The aim of this study was to develop and internally validate a prognostic nomogram to predict the probability of gaining a functional range of motion (ROM ≥ 120°) after open arthrolysis of the elbow in patients with post-traumatic stiffness of the elbow. We developed the Shanghai Prediction Model for Elbow Stiffness Surgical Outcome (SPESSO) based on a dataset of 551 patients who underwent open arthrolysis of the elbow in four institutions. Demographic and clinical characteristics were collected from medical records. The least absolute shrinkage and selection operator regression model was used to optimize the selection of relevant features. Multivariable logistic regression analysis was used to build the SPESSO. Its prediction performance was evaluated using the concordance index (C-index) and a calibration graph. Internal validation was conducted using bootstrapping validation.Aims
Methods
The aim of this study was to analyze the results of reverse shoulder
arthroplasty (RSA) in patients with type 1 sequelae of a fracture
of the proximal humerus in association with rotator cuff deficiency
or severe stiffness of the shoulder. A total of 38 patients were included: 28 women and ten men. Their
mean age at the time of arthroplasty was 73 years (54 to 91). Before
the RSA, 18 patients had been treated with open reduction and internal
fixation following a fracture. A total of 22 patients had a rotator
cuff tear and 11 had severe stiffness of the shoulder with < 0°
of external rotation. The mean follow-up was 4.3 years (1.5 to 10).
The Constant score and the range of movement of the shoulder were
recorded preoperatively and at final follow-up. Preoperatively, radiographs in two planes were performed, as
well as CT or arthro-CT scans; radiographs were also performed at
final follow-up.Aims
