RESUMO
PURPOSE: Wide awake local anesthesia no tourniquet (WALANT) is gaining popularity with flexor tendon repair. We hypothesized that results of zone II flexor tendon repair performed under WALANT would be superior to those performed under general anesthesia (GA). METHODS: A randomized controlled trial was conducted to compare results of repair of zone II flexor tendon lacerations under WALANT versus GA. Following sample size estimation, 86 digits were included and randomized into two groups. All surgeries were performed by a single surgeon using a six-stranded core stitch and running epitenon suture. All patients followed the same early active rehabilitation protocol. The primary outcome was recovery calculated using the Strickland and Glogovac criteria. Secondary outcomes included rupture rate, complication rate, and Disabilities of the Arm, Shoulder, and Hand (DASH) score. All outcomes were reported at the 6-month visit for all patients. RESULTS: Of the 86 digits, three were lost to follow-up. Analysis was performed on 43 digits in the WALANT group and 40 in the GA group. Demographic characteristics including age and sex were comparable in both groups. Rupture of the repair occurred in two digits in each of the WALANT and GA groups. An excellent or good outcome was achieved in 49% and 56% of the digits in the WALANT and GA groups, respectively. This difference was not statistically significant. DASH scores averaged 12.9 and 8.4 for the WALANT and GA groups, respectively. CONCLUSIONS: WALANT may not be superior to GA in regards function, rates of rupture, and patient-reported outcomes in repair of zone II flexor tendon lacerations. Surgeons can be confident in choosing either technique if rigorous patient selection, sound surgical technique, and proper hand therapy are employed. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.
RESUMO
BACKGROUND: Septic necrosis of the femoral head and neck in children represents a challenging problem. Several reconstructive techniques have been described but with disappointing long-term results. Vascularized epiphyseal transfer utilizing the proximal fibula have been successfully used for reconstruction of the proximal humerus and distal radius and only scarcely used for hip reconstruction. This cohort represents the largest reported series of epiphyseal transfer for hip reconstruction following septic necrosis in children. METHODS: A total of 18 patients with an average age at surgery of 5.4 years were included. The average follow-up was 3.6 years (range 2.3 to 6.8 y). RESULTS: Transient postoperative foot drop was observed in 4 patients. Radiographic resorption of the transferred fibula occurred in 2 cases. Longitudinal growth averaged 7.3 mm/year, and the physis width increased by an average of 2.7 mm/year. The rate of longitudinal growth was fastest after the age of 10 years (18.5 mm/y), which coincides with the pubertal growth spurt. All successful transfers had an open growth plate on final follow-up radiographs. Ten patients had limb length discrepancy of an average 2.8 cm (range 1 to 8 cm). Thirteen patients had satisfactory functional according to the criteria of Hunka et al. Three patients had unsatisfactory results; one had painful nonunion at the fibula-femur junction, and the other two had limited flexion range of 45 degrees. The average postoperative neck-shaft angle was 96.4 degrees which decreased by an average of 8 degrees at the final follow-up. Three patients underwent a valgus subtrochanteric osteotomy to correct a severe varus deformity. The final neck-shaft angle correlated significantly with the functional results where it averaged 96 degrees in the satisfactory group and 57 degrees in the unsatisfactory group. CONCLUSION: Vascularized epiphyseal transfer presents a promising treatment for children with septic necrosis of the femoral head and neck in whom other methods have failed to provide satisfactory long-term results. We recommend the procedure be done before the age of 5 years for optimum results. LEVEL OF EVIDENCE: Level-IV.

INTRODUCTION: Congenital pseudarthrosis of the fibula is not an uncommon condition to accompany congenital pseudarthrosis of the tibia. Persistence of the fibular pseudarthrosis has been linked to inferior outcomes including tibial union and alignment, refractures, and ankle alignment. In this report, we present the results of a pedicled periosteal propeller flap technique for the treatment of fibular pseudarthrosis. METHODS: Ten children with an average age at surgery of 5.3 years who had congenital pseudarthrosis of both tibia and fibula were studied. The tibia was treated with free vascularized fibular grafting, and the ipsilateral fibula was treated with a technique after resection of the pseudarthrosis. A periosteal flap from the proximal healthy part of the fibula is harvested off the bone, rotated 180° based on a branch from the peroneal vessels to cover the fibular defect and fashioned in the form of a tube filled with bone fragments. RESULTS: The periosteal flap size ranged from 5 to 7 cm. Follow-up averaged 37.2 months. The tibia was united in all cases; in 2 of them, refractures occurred and healed with conservative management. The fibula was united in 8 cases. At final follow-up, 5 cases showed residual tibial deformity, and 5 showed residual ankle deformity. Average leg-length discrepancy was 1.4 cm (0-3 cm). CONCLUSION: The pedicled periosteal propeller flap presents a useful new technique for managing concomitant congenital fibular pseudarthrosis.

BACKGROUND: Late presenting cases of congenital pseudarthrosis of the tibia, are further complicated with severe shortening. Limb length discrepancy (LLD) cannot be corrected by vascularized fibular grafting and the use of Ilizarov distraction is associated with a high rate of complications. The aim of this study was to report the long-term follow-up of a combined technique previously published under the name "telescoping vascularized fibular graft". MATERIALS AND METHODS: Eleven patients operated at an average age of 10.2±3.2 years were reviewed. All cases were Crawford type IV affected by neurofibromatosis 1. Nine patients had an average of 4.3 previous operations. Preoperative LLD averaged 7.9±2.5 cm. RESULTS: Follow-up averaged 10±5.4 years. Seven cases (63.6%) reached skeletal maturity before final follow-up. Primary union was achieved in all cases after an average of 7.2±1.3 months. Full weightbearing was possible after an average of 10.6±2.2 months. Recurrent stress fractures occurred in 9 cases (81.8%) and healed with casting in 6 cases and required internal fixation in 3 cases. Eight cases (72.8%) developed tibial shaft deformities, mainly procurvatum that required corrective osteotomy in 2 cases. Final LLD averaged 2.7±1.3 cm. Complete tibialization of the graft was achieved after an average of 17.0 ± 3.6 months. Valgus deformity of the ipsilateral ankle averaged 12.4 degrees±7.5. CONCLUSION: The presented technique avoids osteotomy of the diseased bone and allows simultaneous treatment of the pseudarthrosis and correction of shortening. Compared with conventional bone transport, it requires shorter time of frame application and therefore better patient tolerability because there is no waiting for consolidation of the regenerate. The dis-impaction of the doweled fibula occurs proximally, allowing the less active site located at the distal aspect of the pseudarthrosis to heal without displacement. A shortcoming of the presented technique is the more propensity for axial deviation and refractures that seldom require surgery. LEVEL OF EVIDENCE: Level-IV.

PURPOSE: The role of primary surgery in delayed presenting cases of brachial plexus birth injury is still debated. The purpose of this study was to evaluate the results of brachial plexus reconstruction performed at the age of ≥12 months. METHODS: Twenty-nine cases were included. Five cases had upper (C5-6) palsy, 4 had upper/middle (C5-7), and 20 had total (C5-8 and T1) palsy. RESULTS: The age at the time of primary surgery was an average of 15.6 months. The brachial plexus was formally explored and neurolysis, grafting, and neurotization were used in different combinations. Exploration revealed that 27% of the roots were avulsed and 32% were ruptured. The follow-up was an average of 7.9 years. Generally, the best functional recovery was elbow flexion followed by shoulder external rotation. Satisfactory shoulder abduction (≥6 on the Toronto Active Movement Scale [TAMS]) was achieved in 31% of cases. The abduction range was an average of 79° ± 35°; 50° in upper palsy, 103° in upper/middle palsy, and 82° in total palsy. Shoulder external rotation ≥6 on the TAMS was achieved in 62% of cases. External rotation range was an average of 58° ± 29°; 78° in upper palsy, 68° in upper/middle palsy, and 52° in total palsy. Elbow flexion and extension of ≥6 on the TAMS were achieved in 69% and 58% of cases, respectively. Wrist flexion and finger flexion of ≥6 on the TAMS were achieved in 35% and 12.5%, whereas wrist and finger extension of >6 on the TAMS were achieved in 25% and 4% of cases, respectively. CONCLUSION: In the delayed presentation of brachial plexus birth injury, brachial plexus reconstruction results in good functional recovery of elbow flexion and shoulder external rotation but modest functional recovery of finger flexion and wrist extension. The rate of functional recovery of the elbow flexion was similar following nerve grafting and transfer. Nerve transfer for shoulder external rotation should be considered even in infants with available roots for grafting. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: We compared the arthroscopic wafer procedure (AWP) and ulnar shortening osteotomy (USO) for treatment of idiopathic ulnar impaction syndrome in terms of clinical, functional improvement and time of return to work. METHODS: This single-center study was conducted at an academic level 1 referral center between 2014 and 2020. Sixty patients with idiopathic ulnar impaction syndrome were prospectively randomized to treatment with either AWP or USO. At the final follow-up, patients were evaluated by the Disabilities of the Arm, Shoulder, and Hand; the Modified Mayo Wrist Score; the visual analog scale for pain; wrist range of motion; and grip strength. Also, the time of return to work and complications were reported. RESULTS: The mean follow-up periods were 22 ± 5.7 months in the AWP group and 21.1 ± 5.3 months in the USO group. All patients in the USO group achieved union by 12 weeks. At the final follow-up, there were no statistically significant differences in the outcome measures (Disabilities of the Arm, Shoulder, and Hand score; Modified Mayo Wrist Score; visual analog scale score; range of motion; and grip strength) in either group. Fewer complications and an earlier return to work were observed in the AWP group. CONCLUSIONS: Both techniques yielded comparable outcomes, with earlier return to work, a lower incidence of complications, and fewer secondary procedures in the AWP group. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

OBJECTIVE: To compare ultrasound- (US), fluoroscopy- (FL), and palpation-guided contrast injection techniques used for dorsal radio-carpal wrist MRA. MATERIALS AND METHODS: Patients with chronic wrist pain were randomized as to which injection technique they underwent into three groups of 50 participants. Dorsal radio-carpal contrast injection was performed under US, FL guidance (one radiologist for each), or palpation guidance by an orthopedic surgeon. The three techniques were compared by procedure time, success rate, number of attempts needed, frequency and grade of extravasation, joint distension, and MRA image quality. Additionally, any change from baseline wrist pain was recorded using the visual analog scale (VAS) at five time points (immediately, 8 h, 24 h, 48 h, and 1 week) after injection. RESULTS: One hundred and fifty patients (83 males and 67 females; mean age 29 ± 6.5 years) were included. Success rates for US- and FL-guided injections were 100%, while palpation-guided approach was significantly less successful (72%) (P = 0.02) with significantly more frequent extravasation (56%)(P < 0.001). US guidance was the least time-consuming (6.5 ± 1.6 min) compared to FL guidance (12.5 ± 1.9 min) and palpation guidance (8 ± 1.2 min) (all P < 0.001). The mean number of joint puncture attempts was significantly lower with imaging-guided techniques (1.1 ± 0.24 and 1.2 ± 0.4 for US and FL, P = 0.23) compared to palpation-guided one (1.6 ± 0.8) (P = 0.007). The largest increases in baseline-pain were 8-h post-injection, and US guidance was the least painful at all-time points (all P < 0.05). Joint distension and image quality were significantly better with imaging-guided techniques (P < 0.001 and P = 0.003). CONCLUSIONS: US-guided radio-carpal injection is a less time-consuming, more tolerable, and successful radiation-free method when compared to FL guidance. Palpation-guided injections require multiple attempts to enter the joint with high failure rates and frequent extravasation.

BACKGROUND: Traumatic brachial plexus injuries in children represent a definite spectrum of injuries between adult and neonatal brachial plexus injuries. Their characteristics have been scarcely reported in the literature. The priority of functional restoration is not clear. METHODS: In total, 52 children with surgically treated traumatic brachial plexus injuries, excluding Erb's palsy, were reviewed after a minimum follow-up of 2 years. All children except nine were males, with an average age at surgery of 8 years. Forty-five children had exclusive supraclavicular plexus injuries. Twenty-one of them (46%) had two or more root avulsions. Seven children (13.5%) had infraclavicular plexus injuries. Time from trauma to surgery varied from 1 to 15 months (mean = 4.7 months). Extraplexal neurotization was the most common surgical technique used. RESULTS: Shoulder abduction and external rotation were restored to an average of 83 and 26 degrees, respectively. Elbow flexion and extension were restored to grade ≥3 in 96 and 91.5% of cases, respectively. Finger flexion and extension were restored to grade ≥4 in 29 and 32% of cases, respectively. Wrist flexion and extension were restored to grade ≥4 in 21 and 27% of cases, respectively. Results of neurotization were superior to those of neurolysis and nerve grafting. Among the 24 children with insensate hands, 20 (83.3%) recovered S3 sensation, 3 recovered S2, and 1 recovered S1. No case complained of neuropathic pain. Functional recovery correlated negatively but insignificantly with the age at surgery and time from injury to surgery. CONCLUSION: Brachial plexus injuries in children are associated with a high incidence root avulsions and no pain. Neurotization is frequently required and the outcome is not significantly affected by the delay in surgery. In total plexus injuries, some useful hand function can be restored, and management should follow that of obstetric palsy and be focused on innervating the medial cord.

BACKGROUND: The long-term results of soft tissue rebalancing procedures of the shoulder in obstetric brachial plexus palsy have been scarcely reported. The effect of this procedure on the evolution of secondary bone changes has been a subject of controversy. METHODS: Twenty-six children are included in this study. All initially had postganglionic C5-6 or C5-7 (Narakas types I and II) obstetric brachial plexus palsy, which spontaneously recovered. Children included are those who had persistent external rotation weakness with or without internal rotation contracture, nondysplastic glenohumeral joint, and functioning teres major. All had anterior shoulder release and teres major to infraspinatus transfer to correct internal rotation deformity and/or increase active shoulder external rotation. Patients were 18 males and 8 females. The right upper limb was affected in 16 patients, and the left in 10. Surgery was performed at an average age of 3.01 years (range, 1-10 years). Follow-up averaged 8.2 years (range, 5-16 years). Eight cases (30%) were followed up for 10 years or greater. Age at final follow-up averaged 10.5 years (range, 6-17.8 years). RESULTS: The results showed to be significant: 67 degrees (63%), 71.3 degrees (412%), and -32 degrees (-35%), respectively. There was no single recurrence of internal rotation deformity. Global Mallet score averaged 20 ± 2.7. Global abduction and external rotation averaged 3.5 ± 0.8 and 4 ± 0.3, respectively. Shoulder abduction range included an average of 45 degrees glenohumeral and 65 degrees scapulothoracic motion. Postoperative internal rotation in adduction was limited to 55.96 ± 25.65 degrees and was significantly lower that the preoperative value. Radiological measurements showed no significant differences between the operated and normal sides. CONCLUSIONS: We conclude that the long-term results after soft tissue rebalancing, combined with open reduction when required, demonstrated significant improvement of abduction and external rotation and significant loss of internal rotation. The difference in glenoid version and humeral head subluxation continued to be insignificant compared with the normal side.

OBJECTIVE: To assess the diagnostic accuracy of direct wrist MR arthrography (MRA) compared to conventional MRI in diagnosis of different pathologic entities causing chronic wrist pain. MATERIALS AND METHODS: 37 consecutive patients 22 males and 15 females, with age range from 16 to 49 years "mean age 28 years" complaining of unexplained chronic wrist pain were prospectively examined by using MRI and MRA with arthroscopic correlation in 25 of them. Findings were divided into 5 main groups of lesions including triangular fibrocartilage complex (TFCC) lesions, ligamentous injuries, osseous lesions, tendon pathology and ganglion. RESULTS: MRA picked up more ligamentous injuries and triangular fibrocartilage complex (TFCC) lesions that couldn`t be detected on MRI study while both were equal in detection of other types of lesions. TFCC lesions were the most common pathologic findings in both MRI and MRA. Arthroscopic correlation in 25 suspected TFCC lesions (clinically, radiologically or both) revealed that the sensitivity / specificity / accuracy of MRI and MRA were 87.5% / 100% / 96% and 100% / 100% / 100% respectively for central lesions while were 71.4% / 81.3% / 76% and 100% / 90.9% / 96% respectively For peripheral lesions. Extra-capsular lesions, like tenosynovitis and fracture hook of hamate couldn`t be confirmed arthroscopically. CONCLUSION: MRA can replace both MRI and diagnostic arthroscopy in detecting causes of chronic wrist pain.
RESUMO
PURPOSE: The aim of this study is to evaluate the clinical outcome of single-incision flexor hallucis longus tendon transfer in chronic Achilles tendon rupture. METHODS: A prospective study of a series of cases of chronic Achilles tendon rupture that were treated with single-incision flexor hallucis longus tendon transfer, from April 2015 to December 2016. The study included 21 patients (15 men and 6 women), with mean age 40.3 ± 17.5 years. The average follow-up time was 15 (12-24) months. Flexor hallucis longus transfer was fixed with a titanium interference screw in an intraosseous calcaneal tunnel. RESULTS: The average operative time was 52.9 ± 8.7 minutes. The AOFAS-hindfoot score was significantly improved from the mean pre-operative value of 57.4 ± 10.3 to mean value of 95.3 ± 4.4 (p value < 0.001). There was no effect on the big toe function. The complication recorded was one superficial wound infection which resolved by dressing and appropriate antibiotic coverage. All patients were satisfied with the results of surgery. CONCLUSIONS: Single-incision flexor hallucis longus transfer for chronic Achilles tendon ruptures is a simple method with minimal morbidity and complications. The technique resulted in great patients' satisfaction as well as excellent functional and clinical outcomes.

BACKGROUND: There has been controversy regarding the pathogenesis and treatment of TFCC tear. Different surgical techniques for the treatment of TFCC are prescribed. The purpose of this study was to evaluate the short-term outcomes of arthroscopic outside-in repair of the ulnar side TFCC tear with vertical mattress suture. METHODS: In this study, arthroscopic outside-in repair of the ulnar side TFCC tear was done. 37 patients with TFCC tear with failure of conservative treatment for a minimum of 6 months had surgery. Outcomes were assessed using modified Mayo wrist score (MMWS), the Disability of the Arm, Shoulder, and Hand (DASH), visual analog scale (VAS) for pain and satisfaction criteria, and patient-related wrist evaluation score (PRWE), in addition to the range of motion and grip strength. RESULTS: After arthroscopic surgery, overall satisfaction was extremely positive, and out of the 37 patients, 91.9% of the patients are satisfied. The mean score for pain improved from 7.6 to 2.9 points. The mean MMWS was improved from 62.1 to 91.2 points. DASH score also improved from 29.9 to 10.2 points and PRWE improved from 60 to 33 points. The ROM was improved from 85.8% to 92% of the normal side. The grip strength of the affected side improved from 82.5% to 89% of the normal side. All improvements are statistically significant (P < 0.05). CONCLUSION: Arthroscopic outside-in repair of ulnar side TFCC tear with mattress suture is a reproducible method with a marked improvement in function within a short period.
RESUMO
BACKGROUND: In late obstetric brachial plexus palsy (OBPP), restoration of elbow and hand functions is a difficult challenge. The use of free functioning muscle transplantation in late OBPP was very scarcely reported. In this study, we present our experience on the use of free functioning gracilis transfer for restoration of elbow and hand functions in late cases of OBPP. PATIENTS AND METHODS: Eighteen patients with late OBPP underwent free gracilis transfer for reconstruction of elbow and/or hand functions. The procedure was indicated when there was no evidence of reinnervation on EMG and in the absence of local donors. Average age at surgery was 102.5 months. Patients were evaluated using the British Medical Research Council (MRC) grading system and the Toronto Active Movement Scale. Hand function was evaluated by the Raimondi scoring system. RESULTS: The average follow-up was 65.8 ± 41.7 months. Contraction of the transferred gracilis started at an average of 4.5 ± 1.03 months. Average range of elbow flexion significantly improved from 30 ± 55.7 to 104 ± 31.6 degrees (P <0.001). Elbow flexion power significantly increased with an average of 3.8 grades (P = 0.000147). Passive elbow range of motion significantly decreased from an average of 147 to 117 degrees (P = 0.003). Active finger flexion significantly improved from 5 ± 8.3 to 63 ± 39.9 degrees (P < 0.001). Finger flexion power significantly increased with an average 2.7 grades (P < 0.001). Only 17% achieved useful hand (grade 3) on Raimondi hand score. Triceps reconstruction resulted in an average of M4 power and 45 degrees elbow extension. CONCLUSION: Free gracilis transfer may be a useful option for reconstruction of elbow and/or hand functions in late OBPP.

Palmer devised a classification system to guide treatment of triangular fibrocartilage complex tears in 1989. The main division is between traumatic Type I and atraumatic Type II tears. The wrist arthroscopy makes diagnosis and treatment of ulnar impaction syndrome possible in a less invasive way. Arthroscopy is the most valuable tool for diagnosis and treatment of acute scapholunate and lunotriquetral dissociation. Arthroscopic grading of Kienböck's disease better describes articular damage compared with plain radiographs and can help surgical treatment. The wrist arthroscopy generally makes it possible to make the diagnosis of the chondral lesion before they are visible by the usual imaging.
RESUMO
The published experience of obstetrical brachial plexus palsy (OBPP) cases with poor recovery and late neurosurgical intervention are sparse. This study included 19 cases who presented after the age of 1 year with poor recovery of elbow and/or hand function and electrophysiological evidence of reinnervation. Age at surgery averaged 41 months, and the follow-up averaged 50 months. Distal neurotization was performed for restoration of elbow flexion in 11 cases, elbow extension in 3 cases, and finger flexion and/or sensibility in 5 cases. Active elbow flexion increased from an average of 2.7 to 91.8 degrees with an average gain of 89 degrees. Active elbow extension increased from an average of 10 to 56.7 degrees with an average gain of 46.7 degrees. Although, three out of five cases (60%) showed satisfactory recovery of finger flexion, all cases scored<2 using Raimondi score. Four cases gained protective sensation and one case gained discriminative sensation. The results of neurotization in late OBPP are variable. The best and most consistent results are obtained by necrotizing the biceps by the intercostal nerves or, in selected cases, by the flexor carpi ulnaris fascicle of the ulnar nerve. Delayed neurotization is the only way to recover sensory function in the hand.

Very limited literature described the use of the free anterolateral thigh (ALT) among other flaps for pediatric lower limb reconstruction. The aim of this study is to present our experience using the free ALT flap for reconstruction of soft tissue defects over the dorsum of the foot and ankle in children. The study included 42 children aged 2.5-13 years with a mean of 6.18 years. Three children had crush injuries while the rest were victims of run over car accidents. All of the flaps were vascularized by at least two perforators; 88.23% were musculocutaneous and 11.77 were septocutaneous perforators. All flaps were raised in a subfascial plane. Initial thinning was performed in five flaps and 35% required subsequent debulking. Mean Flap surface area was 117.11 cm(2). The recipient arteries were the anterior tibial artery in 38 cases and posterior tibial artery in four cases. Venous anastomosis was performed to one vena commitant and in nine cases the long saphenous vein was additionally used. Mean ischemia time of the flap was 2 hours while total operative time averaged 6.3 hours. About 41% of donor sites were closed primarily while 59% required skin grafting. Primary flap survival rate was 92.8% (39/42 cases). Three flaps showed venous congestion. After venous reanastomosis, two flaps showed partial loss and one flap was lost completely. Post-operative hospital stay averaged 7.5 days. The free ALT flap could be as safe, reliable, and aesthetically appealing option for foot/ankle resurfacing in children after traumatic soft tissue loss.

Between 1999 and 2005, seven patients had resection of tumors around the knee joint that involved half of the articular surface of the femoral or tibial side. Average age of the patients was 28 years (range, 14-40). Tumor pathology was giant cell tumor in four patients, osteoblastoma in two, and benign fibrous histocytoma in one patient. Two patients had recurrent tumors. The tumor was located in the distal femur in five patients and in the proximal tibia in the remaining two. The ipsilateral patella pedicled on the infrapatellar fat pad was used to substitute the resected articular surface and a vascularized fibula osteoseptocutaneous flap was used to reconstruct the metaphyseal defect. Average follow-up period was 6.5 years (range, 3.5-10 years). All flaps survived. Average time to bone union was 3.5 months (range, 3-4 months), and average time to full weight-bearing was 5 months (range, 4-6 months). No radiological signs of avascular necrosis of the patella were observed in any patient. Two patients required secondary procedures for correction of instability. One patient had local recurrence. At final follow-up, the median range of knee motion was from 10° to 100°. The average Knee Society Score (KSS) was 76 points (range; 50-85 points), and the average KSS functional score was 76.6 points (range, 70-90 points). In conclusion, the procedure is a reliable option for after resection of tumors that involve half the articular surface of the femur or the tibia.

From 2000 to 2006, 35 infants with total obstetric brachial plexus palsy underwent brachial plexus exploration and reconstruction. The mean age at surgery was 10.8 months (range 3-60 months), and the median age was 8 months. All infants were followed for at least 2.5 years (range 2.5-7.3 years) with an average follow-up of 4.2 years. Assessment was performed using the Toronto Active Movement scale. Surgical procedures included neurolysis, neuroma excision and interposition nerve grafting and neurotization, using spinal accessory nerve, intercostals and contralateral C7 root. Satisfactory recovery was obtained in 37.1% of cases for shoulder abduction; 54.3% for shoulder external rotation; 75.1% for elbow flexion; 77.1% for elbow extension; 61.1% for finger flexion, 31.4% for wrist extension and 45.8% for fingers extension. Using the Raimondi score, 18 cases (53%) achieved a score of three or more (functional hand). The mean Raimondi score significantly improved postoperatively as compared to the preoperative mean: 2.73 versus 1, and showed negative significant correlation with age at surgery. In total, obstetrical brachial plexus palsy, early intervention is recommended. Intercostal neurotization is preferred for restoration of elbow flexion. Tendon transfer may be required to improve external rotation in selected cases. Apparently, intact C8 and T1 roots should be left alone if the patient has partial hand recovery, no Horner syndrome, and was operated early (3- or 4-months old). Apparently, intact nonfunctioning lower roots with no response to electrical stimulation, especially in the presence of Horner syndrome, should be neurotized with the best available intraplexal donor.

A typical case of Dupuytren's contracture confined to the interphalangeal joints of the right little finger, occurred in a 79-year-old man. No past history of risk factors or family history of Dupuytren's disease could be detected. Excisions of the abnormal cords lead to good clinical outcome.
