Outcomes of footprint medialization and bone marrow stimulation in chronic retracted rotator cuff tears.

Background: This study compared the clinical and radiological outcomes of chronic retracted rotator cuff tears where complete footprint coverage cannot be achieved, using two treatments: footprint medialization with bone marrow stimulation and conventional incomplete repair.

Methods: This retrospective study included 87 patients who underwent arthroscopic rotator cuff repair with incomplete footprint coverage. The included patients were divided into group 1 (54 patients with footprint medialization and bone marrow stimulation) and group 2 (33 patients with conventional repair).

Mid-Thoracic Vertebral Compression Fracture after Mini-Trampoline Exercise: A Case Series of Seven Patients.

: Home-based training exercise gained popularity during the coronavirus disease 2019 pandemic era. Mini-trampoline exercise (MTE) is a home-based exercise that utilizes rebound force generated from the trampoline net and the motion of the joints of the lower extremities. It is known to be beneficial for improving postural balance, stability, muscle strength and coordination, bone strength, and overall health.

Percutaneous transpedicular intracorporeal cage grafting for Kümmell disease.

Background: Osteonecrosis with progressive collapse and segmental kyphosis can lead to intersegmental instability in some osteoporotic vertebral compression fractures (OVCFs). These conditions are known as Kümmell's disease and often require anterior column reconstruction in elderly patients.

Methods: We attempted anterior column reconstruction by percutaneous transpedicular intracorporeal cage grafting (PTICG) with short-segment pedicle screw fixation and described the steps, with discussions on the surgical indications and pros and cons.

Biportal Endoscopic Technique for Transforaminal Lumbar Interbody Fusion: Review of Current Research.

Background: There are many types of minimally invasive lumbar interbody fusion procedures. Among them is the recently introduced biportal endoscopic lumbar interbody fusion surgery. Biportal endoscopic transforaminal lumbar interbody fusion (TLIF) might combine the advantages of minimally invasive TLIF and endoscopic spine approaches.

Evaluation of Muscular Atrophy and Fatty Infiltration Using Time-zero Magnetic Resonance Imaging as Baseline Data, After Rotator Cuff Repair.

Background: This study evaluated postoperative changes in the supraspinatus from time-zero to 6 months, using magnetic resonance imaging (MRI). We hypothesized that restoration of the musculotendinous unit of the rotator cuff by tendon repair immediately improves the rotator cuff muscle status, and maintains it months after surgery.

Methods: Totally, 76 patients (29 men, 47 women) with rotator cuff tears involving the supraspinatus tendon who underwent arthroscopic rotator cuff repairs were examined.
