[Percutaneous surgical treatment of two epiphyseal plate fractures of the proximal humerus].

We report two cases of Salter 2 displaced epiphyseal detachment of the proximal humerus treated successfully by percutaneous reduction and centromedular nailing. This surgical treatment was required because of the irreducibility of the lesion in one patient and instability in the other. This percutaneous technique can be recommended after failure of orthopedic treatment and is an attractive alternative to open surgery.

Electromyographic findings in shoulder dislocations and fractures of the proximal humerus: comparison with clinical neurological examination.

There is no consensus of opinion about the frequency of associated nerve lesions in anterior shoulder dislocations and fractures of the proximal humerus. We undertook a prospective study to assess the incidence, the severity of the nerve injury and the diagnostic value of electromyographic examination; 215 patients were included. We performed neurological examination and needle electromyography (EMG). Nerve injury was graded according to a denervation score at the EMG. EMG disorders were seen in 133 patients (62%). Testing of sensibility and clinical reflexes proved not to be a reliable indicator for EMG abnormalities. Detection of axonal lesions by grading muscle strength based on the MRC score after these shoulder traumas is difficult. The findings of this study imply that by clinical examination alone a large number of axonal lesions remain undetected.

Axillary artery injuries after proximal fracture of the humerus.

Although axillary artery injury occurs frequently with dislocations of the shoulder and fractures of the clavicle, it is rarely associated with fractures of the proximal humerus. If the axillary artery is damaged, prompt recognition and treatment are necessary to salvage the involved extremity.

Four-part fracture dislocation of the proximal humerus: an arthroscopic approach.

The 4-part fracture dislocation of the proximal humerus remains an unsolved problem in young patients. The majority of 4-part fracture dislocations are best managed by humeral head replacement, although open reduction and internal fixation in young patients with good bone quality may be considered. Better results are obtained associated with limited exposure, careful soft tissue dissection, and stable fixation. We present an unpublished technique of reduction with arthroscopic assistance and percutaneous stabilization, which preserves the soft tissue around the fragments, avoiding the deltopectoral approach.

Arthroscopic subscapularis tenolysis: a technique for treating refractory glenohumeral stiffness following open reduction and internal fixation of a displaced three-part proximal humerus fracture.

This case illustrates the treatment of a stiff shoulder following open reduction and internal fixation of a three-part fracture of the proximal humerus. Motion could not be improved with physical therapy or with manipulation under general anesthesia. Arthroscopic subscapularis tenolysis provided a dramatic increase in range of motion. The unique pathological findings may render such cases refractory to manipulation because of thick unyielding scar tissue. In such cases, arthroscopic subscapularis tenolysis may provide the only means of improving the final range of motion.

Avulsion fracture of the medial and lateral epicondyles of the humerus.

It is still controversial whether fresh avulsion fractures of the medial or lateral epicondyle of the humerus in adults should be treated conservatively or surgically. We monitored 12 patients to consider treatment selection. The patients were examined for site and size of bone fragment, degree of displacement, dislocation of the elbow joint, method of treatment, and bone union and elbow stability. The treatment results were scored according to the Elbow Assessment Score System, and the scores ranged from 86 to 100 points. The scores did not differ significantly among any of the patients, whether treated conservatively or surgically. Although surgery produces good results, conservative treatment can be selected for patients in whom the maximum diameter of bone fragment is 13 mm or less or the displacement of the bone fragment is 9 mm or less.

Isolated fractures of the greater tuberosity of the proximal humerus.

This review addresses isolated greater tuberosity fractures of the proximal humerus. The important aspects of the epidemiology, anatomy, fracture classification, associated injuries, and treatment are discussed. Although isolated greater tuberosity fractures are well recognized, there are few studies that specifically evaluate the outcome of these injuries. Our experience and review of the recent literature suggest that more precise evaluation of diagnostic criteria, treatment selection, and outcome is required.

Surgical technique for supracondylar fracture of the humerus with percutaneous leverage pinning.

Percutaneous pinning with a leverage technique for supracondylar fracture of the humerus was performed in 36 elbows in 35 children. The patient was placed in the lateral position with the forearm hanging. Under radiographic imaging, a Kirschner wire, as a reduction pin, was inserted into the fracture line from the dorsal side, passed through the posterior cortex of the proximal fragment, and turned distally. After reduction of the posterior displacement by the leverage technique, the reduction pin was driven into the anterior cortex of the proximal fragment. Subsequently, a Kirschner wire was inserted from the lateral condyle for fixation between the proximal and distal fragments. This percutaneous pinning technique was successfully performed in 32 of 36 elbows, with excellent functional results in 28 elbows and good results in 4, as well as excellent cosmetic results in 27 elbows and good results in 5, based on the evaluation criteria of Flynn et al.

Outcomes of hemiarthroplasty for fractures of the proximal humerus.

We reviewed 80 shoulders (72 shoulders in 71 patients) treated with hemiarthroplasty. At follow-up, 66 patients (93%) were pain-free and satisfied with their results; the mean American Shoulder and Elbow Surgeons score was 76.6, the mean Simple Shoulder Test score was 7.5, the average forward flexion was 128 degrees, external rotation was 43 degrees, and internal rotation was to L2. Radiographic analyses revealed nearly anatomic tuberosity reconstruction in 58 shoulders, heterotopic ossification in 18, pseudosubluxation in 10, and superior migration in 15. Patients with superior migration had statistically lower mean American Shoulder and Elbow Surgeons scores, mean Simple Shoulder Test scores, and decreased forward flexion. Tuberosity complications occurred in 16 shoulders. Malunion of the greater tuberosity was the most common complication. Healing of the greater tuberosity more than 2 cm below the humeral head correlated with a worse functional result. Hemiarthroplasty for indicated fractures of the proximal humerus results in shoulder-level function and reproducible pain relief.

A comparison of double-plate fixation methods for complex distal humerus fractures.

A modified method of fracture fixation of complex distal humeral fractures with medial and lateral plates and bolts was biomechanically tested and compared with previously described fixation techniques. Compressive stiffness coefficients were determined for three classes of fixation before and after fatigue cycling. This procedure was followed with compressive loading to failure. The results show that in the most unstable fracture type tested this new fixation method provides increased strength and stability. Early clinical follow-up examinations of patients treated with this technique show that this method is a reasonable fixation alternative for the complex distal humerus intercondylar fracture.

Three-dimensional corrective osteotomy for treatment of cubitus varus after supracondylar fracture of the humerus in children.

Cubitus varus deformity after supracondylar fracture of the humerus in children generally includes deformities of varus, hyperextension, and internal rotation. Presently almost all corrective osteotomies for treatment of cubitus varus deformity have been limited to correction of only the varus or of the varus and hyperextension deformity. Electromyographic study and stick picture motion analysis have revealed unphysiological joint motion and muscle activity around the joint in elbows with cubitus varus, hyperextension, and internal rotation deformity. On this basis we have successfully attempted simultaneous correction of all three deformities. The end results in 41 elbows have been satisfactory. In conclusion, we recommend simultaneous correction of the three elements of cubitus varus deformity to restore anatomic alignment of the elbow joint.

Shoulder function after displaced fractures of the proximal humerus.

It is difficult to predict the outcome of comminuted fractures of the proximal humerus and give guidelines for optimal treatment. Different treatment modalities are available, and there are various scoring systems for postoperative evaluation. The aim of this study was to assess the functional outcome after three- and four-part fractures of the humeral head in 38 patients, with a 3-year follow-up. Twenty-eight patients were treated conservatively, seven were operated on with open reduction and internal fixation, and three received a hemiarthroplasty. All patients were examined clinically and radiographically. Neer and Constant scoring systems were used. The functional outcome after three-part fractures was generally good. Twenty-five of 26 patients with a three-part fracture could accept their shoulder situation. Range of motion was significantly lower in the four-part fracture group. Mean flexion was 89 degrees compared with 120 degrees in the three-part fracture group. Necrosis of the humeral head was found in 2 cases, both four-part fractures. Osteoarthrosis developed in 13 cases (6 with a three-part fracture, 7 with a four-part fracture). No disability was found in 16 of 24 patients with three-part fractures, and in 4 of 11 patients with four-part fractures. There was strong agreement between the Constant score and the patients' opinions.

Outcome after hemiarthroplasty for three- and four-part fractures of the proximal humerus.

We reviewed 27 patients who had sustained displaced three- or four-part fractures of the proximal humerus and who were treated with a humeral hemiarthroplasty. Seventeen patients had a three-part fracture, and 10 had a four-part fracture. The mean follow-up period was 39 months (12 to 94 months). All fractures were classified according to Neer's classification. The Constant score was used for their follow-up evaluation. The median Constant score at follow-up was 51 for the three-part fractures and 46 for the four-part fractures. The median range of movement for all the patients in flexion was 70 degrees, abduction 70 degrees, internal rotation 50 degrees, and external rotation 45 degrees. Nine patients still had moderate or severe pain. Eight patients had moderate or severe disability. Our results were disappointing, and further studies on open reduction and fixation are therefore justified.

[Preliminary results of retrograde nailing of the humerus].

A group of nine patients with a diaphyseal fracture of the humerus and treated with retrograde nailing were studied with a mean follow-up of 15.3 months. Six patients with a humeral fracture without neurological deficit showed a good shoulder and elbow mobility at the last visit. Three patients with neurological lesion preoperatively suffer from a diminished range of movement not related to the surgical procedure. During the operation and postoperatively we found no complication related to the implant and more precisely we could not find a iatrogenic fracture or nervous lesion except one intraoperative lesion of the radial nerve probably related to an important traction movement during reduction with complete remission. Consolidation has been achieved for all fractures but one. This patient suffers from a lesion of the brachial plexus with complete plegia of the arm and a vascular lesion. This patient had to be reoperated for an atrophic non-union by bone grafting and plate fixation. The retrograde nail is a good implant and must be considered in our treatment plans as much as conservative treatment or surgical treatment with plating, anterograde nailing or the use of an external fixator. Only then will we be able to give to the patient the most adapted treatment for his fracture.

Percutaneous minimal osteosynthesis of fractures of the proximal humerus in elderly patients.

INTRODUCTION: The aim of this study was to evaluate the subjective and objective outcome of the percutaneous minimal osteosynthesis in elderly patients. Untreated, unstable and dislocated proximal humeral fractures show poor functional and subjective results. Reduction and fixation of the fragments is essential to achieve a good clinical outcome. Especially noted in elderly patients, the osteosynthesis is concurrent with the implantation of a prosthesis. PATIENTS AND METHODS: We examined 31 patients with a mean age of 72 years (51-87) after an average follow-up period of 15.8 months (9-31). To assess the functional and subjective results, we used the Constant Score as well as an adapted version of the Oxford Shoulder Score. Radiographs in two planes displayed the anatomical situation, the healing of the fracture, and the evidence or absence of avascular necrosis. RESULTS: There were no local complications such as hematomas or wound infections. The results of the Constant Score showed an average of 63.5 Pts. (18-82 Points) and adapted to age and gender by 90.2% (28.1-118.8%). Compared with the uninjured arm with an average of 77.1 Points (20-89 Points) and 109.5% (29-129%) respectively, we achieved an average functionality of 82.6%, operated versus non-operated side. All but one fracture, that showed signs of avascular necrosis with disintegration of the humeral head, were fully consolidated. The subjective results were very good in 18 patients, good in 7, satisfying in 3 and poor in 3 patients. CONCLUSION: Our data indicate that the percutaneous minimal osteosynthesis is a valuable method for the fixation of proximal fractures of the humerus in elderly patients. The technique has a very low rate of complications and the time of convalescence is short. If closed reduction fails or a stable percutaneous fixation of the fracture by K-wires is not possible, the change to open reduction and internal fixation or the implantation of a prosthesis is required.

Fractures of the humerus.

Humeral fractures are the least common long bone fracture in small animals. The low incidence of these fractures combined with the unique anatomy of the humerus makes repair of humeral fractures challenging. This chapter provides a review of humeral fracture management.
