Functional outcome after the nonsurgical treatment for adolescent spasmodic valgus foot.

BACKGROUND: Adolescent spasmodic valgus foot is usually associated with resistant pain and deformity. It shows controversy regarding its incidence, etiology, and treatment. Our study aimed to evaluate the functional outcome after the nonsurgical treatment for such condition. METHODS: This study included 50 planovalgus feet secondary to peroneal or peroneo-extensor spasm in 33 adolescents with a mean age of 14 ± 2.8 years. The procedure included foot manipulation under general anesthesia, sinus tarsi injection with corticosteroids, and a walking cast in the neutral position. Patients were evaluated functionally (using the American Orthopedic Foot and Ankle Society (AOFAS)) and radiologically before the procedure, after cast removal, and 3, 9, and 18 months later with special attention given for recurrence during the follow-up period with a mean duration of 22.5 ± 3.5 months. RESULTS: Once general anesthesia had been conducted, the deformity was corrected without any manipulation, and full passive inversion could be easily obtained in 26 feet, the deformity was corrected only after manipulation, and full passive inversion had been obtained in 14 feet, while 10 feet remained stiff even after manipulation. The mean AOFAS score was significantly improved ( p < 0.001) from 40.9 ± 3.5 at presentation to 73.56 ± 5.2 at the last follow-up in which 12 feet was painless and freely mobile and 24 feet had partial relapse, while 14 feet had complete relapse. CONCLUSION: The nonsurgical treatment for adolescent spasmodic valgus foot could be a simple and effective treatment. Apart from limited complete recurrence, the overall functional outcome was satisfactory. Level of evidence: type IV case series.

Mid-Sole Release of the Plantar Fascia Combined With Percutaneous Drilling of the Calcaneus for Treatment of Resistant Heel Pain.

BACKGROUND: Heel pain with or without calcaneal spur is a challenging problem. Once conservative measures have failed, surgery may be indicated; there has been debate about the best surgical procedure. Two standard operative procedures have been either releasing the plantar fascia or removing the spur with drilling of the calcaneus. In this study, we evaluated the results of percutaneous drilling of the calcaneus combined with mid-sole release of the plantar fascia for treatment of resistant heel pain. METHODS: This study included 20 cases with resistant heel pain after failure of conservative measures for 6 months. Clinical, radiological evaluation and scoring patients' conditions according to the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot scale was done preoperatively and postoperatively. Percutaneous drilling of the calcaneus combined with mid-sole release of the plantar fascia was done in all cases, and the functional results were evaluated through the follow-up period that extended from 9 to 16 months with a mean duration of 12 ± 2.3 months. RESULTS: There was statistically significant improvement in the mean AOFAS Ankle-Hindfoot scale score from 50.8 ± 7.5 preoperatively to 91.6 ± 7 postoperatively at the last follow-up. There were no surgery-related complications, and the mean time for full recovery was 8 ± 3.7 weeks with no recurrence of pain by the last follow-up. CONCLUSIONS: The results were very satisfactory with using this minimally invasive and simple technique for treatment for resistant heel pain. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Transfixing Kirshner wires for fixation of intertrochanteric valgus osteotomies in management of pediatric coxa vara.

BACKGROUND: Coxa vara is a radiological term describing a decrease in the neck-shaft angle to 120° or less. Coxa vara is associated with pathomechanical changes that can manifest clinically. If left untreated, coxa vara can affect the normal development of the pediatric hip. Valgus osteotomy is the standard surgical treatment for coxa vara, but there is no consensus regarding the optimal osteotomy technique and fixation method. The work reported here aimed to highlight transfixing wires as a fixation method for valgus osteotomy applied as treatment for various types of pediatric coxa vara. MATERIALS AND METHODS: This study included 16 cases of pediatric coxa vara with different etiologies in 9 patients with a mean age of 39.9 ± 15.2 months. Radiological and clinical evaluations and scoring of the condition of each patient according to the Iowa Hip Score were performed pre- and postoperatively. Transfixing wires and a protective spica were used for the fixation of a V-shaped, laterally based, closing-wedge valgus osteotomy in all cases. The postoperative follow-up period ranged from 14 to 102 months, with a mean duration of 33.3 ± 27.7 months. RESULTS: The mean Hilgenreiner epiphyseal angle (HEA) was corrected from 81.7 ± 2.2° to 24.3 ± 3.5° and the mean femoral neck-shaft angle (FNSA) was improved from 86.9 ± 4.2° to 138.6 ± 3.5°. No recurrence of the deformity was observed during the follow-up periods considered here. The osteotomy site united after an average of 11.7 ± 2.2 weeks with no secondary displacement, and in cases of developmental coxa vara there was progressive ossification of the neck defect with no surgery-related complications. Clinical results were markedly improved by the osteotomy, with a mean postoperative Iowa Hip Score at last follow-up of 95.06 ± 2.6, compared to a mean preoperative score of 57.4 ± 3.6. CONCLUSIONS: Transfixing wires protected in a hip spica cast represent a simple, easy, and reliable fixation method for valgus osteotomies performed to correct pediatic coxa vara. It assures stable fixation and rapid healing of the osteotomy without loss of the achieved correction, it completely avoids the femoral neck affording marked protection to the growth plate.

Triceps-sparing approach for open reduction and internal fixation of neglected displaced supracondylar and distal humeral fractures in children.

BACKGROUND: Supracondylar humeral fractures are one of the most common skeletal injuries in children. In cases of displacement and instability, the standard procedure is early closed reduction and percutaneous Kirschner wire fixation. However, between 10 and 20 % of patients present late. According to the literature, patients with neglected fractures are those patients who presented for treatment after 14 days of injury. The delay is either due to lack of medical facilities or social and financial constraints. The neglected cases are often closed injuries with no vascular compromise. However, the elbow may still be tense and swollen with abrasions or crusts. In neglected cases, especially after early appearance of callus, there is no place for closed reduction and percutaneous pinning. Traditionally, distal humeral fractures have been managed with surgical approaches that disrupt the extensor mechanism with less satisfactory functional outcome due to triceps weakness and elbow stiffness. The aim of this study is to evaluate the outcome of delayed open reduction using the triceps-sparing approach and Kirschner wire fixation for treatment of neglected, displaced supracondylar and distal humeral fractures in children. MATERIALS AND METHODS: This prospective study included 15 children who had neglected displaced supracondylar and distal humeral fractures. All patients were completely evaluated clinically and radiologically before intervention, after surgery and during the follow-up. The follow-up period ranged from 8 to 49 months, with a mean period of 17 months. Functional outcome was evaluated according to the Mayo Elbow Performance Index (MEPI) and Mark functional criteria. RESULTS: All fractures united in a mean duration of 7.2 weeks (range 5-10 weeks) with no secondary displacement or mal-union. Excellent results were found at the last follow-up in 13 of the 15 patients studied (86.66 %), while good results were found in two patients (13.33 %) according to the MEPI scale. According to the Mark functional criteria, there was one patient with a fair result (6.66 %). CONCLUSION: The results were very satisfactory if compared with traditional operative techniques, with many advantages including anatomical reduction and fixation of the fractures, avoidance of ulnar nerve injury, preservation of the extensor mechanism, decrease in incidence of myositis ossificans around the elbow and decrease in post-operative stiffness.

A simple surgical technique for treatment of Freiberg's disease.

BACKGROUND: Of all the osteochondrosis, Freiberg's disease is reported to be the fourth most common, exceeded by Köhler's disease, Panner's disease, and Sever's disease. This disease usually occurs in the 2nd metatarsal head and relatively in the 3rd and 4th metatarsal heads. OBJECTIVE: The purpose of this study was to evaluate the outcome of debridement, synovectomy, dorsal closing wedge osteotomy and pin fixation for Freiberg's disease treatment. METHODS: Ten female patients, mean age 18.3 years; (ranged 14-24 years) were treated by the above mentioned technique. The main presenting symptom was pain on walking or sport; affected their daily life and activities and was not improved by non-surgical treatment. The second metatarsal head was affected in all patients. Halve of patients had a history of trauma. According to Smillie's classification, four patients were type V and six patients were type IV. Mean follow-up period was 19.2 months (range 6-36 months). RESULTS: Were assessed by the Lesser Metatarsophalangeal-Interphalangeal (LMPI)Scale by Kitaoka et al. At the final follow up, scoring was changed from (44-76) with an average 57 to (66-100) with an average 80. There was no case of infection, avascular necrosis, arthritis or pseudoarthrosis. CONCLUSION: We founded that dorsiflexion osteotomy of the metatarsal head is presented as a logical procedure that is simple, reliable, not destructive, and capable of good results regardless of the stage of the disease.
