Article: Linked total elbow arthroplasty as treatment of distal humerus fractures.
[show abstract] [hide abstract]
ABSTRACT: Treatment of distal humerus fractures may be challenging, especially in the elderly patient. Total elbow replacement has been proposed as an option in selected patients. We present the results of a linked elbow replacement in 16 patients with a comminuted fracture of the distal humerus which was not considered amenable to reliable open reduction and internal fixation. At a mean follow-up of 57 months, average range of motion was from 28 degrees to 117 degrees of flexion-extension. Five patients with moderate to severe pain (31%) were not satisfied with the results of the operation. Three patients had an infection which resulted in implant removal in one patient. Eight patients had symptoms of sensory ulnar nerve neuropathy. Our results show that elbow replacement may be an optimal solution for highly comminuted osteoporotic fractures, if there are no associated complications. However, the rate of significant and minor complications such as infection or postoperative ulnar nerve symptoms is probably higher than reported. Appropriate selection of ideal candidates for this procedure and meticulous surgical technique are of paramount importance in reducing the risk of complications.Acta orthopaedica Belgica 08/2012; 78(4):465-72. · 0.40 Impact Factor -
Article: Universal total wrist arthroplasty: midterm follow-up study.
[show abstract] [hide abstract]
ABSTRACT: We reviewed 21 consecutive patients who underwent a total wrist arthroplasty as a primary procedure between October 2001 and February 2007. The purposes of the present study were to communicate our midterm results and to compare them with previously published series. We evaluated all patients clinically and radiologically. We used the Patient-Related Wrist Evaluation a primary outcome measure. The mean follow-up was 5.5 years (range, 3-8 years). A total of 14 patients had rheumatoid arthritis, including 1 with juvenile arthritis, and 1 each had psoriatic arthritis, systemic lupus erythematosus, and undifferentiated spondyloarthropathy. Of the remaining 4 patients, 2 had grade IV Kienböck disease, 1 had degenerative arthrosis, and 1 had chondrocalcinosis. Postoperative Patient-Related Wrist Evaluation scores averaged 24 points (SD, 21 pints) out of 100 (worst score). When the patients were specifically asked about pain and function of the arthroplasty, 20 claimed to be satisfied or very satisfied with the procedure. Two early and 3 late complications occurred. One patient had a wound hematoma and another had a superficial wound infection, both of which resolved with no further complications during the immediate postoperative period. In 2 patients, there was some osteolysis around the screw inserted into the medullary canal of the index metacarpal, but not in the trapezoid bone. One patient had a slight loosening of the distal component with subsidence on the ulnar side of the carpus. There have been no dislocations or surgical revisions of the components. Based on our study, a total wrist arthroplasty should be considered as a good alternative to arthrodesis for patients who wish to preserve some degree of mobility of the wrist.

Article: Linked total elbow arthroplasty as treatment of distal humerus nonunions in patients older than 70 years.
[show abstract] [hide abstract]
ABSTRACT: Treatment of distal humerus nonunions may be challenging, especially in the elderly patient. Total elbow replacement has been proposed as an option in selected patients, but a high index of complications has been reported. We present the results of a linked elbow replacement in six patients older than 70 years with a symptomatic nonunion of the distal humerus. At a mean follow-up of 40 months, average range of motion was from 15 degrees to 125 degrees of flexion-extension. Only one patient had moderate pain in the elbow, but all six were satisfied with the results of the operation. The arthroplasty allowed all patients to do basic tasks of daily living activities. Our results are encouraging, and show that linked elbow replacement is a good option in elderly patients with symptomatic nonunions of the distal humerus. Appropriate selection of ideal candidates for this procedure is a key factor in reducing the risk of complications.Acta orthopaedica Belgica 06/2011; 77(3):304-10. · 0.40 Impact Factor -
Article: Nerve-sparing dorsal and volar approaches to the radiocarpal joint.
[show abstract] [hide abstract]
ABSTRACT: Surgical approaches to the wrist joint have traditionally been focused on providing wide exposure to allow adequate access to the carpus. In light of recent investigations on the innervation and proprioception of the wrist joint, one should also take into consideration not to denervate the wrist capsule and ligaments. In this manuscript, we propose 2 surgical approaches to the dorsal and volar radiocarpal joint, intended to minimize damage to the innervation of the capsule while providing ample access to the wrist.The Journal of hand surgery 07/2010; 35(7):1070-4. · 1.33 Impact Factor -
Article: Multislice computed tomography angiography of the fourth dorsal interosseous space in cadavers.
[show abstract] [hide abstract]
ABSTRACT: To study computed tomography angiography (CTA) findings and compare anatomic correlation of the 4th dorsal metacarpal spaces and to determine the role of this technique for anatomic studies and flap design. Hands from 17 cadavers were injected with a radiopaque mixture. The specimens were imaged using 16-detector-row computed tomography. Each image was analyzed by a radiologist, a plastic surgeon, and an anatomist. The following data were recorded: the presence of the 4th dorsal metacarpal artery, proximal and distal communicating branches and distal recurrent branch, and the number of cutaneous perforators. Afterwards, a meticulous dissection was carried out. A correlation between the radiologic findings and the gross anatomy was established. In all specimens, the 4th dorsal metacarpal artery and distal recurrent branch were identified. In 15 cases, at least 1 perforator was identified within the 4th space. In 2 cases, no perforator was identified. In all cases, the radiologic findings correlated with the anatomic findings in the dissection. Multislice CTA provides good-quality information about the vascular anatomy of the dorsal aspect of the hand, including perforator vessels less than 0.5 mm in diameter. Multislice CTA allows for observation of the axis, trajectory, and branching pattern of the blood vessels and, most importantly, demonstrates the anatomic relationships among blood vessels, bones, and soft tissue.The Journal of hand surgery 01/2009; 33(10):1860-7. · 1.33 Impact Factor -
Article: Transverse loaded pronosupination test.
[show abstract] [hide abstract]
ABSTRACT: A new test to evaluate the ability of the distal radioulnar joint to sustain transverse loads while the forearm rotates from pronation to supination is described. Both arms were tested in 100 normal volunteers. The average weight-bearing capability of the normal unsupported forearm was 5.07 kg, equating to a force of 49.8 N. The test may be useful in the assessment of pathological conditions involving weakness of the forearm rotator muscles, with or without joint incongruity, as well as being an indirect way to assess the load-bearing capacity of radioulnar implants.Journal of Hand Surgery (European Volume) 09/2008; 33(6):765-7. · 1.17 Impact Factor -
Article: Cutaneous perforators of the fourth dorsal interosseous space: anatomic study.
[show abstract] [hide abstract]
ABSTRACT: Many investigators have studied the vascular anatomy of the dorsal metacarpal arteries but little attention has been paid to the exact distribution of the cutaneous perforators of the dorsum of the hand. We present an anatomic study of the cutaneous perforators within the fourth dorsal interosseous space, which was supposed to have the most inconsistent vascular anatomy. Twenty hands were dissected after black latex injection. A skin paddle was outlined along the fourth dorsal metacarpal space. Suprafascial dissection was performed, preserving any vessel piercing the fascia and reaching the skin. Each perforator was traced back to its origin. The location and origin of each perforator was recorded by digital pictures and measured from a reference point. In 17 of the cases (85%) at least 1 perforator was identified within the fourth space piercing the dorsal interosseous muscle fascia and reaching the skin. In 10 hands, a perforator branching off the proximal communicating branch was identified, located a mean distance of 11 mm from the carpometacarpal joint line. A dissectable perforator was found consistently (17 of 20; 85%) in the proximal third of the fourth dorsal interosseous space branching off the proximal communicating branch. Few perforators branch off the middle third of the dorsal metacarpal artery. The perforator described herein shows the connection between the superficial and deep vascular systems of the ring and small metacarpal spaces, and establishes the anatomic basis for reconstructive flaps.The Journal Of Hand Surgery 03/2007; 32(2):246-51. · 1.35 Impact Factor -
Article: Treatment of radiocarpal degenerative osteoarthritis by radioscapholunate arthrodesis and distal scaphoidectomy.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to assess wrist pain, range of motion, and the presence of radiographic midcarpal degenerative joint disease (DJD) in patients who had a distal scaphoidectomy in association to a radioscapholunate (RSL) arthrodesis and to compare these findings with prior studies of patients with only an RSL fusion. Sixteen patients with radiocarpal DJD treated by RSL arthrodesis and distal scaphoidectomy were evaluated retrospectively for pain relief and range of motion at an average follow-up period of 37 months (range, 12-84 mo). Radiographs were assessed for the presence of secondary radiographic midcarpal DJD. Complete pain relief was obtained in 10 patients, 3 patients complained of slight pain during strenuous loading, and 3 patients had occasional pain with regular activities. The average postoperative ranges of motion were 32 degrees of flexion, 35 degrees of extension, 14 degrees of radial deviation, and 19 degrees of ulnar deviation. Two patients exhibited secondary midcarpal DJD. These results are significantly better compared with those previously published about RSL arthrodesis alone in terms of residual pain and decrease of wrist radial deviation and flexion. Patients who require an RSL arthrodesis for the treatment of severe localized radiocarpal DJD appear to have less pain and to retain more flexion and radial deviation if the distal scaphoid is excised concomitantly. This associated procedure also may help prevent secondary midcarpal DJD.The Journal Of Hand Surgery 02/2005; 30(1):8-15. · 1.35 Impact Factor -

Article: The anatomic basis of the fourth dorsal metacarpal flap: a cadaveric dissection.
[show abstract] [hide abstract]
ABSTRACT: To study the vascularization of the fourth dorsal intermetacarpal space and to determine the contribution of the dorsal metacarpal artery and the interosseous muscle fascia to flap viability. The fourth dorsal intermetacarpal space is considered to be less reliable as a donor site because of previously reported vascular variations. We performed 15 cadaver dissections. The vascular tree was injected with black latex through the radial and ulnar arteries at the forearm. The skin paddle was designed within the fourth intermetacarpal space. The proximal border was placed at the wrist joint line. The distal border was located 1 cm proximal to the head of the fourth and fifth metacarpal. The width of the skin paddle was based on whether the donor site could be closed directly. A zigzag incision was performed from the distal end of the skin paddle to the volar edge of the interdigital web. The borders of the skin paddle were outlined down to the fascia of the dorsal interosseous muscle. Once the fourth dorsal metacarpal artery was identified each vascular connection was dissected and recorded. The fourth dorsal metacarpal artery was identified in all specimens under the dorsal interosseous muscle fascia. The distal recurrent branch consistently entered the base of the flap superficial to the extensor digitorum communis tendon of the small finger and the dorsal interosseous muscle fascia. Cutaneous perforators branching off the dorsal metacarpal artery were not found consistently. Reliable flaps can be raised from the fourth dorsal intermetacarpal space based solely on the distal recurrent branch, excluding the dorsal metacarpal artery and interosseous muscle fascia.The Journal Of Hand Surgery 31(5):711-6. · 1.35 Impact Factor
