BACKGROUND: The most common sequela of neonatal brachial plexus palsy is an internal rotation contracture of the shoulder that impairs function and leads to skeletal deformation of the glenohumeral joint. Treatment options include release, transfers, and humeral osteotomy, all ultimately striving for better function through increased external rotation. Prior studies have shown that neonatal brachial plexus palsy alters humeral retroversion but with conflicting findings. We studied retroversion in children with internal rotation contractures from neonatal brachial plexus palsy to clarify its effect on version and surgical planning...

The increasing demand which requires ascertaining the legal age of undocumented individuals who reach the various countries of the European Community means that new lines of research must be developed which help respond to questions posed by the Justice Administration. For this reason, this study has been designed on the basis of fusion times of the proximal humeral epiphysis. Moreover, the ultrasound scan has been used as the diagnostic method. It is a non-invasive technique, unlike the radiograph, which is used under current standards for the forensic diagnosis of age...

The majority of dislocated, intra-articular fractures are treated with an open reduction and internal fixation. In this paper we describe a variety of dorsal approaches to the distal humerus. Beside the dorsal approach through an olecranon osteotomy we also discuss the alternative dorsal approaches without osteotomy and their advantages and drawbacks. Moreover we discuss the preoperative planning and operative procedure. Early functional rehabilitation, without weight bearing, is important to achieve an optimal outcome...

BACKGROUND: We developed a frozen autograft technique in which a tumor-bearing bone was treated with liquid nitrogen for reconstruction. The purpose of this study was to evaluate the functional outcomes of this technique after resection of humeral bone tumors. PATIENTS AND METHODS: Eight patients were included in the study. The freezing range was classified into 2 groups, depending on whether the joint surface of the humeral head was frozen. RESULTS: In the joint freezing group, the mean active shoulder abduction and flexion were 43...

Tears of the rotator cuff are frequent. An estimated 250,000 to 500,000 repairs are performed annually in the United States. Rotator cuff repairs have been successful despite fatty infiltration and atrophy of the rotator cuff muscles. Although the emphasis in rotator cuff repair has historically focused on re-establishing the tendon attachment, there is growing interest in and understanding of the role of the superior capsule. The superior capsule is attached to the undersurface of the supraspinatus and infraspinatus muscle-tendon units, and it resists superior translation of the humeral head...

Rotator cuff disease remains a complex clinical problem with significant variation in pathology, clinical presentation, and management options. Functionally, humeral head depression is critical in restoring or maintaining arm elevation, and the shoulder superior capsule serves in this important function. Could disruption of the shoulder superior capsule be the "essential lesion" of rotator cuff disease? Possibly, but many questions remain unanswered, and substantial scientific evidence is required before we can assert with certainty that disruption of the superior capsule with resultant superior instability of the humeral head is the essential lesion of rotator cuff disease...

PURPOSE: Reverse shoulder arthroplasty becomes more widely used as treatment for patients with complex cuff arthropathy. Theoretically, a higher retroversion of the humeral component leads to an increase in external rotation ROM and a decrease in internal rotation ROM. There is no consensus in optimal retroversion orientation. We retrospectively describe the effect of retroversion of the humeral component. We hypothesize that 20° humeral retroversion improves postoperative ROM, strength or clinical outcome scores compared to neutral retroversion...

BACKGROUND: Assessment of glenohumeral subluxation is essential in preoperative planning of total shoulder arthroplasty. The purpose of this study was to evaluate a 3-dimensional (3D) glenohumeral subluxation index (GHSI) in shoulders with primary osteoarthritis (OA) and its relationship with morbid glenoid retroversion. METHODS: The 3D computed tomography reconstructions of 120 healthy shoulders and 110 shoulders with primary glenohumeral arthritis (OA group), classified according to Walch's glenoid morphology, were analyzed...

BACKGROUND: Total elbow arthroplasty is a treatment for unreconstructable distal humeral fractures; however, longevity of the implant remains a concern in younger, more active patients. Distal humeral hemiarthroplasty (DHH) offers an alternative with multiple advantages. METHODS: This is a retrospective study of 10 patients who underwent DHH for distal humeral fractures during a 4-year period (2008-2012) by a single surgeon. Patients underwent testing of range of motion, Mayo Elbow Performance Score, Disabilities of Arm, Shoulder and Hand, visual analog scale, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons scores...

The aim of this retrospective study was to investigate the frequency of persistent ulnar affection in patients who underwent open reduction and internal fixation (ORIF) of distal humeral fractures without ulnar nerve transposition or mobilisation. Eighty-two patients (53 women), mean age 62 years, were, at a mean of 48 months, reviewed through medical records and a subjective evaluation form concerning ulnar nerve problems. Ulnar nerve affliction, in most cases regarded as mild, was experienced by 22 patients (27%; 14 women) and significantly associated with multiple surgeries...

INTRODUCTION: Displaced unstable distal third fractures of the humeral diaphysis are treated surgically through open reduction and internal fixation. Conventionally, surgeons prefer using long plates for secure fixation; however, we performed short plate dual plating for robust fixation that required a smaller incision and less dissection through an anterior approach. In this study, we report the results of dual plating of fractures of the humeral shaft, with radiographic evidence and clinical analysis...

BACKGROUND: Shoulder arthroscopic arthrodesis is an uncommon and non-standardized procedure. Results are poorly evaluated. We describe the findings in 8 patients who underwent shoulder arthroscopic arthrodesis for brachial plexus injury. METHODS: The humeral head and glenoid were excised through standard arthroscopic portals. A Hoffmann external fixator and cannulated screws were used to stabilize the shoulder. Standard clinical assessment and radiographic evaluation were performed each month until bony fusion occurred...

BACKGROUND: Endoprosthetic reconstruction is widely applied for pathological fractures of the proximal humerus; however, functional impairment is usually unsatisfactory. The aims of the current study are to evaluate the reliability of interlocking intramedullary (IM) nailing with cement augmentation as a fixation method in proximal humeral lesions and to assess functional outcomes. METHODS: We reviewed 32 patients with pathological fractures of the proximal humerus who underwent interlocking IM nailing and cement augmentation...

BACKGROUND: Recurrence of glenohumeral dislocation after arthroscopic Bankart repair can be associated with a large osseous defect in the posterosuperior part of the humeral head. Our hypothesis is that remplissage is more effective to prevent recurrence of glenohumeral instability without a severe motion deficit. METHODS: Engaging Hill-Sachs lesions were observed in 48 of 737 patients (6.5%). Twenty-four patients underwent arthroscopic Bankart repair combined with remplissage (group I) and the other 24 patients underwent arthroscopic Bankart repair alone (group II)...
