UNASSIGNED: A 4-month-old male Shih Tzu dog (Case 1) and an 11-month-old female Devon Rex cat (Case 2) were referred to specialist veterinary hospitals for evaluation of right thoracic lameness and growth abnormality in the distal aspect of the forelimb.
UNASSIGNED: Non-weight-bearing lameness and decreased range of motion were noted in the affected limbs of both cases. Case 1 had a plantigrade stance, and a cleft separation between the first and second digits extending upwards to the distal third of the antebrachium. There was no pain on palpation, and the affected limb was shorter than the contralateral. Radiographic examination revealed cleft separation between metacarpal bones I and II, and carpal bone fusion (I, II, III), and the distal radius ended freely and was attached to the first metacarpal bone.Case 2 had a small cleft medial to metacarpal III. The limb was consistently held in abduction and had marked carpal varus. The limb had never been used for weight bearing. Radiographic examination showed agenesis of metacarpal bone II and separation of metacarpals I and III. The radius and ulna were separated and the radial head did not articulate normally at the elbow, leading to marked elbow incongruity.
UNASSIGNED: Ectrodactyly in both cases.
UNASSIGNED: Amputation of the radius followed by ulnocarpal arthrodesis were performed in both cases. Follow-up evaluations up to 1 year (Case 1) and 10 weeks (Case 2) after surgery indicated satisfactory arthrodesis fusion, owner satisfaction, and a good clinical outcome.
UNASSIGNED: Ectrodactyly is a rare congenital deformity of the forelimb with a heterogeneous character, requiring an individualised treatment plan. These are the first cases reported in the literature of ectrodactyly in small animals that were treated successfully with ulnocarpal arthrodesis. This case series therefore provides evidence in support of this treatment option for this heterogeneous congenital deformity.

OBJECTIVE: To assess the surgical accuracy of 3D virtually planned orthognathic surgery among patients with and without cleft.
METHODS: This retrospective cohort study included cleft and non-cleft patients with class III malocclusion who underwent bimaxillary surgery. CBCT scans were acquired before and immediately after surgery. 3D virtual surgical planning (VSP) was performed using CBCT and digitalized dentition data. All orthognathic surgeries were performed by the same surgeons using interocclusal splints. The primary outcome variable was surgical accuracy, defined as the difference between the planned and surgically achieved maxillary movements, quantified in six degrees of freedom. Analysis of covariance was used to test for intergroup differences in surgical accuracy after correcting for differences in the magnitude of planned surgical maxillary movements.
RESULTS: Twenty-eight cleft and 33 non-cleft patients were enrolled, with mean ages of 18.5 and 25.4 years, respectively (P=0.01). No significant gender difference was present between the groups (P=0.10). After adjustment for small differences in surgical movements, no significant differences in surgical accuracy were observed between cleft and non-cleft patients.
CONCLUSIONS: The present study demonstrates that high surgical accuracy in maxillary movements can be achieved in both cleft and non-cleft patients using VSP and interocclusal splints.
CONCLUSIONS: Orthognathic cases with cleft can be performed with 3D VSP to obtain a satisfactory surgical accuracy.

BACKGROUND: Thyroglossal duct cysts (TDC) are common congenital deformities. Most of them are cysts formed by the thyroglossal ducts that do not disappear and degenerate in the early embryonic stage. TDC exists alone and is rarely complicated by other congenital embryonic malformations. Only a few reports of TDC with branchial cleft cysts, thyroid cancer, thyroid hematoma, and epidermoid cysts have been reported. Therefore, we report a patient with TDC and parathyroid cyst (PC), a rare disease that has never been reported.
METHODS: A 47-year-old woman presented to clinic in April 2021 with a neck tumor which she had noticed 5 d earlier. We perfected the relevant examinations, such as ultrasound and computed tomography, and resected the tumor. After surgical treatment, the pathology revealed a cervical thyroglossal duct cyst and a left lobe parathyroid cyst. The patient was followed up for 1 year without significant recurrence.
CONCLUSIONS: We report a patient with a simultaneous TDC and a PC to explore the correlation between the two congenital anomalies.

In the past, open osteotomy was always performed through a dorsal approach in the surgical treatment of brachymetatarsia, which created scar formation on the dorsal skin, subsequently resulting in dissatisfaction with cosmetic results. In this study, we provided a plantar approach to avoid forming scars on the dorsal side. A retrospective review was conducted in nine patients (13 feet) with brachymetatarsia treated with an open osteotomy and gradual bone lengthening through a plantar approach. Visual analogue scale (VAS) was used to evaluate the satisfaction of foot appearance, and we designed a questionnaire called appearance index (AI) to assess the influence of foot appearance on quality of life after surgery. The complications were also recorded during the follow-up. The patients were followed up for 34.8 ± 23.7 months. All cases were healed with a time of 64.4 ± 7.1 days and a healing index of 44.1 ± 7.8 d/cm. Satisfaction VAS for foot appearance improved from a preoperative score of 1.7 ± 1.3 points to a postoperative score of 9.3 ± 0.5 points. The AI improved from a preoperative score of 9.2 ± 0.8 points to a postoperative score of 0.6 ± 0.7 points. Complications were observed in three feet (23.1%), but none was related to the plantar approach. In conclusion, the plantar approach for metatarsal osteotomy and pins fixation was a safe and efficient technique with a satisfactory cosmetic result for the patients. No complications related to the novel approach, such as neurovascular injury, were reported.

Nine individual Alouatta caraya and Sapajus cay displaying facial malformations were observed across three sites in Paraguay. Six had cleft lip (with or without cleft palate), and three had malformations of the lower lip. This is the first record of cleft lip and/or palate in the genus Alouatta.

BACKGROUND: Bilateral congenital absence of femur is a rare congenital anomaly.
METHODS: We report a 2-year-old Indonesian female child, the third of the birth of diabetic mother. There is no congenital abnormality among her siblings. She has a normal mentality and normal upper limbs. She was brought to us with a complaint of the short lower limb. Examination revealed short lower limb with an absence of thigh, a full range of motion of the hip and ankle and left club foot. A detailed history was obtained and she was radiologically examined. The X-ray of the pelvis and lower limb shows shallow of the acetabulum, absence of bilateral femur, and uncommon form of tibia fibula. She was diagnosed with bilateral congenital absence of femur.
CONCLUSIONS: We report this case because it does not meet the existing classification criteria for congenital femur deficiency. Proper evaluation and management of this case can help the patient and the parents to accept her condition and be able to live a good social and economically productive life.

OBJECTIVE: Previous ultrasound studies of clubfeet have mainly focused on the first year of life. The purpose of this study was to improve the evaluation of the talo-navicular and calcaneo-cuboid joints by adding new variables, evaluating the repeatability of ultrasound measurements for normal feet and clubfeet and establishing values for normal feet up to four years of age.
METHODS: A control group of 105 children divided into ten age groups, and 71 clubfeet in 46 children were examined. Four new variables were introduced: medial malleolus-Talar head-Navicular distance, medial tangent of the talus to the medial border of the navicular distance, the angle between the longitudinal axis of the talus and a line from the centre of the talar head to the medial corner of the navicular, the angle between the lateral borders of the calcaneus and the cuboid. The mobility in the talo-navicular and the calcaneo-cuboid joints was assessed by comparing measurements with the foot in adduction and abduction.
RESULTS: The variables could be assessed with fair to very good intra- and inter-observer repeatability (intraclass correlation coefficient > 0.8 and ≥ 0.6, respectively), with a few exceptions. There was less movement in talo-navicular and calcaneo-cuboid joints in clubfeet than in controls.
CONCLUSIONS: Morphology of normal feet and clubfeet, as well as mobility in the talo-navicular and calcaneo-cuboid joints, can be assessed by ultrasound with a fair to very good reliability from birth to the age of four years.
METHODS: III.

Objective: Brachymetatarsia is defined as the pathological shortening of a metatarsal bone, which can cause cosmetic problems and pain in the forefoot. The main surgical treatment options are: extension osteotomy, interposition of a bone graft, and callus distraction. Usually, a bone graft from the iliac crest is used for the interposition osteotomy. The operative technique of graft extraction from the fibula has not been described in the literature yet. Methods: Eight feet with brachymetatarsia in 5 patients were evaluated retrospectively. The minimum follow-up period was 2 years. Via a dorsal V/Y skin incision, a central osteotomy on the metatarsal bone was done. A graft was obtained from the anterior fibula. The graft was inserted and fixed by a locking plate. Additional soft tissue procedures were done. Results: We had bony consolidation in all cases. The mean extension was 9.01 mm (5.49 to 12.54 mm). This corresponded to a mean 20.3% extension of the entire metatarsal. High patient satisfaction as well as high satisfaction regarding the cosmetic results were achieved. There were no postoperative complications. The range of motion of the metatarsal-phalangeal joint IV was 20% less preoperative in terms of plantar flexion. Standing up on tiptoes was possible in all patients postoperatively. One patient reported mild symptoms after sports activities. Conclusions: Because of its anatomy the graft adapts to the metatarsal IV bone. As our study showed, harvesting from the distal fibula causes no functional restriction. In terms of wound and bone healing as well as pain symptoms, this method should be considered as an alternative to the standard iliac graft.

OBJECTIVE: Restoration of physiological alignment of the distal tibia and thereby restoration of physiological loading of the ankle joint; joint preservation in asymmetric degenerative arthritis of the ankle.
METHODS: Congenital deformities of the distal tibia; acquired deformities of the distal tibia; asymmetric degenerative arthritis with partially preserved cartilage.
METHODS: Absolute contraindications comprise severe nicotine abuse, Charcot arthropathy, peripheral polyneuropathy, relevant peripheral arterial vessel disease, poor local soft tissue condition, acute infection and extensive cartilage damage grade 3-4 in the Outerbridge classification in the complete joint.
METHODS: Medial and lateral open and closed wedge osteotomies and dome osteotomies of the distal tibia are used, and shortening, lengthening and derotating osteotomies of the fibula.
METHODS: For 6 weeks, 15-20 kg partial weight-bearing in a below knee cast or a walker orthosis; full weight-bearing depending on osseous healing after 9-12 weeks postoperatively.
RESULTS: Between July 2012 and May 2017, 15 patients (10 men, 5 women) underwent a supramalleor osteotomy. Average age was 41.8 years (range 17-63 years) and the retrospective average follow-up was 28.7 months (range 3-47 months). Mean preoperative AOFAS (American Orthopaedic Foot and Ankle Society) hindfoot score was 54.3 (range 26-86) and postoperatively a mean of 74.2 (44-100). Preoperatively, 9 patients had varus malalignment and 6 patients valgus malalignment; overall, 4 patients developed complications requiring surgical intervention (26.7%). Osteosynthetic material was removed in 60% of the patients.

Clubfoot is one of the most common congenital limb deformities. Prenatal diagnosis of the condition is essential as it can help treat the malformation as early as possible. We reviewed the recent available literature concerning the current methods for prenatal diagnosis of clubfoot.
The following databases were searched from 1966 to 2015: PubMed, OVID, Cochrane, CINAHL, Google scholar and Embase.
Out of a total number of 197 retrieved articles, after abstract or title page evaluation, 158 articles not matching the inclusion criteria were excluded. The full text versions of the remaining 39 articles were obtained, and their reference lists screened, with the addition of another 5 full-text articles.
Currently, ultrasonography is considered the most reliable method of prenatal diagnosis of clubfoot. Ultrasonographic diagnosis of clubfoot appears more likely between the 18th and the 24th week of pregnancy. Alternative imaging is not indicated. There is no agreement whether to propose foetal karyotyping when isolated clubfoot is diagnosed by prenatal ultrasonography. Early detection of clubfoot should prompt a careful surveillance during pregnancy in order to detect any possible additional abnormalities and, if any of these are detected, invasive testing should be offered.
