Surgical Technique: Spike Translation: A New Modification in Step-Cut Osteotomy for Cubitus Varus Deformity
Clinical Orthopaedics and Related Research®, 2013Co-Authors: Ali Moradi, Ehsan Vahedi, Mohammad H. EbrahimzadehAbstract:Background Various methods of Osteotomy have been proposed for the treatment of cubitus varus. We designed a modification of the Step-Cut Osteotomy to achieve more correction of the deformity. We describe this new technique called spike translation Step-Cut Osteotomy and report the clinical and radiographic outcomes (deformity correction, ROM, function, Osteotomy healing, complications) in a series of patients treated for cubitus varus using this technique. Description of Technique The technique involves a kind of closing-wedge Osteotomy with a lateral spike to correct cubitus varus. To avoid lateral epicondyle prominence, the spike is translated medially and embedded in the proximal segment. Methods We treated 13 patients with cubitus varus using the new technique between 2005 and 2010. We compared preoperative and postoperative clinical and radiographic parameters (humerus-elbow-wrist angle, lateral prominence index, arc of elbow motion, DASH score) for all patients. Time to union was recorded. Postoperative evaluation was performed according to the modified criteria of Oppenheim et al. Minimum followup was 16 months (average, 27 months; range, 16–43 months). Results The average humerus-elbow-wrist angle improved from −26° to 11°. The mean lateral prominence index did not differ after correction of deformity compared with the normal side. By using our rehabilitation protocol, all patients regained preoperative arcs of elbow motion in a mean of 2.5 months (range, 1.50–3.50 months) postoperatively, and the mean union time was 1.65 months. According to the criteria of Oppenheim et al., there were 11 excellent and two good results. Conclusions Our spike translation Step-Cut Osteotomy with a larger contact surface of cancellous bone can be a reasonable alternative for correction of a cubitus varus deformity, with satisfactory deformity correction, reliable healing of Osteotomy, and low complication rates. Level of Evidence Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

modified step cut Osteotomy for metacarpal and phalangeal rotational deformity
Journal of Hand Surgery (European Volume), 2009Co-Authors: Andrew Jawa, Maura Zucchini, Guilio Lauri, Jesse B JupiterAbstract:Purpose Rotational deformity of metacarpal and phalangeal fractures can jeopardize normal hand function and cause aesthetic problems for patients. We have found the Z-cut metacarpal Osteotomy, initially described by Manktelow, to prove predictable and provide precise restoration of rotation and function. Therefore, we reviewed our experience with this technique. Methods The senior authors identified 12 patients treated with rotational Step-Cut osteotomies for digital rotatory deformities. The cases were reviewed retrospectively. Seven had metacarpal and five had phalangeal malunions. Results All 12 patients had correction of their deformities, obtained union of the Osteotomy, and maintained or improved their motion. There were no perioperative complications. Conclusions Metacarpal Step-Cut osteotomies are a technically simple and effective method for correction of digital rotational deformities resulting from fracture malunions. Unlike other types of osteotomies, this technique affords precise intraoperative control at the Osteotomy site, a large surface area for bony healing, and rigid fixation with early digital motion.

Long-Term Outcome of Step-Cut Ulnar Shortening Osteotomy for Ulnar Impaction Syndrome.
Journal of Bone and Joint Surgery American Volume, 2016Co-Authors: Loukia K. Papatheodorou, Mark E. Baratz, Sofia Bougioukli, Tyler Ruby, Robert W. Weiser, Dean G. SotereanosAbstract:Background: Extra-articular ulnar shortening Osteotomy is a common procedure for the surgical treatment of ulnar impaction syndrome. Several techniques for this Osteotomy have been developed to avoid the morbidity associated with a standard transverse Osteotomy. However, these techniques require special instrumentation and are expensive. The purpose of this study was to evaluate the outcome of Step-Cut ulnar shortening Osteotomy without special jigs for ulnar impaction syndrome. Methods: A retrospective study of 164 consecutive patients who underwent Step-Cut ulnar shortening Osteotomy between 2000 and 2010 was performed. The long arm of the Step-Cut Osteotomy was oriented in the coronal plane parallel to the long axis of the ulna. The short arms of the Osteotomy were perpendicular to the long axis in the axial plane. Fixation was performed with a palmar 3.5-mm standard neutralization plate and a lag screw. The goal of the Osteotomy was to reduce ulnar variance, which was assessed in all patients with pronated grip-view radiographs preoperatively and postoperatively. Preoperative ulnar variance ranged from +1 to +6 mm. Results: All patients were followed for at least 24 months. Union of the Osteotomy site was achieved at a mean of 8.2 weeks. The union rate was 98.8%. There were 2 cases of nonunion, which required additional surgery. The mean postoperative ulnar variance was +0.2 mm (range, −1 to +1.5 mm) after a mean overall ulnar shortening of 2.5 mm. All patients returned to their previous work, in a mean of 4 months. The plate was removed from 12 patients because of plate-related symptoms. No other complications were encountered. Conclusions: The Step-Cut ulnar shortening Osteotomy provides ample bone-to-bone contact and simplifies control of rotation. Stable internal fixation with standard techniques allowed an early return to functional activities. Palmar placement of the plate diminishes the need for plate removal. This is a simple and less expensive technique for ulnar shortening that does not require the use of special instrumentation in patients with ulnar impaction syndrome. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Step-Cut Distal Ulnar–Shortening Osteotomy
Journal of Hand Surgery (European Volume), 2005Co-Authors: Nickolaos A. Darlis, Italo C. Ferraz, Robert W. Kaufmann, Dean G. SotereanosAbstract:Purpose Several techniques for ulnar-shortening osteotomies have been described in recent years, reflecting the difficulties that sometimes are encountered in what seems to be a relatively simple procedure. We describe the use of a simple Step-Cut ulnar-shortening Osteotomy stabilized with a lag screw and a palmarly placed 3.5-mm neutralization plate. Methods Twenty-nine patients had the surgery. The indication was ulnar-impaction syndrome in 23 patients and symptomatic ulnar-plus variance secondary to trauma in 6 patients (4 with previous distal radius fractures, 2 with Essex-Lopresti injuries). The preoperative ulnar variance ranged from +1 mm to +6 mm. Results The mean follow-up period was 34 months. All osteotomies healed uneventfully. The mean postoperative ulnar variance was +0.2 mm (range, −1 mm to +1.5 mm). Three patients had hardware removal. Conclusions The Step-Cut Osteotomy resulted in solid union in all patients. It provides ample bone-to-bone contact and easier control of rotation, and no special instrumentation is necessary. Stable fixation permitted early mobilization of the wrist and palmar placement of the plate minimized the need for plate removal. This is a simple and effective technique for ulnar shortening.
