The intermetatarsophalangeal bursa--its significance in Morton's metatarsalgia.

The intermetatarsophalangeal bursa was investigated by dissection, radiography and injection. In the web spaces between the second and third and the third and fourth digits the bursa lies superior to the transverse metatarsal ligament but projects distally to it, closely applied to the neurovascular bundle. Tissue from the web spaces of patients with classical Morton's metatarsalgia often shows lymphocytic infiltration, with additional fibrinoid necrosis of the bursal wall. It is suggested that inflammatory changes in this bursa could account for the pathological and histological findings in this condition. The bursa in the most lateral web space does not extend beyond the ligament and is not in contact with the neurovascular bundle, which may explain the rarity of symptoms in this space.

Perichondrial arthroplasty. A clinical study in twenty-six patients.

26 patients with painful and/or rigid small joints of the extremities have undergone surgery by a new arthroplasty method, utilizing the cartilaginous potential of the perichondrium demonstrated earlier in animal experiments. Perichondrium from the rib has been grafted to the articular surfaces of the affected joint after removal of the remaining ordinary articular cartilage. In 12 cases the joint disease was a sequela after trauma--either fracture involving the joint surfaces, or an open joint injury complicated by a purulent arthritis. In 6 cases there was an idiopathic degenerative joint disease and in 5 the arthritis was of rheumatic origin. In a further 3 cases the indications for operation were various. The follow-up period varied between 3 and 41 months. 13 patients classified as excellent regained range of motion and power and had no pain either at rest or at work. In 3 cases range of motion and power improved, but there was still some pain in the affected joint at work. Ten cases were not improved by the perichondrial arthroplasty and possible reasons for this are discussed. The results indicate that it is possible to restore joint function using free autologous perichondrial grafts from the rib.

[Arthrodesis technique in post-traumatic foot disorders].

Surgical arthrodesis procedures are effective in stabilizing painful joints in the foot. Joints most suitable for arthrodesis are: the hallux joints, midfoot, and hindfoot joints. The use of internal fixation is recommended whenever possible to ensure a successful fusion. However, surgical technique is most important as is the final position of the fused joints.

[Progression towards dislocations of foot bone lesions in leprosy].

From a series of 211 tarsal, medio-tarsal and metatarso-phalangeal dislocations, the authors, after having recalled the lesion mechanism, adopted a classification and gave a place to preventive conservative surgery in 52 cases. The early forms can have early limited arthrodesia. The developed lesions present indications of arthrodesia--isolated reconstruction or associated to spongy or cortico-spongy bone grafts. The late forms impose amputation even when the forefoot seems of good bone quality because the metatarsal-phalangial stiffness is the cause for the failure of the Wladimiroff-Mickulicz interventions.

Radiographic features of gout.

Hyperuricemia is the hallmark of gout. Deposition of monosodium urate crystals in the joints and periarticular soft tissues can lead to arthritic changes. Radiographic features include periarticular soft tissue swelling, "punched-out" bony erosions and joint space narrowing. Although gout has a predilection for the first metatarsophalangeal joint, it may also affect the feet, hands, wrists, elbows and knees.
