Genesis 2: 21-22 - Why God Chose Adam's Rib to make Eve

And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.

Cranioplasty using a synthetic material is less than ideal, especially if there is a history of infection at the defect site. Split-rib cranioplasty is a practical approach even in patients with a positive history of infection at or around the defect. We briefly review the historical backround of split-rib cranioplasty and report our experience with this procedure in 12 patients. Forty-two pieces of rib, with an average length of 13 cm, were used for reconstruction. We had only 1 complication - a pneumothorax following removal of the rib graft. The follow-up period ranged from three to thirty-six months. All patients had complete regeneration of the donor rib and solid protection of the brain.

Morphological study of rib regeneration following costectomy in adolescent idiopathic scoliosis

Abstract

This is a prospective observational study comparing cases with retrospective controls. The aim of the study is to compare rib regeneration with a scaffold placed intra-periosteally against no scaffold, after costectomy in adolescent idiopathic scoliosis. A prospective study was conducted at Amrita Institute of Medical Sciences on 16 consecutive patients (51 ribs) with adolescent idiopathic scoliosis who underwent costectomy and application of gel foam in the rib bed as a scaffold. These patients were compared with a retrospective group of 15 patients (33 ribs) who did not have the scaffold. All prospective and retrospective patients were followed up for a minimum period of 6 months and were analyzed radiographically for rib regeneration and morphology. A classification system was devised to include all possible morphologies of regenerate. The resulting data, when analyzed showed that majority of ribs re-grew to normal morphology in 3–6 months in the trial group. In comparison the regeneration in the retrospective controls was slower and poorer in quality. Ribs treated by placement of gel foam scaffold in the bed regenerate to a near normal radiological profile within 6 months of costectomy compared to a slower regeneration in those without gel foam scaffold.

And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.

This particular scripture is quite an interesting one. Its because of this scripture that some Christians that take it literally believe men have a missing rib. However, that view doesn't hold up to scrutiny at all as we of course know that we have all 24 bones intact. However, what is not apparently widely known is that human ribs can regenerate like a salamanders tail as long as the periosteum, the membrane surrounding the rib, is left intact as shown in the links below. Based on the way the verse was written, I've concluded that the first surgery ever performed was done by God.
