Hook plate fixation of Neer type II distal clavicle fractures results in satisfactory patient-reported outcomes but complications and revisions are high.

Background: Surgical treatment of distal clavicle fractures Neer type II is challenging. A gold standard has not yet been established, thus various surgical procedures have been described. The purpose of this study is to report the radiological and clinical outcomes using hook plate fixation in Neer type II distal clavicle fractures.

Correlation of Acromial Morphology With Risk and Direction of Shoulder Instability: An MRI Study.

Background: The influence of bony morphology on the development of posterior shoulder instability is not well known.

Purpose: To determine if acromial morphology, as measured on magnetic resonance imaging (MRI), is associated with posterior or anterior shoulder instability.

Design: Cross-sectional study; Level of evidence, 3.

High return to sport rate and good patient-reported outcomes in recreational athletes following simple elbow dislocations.

Background: The purpose of this study was to investigate outcomes and return to sport metrics in recreational athletes who suffered simple elbow dislocations and were treated operatively or nonoperatively.

Methods: The study included patients between the ages of 16 and 65 who were recreational athletes and had experienced a simple elbow dislocation, with at least 2 years having passed since the injury. Patient-reported outcomes including Mayo Elbow Performance Score (MEPS), Subjective Elbow Value (SEV), Oxford Elbow Score (OES) and Visual Analog Scale (VAS) were collected.

[Plate-assisted bone segment transport for bone defects of the lower extremities : Possibilities and limitations of treatment].

Large bone defects of the lower extremities are challenging for both patients and the treating orthopedic surgeons. The treatment is determined by the size and location of the defect; however, patient-specific factors, such as the soft tissue situation and the presence of systemic comorbidities must be taken into consideration in the treatment strategy. Osteodistraction is an excellent technique especially for large bone defects exceeding 3 cm; however, it is time-consuming and required external fixation prior to the development of motorized distraction nails.

Improvement in long head of biceps function and lower rate of biceps deformities after subpectoral tenodesis with cortical button and interference screw vs. arthroscopic tenotomy: a 4-year follow-up.

Background: This study aimed to evaluate clinical, cosmetic, and strength midterm outcomes in arthroscopic biceps tenotomy and subpectoral biceps tenodesis using bicortical endobutton and interference screw.

Methods: In this retrospective study, inclusion criteria were long head of the biceps (LHB) pathologies treated either with tenotomy or an additional tenodesis. Postoperative assessment included Long Head of Biceps Score (LHBS), age-adjusted Constant-Murley Score, and Subjective Shoulder Value.

Does the Interval Slide Procedure Reduce Supraspinatus Tendon Repair Tension?: A Biomechanical Cadaveric Study.

Background: The benefits of the interval slide (IS) procedure in retracted rotator cuff tears remain controversial.

Purpose: The purpose was to evaluate the effect of the IS procedure on repair tension (RT). It was hypothesized that the IS procedure (anterior IS [AIS], posterior IS [PIS], and intra-articular capsular release [CR]) would reduce the RT of a supraspinatus tendon.

No difference in mid-term outcome after superior vs. anteroinferior plate position for displaced midshaft clavicle fractures.

To compare outcomes, complications, revisions, and rates of implant removal of superior compared to anteroinferior plating in displaced midshaft clavicle fractures at mid-term follow-up. We retrospectively reviewed 79 patients who underwent operative treatment for displaced midshaft clavicle fractures (Group A: 28 patients with superior plating; Group B: 51 patients with anteroinferior plating) that were at least 2 years postoperatively. Adjusted Constant Score (aCS), Visual Analog Scale (VAS), and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score were compared.

More Adverse Events after Osteosyntheses Compared to Arthroplasty in Geriatric Proximal Humeral Fractures Involving Anatomical Neck.

The purpose of this study was to compare adverse events and clinical outcomes of geriatric proximal humerus fractures (PHF) involving the anatomical neck (type C according to AO classification) treated with open reduction and internal fixation (ORIF) using locking plate vs. arthroplasty. In this retrospective cohort study, geriatric patients (>64 years) who underwent operative treatment using ORIF or arthroplasty for type C PHFs were included.

Long-term outcome and survival rate of monopolar radial head replacement.

Background: The purposes of this study were (1) to report functional outcomes; (2) to assess complications, revisions, and survival rate; and (3) to assess differences in functional outcomes between removed and retained radial head arthroplasties (RHAs), early and delayed treatment, and type of RHA used at long-term follow-up after monopolar RHA for unreconstructible radial head fractures or their sequelae.

Methods: Seventy-eight patients (mean age, 59.2 years) who were at least 6 years postoperatively after monopolar RHA for unreconstructible RHFs or their sequelae were included.

Robot-assisted training after proximal humeral fracture: A randomised controlled multicentre intervention trial.

Objective: To examine whether robotic-assisted training as a supplement to usual therapy is safe, acceptable and improves function and patient reported outcome after proximal humeral fractures (PHF).

Design: Multicentre, assessor-blinded, randomised controlled prospective trial.

Setting: Three different rehabilitation hospitals in Germany.

Biomechanical significance of the collateral ligaments in transolecranon fracture-dislocations.

Background: It is widely accepted that transolecranon fracture-dislocations are not associated with collateral ligament disruption. The aim of the present study was to investigate the significance of the collateral ligaments in transolecranon fractures.

Methods: Twenty cadaveric elbows with a mean age of 46.

Conversion of Failed Proximal Long Head of the Biceps Tenodesis to Distal Subpectoral Tenodesis: Outcomes in an Active Population.

Purpose: To assess failure rates and patient reported outcomes following revision of failed proximal long head of the biceps (LHB) tenodesis.

Methods: Patients from an active-military population who underwent revision proximal (suprapectoral) to distal (subpectoral) LHB tenodesis were prospectively enrolled. Patients were included if they were between the ages of 16 and 60 years presenting after a previous biceps tenodesis with mechanical failure and clinical failure, defined as Single Assessment Numeric Evaluation (SANE) or American Shoulder and Elbow Surgeons (ASES) <70.

[Reconstruction of a fracture of the posterior acetabular wall with Pipkin fracture and lesion of the sciatic nerve after dorsal hip dislocation].

A 50-year-old male suffered a crash landing while paragliding and sustained a posterior dislocation of the hip with a Pipkin fracture type 4 (fracture of the posterior acetabular wall and Pipkin fracture type 2) and a lesion of the sciatic nerve. After primary treatment in an external hospital, the patient was transferred to this hospital 4 days following the trauma. An operative stabilization of the acetabular fracture and the Pipkin fracture was performed using a trochanter flip osteotomy.

Inter-rater reliability, sensitivity to change and responsiveness of the orthopaedic Wolf-Motor-Function-Test as functional capacity measure before and after rehabilitation in patients with proximal humeral fractures.

Background: The incidence of proximal humeral fractures (PHF) increased by more than 30% over the last decade, which is accompanied by an increased number of operations. However, the evidence on operative vs. non-operative treatment and post-operative treatments is limited and mostly based on expert opinion.

Analysis of cervical spine immobilization during patient transport in emergency medical services.

Purpose: It remains controversial how to immobilize the cervical spine (CS) in trauma patients. Therefore, we analyzed different CS immobilization techniques during prehospital patient transport.

Methods: In this explorative, biomechanical analysis of immobilization techniques conducted in a standardized setting, we recorded CS motion during patient transport using a wireless human motion tracker on a volunteer.
