ABSTRACT
Management of elbow arthritis in younger and higher demand patients is challenging and may benefit from a distal humerus hemiarthroplasty that employs a noncemented method of implant fixation and stabilizes the elbow through ligament reconstruction. By not replacing both articulating surfaces, hardware longevity may be improved. We describe a novel system that may be indicated for the treatment of posttraumatic or primary osteoarthritis of the distal humerus. The step-by-step technique for surgical implantation of this uncemented distal humerus hemiarthroplasty is described and illustrated.
ABSTRACT
BACKGROUND: Although fingertip and nail bed injuries have a high incidence, appropriate management of nail bed injuries remains controversial. This study is the completion of data derived from nail bed injuries with follow-up of a minimum of 6 months to suggest an appropriate treatment. METHODS: In the retrospective study, we analyzed data from 549 nail bed injuries for 6 years and age, type of injury, fractures, treatment methods, and outcomes were reviewed. Results were determined and these were divided to identical to the opposite group, abnormalities based on Zook criteria. Statistical analysis was done according to injury category (type, site, nail substitute, and fracture) and overall final grade. RESULTS: Over 50% (293 cases) had excellent results. Rates of very good, good, fair, and poor results were 22.6%, 11.3%, 6.2%, and 6.6%, respectively. Poorer results were obtained for fold injuries, crush, and avulsive injuries. The presence of a fracture was associated with poor results. CONCLUSIONS: The cause of poor results is thought to be multifactorial. Although, overall outcomes were good, nail splitting, nail roughness, and nail adherence can cause dirtiness, catching, bending, and various cosmetic problems. Thus, careful suture and replacement of nail to nail fold are important to reach good results.

INTRODUCTION: Although xanthogranuloma is known to be related to trauma or mucosa, possibly developing around a periorbital or oral lesion, xanthogranuloma related to sinusitis urgery has not been reported. We present a case of xanthogranuloma formation after endoscopic sinus surgery (ESS). PRESENTAION OF CASE: A 54-year-old man with pain and swelling in the right periorbital area presented to our clinic. He had had a blowout fracture treated by ESS 2 years prior. Physical examination and computed tomography revealed an â¼1-cm × 0.7-cm cystic mass on the right lower eyelid. Subciliary exploration found a fat-like mass that we completely excised. A histological examination revealed xanthogranuloma. No recurrence was observed for 1 year. DISCUSSION: If the wall between the sinuses and the orbit and the mucosa of the maxillary sinus are injured during ESS, infectious material and hematoma could develop into chronic granulomatous inflammation. In addition, a large antrostomy and/or a damaged nasolacrimal duct are risk factors for xanthogranuloma. Antibiotics can treat the disease and prevent infection. Progressive growth of the lesion and its infiltration into surrounding tissues may result in surgical resection. CONCLUSION: Because many masses are idiopathic, the development of xanthogranuloma after simple ESS or a nondisplaced blowout fracture is possible. Although xanthogranuloma progression usually is benign and without specific complications, it may be sight- or life-threatening. Antibiotics and surgical resection are the treatments of choice and the latter can be a diagnostic tool. Physicians should be aware of the possibility of granuloma formation in patients who have undergone ESS.
ABSTRACT
Background: Self-inflicted wrist lacerations have the potential to lead to crippling sequelae and repeated suicidal attempt. To obtain good results, we have treated self-inflicted wrist lacerations using a multidisciplinary team - emergency, hand surgery, psychiatry, and rehabilitation. This study aims to review features of this type of injuries and suggest multidisciplinary team approach as an optimal treatment. Methods: Our multidisciplinary approach can be summarized as follows: initial evaluation, psychological interview, surgery, and rehabilitation. The medical records including wound features, injured structures and psychological data were reviewed retrospectively. Assessment of functional outcomes, and comparative analysis of various psychological parameters were conducted. Results: Most patients resulted in excellent or good functional outcomes. Five patients reattempted wrist cutting with suicidal intent during follow-up. Only 21.3% patients had a suicidal intent and it was not associated with injury severity and functional recovery. Alcohol ingestion and presence of associated injuries was significant different between severity groups. Presence of suicidal intent was irrelevant to injury severity and functional recovery, but relevant to alcohol ingestion, presence of associated injuries and presence of psychiatric diagnosis. Conclusions: In order to minimize catastrophic disability and repeated suicide attempts, a balanced multidisciplinary approach is one of the best methods to obtain excellent functional outcomes and prevent repeated injuries in patients with self-inflicted wrist lacerations.

INTRODUCTION: Iatrogenic fractures after failed K-wire fixation in the management of a carpometacarpal (CMC) joint fracture-dislocation have not yet been reported (Hsu et al., 2011). We present a case of K-wire-related complication in the management of a CMC joint fracture-dislocation and highlight the importance of planning K-wire placement and minimizing the number of K-wire passes. PRESENTATION OF CASE: After beating his hand against a wall, a 22-year-old patient visited our clinic complaining of a swollen and painful wrist. Following our protocol, reduction and K-wire fixation was planned. During these procedures, the resident of our team made several attempts to insert transfixation pins and radiologic finding demonstrated incorrect placement of the K-wire track. The patient visited the outpatient clinic at 5 weeks postoperatively then we removed the K-wires and began mobilization. Two weeks later, the patient came back with acute onset of pain and swelling at the 5th metacarpal area. DISCUSSION: Stahl and Schwartz reported that 27.8 % of complications related K-wire were due to technical failure and 90 % of technical failure were caused by hospital residents. Well-established guidelines and supervision by a highly experienced surgeon is likely to reduce the rate of technical failure. Multiple passes of the K-wire have resulted in blunting of the K-wire and subsequent heat generation then lead to subsequent loosening and loss of fixation. CONCLUSION: Preoperative planning, marking the K-wire route, and appropriate K-wire thickness minimize such complications. Patients should be informed that following K-wire removal, the residual holes could be subject to stress risers.
ABSTRACT
BACKGROUND: Enophthalmos may not appear immediately after trauma due to periorbital swelling in a blowout fracture, and preoperative measurements of enophthalmos cannot be used as a reliable guideline. It is important to predict the eventual final extent of enophthalmos in order to determine whether to perform surgery, and there have been several attempts to predict the degree of late enophthalmos using preoperative orbital volume. The purpose of this study is to investigate the correlation between the orbital volume ratio (OVR) with final enophthalmos and the palpebral fissure, and to find the OVR that induced 2 mm of enophthalmos in unilateral unoperated blowout fractures. METHODS: We retrospectively reviewed the medical records of 38 patients and divided them into 3 groups, determined by the fracture location. The relationships between the OVR and both the degree of enophthalmos and the palpebral fissure ratio (PFR) were assessed and, in particular, the OVR that induced 2 mm of enophthalmos was sought. RESULTS: Enophthalmos increased in proportion to the OVR, and there was a highly significant correlation between the increase in the OVR and the degree of enophthalmos (P<0.05). On the other hand, there was no correlation between OVR and PFR (P>0.05). The OVR that induced 2-mm enophthalmos was 112.18%. CONCLUSIONS: The final degree of enophthalmos can be estimated by the preoperative measurement of OVR. Preoperative measurements of OVR can be used as quantitative values to predict the final degree of enophthalmos in pure blowout fractures.
ABSTRACT
The consequences of facial trauma remain of great significance both functionally and esthetically. Traffic accident-related facial trauma is a frequent and significant cause of maxillofacial injury. The purpose of this study was to determine the natural history of traffic accident-related facial injuries in 846 patients over a 10-year period at a regional emergency center. The authors report a retrospective study of 846 patients with facial trauma from traffic accidents. The medical records of these patients were reviewed and analyzed to determine clinical characteristics, treatments, and outcomes of traffic accident-related facial trauma. In total, 687 of the 846 patients (81.2%) had fractures of the face, and nasal bone fractures were the most common followed by zygomatic complex fractures, blow-out fractures, and maxilla fractures. About 51.2% patients had open wounds on the face, such as lacerations, abrasions, skin or soft tissue defects, and friction burns. Only 7.4% of patients were treated conservatively and the others underwent repair or closed and open reduction. The complication rate was 46.3%, and scars were the most common followed by nose-related complication, hypoesthesia, and eyelid deformities. In addition, 47.6% of complication patients underwent secondary operations. Almost 15% of drivers were drunk, and about 8.7% were confessed drowsy during drive. Almost 30% of pedestrians were hit when they jaywalked across the street. Epidemiological data regarding traffic accident-related facial trauma are important and useful not only for decisions about patient care and developing optimal treatment regimens but to develop new methods to prevent injuries.

BACKGROUND: Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. METHODS: A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. RESULTS: Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. CONCLUSIONS: Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations.
ABSTRACT
Accurate perioperative evaluation of enophthalmos is important to determine the adequacy of surgical repair in orbitozygomatic fracture. In this study, the authors evaluated the degree of enophthalmos using Hertel and Naugle exophthalmometry in patients with pure blowout fracture and orbitozygomatic fracture, and compared the results. Fifty patients were divided into 2 groups: pure blowout fracture (Group A: control group, 25 patients) and orbitozygomatic fracture with displaced lateral orbital rim (Group B: experimental group, 25 patients). Hertel and Naugle scales were measured before and 6 months after surgery. The degree of lateral orbital rim advancement was assessed by comparing the difference between the perioperative change of the Hertel and Naugle scales. In Group A, the difference between the pre- and postoperative scales in the 2 exophthalmometry was statistically significant (P < 0.05). In Group B, the Hertel scale increased from -0.20 to -0.16 mm, with an insignificant difference between pre- and postoperative values (P > 0.05) and the Naugle scale increased from -0.88 to -0.20 mm, with a significant difference (P < 0.05). The Δ Hertel scale differed from the Δ Naugle scale by a mean of -0.64 mm, which represents the degree of lateral orbital rim advancement. Naugle exophthalmometry is a more reliable method for evaluation of enophthalmos in lateral orbital rim displaced orbitozygomatic fractures than Hertel exophthalmometry. The degree of lateral orbital rim advancement can be assessed by combined use of the Hertel and Naugle exophthalmometry in orbitozygomatic fractures.

Repairing a large inferomedial blowout fracture remains a challenge to orbital surgeon. The authors restored the fracture using combined transnasal and transorbital approaches using support of both paranasal sinuses. The authors compared surgical results of this novel method with those of the traditional procedure. Of 106 inferomedial blowout fracture patients who underwent surgical treatment between March 2007 and July 2013, 50 patients were selected in our study: 25 patients underwent the traditional procedure as controls, and the other 25 patients underwent orbital wall restoring surgery by our combined approach. Outcomes were evaluated in terms of the orbital volume ratio (OVR) and changes in Hertel scale. The OVR in the experimental group (7.19%) decreased more significantly than in the control group (2.71%) (Pâ<â0.05). In conclusion, the orbit was restored more successfully following orbital wall restoring surgery with dual support than by using the traditional inferomedial blowout fracture procedure.

BACKGROUND: Restoring the volume of orbital fracture is a challenge to the surgeons. We combined the transnasal balloon technique and the transorbital approach during orbital floor reconstruction, and compared the outcomes of this technique with those of the conventional transorbital approach. METHODS: Patients with unilateral pure orbital floor fracture were divided according to the surgical method: the direct transconjunctival approach (group A, 20 patients, control group) or the combination approach with the transnasal balloon technique (group B, 20 patients, experimental group). The orbital volume ratio (OVR) was measured with the use of computed tomographic scans, and enophthalmos was checked with a Hertel exophthalmometer. RESULTS: The orbital volume ratios in both groups decreased after surgery: it was more effectively decreased in group B (7.88%) than that in group A (1.69%) (P < 0.05). CONCLUSIONS: A combination of transconjunctival exploration and transnasal restoration with balloon support was more effective in restoring the orbital volume than the conventional method.

BACKGROUND: Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. METHODS: A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. RESULTS: In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). CONCLUSIONS: Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.
ABSTRACT
Most women with asymmetric pectus excavatum suffer from hypoplastic breasts. Hence, aesthetic correction of pectus excavatum has to address thoracic wall deformity, breast hypoplasia, and asymmetry.In retrospective series, 21 patients with a diagnosis of pectus excavatum with hypoplastic breasts were corrected using the pectus bar procedure and subpectoral augmentation mammoplasty. Results were assessed by analyzing prospectively collected data and calculating pectus indices from computed tomographic scans. At 12 months postoperatively, cosmetic evaluations were performed by the patients and by an independent, board-certified plastic surgeon using score from 0 (very poor) to 4 (very good).Cosmetic results evaluated by plastic surgeon were good (3.33 ± 0.03) and patient satisfaction was high (3.52 ± 0.03). Furthermore, indices of pectus excavatum were corrected to near normal.The authors consider that the pectus bar procedure with subpectoral augmentation mammoplasty is useful for the aesthetic correction of pectus excavatum with hypoplastic breasts.

The use of unipedicled venous flaps has been limited due to their unconventional perfusion patterns and inconsistent survival. Further information regarding the optimal conditions required for unipedicled venous flap coverage is needed to increase flap survival. The purpose of this study was to investigate the effect of the pedicle orientation and length on the viability of unipedicled venous flaps based on a review of our clinical experience. Thirty-one skin and soft tissue hand defects of 29 patients were treated with unipedicled venous flaps. Sixteen defects were treated with proximally pedicled flaps and 15 were treated with distally pedicled flaps. Five of the 16 proximally pedicled flaps and eight of the 15 distally pedicled flaps had pedicle lengths ≥ 5 cm. All proximally pedicled flaps survived, and distally pedicled flaps with pedicle lengths <5 cm (n = 7) also survived. Distally pedicled flaps with pedicle lengths ≥5 cm (n = 8) developed congestion within 1-2 days after surgery, and external bleeding was applied. Four of the eight flaps survived completely, and partial necrosis developed in the other four. The results demonstrate that proximally pedicled venous flaps of the hand can survive regardless of pedicle length. Distally pedicled venous flaps can also survive completely when pedicle length is <5 cm. Distally pedicled venous flaps with pedicle lengths ≥5 cm should be used with caution.

The purposes of this study were to observe bony orbital volume (OV) changes in pure blow-out fractures according to fracture location using a facial computed tomographic scan and to investigate whether the OV measurements can be used as a quantitative value for the evaluation of the surgical results of the acute blow-out fracture.Forty-five patients with unilateral pure blow-out fracture were divided into 3 groups: inferior (group I), inferior medial (group IM), and medial (group M) orbital wall fracture. The OV and the orbital volume ratio (OVR) were prospectively measured before and 6 months after surgery with the use of 3-dimensional computed tomographic scans, and the Hertel scale was measured with a Hertel exothalmometer.The preoperative OVR increased to the greatest extent in group IM, and the mean preoperative OVR was 121.46. The mean preoperative OVR in group I was significantly higher than that of group M (P = 0.005). The OV and OVR revealed a statistically significant decrease after the surgery (P = 0.000). The Hertel scale improved from -1.04 mm before the surgery to -0.78 mm after the surgery, but no significant difference was observed (P = 0.051).The OVR was useful as a quantitative value to evaluate pure blow-out fractures, compared with that of the Hertel scale. Fracture location-associated OVR studies are needed to make volume guidelines of blow-out fracture surgery.

BACKGROUND: Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve palsy patients. METHODS: Between August 2009 and November 2011, 6 unilateral incomplete facial nerve palsy patients underwent surgery for orthodromic temporalis muscle transfer. A preauricular incision was performed to expose the mandibular coronoid process. Using a saw, the coronoid process was transected. Three strips of the fascia lata were anchored to the muscle of the nasolabial fold through subcutaneous tunneling. The tension of the strips was adjusted by observing the shape of the nasolabial fold. When optimal tension was achieved, the temporalis muscle was sutured to the strips. The surgical results were assessed by comparing pre- and postoperative photographs. Three independent observers evaluated the photographs. RESULTS: The symmetry of the mouth corner was improved in the resting state, and movement of the oral commissure was enhanced in facial animation after surgery. CONCLUSIONS: The orthodromic transfer of temporalis muscle technique can produce prompt results by applying the natural temporalis muscle vector. This technique preserves residual facial nerve function in incomplete facial nerve palsy patients and produces satisfying cosmetic outcomes without malar muscle bulging, which often occurs in the turn-over technique.
ABSTRACT
Tissue engineering approaches for promoting the repair of peripheral nerve injuries have focused on cell-based therapies involving Adipose-derived stem cells (ASCs). The authors evaluated the effects of undifferentiated ASCs and of neurally differentiated ASCs on the regenerating abilities of peripheral nerves. We hope that this would demonstrate the feasibility of using adipose derived stem cells for peripheral nerve regeneration and provide clues regarding the use of adipose- derived stem cells. ASCs were isolated and cultured. Then the cells were cultured with neuronal induction agents for neural differentiation. ASCs and neurally differentiated ASCs were transplanted into sciatic nerve defects. After 12 weeks, the number and diameter of the myelinated fibers were measured and nerve conduction study was done. The extent of regeneration of myelinated fibers in the neurally differentiated ASCs transplanted group was greater than that in the ASCs transplanted group or the control group. However, thickness of myelin sheath and diameter of nerve fibers in the ASCs transplanted group were greater than those in the neutrally differentiated ASCs transplanted group or the control group. Nerve conduction study showed good recovery in the neurally differentiated ASCs transplanted groups. Muscles can atrophy and contract if denervation has started. It would be difficult to recover muscle function even if the nerve was reinnervated. Therefore, although neurally differentiated ASCs were found to have a greater functional effect than non-differentiated ASCs, time constraint is important when considering a method of ASCs transplantation.
