Quantitative Evaluation of Palatal Lengthening After Cleft Palate Repair When a Buccal Flap Is Routinely Combined With Furlow's Z-Plasty.

INTRODUCTION: The use of a buccinator myomucosal flap in combination with Furlow's Z-plasty during primary and secondary palatal repairs has been proposed by many authors to overcome some of the limitations of Furlow's technique. However, there have been no studies that quantitatively measured the effective palatal lengthening when the buccal flap is added. PATIENTS AND METHODS: The buccal flap is routinely used during primary palate repair in order to fill the gap between the hard palate and reoriented palatal muscle sling. The soft palatal length was measured in the midline from the posterior edge of the hard palate to the base of the uvula. All patients were measured before starting the surgery and just after palatal closure in the standard position for cleft palate repair. RESULTS: Seventy-three patients with cleft palate who were candidates for primary repair were included. The mean age at the time of operation was 11.4 ± 3.5 months. The mean preoperative palatal length was 21.36 ± 3.529 mm, whereas the mean postoperative palatal length was 29.64 ± 4.171) mm. The mean palatal length change was 8.29 ± 2.514 mm (P < 0.000). CONCLUSIONS: The Combined use of a buccinator myomucosal flap with modified Furlow's Z-plasty in primary cleft palate repair has proven effective for palatal lengthening and achieved tensionless closure without the need for relaxing incision. It also provided a pliable soft tissue attachment of the palatal muscles to the hard palate allowing for better muscle function and mobility.

The Added Diagnostic Value of the Bright Rim Sign to Conventional MRI Assessment of Anterior Talofibular Ligament Disruption.

RATIONALE AND OBJECTIVES: The bright rim sign (BRS) was used as a reliable indicator of anterior talofibular ligament (ATFL) disruption beside other well-known diagnostic criteria. Although this sign can improve accuracy of conventional magnetic resonance imaging (MRI) in diagnosis of ATFL disruption, it was not adequately discussed in the literature. This study aimed to confirm the added diagnostic value of BRS to conventional MRI assessment of ATFL disruption. MATERIALS AND METHODS: A prospective study included 62 patients (47 males and 15 females; mean age, 36.9 ± 12.1 years; range, 17-52 years) with clinically suspected ATFL disruption. All patients underwent MRI and arthroscopy of ankle. MRI images were evaluated for the presence of ligament disruption sign (LDS) and BRS. The patients were classified into 3 groups: group 1 included patients with acute lateral ankle ligament sprain; group 2 included patients with chronic ankle instability; and group 3 included patients with recurring ankle sprain. The diagnostic value of the BRS was evaluated using arthroscopy as reference standard. RESULTS: The diagnostic value of both signs together increased overall sensitivity in detecting ATFL disruption to 86.7% compared to 60% when considering LDS alone (p < 0.0001). In group 1 and 3, the sensitivity increased when both signs were considered together compared to LDS alone (p = 0.004 and 0.025, respectively). In group 2, there was a trend toward significance in sensitivity when both signs were considered compared to LDS alone (p = 0.08). CONCLUSION: BRS is a very helpful diagnostic sign in assessment of ATFL disruption when considered conjointly with the LDS.

Diagnostic accuracy of ultrasonography in the assessment of anterior knee pain.

BACKGROUND: Anterior knee pain (AKP) is a problematic complaint, considered to be the most frequent cause of orthopedic consultancy for knee problems. This study aimed to highlight diagnostic accuracy of ultrasonography as a fast imaging technique in assessment of patients with AKP. METHODS AND RESULTS: A prospective study was conducted on 143 patients with clinically confirmed AKP. All patients underwent ultrasonography and MRI examinations of the knee. The diagnostic accuracy of ultrasonography compared to MRI for evaluating different findings of possible causes of AKP were analyzed using receiver operating characteristic (ROC) curve and judged by area under curve (AUC). A total of 155 knees were included in the study; 26 knees showed no abnormalities, 19 knees showed positive MRI only, and 110 knees showed positive ultrasonography and MRI. Ultrasonography and MRI reported 11 different findings of possible causes of AKP or related to it. Joint effusion was the most common finding (38%) followed by trochlear cartilage defect (20.6%) and superficial infrapatellar subcutaneous edema (20%). The overall accuracy of ultrasonography was 85.3% sensitivity and 100% specificity. The ultrasonography provided the highest sensitivity (100%) in detecting bipartite patella, followed by 91.5% for joint effusion, and 87.5% for quadriceps tendinopathy. The ROC curve analysis of overall accuracy of ultrasonography showed an AUC of 0.93. The overall Kappa agreement between ultrasonography and MRI was good (k = 0.66). CONCLUSION: Ultrasonography can be used to make a swift screening and assessment of painful anterior knee and as an alternative to MRI when it is unavailable or contraindicated.

Short Segment versus Long Segment Pedicle Screws Fixation in Management of Thoracolumbar Burst Fractures: Meta-Analysis.

Posterior pedicle screw fixation has become a popular method for treating thoracolumbar burst fractures. However, it remains unclear whether additional fixation of more segments could improve clinical and radiological outcomes. This meta-analysis was performed to evaluate the effectiveness of fixation levels with pedicle screw fixation for thoracolumbar burst fractures. MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Springer, and Google Scholar were searched for relevant randomized and quasirandomized controlled trials that compared the clinical and radiological efficacy of short versus long segment for thoracolumbar burst fractures managed by posterior pedicle screw fixation. Risk of bias in included studies was assessed using the Cochrane Risk of Bias tool. Based on predefined inclusion criteria, Nine eligible trials with a total of 365 patients were included in this meta-analysis. Results were expressed as risk difference for dichotomous outcomes and standard mean difference for continuous outcomes with 95% confidence interval. Baseline characteristics were similar between the short and long segment fixation groups. No significant difference was identified between the two groups regarding radiological outcome, functional outcome, neurologic improvement, and implant failure rate. The results of this meta-analysis suggested that extension of fixation was not necessary when thoracolumbar burst fracture was treated by posterior pedicle screw fixation. More randomized controlled trials with high quality are still needed in the future.

Efficacy of pulsed Nd:YAG laser in the treatment of patients with knee osteoarthritis: a randomized controlled trial.

The purpose of this study was to investigate the effects of pulsed Nd:YAG laser plus glucosamine/chondroitin sulfate (GCS) in patients with knee osteoarthritis (KOA) by examining changes in pain and knee function, as well as synovial thickness (ST) and femoral cartilage thickness (FCT). Sixty-seven male patients participated, with a mean (SD) age of 53.85 (4.39) years, weight of 84.01 (4.70) kg, height of 171.51 (3.96) cm, and BMI of 28.56 (1.22). Group 1 was treated with high-intensity laser therapy (HILT), GCS, and exercises (HILT + GCS + EX). Group 2 was treated with GCS plus exercises (GCS + EX), and group 3 received placebo laser plus exercises (PL + EX). The outcomes measured were pain level and functional disability using the visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), respectively. ST and FCT were measured by ultrasound examination. Statistical analyses were performed to compare differences between baseline and after 6 weeks of treatment and then after 3 months of follow-up. Statistical significance was set at p < 0.05. VAS and WOMAC were significantly decreased in all groups after 6 weeks, with nonsignificant differences between 6 weeks and 3 months of follow-up. ST was significantly decreased in the HILT + GCS + EX group posttreatment, with nonsignificant decreases in the GCS + EX and PL + EX groups, as well as nonsignificant differences to FCT in all groups. Overall, pulsed Nd:YAG laser combined with GCS and exercises was more effective than GCS + EX and exercises alone in the treatment of KOA patients.

Endometrial Injury May Increase the Pregnancy Rate in Patients Undergoing Intrauterine Insemination: An Interventional Randomized Clinical Trial.

OBJECTIVE: This study aimed to investigate the effect of endometrial injury using Pipelle catheter in the follicular phase (cycle day 5, 6, or 7) of the stimulation cycle on pregnancy rates in patients undergoing intrauterine insemination. METHODS: This prospective randomized controlled study was carried out in the Assisted Reproductive Technology Unit of Ain Shams University Maternity Hospital, Cairo, Egypt, from July 1, 2013 to August 31, 2015. Three hundred sixty women, 20 to 35 years of age, with patent fallopian tubes, mild male factor infertility, or unexplained infertility were recruited. Participants were allocated randomly into 2 groups: experimental arm and control arm. Women in the experimental arm underwent endometrial biopsy using a Pipelle catheter on day 5, 6, or 7 of the stimulation cycle combined with intrauterine insemination. Women in the control group underwent intrauterine insemination with no endometrial biopsy done. The primary outcomes were the clinical and chemical pregnancy rates. RESULTS: Data of 344 participants were statistically analyzed. The chemical pregnancy rate was 23.66% in the experimental arm and 10.85% in the control arm (P = .002). The clinical pregnancy rate was 18.93% in the experimental arm and 7.42% in the control arm (P = .003). CONCLUSION: Endometrial injury using a Pipelle catheter in the stimulation cycle may improve pregnancy rates in women undergoing intrauterine insemination.

Multivessel spontaneous coronary artery dissection in an unlikely patient.

When approaching the symptom of acute onset chest pain in a previously healthy 26-year-old male, anchoring heuristic presents a challenge to healthcare workers. This diagnostic error is the healthcare professional's tendency to rely on a previous diagnosis, and, in situations where a set of symptoms might mask a rare and deadly condition, this error can prove fatal for the patient. One such condition, Spontaneous Coronary Artery Dissection (SCAD), is an uncommon and malefic presentation of coronary artery disease that can lead to myocardial infarction and sudden death. We present a case of SCAD in an otherwise healthy 26 year-old male who had been experiencing chest pain during and after sports activity. In the young, athletic male with SCAD, the danger of diagnostic error was a reality due to the broad symptomatology and the betraying demographics.

Efficacy of delayed decompression of lumbar disk herniation causing cauda equina syndrome.

Cauda equina syndrome (CES) is a rare but serious neurosurgical emergency that can have devastating long-lasting neurologic consequences. Compression of the cauda equina can result in paralysis of bowel and bladder function. Such compression has been considered the only absolute indication for surgery in cases of lumbar disk disease. Therefore, it is extremely important that physicians be aware of the condition so that a surgeon is consulted before neurological damage becomes permanent. This article reports the results of delayed surgical decompression in cases of lumbar disk herniation with CES. The study group comprised 14 patients (11 men and 3 women) with a mean age of 48 years (range, 36-57 years). Clinical presentation was chronic low back pain, sciatica, and impaired sphincter function. All patients had a fenestration at the affected level and site, and the disk fragments were excised and the disk space cleared. The surgeries were performed 1 to 3 months after onset of sphinctric disturbance. Postoperatively, all patients were relieved of back and/or leg pain and showed sensory improvement. Twelve patients regained full control of urination and defecation. Lower extremity strength improved in 9 patients. The classical presentation of CES is not obvious. Even if surgery is performed late due to delayed presentation, significant improvement in neurologic and bladder function can still be expected.

Posterior acetabular column and quadrilateral plate fractures: fixation with tension band principles.

Acetabular fractures can be classified into 5 simple and 5 associated fracture patterns. A significant amount of variation and complexity exists in these fractures patterns. Fractures of the posterior wall are the most common acetabular fractures. Comminution of the quadrilateral plate adds to fracture instability, and more rigid and stable internal fixation is mandatory. The goal of this study was to assess the results of reconstruction of comminuted posterior wall fractures of the acetabulum associated with quadrilateral plate fractures using the tension band technique. Twelve patients (9 men and 3 women) were included in the study. Mean patient age was 38.6 years (range, 24-47 years). Minimum follow-up was more than 2 years postoperatively. Reconstruction of the fracture included anatomic reduction of the fracture and fixation with a buttress plate for the posterior column and a prebent one-third tubular plate for the quadrilateral plate fracture. Clinical results were excellent in 58% of patients and good in 17% of patients. Radiologic results were excellent in 50% of patients and good in 17% of patients. Radiologically, based on the fracture gap postoperatively, 8 (66%) patients showed anatomic reduction, 2 (17%) showed good reduction, and 2 (17%) showed poor reduction. The study confirms that this method of reconstruction facilitates accurate and firm reduction of displaced posterior wall fractures of the acetabulum.

Geometrical dimensions and morphological study of the lumbar spinal canal in the normal Egyptian population.

Information regarding the precise dimensions of the lumbar vertebrae is essential for spinal surgery and instrumentation. When stenosis of the vertebral canal or the intervertebral foramen exists, the neural structures in them can be affected and cause symptoms such as low back or radicular pain. Accurate and comprehensive spinal canal measurements in the lumbar vertebrae are incomplete. The purpose of this study was to collect data on the dimensions of the lumbar spinal canal from computed tomography scans. Three hundred patients (162 men and 138 women) were studied. Computed tomography scans were obtained to determine the normal values of the midsagittal diameter, interpedicular distance, and lateral recess depth in the normal Egyptian population. The narrowest level was L3. The range of the midsagittal diameter was 11.07 to 26.07 mm at all levels. The range of the interpedicular distance was 17.00 to 43.41 mm at all levels. In all patients at all levels, mean lateral recess depth was 6.7 mm (range, 4-14 mm). The narrowest lateral recess depth was at L5. Few patients (3.3%) had a statistically stenotic midsagittal diameter measurement. The canal shape was not uniform along the 5 lumbar vertebrae; it ranged from being circular or rounded in the upper lumbar vertebrae to triangular in the midlumbar vertebrae to trefoil in the lower lumbar vertebrae, especially at L5. Trefoil canals existed mainly in the lower lumbar vertebrae at L5, followed by L4. Data from computed tomography scans combined with accurate measurements are the basis for anatomical studies, clinical research, and the development of implants suitable for a group of patients with measurements different from the population standard.

Intercalated bone PEG in the treatment of non-united scaphoid fractures.

INTRODUCTION: Untreated ununited scaphoid fractures will almost inevitably progress to radiographic and symptomatic osteoarthritis of the wrist. This may lead to subsequent morbidity and lifelong disability especially in young males in which the fracture scaphoid is more common. PATIENTS AND METHODS: Twenty-one patients presenting non-united fracture scaphoid were operated upon by using disto-proximal bone peg technique with average time between injury and operation as 11 months (6-18 months). All of them male with average age of 26 years (17-35 years). There were 17 patients with fracture waist (80.9%) and four patients with fracture proximal pole (19.1%). RESULTS: Anatomy of the wrist was restored and radiological healing confirmed in 17/21, partial healing in 3/21 and non-union in 3/21 patients. Eighteen patients (85.7%) were graded as satisfactory, 5 patients (23.8%) were graded as excellent, ten patients (47.6%) were graded as good, and three patients (14.3%) were graded as fair. The remaining three patients (14.3%) were graded as unsatisfactory. CONCLUSION: We conclude that the disto-proximal bone peg technique of taking the graft from the ipsilateral ulna without using any metal work for fixing scaphoid non-union fracture is a reliable, easy, and inexpensive alternative method. However, we would not recommend it for the non-union of the scaphoid proximal pole fracture. Also we find the time lag before operation is one of the most important factors to achieve union in non-united fractures of the scaphoid. LEVEL OF EVIDENCE: Therapeutic case series, level 1V.

Surgical management of chronic boutonniere deformity.

PURPOSE: Boutonniere deformity is caused by damage to the central slip of the extensor tendon hood with secondary palmer migration of the lateral bands. Accordingly, patients complain of disfigurement and impairment of function due to hyperextension of their DIP. The aim of this study is to evaluate the results of surgical treatment of chronic boutonniere deformity by using a modified technique. PATIENTS AND METHODS: Twelve patients with posttraumatic boutonniere deformity were available for follow up as a retrospective study. They were treated by release of the extensor expansion proximal to the distal insertion of the oblique retinacular ligaments with proximal recession of the extensor tendon and lifting the lateral bands dorsally onto the PIP joint after separation of the transverse retinacular ligaments from their insertion volarly. All patients had closed injury. The mean age was 32 years (range: 16-48 years). The average follow-up period was 33 months (range: 26-38 months). We included only cases with deformities that were totally correctable passively with or without joint osteoarthritic changes. RESULTS: Preoperatively the average PIP joint extension deficit was 60° and postoperatively the average is reduced to 7°, preoperative the average DIP motion was 10° of hyperextension, post-surgery the average DIP active flexion was 75°. The final outcomes were 58.3% excellent, 33.3% good, and 8.3% poor. DISCUSSION: This modified technique gave (91.6%) excellent and good results. The extensor tendon acted mainly on the PIP joint and allowing the DIP joint to flex freely. The procedure is simple and provides long-term good results. LEVEL OF EVIDENCE: Therapeutic case series, level 1V.

Management of valgus extra-articular calcaneus fracture malunions with a lateral opening wedge osteotomy.

A total of 34 cases of symptomatic valgus deformity of the hindfoot secondary to a malunited extra-articular calcaneal fracture were corrected with laterally based open wedge calcaneal osteotomy. The pre- and postoperative radiographic parameters were compared, and a postoperative clinical evaluation was performed using the American Orthopedic Foot and Ankle Society ankle and hindfoot scoring system. The mean follow-up period was 56.2 (range 24.1 to 97) months. The most significant radiographic changes were improvement in the talonavicular coverage angle (mean 17.3°) on the anteroposterior view. The mean postoperative American Orthopedic Foot and Ankle Society hindfoot and ankle score was 90, with 23 excellent, 8 good, and 3 poor results. Laterally based opening wedge osteotomy of the calcaneus is effective in the management of a valgus heel resulting from malunited extra-articular calcaneal fractures. Lateral decompression of the peroneal tendons and the sural nerve was achieved indirectly through opening wedge lateral calcaneal osteotomy that shifted the weight-bearing axis laterally.

Arthrodiatasis for management of knee osteoarthritis.

Osteoarthritic disease is the result of mechanical and biological events that destabilize the normal processes of degradation and synthesis of articular cartilage chondrocytes, extracellular matrix, and subchondral bone. Osteoarthritis of the knee can cause symptoms ranging from mild to disabling. Initial management of most patients should be nonoperative, but because of the progressive nature of the disease, many patients with osteoarthritis of the knee eventually benefit from operative treatment. Various procedures have been described for treatment of the osteoarthritic knee, ranging from arthroscopic lavage and debridement to total knee arthroplasty. The aim of this study was to evaluate the clinical results of distraction arthroplasty combined with arthroscopic lavage and drilling of cartilage defects for treatment of osteoarthritis of the knee. Nineteen patients (15 women and 4 men; age range, 39-65 years) were operated on. Pre- and postoperative findings were compared. A control group comprising 42 patients treated with only arthroscopic procedures was evaluated for comparison. Follow-up ranged from 3 to 5 years. Results were evaluated both clinically and radiologically postoperatively and throughout the follow-up period. Clinically, pain and walking capacity improved in most patients. Radiologically, joint space widening and improvement of the tibiofemoral angle was noted in nearly all patients.

Spinal shortening and monosegmental posterior spondylodesis in the management of dorsal and lumbar unstable injuries.

INTRODUCTION: Patients with spinal injuries have been treated in the past by laminectomy in an attempt to decompress the spinal cord. The results have shown insignificant improvement or even a worsening of neurologic function and decreased stability without effectively removing the anterior bone and disc fragments compressing the spinal cord. The primary indication for anterior decompression and grafting is narrowing of the spinal canal with neurologic deficits that cannot be resolved by any other approach. One must think of subsequent surgical intervention for increased stability and compressive posterior fusion with short-armed internal fixators. AIM: To analyze the results and efficacy of spinal shortening combined with interbody fusion technique for the management of dorsal and lumbar unstable injuries. MATERIALS AND METHODS: Twenty-three patients with traumatic fractures and or fracture-dislocation of dorsolumbar spine with neurologic deficit are presented. All had radiologic evidence of spinal cord or cauda equina compression, with either paraplegia or paraparesis. Patients underwent recapping laminoplasty in the thoracic or lumbar spine for decompression of spinal cord. The T-saw was used for division of the posterior elements. After decompression of the cord and removal of the extruded bone fragments and disc material, the excised laminae were replaced exactly in situ to their original anatomic position. Then application of a compression force via monosegmental transpedicular fixation was done, allowing vertebral end-plate compression and interbody fusion. RESULTS: Lateral Cobb angle (T(10)-L(2)) was reduced from 26 to 4 degrees after surgery. The shortened vertebral body united and no or minimal loss of correction was seen. The preoperative vertebral kyphosis averaged +17 degrees and was corrected to +7 degrees at follow-up with the sagittal index improving from 0.59 to 0.86. The segmental local kyphosis was reduced from +15 degrees to -3 degrees. Radiography demonstrated anatomically correct reconstruction in all patients, as well as solid fusion. CONCLUSION: This technique permits circumferential decompression of the spinal cord through a posterior approach and posterior interbody fusion.

Hip morphologic measurements in an Egyptian population.

The study of acetabular morphology has shown that there are geographic differences in the morphology and prevalence of acetabular dysplasia among different ethnic groups. However, few data exist on the shape of the acetabulum in various populations around the world. In this study, we examined samples of pelvic radiographs from Egyptian adults. Acetabular dysplasia in adults is characterized by a shallow and relatively vertical acetabulum.The aim of this study was to examine acetabular morphology to determine the prevalence of hip dysplasia in adult Egyptians. This included 244 adults, 134 men and 110 women between 18 and 60 years, who were used to measure center edge angle, acetabular Sharp angle, acetabular head index on anteroposterior radiographic views of the hip joints, and vertical center anterior margin angle on false profile views. The radiographs were taken of patients with no hip complaints at Tanta University Hospital.The results were statistically studied according to the age, height, and weight of patients. The prevalence of acetabular dysplasia was 2.25% for Egyptian men and 3.6% for women with respect to center edge angles, vertical center anterior margin angle, and acetabular head index.We concluded that gender variations in the morphology of the acetabulum and sex influences geometrical measurements of the acetabulum. Egyptian women were more dysplastic than men using the 4 parameters of hip measurements. There are also racial variations in hip morphology.

Evaluation of scarf osteotomy for management of hallux valgus deformity.

Hallux valgus is a complex progressive deformity affecting the forefoot. The main pathologic anatomy concerns the first metatarsophalangeal joint, including a varus or medial deviation of the first metatarsal and pronation deformity in the longitudinal axis. The goal of this study was to evaluate a series of consecutive patients over a 2-year period after a scarf osteotomy of the first metatarsal. A scarf osteotomy was performed on 31 consecutive patients with moderate to severe hallux valgus deformity (intermetatarsal angle, 13-22°; hallux valgus angle, 20-44°). Twenty-nine women and 2 men had an average age of 57 years (range, 21-71 years) at the time of surgery. Preoperative and postoperative evaluations included standing anteroposterior and lateral radiographs, American Orthopaedic Foot and Ankle Score (AOFAS) score, physical examination, and foot pressure analysis by weight-bearing ink prints. Patients were evaluated radiographically and clinically in the initial postoperative period (≤1 month), intermediate postoperative period (2-6 months), and final follow-up (12-36 months). Twenty-eight feet were available for analysis. Five of the 28 feet had concurrent surgeries on the lesser toes for hammer-toe correction or preoperative metatarsalgia. Paired Student t test on the 28 feet showed a statistically significant improvement (P<.0001) between pre- and postoperative intermetatarsal angle, hallux valgus angle, and AOFAS score. One foot had recurrence of the hallux valgus deformity. Paired analysis of variance of the 27 feet without recurrence showed a statistically significant improvement in the pre- and postoperative parameters (P<.0001). From this subset, the multiple-comparison Student-Newman-Keuis post hoc test showed a statistically significant (P<.0001) preservation of the correction in the intermediate follow-up period to final follow-up at an average 28 months.

Arthrodiatasis for the treatment of Perthes' disease.

It is hypothesized that the interruption of the blood supply is an important factor causing femoral head osteonecrosis in the early stages of Legg-Calvé-Perthes disease. Currently, treatment by containment is recommended to direct and guide remodeling of the softened femoral head as it evolves from fragmentation through ossification. The goal of this study was to show the results of arthrodiatasis to induce height recovery of the femoral head and to achieve true ambulatory nonweight-bearing containment. Forty-two patients younger than 8 years with a diagnosis of Perthes' disease were studied. Twenty-three patients (9 class B and 14 class C according to Herring's classification) were treated with an articulated distraction technique and 19 patients (11 class B and 8 class C) were treated conservatively as a control group. Arthrodiatasis or articulated distraction of the hip combines off-loading of muscles and body forces with distraction of the joint space by means of an external fixator that crosses the hip joint. Radiologically, 21 patients (91%) had satisfactory results and 2 (9%) had unsatisfactory results. Clinically, the results were good in 21 patients (92%), fair in 1 (4%), and poor in 1 (4%). In patients treated conservatively, 14 patients (72%) had satisfactory results and 5 (28%) had unsatisfactory results. Clinically, 71% had good results, 17% had fair, and 12% had poor. We conclude that hip joint containment by articulated arthrodiatasis (plus adductors and psoas minimal tenotomy surgery) is an effective method in the management of Perthes' disease in patients younger than 8 years, classified B and C, and associated with a highly reduced range of abduction. Restoration of clinical abnormalities and satisfactory radiological parameters are achieved in high percentages.
