What You Should Know About Other Complications
Dorsal contracture can be a frustrating complication. It can occur when the surgeon has failed to address a more proximal etiology of the hammertoe such as metatarsophalangeal joint contracture. However, one may also see a dorsal contracture occur as a response to the body’s natural healing and scar contracture of a dorsally placed longitudinal incision.
Employing a medial longitudinal approach can avoid this complication. However, surgeons can often use scar contracture to their advantage — especially when dealing with mallet toe deformities — by making a transverse elliptical incision across the distal interphalangeal joint. In cases of postoperative dorsal contracture recalcitrant to conservative care such as massage or physical therapy, we find it helpful to manipulate the joint under anesthesia to mobilize the joint.
Floppy toes can result from excessive bony resection of a hammertoe. Patients often find this to be the most intolerable complication. They complain of discomfort, a feeling of uneasiness when putting on a sock and a feeling of insufficient function with ambulation. Employing more minimal resection intraoperatively, fusing the toe or utilizing an implant can prevent this complication. However, when floppy toes occur, it may be necessary to revise an existing implant, perform syndactylization or proceed with an amputation.
Vascular compromise is the most severe complication one may see with hammertoe correction. Ensuring a proper preoperative assessment of vascular integrity is obviously the most important preventive measure. Excessive dissection can be an additional cause of vascular compromise. Excessive straightening of the toe maintained by K-wires is another common etiology of vascular problems. Changing the position of the wire intraoperatively or removing the K-wire early in the postoperative period when indications are present can help this problem. However, when a vascular compromise occurs, one should wait for demarcation to occur before pursuing definitive procedures.
Hammertoe repairs offer predictable, gratifying outcomes for the surgeon and patient. When performing these procedures, ensuring proper preoperative planning and intraoperative and postoperative management can reduce the incidence of complications. However, when complications arise, surgeons must address them in a proper and timely fashion.
