Comparison of split thickness skin graft versus full thickness skin graft for radial forearm flap donor site closure: A systematic review and Meta-analysis.

BACKGROUND: The radial forearm flap (RFF) is one of the most commonly used flaps in reconstructive surgery. Split-thickness skin grafting (STSG) has traditionally been used for closure of the forearm. However, full-thickness skin grafting (FTSG) has gained in popularity to achieve more satisfactory results. The aim of the study is to identify the best RFF donor site closure technique by comparing the functional and aesthetic outcomes of STSG and FTSG. METHODS: PubMed and EMBASE databases were queried. Only studies comparing complications rate, functional and aesthetic outcomes between STSG and FTSG were included. The primary outcome was graft failure rate. Secondary outcomes included the aesthetic result and functionality of the forearm/wrist. RESULTS: A total of 13 studies were included in this review, accounting for a total of 712 patients with mean age of 60.7 years. Overall, 348 patients underwent FTSG and 377 underwent STSG. The mean follow-up was 14.7 months. The rate of graft failure in FTSG was significantly higher compared to STSG (OR: 2.79, 95 % CI 1.38-5.65, p = 0.004). There was no significant difference in rate of tendon exposure (OR: 0.83, p = 0.65) and infection (OR: 1.37, p = 0.42). Regarding the aesthetic outcome, no significant difference between FTSG and STSG based on observer (SMD = -0.37, p = 0.17) and patient (SMD = -0.016, p = 0.93) assessment, respectively. Overall postoperative functional assessment showed a not severely impaired hand and arm function in both groups. Subjective evaluation of pain was similar between groups. CONCLUSION: FTSG is associated with higher risk of graft failure than STSG in RFF donor site closure, without significant improvement in aesthetic results.

Medial sural artery perforator free flap versus radial forearm free flap in oral cavity reconstruction and donor site morbidity.

OBJECTIVE: Radial Forearm Free flap (RFFF) is widely used in head and neck reconstruction, yet its donor site defect remains a significant drawback. The Medial Sural Artery Perforator Free Flap (MSAPFF) is considered an alternative flap to RFFF. This study aims to comprehensively analyze their characteristics, outcomes, and their impact on patient quality of life. METHODS: All patients who underwent oral cavity reconstruction using RFFF and MSAPFF between February 2017 and April 2023 were included in this study. Flap characteristics, outcomes and post-operative complications were recorded and compared. Subjective donor site morbidity, aesthetic and functional results, and quality of life were also analyzed. RESULTS: The study included 76 patients: 37 underwent reconstruction with RFFF, and 39 with MSAPFF. There was no significance difference between the RFFF and MSAPFF regarding the success rate (97.2% vs 97.4%), flap size (4.8 × 8.8 cm2 vs 5 × 9.8 cm2), hospital of stay (15.5 days vs 13.5 days) and recipient site complications (P > 0.05). However, MSAPFF showed larger flap thickness (P = 0.001), smaller arterial caliber (P = 0.008), shorter pedicle length (P = 0.001), and longer harvesting time (P < 0.001). No significant difference was observed between the pre-and postoperative ranges of wrist and ankle movements or in recipient site complications. MSAPFF showed a significant difference in donor site morbidity (P < 0.05). CONCLUSION: The MSAPFF is an excellent alternative to the RFFF for repairing oral cavity defects, with additional advantage of a well-hidden scar on the posterior calf, a larger flap thickness, accepted pedicle length and arterial caliber. However, one should consider the harvesting time and surgical skills required in comparison to the RFFF. CLINICAL RELEVANCE: The study highlights the importance of the MSAPFF as an alternative option for RFFF with less donor site morbidity and high success rate in oral cavity reconstruction and improved patient Quality of life after ablative surgery.

Donor-site morbidity following arthroscopic anterior cruciate ligament reconstruction using peroneus longus tendon autograft.

INTRODUCTION: Peroneus longus has proved to be a promising graft for ACL reconstruction due to its high tensile strength, and ease of harvesting. While multiple studies have assessed the functional outcomes of the knee after ACL reconstruction using peroneus longus autograft, we aimed to evaluated donor site morbidity among the Indian population. MATREIALS AND METHODS: This was a prospective, longitudinal, descriptive study conducted at a tertiary care hospital. Preoperative AOFAS and Karlsson-Peterson scores were obtained, and patients were followed up after surgery for a period of 6-months using the same scoring systems and strength testing with a hand-held Chatillon MSE-100-M dynamometer. Pedobarographs were done using Diers Pedoscan Plantar Pressure Measurement System on a subset of seven patients. RESULTS: 20 patients participated in the study. Mean AOFAS and Karlsson-Peterson scores pre-operatively were 99.7 ± 1.34 and 98.5 ± 4.62 respectively. On completing 6- months of follow-up these scores were found to be 95.6 ± 9.43 and 88.75 ± 18.42 respectively. Deterioration of mean evertor strength was noted at all follow-ups compared to the opposite side. Static pedobarographs showed significant decreased in total surface area of contact and pressure over the posterior aspect of the operated side by 3-months which improved later at 6-months. Dynamic pedobarographs showed decreased mean average plantar pressure while walking on the operated side and significant increase in mean surface area of contact of the operated side (191.886±22.678 cm2) at 6-months of follow-up compared to the opposite side (184.471 ± 22.218 cm2). Five patients showed deviation of the point of maximum pressure while walking on the operated foot making it lateral to the COP with increased lateral plantar/ medial plantar pressure ratio. CONCLUSION: While the use of peroneus longus tendon autografts in arthroscopic ACL reconstruction does not seem problematic on short-term subjective assessment, there is objective evidence in keeping with evertor weakness, weakness of first ray plantar flexion and possible ankle instability.

Comparing donor site morbidity in osteocutaneous radial forearm versus fibula free flap for mandibular reconstruction.

PURPOSE: The osteocutaneous radial forearm free flap has gained popularity as a less morbid option for oromandibular reconstruction compared to the fibular free flap. However, there is a paucity of data regarding direct outcome comparison between these techniques. METHODS: Retrospective chart review of 94 patients who underwent maxillomandibular reconstruction intervened from July 2012-October 2020 at the University of Arkansas for Medical Sciences. All other bony free flaps were excluded. Endpoints retrieved encompassed demographics, surgical outcomes, perioperative data, and donor site morbidity. Continuous data points were analyzed using independent sample t-Tests. Qualitative data was analyzed using Chi-Square tests to determine significance. Ordinal variables were tested using the Mann-Whitney U test. RESULTS: The cohort was equally male and female, with a mean age of 62.6 years. There were 21 and 73 patients in the osteocutaneous radial forearm free flap and fibular free flap cohorts, respectively. Excluding age, the groups were otherwise comparable, including tobacco use, and ASA classification. Bony defect (OC-RFFF = 7.9 cm, FFF = 9.4 cm, p = 0.021) and skin paddle (OC-RFFF = 54.6 cm2, FFF = 72.21 cm2, p = 0.045) size were larger in the fibular free flap group. However, no significant difference was found between cohorts with respect to skin graft. There was no statistically significant difference between cohorts regarding the rate of donor site infection, tourniquet time, ischemia time, total operative time, blood transfusion, or length of hospital stay. CONCLUSIONS: No significant difference in perioperative donor site morbidity was found between patients undergoing fibular forearm free flap and osteocutaneous radial forearm flap for maxillomandibular reconstruction. Osteocutaneous radial forearm flap performance was associated with significantly older age, which may represent a selection bias.

Prespinal Versus Conventional Hemicontralateral C7 Nerve Transfer in the Treatment of Total Brachial Plexus Roots Avulsion Injuries: A Retrospective Study With a Minimum Follow-Up Period of 4 Years.

PURPOSE: Contralateral C7 (CC7)-to-median nerve transfer has been commonly used to restore hand function in brachial plexus injury. To shorten the nerve graft, the prespinal route was described and achieved direct coaptation when combined with humeral shortening osteotomy. The limb was positioned at 0° shoulder abduction and neutral head position. Given our concern about donor-site morbidity when harvesting the whole CC7 nerve and tension across the neurorrhaphy site after mobilization, we aimed to describe our modified prespinal route and compare its outcomes and complications with the conventional hemi-CC7 transfer. METHODS: From 2004 to 2014, 39 patients with preganglionic total brachial plexus root avulsion injuries, with a minimum of 4 years of follow-up, were included. Overall, 20 and 19 patients underwent the conventional hemi-CC7-to-median nerve and hemi-CC7-to-lower trunk (LT) transfer through the modified prespinal route, respectively. The modified prespinal route was combined with bilateral clavicle shortening osteotomy to achieve direct coaptation to the LT at 45° shoulder abduction. RESULTS: The modified prespinal route showed the median period to achieve ≥M3 hand grip assessed in clinical follow-up was shorter (26.5 months vs 45.5 months), and a higher proportion of patients achieved ≥M3 hand grip recovery (63% vs 30%). One patient experienced symptomatic phrenic nerve injury; however, the hemidiaphragm fully recovered after 6 months. The long-term donor-site complication rate was 2.6%, including one sensory abnormality, and no permanent donor-site weakness after hemi-CC7 harvesting was observed. CONCLUSIONS: The modified prespinal route combined with clavicle osteotomy allowed direct coaptation to the LT and did not require head immobilization. It may allow a higher proportion of patients to achieve ≥M3 hand grip more quickly than conventional hemi-CC7 transfer. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Long-Term Donor-Site Morbidity Following Entire Sural Nerve Harvest for Grafting.

PURPOSE: The sural nerve is the autologous nerve used most commonly for grafting. However, recent studies indicate a high rate of complications and complaints after sural nerve removal. In this prospective study, we evaluated donor-site morbidity following full-length sural nerve harvesting on long-term follow-up. METHODS: Fifty-one legs from 43 patients who underwent complete sural nerve harvesting for brachial plexus reconstruction were included in the study. After an average of 5 years, with a minimum postoperative follow-up of 12 months, sensory deficits in the leg and foot were analyzed using 2.0-g monofilaments. Regions of sensory deficit were marked with a skin marker and photographed. Over these regions of decreased sensation, we tested nociception using an eyebrow tweezer. Patients were also asked about pain, cold intolerance, pruritis, difficulties walking, and foot swelling. RESULTS: Regions most affected (84% of patients) were over the calcaneus and cuboid. However, in these regions, nociception was preserved. Regions of decreased sensation extended to the calf region in 11 of 51 legs. In 13 patients, we also observed regions of decreased sensation on the proximal leg. In five feet, the sensation was entirely preserved. No patient had any complaints about pain, cold intolerance, itchiness, difficulties walking, or foot swelling. CONCLUSION: Decreased sensation with nociception preserved was most common along the lateral side of the foot over the calcaneus and cuboid. Removing the entire sural nerve produced no long-term complaints of pain. Sural nerve use appears safe. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Evaluation of Serum Albumin-Coated Bone Allograft for Bone Regeneration: A Seven-Year Follow-Up Study of 26 Cases.

We have previously reported that serum albumin-coated bone allograft (BoneAlbumin, BA) is an effective bone substitute. It improves bone regeneration at the patellar and tibial donor sites six months after harvesting bone-patellar tendon-bone (BPTB) autografts for primary anterior cruciate ligament reconstruction (ACLR). In the present study, we examined these donor sites seven years after implantation. The study group (N = 10) received BA-enhanced autologous cancellous bone at the tibial and BA alone at the patellar site. The control group (N = 16) received autologous cancellous bone at the tibial and blood clot at the patellar site. We evaluated subcortical density, cortical thickness, and bone defect volume via CT scans. At the patellar site, subcortical density was significantly higher in the BA group at both time points. There was no significant difference in cortical thickness between the two groups at either donor site. The control group's bone defect significantly improved and reached the BA group's values at both sites by year seven. Meanwhile, the bone defects in the BA group did not change significantly and were comparable to the six-month measurements. No complications were observed. There are two limitations in this study: The number of patients recruited is small, and the randomization of the patients could have improved the quality of the study as the control group patients were older compared to the study group patients. Our 7-year results seem to demonstrate that BA is a safe and effective bone substitute that supports faster regeneration of donor sites and results in good-quality bone tissue at the time of ACLR with BPTB autografts. However, studies with a larger number of patients are required to definitively confirm the preliminary results of our study.

Complications of peroneus longus tendon harvesting: a retrospective review of 82 cases.

OBJECTIVE: Peroneus longus tendon (PLT) has become a reliable autologous graft option for various ligament reconstructions. But there are potential risks and complications associated with its use as a graft. This retrospective study aimed to examine the complications and donor site morbidity following PLT harvesting. PATIENTS AND METHODS: A retrospective review was performed on an institutional digital patient database, and all patients who underwent ligament reconstruction using PLT autograft were identified. Intraoperative, early, and late complications were reviewed using digital patient notes and patients underwent a complete physical examination during their final follow-up. Ankle function was assessed using the AOFAS score, and manual ankle muscle testing was performed on both sides. Sural nerve iatrogenic injury was evaluated with a dermatomal light touch examination. Cosmetic satisfaction due to incision scar and footwear complaints were also assessed. RESULTS: 82 patients (74 male, eight female) with a mean age of 31.9 ± 10.4 years (range, 16-66) were included in the final analysis. The mean follow-up time was 46.6 ± 30.3 months (range, 6-109). The mean AOFAS score for the donor side was 98.7 ± 3.3 (range, 87-100), and the contralateral side score was 100, with manual muscle testing graded as 5 in all movements and similar to the contralateral side. Fifteen patients (18.3%) had hypoesthesia over the dorsolateral aspect of the foot distal to the incision scar, two patients (2.4%) had hyperalgesia over the distal incision scar, and one patient (1.2%) had mild ankle instability. There were two cases (2.4%) of compartment syndrome, both of which were treated with fasciotomy and had complete regression of symptoms after 5 days. One patient (1.2%) had a transient peroneal nerve injury and foot drop that resolved in the sixth month. CONCLUSIONS: The results of this retrospective study suggest that harvesting the PLT is associated with a high rate of complications and donor site morbidity. The most common complication was hypoesthesia around the lateral side of the foot, although the ankle functions were not affected significantly. Two cases of compartment syndrome and one transient peroneal nerve injury were observed. Care should be taken while harvesting PLT autograft, and it should be kept in mind that peroneal nerve injury might occur. LEVEL OF EVIDENCE: Level IV, retrospective case series.

In-Situ 'Divide' and 'Deliver': A Simple Technique to Preserve Nerves in Chimeric Anterolateral Thigh Flap Harvest.

Anterolateral thigh (ALT) flap is the workhorse for reconstruction in head and neck post cancer excision. Chimeric multi-paddle flaps are useful for composite defects involving skin, mucosa, and soft tissue. The nerve to vastus lateralis (VL) runs along the pedicle, frequently interdigitating with it or the perforators. Sometimes, the nerve may be preserved during harvest but needs to be sacrificed frequently, leading to increased donor site morbidity. We recommend a simple technique to preserve the nerve, wherein the skin paddles or chimeric components are divided in-situ and manipulated around it without causing injury. This technique was used in 27 cases over 5 years. All involved nerves, perforators and pedicles were preserved. The technique can be extended to any flap harvest with multiple perforators with nerves in proximity, when multiple skin islands are desired.

Donor site morbidity of calcaneal, distal tibial, and proximal tibial cancellous bone autografts in foot and ankle surgery. A systematic review and meta-analysis of 2296 bone grafts.

PURPOSE: This study aims to report on the safety and donor site morbidity of the distal lower extremity (calcaneal, proximal, and distal tibial) cancellous bone autografts. We summarized the findings in a comprehensive infographic illustration. We are unaware of any similar meta-analyses to date. METHODS: Following the PRISMA guidelines, two independent investigators searched MEDLINE (PubMed), EMBASE, SCOPUS, Google Scholar, and Cochrane databases in December 2020 using the following keywords and their synonyms: ("bone graft", "donor site morbidity", "calcaneal graft", "proximal tibia graft", and "distal tibia graft"). Besides, the reference lists from previous review articles were searched manually for eligible studies. The primary outcomes of interest were (1) chronic pain, (2) fracture, and (3) infection, whereas the secondary outcomes were (1) neurological complications, (2) sensory disturbance and hypertrophic scars, (3) other complications such as shoe-wear difficulties and gait disturbance. Inclusion criteria were: studies on complications and adverse events of lower extremity bone autografts (calcaneal, proximal tibial, and distal tibial bone autografts) reporting at least one of the desired outcomes. Studies not reporting any of the outcomes of interest or if the full text is not available in English were excluded. Studies reporting on bone marrow aspirate or autografts for non-orthopedic indications were also excluded. RESULTS: After the removal of duplicates, a total of 5981 studies were identified. After screening those records, 85 studies remained for full-text assessment. Out of those, 15 studies qualified for the meta-analysis with a total of 2296 bone grafts. Out of those grafts, 1557(67.8%) were calcaneal grafts, 625 (27.2%) were proximal tibial grafts, and 114 (5%) were distal tibial grafts. In calcaneal bone grafts, there were 28 cases of chronic pain [1.97%, CI:1.10-2.50%, I2 = 66%], 5 fractures [0.32%, CI: 0.10-0.60%,I2 = 0%], 20 sural neuritis [1.28%, CI:0.70-1.80%, I2 = 0%), and no wound infections. In proximal tibial grafts there were 13 cases of chronic pain [2.08%, CI: 1.01-3.2%, I2 = 34.5%], 1 fracture [0.16%, CI:0.10-0.50%, I2 = 0%], and 3 superficial wound infections [0.48%, CI: 0.10-1.01, I2 = 0%]. In the distal tibial grafts there were no cases of chronic pain or wound infections, 1 fracture [0.90%, CI: 0.80-2.6%, I2 = 0%], and 5 saphenous neuritis [4.5%, CI: 0.70-8.40%, I2 = 65%]. CONCLUSION: Calcaneal, distal tibial, and proximal tibial bone autografts are safe with a low rate of overall and major complications. We report an overall complication rate of 6.8%, which is less than half of that previously reported for iliac crest grafts. The authors recommend using distal lower extremity grafts for foot and ankle primary surgeries instead of iliac crest grafts when indicated. Clinical trials with a large sample size are required.

The Use of Semi-Absorbable Mesh and its Impact on Donor-Site Morbidity and Patient-Reported Outcomes in DIEP Flap Breast Reconstruction.

BACKGROUND: This study aimed to evaluate the impact of semi-absorbable mesh on donor-site morbidity and patient-reported outcomes in deep inferior epigastric perforator (DIEP) flap breast reconstruction. METHODS: We conducted a retrospective cohort study of all patients who had DIEP flap breast reconstruction in our department from July 2007 to March 2019. Patients were invited to a comparative follow-up visit and grouped according to donor-site closure: primary fascial closure (the no-mesh group) and fascial reinforcement with semi-absorbable mesh in a subfascial position (the mesh group). The primary outcome of interest was donor-site morbidity, including bulging, hernia formation and rectus abdominis muscle strength. We also surveyed, surgical site complications and patient-reported outcomes using Patient and Observer Scar Assessment Scale v2.0 and BREAST-Q© version 2.0. RESULTS: A total of 191 patients had received DIEP flap breast reconstruction. Eighty-five patients (44.5%) with 108 DIEP flaps (53 patients in the mesh group and 32 patients in the no-mesh group) were included in the study. The mean BMI of the patients was significantly higher in the mesh group (mesh group, 26.9 vs. no-mesh group, 25.0, with p = 0.03). The incidence of hernia was significantly reduced in the mesh group (mesh group, 2.8% vs. no-mesh group, 13.5%, with p = 0.03). The incidence of bulging and the extent of rectus abdominis muscle strength were similar for both groups. Operative surgical site complications were reduced in the mesh group (mesh group, 7.5% vs. no-mesh group, 18.8%). There was no difference in patients' physical well-being and satisfaction with the donor site between groups. Patient-reported scar outcome was significantly better in the no-mesh group (p < 0.001). CONCLUSION: Our novel method of donor-site closure with semi-absorbable mesh in a subfascial position for reinforcement of the anterior rectus fascia on the DIEP donor site is safe. It has no negative impact on surgical site complications and patient-reported outcomes, while reducing the incidence of hernias on the donor-site in DIEP flap breast reconstruction.

Long-term donor-site morbidity after thumb reconstruction with twisted-toe technique.

BACKGROUND: Traumatic thumb loss is a serious injury affecting patient´s ability to work and participate in activities of daily life. The main goal for a plastic surgeon is to restore hand grip, often by microsurgical methods. However, patients should be informed of all effects associated with tissue harvesting. The aim of the study was to assess the impact on donor foot and gait cycle in patients who have undergone thumb reconstruction using twisted-toe technique modified by Kempný. MATERIAL AND METHODS: Twelve patients participated in the study: all suffered a thumb loss between the years 2003 and 2011 and the twisted-toe technique for thumb reconstruction was utilized. The changes in foot pressure distribution and lower extremity joint loading were evaluated. RESULTS: The differences in total maximal plantar pressure, pressure time integral, contact area, and maximum force between the affected and non-affected foot were statistically significant (P 0.1). No significant differences of temporal gait parameters between the affected and non-affected extremity were observed; however, statistically significant differences in kinetics parameters, frontal ankle and knee moments were detected. CONCLUSION: Donor limb functionality and anatomical disability were assessed using pedobarography systems and 3D-gait analysis. The recorded differences in plantar pressure distribution (increased pressure in I., IV. and V. metatarsal areas) and overload of the medial compartment of the knee joint were the most significant findings. Therefore, wearing individually adapted shoe insoles as prevention of osteoarthrosis might be beneficial for patients after thumb reconstruction by a twisted-toe technique.

Full cheek defect reconstruction using ALTF versus RFF: Comparison of quality of life, clinical results, and donor site morbidity.

OBJECTIVES: This study aimed to compare the quality of life (QOL) of patients, clinical results of the recipient site, and morbidities of the donor site between the use of free anterolateral thigh flaps (ALTFs) and radial forearm flaps (RFFs) for reconstruction of full cheek defects following tumor resection. MATERIALS AND METHODS: We retrospectively reviewed 52 patients who underwent reconstruction of full cheek defects using free ALTFs and free RFFs following tumor ablation at our center. The range of mouth opening, speech, swallowing, facial appearance, donor site complications, and subjective symptoms based on the University of Washington Quality of Life (UW-QOL) questionnaire findings were assessed in the ALTF and RFF groups at 3, 12, and 36 months after surgery. RESULTS: Quality of life, range of mouth opening, facial appearance, mood and anxiety, donor site appearance, subjective feeling, and functional impairment were better in the ALTF group than in the RFF group based on the physical examination findings and questionnaire scores. CONCLUSION: This study found better QOL and better functional results at the recipient site and minor morbidities at the donor site with the use of free ALTFs in the reconstruction of full cheek defects.

Donor site aesthetics and morbidity after DIEP flap breast reconstruction-A retrospective multicenter study.

The deep inferior epigastric artery perforator flap (DIEP) has gained widespread popularity in autologous breast reconstruction due to its natural aesthetic results and muscle-sparing design. However, donor site results regarding aesthetic outcome are often less favorable. We therefore aimed to identify crucial factors that might increase the risk for abdominal bulging and an impaired aesthetic appearance. We conducted a multicenter study evaluating all patients receiving autologous breast reconstruction using a DIEP flap between 2013 and 2017. Medical records were analyzed with special attention to flap technique, number of perforators, localization of perforator, and donor site complications. In addition, the aesthetic appearance of the abdominal donor site was evaluated by blinded clinicians at one-year follow-up. A total of 242 patients underwent DIEP flap breast reconstruction. Abdominal bulging occurred in 7%. Further subgroup analysis revealed a significant correlation between abdominal bulging and two or more perforators (P = .003), the use of lateral row perforators (P = .009), and a higher BMI (P = .002). Obesity (P = .003) and higher patient's age (P = .003) could be identified as risk factors for an undesirable appearance of the donor site. We recommend the use of a medial-row single perforator whenever possible in order to optimize donor site morbidity and decrease the risk of abdominal bulging. Proper patient selection and careful donor site closure following a standardized approach should be performed to limit the risk of aesthetically undesirable results.

Predicting adequacy of free quadriceps tendon autograft, for primary and revision ACL reconstruction, from patients' physical parameters.

PURPOSE: Free quadriceps tendon autograft (QTA) has gained popularity for both primary and revision ACL reconstruction. The aim of this study is to measure the dimensions of quadriceps tendon and determine its correlation with patient's height, weight and BMI. This is to provide a guide for patients and surgeons in predicting the suitability of QTA for ACL reconstructions. METHODS: A cross-sectional study in which the length and thickness of the quadriceps tendon was measured in 51 Caucasian patients who underwent primary total knee arthroplasty. Exclusion criteria include non-Caucasians and previous tendon pathology. Patients were selected from routine elective total knee arthroplasty list. Tendon length is taken from musculotendinous junction to its insertion. Thickness was measured at midpoint and at distal insertion. Patients' height, weight and BMI were recorded. The correlation between patient physical parameters and tendon dimensions were determined. RESULTS: Subjects' median age was 65 years (range 44-87), with 34 females and 17 males. Median length of the tendon was 9 mm (range 70-110), and median insertional thickness was 9 mm (7-10 mm). Median thickness at midpoint was 7 mm (range 4-10 mm). There was moderately positive correlation between subjects' height and tendon length (correlation coefficient 0.50), and also between weight and tendon length (correlation coefficient 0.47). There was no significant correlation between subjects' BMI and the tendon length. There was also no significant correlation between tendon thickness and subject's physical parameters. CONCLUSION: This study has shown that most patients could provide adequate QTA for ACL reconstruction. It also points to the fact that no investigation is required to predict the adequacy of QTA. Though further studies with larger sample size are required to confirm this, clinician can rely on analysing patients' physical parameter in predicting the adequacy of QTA for ACL reconstruction.

Long-Term Donor-Site Morbidity After Free, Nonvascularized Toe Phalanx Transfer for Congenital Differences of the Hand.

PURPOSE: Toe phalanx transplantation is a well-established technique for addressing bony deficiency in the reconstruction of hypoplastic digits in patients with congenital differences of the hand. Prior studies have commented on varying degrees of donor-site morbidity, although assessment of morbidity with validated outcome scores is lacking. This study seeks to evaluate donor-site morbidity after toe phalanx harvest using validated outcome measures. METHODS: We identified all children who underwent free, nonvascularized toe phalanx transfer to the hand at our institution from 2001 to 2011. We administered the Oxford Ankle Foot Questionnaire for Children (OXAFQ-C) and the Foot and Ankle Ability Measure (FAAM) to all patients, scaling results according to published scoring instructions. RESULTS: Thirty-six patients with 83 toe phalanx transfers were able to be contacted, with a mean follow-up of 5.3 years (range, 18 months-11.2 years). The results of the OXAFQ-C showed mean scores of 99.96% (Physical), 100% (School and Play), and 96.01% (Emotional). The FAAM mean scores were 99.08% (Sports) and 99.17% (Activities of Daily Living). There were no lower extremity complications during the study period. CONCLUSIONS: In contrast to varying degrees of donor-site morbidity reported in the current literature, this study demonstrates that toe phalanx harvest causes almost no measurable lower extremity morbidity or dysfunction over the mid- to long-term.

Corticoperiosteal medial femoral condyle flap for recalcitrant nonunion in ankle and foot: Outcomes and radiological evaluation of donor site morbidity.

BACKGROUND: The aim of this study was to evaluate the effectiveness and safety of free corticoperiosteal medial femoral condyle (MFC) flap for ankle, hindfoot and midfoot reconstruction in patients with recalcitrant nonunion. METHODS: Patients who underwent ankle and foot reconstruction using the MFC flap at our clinic were recruited for assessment of the union rate, time to union and functional outcome. Furthermore, a clinical and radiological examination of the donor knee was performed using both computed tomography and magnetic resonance imaging. RESULTS: Thirteen patients with a mean follow-up time of 2.5 years were included; 10 of them had a previously failed ankle and foot arthrodesis. Union was achieved in 11 patients in an average time of 10 months after MFC flap surgery. Donor site morbidity was minor with no radiological evidence for soft tissue or bone complication. CONCLUSION: MFC flaps are a useful and safe reconstructive tool and may be considered after failed ankle and foot arthrodesis.

Minimally invasive fascia lata harvesting in ASCR does not produce significant donor site morbidity.

PURPOSE: The aim of this study was to prospectively evaluate donor site morbidity in arthroscopic superior capsular reconstruction using a minimally invasive harvested fascia lata autograft. METHODS: Fifteen consecutive patients underwent arthroscopic superior capsular reconstruction by the senior author using a fascia lata autograft harvested in a minimally invasive fashion. All patients were prospectively evaluated at 1 week, 6 and 18 months postoperatively. The subjects' body mass index, age, actual or previous corticosteroid therapy history and active smoking habits were evaluated. Functional outcomes were assessed by the non-arthritic hip score applied to the harvested and contralateral thighs. Every patient completed standardized subjective satisfaction questionnaires at all evaluations. The median patient age was 65.5 years (range 47-77). Nine patients (60%) were females, and six (40%) were males. One patient (6.7%) was within the normal range of weight, nine (60%) were overweight, four (27%) were obese, and one (6.7%) was extremely obese. Two patients (13%) were active smokers. No patients had an active or previous record of corticosteroid therapy. No patients required postoperative lower limb physical therapy. RESULTS: In terms of overall and cosmetic satisfaction, most patients reported that they were satisfied or very satisfied at all evaluations, and the proportion of very satisfied patients increased over time (p < 0.001). The harvested thigh's functional scores were 91% (p = 0.003) and 94% (p = 0.008) of the healthy thigh's score at 6 and 18 months, respectively. The complications reported were mild, and their proportions decreased in the first 18 months after surgery (p = 0.04). CONCLUSIONS: The minimally invasive fascia lata harvesting technique for arthroscopic superior capsular reconstruction leads to donor site satisfactory subjective results and good functional outcomes at 18 months after surgery. According to these findings, donor site morbidity is not a valid argument against the use of this autograft for arthroscopic superior capsular reconstruction. LEVEL OF EVIDENCE: Case series, level IV.

Impact of wound closure on fibular donor-site morbidity: a meta-analysis.

BACKGROUND: Vascularized free fibular flaps have been the "workhorses" for reconstruction of many kinds of bone defects. Nevertheless, there is no consensus regarding the optimal wound closure method for fibular donor sites. This study aimed to compare prognostic outcomes of primarily closures (PC) and skin grafts (SG) for fibular donor sites. METHODS: Studies regarding donor-site outcomes of PC versus SG in patients undergoing free fibular flap procedures were included. Two authors individually searched PubMed, Web of Science, EMBASE, Cochrane Library and clinicaltrials.gov up to February 2019, extracted the data and assessed quality of each selected article. Ultimately, The incidences of donor-site morbidities were evaluated. RESULTS: Five studies with a total of 119 patients were included in our analysis. No significant differences were found with respect to the rates of donor-site problems between the PC and SG groups. CONCLUSIONS: Fibular flap patients undergoing PC and SG wound closures may have similar donor-site outcomes. Additional large-scale studies are necessary to draw a solid conclusion.

Donor site complications following anterior iliac crest bone graft for treatment of distal radius fractures.

INTRODUCTION: In distal radius fractures with metaphyseal comminution, bone grafting or the use of a bone substitute may be necessary. Harvesting autologous iliac crest bone graft for other orthopedic procedures has complications. The aim of this study was to evaluate the complication rate after harvesting a small amount of bone as used for the treatment of radius fractures. PATIENTS AND METHODS: Patients treated in a single level I trauma center with surgical treatment for distal radius fracture with iliac crest bone graft between January 2008 and December 2012 were included in this retrospective study. Patients' records were evaluated and clinical evaluation was performed at follow-up. RESULTS: 42 patients (20 females, 22 males, mean age 56.3 ± 15.9 years) were included in this study. Follow-up was mean 6.3 ± 1.2 years. Only minor complications such as hematoma could be identified; in one patient, revision surgery for bleeding was performed. No nerve injuries, long-term pain, fractures, infections or wound healing disturbances could be seen. The use of a drain of hemostyptics, the type of wound closure or pattern of harvested bone did not influence complication rate. CONCLUSION: This study shows that harvesting a small amount of iliac crest bone graft for the treatment of distal radius fractures is a safe procedure with a very low complication rate.
