–5% of all shoulder dislocations. Main courses are electrical shock, epilepsy or extreme trauma with uncontrolled muscle forces. We report about a case of bilateral posterior shoulder dislocation without additional fractures but with a concomitant acromioclavicular joint dislocation. Case presentation. A 46-year-old Caucasian motorcyclist presented to our facility after a fall on slippery ground. He claimed pain in both shoulders with limited range of motion. The initial X-rays were inconclusive, clinical examination showed typical findings of a Rockwood injury with an additional limited external rotation so that a posterior shoulder dislocation was suspected. The CT scan confirmed the clinical suspicion. A closed reduction was performed followed by immobilization in a shoulder abduction pillow for 4 weeks and continuous physiotherapy. Upon follow up normal function with full range of motion was observed. Conclusion. A bilateral posterior shoulder dislocation can be caused by trauma and results in a limited range of motion with often additional injuries. Due to the unusually presentation the risk of missing the injury is increased. Therefore it is most important to consider this rare diagnosis and in case of clinical suspicion perform a careful algorithm of diagnostic.

Tuberculosis is caused by Mycobacterium tuberculosis, occurs in about 2 billion people. Approximately 8 million people/year develop the active form.1,2 Tuberculosis in the hand is manifested as osteomyelitis in carpals, metacarpals and phalanges.1 Musculoskeletal tuberculosis occurs, in most cases, through haematogenous dissemination from the primary focus. In immunosuppression circumstances, it is reactivated. Methods: 47 years old lady, who had underlying pulmonary tuberculosis on anti-TB medications since June 2018, presented to us for swelling over right thumb. Associated with tender, erythematous skin and limited range of motion of right thumb. Results: Plain radiograph demonstrated soft tissue swelling, joint space narrowing, mottled lucency of the proximal phalanx and cystic degenerative changes. MRI shows osteomylities proximal phalanx of right thumb. Patient underwent wound debridement of right thumb, culture and sensitivity shows Mycobacterium tuberculosis infections. Post debridement, range of motion of MCP joint of right thumb was improved and anti-TB medications to restart. Discussions: Tuberculosis involvement of the metacarpals and phalanges is a rare presentation of extrapulmonary TB. The radiographic features of osseous tuberculosis are present in conditions such as inflammatory arthritis, pyogenic osteomyelitis, osteopenia, softtissue swelling with minimal periosteal reaction, narrowing of the joint space, cysts in bone adjacent to joints, and subchondral erosions. The gold standard to diagnose is culture of Mycobacterium tuberculosis from bone tissue. Current treatment is a 2 month initial phase of isoniazid, rifampin, pyrazinamide, and ethambutol followed by a 6 to 12 month regimen of isoniazid and rifampin. Conclusion: Finger swelling is a rare presenting sign of disseminated tuberculosis. Early biopsy and appropriate microbiologic testing can avoid diagnostic delay. References: Malaviya AN, et al.

Charcot arthropathy is a chronic, degenerative condition and is associated with decreased sensorial innervation. Numerous causes of this arthropathy have been described. Here we report a case of neuropathic arthropathy secondary to syringomyelia which was misdiagnosed as a soft tissue tumor and treated surgically and additionally with radiotherapy at another institution. The patient had clinical and radiological signs of syringomyelia, associated with a limited range of motion, swelling, and pain in the affected joint. Neuropathic arthropathy, although less common, should be considered in cases of unexplained joint swelling, pain, and limited range of motion of the affected joint.
