In hammer toe correction by means of digital fusion, fixation so that the bone can unite while maintaining appropriate realignment can be a challenge. Metal fixation pins can be associated with many problems and potential complications. The author presents a method of rigid internal fixation using 2.4-mm-diameter pins fashioned out of freeze-dried allogeneic cortical bone. These devices avoid most of the risks of metal pins. Proximal interphalangeal joint arthrodesis using cortical bone pins was performed on 26 toes in 18 patients with very few complications. The author concludes that use of cortical bone pins can yield successful results in most cases. The outcomes of the fusions can be further enhanced by using flexor digitorum longus tendon transfer.

Correction of claw or hammer toe deformity can be achieved using various techniques, including proximal interphalangeal joint arthrodesis (PIPJA), flexor digitorum longus tendon transfer (FDLT), and flexor digitorum brevis transfer. PIPJA is the oldest technique, but is associated with significant complications (infection, fracture, delayed union, and nonunion). FDLT eliminates the deformity, but leads to loss of stability during gait. Flexor digitorum brevis tendon transfer (FDBT) seems to be the best surgical alternative, but it is a recent technique with still limited results. In this work, these three techniques have been analyzed by means of the finite-element method and a comparative analysis was done with the aim of extracting advantages and drawbacks. The results show that the best technique for reducing dorsal displacement of the proximal phalanx is PIPJA (2.28 mm versus 2.73 mm for FDLT, and 3.31 mm for FDBT). However, the best technique for reducing stresses on phalanges is FDLT or FDBT (a reduction of approximately 35% regarding the pathologic case versus the increase of 7% for the PIPJA in tensile stresses, and a reduction of approximately 40% versus 25% for the PIPJA in compression stresses). Moreover, the distribution of stresses in the entire phalanx is different for the PIPJA case. These facts could cause problems for patients, in particular, those with pain in the surgical toe.

Congenital swan neck deformities in seven fingers of two patients were treated by transfer of the flexor digitorum superficialis tendon to a tendon graft which was attached the extensor aponeurosis over the middle phalanx. The tendon transfer is protected for at least 2 months by a modified Murphy splint.

We reviewed 20 cases of chronic dorsal fracture-dislocation of the proximal interphalangeal joint, with a mean follow-up period of 74 months. In patients without comminuted palmar fragments, open reduction and internal fixation or osteotomy of the malunited fragment provided good results. In treating patients with damaged articular cartilage or with comminuted palmar fragments by palmar plate arthroplasty, poor results were obtained because of secondary osteoarthritic changes.

Thirty-six patients were treated for 38 phalangeal fractures using 1.5 mm and 2 mm A. O. screws. Plates were not used in the fingers. Oblique fractures of the condyles, shafts or bases of the proximal or middle phalanges were treated by internal fixation because of instability, displacement or rotation. 40% of fractures had associated skin wounds, were comminuted or had damage to the extensor mechanism. The mean duration of post-operative immobilization was 9 days and the mean time off work was 6 weeks. Total active movement in the involved ray was 220 degrees or greater in 24 cases, 180 degrees to 215 degrees in eight cases, and less than 180 degrees in two patients at follow up. The patients were reviewed between three and 54 months after treatment and the mean duration of follow up was 24 months. The most frequent complication was 10 degrees to 30 degrees of flexion deformity of the proximal interphalangeal joint after internal fixation of condylar fractures. Results were satisfactory in 90% of cases.
