The treatment of choice in nondisplaced hook of hamate fractures is conservative, with lower arm splinting. Displaced fractures should be treated operatively, whereby excision of the fragment or open reduction and internal fixation are described. A hamulus ossis hamati fracture was verified in 14 patients (mean age, 42 years; range, 21 to 73 years) including 11 men and three women. In six patients (42.9 percent), conservative treatment was initiated immediately after trauma with a lower arm cast for 6 weeks, and eight patients (57.1 percent) were operated on primarily. In five patients (35.7 percent), the fragment was excised, and in three patients (21.4 percent), an open reduction and internal fixation was performed using a screw. In five of six patients treated conservatively, nonunion of the fracture with persisting clinical symptoms developed. All of those patients were treated operatively, whereby three patients underwent excision and two patients underwent screw fixation, which led to elimination of the symptoms. One patient was asymptomatic despite nonunion of the fracture and rejected surgery. All of the eight patients operated on primarily were asymptomatic 3 months after surgery. Therefore, the success rate of primary surgical treatment (eight of eight) was significantly higher compared with conservative treatment(one of six). Finally, all 14 patients were asymptomatic at late postoperative follow-up. The clinical outcome of patients with hook of hamate fractures treated conservatively was disappointing. Therefore, primary surgical treatment is recommended. In our patients, excision and open reduction and internal fixation led to comparable results.

In situations of bony nonunions with poor skin coverage, transplantation of vascularized soft tissue in addition to bone graft is desirable. The use of the corticoperiosteal vascularized bone graft from the medial femoral condyle is well described. There are only anecdotal reports about its use as an osteocutaneous flap. This article presents our results with the use of an osteocutaneous flap from the medial femoral condyle. Between 2004 and 2009, four patients were treated with supracondylar osteocutaneous flaps for bony nonunions (tibia, ankle, calcaneous) with concomitant soft tissue defects. The size of the osseous grafts ranged from 3 x 5 to 6 x 5 cm. The supplying cutaneous vessels were an unnamed perforator of the descending genicular artery (two cases) or the saphenous branch (two cases). The first three cases healed primarily. Bony union was achieved between 32 and 170 days. The follow-up of the fourth case was too short to achieve a bony union. There was no flap loss or surgery-related complications at the donor site. The transfer of free combined vascularized corticoperiosteal-cutaneous flaps seems to be ideally suited for postradiation-induced fractures or chronic nonunions with poor chances of spontaneous healing and a concomitant small skin defect.

Symptomatic nonunion frequently results after conservative treatment of hamate hook fractures, emphasizing the need of appropriate surgical strategies. A retrospective analysis of 8 patients with nonunions treated by fragment excision or open reduction and internal fixation (ORIF) at 3 centers was performed. The literature was reviewed for treatment options, as bone grafting and low-intensity pulsed ultrasound. Although fragment excision is advocated as the "gold standard" in nonunion, reports on functional results are controversial, and recent anatomic and biomechanical studies of the hook challenge this opinion. In our patients, complete relief of symptoms and comparable functional results were observed after ORIF or fragment excision. Bone grafting could supplement ORIF in selected cases. Low-intensity pulsed ultrasound may evolve as a conservative treatment option. Several alternatives to hook excision are available aiming at complete anatomic and functional recovery of hamate hook nonunion. Further experience is needed before general recommendations can be formulated.

Multistructural reconstructive procedures are often required to achieve a sufficient reconstruction of the forearm and/or hand after radical tumor resection. Clear margin (R0) resection is the main therapeutic goal for the treatment of sarcomas. Plastic reconstructive procedures with the possibility of microvascular transplantations play a key role in coverage of complex defects. In our department, 20 patients with soft tissue sarcomas of the hand/forearm were treated between 1995 and 2005. Eleven patients were male, nine female. The average follow-up time was 42 months. The most common tumor type was the myxoid fibrous histiocytoma in 10 cases. Six patients received a free microvascular transplantation to cover the defect after radical resection, local flaps, or primary closure was performed in five cases. Preservation was not possible in nine cases. Ten patients received radiation and four obtained chemotherapy postoperatively (two patients received neoadjuvant chemotherapy). Extremity function, the DASH questionnaire, and patient satisfaction were our examination parameters. Our results show the necessity of plastic-surgical reconstruction of the forearm and hand as an integrative component of modern sarcoma therapy. It can be concluded that plastic-surgical reconstruction of the extremity plays a key role within the multimodal concept of therapy for patients with sarcoma at the forearm and hand.Soft tissue sarcoma is a rare entity with an incidence of only 1% of all malignant tumors. Fortunately most tumors of the hand and forearm are benign; however, 2.2% of the tumors of the hand are malignant. 1-6 More than 70% of the malignant neoplasms of the hand and forearm involve the skin. Forty-two percent of all sarcoma are located in the extremities and only one-third of them affect the upper limb. 1,2,[7][8][9][10] Radical tumor resection with clear margins is the main therapeutic goal for the treatment of sarcoma of the forearm and hand. Compared with survival rates and limb function, limb salvage surgery combined with adjuvant treatment is the favored therapy. The 5-year survival rate of radical resection and reconstruction averages more than 60%. In comparison to the survival rate after limb amputation there are no significant

Background:The purpose of this study was to investigate the influence of plate location during ulna shortening osteotomy on the incidence of hardware irritation and clinical outcome.Methods:Forty patients (17 women, 23 men; mean age, 47 years) who underwent a shortening osteotomy of the ulna due to idiopathic ulna impaction syndrome were examined after a mean of 36 months. All complications and secondary procedures were extracted from the patients’ records.Results:The rate of hardware removal was higher in patients who had a dorsal placement of the plate in comparison with ulnar or palmar placements, although this difference was not statistically significant. Apart from hardware irritation, there were 4 nonunions, 1 secondary osteoarthritis of the distal radioulnar joint, and 1 case of chronic irritation of the dorsal branch of the ulnar nerve, which required secondary surgery. The incidence of secondary surgery other than hardware removal was not significantly related to the original location of the plate.Conclusions:Secondary surgery after ulnar shortening osteotomy is common. However, we found no difference in clinical outcomes based on plate location.

This study assessed the clinical and radiological outcomes after treatment of scaphoid non-union of the proximal third by non-vascularised bone grafts and stabilisation by Mini-Herbert Screws from a dorsal approach. Thirty-one patients, one woman and 30 men, were reviewed retrospectively at a mean of 42 (12-77) months. All patients received pre- and postoperative CT scans to assess bone union. In addition to demographic data, the range of motion, grip strength, DASH score, Krimmer score, Mayo wrist score and radiological parameters (carpal height, scapholunate and radiolunate angles) were recorded. Bone union was achieved in 21 patients. The average DASH score in patients with bone union was 12 and that in patients with persistent non-union it was 30. No progression into carpal collapse or increase of scapholunate angles was detected. Our study demonstrates that acceptable union rates can be achieved with non-vascularised bone grafts, and this technique compares favourably with other reports in the literature.

Fractures of the scaphoid are relatively common injuries. Differentiation between stable and unstable fractures (Herbert classification) cannot always be made with conventional radiographs and should be additionally evaluated by computed tomographic scan. Under most circumstances, minimal invasive surgery with cannulated screws is currently the treatment of choice. Cast immobilization is not necessary. This article describes the technique of fracture fixation in the middle third of the scaphoid from a palmar approach and early functional outcomes. The outcome assessment included measurement of active range of motion as well as grip strength and the Disability of the Arm, Shoulder and Hand questionnaire as a measurement of activities of daily living. Fifty-four patients with acute scaphoid fractures were treated with minimal invasive screw fixation between April 2001 and January 2005. All patients in this retrospective study received a preoperative computed tomographic scan before surgery. Bony consolidation was found in 52 cases after 6 weeks; 2 patients required reosteosyntheses. The results demonstrate that minimal invasive screw fixation leads to satisfying functional outcomes within a few weeks.
