A comparison of delayed versus immediate reconstruction following lower-extremity sarcoma resection.

BACKGROUND: Identifying patients who may be at high risk for wound complications postsarcoma resection and reconstruction is essential for improving functional outcomes and quality of life. Currently, the effect of timing on sarcoma reconstruction has been poorly investigated. The purpose of this study was to compare outcomes of delayed and immediate reconstruction in the setting of sarcoma resection requiring flap reconstruction in the lower extremity. METHODS: A retrospective review of the senior author's sarcoma reconstruction patients from January 2005 to July 2017 was completed. All patients undergoing flap reconstruction of the lower extremity were included. Complications in the early postoperative period were compared between delayed and immediate reconstructive procedures. RESULTS: A total of 32 patients (7 delayed, 25 immediate) were included in this study. There was a significantly increased rate of overall complications (100% vs. 28.0%, P=0.001) and rate of hematomas (28.6% vs. 0.0%, P=0.042) in the delayed reconstruction group. Other complications including dehiscence, seroma, infection, venous thrombosis, and total/partial flap loss were also increased in the delayed reconstruction group, but this was not considered to be significant. CONCLUSIONS: This study suggests that delayed reconstruction following sarcoma resection of the lower extremity had a higher incidence of overall complications and hematoma formation. We emphasize the importance of early plastic and reconstructive surgeon referral and the necessity to closely monitor delayed reconstruction patients for complications.

Preservation of lower extremity spare parts using the University of Wisconsin solution.

The management of a mangled limb is a challenging endeavor. With the advancement in microsurgery, spare parts surgery (fillet flaps) has gained recent interest. In the context of lower extremity amputation secondary to trauma, viable spare parts can provide stump soft tissue coverage, potentially preserving critical length and obviating above-knee amputations. Commonly, spare parts surgery is performed in the acute setting but tissue preservation is sometimes necessary. The authors report their experience preserving a fillet flap of a mangled lower extremity for 48 h using the University of Wisconsin solution. A sole fillet flap and a split-thickness skin graft were harvested and preserved from the amputated lower extremity (based on the posterior tibial artery and vein). Stump coverage was achieved by anastomosing the fillet flap to the proximal posterior tibial artery and vein. This solution has not been previously described for preservation of fillet flaps.

Vascularized Tissue Reconstruction in Previously Irradiated Sarcoma Defects.

INTRODUCTION: Radiation therapy (RT) is recommended for appropriately selected sarcoma patients to minimize the risk of local recurrence and to maximize outcomes of disease-free survival and function. The purpose of this study was to confirm the safety of vascularized tissue reconstruction in recently irradiated sarcoma defects. METHODS: A retrospective review of all patients treated by the senior author for sarcoma reconstruction from January 2005 to July 2017 was performed. Two independent reviewers collected data from both electronic and paper medical records. Patients were included if they underwent flap reconstruction (pedicled or free) following sarcoma resection. The safety of neoadjuvant RT was compared with a control group with no previous irradiation using χ(2) analysis. RESULTS: Fifty-seven patients were included in the study; 35 patients were included in the preoperative RT group, and 22 patients were included in the control group (no previous irradiation). There was no significant difference in wound complications between the 2 groups (infection, dehiscence, hematoma, and seroma). Microvascular complications (arterial thrombosis, venous thrombosis, partial/total flap loss) were also comparable in the free tissue transfer subgroup. CONCLUSIONS: The current study demonstrates the safety of both pedicled and free flap reconstruction in previously irradiated sarcoma defects. Judicious selection of reconstructive technique and recipient vessels is crucial in obtaining optimal outcomes given the devastating effects of RT on native tissues.

Restoration of shoulder motion using single- versus dual-nerve repair in obstetrical brachial plexus injury.

OBJECTIVE The purpose of this study was to compare shoulder abduction and external rotation (ER) after single-nerve repair of the upper trunk alone versus dual-nerve repair of both the upper trunk and the suprascapular nerve. METHODS A retrospective chart review of a single surgeon's experience repairing obstetrical brachial plexus injuries between June 1995 and June 2015 was performed. Eight patients underwent repair of the upper trunk alone, and 10 patients underwent repair of the upper trunk and the suprascapular nerve. Shoulder abduction and ER ranges of motion (ROMs) (in degrees) were recorded preoperatively and postoperatively. Postoperative ROM and the difference in ROM gained after surgery were compared by independent t-test analysis. RESULTS The mean follow-up time was 161.4 weeks (range 62-514 weeks, SD 124.0 weeks). The mean patient age at the time of surgery was 31.3 weeks (range 19.9-47.0 weeks, SD 6.9 weeks). The mean postoperative shoulder abduction ROMs were 145.0° (range 85°-180°, SD 39.4°) after single-nerve repair and 134.0° (range 90°-180°, SD 30.3°) after dual-nerve repair (p = 0.51). The mean postoperative shoulder ER ROMs were 67.5° (range 10°-95°, SD 28.8°) after single-nerve repair and 72.0° (range 10°-95°, SD 31.3°) after dual-nerve repair (p = 0.76). CONCLUSIONS The authors found no difference in shoulder abduction and ER between patients who underwent single-nerve repair of the upper trunk alone and those who underwent dual-nerve repair of both the upper trunk and the suprascapular nerve.

Tendon Rupture and Tenosynovitis following Internal Fixation of Distal Radius Fractures: A Systematic Review.

BACKGROUND: Tendon-related complications after plate fixation of distal radius fractures can cause significant morbidity in the patient. This retrospective systematic review aims to report and compare the current rate of tendon rupture and tenosynovitis complicating the operative management of distal radius fractures. METHODS: A systematic literature search was performed to identify relevant articles reporting tendon complications after operative management of distal radius fractures. The search included published articles in three electronic databases-Ovid MEDLINE, EMBASE, and the Cochrane Library-starting from the establishment of each database to February of 2016. RESULTS: A total of 56 studies met the inclusion criteria, including 6278 patients. Overall tendon-related adverse events were reported in 420 patients (6.8 percent). The incidence of tendon rupture was 1.5 percent with volar plates and 1.7 percent with dorsal plates. The incidence of tenosynovitis was 4.5 percent with volar plates and 7.5 percent with dorsal plates. Individual tendon complications were reported with volar and dorsal fixation, respectively: extensor pollicis longus tenosynovitis (0.3 percent and 1.1 percent), extensor pollicis longus rupture (0.8 percent and 0.3 percent), flexor pollicis longus tenosynovitis (1.3 percent and 0 percent), flexor pollicis longus rupture (0.6 percent and 0.2 percent), flexor digitorum profundus/flexor digitorum superficialis tenosynovitis (1.2 percent and 1.3 percent), flexor digitorum profundus/flexor digitorum superficialis rupture (0.1 percent and 0 percent), extensor digitorum communis tenosynovitis (1.7 percent and 5.9 percent), and extensor digitorum communis rupture (0.05 percent and 1.3 percent). CONCLUSION: This systematic review provides an update on the literature regarding tendon-related complications in the management of distal radius fractures.

Prompt Referral in the Nonoperative Treatment of Obstetrical Brachial Plexus Injuries.

BACKGROUND: Prompt physical and occupational therapy is crucial in managing nonsurgical candidates with obstetrical brachial plexus injuries (OBPI). The objective of our study was to identify newborns suffering from nonoperative OBPI in need of a "fast-track" evaluation by a multidisciplinary team. METHODS: This is a retrospective review of patients with OBPI from June 1995 to June 2015. All nonsurgical candidates (Narakas class 1) were included in the study. The Gilbert score and the Medical Research Council grading system were used to measure shoulder and elbow function, respectively. The relationship between shoulder and elbow functional outcomes and time delay to consultation was studied using analysis of variance and Welch's tests. Various subgroups were studied based on OBPI risk factors: maternal diabetes, birth weight >4 kg, use of forceps, asphyxia, multiple comorbidities, and Apgar score at 1 and 5 minutes. RESULTS: A total of 168 patients were included in this study. Mean follow-up time was 313.8 weeks (minimum: 52; maximum: 1072; SD: 228.1). A total of 19 patients had an Apgar scores <7 at 5 minutes. Time delay between birth and the first consult to our clinic had an impact on shoulder outcome in the subgroup of newborns with Apgar scores <7 at 5 minutes. CONCLUSIONS: The subgroup of newborns with an Apgar score <7 at 5 minutes shows improved long-term shoulder function when promptly examined by an OBPI clinic. We recommend a "fast-track" referral for this time-sensitive population.

Heparin-induced thrombocytopenia and thrombosis as an under-diagnosed cause of flap failure in heparin-naive patients: a case report and systematic review of the literature.

BACKGROUND: Heparin-induced thrombocytopenia and thrombosis (HITT) is an immune complex mediated and potentially devastating cause of flap loss in microvascular surgery. HITT may be an under-reported cause of early-flap failure due to subclinical manifestations at the time of flap loss. A case report of a patient presenting with HITT-related flap failure and the results of a systematic literature review of the clinical presentation of HITT in microsurgery are presented here. CASE REPORT: A patient suffering from a chronic wound on the right medial malleolus was treated with an ALT flap, which was compromised by thrombosis. Multiple attempts to rescue the flap including thrombolysis, popliteal AV loop, and a second free flap were all unsuccessful. Six days following the initial procedure, a diagnosis of HITT was made following a positive HITT-antibody test as the cause of flap failure. METHODS: PubMed, MEDLINE, and EMBASE searches yielded 113 results, of which 6 met our criteria for manuscripts describing HITT in microsurgical procedures. RESULTS: Evaluation of the peer-reviewed literature describing HITT in microsurgery suggests that HITT-related flap failure occurs rapidly, more frequently in heparin-naïve patients, and in advance of systemic thrombosis and thrombocytopenia. CONCLUSIONS: Due to the rapid and unpredictable onset of HITT during microsurgery, we recommend maintaining an index of suspicion for HITT in flaps with otherwise unexplained early thrombosis. We also encourage hematology consultation, discontinuing heparin use and initiating alternate thromboprophylaxis in order to inhibit the potential for subsequent life-threatening systemic complications as well as improving the potential for delayed reconstructive success.

Unilateral absence of latissimus dorsi muscle.

Latissimus dorsi (LD) is the broadest muscle of the back responsible for extension and adduction of shoulder. The authors report a case of isolated unilateral absence of the latissimus dorsi muscle observed during an ablative surgical procedure and flap reconstruction. The left LD muscle was completely absent in our patient and no tendon fibers belonging to this muscle could be observable on further dissection. The surrounding muscle anatomy was normal and in place suggesting a developmental etiology for its absence. Awareness of this possible variation is of importance in considering reconstructive options.

Ageing midface: The impact of surgeon's experience on the consistency in the assessment and proposed management.

An individual's face undergoes numerous changes throughout life. Since mid-face aesthetic units are key areas for rejuvenation procedures, their comprehensive assessment is essential for the development of any aesthetic management plan. Despite the availability of many evaluation criteria for treatment of mid-face ageing, there are discrepancies existing in both assessment and management approaches. The goal of this study was to determine if there are any identifiable profiles of clinical judgements and approaches related to the level of surgeon's experience. Forty seven standardised non-digital and not altered natural size photographic images of patients' faces (front and profile) were presented to eight senior board certified plastic surgeons, eight junior non-board certified plastic surgeons and eight plastic surgery residents from an independent program. Surveyed physicians were 'blinded' from each other and asked to assess five different major features characterising ageing mid-face. An interclass correlation data analysis was performed and the Cronbach coefficient alpha values were computed for each category. Responses obtained from senior plastic surgeons were consistently characterised by higher Cronbach coefficient alpha values indicating higher concordance. The highest agreement levels were obtained for the assessment of rhytids and jowls across all groups and the lowest agreement levels were obtained for the assessment and recommendation of upper lip management. This study illustrated that discrepancies in clinical assessments and surgical management exist among surgeons involved in the aesthetic surgery of the mid-face ageing. It appears that the level of surgeon's experience significantly impacts the inter-rater reliability and consensus in assessment and treatment of mid-face ageing. The most senior plastic surgeons' assessment and recommendations had the highest level of concordance while the junior non-board certified plastic surgeons and the residents group produced variations with less consistency.

Desmoid tumors of the pediatric mandible: case report and review.

Desmoid tumors are benign fibrous neoplasms originating from the musculoaponeurotic structures throughout the body. These rare neoplasms have been shown to account in 0.03% of all cancers. Twenty-five percent of all desmoid tumors occur in children under 15 years of age. The infrequency of these tumors has limited studies to case reports and retrospective reviews dictating the authors recommended treatments and management. We present a case report of desmoid tumor involving the left mandible in a 14-month-old infant. His treatment course included 2 excisions, removal of the free rib graft secondary to persistence of the tumor, and wound dehiscence, and later a free fibular osteomyocutaneous flap for reconstruction. We then retrospectively reviewed all published data of desmoid tumor involving the pediatric mandible since 1950 to 2007 in the PubMed database. Forty cases have been reported, which had a M:F ratio of 1:1 with an average age of 5.3 (standard deviation [SD] +/- 4.5) years. There appeared to be left-sided predominance of desmoid tumors in the pediatric mandible with a ratio of 3:1. The mean size of the tumors was 4.6 cm (SD +/- 2.1) at the largest diameter. We have tabulated the relevant data of all the cases including the methods of treatment and recurrence. It is found that when compared with conservative management, radiation therapy, chemotherapy, and curettage or surgical local excisions as treatment options the most efficient treatment was partial mandiblectomy, which resulted in complete tumor dissipation with no tumor recurrence. In summary, this is the largest review of the pediatric desmoid tumor of the mandible to date where we provide for the first time an algorithm for the management and treatment of the pediatric desmoid tumor of the mandible.

Replantation surgery in Quebec: The bottlenecks to rapid care.

INTRODUCTION: Time delays resulting in prolonged ischemia have a significant impact on the successful reattachment of amputated body parts. No studies have addressed the issues surrounding delays from the time of the accident to the start of replantation surgery. The present paper identifies the bottlenecks that prolong the time before patients are able to gain access to a replant team. METHODS: A total of 50 patients underwent microsurgical replantation, because of traumatic amputation, at a university-based hospital from 1996 to 2003. The charts were analyzed to ascertain individual time intervals from the onset of injury until the beginning of replant surgery. RESULTS: The average length of time for patients who came directly to the replant centre was 3 h 40 min before surgery began. In contrast, for those referred from outlying hospitals, the elapsed time was 6 h 21 min. CONCLUSIONS: Two major bottlenecks were found. First, for patients who were referred from other health centres, delays were due to a lack of information as to where patients could receive appropriate replant surgery. Second, delays at the replant centre were primarily due to insufficient physical and human resources in the operating room.
