Outcomes of ulna shortening osteotomy: a cohort analysis of 106 patients

Background Ulna shortening osteotomy (USO) for ulnar impaction syndrome (UIS) aims to improve pain and function by unloading the ulnar carpus. Previous studies often lack validated patient-reported outcomes or have small sample sizes. The primary objective of this study was to investigate patient-reported pain and hand function at 12 months after USO for UIS. Secondary objectives were to investigate the active range of motion, grip strength, complications, and whether outcomes differed based on etiology. Materials and methods We report on 106 patients with UIS who received USO between 2012 and 2019. In 44 of these patients, USO was performed secondary to distal radius fracture. Pain and function were measured with the Patient Rated Wrist/Hand Evaluation (PRWHE) before surgery and at 3 and 12 months after surgery. Active range of motion and grip strength were measured before surgery and at 3 and 12 months after surgery. Complications were scored using the International Consortium for Health Outcome Measurement Complications in Hand and Wrist conditions (ICHAW) tool. Results The PRWHE total score improved from a mean of 64 (SD = 18) before surgery to 40 (22) at 3 months and 32 (23) at 12 months after surgery (P < 0.001; effect size Cohen’s d = −1.4). There was no difference in the improvement in PRWHE total score (P = 0.99) based on etiology. Also, no clinically relevant changes in the active range of motion were measured. Independent of etiology, mean grip strength improved from 24 (11) before surgery to 30 (12) at 12 months (P = 0.001). Sixty-four percent of patients experienced at least one complication, ranging from minor to severe. Of the 80 complications in total, 50 patients (47%) had complaints of hardware irritation, of which 34 (32%) had their hardware removed. Six patients (6%) needed refixation because of nonunion. Conclusion We found beneficial outcomes in patients with UIS that underwent USO, although there was a large variance in the outcome and a relatively high number of complications (which includes plate removals). Results of this study may be used in preoperative counseling and shared decision-making when considering USO. Level of evidence Therapeutic III.

Correlation between hamstring tightness and time duration of disease in knee osteoarthritis: an observational cross-sectional study.

Background: Osteoarthritis (OA) is gradually developing articular diseases that originate in the cartilage and affects the underlying bone, soft tissues as well as synovial fluid. OA usually occurs late in life and mainly it affects the hand and large weight-bearing joints such as the knee and hip. The knee joint is largely affected due to its weight-bearing nature. In many studies, this functional loss is related to muscular weakness caused by OA in particular the quadriceps and hamstring muscles. Flexibility is the ability of a muscle to lengthen and allow one joint [or more than one joint in a series] to move through a range of motion. The hamstring muscle group have tendency to shorten and the tightening results in increased patello-femoral compressive force, which may eventually lead to patello-femoral syndrome often associated with osteoarthritis. Method: Seventeen patients with knee osteoarthritis matched with the inclusion criteria were included in the study. Sit and Reach test was used to evaluate the hamstring tightness. Goniometer was used to evaluate knee active range of motion Spearman’s correlation was used to determine the relationship between hamstring tightness and duration of disease in knee osteoarthritis. Result: The present study found significant inverse correlation (r = -0.07) between hamstring tightness and duration of disease such that the hamstring flexibility decreases with increase in the duration of knee osteoarthritis. However, the correlation between duration of disease and knee active range of motion was negligible (r = 0.25). Conclusion: The results states that hamstring tightness and duration of the disease in knee osteoarthritis are correlated. Further research is indicated with a larger sample size. Keywords: Knee osteoarthritis, hamstring tightness, osteoarthritis.

The evaluation and management of neonatal brachial plexus palsy

Neonatal brachial plexus palsy presents at birth and can be a debilitating condition with long-term consequences. Presentation at birth depends on the extent of nerve injury, and can vary from transient weakness to global paresis, with active range of motion affected. Serial clinical examination after birth and during the neonatal period (first month of life) is crucial to assess recovery and predicts long-term outcomes. This position statement guides the evaluation of neonates for risk factors at birth, early referral to a multidisciplinary specialized team, and ongoing communication between community providers and specialists to optimize childhood outcomes.

Prospective Evaluation of Low-Dose External Beam Radiotherapy (LD-EBRT) for Painful Trapeziometacarpal Osteoarthritis (Rhizarthrosis) on Pain, Function, and Quality of Life to Calculate the Required Number of Patients for a Prospective Randomized Study

Background: Retrospective studies have described the effectiveness of low-dose radiotherapy (LD-EBRT) in painful arthrosis of small finger joints, but two recent prospective studies have yielded ambiguous results. To generate accurate data for the planning of a trial, we conducted a prospective, monocentric, observational study to describe the effects of LD-EBRT as precisely as possible. Methods: Twenty-five consecutive patients with symptomatic trapeziometacarpal (TMC) arthrosis were irradiated with 6 × 0.5 Gy. Before, 3, and 12 months after LD-EBRT, we assessed subjective endpoints (modified “von-Pannewitz score”, 10-point visual analogue scale (VAS), “patient-rated wrist evaluation” (PRWE)), and objective measurements (“active range of motion” (AROM), Kapandji index, grip strength, pinch grip). Results: At 3/12 months, 80%/57% reported partial and 4%/18% complete remission according to the “von-Pannewitz” score. VAS “overall pain” significantly decreased from a median of seven (IQR 4) at baseline to three (IQR 6; p = 0.046) and to two (IQR 2; p = 0.013). Similar results were obtained for VAS “pain during exercise”, VAS “pain during daytime”, and VAS “function”. “PRWE overall score” was reduced from 0.5 at baseline (SD 0.19) to 0.36 (SD 0.24, p = 0.05) and to 0.27 (SD 0.18, p = 0.0009). We found no improvements of the objective endpoints (AROM, Kapandji, grip strength) except for flexion, which increased from 64° (SD 12°) at baseline to 73° (SD 9.7°, p = 0.046) at 12 months. Conclusions: We recommend the PRWE score as a useful endpoint for further studies for this indication. To prove a 15% superiority over sham irradiation, we calculated that 750 patients need to be prospectively randomized.

Reversed shoulder arthroplasty in treatment of proximal humeral fractures – early results in Department of Orthopaedics, Traumatology and Oncology, Regional Hospital in Torun, Poland

Introduction. Proximal humeral fractures (PHF) are a frequent finding, and still growing part of it needs to be treated operatively. Extending life expectancy, increasing percentage of osteoporotic fractures and progressive patients’ demand force surgeons to seek the best solutions of treating complex fractures. Just some teen years ago older patients who suffered a severe PHF were doomed to shoulder dysfunction. Today we can offer them a reversed shoulder arthroplasty (RSA) Purpose. The aim of the paper was a clinical evaluation of the patients who were treated with RSA in a Regional Hospital. Material and Methods. In years 2017-2021 in our department there were performed 41 RSAs and 5 TSAa (total anatomic shoulder arthroplasty). Earlier in 2010-2017 we performed 26 hemiarthroplasties. The procedures were done via delto-pectoral approach. The implant used were Aequalis Reversed Fracture (Tornier) and SMR (Lima). Results. The patients were evaluated in a simplified manner after 6 months postop. Functional active range of motion and VAS score were noted. Conclusions. In our department RSA is a well adopted method of treating complex PHFs, especially in elderly patients, and it yields overall good results and great percentage of satisfied patients.

Synthetic Mesh Reconstruction of Chronic, Native Quadriceps Tendon Disruptions following Failed Primary Repair

Case. Two patients presented with chronic knee extensor mechanism disruption after failed primary repairs. Both patients had minimal ambulatory knee function prior to surgical intervention and were treated with a synthetic mesh reconstruction of their extensor mechanism. Our technique has been modified from previously described techniques used in revision knee arthroplasty. At the one-year follow-up, both patients had improvement in their active range of motion and had returned to their previous activity. Conclusion. Synthetic mesh reconstruction of chronic extensor mechanism disruption is a viable technique that can be utilized as salvage for the persistently dysfunctional native knee.

The use of online video consultations in the aftercare of orthopedic patients: a prospective case-control study

Background Video consultations have proven to be an efficient source of support for patient-doctor interactions and have become increasingly used in orthopedics, especially during the COVID-19 pandemic. This study analyzed both patients’ and doctors’ acceptance of an orthopedic telemedical consultation (OTC) and compared the results of OTC examinations to the results of live consultation (LC) to identify discrepancies. Methods The study was carried out in an orthopedic department of a German hospital between 2019 and 2020. After written informed consent was obtained, patients voluntarily presented for follow-up by OTC and LC. The experience with and attitudes toward OTC among both patients and doctors was evaluated (using Likert scale-scored and open questions, 26 to 28 items). The results of the OTC and LC examinations were compared using a 12-item checklist. The data were analyzed by quantitative and qualitative statistics. Results A total of 53 patients were included, each of whom completed an OTC and an LC. The OTC was rated as pleasant, and the experience was rated as very satisfying (average rating on a 5-point Likert scale, with 1 indicating strong agreement: doctors: 1.2; patients: 1.3). Various technical and organizational challenges were identified. Compared to LC, OTC showed no significant differences in patient history or in inspection, palpation, or active range of motion results. Only for the functional or passive joint assessment did LC show significantly higher suitability (p < 0.05) than OTC. Recommendations for further procedures did not differ significantly between OTC and LC. Conclusions Because of the high acceptance and the objective benefits of OTC and the similarity of clinical results with LC, OTC is recommendable for orthopedic follow-up examinations. To better assess joint functionality, meaningful digital alternatives for established examination methods should be further investigated.

Pseudoparalysis and pseudoparesis of the shoulder

Background Clinical presentation of massive rotator cuff tears range from pain to loss of active range of motion. Pseudoparalysis and pseudoparesis are defined inconsistently in the literature, but both include limited active with maintained passive range of motion. Objective This article aims to provide a consistent definition of pseudoparalysis and pseudoparesis of the shoulder and show structural and biomechanical differences between these two types of rotator cuff tear with their implications for treatment. Methods A literature review including key and basic papers discussing clinical symptoms, biomechanical differences, and their impact on therapeutic options for pseudoparalysis and pseudoparesis was performed. Results Biomechanically, structural differences between pseudoparalysis (active scapular plane abduction <45°) and pseudoparesis (active scapular plane abduction 45–90°) exist. For massive posterosuperior rotator cuff tears, the integrity of the inferior subscapularis tendon is the most predictive factor for active humeral elevation. Patients with pseudoparalysis have a higher grade of subscapularis tendon involvement (>50%) and fatty infiltration of the subscapularis muscle. Treatment options depend on the acuteness and repairability of the tear. Rotator cuff repair can reliably reverse the active loss of active range of motion in acute and reparable rotator cuff tears. In chronic and irreparable cases reverse total shoulder arthroplasty is the most reliable treatment option in elderly patients. Conclusion The most concise definition of pseudoparalysis is a massive rotator cuff tear that leads to limited active (<45° shoulder elevation) with free passive range of motion in the absence of neurologic deficits as the reason for loss of active elevation. The integrity of the subscapularis tendon is the most important difference between a pseudoparalytic and pseudoparetic (active shoulder elevation 45–90°) shoulder. Decision-making for surgical options depends more on reparability of the tendon tear and patient age than on differentiation between pseudoparalysis and pseudoparesis.
