Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Lateralization01:28

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Summary

This case report highlights a rare congenital anomaly: a 6-year-old child with central deficiency in both the hand and foot. This rare occurrence underscores the importance of recognizing syndromic presentations of congenital malformations.

Area of Science:

  • Orthopedics
  • Medical Genetics
  • Developmental Biology

Background:

  • Congenital anomalies of the hand are significant malformations impacting function and cosmesis.
  • Central deficiency, or cleft hand, is a relatively uncommon congenital hand anomaly.
  • Associated anomalies can occur, necessitating comprehensive evaluation.

Observation:

  • A 6-year-old child presented with congenital anomalies.
  • The child was born of a non-consanguineous marriage.
  • The patient exhibited congenital central deficiency of the ipsilateral hand and foot.

Findings:

  • The case details a rare co-occurrence of bilateral central deficiency (cleft hand and cleft foot).
  • This presentation is significantly rarer than isolated cleft hand or foot anomalies.
  • The anomaly was present from birth in an otherwise healthy child from a non-consanguineous union.

Implications:

  • This case emphasizes the importance of recognizing rare congenital malformations and their potential syndromic associations.
  • Early identification and management are crucial for functional and cosmetic outcomes in limb anomalies.
  • Further research into the genetic and developmental pathways of limb malformations is warranted.
