BACKGROUND: Tendon gliding is key to optimal recovery of hand function after complex tendon injuries. Gliding is facilitated by a low-friction gliding surface that is normally provided by the periosteum of the underlying bone. However, significant injuries may damage the periosteum, which must be reconstructed to allow uninterrupted tendon excursion. The absence of the periosteum may compromise a tendon's ability to glide freely, thereby limiting the range of motion. METHODS: Six digits in 4 patients with complex, composite soft tissue defects involving tendon, periosteum, and skin of the hand underwent surgical repair. Each digit had disruption of the bony cortex underlying the tendon injury including periosteal loss. Through an incision on the dorsum of the ipsilateral wrist, an extensor retinaculum graft corresponding to the size of the periosteal defect was harvested. It was then sutured into place over the bare cortex to replace the lost periosteum. RESULTS: All the 6 digits in the 4 patients had complete return to function. Additionally, all patients had near normal strength in the repaired hand along with excellent tendon excursion in both flexion and extension. The average time of follow-up of this series of patients was 1.5 years. CONCLUSIONS: Extensor retinaculum grafting to replace lost periosteum is a technique that is easily used, uses locally available autogenous tissues, and produces excellent tendon function. Additionally, the histologic similarities between extensor retinaculum and periosteum add scientific merit to this novel approach. On the basis of our experience, we recommend the use of extensor retinaculum for periosteal reconstruction to provide an adequate gliding surface for a reconstructed tendon.

We report a case of lipoblastoma of the hand in a 19-month-old female patient with a history of cleft palate. The incidence of lipoblastoma and cleft palate individually is extremely rare. To the best of our knowledge, only 1 other case of a patient with both cleft palate and lipoblastoma exists in the literature. Lipoblastoma is a rare benign neoplasm in adipose tissue almost exclusively found in children younger than 3 years. Cytogenetic testing has shown that lipoblastomas characteristically share a clonal chromosomal rearrangement affecting the long arm of chromosome 8. Furthermore, recent research has shown that the 8q chromosome is an important genetic risk factor for cleft palate development. We describe the second case linking cleft palate with this rare tumor and provide evidence for a potential genetic association.

We report a case of a traumatic proximal interphalangeal joint injury with loss of the middle phalangeal base and articular surface, which was reconstructed with an autologous hemi-toe osteochondral graft. The patient had a 72 degrees improvement in proximal interphalangeal joint motion and excellent functional improvements. Postoperative computed tomography imaging indicated bony union and articular congruence.

BACKGROUND: Fingertip injuries are the most common hand injuries presenting for acute care. Treatment algorithms have been described based on defect size, bone exposure, and injury geometry. The authors hypothesized that despite accepted algorithms, many fingertip injuries can be treated conservatively. METHODS: A prospectively collected retrospective review of all fingertip injuries presenting to Bellevue Hospital between January and May of 2011 was conducted. Patients were entered into an electronic database on presentation. Follow-up care was tracked through the electronic medical record. Patients lost to follow-up were questioned by means of telephone. Patients were analyzed based on age, mechanism of injury, handedness, occupation, wound geometry, defect size, bone exposure, emergency room procedures performed, need for surgical intervention, and outcome. RESULTS: One hundred fingertips were injured. Injuries occurred by crush (46 percent), laceration (30 percent), and avulsion (24 percent). Sixty-four percent of patients healed without surgery, 18 percent required operative intervention, and 18 percent were lost to follow-up. Patients requiring operative intervention were more likely to have a larger defect (3.28 cm versus 1.75 cm, p < 0.005), volar oblique injury (50 percent versus 8.8 percent, p < 0.005), exposed bone (81.3 percent versus 35.3 percent, p < 0.005), and an associated distal phalanx fracture (81.3 percent versus 47.1 percent, p < 0.05). Patients requiring surgical intervention had a longer average return to work time when compared with those not requiring surgical intervention (4.33 weeks versus 2.98 weeks, p < 0.001). CONCLUSION: Despite current accepted algorithms, many fingertip injuries can be treated nonoperatively to achieve optimal sensation, fine motor control, and earlier return to work.

BACKGROUND: : Dupuytren's disease is a common benign fibroproliferative disorder of the hand. Epidemiologic studies have reported significant variation in disease prevalence among races, focusing primarily on those of northern European descent. In contrast, Dupuytren's disease in the Hispanic population has received little attention. Thus, in this study, the authors aimed to determine the prevalence and operative rate of Dupuytren's disease in the Hispanic, black, white, Asian, Native American, and other races and to characterize the disease presentation in Hispanics who required surgical treatment. METHODS: : A retrospective review was conducted to identify the racial distribution of Dupuytren's disease patients seen at Bellevue Hospital between July of 2000 and August of 2010. In Hispanic patients requiring surgical treatment for their disease, data were collected on the following parameters: age, sex, ethnicity, hand dominance, hand affected, and digits operated on. Epidemiologic factors including smoking, alcoholism, diabetes mellitus, hypercholesterolemia, epilepsy, and hypertension were also evaluated. RESULTS: : Dupuytren's disease prevalence was found to be 533 per 100,000 in Hispanics. Of these patients, 1.8 percent required surgical treatment, and this group was characterized by the following comorbidities: smoking (57.1 percent), hypertension (57.1 percent), alcoholism (52.4 percent), diabetes mellitus (47.6 percent), and hypercholesterolemia (19.0 percent). CONCLUSIONS: : The authors' results indicate that Dupuytren's disease is more prevalent in the Hispanic population than previously reported. Although the epidemiologic factors identified in Hispanics with Dupuytren's disease are similar to those in other races investigated, there are important differences with respect to clinical presentation and surgical treatment

BACKGROUND: : Autologous bone grafts, often harvested from the iliac crest, are the criterion standard for secondary alveolar cleft repair. The best technique for harvest remains controversial. Minimally invasive techniques have been used for bone graft harvest in cleft patients, but outcome studies have been limited by small numbers of patients. METHODS: : A total of 104 patients undergoing bone grafting for alveolar cleft were reviewed. Fifty-five consecutive patients underwent minimally invasive iliac bone graft harvest using the Acumed power-driven trephine system performed by the same surgeon. These patients were compared with 49 control patients undergoing a similar procedure in which the traditional method of open iliac bone harvest with an osteotome was used. RESULTS: : Operative time for the bone graft harvest was significantly shorter with the Acumed device when compared with the osteotome (2.37 hours versus 3.26 hours, p < 0.001). Patients who underwent minimally invasive Acumed bone harvest required significantly less postoperative analgesia than did patients who underwent osteotome harvest, for both narcotic (0.31 mg/kg versus 1.64 mg/kg, p < 0.001) and nonnarcotic (15.1 mg/kg versus 27.2 mg/kg, p < 0.01) pain medication. Acumed patients had significantly less pain on discharge (0.26 versus 3.1 pain scores on a scale from 0 to 10, p < 0.001) and left the hospital more quickly (23.3 hours versus 30.1 hours, p < 0.001). CONCLUSION: : Minimally invasive bone graft harvest technique using the trephine system offers a superior alternative to the conventional open iliac bone harvest method for patients undergoing secondary alveolar cleft repair, with shorter operative time, decreased requirement for pain medications, less pain on discharge, and a shorter hospital stay.

BACKGROUND: : Bellevue Hospital Medical Center is a level 1 trauma center in New York and a major referral center for complex hand injuries and amputations. These injuries typically occur at the workplace and are thought to be highly litiginous in nature. This study was conducted to analyze the cases involving hand surgery litigation related to trauma over the last 8 years at this institution. METHODS: : The authors performed a retrospective chart review of all claims filed against Bellevue Hospital Medical Center after treatment for a hand injury during 2001 to 2009. Twenty-three patients in total were identified and reviewed for age, mechanism/type of injury, complications, decision to replant, average time after injury to post claim, and whether settlement was obtained. RESULTS: : One of 23 patients who filed suit against Bellevue Hospital Medical Center received a successful settlement involving an incident surrounding the loss of a nonreplantable part. Of 168 patients in whom 219 replantations/revascularizations were performed, five patients filed claims, all surrounding a failed attempt. In total, there were seven complications: five failed replants, one failed thenar flap, and one patient who needed a revision completion amputation. CONCLUSIONS: : The majority of the patients who filed claims did so because of the decision not to replant. Only 2.98 percent (five of 168) of all attempted revascularization/replantation patients filed claims against the authors' institution; all claims were notably dropped. The legal system appears to support physicians and institutions that treat these complex injuries. Better patient understanding of the decision-making process and complications involving treatment of traumatic hand injuries may decrease the number of future lawsuits

BACKGROUND: A bulky appearance is one of the major patient complaints after extremity reconstruction after fasciocutaneous flaps. Serial debulking procedures with staged excision are required to improve aesthetic and functional outcome, but these methods risk injury to the vascular pedicle and often require multiple procedures for adequate thinning of the flap. We suggest the use of power-assisted suction lipectomy for the debulking of fasciocutaneous flaps in the upper and lower extremities as a safe, effective, and efficient procedure. METHODS: From 2006 to 2009, we performed power-assisted suction lipectomy on the upper and lower extremities of 16 flaps in 15 patients who had previously undergone reconstruction with fasciocutaneous flaps after a traumatic injury. RESULTS: There was 100% flap survival without any complications. Only 2 of the 16 (12.5%) flaps required a secondary revision for further contouring. CONCLUSIONS: In our experience power-assisted suction lipectomy is a safe and excellent adjunct in fasciocutaneous flap debulking and reduces the number of secondary revision procedures necessary. We recommend its use as an adjunct in debulking and contouring flaps used in extremity reconstruction

Hemangiopericytoma (HPC) is a rare vascular tumor arising from contractile cells around blood vessels, with the potential for malignant degeneration. Up to 10% of HPC occurs in children. Standard therapy for this tumor is surgical excision. We report the case of a 6-month-old infant with giant HPC involving the hand. Chemotherapy resulted in a decrease in tumor size, allowing for salvage of most of the hand and fingers. Preoperative chemotherapy should be considered in the care of HPC tumors involving the upper extremity in children
