“…For instance, scholars have achieved positive outcomes by using the Ilizarov microfixator to extend amputation stumps of distal phalanges measuring less than 10 mm 12 . Similarly, the Mini–Ring Ilizarov Device has been employed to extend the thumb and metacarpal bone, with all patients experiencing satisfactory results during follow-up 13 . Currently, among all wrist bones, there are only reports on the application of this technique in treating scaphoid fractures 14 , 15 .…”

This study aims to measure anatomical data of the capitate bone, develop an external fixator for treating late-stage osteonecrosis of lunate through Ilizarov technique, and evaluate its biomechanical performance. We selected eight wrist joint specimens to measure various parameters of the capitate bone, including its length, the distance from the junction of capitate head and body to the proximal end, as well as the width of its proximal head and distal body. Additionally, we measured these same indicators in 107 patients who had undergone wrist X-ray examination. Based on our measurements, we categorized the capitate bone into two groups and designed two types of capitate bone Ilizarov external fixator (CIEF) for it. Then, we compared it with the orthofix external fixator (OEF) through dynamic fatigue biomechanical experiments and pull-out resistance experiments. The results of the measurement revealed two categories of general patterns in the capitate bone. The first type maintains a consistent longitudinal axis between the proximal and distal ends. The second type is characterized by its proximal end being close to the radial side and its distal end being close to the ulnar side. In the dynamic tensile fatigue test, CIEF-A and CIEF-B had smaller maximum displacement values compared to the OEF (P < 0.05). In the anti-pull-out experiment, both CIEF-A and CIEF-B exhibited higher maximum pull-out force than the OEF (P < 0.05). CIFE is a treatment for advanced osteonecrosis of the lunate bone. It is specifically designed to align with the anatomical characteristics of the capitate bone, providing excellent biomechanical properties and a simple clinical procedure. However, additional clinical experiments are needed to confirm its effectiveness in the future.

Brachydactyly is a genetic condition leading to shortened or absent digits in hands or feet. It can occur independently or as part of syndromes. This case focuses on Brachydactyly type B, the rarest form. An 8-month-old from the Philippines was referred due to a missing third toe. Examination revealed a hypoplastic left third toe. X-rays confirmed the finding. Treatment options were discussed, including conservative therapy and follow up. Diagnosis involved history, examination, and imaging. Prenatal diagnosis is limited for isolated cases but useful for syndromic forms if a family mutation is known. Prognosis varies depending on the severity and associated syndromes. Currently there is no definitive treatment; management involves genetic counseling and therapy. Due to limited cases, Type B is underreported, highlighting the need for more research into its genetics.
