Patellar Tendon Rupture During Postoperative Physiotherapy for Crouch Gait: A Case Report.

INTRODUCTION: A 14-year-old adolescent girl with spastic diplegic cerebral palsy underwent bilateral distal femur extension osteotomy and patellar tendon plication. Two and a half months after surgery, during physiotherapy, she sustained mid-substance tear of the left patellar tendon. The girl was successfully managed with patellar tendon repair and augmentation with tensor fascia lata autograft. CONCLUSION: Patellar tendon rupture during rehabilitative physiotherapy after patellar tendon plication surgery is rare. Postoperative protocols in patients with cerebral palsy are crucial and should progress gradually to improve knee range of motion. This report highlights that patellar tendon repair with fascia lata augmentation yields good outcome.

Challenges in Management of Proximal Humerus Diaphyseal Fracture in a Patient with Brachial Plexus Birth Injury: A Case Report.

CASE: Two-and-a-half-month-old boy, a known case of brachial plexus birth injury, sustained proximal humeral diaphyseal fracture. Fracture healed in varus malunion and failed to remodel subsequently. Challenges were faced in the course of the management because of progression of the deformity. Finally, the fracture united after rigid internal fixation performed at 2.5 years. CONCLUSION: Neuromuscular imbalance can lead to angular deformity at fracture site and cause unpredictable remodeling, as in our case. Conservative management may fail to achieve union with satisfactory alignment. Rigid internal fixation should be considered in such cases to achieve union.

Brachial Plexus Birth Injury due to Proximal Humeral Physeal Separation: A Case Report.

CASE: A 9-day-old male neonate presented with swelling over his left shoulder and reduced movements of the left upper extremity since birth. Radiographs raised a suspicion of a shoulder dislocation. Ultrasonography confirmed the diagnosis of proximal humeral physeal separation. Magnetic resonance imaging (MRI) revealed edema of the infraclavicular part of the brachial plexus. Conservative management was followed, and the injury remodeled completely at 2 years. CONCLUSION: Neonatal proximal humeral physeal separation poses a diagnostic challenge. Ultrasonography is helpful for diagnosis. MRI is indicated when concurrent brachial plexus birth injury is suspected. Conservative management yields good outcome in the absence of entrapped nerves and tendons.

Clinical Diagnosis of the Infantile Shoulder Subluxation in Residual Brachial Plexus Birth Injury and Its Correlation With Ultrasound Diagnosis.

INTRODUCTION AND AIMS OF STUDY: Timely detection of shoulder subluxation in infants with brachial plexus birth injury (BPBI) is essential to prevent the progression of glenohumeral deformity. Shoulder ultrasonography (USG) is routinely used to detect an infantile subluxation/dislocation, but its use is limited because of the paucity of expert radiologists in developing countries. The aim of this study was to determine the clinical examination predictors to determine shoulder subluxation in patients with BPBI correlating with ultrasound confirmation. METHODS: We prospectively studied children who presented to our hospital between 2017 and 2021 diagnosed as brachial plexus birth injury. In patients developing internal rotation contracture of the shoulder, we looked for 3 standard clinical signs: reduced passive external rotation <60 degrees, deep anterior crease (DAC) and relatively short arm segment. Shoulder subluxation was defined as USG measurement of alpha angle>30 degrees and ossific nuclei of the humerus lying behind the dorsal scapular line. Sensitivity and specificity were used to assess their efficacy in clinical diagnosis of shoulder subluxation in different groups. The predicted probability of shoulder subluxation from each prediction rule was compared with actual distributions based on USG confirmation. RESULTS: Of the 58 BPBI infants who developed PER<60 degrees at the shoulder, 41 had USG confirmed shoulder subluxation. The 2 independent predictors of shoulder subluxation (PER<45 degrees and DAC) were identified in the current patient population based on data analysis. The presence of short arm segment is a very specific marker of shoulder subluxation but not sensitive. The predicted probability of shoulder subluxation from the prediction rule combining all the 3 markers were similar to the actual distributions in the current patient population. CONCLUSIONS: PER<45 degrees and presence of deep anterior crease are clinical markers indicating shoulder dislocation in patients with BPBI developing reduced external rotation at the shoulder. On the basis of the proposed clinical diagnosis algorithm, the above markers along with the selective use of USG can help in early detection and treatment of infantile shoulder dislocation.
