Reconstruction of third-degree perineal lacerations in female camels (Camelus dromedarius) using a modified Goetz one-stage repair technique.

This study was designed to evaluate the modified Goetz-one-stage repair technique for reconstruction of third-degree perineal lacerations (TDPLs) in female camels. Fifteen female dromedary camels with TDPL were surgically reconstructed using the modified Goetz one-stage repair using the three-line closure technique. The surgical outcomes, the interval between repair and breeding, and the postoperative conception of the operated female camels were recorded and analyzed. During the 12-month postoperative follow-up period, TDPLs in 14 female camels (93.33%) healed completely by the first intention with mild inflammatory edema and infection in 2 female camels. One camel (6.67%) had a rectovaginal fistula, which was successfully repaired with suturing through the vaginal approach. Of the 15 female camels, 13 (86.67%) subsequently became pregnant through natural mating within 3 to 6 months postoperatively; however, 2 (13.33%) were one was immature and the other was barren which referred for gynecological treatment. The modified Goetz one-stage repair technique was successful in 14 of the 15 female camels after a single surgery, with a low incidence of postoperative complications. This technique is efficient for the repair of TDPLs in female camels, with promising results for subsequent fertility.

Can bone marrow aspirate improve mandibular fracture repair in camels (Camelus dromedarius)? A preliminary study.

BACKGROUND: Mandibular fractures are common in camels, leading to considerable economic losses. This study explored methods of improving mandibular fractures repair, adjuvant with interdental wire, or bone plate fixation. Autologous bone marrow (BM) injection enhances osteogenesis and rapid healing. OBJECTIVES: To investigate the effect of autologous BM aspirate as an adjuvant treatment for repairing mandibular fractures in camels with interdental wire, or bone plate fixation. METHODS: Thirty dromedary camels aged 5-8 years and of both sexes were randomly divided into 4 treatment groups: group 1 (n = 10) treated with stainless steel wire fixation and BM injection at the fracture line, group 2 (n = 10) treated with plate fixation and BM injection at the fracture line, group 3 (n = 5) treated with stainless steel bone wire fixation and placebo saline injection at the fracture line, and group 4 (n = 5) treated with plate fixation and placebo injection at the fracture line. The mandibular fractures were followed weekly for 12 weeks postoperatively to assess improvement and healing based on clinical evaluation, radiographic union scale, and bone turnover markers (i.e., bone alkaline phosphatase, osteocalcin, pyridinoline, and deoxypyridinoline). RESULTS: Compared to other groups, elevated bone turnover markers in group 1 were demonstrated (p < 0.05) on the seventh postoperative day. Likewise, compared to other groups, both clinical findings and radiographic union scale significantly improved (p < 0.05) in group 1 on the 56th postoperative day. CONCLUSIONS: BM aspirate has a promising beneficial osteogenic effect on mandibular fracture repair in camels, most notably when combined with interdental wire fixation.

Diagnosis and treatment of foreign bodies swallowing syndrome in camels (Camelus dromedarius) with special reference to the role of mineral deficiency.

This study describes the clinical presentation of ruminal and reticular foreign body syndrome (RRFBS), and evaluates the effect of mineral deficiency on its occurrence in dromedary camels. Thirty dromedary camels were divided into two groups. Group 1 (control) included 10 apparently healthy she-camels. Group 2 consisted of twenty dromedary camels diagnosed with RRFBS on the basis of clinical, ultrasonographic, hematological, and biochemical examinations. Clinical findings showed decreased appetite and milk yield, tympany, and gradual body weight loss. Ultrasonographic examinations revealed the presence of hyperechoic material with variable degrees of shadowing. Hematological evaluation showed a significant (P<0.05) decrease of the total erythrocyte and lymphocyte count and a significant increase of neutrophils in the camels with RRFBS compared to the controls. Biochemical tests showed a significant elevation in the activity of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), creatine kinase (CK), glucose, creatinine, and blood urea nitrogen and a significant decrease of sodium, chloride, potassium, cobalt, iron, and selenium in the camels with RRFBS compared to the controls. Rumenotomy was performed on the 20 camels as a surgical intervention for treating the RRFBS. By the 6th month postoperatively, all surgically treated camels had completely recovered except for one with tympany and slight swelling in situ. In conclusion, trace element deficiency might play an important role in the occurrence of foreign body ingestion syndrome in dromedary camels. Moreover, clinical, ultrasonographic, hematological, and biochemical examinations are considered as tools assisting in the accurate diagnosis, prognosis, and treatment stratagem for RRFBS in camels.

Mandibular fracture in single-humped camels.

OBJECTIVE: To report the causes and classification of mandibular fractures in dromedary camels and outcome after treatment. ANIMALS: Single-humped camels (n = 116) with mandibular fracture. METHODS: At admission, cause, site, classification, and radiography of mandibular fractures were recorded. Factors affecting fracture healing were analyzed. RESULTS: Biting was the main cause of mandibular fractures in camels, which occurred more commonly in older males (P = .001) than in females. Open fractures were more common than closed ones (92.2% versus 7.8%, P = .0001) and single fractures were more frequent (82%) than multiple and comminuted fractures (18%; P = .001). Fractures were treated by interdental wiring (91.2%) or U-shaped aluminum bar (8.8%) and healing occurred in most (83.2%) fractures. CONCLUSIONS: In dromedary camels, mandibular fracture is most commonly caused by bites and can be successfully repaired by interdental wiring or a U-bar technique with good outcome.

Surgical repair of a ruptured cranial cruciate ligament in a dromedary camel.

A 14-year-old dromedary camel was examined because of lameness of the left hind limb of 3.5 months'duration. The camel injured the stifle joint when it slipped while reclining into sternal recumbency. Radiography did not reveal major abnormalities that could account for the lameness, but nuclear scintigraphy revealed increased radionuclide uptake in the left stifle joint. Intra-articular injection of anesthetic further localized the injury to the area of the left stifle joints, and arthroscopy of that joint revealed rupture of the cranial cruciate ligament. Surgical repair of the ligament was attempted, using an autogenous graft obtained from the tensor fascia lata muscle. Outcome for the camel initially was considered good on the basis of a substantial improvement in attitude, apparent increase in comfort, and decrease in lameness. The tendency for the camel to remain in sternal recumbency after surgery increased the number and severity of postoperative complications. The camel was doing well 9 months after surgery; however, it was euthanatized 16 months after surgery because of a 4-month episode of lameness. Necropsy revealed chronic osteoarthritis and bilateral rupture of the cranial cruciate ligaments.

Spontaneously occurring fractures of the spine in skeletally immature animals.

STUDY DESIGN: Twelve spontaneously occurring fractures of the spin in nine skeletally immature animals were investigated. OBJECTIVES: These fractures were analyzed radiographically, morphologically, and histologically. SUMMARY OF BACKGROUND DATA: The most commonly injured regions were the cervical and lumbar regions. Multiple-level fractures were noted in three specimens. METHODS: Morphologic and histologic examination invariably detected fractures in cases of spinal cord injury without radiographic abnormality. RESULTS: The end-plate physes and synchondroses were found to be the "weak links" for propagation of fractures. Radiographically benign-appearing ring apophyseal fractures were found histologically to propagate from the end-plate physis through the vertebral body via the contiguous neurocentral synchondroses. CONCLUSIONS: The observed morphologic and histologic fracture patterns should provide a better understanding of the probable comparable pathoanatomy of spine and spinal cord injuries in children.

External fixation repair of a displaced comminuted radial fracture in a juvenile camel.

A young female camel had a complete comminuted midshaft fracture of the right radius. The fracture was repaired by external coaptation, which involved 2 full-limb fiberglass casts for 15 weeks. A Thomas splint was placed around the second cast for 12 weeks. The fracture healed in nonaligned configuration, and although lameness was substantial after the fracture had healed, the camel's breeding potential had been salvaged. This successful outcome is an indication that a high-limb fracture in a camel bone (in this case a radius) may be managed by external coaptation and repair by callus formation.
