[Rupture of the distal biceps tendon. Case report--modified after-care].

The surgical therapy of the rupture of a distal biceps tendon and a modified postoperative treatment is described. Mainpoint is the early treatment in anaclisis of Kleinert as it is standardized in the treatment of ruptures of the flexor tendons of the hand. A forearm orthesis with a simply ROM-joint without reboundmechanism was used. Possible benefits are shown and further industrial evolution seems to be indicated.

MR imaging of osteochondral and articular lesions.

MR imaging provides clinically useful information in assessing the elbow joint for osteochondral and articular lesions. Post-traumatic osseous abnormalities well seen by MR imaging include radiographically occult fractures, stress fractures, bone contusions, osteochondritis dissecans, and chondral defects. Intraarticular loose bodies can be identified with MR imaging, especially if fluid or contrast material are present within the elbow joint. MR imaging can also provide additional information regarding synovial osteochondritis, osteoarthritis, and bursitis about the elbow.

Heterotopic ossification in a throwing athlete after elbow arthroscopy.

A case of heterotopic ossification occurring after elbow arthroscopy in a young, healthy, throwing athlete is reported. The heterotopic bone caused a loss of motion post-arthroscopy in the patient and was confirmed with plain radiographs and bone scan. Twenty-two months after elbow arthroscopy, the patient underwent an open excision of the heterotopic bone. He returned to competitive throwing the next season. While this complication is rare after such minimally invasive procedures, this entity should be considered in the differential diagnosis in the throwing athlete who is unable to recover full range of motion after elbow arthroscopy.

Physical examination of the thrower's elbow.

The physical examination of the thrower's elbow presents the clinician with the clinical challenge of differentially diagnosing specific pathologies. The examination should include a thorough history and a well-organized physical examination, which relies on an extensive knowledge of the functional anatomy of the elbow. The components of an elbow examination include inspection/observation, palpation of bony and soft tissues, range of motion assessment, resisted muscle testing (both manual and mechanical), neurologic testing, and special tests. The special tests commonly performed on the thrower's elbow are the Tinel test, tennis elbow sign, ulnar collateral ligament stability testing, valgus extension overload test, and radiocapitella chondromalacia test. Other tests include radiographic examination, such as computerized tomograph arthrogram and magnetic resonance imaging testing. Information presented in this paper will provide the clinician with a systematic and thorough evaluation process for the thrower's elbow.

[Excision of heterotopic new bone around the elbow in patients with head injury: 51 cases].

PURPOSE OF THE STUDY: Neurogenic paraosteoarthropathy of the elbow is a frequent complication in head injury patients. The functional impairment may be severe. The purpose of this work was to evaluate the efficacy of our medico-surgical approach and to determine indications for surgery. MATERIAL AND METHODS: We analyzed retrospectively a continuous series of 44 patients (51 elbows) with neurogenic heterotopic new bone of the elbow joint managed from 1993 to 2000. The heterotopic bone had developed on a central deficit limb in 70% of the patients. Flexion-extension was limited in all patients, and pronation-supination in nine. The ulnar nerve was compressed by the heterotopic bone in half of the patients. A 3D reconstruction CT-scan with contrast injection was obtained in all patients. We consider did not the classical criteria for bone maturation to assess operability. Using an adapted approach, we removed the heterotopic new bone to enable complete elbow motion. Associated procedures were performed in fifteen patients due to persistent intraoperative joint stiffness related to muscle-tendon retraction. We did not prescribe diphosphonates or radiotherapy postoperatively. RESULTS: At 45 months follow-up, one patient had been lost. Relative gain was considered very good in 34 elbows, good in 13 and fair in 3. There were no cases of lost motion. There were no recurrences causing joint limitation, but two of nine cases of radioulnar synostosis recurred. DISCUSSION: Neurogenic paraosteopathy of the elbow impairs joint function and may lead to ulnar nerve compression. The goal of surgery is to improve function. The analysis of our results show that early surgery yields good results without complementary treatment, irrespective of the patient's overall functional deficit or cognitive status and irrespective of the localization of the hetertopic bone. The essential prognostic factor for the quality results is the neurological status of the limb, particularly the degree of spasticity and muscle-tendon retraction.

Functional restoration of elbow extension after spinal-cord injury using a neural network-based synergistic FES controller.

Individuals with a C5/C6 spinal-cord injury (SCI) have paralyzed elbow extensors, yet retain weak to strong voluntary control of elbow flexion and some shoulder movements. They lack elbow extension, which is critical during activities of daily living. This research focuses on the functional evaluation of a developed synergistic controller employing remaining voluntary elbow flexor and shoulder electromyography (EMG) to control elbow extension with functional electrical stimulation (FES). Remaining voluntarily controlled upper extremity muscles were used to train an artificial neural network (ANN) to control stimulation of the paralyzed triceps. Surface EMG was collected from SCI subjects while they produced isometric endpoint force vectors of varying magnitude and direction using triceps stimulation levels predicted by a biomechanical model. ANNs were trained with the collected EMG and stimulation levels. We hypothesized that once trained and implemented in real-time, the synergistic controller would provide several functional benefits. We anticipated the synergistic controller would provide a larger range of endpoint force vectors, the ability to grade and maintain forces, the ability to complete a functional overhead reach task, and use less overall stimulation than a constant stimulation scheme.

Tear of the distal biceps tendon presenting as an antecubital mass: magnetic resonance imaging appearances.

OBJECTIVE: To present the magnetic resonance imaging (MRI) findings for tear of the distal biceps tendon presenting as a soft-tissue mass in the antecubital fossa. PATIENTS AND METHODS: The authors identified four patients who had been referred for MRI of an antecubital soft-tissue mass and in whom a tear of the distal biceps tendon was found. RESULTS: All four patients had typical MRI findings for a tear of the distal biceps tendon. In three, a tear at the insertion of the tendon onto the radial tuberosity was associated with small fluid collections at the site of the tear. In one patient there was thinning of the tendon and fluid within the tendon sheath. The diagnosis was confirmed by clinical correlation and follow-up of at least 1 year (in two patients) or by surgical exploration (in two). CONCLUSIONS: With knowledge of the MRI appearance of distal biceps tendon tear, it should be possible to correctly diagnose the problem, even when the clinical presentation does not suggest the diagnosis.

Educational techniques used in occupational therapy treatment of cumulative trauma disorders of the elbow, wrist, and hand.

OBJECTIVE: This study examined patient education techniques used by occupational therapists when treating cumulative trauma disorders (CTDs) of the elbow, wrist, and hand. METHOD: A self-administered survey was sent to 232 registered occupational therapists whose primary area of practice was hand therapy. The questionnaire sought information about specific content areas and methods (i.e., media, format) used to educate patients about preventing the recurrence of CTDs in the elbow, wrist, and hand. RESULTS: One hundred twenty-eight therapists responded to the survey. A majority of respondents (n = 116) reported that patient education content area consisted of anatomy of the joint, the CTD disease process, and job modification. Verbal instruction, illustrations, and pamphlets and handouts were the most frequently used forms of educational media. A majority of respondents (n = 111) also reported that individual interaction was the most common format of patient education. CONCLUSION: The findings indicate that a majority of therapists use the same patient education techniques with regard to content areas, media, and format, regardless of the area being treated (i.e., elbow, wrist, hand). Furthermore, it appears that therapists with specialty training in CTDs more frequently include anatomy of the elbow, job modification, and proper body mechanics in the content of their patient education about the elbow.

Injuries in young athletes.

UNLABELLED: Most injuries in children's sports are minor and self-limiting, suggesting that children and youth sports are safe. A child's skeletal system shows pronounced adaptive changes to intensive sports training. Sports injuries affect both growing bone and soft tissues and could result in damage of the growth mechanisms with subsequent life-lasting damage. During growth there are significant changes in the biomechanical properties of bone. In young athletes, as bone stiffness increases and resistance to impact diminishes, sudden overload may cause bones to bow or buckle. Epiphyseal injuries are usually due to shearing and avulsion forces, although compression also plays a significant role. Given the remarkable healing potential of bone in youngsters, fractures that initially united with some deformity can completely remodel and appear totally normal in later life. CONCLUSION: As the risk of injuries sustained by young athletes can be significant, it is essential that training programmes take into account their physical and psychological immaturity, so that growing athletes can adjust to their own body changes.

The role of imaging of work-related upper extremity disorders.

Work-related upper extremity disorders can pose a diagnostic and management challenge because the nontraumatic disorders that are often believed to be caused by repetitive work activities can and do occur without any apparent provoking activity and can be caused or associated with many systemic medical conditions. One mainstay in the assessment of hand and arm disorders remains imaging. Imaging capabilities have made incredible advances with the advent of MRI, CT, ultrasound, bone scan, and numerous technologies that enable clinicians to view fine details of anatomy and pathology. This article reviews the potential imaging choices and clinical indications for work-related injuries of the elbow, hand, and wrist.

Special concerns of the female athlete.

The majority of injuries sustained by female athletes are due to participation in sports rather than their sex. Anatomic, hormonal,and functional differences should be understood when treating the female athlete. Screening should be done for eating disorders and the female athlete triad. Female athletes have increased rates of injury to the anterior cruciate ligament and patellofemoral disorders compared with their male counterparts.
