Derotation osteotomy of the forearm in management of paralytic supination deformity.

Ten children with supination deformity of the forearm due to obstetric paralysis were treated by pronation osteotomy of the radius and ulna. In two patients release of the interosseous membrane was added. The main achievement of the operation was an improved position of rest, which rendered a mechanical advantage for the basic function of the hand in grasping medium-sized objects. Preliminary results of three other patients who recently underwent rerouting of the biceps tendon concurrently or following the osteotomy are encouraging. One patient who had both procedures underwent rerouting of the biceps, which resulted in a gain of 135 degrees of active pronation.

Surgical treatment of the clasped thumb.

We report a series of 12 patients (19 hands) with clasped thumb who underwent surgical treatment. The series is divided into three groups. In the first group, the prominent pathological feature was hypoplasia of the extensor tendons which was treated by tendon transfer. The second group, the arthrogryphotic type, had contracture of the intrinsic muscles of the thumb and shortening of the skin; these needed mainly release operations. In only three hands out of nine was tendon transfer performed. The third group was defined by a combination of skeletal, muscular and tendon hypoplasia. Instability of the M.P. joint and adduction contracture of the first ray were found in all hands of this group. The adduction deformity was corrected by skin-plasty of the first web and the extension was improved by tendon transfers. Only one case needed stabilisation of the M.P. joint. The final results were related to the extent of the contractures and to the age of the patient when treatment started.

Calcinosis circumscripta: indications for surgery.

Five patients with calcinosis circumscripta were treated, four of them surgically. The indications for surgery included painful lumps, recurrent infection of the calcified masses, secreting ulcers, functional disorders, severe esthetic problems, and pressure on nerves. One patient showed permanent improvement; four gained temporary relief.

The lumbosacral ligament (LSL), with special emphasis on the "lumbosacral tunnel" and the entrapment of the 5th lumbar nerve.

The lumbo-sacral ligament (LSL) was studied in 42 specimens. It extends from the L5 vertebra to the ala of the sacrum and forms, with the structures to which it is attached, an osteofibrotic tunnel as an extension of the intervertebral foramen. The 5th lumbar nerve root passes through the tunnel over the ala of the sacrum and behind the LSL. A branch of the 4th lumbar nerve root passes in front of the LSL to join the 5th below the ligament to form the lumbo-sacral trunk. The sympathetic ramus communicans to the L5 root always penetrates the LSL at its superior border and reaches the nerve inside the tunnel. Branches of the ilio-lumbar vessels accompany the L5 root. Large osteophytes on the inferior border of L5 and tightness of the LSL were often found to cause entrapment and compression of the L5 nerve root against the ala of the sacrum.
