Recurrent anterior dislocation of shoulder joint.

111 patients with fresh dislocation of shoulder joint were treated with modified Putti-Platt procedure. Of these, 17 had recurrent anterior dislocation. 13 patients were followed up on the average for 25 years. According to Rowe criteria, 10 patients (76.9%) showed excellent results, 2 (15.4%) good, and (7.7%) fair. No recurrence and restriction of external rotation were found. Clinical experience and fetal investigation on congenital factors of recurrent shoulder dislocation were described.

[The shoulder joint--diagnostic imaging].

In the assessment of shoulder joint abnormalities plain films must still be used today as primary imaging modality. For soft tissue, cartilage, tendon and ligament lesions, CT with arthrography and particularly MRI with arthrography is available today. Especially latter method leads to a significantly extended diagnosis, which in many cases implies a major therapeutical significance.

[Evaluation of 67Ga accumulation around the shoulder joint--comparison with 99mTc-MDP].

67Ga scintigraphy was performed in 865 patients, and in 1078 examinations. 67Ga accumulation was evaluated retrospectively for asymmetric accumulation in the shoulders. Approximately 50% of patients showed no asymmetric distribution of 67Ga in the shoulders. About 40% of patients showed increased accumulation in the right side and about 10% of patients showed increased accumulation in the left side. A change of 67Ga distribution in the shoulder joints was recognized in about 30% of patients during the follow-up study. Reasons for asymmetric distribution of 67Ga in the shoulders were considered to be due to bone metastasis, changes of local blood flow, edema, irradiation, muscle atrophy after cerebral paralysis, and operation. 67Ga scintigraphy showed a broader range and more prominent accumulation in the soft tissues around the shoulder joint than 99mTc-MDP scintigraphy. The accumulation of 99mTc-MDP was recognized to be in the center of the region of 67Ga accumulation. 99mTc-MDP scintigraphy showed more prominently increased accumulation than 67Ga scintigraphy in patients with osseous lesions. Similar factors appeared to have had an influence on the abnormal accumulation of 67Ga and 99mTc-MDP around the shoulder joint.

Arthroscopic relationship of the axillary nerve to the shoulder joint capsule: an anatomic study.

Twelve right shoulders in fresh cadavers were dissected to determine the relation of the axillary nerve to the shoulder capsule and glenoid. Needles transfixed the nerve to the capsule and into the shoulder joint. Arthroscopy was performed to determine the location of the needles on the glenoid clock. The needles were then removed and the position of the shoulder changed to determine the effect on the position of the axillary nerve. The axillary nerve was held to the shoulder capsule with loose areolar tissue in the zone between 5 and 7 o'clock and was close to the glenoid in the neutral position, in extension, and in internal rotation. With shoulder abduction, external rotation, and perpendicular traction, the capsule became taut and the axillary nerve moved away from the glenoid. Abduction, external rotation, and perpendicular traction increase the zone of safety during arthroscopic anteroinferior capsulotomy adjacent to the glenoid between the 5 and 7 o'clock positions.

Intra-articular elastofibroma of the shoulder joint.

A 19-year-old man presented with an elastofibroma in his left shoulder joint. The patient had had limitation of motion in his left arm for 3 years, especially when rotating internally. Radiography of his left shoulder showed bone erosion in the neck of the humerus. On MR imaging, a soft tissue mass was noted in the shoulder joint eroding bone. The mass showed similar signal intensity to that of surrounding muscles on T1- and T2-weighted images. At surgery, a soft, encapsulated mass was found attached to the subscapularis muscle. It was pathologically confirmed as an elastofibroma. This unusual manifestation of an elastofibroma is discussed.

Dislocation of the shoulder joint with ipsilateral humeral shaft fracture: two case reports.

INTRODUCTION: A combination of the shaft fracture of the humerus with shoulder dislocation is a rarely documented injury. Moreover, few reports describe a long-term outcome after a follow-up period over 10 years. The present article is the first report of long-term clinical results obtained with this combined injury. MATERIALS AND METHODS: We present two cases of the dislocation of the shoulder joint with ipsilateral humeral shaft fracture. One is an anterior dislocation and the other is posterior. The anterior dislocation was closely reduced on the date of injury, but the posterior dislocation required open reduction 6 weeks after the injury because it was missed at the initial diagnosis and identified 4 weeks after the injury. In the latter case, shoulder pain and limitation of the motion persisting after the first surgery had to be treated by anterior acromioplasty and arthrolysis of the shoulder. In both cases, the humeral fracture was fixed by retrograde intramedullary nailing using a Küntscher nail and successful bone union was achieved. RESULTS: At over 10-year follow-up examination, both patients had no limitation in activities of daily living and no restrictions to their normal occupation. The radiographs of the shoulder joint demonstrated good clinical results, with no degenerative change or osteonecrosis. CONCLUSION: We have experienced two cases of dislocation of the shoulder joint with ipsilateral humeral shaft fracture and reported long-term results over 10 years. Good clinical results were demonstrated in both cases.

Open and closed kinetic chain exercises improve shoulder joint reposition sense equally in healthy subjects.

OBJECTIVE: To compare the effects of open and closed kinetic chain exercise on shoulder joint reposition sense. DESIGN AND SETTING: Subjects with no previous upper extremity injury participated in a 6-week exercise program consisting of 3 sessions per week. SUBJECTS: Thirty-nine healthy male military cadets: 13 each in the open, closed, and control groups. MEASUREMENTS: Each subject was pretested and posttested for both active and passive joint reposition sense at 30 degrees external rotation, 30 degrees internal rotation, and 10 degrees from full external rotation. RESULTS: The open and closed kinetic chain groups de- creased in reposition sense error scores in comparison with the control group, but no difference was found between the 2 training groups. CONCLUSION: Our findings suggest that shoulder joint reposition sense can be enhanced with training in healthy subjects. Also, open and closed kinetic chain exercises appear to be equally effective in improving shoulder joint reposition sense.

Shoulder joint position sense improves with elevation angle in a novel, unconstrained task.

Proprioception, encompassing the submodalities of kinesthesia and joint position sense, is important in the maintenance of joint stability, especially in the shoulder. The purpose of this study was to examine the effects of plane and elevation angle on unconstrained shoulder joint position sense. Twenty-two subjects (12 male, 10 female) without a history of shoulder pathology were recruited from a university campus. Subjects attempted to replicate, with respect to plane and elevation angles, various target positions. Target positions consisted of five plane angles at 90 degrees of arm elevation and five arm elevation angles in the scapular plane. All target positions were tested twice to assess the reliability of the measurement. Intraclass correlation coefficients were generally low across target positions, possibly owing to the novelty and demanding nature of the task. No differences in repositioning errors were observed between plane angles (p = 0.255). Repositioning errors decreased linearly as the elevation angle increased from 30 degrees to 90 degrees (p = 0.007) and increased again from 90 degrees to 110 degrees of elevation (p = 0.029). Our results suggest that unconstrained joint position sense may be enhanced with increased muscular activation levels. Further, afferent feedback from musculotendinous mechanoreceptors may dominate over that from capsuloligamentous sources in unconstrained movements.

Innervation of the human shoulder joint and its implications for surgery.

The distribution and variability of the nerves innervating the shoulder joint were determined in 25 fresh human adult cadavers using 3.5x magnification for dissection. The results showed that 100% of the specimens had dual innervation of the coracoclavicular ligaments, the subacromial bursa, and the acromioclavicular joint. This dual innervation was from the articular branches of the suprascapular nerve and of the lateral pectoral nerve. Constant relationship of these 2 nerves to bony landmarks will permit anesthetic blocks for diagnosis and possible therapeutic intervention. A consistent pattern of innervation of the posterior and inferior shoulder joints also is described.

The sensory innervation of the shoulder joint of the mouse.

The ultrastructure and location of sensory nerve endings in the shoulder-joint capsule, its tendinous reinforcements and in the periarticular connective and muscle tissue have been studied by means of light and electron microscopy in adult female white NMRI-F2 laboratory mice, aged 2.5-13 months. Most of the sensory nerve endings were detected in the fibrous layer of the joint capsule or in the inserting tendons. The identified lamellated corpuscles of the Pacini type are small and sometimes associated with Golgi tendon-organs. Large Vater-Pacini corpuscles were not detected. Ruffini corpuscles are found in small numbers only in the moderately dense connective tissue of the joint capsule. Golgi tendon organs were found mainly at the muscle-tendon junction of the muscles surrounding the joint. Muscle spindles have been identified mainly in periarticular muscles close to the muscle-tendon junctions. The number and distribution of the different types of mechanoreceptors investigated in the present study suggest that periarticular corpuscular sensory nerve endings play an important role in shoulder-joint control and mobility. The occurrence of small uniformly shaped lamellated corpuscles of the Pacini type in qualitatively different areas of surrounding tissue implies that they are susceptible to different kinds of mechanical stimuli.

Topography of mechanoreceptors in the shoulder joint region--a computer-aided 3D reconstruction in the laboratory mouse.

BACKGROUND: We investigated the pattern of distribution of corpuscular sensory nerve endings in the shoulder region of the laboratory mouse in relation to their functional properties. METHODS: Twelve adult female white NMRI-F2-mice were used. The topography of sensory nerve endings in the shoulder joint region was reconstructed by three-dimensional image processing by using serial silver-stained sections of paraffin-embedded samples. Semithin sections obtained from additional samples were used for light microscopy. RESULTS: Within the fibrous layer of the joint capsule, three types of mechanoreceptors were identified: small lamellated corpuscles of the Pacini type, Ruffini corpuscles, and Golgi tendon organs. Intracapsular small lamellated corpuscles of the Pacini type (in an average number of 29/joint) were found mainly in three areas: in the predominantly flaccid tissue of the axillary region, in the denser ventromedial parts of the capsule, close to the scapula, and in the tight texture of the fiber bundles near the glenoid labrum. Ruffini corpuscles were identified only in small numbers (2/joint) in the ventral aspect of the articular capsule of two animals. Golgi tendon organs (14 or 15 receptors/joint) were discovered predominantly in close vicinity to the joint capsule at the muscle tendon junction of the inserting rotator cuff muscles and in the biceps brachii and triceps brachii muscles. CONCLUSIONS: In view of their location in the shoulder joint capsule and the glenoid labrum, corpuscular mechanoreceptors evidently play an important role in joint control by inducing protective reflex actions in phases of extreme or abnormal movement. The density of sensory receptors in distinct areas of the shoulder joint capsule appears to be related to zones that are subjected to increased biomechanical stress during physical activity.

[Reconstruction of the shoulder joint function in the older obstetrical palsy].

OBJECTIVE: To study the reconstructional method and effect of shoulder joint function in the older obstetrical palsy with medial rotation contracture deformity. METHODS: From April 1996 to July 1999, 7 patients of older obstetrical palsy were adopted in this study. Among them, there were 5 males and 2 females, aged from 13 to 21 years old. No previous operation history and the main deformity was medial rotation contracture of shoulder. During operation, these patients were treated with "Z"-shape elongation of the tendon of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. RESULTS: Followed up for 6 to 44 months(averaged 19 months), the Gilbert grading and Mallet scoring were 1.57, 7.57 preoperatively versus 3.45, 10.86 postoperatively, the abduction and external rotation of the shoulder joints recovered obviously. CONCLUSION: It is an effective operation for the older obstetrical palsy with medial rotation contracture of shoulder.

Impingement of the rotator cuff in athletes caused by instability of the shoulder joint.

An impingement of the rotator cuff can be caused by chronic anterior instability of the shoulder joint. This particular disease is often found in athletes engaged in overhead motion in abduction/external rotation of the arm, such as in ball sports like volleyball or European handball, racket sports like tennis or badminton, or swimming. For those patients that cannot be cured by conservative treatment such as muscular stabilization, surgical treatment is indicated: anterior reconstruction of the capsule and/or the glenoid labrum, and in addition--if necessary--subacromial decompression and revision of the rotator cuff. Between October 1988 and April 1992, we operated on 66 shoulders in 64 top athletes suffering from chronic anterior or multidirectional instability of the shoulder joint that had caused an impingement syndrome of the rotator cuff. In all cases, the athlete was unaware of the instability. Conservative treatment had been unsuccessful. Surgical treatment was successful in close to 90% of the athletes.
